Problems solved by technology

[0003] In related roaming technical solutions, if both the home operator and the visited operator have enabled Voice over new radio (VoNR) on their own networks, when the UE moves into the roaming area, there will be cross-operator VoNR switching, resulting in the use of the VoNR service of the visited operator in the visited place, which conflicts with the requirements of the home operator

Abstract

The invention relates to a voice fallback method and related equipment, and relates to the technical field of computers. The method executed by an AMF network element comprises: acquiring a mobility analysis result of a UE, a voice stream identifier of the UE and location information of the UE, the UE initiating or performing a VORR service in a non-roaming area; generating an RFSP index value of voice fallback according to the mobility analysis result of the UE, the voice stream identifier of the UE and the position information of the UE; and sending the RFSP index value of voice fallback to a 5G base station accessed by the UE, so that the 5G base station notifies the UE to initiate EPS fallback. According to the method, the problem that cross-operator VORR switching conflicts with the requirement of an affiliated operator due to a related roaming technical scheme can be avoided, and the continuity and service experience of a user voice service can also be guaranteed.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a voice fallback method, a network element with access and mobility management functions, a 5G base station, electronic equipment, and a computer-readable storage medium. Background technique [0002] For the demand scenario of 5G standalone (Standalone, SA) core network roaming across different networks, some home operators require 5G voice in the roaming area to adopt the Evolved Packet System (EPS) fallback solution, that is, the user equipment ( User Equipment, UE) falls back to 4G when initiating an IP Multimedia Subsystem (IP Multiple Subsystem, IMS) call on the 5G network, and implements voice services through the 4G network. [0003] In related roaming technical solutions, if both the home operator and the visited operator have enabled Voice over new radio (VoNR) on their own networks, when the UE moves into the roaming area, there will be cross-operator V...
