From initially automating single, repetitive manual tasks to developing a self-aware, self-governing operational model, the journey between these two points is fraught with challenges. To address those challenges, TM Forum’s member group the Autonomous Networks Project (ANP) came together in 2019 to define and standardize the industry’s approach to autonomous networks (AN) and to form a standards developing working group to align and coordinate work in this area. A key piece of this process was to develop a six-step maturity model for AN, against which a CSP’s progress can be measured. In this report we look at some real-world evolutional projects and follow the progress of a hypothetical CSP, AN Telecom, as we detail each step of this maturity model and map some examples of AN evolution against the theory. B ecause some of the projects we have discussed with real CSPs have not been publicly announced, we will use AN Telecom, invented for the purposes of this report, to summarize our findings in hypothetical automation evolution scenarios. The ANP defines AN and the six levels of the maturity model in the following way. 3 What are they? Autonomous networks are the key to making the concept of zero-touch operations a reality. The ANP aims to define fully automated, zero-wait, zero-touch, zero-trouble innovative network/ ICT services. CSPs can use these services for vertical industries’ users and consumers, supporting self-configuration, self-healing, self-optimizing and self-evolving telecoms network infrastructures for telecoms internal users. These users may be spread across planning, service/marketing, operations and management. AN incorporate a simplified network architecture, autonomous domains and automated intelligent business/network operations for the closed-loop control of digital business, offering the best possible user experience, full lifecycle operations automation/autonomy and maximum use of resources. inform.tmforum.org the big picture Simply put, autonomous networks allow CSPs to: Take away the repetitive work that telco staff have performed for decades Maturity model Each level of the maturity model has a set of characteristics describing the evolutionary stage of the CSP’s journey from fully manual to fully autonomous operations: Remove the chances of human error in these tasks and processes Vastly increase the speed at which tasks and processes can be performed Achieve an end-to-end view and awareness of services, aligning service-level information with specific network operations Drive AI and machine learning intelligence into operational decision-making without the need for human intervention Perform self-healing and selfoptimizing improvements as a part of day-to-day operations Offer differentiated new service models and bundles to both enterprise and consumer customers Realize the true potential of 5G and monetize considerable radio access network (RAN) investments. 5 4 3 2 1 0 4 Fully autonomous network The system has closed-loop automation capabilities across multiple services, multiple domains – including partners’ domains – and the entire lifecycle. Highly autonomous network In a more complicated, cross-domain environment, the system enables decision-making based on predictive analysis or active closed-loop management of servicedriven and customer experience-driven networks. Conditional autonomous network The system senses real-me environmental changes and in certain network domains will optimize and adjust itself to the external environment to enable intent-based, closed-loop management. Partial autonomous network The system enables closed-loop operations and maintenance for specific units based on AI modelling under certain external environments. Assisted operations and maintenance The system executes a specific, repetitive subtask based on pre-configuration in order to increase execution efficiency. Manual operations and maintenance The system delivers assisted monitoring capabilities, but all dynamic tasks must be executed manually. inform.tmforum.org the big picture 13% 4% 83% 48% 13% 52% 4% Level 0 48% 35% 32% 32% Level 1 18% Level 2 36% 41% Level 3 CSPs’ progress in implementing automation 14% 41% 23% Level 4 63% Level 5 We don’t see a clear path to this level and don’t have a proposed timeline We see a clear path to get to this level within 4 years We see a clear path to get to this level within 2 years We have reached this level TM Forum 2020 TM Forum’s research shows that CSPs’ progress along this maturity model is perhaps not as advanced as you might think, with none claiming to have reached Level 3 (see graphic above). by taking advantage of AI, big data, cloud computing, IoT and 5G, making services simpler to consume, and by delivering a “Zero X” (zero-wait, zero-touch, zerotrouble) experience. End goal for Level 5 Automation of the enterprise will enable operators to provide AN capabilities in one of two ways: The ultimate goal for AN is for them to support a set of innovative business models and network services that enable the digitalization of vertical industries such as smart cities, manufacturing and autonomous vehicles. In addition, the aim is for them to improve the digital life of consumers through fully automated and intelligent business, ICT and network operations. This is done 5 as-a-service – a one-stop, realtime, on-demand, automated, end-to-end lifecycle of network/ICT services as-a-platform, which will enable ecosystem collaboration between verticals and network/ ICT service providers. inform.tmforum.org the big picture a vision of autonomous networks Smart Industry Smart City “Zero X” Experience • Deliver simplicity to the users • Leave the complexity with the providers As a Service One-stop, real-time, on-demand, automated, E2E full lifecycle network/ ICT services Smart Government Smart xxx... 24/7 Monitoring Standardization Backup & Disaster Recovery Remote Help Desk Online Support ICT Procurement As a Platform Enablement of business collaboration & ecosystem between verticals & network ICT service providers Cloud Services Vendor Management Proactive Maintenance Mobile Device Support Security Solutions Network Documentation Zero Wait Swift Zero Touch • Launch • Delivery • Care • Launch Simplified • Delivery • Care Autonomous Network Agile Operations Zero Trouble • Business Self-healing • Services • Infrastructure All-inclusive Services TM Forum 2020 The graphic above, from our report Autonomous networks: empowering digital transformation for smart societies and industries, shows this vision of AN. ICT functions are centralized and can be selected as modular components of any conceivable future operating model. In this way, CSPs are able to meet current customer demands, but also to pivot quickly towards new, as yet unknown, business opportunities.

Read this white paper to find out more about TM Forum’s drive to provide a common understanding of AN: The key drivers currently leading CSPs to invest in AN 6 inform.tmforum.org section 1: humble beginnings Level 0 Manual operations and maintenance. The system delivers assisted monitoring capabilities, but all dynamic tasks must be executed manually. Level 0 is the state we often describe as traditional, historical or legacy telco operations. At this level, our operator AN Telecom has a vast array of legacy operational and business support systems (OSS/BSS) and network management IT systems – some commercial off-the-shelf (COTS), some developed inhouse and some custom coded by a third party such as an IT vendor, a systems integrator or a management consultancy. 