    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.

    Abstract translation: 提供了用于在用户设备(UE)中验证因特网协议(IP)多媒体子系统(IMS)应用的系统和方法。 一种方法包括:从在UE上操作的IMS应用接收第一会话发起协议(SIP)REGISTER消息; 基于所接收的第一SIP REGISTER消息向IMS应用发送响应消息; 从在UE上操作的IMS应用接收第二SIP REGISTER消息; 基于从UE上运行的IMS应用接收的第二SIP REGISTER消息确定IMS应用的认证; 并且基于为IMS应用确定认证的步骤,如果IMS应用被授权,则向SIP节点发送与第一和第二SIP注册消息相关联的信息,或者如果IMS应用未授权,则丢弃与 第一和第二SIP注册消息。
