Embodiment Construction

[0049] 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 only some, not all, embodiments of the present invention. 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.

[0050] The embodiment of the present invention discloses an IMS registration method, which is applied to a user terminal. Refer to figure 1 As shown, the method includes:

[0051] Step S11: Determine whether the current network environment is an environment covered by a 5G network.

[0052] Step S12: If yes, perform 5G network registration, and then switch the working network to the 4G network through the integrated core network obtained through the integrate...

Abstract

The application discloses an IMS (multimedia subsystem) registration and voice business providing method, a system, a device and a storage medium. The IMS registration method includes steps of carrying out 5G network registration if current network environment is the environment covered by a 5G network; then switching the working network to a 4G through a fusion core network acquired through fusing and allocating a 4G core network and a 5G core network so as to keep the IP address unchanged; completing the IMS registration under the 4G network, and carrying out the voice business after switching an IMS registered user terminal from the 5G network to the 4G network. The voice business providing method includes steps of automatically switching the working network to 4G network through the fusion core network acquired through fusing and allocating the 4G core network and the 5G core network when it is monitored that the current state is the to-be-carried voice business state and the current working network is 5G network, and completing corresponding voice business. The IMS registration method and the voice business providing method are combined to effectively realize the purpose of providing the voice business for the 5G network terminal.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an IMS registration method, system, device and computer-readable storage medium, and a voice service providing method, system, device and computer-readable storage medium. Background technique [0002] With the continuous development of communication technology, 5G network, as the fifth generation mobile communication network, has a maximum theoretical transmission speed of tens of Gb per second, which is hundreds of times faster than the transmission speed of 4G network. Can be downloaded within 1 second. It can be seen that the wireless frequencies currently used by the 5G network are all very high. According to the principle that the higher the frequency, the weaker the ability to penetrate obstacles and the smaller the coverage area, it is impossible for the 5G network to provide full coverage in the short term. From this point of view, for a long time, 4G network...
