Description

The invention relates to communication systems and networks and can be used to create secure communication systems integrated with the Unified telecommunication network, due to the possibility of reconfiguration, taking into account the analysis and forecasting of the used ESE telecommunication resource under external destructive influences, as well as the nature of changes in the operating environment .

Interpretation of terms used in the application.

A communication system is understood as an organizational and technical association of communication facilities deployed in accordance with the tasks being solved and the adopted management system for the exchange of all types of messages (information) between points (communication centers), control bodies and objects (Ermishyan A.G. Theoretical basis for building systems of military communications in associations and formations: a Textbook, Part 1. Methodological foundations for the construction of organizational and technical systems of military communications. St. Petersburg: VAS, 2005. - 740 p., p. 74).

The following are considered as elements of a communication system: communication centers, communication channels, communication channels (lines) (Ermishyan A. Theoretical foundations for building military communications systems in associations and formations: A Textbook. Part 1. Methodological foundations for building organizational and technical systems for military communications. St. Petersburg: YOU, 2005 .-- 740 p., P. 1.7. P. 74).

The Unified Telecommunication Network (ESE) is a set of technologically interconnected public telecommunication networks, dedicated networks, technological communication networks connected to the ESE, special-purpose communication networks and other telecommunication networks for transmitting information using electromagnetic systems (V. Lomovitsky, Fundamentals of Construction information transmission systems and networks / Lomovitsky V.V., Mikhailov A.I., Shestak K.V., Schekotikhin V.M. - M.: Hot line - Telecom, 2004. - 382 p., p. 160).

Communication network is a technological system that includes means and communication lines and is intended for telecommunications (Federal Law "On Communications". 07/08/2003. Adopted by the State Duma on June 18, 2003).

Stability - the ability of a communication system to withstand influences and various factors leading to disruption in the functioning of its (communication system) elements (Ermishyan A.G. Theoretical foundations of building military communications systems in associations and formations: A Textbook. Part 1. Methodological foundations of building organizational and technical systems military communications.SPb .: VAS, 2005 .-- 740 p., p. 340).

Timeliness characterizes the ability of communication to ensure the transmission (delivery) of messages or negotiating within specified (established, normative) terms. The main indicators of timeliness are the likelihood that the time of establishing a connection will not exceed the set time and the time of establishing a connection (Ermishyan A.G. Theoretical foundations of building military communications systems in associations and formations: A Textbook. Part 1. Methodological foundations of building organizational and technical systems of military communications. SPb .: YOU, 2005 .-- 740 p.).

Communication services (consumer services) - activities for the reception, processing, storage, transmission, delivery of telecommunications or mail (Federal Law "On Communications". 07/08/2003. Adopted by the State Duma on June 18, 2003).

Reconfiguration of a communication system consists in changing its structure, topology, operating modes (putting redundant channels (lines) and means of communication into operation, restoring damaged and failed communication means, changing transmission frequencies, reception, transmission power, types of signal processing, channel paths ( paths), azimuths of antennas, noise immunity modes, etc.). Fundamentals of building systems and networks for the transfer of information. Textbook for high schools / V.V. Lomovitsky, A.I. Mikhailov, K.V. Shestak, V.M. Schekotikhin; under. ed. V.M. Schekotikhina - M .: Hot line - Telecom, 2005 .-- 382 p.

There is a method of ensuring the stable functioning of a communication system under external destructive influences (RF Patent No. 2405184, published on November 27, 2010 in Bull. No. 33), which ensures the stability of a communication system when destructive influences affect its structural elements due to proactive reconfiguration, the solution to which is accepted on the basis of analysis and processing of the nature of destructive influences.

The method includes collecting data on the destructive effects on a deployed communication system, forming a model, modeling the process of functioning of a communication system under impacts, proactive reconfiguration of a functioning communication system.

The disadvantage of this method is the lack of the ability to account for the service of subscribers of the communication system (taking into account priority categories), which in turn does not allow the rational distribution of existing telecommunication resources and reduces the timeliness of providing the communication system with the required set of telecommunication services.

