Description
Technical Field
The present invention relates to the field of private networks for 4G and 5G mobile communications, and in particular, to a method, a system, an electronic device, and a storage medium for enabling a majority of mobile terminals to communicate with high-definition Voice and video of 4G VoLTE (Voice over Long Term Evolution, voice over LTE) and 5G VoNR (Voice over New Radio) commonly used in private networks for mobile communications.
Background
4G mobile communication private network (4G private network for short): and 4G mobile communication networks which are built by factories, mines and the like or are built together with other enterprises and are special for the interior of the enterprises. 5G mobile communication private network (abbreviated as 5G private network): and 5G mobile communication networks which are built by factories, mines and the like or are built together with other enterprises and are special for the enterprises.
In the 2G and 3G ages, the voice service adopts CS (Circuited Switched, circuit switching) technology, that is, a line with exclusive resources needs to be established in the network before the mobile phone calls, and is not removed until the call ends. The ancient early technology has complex networking and low efficiency while consuming resources.
After entering the 4G all IP age, voLTE has emerged to support voice services. VoLTE can encapsulate voice service into IP data packets to be transmitted like express packaging, does not need exclusive resources, and greatly improves network efficiency. More importantly, voLTE has historically improved voice quality and reduced call setup time.
When the time comes to the 5G age, voNR appears, which is an audio and video service solution under the 5G SA network architecture, and can be simply understood as a high-definition video call under the 5G condition, which is equivalent to a 5G upgrade version of a 4GVOLTE call, and mainly pushes the audio and video call from high definition to ultra-definition.
However, the problem with implementing VoLTE and VoNR on private networks is: most mobile terminals may use VoLTE over the 4G public network and VoNR functionality over the 5G public network, but not over the 4G and 5G private networks, although the private network devices are VoLTE or VoNR enabled.
The phenomenon is reflected in the following aspects: (1) After the mobile terminal is started and attached on the 4G private network, a prompt icon VoLTE or HD capable of VoLTE is not displayed on a screen of the mobile terminal or in any prompt area; after the mobile terminal is started and attached on the 5G private network, a prompt icon VoNR capable of VoNR is not displayed on a screen of the mobile terminal or in any prompt area of the mobile terminal (2) a prompt icon (VoLTE or HD) capable of performing VoLTE call functions is displayed on a screen of the 4G mobile terminal or in the prompt area of the mobile terminal, but only VoLTE voice call can be dialed and VoLTE video call can not be dialed; the 5G mobile terminal has a prompt icon (VoNR) displayed on a screen or a prompt area for enabling a VoNR call function, but only a VoNR voice call can be dialed, and a VoNR video call cannot be dialed.
The current solution is: (1) selecting a mobile phone which can be used under a private network. Because a mobile phone cannot know whether to use the VoLTE or VoNR function on the private network in advance, the mobile phone cannot select or has high selection cost in advance; in addition, the selected mobile phone can not necessarily meet various requirements of the private network in subsequent use; (2) by customization. Custom handsets involve handset manufacturers and handset vendors, are complex, inflexible, and costly.
Therefore, it is needed to solve the problem that the 4G private network end does not support the common 4G mobile phone to perform VoLTE call or the 5G private network end does not support the common 5G mobile phone to perform VoNR call, so that the common 4G or 5G mobile terminal can implement VoLTE or VoNR call functions.
