2. Contents  Phase Approach  All IP Network Reference Model Phase I  All IP Network Reference Model Phase II  All IP Network Reference Model Phase III  All IP Network Reference Model Phase IV  Summary

3. Phase Approach Phase IV • MS can be seen in Internet • Change on air interface Phase III • BTS can be seen in Internet • Distribution of functionality of Core Network into Local Group Network Extension of IP node to MS Phase II • Integration of Voice and Data path • Separation Voice packet and Data Packet in the PDSN Extension of IP node from PDSN to BTS Phase I • Separation of Traffic into signal, voice and data • Use of IP transport within RAN and at A-interface Integration Voiceand Data path

4. All IP Network Reference Model Phase I FS Legacy Network Ater(A3+/7+) CSS RNCS A(A1+) SS7 G/W IP MCF IP CA MGC BTS SDU IP IP PSTN (A8/A9) Abis+ BP-GW HA PCF PSTN -GW IP (A10/11) Public Internet PDSN Packet G/W  Characteristics & Benefits • Separation of Signal, Circuit Voice and Packet Data • Utilizing of existing Air Interface with minor change • Distribution of functionality of legacy BSC and MSC • PDSN is at the boundary of IP network and wireless network • Minimization of changes on legacy structure • Support IP transport within RAN and at A-I/F

5. All IP Network Reference Model Phase II Legacy Network FS CSS Ater(A3+/7+) SS7 G/W RNCS IP IP A(A1+) CA MCF MGC BTS SDU+ IP PSTN Abis+ (A8/A9) HA PSTN -GW PCF+ PDSN+ (A10/11) Public Internet Packet G/W  Characteristics & Benefits • Integration of voice and data path which may result in some changes on the • functionality of SDU, PCF and PDSN • Others are same as Phase I

6. Function Entities in Phase I,II NRM  BTS  CA (Call Agent) • Radio Resource Management • Forward/Reverse Power Control • Call Processing • Call Control  MCF (Mobility Control Function)  RNCS(Radio access Network Control Server) • Handoff Control • Mobility Management (Authentication, Registration) • Call Control / Resource Management • Interworking with BTS and SDU • Communication with MCF using IOS Spec(based on IP)  MGC(Mediation G/W Controller ) • Control PSTN G/W and SS7 G/W  SDU  CSS(Common Subscribe Server) • Processing CDMA Traffic Channel Frame • Separation Voice and Data • Selection and Distribution of traffic channel frame (Soft H/O) • AAA • QoS Management • Mobility Management  PCF  PSTN G/W • Interface with SDU and PDSN for Packet Data Service • Handling Dormant functionality • Proving Voice/Data path with PSTN, ISDN and Cellular network • Vocoder  PDSN  SS7 G/W • Management Data packet and voice packet * • Signaling Interface with MCF * • Transporting Signaling with PSTN, ISDN and Cellular network • Vocoder  BP G/W (Bearer path Gateway) • Providing voice /data path • Trans-coding of voice data • Controlled by Call Agency  Packet G/W • Security, Fire wall

7. All IP Network Reference Model Phase III FS SS7 G/W LocalNetwork LAA Legacy Network MSS MGC RNCS BTS PSTN PSTN G/W LNG/W HA LNG/W Public Internet LocalNetwork PacketG/W  Characteristics & Benefits • BTS can be seen in Internet, which means every node except MS can be accessed through internet • For efficiency and load balancing • - Local Network (RAN ) is necessary - LN G/W for several protocol stack and accounting - RNCS contains call control functions. - LAA contains Authentication & Authorization • Keep the air interface as it was

8. Function Entities in Phase III NRM  LNG/W(Local Network Gateway)  BTS • Radio Resource Management • Maintenance PPP connection to MS • Mobility Management • Forward/Reverse Power Control • QoS • Accounting • interface with MSS • interface Node with Core Network  MSS( Main Subscriber Server)  RNCS(Radio access Network Control Server) • Management of all subscribers’ information • AAA • Call Control in local network • Communication with BTS & SDU  LAA(Local Authentication Authorization) • Authentication & Authorization at MS controlled local network

9. All IP Network Reference Model Phase IV Legacy Network All IP Service Provider Core Network PSTN Public Internet  Characteristics & Benefits • MScan be seen in Internet • Big Change on the air-interface • Ultimate Goal of All IP Network

10. Summary  Phase approach of All IP Network Reference Model  Separation of Signal, Voice and Data path respectively, in Phase I  Integration of Voice and Data path, in Phase II  In Phase III  Extension of IP node from PDSN to BTS - Requirement of new technique for Soft H/O  Distribution functionality of Core Network to local Network - Load Balancing - Efficient accounting - Support several protocol stacks  In Phase IV, MS can be seen in Internet - Big change on the air-interface
