How MME will identify that the session is S mode or P mode ? who will decide this ? Is it depend on APN [from HSS] name ?
Ex,
If it is S mode the MME will forward it to SGW or it will forward to PGW right. So how this decision will be taken at MME ?
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 ?
I am new for LTE technology. Please help me to get understand the role of MME in LTE technology?
