Abstract

FIELD: mobile radio communication. SUBSTANCE: procedure of information transmission to mobile objects consists in arrangement of base stations which coverage zones are set equal to length of leg of each regular hexagon in ideal cells presenting equal regular hexagons tightly covering serviced zone. Different working frequencies of information radio signals emitted by all base stations are specified. Each base station specifies one working frequency for radio signals emitted by this base station from specified working frequencies. Each mobile object located within limits of serviced territory is assigned with working frequencies of information radio signals received by this mobile object. Information radio signals corresponding to information transmitted to mobile objects located within limits of serviced territory are transmitted by one base station which is source of transmitted information to base stations in which coverage zones mobile objects are located. From these base stations information radio signals corresponding to information are emitted to mobile objects located within coverage zones of these base stations and information radio signals are received on specified working frequencies. Base stations are positioned in vertexes of specified regular hexagons. Number of specified working frequencies is equal to six. Working frequency of radio signals specified for each base station arranged in vertex of regular hexagon and emitted by this base station is one from six assigned working frequencies different from specified working frequencies of radio signals emitted by adjacent base stations which are base stations located in adjacent vertexes of these regular hexagons. Working frequencies of information radio signals specified for each mobile object and received by this mobile object are five different working frequencies from specified six frequencies. Information signals corresponding to information transmitted to mobile objects located within limits of serviced territory are corresponding information radio signals. Transmission of these information radio signals by base station which is source of transmitted information to base stations in which coverage zones mobile objects are located consists in that base station which is source of transmitted information emits information radio signals on specified working frequency and in simultaneous reception of information radio signals at all base stations adjacent with reference to base station which is source of transmitted information and their emission on corresponding specified working frequencies. Then all other base stations which are adjacent with reference to specified base stations simultaneously receive information radio signals emitted by specified base stations and emit them on corresponding specified working frequencies. Information radio signals emitted by previous base stations are simultaneously received and emitted on corresponding specified working frequencies thereupon in same manner, consistently, along all directions from base station which is source of transmitted information to boundaries of serviced territory by all other following base stations which are adjacent with reference to previous base stations. Each base station except base station which is source of transmitted information emits information radio signals on specified working frequency and receives information radio signals on one working frequency specified for this base station. Each base station measures power of information radio signals received from adjacent base stations. After this each base station emits service radio signals carrying information on measured value of power. Each specified adjacent base station receives specified service radio signals and adjusts power of emitted information radio signals by measured values of power of information radio signals received by base stations which are adjacent with reference to specified adjacent base station and emitted by this base station. EFFECT: simplified procedure and raised quality of reception of information by mobile objects on basis of rational positioning of base stations on serviced territory. 6 dwg

Description

 The invention relates to techniques for mobile radio communications, and in particular to methods for transmitting information to moving objects.

 There is a method of transmitting information to moving objects in personal radio call systems (see, for example, Gromakov Yu.A. Standards and mobile radio communication systems. - M.: Eco-Trends, 2000, p. 10-52), which consists in the fact that a radio transmitting station with a coverage area covering the served territory is placed on the served territory, information radio signals corresponding to the information transmitted to mobile objects located within the served territory are emitted from this radio transmitting station associated mobile objects is performed receiving these information signals.

 The specified method allows using one radio transmitting station to transmit information to all mobile objects located within the served territory. However, when transmitting information to moving objects located within a sufficiently vast served territory, the method requires a significant increase in the power of the emitted information radio signals, which affects the environmental and economic quality indicators of the method.

 A known method of transmitting information to moving objects in cellular radio communication systems (see, for example, Ratinsky MV Fundamentals of cellular communications. Edited by DB Zimin. - M .: Radio and communications, 2000, S. 20-68 ), consisting in the fact that in the centers of conditional cells, which are equal regular hexagons, densely covering the served territory, base stations with radiuses of coverage equal to the side length of each regular hexagon are placed, seven different operating frequencies of information radio signals emitted from all bases are set stations and received at mobile objects within the service area, out of seven preset operating frequencies at each base station, one operating frequency of information radio signals emitted from this base station is set, different from the set operating frequencies of information radio signals emitted from neighboring base stations, information optical signals corresponding to information transmitted to mobile objects located within the served territory are transmitted from one of the base stations, the main source of the transmitted information, through the fiber-optic communication line to the switching center, in the switching center, the base stations are determined, in the areas of which mobile objects are located, then information optical signals corresponding to the transmitted information are transmitted from the switching center via optical fiber communication lines to these base stations, from these base stations emit information radio signals corresponding to the transmitted information on mobile objects located in the areas of operation These base stations receive information radio signals at the corresponding given operating frequencies.

 The specified method allows the use of relatively low-power radio transmitting devices located at base stations when transmitting information to mobile objects located within a fairly vast served territory.

раз больше радиусов зон их действия. В связи с этим при передаче информации на подвижные объекты, находящиеся в пределах обслуживаемой территории, способ не позволяет с помощью радиопередающей аппаратуры, размещаемой на базовых станциях, осуществлять передачу информации с базовой станции, являющейся источником передаваемой информации, на другие базовые станции путем излучения информационных радиосигналов с базовой станции, являющейся источником передаваемой информации, приема этих информационных радиосигналов на всех соседних базовых станциях, излучения их с последних базовых станций и дальнейшей последовательной передачи этой информации аналогичным образом на все другие базовые станции, а предусматривает передачу информации через центр коммутации с помощью оптоволоконных линий связи, соединяющих центр коммутации с базовыми станциями, что существенно усложняет способ.However, since the placement of base stations is carried out in the centers of conditional cells, which are equal regular hexagons, densely covering the served territory, and the radii of the coverage areas of base stations are equal to the length of the side of each regular hexagon, the distance between any two neighboring base stations in

times the radii of their zones of action. In this regard, when transmitting information to mobile objects located within the served territory, the method does not allow using radio transmitting equipment located at base stations to transmit information from the base station, which is the source of the transmitted information, to other base stations by emitting radio information signals from the base station, which is the source of the transmitted information, the reception of these information radio signals at all neighboring base stations, their radiation from the last x base stations and further sequential transmission of this information in a similar way to all other base stations, and provides for the transfer of information through the switching center using fiber optic communication lines connecting the switching center to the base stations, which significantly complicates the method.

 However, the method does not allow the transmission of information to moving objects without determining the base stations in the areas of which these moving objects are located, which greatly complicates the method.

 In addition, since the coverage areas of neighboring base stations overlap slightly, within the central sections of the coverage area of each base station, informational radio signals are distributed only in one of seven preset operating frequencies, and therefore informational radio signals are received at each of the moving objects when moving around the serviced the territory must be carried out at all seven given operating frequencies, which also complicates the method.

 Along with this, with the indicated parameters of the relative positions of the base stations on the served territory and the set values of the radii of the coverage areas of the base stations, the method does not allow reception of these information radio signals at neighboring base stations when measuring information radio signals from each base station, measuring their power and adjusting each base station power stations of the emitted information radio signals according to the measured power values, which leads to a decrease in the quality of information reception and moving the object while changing the radii of coverage areas of base stations due to changes of propagation conditions.

The method of transmitting information to mobile objects, adopted as a prototype, is used in cellular radio communication systems, for example, when transmitting call signals from one of the base stations to several mobile objects located within the served territory for conference communication. (See, for example, Ratinsky M.V. Fundamentals of Cellular Communications. Ed. By D. B. Zimin. - M.: Radio and Communications, 2000, p. 61.)
The technical problem to be solved is to simplify the method and improve the quality of information reception on mobile objects based on the rational placement of base stations in the served territory.

