AI Technical Summary

Problems solved by technology

If the signal of cell 1 is strong, but due to the large interference around cell 1 or other factors, the handover of the terminal from the source cell to cell 1 is unsuccessful, resulting in packet loss or call drop

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. 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.

[0032] At present, in areas with weak coverage or high interference scenarios of the LTE system, the terminal can realize the interaction between the LTE system and other systems (for example, UTRA system and GSM system) during the movement process, effectively realizing different services for different users (for example, data services and voice services), so as to improve the utilization of network resources. In other systems, there may be mi...

Abstract

The invention discloses a cell switching method and device. The base station receives neighbor cell information sent by the terminal, determining at least one neighbor cell satisfying the parameters included in the neighbor cell information in the configuration information; according to the embodiment of the invention, when the priority of the first neighbor cell in the at least one neighbor cellis determined to be greater than the preset priority, the terminal is switched from the serving cell to the first neighbor cell, and the higher the cell switching success rate is ensured by judging the priority of the cells, so that the packet loss rate and the offline rate in the switching process are reduced, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a cell switching method and device. Background technique [0002] With the development of communication technology, the distribution of wireless base station sites in densely populated urban areas is gradually becoming denser. When the original frequency resources remain unchanged and urban buildings become more and more complex, the network structure becomes more and more complex. High, so some areas have problems such as weak coverage and high interference. [0003] Currently, in weak coverage or high interference areas of Long Term Evolution (LTE), LTE usually interacts with other systems to realize offloading of different services for different users. Since the second generation wireless communication technology (2-Generation, 2G) network may have the situation of missing configuration of adjacent cells, it is impossible to switch cells in time. In the prior ar...
