Abstract

FIELD: mobile radio communication. SUBSTANCE: procedure of information transmission to mobile objects consists in arrangement of base stations with coverage zones equal in length to leg of each regular hexagon in centers of ideal cells presenting equal regular hexagons which tightly cover serviced territory. Seven different working frequencies of information radio signals emitted by all these base stations are specified and stabilized. One working frequency of information radio signals emitted by this base station is selected from seven specified working frequencies. Each mobile object located within limits of serviced territory sets working frequencies of information radio signals received by this mobile object. Information signals corresponding to information transmitted to mobile objects located within limits of serviced territory are transmitted from 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 transmitted information are emitted to mobile objects located in coverage zones of these base stations, these information radio signals are received on specified working frequencies. Base stations with coverage zones equal to length of leg of each regular hexagon are positioned in addition in vertexes of specified regular hexagons. Seven different working frequencies of information radio signals emitted by all these base stations coinciding with seven specified working frequencies of information radio signals emitted by all base stations positioned in centers of regular hexagons are set and stabilized. One working frequency of information radio signals emitted by this base station is selected from seven specified working frequencies by each base station positioned in vertex of regular hexagon. Working frequency different from specified working frequencies of information radio signals emitted by adjacent base stations is specified for each base station as working frequency of information radio signals emitted by this base station. Base station which is source of transmitted information is one of base stations positioned in centers and vertexes of regular hexagons, base stations in which coverage zones mobile objects are located are base stations positioned in centers and vertexes of regular hexagons. Five different working frequencies out of specified seven frequencies are working frequencies of information radio signals received by this mobile object and specified for each mobile object. 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 from 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. All base stations which are adjacent to base station which is source of transmitted information simultaneously receive information radio signals emitted by last base station and emit them on corresponding specified working frequencies. After that all other base stations which are adjacent to specified base stations simultaneously receive information radio signals from specified base stations and emit them on corresponding specified working frequencies. Thereupon simultaneous reception of information radio signals emitted by previous base stations and their emission on corresponding specified working frequencies are carried out 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. Information radio signals are emitted on specified working frequency by each base station except base station which is source of transmitted information and are received by this base station on one working frequency specified for this base station. Each base station except base station which is source of transmitted information stabilizes specified working frequency of emitted information radio signals on working frequency of one information radio signal received by this base station on which this base station emits information radio signals. EFFECT: simplified procedure based on rational positioning of base stations on serviced territory and formation of reference high-stability oscillations on base station which is source of transmitted information. 7 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 a personal radio call system (see, for example, Gromakov Yu.A. Standards and mobile radio communication systems. - M .: Eco-Trends, 2000, pp. 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 information transmitted to mobile objects located within the served territory are emitted from this radio transmitting station, on the decree OF DATA 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 D. B. Zimin. - M .: Radio and communications, 2000, p.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 x stations and received at mobile objects within the service area, out of seven settable operating frequencies at each base station, one working frequency of informational radio signals emitted from this base station is set, different from the settable operating frequencies of informational radio signals emitted from neighboring base stations, moreover, at each base station, the preset operating frequency of the emitted information radio signals is stabilized by the frequency of the highly stable reference oscillations generated at of the base station, information optical signals corresponding to information transmitted to mobile objects located within the served territory are transmitted from one of the base stations, which is the source of the transmitted information, through the fiber-optic communication line to the switching center, base stations are determined in the switching center, in the areas of operation of which are moving objects, then information optical signals corresponding to the transmitted information are transmitted from the switching center via fiber optic lines pits due to these base stations, these base stations to perform radio radiation information corresponding to the transmitted information on moving objects located in areas of these base stations, the reception of information carried on the radio signals corresponding defined 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. Moreover, the method provides for the stabilization of the preset operating frequencies of the information radio signals emitted from base stations, which improves the quality of information reception at moving objects.

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.

 For the same reason, the method does not allow at each base station to stabilize the specified operating frequency of the emitted information radio signals according to the operating frequencies of information radio signals received from neighboring base stations and stabilized as a result of the frequency of the highly stable reference oscillations generated at the base station, which is the source of the transmitted information, and requires the formation of highly stable reference oscillations at each base station, which also 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 propagate only in one of seven specified operating frequencies, and therefore receive informational radio signals in each of the moving objects when moving around the serviced territory, it is necessary to carry out at all seven preset operating frequencies, which also complicates the method.

 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 Communication, Ed. By D. B. Zimin, Moscow: Radio and Communications, 2000, p.

 The technical task to be solved is the simplification of the method based on the rational placement of base stations in the served territory and the formation of highly stable reference oscillations only at the base station, which is the source of the transmitted information.

