Abstract
Systems and methods are provided for authenticating Internet Protocol (IP) Multimedia Subsystem (IMS) applications in a User Equipment (UE). A method includes: receiving a first Session Initiation Protocol (SIP) REGISTER message from an IMS application operating on the UE; transmitting a response message to the IMS application based on the received first SIP REGISTER message; receiving a second SIP REGISTER message from the IMS application operating on the UE; determining authentication for the IMS application based on the received second SIP REGISTER message from the IMS application operating on the UE; and based on the step of determining authentication for the IMS application, if the IMS application is authorized, then transmitting information associated with the first and second SIP REGISTER messages toward a SIP node or if the IMS application is unauthorized, then discarding data associated with the first and second SIP REGISTER messages.