 The solution to the technical problem in the method of transmitting information to moving objects, which consists in the fact that in conditional cells, which are equal regular hexagons, densely covering the served territory, base stations are placed, the radii of which are set equal to the length of the sides of each regular hexagon, set different working the frequencies of the radio signals emitted from all base stations, from the given operating frequencies at each of the base stations, one working frequency of the radio signals is set, emitted x from this base station, at each of the mobile objects located within the serviced territory, the operating frequencies of the information radio signals received at this mobile object are set, information signals corresponding to the information transmitted to the mobile objects located within the serviced territory are transmitted from one from the base stations, which is the source of the transmitted information, to the base stations, in the areas of which mobile objects are located, from these base stations emit e information radio signals corresponding to the transmitted information, on mobile objects located in the coverage areas of these base stations, receive information radio signals at specified operating frequencies, achieved by placing the base stations at the vertices of the indicated regular hexagons, the number of specified operating frequencies of the radio signals emitted from all base stations equal to six, set at each base station located at the top of the regular hexagons, the operating frequency of the radio signals emitted from this base station is one of six specified operating frequencies, different from the specified working frequencies of the radio signals emitted from neighboring base stations, which are base stations located at the neighboring vertices of these regular hexagons, defined on each moving object by the working frequencies of the information radio signals received at this moving object are five different of the six specified operating frequencies, information signals corresponding to the information transmitted mine on mobile objects located within the served territory are the corresponding information radio signals, the transmission of these information radio signals from the base station, which is the source of the transmitted information, to the base stations in the areas of which the mobile objects are located, is that from the base station, being the source of the transmitted information, radiation of information radio signals is carried out at a given operating frequency, at all base stations that are neighboring in relation South of the base station, which is the source of the transmitted information, simultaneously receive the information radio signals emitted from the last base station and their emission at the corresponding given operating frequencies, then at all other base stations that are adjacent to the indicated base stations, simultaneously receive the transmitted the specified base stations of information radio signals and their radiation at the corresponding given operating frequencies, then in the same way sequentially, according to all directions from the base station, which is the source of the transmitted information, to the boundaries of the served territory at all other subsequent base stations, which are adjacent to the previous base stations, simultaneously receive information radio signals emitted from previous base stations and emit them at the corresponding given operating frequencies, at the same time, from each base station, except the base station, which is the source of the transmitted information, the radiation of information radio signal s at a given operating frequency is carried out when receiving at this base station informational radio signals of one of the operating frequencies set at this base station, at each base station, the power of the informational radio signals received from neighboring base stations is measured, then service radio signals are emitted from each base station, containing information about the measured power values, at each of these neighboring base stations receive the specified service radio signals and ulirovku power information radio signals emitted from the measured values of the power information radio signals received at the base stations that are adjacent to said adjacent base station and radiated from the base station.

 The term "moving object" is generally accepted. (See, for example, Solovyov Yu.A. Satellite navigation systems. - M .: Eco-trends, 2000, p. 47.) For mobile objects include, for example, various vehicles equipped with radio reception equipment. By the terms “neighboring base station” or “base station that is adjacent to a given base station” we mean base stations located at the closest distance from this base station.

 In FIG. 1 shows conditionally base stations located in the served territory and mobile objects located within the served territory, with a conditional image of the coverage areas of the base stations and an indication of the specified operating frequencies of the radio signals emitted from each of these base stations, for the case in which the number of base stations is fifty-four; the number of mobile objects is five.

 In FIG. Figure 2 shows conditionally base stations located on the served territory and mobile objects located within the served territory, indicating the specified operating frequencies of the radio signals emitted from each of these base stations, as well as with a conditional image of the directions of transmission of information radio signals from one of the base stations , which is the source of the transmitted information, to other base stations, for the case in which the number of base stations is fifty-four, the number of mobile objects is five.

 Figure 3 shows conditionally temporary diagrams of the transmission of information radio signals from the base station, which is the source of the transmitted information, to other base stations.

 In FIG. 4 shows a system for implementing the method for the case in which the number of transceivers, one each in each of the base stations, is twelve, and the number of radio receivers placed one on each of the moving objects is three, and the moving objects in FIG. 4 not shown.

 Figure 5 shows the transceiver, which is part of each of the base stations, and the base station in figure 5 is not shown.

 Figure 6 shows a radio placed on each of the moving objects, and the moving object in figure 6 is not shown.

 In the present description, the following notation is used.

l _n - base station 1 with number n, where n = 1, 2, ..., N are positive integers; 2 _m - movable object 2 with number m, where m = 1, 2, ..., M are positive integers; 3 _n - zone 3 of the action of the base station 1 _n ; f _q is the working frequency of the radio signals emitted from base station 1, where q = 1, 2, ..., Q are positive integers. In cases where this does not lead to misinterpretation, the indices in the above notation are omitted.

 The essence of the method is as follows.

On the served territory, at the vertices of the conditional cells, which are equal regular hexagons, densely covering the served territory, place, as shown in FIG. 1, base stations 1 (base stations 1 ₁ -1 ₅₄ ), the radii of the zones 3 of which are set equal to the length of the side of each regular hexagon.

 With this arrangement of base stations 1 on the served territory, no more than three base stations 1 are adjacent to each base station 1.

 By zone 3 of action of each base station 1 we mean equal to each other zone 3 of action when radiating radio signals from this base station 1 and zone 3 of action when receiving radio signals of this base station 1.

Moreover, by zone 3 of action when emitting radio signals from each base station 1, we mean a part of the territory within which, with undirected radiation from this base station 1, radio signals of power P _{q radiated} at the operating frequency f _{q the} power of these radio signals when they are received at other base stations 1 and 2 on moving objects is not less than a certain threshold value P _pr.min characterizing sensitivity receiving radio channels at the base stations 1 and 2. By moving objects zone 3 acts to radio ignalov at each base station 1 to recognize an area, within which at the omnidirectional radiation from other base stations 1, radio signals of the same power P _{q rad} at the same operating frequency f _q capacity of these radio signals at the omnidirectional reception at the base station 1 is not less than the the same value of P _av.min .

где с - скорость света в вакууме.In this regard, assuming that the propagation of radio waves occurs in free space, and the served area is a plane, the zone 3 of action of each base station 1 with non-directional radiation from base stations 1 and non-directional reception of radio signals at base stations 1 and mobile objects 2 is a circle with a center at the location of this base station 1 and a radius determined by the formula (see, for example, Theoretical Foundations of Radar. Edited by V.E. Dulevich. - M.: Soviet Radio, 1978, p.402 )

where c is the speed of light in vacuum.

 By the radius of the zone 3 of the action of each base station 1 we understand the radius of the specified circle.

 When placing base stations 1 at the vertices of conditional cells, which are equal regular hexagons, densely covering the served territory, with radii of zones 3 of action of base stations 1 equal to the length of the side of each regular hexagon, the border of zone 3 of action of each base station 1 passes through the points of placement of neighboring base stations 1. In Fig.1, the boundaries of the zones 3 of the action of base stations 1 are shown conditionally by circles.

В способе применяют информационные и служебные радиосигналы. Если в настоящем описании вид радиосигналов не уточняется, то ими могут являться и информационные, и служебные радиосигналы.In the present description, by the term “signal power” we mean the average signal power P signal s (t), determined in the time interval t _a ≤ t ≤ t _b , by the formula (see, for example, A. Trakhtman. Introduction to the generalized spectral theory Signals. - M .: Soviet Radio, 1972, p.14)

The method uses information and service radio signals. If in the present description the type of radio signals is not specified, then they can be both information and service radio signals.

 Six different operating frequencies (Q = 6) of the radio signals emitted from all base stations 1 are set. Of the six preset operating frequencies at each base station 1, one, as shown in FIG. 1, is set to one operating frequency of radio signals emitted from this base station 1, different from the specified operating frequencies of the radio signals emitted from neighboring base stations 1. Thus, at base stations 1 that are not adjacent, the repeating operating frequencies of the radio signals emitted from these base stations 1 are set.

