FACILITATING RETURN TO A FIRST WIRELESS NETWORK FROM A SECOND WIRELESS NETWORK AFTER PERFORMANCE OF A CIRCUIT SWITCHED FALLBACK PROCEDURE

摘要

Method and apparatus for facilitating return to a first wireless network from a second wireless network by a wireless communication device is provided. A method includes the wireless communication device engaging in data transfer for an application session on the first wireless network; participating in a CSFB procedure to transition from the first wireless network to the second wireless network for servicing a voice connection; buffering data received for the application session before and/or during the CSFB procedure; releasing the voice connection; discontinuing requests for downlink data for the application session in response to termination of the voice connection to provide a gap in data transfer; reselecting to the first wireless network during the gap in data transfer; using the buffered data to continue the application session during reselection; and resuming data transfer for the application session on the first wireless network after completing reselection.
