Interoperability decision method and device with WLAN (wireless local area network) in terminal cell switching

The invention discloses an interoperability decision method and device with a WLAN (wireless local area network) in terminal cell switching. The method comprises the following steps that if UE (user equipment) judges that the WLAN shunting conditions are met according to the network side configured WLAN interoperability decision criterion, the WLAN shunting is delayed or canceled; if the reporting condition of the measurement report of the WLAN shunting is met, the reporting of the measurement report of the WLAN shunting is delayed or canceled. When the method and the device are adopted, the problems of resource waste and energy waste possibly caused by shunting between a 3GPP access network and the WLAN in the terminal cell switching process are at least solved.