 By the term "operating frequency" we mean the value of the frequency of the carrier wave, the central or some other characteristic value of the frequency of the frequency band of radio signals. Moreover, the frequency bands of the radio signals corresponding to different operating frequencies are non-overlapping.

 Information signals corresponding to information transmitted to mobile objects 2 located within the served territory are transmitted from one of the base stations 1, which is the source of the transmitted information, to base stations 1, in the zones of action 3 of which mobile objects 2 are located. From these base stations 1 carry out the emission of information radio signals corresponding to the transmitted information. In this case, information signals corresponding to information transmitted to mobile objects 2 located within the service area are the corresponding information radio signals.

 The transmission of informational radio signals from the base station 1, which is the source of the transmitted information, to the base stations 1, in the zones of action 3 of which are moving objects 2, is as follows. From the base station 1, which is the source of the transmitted information, radiation of information radio signals is carried out at a given operating frequency. Moreover, at all base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, simultaneously receive information radio signals emitted from the last base station 1 and their radiation at the corresponding given operating frequencies. Then, at all other base stations 1, which are adjacent to the indicated base stations 1, simultaneously receive information radio signals emitted from the indicated base stations 1 and their radiation at the corresponding given operating frequencies. Then, in the same way, sequentially, in all directions from the base station 1, which is the source of the transmitted information, to the boundaries of the served territory at all other subsequent base stations 1, which are adjacent to the previous base stations 1, they simultaneously receive the signals emitted from the previous base stations 1 information radio signals and their radiation at the corresponding given operating frequencies.

 To ensure the transmission of informational radio signals from the base station 1, which is the source of the transmitted information, to the base stations 1, in zones 3 of which there are movable objects 2, and therefore to all other base stations 1, without "looping" at each base station 1 in addition to the base station 1, which is the source of the transmitted information, the operating frequencies of the information radio signals received at this base station 1 are set, at which the information radio is emitted from this base station 1 ignalov at a predetermined operating frequency.

So, for example, as shown in figure 2, from the base station 1 _{29 the} radiation of information radio signals at a given operating frequency f _{1 is} carried out when receiving at this base station 1 ₂₉ information radio signals of one of the operating frequencies f ₂ and f specified at the base station 1 _{29 4} , which are the working frequencies of information radio signals emitted from base stations 1 ₃₅ and 1 _23, respectively. At the same time, from the base station 1 _{19, the} emission of information radio signals at a given operating frequency f _{1 is} carried out regardless of the values of the operating frequencies of the information radio signals emitted from neighboring base stations 1, since in the above example, the base station 1 ₁₉ is a source of transmitted information.

 In figure 2, the directions of transmission of informational radio signals from each base station 1 to neighboring base stations 1 when transmitting informational radio signals in all directions from base station 1, which is the source of the transmitted information, are arbitrarily shown to the boundaries of the served territory.

The transmission of information radio signals from the base station 1 ₁₉ , which is the source of the transmitted information, to the base stations 1, in the zones 3 of which are moving objects 2, as shown in figure 2, is as follows. From the base station 1 ₁₉ , which is the source of the transmitted information, radiation of information radio signals is carried out at a given operating frequency. Moreover, at all base stations 1 (base stations 1 ₁₄ , 1 ₂₅ , 1 ₂₄ ), which are adjacent to the base station 1 ₁₉ , which is the source of the transmitted information, simultaneously receive information radio signals emitted from the last base station 1 and their radiation to corresponding given operating frequencies. Then, at all other base stations 1 (base stations 1 ₁₀ , 1 ₂₀ , 1 ₃₁ , 1 ₃₀ , l ₁₈ , 1 ₉ ), which are adjacent to the indicated base stations 1 (base stations 1 ₁₄ , 1 ₂₅ , 1 ₂₄ ) simultaneously carry out the reception of information radio signals emitted from the indicated base stations 1 and their emission at the corresponding predetermined operating frequencies. Then, in the same way, sequentially, in all directions from the base station 1 ₁₉ , which is the source of the transmitted information, to the borders of the served territory at all other subsequent base stations 1 (first, at the base stations 1 ₆ , 1 ₁₅ , 1 ₂₆ , 1 ₃₇ , 1 ₃₆ , 1 ₃₅ , 1 ₂₃ , 1 ₁₃ , 1 ₅ , then at base stations 1 ₂ , 1 ₃ , 1 ₁₁ , 1 ₂₁ , 1 ₃₂ , 1 ₄₂ , 1 ₄₁ , 1 ₄₀ , 1 ₂₉ , 1 ₁₇ , 1 ₈ , 1 ₁ , then at the base stations 1 ₇ , 1 ₁₆ , 1 ₂₇ , 1 ₃₈ , 1 ₄₇ , 1 ₄₆ , 1 ₄₅ , 1 ₄₄ , 1 ₃₄ , 1 ₂₂ , 1 ₁₂ , 1 ₄ , then at the base stations 1 ₃₃ , 1 ₄₃ , 1 ₅₁ , 1 ₅₀ , 1 ₄₉ , 1 ₄₈ , 1 ₃₉ , 1 ₂₈ and finally at base stations 1 ₅₄ , l ₅₃ , 1 ₅₂ ), which are adjacent in relation communication to the previous base stations 1, simultaneously receive the information radio signals radiated from the previous base stations 1 and their radiation at the corresponding predetermined operating frequencies.

 The schemes shown in FIG. 1 and FIG. 2 are examples of placing base stations 1 in a served territory with radiuses of action zones 3 equal to the side length of each regular hexagon, and setting at each base station 1 the operating frequency of the radio signals emitted from this base station 1, as well as tasks at each base station 1, except for base station 1, which is a source of transmitted information, operating frequencies of information radio signals received at this base station 1, at which from this base station 1 suschestvlyayut radiation of radio information at a given operating frequency.

With the indicated placement parameters on the served territory of base stations 1 with the specified radii of action zones 3 at each point of the served territory, at least two action zones 3 of neighboring base stations 1 overlap. Since the emission of information radio signals from neighboring base stations 1 is carried out at different operating frequencies, each the receiving point receives information radio signals of at least two different specified operating frequencies. (So, for example, as shown in Fig. 1, a moving object 2 ₁ is located in zones 3 of two base stations 1 ₉ and 1 ₁₄ , from which radiation of information radio signals is carried out at operating frequencies f ₅ and f _4, respectively.) Therefore, to ensure guaranteed reception of informational radio signals on moving objects 2 when they move within the service area, it is sufficient to receive informational radio signals on each moving object 2 only at five different out of six specified operating frequencies.

 On mobile objects 2, information radio signals emitted from base stations 1 are received, in the zones of action 3 of which these mobile objects 2 are located. At the same time, information radio signals on mobile objects 2 are received at specified operating frequencies, which are five different on each mobile object 2 of six given operating frequencies.

To ensure the operability of the method, the placement of base stations 1 near the boundaries of the served territory must be carried out so that at each point of the served territory there is an overlap of at least two zones 3 of the activity of neighboring base stations 1. So, for example, the border of the served territory shown in Fig. be a closed polygonal line passing through all the extreme base stations 1 (base stations 1 ₁ , 1 ₅ , 1 ₂ , 1 ₆ , 1 ₃ , 1 ₇ , 1 ₁₁ , 1 ₁₆ , 1 ₂₁ , 1 ₂₇ , 1 ₃₃ , 1 ₃₈ , 1 ₄₃ , 1 ₄₇ , 1 ₅₁ , 1 ₅₄ , 1 ₅₀ , 1 ₅₃ , 1 ₄₉ , 1 ₅₂ , 1 ₄₈ , 1 ₄₄ , 1 ₃₉ , 1 ₃₄ , 1 ₂₈ , 1 ₂₂ , 1 ₁₇ , l _l2 , 1 ₈ , 1 ₄ ).

