I could not understood the question, but I assume that you are asking for the call flow of LIPA/SIPTO PDP Context creation/activation. Here is the basic call flow (Ref 3GPP 23.859)
Is there any information sent by UE to MME in Attach Request so that MME can find out the necessity of LIPA PDN connectivity ?
I have one doubt over S5 interface. Interface between SGW and PGW in lte core known as S5 interface. Now I found again S5 interface between L-GW( which is co-located with HeNB ) and SGW of core network. Can someone please explain why this interface is required ?
I am looking for a complete call flow to setup a bearer in lte network including Local IP access(LIPA). Thanks in advance.
