Background technology
The network of scheduling industry is the network of a special communication, it and traditional communication network are very different, it not only possesses all functions of all public network communications, have more the function that many plain old telephone networks do not possess, for example: dispatcher's phone is with the line is busy, the higher-level user can the intrusion lower-level user, mean, even if two users converse, if the higher-level user dials this wherein phone, system can cut off original conversation automatically, ensures that high level user at first converses.Because traditional dispatching patcher is to transform to form on original PSTN network, can only satisfy common call function, in recent years, constantly full-fledged along with the ip network, increasing video dispatching appears in the scheduling industry, the function of the conversation that not only can satisfy more possesses the condition that transmits both sides' video, makes communication convenient fast.
Present video dispatching system generally all adopts following implementation method: calling called (calling and called all possess video and audio-frequency function), caller is at first to gk (Gatekeeper gatekeeper, a dispatch server) application mcu (Media Control Unit multipoint control unit, media server) resource, unsuccessful then this call failure of application; Apply for successfully, then caller is called out called by dispatch server gk, after called off-hook is answered, send video and voice data to mcu, the video and the audio frequency of caller simultaneously also send to media server mcu, are responsible for transmitting both sides' video and audio frequency by media server mcu, both sides begin normal communication, if called refusal is answered or long-time ring unanswered, then discharge media server mcu resource, call failure.
But in the application of reality, high level user wishes can see called video before called active is answered, thereby can explain and understand called state.Such as: leader (higher-level user) can wish to understand at any time the working condition of person on duty's (called).
Summary of the invention:
The present invention is in order to solve deficiency of the prior art, the implementation method of video dispatching in particularly a kind of dispatching communication.
Technical scheme of the present invention is as follows:
The implementation method of video dispatching in a kind of dispatching communication, this method comprises the steps:
Step 1, calling party initiate video call, to dispatch server GK application idle medium server MCU, GK searches idle MCU, send message simultaneously to MCU, notice MCU initialization, MCU replys GK initialization success, and GK replys the calling party and applies for MCU success, the basic parameter of informing calling party MCU simultaneously.When the calling party makes a call, can automatically own user class own be sent to the GK server, the rank of callee's record itself after receiving the call information of server forwards, is judged calling party and callee's rank.
When the callee judged calling party and callee's rank, the calling party was superior to called rank, and then the callee directly sends video to MCU, and MCU is transmitted to the calling party to video; Otherwise, have only after the callee selects to answer calling party and the called forwarding that can pass through MCU just now, the audio frequency and video instant messaging of carrying out.
Step 2, calling party apply for adding MCU, and GK replys and adds the MCU success;
Step 3, calling party begin to call out the callee, and the server forwards message related to calls is given the callee, when the callee receives message related to calls, send video to MCU, when MCU receives called video, transmit video immediately and give the calling party;
In the described step 1, the GK server can increase the rank that a field record keeps caller, is transmitted to called simultaneously.
By method of the present invention, when high level user wishes can see called video before called active is answered, thereby understand called operating state, can satisfy these high level users' specific demand.

Embodiment
Below in conjunction with the drawings and the specific embodiments, the present invention done describing in further detail.
With reference to Fig. 1, Fig. 2, the relation of GK server and MCU is the relation of one-to-many, MCU at first seeks the GK server in this territory when starting, MCU is subjected to the management of GK server, the GK server is responsible for the distribution of MCU resource, that is to say, when calling out generation, the GK server is responsible for seeking idle MCU, distributes to this call treatment video and voice resource.
The relation of GK server and CLIENT is the relation of one-to-many, and CLIENT at first seeks the GK server in this territory when starting, and the GK server is keeping the information of all CLIENT, comprising call information, and call state etc.All call signalings of CLIENT all pass through the GK server forwards.
With reference to Fig. 4, Fig. 5, CLIENT1 is caller among the figure, and CLIENT2 is called.The caller message that makes a call at first, the GK server sends message related to calls to called, and is called if caller is superior to, and comprises the information of forcing called transmission video in the message, otherwise waits for called answering.
Concrete calling procedure carries out according to the following step:
1. caller is to GK server application MCU resource;
2.GK the MCU resource of whois lookup free time, notice MCU initialization;
3.MCU the GK server is replied in the initialization success;
4.GK server is replied caller MCU resource bid success, and concrete the IP address and the port of informing calling party MCU;
5. caller sends message to GK server application adding MCU;
6.GK replying caller, server adds the MCU success;
7. caller sends message related to calls to the GK server, begins to call out called;
8.GK it is called that server is sought, and send message related to calls to called (if being superior to of caller is called, notifying called transmission video in the message)
9. called transmission video is to MCU;
Give caller 10.MCU transmit called video;
11. message is replied to the GK server in the called back of answering;
12.GK server is replied message and is given caller, informs calledly to answer;
13. called transmission audio frequency is to MCU;
Give caller 14.MCU transmit called audio frequency and video
15. caller sends audio frequency and video to MCU;
16.MCU transmitting the audio frequency and video of caller gives called.