 The solution to the technical problem in the method of transmitting information to moving objects, namely, in the centers of conditional cells, which are equal regular hexagons, densely covering the served territory, base stations with radiuses of action zones equal to the length of the sides of each regular hexagon are set and stabilized seven different operating frequencies of the information radio signals emitted from all these base stations, of the seven set operating frequencies at each of these base stations I set one operating frequency of the information radio signals emitted from this base station, at each of the moving objects located within the service area, sets the working frequencies of the information radio signals received at this mobile object, information signals corresponding to the information transmitted to the moving objects within of the served territory, transmit from the base station, which is the source of the transmitted information, to the base stations, in the areas of which there are mobile objects from these base stations emit information radio signals corresponding to the transmitted information on mobile objects located in the zones of operation of these base stations, receive information radio signals at specified operating frequencies, achieved by the fact that additional base stations are placed at the vertices of the indicated regular hexagons with the radii of the action zones equal to the length of the side of each regular hexagon define and stabilize seven different operating frequencies of information ion radio signals emitted from all these base stations that coincide with the seven preset operating frequencies of the information radio signals emitted from all base stations located in the centers of regular hexagons, out of seven set working frequencies at each of the base stations located at the vertices of regular hexagons, one the working frequency of the information radio signals emitted from this base station, set at each base station by the working frequency of the information radio signals emitted from of that base station, is the operating frequency different from the set operating frequencies of information radio signals emitted from neighboring base stations, the base station that is the source of the transmitted information is one of the base stations located in the centers and at the vertices of regular hexagons, base stations, in zones the actions of which are moving objects, are the base stations located in the centers and at the vertices of regular hexagons, in the areas of action of which there are moving objects, setting the working frequencies of the information radio signals received at each mobile object at this mobile object are five different of the seven preset working frequencies, the information signals corresponding to the information transmitted to mobile objects located within the served territory are the corresponding information radio signals, the transmission of these information of radio signals from the base station, which is the source of the transmitted information, to base stations, in the areas of which there are mobile objects, consists in the fact that from the base station, which is the source of transmitted information, they carry out the emission of information radio signals at a given operating frequency, at all base stations that are adjacent to the base station, which is the source of transmitted information, they simultaneously receive the last base station of informational radio signals and their radiation at the corresponding preset operating frequencies, then at all other base stations, which are in relation to the indicated base stations, they simultaneously receive information radio signals emitted from the indicated base stations and emit them at the corresponding preset operating frequencies, then in the same manner sequentially, in all directions from the base station, which is the source of the transmitted information, to the boundaries of the served territory on all other subsequent base stations that are adjacent to previous base stations, simultaneously receive radiated from of the leading base stations of informational radio signals and their emission at the respective preset operating frequencies, while from each base station, except the base station, which is the source of the transmitted information, the emission of informational radio signals at the preset operating frequency is carried out when one of the preset radio signals is received at this base station this base station operating frequencies, at each base station, except the base station, which is the source of the transmitted information, stabilization the set working frequency of the emitted information radio signals is carried out at the working frequency of one of the information radio signals received at this base station, at which the information radio signals are emitted from this base station at the set working frequency.

 The term "moving object" is generally accepted (see, for example, Soloviev, Yu. A. Satellite Navigation Systems. - M.: Eco-Trends, 2000, p. 47). To moving 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 depicts 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 information radio signals emitted from each of these base stations, for the case in which the number base stations is seventy-two; 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 information radio signals emitted from each of these base stations, as well as with the 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 seventy-two, the number of mobile objects p Avno 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 one radio transmitter is a part of the base station that is the source of the transmitted information, the number of transceivers included one each of the base stations that are not the sources of the transmitted information is eighteen, and the number of radio receivers, placed one on each of the moving objects, is equal to three, and moving objects in figure 4 are not shown.

 In FIG. 5 shows a radio transmitter included in the base station, which is the source of the transmitted information, and the base station, which is the source of the transmitted information, is not shown in FIG.

 In Fig.6 shows a transceiver that is part of each of the base stations that are not sources of transmitted information, and a base station that is not a source of transmitted information is not shown in Fig.6.

 In FIG. 7 shows a radio receiver located on each of the moving objects, and the moving object in FIG. 7 is not shown.

 In the present description, the following notation is used.

1 _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 operating frequency of the information 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, in the centers and at the tops of the conditional cells, which are equal regular hexagons, densely covering the served territory, base stations 1 are placed (as shown in Fig. 1) (base stations 1 ₁ -1 _{19 19} and base stations 1 ₂₀ -1 ₇₃ respectively) with the radii of the 3 action zones 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 six base stations 1 are adjacent to each base station 1.

 With this arrangement of base stations 1 on the served territory, no more than six 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.

Thus under the zone 3 acts in the emission of radio signals from each base station 1 to recognize an area, within which at the omnidirectional radiation with the base station 1, the radio power P _{q rad} at the operating frequency f _q capacity of these radio signals at their omnidirectional reception at other base stations 1 and on moving objects 2 not less than a certain threshold value P _av.min , which characterizes the sensitivity of the channels for receiving radio signals at base stations 1 and on moving objects 2. Under the zone 3 of the action when receiving radio signals at each base station 1 are aware of the area within which when 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 same P values _min .

где с - скорость света в вакууме.In this regard, assuming that the propagation of radio waves occurs in free space, and the served territory 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 at moving objects 2 is a circle centered at the location of this base station 1 and the 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 in the centers and at the tops of conditional cells, which are equal regular hexagons that densely cover 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 points of placement of neighboring base stations 1. In Fig. 1, the boundaries of the zones 3 of action of base stations 1 are shown conditionally by circles.

