Abstract

A method controls a network, wherein the networks offer services to registered users. The method includes 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. The method can be performed on 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, comprising:

receiving a service request from a network device of a user, wherein said service request is a session initiation protocol invite request;

checking, in a network control device, whether the user is registered to a network or not, by referring to information about a registration status of the user stored in a home subscriber server or in the network control device being a proxy call state control function or a serving call state control function, wherein the network offers services to registered users; and

when the user is not registered, generating a response message including warn information and sending the response message from the network control device to the network device of the user, wherein the response message is a session initiation protocol 403 forbidden message;

wherein the warn information triggers an automatic registration in the network device of the user, in which the network device of the user sends a register request to the network control device automatically when the network device of the user receives the response message.

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

3. The method according to claim 2, wherein the warn-text is a predefined warn-text.

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

5. The method according to claim 1, further comprising:

checking whether the user had a valid registration before or not,

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

15. The method according to claim 1, further comprising:

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

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

6. An apparatus, comprising:

a connector configured to connect to a network, wherein the network is configured to offer services to registered users;

a sender configured to send a service request to the network, wherein said service request is a session initiation protocol invite request;

a receiver configured to receive a response message from the network; and

a controller, wherein in case the response message comprises a predetermined warn information being a session initiation protocol 403 forbidden message indicating that the user is not registered to the network, the warn information triggers an automatic registration in the controller, in which the controller controls the sender to send a register request to the network automatically when the receiver receives the response message.

7. The apparatus according to claim 6, wherein the warn information comprises a warn-code.

8. The apparatus according to claim 6, wherein the warn information comprises a warn-text.

16. The apparatus according to claim 6, further comprising:

a performer configured to perform an automatic registration to the network in case the response message comprises a predetermined warn information indicating that the user is not registered to the network or 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.

9. An apparatus, comprising:

sending means for sending a service request to a network control device of the network, wherein said service recluest is a session initiation protocol invite request;

receiving means for receiving a response message from the network control device; and

controlling means, wherein in case the response message comprises a predetermined warn information being a session initiation protocol 403 forbidden message indicating that the user is not registered to the network, the warn information triggers an automatic registration in the controlling means, in which the controlling means controls the sending means to send a register request to the network automatically when the receiving means receives the response message.

17. The apparatus according to claim 9, further comprising:

performing means for performing an automatic registration to the network in case the response message comprises a predetermined warn information indicating that the user is not registered to the network or 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.

10. A method, comprising:

sending a service request to a network which is configured to offer services to registered users, wherein said service request is a session initiation protocol invite request;

receiving a response message from the network; and

wherein in case the response message comprises a predetermined warn information being a session initiation protocol 403 forbidden message indicating that the user is not registered to the network, the warn information triggers an automatic registration, in which a register request is sent to the network automatically when the response message is received.

11. The method according to claim 10, wherein the response message is a session initiation protocol response.

12. The method according to claim 11, wherein the session initiation protocol response is a 403 forbidden response.

13. The method according to claim 10, wherein the warn information comprises a warn-text.

14. The method according to claim 10, wherein the warn information comprises a predefined warn-code.

18. A computer program embodied on a computer storage readable medium, the computer program being configured to control a processor to perform:

connecting to a network, wherein the network is configured to offer services to registered users;

sending a service request to the network, wherein said service request is a session initiation protocol invite request;

receiving a response message from the network;

in case the response message comprises a predetermined warn information being a session initiation protocol 403 forbidden message indicating that the user is not registered to the network, triggering an automatic registration in a controller;

controlling a sender to send a register request to the network automatically when the response message is received.

19. An apparatus comprising:

a receiver configured to receive a service request from a network device of a user, wherein said service request is a session initiation protocol invite request;

a controller configured to check, whether the user is registered to a network or not, by referring to information about a registration status of the user stored in a home subscriber server or in the apparatus being a proxy call state control function or a serving call state control function, wherein the network offers services to registered users; and

the controller being configured, to, when the user is not registered, generate a response message including warn information and sending the response message from the network control device to the network device of the user, wherein the response message is a session initiation protocol 403 forbidden message;

wherein the warn information triggers an automatic registration in the network device of the user, in which the network device of the user sends a register request to the network control device automatically when the network device of the user receives the response message.
