Network selection method and device, mobile terminal and readable storage medium

Abstract

The embodiment of the invention discloses a network selection method and device, a mobile terminal and a storage medium. The method comprises the following steps: acquiring network delay of a WiFi network in a set time slot after the mobile terminal accesses to the WiFi network, computing the average network delay of the WiFi network in the set time slot based on the acquired network delay in theset time slot, and then selecting the corresponding network to access according to the computed average network delay, wherein the network is the VoWiFi network or the VoLTE network. By using the method disclosed by the embodiment of the invention, a problem that the mobile terminal still accesses to the VoWiFi network by mistake since the WiFi network signal is extremely strong but the network state is bad can be avoided, and then the circumstance that the mobile terminal is abnormal in internet surfing or calling after accessing to the VoWiFi network is effectively avoided, and the voice call quality of the mobile terminal is guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of mobile terminals, and in particular to a method, a device, a mobile terminal and a readable storage medium for selecting a network. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is a brand-new multimedia service form, which can meet the newer and more diversified multimedia service requirements of current terminal customers, and IMS supports multiple access and rich Multimedia services have become the core network standard architecture in the all-IP era. [0003] VoLTE, or Voice over LTE (Long Term Evolution, Long Term Evolution), is a voice service based on IMS. It uses IP data transmission technology and does not require 2G / 3G networks. All services are carried on the 4G network, enabling data and voice Services are unified under the same network; VoWiFi, or Voice over WiFi, is a WiFi-based voice service, which is also based on IP data transmission technology. Th...

Problems solved by technology

Although the above method is relatively simple, it also has certain disadvantages. For example, when the WiFi network signal is strong but its network status is not good, if it is connected to a VoWiFi network, it is likely to cause the mobile terminal to appear when surfing the Internet or making calls. abnormal

That is, the current network selection method is difficult to effectively guarantee the voice call quality of mobile terminals
