Problems solved by technology

[0005] However, the VoLTE service is a multimedia voice network based on IP transmission technology. Its call quality is not only related to the quality of the wireless environment, but also related to the packet loss rate, delay, delay jitter, and switching status of VoIP packets. These indicators directly affect the perception of VoLTE users. In the scenario where these indicators continue to deteriorate, it will cause problems such as single communication, intermittent, and poor quality for users.

Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] figure 1 It is a flow chart of a VoLTE service switching method provided by an embodiment of the present invention, such as figure 1 As shown, the method includes:

[0036] S1. Calculate the voice quality of the user in the target cell based on a preset voice quality detection algorithm, wherein the target cell includes the current cell and several adjacent cells;

[0037] S2. If the voice quality of the user in the current cell is lower than the first preset threshold, select an adjacent cell with the highest voice quality for handover.

[0038] In the prior art, since the VoLTE service completely inherits the switching strategy of the LTE data service, it can o...

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,...
