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 ?

Hi as PGW is for packet gateway, so an interface is required between MSC, RNC, SGSN, GGSN to PDN.

As per LTE core network architecture, MME shares S11 interface with SGW and SGW has S5/S8 interface with PGW.
I went through Create Session Response message sent by SGW to MME and found PGW-C and PGW-U tunnel ids.
I want to know what MME does with these PGW-C and PGW-U tunnel Ids ?