The closest in technical essence and performed functions analogue (prototype) to the claimed one is a method of ensuring the stability of communication networks under external destructive influences (patent RU No. 2379753, G06F 21/20, G06N 3/02, published on January 20, 2010 in Bull. No. 2), where the values of the destructive effects on the communication lines of a telecommunication network are controlled, at the same time, the performance value of each type of communication line is evaluated, the values of throughput are scaled to its maximum allowable rate for the set communication, and the values of the destructive effect on the maximum value of the destructive effect, at which the performance of the highest-speed communication line as part of the communication network takes zero value, they train artificial neural networks (NS) with radial basis elements using scalable values to approximate the performance dependencies of each kind of line the relationship from the values of the destructive effects, the matrix of synaptic weights of trained neural networks are preserved, in accordance with By the characteristics of a particular communication network, the communication network administrator installs neural networks with radial basic elements according to the number of communication lines included in the communication network, monitors the values of external destructive influences, scales these values, using the focused direct distribution network with a time delay, predict the values of destructive influences, these values are fed to installed neural networks with radial basis elements, at the outputs of which received They predict the throughput values for each communication line. Based on these values, the communication network administrator distributes the network resource between subscribers taking into account their priority categories.

With such a combination of the described actions, an extension of the functional capabilities of the method is achieved, which is expressed in ensuring the timeliness of the provision of information services to subscribers of various categories of a distributed communication network when exposed to external destructive influences.

However, the prototype method has the drawback: low timeliness of providing the communication system subscribers with the required set of telecommunication services, due to the distribution of available telecommunication resources for communication system subscribers based on their priority categories, but without taking into account the intensity of their movement (change of location), individual characteristics of using the provided resource (schedule) and telecommunication services, as well as the possibility of using the ESE resource and its adaptive planning taking into account that changes in the operational environment and the nature of the tasks performed.

The objective of the invention is to provide a method for forming a secure communication system integrated with the Unified Telecommunication Network under external destructive influences, providing enhanced functionality of the prototype method to increase the timeliness of the provision of telecommunication services to subscribers of the communication system, taking into account the intensity of their movement (change of location), individual features use of the provided resource and telecommunication services, adaptability the effective planning of a telecommunication resource based on changes in the operational environment and the nature of the tasks performed to maintain the required stability (security) of the functioning of the communication system under external destructive influences, as well as to increase the reliability of evaluating the results.

The objective of the invention is solved in that the method of forming a secure communication system integrated with the Unified telecommunication network in the conditions of external destructive influences, which consists in setting the necessary initial data, controlling and predicting the values of destructive influences on the communication line, evaluating and predicting the value of the throughput of each kind of communication line, distribute the network resource between subscribers, taking into account their priority category according to the invention, supplemented: form the structure and topology with communication systems integrated with the ESE, determine the necessary methods of linking to the ESE, taking into account the existing number of access points of the ESE and the average time of their functioning, measure and analyze the used resource of the ESE, measure the number, frequency and duration of external destructive influences, while identifying objects exposed exposure, these objects are ranked by degree of significance, measure the degree of damage and the number of damaged objects, predict the state of the ESE resource, taking into account the external of destructive effects, changes in the structure of the communication system, the nature of the movement of subscribers and elements of the communication system, methods of linking to the elements of the ESE, determine the adequacy of the predicted resource of the ESE for a certain period of time, to ensure the required amount of telecommunication resource of the formed communication system, the set of telecommunication services provided and their time provide, use the formed communication system for the intended purpose, measure the intensity of the output of subscribers in St. the types, number and duration of requests, the duration of the telecommunication services provided, determine the possibility of linking them to points, access points of the ESE, carry out adaptive planning of the telecommunication resource, and on the material carrier, execute a rational structure of the communication system integrated with the ESE, taking into account the nature of the change operational conditions, distribute forces and means on the ground that ensure the timely deployment and continuous operation of the communication system, once they work out a sequence of actions to ensure the protection of the communication system from external destructive influences and form a protective resource, execute a set of documents regulating the order and sequence of work on planning and rational reallocation of a telecommunication resource.

