Introduction

  • Most Contributions in All IP NRM have been focused on Core Network

  • The necessity of investigating Radio Access Network Model in All IP

  • RAN reference Model regardless of Core Network

  • Considering All IP RAN Reference Model utilizing legacy functions.

  • Developing necessary functionality to support the All IP RAN Reference

    Model

SC-AllIP-20000217-015


Approach Scheme

Assumption

  • BSC is removed

  • BTS is IP node

Identificationof necessary functionality

  • Call Control

  • Radio Resource Management

  • Mobility Management

  • Packet Control Functions

Identification of the relationships among the functionality

Verification using important scenario flow

  • Voice Data Traffic

  • Mobility management Signal

  • Packet Data Traffic

  • Call Control Signal

  • etc.

  • Radio Resource Assignment Signal

Allocation of functionality to physical node

IP Core Network

  • AH(Access Handler)

  • Same as BSC except for the absence of SDU

  • SDU moves to Circuit G/W connected to PSTN

  • Function of AH

- Radio Resource management

- Packet Control Function

- CCFA

- Mobility Management

- Etc (ex: address conversion …)

  • CCFA(Call Control Function Agent)

  • Collecting resource status through communicating with RRM & Reporting to CCF

  • cdma2000 Message transform

Summary

 Focused on RAN Model in all IP NRM

 Propose an approach scheme for RAN Reference Model

 Propose the threeRAN Reference Model in All IP NRM

 Propose several ideas through the Reference Model

- Removal of BSC

- Distribution functionality to BTS’s.

- Location of Vocoder

- Introduction of DVF

- Function of CCFA

- Identification of RAN G/W
