Method, equipment and system for selecting target cell during handover

Abstract

The invention provides a method for selecting a target cell during handover. The target cell is selected according to the load and the signal quality of neighbor cells, the handover is not conducted according to an artificially set target cell and the quality of cell handover is improved. The method comprises the steps of: obtaining the reference signal received power (RSRP) information of the current neighbor cells and the serving cell of a terminal; and selecting the target cell for the terminal according to the obtained current load information of the neighbor cells of the terminal and the obtained RSRP information of the neighbor cells and the serving cell. The invention additionally provides corresponding equipment and a corresponding system, which can be used for making comparisons between the cell load and downlink signal quality to find out a high-quality cell for handover.

Description

technical field [0001] The present invention relates to the technical field of LTE communication, in particular to a method, device and system for selecting a target cell in a handover process. Background technique [0002] In the LTE communication system, the S1 interface is the communication interface between the base station and the packet core network, and the X2 is the communication interface between the base station and the base station. The S1 and X2 interfaces are the two most basic interfaces. During the mobile process of the terminal, there are generally two switching modes: switching through the S1 interface or the X2 interface. [0003] In the prior art, a neighboring cell is selected as a target cell according to the UE's measurement report, and reasonable handover trigger conditions are designed to avoid triggering unnecessary handover processes and avoid user call drop. When the selected target cell and the source cell belong to different base stations, the s...

AI Technical Summary

Problems solved by technology

In the existing method, only through the fixed configuration of S1 or X2 handover in the adjacent cell, the handover is handed over to the artificially set adjacent cell reported by the terminal, which cannot be changed according to the actual situation, resulting in a low handover success rate

Manually configuring neighboring cells based on geographical information cannot actually reflect the status of neighboring cells measured by the terminal, and cannot switch to a more suitable neighboring cell, which also affects the success rate of handover