7 Typical characteristics of Level 0: Offline, full manual operations and maintenance Expected effects of Level 0 operations: Awareness, analysis, decision, execution and intent are fully manual. There is no optimization of staffing cost. M any of the systems have been inherited as part of mergers and acquisitions to grow AN Telecom’s geographical footprint or better compete in its domestic market. The company has eight billing systems, 11 different order management systems and more than two hundred other different OSS and BSS systems. Hardly any of these systems have a software link between them, so all transferring of data is done manually by staff, copying and pasting information between records systems and live operational graphical user interfaces. Some consolidation work has been carried out with data migration and database federation, but a great deal of this has been done by a team of around 30 people who have been trained in multiple user interfaces and can support the movement of information between the systems inform.tmforum.org section 1: humble beginnings for processes like service order fulfillment. Much of the work they do is retrospective. Data errors The manual action of inputting the data that allows software systems to run through processes, such as progressing a customer service order or provisioning a new piece of network, is highly error prone. Many of the legacy systems have free type fields, which allow users to input any value. If this value is in a format that the software doesn’t recognize, it will derail any automated process within the system until a user can double-check the data. In the best-case scenario, this process stalls and sits in a redundant state for hours or days. In a worstcase scenario, this process appears to have continued but has stalled and disappeared from sight. This is the cause of order fallout, which costs AN Telecom millions of dollars a year to rectify. Assisted monitoring At this level AN Telecom’s network operations team has a small amount of simple automation built into the network management systems. That automation helps run processes like batch provisioning of consecutive circuits or commissioning new backbone network sections copied from existing routes and the same terminating equipment. The rest of day-to-day operations is done manually by a large group of highly knowledgeable staff. Employing this operations team makes up a large portion of the company’s quarterly opex bill. One of the first areas to shift from passive to proactive IT is network and service assurance systems such as performance monitoring and fault management, because they are mission critical in meeting customer SLAs. 8 drawings stored and shared locally on an exchange server. The manual action of inputting the data that allows software systems to run through processes, such as progressing a customer service order or provisioning a new piece of network, is highly error prone. Swivel-chair operations Having many systems spanning both network and service/ customer operations, each with its own esoteric graphical user interface, requires a large number of staff that are familiar with these applications. In Level 0, being able to progress a service order may require an operative to retrieve information from many systems and provide the correct set of data to their colleagues at the next stage of the process. Failure to get these details right will result in delays which then need manual remedial action. Training and retaining these staff is an expensive process, because they become subject matter experts in a very specific discipline and essential to the business. Static RAN operations The planning, deployment, management and maintenance of AN Telecom’s radio access network has been done in a similar way to a landline network in the 1980s, with paper records replaced with spreadsheets and Load balancing and cell neighbor relations are done by the engineering team on site with mobile test and measurement kits. Cells are set to run, and then not adjusted unless the immediate cell mesh is altered – for example, by the addition of a new macro cell nearby. Weak links At Level 0, AN Telecom has very few direct links between the overarching strategy of the business and the senior leadership team and what happens in operations. Spending in operations is driven by retrospective action and the need to keep up with orders coming in from sales, rather than by any long-term plan to optimize architectures, procedures and spending. Capacity planning A large percentage of AN Telecom’s capex budget is spent on physical infrastructure to build sufficient capacity overhead into its network, which should exceed the predicted needs of sales in the following quarter. Capacity overhead planning is the principle of building and commissioning network that is unused until needed, so it has a large associated capex and opex impact, with no revenue until it goes live. Accuracy in capacity planning has been an expenditure issue for many years: add too much overhead and the total cost of ownership of the network begins to spiral out of control; add too little, and new service orders can’t be met without long lead times, which may result in losing business to competitors. OSS interoperability AN Telecom’s many operational support systems have some custom inform.tmforum.org section 1: humble beginnings code adaptors at the interfaces, through which some data transfer can happen. But a lack of standardization in the development of these systems interfaces means that a significant percentage of data transfers contain errors which are unrecognizable to the receiving application. AN Telecom just accepts this as an eccentricity of the architecture and places more staff on hand to deal with manually pushing the processes through. Data migration projects AN Telecom has assessed the possibility of transferring all its data from tens of systems with hundreds of databases into a single inventory for physical assets and logical connections. Data quality issues mean that an estimated 30% could be transferred automatically and the rest would need a team of data analysts to manually load the information. The project is predicted to take three years and cost tens of millions of dollars. Pockets of automation For many operators in developed economies, Level 0 operations would have been familiar in the 9 1980s. No operators of any notable size or age that we studied in 2021 are still at Level 0, although some start-up interconnect providers and niche B2B CSPs are able to quickly and cheaply run manual, localized operations with a small team. However, this model becomes untenable very quickly as the company scales up and systems are procured to drive some automation. In the late 1980s US operator MCI was beginning its transformational journey by writing custom code to connect its in-house OSS inventory system F&E (facilities and equipment) with live status reports from the network management system. Links were also being coded to connect F&E to various billing systems, so that when a new customer circuit went live a status update was provided by a provisioning engineer. This would transfer the service details in a file into the BSS where it would sit in a job queue to be addressed by a worker in the billing department. This type of automation is still just removing a small step in a very manual process, but if the data quality allowed the automated step For many operators in developed economies, Level 0 operations would have been familiar in the 1980s. No operators of any notable size or age that we studied in 2021 are still at Level 0. to take place it had an incremental improvement on the speed and reliability of the overall service operations function. It took MCI several years to make this first step from Level 0 to Level 1, with a great deal of remedial action on the systems interfaces and code. In the next section we look at the difficulties with these new pockets of automation. inform.tmforum.org section 2: starting to join up the dots Level 1 Typical characteristics of Level 1: Online, assisted execution. Assisted operations and maintenance. The system executes a specific, repetitive subtask based on pre-configuration in order to increase efficiency. Expected effects of Level 1 operations: Awareness and execution are assisted by the system. Actions of awareness, execution and intent/experience can be online, recorded and traced. Part of staff time can be saved and more can be focused on analysis and decision-making. In Level 1, AN Telecom has invested in the automation of basic repetitive tasks. Its automation strategy has been based on a low hanging fruit principle, automating the simplest processes that will return the most benefits in the short term. 10 T he processes and subtasks that AN Telecom is addressing in this first wave of automation are based within specific operational functions – for example, some software scripts are developed to automate provisioning of circuit channels associated with predefined ports on transmission equipment. This reduces the total time that the operations and engineering team take to activate a service at the end of the service fulfillment