Description

The invention relates to mobile communication devices, namely, to individual means of cellular communication, specifically to cellular telephone sets, and may find application in the manufacture of the latter.

Known mobile communication device described in patent RU 2199183, publ. 2002.09.20, comprising an antenna, receiving and transmitting units, as well as a monitoring and control unit with permanent and random access memory, a subscriber identity module (SIM card), a keyboard, a display and a power supply unit interconnected via a system bus containing a data bus , address bus and control bus. The known device allows you to selectively select the choice of a service provider, depending on whether he is an authorized provider or not, and on this basis to provide or not to ensure the initialization of a mobile device for communication. However, it does not solve the problem of providing reliable communication in areas of poor reception of the used mobile operator, although base stations of other operators with a stable coverage area operate in the same area.

A well-known mobile phone is configured to switch from a public network to a private network (CN 108055682, publ. 2018.05.18), while for it a public and private network can be combined with high-speed 4G Internet for sharing. When the performance of one network decreases, the phone automatically switches to another, while the user does not feel the network switch and service during the switch is not interrupted. This method can be used by users of existing networks of domestic and foreign operators, which will minimize the cost of creating a new network. However, the ability to switch a known telephone during communication to a more efficient mobile operator using one identifying module of a subscriber and one information channel does not fully solve the problem of reliability of information delivery, as well as its reliability and secrecy.

Closest to the claimed is a cell phone (RU 2319322, publ. 2008.03.10), which contains an antenna, receiving and transmitting units, a control and management unit with a permanent and random access memory unit, a subscriber identity module block - a SIM card block, a keyboard, a display and a power supply unit interconnected by a system bus including a data bus, an address bus, and a control bus. In addition, a well-known cell phone contains the necessary elements for work: an analog-to-digital converter (ADC), a speech encoder, a channel encoder, a channel decoder, a speech decoder, a digital-to-analog converter (DAC), an equalizer, a message encryption and decryption unit, a voice detector activity, as well as the case and terminal elements. According to the developers, thanks to the block of subscriber identification modules, through the controller and the system bus connected to the monitoring and control device, the well-known technical solution makes it possible to connect the telephone numbers of different mobile operators using one telephone, use different numbers for business and personal calls, for their and outsiders, do not use roaming, staying in touch at the same time in two different cities, and also compare the quality of services provided by different operators and.

It should be noted right away that comparing the quality of communication, its cost and the benefits of additional services provided by different operators makes sense and is correct only in such conditions that during the transition from one subscriber identifier to another remain identical, which is almost impossible to implement, especially for different tracks with different operators.

In addition, if there are several subscriber identifiers (SIM card block) in the known device in the receive-transmit mode, only one of them is used, the rest work in the detection mode, and only one reception or only transmission is realized in one time interval, which is associated with the use of a known device either with one or omnidirectional antenna, or with an antenna with a limited width of the directivity. The use of one information channel does not provide high reliability of information delivery and its reliability, while the channel capacity in some cases is insufficient and limits the transmission speed of information, especially in cases where the subscriber receives with an increased level of errors, which leads to the need for retransmission parts of packages.

The objective of the invention is to develop a mobile communication device with advanced capabilities and providing reliable, high speed information delivery, in accordance with the requirements of reliability and secrecy.

The technical result of the proposed device is to increase the reliability of information delivery while increasing its transmission speed and increasing secrecy by dividing the content into parts and delivering it to the subscriber through various mobile operators to obtain information via parallel channels, as well as to neutralize and reduce the influence of various harmful factors, including the possible failure of one of the mobile operators, due to the simultaneous use of several different operators.

The specified technical result is achieved by a cell phone containing a receiver unit, a transmitter unit, a control and management unit with a permanent and random access memory unit, a keyboard, a display, a power supply unit, a voice communication unit, a voice activity detector, an encryption-decryption unit, analog-to-digital (ADC) ) and digital-to-analog (DAC) converters, an encoder and a decoder for speech, an encoder and a decoder for a channel, and an equalizer interconnected via a system bus, which includes a data bus, address bus, and control bus, as well as at least two subscriber identity modules combined in a unit connected to a control control unit via a controller and a system bus equipped with an antenna and placed in a housing with connected terminal elements, which, unlike the known one, additionally contains a second controller, a second block of modules the subscriber’s identification, the second transmitter unit and the second receiver unit, two additional power supplies configured to monitor, control and recharge, and three additional antennas, while the first an antenna coupled to the first receiver unit, the second controller via a system bus connects the second unit with the subscriber identity module control and the control unit, which in turn is coupled to the second antenna via the first transmitter unit is powered by a second power supply; the third antenna interacts with the second transmitter unit, which is powered from the third power supply unit and is connected to the monitoring and control unit via a system bus; the fourth antenna interacts with the second receiver unit, which is connected through the system bus to the monitoring and control unit.

For ease of use, mounts for additional units and terminal elements are provided on the cell phone case.

The drawing shows a block diagram of the proposed cell phone, comprising the following structural elements: receiver unit 1, transmitter unit 2; control and management unit 3; block of constant and random access memory 4; keyboard 5; display 6; power supply unit 7; voice communication unit 8, voice activity detector 9; block encryption-decryption 10; analog-to-digital (ADC) 11 and digital-to-analog (DAC) 12 converters; an encoder 13 and a speech decoder 14, an encoder 15; channel decoder 16; equalizer 17; system bus 18 (which includes a data bus, an address bus, and a control bus that are not shown in the drawing); Subscriber Identity Modules (SIM cards) 19 assembled in block 20, controller 21. The block diagram includes an antenna 22 and a housing 23 with terminal elements 24. In accordance with the proposed technical solution, the block diagram includes a second controller 25, a second block 26 subscriber identity modules 19; a second antenna 27 and a second power supply 28, configured to monitor, control and recharge; a third antenna 29, a second transmitter unit 30, and a third power supply unit 31, also configured to monitor, control, and recharge; a fourth antenna 32 and a second receiver unit 33.

