If a APN is SIPTO enabled, MME has to select the geographically closer GWs during GW selection and continue to do so during UE Mobility. My question is what are the parameters of DNS query and what is the actual syntax of that query ?
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 ?
Can anyone please explain SIPTO functionality for lte network ?
