METHOD, DEVICE, AND SYSTEM FOR IMPLEMENTING ELECTRONIC WHITEBOARD IN AUDIO/VIDEO CONFERENCE
First Claim
1. A method for implementing an electronic whiteboard in an audio/video conference, comprising:
- creating, by a server, an electronic whiteboard, and sending, by the server, a first extended message to a first user equipment (UE) and a second UE in a Session Initiation Protocol (SIP) audio/video conference, so as to instruct the first UE and the second UE to initialize the electronic whiteboard;
receiving, by the server, a second extended message sent by the first UE, wherein the second extended message contains an operation instruction of the electronic whiteboard; and
sending, by the server, the second extended message to the second UE.

Abstract
A method, a device, and a system for implementing an electronic whiteboard in an audio/video conference are provided. The method includes the following steps. An electronic whiteboard is created. A first extended message is sent to a first user equipment (UE) and a second UE in a Session Initiation Protocol (SIP) audio/video conference, so as to instruct the first UE and the second UE to initialize the electronic whiteboard. A second extended message containing an operation instruction of the electronic whiteboard sent by the first UE is received. The second extended SIP INFO message is sent to the second UE. Thus, a function of the electronic whiteboard is integrated in an SIP audio/video conference.