When transmitting information to moving objects 2 in the conditions of propagation of radio waves in free space, in order to ensure a given value of the radius R of the zone 3 of action of each base station 1 with known values of the operating frequency f _q and sensitivity P _pr.m. ) provide the desired power value P _{q rad} emitted information signals. However, when the propagation conditions of radio waves deteriorate, which occurs, for example, when the base stations 1 are shaded and when the radio waves attenuate in the atmosphere, the radius of the zones 3 of the base stations 1 decreases, which leads to a decrease in the quality of information reception at moving objects 2. Therefore, to ensure the required quality receiving information on moving objects 2 at each base station 1, it is necessary to adjust the power of the emitted information radio signals.

 In the method, at each base station 1, the power of the information radio signals received from neighboring base stations 1 is measured. Then, overhead radio signals containing information about the measured power values are emitted from each base station 1. At each of the indicated neighboring base stations 1, the indicated radio signals are received and the power of the emitted information radio signals is adjusted according to the measured values of the power of the information radio signals received at the base stations 1, which are adjacent to the indicated neighboring base station 1, and emitted from this base station 1 .

In accordance with the scheme shown in figure 1, at each base station 1 (for example, at base stations 1 ₆ , 1 ₁₅ , 1 ₁₄ ) measure the power of information radio signals received from neighboring base stations 1 (from base station 1 ₁₀ and from other base stations 1, which are adjacent to base stations 1 ₆ , 1 ₁₅ , 1 ₁₄ ). (Base stations 1 ₂ , 1 ₃ , 1 ₁₀ are adjacent to base station 1 ₆ ; base stations 1 ₁₀ , 1 ₁₁ , 1 ₂₀ are adjacent to base station 1 ₁₅ ; base stations 1 ₉ , 1 ₁₀ , 1 ₁₉ are adjacent to the base station 1 _14. ) Then, from each base station 1 (from the base stations 1 ₆ , 1 ₁₅ , 1 ₁₄ ), the service radio signals containing information about the measured power values are emitted. At each of these neighboring base stations 1 (for example, at base station 1 ₁₀ ), these service radio signals are received and the power of the emitted information radio signals is adjusted according to the measured values of the power of information radio signals received at base stations 1, which are adjacent to the specified neighboring base station 1 (1 base stations which are adjacent to said adjacent base stations 1 ₁₀ are base stations 1 ₆ 1 ₁₅ 1 ₁₄₎ and emitted from the base camp uu 1 (from the base station 1 _10).

где Р_{изм.пр. мин} - минимальное значение мощности из соответствующих измеренных значений мощности информационных радиосигналов; Р'_{q изл} - значение мощности излучаемых информационных радиосигналов, которое устанавливают на базовой станции 1 в процессе регулировки по результатам измерений; К_зап > 1 - коэффициент, определяющий запас по чувствительности и диапазон регулировки мощности излучаемых информационных радиосигналов.The power control of the radiated information radio signals at each of these neighboring base stations 1 is carried out, for example, according to the minimum power value from the measured power values of the information radio signals received at the base stations 1, which are adjacent to the specified neighboring base station 1, and radiated from this base station 1 using the formula

where P _{rev. min} - the minimum power value from the corresponding measured power values of the information radio signals; R _{'q rad} - power value information of the emitted radio signals, which is mounted on the base 1 in the process of adjusting measurements; To _zap > 1 - coefficient determining the margin of sensitivity and the range of adjustment of the power of the emitted information radio signals.

При временном разделении информационных и служебных каналов радиосвязи на каждой базовой станции 1 для излучения служебных радиосигналов используют заданные рабочие частоты радиосигналов. При этом излучение информационных и служебных радиосигналов осуществляют в различные моменты времени.Formula (3) shows that at each base station 1, in the process of adjusting the power of the radiated information radio signals, it is necessary to set such a power value P ' _{q rad} , at which the equality P _{meas. min} = P _{av min} At the same time, the power of the emitted information radio signals is adjusted when the condition

When temporarily separating the information and service radio channels at each base station 1, the specified operating frequencies of the radio signals are used to emit the service radio signals. In this case, the radiation of information and service radio signals is carried out at various points in time.

где R - радиус зон 3 действия базовых станций 1; с - скорость света в вакууме.Timing diagrams of sequential transmission of informational radio signals in all directions from the base station 1 ₁₉ , which is the source of the transmitted information, to the boundaries of the served territory are conventionally shown in Fig.3. Here IS1, IS2, IS3 are informational radio signals; SS - service radio signals; T is the duration of the information radio signals; τ is the time interval separating the time points of the start of the emission of information radio signals from neighboring base stations 1. Neglecting the propagation time of information radio signals in the transceiver paths of the equipment located at base stations 1, the value of τ is determined by the formula

where R is the radius of the zones 3 of the action of base stations 1; c is the speed of light in vacuum.

 Thus, due to the fact that the placement of base stations 1, in contrast to the prototype, is carried out not in the centers of conditional cells, which are equal regular hexagons that densely cover the served territory, but at the vertices of these regular hexagons, and the radii of zones 3 of action of all base stations 1 are equal to the length of the sides of each regular hexagon, the distance between any two adjacent base stations 1 is equal to the radii of the zones 3 of their action. In this regard, for the transmission of information signals from the base station 1, which is the source of the transmitted information, to the base stations 1, in the zones 3 of which there are movable objects 2, the method does not require the use of a switching center and fiber-optic communication lines connecting the switching center to base stations 1, which greatly simplifies the method. However, in the process of transmitting informational radio signals from the base station 1, which is the source of the transmitted information, to the base stations 1, in the zones 3 of which there are movable objects 2, the radiation of informational radio signals is carried out from all base stations 1 located on the served territory, due to which the method does not require determination of base stations 1, in the zones of action 3 of which are moving objects 2, which greatly simplifies the method. In addition, due to the significant overlap of zones 3 of the activity of neighboring base stations 1, the method allows to reduce, compared with the prototype, the number of operating frequencies of information radio signals received at moving objects 2 from seven to five, which also simplifies the method. Along with this, due to the rational placement of base stations 1 in the served territory, the method allows the reception of these information radio signals from each base station 1 to receive these information radio signals at neighboring base stations 1, measure their power and adjust at each base station 1 the power of the emitted information radio signals according to the measured values, which significantly improves the quality of information reception on moving objects 2 when changing the radii of zones 3 of the action of base stations 1, o the agreed changes in the radio propagation conditions.

 A system for implementing the method is presented in figure 4. The system contains transceivers 4, one each of which is included in each of the base stations 1, and radio receivers 5, placed one at a time on each of the moving objects 2, located within the service area. Figure 4 shows, as an example, a system containing twelve transceivers 4 and three radios 5. In this case, a description of the system and the operation of this system when implementing the method is given for an arbitrary number of transceivers 4, one each of base stations 1, and radio receivers 5, placed one at a time on each of the movable objects 2 located within the boundaries of the served territory.

 Base stations 1 are located at the vertices of the conditional cells, which are equal regular hexagons, densely spaced among themselves, densely covering the served territory. The radius of the zone 3 of action of each base station 1 is set equal to the length of the side of each regular hexagon. At each point of the served territory, at least two zones 3 of activity of neighboring base stations 1 overlap.

 The transmission frequency of the base station 1 is the corresponding operating frequency of the radio signals emitted from this base station 1. The receiving frequency of the radio 5 is the corresponding operating frequency of the information radio signals received at the corresponding moving object 2.

