Assisting return to a first network from a second network after performance of a circuit switched fallback procedure
Abstract:
A method for assisting a wireless communication device to return to a first network from a second network is provided. The method can include the wireless communication device participating in a CSFB procedure to transition from the first network to the second network for servicing of a voice call; receiving a connection release from the second network after termination of the voice call; initiating a reselection procedure to reselect to the first network; determining presence of packet switched data ready for transmission from the wireless communication device before completion of the reselection procedure; holding the packet switched data at the wireless communication device at least until expiry of a reselection timer initiated during the reselection procedure; reselecting to the first network after expiry of the reselection timer; and initiating transmission of the packet switched data on the first network after completing reselection to the first network.
