  1. All IP Reference Model focused on Radio Access Network 2000. 2. 17 ~18, San Diego Jaehong Park Ph.D. ,Yeonsang Koo, Inho You, parkjh@hei.co.kr, hwkoo@hei.co.kr, ihyou@hei.co.kr Hyundai Electronics Industry Co., Ltd. SC-AllIP-20000217-015

  2. Contents • Introduction • Approach scheme • Radio Access Network Reference Model I • Radio Access Network Reference Model II. • Radio Access Network Reference Model III • Architecture characteristics of each models • Summary SC-AllIP-20000217-015

  3. 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

  4. 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 SC-AllIP-20000217-015

  5. Radio Access Network Reference Model I Feature Server(s) AH Roaming G/W Legacy Network RMM Mobility Control Function HSS CCFA Vocoder PSTN Network Circuit G/W BTS PF Call Control Function Traffic Signal RRM Internet (Packet Network) Packet G/W Vocoder 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 SC-AllIP-20000217-015

  6. Radio Access Network Reference Model II AH Mobility Control Function Roaming G/W Legacy Network RMM RRM CCFA BTS HSS Vocoder Vocoder PSTN Network Circuit G/W PF AH BTS Feature Server(s) RRM RMM RAN Gateway Internet (Packet Network) Call Control Function Packet G/W CCFA RRM Radio Access Network BTS Traffic Signal IP Core Network • AH • Mobility Management • Call Control Function Agent • BTS • Radio Resource management • RAN Gateway • Packet Control Function • Provide bearer path • Optionally, vocoder in the case of using more than • one vocoding algorithm in the All IP Network SC-AllIP-20000217-015

  7. Radio Access Network Reference Model III BTS CCFA Call Control Function Roaming G/W Legacy Network RMM Mobility Control Function RRM Vocoder PSTN Network PF Circuit G/W DVF Feature Server(s) Vocoder BTS Internet (Packet Network) RAN Gateway Packet G/W HSS BTS Traffic Signal Direct Path (Signal& Data) Radio Access Network IP Core Network • DVF(DiVersity Function) • Frame Selection • RAN Gateway • Packet Control Function • BTS • Radio Resource management • Mobility Management • CCFA SC-AllIP-20000217-015

  8. Architecture Characteristic of each Models SC-AllIP-20000217-015

  9. 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 SC-AllIP-20000217-015
