All IP Network Reference Model 2000

This reference model outlines the phased approach for an All IP Network implementation, integrating voice and data paths with legacy networks while ensuring efficient functionality and support. The model includes Phase I to Phase IV transitions, highlighting changes in network structure, integration of IP nodes, and benefits of IP transport within the network.

  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