The terms “transmission frequency” and “reception frequency” of a device are generally accepted. (See, for example, Gromakov, Yu.A. Standards and systems for mobile radio communications. - M.: Eco-Trends, 2000, p.22.)
Of the six preset different operating frequencies at each base station 1, the transmission frequency of this base station 1 is set, which is different from the preset transmission frequencies of neighboring base stations 1. Of these six preset operating frequencies at each moving object 2, five different reception frequencies of the radio receiver 5, located on this moving object 2.

 All elements and blocks that make up the system for implementing the method are known and described in the literature.

 The transceiver 4 included in each base station 1 shown in FIG. 5, contains a first receiving antenna 6, three channels for receiving radio signals, each of which contains a first bandpass filter 7, a first low-noise amplifier 8, a first amplitude limiter 9, a first frequency detector 10, a first squaring unit 11, a first integrator 12, a first analog -digital converter (ADC) 13. The transceiver 4 also contains an electronic switch 14, a controlled generator 15, an adjustable power amplifier 16, a transmitting antenna 17, a first microcontroller 18, a task unit 19.

 The output of the first receiving antenna 6, designed for non-directional reception of information and service radio signals emitted from neighboring base stations 1, is connected to the inputs of all the first bandpass filters 7. Information and service radio signals are high-frequency frequency-manipulated electromagnetic oscillations of the corresponding identical operating frequencies. In this regard, at equal speeds of information transmission, the values of the bandwidth of information and service radio signals can be considered equal. The first band-pass filters 7 are used to select radio signals in frequency. Moreover, each of them is tuned to a predetermined transmission frequency of one of the respective neighboring base stations 1. The bandwidth of each first band-pass filter 7 is not less than the bandwidth of the radio signals of the corresponding operating frequency. The passbands of the first bandpass filters 7 are non-overlapping. In each channel for receiving radio signals, the output of the first band-pass filter 7 is connected to the input of the first low-noise amplifier 8, designed to amplify the received radio signals. The output of the first low-noise amplifier 8 is connected to the input of the first amplitude limiter 9, which serves to eliminate spurious amplitude modulation of signals arising from the propagation of radio waves. The output of the first amplitude limiter 9 is connected to the input of the first frequency detector 10, intended for the frequency detection of received radio signals. The output of the first low-noise amplifier 8 is also connected to the input of the first squaring block 11, the output of which is connected to the input of the first integrator 12. The first squaring block 11 and the first integrator 12 are connected in series to generate signals proportional to the power of the received radio signals. The output of the first integrator 12 is connected to the input of the first ADC 13. The outputs of all the first ADCs 13 are connected to the corresponding inputs of the first microcontroller 18. The first microcontroller 18 is used to control the electronic switch 14, to form modulating binary sequences of pulses corresponding to service information transmitted to neighboring base stations 1, for adjusting the gain in power of the adjustable power amplifier 16, as well as for forming in the transceiver 4 contained in the bases station 1, which is a source of transmitted information modulating a binary sequence of pulses, corresponding information transmitted to moving objects 2. The outputs of all first frequency detectors 10 are connected to the corresponding switched inputs of the electronic switch 14, as well as to the corresponding inputs of the first microcontroller 18. The outputs of the first microcontroller 18 are connected to one of the switched inputs and to the control inputs of the electronic switch 14, as well as to the control input of an adjustable amplifier eating 16 power. The output of the electronic switch 14 is connected to the control input of the controlled generator 15, tuned to a given transmission frequency of this base station 1. The controlled generator 15 is used to generate high-frequency frequency-manipulated signals corresponding to the transmitted information, and high-frequency frequency-manipulated signals corresponding to the service information transmitted to neighboring base stations 1. The output of the controlled generator 15 is connected to the input of an adjustable power amplifier 16, to the output of which connected to the transmitting antenna 17, designed for non-directional radiation into the space of information and service radio signals. The outputs of the task unit 19 are connected to the inputs of the first microcontroller 18, which at the base station 1, which is the source of the transmitted information, serves to enter information into the first microcontroller 18, intended for transmission to mobile objects 2, and at each of all other base stations 1, for setting the values of the operating frequencies of the information radio signals received at this base station 1, at which from this base station 1 carry out the emission of information radio signals at a given operating frequency.

 The term "controlled generator" is generally accepted. (See, for example. Theoretical Foundations of Radar. Edited by V.E. Dulevich. - M.: Soviet Radio, 1978, p. 358). The frequency of oscillations generated by the controlled generator is determined by the voltage acting on its control input. In this case, the controlled generator is a voltage controlled generator. Voltage controlled oscillators are known and described in the literature devices. (See, for example, Horowitz P., Hill. W. The Art of Circuit Engineering. In 3 volumes: T. 1. Transl. From English. - 4th ed. Revised and enlarged. - M.: Mir, 1993 , p. 308.) By the tuning frequency of a controlled generator we mean the center frequency of the operating range of the controlled generator corresponding to the operating range of control voltages.

As the unit 19 of the task can be used any known and described in the literature digital data input device. (See, for example, Shevkoplyas B.V. Microprocessor structures. Engineering solutions. - M .: Radio and communications, 1993, p. 27.)
All base stations 1 contain the same type of transceivers 4, differing only in frequency values, which are tuned to the first band-pass filters 7 and controlled oscillators 15.

 A radio receiver 5, located on each movable object 2, shown in Fig.6, contains a second receiving antenna 20, five channels for receiving radio signals, each of which contains a second bandpass filter 21, a second low-noise amplifier 22, a second amplitude limiter 23, a second frequency detector 24 , the second squaring unit 25, the second integrator 26, the second ADC 27. The radio receiver 5 also contains a second microcontroller 28, an indicator 29.

 The output of the second receiving antenna 20, designed for non-directional reception of informational radio signals emitted from base stations 1, is connected to the inputs of all second bandpass filters 21, which serve to select informational radio signals by frequency. Each of them is tuned, respectively, to one of the given reception frequencies of this radio 5. The bandwidth of each second band-pass filter 21 is not less than the bandwidth of the information radio signals of the corresponding operating frequency. The passbands of the second bandpass filters 21 are non-overlapping. In each channel for receiving radio signals, the output of the second band-pass filter 21 is connected to the input of the second low-noise amplifier 22, designed to amplify the received information radio signals. The output of the second low-noise amplifier 22 is connected to the input of the second amplitude limiter 23, which serves to eliminate spurious amplitude modulation of signals arising from the propagation of radio waves. The output of the second amplitude limiter 23 is connected to the input of the second frequency detector 24, intended for the frequency detection of received information radio signals. The output of the second low-noise amplifier 22 is also connected to the input of the second squaring unit 25, the output of which is connected to the input of the second integrator 26. The second squaring unit 25 and the second integrator 26 are connected in series to generate signals proportional to the power of the received radio signals. The output of the second integrator 26 is connected to the input of the second ADC 27. The outputs of all the second frequency detectors 24 and the outputs of all the second ADCs 27 are connected to the corresponding inputs of the second microcontroller 28, designed to process the information received from base stations 1 and display it on the indicator 29, the inputs of which are connected to the outputs of the second microcontroller 28.

As the first amplitude limiters 9 and second amplitude limiters 23, for example, nonlinear resonant amplifiers tuned to the corresponding operating frequencies can be used. (See, for example, Gonorovsky I. S. Radio engineering circuits and signals. - M .: Radio and communications, 1986, p. 235.)
On all moving objects 2 are placed the same type of radio receivers 5, and the operating frequencies, which are tuned to the second band-pass filters 21, can coincide on different moving objects 2.

At base stations 1 and on mobile objects 2, respectively, such values of the amplification factors of the first low-noise amplifiers 8 and second low-noise amplifiers 22 are set, at which the sensitivity of the radio signal receiving channels at base stations 1 and at mobile objects 2 is equal to P _min . At base stations 1, depending on the specified values of the operating frequencies f _{q of the} information radio signals emitted from these base stations 1, initially such values of power gains of adjustable power amplifiers 16 are set (during operation of the system, these values can be changed) at which the power of the information radio signals emitted from these base stations 1 are, respectively, P _{q ex} . In this case, the values of P _{q izl} and the value of P _av.min are selected based on a given value of the radius of the zone 3 of action of each base station 1, equal to the length of the side of each of these regular hexagons.

