Description

The invention relates to the field of automation and communication, in particular, to systems of technological, operational-technological, dispatch and telephone communications.

The integrated digital technological communication system ICTS is known, which is a technological communication system built on an IP platform (Internet page http://pulsar-telecom.ru/ru/publication/content/702.htm). Elements of the ITSTS system:

Call Processing Server (SOB) • - the main control element of the system, which processes signal messages from media gateways, provides the organization of telephone conversations between subscribers and controls the operation of the main services provided by the NSR server.

Media Application Server (SMP) • - is the main element of the system that provides the ability to provide registration of negotiations, collect data for charging calls, additional types of telephone communications, and also provides the function of voice auto-informer.

The ММШ-044 modular media gateway • - is designed to organize the interface of voice services in an IP network; Provides data stream conversion between circuit switching and packet switching networks.

The universal module repeater RMU-4 • - is designed to organize train radio communications in analog mode in the HF band (2 MHz), in analog mode in the VHF band, in digital mode according to the DMR standard in the VHF band (160 MHz).

• Network IP-cameras and video terminals - designed to solve the problems of video communications and video surveillance.

The amplifier modular combined UMK-4 • - is designed to connect the feeders of the broadcast network, measuring microphones, park intercoms, information displays, emergency communication columns of the CISSOP subsystem.

• KSSU crates - designed to expand the distributed combined IP PBX to remove subscriber capacity or connect E1 streams to a remote site.

A disadvantage of the known system is the obligatory availability of a call processing server (SOC) and a media application server (SMP) that switch calls and voice traffic of the entire ICTS (from all subscriber devices), which leads to a significant decrease in the reliability and survivability of the ICTS. The installation of SOV and NSR at each station leads to the need to ensure the conditions for their work and the installation of equipment that ensures the operation, which leads to an increase in the cost of ICTC and the complexity of operating the system due to a larger number of devices.

The principle of operation of the KAU 1 network is to establish a connection between two or more KAU 1 and / or systems integrated with it (for example, 12-19 in FIG. 1) without the participation of a central switch server or switching server.

The principle of operation of KAU 1: on each of KAU 1, information on subscribers and services (services) and addresses / names of KAU 1, as well as information on systems integrated with them, to which KAU 1 can initiate and / or accept individual or group voice and / or video calls and / or other services prescribed in the KAU 1 database and corresponding to the program modules 6 in KAU 1. The databases of all KAU 1 and server 7 of the monitoring and control system are automatically maintained in an up-to-date state, and with If necessary, the update is carried out according to the criteria defined in the settings on server 7 of the monitoring and control system.

Call organization principle: a subscriber, using KAU 1, makes individual or group, or broadcast voice, or video calls of one or several subscribers with KAU 1 by pressing the corresponding button on the screen form of the KAU 1 touch screen. All participants of KAU 1 call upon receiving signal information from call initiator KAU 1 begin the exchange of signaling information, after which the connection is established and the exchange of media traffic begins. Signal information, voice or video traffic is transmitted over the network 2 data transmission based on IP.

If the subscriber, using KAU 1, makes calls to the systems 12-19 integrated with KAU 1 by pressing the corresponding button on the screen form of the touch screen KAU 1, then KAU 1 exchanges signaling information with the corresponding system with which it has integration , after which the connection is established and the transmission of voice traffic in simplex or half-duplex, or full duplex mode begins, in case of a call to the station of general technological telephone communication 18. Signal information, voice traffic are transmitted over the network data transmission based on IP 2. If the system with which KAU 1 is integrated does not have a connection to a data transmission network based on IP 2, calls are established through gateway 11 via the following interfaces: analogue PM (tone frequency) ports, RS-232 , RS-485, ISDN PRI, ISDN BRI, E1.

Thus, the use of the invention allows to increase the efficiency of the use of computing resources of the system equipment, to abandon the use of switching stations, servers and software switches through the use of switching subscriber devices, networked according to the principles of a neural network and using a distributed VoIP platform.
