Claims
- 1. A method for determining an address of a network node in a network where the subscriber currently locates in a mobile communication system, the method comprising:
maintaining in the mobile communication system subscriber's location information; and determining on the basis of the subscriber's location information the address of the network node.
- 2. The method of claim 1, further comprising:
receiving in the mobile communication system a message from subscriber's user equipment, the message indicating the address of the network node; checking whether or not the address which the message indicated corresponds to the address determined on the basis of the location information; and if they do not correspond to each other, using the address determined on the basis of the location information.
- 3. The method of claim 1, further comprising:
receiving in the mobile communication system a message from subscriber's user equipment, the message including subscriber's location information; checking whether or not the location information in the message corresponds to the location information maintained in the system; and using the maintained location information if it does not correspond to the location information in the message.
- 4. A method for determining a network node address in a mobile communication system, the network node being in a location network of a subscriber, the method comprising:
receiving in the mobile communication system a message from subscriber's user equipment, the message indicating subscriber's location information; and determining on the basis of the subscriber's location information the address of the network node.
- 5. The method of claim 4, wherein the message contains a global cell identifier which indicates the subscriber's location information.
- 6. A method for transmitting, to subscriber's user equipment, information required for a service in a mobile communication system, the method comprising:
authenticating the subscriber; and transmitting to the user equipment at least part of the information during the subscriber authentication.
- 7. The method of claim 6, wherein the authentication is application level authentication.
- 8. The method of claim 6, wherein the service is certificate issuance service and the user equipment utilizes said part of the information during a certificate issuance procedure in a visited network.
- 9. The method of claim 6, wherein said part of the information is location network specific information.
- 10. The method of claim 6, wherein said part of the information comprises at least an address of a network node via which the service is provided.
- 11. The method of claim 6, wherein said part of the information comprises at least a public key required for the service.
- 12. The method of claim 6, wherein said part of the information comprises at least an indication of the protocol required for the service.
- 13. The method of claim 6, wherein the service is certificate issuance service and said part of the information comprises at least an address of a network node via which the service is provided and the method further comprising transmitting from the user equipment a certificate request to the network node.
- 14. A method for transmitting to subscriber's user equipment information required for a service in a mobile communication system, the method comprising:
authenticating the subscriber; receiving a message relating to the service; and transmitting to the user equipment in a reply message at least part of the information in response to the received message.
- 15. The method of claim 14, wherein the message and the reply message are transmitted in an integrity protected channel.
- 16. The method of claim 15, wherein the message is transmitted from the user equipment, the message is requesting an address of a network node via which the service is provided and said part of the information comprises at least the requested address..
- 17. The method of claim 16, further comprising transmitting from the user equipment a certificate request to the network node.
- 18. The method of claim 14, wherein said part of the information comprises at least a public key required for the service.
- 19. The method of claim 15, wherein said part of the information comprises at least an indication of the protocol required for the service.
- 20. The method of claim 11, wherein the message relates to a certificate issuance service.
- 21. A mobile communication system comprising at least user equipment and a network comprising at least a network node, the system being configured to determine a network node address in on the basis of location information of user equipment, wherein the network node is in a location network of the user equipment.
- 22. The system of claim 21, wherein the location network is a visited network.
- 23. The system of claim 21 comprising a gateway network for certificate requests in a home network of the user equipment, the gateway network being configured to perform the network node address determination.
- 24. The method of claim 1, further comprising:
receiving in the mobile communication system a message from subscriber's user equipment, the message including subscriber's location information; checking whether or not the location information in the message corresponds to the location information maintained in the system; and if it does not correspond to the location information in the message, sending an error indication by using the maintained location information.
- 25. The method of claim 1, further comprising:
receiving in the mobile communication system a message from subscriber's user equipment, the message including subscriber's location information; checking whether or not the location information in the message corresponds to the location information maintained in the system; and using the location information in the message if it does not correspond to the maintained location information.
- 26. The method of claim 1, further comprising:
receiving in the mobile communication system a message from subscriber's user equipment, the message including subscriber's location information; checking whether or not the location information in the message corresponds to the location information maintained in the system; and if it does not correspond to the maintained location information, sending an error indication by using the location information in the message.
- 27. A method for transmitting to subscriber's user equipment information required for a service in a mobile communication system, the method comprising:
authenticating the subscriber; and transmitting to the user equipment at least part of the information using an authenticated channel.
- 28. A network node in a mobile communication system, wherein the network node (AU-H) is arranged to determine an address of another network node required for providing a service for a subscriber on the basis of subscriber's location information.
- 29. The network node of claim 28, wherein the network node (AU-H) is in a home network and the other network node is in a visited network.
- 30. User equipment in a mobile communication system, wherein the user equipment (UE) is arranged to receive at least part of the information required for a service in a location network of the user equipment after the user equipment has been authenticated.
- 31. The user equipment of claim 30, wherein the user equipment (UE) is arranged to receive said part of the information from a network node with which the user equipment was authenticated, the network node being in a home network.
