Patent Images
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.

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.

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. - View Dependent Claims (7, 8, 16)

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. - View Dependent Claims (17)

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. - View Dependent Claims (11, 12, 13, 14)

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.
