Problems solved by technology
However, this method is essentially based on the signal strength of LTE and WiFi as the basis for judgment, and has no inhibitory effect on ping-pong reselection and handover in specific scenarios.
Moreover, this method cannot cope with WiFi congestion and cannot guarantee user experience
[0005] Chinese Patent Publication Nos. CN109511141A and CN109769273A respectively propose a method for controlling the reselection from VoWiFi to VOLTE based on RTP packet loss rate and RTP delay jitter, which can solve the problems caused by switching based solely on signal strength in the prior art
However, these methods still have some drawbacks
First of all, for both LTE and WiFi modes, when the RTP packet loss rate is higher than the threshold threshold, it will cause ping-pong switching
Secondly, according to the RTP layer information of the UE, the UE can only judge the downlink situation, and cannot accurately obtain the actual uplink transmission situation of the UE.

The invention provides a VoWiFi and VoLTE voice service switching method and a mobile terminal. The method for switching between VoWiFi and VoLTE voice services of the present invention comprises the following steps: during the voice service period of using one of the WiFi mode and the LTE mode, PS services other than the voice service are carried in the current use mode and another use mode; The first communication index group in the current use mode; evaluate the first link quality according to the first communication index group; obtain the second communication index group in another use mode; evaluate the second communication index group according to the second communication index group link quality; adjusting a switching threshold according to the first link quality and the second link quality; and determining whether to switch from the current usage mode to another usage mode according to the switching threshold.
Description
technical field [0001] The present invention mainly relates to the field of wireless communication, in particular to a method for switching VoWiFi and VoLTE voice services, a mobile terminal and a storage medium. Background technique [0002] In an LTE (Long Term Evolution, long-term evolution) network, UEs (User Equipment, electronic equipment on the user side) can communicate through VoLTE (Voice Over LTE, voice over LTE). Wherein, the VoLTE communication is a voice service based on an LTE system and an IMS (Internet Protocol Multimedia System, Internet Protocol Multimedia System) network. [0003] VoWifi (Voice Over WiFi, voice over Wifi) is a voice service that relies on WiFi for IMS calls. When the set conditions are met, the aforementioned VoLTE mode and VoWiFi mode can be switched seamlessly. [0004] The existing decision algorithms for handover between VoWiFi and VoLTE are all based on LTE or WiFi signal strength. Chinese Patent Publication No. CN109699056A discl...
