Data storage system in communication network and information processing method

Abstract

The invention discloses a data storage system in a communication network used for realizing distributed storage of data. The system comprises front-end nodes, storage nodes, super nodes, management nodes, and calculating units which are positioned in the front-end nodes, the super nodes or the storage nodes, and are used for calculating first data GUID according to preset fixed offset to obtain second data GUID, determining a super node of which the node identification is most close to the second data GUID according to link chain information acquired on the management nodes and the second data GUID, and forwarding an insertion request carrying the second data GUID, the data information and a backup flag to the determined super node. The invention also discloses a method for processing information by the system.

Description

technical field [0001] The invention relates to the communication field, in particular to a data storage system and an information processing method in a communication network. Background technique [0002] Home Subscriber Server (HSS) is a centralized user database system that stores user authentication information, user business information, user roaming information, information about which core network will serve the user, and authorization functions (Authentication, Authorization and Accounting, AAA) and so on. HSS is also used to record the user's original billing data and provide it to the sorting system for billing. [0003] The current IP Multimedia Subsystem (IP Multimedia System, IMS) architecture adopts a centralized storage structure. An HSS usually stores information of more than one million users, and must support 1000 queries and 100 modifications per second. The performance requirements of the HSS are relatively high, so that the cost of the HSS is usually ...

AI Technical Summary

Problems solved by technology

The performance requirements of HSS are high, so the cost of HSS is usually relatively high

Moreover, in order to ensure 99.999% reliability of the carrier-class system, HSS uses at least one host and one backup. The cost is doubled, and if the standby machine is not at the same physical address as the main machine, there is a delay when the standby machine starts after the main machine fails, and if the standby machine is at the same physical address as the main machine, it is also very slow when the main machine fails possible failure

Similarly, for the centralized storage method of HSS, the storage performance of the IMS architecture can only be improved by improving the hardware level. However, it is difficult to improve the hardware level, and it is not convenient for the network topology, so it is difficult to keep up with the rapid growth. user needs in

[0004] At the same time, the solution required by the current IMS architecture distinguishes the roaming location and the home location. One HSS only provides user data for the local S-CSCF. When a user roams to other regions, it needs to first register with the VLR at the roaming location. Then obtain user information from the HSS at the home location through the VLR, the implementation process is cumbersome and requires more signaling procedures
