 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

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

 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

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

 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

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
