Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] In the embodiment of the present invention, the source base station refers to the base station corresponding to the serving cell where the current user terminal (UE) is located; the target base station refers to the cell that the UE will switch into after leaving the source cell, that is, the base station corresponding to the target cell;

[0023] In addition, various cell handover methods are used in existing wireless networks, incl...

Abstract

The invention discloses a cell handover method and a base station thereof. The method comprises the following steps that a source base station obtains a measurement report, which is reported by user equipment UE within a preset time bucket, wherein the measurement report comprises a receiving signal quality value of each measurement cell; the source base station determines a change value of the receiving signal quality value of each measurement cell within the set time bucket according to the measurement report; the source base station determines the measurement cell with the maximum change value of the receiving signal quality value as a target cell of the UE; and when the source base station determines that the target cell meets handover decision conditions, the source base station executes cell handover for the UE. The cell handover method and the base station thereof are used for solving a problem of frequent handover of the UE in an overlapping region in the prior art.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a cell switching method and a base station thereof. Background technique [0002] In a wireless communication system, when the UE is at the edge of the serving cell, the signal quality of the serving cell becomes weaker and the signal quality of the adjacent cell becomes stronger, which will trigger the UE to report a measurement report, and the serving base station will judge whether to perform cell handover based on the measurement report , that is, to complete channel switching between the UE and the base station. In other words, when the UE leaves a cell and enters another cell, as the signal of one cell weakens and the signal of another cell increases, the base station corresponding to the weakened cell signal will trigger the handover process, so that the UE will switch to a cell with a strong signal. district. In order to realize the session continuity of the UE duri...