Redistribute the telecommunications resource between the subscribers of the communication system, taking into account the requirements for the timely provision of services (timely service) and the nature of the tasks performed.

The listed new set of essential features provides an opportunity to increase the timeliness of providing the communication system subscribers with the required set of telecommunication services.

The analysis made it possible to establish that there are no analogues identical to the features of the claimed method, which indicates the compliance of the claimed method (options) with the condition of patentability “novelty”.

Search results for known solutions in this and related fields of technology in order to identify features that match the distinctive features of the claimed object from the prototype showed that they do not follow explicitly from the prior art. The prior art also did not reveal the popularity of the impact provided by the essential features of the claimed invention, the transformations on the achievement of the specified technical result. Therefore, the claimed invention meets the condition of patentability "inventive step".

The "industrial applicability" of the method is due to the presence of an element base, on the basis of which devices can be made that implement this method with the achievement of the destination specified in the invention.

The claimed method (options) is illustrated by drawings, which show:

figure 1 is a diagram explaining a method of forming a secure communication system integrated with the ESE in the conditions of external destructive influences;

figure 2 is a diagram explaining the order and sequence of measuring the quantity, frequency and duration of external destructive influences;

figure 3 is a diagram explaining the process of implementing adaptive planning of a telecommunication resource.

, количество абонентов по категориям - (F1, F2, F3).A diagram explaining the method of forming a secure communication system integrated with the ESE under external destructive influences is presented in figure 1, where in block 1 the initial data necessary for the formation of the communication system is entered (entered), namely: the number of communication nodes - [2 ... S], the topology of the communication system taking into account integration with the ESE - (A, B, C, D), the number of communication directions taking into account the ESE - [1 ... M), the number of access points of the ESE - [1 ... m], the average operating time of the points ESE access - $$\overline{t_{ij}}$$

, the number of subscribers by category - (F1, F2, F3).

The structural and topological construction of a communication system and its constituent networks involves its presentation by quantitative indicators through the relevant parameters, as well as a description of the composition, configuration, and interconnection of individual elements (Fundamentals of the construction of information transmission systems and networks. Textbook for universities / V.V. Lomovitsky , A.I. Mikhailov, K.V. Shestak, V.M. Shchekotikhin; ed.V.M. Shchekotikhina - M .: Hot line - Telecom, 2005.- 382 p., P. 57).

.In block 2, they form a communication system integrated with the ESE, namely: they form the structure and topology of the communication system, determine the methods of linking to the ESE, taking into account the number of access points - m and the average time of their functioning - $$\overline{t_{ij}}$$

.

Access points for connecting subscribers are usually located on the objects of the public telecommunication network of the ESE. The binding to such an object and the selection of the required number of digital channels and transmission paths is carried out using equipment of the plesiochronous and synchronous digital hierarchy, with the rental of the digital stream n × E1 (n × 2048 kbit / s) and n × 64 kbit / s.

The structural and topological construction of the communication system is carried out taking into account several N groups of elements of the communication system. For each group of elements, the coordinates of the regions of their distribution are generated.

Simulation of the areas of each group is carried out using the expressions:

$$X_{cc}^{\left(N\right)}=X_{cc}^{\left(N-\mathrm{one}\right)}+\cos \beta \left[L_{\min }^{\left(N\right)}+\left(L_{\max }^{\left(N\right)}-L_{\min }^{\left(N\right)}\right)D_{0,\mathrm{one}}\right],\left(\mathrm{one}\right)$$

D _0,1 is a random number distributed over the interval (0,1), which is obtained using a random number sensor.

The structure of the formed communication system can be modeled using simulators of formal mathematical models of communication channels based on the apparatus of system functions (A. Galkin et al. Modeling of communication system channels. - M .: Communication, 1979. - 96 p., P. 40-52).

.In block 3, the used ESE resource is measured and analyzed taking into account the available number of leased channels and digital paths with a given bandwidth (transmission speed - V _per ), the number of access points - m and the average time of their operation - $$\overline{t_{ij}}$$

.

