摘要： Embodiments of the present invention provide a method and an apparatus for detecting a cell identity conflict. The method includes: determining that a user equipment accesses a first cell or performs connection establishment or connection re-establishment in a first cell at a first time point T1; searching whether interaction information related to the user equipment exists in other cells except the first cell near the first time point T1; and performing cell identity conflict detection on the first cell and a second cell when it is found, through the searching, that the interaction information related to the user equipment exists in the second cell among the other cells near the first time point T1. The embodiments of the present invention do not rely on a neighboring cell list and an operation of reporting cell information by a user equipment, thereby improving detection efficiency of a cell identity conflict.

摘要： Embodiments of this application provide a method and an apparatus for acquiring context information of user equipment. The method includes: receiving, by a first network-side device, a measurement report sent by user equipment; determining a handover target cell and a candidate cell according to the measurement report and a first neighboring-cell configuration relationship; and separately sending context information of the user equipment to a second network-side device to which the handover target cell belongs and a third network-side device to which the candidate cell belongs, where the context information is used to re-establish a radio resource control RRC connection between the user equipment and the second network-side device or the third network-side device when a handover fails. According to the embodiments of this application, a probability that user equipment re-establishes an RRC connection to a cell having context information is increased, which facilitates rapid recovery of a service.

摘要： Embodiments of the present invention provide a communication method and a communications device. The method includes: sending, by a base station, a message including measurement configuration to UE, where the measurement configuration is used to request the UE to report a cell global identifier of a cell; obtaining, by the base station, a measurement report reported by the UE, where the measurement report corresponds to the measurement configuration and includes the cell global identifier of the cell and band information of the cell; and performing, by the base station, cell handover based on the band information and the cell global identifier of the cell. By means of the present invention, the base station obtains complete and accurate band information of the cell, so that the base station can perform accurate handover decision, thereby avoiding handover failure.
