Method for comparison and reconstruction of geographic redundancy database

Abstract

The invention relates to a method for comparison and reconstruction of a geographic redundancy database in a wireless communication network. The method comprises the steps that a comparison and arbitration controller module in a data center is in communication connection with at least two local proxy modules related to corresponding local databases and sends audit start orders, and whether the audit start orders are received for the first time or not is judged by each local proxy module; if yes, full detection is conducted; if not, increment detection is conducted; then, fingerprint features of each group are detected and identifiers with different fingerprint features in each local database are stored in a reconstruction list; corresponding user records in each local data are reconstructed through the comparison and arbitration controller module according to the reconstruction list until the fingerprint features of all the user records are identical. According to the method, the requirement for the bandwidth of audit is reduced, the size of data needing to be transmitted is greatly reduced only through detection of the fingerprint features, and therefore the audit speed is increased.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for comparing and reconstructing geographically redundant databases in a wireless communication network. Background technique [0002] In the core network of the mobile communication network, there are many real-time databases that are copied among multiple servers distributed in different places to ensure the consistency of user data in multiple servers. These databases are called geographically redundant databases , mainly including databases in the Home Location Register (HLR), Home Subscriber Server (HSS), Equipment Identification Register (EIR) and / or the database in the Authentication, Authorization and Accounting Server (AAA). The existence of these databases and their contents are very important for mobile communications. [0003] In order to ensure the consistency of the content in these geographically redundant databases, the traditional method is t...

AI Technical Summary

Problems solved by technology

On the one hand, such an audit will have high requirements on the network speed between these geographically redundant databases; on the other hand, due to such a large amount of data, the time for each audit will be quite long

This puts an unbearable burden on limited network resources, and also significantly increases the cost of network deployment for operators
