HSGW
In support of both mobile and network originated subscriber PDP contexts, the HSGW provides the following network
interfaces:
interfaces:
A10/A11
This interface exists between the Evolved Access Network/Evolved Packet Control
Function (eAN/ePCF) and the HSGW and implements the A10 (signaling) and A11 (bearer) protocols defined in
3GPP2 specifications.

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.
