Real-time communication signaling gateway

A method for real-time communication signaling between a client-side application operating on user equipment and a telecommunications network, the method comprising:

• providing in the telecommunications network a telecommunications network gateway comprising a server-side web signaling engine and a service composition controller, the network gateway a node on the telecommunications network;
• providing a WebSocket interface to a real-time communication controller of said server-side web signaling engine;
• receiving JavaScript Object Notation (JSON) communications comprising requests for services from said client-side application via said WebSocket interface;
• using an implicit sequence numbering protocol in which the real-time communication controller sends acknowledgement messages in response to said JSON communications indicating that said JSON messages have reached the real-time communication controller wherein each said acknowledgement message is indicative that a particular JSON message having a particular sequence number and all JSON messages having a sequence number lower than the particular sequence number, have been received by said real-time communication controller;
• terminating the JSON communications with the real-time communication controller;
• activating the client-side application by sending a push notification from the server-side web signaling engine to the user-equipment to resume communication over said WebSocket interface where said client-side application has entered a standby state in response to a period in which no traffic was communicated over said WebSocket interface;
• parsing session description protocol (SDP) information from the JSON communications;
• mapping the parsed SDP information to the Session Initiation Protocol (SIP) protocol, thereby creating SIP communications from the received JSON communications;
• transmitting the SIP communications from the real-time communication controller in a binary SIP protocol to the service composition controller of the telecommunications network gateway responsive to said JSON communications;
• communicating requests for services from said service composition controller to internal services offered via the telecommunications network in response to said SIP communications transmitted from the real-time communication controller in the binary SIP protocol;
• and
• providing services, responsive to said requests for services, from the internal services of the telecommunications network, to said client-side application, via said WebSocket interface of said real-time communication controller of said server-side web-signaling engine, in response to said SIP communications transmitted from the real-time communication controller.

A non-transitory computer readable storage medium including instructions stored thereon for supporting real-time communication signaling between a client-side application operating on user equipment and a telecommunications network, which instructions, when executed by a computer system, cause the computer system to perform steps comprising:

• providing in the telecommunications network a telecommunications network gateway comprising a server-side web signaling engine and a service composition controller, the network gateway a node on the telecommunications network;
• providing a WebSocket interface to a real-time communication controller of said server-side web signaling engine;
• receiving JavaScript Object Notation (JSON) communications comprising requests for services from said client-side application via said WebSocket interface;
• using an implicit sequence numbering protocol for said JSON communications in which the real-time communication controller sends acknowledgement messages in response to said JSON communications indicating that said JSON communications have reached the real-time communication controller wherein each said acknowledgement communication is indicative that a particular JSON communication having a particular sequence number and all JSON communications having a sequence number lower than the particular sequence number, have been received by said real-time communication controller;
• terminating the JSON communications with the real-time communication controller;
• parsing session description protocol (SDP) information from the JSON communications;
• mapping the parsed SDP information to the Session Initiation Protocol (SIP) protocol, thereby creating SIP communications from the received JSON communications;
• transmitting the SIP communications from the real-time communication controller in a binary SIP protocol to the service composition controller of the telecommunications network gateway responsive to said JSON communications;
• communicating requests for services from said service composition controller to internal services offered via the telecommunications network in response to said SIP communications transmitted from the real-time communication controller in the binary SIP protocol;
• and
• providing services, responsive to said requests for services, from the internal services of the telecommunications network, to said client-side application, via said WebSocket interface of said real-time communication controller of said server-side web-signaling engine, in response to said SIP communications transmitted from the real-time communication controller.
