Fig. 3 is the flow chart of the way of recording one execution mode of the present invention, and present embodiment is the flow chart of voice switching device end, comprising:
Step S101: voice switching device receives the recording request from the first communication terminal, and the first communication terminal is communicated by voice switching device with other communication terminal.
Voice switching device is a kind of network equipment forwarded for voice telecommunication number, Main Function be process user registration, calling, out relaying, create meeting-place and the instruction interaction etc. with recording server.
First communication terminal is the communication terminal of initiatively initiating recording request, and other communication terminal is the communication terminal participating in Recording Process except the first communication terminal.When the videoconference by voice switching device creates communicates, other communication terminal generally has two at least; When carrying out point-to-point communication by voice switching device, other communication terminal is one.
When first communication terminal sends recording request to voice switching device, voice switching device receives the recording request from the first communication terminal, and wherein, the first communication terminal is communicated by voice switching device with other communication terminal.
Step S102: voice switching device, when receiving recording request, carries out audio mixing to the Media Stream from the first communication terminal of current reception and the Media Stream from other communication terminal, and the Media Stream generated by audio mixing is preserved in the buffer as the first Media Stream.
First Media Stream was voice switching device before the startup recording response receiving recording server, the Media Stream generated after the Media Stream from the first communication terminal and the Media Stream from other communication terminal are carried out stereo process.
Voice switching device is before the startup recording response receiving recording server, and recording server is also for recording is not ready.But the first communication terminal and other communication terminal start session, the first Media Stream is preserved in the buffer by voice switching device, the recording server that can prevent loss be recording ready before Media Stream, wherein, buffer memory creates in advance.
Step S103: recording server is added comprising in the meeting-place of the first communication terminal and other communication terminal of voice switching device establishment by voice switching device.
Recording server obtains Media Stream, realizes the equipment of user recording.After voice switching device receives the recording request from the first communication terminal, need recording server to be added in meeting-place can realize recording.Meeting-place is that voice switching device creates, and comprises the first communication terminal and other communication terminal.If peer to peer session, after voice switching device receives the recording request of the first communication terminal, voice switching device creates meeting-place, adds in meeting-place by the first communication terminal and other communication terminal; If videoconference, meeting-place created before videoconference starts, and was the meeting-place of videoconference, after voice switching device receives the recording request of the first communication terminal, did not need to create meeting-place again.
Can be specifically: voice switching device sends Invite message to signal server, recording server is invited to add meeting-place, signal server selects suitable recording server in recording server cluster, and the IP address of recording server is replied to voice switching device in 200OK message, recording server is added meeting-place by voice switching device.
Signal server is for the treatment of from the signaling of voice switching device and the equipment of record command, and that is responsible between recording server is mutual simultaneously.
Wherein, voice switching device is the voice switching device of IP based network, and signal server is Session initiation Protocol SIP signal server.Certainly, signal server can also be the signal server of H.323 agreement, does not limit at this.
Certainly, the function that signal server carries out Signalling exchange also can be integrated on recording server, make voice switching device directly and recording server carry out the mutual of signaling.
Step S104: voice switching device sends startup recording to recording server and asks and the startup recording response receiving recording server transmission.
Can be specifically that, after recording server adds meeting-place, voice switching device sends to recording server and starts recording request, so that recording server is recording ready (as being this recording reserved recording resource).As, the specific implementation of step S104 is: voice switching device sends SIP INFO to signal server, notice recording server starts recording, the message that notice recording server starts recording is sent to recording server by signal server, after signal server receives the startup recording response of recording server, by 200OK message, the startup of this recording server recording response is sent to voice switching device, voice switching device, after the startup recording response receiving recording server, can determine recording server for recording is ready.
Can also be specifically adding in the process in meeting-place by recording server, signaling mutual during by recording server being added meeting-place sends and starts recording request and start recording response.As, the specific implementation of step S104 is: the SIP INVITE that voice switching device adds meeting-place by invitation recording server carries startup record command, the message that notice recording server starts recording is sent to recording server by signal server, and after the startup recording response receiving recording server, by the 200OK message of SIP INVITE, the startup of this recording server recording response is sent to voice switching device, namely voice switching device completes the process this recording server being added meeting-place after receiving this 200OK message, and determine recording server for recording is ready.
Step S105: voice switching device is after the startup recording response receiving recording server, audio mixing is carried out to the Media Stream from the first communication terminal of current reception and the Media Stream from other communication terminal, and using audio mixing generate Media Stream as the second media stream to recording server.
Second Media Stream is voice switching device after the startup recording response receiving recording server, the Media Stream generated after the Media Stream from the first communication terminal and the Media Stream from other communication terminal are carried out stereo process.
Voice switching device is after the startup recording response receiving recording server, and recording server has been carried out recording for recording and prepared.The Media Stream from the first communication terminal of current reception and the Media Stream from other communication terminal are carried out audio mixing by voice switching device, now, using audio mixing generate Media Stream as the second media stream to recording server.
Step S106: voice switching device by receive start recording response before preserve the first media stream in the buffer to recording server, so that recording server carries out mergings recording to the first Media Stream and the second Media Stream.
