System and method for transmitting rich media information in call process, and device

A method for transmitting rich media information in a call process, comprising:

• establishing, by a second terminal, a call connection to a first terminal by using a real-time transport protocol (RTP) data link;
• parsing, by the second terminal, a real-time transport control protocol (RTCP) packet based on receiving the RTCP packet from the first terminal, to obtain a code in the RTCP packet;
• and
• searching, by the second terminal, a second rich media library corresponding to the second terminal for rich media information corresponding to the code, and responding to the rich media information, wherein same rich media information corresponds to a same code in a first rich media library corresponding to the first terminal and the second rich media library corresponding to the second terminal.

A first terminal, comprising:

• at least one processor;
• and
• a memory, wherein the memory stores computer-executable instructions, and wherein the at least one processor executes the computer-executable instructions stored in the memory to cause the first terminal to perform:
• establishing a call connection to a second terminal by using a real-time transport protocol (RTP) data link;
• determining, based on a user operation, target rich media information selected by a user in the first terminal;
• searching a first rich media library for a code corresponding to the target rich media information, wherein the first rich media library corresponds to the first terminal;
• encapsulating the code found in the first rich media library corresponding to the target rich media information into a real-time transport control protocol (RTCP) packet;
• and
• sending the RTCP packet obtained after encapsulating to the second terminal, wherein same rich media information corresponds to a same code in the first rich media library corresponding to the first terminal and a second rich media library corresponding to the second terminal.
