Summary:A method is provided for facilitating preservation of session context information during an inter-radio access technology service retry. A user equipment (UE) may initiate a data transmission for a first service over a wireless communication session with a first network. Upon ascertaining that the first service has failed over the first network, a failover procedure is initiated by sending a service request for a second service to the first network. The second service may be distinct from the first service and has the effect of suspending the wireless communication session with the first network. The UE then resends the data transmission for the first service over a second network. The UE then resumes use of the wireless communication session over the first network after resending the data transmission over the second network. This resumption is done by using context information for the wireless communication session preserved prior to the suspension.