process. Data quality becomes an issue in automating this process. If the modelled representations of the network in the provisioning systems do not match real-world allocations, an engineer must be sent to the site to audit the physical cabling and update the system. This first wave of automation triggers many large-scale audit programs as it becomes obvious inform.tmforum.org section 2: starting to join up the dots key drivers for autonomous networks Improving customer experience Delivering new services Efficiency gains/lowering costs Faster time to market Zero-touch partnering (e.g., with hyperscalers or enterprises) 0% 20% ■ Very important 40% ■ Moderately important 60% 80% 100% ■ Not as important TM Forum, 2021 that the data quality in the records of the physical network topology is poor, hindering attempts to automate processes. Robotic automation Many communications service providers (CSPs) went through the scenario that AN Telecom is experiencing in the 1990s and 2000s, but in present-day operations the mass automation of high-frequency, manual, repetitive, rules-based processes can be done with robotic process automation (RPA). RPA is a low-code, low-cost option for CSPs to automate high-volume manual processes, delivering cost savings, efficiency, accuracy and transparency. RPA is well suited to quick wins and straightforward use cases – such as service order provisioning, service assurance and BSS checks – and in a telco with many fragmented OSS/ BSS and network management systems this quick win can translate instantly into improved operational efficiency. 11 But in the long term, RPA is not an holistic, forward-looking operational approach and is more of a way to remove manual processes in the short term. As George Glass, CTO of TM Forum, says in our recent report on process automation: “All you’re doing is treating the symptoms and not fixing the cause of the problem. Frequently you end up with process fragments and not a standard set of processes.” Instead CSPs should look towards the TM Forum Open Digital Architecture (ODA), which is a blueprint for modular, cloudbased, open digital platforms that can be orchestrated using AI. Read these reports for more information on AN: August 2021 | www.tmforum.org Author: Ed Finegold, Contributing Analyst Editor: Joanne Taaffe, Editor in Chief of Inform CX as a key metric TM Forum’s 2021 survey on AN asked our respondents to identify the key drivers for implementation strategies (see chart above). While many of the popular responses were about new services, operational efficiency and faster time to market, the top answer was improving customer experience (CX). This reveals something of a change in thinking about what CX is, how we measure it and how we can positively influence it and the nature of AN. CSPs are not just thinking about AN as a network advancement, but as an overarching methodology to revolutionize service-centric operations and achieve vastly more diverse business goals. CX is a metric that can be influenced from any point in that methodology, and incremental improvements all add to a better way to provide services. inform.tmforum.org section 2: starting to join up the dots The wider picture In Level 1 AN Telecom is thinking about its wider approach to processes like order to activation. Many different legacy processes are in place in parallel, making the task of automating specific tasks or functions difficult. The company is looking at how the OSS processes in service ordering, fulfillment, activation and assurance could all ideally work together as one entity, while retaining some functional separation. This more holistic approach to service management would have a positive domino effect on the network systems and processes below when trying to drive more automation into the whole system. In a recent conversation at TM Forum’s Digital Transformation World Series 2021, Telia’s Head of Products and Production Services, 12 Ida La Spisa, explained that this problem is still commonplace. She explained that as recently as two years ago Telia had at least “six different ways of doing order to activation” and “proposing products to customers”, with six or more order-to-activation stacks across B2C and B2B markets in different countries. These were targeted for transformation, which also entailed rationalizing and unifying product and customer data and processes across all six countries. While transforming order-toactivate processes, La Spisa said Telia has also made sure to “fully take into account service assurance across the countries we operate” and to “clean up assurance aspects, rather than seeing it as an appendix to our processes”. She explained that Telia fully automated both its customer SLAs and “the internal operations levels we need to assure those services for our customers”. Telia also changed the ways it worked, embracing Agile and DevOps across the company. The smaller releases allowed for a faster pace. Although that has introduced some new challenges, La Spisa admitted it “gives the ability to adjust deliveries continuously”, with new production releases every two weeks. This also extends to Telia’s vendors, La Spisa said, with which it conducts common governance and from which it expects buy-in throughout the transformation process. In the next section we look at the gathering pace of the transformational journey as we look at the first closed-loop operations stage and the benefits of DevOps methodologies. inform.tmforum.org section 3: the leap to closed-loop operations Level 2 Typical characteristics of Level 2: Static rule/policy-based automation. Partial autonomous network. The system enables closed-loop operations and maintenance for specific units based on AI modelling under certain external environments. Expected effects of Level 2 operations: Execution is automated. Some awareness and analysis functions can be accomplished for certain scenarios based on static (human predefined) rules/policies. Part of staff time can be moved away from simple and repetitive work on data collection, pre-processing and analysis. Level 2 is the state in which many communications service providers (CSPs) currently find themselves worldwide. This point on the transformational journey means that an operator has automated some significant portions of their network operations and has process automation workflows in place through sections of the operational and business support systems (OSS/BSS) in service operations. 13 A t this point, our fictional CSP AN Telecom is focused on working with several systems integrators and its IT vendor partners to link together some of the business processes that it relies on for streamlining ordering and fulfillment. As it is aware of the potential benefits of automation across the whole structure, work is going on in most parts of the company to automate existing manual processes. In the network, AN Telecom is starting to work more extensively with its IT vendors to insist on more automated provisioning for orders which involve new network assets or changes to the existing configuration. This should be for both physical network components such as transmission equipment and cabling and for the logical allocations in the network management and inventory software systems. inform.tmforum.org section 3: the leap to closed-loop operations systems & processes most in need of automation 57% Service management & assurance 43% Network planning & design 35% Network build-out 30% Customer experience management 29% The fulfillment process 11% Partner management 0% 10% 20% 30% 40% 50% 60% TM Forum, 2021 Automation priorities TM Forum’s 2021 survey of which systems and processes are still most in need of automation shows that service management and assurance is now the top priority followed by some more network-centric categories (see chart above). This is telling of the current trend to focus on servicelevel systems and processes in the deployment of 5G. apparent that monetizing new 5G SA service models is only possible with extremely high levels of automation in the BSS and OSS, driving towards zero-touch operations. It is also apparent that this is the area that has been neglected in terms of attention and investment, so many initiatives are underway to redress the balance. that trend reflected in the staffing patterns of CSPs. The balance of the work being carried out within that