摘要:
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.
