Below in conjunction with Fig. 4 to Figure 10, the technical scheme that a plurality of single lines of realizing based on command dispatching system of the present invention are conversed 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, the UI business module is deployed in the dispatching desk side, i.e. the client of command scheduling, its responsibility mainly are to the calling interactive operation of dispatcher's shielding with dispatch server.The dispatcher provides the interface to carry out call operation by the UI business module.The dispatcher is when initiating a plurality of single-party call, and the UI business module can keep current conversation automatically, if conversation keeps successfully, just really initiates the calling that the dispatcher asks.
Call Control Block is deployed in the dispatch server side, and its responsibility mainly is that the call request of resolution scheduling platform initiation, the business of calling relation are judged and state machine.Call Control Block carries out decode operation to the call instruction that dispatching desk passes over, search this calling and whether have other related talk business, if exist, the branch that then processes by service logic judgement conversation is directly and soft switchcall server is mutual or and media apparatus interaction.Call Control Block is to use Session Initiation Protocol to communicate with soft switchcall server or media apparatus interaction the time, and state machine becomes sip message with the instruction translation of business module, is pushed to corresponding target.
The responsibility of media server mainly is 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 resource type and the entity on the dispatch server of request, if consult successfully, then media server is this scheduling entity allocation medium resource.In keeping operation, media server is scheduling entity allocation medium resource, and according to the result of SDP negotiation, the audio medium stream of maintenance is sent to the destination; In telephone operation, the voice call data flow between two scheduling entity is forwarded to the target of opposite end through the media entity.
Fig. 5 shows the signal circulation schematic diagram that utilizes according to an embodiment of the invention command dispatching system to realize a plurality of single line conversations; The step that numeral among the figure on the arrow line should operate, and the people that letter representation is called out, A represents Field Force A, B represents Field Force B.
As shown in Figure 5, the example of 2 single-party calls of initiating for the dispatcher, its step is as follows:
Steps A 1, the dispatcher is by the calling of the initiation of the UI business module in the dispatching desk to Field Force A.
Steps A 2, UI business module find that current attending a banquet do not participate in other conversations, directly send call request to dispatch server.
Steps A 3, the Call Control Block of dispatch server are received the request of setting up conversation, find to attend a banquet current any conversation that do not participate in, and directly call request are translated as sip message, and mutual with soft switchcall server, carry out the conversation 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 conversation 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 to the SIP signaling.
Steps A 4, after soft switchcall server is received the SIP request, process seat call Field Force A, the soft switchcall server feedback is called out the result to dispatch server, dispatch server is calling out result feedback to the UI business module, the UI business module is according to calling out the result, show Calls situation on the interface, and dispatcher and Field Force A converse.
Following example is not finish the A with the Field Force, does not use in other physical circuit situations of IP phone of attending a banquet simultaneously, use original physics talk line to finish to keep Field Force A and with the conversation of Field Force B.
Step B1, dispatcher need and another Field Force B converse (call out the Field Force or answer Field Force's incoming call).The dispatcher operates at dispatching desk, Field Force B is initiated to set up the request of conversation.
Step B2, UI business module current being in other conversations of finding to attend a banquet sends message that current talking keeps to dispatch server.
After step B3, dispatch server obtained the media information of phone by soft switchcall server, Call Control Block entered the media processing flow process.
Step B4, dispatch server are by the soft switchcall server request and obtain and attend a banquet and the media information of Field Force A.
Step B5, Call Control Block is take the scheduling entity of attending a banquet as the unit, and to the request of state machine module transmission media resource application, state machine module is translated into the SIP signaling to media resource application request, send to media server, carry out media information (SDP) with media server and consult.
Step B6 and B7, media server distribute the media resource entity of attending a banquet according to negotiation result for attending a banquet; And the result returned dispatch server, state machine returns to Call Control Block to request results, Call Control Block for and the opposite end number of attending a banquet related (Field Force A) apply for media playback resources (holding tone).Media server is Field Force A allocation medium resource entity according to negotiation result, and the Field Force is sent the Media Stream that keeps audio frequency.
Step B8, dispatch server returns to dispatching desk to result.Dispatching desk sends the request of conversing B with the Field Force to dispatch server after receiving and keeping success message again.
Step B9, Call Control Block returns the result of maintenance operation to the UI business module, the UI business module also sends to dispatch server to the call request encapsulation of calling out Field Force B, and dispatch server is by the soft switchcall server request and obtain the media information of Field Force B.Call Control Block enters the media processing flow process, and Call Control Block is take Field Force B as the scheduling entity unit, and to the request of state machine transmission media resource association, dispatch server and media server are for the negotiating media of Field Force B.
Step B10, consult successfully after, media server adds the media resource entity of attending a banquet to this Field Force.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 other Field Force B.
Step B11, state machine module returns to Call Control Block to the result, calls out control the result is returned to the UI business module, and the UI business module is by the conversation of interface display the second circuit.Thereby make dispatcher and Field Force B set up voice call.
Fig. 6 shows dispatcher according to an embodiment of the invention and initiates flow example figure to the calling of Field Force A by dispatching desk.
Step 504 judges whether the phone of attending a banquet exists other related talk business.If judged result is yes, enter step 508; If the determination result is NO, enter step 506.
Step 506 is judged the still uncorrelated conversation of attending a banquet, and directly encapsulates the data that the Field Force calls out.
Step 512 sends message to dispatch server.
Fig. 7 shows according to an embodiment of the invention the dispatch service end to the process chart of call request; In the drawings, call request singly is not the calling that dispatching desk is initiated, and comprises that the Field Force calls out the request of attending a banquet.
Step 604 is resolved call request, and judges to attend a banquet whether be in the conversation, if the determination result is NO, enter 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 the media processing flow process.
Step 610 keeps original conversation.
Step 616 is attended a banquet and is set up conversation with target person.
Fig. 8 shows the speech sample figure that attends a banquet according to an embodiment of the invention with Field Force B.
As shown in Figure 8, this moment, Field Force A broke away 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 be in the holding tone state.And for attending a banquet and Field Force B, their conversation is through same media entity, and media server pushes their speech data according to separately media information, attends a banquet and Field Force B normal talking.
