OL-22953-01
With this configuration, both WiMAX- and 3GPP2-based calls can be made. WiMAX-based calls use WiMAX MIP
keys, and 3GPP2 calls can use static or 3GPP2-based dynamic keys. The HA service supports calls of both access
technologies.
keys, and 3GPP2 calls can use static or 3GPP2-based dynamic keys. The HA service supports calls of both access
technologies.
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.
it changes its active network attachment from 3GPP2 to Wimax and vice versa.
This capability provides the following benefits:
Common billing and customer care
Accessing home 3GPP2 service through Wimax network and vice versa
Seamless session continuity with no perceived impact from a user’s perspective
To provide this capability, the HA supports the seamless handoff from 3GPP2 to WiMAX, or WiMAX to 3GPP2.
This section describes how to configure session continuity.
Mobile Node Requirement
Following are the mandatory functional requirements for the mobile node to support 3GPP2-WiMax Interworking at the
HA:
HA:
The dual-mode MS must use PMIP to access the WIMIAX network and use CMIP to access 3GPP2 network.
The static NAI (the NAI that is pre-provisioned for access to 3GPP2) must be used in RRQs on both 3GPP2 and
WiMAX networks.
The dual-mode MS must 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 meet the following requirements to support 3GPP2-WiMax Interworking at HA:
The H-AAA servers used by 3GPP2 and WiMax must be the same or have access to the same session state and
subscriber profile.
H-AAA server must assign and return the same HA address in response to 3GPP2 and WiMax network access
requests.
