Abstract

The invention provides a VoLTE service switching method, which comprises the following steps: S1, calculating the voice quality of a user in a target cell based on a preset voice quality detection algorithm, wherein the target cell comprises a current cell and a plurality of adjacent cells; S2, if the voice quality of the user in the current cell is lower than a first preset threshold, selecting the adjacent cell with the highest voice quality for handover. The VoLTE service switching method and system provided by the invention can detect the voice quality of the user at a network side, thereby controlling the user to switch to a cell with better voice perception and avoiding the problem of deterioration of the user perception to the maximum extent.

Description

technical field

[0001] The present invention relates to the technical field of mobile communication, and more specifically, to a VoLTE service switching method and system. Background technique

[0002] Handover is an indispensable and important function of the mobile communication system. Specifically, it refers to the process of switching the communication channel from one wireless channel to another under the premise of ensuring uninterrupted communication during the mobile communication process. function. Generally, a handover is triggered when the mobile station moves from one base station coverage area to another base station coverage area or the communication quality is degraded due to external interference or other reasons.

[0003] In the LTE network, the prior art adopts a mobile-assisted handover (MAHO) strategy, that is, the network requires the mobile station to measure the surrounding signal strength and report it to the network side according to certain rules,...
