Description

The invention relates to mobile wireless communication devices, in particular, to cellular telephones with advanced technical capabilities that are capable of operating in receiving, transmitting, relaying modes over one or two physical channels, and can be used to provide reliable stable communication in an area of unstable information exchange, including those caused by excessive network congestion, as well as to reduce the total intensity of the electromagnetic field created by working mobile phones and reduce its impact on the user’s body and others.

The problems of reliable mobile communications are relevant not only for remote areas; they arise in urban semi-basement offices and shopping centers, in tunnels, and in buildings with complex floor structures. In addition, the constant increase in the volume of information transmitted through mobile communication networks, especially in large cities with developed infrastructure, requires a continuous search for optimal methods for ensuring electromagnetic compatibility. One solution to the problem is to organize additional communication channels using orthogonal physical signals.

It should be taken into account that each type of signal has its own characteristics. It is known that to use an optical laser signal, direct visibility between subscribers’ mobile devices is required, which does not allow organizing an optical channel in a space filled with people, for example, in a public transport cabin. Acoustic signals have greater penetrating power, but have a short range.

Radio signals differ from the physical signals mentioned above in that they have a significantly greater harmful effect on biological objects, including the human body. However, the problem of restricting users from using cell phones in public transport, which is one of the most important today, still requires a solution

A mobile phone is known that is capable of switching from a public cellular network to a private one (CN108055682, publ. 2018.05.18), while for it the public and private networks can be combined with high-speed 4G Internet for shared use. When the performance of one network deteriorates, the phone automatically switches to another without the user experiencing a network switch and without interrupting service during the switch. The use of this method by various operators of existing networks in practice makes it possible to minimize the costs of creating a new cellular network. However, the ability to switch a known telephone during communication to a more productive operator does not completely solve the problem of increasing communication reliability in an area of unstable information exchange or in the event of a lack of communication, for example, frequency, resource due to a large number of simultaneously operating subscriber cellular devices. In addition, due to its design features, the known telephone cannot provide adequate protection to the user from electromagnetic radiation, the intensity of which increases during communication with the base station in areas of poor reception, as well as in the case of a high concentration of active subscribers per unit area, for example, in public transport. In addition, the known telephone does not have the ability to simultaneously conduct information exchange via two physical channels with orthogonal signals.

There is a known method (WO 2019207388, publ. 2019.10.31) for establishing acoustic communication between closely spaced electronic devices, according to which said devices are placed so that their screens face each other, and the upper part of one electronic device is located opposite the lower part of another electronic device . The first and second devices exchange synchronization signals, and the transmitted acoustic signal is adjusted so that acoustic communication occurs in a given frequency range at a certain range and transmission speed, providing a frequency bandwidth per channel of 600 Hz, which allows for large clusters of active subscribers, dozens of information channels that do not interfere with each other. This is enough for use on an airplane, bus, or train. However, according to the known method, they use sequentially: first an acoustic and then a radio channel; there is no simultaneous operation (interfacing) of channels, which does not allow organizing cross-exchange along possible additional trajectories: radio - acoustics, acoustics - radio, acoustics - acoustics. Monitoring physical channels provides the opportunity to assess their quality, but there is no possibility of comparing them, which does not allow choosing a channel that is effective according to given criteria. The narrow specialization of each physical channel does not allow traffic harmonization.

As the closest to the proposed one, a cell phone with repeater functions was selected, capable of providing communication between a subscriber located in the area of unstable information exchange and the nearest base station by transit communication through a cell phone located in an area of reliable reception (RU 2754639, publ. 2021.09. 06), which contains a receiver, a transmitter, a monitoring and control unit with permanent and random access memory units, a keyboard, a display, a power supply, a voice communication unit, a voice activity detector, an encryption-decryption unit, analog-to-digital and digital-to-analog converters located in the housing, a speech encoder and decoder, a channel encoder and decoder, as well as an equalizer, with all its nodes and components interconnected by a system bus containing a data bus, an address bus and a control bus; In addition, the known telephone includes at least two subscriber identification modules combined into a unit connected via a system bus to a controller connected to a monitoring and control unit, and additionally contains a second monitoring and control unit, a second controller, as well as a relay support unit combining It includes electronic modules for identifying subscribers, owners of cell phones with a relay function, a relay receiver with a receiving antenna, and a relay transmitter with a transmitting antenna.

The known telephone is not capable of simultaneously carrying out information exchange through two physical channels with orthogonal signals, which, in the case of insufficient communication resources, as well as in an overloaded network, makes this exchange difficult and makes it unreliable. In addition, with a high density of active subscribers per unit area and an increased level of radiation from cell phones and, accordingly, an increased intensity of their electromagnetic field, the danger of harmful effects on the bodies of users and others increases.

The objective of the invention is to develop a cell phone design that provides reliable and secure information exchange for subscribers located in an area of insufficient communication resources, as well as in an overloaded network and in the case of a high density of active subscribers per unit area.

The technical result of the proposed cell phone is to ensure stable information exchange in an area of insufficient communication resources while simultaneously reducing the total intensity of the electromagnetic field created by working mobile phones, affecting users and others, in the case of a high density of active subscribers per unit area through the use of two physical channels with orthogonal signals and transmitting part of the radio traffic over an acoustic channel.

