What information is exchanged between (signalling / user data) 1. MBMS GW & MME 2. MBMSGW & BMSC
I know one MCCH channel is associated to one MBSFNArea Configuration and MBSFNAreaConfiguration carries the configuration associated to a particular MBSFNArea. I have no idea of use of SC-MCCH logical channel. Can a cell support both logical channels simultaneously ? If both can exist together in a cell then UE will choose which channel ? Can someone please share his/her thoughts over these queries ? Thanks in advance.
I found that PGW connects with BMSC and Content provider by using SGi interface. Can anyone please help me to understand what is the purpose behind having SGi ?
PGW is connected with AAA server with 2 interface . 1. SGI interface 2. S6b interface.
Why SGI is required if s6b is already there?
