Description

In order to support GSM-R ASCI, we'd need VGCS/VBS support.

In the BSC, this mostly means the following:
  • definition of VBS/VGCS areas e.g. via VTY (or simply assume all areas are global in initial implementation)
  • Abis: generation of RSL NOTIFICATION messages
  • A interface / BSSMAP
    • VGCS/VBS SETUP + VGCS/VBS SETUP ACK + VGCS/VBS SETUP REFUSE messages
    • VGCS/VBS ASSIGNMENT REQ
    • UPLINK REQUEST, UPLINK RELEASE NOTIFICATION, UPLINK SEIZED COMMAND, UPLINK REQUEST ACK, UPLINK REJECT
    • VGCS ADDITIONAL INFORMATION
There's quite a bit of state machines and logic required.
  • VGCS/VBS setup procedure
  • VCGS/VBBS assignment proceure
    • procedures according to TS 48.008 section 3.1.21, 3.1.22
  • handling of uplink related allocation and release procedures (VGCS)
  • periodic NCH transmissions
  • SACCH indications of NCH changes
  • managing the bsc-colocated osmo-mgw
    • allocate a 'broadcast' endpoint with one sender and many recipients
    • RTP connections for each BTS
    • RTP connection to the MSC
    • modifying rcvonly/sendonly/sendrecv according to current talker setate (VGCS)
