▀ Configuring the System to Perform as a Standalone HSGW
Step 7
As part of the gateway control session establishment, the HSGW sends a CC-Request (CCR) message to the PCRF and
the PCRF acknowledges establishment by responding back with CC-Answer (CCA) message.
Step 8
HSGW uses the configured MAG context to determine the MAG service to use for the outgoing S2a connection.
Step 9 The HSGW establishes the S2a connection by sending a PMIP Proxy Binding Update (PBU) to the P-GW including the
NAI and APN. The PBU also includes the home network prefix and/or IPv4 home address option based on the
subscriber's APN profile and UE IP version capability.
Step 10
The P-GW responds with a Proxy Binding Acknowledgement (PBA) that includes the assigned IPv6 home network
prefix and interface identifier and/or IPv4 home address acknowledgement option based on the PBU.
Step 11
The HSGW conveys the assigned IP information to the UE in a VSNCP configuration acknowledgement message.
Additionally, if an IPv6 address is assign to the UE, the HSGW sends a router advertisement message to the UE
including the assigned home network prefix.
