Abstract:
A group communication method, device, and system, the method comprising: a control entity receives a second message bearing a second group ID sent by a first mobile device, the second group ID being from a first message sent by a second mobile device, and the second message being used for requesting to join a second group identified by the second group ID; the control entity sends a third message to the first mobile device, the third message bearing a group address corresponding to the second group; the address corresponding to the second group is used for sending messages in the second group after the first mobile device is added to the second group.
