ABSTRACT:
The techniques introduced herein provide a system and method for determining whether an inter-RAT handover is an SRVCC handover, and for performing the subsequent SRVCC handover. The techniques include receiving a handover command message that does not include SRVCC related information elements, for example “RAB info to replace,” but continuing with an SRVCC handover using a circuit-switched RAB provided in the information for setup. The techniques also include receiving a handover command message that does include SRVCC related information elements and performing the SRVCC handover by an alternative method.