Within the time that recording server is not ready for recording, first Media Stream is preserved in the buffer, complete Media Stream is obtained for the ease of recording server, the first Media Stream preserved in the buffer sends to recording server by voice switching device, records so that recording server carries out merging to the first Media Stream and the second Media Stream.Step S106 specifically can have multiple implementation, and e.g., voice switching device sends the first Media Stream and the second Media Stream simultaneously, and the first Media Stream and the second Media Stream carry out merging and be recorded as a recording file by recording server; And for example, voice switching device first sends the second Media Stream and sends the first Media Stream again, and the first Media Stream and the second Media Stream are recorded as a recording file by recording server respectively, and these two recording files are merged into a recording file.
Consult Fig. 4, the way of recording of the present invention also comprises:
Step S107: voice switching device creates buffer memory when receiving recording request.
Buffer memory refers to temporary file exchange area, has the access rate be exceedingly fast, and it is the buffer between storage inside and extraneous interface.
Wherein, buffer memory is fifo fifo buffer memory.FIFO buffer memory refers to when carrying out read operation to buffer memory, and the data be first written in buffer memory are first read out.In this way, automatically buffer memory can be managed.
Voice switching device creates buffer memory when receiving recording request.Such as: can be create after the recording request receiving the first communication terminal.Certainly, also can be created before the recording request receiving the first communication terminal, not limit at this.
Step S108: voice switching device stops the Media Stream being generated by audio mixing to preserve in the buffer when receiving and starting recording response.
After the startup recording response receiving recording server, recording server is for recording is ready, therefore, voice switching device can stop the Media Stream generating after stereo process to preserve in the buffer, is directly sent as the second Media Stream to recording server by the Media Stream generated after stereo process.Like this, the memory space wasting buffer memory can be avoided.
Wherein, the media band in the first Media Stream has sequence number to identify, so that recording server identifies the media bag recorded in chronological order in the first Media Stream according to sequence number.
Wherein, Media Stream is realtime transmission protocol RTP Media Stream.
The present invention is before the startup recording response receiving recording server, and the first Media Stream generated after stereo process is preserved in the buffer by voice switching device; After the startup recording response receiving recording server, the second Media Stream generated after stereo process sends to recording server by voice switching device; The first Media Stream preserved in the buffer sends to recording server by voice switching device, records so that recording server carries out merging to the first Media Stream and the second Media Stream.In this way, the recording server that can prevent loss be recording ready before recording, thus complete recording can be obtained.
Consult Fig. 5, Fig. 5 is the flow chart of the another execution mode of the way of recording of the present invention, and present embodiment is the flow chart of recording server end, comprising:
Step S301: recording server adds comprising in the meeting-place of the first communication terminal and other communication terminal of voice switching device establishment, and the first communication terminal is communicated by voice switching device with other communication terminal.
Recording server obtains Media Stream, realizes the equipment of user recording.Voice switching device is a kind of for the voice telecommunication number network equipment forwarded.First communication terminal is the communication terminal of initiatively initiating recording request, and other communication terminal is the communication terminal participating in Recording Process except the first communication terminal.When the videoconference by voice switching device creates communicates, other communication terminal generally has two at least; When carrying out point-to-point communication by voice switching device, other communication terminal is one.Wherein, the first communication terminal is communicated by voice switching device with other communication terminal.
Step S302: recording server receives the startup recording request of voice switching device transmission and starts to voice switching device transmission response of recording.
After recording server adds meeting-place, receive the startup recording request that voice switching device sends, the startup recording request that now recording server reception voice switching device sends, and send startup recording response to voice switching device.
Step S303: after sending to voice switching device and starting recording response, recording server receives from the first Media Stream of voice switching device and the second Media Stream.
Second Media Stream is voice switching device after the startup recording response receiving recording server, the Media Stream generated after the Media Stream from the first communication terminal and the Media Stream from other communication terminal are carried out stereo process.After send startup recording response to voice switching device, recording server is ready for recording, and now, recording server reception is from the second Media Stream of voice switching device.
First Media Stream was voice switching device before the startup recording response receiving recording server, the Media Stream that voice switching device generates after the Media Stream from the first communication terminal and the Media Stream from other communication terminal are carried out stereo process.First Media Stream is preserved in the buffer in advance, until recording server be recording ready after, can receive voice switching device send preservation the first Media Stream in the buffer.
Step S304: recording server carries out merging to the first Media Stream and the second Media Stream and records.
Recording server carries out merging to the first Media Stream and the second Media Stream and records.As, voice switching device sends the first Media Stream and the second Media Stream simultaneously, and the first Media Stream and the second Media Stream carry out merging and be recorded as a recording file by recording server; And for example, voice switching device first sends the second Media Stream and sends the first Media Stream again, and the first Media Stream and the second Media Stream are recorded as a recording file by recording server respectively, and these two recording files are merged into a recording file.
After recording server of the present invention receives the first Media Stream and the second Media Stream, merging is carried out to the first Media Stream and the second Media Stream and records.In this way, the recording server that can prevent loss be recording ready before recording, thus complete recording can be obtained.
