Abstract

FIELD: communication.

SUBSTANCE: invention relates to a method for modeling the connection of mobile elements of a corporate management system to a fixed communication network. In the method, the geographical fragment of the territory is set, where the elements of the corporate management system are planned to be located. Local fragments of the territory are excluded, where the elements of the corporate management system cannot be deployed. The number and composition of bodies, the structure of the information directions of the corporate management system, the requirements of the corporate management system for communication services, the time of modeling the process of functioning of the corporate management system, the period of checking the coordinates and operating mode of mobile elements of the corporate management system are set. The composition and structure of the fixed communication network are determined. The communication nodes of the elements of the corporate management system are connected to the fixed communication network. Routing options are generated. The routing option in the specified information directions is selected, taking into account the requirements for communication services. Routes between the information-interconnected subscribers of the corporate management system are formed. The coordinate grid of the geographical fragment of the territory, the requirements of the mobile elements of the corporate management system for the availability of communication services of the fixed network, rules for the movement of mobile elements of the corporate management system, types, characteristics, priority and conditions for the use of communication tools used for the deployment of anchor lines are additionally set. Local fragments of the territory are excluded, where it is impossible to deploy communication lines of a given type. The coordinates and mode of operation of mobile elements of the corporate management system are determined with a given verification period. For each mobile element that arrived at the next place of application, according to the functional purpose, the maximum possible consumption of communication means is determined by deploying direct communication lines with the required characteristics in each information direction. The distance to all communication nodes of the fixed network is estimated relatively to the conditions for the deployment of various types of communication means. For each type of communication lines for each mobile element of the corporate management system, a variation series of communication nodes of the fixed network is built based on the obtained distances. Nodes are excluded from the variation series that cannot be connected due to physical and geographical conditions. The consumption of communication means is estimated, necessary for the deployment of the binding line of the mobile element of the corporate management system to the nearest fixed communication node in accordance with the conditions and priority of the use of communication means. It is compared with the maximum possible consumption of communication means. When exceeding the maximum possible consumption of communication means, direct communication lines are deployed in each information direction and the type and amount of spent communication means is remembered. If the consumption of communication means does not exceed the limit value, then the mobile element of the corporate management system is connected to the nearest communication node of the fixed network. Routes are formed in the specified information directions. The fulfillment of the requirements for communication services are checked in each information direction. The availability coefficient of communication services is calculated as the ratio of the amount of services provided with the required quality to the total number of services required for all subscribers of the mobile element of the corporate management system. If the calculated availability coefficient meets the specified requirements, then the type and number of communication means spent to connect the mobile element of the corporate management system to the fixed communication network is remembered. If the calculated availability coefficient does not meet the specified requirements, then the steps for connecting the mobile element of the corporate management system to the communication nodes of the stationary network are repeated with the following members of the variation series in order, until the specified requirements for the availability of communication services are met at the expense of the total connected communication nodes, or the total cost of communication means for the deployment of anchor lines to the involved fixed network nodes does not exceed the limit value. After the end of the modeling time of the corporate management system operation, the types and number of communication means required for the deployment of anchor lines and direct connections are displayed for each mobile element.

EFFECT: automatization of modeling the connection of mobile elements of a corporate management system to a fixed communication network.

Description

The invention relates to the field of modeling communication networks and can be used in planning dynamically interacting stationary networks and mobile elements of control systems for solving direct and inverse problems of ensuring the availability of telecommunication resources for mobile controls.

In corporate management systems (KSU), tasks may arise, the solution of which requires the presence of mobile points, in which the governing bodies are located for solving particular tasks in a limited, short period of time in a limited area. Examples of such tasks can be the construction of extended facilities (gas and oil pipelines; highways), elimination of the consequences of natural disasters and man-made disasters, resource exploration, expeditions, etc. etc.

The elements of the corporate management system in solving such problems, in conditions of limited resources and time, should rather often move between objects and territories where particular problems are solved. These facilities and territories, as a rule, are equipped with telecommunication infrastructure to varying degrees.

