Abstract

Embodiments for providing an architecture for WebRTC to access Internet Protocol (IP) multimedia subsystem (IMS) are generally described herein. In some embodiments, a non-IMS user equipment (UE) is provided along with an Application Signaling Interworking Function (ASIF) co-located with the non-IMS UE. The non-IMS UE is arranged to send a register message to the ASIF for registering the non-IMS UE with an IMS core. The ASIF is arranged to translate the register message from the non-IMS UE to IMS-based signaling and to register the non-IMS UE with the IMS core using the register message translated to IMS-based signaling.
