초록 ▼

A technique for protecting location information of a subscriber in a mobile network is disclosed. A User Mobility Server (UMS) receives a first query from a first call state control function (CSCF). The UMS transmits a call setup and a subscriber identity to a servicing-call state control function (S-CSCF). The S-CSCF may have no record of the subscriber identity due to a restart are some other event. The UMS receives a second query from the S-CSCF based in part of the subscriber identity. The UMS transmits a home address of a mobile station to the S-CSCF. The UMS may also transmit a profile download to the S-CSCF.

1. A method comprising: receiving, from a first server at a second server, a transport address and an address of the first server;receiving, at the second server, a request from the first server to restore the transport address; andin response to the request from the first server to restore the transport address, communicating the transport address to the first server from the second server. 2. The method of claim 1, wherein the second server is a home subscription server (HSS). 3. The method of claim 1, wherein the first server is a serving-call state control function (S-CSCF). 4. The method of claim 1, further comprising storing the transport address at the second server. 5. The method of claim 4, wherein the storing the transport address comprises storing the transport address in a non-volatile memory of the second server. 6. The method of claim 1, wherein the transport address comprises a care-of-address of a mobile subscriber. 7. The method of claim 1, wherein the receiving, at the second server, the request from the first server to restore the transport address is in response to a loss of the transport address by the first server. 8. The method of claim 1, wherein the receiving the transport address and an address of the first server comprises receiving an application level update message at the second server from the first server. 9. An apparatus comprising: a receiver configured to receive a transport address and an address of a first server from the first server, wherein the receiver is further configured to receive a request to restore the transport address from the first server; anda transmitter configured to communicate the transport address to the first server in response to the request to restore the transport address from the first server. 10. The apparatus of claim 9, wherein the apparatus is an HSS. 11. The apparatus of claim 9, wherein the first server is an S-CSCF. 12. The apparatus of claim 9, further comprising a non-volatile memory configured to store the transport address at the second server. 13. The apparatus of claim 9, wherein the transport address comprises a care-of-address of a mobile subscriber. 14. The apparatus of claim 9, wherein the receiver is further configured to receive the request from the first server to restore the transport address in response to a loss of the transport address by the first server. 15. The apparatus of claim 9, wherein the receiver is further configured to receive the transport address and an address of the first server in an application level update message from the first server. 16. A non-transitory computer-readable medium having instructions stored thereon that, upon execution by a computing device, cause the computing device to perform operations comprising: receiving, from a first server, a transport address and an address of the first server;receiving a request from the first server to restore the transport address; andin response to the request from the first server to restore the transport address, communicating the transport address to the first server. 17. The non-transitory computer-readable medium of claim 16, wherein the computing device is an HSS. 18. The non-transitory computer-readable medium of claim 16, wherein the first server is an S-CSCF. 19. The non-transitory computer-readable medium of claim 16, wherein the operations further comprise storing the transport address in a non-volatile memory. 20. The non-transitory computer-readable medium of claim 16, wherein the transport address comprises a care-of-address of a mobile subscriber.
