Patent ID: 8923861

Claim:
A method for facilitating reselection by a wireless communication device to a Long Term Evolution (LTE) network from a legacy network after termination of a voice call for which a Circuit Switched Fallback (CSFB) procedure is performed, the method comprising: by the wireless communication device: performing measurement of the LTE network while the wireless communication device is connected to the LTE network; participating in a circuit switched fallback (CSFB) procedure to transition from the LTE network to the legacy network in response to initiation of the voice call; performing measurement of the legacy network during the voice call; determining based at least in part on one or more of the measurement of the LTE network and the measurement of the legacy network whether the wireless communication device is in a mobility state such that the wireless communication device is not static; deriving a predicted reference signal received power (RSRP) of the LTE network after termination of the voice call based at least in part on the measurement of the LTE network performed while the wireless communication device was connected to the LTE network; releasing a packet switched radio access bearer on the legacy network and attempting reselection to the LTE network in an instance in which the predicted RSRP satisfies a threshold RSRP; and remaining on the legacy network and continuing a packet switched session over the packet switched radio access bearer in an instance in which the predicted RSRP does not satisfy the threshold RSRP.
