  5. Service Platforms and Interworking of Services Definitions • Service Convergence:From the user’s perspective, services operate in a sufficiently similar manner (minimal or no perception of changes when accessing from different service providers, through different devices or different access technologies). • Service Continuity: From the user’s perspective, services operate in a sufficiently similar manner (minimal or no perception of changes) as the user moves the active service between access technologies and devices. • Service Delivery Platform:An architecture that enables the rapid development, deployment and integration (convergence) of broadband, video, wireless and wireline services. An SDP can support many technologies including VoIP, Mobile Telephony, IPTV, HSD (High Speed Data), Online Gaming, etc. GSC: Standardization Advancing Global Communications

  10. Service Platforms and Interworking of Services ATIS NGN Framework – Gap AnalysisAssessment of NGN service enablers; progress of NGN standards development(GSC11_GTSC4_22) • Service Decoupling - enables services to be defined and delivered independent of a specific "vertical” network function; enables a flexible service environment, including third party services • Gaps: application/end user access to service capabilities, resource control • Service Transparency - enables services to evolve independent of the network • Gaps: service interworking with non-NGN, maintain Internet end-to-end transparency (NATs, Firewalls) in NGN • Unified User Profile - enables service capabilities to be accessed from a range of devices and locations • Gaps: Web Services, IPTV GSC: Standardization Advancing Global Communications

Open Service Access (OSA) has been developed as part of the 3GPP specifications in coordination with ETSI and Parlay (and liaisons with 3GPP2, OMA, and others). The Parlay Group is a multi-vendor consortium formed to develop open, technology-independent APIs that enable the development of applications that operate across multiple networking environments. Applications are independent of underlying network technologies and can be hosted inside or outside Network Operator Domain Parlay defines standardized interfaces as specifications - Service Capability Features (SCF) One or more SCF’s are implemented as Service Capability Servers (SCS) and are –provided by Network Vendors as a Parlay/OSA Gateway The SCS implementation maps the Parlay interface to the network protocol/interface GSC: Standardization Advancing Global Communications

  14. Service Platforms and Interworking of Services Work on ConvergenceATIS Packet Technologies and Systems Committee (PTSC) • PTSC Issue S0044 • Service Continuity Between Access Networks • Work has just started on an aggressive schedule • As Next Generation Networks (NGNs) evolve and are deployed, there will be an increasing need to provide continuity of service as the subscriber transitions from one access network to another • Must have a consistent user perspective • Service delivery needs to be access independent • Not Just Voice but Multimedia GSC: Standardization Advancing Global Communications

  15. Service Platforms and Interworking of Services Work on ConvergenceATIS Wireless Technologies and Systems Committee (WTSC) • WTSC Issue P0012 • Voice Call Continuity (VCC) • seamless continuity for voice calls that move between the two types of networks (between cellular networks and non-cellular networks (e.g., wireless LAN networks)) • Contributions to ongoing work in 3GPP GSC: Standardization Advancing Global Communications

  16. Service Platforms and Interworking of Services Summary • Service convergence is a major focus in the Next Generation Networks vision • NGN Service Architecture enables service transparency across networks and secure access to new and innovative applications • NGN service architecture supports converged text, voice, data, video, and multimedia services • Work needs to continue to address gaps in standards required to realize true service interworking Service Architecture and Interworking standards are evolving to address the requirements of the NGN vision GSC: Standardization Advancing Global Communications