 Information and service radio signals are narrowband; the propagation time of radio signals from each base station 1 to neighboring base stations 1 and the time interval for measuring the power of the received radio signals are negligible compared to the duration of any of the pulses of modulating binary pulse sequences corresponding to information transmitted to moving objects 2, as well as service information; the propagation time of signals in the transceiver paths of base stations 1 is negligible.

 Accepted assumptions correspond, for example, to the following system parameters. The radius of zone 3 of action of each base station 1 is 500 m; the working frequencies of the radio signals emitted from all base stations 1 are respectively 12, 13, 14, 15, 16 and 17 MHz; the duration of any of the pulses of modulating binary sequences of pulses corresponding to information transmitted to moving objects 2, as well as service information, not less than 10 ms, the time interval of a single measurement of the power of the received radio signals is not more than 0.1 ms.

 Consider the implementation of the method using the system shown in figure 4.

 At the base station 1, which is the source of the transmitted information, in the block 19 of the job transceiver 4, shown in figure 5, enter information intended for transmission to moving objects 2.

 At each base station 1, in addition to the base station 1, which is the source of the transmitted information, the operating frequencies of the information radio signals received at this base station 1 are entered into the transceiver 4 setting unit 19, at which the information radio signals are emitted from this base station 1 at a given working frequency.

 The system operates alternately in two modes: the "Information transfer to moving objects 2" mode (main mode) and the "Adjustment of radiation power of base stations 1" mode (service mode).

 At each base station 1, the first microcontroller 18 sets the transceiver 4 into the mode of "Transmission of information to moving objects 2".

 At the base station 1, which is the source of the transmitted information, the first microcontroller 18 reads in binary code from the task unit 19 information intended for transmission to movable objects 2. Then, the first microcontroller 18 generates a resulting binary code containing a binary code corresponding to information transmitted to the mobile objects 2, and a binary code attached to it containing a sign of the end of the information radio signal. The first microcontroller 18 generates a binary sequence of pulses corresponding to the resulting binary code, which is fed to one of the switched inputs of the electronic switch 14. At the same time, the first microcontroller 18 generates control signals on the control inputs of the electronic switch 14, through which the electronic switch 14 connects the specified switched input to the control input controlled generator 15. A controlled generator 15, tuned to a given transmission frequency of this base station 1, according the signals acting at the output of the electronic switch 14, produces a high-frequency frequency-manipulated signal, which is fed to the input of an adjustable power amplifier 16. The transmitting antenna 17 emits into the space the thus generated informational radio signal corresponding to the information transmitted to the moving objects 2. The emitted informational radio signal ends with a sequence of radio pulses containing the sign of the end of the informational radio signal.

 The reception of the information radio signal emitted from the base station 1, which is the source of the transmitted information, is carried out at all neighboring base stations 1 using the transceivers 4 contained therein. The first receiving antenna 6, which is part of each of these transceivers 4, receives the information radio signal, radiated from the base station 1, which is the source of the transmitted information. The received information radio signal is fed to the inputs of the first band-pass filters 7. At each base station 1, which is adjacent to the base station 1, which is the source of the transmitted information, at the output of one of the first band-pass filters 7, tuned to a given operating frequency of the information radio signals emitted from the base station 1, which is the source of the transmitted information, the corresponding high-frequency frequency-manipulated signal corresponding to the received information radio signal. This signal is fed to the input of the first low-noise amplifier 8, from the output of which the signal is fed to the input of the first amplitude limiter 9. The first amplitude limiter 9 carries out the amplitude limitation of the signal. From the output of the first amplitude limiter 9, the signal is fed to the input of the first frequency detector 10. The first frequency detector 10 carries out frequency detection of the received information radio signal and generates a binary sequence of pulses corresponding to the transmitted information, which are received at the corresponding switched input of the electronic switch 14 and at the input of the first microcontroller 18 .

где К_зап = 1.2, и в случае его выполнения принимает решение о наличии на входе приемопередатчика 4 информационного радиосигнала соответствующей рабочей частоты, в противном случае первый микроконтроллер 18 принимает противоположное решение. (Коэффициент К_зап = 1.2 обеспечивает запас по чувствительности, необходимый для измерения мощности принимаемых информационных радиосигналов при ухудшении условий распространения радиоволн и недостаточный для приема радиосигналов с удаленных базовых станций 1. ) Затем первый микроконтроллер 18 считывает из блока 19 задания заданные значения рабочих частот информационных радиосигналов, принимаемых на этой базовой станции 1, при которых с этой базовой станции 1 осуществляют излучение информационных радиосигналов на заданной рабочей частоте, и определяет по этим заданным значениям рабочих частот и значениям сигналов, действующих на выходах соответствующих первых АЦП 13, рабочую частоту информационного радиосигнала максимальной мощности. (На каждой базовой станции 1, являющейся соседней по отношению к базовой станции 1, являющейся источником передаваемой информации, определяемая таким образом рабочая частота информационного радиосигнала максимальной мощности является рабочей частотой информационных радиосигналов, излучаемых с базовой станции 1, являющейся источником передаваемой информации.) Первый микроконтроллер 18 формирует управляющие сигналы на управляющих входах электронного коммутатора 14, по которым электронный коммутатор 14 подключает выход первого частотного детектора 10, соответствующего рабочей частоте информационного радиосигнала максимальной мощности, к управляющему входу управляемого генератора 15. Управляемый генератор 15 формирует высокочастотный частотно-манипулированный сигнал на заданной рабочей частоте, который поступает на вход регулируемого усилителя 16 мощности. С выхода регулируемого усилителя 16 мощности усиленный по мощности сигнал поступает на вход передающей антенны 17, которая излучает в пространство информационный радиосигнал, соответствующий информации, передаваемой на подвижные объекты 2. Излучаемый информационный радиосигнал также оканчивается последовательностью радиоимпульсов, содержащей признак окончания информационного радиосигнала.At the same time, the signal from the output of the indicated first low-noise amplifier 8 is fed to the input of the first squaring unit 11, the output signal of which is fed to the input of the first integrator 12, which, at the input of the first ADC 13, generates a signal proportional to the power of the received information radio signal in accordance with formula (2) . The digital code from the outputs of the specified first ADC 13 is supplied to the inputs of the first microcontroller 18. The first microcontroller 18 determines by the digital code acting on the output of the specified first ADC 13 and the known value of the gain of the corresponding channel for receiving radio signals the power value of the received information radio signal R _pr The first microcontroller 18 checks the condition

where K _app = 1.2, and in case of its implementation, it makes a decision on the presence of an informational radio signal of the corresponding operating frequency at the input of the transceiver 4, otherwise the first microcontroller 18 takes the opposite decision. (The coefficient K _app = 1.2 provides a margin of sensitivity necessary for measuring the power of received information radio signals when the propagation conditions of the radio waves deteriorate and insufficient for receiving radio signals from remote base stations 1.) Then, the first microcontroller 18 reads from the set unit 19 the set values of the operating frequencies of the information radio signals received at this base station 1, in which from this base station 1 carry out the emission of information radio signals at a given operating frequency e, and determines from these predetermined values of the operating frequencies and the values of the signals acting on the outputs of the corresponding first ADCs 13, the operating frequency of the information radio signal of maximum power. (At each base station 1, which is adjacent to the base station 1, which is the source of the transmitted information, the operating frequency of the maximum power information radio signal thus determined is the operating frequency of the information radio signals emitted from the base station 1, which is the source of the transmitted information.) The first microcontroller 18 generates control signals at the control inputs of the electronic switch 14, through which the electronic switch 14 connects the output of the first frequency about the detector 10, corresponding to the operating frequency of the information signal of maximum power, to the control input of the controlled generator 15. The controlled generator 15 generates a high-frequency frequency-manipulated signal at a given working frequency, which is input to an adjustable power amplifier 16. From the output of the adjustable power amplifier 16, a power-amplified signal is fed to the input of a transmitting antenna 17, which emits into the space an informational radio signal corresponding to information transmitted to moving objects 2. The emitted informational radio signal also ends with a sequence of radio pulses containing a sign of the end of the informational radio signal.

