Abstract: The present invention concern methods and apparatuses for handling public identities in an Internet Protocol Multimedia Subsystem, IMS, network. A CSCF node receives information indicating a set of distinct public identities, within a range of a wildcarded public identity, which set of distinct public identities are not in the same Implicit Registration Set (IRS) as the wildcarded public identity. The information is received from a Home Subscriber Server (HSS) node. The CSCF node stores the information indicating the set of distinct public identities, which are not in the same IRS, in the CSCF node for allowing matching of an originating request to the information indicating the set of distinct public identities, which are not in the same IRS.

Abstract: A method of securing a mobile wireless telecommunication device to restrict access to data stored in the device. The method including registering the device with a network-based server associated with a given user. In the event that the user wishes to restrict access to data stored on the device when the user does not have access to the device, but has access to an alternative communication device, the user is authenticated, via said alternative communication device, to an IP Multimedia Subsystem (IMS) network and, on the basis of such authentication, the user is allowed to access the server and send to the server an instruction to lock the mobile wireless telecommunication device.

Abstract: The present invention concern methods and apparatuses for handling public identities in an Internet Protocol Multimedia Subsystem, IMS, network. A Serving Call Session Control Function, S-CSCF, node receives a message including a public identity. If the message does include a profile key with a wildcarded identity, the S-CSCF uses the wildcarded identity received with the profile key to fetch a user/service profile related to the wildcarded identity. If the message does not include a profile key with a wildcarded identity, the S-CSCF 125 uses the public identity received in the message to fetch a user/service profile related to the public identity.
