Abstract

The present invention relates generally to an arrangement for extending service support in a communications system, especially a telecommunications system, said system comprising distributed hardware and software components which interact in order to provide services to one or more users, and the improvement is primarily implemented by introducing in said system an interface which also provides services to mobility-based applications. More specifically there is according to the present invention introduced a service interface for mobility-based applications for thereby providing the applications in question with location information.

Claims

1. Arrangement for extending service support in a communications system, especially a telecommunications system, said system comprising distributed components which interact in order to provide services to one or more users,

characterized in introducing in said system an interface which also provides services to mobility-based applications, said service interface comprises an object called Informer, the basic operations of the Informer object consist of operation to query the location of one user, operation to query locations, i.e., the Network access point (NAP) of a group of users, operation to query the terminal currently used by one user, operation to query the terminals currently used by a group of users, operation to query the location of a terminal and operation to query the locations of a group of terminals, which information is obtained in cooperation with objects of the communication system in question through agent technique.

2. Arrangement as claimed in claim 1, characterized in that the operations of the Informer object in addition comprises operation to get history data of a user and operation to get history operation of a terminal.

3. Arrangement as claimed in claim 1, characterized in that all users and terminals whose location should be available to the applications is registered by the Informer object.

4. Arrangement as claimed in claim 3, characterized in that said location information comprises already available information being held by said communications system.

5. Arrangement as claimed in claim 4, characterized in that said Informer object, which is a computation object, comprises basic operations which can be invoked from any application.

6. Arrangement as claimed in claim 1, characterized in that said interface and the support related thereto, are introduced in any open distributing processing (ODP) system or any generic mobility system (GMS), and that said Informer object is adapted to co-operate with other objects in said systems.

7. Arrangement as claimed in claim 6, characterized in that there is defined one user agent for each user and one terminal agent for each terminal.
