Description

The invention relates to communication technology and is intended for organizing an automated connection of mobile subscriber stations.

A device is known (patent No. JP2003143294, publ. May 16, 2003), including a control unit connected via a control bus to a signal input / output unit, which is used to connect to a terminal device, a signal processing unit that performs signal processing and measures the quality of communication, input unit signal output base station, which serves to transmit a signal to the base station. The signal input / output unit of the base station is connected by a data bus to the signal processing unit and the signal input / output unit. This device has a modular structure and allows, if necessary, to increase the number of structural blocks depending on the number of base stations and terminal devices.

This device does not realize the ability to receive / transmit information through the joints of C1FL-BI, TCh, BCC. The operating mode on channel E1 is not implemented. It is not possible to keep the subscriber of a subscriber radio station communicating with a switching equipment subscriber when a subscriber radio station moves from the service area of one base station to the service area of another base station.

A known controller (patent US5809018, publ. 09/15/1998), adopted as a prototype, including a control unit for controlling the switching unit and base radios, an interface unit for transmitting calls and signaling messages to base radios and from base radios to the controller, switching unit and memory unit . The interface unit is connected to the switching unit via a bus for transmitting voice information and a bus for transmitting alarm messages. The switching unit is additionally connected via the bus to the control unit, which is connected via the bus to the memory cell.

The prototype does not realize the ability to receive / transmit information through the joints of C1-FL-BI, PM, BCC. The mode of operation on the E1 channels is not implemented. It is not possible to keep the subscriber of a subscriber radio station communicating with a switching equipment subscriber when a subscriber radio station moves from the service area of one base station to the service area of another base station.

The technical result of the invention is to expand the functionality of the device, expressed by providing operating modes for receiving / transmitting channels at the joints of C1-FLBI, TCH, BCC, as well as the operating mode on E1 channels, by realizing the ability to keep the subscriber of a subscriber radio station communicating with a subscriber of switching equipment during the transition radio stations from the service area of one base station to the service area of another base station.

The specified technical result is achieved by the fact that the network controller (hereinafter referred to as the controller) consists of addresses / data of the control unit bilaterally interconnected via the bus, the first interface unit with the BCC interface, the second interface unit with the C1-FL-BI interface, the first channel termination cell with joints С1-ФЛ-БИ and ТЧ, second cell of channel terminations with joints for providing reception / transmission of information via Е1 channel, Ethernet interface and RS-232 interface, service communication cell. In this case, the control unit is bilaterally connected with an additionally entered display cell.

The invention is illustrated in the figure, which shows the structural diagram of the controller.

The controller consists of the first block of interface 1 with the joints of the BCC, the second block of interface 2 with the joints of C1-FL-BI, the first cell of channel terminations (UAC) 3 with the joints of C1-FL-BI and TCH, the second cell of channel terminations (UAC) 4 with the joints E1, Ethernet, RS-232, intercom cell (JAC) 5, control unit (CU) 6, address / data bus 7, display cell (IIN) 8 associated with CU 6, two power supplies 9, 10. First interface unit 1, second interface unit 2, the first YAKO 3, the second YAKO 4, YSS 5 and BU 6 are bilaterally connected via the address / data bus 7.

The first block of interface 1 provides the interface of the controller with the base radio station (BR) via one information-control channel with the junction of the BCC.

The second block of interface 2 provides the interface of the controller with the BR from one to four information channels at the joints of C1-FL-BI and one control channel at the interface of C1-FL-BI.

The first YAKO 3 provides the interface of the controller with the switching equipment (ATS) from one to four information channels at the joints of C1-FL-BI and from one to four control channels at the joints of the PM.

The second YAKO 4 provides the interface of the controller with the exchange to twenty-eight information channels E1 and one control channel E1. In the second YAKO 4, a PC connection is used through the connection connector to provide reception / transmission via the RS-232 interface for outputting service information, and organization of device combining through the connection connector to provide reception / transmission via the Ethernet interface is also carried out.

JSS 5 provides official communication between the controller operator and the BR through the information control channel with the joint of the bcc of the first block of interface 1.

БУ 6 manages the communication of subscribers of subscriber radio stations (AR) with access to the PBX channels, monitoring the status of the equipment of the controller and the BR, exchanging control and control signals between the controller and the PBX, the controller and the BR, non-volatile storage of information about the configuration of the communication network.

JIN 8 provides input from the front panel of control commands and an indication of the control and monitoring of the controller.

BP 9, 10 provide the conversion of the primary voltage of 220 V into stabilized supply voltages of the cells and controller units, as well as the possibility of hot power backup.

The controller has a modular structure, which allows you to change its configuration depending on the number of BR connected with the controller and allocated communication channels (BCC or C1-FL-BI) between the controller and the BR. Accordingly, the number of installed cells and interface units in the controller changes, namely, the number of the first UCO 3 is determined by the number of channels in the exchange; the number of the first blocks of interface 1 corresponds to the number of BR with channels with a junction of the bcc; the number of second blocks of interface 2 corresponds to the number of BRs with channels with an interface C1-FL-BI.

