Embodiment Construction

[0055] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0056] The load balancing function is used to balance the load between cells, frequencies and radio access technologies. This function can balance the performance of the whole system and improve the stability of the system. This function is to reasonably deploy cell operating traffic according to the load status of the serving cell and its neighboring cells, and effectively use system resources to increase system capacity and system stability. In general, the load balancing function can be divided into three stages.

[0057]During the measurement phase, the load status of the serving cell and the load status of neighboring cells are continuously monitored and updated. If there is an X2 interface, the load information of neighboring cells of different s...

Abstract

The invention provides a cell switching method and device. The cell switching method comprises the steps of obtaining a same-coverage adjoined cell group having a same-coverage relationship with an adjoined cell measured and reported by UE of a current access source cell; determining one cell from the same-coverage adjoined cell group as a target cell based on the load state of each cell in the same-coverage adjoined cell group; and indicating the UE to be switched from the source cell to the target cell. According to the cell switching method and device, unnecessary switching can be reduced to a great extent, the system load is reduced and the UE can be switched to the target cell rapidly and directly.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a cell switching method and device. Background technique [0002] A significant difference between a mobile communication system and a fixed communication system lies in "mobility". In a mobile communication system, the location of UE (User Equipment, user equipment) is constantly changing. Since the coverage of a single cell is always limited, in order not to affect user experience, it is necessary to constantly change the serving cell for the UE. In an LTE (Long Term Evolution, long term evolution) system, when the UE is in the RRC_CONNECTED (Radio Resource Control Connected, radio resource control connected) state, mobility is mainly accomplished by handover or redirection. [0003] Handover is mainly divided into three stages: handover-related measurement delivery, handover judgment, and handover execution. The base station sends the measurement configuration for hando...
