Data synchronization method, system and device

Abstract

The invention discloses a data synchronous method, system and apparatus, wherein the data synchronous method comprises: whether the stored data that is checked in the data provides device is updated; when the data update is found, the system will perform data synchronous treatment for corresponding data inquiry devices. The embodiment of the invention has the advantages that the system can realize data synchronous operation between the devices in a simple manner, and meanwhile meet the requirements for long-term and real-time data synchronous demands of the devices.

Description

technical field [0001] The invention relates to the communication field, in particular to a data synchronization method, system and device in a mobile communication system. Background technique [0002] In the network system architecture, the functional roles of devices are gradually divided more clearly. Some devices are dedicated to centralized storage, management and maintenance of user data or business data, while other devices are responsible for specific function execution. In the mobile communication system, devices such as Home Location Register (HLR, Home Location Register), Home Subscriber Server (HSS, Home Subscriber Server), and Subscriber Profile Repository (SPR, Subscriber Profile Repository) are centralized storage, management and maintenance of relevant data. The role of the central database is used to provide data to specific function execution equipment; while the mobile switching center (MSC, MobileSwitching Center), application server (AS, Application Ser...

AI Technical Summary

Problems solved by technology

[0015] First of all, the implementation of the subscription-notification mechanism needs to maintain a session between the data providing device and the data query device, which adds additional processing procedures for non-session-related data and increases the complexity of synchronously updating non-session-related data;

[0016] Secondly, the subscription-notification mechanism is effective during the entire session, and is automatically revoked when the session is terminated, which cannot meet the long-term and real-time data synchronization needs between devices.
