Abstract

Disclosed are measurement method and device, information interchange method and device and residence method and device. The measurement method includes configuring measurement configuration information about a UE and sending same, the measurement configuration information including a measurement report trigger condition for a reference cell, so that the UE reports a measurement result when satisfying the measurement report trigger condition. The information interchange method includes interchanging discontinuous data transmission parameter configuration information with a fourth base station, so that a base station side executes scheduling and/or mobility management on a user equipment. The residence method includes sending indication information to a UE, the indication information being used for indicating whether the UE can reside in this cell or not, an object of the UE that can be resident, an object of the UE that cannot be resident, and at least one of the size and type of the cell.
