This Study item is to study:
The addition of a S2a based on GTP option. In particular this SID will develop the necessary stage 2 message
flows to support S2a based on GTP and mobility between GTP-S5/S8 and GTP-S2a.
Supporting WLAN access to EPC through S2a via mechanisms:
with no impact to the UE;
with impact to the UE.
Solutions requiring modifications to non 3GPP link-layers will not be considered. It is expected that the result of this
