System and method for preserving session context during inter-radio access technology service retry

A user equipment comprising:

• a wireless communication device for communicating over at least a first network and a second network;
• a processing device coupled to the wireless communication device and configured to:
• ascertain that a first service over a wireless communication session with a first network has failed;
• send a service request for a second service to the first network, where the second service is distinct from the first service and has the effect of suspending the wireless communication session with the first network;
• and
• resend the data transmission for the failed first service over the second network.

A user equipment, comprising:

• means for initiating a data transmission for a first service over a wireless communication session with a first network;
• means for ascertaining that the first service has failed over the first network;
• means for sending a service request for a second service to the first network, where the second service is distinct from the first service and has the effect of suspending the wireless communication session with the first network;
• and
• means for resending the data transmission for the failed first service over a second network.

A processor-readable medium having one or more instructions operational on a user equipment for facilitating transparent retransmission of a failed service, which when executed by a processor causes the processor to:

• initiate a data transmission for a first service over a wireless communication session with a first network;
• ascertain that the first service has failed over the first network;
• send a service request for a second service to the first network, where the second service is distinct from the first service and has the effect of suspending the wireless communication session with the first network;
• and
• resend the data transmission for the failed first service over a second network.

A method operational on a packet-switched network device for a first network, comprising:

• receiving a data transmission for a first service over a wireless communication session with a user equipment;
• sending a service failure indicator to the user equipment indicating that the data transmission for the first service has failed;
• and
• receiving a service request for a second service from the user equipment, where the second service is distinct from the first service and has the effect of suspending the wireless communication session with the user equipment.

A packet-switched network entity comprising:

• a wireless communication device for communicating with one or more user equipment and a core network;
• a processing device coupled to the wireless communication device and configured to:
• receive a data transmission for a first service over a wireless communication session with a user equipment;
• send a service failure indicator to the user equipment indicating that the data transmission for the first service has failed;
• and
• receive a service request for a second service from the user equipment, where the second service is distinct from the first service and has the effect of suspending the wireless communication session with the user equipment.

A packet-switched network entity for a first network, comprising:

• and
• means for receiving a service request for a second service from the user equipment, where the second service is distinct from the first service and has the effect of suspending the wireless communication session with the user equipment.