workforce, however, is changing as fewer operations staff are needed to fight fires and more IT-centric staff are needed to operate systems and work on incremental improvements in the continuous integration / continuous deployment (CI/CD) DevOps model. Impact on workforce At Level 2, CSPs start to feel this influence of increased automation on their workforce as network operations personnel start to shift their roles from primary troubleshooters to monitoring and handling exceptions. In our survey, 47% of respondents said they consider this scenario highly likely as shown in the chart below. Automation inevitably has an impact on the workforce of any business as manual tasks carried out by people are reduced and replaced with IT. But in recent years the thought that automation will put people out of work has abated somewhat and we are not seeing CSPs are keen to align their BSS with the new technologies and capabilities that have been driven into the network over the past few years, under the banner of 5G, virtualized networks and the telco cloud. With standalone 5G (SA 5G) on the near horizon it is becoming changing roles in operations Roles will change from operations to monitoring & handling exceptions 47% Roles will shift from operations to designing, training & explaining 34% There will be little change 32% Roles will be eliminated 11% 0% 5% 10% 15% 20% 25% 30% 35% 40% 45% 50% TM Forum, 2021 14 inform.tmforum.org section 3: the leap to closed-loop operations Accelerating change Undertaking a large-scale DevOps program requires significant transformation over a multi-year period, and for many CSPs it has been difficult to make a compelling business case. A large impact on AN evolution and on workforces has been the introduction of DevOps methodologies into telco operations. There are several challenges for CSPs when making this transition, however, including a significant debt of legacy technology, an historically rigid divide between IT and network teams, and the fact that most software is procured from vendors rather than developed inhouse. CSPs have therefore been relatively slow to adopt DevOps. To date, most of their efforts have focused on customer-facing digital initiatives, which tend to be relatively standalone and built on a cloud-native architecture from the outset. drivers for DevOps within CSPs One example of a business that has benefitted from a DevOps approach is Softbank Corp. Working with technology vendor Red Hat, Softbank developed a global IT platform strategy supported by Agile and DevOps approaches. Beginning with an artificial intelligence (AI) project as a pilot, Softbank has now expanded DevOps to more than 50% of its IT projects and seen significant increases in the cadence of its software releases. Undertaking a large-scale DevOps program requires significant transformation over a multiyear period, and for many CSPs it has been difficult to make a compelling business case to embark on a broad initiative. The exception has been in some of the tier-1 CSPs, which are deploying software-defined networks on cloud-based platforms and see DevOps as a key element of delivery at scale. Yet as 5G, edge and other future networks evolve, it is inevitable that DevOps principles will be an essential part of the rollout. CSPs will therefore benefit from initiating or growing their use of DevOps now, in conjunction with cloud and network transformation, rather than seeing them as separate entities. DevOps In the next section we look at the evolution towards large amounts of automation and the use of the cloud across service and network operations. Cloud-based b architectures Digital t l transformation Software-defined networks TM Forum, 2021 15 inform.tmforum.org section 4: digitally transformed cloud operations Level 3 Conditional autonomous network. The system senses real-me environmental changes and in certain network domains will optimize and adjust itself to the external environment to enable intent-based, closed-loop management. In Level 3, communications service providers (CSPs) have likely invested hundreds of millions of dollars on IT, systems integration and management consultancy to streamline their operations enough to begin aligning tightly with business intent and have an automatically reactive network and service operations ecosystem. This is the point at which the core concepts of digital transformation come into play and start to make a significant impact on CSPs’ cost structure, operational efficiency, agility and responsiveness. 16 Typical characteristics of Level 3: Dynamic rule/policy-based automation. Expected effects of Level 3 operations: Awareness, execution and most analysis are automated. Decoupled common rules/policies/AI models which can be dynamically updated. Some automatic decision-making can be achieved under human predefined rules/policies. P ushing into Level 3, CSPs are relying on the efficiencies, agility and scalability of the cloud to add more dynamic IT capabilities to their operations. Software in OSS, BSS and network management and orchestration are developed with the cloud in mind. As such their microservicebased open architectures, modular format and open API frameworks allow them to interoperate across multiple domains within the operational framework. Data passed between these systems, both within the operator and outside to a partner ecosystem or customer’s IT infrastructure, become the life blood of 21st century telecoms operations. There is, however, some way to go on the journey to cloud-native IT systems and data storage, as shown by our recent report Cloud migration: Assessing strategies (see pie chart on page 17). inform.tmforum.org section 4: digitally transformed cloud operations percentage of IT workloads CSPs have migrated to public cloud 1% 7% 15% 40% An open architecture with open APIs is essential to orchestrating industry vertical applications and underlying network capability in ways that result in a compelling, differentiated and quality customer experience. Moreover, service providers need to deliver such applications and services from higher up in the value chain to avoid missing out on the lion’s share of revenue from industry verticals. these stores and systems is being groomed to meet data quality standards of accuracy, validity, reliability, timeliness, relevance, completeness and compliance with customer/partner regulations and statutory obligations, as established by an information or data quality policy. The start of zero-touch 0-10% Data management 10%-25% At this point AN Telecom is becoming more involved in TM Forum’s Open Digital Architecture and the Architecture Toolkit to refine its information model framework, build standardized architectures and align its business process frameworks. The company is paying specific attention to how it uses data internally and how it can expose operational data to its partners and customers in a secure and open manner. In Level 3, AN Telecom has the beginnings of what we consider to be zero-touch service operations. A customer can order a service package or element from the online self-service portal (or any other channel of their choosing), which is enabled by cloud-native omnichannel BSS. The order management system can then trigger an automated workflow down through the OSS by using a centralized product/service catalog as a single data source to fulfill the service. Additional workflows are triggered by the service orchestrator, which follows the service fulfillment process through checks and activation and will tell the network orchestrator what is required in network resources to fulfill the order. Information is being gathered from all systems and stored in a centralized data repository – usually a dictionary or metadata library – as an information library. All of AN Telecom’s systems will have the capability to store logs and pertinent information within an analyzable repository. Information classified as personally identifiable will be managed through the enterprise anonymization rules prior to being committed to any repository. This is where, at Level 3, manual involvement from network operations teams is significantly reduced. The process of completing the order, activating the service, and triggering instantiations of BSS elements like service assurance and rating/charging/billing/partner settlements in accordance with the customer’s