Actual system can simplify, and omits audio processing modules 40, sound card module 50 and real-time Transmission channel module 70.The information that this simplified system received can only be control information and fixing key information.The voice messaging that this simplified system sent is fixing optional some, can store several fixing voice messagings in PC in advance, and the voice messaging of these storages is anticipated into audio pack and carried out the packing processing of RTP/RTCP.When sending fixing voice messaging, UDP/IP reads fixing voice packet and packing transmission from the memory of PC.For example, the voice messaging of storage can be " please import the extension that you will dial ", " please import the outside line key that you will dial ", information such as " just a moment,please ".System or operator are according to these voice signal outputs of Information Selection of calling party's input.
The flow process of the system works of the calling exhalation of one embodiment of the invention or incoming call is described below in conjunction with Fig. 2:
At first enter step 100, console receipt of call request message.This step can be divided into following substep: network interface receives the call request message of UDP/IP encapsulation and carries out UDP/IP and unpacks; Packet after the internal agreement processing module unpacks UDP/IP carries out internal agreement and unpacks; Corn module finds it is call request message according to the message that receives.
Then enter step 110, console and incoming call side send out handshake information mutually.This step is in order to ensure the reliability of conversation, and whether the circuit of test call is reliable before conversation.
Then enter step 120, whether judgement shakes hands successful, if enter step 130, otherwise finishes.In this step, reliable if the success explanation both call sides of shaking hands all has been ready to the circuit conversing and converse, otherwise explanation circuit packet loss is serious, and can't normal talking.
In step 130, the IP console shows mutual information to the user.Then enter step 140.This step also can be divided into two sub-steps: corn module is handled the information of incoming call side; User interactive module explicit user interactive information.In the present embodiment, the IP console shows the message of incoming call, IP address and request user answer or refusal etc. on the interface by user interactive module.
In step 140, judge that whether the local user agrees conversation, if enter step 150, otherwise enters step 160.This step also can be divided into following two sub-steps: the user operates User Interface, for example clicks the button that representative is agreed the button of conversation or clicked the refusal conversation; Corn module process user operation information judges whether the user agrees conversation.
In step 150, local IP console sends agrees communication information.Then enter step 170.If corn module is judged the user and agreed conversation, then send to the opposite end and agree communication information by internal agreement processing module and Network Interface Module.This step needs affirmation mechanism, also promptly require incoming call side after receiving this message, to reply a confirmation, do not retransmit the agreement communication information if local IP console is received confirmation within a certain period of time, the agreement communication information is received by promptly local IP console assurance incoming call side.
In step 160, local IP console sends the refusal call message.If corn module judges that the user disagrees with conversation, then send the refusal call message to the opposite end by internal agreement processing module and Network Interface Module.This step needs affirmation mechanism, also promptly require incoming call side after receiving this message, to reply a confirmation, do not retransmit the refusal call message if local IP console is received confirmation within a certain period of time, refuse information is received by promptly local IP console assurance incoming call side.This incoming call flow process of the complete back of this step finishes.
In step 170, the local traffic platform is opened real-time Transmission passage and audio processing modules.This step, is opened audio processing modules information to the audio processing modules transmission and is realized to real-time Transmission channel module sendaisle management information by corn module.
Then enter step 180, the user converses.This step can be made up of following two sub-steps: send local voice messaging; The voice messaging of reduction far-end correspondent.Wherein send local voice messaging and also can be further divided into following substep: gather the voice of user's input and be converted to audio stream; To the audio stream formation audio pack of encoding and pack; Audio pack is carried out the RTP/RTCP packing; Network interface carries out the UDP/IP encapsulation to the RTP/RTCP bag and sends.The voice messaging of far-end correspondent of wherein reducing can be further divided into following substep: the packet that network interface receives the UDP/IP encapsulation also unpacks; Packet is carried out RTP/RTCP to unpack; Audio pack is unpacked and decoding is reduced to audio stream; Audio stream is reduced to voice signal.As can be seen, two sub-steps of step 180 are opposite on flow process.
