Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a database management method and apparatus for a service management system and a service control point in an intelligent network system.

[0002]

2. Description of the Related Art In an intelligent network system, a service management system (Service Ma) that manages and operates a network database.
An SMS database held on the management system (hereinafter referred to as SMS) and a service control point (Service) that manages call processing.
The SCP database held on the Control Point (hereinafter referred to as SCP) may be provided as a database of a different format from the viewpoint that the SMS database is easy to maintain data and the SCP database is high in data access speed. . At this time, there is no function for synchronizing the contents of databases of different formats held on different nodes by real-time processing. In CCITT's recommendation of intelligent networks, the definition of words and the outline of roles are described, but there is no description of a concrete implementation method like the present invention.

[0003]

The data on each node existing in the network needs to be updated on each node, and when there are multiple nodes having the same data, the same data is applied to each node. Changes have to be made. Therefore, it takes a lot of time to manage and operate a large amount of data.

An object of the present invention is to make it possible to centrally manage a database on a network in an intelligent network system composed of one SMS node and a plurality of SCP nodes, facilitating maintenance and operation of a large amount of data. It is an object of the present invention to provide a database management method and device for an intelligent network system that can be used.

[0005]

SUMMARY OF THE INVENTION The present invention is an intelligent system composed of a service management system for holding a database having information on the entire network and a plurality of service control systems for holding a database for managing call processing. In the database management method of the network system, the database is updated in response to the update request to the database on the service management system, the update request data is converted into the database format of the service control system,
Real-time synchronization between the service management system and databases on all service control systems is performed by requesting data update to the databases on all service control systems and managing the database update results on each service control system. It is characterized by guarantee.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a system configuration diagram showing an embodiment of the present invention, which manages an SMS 21 holding an SMS database 22 having information on the entire network, an access terminal 11 for accessing the SMS 21, and call processing. SCP database 32, 42, 52 for
Are respectively held by SCP 31, 41, 51. Further, FIG. 1 also shows a processing flow of real-time synchronization management of a database according to the present invention.

Access terminal 11 connected to SMS 21
When a data update request (61) for the intelligent network is generated from the data update management means 24 on the SMS, the data update management means 24 receives the update request data, confirms the normality of the data, and then updates the update request data to the database synchronization management means 25.
To (62). In the database synchronization management means 25,
After updating (63) the SMS database 22 corresponding to the update request data, the transaction management table 23
In (4), it is managed as a data updating state, and the update request data is passed to the data format conversion means 26 (65). The data format conversion means 26 converts the update request data from the SMS database format to SCP.
In order to convert to the database format and transfer the data to all the SCPs existing on the network, the internode communication means 27 is requested to transmit the data (6
6). The inter-node communication means 27 transfers the update request data to all the SCP nodes recognized in the system (67, 68, 69).

In each SCP node, the inter-node communication means 33, 43, 53 on each node receives the data transmission from the inter-node communication means 27 of SMS, and the SCP DB updating means 34, 44 on each node. , 54 is requested to update the database on the SCP (3
5,45,55). SCP DB updating means 34, 44,
54 is the SCP database 3 on its own node
After updating the data of 2, 42, 52 (36, 46, 56), the update result response is transmitted to the SMS node to the inter-node communication means on its own node (37,
47, 57).

Inter-node communication means 33, 4 on the SCP
3, 53 send the update result response of the SCP DB to the SMS (38, 48, 58), and the SM
The inter-node communication means 27 of S is the SCP from all the SCPs.
The DB update result response message is received, and the message is passed to the database state management means 28 (70),
The database status management means 28 analyzes the update result response of the SCP DB, and when the update results from all the SCPs are normally completed, the data update status of the transaction management table 23 set by the database synchronization management means 25 is released ( 71) By doing so, the update of the SMS database and the database on all SCPs is normally performed,
It is assumed to be synchronized.

Also, all or some SCPs
When the update result from the above is an error, the database state management means 28 registers that an error has occurred in a specific SCP with respect to the update request data in the transaction management table (71). Then, when the retransmission management means 29, which periodically monitors the transaction management table (72), detects an error in the transaction management table, a specific S is detected according to the error type.
The update request data is resent to the CP a specified number of times (73). If an error remains after the specified number of times of resending, it is determined that automatic recovery is impossible, and an alarm is generated to request recovery by a maintenance person.

[0011]

As described above, the present invention manages and operates a database in an SMS node which exists only in one place on the network, and automatically transfers the database to all the SCP nodes for synchronization. For,
Maintenance of databases on multiple SCPs is not required, and management, operation, and maintenance of databases for the entire network are facilitated, and data is transferred in real time to all SCP nodes, so that service provision is possible. This has the effect of speeding up.
