WiMAX-3GPP2 Interworking at HA
The session continuity capability enables a dual mode device (a multi radio device) to continue its active data session as
it changes its active network attachment from 3GPP2 to Wimax and vice versa with no perceived user impacts from a
user experience perspective.
it changes its active network attachment from 3GPP2 to Wimax and vice versa with no perceived user impacts from a
user experience perspective.
This capability provides the following benefits:
common billing and customer care
accessing home 3GPP2 service through Wimax network and vice versa
better user experience with seamless session continuity
To provide this capability, the HA supports seamless handoff from 3GPP2 to WIMAX and vice versa.
This section describes the key configuration to enable this capability.
Mobile Node Requirement
Following are the mandatory functional requirements on mobile node to support 3GPP2-WIMAX Interworking at HA:
The dual mode MS SHOULD use PMIP to access WIMIAX network and use CMIP to access 3GPP2 network.
The static NAI (the NAI that is pre-provisioned for access to 3GPP2) has to be used in RRQ on both 3GPP2 and
WiMAX networks.
The dual mode MS SHOULD support “make-before-break” when changing between 3GPP2 and WiMAX
networks, if coverage is available on both networks.
The CMIP4 RRQ message used on 3GPP2 network MUST contain the MN-AAA and Foreign Agent Challenge
Extension (FACE)
H-AAA Requirements
H-AAA MUST meets the following requirements to support 3GPP2-WIMAX Interworking at HA:
The H-AAA servers used by 3GPP2 and WIMAX SHOULD be either the same or they have access to the same
session state and subscriber profile.
H-AAA server SHOULD assign and return the same HA address in response to 3GPP2 and WIMAX network
