8 TSG-S PMT Evolution Workshop – Seoul, Korea Page 7 Vision Document - Overview Steering Committee Library Document SC.R5001  The objective: Capture long-term vision beyond what is described in the current Release Plan and Evolution document  Guidance to 3GPP2 regarding new capabilities/features on which to focus in further development plans  Work in progress, as work plan moves forward  Ultimately market needs drive the wireless network evolution  SC.R5001 provides a structure to the process by outlining trends Continuation of cdma2000’s evolution  Delivering value-added applications/services to the user  Seamless mobility  Portability  Location information  Emphasis on backward compatibility for the cdma2000 Radio family of interfaces  Compatibility and interoperability with existing and emerging wireless/mobile technologies

9 TSG-S PMT Evolution Workshop – Seoul, Korea Page 8 Vision Document - General Continuation of cdma2000’s evolution  Delivering value-added applications/services to the user  Seamless mobility  Portability  Location information  Emphasis on backward compatibility for the cdma2000 Radio family of interfaces  Compatibility and interoperability with existing and emerging wireless/mobile technologies

10 TSG-S PMT Evolution Workshop – Seoul, Korea Page 9 Vision Document – Key Enablers Applications – Vision Going Forward  Diversity of applications independent of access network – successful applications must be easily portable between access networks  Collaborative posture with: 3GPP, OMA, IETF, ITU-T NGN  Asymmetric applications (BCMCS, Web-browsing) allow network throughput commensurate with inherent radio resources  Flexible network services compatible with both models: Wireless Network Operator (WNO) hosted; managed by external providers (aggregators, resellers, IT application developers).  Standards-based service architecture: Parlay/OSA.  Web services technologies based on SOAP/XML/HTTP as they mature  Execution policy and workflow concepts support flexible service control at network service invocation  Continue to work in concert with OMA, W3C, OASIS, etc., on network services enabling technologies and architectures

11 TSG-S PMT Evolution Workshop – Seoul, Korea Page 10 Vision Document – Key Enablers Location Services – Build on Success  Uniquely suitable to wireless communication  Some of the forthcoming applications include: network optimization; predictive traffic loading; commercial services (e.g. fleet management)  Utility expected to increase for IP-based location services over faster access technologies (cdma2000 EV-DO), e.g. for fast map download  Economy and accessibility expected to be enhanced by managing assistance delivery and controlling location reporting  [Ample illustrations to be provided later]

12 TSG-S PMT Evolution Workshop – Seoul, Korea Page 11 Vision Document – Key Enablers Security – Key Service Enabler  Access Security – ensuring only authentic subscribers can gain access  End-to-End Service Security – ensuring only authorized subscribers can use specific service, particularly important in IP era  Systems must provide privacy to match user expectations  While protecting the network, operators must provide transparency for user specific protection mechanisms (e.g. VPN)  Since Internet applications ( , web browsing, multimedia streaming, etc.) proliferate in mobile environment, threats are similar to those in the wired Internet  Traditional access security may be supplemented by user/terminal validation (voice, fingerprint, iris, …)  Seamless roaming across administrative domains (e.g. WLAN roaming) is of increasing importance

13 TSG-S PMT Evolution Workshop – Seoul, Korea Page 12 Vision Document – Key Enablers Application Level Security Aspects  Certificate Based Security (subscriber-based and server-based) is required for m-commerce and m-transactions  Contents Rights Protection (e.g. DRM) - copyright protection of content such as music or video increasingly available in mobile environment  End-to-End (application layer) security (authentication, privacy and integrity) require transparency of network architecture and underlining transport mechanisms  Short range Interface Security (e.g. IrDA and Bluetooth)  Spamming is of magnified concern over the expensive radio link  Similar concern exists for Denial of Services (DoS) attacks or Distributed Denial of Services (DDoS) attacks, packet spoofing  3GPP2 is well on the path to improve network robustness against these kinds of attacks

14 TSG-S PMT Evolution Workshop – Seoul, Korea Page 13 Vision Document – Key Enablers Network and Service Management  [To be Elaborated]

15 TSG-S PMT Evolution Workshop – Seoul, Korea Page 14 Vision Document – Key Enablers Quality of Service (QoS)  Aspect One: Ability to cope with service attributes of different applications (e.g. low-delay RTP vs. delay-tolerant web browsing)  Aspect Two: Ability to distinguish between tiers of users based on willingness to pay  Essential for cost-effective radio network for high-speed data services  Solutions should address a continuum of delay variations and other QoS attributes expected in future wireless applications, e.g. Real-Time, Wireless Interactive Gaming, Premium Web Access, … down to Best Effort

16 TSG-S PMT Evolution Workshop – Seoul, Korea Page 15 Vision Document – Technology Enablers Advanced Antennas, such as MIMO Software Defined Radio (SDR)  Upgrade radio software remotely and wirelessly (e.g. application software version upgrades, air interface protocol stack)  Reconfigure radio dynamically for access technology in locale  Realization of common terminal platforms across multiple access technologies or performance/capability tiers  Develop common wireless access device platforms (e.g., base stations) IP Core Network Research  Further MMD network evolution Physical/MAC Layer Research Codec Research

17 TSG-S PMT Evolution Workshop – Seoul, Korea Page 16 Vision Doc – Wireless IP RAN Architectures Vision Document anticipates several areas of research:  New techniques for discovery of network/service resources  Distributed resource techniques and optimum distribution of network/service resources  Policy-based network resource allocation and QoS control  Distributed mobility management techniques  Operational research allowing planning to meet complex and non- uniform performance goal