The controller operates as follows. After turning on the power from the PBX, the first YAKO 3 controller receives the marker signal in the form of a tonal frequency via the PM channels, indicating the corresponding information channel free of connections. The marker signal of each of the four information channels is fixed in the first YAKO 3, converted into a digital code and, through a common address / data bus 7, goes to the control unit 6, which is combined with the rest of the BR and AR control information into TU-TS information. Information TU-TS through a common bus address / data 7 is fed to the first block of interface 1 and the second block of interface 2. Through the control channel at the junction of the BCC of the first block of interface 1 and the control channel at the junction of C1-FL-BI of the second block of interface 2, the information is received BR as a sign of an information channel free of communication with AR.

The control commands for turning on and off the channel connections, controller, BR and AR operating modes are entered by the operator from the front panel of YaIn 8 or from the PC at the RS-232 interface of the control unit 6. The control commands are transmitted to the control unit microcontroller 6, where they are processed and combined into the control information -TS and are transmitted via the address / data bus 7 to the first block of interface 1 and the second block of interface 2 from where they arrive at the BR and AR.

An incoming call from the telephone exchange through the channel with the junction of the PM and the signal through the information channel at the junction of the C1-FL-BI arrive at the first YAKO 3. The signal through the information channel is converted to logical levels, processed and digitally fed to the common address / data bus 7 for transmission to the first block of the interface 1, the second block of the interface 2. The call signal is converted into a digital signal and is included in one of the bytes of information TU-TC of the first block of the interface 1, the second block of the interface 2 for transmission to all BRs with free and working information channels.

An incoming call from the PBX to the YAKO 4 through the control channel E1 is included in one of the bytes of information of the TU-TS of the first block of interface 1, the second block of interface 2 for transmission to all BRs with free and serviceable information channels, and the signal through the information channel E1 in digital the code enters through the address / data bus 7 to the first block of interface 1, the second block of interface 2.

When receiving signals from the microphone (MT) in JSS 5, the analog speech signal is converted into a digital signal for transmission via a common address / data bus 7 to the first interface unit 1 and further to the BR. The signal arriving from the BR through the first block of the interface 1 via the address / data bus 7 is sent to JSS 5, where it is converted from a digital signal into an analog speech signal and transmitted to MT.

In the first block of interface 1, channel information is formed with the junction of the BCC, including data from the first UKO 3 via information channels of communication with the PBX, or data from the second UKO 4 through information channels from the PBX, information from the communication channel from YSS 5 and TU-TS from BU 6. Through the information-control channel with the junction of the BCC, information flows to the BR and then to the subscriber in the AR.

In the second block of interface 2, channels with C1-FL-BI joints are formed according to data from the first Yako 3 or according to data from the second Yako 4 and a TU-TS channel from BU 6 with a C1-FL-BI junction. Through the information channel with the junction of C1-FL-BI and the control channel with the junction of C1-FL-BI, information is transmitted to the BR and then to the subscriber in the AR.

After processing the call signal in the AR, a response signal is generated, which is transmitted to the BR and from the BR controller. The TU-TS channel information receives a counter call with the number and data on the state of the AP equipment, as well as the wave number of the BR receiver that received the AP response. Control unit 6 of the controller gives the command to turn on the channel connection at the junction of C1-FL-BI of the first YAKO 3 or channel E1 of the second YAKO 4 with the information channel of the first block of interface 1 (second block of interface 2) of the BR, which has better signal quality, sends it to AR through the BR, the numbers of the transmitter and receiver waves, the command to connect the ATS information channel to the AR, removes the call signal of the AR for the remaining BRs. This connection is held in the controller until the end signals from the PBX or AR are received, or until the AR connection switches to another BR when the AR moves to the service area of the new BR.

An incoming call from the BR is fixed on the TU-TS channel to one of the interface units 1, 2, where the conversion of input analog signals to digital form is performed. The controller BU 6 gives a command to turn on the channel connection at the junction C1-FL-BI of the first YAKO 3 or channel E1 of the second YAKO 4 with the information channel of the first interface unit 1 (second interface unit 2). The signals from the microcontroller BU 6 in JIN 8 indicate the control commands, the status of the blocks and cells of the controller, the presence of subscriber connections, the presence of communication between the controller and the base radio stations, receiving and transmitting calls.

The communication channel of the AP with the PBX channel is kept (in the first YAKO 3 or in the second YAKO 4) when the AR moves from the service area of one BR to the service area of another BR automatically according to the program installed in the controller. The controller issues commands through one BR to the AP to switch the frequencies of the transmitter and receiver of the AP for radio communication with another BR, switches the PBX connection from one BR (first interface unit 1 or second interface unit 2) to the corresponding information channel of the other BR (first interface unit 1 or the second block of the interface 2), while maintaining the same PBX channel with the controller. In a PBX, the connection channel with the speech-forming device does not change. Therefore, the conversation between the AP subscriber and the PBX subscriber is saved even with a short-term disconnection.

The connection is disconnected in the controller at the initiative of the AR by the signal “End” from the side of the AR, which is received via the TU-TS channel from the BR. When the connection hangs up at the initiative of the operator, the controller, by the signal of the marker with the PBX, disconnects the channel connection with the BR and transmits the “End” signal to the BR. The record of the modes and parameters of pairing with the PBX and BR is recorded in the non-volatile memory of the controller 6.
