Session Continuity Support for 3GPP2 and WiMAX Handovers
This feature provides seamless 3GPP2 session mobility for WiMAX subscribers and other access technology
subscribers. With the implementation of this feature, the HA can be configured for:
3GPP2 HA service
3GPP HA service
WiMAX HA service
A combination of 3GPP2 and WiMAX HA services
The above configurations provide the session continuity capability that 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 impact from a user perspective. This capability brings 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
For more information on this support, refer to the HA Administration Guide.
