Below in conjunction with Fig. 4 to Figure 10, the technical scheme of the multiple single line calls that realize based on command dispatching system of the present invention is elaborated.
As shown in Figure 4, the command dispatching system of embodiments of the invention mainly comprises: UI business module, Call Control Block and media server.
Wherein, UI business module is deployed in dispatching desk side, i.e. the client of command scheduling, and its responsibility is mainly the calling interactive operation with dispatch server to dispatcher's shielding.Dispatcher provides interface to carry out call operation by UI business module.Dispatcher is in the time initiating multiple single-party call, and UI business module can keep current call automatically, if call keeps successfully, just really initiates the calling that dispatcher asks.
Call Control Block is deployed in dispatch server side, and its responsibility is mainly the call request of resolution scheduling platform initiation, business judgement and the state machine of calling relation.The call instruction that Call Control Block passes over dispatching desk is carried out decode operation, search this calling and whether have other associated talk business, if existed, judge by service logic the branch that call is processed, be directly and soft switchcall server alternately or and media apparatus interaction.Call Control Block, when with soft switchcall server or media apparatus interaction, is to use Session Initiation Protocol to communicate, and the instruction translation of business module is become sip message by state machine, is pushed to corresponding target.
The responsibility of media server is mainly to process the media resource request that scheduling sends over, the distribution of management of media resource.Media server module is resolved request.Media server carries out media negotiation (SDP) according to the entity on resource type and the dispatch server of request, if consulted successfully, media server is this scheduling entity allocation medium resource.In maintenance operation, media server is scheduling entity allocation medium resource, and according to the result of SDP negotiation, the audio medium stream keeping is sent to destination; In telephone operation, the voice call data flow between two scheduling entity is forwarded to the target of opposite end through media entity.
Fig. 5 shows the signal circulation schematic diagram that utilizes according to an embodiment of the invention command dispatching system to realize multiple single line calls; The step of this operation of numeral in figure on arrow line, and the people that letter representation is called out, A represents Field Force A, B represents Field Force B.
As shown in Figure 5, be the example of 2 single-party calls that dispatcher initiates, its step is as follows:
Steps A 1, dispatcher initiates the calling to Field Force A by the UI business module in dispatching desk.
Steps A 2, UI business module finds that current attending a banquet do not participate in other calls, directly sends call request to dispatch server.
Steps A 3, the Call Control Block of dispatch server is received the request of setting up call, finds to attend a banquet current any call that do not participate in, and directly call request is translated as to sip message, and mutual with soft switchcall server, carries out call Establishing process.Its detailed process is: dispatch server is received the information of UI business module, and resolves, and knows it is call request, transmits the information to Call Control Block.Call Control Block enters calling control flow according to business information, the discovery still uncorrelated call of attending a banquet, directly encapsulation messages is pushed to state machine, state machine is received call instruction, instruction is resolved, and be the allocation schedule entity of attending a banquet, and according to call request structure SIP signaling, state machine sends soft switchcall server SIP signaling.
Steps A 4, soft switchcall server is received after SIP request, process seat call Field Force A, soft switchcall server feedback is called out result to dispatch server, dispatch server is calling out result feedback to UI business module, UI business module according to call out result, show Calls situation on interface, dispatcher and Field Force A converse.
Following example is not finish the A with Field Force, does not use simultaneously and attends a banquet in other physical circuit situations of IP phone, use original physics talk line to complete to keep Field Force A and with the call of Field Force B.
Step B1, dispatcher needs and another Field Force B converse (call out Field Force or answer Field Force's incoming call).Dispatcher operates at dispatching desk, Field Force B is initiated to set up to the request of call.
Step B2, UI business module find attend a banquet current in other call in, send current talking keep message to dispatch server.
Step B3, dispatch server obtains by soft switchcall server after the media information of phone, and Call Control Block enters media processing flow process.
Step B4, dispatch server is by soft switchcall server request and obtain and attend a banquet and the media information of Field Force A.
Step B5, Call Control Block, taking the scheduling entity of attending a banquet as unit, sends the request of media resource application to state machine module, state machine module is translated into SIP signaling media resource application request, send to media server, carry out media information (SDP) with media server and consult.
