Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039]The basic idea of ​​the present invention is: through the standard interface request message in the Diameter protocol of the new generation AAA (authentication, authorization, accounting) protocol, such as Cx, Sh interface request message, to realize the main production HSS and disaster recovery in the IMS system Data synchronization between backup HSSs has good compatibility and is easy to implement.

[0040] Fig. 2 shows the structure of the data synchronization system between the disaster recovery HSSs in the present invention, which is applied to the IMS system, including the production m...

Abstract

The invention discloses a data synchronizing method and system of hazard-containing imputed user server HSS, which comprises the following parts: main HSS, prepared HSS, relative net element IMS system of main HSS and the prepared HSS. The method comprises the following steps: the relative net element transmits standard interface request information to the main HSS through Diameter protocol, which requires modifying the reserved user data of main HSS to modify the local user data through standard interface request information, which transmits the standard interface request information to the prepared HSS through Diameter protocol; the prepared HSS modifies the local user data according to the standard interface request information. The invention has good compatibility, simple elementary and convenient realization, which is fit for HSS hazard-containing duplication of different manufacturers.

Description

technical field [0001] The present invention relates to the technical field of IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), in particular to a data synchronization method and system between disaster recovery HSS (Home Subscriber Server, Home Subscriber Server). Background technique [0002] In traditional disaster recovery between communication network elements, such as disaster recovery between HLRs (Home Location Registers), it is necessary to consider how to ensure the consistency of user data between the production master machine and the disaster recovery standby machine in real time, so as to facilitate When the production main machine suddenly fails and goes down, the business can be immediately switched to the disaster recovery standby machine for correct processing. [0003] The third-generation mobile communication will evolve to an all-IP-based network architecture. 3GPP first proposed the IMS network architecture, which can become the basis for future m...
