Proxy Mobile IPv6 (S2a)
Provides a mobility management protocol to enable a single LTE-EPC core network to provide the call anchor point for
user sessions as the subscriber roams between native EUTRAN and non-native e-HRPD access networks
S2a represents the trusted non-3GPP interface between the LTE-EPC core network and the evolved HRPD network
anchored on the HSGW. In the e-HRPD network, network-based mobility provides mobility for IPv6 nodes without
host involvement. Proxy Mobile IPv6 extends Mobile IPv6 signaling messages and reuses the HA function (now known
as LMA) on PDN Gateway. This approach does not require the mobile node to be involved in the exchange of signaling
messages between itself and the Home Agent. A proxy mobility agent (MAG function on HSGW) in the network
performs the signaling with the home agent and does the mobility management on behalf of the mobile node attached to
the network
The S2a interface uses IPv6 for both control and data. During the PDN connection establishment procedures the PDN
Gateway allocates the IPv6 Home Network Prefix (HNP) via Proxy Mobile IPv6 signaling to the HSGW. The HSGW
