TIA TR-50 Scope
(Chair: Jeffrey Smith, Numerex; Vice Chair: Jim Wert, ILS Technology)
•
Engineering Committee TR-50 Smart Device Communications is responsible
for the development and maintenance of access agnostic interface standards
for the monitoring and bi-directional communication of events and information
between smart devices and other devices, applications or networks.
•
TR-50 will develop a Smart Device Communications framework that can
operate over different underlying transport networks (wireless, wired, etc.) and
can be adapted to a given transport network by means of an
adaptation/convergence layer.
•
The TR-50 framework will make its functionality available to applications
through a well-defined Application Programming Interface (API) that is agnostic
to the vertical application domain (eHealth, Smart Grid, Industrial Automation,
etc.)

TIA TR-50.1 Scope
GSC16-PLEN-41
Requirements and Architecture
(Chair: Peter Nurse, Sigma Delta; Vice Chair: Mitch Tseng, Huawei)
•
Requirements shall be agnostic to the application (e.g. eHealth, Smart Grid,
Industrial Automation, etc.), but shall reflect the requirements of the
applications of interest. Examples of such publications include Use Cases and
Stage-1 Descriptions.
•
System architecture shall be agnostic to the application, but shall reflect the
requirements of the applications of interest, including their information models.
•
Data models requirements shall be agnostic to the application, but shall reflect
the requirements of the applications of interest.
•
In its work, Subcommittee TR-50.1 shall take account of the following: Security
(e.g., data content, authentication, signaling); End to End Performance and
scalability of equipment and networks; and Device Management (incl.
discovery and identity)

TR 50 Security Ad Hoc Scope
(Chair: Chuck Bokath, Georgia Tech Research Institute; Vice Chair Mihai Voicu: ILS Technology )
 The scope of work within TR-50 SDC Security Ad Hoc includes the following:
Participate with TR-50 and its other subcommittees to contribute requirements, architecture,
protocols, etc. related to the topic of security in Smart Device Communications.
Review and approve all ballots by TR-50 and its subcommittees to ensure that any
architectures, protocols, or specifications meet the requirements set by the SDCSS for a
secure solution.
 Additional directives to be followed by the TR-50 SDCSG:
The architecture, protocol, or specification should support options that can be exported
without undue overhead from countries for which TIA serves as a regional Standards
Development Organization (SDO).
 Guidelines include the Cryptographic Interoperability Strategy that uses a multi layer
approach enabling multiple zone security while data is in transit, security profiles to best “fit”
each class of device, secured sharing suite that utilizes common standards, protocols and
cipher algorithms, threat analysis and metrics to assess security issues and the creation of a
security test bed for private and commercial use

GSC16-PLEN-41
Update (1)
• SDC Standards in final stage of publication
– Provide a reference architecture, describing functional elements
and their interconnection.
– Provide identified use cases and demonstrate the applicability of
the reference architecture to the support of those use cases.
– Ballot Resolution in October; Publication in December, 2011.
– SDC Protocol Stack unchanged from GSC-15

Update (2)
• Introduce SDC High-Level System Architecture
– Introduce “Containers” concept to better describing functional
elements and their logical interconnections.
• Will continue work on “Convergence Layer”
and harmonize with other standard entities.

of the architecture
 Data In Transit (Phase 2 of 2)
 Multilayer Security
 Finishing Security Zone Definitions
 Data At Rest (Phase 1 of 2)
 Trusted Environments
 Draft Phase
 Threat Analysis (Phase 2 of 2)

 GT M2M Testbed (Phase 1 of 3)
 Assess selected M2M systems to identify cyber vulnerabilities. Testing is planned and conducted in collaboration
with the interested industry partner and may be performed in the laboratory (test bed) environment or at the
partner's site.
 Provide M2M Security training through workshops that describe common cyber vulnerabilities found in M2M
systems and effective methods for mitigation.
 Share with appropriate standard's organizations information that can be used to support the development of
improved industry standards applicable to control system security.
 Participate in conferences that include M2M security topics to share information obtained through system
assessments and analyses.

Highlight of Current M2M
Activities In TIA TR-45 Mobile and Personal
Communications Systems
• TR-45 M2M work is developed in partnership with 3GPP2
• M2M communication carried over cdma2000 1x or HRPD networks
• cdma2000 role is largely confined to serve as a transport network,
providing services to external M2M entities (M2M service layers
and M2M applications)
• M2M services may have their own specific characteristics which
might be different from services in which humans directly influence
communication flow. This may require some special handling or
optimization on cdma2000 network for better support of M2M
communications
• Some of the M2M requirements apply to both M2M and H2H
(Human-to-Human) devices

M2M Numbering and Addressing for
cdma2000 Networks
• Analyzing issues associated with M2M Numbering,
Identification and Addressing aspects of M2M
technologies and services using TIA specifications,
including:
– M2M numbering and addressing schemes
– Investigation of Global M2M numbering issues with
liaison with industry M2M committees and
stakeholders
– Evaluation of M2M numbering resources/methods
and identifying impacts on legacy numbering and
back office systems
• Planned publication as TIA-4962 (3GPP2 SC.R4005-0)
in 4Q2011

M2M Systems Requirements for
cdma2000 Networks
• System requirements for M2M communication using
cdma2000 1x and HRPD are in development
• The specification will guide the work of the enhancements
required to the cdma2000 technology for the support of
M2M communication. The intent is to provide guidance to
which areas could require improvements and also to
understand potential external coordination with other
industry forums to assist in the development of the overall
solution for M2M
 Planned publication as TIA-4954 (3GPP2 S.R0146) in
2Q2012

Next Steps for cdma2000 Networks
• Prioritize the key use cases and solutions
– Operator needs
– Vendor needs
• Development of the appropriate specifications
– New specification and/or new versions of existing documents as
required
– Completion for phase 1 specifications is to be determined
• Continue work on the M2M Communication Systems
Requirements for future phases.
– M2M landscape is evolving
•
Continue work on the next set of use cases and solutions as
part of the M2M Architecture and Enhancement Study for
