1. A method for determining an unnecessary handover, the method comprising:
in response to a user equipment (UE) being handed over from a first cell to a second cell and then handed over from the second cell to a third cell:
receiving, by a first base station, related information from a second base station that serves the second cell or from a third base station that serves the third cell, wherein the related information comprises a stay time of a user equipment (UE) in the second cell and a UE characteristic attribute parameter of the UE, and the related information is sent by the second base station or the third base station when the stay time of the UE in the second cell is shorter than a default time threshold,
determining, by the first base station, a time threshold corresponding to the UE characteristic attribute parameter of the UE, and
determining, by the first base station, that an unnecessary handover of the UE occurs according to the stay time comprised in the related information and the determined time threshold when the stay time of the UE in the second cell is shorter than the time threshold;
wherein the UE characteristic attribute parameter comprises at least one of a service type, a quality of service (QoS) parameter of a service, and a subscriber profile ID (SPID) of the UE.
