A volte user registration method, mme and terminal

Abstract

Embodiments of the present invention provide a VoLTE user registration method, MME and terminal. The method includes: receiving a service registration request sent by a terminal, and the service registration request includes a registration flag; according to the registration flag, if it is judged that PS service registration and VoLTE service registration are simultaneously initiated, then the SGW sends the simultaneous network establishment data to the PGW APN default bearer and IMS APN default bearer request, so that PGW establishes corresponding network data APN default bearer and IMS APN default bearer; according to the established network data APN default bearer and IMS APN default bearer, PS service registration and the VoLTE service registration. The MME is configured to perform the method. In the embodiment of the present invention, the terminal sends a service registration request carrying a registration flag bit to the MME, and simultaneously performs PS service registration and VoLTE service registration, thereby improving service registration efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a VoLTE user registration method and system. Background technique [0002] With the continuous development of LTE network and the continuous increase of VoLTE users, mobile communication users' demand for VoLTE high-definition voice and video services is constantly enriched, and the convergence of mobile communication services is serious. Faced with the increasing user demand for VoLTE services, VoLTE users can get more High-quality network experience, especially high-quality experience on high-definition voice and video calls is an important task at present. [0003] In the prior art, a VoLTE voice service implementation method is that the terminal determines that the current serving cell supports the long-term evolution voice VoLTE service, determines that the signal strength of the LTE network of the current serving cell meets the VoLTE serv...

AI Technical Summary

Problems solved by technology

When a terminal supporting VoLTE service starts the network and VoLTE service at the same time, there are two initial registrations and periodic registrations of PS service and VoLTE service. Synchronization, which leads to the need to initiate a registration process for PS services and a registration process for VoLTE services during periodic registration, so the efficiency of service registration is very low
