Abstract: This application provides a multi-air-interface communication method and an apparatus. In the method, a mobile terminal supports a plurality of types of air interfaces. The method resolves a BSR sending problem, a PHR reporting problem, and a DRX problem in a case of a plurality of air interfaces. The method that resolves the BSR sending problem in the case of the plurality of air interfaces enables a base station to more accurately allocate a radio resource to the mobile terminal based on a BSR sent on each air interface by the mobile terminal. The method that resolves the PHR reporting problem in the case of the plurality of air interfaces enables the base station to more accurately allocate the radio resource to the mobile terminal. The method that resolves the DRX problem in the case of the plurality of air interfaces is more beneficial to power saving of the mobile terminal.

Abstract: A user equipment obtains configuration information used to detect a received signal strength indicator (RSSI) value of a signal on an unlicensed frequency, samples the signal on the unlicensed frequency at a sampling interval included in the configuration information to obtain RSSI values of the signal on the unlicensed frequency sampled at sampling moments. The user equipment determines statistics on the RSSI values of the signal on the unlicensed frequency within a statistical window, obtains an RSSI value statistical result of the signal on the unlicensed frequency based on the statistics, and reports the RSSI value statistical result to a base station.

Abstract: Embodiments of the present invention provide a method for handover between secondary base stations, a network device, and user equipment. The network device instructs each of at least one candidate secondary base station to make a prior path handover preparation, so that each of the at least one candidate secondary base station waits to be selected by user equipment as a target secondary base station. The path handover preparation includes at least one of the following: preconfiguring an access resource for the user equipment or establishing a data transmission channel with the network device. The user equipment is handed over to the target secondary base station in the at least one candidate secondary base station according to configuration information of each of the at least one candidate secondary base station when the user equipment needs path handover.
