subscribers. With the implementation of this feature, the HA can be configured for:
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:
