Description

The utility model relates to the field of mobile communications, and can be used to provide emergency services to mobile subscribers. The system involves equipping an individual (subscriber), a moving object or a real estate object with a subscriber terminal, as well as registering a subscriber (object) in the system database. The service provider is a service provider that interacts with the communications system operator and the emergency service.

Considering the urgency of the problem of ensuring public safety and international experience in providing emergency operational services, the Government of the Russian Federation adopted Decree No. 894 of December 31, 2004 “On approval of the List of emergency operational services, the call of which is required to provide a communication operator with a communication user around the clock, and on the appointment of a single emergency call number. " The single call number for these services is the number "112".

Unified emergency services, called by a single number, operate in most economically developed countries. There is a decision of the international association of GSM communication system operators to provide a free connection by the number "112" even with a locked phone and without a SIM card.

In Russia, the system for providing emergency call services through a single number "112" (the official abbreviation is System-112) is being built on the basis of unified duty dispatch services (EDDS) of municipalities.

By order of the Government of the Russian Federation of August 25, 2008 No. 1240-r, the Concept of creating a system for providing emergency call services via a single number 112 was approved on the basis of unified duty dispatch services of municipalities.

The basis of the technological construction of the system-112 is made up of standard unified software and technology complexes (UPTK) and corresponding networks, facilities and communication facilities. UPTK implements the functions of several subsystems, including a subsystem for receiving and processing calls, designed to receive and process calls (incident messages) received in the UDDS from the emergency call centers belonging to the telecom operator and transfer them to the corresponding duty dispatch service. The structure of the indicated subsystem includes a call processing center (incident messages), where calls are received and processed, received in a single duty dispatch service by the number "112".

The existing technology for calling emergency services consists in organizing a voice connection with a local emergency operator. In the dialogue, the operator is informed of the reason for the appeal, by which he makes an adequate decision on the prompt response. Due to the emergency nature of the call, situations arise when the caller does not have time to communicate all the information necessary for taking action. For this, equipment is used to automatically determine the number of the caller, by which the service operator can make a call back. However, if the call comes from a mobile phone and for some reason feedback from the subscriber cannot be established, or the subscriber finds it difficult to name his place of residence, the only way to provide timely assistance to the caller is to automatically determine his location. At the same time, the existing technologies for determining the location of subscribers by means of the network (Cell-ID) of the Russian mobile (cellular) operators provide unacceptably high positioning errors (from hundreds of meters to units of kilometers, depending on the density of the base stations).

A device for calling emergency assistance, operational communications and the supply of a hidden radio signal, comprising a talking unit, including a telephone and a microphone, an SMS message transmitter including a keyboard and a screen, and an autonomous power source (patent RU No. 2277264, class G08B 25/10, publ. 01/27/2006).

The conversation unit is made with two emergency call buttons (first and second buttons), and the device is equipped with two remote emergency call buttons (third and fourth buttons), the first button being programmed to call the information-operator point, the second button to automatically dial the number of one of telephones, for example, a single duty dispatch service of the Ministry of Emergencies, the third button - to dial, for example, a single duty dispatch service with the automatic transmission of a pre-dialed SMS message, and a fourth button - to place the device in a security standby mode.

The text of the SMS message is formed in advance by the subscriber using keys having the alphabet and numeric values, and stored in the device’s memory.

However, the known device has insufficient functionality, in particular, there are no built-in means of accurate positioning (for example, based on satellite navigation systems) and, as a result, there is no possibility of transmitting location data to the operator's station or to the emergency service.

A known alarm system and location, designed to promptly notify interested parties and specialized services of emerging security threats to subscribers (patent RU No. 2259595, G08B 25/12, publ. 27.08.2005). The system contains a subscriber unit, which includes a mobile (GSM) phone with a connected Bluetooth wireless module. The telephone provides two-way data exchange via a standard communication and data transmission network with the provider's equipment connected with the dispatch center. The subscriber has a hidden alarm button and a GPS module, each with its own Bluetooth module, which can exchange data with the Bluetooth module of a mobile phone. Using this set of technical means, the subscriber can in an emergency situation covertly transmit alarm notifications and location data without removing the GSM phone from the pocket of his clothes or bag, which is ensured by the use of wireless communication between the GSM phone, GPS module and the panic button. The dispatch center is made with the possibility of interaction with the forces and means of response.

