Today, with the increasingly high development of information technology, more and more enterprises or organizations pay attention to how to improve internal and external work efficiency. However, traditional communication methods such as phone calls, emails, text messages, faxes, etc. cannot meet the efficient and fast requirements of enterprises. Communication requirements, therefore a communication system that can combine various communication methods is needed to meet the daily communication needs of enterprises.
As a product of a new generation of communication technology, converged communications can realize seamless switching of different communication methods and the integration and interconnection of multiple communication systems. In this way, users can make voice calls, video calls, video conferencing, instant messaging, file sending and other communication methods through a unified communications platform. Through the integrated communication system, users can communicate and collaborate anytime and anywhere, making it possible to work conveniently whether in the office, at home or outside.
With the rapid development of communication technology, more and more systems need to be connected to the integrated communication system. In order to build an efficient and unified audio and video integrated communication platform and realize unified integrated command and dispatch functions, what communication systems need to be connected?
Telephone voice system access
The telephone voice system is the basis of the integrated communication system. The integrated communication system can provide E1, loop relay and SIP standard protocols to connect with the operator's PSTN system or the user's local PBX system. Through the SIP standard protocol and various telephone gateways, Realize the interconnection and interoperability of various telephone and voice systems such as telephones, mobile phones, satellite phones, SIP phones, and video phones.
Intercom system access
The wireless intercom system is an important part of the converged communication system. The system includes a converged dispatch platform, DMR/PDT digital intercom system, LTE private network intercom system, 3G/4G/5G public network intercom system, and various wireless intercoms. A complete set of equipment such as terminals realizes the integrated access of existing conventional intercoms, analog/digital intercoms, 3G/4G/5G public network intercoms, and LTE private network intercoms for industry users to achieve cross-system hybrid intercoms and interconnection. and centralized command and dispatch.
The integrated communication system generally connects the wireless intercom system to the command and dispatch system through the intercom gateway. It can not only open up the communication channel between the existing intercom system and other communication systems, but also realize the intercom connection with mobile phones, telephones, dispatch stations, vehicle stations, and mobile phones. stations and other communication terminals for interconnection.
Video surveillance system access
The video surveillance system itself is an independent system. However, due to the improvement of market application requirements, many systems need to use video surveillance resources. In particular, integrated communications, command and dispatch systems, etc. need to interconnect the video surveillance systems.
The integrated communication system can access video surveillance information and supports H.265, H.264, MPEG, MPEG-4 and other video formats. Support video surveillance access (GB28181) and management. For front-end video surveillance systems whose construction era and standards may be inconsistent, multiple access methods can be used for video access. Including DVR/NVR access, monitoring platform access, and surveillance camera access. If the surveillance camera is an analog camera, a network encoder that supports the GB/T28181 protocol needs to be added.
The video surveillance system is connected to the converged communication system to realize the function of viewing surveillance images under the command and dispatch system, and the audio and video business linkage between the surveillance system and other communication terminals; the docking of the video surveillance system with other audio and video communication methods to realize the monitoring terminal and audio Linkage scheduling of video communication terminals.
Video conferencing system access
Video conferencing system, also called video consultation system, is an important system for multiple people to participate in meetings collaboratively. There are two ways for the video consultation system to connect to the converged communication system:
1. Connect with MCU through standard SIP protocol
After the system is connected to the video conferencing system MCU through the standard SIP protocol, the MCU initiates the video conference and the command and dispatch system initiates the meeting. The MCU dials the dispatch center number of the command and dispatch system or the command and dispatch system dials the venue number of the video conferencing system to connect the two venues.

2. Connect to the video conferencing terminal in a back-to-back manner
If the video conferencing system does not support standard protocols, the system can use a video conferencing Internet gateway to connect to the video conferencing terminal under the video conferencing system.
The video conferencing system is connected to the command and dispatch system to realize multi-party video conferencing business linkage and realize cross-platform collaboration and dispatching interoperability for conference discussions.
Broadcast system access
The broadcast system is an important audio system and is widely used in many fields. In actual application scenarios, the broadcast system is divided into analog broadcast system and IP broadcast system. The integrated communication system can provide corresponding access methods according to specific situations.
1. Analog broadcast access
If the distance between the integrated communication system and the broadcast equipment is too far, you can use a remote broadcast access gateway to access the integrated communication system through the IP network/internal private network. Broadcast notifications to the broadcast terminals can be achieved through the integrated communication system. .
2.IP broadcast access
When the IP broadcasting system supports the standard SIP protocol, the converged communication system and the IP broadcasting system can be connected through SIP trunking. After the IP broadcasting system is connected, point-to-point and grouped area broadcasting for terminals in the IP broadcasting system can be realized through the converged communication system. notify.
The broadcast system is connected to the converged communication system to realize the integration and interoperability of the broadcast system and other communication systems. Group broadcast is realized through the dispatch station, IP phones, and intelligent terminals, so that the broadcast notification has real-time, timing and other rich functions.
As an open system platform, the converged communication system can integrate and access a variety of communication systems and devices, and achieve interconnection and interoperability through specific communication protocols and technologies. In the future, with the continuous development of communication technology and the continuous improvement of application requirements, the converged communication system will also integrate richer protocols. We will continue to promote the further integration and development of communication systems and industry business systems to realize a new generation of command information platform (communication +Business+Big Data+Artificial Intelligence)
