Abstract
The method includes following steps. Video signal terminals register on gatekeeper (GK). GK informs the central service management system about the uplink state information of nodes. The central service management system determines which MCU the meeting defined by the node is carried on, and informs MCU about online information of the node. MCU determines whether an invitation of becoming a member should be sent out to the node. The invention carries out automatic calling of the node uplink through GK, preventing MCU from periodic polling so as to save time and raises initiatory efficiency of the node. Automatic calling of uplink omits the dialing procedure of video signal terminals so as to simplify operation. Special service number makes terminals not need to memory meeting number. Video signal terminals through third party authentication and address parsing make management strategy more flexible.
Description
Technical field
The present invention relates to TV conference system, particularly, can make the node affiliation as early as possible in different ways of registration, gateway (GK) Enhancement Method in the videoconferencing operation of saving conference dispatching time.
Background technology
In existing TV conference system, conference dispatching generally adopts following three kinds of modes:
First kind: the nodal information that on MCU (multiple spot processing unit), defines affiliation, thereby adopt point-to-point mode that these nodes are called out into by MCU and form a meeting, again invite adding by MCU every a period of time for the node of not finishing calling at that time, its scheduling process as shown in Figure 1, concrete steps are as follows:
A:MCU will dispatch video terminal 1 and video terminal 2 joins a meeting, and MCU at first mails to GK with the another name of video terminal, to obtain the IP address of video terminal from GK;
B: make a call to two video terminals;
C: judge whether video terminal is registered on GK,,, will invite the video terminal affiliation just GK parses the IP address of video terminal if registered; If do not have registration, GK just can not parse the IP address of video terminal, again because GK and MCU are separate equipment, video terminal is only got in touch with GK, therefore MCU does not know when video terminal is registered on GK, and MCU must periodically send the address resolution request to GK for this reason, accepts request up to GK, parse the IP address, video terminal is invited affiliation.
Second kind: the meeting-place name of video terminal direct calling MCU, by MCU this node is put into correct meeting-place, its scheduling process as shown in Figure 2, concrete steps are as follows:
A: video terminal will add the meeting of MCU, at first meeting number is mail to GK to obtain the IP address of MCU;
B: make a call to MCU by the IP address that obtains, after the MCU call accepted, video terminal just joins in the meeting of MCU.
The third: the processing of calling transfer, process as shown in Figure 3, concrete steps are as follows:
A: as first ground the 2 standby each other of two video terminals 1 arranged, wherein have a video terminal on GK, to register, want to second now to have a meeting with first ground, at first send to second the name of video terminal 1 to GK by GK;
B:GK goes to judge whether video terminal 1 is registered, if registration is then called out and finished; If do not have registration, then GK can't to second return the address of video terminal 1, this calling can not be finished, and to second send the signal of call failure;
C: after receiving call-failure signal to second, send to the name of video terminal 2 again to GK, obtain the address of video terminal 2 after, just carry out meeting on first ground.
But may there be following shortcoming in above-mentioned three kinds of modes under several situations:
A: some node of possibility is not online when holding a meeting owing to MCU, thereby can exist scheduling unsuccessful, influences the shortcoming that meeting is held smoothly.
B: do not dispatch successful meeting-place for MCU,, and then influence the treatment effeciency of GK and MCU because MCU does not know when online node is, thereby must periodically send the address resolution request to GK.
C: since MCU when having a meeting at every turn meeting number do not resemble the telephone number fixing, so the user must send the IP address that meeting just can obtain MCU if want to GK when calling out MCU and join in the meeting, the each meeting of user all must be remembered meeting number like this, cumbersome, especially when meeting was number long, memory was complicated more.
D: when a certain local video terminal more for a long time, the calling party does not know which video terminal is available now, must be constantly initiates the address resolution request to GK and judges which video terminal can use, GK can not carry out calling transfer automatically.
Summary of the invention
The Enhancement Method that the purpose of this invention is to provide a kind of GK makes the node affiliation as early as possible in different ways of registration, the time of saving conference dispatching.
For achieving the above object, the GK Enhancement Method comprises step in the videoconferencing operation:
Video terminal is registered to GK (gateway);
The state information notification center business management system that GK reaches the standard grade node;
Which MCU is the center business management system judge the meeting of this node definition at, and with node online information notice MCU;
MCU judges whether that sending affiliation to this node invites.
Because the present invention has adopted above-mentioned technical scheme, so have following several advantage:
A: use GK to carry out node and reach the standard grade and call out automatically, avoided the periodic queries of MCU, saved the time, improved the affiliation efficient of node.
B: using reaches the standard grade calls out automatically, has avoided the dialing procedure of video terminal, has simplified the operation of video terminal.
C:GK makes video terminal need not remember the meeting number of MCU to the address resolution method of shortcode, has avoided the trouble in the memory, makes node add the meeting-place and becomes easily, thereby improved the efficient of whole meeting.
D: video terminal authenticates by GK request third party, alleviated the processing pressure of address resolution GK, special parsing authenticating device by the outside, both strengthened reliability, also improved the processing speed of node being resolved authentication, the disposal ability of GK is strengthened, node is increased by the chance of GK affiliation, improved efficient, and then made the management strategy of video terminal more flexible.

Embodiment
Method of reaching the standard grade calling automatically of the present invention has solved the problem of the not online necessary periodic scheduling of node when the MCU port operation meeting.As shown in Figure 4, when video terminal when GK registers, the state information notification center business management system that GK reaches the standard grade node, the center business management system judges the meeting of this node definition is at which MCU, and with node online information notice MCU, at this moment MCU judges whether the current node that has been defined in a certain meeting joins, if do not have, then make a call, invite this node affiliation to this node.
Shortcode of the present invention is called out the problem that has solved video terminal calling MCU meeting number difficult note.As shown in Figure 5, video terminal is wanted to join in the meeting, if it does not know this meeting is on which MCU, it can use a special service number (being similar to 168) to send the address resolution request to GK so, GK sees that the number of calling is that shortcode then is sent to it center business management system, the center business management system judges meeting that this video terminal will add is on which MCU, and the IP address of this MCU returned to video terminal by GK, thereby make video terminal can call out MCU.
The present invention uses the selection problem of service number solution calling transfer video terminal.As shown in Figure 6, as a certain place two video terminals are arranged, as long as a video terminal job is arranged during meeting, at this moment these two video terminals can be put into a group, externally only use a number (being similar to the chairman's number among the phone agent), node only uses this number to make a call to GK, GK judge the number of this calling be the service number, then judge the node resource operating position that this service is provided, as presence, whether available etc., then strategy according to priority find out a resource can with the video terminal address return to node, thereby finish calling, as long as a video terminal possibility is arranged in this case, just can once finish calling.
Carrying out the third party by GK authenticates.As shown in Figure 7, when video terminal was registered to GK, GK mail to certificate server with nodal information by radius protocol, and certificate server judges according to certain strategy whether this register node is legal, and authentication result returned to GK, GK determines whether allowing the node registration according to authentication result.
Carry out third party's address resolution by GK.As shown in Figure 8, when video terminal will be called out, at first send the address resolution request to GK, GK carries out the address resolution request by ldap protocol to third party's address server, ldap server finds called address according to called another name, and the address returned to node by GK, thereby finish whole calling procedure.
