Technical field
The present invention relates to communication technical field, relate in particular to the implementation method of forced interposing and forced releasing in a kind of IP of being applicable to dispatching patcher.
Background technology
Forced interposing and forced releasing mechanism in the IP dispatching patcher has defined calls out authority for the restriction relation between different objects.When the visible dispatching terminal A with a certain calling authority attempts and has another visible dispatching terminal B that calls out authority when conversing; Called B possibly just converse certain calling under the control of authority with visible dispatching terminal C; This just relates to scheduling problem: if the calling privilege limit for height of called B in caller A, then caller can not interrupt or insert incoming call; If called calling authority is lower than caller, then caller just need be differentiated the calling authority with the visible dispatching terminal C of incoming call, if the calling authority of terminal C is higher than caller equally, then caller can not interrupt or insert incoming call; Only when calling authority called and conversation object C all was lower than caller, caller just was allowed to insert incoming call.
The method of current realization forced interposing and forced releasing is many based on number priority.It shows as through configuring telephone number priority on call server; IAD with forced interposing and forced releasing function obtains number priority; And pass through the user's of judgement request call number priority, urgency traffic can preferentially be inserted in the existing voice system.
The forced interposing and forced releasing function of this method depends on the IAD with forced interposing and forced releasing function, and need be on call server configuration number priority voluntarily.But in the IP dispatching patcher; IAD can't satisfy the visible dispatching terminal to scheduling requirement; And can increase server stress by the priority of server configures number, the most important thing is can not solve the requirement of dispatching under the urgent emergency situations only according to number priority.This kind problem particularly shows:
1., then possibly cause the untimely problem of issuing an order if be urgent call by intrusion, the conversation of tolling breakdown;
2. when the conversation of high priority is being carried out, the emergency of burst can't in time be passed on.
3. when meeting during by intrusion, owing to there not being meeting control authority metastasis to cause the meeting control authority to shift, the uncontrollable meeting of intrusion person.
4. when the meeting effector was dismantled, owing to there not being meeting control authority metastasis to cause the unmanned hosting of meeting, functions such as video broadcasting can't be used.
Summary of the invention

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment is elaborated.Should be emphasized that following explanation only is exemplary, rather than in order to limit scope of the present invention and application thereof.
The invention provides the implementation method of forced interposing and forced releasing in a kind of IP of being applicable to dispatching patcher; Pass through in calling the judgement of visible dispatching terminal call authority and Service Control Unit the conversion of meeting control authority is regulated and control to realize the intrusion in the IP scheduling and to toll breakdown the multipoint control unit Media Stream.
Initial condition:
As shown in Figure 1; Behind each unit starting of system; According to configuration; Service Control Unit (SCU) is set up message channel TCP with each visible dispatching terminal and multipoint control unit (MCU) and is connected, and Service Control Unit was a server end during this connected, and is responsible for monitoring each visible dispatching terminal and is connected with multipoint control unit; After connecting foundation, Service Control Unit and visible dispatching terminal can be accomplished the state dynamic real-time supervision of passage through " heartbeat ".Service Control Unit is allocated as a kind of resource storage visible dispatching terminal and multipoint control unit for business, as shown in Figure 2.
This setting of local number is accomplished through configuration in each visible dispatching terminal, have the number of visible dispatching terminal B2 like visible dispatching terminal C0, and visible dispatching terminal B2 and A1 also has the other side's telephone number.
The rank of supposing the visible dispatching terminal has 0-4, and 0 rank is the highest, and then on behalf of visible dispatching terminal C, C0 have the highest scheduling rank, and similarly, the scheduling rank of visible dispatching terminal A is lower than terminal C and is higher than terminal B; In addition, be 0-2 according to the urgency level of calling out with the urgent call grade setting.The rank and the urgent call rank at visible dispatching terminal depended in the judgement of class of call.
The break-in service flow process:
Behind B2 and A1 call setup, Service Control Unit has promptly write down the call information of this time calling, comprises the number of multipoint control unit and conversation.At this moment, C0 attempts to call out B2, and step is following:
C0 is with the number informing business control unit of the visible dispatching terminal B2 of this request conversation and to Service Control Unit application multipoint control unit resource;
Whether Service Control Unit is conversed according to stored calls information searching B2, if in conversation then judge the emergency level of this time calling.The emergency level of supposing the conversation that this time of C0 calling and B2 are just carrying out is identical, and then searches the highest visible dispatching terminal of rank in this conversation of B2, finally finds A1;
