Session Continuity Support for 3GPP2 and WiMAX Handoffs
From Release 7.1, this feature provides the seamless session mobility for WiMAX 
subscriber and other access technology subscribers; i.e. 3GPP2. By implementation of this 
feature HA can be configured for:
3GPP2 HA Service
3GPP HA Service
WiMAX HA Service
Combination of 3GPP2 and WiMAX HA Service
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 user impacts 
from a user experience 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
This feature requires a separate license to enable WiMAX service.