Задают и стабилизируют семь различных рабочих частот (Q=7) информационных радиосигналов, излучаемых со всех базовых станций 1. Из семи задаваемых рабочих частот на каждой базовой станции 1 задают, как показано на фиг. 1, одну рабочую частоту информационных радиосигналов, излучаемых с этой базовой станции 1, отличную от задаваемых рабочих частот информационных радиосигналов, излучаемых с соседних базовых станций 1. Таким образом, на базовых станциях 1, не являющихся соседними, задают повторяющиеся рабочие частоты информационных радиосигналов, излучаемых с этих базовых станций 1.In the present description, the term "signal power" means 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. M. Trakhtman. Introduction to the generalized spectral theory of signals . - M .: Soviet Radio, 1972, p.14)

Seven different operating frequencies (Q = 7) are set and stabilized for the information radio signals emitted from all base stations 1. Of the seven set operating frequencies at each base station 1, they are set, as shown in FIG. 1, one operating frequency of information radio signals emitted from this base station 1, different from the set operating frequencies of information radio signals emitted from neighboring base stations 1. Thus, at base stations 1 that are not adjacent, the repeating operating frequencies of information radio signals emitted from these base stations 1.

 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 band of the information radio signals. Moreover, the frequency bands of information 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. At the same time, 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 preset operating frequencies. Then, at all other base stations 1, which are adjacent to the indicated base stations 1, information radio signals emitted from the indicated base stations 1 are simultaneously received and emitted at the corresponding preset 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, simultaneously receive signals transmitted from the previous base stations 1 information radio signals and their radiation at the corresponding specified 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 mobile 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 information radio signals are emitted from this base station 1 ignals at a given 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 _{3 is} carried out when receiving at this base station 1 ₂₉ information radio signals of one of the operating frequencies f ₄ and f specified at the base station 1 _{29 6} , which are the working frequencies of the information radio signals emitted from base stations 1 ₆ and 1 _33, respectively. Moreover, from the base station 1 _{10 the} radiation 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 ₁₀ is a source of transmitted information.

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

The transmission of information radio signals from the base station 1 ₁₀ , which is the source of the transmitted information, to the base stations 1, in the zones 3 of which there are moving objects 2, as shown in figure 2, is as follows. From the base station 1 ₁₀ , 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 ₃₈ , 1 ₄₄ , 1 ₅₀ , 1 ₅₅ , 1 ₄₉ , 1 ₄₃ ), which are adjacent to the base station 1 ₁₀ , which is the source of the transmitted information, they simultaneously receive the radiated from the last base station 1 information radio signals and their radiation at the corresponding specified operating frequencies. Then, at all other base stations 1 (base stations 1 ₅ , 1 ₃₃ , 1 ₆ , 1 ₃₉ , 1 ₁₁ , 1 ₅₆ , 1 ₁₅ , 1 ₆₀ , 1 ₁₄ , 1 ₅₄ , 1 ₉ , 1 ₃₇ ), which are adjacent in in relation to the indicated base stations 1 (base stations 1 ₃₈ , 1 ₄₄ , 1 ₅₀ , 1 ₅₅ , 1 ₄₉ , 1 ₄₃ ), simultaneously receive information radio signals emitted from the indicated base stations 1 and their radiation at the respective preset operating frequencies. Then, in the same way, sequentially, in all directions from the base station 1 ₁₀ , which is the source of the transmitted information, to the boundaries of the served territory at all other subsequent base stations 1 (first, at the base stations 1 ₂ , 1 ₂₉ , 1 ₃₄ , 1 ₇ , 1 ₄₅ , 1 ₅₁ , 1 ₁₆ , 1 ₆₁ , 1 ₆₅ , 1 ₁₈ , 1 ₆₄ , 1 ₅₉ , 1 ₁₃ , 1 ₄₈ , 1 ₄₂ , l ₄ , 1 ₃₂ , 1 ₂₈ , then at the base stations 1 ₂₁ , 1 ₂₅ , 1 ₃ , 1 ₃₀ , 1 ₃₅ , 1 ₄₀ , 1 ₁₂ , 1 ₅₇ , 1 ₆₂ , 1 ₆₆ , 1 ₁₉ , 1 ₆₉ , 1 ₇₂ , 1 ₆₈ , 1 ₁₇ , 1 ₆₃ , 1 ₅₈ , 1 ₅₃ , 1 ₈ , 1 ₃₆ , 1 ₃₁ , 1 ₂₇ , 1 ₁ , 1 ₂₄ and, finally, at base stations 1 ₂₂ , 1 ₂₆ , 1 ₄₆ , 1 ₅₂ , 1 ₇₀ , l ₇₃ , 1 ₇₁ , 1 ₆₇ , 1 ₄₇ , 1 ₄₁ , 1 ₂₃ , 1 ₂₀ ), which are adjacent to the previous base stations 1, simultaneously receive the information radio signals emitted from the previous base stations 1 and their radiation at the respective preset operating frequencies.

 The circuits shown in FIG. 1 and FIG. 2 are examples of placing base stations 1 in a served area, with radiuses of action zones 3 equal to the length of the sides of each regular hexagon, and setting at each base station 1 the operating frequency of information radio signals emitted from of this base station 1, as well as the tasks at each base station 1, except for 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, for which base card 1 perform station information radio radiation at the reference operating frequency.

