Abstract: The present disclosure discloses a method for reporting a measurement report of a measurement event, including: determining that a measurement event is generated in a user equipment (UE) in an activated state of discontinuous reception (DRX) mode; judging whether a first time to trigger corresponding to the measurement event is valid when it is determined that there is a measurement event generated; using, when it is judged that the first time to trigger is valid, the first time to trigger to time the measurement event; using, when it is judged that the first time to trigger is invalid, a second time to trigger to time the measurement event, such that the UE is in next one or next several activated states of DRX mode after the generation of the measurement event. The present disclosure can improve a success rate of mobility handover between cells or wireless link quality.

Abstract: A radio connection re-establishment where first preset numbers and/or durations are obtained. The multiple present numbers and/or durations correspond to one or more of, different cell coverage ranges of different types of cells, different transmit power strengths of the different types of cells, physical cell identifiers (PCIs) of the different types cells, types of the different types of cells, and/or first ranges of the different types of cells. A first range of a cell, among the different types of cells, is a range in which a signal strength of the cell in a coverage range of a macro cell, among the different types of cells, is greater than a signal strength of a macro cell among the different types of cells. The first present numbers and/or durations are sent to a user equipment (UE).

Abstract: Embodiments of the present disclosure disclose a message broadcast method, a base station, and user equipment. The message broadcast method includes: determining, by a base station, a piece of system subgroup information of system information of a first cell, where each piece of system subgroup information includes system information content that is applied to a user equipment group that corresponds to the system subgroup information. The method also includes broadcasting, to the user equipment group, the system subgroup information that corresponds to the user equipment group. In such a manner, system information that is generated due to a requirement of a new technology can be effectively reduced, and user equipment can be prevented from receiving information unrelated to the user equipment and triggering unnecessary behavior.
