Abstract

A communication system and a method and a server for a communication system is disclosed. The communication system comprises communication means for providing communication media for a plurality of user equipment, a storage entity (21) adapted to store information that associates with at least one of said user equipment, and at least one service provision entity (28) adapted to serve a client based on information stored in said storage entity. The storage entity (21) is arranged to receive information associated with the user equipment from other entities (22, 23) and to associate said received information with a respective user equipment.

Claims

1. A communication system comprising:

communication means for providing communication media for a plurality of user equipment;

a storage entity adapted to store information that associates with the status of at least one of said user equipment, wherein the storage entity is arranged to receive information from other entities and to associate said received information with a respective user equipment; and

at least one service provision entity adapted to serve a client based on information stored in said storage entity.

2. A communication system as claimed in claim 1, wherein the status information comprises the status of the user equipment.

3. A communication system as claimed in claim 1, wherein the status information comprises information about the state of a communication session.

4. A communication system as claimed in any preceding claim, wherein the status information comprises an indication if the user equipment has an active connection at a given moment.

5. A communication system as claimed in any preceding claim, wherein the information stored in the storage entity comprises information associated with the geographical location of the user equipment.

6. A communication system as claimed in any preceding claim, wherein said other entities are adapted to provide at least ore of the following functions:

home subscriber server;

call state control;

location service.

7. A communication system as claimed in any preceding claim, wherein the update of the information stored in the storage entity is arranged to occur dynamically.

8. A communication system as claimed in, any preceding claim, wherein the service provision entity comprises an application server.

9. A communication system as claimed in any preceding claim, wherein at least one service provision entity is adapted to provide presence information.

10. A communication system as claimed in any preceding claim, wherein at least one service provision entity is adapted to provide an instant messaging service.

11. A communication system as claimed in any preceding claim, wherein at least one service provision entity is adapted to provide a rich call service.

12. A communication system as claimed in any preceding claim, wherein the interface between the storage entity and the service provision entity is based on protocol the service provision entity uses for communication with at least one other entity.

13. A communication system as claimed in any preceding claim, wherein communication between the storage entity and the service entity is protected by a security function.

14. A communication system as claimed in any preceding claim, wherein a user equipment may have more than session at the same time and wherein at least two of said sessions are controlled by different network entities.

15. A communication system as claimed in any preceding claim, wherein the storage entity is adapted to receive information associated with the status of a user equipment from at least two different sources.

16. A communication system as claimed in any preceding claim, wherein the client is one of the user equipment.

17. A communication system as claimed in any preceding claim, wherein the service provision entity is located in a first network and the client is located in a second network.

18. A communication system as claimed in any preceding claim, wherein the storage entity and the service provision entity belong to different networks.

19. A communication system as claimed in any preceding claim, wherein at least one of the user equipment comprises a mobile station.

21. A server means as claimed in claim 19, wherein the server means is adapted to provide status information about user equipment based on information received from a plurality of elements of the communication system.

20. A server means for a communication system, said server means comprising:

interface means for receiving information associated with user equipment adapted for communication via the communication system from at least one element of the communication system;

means for dynamically associating the received information with corresponding user equipment;

means for storing the information such that the information can be retrieved based on indication of a particular user equipment; and

interface means for connection between the server means and at least one service entity, whereby the service entity serves clients based on information from the server means.

22. A method in a communication system, said communication system providing communication media for a plurality of user equipment, the method comprising the steps of:

generating information associated with a user equipment in an entity of the communication system;

communicating said information to a storage entity;

at the storage entity, receiving and associating said information with the user equipment; and

providing information that associates with the user equipment to a service provision entity, whereby the service provision entity is enabled to serve clients based on said information from said storage entity. A server means for a communication system
