In a preferred embodiment of an embodiment of the present invention, above-mentioned mapping relations can be established by way of static, Then step 701 may include following sub-step:

Sub-step S11 determines the corresponding view networking number of registered virtual view networked terminals；

Sub-step S12, respectively it is described it is registered it is virtual depending on networked terminals distribute one carry out point-to-point communication with it Virtual pure tone frequency terminal；

Sub-step S13 is believed by the terminal that configuration file generates the view networking number and the virtual pure tone frequency terminal Binding relationship between breath.

In the concrete realization, static mode refers to that view networking number binding one of each virtual view networked terminals is pure The number of voice frequency terminal, relationship are one-to-one relationships.In practice, this mode can be used for regarding networking videophone Business, i.e. point to point call, XMCU can tied up depending on networked terminals and pure audio terminal room by modification configuration file to establish Determine relationship, wherein configuration file indicates that access terminal is pure tone frequency terminal.

Specifically, can be distributed for the corresponding view networking number of each registered virtual view networked terminals for it One carries out the virtual pure tone frequency terminal of point-to-point communication with it, and obtains the end message of the virtual pure tone frequency terminal, then, The binding relationship between view networking number and end message can be established by configuration file.

In one embodiment, as shown in the configuration file schematic diagram of Fig. 9, which may include virtual view connection ID (generally view networking number) number of network termination, the communication protocol Protocol of pure audio end-on, pure audio are whole The medium type media_attribute of the IP address address at end, ID sipid of pure tone frequency terminal, terminal, video code flow Bitrate, video resolution preferred_video_resolution, the letter such as the virtual address Mac vmmac for regarding networked terminals Breath, by configuration file, can be generated the binding relationship of these information.

It should be noted that as shown in figure 9, need to be written its in configuration file for H.323 agreement and correspond to IP address, Sipid can be set as 0.For Session Initiation Protocol, need to be written its corresponding sipid in configuration file, IP address can be set as 0。

In another preferred embodiment of the embodiment of the present invention, above-mentioned mapping can be established by dynamic mode and is closed System, then step 701 may include following sub-step:

Sub-step S21, receives the resource acquisition request that view networking Core server is sent, and the resource acquisition request includes The end message of internet pure tone frequency terminal；

Sub-step S22 then inquires idle virtual view if it is determined that the corresponding terminal of the end message is pure tone frequency terminal Networked terminals；

Sub-step S23 obtains the corresponding view networking number of virtual view networked terminals of the free time；

Sub-step S24 generates the binding relationship between the view networking number and the end message；

The binding relationship is stored in mapping table by sub-step S25.

In the concrete realization, dynamical fashion can be used for carrying out dynamic binding in Pamir convention business, release after the conference is over Put the resource of virtual view networked terminals.

Specifically, needing to add the type of pure tone frequency terminal when software meeting can be controlled depending on networking, agreement is docked, then The resource acquisition request that software sends out an application virtual terminal resource to XMCU can be controlled by passing through depending on networking Core server, the resource Acquisition request may include the end message of internet pure tone frequency terminal.

It, can be in the terminal information database of pre-registered pure tone frequency terminal after XMCU receives resource acquisition request The end message received is searched, if searching successfully, can be determined that the corresponding terminal of the end message is pure tone frequency terminal. At this point, XMCU can inquire the status information of all virtual view networked terminals, and determine that status information is the sky of idle state Not busy virtual view networked terminals, and the view networking number of the virtual view networked terminals of the free time is obtained, generate view networking number It is stored in mapping relations database with the binding relationship between the end message that receives, to be the pure audio terminal distribution One available view networked virtual terminal, when after the conference is over, can releasing the binding relationship, and the binding relationship is corresponding The virtual state depending on networked terminals be set as idle state, to discharge the resource of virtual view networked terminals.

Step 702, the view networking conference communication request that view networking Core server is sent is received, the view networking meeting is logical Letter request includes view networking number；

In the concrete realization, as shown in figure 8, when needing to access internet pure audio terminals joining the conference depending on networked terminals, depending on Networked terminals can send view networking conference communication request to view networking Core server, by view networking Core server by the view Networking conference communication request is sent to XMCU.Wherein, this may include virtual view networked terminals depending on networking conference communication request Depending on number of networking.

Step 703, the medium type of terminal corresponding with the view networking number is searched from preset mapping table；

After XMCU receives view networking conference communication request, view networking number is extracted from view networking conference communication request Code, and view networking number is searched in mapping table, if view networking number is found, from corresponding binding relationship The medium type media_attribute of middle acquisition and the terminal of view networked terminals access.

Step 704, if the medium type be pure audio type, determine the terminal for internet pure tone frequency terminal, And communication protocol corresponding with view networking number is obtained from the mapping table；

In one embodiment, if the medium type is audio type, the terminal with view networked terminals access is indicated Pure tone frequency terminal；If the medium type is audio+video type, indicate to regard with the sound of the terminal of view networked terminals access Frequency terminal.

If the terminal of the access is pure tone frequency terminal, the pure tone can be further obtained from corresponding binding relationship The corresponding communication protocol of frequency terminal.

As pure tone frequency terminal, which may include H.323 agreement and/or Session Initiation Protocol.

Step 705, view networking conference communication request is carried out by protocol conversion using the communication protocol, is called Request；And the call request is sent to corresponding internet pure tone frequency terminal；

In the concrete realization, XMCU is a protocol conversion gateway, and the V2V protocol conversion that view can be networked is at pure audio Therefore the H.323/SIP agreement that terminal is supported after XMCU obtains the communication protocol of pure tone frequency terminal, can use the communication Agreement will be converted into internet H.323/SIP call request depending on networking conference communication request.

