The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed.
Before introducing the method provided by the embodiment of the present application, an audio and video conference system provided by the embodiment of the present application is introduced. Fig. 1 is a system architecture diagram of an audio and video conference system according to an embodiment of the present application. As shown in fig. 1, the audio/video conference system includes a plurality of public network interphones, a POC server, a gateway server, an audio/video conference server, and an audio/video conference access terminal.
And the public network interphone is connected with the POC server through the second interface gateway. Illustratively, the second interface gateway may be a HyPTTGateway hardware device. The HyPTTGateway is internally provided with a POC client account number, and the POC client account number is logged in to realize interconnection with a POC server. And the HyPTTGateway is provided with a radio frequency unit which is communicated with the public network interphone.
And the POC server and the audio and video conference server are respectively connected with the gateway server. The gateway server as a 'transfer station' can realize the intercommunication between a POC server (POC system) and an audio and video conference server (SIP system). And the audio and video conference server is connected with the plurality of audio and video conference access ends through the first interface gateway.
The following briefly describes each apparatus. The public network interphone is also called a card interphone, and is a technology for realizing talkback communication by transmitting voice information through a data channel of mobile phone network information. The public network trunking interphone generally has the functions of calling, group calling communication and the like of the current working group, and some public network trunking interphones are provided with the function of dialing the telephone. The public network walkie-talkie generally adopts a half-duplex communication mode, that is, a Time Division Multiple Access (TDMA) mode is adopted for communication. Specifically, the time is divided into periodic frames, each frame is divided into a plurality of time slots, and information is transmitted by using the time slots. In one time slot, only one public network interphone is allowed to receive or send voice information, which results in that the information receiving and sending of a plurality of public network interphones cannot be carried out simultaneously, and only one public network interphone is allowed to send voice in one period, so that the communication efficiency of the public network interphones is severely limited. Moreover, the public network interphones in a certain range all utilize time slots to transmit information, and one time slot only specially used for one public network interphone can normally communicate, so that information interference is easily caused. Therefore, in order to improve the communication efficiency of the public network interphones, the public network interphones can be connected into the audio and video conference system, and the audio and video conference system is used for scheduling a plurality of public network interphones. Therefore, the plurality of public network interphones can simultaneously send voice information to the audio and video conference system, and then conference participants of the audio and video conference send voice instruction information to command the transmission of the voice information. Therefore, the public network interphone can achieve the purpose of simultaneously sending voice at the same time, can also avoid interference and improve the communication efficiency of the public network interphone.
The following describes a communication process of uniformly scheduling public network interphones by participants (audio and video conference access ends) of an audio and video conference. Based on the network architecture shown in fig. 1, when the public network interphone sends out the voice information, the POC server connected to the public network interphone can receive the voice information sent by the multiple public network interphones at the same time, and then the POC server sends the voice information to the gateway server, and then the gateway server forwards the voice information to the audio and video conference server. Therefore, the public network interphones are accessed into the audio and video conference provided by the audio and video conference server through the POC server and the gateway server, and the plurality of public network interphones can be communicated with the audio and video conference access end simultaneously. Therefore, the public network interphone can send the voice information to the audio and video conference access end, and the audio and video conference access end can also output the voice instruction information (scheduling instruction) to the public network interphone.
Among other things, POC servers provide push-to-talk over cellular services that utilize the packet-switched capabilities of a wireless data network for voice transmission, which is not limited by geographic location. The POC server may control a plurality of public network interphones connected thereto. When a plurality of public network interphones send out the session request simultaneously, POC server can receive the speech information that each public network intercom sent simultaneously. For example, the POC client embedded in HyPTTGateway may perform compression encoding on the voice information, and then upload the compression-encoded voice information to the POC server.
The gateway server is used as the access of the audio and video conference server to access the on-site conference system on one hand, and is used as the proxy transfer of the voice packet sent by the POC server on the other hand. Generally, the audio/video conference server is a Session Initiation Protocol (SIP) system, and therefore, the gateway server mainly functions to interconnect and intercommunicate the POC system and the SIP system.
After the audio/video conference server receives the voice packet sent by the POC server, it needs to distribute the voice information to each audio/video conference access terminal participating in the conference video, and complete transmission of the uplink information (voice information). Similarly, when each audio/video conference access end participating in the conference video needs to send the voice instruction information to the public network interphone, the audio/video conference server can obtain the voice instruction information, then the audio/video conference server sends the voice instruction information to the gateway server, then the gateway server sends the voice instruction information to the POC server, and then the POC server instructs the public network interphone connected with the POC server to play the voice instruction information, so that the transmission of downlink information (voice instruction information) can be completed. Therefore, the public network interphone can be smoothly connected into the audio and video conference system, and the purpose that the public network interphone simultaneously sends voice in the same period is achieved.
Based on the system architecture, fig. 2 is a schematic flow chart of a method for joining an audio and video conference in a public network interphone according to an embodiment of the present application. As shown in fig. 2, the method includes:
201. and the audio and video conference access end sends the voice instruction information to the audio and video conference server.
When the public network interphone is accessed to the audio and video conference, the public network interphone needs to be uniformly scheduled by the audio and video conference access end and receives voice instruction information sent by the audio and video conference access end. The voice instruction information is used for controlling the communication process of the public network interphone. Because the audio and video conference system and the public network interphone system are incompatible, other forwarding devices are needed to realize the intercommunication between the two systems. Therefore, when the audio and video conference access terminal issues the voice instruction information, the voice instruction information needs to be sent to the audio and video conference server first, and then the voice instruction information is forwarded through the audio and video conference server.
