Methods and Base Stations for Determining Unnecessary Handovers

Abstract

The invention provides a method and a base station for determining unnecessary handover. In one aspect, the method includes: if the user equipment UE is handed over from the first cell to the second cell, and then from the second cell to the third cell, the base station determines the time threshold corresponding to the UE characteristic attribute parameter of the UE, and Determining the stay time of the UE in the second cell; the base station judges whether the UE An unnecessary handover occurs; if the stay time is lower than the time threshold, it is determined that the UE has an unnecessary handover. The present invention optimizes the method of determining whether unnecessary handover occurs.

Description

technical field

[0001] The invention relates to the field of wireless communication, in particular to a method and a base station for determining unnecessary handover. Background technique

[0002] In the 3rd Generation Partnership Project (3GPP), the base station sends a measurement configuration message to the served user equipment (User Equipment, UE) to instruct the UE to measure the source cell and the adjacent cells of the source cell. Signal quality. When the signal quality of the adjacent cell meets the handover condition, the UE reports the measurement result to the source base station. The source base station decides whether to perform handover according to the measurement report reported by the UE. In some cases, for example, the UE is fast, or the UE passes by the cell edge, etc., the UE may switch from cell 1 to another cell 2, stay in cell 2 for a short time, and then switch to cell 3.

Embodiment 1

[0036] Embodiment 1 of the present invention provides a method for determining unnecessary handover, such as figure 1 As shown, the method includes the following steps.

[0037] Step 101, if the user equipment UE is handed over from the first cell to the second cell, and then from the second cell to the third cell, the base station determines the time threshold corresponding to the UE characteristic attribute parameter of the UE, and determines that the UE is in The residence time of the second cell.

[0038] In this embodiment, different UE characteristic attribute parameters correspond to different time thresholds. There may be multiple correspondences between UE characteristic attribute parameters and time thresholds, for example, one or more UE characteristic attribute parameters correspond to one time threshold. The corresponding relationship described below is the same as this and will not be repeated here.
