Problems solved by technology

However, when the SIP access gateway is restarted due to some reasons, all user information on it will be lost, because the restart is completed in a very short time, and the duration of the timer that triggers the user's re-registration is relatively long (usually 1800 seconds to 3600 seconds), therefore, from the restart of the SIP access gateway to the re-registration of all users, due to the lack of user information, many users will not be able to receive calls, resulting in the failure of users within the jurisdiction of the SIP access gateway. communication
[0005] Therefore, it is necessary to provide a method to solve the problem of communication failure caused by the restart of this enhanced SIP access gateway

Abstract

Embodiments of the present invention relate to a method for managing user information in a SIP network and a corresponding device. The method includes: after the SIP access gateway restarts, it will start a restart timer; within the validity period of the restart timer, in response to a heartbeat message from the network element, send a heartbeat reply message to the network element, and the reply message includes The restart time of the SIP access gateway is specified. If the difference between the restart time of the SIP access gateway and the current time is less than the interval time of the heartbeat message, the network element sends a registration request to the SIP access gateway, which includes the information of all users represented by the network element User Info. Devices capable of implementing the above methods are also disclosed.

Description

technical field [0001] Embodiments of the present invention generally relate to communication technologies, and more particularly, to devices for managing user information. Background technique [0002] In some remote or sparsely populated places, such as some small villages, some islands, etc., generally only SIP access gateways (Access Gateways) are deployed, and these SIP access gateways communicate with SIP application servers deployed in towns or mainland , these SIP application servers provide voice services or most of the value-added services for users within the jurisdiction of the SIP access gateway. However, once the communication between the SIP access gateway and the SIP application server is interrupted, for example, the optical fiber line is interrupted due to an earthquake, users within the jurisdiction of the SIP access gateway cannot communicate with each other, that is to say, the "local network" under the SIP access gateway "Communications were also inter...