Throughput - the ability of a communication system to provide timely transmission (reception) of specified information flows.

The capacity of a communication system is determined by the need for command and control of troops (forces) to transmit the flow of operational information at the most busy hour, both in the quantity and type of information transmitted (Telecommunication systems and networks: Textbook. Volume 1. Modern technologies / Ed. By Professor V .P. Shuvalova. - M.: “Hot Line”, 2004. - 647 p.).

Requirements for the capacity of communication directions are set by the number of messages (λ) of a certain volume (V) for various types of communication that must be transmitted on each communication direction, taking into account the requirements for timeliness (Telecommunication systems and networks: Training manual. Volume 1. Modern technologies / Under the editorship of Professor V.P. Shuvalov. - M.: "Hot line", 2004. - 647 p.).

In block 4 measure the amount, frequency and duration of external destructive influences.

Under destructive influences are understood: typical remote unauthorized influences, which are: “denial of service”, so-called DOS attacks, address ping, address falsification, etc. (Shangin V.F. “Computer information protection. Effective methods and means. ”- M.: DMK Press, 2008., pp. 28-29).

The order of operation of block 4 is as follows (figure 2).

In block 4.1, the objects of the communication system that are exposed to external destructive influences are determined.

The objects of influence are objects of communication systems, infrastructures, objects of government. Types of technical intelligence are described in the book of Menshakov Yu.K. “Protection of information from intelligence technology.” - M.: Russian State University for the Humanities, 2002., pp. 18-19.

and time intervals $$\Delta t_j^f$$

, the average operating time of the communication system $${\overline{T}}_{f\mathrm{at}n\mathrm{to}}$$

and the average time between external destructive influences $${\overline{T}}_{d\mathrm{at}}$$

.

According to the data obtained, the following is calculated: average reconfiguration time — formula (3), average communication system functioning time — formula (4), average time between external destructive influences — formula (5).

, вычисляют по формуле:Average reconfiguration time $${\overline{T}}_{Re\mathrm{to}}$$

calculated by the formula:

$${\overline{T}}_{Re\mathrm{to}}=\frac{{\displaystyle \sum _{j=\mathrm{one}}^m{t}_j^{Re\mathrm{to}}}}{M},\left(3\right)$$

- интервал времени реконфигурации системы связи после каждого j-го, внешнего деструктивного воздействия;Where $$t_j^{Re\mathrm{to}}$$

- the time interval for reconfiguring the communication system after each j-th, external destructive effect;

M is the number of actions on the communication system.

вычисляют по формуле:The average operating time of the communication system $${\overline{T}}_{f\mathrm{at}n\mathrm{to}}$$

calculated by the formula:

$${\overline{T}}_{f\mathrm{at}n\mathrm{to}}=\frac{{\displaystyle \sum _{j=\mathrm{one}}^m\Delta t_j^f}}{M},\left(\mathrm{four}\right)$$

- интервал времени функционирования системы связи.Where $$\Delta t_j^f$$

- the time interval of the functioning of the communication system.

The average time between external destructive actions is calculated as the average of the measured time intervals between external destructive actions according to the formula:

$${\overline{T}}_{d\mathrm{at}}=\frac{\mathrm{one}}{K}{\displaystyle \sum _{j=\mathrm{one}}^K\Delta t_j^{\mathrm{at}}},\left(5\right)$$

- значения измеренных интервалов времени между воздействиями;Where $$\Delta t_j^{\mathrm{at}}$$

- the values of the measured time intervals between the effects;

K is the number of time intervals between exposures.

In block 4.3, the values of the ranking indicators of the elements of the system (R ₁ ÷ R _n ) are calculated by the formula:

$$R=\raisebox{1ex}{$K_2$}\!\left/ \!\raisebox{-1ex}{$K_{\mathrm{one}}$}\right.,\left(6\right)$$

where K ₁ - coefficient of intensity of exposure, calculated by the formula:

$$K_{\mathrm{one}}=\frac{m_i}{M},\left(7\right)$$

where m _i is the number of actions on the i-th element of the communication system;

M is the total number of actions on the communication system.

