eHRPD
In support of both mobile and network originated subscriber PDP contexts, the HSGW provides the following network
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.
eAN/ePCF
A10
L1/L2
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.
