Problems solved by technology
This method causes process redundancy and affects data access efficiency
The impact on core data such as HLR and HSS is particularly obvious, which will directly affect the time for call establishment, thereby affecting user experience
In addition, as a network element that must pass through data access, the performance of GUP devices will also become the bottleneck of the network
[0007] (2) The maintenance of GUP is difficult
Changes in any data source (including data changes and equipment changes) will cause changes to the GUP, and real-time maintenance of the GUP is difficult to guarantee
[0008] (3) Poor network disaster recovery capability
Due to the existence of "key points" such as GUP, the overall disaster recovery capability of the network is limited by the reliability of GUP equipment

Embodiment Construction
[0027] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0028] see image 3 , is a schematic diagram of the architecture of the user data storage system provided by the embodiment of the present invention. As shown in the figure, the architecture includes user data centers (UDRs), data federation nodes, data aggregation nodes, and data storage nodes, where data storage nodes can be represented by DS (data source), and DS is not a specific name, but a reference to data The source generally refers to a user whose data may (often) exist in multiple DSs. In the actual network architecture, there are usually multiple DSs, such as image 3 DS1, DS2, DS3 shown in. Among them, the user data center (UDR) is connected to the data federation node, the data federation node is connected to the data aggregation node, the data aggregation node is connected to the data storage node, and the data federation node can also...

The invention discloses a user data storage system and a data access method thereof. In the system, a data storage node is used for storing user data. A data convergent node is used for receiving the user data with relativities in the data storage node, generating and maintaining a mapping relationship view of the user data at the corresponding data storage node, and providing the user data to a data federation node. The data federation node is used for integrating and processing the user data provided by the data convergent node or / and user data stored in the data storage node which is connected with the data federation node, generating and maintaining the mapping relationship view of the user data after being integrated and processed at the corresponding data storage node, and providing the user data after being integrated and processed to a user data center. The user data center is used for storing the user data after being integrated and processed and providing data access service to a front-end device. Employing the user data storage system and the data access method thereof can improve the reliability of data storage systems and the efficiency of data access.
Description
technical field [0001] The invention relates to data storage and processing technology in the communication field, in particular to a user data storage system and a data access method thereof. Background technique [0002] The data storage system in the existing communication core network generally adopts HLR (Home Location Register, Home Location Register) or HSS (Home Subscriber Server, Home Subscriber Server) with centralized storage structure. like figure 1 As shown, it is the mainstream user data storage architecture in the industry at this stage. The data is stored in HLR / HSS centrally, and each front-end equipment (FE) performs data query, maintenance and other processing by accessing HLR / HSS. This data storage architecture is efficient and easy to centralize maintain. However, since all the data is stored in the data center (such as HLR / HSS), the performance and reliability requirements of the data center are relatively high, and the cost of the data center is also...
