Abstract
A mobile station has a transmitter, a first receiver, and a second receiver, each of which can be configured to use a first radio access technology and a second radio access technology. The mobile station uses the transmitter and the first receiver to engage in a communication session via a serving base station that uses the first radio access technology. When a degradation in quality of the communication session is detected, the mobile station evaluates a target base station by transmitting a trial communication to the serving base station and receiving, through the second receiver, a trial response from a target base station. The target base station uses the second radio access technology. If the trial response is acceptable, the mobile station requests a handover of the communication session to the target base station. The mobile station may select the target base station from a multi-technology neighbor list.