Timing diagrams of the sequential transmission of information radio signals in all directions from the base station 1 ₁₀ , 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; T is the duration of the information radio signals; τ is the time interval separating the time moments 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 τ = R / c,
where R is the radius of the zones 3 of the action of base stations 1; c is the speed of light in vacuum.

With the indicated placement parameters for the base stations 1 on the served territory with the specified radii of action zones 3, at least three action zones of neighboring base stations 1 overlap at each point of the served territory since the informational radio signals from neighboring base stations 1 are emitted at different operating frequencies, each the receiving point receives informational radio signals of at least three different preset operating frequencies. (So, for example, as shown in figure 1, the moving object 2 ₁ is located in zones 3 of the three base stations 1 ₅ , 1 ₂₈ , 1 ₃₃ , from which the radiation of information radio signals is carried out at operating frequencies f ₅ , f ₁ , f ₆ respectively). Therefore, to ensure guaranteed reception of informational radio signals on moving objects 2 when moving within the service area, it is sufficient to receive informational radio signals on each moving object 2 only at five different out of seven specified operating frequencies.

 Mobile objects 2 receive informational radio signals emitted from base stations 1, in the zones of action 3 of which these mobile objects 2 are located. At the same time, informational radio signals are received on mobile objects 2 at preset operating frequencies, which are five different on each mobile object 2 from seven set working 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 three zones 3 of the activity of neighboring base stations 1. Thus, for example, the boundary of the served territory shown in Fig. 1 can be a closed polygonal line passing through all the extreme base stations 1 (base stations 1 ₂₀ , 1 ₂₄ , 1 ₂₁ , 1 ₂₅ , 1 ₂₂ , 1 ₂₆ , 1 ₃₀ , 1 ₃₅ , 1 ₄₀ , 1 ₄₆ , 1 ₅₂ , 1 ₅₇ , 1 ₆₂ , 1 ₆₆ , 1 ₇₀ , 1 ₇₃ , 1 ₆₉ , 1 ₇₂ , 1 ₆₈ , 1 ₇₁ , 1 ₆₇ , 1 ₆₃ , 1 ₅₈ , 1 ₅₃ , 1 ₄₇ , 1 ₄₁ , 1 ₃₆ , 1 _{3 1} , 1 ₂₇ , 1 ₂₃ ).

 At each base station 1, except for the base station 1, which is the source of the transmitted information, stabilization of the set operating frequency of the emitted information radio signals is stabilized by the operating frequency of one 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 the set operating frequency. Set at each base station 1, except for 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, at which the information radio signals are emitted from this base station 1 at a given operating frequency, allow the transmission of information radio signals from base station 1, which is the source of the transmitted information, to base stations 1, in the zones of action 3 of which are moving objects 2, and therefore, and all other base station 1 without "loops". Therefore, stabilization of the operating frequency of the information radio signals emitted from each base station 1, except for the base station 1, which is the source of the transmitted information, is carried out as a result of the working frequency of the information radio signals emitted from the base station 1, which is the source of the transmitted information. The stabilization of the operating frequency of the information radio signals emitted from the base station 1, which is the source of the transmitted information, is carried out, for example, by the frequency of the highly stable reference oscillations generated at this base station 1.

The only preset at base stations 1 ₃₈ , 1 ₄₄ , 1 ₅₀ , 1 ₅₅ , 1 ₄₉ , 1 ₄₃ operating frequency of information radio signals received at these base stations 1, at which from these base stations 1 carry out the emission of information radio signals at specified working frequencies, is, as shown in figure 2, the operating frequency of the information radio signals emitted from the base station 1 ₁₀ , which is the source of the transmitted information. At base stations 1 ₅ , 1 ₃₃ , 1 ₆ , 1 ₃₉ , 1 ₁₁ , 1 ₅₆ , 1 ₁₅ , 1 ₆₀ , 1 ₁₄ , 1 ₅₄ , 1 ₉ , 1 ₃₇ indicated by the specified operating frequencies are the corresponding operating frequencies of the information radio signals emitted from base stations 1 ₃₈ , 1 ₄₄ , 1 ₅₀ , 1 ₅₅ , 1 ₄₉ , 1 ₄₃ , etc. Stabilization of the operating frequencies of information radio signals emitted from base stations 1 ₃₈ , 1 ₄₄ , 1 ₅₀ , 1 ₅₅ , 1 ₄₉ , 1 ₄₃ is carried out as a result of the operating frequency of information radio signals emitted from base station 1 ₁₀ , which is a source of transmitted information. Stabilization of the working frequencies of information radio signals emitted from base stations 1 ₅ , 1 ₃₃ , 1 ₆ , 1 ₃₉ , 1 ₁₁ , 1 ₅₆ , 1 ₁₅ , 1 ₆₀ , 1 ₁₄ , 1 ₅₄ , 1 ₉ , 1 ₃₇ , which are adjacent in relation to the indicated base stations 1 ₃₈ , 1 ₄₄ , 1 ₅₀ , 1 ₅₅ , 1 ₄₉ , 1 ₄₃ , carry out the operating frequencies of the information radio signals emitted from the last base stations 1 ₃₈ , 1 ₄₄ , 1 ₅₀ , 1 ₅₅ , 1 ₄₉ , 1 ₄₃ , etc. The stabilization of the operating frequency of the information radio signals emitted from the base station 1 ₁₀ , which is the source of the transmitted information, is carried out by the frequency of the highly stable reference oscillations generated at this base station 1 ₁₀ .

