S2a Interface
This reference point supports the bearer interface by providing signaling and mobility support between a trusted non-
3GPP access point (HSGW) and the PDN Gateway. It is based on Proxy Mobile IP but also supports Client Mobile IPv4
FA mode which allows connectivity to trusted non-3GPP IP access points that do not support PMIP.