202. And the audio and video conference server encodes the voice instruction information.
The audio and video conference server is used for providing an audio and video conference system and is connected with the audio and video conference access end through the first interface gateway. It can be understood that the access terminals of the audio and video conference of multiple parties can be simultaneously added into the audio and video conference, and when one party sends voice, other parties can receive the voice information. The existing audio and video conference provides a communication mode with multiple modes, and comprises that a plurality of audio and video conference access terminals can simultaneously send voice information, only some parties send the voice information, a plurality of persons receive the voice information simultaneously, a specific party receives the voice information and the like. Therefore, when the public network interphone is successfully accessed into the audio and video conference server, the audio and video conference access ends can uniformly schedule the communication of the public network interphone, so that the public network interphone can simultaneously communicate, and the aim that the communication of the public network interphone is not interfered any more can be fulfilled.
It will be appreciated that POC servers for directly managing public network interphones provide POC systems, whereas audio video conferencing systems are typically SIP systems. Therefore, it is necessary to use coding techniques to achieve network interworking. The audio and video conference server needs to encode the voice instruction information and then forward the encoded voice instruction information.
203. And the audio and video conference server sends the coded voice instruction information to the gateway server.
After the audio/video conference server encodes the voice instruction information, the encoded voice instruction information needs to be sent to the gateway server. The gateway server is used as a transfer station of the voice instruction information, and can transmit the voice instruction information to the POC server, so that the purpose of accessing the public network interphone to the audio and video conference is achieved. The gateway server is used for solving the intercommunication problem between the POC server and the audio and video conference server. Since the POC server is a POC system and the audio and video conference server is an SIP system, the POC server and the audio and video conference server are directly connected and cannot be compatible, and data transmission cannot be carried out. Therefore, the gateway server is required to be used as a transfer device for data transfer, so that the public network interphone is accessed to the audio and video conference system provided by the audio and video conference server.
204. The gateway server decodes the voice instruction information.
It can be understood that, after receiving the voice instruction information sent by the audio and video conference server, the gateway server needs to decode the voice instruction information, perform format conversion according to a decoding mode that can be received by the POC server, and transmit the voice information after format conversion. Therefore, the transmitted voice information can be normally received and processed by the POC server, so that the public network interphone system can successfully receive the voice instruction information sent by the audio and video conference access end. It can be understood that the gateway server may also implement interworking between the two types of servers by using other manners, which are not limited specifically.
205. And the gateway server sends the decoded voice instruction information to the POC server.
After the gateway server decodes the voice instruction information according to the format corresponding to the POC server, the decoded voice instruction information needs to be sent to the POC server, so that the intercommunication between the POC system and the SIP system is realized, and finally, the public network interphone can communicate with the audio and video conference access end.
206. And the POC server instructs the public network interphone to play the voice instruction information.
The POC server may manage a plurality of public network interphones. When a plurality of public network interphones initiate a session request, the POC server can provide a communication channel for each target public network interphone, and then simultaneously receive voice information sent by the target public network interphones. Since the POC server uses the packet switching capability of the wireless data network to carry out voice transmission, and is not limited by the geographical position, the long-distance communication of the public network interphone can be realized. The communication distance of the public network interphone is not limited any more, and the communication capacity of the public network interphone is further improved. Meanwhile, the POC server can also send the voice instruction information to all public network interphones connected with the POC server at the same time, so that the public network interphones receive the voice instruction information at the same time, and the simultaneous communication of the public network interphones is realized.
207. And the public network interphone sends the voice information to the POC server.
The audio and video conference access terminal can send voice instruction information to the public network interphone through the forwarding path, and similarly, the public network interphone can also send voice information to the audio and video conference access terminal according to the path so as to realize bidirectional communication. When the public network interphone needs to send voice information to the audio and video conference access end, the POC server can simultaneously obtain the voice information sent by the plurality of public network interphones, then carry out coding processing on the voice information, and then forward the voice information.
208. The POC server forwards the voice message to the gateway server.
After receiving the voice signal sent by the public network interphone, the POC server needs to send the voice information to the gateway server. Similarly, the gateway server, as a transfer station of the audio instruction information, needs to solve the problem of intercommunication between the POC server and the audio/video conference server, and therefore, if the POC server encodes the audio information, the gateway server also needs to decode the audio information, perform format conversion according to a decoding mode that the audio/video conference server can receive, and transmit the format-converted audio information. Therefore, the transmitted voice information can be normally received and processed by the audio and video conference server, so that the audio and video conference successfully receives the voice information sent by the POC server.
209. And the gateway server forwards the voice information to the audio and video conference server.
The gateway server needs to send the decoded voice information to the audio and video conference server, and the audio and video conference server forwards the decoded voice information to the plurality of audio and video conference access terminals.
210. And the audio and video conference server distributes the voice information to a plurality of audio and video conference access terminals.
In the embodiment of the application, the gateway server is used as a transfer station for connecting the POC server with the audio and video conference server, so that the connection between the public network interphone system and the audio and video conference system can be realized, and the gateway server can receive the voice instruction information sent by the audio and video conference access end through the audio and video conference server and transmit the voice instruction information to the POC server. The POC server can also be used for receiving the voice information sent by the public network interphone and transmitting the voice information to the audio and video conference server so that the audio and video conference server can uniformly schedule the public network interphone. The gateway server realizes the intercommunication between the POC server and the audio and video conference server, so that the voice information sent by the public network interphone system can be smoothly accessed into the audio and video conference system through the gateway server. Therefore, the plurality of public network interphones can simultaneously communicate by utilizing the audio and video conference system, so that the communication efficiency and the communication capacity of the public network interphones are improved.