Then enter step 190, judge whether that the local user finishes conversation.If enter step 210, otherwise enter step 200.This step is not to be realized by the IP console, adds for clear on the flowchart logic herein.
In step 200, receive the other side and finish call message.Then enter step 220.When conversation is finished by the other side's on-hook, the other side finishes to enter this step after call message is received by local IP console sending after the on-hook.
In step 210, local IP console sends and finishes call message.Then enter step 220.After being finished by local user's on-hook, conversation enters step 210.This step can be divided into following two sub-steps: user interface is sent the end calling order; Corn module responds this order and sends the end call message.This step also needs affirmation mechanism, promptly waits for a period of time if no confirmation is then retransmitted to guarantee that the other side receives the end call message.
In step 220, close the real-time Transmission passage and the audio processing modules of local IP console.This step is sent channel control signals by corn module and is closed the realization of real-time Transmission passage.
So far, this incoming call finishes.
When calling out exhalation, the workflow of IP console is similar with the workflow of calling out incoming call, distinguishes as follows:
Call request message is not to receive but transmission in step 100.This step is to be divided into following substep: the user sends call request by user interactive module; Corn module is sent call request message according to the request of receiving; The internal agreement processing module is carried out the internal agreement packing to call request message; The message bag of Network Interface Module after to inner protocol packing carries out the UDP/IP packing and sends.
The other side that shakes hands when mutual of step 110 is shaken hands instruction becomes the callee by incoming call side.
Judge in the step 140 be not whether the local user agrees conversation but whether remote subscriber agrees conversation.
Not to send message but receive message in the step 150 and 160, need to prove, in step 150, after receiving message, need to send an acknowledge message.
Need to prove, in the flow process that above incoming call is breathed out, protocol message of every reception, the reception and the UDP/IP that pass through Network Interface Module unpack, the internal agreement processing module unpack these several sub-steps of processing with corn module; Protocol message of every transmission all passes through corn module and sends, the packing of internal agreement processing module, and Network Interface Module carries out the UDP/IP packing and sends this several sub-steps.
The flow process of operator's searching user's information or ticket information is described below in conjunction with Fig. 3:
At first enter step 300, judge that whether the operator requires inquiry, if enter step 310, otherwise enters step 340.The operator sends search request by user interactive module to the IP console.
In step 310, judge whether to require real-time inquiry, if enter step 320, otherwise enter step 330.The IP console can be downloaded user profile and ticket information from Softswitch automatically every the regular hour generally speaking, if operator's needs is up-to-date information, then needs to force the IP console to inquire about in real time.Because download the up-to-date informational needs cost regular hour, if the operator wishes to see as early as possible the result, can not require real-time inquiry, directly check the historical data in the IP console.
In step 320, the IP console is downloaded from Softswitch and is wanted information inquiring.Then enter step 330.This step can have following substep: the inquiry submodule in the corn module sends the instruction of Query Information; The internal agreement processing module should be instructed packing; Network Interface Module is packaged as instruction the UDP/IP bag and sends to Softswitch; Network Interface Module receives the user profile of Softswitch transmission and carries out UDP/IP and unpacks; The internal agreement processing module unpacks; Inquiry submodule in the corn module is handled the Query Information that receives.
In step 330, show information inquiring by user interactive module.Information inquiring mainly contains two kinds here: user data information and ticket information.The user can further operate or handle the information that inquires, and for example prints ticket etc.
Then enter step 340, the IP console is regularly from user data information of Softswitch download and ticket information.In a preferred embodiment of the present invention, the IP console was downloaded user data information and ticket information every one minute from Softswitch.Then enter step 300.
These steps are gone round and begun again and are realized the workflow of user inquiring.
Need to prove, above-mentioned all flow processs, the control information that sends for every far-end of receiving is all returned an acknowledge message it is confirmed, if in the certain hour section, send do not receive the recipient in order side affirmation message then this control information need repeating transmission.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
