Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a method for a half-duplex interphone to join an audio and video conference and related equipment.
Background
The half-duplex intercom communicates in a Time Division Multiple Access (TDMA) manner. I.e. the time is divided into periodic frames, each frame is divided into a number of time slots, and the time slots are used for transmitting signals. In one time slot, only one half-duplex interphone is allowed to receive or send voice signals, so that the network end can distinguish the half-duplex interphone by using the time slot and can send voice command signals to the designated half-duplex interphone by using the time slot.
Generally, the communication distance of a half-duplex interphone is limited, and voice signal transmission can be performed only in a short distance range. Moreover, half-duplex interphones within a certain range all utilize the time slot to transmit signals, and one time slot only is exclusive to one half-duplex interphone to normally communicate, so when a plurality of half-duplex interphones communicate, signal interference is easily caused. Therefore, in order to provide the communication efficiency of the half-duplex walkie-talkie, the half-duplex walkie-talkie needs to perform long-distance communication and needs to be scheduled uniformly to avoid interference.
After the half-duplex interphone is added into the audio and video conference system, the problem of long-distance communication of the half-duplex interphone can be solved, and the problem of uniform scheduling of the half-duplex interphone can be realized, so that the problem that how to enable the half-duplex interphone to be smoothly added into the audio and video conference system needs to be solved urgently is solved.

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 half-duplex interphone, a POC server, a gateway server, an audio/video conference server, and a plurality of audio/video conference access terminals.
The half-duplex interphone is connected with the POC server through the first interface gateway. Illustratively, the first 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, and communicates with the half-duplex interphone through the radio frequency unit.
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 second interface gateway.
The following briefly describes each apparatus. The half-duplex interphone may be a Digital Mobile Radio (DMR) interphone device or a Professional Digital Trunking (PDT) interphone device, and is not limited specifically. The half-duplex intercom communicates in a Time Division Multiple Access (TDMA) manner. I.e. the time is divided into periodic frames, each frame is divided into a number of time slots, and the time slots are used for transmitting signals. In one time slot, only one half-duplex interphone is allowed to receive or send voice signals, so that the network end can distinguish the half-duplex interphone by using the time slot and can send voice command signals to the designated half-duplex interphone by using the time slot. In general, half-duplex interphones communicate with each other, which makes their communication limited in distance, and voice signal transmission is generally possible only over a short distance. Moreover, half-duplex interphones within a certain range all utilize the time slot to transmit signals, and one time slot only dedicates one half-duplex interphone to normally communicate, so signal interference is easily caused. Therefore, in order to provide the communication efficiency of the half-duplex walkie-talkie, the half-duplex walkie-talkie needs to perform long-distance communication and needs to be scheduled uniformly to avoid interference.
Based on the above requirements, the half-duplex interphone can be accessed into the audio and video conference system, and the participants (audio and video conference access ends) of the audio and video conference can uniformly schedule the communication process of the half-duplex interphone. Based on the network architecture shown in fig. 1, when the half-duplex interphone sends out a voice signal, the POC server connected to the half-duplex interphone receives the voice signal, and then the POC server sends the voice signal to the gateway server, and then the gateway server forwards the voice signal to the audio and video conference server. Therefore, the half-duplex interphone is accessed to the audio and video conference provided by the audio and video conference server through the POC server and the gateway server and is communicated with the audio and video conference access end. Therefore, the half-duplex interphone can send the voice signal to the audio and video conference access end, and the audio and video conference access end can also output the voice instruction signal (scheduling instruction) to the half-duplex 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 half-duplex interphones connected thereto. When a half-duplex interphone sends a session request, the POC server may allocate a transmission channel (timeslot) for the half-duplex interphone, and then receive a voice signal in a signal corresponding to the half-duplex interphone. For example, the POC client embedded in HyPTTGateway may perform compression coding on the voice signal, and upload the compression coded voice signal 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 signal to each audio/video conference access terminal participating in the conference video, so as to complete transmission of the uplink signal (voice signal). Therefore, each audio and video conference access terminal can send a voice instruction signal based on the voice signal to schedule the half-duplex interphone. After the audio and video conference server receives the voice instruction signal, the audio and video conference server still passes through the path, firstly sends the voice instruction signal to the gateway server, then sends the voice instruction signal to the POC server, and then sends a feedback signal to the half-duplex interphone by the POC server based on the voice instruction signal so as to complete the transmission of the downlink signal (the voice instruction signal). Therefore, the half-duplex interphone can be smoothly connected into an audio and video conference system, and long-distance transmission and unified scheduling of voice signals are realized.
Based on the system architecture, fig. 2 is a schematic flow chart of a method for joining a half-duplex intercom to an audio and video conference, provided by an embodiment of the present application. As shown in fig. 2, the method includes:
201. and the half-duplex interphone sends the voice signal to the POC server.
When the half-duplex interphone is accessed to the audio and video conference, a voice signal needs to be sent to the POC server. For example, the first interface gateway may have a POC client built in. When the POC client receives the voice signal, the POC client may perform compression encoding on the voice signal, and then transmit the compression-encoded voice signal to the POC server.