Coordination of the work of all nodes of the cell phone is carried out by the control and control unit 3, which is a digital signal processor (CPU) with read-only memory (ROM), which contains a program that coordinates the operation of the processor, and random access memory (RAM), designed for temporary storage data and results of logical or mathematical operations that are performed by the aforementioned processor.

The controller 21 provides the interaction of the control and management unit 3 with each of the subscriber identity modules 19 installed in the block 20. The presence in the proposed cell phone of a second controller 25 connecting the second block 26 of the subscriber identification modules 19 with block 3, when the antenna 22 is operating in the reception mode provides the passage of incoming signals through the receiver block 1 to block 3 and further, through the corresponding elements of the device, to the terminal elements intended for their reception: to the microphone, to the screen (s) for receiving, respectively spawning SIM, in the memory unit, etc.

The presence of two blocks, each of which contains several subscriber identity modules, and several (at least two) simultaneously operating blocks of transmitters and receivers, each with its own antenna, makes it possible to realize the simultaneous operation of several information channels and expand the technical capabilities of a mobile communication device.

The connection of the monitoring and control unit 3 with the second 27 antenna through the transmitter unit 2 allows “on behalf of” one of the SIM cards of the first or second unit to transmit data for the selected subscriber via the corresponding (selected SIM card) base stations.

The use of additional power supplies, made with the ability to control, control and recharge, provides an increase in the temporary and energy resource of communication.

Thanks to the above-described combination of elements with new connections, the proposed cell phone allows simultaneously, with appropriate diversity of the receiving and transmitting antennas, to exchange information with other subscribers, at least “on behalf of” two SIM cards (one through each of the two controllers 21 and 25).

The presence of a second controller allows you to distribute the data stream according to a given subscriber protocol. Data from different SIM cards, as a standard, passes through different base stations and, possibly, from different mobile operators, reaches the mobile phone (proposed design) of the subscriber-recipient of information, where they are connected. In other words, one part of the message goes to the subscriber (or subscribers), for example, via MTS, and the other through MegaFon, which allows parallel exchange of various data: video, sound, photos, text in different formats, etc.

The antennas used in the proposed cell phone (in the amount of four) can be spatially spaced according to its maximum dimensions or can be attached to its body, for example, in the form of remote antennas. The envisaged possibility of increasing the spacing of the antenna elements and the size of the antennas themselves allows you to strengthen their directional properties for both reception and transmission. An increase in the directional properties of the antennas leads to an increase in their gain, which improves signal selection in direction and increases the signal-to-noise ratio, and also improves the reliability and stability of communication (reduce the likelihood of errors, reduce the time for retransmission, increase the throughput of the communication channel and phone as part of a cellular communication system). In addition, the presence of several antennas allows you to implement, taking into account electromagnetic compatibility, guidance modes and to form the exact direction of the base station antennas, thereby increasing the signal to noise ratio.

The possibility of implementing the proposed device is based on the fact that its structural elements and functional blocks are almost identical to those used in the well-known telephone. The arrangement of these elements is new, the connection between them and, as a result, the new device as a whole discovers a number of new properties.

The work of the proposed phone, as well as the known one, chosen as the closest, is generally similar to the work of a regular cell phone with one SIM card.

In case if several SIM-cards of different (or one) mobile communication operators (prototype) are installed on the phone and several call signals are received simultaneously on the phone, depending on the design features of the mobile communication device, taking into account the standard chosen by the user, the display will either be activated simultaneously corresponding sectors, or inscriptions of the type “conversation 1”, “conversation 2”, etc., appear sequentially. with the designation of the respective mobile operator.

The user needs to make a choice of one or another of the calls received at the same time, which he makes by pressing the corresponding digital key of the phone 1, 2, 3, etc., the number of which is determined by the number of installed SIM-cards. If the second call arrives at the time of the call, then the second caller in the handset will hear the usual short beeps indicating the busy line, or he will be sent a sound warning or apology, for example, “please wait one minute” or “call back later”, set at the user's choice.

At the same time, a significant difference between the content delivery process, in which the main role belongs to the proposed cell phone, is the possibility of implementing the said delivery through various mobile operators operating simultaneously, i.e. using parallel channels, which, coupled with other essential features, provides new features of this phone and its advantages.

So, when using the proposed cell phone due to the simultaneous receipt of information on parallel channels with the possibility of comparing and deciding on the compliance of the received information with the reliability requirements, the reliability of content delivery is significantly improved while maintaining the required volume and quality. The joint use of at least two telephone numbers of various mobile operators allows the recipient to verify the reliability of the information received (one serves as a source of information, and the second is a guarantee of its authenticity).

By dividing the content into parts and delivering it to the subscriber in parts through various operators, the transmission speed increases, the process of delivering information, including video, speech, music, SMS, WhatsApp, etc., is accelerated, and at the same time, the secrecy of information increases.

In addition, the delivery of content in parts using various operators can reduce the impact on the quality of delivery of numerous harmful factors, which, in particular, include: an increased level of interference along delivery routes, interference, fading in space, the dependence of the course of radio waves on natural phenomena, accompanied by changes during the day and during the year, various Doppler signal deformations caused by radial velocities between the mobile phone and the base station, and others, as well as reduce the negative impact on the output of the content delivery system of one of the base station of the cellular operators.

Using the proposed phone also allows for a correct comparison of the delivery conditions of a particular content by various mobile operators in real time, to evaluate the quality of communication, its cost and additional services provided by different operators; and choose the best.
