Cell switching method and device

Abstract

The invention discloses a cell switching method and device, and aims to solve problems that, when the UE (User equipment) is used for cell switching, the frequent UE switching makes the signaling cost increase, the switching delay increase, and the communication quality affected. The cell switching method comprises the following steps that: a measurement report sent by the UE is received; according to the measurement report, a target cell meeting a preset condition is filtered so as to generate a target cell list; a switching request message is sent to all target cells of the target cell list; when a confirmation message which is fed back by the target cell is received in a preset duration, according to related parameter information of the target cell, the target cell in the target cell list are sorted in order of priority, and based on the sorted result, the target cell list is updated; and the UE is instructed to switch to the target cell in the highest priority in the updated target cell list. With application of the technical scheme of the invention, the success rate of the cell switching by the UE can be effectively improved, the time delay in the multiple switching is reduced, and the call quality is guaranteed.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell switching method and device. Background technique [0002] In mobile communication technology, the propagation characteristics of mobile signals and the mobility characteristics of UE (User equipment, user equipment) will cause dynamic changes in mobile signals and interference signals around UE. For example, when UE moves from a cell within the coverage of a base station When moving to a cell within the coverage of another base station, or when the UE is located at the boundary of a cell within the coverage of the base station, the mobile signal around the UE will change. At this time, in order to ensure the continuous communication between the UE and the mobile network, maintain the required service QoS (Quality of Service, service quality), enable users to connect with base stations with better signal quality, and realize hierarchical cell communication in hotspot area...