 Thus, due to the fact that the placement of base stations 1, in contrast to the prototype, is carried out not only in the centers of conditional cells, which are equal regular hexagons that densely cover the served territory, but also at the vertices of these regular hexagons, and the radii of the zones of action 3 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. For the same reason, the method allows at each base station 1 to stabilize the set operating frequency of the emitted information radio signals according to the operating frequencies of the information radio signals received from neighboring base stations 1 and stabilized as a result of the frequency of the highly stable reference oscillations generated at the base station 1, which is the source of the transmitted information, and does not require the formation of highly stable reference oscillations at each base station 1, which also 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 the 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.

 A system for implementing the method is presented in figure 4. The system contains a radio transmitter 4, which is part of the base station 1, which is the source of the transmitted information, transceivers 5, which are one each of the base stations 1, which are not sources of the transmitted information, radio receivers 6, placed one on each of the moving objects 2, located within the service area. Figure 4 shows, as an example, a system comprising one radio transmitter 4, eighteen transceivers 5 and three radio receivers 6. Moreover, a description of the system and operation of this system when implementing the method is given for an arbitrary number of transceivers 5, one each of which is a base station 1, which are not sources of transmitted information, and radios 6, placed one at a time on each of the movable objects 2, located within the boundaries of the served territory.

 All base stations 1 are located in the centers and 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 three zones 3 of action of neighboring base stations 1 overlap.

 The transmission frequency of the base station 1 is the corresponding operating frequency of the information radio signals emitted from this base station 1. The receiving frequency of the radio receiver 6 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 mobile radio communication systems. - M .: Eko-Trends, 2000, p.22).

 Out of the seven 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 the neighboring base stations 1. Of these seven preset operating frequencies on each moving object 2, five different reception frequencies of the radio receiver 6, 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 output of the first receiving antenna 13, designed for non-directional reception of informational radio signals emitted from neighboring base stations 1, is connected to the inputs of all the first bandpass filters 14. The first bandpass filters 14 are used to select informational radio signals by 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 14 is not less than the bandwidth of information radio signals of the corresponding operating frequency. The passbands of the first bandpass filters 14 are non-overlapping. In each channel for receiving informational radio signals, the output of the first band-pass filter 14 is connected to the input of the first low-noise amplifier 15, intended to amplify the received informational radio signals. The output of the first low-noise amplifier 15 is connected to the input of the amplitude limiter 16, designed to isolate the carrier wave of the amplitude-modulated information radio signals. The output of the first low-noise amplifier 15 is also connected to the input of the first amplitude detector 17, which serves for the amplitude detection of the received information radio signals.

The output of the second amplitude modulator 27 is connected to the input of the second power amplifier 28, which serves to amplify the power signals. A second transmitting antenna 29 is connected to the output of the second power amplifier 28. The outputs of the second task unit 31 are connected to the inputs of the second microcontroller 30, which serves to set at each base station 1, except the base station 1, which is the source of the transmitted information, the operating frequency of the information radio signals, radiated from this base station 1, as well as the values of the operating frequencies of the information radio signals received at this base station 1, at which information is transmitted from this base station 1 radio signals at a given operating frequency. The outputs of the second microcontroller 30 are connected to the control inputs of the first electronic switch 21, the second electronic switch 22, the first frequency divider 25 and the second frequency divider 26.

 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 circuitry. In 3 volumes: T.1. Transl. From English - 4th ed. revised and add. - Moscow: Mir, 1993, p. 308).

 As the amplitude limiters 16 can be applied, for example, narrow-band nonlinear resonant amplifiers tuned to the corresponding operating frequencies (see, for example, Gonorovsky IS Radio engineering circuits and signals. - M .: Radio and communication, 1986, p.235 )

 As the first task unit 11 and the second task unit 31, digital input devices known and described in the literature can be used (see, for example, Shevkoplyas B.V. Microprocessor structures. Engineering solutions. - M.: Radio and Communication, 1993, p.27).

 The first frequency divider 25 and the second frequency divider 26 are known and described in the literature devices (see, for example, Horowitz P., Hill W. The art of circuitry. In 3 volumes: T.2. Transl. From English. - 4- e ed. revised and enlarged - M .: Mir, 1993, p.270).

 All base stations 1, which are not sources of transmitted information, contain the same type of transceivers 5, differing only in frequency values, which are tuned to the first band-pass filters 14.

 A radio receiver 6 located on each movable object 2 shown in FIG. 7, contains a second receiving antenna 32, five channels for receiving informational radio signals, each of which contains a second bandpass filter 33, a second low-noise amplifier 34, a second amplitude detector 35, a second squaring unit 36, a second integrator 37, and a second ADC 38. Radio 6 also contains a third microcontroller 39, indicator 40.

