METHOD FOR ACCESSING MAGNANIMITY DATA OF INTELLIGENT NETWORK SERVICE DATABASE AND SYSTEM AND DEVICE THEREOF

A system, device and method for accessing massive data in intelligent network service databases are provided. The system includes a SCF entity and a SDF entity. The SDF entity provides multiple service databases for storing massive service data of the same intelligent network system. The SCF entity connects with the multiple service databases; when a service establishes service data of a user, the SCF entity selects a specific service database according to service information of the user and a service key in accordance with a database reset policy, and stores the service data in the specific service database; when the user uses the service, the SCF entity associates with and locates the specific service database according to the service information of the user by using a method corresponding to the database reset policy; and the SCF entity interacts with the service database to accomplish the service function. The above function is implemented by a corresponding device in the SCF entity. The present invention utilizes distributed service databases to dispersedly store massive service data so as to share the access pressure, and thus the access performance of the service databases is improved.