To ensure the effective functioning of the corporate management system as a whole, a timely exchange of information is required between all its stationary and mobile elements. The task of transferring information between the elements of the control system is solved by its communication network. The construction of your own communication network for solving each particular task in remote areas is economically inexpedient and often impracticable in the face of operational tasks, the time for solving which is limited (for example, preventing emergencies and man-made disasters and eliminating their consequences). Therefore, in such control systems, it is advisable to use communication nodes that can be interfaced with public communication networks. These communication centers must provide governing bodies with the entire list of necessary services.

The availability of resources of stationary communication networks for the mobile elements of the corporate control system interfaced with them by nodes is determined by the physical and geographical conditions, the density of telecommunication equipment of the area and the technical capabilities of the stationary network nodes to provide communication services with the required quality. Connecting mobile elements of the KSU to fixed networks requires the deployment of tie lines, the types and number of communication means of which will ensure the required quality of services provided in all information areas.

Communication systems and networks belong to the class of large systems, the design, implementation, operation and evolution stages of which are impossible without the use of various types of modeling (Councils B.Ya., Yakovlev S.A. "Modeling of systems". - M .: Higher school, 2009 , - 343 s).

The factors listed above indicate the need to develop methods for modeling the connection of mobile users to fixed communication networks, taking into account the physical and geographical conditions and telecommunication equipment of the area. The practical need for such methods is determined by the needs of the early determination of the probabilistic-temporal indicators of the availability of resources of public communication networks for corporate control networks in the planned area of their application.

Terms used in the application.

The corporate management system is a set of interdependent and interconnected elements that form a unity, ordered integrity in relation to the object (objects) of management.

Management body - an element of the management system, consisting of officials (subscribers) and having the right to make management decisions within its competence and monitor the implementation of decisions.

The mobile element of the KSU is an element of the control system, a place of functional application for current tasks.

Communication network is a technological system that includes means and communication lines and is intended for telecommunications (Federal Law of July 7, 2003 N 126-FZ "On Communication").

Communication node - a set of technical means of communication that provide traffic (data) routing, provision of communication services and connection of users to the public network.

Communication line - transmission lines, physical circuits and line-cable communication facilities.

A binding line is a temporary communication line designed to connect a mobile element of a KSU to a fixed communication network for the duration of its operation in the area of application.

Information direction - a set of technical means of communication, ensuring the transfer of data between correspondents (subscribers, users).

Routing is the process of determining the route of data transmission in communication networks.

Route - organized according to some rules, the route of an organized data flow through a sequence of elements (nodes and lines) of a communication network.

Communication service is the activity of receiving, processing, storing, transmitting, delivering telecommunication messages or postal items (Federal Law of July 7, 2003 N 126-FZ "On Communication"). Communication services include: telephone communication, data transmission, facsimile communication, video conferencing, provision of confidential connections, formation of virtual connections, etc.

Various methods are known from the prior art for providing fixed network communication services to mobile correspondents.

Thus, there is a known method for modeling a communication network (RF patent No. 2379750, G06F 11/22, publ. 20.01.2010), which makes it possible to simulate the movement of elements of communication networks (nodes and means of communication) and subscribers (users) of communication networks; modeling the features of the physical and geographical conditions of the area where the communication network operates and the subscribers (users) are located; modeling of network topology changes, changing the capacity of communication channels (lines); as well as increasing the adequacy of modeling, taking into account the processes of functioning of a real communication network through the implementation of measurements of the values of indicators of the functioning of a real communication network, modeling the processes of functioning of a simulated communication network, comparing the values of indicators.

The disadvantage of this method is that it does not take into account the influence of the current characteristics of communication nodes of fixed networks, types of anchor lines and direct communication on the spatial availability of services of the required quality.