SLA, are now carried out by automated workflows. This whole order-to-cash process is not yet zero-touch, but is showing signs of large elements of automation. Analytical systems are being used to extract required data from the repository and present it to the user in the most appropriate way. Information moving around In the next section we look at how the highly autonomous networks of Level 4 can drive new business opportunities for CSPs and the role that AI and machine learning will play in AN. 37% 25%-50% 50%-75% More than 75% TM Forum, 2021 Orchestration needs Our fictional CSP AN Telecom is investing in orchestrationbased software for both network and service operations. The company has developed a service orchestration strategy which will, in the first instance, enable it to add intelligent overarching management and control to its own internal operations, and ultimately to orchestrate the operational requirements of partners in new service model value chains. Increasingly, service fulfillment and assurance are being more tightly integrated and becoming part of the larger service and network orchestration process – or dynamic orchestration – ensuring the agreed intent of the customer service is maintained over its lifecycle. As the network evolves with 5G and becomes cloud-native or at least interconnects with cloud-native networks, and services become 17 more ecosystem-centric, fulfillment must have the ability to orchestrate across different domains and communicate with multi-party systems. inform.tmforum.org section 5: new business opportunities Level 4 Highly autonomous network. In a more complicated, cross-domain environment, the system enables decision-making based on predictive analysis or active closed-loop management of service-driven and customer experience-driven networks. Highly autonomous network and service operations have been the goal for many CSPs for the past two decades. Rapidly evolving computing and IT development have driven the industry towards this being a reality rather than a pipe dream. One key feature of Level 4 is the proactive or predictive nature of the software and systems taking on a more holistic nature as the crossdomain integration intensifies. 18 Typical characteristics of Level 4: AI-assisted automation capable of continuous learning and rapid evolution. Expected effects of Level 4 operations: Awareness, analysis, decision and execution are automated. Intent/ experience-driven closed-loop control can be accomplished for certain scenarios under human supervision in emergency situations. Most of the staff time can focus on expert experience, AI model management and novel or unsupported scenarios. I n Level 4, our fictional operator AN Telecom is investing heavily in cloud-native solutions throughout its operations. It is driving initiatives to connect AI and machine learning intelligence to provide an end-to-end view of the operational architecture. This provides much more interlinked decision-making at all levels and tightly aligns customer-facing business decisions with network disciplines to optimize planning and runtime functions. AI is the best option It is becoming apparent that AI is the best option for telcos processing extremely large data sets that combine heterogeneous data from multiple sources, and where multi-domain or crossfunctional correlation is required. AN use cases are driving interest in the concept of AIOps, including those instances where AI is not part of the automation architecture. inform.tmforum.org section 5: new business opportunities Platform-based IT If operators are prioritizing autonomous functions…for select use cases, you end up with different operators, running different types of business, for different groups of customers, under different regulation guidelines.” Given the complex and often disparate state of most operations environments, CSPs can use basic criteria for automation to determine where to start. Most of the hard work is practical and detail oriented, but AI/machine learning at Level 4 on our maturity model will begin to perform a great deal of the heavy lifting when it comes to data crunching and deriving actional insights from extremely large and dense data sets. A recent TM Forum Catalyst proof of concept project called AI empowers 5G intelligent operations sought to demonstrate how CSPs could achieve AN Level 4 by 2025 and specifies the objectives and approaches. 19 A platform-based IT architecture enables the concepts and thinking of modern software architectures – such as service-oriented architecture, modular software components, software contracts and microservices – to evolve and develop OSS/BSS IT solutions. Platforms can set a governance boundary around a set of current TM Forum-defined Open Digital Architecture functionalities such that they can only be accessed via defined Open APIs. In this context the platform model decouples the platform’s users from its architects, which leads to the modularity, isolation and reusability that are prerequisites for agile solutions. This approach also enables the internal platform implementation to evolve without changing the exposed platform capabilities, which enables internal IT rationalization, improvement in agility and reduction of capex and opex costs without affecting the platform consumers. Collaboration is key In a 2020 TM Forum Digital Transformation World Series event presentation, Dr. Che Haiping, Chief Digital Transformation Officer at Huawei, identified the need for industry partners to develop “deeper and broader collaboration to push the autonomous network initiative forward” by defining a reference architecture using a common technology approach and unified language. Lingli Deng, Lead Researcher and Technical Manager at China Mobile, also warned that for any operator to achieve Level 4 or even Level 5 network autonomy, the industry needs to address a serious and all-too-familiar roadblock: fragmentation. Deng said progress from Level 0 to Level 5 will likely happen in two stages: first, improving functional requirements for specific, highpriority use cases; second, scaling those functional requirements to cover all remaining scenarios. She said the problem is that the activities in stage one are leading to fragmentation, which makes it difficult to scale autonomous functionality across all scenarios. “If operators are prioritizing autonomous functions…for select use cases, you end up with different operators, running different types of business, for different groups of customers, under different regulation guidelines,” she explained. Lingli said the industry needs an open collaboration platform to “build, test and certify a common, case-agnostic, functional architecture with open implementation and open standards”. Such an architecture, she added, “could be used to identify common requirements from different use cases that can be applied to different operator scenarios”. It is this fragmented approach that we see in levels 3 and 4 that hold CSPs back from progressing to Level 5. In the next section we look at the final stage of the currently defined AN journey, into fully autonomous operations. inform.tmforum.org section 6: the future operating model Level 5 Fully autonomous network. The system possesses closed-loop automation capabilities across multiple services, multiple domains (including partners’ domains) and the entire lifecycle. Typical characteristics of Level 5: Auto-evolution, full autonomy, all scenarios. Expected effects of Level 5 operations: Awareness, analysis, decision, execution and intent/experience are autonomous. The whole autonomy mechanisms, including expert experience and AI model management, can be auto-evolved for all scenarios. Staff time is only needed to generate intent and monitor the progress and status. At Level 5 AN Telecom is at the pinnacle of our story outlining the journey to autonomous network operations. The company’s cloud-based, fully automated operational platform is now capable of entirely zero-touch operations. An order can be placed in the customer’s self-service portal, triggering intelligent automated workflows which will percolate down through AI-powered service operations software in operational and business support systems (OSS/BSS). From there service activation processes ensure that the software-defined network has all the specific information it needs to provide personalized service characteristics, and ultimately trigger revenue management arrangements and customer notifications. AN Telecom is using the TM Forum Autonomous Networks Toolkit to fine-tune its operational configurations. 