The disadvantage of the considered system is the impossibility of sending to the dispatch center a message about the location of the subscriber in the absence or blocking of the SIM card (since standard data services in the GSM network are used), which significantly reduces the reliability of the system.

At the same time, there is an urgent need to provide an emergency call rather quickly and with high reliability of data transmission using a subscriber device of a public mobile communication system.

By technical nature, taking into account the peculiarities of building a Russian emergency call system based on a single number "112" (System-112), the closest to the proposed technical solution is a public safety telecommunication system containing a monitoring center connected via a communication network to subscriber terminals, each of which contains a transceiver, a receiver of a satellite-based positioning system associated with it, allowing to calculate geographic coordinates, and a means for sending messages, due to which the transmission to the monitoring center (by the telephone number of this center or the address in the communication network previously recorded in the transceiver) of messages containing the unique number of the subscriber terminal, its coordinates, as well as a limited number of messages (RF patent No. 51433, Cl. G08B 25 / 00 dated 2006.02.10).

The monitoring center is designed to receive voice, alphanumeric and multimedia messages from subscriber terminals, and voice messages can be transmitted via GPRS channels of the GSM network. The subscriber terminal provides the connection of sensors for remote monitoring of the parameters of the object on which the terminal is installed, and control devices for remote exposure to the object.

The disadvantage of the system considered is the lack of a mode for transmitting digital messages via voice channels of used communication networks, while emergency call systems based on a single number "112" (System-112), as well as on the basis of existing separate telephone numbers of operational services (01, 02 , 03, 04), designed to receive calls on standard voice channels. In addition, this system does not provide for emergency services to receive personal data of callers (passport, medical data, contacts of loved ones, etc.), which may complicate the prompt adoption of adequate assistance measures.

In terms of technical nature, the closest to the proposed second technical solution is a subscriber terminal for a telecommunication public safety system, containing a transceiver of a communication network, for example, GSM, in which the address of the dispatch and monitoring center in the communication network, a personal subscriber number and a limited number of messages, for example, associated with poor health, threat of attack, etc., and the transmission of each message is provided by pressing the appropriate button means posa ki messages via the transceiver, as location of the subscriber terminal positioning accuracy determined communication network (RF Patent PM №51433, Cl. G08B 25/00 on 2006.02.10).

However, the known subscriber terminal does not provide the ability to transmit data about the location of the subscriber via the voice channel of the mobile communication system in the absence or blocking of the subscriber identity module (SIM card).

The technical result of the first technical solution is the creation of a system for providing emergency services to mobile subscribers, which increases the efficiency of emergency calls from mobile subscribers to UTDS, by providing the necessary information about the subscriber, the nature and location of the incident, and the possibility of making a call from the subscriber terminal without SIM cards, or with a locked SIM card.

The technical result of the second technical solution is the development of a subscriber terminal for providing emergency services to mobile subscribers with the ability to make an emergency call, including a voice call, at the command of a subscriber, or automatically by the state of the sensors, including when there is no SIM card.

The delivered technical results are achieved by the fact that the system for providing emergency services to mobile subscribers contains a monitoring center, including a database and interconnected for the exchange of information by the first input-output with the first input-output of a unified software and technology complex of a single duty dispatch service providing reception emergency calls through a single number "112", and the complex is interconnected for voice messaging by the second input-output through the network movably communication with subscriber terminals, and the monitoring center is interconnected by the second input-output through the mobile network with subscriber terminals, each of which has an identification number and is configured to determine the coordinates of its location and transmit them together with the identification number to the monitoring center, as well as initialization voice connection with the complex with simultaneous transmission of coordinates and identification number, as well as an additional linear modem, connected between the center input nitrating and the second input-output of a unified software and technology complex for extracting from the received signal the coordinates of the location and identification number of the subscriber terminal, in addition, the subscriber terminal is configured to determine the coordinates of its location, transmit them together with the identification number to the monitoring center, as well as initialize voice connection with a unified software and technology complex with simultaneous transmission of coordinates and identification numbers, while it contains a power supply unit, a transceiver of a mobile communication system with an antenna connected to a low-frequency modem interconnected with a controller, to which a device for calculating location, call buttons and a storage device having at least a subscriber terminal identification number and a telephone or IP number are connected address of the monitoring center. In addition, the subscriber terminal further comprises a telephone, a microphone and / or integrated sensors and / or an interface unit with external sensors connected to the inputs.