The specified technical result is achieved by a cell phone containing a receiver, a transmitter, a monitoring and control unit with permanent and RAM memory, a keyboard, a display, at least two electronic subscriber identification modules connected through a controller to the system bus, a power supply, and a voice communication unit placed in a housing. , voice activity detector, analog-to-digital and digital-to-analog converters, speech encoder and decoder, channel encoder and decoder, as well as an equalizer, interconnected via the system bus, at least two electronic modules, subscriber identification, connected via a controller to system bus, the composition of which, unlike the known one, additionally contains at least two electronic subscriber identification modules involved in the implementation of acoustic communication channels and connected to the second controller, in turn, through the system bus connected to the second monitoring and control unit, equipped with a constant and RAM, and also includes an acoustic receiver with a receiving antenna and an acoustic transmitter with a transmitting antenna, connected to the system bus.

The drawing shows a block diagram of the proposed cell phone, which includes the following structural elements: housing 1, receiver 2, transmitter 3, monitoring and control unit 4, equipped with permanent and RAM memory, keyboard 5, display 6, power supply 7, unit voice communication 8, voice activity detector 9, encryption-decryption unit 10, analog-to-digital (ADC) 11 and digital-to-analog (DAC) 12 converters, speech encoder 13 and decoder 14, channel encoder 15 and decoder 16, as well as equalizer 17, associated each other via the system bus 18. The proposed phone also contains at least two electronic subscriber identification modules 19, connected via a controller 20 to the system bus 18. In addition, the cell phone contains at least two electronic subscriber identification modules 21 involved in ensuring the implementation of acoustic channels communications. The mentioned modules 21 are connected to the second controller 22, which, in turn, is connected via the system bus 18 to the second monitoring and control unit 23, equipped with permanent and random access memory. An acoustic receiver 24 with a receiving antenna and an acoustic transmitter 25 with a transmitting antenna are also connected to the system bus 18.

The monitoring and control unit 4 is a digital signal processor (DSP) with a read-only memory (ROM), which contains a program that coordinates the operation of the processor, and a random access memory (RAM) designed for temporary storage of data and the results of logical or mathematical operations, which are produced by the aforementioned processor. The operation of the acoustic part of the device is coordinated by the second monitoring and control unit 23, which is subordinate to the monitoring and control unit 4 and coordinates its work with it. The controller 20 ensures the interaction of the monitoring and control unit 4 with each of the subscriber identification modules 19, while the second controller 22 similarly ensures the interaction of the corresponding monitoring and control unit 23 with the electronic subscriber identification modules 21 (remotely configured and reconfigured by command from base stations using e-SIM cards). The use of electronic SIM cards allows, in a specific situation, to download from the base station of the nearest cellular operator the data necessary to implement the acoustic mode of information interaction.

The second controller 22, connecting the electronic subscriber identification modules 21 of the relaying cell phone, is connected to the second monitoring and control unit.

In relay mode, the signal from the acoustic receiver 24 through the system 18 bus enters the second monitoring and control unit 23, in which the address of the message recipient is determined. And if it corresponds to the address of the subscriber located in the database (DB) of acoustic channels, then the second monitoring and control unit 23, again through the system bus 18, transmits the message to the acoustic transmitter 25, equipped with an antenna, for radiation. If the address of the message recipient is not in the DB, the input signal is transmitted to the monitoring and control unit 4. If this address corresponds to this device or the address of the message recipient is present in the radio channel DB, then the parameters of the radio channel are determined and sent to the transmitter 3 for their emission.

Other options for interaction of device elements are possible to implement different switching modes along the following paths: radio - acoustics, acoustics - radio, acoustics - acoustics and radio - radio. Using simultaneously channels with orthogonal radio and acoustic signals, the user, using the proposed cell phone, can carry out information exchange with subscribers who have similar devices, both in the “point-to-point” relay mode and through a base station configured to work with acoustic signals and with the appropriate protocol. By forming transit communication channels with base stations of other operators, stable information interaction with a subscriber or subscribers located outside the coverage area of the base station is ensured. Reliable communication is created in conditions that do not sufficiently ensure its performance, namely, with a high level of interference for both radio and acoustic signals and/or in the event of their strong weakening. Radio and acoustic signals are orthogonal and do not interfere with each other, while the presence of two physical channels with orthogonal signals makes it possible to parallelize information flows. The mentioned parallelization allows increasing the throughput of a cell phone, and duplicating information and sending it over two physical channels increases the reliability of the transmitted information; The distribution of part of the message over physical channels with different signal parameters increases the secrecy of information exchange necessary in some cases. When there is a high density of active subscribers, for example, in public transport, replacing part of the radio traffic with acoustic traffic reduces the total intensity of the electromagnetic field. At the same time, the danger to the health of the user and others is reduced, communication reliability is improved, and immunity from interference is increased, since the simultaneous deterioration of the interference situation for various physical channels is an unlikely event. The use of the proposed phone with advanced technical capabilities, already in the amount of about 5% of the total mass of cell phones, will allow the cellular operator to relieve tension in case of traffic overload, while qualitatively and quantitatively increasing the efficiency of servicing a large number of subscribers.