 The output of the second receiving antenna 32, designed for non-directional reception of information radio signals emitted from base stations 1, is connected to the inputs of all second band-pass filters 33, which serve to select information radio signals in frequency. Each of them is tuned, respectively, to one of the given reception frequencies of this radio 6. The bandwidth of each second band-pass filter 33 is not less than the bandwidth of the information radio signals of the corresponding operating frequency. The passbands of the second bandpass filters 33 are non-overlapping. In each channel for receiving informational radio signals, the output of the second band-pass filter 33 is connected to the input of the second low-noise amplifier 34, designed to amplify the received informational radio signals. The output of the second low-noise amplifier 34 is connected to the input of the second amplitude detector 35, which serves for the amplitude detection of the received information radio signals. The output of the second low-noise amplifier 34 is also connected to the input of the second squaring unit 36, the output of which is connected to the input of the second integrator 37. The second squaring unit 36 and the second integrator 37 are connected in series to generate signals proportional to the power of the received radio signals. The output of the second integrator 37 is connected to the input of the second ADC 38. The outputs of all the second amplitude detectors 35 and the outputs of all the second ADCs 38 are connected to the corresponding inputs of the third microcontroller 39, designed to process the information received from base stations 1 and display it on the indicator 40, the inputs of which are connected to the outputs of the third microcontroller 39.

 On all moving objects 2 are placed the same type of radio 6, and the operating frequencies, which are tuned to the second band-pass filters 33, can coincide on different moving objects 2.

At all base stations 1, except for base station 1, which is the source of the transmitted information, and at moving objects 2, respectively, such values of the amplification factors of the first low-noise amplifiers 15 and second low-noise amplifiers 34 are set at which the sensitivity of the reception channels of informational radio signals at base stations 1 and at movable objects 2 is equal to R _av.min . At the base station 1, which is the source of the transmitted information, and at other base stations 1, depending on the set values of the operating frequencies f _{q of the} information radio signals emitted from these base stations 1, respectively, such values of the power amplification factors of the first power amplifier 9 and second amplifiers 28 power at which the power values of the information radio signals emitted from these base stations 1 are equal respectively to 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.

 Informational 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; 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 information radio signals emitted from all base stations 1 are respectively 11, 12, 13, 14, 15, 16 and 17 MHz; the duration of any of the pulses of modulating binary sequences of pulses corresponding to the information transmitted to the moving objects 2, at least 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 first block 11 of the job of the radio transmitter 4, presented in figure 5, enter information intended for transmission to moving objects 2. At each base station 1, which is not the source of the transmitted information, in the second block 31 of the task of the transceiver 5, shown in Fig.6, from seven preset values of the operating frequencies enter the preset value of the operating frequency of the information radio signals emitted from this base station 1, different from the preset values the frequency of information radio signals emitted from neighboring base stations 1, as well as the values of the operating frequencies of information radio signals received at this base station 1, at which information radio signals are emitted from this base station 1 at a given operating frequency.

 At the base station 1, which is the source of the transmitted information, the first microcontroller 12 reads from the first job block 11 in binary code information intended for transmission to moving objects 2. Then, the first microcontroller 12 generates a binary pulse sequence corresponding to the information at the low-frequency input of the first amplitude modulator 8 transmitted to moving objects 2. At the same time, at the high-frequency input of the first amplitude modulator 8, highly stable reference oscillations of one of the seven specified operating frequencies generated by the reference generator 7. The first amplitude modulator 8 generates a high-frequency amplitude-modulated signal with a modulation coefficient of M = 0.5. This signal is fed to the input of the first power amplifier 9, from the output of which the amplified signal is fed to the input of the first transmitting antenna 10. The first transmitting antenna 10 emits into the space the thus generated information radio signal corresponding to the information transmitted to the moving objects 2.

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 neighboring base stations 1 using the transceivers 5 contained in them, shown in FIG. 6. In this case, the first receiving antenna 13, which is part of each of these transceivers 5, receives an information radio signal emitted from the base station 1, which is the source of the transmitted information. The received information radio signal is fed to the inputs of all the first band-pass filters 14. 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 14, tuned to the 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 amplitude-modulated signal with a coefficient corresponding to the received information radio signal modulation factor M = 0.5. This signal is input to the first low-noise amplifier 15, the output of which is fed to the input of the amplitude limiter 16, which selects the carrier wave of the received amplitude-modulated information radio signal, and to the input of the first amplitude detector 17, which performs amplitude detection of the received information radio signal. The signal from the output of the amplitude limiter 16 is supplied to the corresponding switched input of the second electronic switch 22 and to the input of the first squaring unit 18. From the output of the first squaring unit 18, the signal is fed to the input of the first integrator 19, which at the input of the first ADC 20 generates a signal in accordance with formula (2) proportional to the power of the received information radio signal. The digital code from the outputs of the specified first ADC 20 is supplied to the inputs of the second microcontroller 30. The second microcontroller 30 determines by the digital code acting at the output of the specified first ADC 20 and the known value of the gain of the corresponding channel for receiving informational radio signals, the power value of the received informational radio signal R _ave . A second microcontroller 30 checks the condition P _ave ≥R _pr.min and if it decides to perform a stock inlet radio transceiver 5 of the information corresponding to the operating frequency, otherwise a second microcontroller 30 receives the opposite decision. Then, the second microcontroller 30 reads from the second block 31 of the job the set value of the operating frequency of the information radio signals emitted from this base station 1, as well as the set values of the operating frequencies of the information radio signals received at this base station 1, at which information is emitted from this base station 1 radio signals at a given operating frequency, and determines from these
preset values of the operating frequencies and the values of the signals acting on the outputs of the respective first ADCs 20, 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.) Second microcontroller 30 generates control signals at the control inputs of the first electronic switch 21, which connects the output of the first amplitude detector 17, co the corresponding operating frequency of the maximum power information radio signal to the low-frequency input of the second amplitude modulator 27. The second microcontroller 30 also generates control signals at the control inputs of the second electronic switch 22, which connects the output of the amplitude limiter 16 corresponding to the working frequency of the maximum power information radio signal to the first phase input detector 23.

