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

Embodiment Construction

[0031] In order to solve the problem that the prior art adopts artificial configuration parameters and switches to an artificially set neighboring cell reported by the terminal, the handover success rate is not high. In the solution of the present invention, a target cell is selected for the terminal according to the acquired current load information of the neighboring cell of the terminal and the RSRP information of the neighboring cell and the serving cell.

[0032] The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings of the specification, such as figure 2 As shown, a method for selecting a target cell in a handover process according to an embodiment of the present invention includes the following steps:

[0033] S201: Obtain RSRP information of the current neighboring cell and serving cell of the terminal.

[0034] S202: Select a target cell for the terminal according to the acquired current load informatio...

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 field of LTE communication technology, and in particular to a method, equipment 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 X2 is the communication interface between the base station and the base station. The S1 and X2 interfaces are the most basic two interfaces. In the process of moving the terminal, there are generally two switching methods: switching through the S1 interface or the X2 interface. [0003] In the prior art, a neighboring cell is selected as a target cell based on the measurement report of the UE, and a reasonable handover trigger condition is designed to avoid triggering unnecessary handover procedures and to prevent users from dropping calls. When the selected target cell and the source cell belong to different base st...