K ₂ - idle rate of the elements of the communication system, calculated by the formula:

$$K_2=\mathrm{one}-\frac{{\overline{T}}_{f\mathrm{at}n\mathrm{to}}}{{\overline{T}}_{f\mathrm{at}n\mathrm{to}}+{\overline{T}}_{Re\mathrm{to}}},\left(8\right)$$

- среднее время функционирования элементов системы связи;Where $${\overline{T}}_{f\mathrm{at}n\mathrm{to}}$$

- the average operating time of the elements of the communication system;

- среднее время реконфигурации системы связи. $${\overline{T}}_{Re\mathrm{to}}$$

- average reconfiguration time of the communication system.

After that, the affected elements of the communication system are ranked by the maximum value of the calculated ranking indicator. To do this, select the minimum R _min and maximum R _max values of the ranking indicators of the affected elements of the communication system. Calculate the magnitude of the values of the ranking indicators of the affected elements of the communication system:

$$\Delta R=R_{\max }-R_{\min }\left(9\right)$$

Determine the ranking step:

$$R_{\Delta }=\frac{\Delta R}{Z},\left(10\right)$$

where Z is the number of categories of importance of elements of a communication system, Z = 3.

Ranking ranges are calculated:

$$R_i\le R_{\min }+R_{\Delta }\left(\mathrm{eleven}\right)$$

$$R_{\min }+R_{\Delta }\le R_i\le R_{\min }+2\cdot R_{\Delta }\left(12\right)$$

$$R_i\ge R_{\min }+2\cdot R_{\Delta }\left(13\right)$$

Then, the affected elements of the communication system are classified according to their belonging to a certain category of importance. Compare indicators and ranking ranges. If condition (11) is satisfied, then the third category is assigned to the affected element of the communication system. If condition (12) is fulfilled, then the second category is assigned to the affected element of the communication system. If condition (13) is satisfied, then the first category is assigned to the affected element of the communication system.

In block 4.4 measure the degree of damage and the number of damaged objects (according to the classification by their belonging to a certain category of importance).

Then, in block 5 (Fig. 1), the state of the ESE resource is forecasted taking into account the analysis and evaluation of external destructive effects, a possible change in the structure of the communication system (movement of elements of the communication system, nature of the movement of subscribers) as a result of adverse factors.

Prediction of the state of the communication resource is carried out on the basis of the parameters measured by specialized programs for monitoring parameters transmitted through communication channels and digital paths of telecommunication traffic. Moreover, the technical implementation of the forecasting process is known in the form of technical devices from a wide range of technical literature (Forecasting Workbook / IV Bestuzhev-Lada. - M.: Thought, 1982. - 430 p., Pp. 281-293. Chuev Yu.V., Mikhailov Yu.B. Forecasting in military affairs.M., Military Publishing House, 1975.279 p. C 137-271).

The initial data for calculating the variable coordinates of the elements of the communication network X _ss and Y _ss (subscribers X _ab and Y _ab ) are the motion parameters: the speed of the element of the communication network (speed of movement of the subscriber) - ν; heading angle Θ movement of the element of the communication system (subscriber), or projection of the velocity vector:

$${\nu }_x=\nu \cdot \cos \Theta \left(\mathrm{fourteen}\right)$$

$${\nu }_y=\nu \cdot \sin \Theta \left(\mathrm{fifteen}\right)$$

The calculation of the changing coordinates of the elements of the communication system is carried out according to the following formulas:

$$X_{\mathrm{from}\mathrm{from}}={\nu }_{x}t+X_{\mathrm{from}\mathrm{from}}^{\left(t_0\right)},\left(16\right)$$

$$Y_{\mathrm{from}\mathrm{from}}={\nu }_{y}t+Y_{\mathrm{from}\mathrm{from}}^{\left(t_0\right)},\left(17\right)$$

where t is the travel time of the communication network element;

и $$Y_{сс}^{\left(t_0\right)}$$

- координаты последнего места размещения элемента системы связи. $$X_{\mathrm{from}\mathrm{from}}^{\left(t_0\right)}$$

and $$Y_{\mathrm{from}\mathrm{from}}^{\left(t_0\right)}$$

- coordinates of the last location of the communication system element.

