Abstract: 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.

Abstract: A technique for protecting location information of a subscriber in a mobile network is disclosed which forwards a registration request from the subscriber to an S-CSCF including the subscriber's TA and then forwarding a location update from the S-CSCF to an HSS including the subscriber's TA. Upon the S-CSCF losing data, lost data may be restored to the S-CSCF from the data stored in the HSS. The HSS may store data in a non-volatile memory such as a hard disk drive. The technique may also include forwarding a registration request from the subscriber to an S-CSCF including the subscriber's TA and then forwarding a location update from the S-CSCF to an HSS and storing data in a non-volatile memory such as a hard disk drive in the S-CSCF so as to be protected against loss. Upon the S-CSCF losing data, lost data including the subscriber's TA may be restored to the S-CSCF from the data stored in the S-CSCF.

Abstract: According to an embodiment of the present invention, a system is provided that includes a cellular network, a Public Switched Telephone Network (PSTN) and a mobile IP-telephony network (MIPTN). Both the cellular network and the MIPTN include a Home Function and one or more visited Functions. MIPTN subscribers can roam within the MIPTN. Also, a Gateway Function interfaces the PSTN and the MIPTN to allow roaming between the cellular network and the MIPTN. The Gateway Function performs a dynamic mapping function between PSTN/cellular addresses (e.g., in E.164 format) and MIPTN addresses (e.g., IP addresses) to allow registration and call delivery for subscribers roaming between the cellular network and the MIPTN. A similar type of Gateway Function also allows Short Message Service (SMS) messages to be delivered over the MIPTN as well.