202. The POC server encodes the speech signal.
It is understood that the POC server may also directly encode the voice signal, and is not limited specifically. The POC server provides a POC system and can manage a plurality of half-duplex interphones. When the target half-duplex interphone initiates a session request, the POC server needs to provide a signal (time slot) for the target half-duplex interphone, and then receive a voice signal sent by the target half-duplex interphone in a designated signal. 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 half-duplex interphone can be realized. The communication distance of the half-duplex interphone is not limited any more, and the communication capacity of the half-duplex interphone is further improved.
203. And the POC server sends the coded voice signal to a gateway server.
After the POC server performs encoding processing on the voice signal, the POC server needs to send the encoded voice signal to the gateway server. The gateway server serves as a transfer station of the voice signal and can transmit the voice signal to the audio and video conference server, and the purpose that the half-duplex interphone is connected to the audio and video conference is achieved. Meanwhile, the POC server can also send the coded voice signals to a POC public network so as to transmit the coded voice signals to other half-duplex interphones, and mutual communication between the half-duplex interphones is realized.
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 half-duplex interphone is accessed to an audio and video conference system provided by the audio and video conference server.
204. The gateway server decodes the voice signal.
Illustratively, after receiving a voice signal sent by a POC server, a gateway server needs to decode the voice signal, perform format conversion according to a decoding mode that can be received by an audio/video conference server, and transmit the voice signal after format conversion. Therefore, the transmitted voice signals can be normally received and processed by the audio and video conference server, so that the audio and video system can successfully receive the voice signals sent by the half-duplex interphone. 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 signal to an audio and video conference server.
After the gateway server decodes the voice signal according to the format corresponding to the audio and video conference server, the decoded voice signal needs to be sent to the audio and video conference server, so that the half-duplex interphone is successfully accessed to the audio and video conference.
206. And the audio and video conference server distributes the voice signal to the audio and video conference access terminal.
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 second 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 signal. The existing audio and video conference provides a communication mode with multiple modes, and comprises that a plurality of audio and video conference access ends can simultaneously send voice signals, only some parties send voice signals, a plurality of people simultaneously receive voice signals, a specific party receives voice signals and the like. Therefore, when the half-duplex interphone is successfully accessed into the audio and video conference server, the audio and video conference access ends can carry out unified scheduling on the communication of the half-duplex interphone, so that the half-duplex interphone can communicate with remote equipment, and the purpose that the communication of the half-duplex interphone is not interfered any more can be realized.
207. And the audio and video conference access end sends a voice instruction signal corresponding to the voice signal to the audio and video conference server.
When the audio and video conference receiving end receives the voice signal sent by the half-duplex interphone, the information carried by the voice signal can be obtained, the audio and video conference access end needs to feed back the information and sends a voice instruction signal to the half-duplex interphone, and therefore the two-way communication between the half-duplex interphone and the audio and video conference access end can be achieved.
The audio and video conference access terminal determines a voice instruction signal according to the received voice signal and needs to send the voice instruction information to the half-duplex interphone. It can be understood that the voice command signal can return to the half-duplex interphone according to the original path to complete the information exchange between the two.
208. And the audio and video conference server forwards the voice instruction signal to the gateway server.
The audio and video conference access end sends a voice instruction signal to the audio and video conference server, then the audio and video conference server sends the voice instruction signal to the gateway server, and the gateway server forwards the voice instruction signal.
209. The gateway server forwards the voice command signal to the POC server.
It can be understood that the gateway server needs to implement the intercommunication between the POC server and the audio and video conference server, and therefore, after receiving the voice instruction signal sent by the audio and video conference server, the gateway server also needs to decode the voice instruction signal first, then perform format conversion according to the decoding mode that the POC server can receive, and then transmit the voice instruction signal after format conversion. Therefore, the transmitted voice instruction signal can be normally received and processed by the POC server, so that the POC system successfully receives the voice instruction signal sent by the audio/video conference access terminal.
210. And the POC server sends a voice feedback signal to the half-duplex interphone according to the voice instruction signal.
And finally, the POC server can send a voice feedback signal to the half-duplex interphone through the radio frequency module on the first interface gateway to complete the whole communication process.
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 server, so that the connection between the half-duplex interphone system and the audio and video conference system can be realized, and the gateway server can receive the voice signal sent by the half-duplex interphone through the POC server and transmit the voice signal to the audio and video server. And the audio and video server can also receive an instruction signal sent by the audio and video conference access end and transmit the instruction signal to the POC server so that the POC server can schedule the half-duplex interphone. The gateway server realizes the intercommunication between the POC server and the audio and video conference server, so that the voice signal sent by the half-duplex interphone system can be smoothly accessed into the audio and video conference system through the gateway server. Therefore, the voice signals sent by the half-duplex interphone can be transmitted in a long distance, the unified dispatching and commanding of the half-duplex interphone can be realized, and the signal transmission efficiency of the half-duplex interphone is improved.