Wherein, the audio/video encoding/decoding format that H.323/SIP can be supported in agreement with carried terminal, so as to meeting, both sides can To negotiate and reach an agreement, therefore, H.323/SIP which carries first that view networked terminals can identify in call request Audio coding formats and the first audio decoder format, so that pure tone frequency terminal can know the view networked terminals of Correspondent Node Code/decode format.

After XMCU will be converted into call request depending on networking conference communication request using communication protocol, which can be asked It asks and is sent to pure tone frequency terminal, with calling Internet pure audio terminals joining the conference.

Step 706, the call message that the internet pure tone frequency terminal returns is received；

After pure tone frequency terminal receives call request, can returning to internet to XMCU, H.323/SIP call disappears Breath, the call message can carry the second audio coding formats that the pure tone frequency terminal can identify and the second audio solution Code format.

Step 707, judge whether second audio coding formats and the second audio decoder format are specified coding Mode and decoding process；If it is not, thening follow the steps 708；If so, thening follow the steps 709；

Step 708, determine session establishment failure；

Step 709, the communication session between the virtual pure tone frequency terminal and the internet pure tone frequency terminal is established, and Confirming call message is generated, the confirming call message is sent to by internet pure audio end by the virtual pure tone frequency terminal End, and, conference communication response message is generated, is sent the conference communication response message by the virtual view networked terminals To view networking Core server；Continue to execute step 710；

XMCU receives internet H.323/SIP after call message, can further judge to regard networked terminals with The audio coding decoding format of internet terminal whether intercommunication, and, after transcoding can intercommunication, if intercommunication, session establishment success, If not intercommunication, session establishment failure.

In the concrete realization, XMCU can be by judging second audio coding formats and the second audio decoder format is No coding mode and decoding process to specify, to determine to be depending on the audio coding decoding format of networked terminals and internet terminal No intercommunication, and, it can intercommunication after transcoding.

Specifically, only supporting AAC (Advanced Audio depending on networked terminals and the virtual audio coding depending on networked terminals Coding, Advanced Audio Coding) format, Video coding only supports H.264 format.And the audio of most internet terminals is compiled Code all supports that G.711 a kind of (audio coding mode formulated by International Telecommunication Union (ITU-T)) format, Video coding are supported H.264 H.323/SIP format, therefore, all virtual pure tone frequency terminals provide in calling Internet pure tone frequency terminal in message G.711 the audio of negotiation only has, if determining that the pure tone frequency terminal does not prop up from the call message that pure tone frequency terminal returns It holds G.711, then session establishment fails, depending on networked terminals without farad pure audio terminals joining the conference, if supporting that G.711 session is built It stands successfully, XMCU needs carry out transcoding between AAC and G.711 audio, to guarantee both sides' audio intercommunication.

After the success of the session establishment of the virtual pure tone frequency terminal and the internet pure audio terminal room, XMCU can To generate internet H.323/SIP confirming call message, H.323/SIP the internet is called really by virtual pure tone frequency terminal Recognize message and be sent to internet pure tone frequency terminal, to inform the success of the internet pure tone frequency terminal session establishment, the internet is pure Voice frequency terminal membership.

Meanwhile XMCU can also generate conference communication response message, be rung the conference communication by virtually regarding networked terminals Message is answered to be sent to view networking Core server, by the conference communication response message is sent to view connection depending on networking Core server Network termination, to inform view networked terminals session establishment success, the internet pure tone frequency terminal membership.

Step 710, when receiving the video/audio that view networking Core server is sent, the video/audio is pressed According to the communication Protocol Conversion at audio data, and the audio data is sent to the internet pure tone frequency terminal；

Step 711, when receiving the audio data that the internet pure tone frequency terminal is sent, the audio data is pressed According to it is preset converted depending on networking protocol after be sent to view networking Core server, and to the view networking Core server send out Send preset video flowing.

After session establishment success, the audio, video data association that can start conference process turns over journey.As shown in figure 8, view connection Network termination and be view networking audio, video data packet depending on what is transmitted between networking Core server, view are networked Core server and XMCU It is virtual depending on transmitted between networked terminals be also view networking audio, video data packet, the virtual pure tone frequency terminal and internet of XMCU What is transmitted between pure tone frequency terminal is pure audio data packet.

Specifically, when XMCU receives the video/audio that view networking Core server is sent, it can be by the video and audio The communication protocol that data can be identified according to pure tone frequency terminal is converted into audio data, and the audio data is sent to internet Pure tone frequency terminal.

It, can be by the audio data according to default when XMCU receives the audio data of internet pure tone frequency terminal transmission Be converted into being sent to view networking Core server depending on networking data packet depending on networking protocol (such as V2V agreement), networked core by view Server sends the view networking data packet to depending on networked terminals.

Meanwhile in order to avoid the I frame request message that other conference terminals are sent, virtual on XMCU can be with depending on networked terminals Preset video flowing is sent to view networking Core server, it is by regarding networking Core server that the video stream is whole to view networking End, to inform that attend a meeting end-on is pure tone frequency terminal, the terminal that prevents from attending a meeting ceaselessly sends I frame request message.In addition, should May include I frame information in video flowing, terminal of attending a meeting can normally decode display based on the I frame information after receiving video flowing, Therefore I frame request message would not be sent, prevents XMCU from persistently receiving I frame request message and carries out logical process.