 The reception of information radio signals emitted from these neighboring base stations 1 is carried out at all other neighboring base stations 1, which are adjacent to the indicated neighboring base stations 1, using the transceivers 4 contained therein. Moreover, the first receiving antenna 6, which is part of of each of these transceivers 4, receives informational radio signals emitted from these neighboring base stations 1. Received informational radio signals arrive at the inputs of the first band-pass filters 7, cat rye performed their selection frequency. At each base station 1, which is adjacent to the indicated neighboring base stations 1, at the output of the first bandpass filters 7, high-frequency frequency-manipulated signals corresponding to the received information radio signals act. These signals are fed to the inputs of the first low-noise amplifiers 8, from the outputs of which the signals are fed to the inputs of the first amplitude limiters 9. The first amplitude limiters 9 carry out the amplitude limitation of the signals. From the outputs of the first amplitude limiters 9, the signals are fed to the inputs of the first frequency detectors 10. The first frequency detectors 10 perform frequency detection of the received information radio signals and generate binary sequences of pulses corresponding to the transmitted information, which are transmitted to the switched inputs of the electronic switch 14 and to the inputs of the first microcontroller 18.

где К_зап = 1.2, и в случае его выполнения принимает решение о наличии на входе приемопередатчика 4 информационного радиосигнала соответствующей рабочей частоты, в противном случае первый микроконтроллер 18 принимает противоположное решение. Затем первый микроконтроллер 18 считывает из блока 19 задания заданные значения рабочих частот информационных радиосигналов, принимаемых на этой базовой станции 1, при которых с этой базовой станции 1 осуществляют излучение информационных радиосигналов на заданной рабочей частоте, и определяет по этим заданным значениям рабочих частот и значениям сигналов, действующих на выходах соответствующих первых АЦП 13, рабочую частоту информационного радиосигнала максимальной мощности. Первый микроконтроллер 18 формирует управляющие сигналы на управляющих входах электронного коммутатора 14, по которым электронный коммутатор 14 подключает выход первого частотного детектора 10, соответствующего рабочей частоте информационного радиосигнала максимальной мощности, к управляющему входу управляемого генератора 15. Управляемый генератор 15 формирует высокочастотный частотно-манипулированный сигнал на заданной рабочей частоте, который поступает на вход регулируемого усилителя 16 мощности. С выхода регулируемого усилителя 16 мощности усиленный по мощности сигнал поступает на вход передающей антенны 17, которая излучает в пространство информационный радиосигнал, соответствующий информации, передаваемой на подвижные объекты 2. Излучаемый информационный радиосигнал также оканчивается последовательностью радиоимпульсов, содержащей признак окончания информационного радиосигнала.At the same time, the signals from the outputs of the first low-noise amplifiers 8 are fed to the inputs of the first squaring blocks 11, the output signals of which are fed to the inputs of the first integrators 12, which, at the inputs of the first ADCs 13, generate signals proportional to the power of the received information radio signals in accordance with formula (2). Digital codes from the outputs of the first ADCs 13 are supplied to the inputs of the first microcontroller 18. The first microcontroller 18 determines by the digital codes acting on the outputs of the first ADCs 13 and the known values of the gain of the corresponding channels for receiving radio signals, the power values P _{pr of the} received information radio signals. For each of the channels for receiving radio signals, the first microcontroller 18 checks the condition

where K _app = 1.2, and in case of its implementation, it makes a decision on the presence of an informational radio signal of the corresponding operating frequency at the input of the transceiver 4, otherwise the first microcontroller 18 takes the opposite decision. Then, the first microcontroller 18 reads from the set unit 19 the set values of the operating frequencies of the information radio signals received at this base station 1, at which the information radio signals are emitted from this base station 1 at a given operating frequency, and determines from these set values of the operating frequencies and signal values operating at the outputs of the respective first ADCs 13, the operating frequency of the information radio signal of maximum power. The first microcontroller 18 generates control signals at the control inputs of the electronic switch 14, through which the electronic switch 14 connects the output of the first frequency detector 10, corresponding to the working frequency of the maximum power information radio signal, to the control input of the controlled generator 15. The controlled generator 15 generates a high-frequency frequency-manipulated signal on a given operating frequency, which is input to an adjustable power amplifier 16. From the output of the adjustable power amplifier 16, a power-amplified signal is fed to the input of a transmitting antenna 17, which emits into the space an informational radio signal corresponding to information transmitted to moving objects 2. The emitted informational radio signal also ends with a sequence of radio pulses containing a sign of the end of the informational radio signal.

 By analogy with the above, the transceivers 4, which are part of all other base stations 1, operate in the "Information transfer to mobile objects 2" mode.

 The information radio signals emitted from each base station 1 penetrate through the first receiving antennas 6 to the inputs of the transceivers 4 included in the neighboring base stations 1. However, this does not cause a loop of the system, since the radiation of information radio signals from each base station 1, except the base station 1, which is the source of the transmitted information, is carried out only when receiving at this base station 1 information radio signals of one of the operating frequencies set at this base station 1. In this case, the radiation of information radio signals from the base station 1, which is the source of the transmitted information, is carried out regardless of the operation of neighboring base stations 1.

 With a sufficiently high speed of the described elements and blocks, we can assume that the transceivers 4, which are part of the base stations 1, simultaneously receive information radio signals emitted from neighboring base stations 1 and emit them at the corresponding given operating frequencies.

 At each base station 1, the first microcontroller 18 also reads the signals from the outputs of all the first ADCs 13 and stores the values of the power of information radio signals received at these base stations 1 in the "Information transfer to mobile objects 2" mode. The number of these base stations 1 includes the base station 1, which is the source of the transmitted information, since at this base station 1 the radio information signals emitted from neighboring base stations 1 are also received and their power is measured.

 Thus, the transceivers 4 included in the base stations 1, in accordance with the information contained in the blocks 19 of the task, sequentially, in all directions from the base station 1, which is the source of the transmitted information, to the boundaries of the served territory at all other subsequent base stations 1 adjacent to the previous base stations 1, simultaneously receive the information radio signals emitted from the previous base stations 1 and emit them on the respective preset slaves other frequencies.