The calculation of variable coordinates for subscribers of a communication system is carried out according to the following formulas:

$$X_{\mathrm{but}b}={\nu }_{x}t+X_{\mathrm{but}b}^{\left(t_0\right)},\left(\mathrm{eighteen}\right)$$

$$Y_{\mathrm{but}b}={\nu }_{y}t+Y_{\mathrm{but}b}^{\left(t_0\right)},\left(19\right)$$

where t ₀ is the start time of the movement of the subscriber;

, $$Y_{аб}^{\left(t_0\right)}$$

- координаты начального местоположения абонента. $$X_{\mathrm{but}b}^{\left(t_0\right)}$$

, $$Y_{\mathrm{but}b}^{\left(t_0\right)}$$

- coordinates of the initial location of the subscriber.

The simulation of the time value of the movement of an element (subscriber) of a communication system from one position to another is carried out according to the formula:

where t _cf is the average value of the time the element (subscriber) of the communication network moves from one position to another.

The procedure for selecting the coordinates of the deployment area of the moved element (subscriber) of the communication system is iterative. The rule for stopping the coordinate selection procedure uses the criterion:

where R _{cri, j} is the territorial separation between the i-th position of the moved element (subscriber) of the communication system and the j-th position of the communication system of other elements (subscribers) interacting with this element (subscriber);

R _max - the maximum possible territorial separation;

t _obsl - time of timely servicing of the subscriber (s);

- требуемое время своевременности обслуживания абонента (абонентов). $$t_{\mathrm{about}b\mathrm{from}l}^{tR}$$

- the required time for timely servicing of the subscriber (s).

In block 6 determine the sufficiency of a predicted ESE resource for a certain time t + Δt, with a view to ensuring the required volume formed telecommunications resource communication system - V _min ≥V _required, the required set of telecommunication N ≥N _{treb usl} and their specific time of - T _{prev. conv} ≤T req _{(rel. ab)} .

Telecommunication services include the services of backbone transport networks and high-speed data transmission networks, data transmission network services, and mobile communication services. These services provide the transfer between subscribers of various types of information (speech, data, video, etc.), pairing between different types of terminal equipment, customer service (Bitner V.I. Rationing of the quality of telecommunication services: Textbook. / Ed. By Professor V.P. Shuvalova, Bitner V.I., Popov G.N .-- M .: Hot line - Telecom, 2004 .-- 312 p., Ill.).

If the predicted ESE resource is insufficient for the stable functioning of the constructed (formed) communication system and timely provision of the communication system subscribers with the required set of telecommunication services, return to block 2, where the formed communication system is reconfigured based on their requirements.

If the ESE resource is sufficient, then go to block 7, where the constructed (formed) communication system is used for its intended purpose (the functioning process).

The intended use of the communication system is carried out taking into account the heterogeneous communication networks included in it. Moreover, the structures of the studied communication networks are considered as sets of {M} bipolar systems. The poles in bipolar systems, in our case, are the subscribers of communication networks. The information direction of communication (subscriber-to-subscriber) will be considered efficient if there is at least one way of successful functioning from one subscriber to another (Simulation of means and complexes of communication and automation. Ivanov EV St. Petersburg: VAS, 1992. - 206 p. 125).

In block 8, the intensity of the subscribers ’communication, the types, quantity and duration of requests, as well as the duration of the services provided is measured, which makes it possible to assess the individual characteristics of the use of the provided telecommunication resource. In addition, they determine the possibility of linking subscribers to points, access points of ESE in specific locations, taking into account the required set of telecommunication services provided and the nature of the tasks performed.

Individual features are assessed by collecting, accumulating and updating statistics on the structure and functioning of the elements of the communication system, their subscribers and the signals and information streams transmitted by them using the control and measuring equipment of technical control (Menshakov Yu.K. Protection of objects and information from technical means intelligence - Moscow: Russian State Humanitarian University, 2002 .-- 399 p., pp. 385-387).