20 A s we have covered many of the core concepts of automation on the journey to Level 5, it is worth examining the profound impact on telecoms if the operational platform were truly capable of managing its own evolution from this point onwards. The heavy native use of AI and machine learning that is ingrained in every aspect of the company is also joined together in an overarching master control, inform.tmforum.org section 6: the future operating model The heavy native use of AI and machine learning that is ingrained in every aspect of the company is joined together in an overarching master control. 21 which can imagine highly complex scenarios involving both business challenges and operational capabilities, without these two concepts being approached in isolation. As such, it is possible to deliver continual selfoptimization towards goals set by the operations team. Actionable advice can also be pushed from the live AN into DevOps processes to continually improve the constant development cycles of IT systems and architectures. In the next section we look at the key changes CSPs are making to drive their transformational strategies using AN. For more whitepapers, guides and videos on AN take a look at TM Forum’s Autonomous Networks Project. inform.tmforum.org section 7: make it happen – driving transformation through autonomous networks The journey we have mapped out is a complex proposition for any operator and will be different for every company. Our research has shown that there are several common factors essential for a successful autonomous networks (AN) strategy, and they align closely with the broader evolutional changes taking place within communications service providers (CSPs) in the TM Forum member community. Here we summarize the key changes that CSPs are making to drive their transformational strategies using AN: Move to the cloud End-to-end thinking Data management The use of the cloud, both for a new medium in which to move essential data around operational frameworks and to move to cloud-native IT systems, is the basis for any longterm AN strategy. Maximizing elasticity, agility, scalability, and fundamentally altering operational cost structures, are essential characteristics of the evolved CSP’s infrastructure. Making the leap from traditional manual telco operations to AN requires CSPs to abandon the idea of islands of functionality and adopt a more end-to-end approach. Customer-facing BSS systems, and systems down in the depths of the network, need to have an awareness of the holistic goal needed to provide services. We are seeing that an overarching approach to data governance and management is very beneficial for many CSPs in Level 1 of their AN journey. The old approach of trying to harmonize disparate data types by using adaptors at the systems interfaces has shortcomings that can lead to repetitive failures in automation. Standards-based IT systems are combating these problems for large multivendor environments. 22 inform.tmforum.org section 7: make it happen Automate everything Adopt a wide platform Trends like robotic process automation (RPA) are currently accelerating the transformational journey for many CSPs as even the smallest repetitive task is automated, shaving off opex and speeding up processes. The concept of platform that AN enables should not just be seen as a concept within CSP operations. The new business value chains for digital services and models like IoT will require the operator to have automated, orchestrated workflows interacting across other companies’ IT domains. Open APIs and common software frameworks are required to make the platform model successful. Protect your workforce Use technology cycles as a circuit breaker The first few years of the cloud era of telco operations will be typified by a shortage of the right kind of skills in the global workforce. As CSPs are training and building teams of IT-focused people, it is in their interests to retain this pool of people and acquire more where possible. 23 Refine orchestration strategies Several CSPs with service orchestration strategies in their OSS/BSS told us that the hierarchical proliferation of orchestrators they currently have is causing problems for end-toend service operations. They are refining these orchestrator stacks in readiness to supply network slices in standalone 5G. Simplicity is apparently the key. The evolution to 5G has shown that the introduction of fundamentally different technology, such as softwaredefined networks, allows CSPs to eliminate classic telco problems, as long as they don’t simply replicate old processes and business models. Partnering with external IT specialists is becoming more commonplace for CSPs looking at how digital natives and companies like hyperscalers and digital retailers construct their IT stables. inform.tmforum.org additional features & resources 25 | Huawei iMETHOD Framework Realizes Operations Transformation for CSPs 30 | BMC: Evolving Service Assurance to Support Future Autonomous Networks 33 | TM Forum Open Digital Framework 34 | TM Forum research reports 35 | Meet the Research & Media team 24 inform.tmforum.org SPONSORED FEATURE Huawei iMETHOD Framework Realizes Operations Transformation for CSPs SHIFT to Service-centric transformation 5G network deployment is on the rise. Coverage density of 5G compared to 4G means 10x more connected devices per square kilometer of network, compared to 4G. The challenge here is that the shorter range of 5G means more network sites to operate and maintain. As more devices get connected and become clouddependent, hardware and software decoupling introduce more complexity to manage, which leads to an increasingly complex network operations environment. In such a landscape, manual and legacy approaches to Operations can no more scale. With 5G enabling multitudes of industries to embrace digital transformation, the need for stricter SLAs for end-to-end services has become pivotal to business success. Deterministic networks that can be programmed to meet stricter SLA reliability requirements demand real-time and proactive assurance. It is clear that traditional operations environments lack adequate network quality measure rules, thus 25 making it difficult to evaluate and maintain network conditions to support consistent business SLAs. The shift to a Service-centric approach transforms the isolated and passive assurance model built on manual fault and performance management. It ushers in a model that facilitates sharing operations information, accurately processing floods of alarms and data, and effectively identifying and processing service impact intime. This presents an opportunity to meet the requirements of deterministic connectivity business. In a deterministic network assurance model of operations, the complexity related to network scale, network structure, service types, and network SLA requirements are managed with a new framework that embodies digital and intelligent automation. ADOPT a Digital intelligent Operations transformation Framework (CSP) into Digital Service Providers isn’t an option anymore. B2B models will drive new and emergent business opportunities for Service Providers to mine. Innovation, organization culture and process transformation will play key roles to enable adoption of digital and intelligent Operations. This evolution will transform the humancentred Operations paradigm to one that brings man-machine collaboration to the Operations workforce. A traditional Operations approach is persistently fraught with “firefighting” and continued pressure to manage cost efficiency. In an era of growing industrialization, new network technologies, better customer experience and SLA guarantees, an operations transformation framework like iMETHOD is essential to deliver new B2B models, and assure service revenues. Digital transformation of Communications Service Providers inform.tmforum.org SPONSORED FEATURE iMETHOD: A best-practice digital Operations transformation Framework, defines key features for next generation service-centric Operations. The iMETHOD Framework with the Six Key features of NG Operations iMETHOD, an alias for intelligence and six key features of NG Operations, defines an intelligent approach needed to capitalize on the value of digital technologies and growth of trends beyond traditional connectivity business. It unlocks effective Operations delivery and operationalizes the next generation of Service-centric Operations. Huawei’s iMETHOD framework can enable service provider Operations teams to acquire key capabilities that leverage data and AI to support digital business agility, operations intelligence, and achieve higher levels of Operations automation. The following section defines what the iMETHOD acronym means to a service provider. intelligent Integrate data and AI platforms into Operations domains to facilitate lowering the threshold for open use of AI in Operations activities.

