Patent abstract
An authentication and validation architecture utilizing a P-CSCF (proxy-call session control function) service to validate a source IP address against a registered contact IP address upon receiving an initial request for a dialog or a standalone request (except REGISTER) from a registered user. This provides a security measure to prevent IMS (IP multiemdia subsytem) identity spoofing, when SIP security (IPsec) access security is not enabled, or not used, between the user equipment (UE) and P-CSCF service.