Step B6 and B7, media server, according to negotiation result, distributes the media resource entity of attending a banquet for attending a banquet; And result is returned to dispatch server, and state machine returns to Call Control Block request results, and Call Control Block is and the opposite end number of attending a banquet associated (Field Force A) application media playback resources (holding tone).Media server, according to negotiation result, is Field Force A allocation medium resource entity, and Field Force is sent to the Media Stream that keeps audio frequency.
Step B8, dispatch server returns to dispatching desk result.Dispatching desk is received and is kept after success message, then sends the request of conversing B with Field Force to dispatch server.
Step B9, Call Control Block returns and keeps the result of operation to UI business module, UI business module encapsulates and sends to dispatch server the call request of calling out Field Force B, and dispatch server is by soft switchcall server request and obtain the media information of Field Force B.Call Control Block enters media processing flow process, and Call Control Block, taking Field Force B as scheduling entity unit, sends the request of media resource association to state machine, and dispatch server and media server are for the negotiating media of Field Force B.
Step B10, after consulting successfully, media server adds this Field Force the media resource entity of attending a banquet.The voice of two phones are with RTP(Real-time Transport Protocol, real time transport protocol) transmission, and centered by the resource of attending a banquet of media server, be forwarded to the phone of another Field Force B.
Step B11, state machine module returns to Call Control Block result, calls out to control result is returned to UI business module, and UI business module is by the call of interface display the second circuit.Thereby make dispatcher and Field Force B set up voice call.
Fig. 6 shows the flow example figure that dispatcher initiates the calling to Field Force A by dispatching desk according to an embodiment of the invention.
Step 502, dispatcher initiates the calling to Field Force A by UI business module.
Step 504, judges whether the phone of attending a banquet exists other associated talk business.If judged result is yes, enter step 508; If judged result is no, enter step 506.
Step 506, judges the still uncorrelated call of attending a banquet, and directly encapsulates the data that Field Force calls out.
Step 508, judgement is attended a banquet and has been set up other calls, keeps ongoing call.
Step 510, the data that encapsulation call keeps.
Step 512, sends message to dispatch server.
Fig. 7 shows the process chart of dispatch service end to call request according to an embodiment of the invention; In the drawings, call request is not singly the calling that dispatching desk is initiated, and comprises that Field Force calls out the request of attending a banquet.
Step 602, dispatch server is received call request.
Step 604, resolves call request, and whether judgement attend a banquet in call, if judged result is no, enters step 606; If judged result is yes, enter step 608.
Step 606, enters call flows, dispatch server directly and soft switchcall server carry out alternately.
Step 608, enters media processing flow process.
Step 610, keeps original call.
Step 612, dispatch server and media server are held consultation.
Step 614, after consulting successfully, media server is target person and the media entity associated of attending a banquet.
Step 616, attends a banquet and sets up call with target person.
Fig. 8 shows the speech sample figure attending a banquet according to an embodiment of the invention with Field Force B.
As shown in Figure 8, now Field Force A has departed from the media resource entity of attending a banquet, and the RTP that media server transmits separately holding tone wraps the phone to Field Force A, makes A in holding tone state.And for attending a banquet and Field Force B, their call is through same media entity, media server, according to media information separately, pushes their speech data, attends a banquet and Field Force B normal talking.
With above-mentioned the same, allow the opposite end number of conversing on media server, depart from the media entity of attending a banquet for the people's such as follow-up Field Force C, D calling procedure, and to its application media playback resource.Put after holding tone at the opposite end number original call, by Call Control Block and media server, complete follow-up personnel and join the media resource entity of attending a banquet, realize the call of attending a banquet with follow-up personnel.
Fig. 9 shows dispatcher according to an embodiment of the invention and fetches the flow chart of the call in hold mode by dispatching desk.
As shown in Figure 9, dispatcher fetches the example of call, is equally to be initiated request and do not used IP phone by dispatching desk interface.Dispatcher fetches the call with Field Force A, and this operation does not need Field Force A ring again, and step is as follows.