This is key to achieve higher levels of intelligence and automation. Hyperautomation (HA) Embrace hyperautomation (HA) approaches to combine automation technology. Prior to HA, robotic process automation (RPA) and iBPM were used independently. By adopting an HA approach, RPA, iBPM, AI/ML and other automation technologies can be combined to scale Operations automation and capitalize on data to improve cost savings, boost productivity and attain efficiency gains. One Trustworthy DevOps (OTD) Orchestrate trust in the adoption of DevOps by employing the use of ‘Low Code/No Code’ platforms in order to successfully merge priorities and goals of both developers and operations teams and achieve a cohesive DevOps effort. OTD facilitates one stop orchestration of data, 27 ADC 4 4 processes, applications, UI and API across design and runtime of Operations domains. Deterministic Network Assurance (DNA) Assure Operations reliability for all networks by correlating 5G service performance indicators with real customer service quality, and experience indicators. This can be achieved through use of high-precision simulation that connects SLA guarantee and target performance requirements together. In the case of B2B customers, deterministic network needs can support near realtime intelligent automation, and service-centric closed-loop assurance solutions. These solutions can leverage expertise and AI models to accurately predict and detect service interruptions and performance deterioration events, which effectively identify servicerelated risk-events in advance. This guarantees that CSP assurance teams can achieve reliable network assurance. Huawei AUTIN realizes the key features of iMETHOD to support CSP business agility and digital intelligence transformation Huawei provides the AUTIN platform using cloud computing and microservice architecture to facilitate seamless development and operations of digital services. AUTIN enables agile network digital transformation with the following capabilities: Providing a series of cloudenabled services for CSP network operations and management, business process management, asset and resource management, and fault and performance management. Enabling studio-based development and operations (through an App Dev Centre) of Operations software components. This empowers app developers / designers to inform.tmforum.org SPONSORED FEATURE collaborate together through drag-and-drop gestures, leveraging AUTIN’s Low Code/ No Code features. processing capabilities to automate service analysis, service decisionmaking, service recovery, and service verification. Improves network experiencemanagement enabling capabilities by intelligently managing, altogether, assets, fault, performance and work orders etc. Step 1 (Optional): Automate traditional fault management processes for Operations efficiency Brings artificial intelligence, hyperautomation, data processing, and knowledge management components together. EVOLVE with Options Huawei Service and Software offers a two-step path to address the typical evolutionary needs of CSP Operations. This two-step path provides the option to address near term Operations targets of improving traditional Operations process efficiency, and sets up CSPs in readiness to advance towards hyperautomated intelligent Operations targets. With traditional fault management workflows, where point-topoint data source for processes are used, AUTIN can inject digital technologies like AI and ML into Operations processes to intelligently improve fault association, and achieve automation of Operations fault handling. This is helpful when there is a need to effectively improve, say, alarm handling efficiency. By overlaying event management processes into Operations workflows, we are immediately able to harness data from diverse sources, analyse and deduce service impact awareness, and proactively inform remedial actions. The overlay of event management is aimed at becoming more servicecentric in defining, establishing and managing Operations objectives. This enables higher automation while fostering closed-loop event 28 Fault management in complex heterogenous networks and 5G sites with multi-RAT can meet a slew of challenges– like having to handle a large number of crossdomain faults, and need to rely on human-experience for fault management. In such network environments, AI-based fault analysis capabilities can improve fault handling automation to reduce workload and increase the speed of Operations personnel activities. Huawei’s Automatic Alarm Behavior Discovery (AABD Pro), a component of AUTIN, can provide self-assuring capabilities, using AI algorithms and expert experience to mine fault propagation relationships using three functional capabilities: 1) Fault Propagation Diagram Construction (FPDC) based on data mining algorithms; 2) Spatiotemporal Clustering; 3) Root Cause Inferencing (RCI), based on both FPDC and expert experience. In Operator X in China, AABD use across multiple domains (wireless access domain and transport domain) for self-assurance and service management, of mission critical multi-vendor backbone switches and 4G network elements, resulted in remarkable business value, including: vastly improving fault clustering accuracy by 90%; dramatically increasing accuracy of RCI in network elements by 93%; 7% decrease in number of wireless trouble tickets. Step 2: Leverage Intelligent Event Management (iEM) solution to realize Service-aware Operations Huawei iEM is a key cloud-enabled solution developed and run on the AUTIN platform. iEM deploys all key features of iMETHOD to transform the traditional fault management or performance management paradigm. By using multidimensional data, iEM solution can identify events and combine its advanced technologies (e.g AI, RPA, RBA etc.), using hyperautomation approaches, to handle changes in service behaviour, service operation and service impact. This achieves greater efficiency in understanding the network. Anomalous events indicate early warning signs to potential service impact, or flag already impacted services. These events can span multiple domains, systems, devices etc., and can come from a variety of data types and sources. In a DNA model, streamlining data and Operations break-points requires focus on problems that affect services in a timely manner. This means quickly identifying and handling these anomalous events in a timely and closedloop manner. Through use of advanced technologies, closed-loop processing of anomalous events, and TKD (to reconcile rules, policies, and insights), iEM can use its recommendation engine to advise actions that mitigate anomalous events based on closed-loop processing of data. This ensures catching and handling anomalous events before they result in failure or major problems. Also, knowledge models in iEM are continuously updated to adapt to event processing changes. This adaptation reduces repeat processing with ‘possible root cause’ suggestions and ‘resolution inform.tmforum.org SPONSORED FEATURE recommendation’ that improve efficiency of event handling. The use of knowledge models reduce dependence on human-skills in managing complex networks, which results in improved network maintenance efficiency. iEM is bringing outstanding value proposition to service providers across the globe. It is helping to: Improve the efficiency of Operations workforce by enabling CSPs to automatically identify faults in complex network environments based on AI algorithms. On average, iEM 29 achieves accuracy of 85% faults detection rate every 5 minutes. Increase effectiveness of fault demarcation through automation of expertexperience rules. In active deployments, average fault demarcation accuracy is greater than 80%, with average demarcation time shortened from 60 minutes to 15 minutes. MTTR of typical faults is reduced by 35%.