In block 9 shall assess the degree of customer satisfaction provides telecommunication services (QoS) based on (average) time their expectations - t _standby ≤t _{standby. req.} , required transfer rate (bandwidth) - V _per ≥V _{per. Treb} and completeness (range) of services provided - N _conv ≥N _des.

Quality of service - the total effect of service indicators (complex characteristic), which determines the degree of user satisfaction with the services provided. Rationing of the quality of service is carried out for the main service - messaging.

The main criteria for standardizing the quality of telephone service: availability, continuity (connection safety); probability of loss on calls; reliability of switching stations; maximum allowable time intervals for individual stages of establishing connections (Bitner V.I. Rationing of the quality of telecommunication services: Textbook. / Ed. by Professor V.P. Shuvalov, Bitner V.I., Popov G.N. - M .: Hot line - Telecom, 2004 .-- 312 p.).

If subscribers are satisfied with the telecommunication services provided, the process of functioning of the communication system (application of the communication system for its intended purpose) continues. If the subscribers of the communication system are not completely satisfied with the telecommunication services provided, then they proceed to block 10 (Fig. 3), where adaptive planning of the provided resource is carried out.

In block 10.1 (Fig. 3), the rational structure of the communication system integrated with the ESE is executed on a physical medium based on the availability of forces and means, the nature of the tasks performed, the degree of enemy influence, and changes in the operational environment.

In the general case, the planning of the deployment and functioning of the rational structure of the communication system includes a number of material actions on material objects, for example, the development of various documents, diagrams, maps, etc., in which the sequence, methods and time of accomplishing tasks are established; conducting reconnaissance (going to the place of the proposed deployment of elements of the communication system, measuring the dimensions of the platforms for deploying antennas and hardware communications, studying physical and geographical conditions (measuring the depth of crossings), etc.); calculations and development of options for constructing a communication system (P.K. Altukhov, I.A. Afonsky and others. Fundamentals of the theory of command and control of troops. / Under the editorship of Altukhov P.K. - M .: Military Publishing House, 1984. - 221 pp., pp. 17, 137-141. Military Encyclopedic Dictionary. - M.: Onyx 21 Century Publishing House, 2002. - 1432 p., pp. 1104, 1128).

In block 10.2, they distribute forces and assets on the ground that ensure the timely deployment and continuous operation of the formed communications system (P.K. Altukhov, I.A. Afonsky, etc. Fundamentals of the theory of command and control of troops. / Under the editorship of P. Altukhov - M .: Military Publishing, 1984.- 221 p., P. 19, 146-150).

In block 10.3, a sequence of actions is developed to ensure the protection of the communication system from possible predicted external destructive influences (Dudnik B.Ya. Reliability and survivability of a communication system / B.Ya. Dudnik, V.F. Ovcharenko. - M.: Radio and communication, 1984.).

Based on the developed sequence, in block 10.4, the necessary protective resource is formed.

In block 10.5, a set of documents is executed that regulates the order and sequence of work on planning and rational redistributing the available telecommunication resource between subscribers of the communication system (Fundamentals of Control Theory in Military Systems. Part 1. Training manual. EA Karpov, I.V. Kotenko / Edited by A.Yu. Runeev.Spb .: VUS, 2000.- 194 p., Pp. 134, 168).

In block 11, the telecommunications resource is redistributed between the subscribers of the communication system, taking into account the requirements for the timeliness of the services provided (timeliness of service) and the nature of the tasks performed.

Then in block 12 re-evaluate the degree of satisfaction of subscribers with the telecommunication services provided. In case of dissatisfaction of subscribers, they return to block 10, where they again proceed to the process of adaptive planning of a telecommunication resource. If the subscribers are satisfied with the telecommunication services provided, the process of functioning of the communication system (application of the communication system for its intended purpose) continues until the end of the operating time (simulation) - t _m = 0, block 13.

