In this embodiment of the present invention, the signaling service module 101 sends a call request CallClient for sending a third party call to the central gateway service unit 1041 when detecting that the participant terminal is a third party terminal and the private protocol terminal status dstatus of the participant terminal is not 2. And receives the messages, such as registration, conference entry, conference information acquisition, layout information acquisition, audio/video stream request and the like, which are sent by the central gateway service unit 1041 and used for showing the simulated terminal account of the third party terminal, and saves the terminal state dstatus of the private protocol.
Specifically, when the video conference system is started, the signaling service module 101 loads a terminal device list including participant terminals, where the terminal device list includes analog terminal accounts corresponding to the participant terminals, and the participant terminals include third-party terminals. Before the signaling service module 101 sends the third party call request or before feedback information for successful call of the third party terminal is received, the signaling service module 101 may set the call result status of the participant terminal to 0, call failure, and set the private protocol terminal status dstatus to 0, unregistered. Wherein the call result status may include 0 call failure or 1 call success, and the private-protocol terminal status may include 0 unregistered, 1 not joined, or 2 joined.

c) And the third party terminal is actively hung up or passively hung up, dstatus is set to be 1 and registered, and the call result of the third party terminal, namely, the status is set to be 0 and the call is failed.
d) And when the third party terminal logs out, setting dstatus of the account number of the simulation terminal configured with the third party terminal in the central gateway service unit as 0 to be unregistered.
e) If the dstatus of any participant terminal changes, the terminal issuing state of the participant terminal is negative.
In this embodiment of the present invention, the gateway service module 101 is further configured to receive an intra-session signaling reportcall result sent by the central gateway service unit 1041 using the simulated terminal account of the third party terminal, so as to obtain and store a call result cstatus of the third party terminal. The value of call result status may be 0 call failure or 1 call success.
It should be noted that, for the initiator of the current conference, the signaling service module 101 is further configured to obtain a conference number of the participant terminal currently entering the conference, and set the conference state issue flag to be no.
In addition, the gateway service module 101 also periodically detects a conference state issue flag, and if the conference state issue flag is negative, the gateway service module 101 may calculate, for the third-party terminal, a terminal issue state of the third-party terminal by using a product calculation method of dstatus and cstatus:
pstatus = dstatus * cstatus
wherein the pstatus represents a terminal release state of the third-party terminal;
dtatus represents that the central gateway service unit utilizes the simulation terminal account number of the third party terminal and the private terminal protocol terminal state of the signaling service module based on the private protocol;
cstatus represents the call result of the third party terminal.
For the private terminal, the private terminal of the private terminal may issue the status dstatus as the terminal issuing status pstatus.
Further, the gateway service module 101 may also send status messages of the conferee terminals in the terminal device list to the conference control service and the conferee terminals, where the status messages may include terminal release status pstatus of all the conferee terminals.
In this embodiment of the present invention, the central gateway service unit 1041 is further configured to receive a third party call request from the signaling service module 101, and perform authentication registration of the third party terminal to the signaling service through a private protocol according to the third party call request.

Correspondingly, the third-party gateway service unit is also used for receiving the gateway task adding request, calling an IP port according to the third-party terminal carried by the gateway task adding request, and completing calling the third-party terminal through a third-party protocol.
Specifically, after the central gateway service unit 1041 receives the third party call request CallClient sent by the signaling service module 101, the central gateway service unit 1041 applies for authentication registration of the third party terminal to the signaling service module through the simulated terminal account and the password of the third party terminal 1042 based on the private protocol. Furthermore, the central gateway service unit 1041 initiates a request for acquiring conference information to the signaling service module 10 by using the analog terminal account of the third party terminal, and acquires the media IP and the port, i.e., rip and rport, of the media service.

And the central gateway service unit 1041 may initiate a request for adding a gateway task to a transport protocol supported by a third party terminal, such as an H323 gateway service, a standard SIP gateway service, and the like, based on the third party protocol. The add gateway task request may carry the following parameters: gateway service media IP port, media service IP and port, and third party terminal call IP and port, i.e., lip, iport, rip, rport, cip, and cport. The third-party gateway service unit 1042 may initiate third-party active call signaling to the third-party terminal using cip (third-party terminal call IP) and port cport in the add gateway task request.
In this embodiment of the present invention, the central gateway service unit 1041 is further configured to: receiving heartbeat information sent by the third-party gateway service unit 1042, wherein the heartbeat information includes a terminal list of a third-party terminal actively hanging up conference connection; and initiating a conference hanging-up request to the signaling service aiming at the third-party terminal actively hanging up the conference connection according to the terminal list so as to complete the hanging-up of the conference connection performed by the central gateway service unit through simulating the third-party terminal by a private protocol.
