A network fault recovery method and operator system based on authorization server

Abstract

A network fault recovery method based on an authorization server and an operator system. When a fault occurs in a voice service network, the voice service network terminal monitors the recovery situation of the voice service network in real time; when the voice service network returns to normal, the voice service network The terminal sends a notification message to the authorization server to inform the authorization server that the voice service network is back to normal, and the terminal device on the affected network segment needs to be restored; the authorization server initiates a push message to the push server of the terminal device, so that the push The server sends a voice service re-registration message to the terminal equipment of the corresponding affected network, and the voice service re-registration message will cause the received terminal equipment to re-initiate a registration message to the voice service network, thereby restoring the voice service.

Description

technical field [0001] The invention relates to an authorized server-based network failure recovery method and an operator system. Background technique [0002] After the 4G network is deployed, the voice service and data service of the user terminal are accessed through the same packet domain core network. User terminals such as mobile phones access IMS through voLTE to implement voice services, and EPC access to implement packet data services; after 5G, voNR will continue to be used to implement user voice services, and 5GC access to implement data services. [0003] When 3G and 4G networks coexist, if the voLTE service is abnormal, the user terminal can fall back to the 3G network to achieve voice service continuity. However, after the 3G network is completely withdrawn from the network, the user terminal can only access the IMS through voLTE to realize the user's voice service. In this case, when the user terminal fails to register with the IMS network due to reasons o...

Problems solved by technology

[0005] One is to retry periodically, that is, the terminal device will continue to retry after a period of time; since the recovery of the network side can only be detected, it is difficult to set an appropriate interval. If the interval is set too long, it will It leads to poor user experience. If the interval is set too short, it will consume too much power of the terminal device and shorten its standby time;

[0006] The second is that the user manually restarts the terminal device, or restores the voice service of the terminal device by turning on and off the flight mode of the terminal device; this method requires the user to find that the voice service of the terminal device becomes unavailable, and manually try to restore it. bad experience
