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

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 (e-mail, 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

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
