Role of Q25/13 • Complex systems (such as NGN, IPTV) need robust program management • Q25 provides program management tool, and maintains ‘Road Map’ documents • Industry needs common language and unique terms for each concept, architectural element, protocol definition, etc. in order to guard against misunderstanding and confusion • Q25 collects, revises and publishes all relevant terms and definitions (related to NGN and future networks) in a dedicated ITU-T Recommendation
Q.10 (Identification of Evolving IMT-2000 Systems and Beyond)
Role of Q10/13 • IMT is perhaps the most recognized initiative spanning all three Sectors of ITU • IMT is developed by a number of globally recognized SDOs (at 3GPP and 3GPP2) • Q10/13 facilitates the recognition of these systems, and their adoption by the broader ITU community • Q10/13 produces Recommendations for IMT family members based on (1) GSM-evolved core with UTRAN/GERAN access, and (2) ANSI-41 evolved core with CDMA2000 access
Q.15 (Applying IMS and IMT in Developing Country Mobile Telecom Networks)
Role of Q15/13 • There is a need to study requirements of telecom networks in developing countries with the increasing shift towards mobility and convergence • The work needs to be done in close cooperation between all three Sectors of ITU and relevant external organizations • Q15/13 develops scenarios and requirements, in terms of services and deployments, for applying IMT and IMS to mobile networks in developing countries

WP2 in SG 13 Classifications of Questions Overall Future Requirements WP2 Q 3, 12, 24 Architectures Q 5, 9, 22 QoS and Security Q 4, 16, 17 Q 10, 15, 25 & ITU-D, Mobile (3GPP) Q 7, 19, 20, 21
Role of Q.3/13 • Motivation • Key requirements to be considered are ubiquitous support of: seamless end-to-end service operations, service access by mobile and wireline users, wireless/wireline technology independent service access, real time multimedia content delivery, unicast and multicast delivery technologies, SLAs and differentiated levels of quality of service, enhanced security, service mobility, service interworking, policy based capabilities, context based capabilities, user identification, authentication and authorization, service discovery, service routing, service brokering, service composition, and both IPv4 and IPv6 protocol technologies. • Emerging services include IP multimedia telephony applications, IPTV applications, content delivery services, business/enterprise communications, ubiquitous sensor network based applications, identification based services, context aware services, third party services such as managed delivery services and others, applications of user networks (home networks), applications of grids and related enablers, VPNs and other network virtualization applications, managed peer to peer services, advanced data communication services, as well as other future applications and services based on composition of open service environment capabilities.
Role of Q.3/13 • Tasks • Development of Recommendations on emerging services in evolving next generation multi service network environments (requirements and capabilities, service and network architectures, implementation scenarios). • Development of Recommendations on open service environment and SOA in evolving next generation multi-service network environments (including requirements for telecom SOA and telecom APIs, and capabilities and components of a SOA enabled open service environment). • Completion of draft Recommendations currently under way. • Revision of Y.2233 • Maintenance and enhancement of the Recommendations for which the Question is responsible. • Coordination with the NGN related Questions (in particular in the areas of NGN services and architectures). • Coordination with standardization bodies, fora and consortia involved in standardization of SOA and application to network interface related aspects.
Role of Q.12/13 • Motivation • The rapid growth and the embedded base of legacy telecommunications networks have necessitated a strategy of evolution towards integrated multi-service networks which connect to enterprise and home networks. Due to popularity of the IPTV and transformation of networks to NGN it has become necessary to include study of home networks. Thus the focus of this Question will include activities related to IP television (IPTV) and home networks. This Question will address items such as: • determination of how best to carry narrow-band and broadband services of a fully integrated IP-based network across non-IP based networks (e.g. FR and ATM); • description of interworking of services, including definition of protocol requirements; • interworking of services between home network operator administered networks.
Role of Q.12/13 • Tasks • Creation of, maintenance and enhancement to the Recommendations in Y.1400 series • Maintenance of Recommendations Y.2261, Y.2262 and Y.2271 • Maintenance and enhancement to the Recommendations in I.500 series • Maintenance and enhancement to Recommendations Q.933, Q.933bis, X.36, X.76, X.84, X.142, X.144, X.145, X.146, X.147, X.148, X.149, X.151 and X.272 and the development of new Recommendations as deemed necessary • Completion of draft Recommendations already under discussion in Questions 12/13 • Development of new Recommendations related to home network and their interworking aspects with the operator administered networks • Development of new Recommendations related to interworking to support IPTV services
Documents in Q12/13 • Recommendations • Documents under study
Role of Q.24/13 Motivation As NGN and Future Networks scope covers wide areas of network, a set of promising service scenarios and deployment models of NGN and Future Networks are very useful to accelerate the NGN and Future Networks deployment. All the scenarios should be initiated from the user point of views, which would be described as use cases. At the same time, operators of existing telecommunication networks have expressed concerns connected with the necessity of full replacement of their network equipment when migrating from traditional telecommunication networks to NGN and Future Networks. For Future Networks, more and more new technologies will be introduced, e.g. Cloud Computing, IoT, etc. The architecture and deployment of Future Networks will be probably largely different from the existing telecommunication networks. Foregoing requirements will be still available when existing telecommunication networks or NGN migrate to Future Networks.
Role of Q.24/13 • Tasks • Develop documents on NGN and Future Networks service scenarios including emerging services and converged services. • Develop documents on NGN and Future Networks based IPTV service scenarios that converge traditional broadcasting services and telecommunication services over the NGN and Future Networks environment. • Develop documents on service scenarios of use cases and 3rd party services for ubiquitous environments. • Develop documents on migration scenarios to NGN and Future Networks. • Develop documents on decision factors for selecting migration scenarios and migration criteria through analysis of the scenarios. • Continue documents currently under way. • Documents produced under this Question will normally be published as Supplements or will progress through, or in coordination with, other related Questions.
