METHOD AND SYSTEM IN TELECOMMUNICATIONS NETWORK FIELD OF THE INVENTION

The present invention relates to telecommunications. More particularly, the present invention relates to a method and system for forming interfaces between network elements and for decentralizing control of network elements.

BACKGROUND OF THE INVENTION

10 Mobile Subscriber (MSN)

Network) consists of several different network components that control and control the operation of a mobile network. In order to serve mobile network customers, certain subscriber data must be stored in a number of databases. Subscriber information is usually stored in the Home Location Register (HLR). Subscriber data includes subscriber service data and mobility management data.

In the past, there have been ideas that the 20 service operators could purchase the necessary components for use in a mobile network, such as GSM (Global System for Mobile Communications), such as a MSC, Mobile

Switching Center), a home location register, and a Service Control Point (SCP) for an IN (,.ί.ί 25 Intelligent Network). In this case, the operator could act as a service operator under similar roaming agreements, both internationally and possibly also nationally.

30 If the service provider follows the above procedures, it is not dependent on any particular network operator. On the other hand, mobile. Ownership of network and intelligent network components requires in-depth knowledge and knowledge of the GSM-35 system or other mobile communication system and its maintenance. In addition, the standardization of interfaces between network components is very difficult. Providing open interfaces can also pose a security risk to your network operator.

It is an object of the present invention to eliminate or at least significantly alleviate the above disadvantages.

In particular, it is an object of the invention to provide a new type of method and system by which a service operator-network operator interface can be implemented without the service operator owning network components of a mobile network. The service operator only maintains easily manageable databases.

As regards the characteristic features of the present invention, reference is made to the claims.

SUMMARY OF THE INVENTION

The method of the invention aims at decentralizing the management of network components. In the method 20, a first and a second non-mobile and intelligent database are created, in which · '. * ·: The relevant subscriber information is stored. The management of the first and second external databases is separated from the management of the mobile network and the intelligent network. The first database of the Edel-25 is connected to the mobile communication network and the second database is connected to the intelligent network.

The present invention provides services to mobile subscribers through the creation of databases using existing mobile and intelligent networks.

The mobile communication network 1 includes means 3 for updating the first database DB1 and means 4 for performing read operations from the first database DB1.

The intelligent network 2 includes means 5 for updating a second database DB2 and means 6 for performing read operations from a second database DB2.

External databases DB1 and DB2 include 15 means 13 and 14 for storing and retrieving information. Further, the system includes means 7 for connecting the first database DB1 to the mobile communication network 1 and means 8 for connecting the second database DB2 to the intelligent network 2. The interface 15 between the mobile communication network 1 and the intelligent 20 network 2 is formed using a real time database protocol.

The control point SCP of the intelligent network 2 is coupled to the second database SDP and includes means 10 and 12 for performing write and read operations on the second database SDP. In this example, the control point SCP receives the information it needs from another database SDP. The interface 15 between the first database HLR-DB and the home location register HLR 10, and the interface 15 between the second database SDP and the control point SCP of the intelligent network 2 can be formed using a real-time database protocol.
