Technical scheme of the present invention is: will not support the IP address of the endpoint device of GK to dispose to the MCU that holds a meeting as call information;
When MCU made a call to the endpoint device of not supporting the gatekeeper, MCU searched the IP address that whether disposes this endpoint device in conference convening information, if having, directly used this IP address and this endpoint device to set up to call out and was connected; If do not have, stop this calling procedure;
When the endpoint device of not supporting GK when MCU calls out, MCU judges whether active conference allows this endpoint device to participate in, if, then accept the call request of this endpoint device, this endpoint device is added meeting, if not, refuse the call request of this endpoint device.
In technique scheme, can when MCU when the endpoint device of not supporting the gatekeeper makes a call, earlier send ARQ (AdmissionRequest to GK, call out the request of access), after receiving that GK replys ARJ (AdmissionReject calls out admission reject), MCU searches the IP address that whether disposes this endpoint device in conference convening information, if have, directly use this IP address and this endpoint device to set up to call out and be connected; If do not have, stop this calling procedure.
In technique scheme, can work as do not support GK endpoint device when MCU calls out, earlier send ARQ to GK, after receiving that GK replys ARJ, MCU judges whether active conference allows this endpoint device to participate in, if, then accept the call request of this endpoint device, this endpoint device is added meeting; If not, refuse the call request of this endpoint device.
Employing the method for the invention has solved the endpoint device of not supporting GK and also can participate in the meeting of supporting GK, and is convenient for users to use, saved user's spending.

Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described further.The present invention is suitable for based on the TV conference system of agreement H.323 for all.
To not supporting the endpoint device of GK, MCU has a detailed description in the summary of the invention part to the method that it makes a call or it makes a call to MCU.
Generally speaking, the endpoint device of supporting GK is arranged simultaneously and do not support the endpoint device of GK to participate in a conference together, in this case, should will not support the IP address of the endpoint device of GK to dispose to the MCU that holds a meeting earlier as call information.When MCU calls out, all earlier carry out the call address request for all endpoint devices to GK, return the endpoint device of call address for GK, promptly support the endpoint device of GK directly to call out, do not return the endpoint device of call address for GK, promptly do not support the endpoint device of GK directly to use the IP address in the configuration information to call out.Certainly, also can be: when MCU calls out, see if there is the IP address for first from configuration information, the searching of all endpoint devices, if have, then directly directly call out with the IP address in the configuration information, if do not carry out the call address request to GK again, GK returned the endpoint device of call address and call out.
When MCU receives the call request of endpoint device, send ARQ to GK: if GK replys ACF (AdmissionConfirm, call out admission confirm), show this endpoint device support GK, MCU judges whether to allow this endpoint device to add meeting according to conference convening information, if allow, then accept the call request of this endpoint device, and this endpoint device is added meeting; If do not allow, then refusal is called out.If GK replys ARJ, show that this endpoint device do not support GK, MCU judges whether to allow this endpoint device to add meeting according to conference convening information, if allow, then accepts the call request of this endpoint device, and this endpoint device is added meeting; If do not allow, then refusal is called out.
What Fig. 1 described is the equipment composition diagram of the multipoint conference among the present invention.The equipment of multipoint conference has GK respectively among the figure, MCU, and a plurality of endpoint devices, MCU wherein, endpoint device 1, endpoint device 2, endpoint device 3 is all supported GK, all registers to GK, endpoint device A does not support GK, registers to GK.Be endpoint device 1, endpoint device 2, endpoint device 3 and endpoint device A participate in the meeting C that holds together on MCU.
What Fig. 3 described is that MCU is as caller in the prior art, and the endpoint device of supporting GK is as called call signalling flow figure.MCU at first sends ARQ to GK, and called GK can find the log-on message of this endpoint device in order to support the endpoint device of GK, therefore sends ACF to MCU.After MCU receives the ACF of GK response, take out the IP address of called end point equipment from ACF message, and send Setup message to the endpoint device of this IP address, beginning is set up with it and is called out connection, invites the other side's affiliation.
Fig. 5 is that MCU is as caller among the present invention, and the endpoint device of not supporting GK is as called call signalling flow figure.MCU at first sends ARQ to GK, because called for not supporting the endpoint device of GK, GK can't find called log-on message, so can reply ARJ message to MCU.After MCU receives the ARJ that GK responds, search the IP address information of this endpoint device in the information of pre-configured participant endpoint device, and send Setup message to the endpoint device of this IP address, beginning is set up with it to call out and is connected, and invites the other side's affiliation.
What Fig. 7 described is that MCU supports the call signalling flow figure of the endpoint device of GK as caller as called in the prior art.After MCU receives the Setup message of call request, send ARQ to GK, because this endpoint device is supported GK, then GK returns ACF message to MCU, after MCU receives ACF message, judge whether this endpoint device is the participant endpoint device of active conference, if call accepted is sent Connect message to this endpoint device, set up with it and call out connection, allow the other side to add meeting.
What Fig. 9 described is that MCU does not support the call signalling flow figure of the endpoint device of GK as caller as called among the present invention.After MCU receives the Setup message of call request, send ARQ to GK, because this endpoint device is not supported GK, so GK returns ARJ message to MCU, after MCU receives ARJ message, judge whether this endpoint device is the participant endpoint device of active conference, if the call accepted request is sent Connect message to this endpoint device, set up with it and call out connection, allow the other side to add meeting.
