Abstract: The present invention provides a method for determining an unnecessary handover and a base station. The method includes: if a user equipment UE is handed over from a first cell to a second cell, and then handed over from the second cell to a third cell, determining, by a base station, a time threshold corresponding to a UE characteristic attribute parameter of the UE, and a time of stay of the UE in the second cell; determining, by the base station according to the time threshold corresponding to a UE characteristic attribute and the time of stay of the UE in the second cell that are determined, whether an unnecessary handover of the UE occurs; and determining that an unnecessary handover of the UE occurs if the time of stay is shorter than the time threshold. The present invention optimizes a method for determining whether an unnecessary handover occurs.

Abstract: A method of facilitating identification of a user equipment (UE) is disclosed. A first network control node (NCN) receives an radio link failure (RLF) indication message including a first mobile identity indicator (MII) of a UE. The first NCN determines a second MII of the UE, the second MII being associated with the first MII, and a second NCN associated with the second MII. And the first NCN sends the second MII to the second NCN.

Abstract: Methods, devices, and computer-readable storage media are provided. A method includes sending, by a first network device, a first request message to a second network device, where the first request message comprises first indication information, the first indication information indicates a priority of at least one resource parameter, and the first request message requests to feed back a measurement value of the at least one resource parameter. The method includes receiving, by the first network device, a first response message sent by the second network device, where the first response message comprises a measurement value of a first resource parameter in the at least one resource parameter.

Abstract: A link failure report transmission method and apparatus are provided. When a link between a terminal and a first radio access network device fails, and a master radio access network device of the first radio access network device is handed over, the terminal sends a first link failure report to a second radio access network device, so that the second radio access network device forwards the first link failure report to a third radio access network device, and the third radio access network device sends the first link failure report to the first radio access network device. In this way, the first radio access network device can perform parameter adjustment based on the first link failure report.
