FA and HA Function for 3GPP-WiMAX Interworking at HA
The FA and PMIP4 client provides following functionality to support 3GPP2-WiMax Interworking at HA:
For WiMAX access, the PMIP4 client must not include the MN-AAA AE in the RRQ.
For 3GPP2 access, the FA must not remove the MN-AAA AE from the RRQ. This requirement stands even if
the CDMA2000 AAA sends the MN-AAA Removal Indication VSA with its value set.
The HA provides the following functionality to support 3GPP2-WiMax Interworking at the HA:
The HA recognizes the difference between 3GPP2 and WiMAX access technologies based on the presence or
absence of MN-FA and MN-AAA AE. If the MN-FA and MN-AAA are present in the RRQ, the HA assumes
that the RRQ is coming through a 3GPP2 network. Otherwise, the HA assumes that the RRQ is coming
through a WiMAX network.
that the RRQ is coming through a 3GPP2 network. Otherwise, the HA assumes that the RRQ is coming
through a WiMAX network.
The HA updates mobility bindings for different access technology types while maintaining binding integrity.
(Binding continues to be active until updated).
The same HA is able to handle packets from the MS with a given Care-of Address when the mobility binding is
pointing to a different Care-of Address. This is to mitigate packet loss in the uplink during seamless mobility
across access technologies.
across access technologies.
Before configuring the 3GPP-WiMAX Interworking, consider the following:
Generic Configuration:
Separate FA service is used for 3GPP2 and WiMax network.
The subscriber must be authorized to use PMIP for WiMax access.
The subscriber must use CMIP to access 3GPP2 network and must not set the s-bit in the RRQ.
WiMAX FA Service Configuration
MIP key from AAA must not be suppressed with the
command.
Revocation must be enabled
