Patent ID: 8744446

Claim:
A method comprising a mobile wireless communication device: sending to a wireless network a first measurement message generated based at least in part on a first channel quality measurement in unassured mode; determining whether a handover message is received from the wireless network within a timeout period following sending the first measurement message; in an instance in which it is determined that the handover message is received from the wireless network within the timeout period, participating in a handover; in an instance in which it is determined that the handover message is not received from the wireless network within the timeout period: determining an updated channel quality measurement; sending to the wireless network a new measurement message generated based at least in part on the updated channel quality measurement in unassured mode; determining whether the handover message is received from the wireless network within a second timeout period following sending the new measurement message; and repeating determination of the updated channel quality measurement and sending to the wireless network an updated measurement message generated based at least in part on a most recently updated channel quality measurement until either the handover message is received from the wireless network within a subsequent timeout period following a most recently sent measurement message or a threshold number of measurement messages are sent to the wireless network; and in an instance in which the threshold number of measurement messages are sent to the wireless network without receiving from the wireless network the handover message within the subsequent timeout period following a last sent measurement message, dropping an ongoing session between the mobile wireless communication device and the wireless network.