The essence of technical solutions lies in the fact that the implementation of the proposed system and its subscriber terminal in the manner described above allows us to achieve the set technical results.

Comparison of the proposed technical solutions with the closest analogues allows us to assert that they meet the criterion of "novelty."

Preliminary tests allow us to judge compliance with the criterion of "industrial applicability".

Figure 1 presents a block diagram of the proposed system and its subscriber terminal.

The system for providing emergency services to mobile subscribers contains a monitoring center 1, including a database 2 and interconnected for the exchange of information by the first input-output with the first input-output of the unified software and technology complex 3 (UPTK) EDDS, providing emergency calls through a single number "112."

Complex 3 is interconnected for voice messaging by the second input-output through the mobile communication network 4 with subscriber terminals 5-1 ... 5-N, and the monitoring center 1 is interconnected by the second input-output through the mobile communication network 4 with subscriber terminals 5-1 ... 5- N, each of which has an identification number and is configured to determine the coordinates of its location and transmit them together with the identification number to the monitoring center 1, as well as to initialize a voice connection with complex 3 while transmitting ordinates and an identification number.

Monitoring center 1 is a software and hardware complex that includes a server part (database 2, telecommunication server, etc.) and may additionally contain automated workstations (AWPs) of operators based on personal computers.

The first input-output of complex 3 is a standard data transmission interface for information interaction with a telecom operator, or a specially organized interface for connecting a service provider (via a dedicated line, via an Internet connection, etc.), or e-mail of the 112 service.

The second input-output of complex 3 is a regular voice interface that is connected to the emergency call center, belonging to the mobile operator, for exchanging voice messages with mobile subscribers through the mobile network 4.

The subscriber terminal 5-i contains a power supply unit 12, a transceiver 6 of a mobile communication system with an antenna 7 connected to a low-frequency modem 8. The modem 8 is interconnected with a controller 9, which ensures the operation of the subscriber terminal and, in particular, the generation of digital messages converted by the modem 8 into Line signals for voice channel transmission.

Modem 8 can be implemented on an FX469 chip manufactured by CML Microcircuits, Inc (USA), which provides data transmission in the frequency band of the telephone conversation path at a speed of 1200/2400 baud with FFSK modulation (fast frequency shift key - fast frequency-hopping modulation).

The controller 9 can be performed on a single-chip microcontroller, for example, on a chip 8-bit microcontroller ATmega 1280 company Atmel (USA).

A memory device 10 is connected to the controller 9, in which at least the identification number of the subscriber terminal 5-i and the phone number or IP address of the monitoring center 1 are stored. In addition, the storage device 10 can store various parameters of the operating conditions of the subscriber terminal, and also perform the functions of a “black box”, i.e. record location data, sensor triggers, etc. An example of the implementation of the storage device 10 is a non-volatile (based on Flash technology) microcircuit AT45DB011D manufactured by Atmel (USA).

The controller 9 is also associated with the device 11 for calculating the location and buttons 13-1 ... 13-k call.

The main embodiment of the device 11 is a built-in navigation receiver with an antenna (not shown in FIG. 1), which calculates the geographical coordinates of the location using signals from satellite navigation systems (Glonass, GPS, etc.). An example of an embedded navigation receiver that supports the processing of signals from two systems - GLONASS and GPS, is the MNP-M5 module manufactured by Izhevsk Radio Plant OJSC.

It is also possible to implement the device 11 on the basis of other known methods of positioning (positioning), for example, according to the signals of a cellular communication system or a wireless communication system (Wi-Fi, DECT, etc.), or based on inertial navigation.

An example of the use of wireless communication systems (Wi-Fi) in the tasks of positioning subscribers is the Wi-Fi Positioning System (WPS) of Skyhook Wireless (USA). The main feature of this system is that when determining the coordinates of the object, wireless Wi-Fi access points are used. Any subscriber who has a device with a Wi-Fi controller (laptop, PDA, smartphone, communicator, etc.) who needs to install special software can use the system’s services.

An example of the implementation of device 11 based on inertial navigation is the compact integrated inertial navigation system KompaNav-2T developed by the Russian company TeKnol based on the integration of microelectromechanical sensors (MEMS) and a satellite navigation system receiver (GLONASS, GPS).

Call buttons 13-1 ... 13-k are intended for the subscriber to send a command to transmit to a specific recipient the corresponding message. For example, when one button is pressed, an SMS message can be generated to the monitoring center 1, and when another button is pressed, a voice call to the standby operator of the EDDS will be made.