Thus, the claimed method of forming a secure communication system, integrated with the ESE under external destructive influences, improves the timeliness of the provision of telecommunication services to subscribers of the communication system, taking into account the intensity of their movement (change of location), individual characteristics of the use of the provided resource and telecommunication services, the possibility of adaptive planning of a telecommunication resource based on changes in the operational environment and hara a cter of tasks to maintain the required stability (security) of the functioning of the communication system under external destructive influences, as well as to increase the reliability of the assessment of the results, which allows the task of the claimed method to be considered solved.

The assessment of the attainability of the claimed technical result in the method was carried out by comparing the reliability of the assessment of the results obtained by modeling the process of functioning of the communication system for the prototype method and for the proposed method.

We show by calculation the possibility of achieving the formulated technical result.

From Formula 22 (Ventzel E.S., Ovcharov L.A. Probability Theory and its Engineering Applications. - M.: Nauka. Gl. Ed. Phys.-Math. Lite. - 1988, 480 pp., P. 463):

$$P\left(\left|p_{\mathrm{about}w}-p_{\mathrm{about}w}^{*}\right|<\epsilon \right)=2F\left(\frac{\epsilon \sqrt{N}}{\sqrt{p_{\mathrm{about}w}^{*}\cdot \left(\mathrm{one}-p_{\mathrm{about}w}^{*}\right)}}\right),\left(22\right)$$

where Φ is the Laplace function;

N is the number of simulated events;

p _osh - the real value of the assessment;

- требуемое значение оценки; $$p_{\mathrm{about}w}^{*}$$

- the required value of the assessment;

ε is the value of the confidence interval.

We determine the reliability of the simulation results of the functioning of the communication system, taking:

$$D=P\left(\left|p_{\mathrm{about}w}-p_{\mathrm{about}w}^{*}\right|<\epsilon \right)=2F\left(\frac{\epsilon \sqrt{N}}{\sqrt{p_{\mathrm{about}w}^{*}\cdot \left(\mathrm{one}-p_{\mathrm{about}w}^{*}\right)}}\right).\left(23\right)$$

We pass from the Laplace function to its argument (Simulation of means and complexes of communication and automation. Ivanov E.V. SPb .: VAS, 1992. - 206 p., P. 14):

$$t_{\alpha }=\left(\frac{\epsilon \sqrt{N}}{\sqrt{p_{\mathrm{about}w}^{*}\cdot \left(\mathrm{one}-p_{\mathrm{about}w}^{*}\right)}}\right).\left(24\right)$$

This value of the argument of the Laplace function can be represented as follows:

$$t_{\alpha }^2=\frac{{\epsilon }^{2}N}{p_{\mathrm{about}w}^{*}\cdot \left(\mathrm{one}-p_{\mathrm{about}w}^{*}\right)}.\left(25\right)$$

вычислить не удается, можно воспользоваться упрощенной формулой для наихудшего случая $$p_{ош}=p_{ош}^{*}=0,5$$

. Тогда:If p _osh ; $$p_{\mathrm{about}w}^{*}$$

cannot be calculated, you can use the simplified worst-case formula $$p_{\mathrm{about}w}=p_{\mathrm{about}w}^{*}=0,5$$

. Then:

$$t_{\alpha }^2=\mathrm{four}{\epsilon }^{2}N.\left(26\right)$$

и $$t_{\alpha 2}^2$$

$$t_{\alpha 2}=2\cdot 0,05\cdot \sqrt{10}=0,316.\left(28\right)$$

Evaluation of the effectiveness of the claimed method:

$$E=\left|\frac{t_{\alpha \mathrm{one}}-t_{\alpha 2}}{t_{\alpha 2}}\right|\cdot \mathrm{one\; hundred}\%;\left(\mathrm{29th}\right)$$

. $$E=\left|\frac{0,283-0,316}{0,316}\right|\cdot \mathrm{one\; hundred}\approx 10,\mathrm{four}\%$$

.

Thus, the effectiveness of the claimed method in comparison with the method prototype is 10.4%, which is achieved by the claimed technical result.
