Speech service processing method, device and terminal

Abstract

The application provides a speech service processing method, a device and a terminal. The method comprises the following steps: firstly judging whether a number corresponding to an ongoing speech service of the terminal is a preset number; if the number corresponding to the ongoing speech service of the terminal is the preset number, determining the current RAT mode of the terminal, and controlling the terminal to maintain at the current wireless access technology model within the preset slot after the speech service is finished. Therefore, the terminal cannot perform network reselection within the preset time slot after communicating with the preset number, thereby avoiding the speech service failure caused by network reselection, a success rate and the reliability of the speech service with the preset number are improved, the success of timely getting the rescue by a user under the emergency is improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a voice service processing method, device and terminal. Background technique [0002] With the rapid development of Radio Access Technology (RAT) and terminal technology, there are more and more network forms that communication terminals can access. For example, the fourth generation mobile communication (the 4 th Generation Mobile Communication, referred to as 4G), the third generation mobile communication (the 3 rd Generation MobileCommunication, referred to as 3G), even 5G and so on. And according to the Third Generation Partnership Project (3 rd The Generation Partnership Project (3GPP for short) and other agreements stipulate that when a communication terminal is in an idle state, it should be able to reselect and camp on a qualified network cell with a higher priority. [0003] Since newer RATs can often bring better network experience to users, ne...

Problems solved by technology

[0005] However, if the voice service initiated by the user is an emergency call, and the emergency call is abnormally disconnected, the emergency station may need to contact the caller again through an emergency callback. If the terminal is trying to reselect to a 4G network cell, it is very likely that the communication terminal cannot respond to the emergency callback in time because of the reselection action, which will cause the emergency callback to fail; or the communication terminal has reselected to 4G network, after receiving the paging message, the communication terminal needs to fall back from the 4G network to the 2G (or 3G) network through CSFB technology to respond to the paging message. If CSFB fails at this time, it will also cause this emergency callback failed
