Abstract

The invention proposes a method for controlling a network, wherein the networks offers services to registered users, the method comprising the steps of receiving (A1) a service request from network device (UE) of a user, checking whether the user is registered or not, and if the user is not registered, generating a response message including a warn information and sending (A2; B3 to B4) the response message to the network device (UE) of the user. The invention also proposes a corresponding network device. In this way, a user is informed that he has to register before he can obtain any services from the network.

Claims

1. A method for controlling a network, wherein the networks offers services to registered users, the method comprising the steps of

receiving a service request from network device of a user,

checking whether the user is registered or not, and

if the user is not registered, generating a response message including a warn information and sending the response message to the network device of the user.

2. The method according to claim 1, wherein the response message is a SIP (Session Initiation Protocol) response.

3. The method according to claim 2, wherein the SIP response is a 403 Forbidden response.

4. The method according to claim 1, wherein the warn information comprises a warn-text.

5. The method according to claim 4, wherein the warn-text is a predefined warn-text.

6. The method according to claim 1, wherein the warn information comprises a predefined warn-code.

7. The method according to claim 1, further comprising the step of triggering (A3;

B5) an automatic registration in the network device of the user.

8. The method according to claim 1, further comprising the step of checking whether the user had a valid registration before or not,

wherein in case the user had no valid registration before, in the generating step, the information that a registration is required is inserted into the warn information.

9. The method according to claim 1, further comprising the steps of

checking whether the user had a valid registration before or not and whether a de-registration of the user had been performed, and

wherein in case the user had a valid registration before and a de-registration of the user had been performed, in the generating step, the information that a re-registration is required is inserted into the warn information.

10. The method according to claim 8, wherein the network is a third generation network, and wherein the generating step is performed in a proxy call state control function (P-CSCF).

11. The method according to claim 9, wherein the network is a third generation network, and wherein the generating step is performed in a serving call state control function (S-CSCF).

20. The device according to claim 1, wherein the network is a third generation network, and wherein the network control device is a proxy call state control function (P-CSCF).

21. The device according to claim 1 or 19, wherein the network is a third generation network, and wherein the inserting step is performed in a serving call state control function (S-CSCF).

12. A network control device for controlling a network, wherein the networks offers services to registered users, the device is adapted

to receive a service request, to check whether a user requesting the service is registered or not, and generate a response message containing a warn information to the user, in case the user is not registered.

13. The device according to claim 12, wherein the response message is a SIP (Session Initiation Protocol) response.

14. The device according to claim 13, wherein the SIP response is a 403 Forbidden response.

15. The device according to claim 12, wherein the warn information comprises a warn-text.

16. The device according to claim 15, wherein the warn-text is a predefined warn-text.

17. The device according to claim 12, wherein the warn information comprises a predefined warn-code.

18. The device according to claim 12, wherein the device is adapted to check whether the user had a valid registration before or not, and, in case the user had no valid registration before, to insert into the warn information the information that a registration is required.

19. The device according to claim 12, wherein the device is adapted to check whether the user had a valid registration before or not and to check whether a de-registration of the user had been performed, and to insert into the warn information the information that a re-registration is required in case the user had a valid registration before and a de-registration of the user had been performed.

22. A network system, comprising a network control device according to claim 12, further comprising a network device, wherein the network device is adapted to perform an automatic registration in reaction to the response message.

23. A network device being connectable to a network, the network offering services to registered users, wherein the device is adapted to receive a message and to perform an automatic registration to the network in case the message contains a predetermined warn information.

24. The network device according to claim 23, wherein the warn information contains a warn-code.

25. The network device according to claim 23, wherein the warn information contains a warn-text.
