Abstract

The invention provides a voice calling method, a voice calling device and a terminal, wherein the voice calling method comprises the following steps of: determining whether a signal radio voice call continuity (SRVCC) call forwarding instruction is received or not after a voice calling request of an IP multimedia subsystem IMS is initiated; falling back to a 3G network or a 2G network while determining that the SRVCC call forwarding instruction is received; judging whether configuration information of a current cell supports a circuit switch (CS) domain service or not according to the SRVCC call forwarding instruction; and if so, directly executing a CS voice call, otherwise, initiating a location registration process LAU in the current cell. By means of the technical scheme of the invention, the problem that the CS voice call is failed in the event that a 4G network only supports a PS service after being subjected to SRVCC call forwarding and falling back to a 3G or 2G network can be avoided; the calling success rate is increased; and the user experience in the voice calling process is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a voice call method, a voice call device and a terminal. Background technique [0002] At present, VoLTE technology, namely VoiceoverLTE, is a voice service based on IMS (Multimedia Subsystem). The application of VoLTE technology is also becoming more and more extensive. By using VoLTE technology, the waiting time for call connection can be shortened and the call quality can be improved. [0003] When an existing VoLTE terminal initiates an IMS voice service, the network evaluates whether the network needs to switch the call to the circuit-switched domain CS according to the network coverage quality of the current terminal. If it needs to switch to the circuit-switched domain CS, it will trigger SRVCC (voice Business Continuity Solution) process for session transfer, so that the voice call is transferred from the 4G network to the 3G network or 2G network.
