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.

LTE: Why does SGW include S5/S8 interface PGW-C F-TEID in Create Session Response message to MME ?

I want to know what MME does with these PGW-C and PGW-U tunnel Ids ?