As network environments become more complex and dynamic, CSPs are already moving to deploy intelligent, interconnected, automated systems that help reduce reliance on human involvement and optimize processes across the technology environment. As network operations tasks are shifted to these autonomous systems, staff members can turn their full attention to matters and responsibilities that require human judgment, while operators drive competitive differentiation through agility, customer centricity, and actionable insights. Ultimately, high levels of autonomy within the network will allow the network to make decisions without human interaction via policy, AI, and closedloop activity. A be done by the network, and to determine whether Y needs to change based on dynamic factors in the network environment. As this transformation proceeds, we’ll also see a shift in the way automation is implemented. Traditionally, automation has been used to automate discreet tasks and activities through deterministic logic: see X, do Y. While this can be effective as a tactical shortcut, it fails to capture the context and purpose for doing Y. It remains the operator’s role to translate what’s needed by the business into what needs to Modern automation takes a less deterministic approach, focusing on the goal rather than the tactic. In this intent-driven model, the system begins with the intent—e.g., maintain service at quality X—and undertakes activities as needed to achieve this outcome. This shift reflects a change in the role today’s CSPs need automation to play. Beyond increasing operational efficiency and reducing human error—though these remain important—operators need to be able to avoid and predict issues, and anticipate changing capacity demands, in time to prevent service degradation from affecting customers. s the six levels of network automation discussed by TM forum make clear, the move to a fully autonomous network can’t be accomplished in a single step. Instead, CSPs are making incremental moves from manual operations and maintenance through increasing levels of AI assistance across a broadening scope of tasks and domains. 30 To implement this model in a network context, CSPs are deploying closed-loop automation in which real-time analysis of traffic, faults, and resource availability is leveraged to deliver the intent of consistent service quality and reliability. To fully close these loops—and to realize the vision of fully autonomous networks—CSPs will need to evolve their approach to service assurance at the same time. From operator support to true autonomy Closed-loop automation potentially spans multiple, historically separate technologies and operational processes which need to operate together to deliver a given service. To date, the automation deployed in this systems has been strictly inform.tmforum.org SPONSORED FEATURE tactical—Level 1 or 2, to use the maturity model outlined by TM Forum. In other words, they remain primarily operator support systems, designed and focused on supporting human-driven activity within operations. For example, in service assurance: Fault management has focused on tactical automation to improve visibility of critical faults in a network, but still remains focused on a human operator consuming and responding to the resulting alarm. Trouble ticketing has focused on supporting NOC/SOC-delivered workflows to manage disruption in the network, and remains orientated around providing an optimal user experience for human operators. Change management processes are highly manual, still driven, managed, and in many cases executed by a human operator. Advancing automation in the network requires that these associated processes adapt in tandem to reflect a more machineto-machine future, rather than continuing to focus on human interaction. Indeed, it will be very difficult for CSPs to achieve higher levels of maturity (Levels 5 or 6 in the TM Forum model) without service assurance being significantly adapted to support greater closed-loop automation. For example, without highly automated, context aware, and riskbased change management, gains in automation at the network may be constrained by an overly manual or rigid change process. Advancing automation maturity to transform service assurance Improving automation maturity beyond the low levels typically found in service assurance 31 processes will transform the way these processes are delivered. Taking resource trouble ticketing as an example: At Level 2, mundane and repetitive activities will be semiautomated, such as the creation of trouble from alarms and the correlation and grouping of multiple tickets to identify common or wider issues. High-volume, low-complexity issues will be increasingly automated, either fully or as operator-guided activities. This is an extension of existing processes rather than a true transformation, and likely as far as you can go without adapting processes. At Level 3, specific ticket journeys are completely “lightsout,” with full automation of issue creation, assessment, diagnosis, and remediation. Specific types of troubles will be eliminated, as the network resolve these issues automatically without recourse to fault/trouble processes. At Level 4, most mundane, high-volume ticket activity is managed directly within the network, resulting in significantly fewer tickets needing operator involvement. Those that do include highly complex faults or issues that cannot be managed by conditional network automation, often spanning multiple technologies or locations; those falling outside of existing intent driven automation; and those requiring hands-on attention, such as a hardware failure in a remote site. Faults and issues resulting from failed automation may require human interaction as well. Aspects of these exceptions can still be automated, but Service Assurance today, tomorrow and in 5 years Download TM Forum’s eBook: Service Assurance Steps Out of the Shadows may be at a lower level of maturity, such as the automation of “truck rolls” for tickets requiring a visit by field services. At Levels 5 and 6, automation will further reduce the amount of faults and troubles within Service Assurance. The improved prediction of future issues may call for some level of human interaction, but this will increasingly influence preventative maintenance activity, rather than fault resolution. As automation transforms the delivery of service assurance, service assurance in turn will play an essential role in supporting greater network automation. To fuel the analytics and intelligence required for intent-based automation, and enable closed-loop management, service assurance will need to increasingly support: Automated remediation through closer integration with fulfilment and orchestration systems Improved diagnostics and testing integration, allowing issues to be automatically diagnosed inform.tmforum.org SPONSORED FEATURE Greater context and visibility of complex network issues, supporting the resolution of the highly complex, highimpact issues that cannot be automated at medium levels of maturity (Levels 3–4) Improved support for fully machine-to-machine activity, rather than human-to-machine AI-driven processes to improve accuracy of service impact and root cause visibility in an active, software-based network where traditional methods are no longer applicable Greater governance and visibility of automation to mitigate the potential risks associated with reduced human involvement 32 While automation can drive value for CSPs across a broad range of technologies and processes, its impact on service assurance will be especially significant. Beyond its immediate utility for ensuring consistently high service quality and reliability, the automation of service assurance activities will remove friction from processes such as change management which can otherwise constrain the value of automation within the network. By helping to close the loops in closed-loop automation, a more mature and automated service assurance capability will help CSPs realize the benefits of intent-based automation as they evolve to a fully autonomous network.
