5G independent networking terminal registration method and system, terminal and storage medium

Abstract

The invention discloses a 5G independent networking terminal registration method and system, a terminal and a storage medium, and the method comprises the steps: when a 5G network is registered, if a network end does not support VORR and EPS fallback, after the network end refuses to register the 5G network, 4G network registration is initiated in LTE; when the data service is initiated, a 5G network registration request is re-initiated to the network end, the registration request carries priority information, and PDN connection is initiated to the network end; and after the data service is finished, initiating a 4G network registration request in the LTE again, and switching the 5G network to the 4G network to perform the voice service. According to the invention, after the 5G independent networking registration of the terminal is rejected, when the data service exists, the registration request is initiated on the 5G network again, so that the problems that the terminal can only reside in the 4G network, and the terminal cannot reside in the 5G network, so that the 5G data service cannot be acquired and the 5G high-speed internet cannot be enjoyed are solved, the terminal can preferentially access the 5G NR network, and the user experience is improved. Therefore, the terminal can use the data service of the 5G network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a 5G independent networking terminal registration method, system, terminal and storage medium. Background technique [0002] The commercial use of 5G has brought waves of hot spots. 5G relies on a new wireless connection technology with low latency, high throughput, and large connections. It separates the control plane and the user plane to provide network efficiency. It is bound to enter the core of our lives. It changes life in every aspect; when everyone is still intoxicated by the joy of seeing the 5G logo on the mobile phone and experiencing the high-speed experience and enjoyment brought by 5G at the earliest, a direct problem faced by the majority of mobile communication users has surfaced. How does 5G provide What about voice calls? [0003] At present, 5G technology has been widely used on mobile terminals, and operators have also begun to deploy 5G SA (S...

AI Technical Summary

Problems solved by technology

[0006] The main purpose of the present invention is to provide a 5G independent networking terminal registration method, system, terminal and storage medium. When the terminal uses the data service, it initiates a service request centered on the data service, aiming to solve the problems of existing technologies in 5GVoNR or 5GVoNR. When the Volte network deployment is not perfect, the terminal cannot use the 5G network problem
