  3. Primary Sites Vs Secondary Sites • Primary Site is the highest level site in the core network. • – Contains nodes, both controlling and switching nodes for CS and • PS respectively as well as BSC access nodes. • – MSC-S, M-MGw, SGSN, BSC nodes. • Secondary Site are sites with local switching capability and RAN • access. • – M-MGw and BSC nodes.

  4. Primary Sites Vs Secondary Sites

  5. Monolithic vs Layered Architecture

  6. Monolithic vs Layered Architecture MSC MSC-S MGW

  7. Migration from Monolithic to Layered architecture MSC Server MSC (Monolithic) GCP / SIGTRAN MGW Call Control Bearer

  8. Design Principle • Control Signaling between MSC-S and M-MGw is using SS7 over IP (SIGTRAN) • BSC is connected to one M-MGw only • Each monolithic MSC is connected to SGw over TDM • Signaling between Monolithic MSC and MSC-S will be via SGw.

  9. Design Principle BICC MSC-S MSC-S SIGTRAN MGW TDM MSC Monolithic MSC

  10. Transport Design Design Criteria: 􀂃 Up to 6 Node-Bs grouped into one cluster of a Sub-hub 􀂃 Up to 4 Sub-Hub clusters grouped into 1 hub. 􀂃 STM-1 from Hub/Sub-Hub to RNC through BSNL media Interfaces: 􀂃 End node-B: E1 interface. 􀂃 Sub-Hub: E1 interface / STM-1 interface. 􀂃 Hub: STM-1 interface.

  11. Hub- Sub-HUB Architecture

  12. Requirement from BSNL • 3E1 for Each Node B sites. • STM-1 between RNC and Hub RBS site • STM-1 between Hub RBS and Sub Hub RBS sites as • STM-1 between RNC and Core network. • Pool of IPs for O&M Purposes and GTPU Links (RNC to SGSN) – 16 IP per node-B – 64 IPs per RNC • 128 IPs for OSS • Separate IMSI series for USIM • STM from Every Circle to ViG

  13. Video Gateway (ViG) 􀂃 Video Gateway (ViG) interconnects WCDMA core network on one side and an IP network on other. It supports, IP-based Video Messaging systems and Multiparty Conferencing Systems 􀂃 Proposed ViG offers following services: – Mobile to Mobile Video Calls – Mobile to IP client (PC) video calls. – Circuit Switched Streaming – Multi-party Video Conferencing

  14. ViG: Basic Connectivity • Used for Mobile to PC and PC to Mobile Video Calls • Video Conferencing

  15. Key Services being offered • 􀂃 Mobile to Mobile Video Call • 􀂃 Mobile Broadband (High Speed Data) • 􀂃 Video Streaming (Clips/Movies etc.) • 􀂃 Mobile TV (Live TV Channels)
