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.

[0039]The determining the time threshold corresponding to t...

Embodiment 2

[0077] Correspondingly, Embodiment 2 of the present invention provides a base station, which can implement the method for determining unnecessary handover in the above embodiment and the following application examples. Such as figure 2 As shown, the base station includes a determining module 201 and a processing module 202 .

[0078] The determining module 201 is configured to determine a time threshold corresponding to the UE characteristic attribute parameter of the UE 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, and determine the the residence time of the UE in the second cell; and

[0079] A processing module 202, configured to determine whether unnecessary handover occurs to the UE according to the time threshold corresponding to the characteristic attribute of the UE determined by the determining module 201, and the stay time of the UE in the second cell; if If the stay time is lower t...

Embodiment 3

[0109] Embodiment 3 of the present invention provides a method for determining unnecessary handover, such as image 3 As shown, the method includes the following steps.

[0110] Step 301, the first base station handovers the user equipment UE from the first cell under the first base station to the second cell under the second base station;

[0111] Step 302, if the UE is handed over from the second cell to the third cell, the first base station receives the information sent by the second base station or a third base station under the third cell to the first base station Notification of unnecessary handover, wherein the notification is when the stay time of the UE in the second cell is lower than the time threshold corresponding to the UE characteristic attribute parameter of the UE, the second base station or the sent by the third base station.

[0112] It should be noted that, in this embodiment, the second base station and the third base station may be the same or differen...

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. [0003] In the prior art, a base station configures a fixed time thresho...
