Embodiment Construction

[0070] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0071] In the prior art, when a terminal supporting VoLTE communication capability is registered in the EPS domain and successfully registers with the IMS network, it will preferentially select the VoLTE mode for voice communication, and when the signal quality of the LTE network is lower than the preset threshold, the wireless voice continuity ( Single Radio Voice Call Continuity, SRVCC) technology is switched to 2G / 3G network to use CS mode for v...

Abstract

The invention discloses a determination method and device for a voice communication network. The method comprises the steps that a terminal in support of a VoLTE (Voice over Long Term Evolution) obtains a network frequency point at which the terminal currently resides, and the voice indicator information and signal quality information of the network frequency point, when a voice communication demand is detected, wherein the signal quality information may comprise reference signal receiving power and a signal to noise ratio, and the voice indicator information may comprise a call success rate, a call drop rate and an SRVCC (Single Radio Voice Call Continuity) switching rate; and the terminal determines the voice communication network of the terminal based on the voice indicator information and the signal quality information. In this way, the terminal can carry out comprehensive judgment according to the voice indicator information and signal quality information corresponding to the frequency point of a service cell of the terminal, the suitable voice communication network is selected, the voice call quality of the terminal is improved, moreover, SRVCC switching signal processes are reduced, and network loads are reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for determining a voice communication network. Background technique [0002] There are currently three types of voice technologies: LTE and simultaneous voice support (Simultaneous Voice and LTE, SVLTE) technology & LTE and GSM simultaneous support (Simultaneous GSM and LTE, SGLTE) technology, circuit switched fallback (Circuit Switched Fallback, CSFB) technology and LTE network voice service (Voice over LTE, VoLTE) technology, wherein: [0003] SVLTE&SGLTE is a single-card dual-standby working mode. The terminal works under the Long Term Evolution (LTE) network and the 2G / 3G network at the same time. The data service of the terminal uses the LTE network, and the voice service uses the 2G / 3G network. Voice communication is performed in a circuit switched (Circuit Switched, CS) manner. [0004] CSFB is a single-card single-standby working method...
