Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] At present, the switching conditions considered in the switching schemes of VoLTE / VoNR and VoWiFi are relatively simple. Generally, only the threshold (Threshold) and the timer (Timer) are used to judge whether switching is required, but the Threshold is only a fixed value, which can easily lead to Ping pong switching (ping pong is a means of data caching, and the efficiency of data transmission can be improved through ping pong operation). In addition, this handover solution is only suitable for handover scenarios of Wi-Fi and LTE / NR edge mobility, because when the LT / NR poor sig...

Abstract

The invention discloses a network call switching method and system and a mobile terminal, and the method comprises the steps: when the mobile terminal carries out a voice call, detecting and judging the current optimal setting of a user, wherein the optimal setting comprises mobile network priority and WiFi network priority; if the priority setting is mobile network priority, checking whether a mobile network signal is lower than a first preset signal threshold value, and if yes, switching the VoLTE or VoNR call to the VoWiFi call; and if the priority setting is the WiFi network priority, checking whether a WiFi network signal is lower than a second preset signal threshold value, and if so, switching the VoWiFi call to the VoLTE or VoNR call. According to the invention, the network with better call quality is selected according to the signal condition, the call quality is improved, and the probability of occurrence of call quality problems can be reduced.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a network call switching method, system, mobile terminal and computer-readable storage medium. Background technique [0002] From 3G, 4G to 5G, the speed of mobile Internet access is getting faster and faster. But for telecom operators, because the frequency bands used are getting higher and higher, the difficulty of network coverage increases, which is a difficult problem they have to face. In particular, indoor deep coverage is more difficult, which will bring inconvenience to users in indoor data Internet access and voice calls. WiFi is regarded as the "key" to open the "door lock". As long as there is WiFi indoors, even if the mobile signal coverage is poor, Internet access can be easily realized, and WiFi can also meet the needs of voice calls in indoor scenarios. [0003] In foreign countries, VoWiFi (Voice over WiFi) or WiFi Calling service has been...