где f_макс - рабочая частота информационного радиосигнала максимальной мощности; f_зад - заданная рабочая частота информационных радиосигналов, излучаемых с данной базовой станции 1; К₁ и К₂ - коэффициенты деления первого делителя 25 частоты и второго делителя 26 частоты, где К₁ и К₂ - положительные целые числа.At the same time, the second microcontroller 30 determines the required value of the ratio of the division factors of the first frequency divider 25 and the second frequency divider 26 according to the formula

where f _max is the operating frequency of the information signal of maximum power; f _ass - the specified operating frequency of the information radio signals emitted from this base station 1; K ₁ and K ₂ are the division factors of the first frequency divider 25 and the second frequency divider 26, where K ₁ and K ₂ are positive integers.

 Formula (4) follows from the condition of synchronization of the phase locked loop formed by a phase detector 23 controlled by a generator 24 and the first frequency divider 25 (see, for example, Theoretical Foundations of Radar. Edited by V.E.Dulevich. - M. : Soviet Radio, 1978, p. 358).

The second microcontroller 30 generates control signals at the control inputs of the first frequency divider 25 and the second frequency divider 26, according to which their division coefficients take the values K ₁ and K ₂ satisfying the relation obtained by formula (4). As a result of this, the signals of frequency f _max act on both inputs of the phase detector 23, the controlled oscillator 24 generates frequency oscillations K ₁ f _max , the second frequency divider 26 divides this frequency by K ₂ times and receives oscillations of the given operating frequency f _ass , the stability of which is determined by stability operating frequency information radio signals emitted from the base station 1, which is the source of the transmitted information. The stability of the latter is determined by the stability of the frequency of highly stable oscillations generated at the base station 1, which is the source of the transmitted information, the reference generator 7.

 At various base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, the obtained values of the ratio of the division coefficients of the first frequency divider 25 and the second frequency divider 26 are generally different.

 The signal from the output of the second frequency divider 26 is fed to the high-frequency input of the second amplitude modulator 27, the low-frequency input of which receives a binary sequence of pulses acting at the output of the specified first amplitude detector 17. The second amplitude modulator 27 generates a high-frequency amplitude-modulated signal with a modulation coefficient M = 0.5 . This signal is fed to the input of the second power amplifier 28, from the output of which the amplified signal is fed to the input of the second transmitting antenna 29. The second transmitting antenna 29 emits into the space an informational radio signal thus formed corresponding to the information transmitted to the moving objects 2.

 Thus, at each of the base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, stabilization of the operating frequency of the emitted information radio signals is carried out according to the operating frequency of one of the information radio signals received at this base station 1, at which base station 1 carry out the emission of information radio signals at a given operating frequency. At each of these base stations 1, the indicated operating frequency of one of the received information radio signals is the operating frequency of the information radio signals emitted from the base station 1, which is the source of the transmitted information.

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 these neighboring base stations 1, using the transceivers 5 contained in them, shown in Fig.6. In this case, the first receiving antenna 13, which is part of each of these transceivers 5, receives information radio signals emitted from these neighboring base stations 1. Received information radio signals are received at the inputs of all first bandpass filters 14, which select them by frequency. At each base station 1, which is adjacent to the indicated neighboring base stations 1, at the output of the first bandpass filters 14, high-frequency amplitude-modulated signals corresponding to the received information radio signals operate with a modulation coefficient of M = 0.5. These signals are fed to the inputs of the first low-noise amplifiers 15, from the outputs of which the signals are fed to the inputs of the amplitude limiters 16, which isolate the carrier vibrations of the received amplitude-modulated information radio signals, and to the inputs of the first amplitude detectors 17, which perform amplitude detection of the received information radio signals. The signals from the outputs of the amplitude limiters 16 are fed to the corresponding switched inputs of the second electronic switch 22 and to the inputs of the first squaring blocks 18. From the outputs of the first squaring units 18, the signals are supplied to the inputs of the first integrators 19, which at the inputs of the first ADCs 20 generate signals in accordance with formula (2) that are proportional to the power values of the received information radio signals. Digital codes from the outputs of the first ADCs 20 are supplied to the inputs of the second microcontroller 30. The second microcontroller 30 determines by the digital codes acting on the outputs of the first ADCs 20 and the known values of the gain factors of the respective channels for receiving informational radio signals, the power values P _{pr of the} received informational radio signals. For each of the channels for receiving informational radio signals, the second microcontroller 30 checks the condition P _pr ≥P _prmin and, if it is satisfied, makes a decision on the presence of an informational radio signal of the corresponding operating frequency at the input of the transceiver 5, otherwise the second microcontroller 30 makes the opposite decision. Then, the second microcontroller 30 reads from the second block 31 of the job the set value of the operating frequency of the information radio signals emitted from this base station 1, as well as the set values of the operating frequencies of the information radio signals received at this base station 1, at which information is emitted from this base station 1 radio signals at a given operating frequency, and determines from these given values of operating frequencies and values of signals acting on the outputs of all first ADCs 20, the operating frequency of information onnogo maximum power radio signal. The second microcontroller 30 generates control signals at the control inputs of the first electronic switch 21, which connects the output of the first amplitude detector 17, corresponding to the operating frequency of the maximum power information radio signal, to the low-frequency input of the second amplitude modulator 27. The second microcontroller 30 also generates control signals at the control inputs of the second electronic switch 22, which connects the output of the amplitude limiter 16 corresponding to the operating frequency of the information nnogo radio maximum power to the first input of the phase detector 23.

