Abstract
In some aspects, a Session Initiation Protocol (SIP) proxy server of an Internet Protocol Multimedia Subsystem (IMS) infrastructure is configured to process SIP registration requests. In operation, the SIP proxy server receives a single SIP registration request that includes a plurality of IMS Public User Identities (IMPUs). The SIP proxy server then authenticates the plurality of IMPUs to determine which of the plurality of IMPUs are authorized IMPUs. A plurality of SIP registrations are then performed by the SIP proxy server, wherein each SIP registration of the plurality of SIP registrations is a SIP registration of a respective authorized IMPU.
