A method for facilitating return to a first wireless network from a second wireless network by a wireless communication device, the method performed by the wireless communication device comprises: engaging in packet switched data transfer for an application session via the first wireless network; adjusting one or more application layer parameters for the application session to change packet data generation or consumption by the application session prior to a Circuit Switched Fallback, CSFB, procedure to transition the wireless communication device from the first wireless network to the second wireless network; participating in the CSFB procedure to service a voice connection via the second wireless network in parallel with a data connection for continuing the application session via the second wireless network; buffering packet switched data received for the application session via the second wireless network after the CSFB procedure; releasing the voice connection with the second wireless network; discontinuing requests to the second wireless network for downlink data for the application session in response to termination of the voice connection to provide a gap in packet switched data transfer; reselecting to the first wireless network during the gap in packet switched data transfer; using the buffered packet switched data to continue the application session during reselection; readjusting one or more application layer parameters for the application session to change the packet data generation or consumption by the application session after reselection from the second wireless network to the first wireless network; and resuming packet switched data transfer for the application session via the first wireless network after completing reselection to the first wireless network. engaging in packet switched data transfer for an application session via the first wireless network; adjusting one or more application layer parameters for the application session to change packet data generation or consumption by the application session prior to a Circuit Switched Fallback, CSFB, procedure to transition the wireless communication device from the first wireless network to the second wireless network; participating in the CSFB procedure to service a voice connection via the second wireless network in parallel with a data connection for continuing the application session via the second wireless network; buffering packet switched data received for the application session via the second wireless network after the CSFB procedure; releasing the voice connection with the second wireless network; discontinuing requests to the second wireless network for downlink data for the application session in response to termination of the voice connection to provide a gap in packet switched data transfer; reselecting to the first wireless network during the gap in packet switched data transfer; using the buffered packet switched data to continue the application session during reselection; readjusting one or more application layer parameters for the application session to change the packet data generation or consumption by the application session after reselection from the second wireless network to the first wireless network; and resuming packet switched data transfer for the application session via the first wireless network after completing reselection to the first wireless network.
