A wireless local area network, WLAN, measurement and reporting method, comprising: receiving, by a user terminal, WLAN measurement configuration information sent by a base station, wherein the WLAN measurement configuration information comprises at least one measurement event; acquiring, by the user terminal, WLAN group information from the base station, wherein the WLAN group information is used to indicate at least one WLAN group, wherein each WLAN group among the at least one WLAN group includes at least two WLANs; determining, by the user terminal, whether at least one WLAN in the WLAN group satisfies a measurement event in the WLAN measurement configuration information; and reporting, by the user terminal, a measurement result of the at least one WLAN in the WLAN group to the base station when the at least one WLAN in the WLAN group satisfies the measurement event; wherein the WLAN group comprises a serving WLAN group or a serving WLAN group and a neighboring WLAN group; the WLAN measurement configuration information comprises at least one of the following measurement events: a measurement event 1: signal quality of all WLANs in the serving WLAN group is less than a first threshold; or a measurement event 2: signal quality of at least one WLAN in the neighboring WLAN group is greater than a second threshold and signal quality of all WLANs in the serving WLAN group is less than a third threshold; and the serving WLAN group is a WLAN group to which a WLAN associated with the user terminal belongs, and the neighboring WLAN group is another WLAN group that does not comprise the WLAN associated with the user terminal. receiving, by a user terminal, WLAN measurement configuration information sent by a base station, wherein the WLAN measurement configuration information comprises at least one measurement event; acquiring, by the user terminal, WLAN group information from the base station, wherein the WLAN group information is used to indicate at least one WLAN group, wherein each WLAN group among the at least one WLAN group includes at least two WLANs; determining, by the user terminal, whether at least one WLAN in the WLAN group satisfies a measurement event in the WLAN measurement configuration information; and reporting, by the user terminal, a measurement result of the at least one WLAN in the WLAN group to the base station when the at least one WLAN in the WLAN group satisfies the measurement event; wherein the WLAN group comprises a serving WLAN group or a serving WLAN group and a neighboring WLAN group; the WLAN measurement configuration information comprises at least one of the following measurement events: a measurement event 1: signal quality of all WLANs in the serving WLAN group is less than a first threshold; or a measurement event 2: signal quality of at least one WLAN in the neighboring WLAN group is greater than a second threshold and signal quality of all WLANs in the serving WLAN group is less than a third threshold; and the serving WLAN group is a WLAN group to which a WLAN associated with the user terminal belongs, and the neighboring WLAN group is another WLAN group that does not comprise the WLAN associated with the user terminal. a measurement event 1: signal quality of all WLANs in the serving WLAN group is less than a first threshold; or a measurement event 2: signal quality of at least one WLAN in the neighboring WLAN group is greater than a second threshold and signal quality of all WLANs in the serving WLAN group is less than a third threshold; and the serving WLAN group is a WLAN group to which a WLAN associated with the user terminal belongs, and the neighboring WLAN group is another WLAN group that does not comprise the WLAN associated with the user terminal.
