What is CSN?
n
n
n
Converged Service Network (CSN) studies functional
requirements to provide a guideline for telecom network
operators, equipment providers, application providers,
software developers, content providers to build a
comprehensive echo-system for all the stakeholders in value
chain.
CSN provides an open environment in NGN, which offers
support for a diverse group of application developers and
service providers to integrate the capabilities from different
domains (e.g. Telecom (Fixed and Mobile Networks),
Internet, Broadcasting etc.) over NGN.
NOTE: CCSA TR.CSN is aligned with NGN-SIDE being
studied in ITU-T Q3/SG13.

Strategic Direction (1)
CSN puts operator in the center to control the whole value chain and opens
numerous revenue opportunities for operator on connecting end-users with 3rd
party services, and getting paid by the 3rd party for doing so.

Challenges
§ Strong coordination is needed among SDOs
involved in the development of different aspects of
service delivery platform;
§ Collective effort is needed to identify the minimum
set of standardized APIs to be adopted by a
service delivery platform;
§ Interoperability among different service delivery
platform implementations.
8
Next Step:Support for Cloud Computing(1)
CSN supports different cloud computing service provisioning models such
as Software as a Service (SaaS), Platform as a Service (PaaS), and
Infrastructure as a Service (IaaS).
9
Next Steps: Support for UN (2)
CSN is currently investigating impacts of Ubiquitous Network (UN)
applications such as M2M applications on service delivery platform. Major
considerations are adaptors and integration aspects.

Service creation environment (SCE)
CSN supports multi-SCE to meet diverse market needs.
§
Standard SCE: suitable for
the services which require
complicated function, high
capability and large scale
application.
§
WEB service SCE:
Suitable for the third parties
who have normal
developing team.
§
GUI SCE: GUI, drag-anddrop, suitable for the 3rd
with small-scale developing
team.
§
“0” coding SCE: To
enable the ordinary users
to utilize this tool to develop
their own service.

Context handling in CSN
Supports mechanisms for context management from the
following aspects:
§
context information such as QoS, connectivity, communication
capabilities, location, presence, service type about context entities and
context access such as register, query, subscribe, notify, update, etc.

Adaptation concept in CSN
n
In CSN, adaptation consists of a) service brokering,
and b) adaptors functions as follows:
Service brokering function:
§
§
n
performs interaction between applications and
capabilities for the downward invocation of capabilities;
handles triggering of events from NGN or Non-NGN
towards applications.
Adaptor function:
§
§
performs network exposition to access capabilities from
underlying networks;
performs protocol conversion to shield the complexities of
protocols and keep a horizontal service integration
25
architecture.
Adaptors in CSN
n
In CSN, adaptors are categorized as a) adaptors for
NGN, and b) adaptors for Non-NGN:
Adaptors for NGN include:
§
§
n
Adaptors for NGN capabilities including service
enablers;
Adaptors for NGN resource (i.e. connections,
computing, storage).
Adaptors for Non-NGN include:
§

§
Adaptors for legacy network including PSTN & PLMN;
Adaptors for internet;
Adaptors for content delivery network (CDN);
26
Adaptors for Ubiquitous Networking (UN).

3rd party application scenario
This scenario describes how CSN facilitates 3rd party
applications, for example “Book a trip” to access capabilities
from other domains (i.e. Telecom and Internet).
28
In-house application scenario
This scenario describes how CSN facilitates SP hosted applications, for
example, “Enhanced Conference” to access capabilities from other domains
(i.e. Telecom and IPTV).
