Problems solved by technology

However, due to some factors, such as abnormal storage data or unsmooth links, HSS will fail to log out users, resulting in inconsistency between HSS and S-CSCF user data, resulting in failure of subsequent services

Embodiment Construction

[0032] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] Please refer to Figure 1. When a user registers, the S-CSCF will send a Server-Assignment-Request (SAR) request to the HSS, and the HSS will save the S-CSCF name after receiving the SAR request. If there are different users from different When the S-CSCF initiates the registration, the HSS will save these S-CSCF names to form an S-CSCF data set. Among them, when the user data is stored on the Home Subscriber Server (HSS) and when the user is registered, the HSS synchronizes the user data to the S-CSCF for storage. When the HSS fails, the HSS can initiate a reset request to the S-CSCF to detect and Maintain data consistency between HSS and S-CSCF.

[0034] In order to solve the protection of the data consistency of the HSS when it fails, the present invention provides a method for realizing the data consistency of the home user ...

Abstract

The present invention discloses a method realizing the data consistency of a home subscriber server. The method is divided into five steps. Firstly, a method realizes the data consistency of the homesubscriber server; secondly, the home subscriber server sends a reset request to a call session control server; thirdly, the call session control server returns a reset response and a registration notification request message to the home subscriber server; fourthly, the home subscriber server sends a registration notification response message to the call session control server; and fifthly, afterreceiving the registration notification response message, the call session control server revises the subscription data of user. Compared with the prior art, by applying the method, a home subscriberserver (HSS) can actively and efficiently detect and correct the abnormality of data, avoid the operation risk caused by the data inconsistency and maintain the stability of services; and meanwhile, the method provides a means of monitoring and correcting the HSS data consistency, reducing the monitoring cost and increasing the quality of management of operators.

Description

Technical field [0001] The invention relates to the field of IP multimedia communication, and in particular to a method for realizing data consistency of a home user server. Background technique [0002] In the traditional IP Multimedia Subsystem (IMS) network, when a user triggers a service, it registers with the Serving Call Session Control Function (S-CSCF), and the S-CSCF initiates a call to the Home Subscriber Server (HSS) Registration notification, HSS stores user location information, and downloads user subscription data to S-CSCF. [0003] The protocol 29.228 specifies the existing data consistency protection method, that is, when the HSS fails to synchronize user data with the S-CSCF or detects that the user initiates an authentication request in a new S-CSCF, the HSS initiates a deregistration to the currently registered S-CSCF. However, when the HSS is due to some factors, such as abnormal storage data or unsuccessful links, it will fail to log off the user, resulting ...