At the same time, the second microcontroller 30 determines by formula (4) the required value of the ratio of the division coefficients of the first frequency divider 25 and the second frequency divider 26. The second microcontroller 30 generates control signals at the control inputs of the first frequency divider 25 and the second frequency divider 26, according to which their division coefficients take values that satisfy the ratio obtained by formula (4). As a result of this, the oscillations of a predetermined operating frequency f _ass act similarly to that described above at the output of the second frequency divider 26, the stability of which is determined by the stability of the operating frequency of one of the information radio signals emitted from base stations 1 that are adjacent to base station 1, which is the source of the transmitted information .

 The signal from the output of the second frequency divider 26 is fed to the high-frequency input of the second amplitude modulator 27, the low-frequency input of which receives a binary sequence of pulses acting at the output of the specified first amplitude detector 17. The second amplitude modulator 27 generates a high-frequency amplitude-modulated signal with a modulation coefficient M = 0.5 . This signal is fed to the input of the second power amplifier 28, from the output of which the amplified signal is fed to the input of the second transmitting antenna 29. The second transmitting antenna 29 emits into the space an informational radio signal thus formed corresponding to the information transmitted to the moving objects 2.

 Thus, at each of the base stations 1, which are adjacent to the indicated neighboring base stations 1, stabilization of the operating frequency of the emitted information radio signals is carried out according to the operating frequency of one of the information radio signals received at this base station 1, at which from this base station 1 emit information radio signals at a given operating frequency. At each of these base stations 1, the corresponding indicated operating frequency of one of the received information radio signals is the operating frequency of the information radio signals emitted from one of the respective indicated neighboring base stations 1.

 By analogy with the above, all transceivers 5 included in all other base stations 1 function.

 Information radio signals emitted from each base station 1 penetrate through the first receiving antennas 13 to the inputs of transceivers 5 included in 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, it can be considered that the transceivers 5 included in the base stations 1 simultaneously receive information radio signals emitted from neighboring base stations 1 and emit them at the corresponding given operating frequencies.

 Thus, the transceivers 5 included in the base stations 1, in accordance with the information contained in the second task units 31, 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, simultaneously receive the information radio signals emitted from the previous base stations 1 and their radiation to the respective operating frequencies.

 At the same time, at each base station 1, except for the base station 1, which is the source of the transmitted information, stabilization of the specified operating frequencies of the emitted information radio signals is stabilized by the working frequency of one of the information radio signals received at this base station 1, at which radiation is emitted from this base station 1 information radio signals at a given operating frequency.

At each movable object 2 located within the service area, the second receiving antenna 32, which is part of the radio receiver 6 shown in Fig. 7, is received by it receives information radio 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 32 are fed to the inputs of the second band-pass filters 33, which select them in frequency. The signals from the outputs of the second bandpass filters 33 are fed to the inputs of the second low-noise amplifiers 34, the signals from the outputs of which are fed to the inputs of the second amplitude detectors 35, which perform amplitude detection of the received information radio signals. The binary pulse sequences generated by the second amplitude detectors 35 are fed to the inputs of the third microcontroller 39. At the same time, the signals from the outputs of the second low-noise amplifiers 34 are fed to the inputs of the second squaring units 36, the output signals of which are fed to the inputs of the second integrators 37, which are at the inputs of the second ADCs 38 form in accordance with formula (2) the signals proportional to the power of the received information radio signals. Digital codes from the outputs of the second ADC 38 are supplied to the inputs of the third microcontroller 39. The third microcontroller 39 determines by the digital codes acting on the outputs of the second ADC 38 and the known values of the gain factors of the respective channels for receiving informational radio signals, the power values P _{pr of the} received informational radio signals. For each of the channels for receiving informational radio signals, the third microcontroller 39 checks the condition P _pr ≥P _prmin and, if it is satisfied, makes a decision on the presence of the corresponding radio frequency information signal at the input of the radio receiver 6, otherwise the third microcontroller 39 makes the opposite decision. Then the third microcontroller 39 processes the binary sequences of pulses acting on the outputs of the respective second amplitude detectors 35, and generates signals at the inputs of the indicator 40, by which the indicator 40 displays information transmitted to moving objects 2.

 Thus, when transmitting information to moving 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. Moreover, when stabilizing at each base station 1 the specified operating frequency of the emitted information radio signals, the method allows the formation of highly stable reference oscillations only at the base station 1, which is the source of the transmitted information, and does not require, in contrast to the prototype, the formation of the highly stable reference oscillations at each base station 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, in comparison 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.