The subscriber terminal 5-i may further comprise a telephone 14 and a microphone 15 and / or integrated sensors 16 and / or an interface unit 17 for interfacing with external sensors.

Built-in sensors 16 are a set of various sensors that are structurally included in the subscriber terminal, and provide the ability to monitor the status of the subscriber (object) equipped with the subscriber terminal, as well as the automatic generation and transmission of emergency messages when an emergency is detected. For example, the built-in sensors may include an accelerometer, due to which, based on the measurement of the resulting accelerations, the accident state of the vehicle on which the subscriber terminal is installed can be automatically identified. Currently, a large number of various sensors are produced in the world in miniature design, including in the form of microcircuits. An example of a single-chip triaxial accelerometer is the ADXL330 chip manufactured by Analog Devices (USA).

The node 17 interface with external sensors provides the connection to the subscriber terminal of additional external sensors 18-1 ... 18m, allowing to expand the functionality of the subscriber terminal.

The number of call buttons 13-1 ... 13-k, the composition of the built-in sensors 16, the number of inputs 18-1 ... 18-m for connecting external sensors, as well as technical options for the device 11 and node 17 are determined by the specific implementation of the subscriber terminal.

In addition, a linear modem 19 is additionally introduced into the system, connected between the input of the monitoring center 1 and the second input-output of complex 3.

The modem 19 provides the selection of digital data (location coordinates and identification number of the subscriber terminal) from the signal transmitted by the subscriber terminal 5-i during the initialization of a voice connection with the emergency service (EDDS), and the transmission of these data to the monitoring center 1. Modem 19 is a device containing a power supply and a controller that is interconnected with a low-frequency modem similar to that used in the 5-i subscriber terminal, the linear input-output of which is designed to connect to the emergency call center that belongs to the mobile operator. The controller provides a data interface with the monitoring center 1.

The principle of operation of the proposed technical solutions is as follows.

If the subscriber presses the call button 13-i on the subscriber terminal 5-i, or if an emergency condition is detected by one or more built-in sensors 16, or one or more external sensors connected to inputs 18-1 ... 18m, an event is recorded by the controller 9.

There are two options for handling the event.

Option “1”: Subscriber terminal 5-i determines the coordinates of its location, generates a digital data packet containing at least the terminal identification number and location coordinates, and transmits this information to monitoring center 1 via standard data transmission channels (SMS, CSD, GPRS, USSD) mobile communications systems. At the same time, the subscriber terminal initiates a voice call by a single emergency call number “112” to establish voice communication between the subscriber and the emergency operator on duty (EDDS).

Monitoring center 1, which received a digital data packet from subscriber terminal 5-i, searches the database 2 for information about the subscriber (object) using the terminal identification number and, if the search result is positive, selects available information from the database for this subscriber (object), after which transmits this information, as well as the location coordinates received from the subscriber terminal 5-i, to the complex 3 of the EDDS. Thus, during a conversation between the duty operator of the EDDS and the subscriber, complex 3 from the monitoring center 1 will automatically receive information about the scene of the incident and data about the subscriber (car, real estate).

The implementation of option "1" implies the presence in the subscriber terminal of the subscriber identity module (SIM card).

Option “2”: The subscriber terminal 5-i determines the coordinates of its location, makes a voice call via the mobile communication network 4 by the telephone number “112” and, when establishing a voice connection, forms a digital data packet using at least an identification modem 8 containing at least an identification data terminal number and location coordinates, which is transmitted “over the voice”. A linear modem 19 is connected to the monitoring center 1, which is connected to the telephone line of complex 3 and ensures the isolation of a digital data packet from the mixed signal (voice + data) generated by the subscriber terminal 5-i. The extracted data is processed in the monitoring center 1, as a result of which the initial information generated by the subscriber terminal 5-i is restored. In accordance with the identification number received from the subscriber terminal 5-i, the monitoring center 1 searches the database 2 for information about the subscriber (object) and, if the search result is positive, selects the available information from the database 2, then transmits this information, as well as the coordinates of the place incidents in emergency service.

If option 2 is executed, the SIM card may be missing.

The choice of this or that scenario is carried out when programming the operating modes of the subscriber terminal 5-i (and writing them to the storage device 10).

Thus, the proposed technical solutions achieve the set technical result.
