Real time communication method, terminal device, real time communication server and real time communication system

A method, comprising:

• sending, by a real time communication (RTC) server to a first terminal, call request information that a second terminal sent to the RTC server for a call request to the first terminal, wherein the call request is for the first terminal to initiate a WEB-based RTC session with the second terminal through a WEB-based RTC application, wherein the call request information is received by the first terminal outside the WEB-based RTC application, and wherein the call request information carries a second identifier of the WEB-based RTC application unique to the second terminal;
• receiving, by the RTC server, request information sent by the first terminal indicating that the first terminal accepts the call request based on the second identifier;
• and
• returning, by the RTC server, information of the WEB-based RTC application to the first terminal after receiving the request information sent by the first terminal;
• wherein the first terminal, based on the information of the WEB-based RTC application returned by the RTC server, opens the WEB-based RTC application and establishes the WEB-based RTC session with the second terminal through the WEB-based RTC application.

A terminal device, comprising:

• a transceiver configured to receive, from a real time communication (RTC) server, call request information of another terminal making a call request to the terminal device, wherein the call request is for the terminal device to initiate a WEB-based RTC session with the other terminal through a WEB-based RTC application, wherein the call request information is received by the transceiver from the RTC server outside the WEB-based RTC application, and wherein the call request information carries a second identifier of a WEB-based RTC application unique to the other terminal;
• and
• a processor configured to:
• determine, according to the second identifier, whether to accept the call request;
• and
• initiate, when accepting the call request, the WEB-based RTC session with the terminal device through the WEB-based RTC application, by being configured with the transceiver to:
• send request information to the RTC server for opening the WEB-based RTC application with the terminal device;
• receive information of the WEB-based RTC application from the RTC server in response to the request information sent to the RTC server for opening the WEB-based RTC application in the terminal device;
• and
• establish the WEB-based RTC session with the other terminal through the WEB-based RTC application.

A server, comprising:

• a transceiver configured to:
• receive call request information from a second terminal making a call request to a first terminal, wherein the call request is for the first terminal to initiate a WEB-based real time communication (RTC) session with the second terminal through a WEB-based RTC application;
• send the call request information to the first terminal, to be received by the first terminal outside the WEB-based RTC application, wherein the call request information carries a second identifier of a WEB-based RTC application unique to the second terminal;
• receive request information sent by the first terminal indicating that the first terminal accepts the call request based on the second identifier;
• and
• return information of the WEB-based RTC application to the first terminal, so that after receiving the request information from the first terminal;
• wherein the first terminal, based on the information of the WEB-based RTC application returned by the server, opens the WEB-based RTC application and establishes the WEB-based RTC session with the second terminal through the WEB-based RTC application.