At each mobile object 2 located within the service area, the second receiving antenna 20, which is part of the radio receiver 5 shown in FIG. 6, is received by the radio information signals emitted from base stations 1, in the zones of action 3 of which this mobile object 2. These signals from the output of the second receiving antenna 20 are fed to the inputs of the second bandpass filters 21, which select them in frequency. The signals from the outputs of the second bandpass filters 21 are fed to the inputs of the second low-noise amplifiers 22, the signals from the outputs of which are fed to the inputs of the second amplitude limiters 23. The second amplitude limiters 23 carry out the amplitude limitation of the signals. From the outputs of the second amplitude limiters 23, the signals are fed to the inputs of the second frequency detectors 24, which carry out frequency detection of the received information radio signals. At the same time, the signals from the outputs of the second low-noise amplifiers 22 are fed to the inputs of the second squaring units 25, the output signals of which are fed to the inputs of the second integrators 26, which at the inputs of the second ADCs 27 form signals in accordance with formula (2) proportional to the power of the received information radio signals. Digital codes from the outputs of the second ADCs 27 are fed to the inputs of the second microcontroller 28. The second microcontroller 28 determines by the digital codes acting on the outputs of the second ADCs 27 and the known values of the gain of the corresponding channels for receiving radio signals the power values P _{pr of the} received information radio signals. For each of the channels of the second radio reception microcontroller 28 checks the condition P _ave ≥R _pr.min and if it decides to perform a stock inlet 5, a radio frequency information corresponding working radio signal, otherwise a second microcontroller 28 receives the opposite decision. (If the propagation conditions of the radio waves deteriorate, the decrease in the power of the received information radio signals is compensated by an increase in the power of the information radio signals emitted from the base stations 1, which is carried out in the "Adjusting the radiation power of the base stations 1" mode.) Then, the second microcontroller 28 processes the binary pulse sequences acting on the outputs of the corresponding second frequency detectors 24, and generates at the inputs of the indicator 29 signals along which the indicator 29 displays information, transmitting movable objects 2.

 Mode "Adjusting the radiation power of base stations 1". At the end of the radiation of the next informational radio signal at the base station 1, which is the source of the transmitted information, the first microcontroller 18 sets the transceiver 4 into the "Adjustment of the radiation power of base stations 1" mode. In this case, the first microcontroller 18 generates a binary sequence of pulses on one of the switched inputs of the electronic switch 14, containing service information about the measured and stored during the previous mode "Information Transfer to Moving Objects 2" power of received information radio signals. At the same time, the first microcontroller 18 generates control signals at the control inputs of the electronic switch 14, by which the electronic switch 14 connects the specified switched input to the control input of the controlled generator 15. The thus generated binary binary pulse sequence is fed to the control input of the controlled generator 15, which forms the corresponding high-frequency -manipulated signal supplied to the input of an adjustable power amplifier 16, from the output of which of the amplified power signal is input to the transmitting antenna 17. The transmitting antenna 17 emits into space service radio signal containing information on the measured values of the power information radio signals received at the base station 1, which is the source of information transmitted.

 At each of the base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, at the end of the reception of the next informational radio signal, the first microcontroller 18 leads (as a result of identification by the first microcontroller 18 of a sequence of radio pulses containing the termination of the informational radio signal) transceiver 4 in mode "Adjusting the radiation power of base stations 1". In this case, the first microcontroller 18 generates control signals at the control inputs of the electronic switch 14, by which the electronic switch 14 disconnects the outputs of the first frequency detectors 10 from the input of the controlled generator 15. To the input of the last electronic switch 14 connects one of the outputs of the first microcontroller 18, which forms on it a binary sequence of pulses containing service information about the values measured and stored during the previous mode "Information transfer to moving objects 2" yach power received information radio signals. The service binary pulse sequence thus formed is fed to the control input of the controlled oscillator 15, which generates a corresponding high-frequency frequency-manipulated signal fed to the input of an adjustable power amplifier 16, from the output of which a power-amplified signal is supplied to the input of the transmitting antenna 17. Transmitting antenna 17 of each from base stations 1, which are adjacent to base station 1, which is a source of transmitted information, radiates into space service radio signal containing information about the measured power values of the information radio signals received at each of these neighboring base stations 1.

где К_зап = 1.2. На каждой из указанных соседних базовых станций 1 первый микроконтроллер 18 сравнивает между собой измеренные значения мощности информационных радиосигналов, принимаемых на базовых станциях 1, являющихся соседними по отношению к указанной соседней базовой станции 1, и излучаемых с этой базовой станции 1 (с базовой станции 1, которая содержит приемопередатчик 4, в состав которого входит указанный первый микроконтроллер 18), и определяет среди них минимальное значение мощности Р_{изм.пр. мин}. (Регистрация информационных радиосигналов происходит при выполнении условия

где К_зап = 1.2, следовательно, значение

и отлично от нуля.) Затем первый микроконтроллер 18 определяет с помощью формулы (3) требуемое значение мощности Р'_{q изл} излучаемых информационных радиосигналов и формирует на управляющем входе регулируемого усилителя 16 мощности управляющий сигнал, в соответствии с которым мощность излучаемых информационных радиосигналов принимает значение Р'_{q изл}.At the same time, at each of these neighboring base stations 1, the first receiving antenna 6 receives radio service signals emitted from base stations 1 that are adjacent to the indicated neighboring base stations 1. Received radio signals arrive at the inputs of the first band-pass filters 7, which select them by frequency. The signals from the outputs of the first band-pass filters 7 are fed to the inputs of the first low-noise amplifiers 8. From the outputs of the first low-noise amplifiers 8, the signals are fed to the inputs of the first amplitude limiters 9, which realize the amplitude limitation of the signals. From the outputs of the first amplitude limiters 9, the signals are fed to the inputs of the first frequency detectors 10, which carry out frequency detection of the received service radio signals and generate binary pulse sequences containing information about the measured power values of the information radio signals received at base stations 1, which are adjacent to these neighboring base stations 1 (among base stations 1 that are adjacent to said neighboring base stations 1, have tsya and the base station 1, which is a source of information to be transmitted). These binary sequences of pulses are fed to the inputs of the first microcontroller 18. Similarly to the above, the first microcontroller 18 makes a decision about the presence or absence at the input of the transceiver 4 of the service radio signals of the corresponding operating frequencies by comparing the values of their power with a threshold value

where K _app = 1.2. At each of these neighboring base stations 1, the first microcontroller 18 compares with each other the measured power values of the information radio signals received at base stations 1, which are adjacent to the indicated neighboring base station 1, and emitted from this base station 1 (from base station 1, which contains a transceiver 4, which includes the specified first microcontroller 18), and determines among them the minimum value of power P _{meas. min} (Registration of informational radio signals occurs when the condition

where K _app = 1.2, therefore, the value

and nonzero.) Then, the first microcontroller 18 determines by the formula (3) the desired power value P _{'q rad} emitted information radio signals and generates in the adjustable amplifier 16 power control input a control signal in accordance with which the power radiated information radio signals assumes the value P ' _{q ex} .

 By analogy with the above, the transceivers 4 included in the base stations 1 that are not adjacent to the base station 1, which is the source of the transmitted information, operate in the "Adjusting the radiation power of base stations 1" mode.

 By analogy with the "Information transfer to mobile objects 2" mode described above in the "Adjusting the radiation power of base stations 1" mode, radios 5 located on mobile objects 2 receive radio service signals emitted from base stations 1, in the zones 3 of which they are located . In this case, in each radio 5, the second microcontroller 28, based on the analysis of the received service radio signals, blocks the display of service information on the indicator 29.

 The mode "Adjusting the radiation power of base stations 1" has a fixed and the same duration at all base stations 1. At each base station 1, at the end of the "Adjustment of the radiation power of base stations 1" mode, the first microcontroller 18, when transmitting other informational radio signals to mobile objects 2, returns the transceiver 4 to the "Information transfer to mobile objects 2" mode.

 Thus, when transmitting information to mobile objects 2 located within the service area, the described method does not require, unlike the prototype, the use of a switching center and fiber-optic communication lines connecting the switching center to base stations 1, which greatly simplifies the method. However, the method allows, in contrast to the prototype, to transmit information to moving objects 2 without defining base stations 1, in the zones 3 of which they are located, which greatly simplifies the method. In addition, the method allows to reduce, compared with the prototype, the number of operating frequencies of information radio signals received at moving objects 2, from seven to five on each moving object 2, which also simplifies the method. Along with this, due to the rational placement of base stations 1 on the served territory, the method can significantly improve the quality of information reception on mobile objects 2 when changing the radii of zones 3 of the action of base stations 1, due to changes in the propagation conditions of radio waves.
