摘要:
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.
