The utility model relates to telecommunication devices, namely to mobile communication terminals (cell phones) that can be used in the telemetry services of the network operators of the Global System for Mobil Communication GSM networks, mainly in telemetry devices for monitoring mobile objects (software) to determine the status of major software systems and software locations.

A known terminal comprising a processor, a transceiver, a first antenna, a modem, a global positioning system receiver, a second antenna, an input / output port, wherein the transceiver is connected by its first input-output to the first antenna and the second input-output to the first input-output modem, the second input-output of the modem is connected to the first input-output of the processor, the second input-output of the processor is connected to the input-output of the input-output port, the receiver of the global positioning system is connected to the first input-output ohm with a second antenna, and the second input-output - with the third input-output of the processor (US 6334061, publ. 2001).

In this design, a burglar alarm unit is additionally connected to the terminal (mobile phone) via the input / output port, which allows using the global positioning system (GPS) to perform the following functions individually or in some combinations:

Determine software locations

A limitation of this design is the complexity of connecting the alarm block through the input / output port, which is associated with the need to temporarily coordinate the transmission of impulse signals from an external device and coordinate the time of their arrival with the processor directly for normal operation (without failures) of this device, since the processor at the same time (at the time of the alarm), it can perform its main functions when the terminal is operating directly in communication with the terminal Emperor of the GSM. The main drawback of the design is the low processing efficiency of incoming signals. In addition, attempts to combine individual functional devices in order to expand the capabilities of the system inevitably lead to a deterioration in the weight and size and cost characteristics of the equipment set.

The closest design is a known mobile communication terminal, comprising a processor, a transceiver, a first antenna, a modem, a global positioning system receiver, a second antenna, an input / output port, wherein the transceiver is connected by its first input / output to the first antenna and the second input to output - with the first input-output of the modem, the second input-output of the modem is connected to the first input-output of the processor, the second input-output of the processor is connected to the input-output of the input-output port, global system receiver s location is connected by the first input-output to the second antenna, and the second input-output to the third input ohm-output ohm processor (RF Patent for utility model No. 31183, Н 04 В 1/38, publ. 2003).

In addition, this design contains a microcontroller that is connected to the second input-output of the processor and the input-output of the input-output port; therefore, the processor is connected to the input-output of the input-output port not directly, but through a microcontroller that connects peripheral equipment or communication channels to the central the processor. In this design, to ensure the operation of the modem, it is necessary to use an additional connection of the input-output port with the third input-output of the modem, which additionally complicates the device and reduces its performance.

The figure depicts a functional diagram of the claimed utility model.

The mobile communication terminal (Fig.) Contains a processor 1, a transceiver 2, a first antenna 3, a modem 4, a global positioning system (GPS) receiver 5, a second antenna 6, and an input / output port 7. The transceiver 2 is connected by its first input-output to the first antenna 3, and the second input-output to the first input-output of the modem 4. The second input-output of the modem 4 is connected to the first input-output of the processor 1. The second input-output of the processor 1 is connected to port 7 input-output. GPS receiver 5 is connected to the second antenna 6 by the first input-output and the second input-output to the third input-output of the processor 1. A switch 8 for exchanging data of external digital devices is introduced. The switch 8 is connected to the fourth input-output of the processor 1 by the first input-output. The second input-output of the switch 8 is connected to the input-output of port 7 and is designed to connect an external digital device, for example, a digital alarm unit. The processor 1, transceiver 2, modem 4, GPS receiver 5, port 7 and switch 8 are located in a single package (the figure shows a dashed line by a dash line).

A software alarm block can be used as an external digital device, which can be connected through the corresponding connector of the input-output port 4 in the usual way, and a car can be used as software (not shown in Fig.).

A message from the base station 9 of the GSM operator arrives at the first antenna 3 of the transceiver 2 and through the modem 4 to the first input-output of the processor 1. The processor 1 controls the operation of logical, arithmetic and other operations of internal and external devices without the use of a microcontroller. When an alarm signal is received from the security alarm unit (not shown in Fig.), Connected in the usual way to port 7, for example, when a car is opened, a digital alarm signal is sent to switch 8. If there is an alarm on switch 8, processor 1 finishes managing all operations directly related to the control of reception and transmission of cellular signals, and authenticates this event (or any other depending on the connected external digital device and on the algorithms ny in memory). The processor 1 performs the necessary operations to send a message to the user, which is amplified by the transceiver 2 through the modem 4 and transmitted through the first antenna 3 to the base station 9 of the network operator of the GSM global mobile communications network.

When the command from the base station 9 is received in response to a request for the location of the software, this signal, for example, in the form of a signal for transmitting short messages SMS (Short Message Service) or using packet switching technology in mobile networks GPRS (General Packet Radio Service) is received on the first the antenna 3 of the GSM transceiver 2 is processed by it and fed to the first input-output of the processor 1, as a result of which the processor 1 enters the coordinate request mode. The signals about the coordinates of the geodetic points and software in the coordinate request mode are sent to the second antenna 6 of the GPS receiver 5, then to the second input-output of the processor 1, and the processor 1 processes the signals about the coordinates of the software according to the corresponding signals transmitted from the GPS global positioning system. The processor 1 analyzes the obtained coordinates of the geodetic points and performs an operation to change the data by a given value of the standard deviation of the coordinates. The coordinates of geodetic points and points of the earth's surface with a given standard deviation of the mean square deviation are transmitted from the first i input-output of the processor 1, to the second input-output of the modem 4, amplified by the transceiver 2, and the first antenna 3 are transmitted to the base station 9 of the GSM network operator. Thus, the transceiver 2 transmits telemetry information to a remote terminal of a GSM operator, and also receives commands for changing the state of monitored devices via a radio channel of a GSM cellular communication system. Sources of telemetry information for the claimed design are GPS receiver 5 and I / O port 7. In the claimed design, the input / output port 7 is able to receive information from software sensors in the form of analog, discrete signals, as well as by introducing the switch 8 and in the form of pulse sequences. The capabilities of processor 1 for measuring the pulse repetition rate and their number significantly expand the software monitoring functions. It is possible to exchange data with external devices via CAN-bus or similar data buses. This allows you to connect various external devices to the terminal, for example: to exchange data with the standard electronic systems of cars. The combination of reprogrammable analog and digital inputs, as well as outputs, allows you to implement all the functions of software protection, as well as improve performance, improve reliability and simplify the design. It is possible to use existing terminal housings without significant refinement of their design and a significant change in the software of processor 1. Thus, it is possible to improve the basic technical and operational characteristics of the terminal when it operates in software location mode. The most successfully announced mobile communication terminal may be industrially applicable when implementing the security function and determining the location of software.
