  2. Contents  Phased 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. Phased Approach Phase IV • MS can be seen in Internet • Changes on air interface Phase III • BTS can be seen in Internet • Distribute Core Network Functionality to Local Group Network Move IP node to MS Phase II • Integrate Voice and Data path • Separate Voice and Data Packet at the PDSN Move IP node from PDSN to BTS Phase I • Separate Traffic into signal, voice and data • Use IP in RAN and A-interface (for transport protocol) Integration Voiceand Data path

  4. All IP Network Reference Model Phase I FS Legacy Network A3/7 CSS RNCS 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 • Separate Signal, Circuit Voice and Packet Data • Distribute BSC and MSC functionality in the legacy network • PDSN locates at the boundary of IP network and wireless access network • Minimizes changes on the legacy network structure • Support IP in RAN and A-I/F

  5. All IP Network Reference Model Phase II Legacy Network FS CSS A3/7 SS7 G/W RNCS IP IP 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 • Integrate voice and data path and it causes some changes on the • functionality of SDU, PCF and PDSN • The others are same as Phase I reference model

  6. Function Entities in Phase I,II NRM  RNCS(Radio access Network Control Server)  CA (Call Agent) • Call Control / Resource Management • Interworking with BTS and SDU • Communicate with MCF using IOS (based on IP) • Call Control  MCF (Mobility Control Function) • Handoff Control • Mobility Management (Authentication, Registration)  SDU • CDMA Traffic Channel Frame processing • Voice and Data separation (only Phase I) • Selection and Distribution of traffic channel frame (Soft H/O)  MGC(Mediation G/W Controller ) • Control PSTN G/W and SS7 G/W  CSS(Common Subscribe Server)  PCF • AAA • QoS Management • Mobility Management • Interface between SDU and PDSN for Packet Data Service • Dormant functionality handling  PDSN  PSTN G/W • Management Data and voice packet * • Signaling Interface with MCF * • Provides Voice and data path with PSTN, ISDN and legacy network • vocoder  BP G/W (Bearer path Gateway) • Provide voice /data path • Trans-coding of voice data • Controlled by Call Agency  SS7 G/W • Transport signaling data to/from PSTN, ISDN and legacy network  Packet G/W * Phase II Model • 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  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  Phased approach of All IP Network Reference Model  Separate Signal, Voice and Data path respectively, in Phase I  Integration of Voice and Data path, in Phase II  In Phase III  Move IP node from PDSN to BTS - Requirement of new technique for Soft H/O  Distribute Core Network functionality 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
