  • Patent number: 9712593
    Abstract: In accordance with an embodiment, described herein is a system and method for real-time communication signaling between HTML5 endpoints and between HTML5 endpoints and the IMS Core of a telecommunication network. In an embodiment the system includes a WebRTC Session Controller (WSC) communicating over an Internet domain protocol with a client-side controller. The WSC terminates web communications with the client-side, parses, and normalizes the Web communications into an internal protocol suitable for communication with telecommunications network systems. The client-side controller provides a JavaScript API that encapsulates the signaling aspect of a communication session of the HTML5 application, including gathering media description, establishing signaling channels, and exchanging media descriptions with the WSC, populating the relevant WebRTC objects, managing the call after it has been established.