There is a method for modeling the optimal variant of the topological placement of a set of informationally interconnected subscribers on a given fragment of a public communication network (RF Patent 2690213, IPC G06N 5/00 (2006.01), H04W 16/22 (2009.01), publ. 05/31/2019). The method consists in assigning priorities to informationally interconnected subscribers and ranking them by priority, ranking nodes and communication lines by importance, simulating the initial version of the topological placement of informationally interconnected subscribers, taking into account their priority, the importance of nodes and communication lines, permissible intervals of mutual removal, form a set of routes between informationally interconnected subscribers, taking into account a given structure of information directions, repeating the steps for choosing places for topological placement of informationally interconnected subscribers until the values of the communication quality indicators of each information direction are required, the results are output.

The disadvantage of this method is that it does not take into account the rules for the movement of correspondents and physical and geographical conditions in terms of the conditions for the deployment of communication facilities of various types when determining the quality of the provided communication services.

The closest in technical essence analogue (prototype) to the claimed method is a method of modeling dynamically interacting stationary networks and mobile communication nodes with various interface elements (RF Patent 2723296, IPC H04W 16/22 (2009.01), G06N 30/27 (2020.01), publ. . 09.06.2020). The technical result of the prototype method is to ensure the availability of resources of stationary communication networks for connected to them mobile communication nodes with various interface elements by determining the list of the required number and types of additional interfaces for each given protocol from the list of protocols that ensure the fulfillment of the requirements of the communication network, for each mating node. The technical result is achieved by determining the list of the required number and types of additional interfaces for each specified protocol from the list of protocols that ensure the fulfillment of the requirements for the operation of the communication network for each interfaced node. The initial state of the communication network is simulated taking into account the physical and geographical conditions, the composition and needs of the corporate management system, the telecommunication equipment of the area and the initial position of the mobile component of the communication network. Modeling the functioning of the communication network, taking into account the current changes in the composition, structure and requirements of the management system. Collect statistics on the results of pairing communication nodes. Determine the minimum list of the required number and types of additional interfaces for each specified protocol, in order to meet the requirement for the probability of interfacing any mobile node with any stationary node.

The disadvantage of the prototype method is the lack of an assessment of the spatial availability of resources of stationary communication networks for mobile elements of correspondents, taking into account the density of telecommunication equipment of the area and the technical capabilities of the nodes of the stationary network to provide communication services with the required quality.

The technical problem to be solved by the proposed solution is the low spatial availability in a given period of time of the resources of stationary communication networks for mobile elements of KSU, the connection to the communication network of which is often difficult or impossible when the physical and geographical conditions of functional application in areas with different telecommunication equipment change. terrain.

The technical problem is solved due to the consistent and reasonable determination of the required types and number of communication means that provide a given spatial availability of fixed communication network resources for the mobile elements of the KSU.

The technical result of the invention is to provide a given spatial availability of fixed communication network resources for mobile elements of a corporate control system, taking into account the dynamics of their movement and physical and geographical conditions by determining the types and number of communication means for deploying reference lines and direct connections in various conditions.

The technical result is achieved by the fact that in the method of modeling the connection of mobile elements of the corporate control system to a fixed communication network, a geographical fragment of the territory is set where the elements of the corporate control system are planned to be located, local fragments of the territory where it is impossible to deploy elements of the corporate control system are set, the number and the composition of bodies, the structure of information directions of the corporate management system, the requirements of the corporate management system for communication services, the time of modeling the process of functioning of the corporate management system, the period of checking the coordinates and operating mode of the mobile elements of the corporate management system, determine the composition and structure of the fixed communication network, connect communication nodes of the elements of the corporate control system to the fixed communication network, generate routing options, select the routing option in the specified information directions with a set of requirements for communication services, form routes between informationally interconnected subscribers of the corporate management system; additionally set the coordinate grid of the geographical fragment of the territory, the requirements of the mobile elements of the corporate control system for the availability of communication services of the fixed network, the rules for moving mobile elements of the corporate control system, types, characteristics, priority and conditions for the use of communication means used for the deployment of reference lines, exclude local fragments of the territory , on which it is impossible to deploy communication lines of a given type, with a given verification period determine the coordinates and mode of operation of the mobile elements of the corporate control system, for each mobile element arriving at the next place of use, according to the functional purpose, determine the maximum possible consumption of communication means by deploying direct communication lines with the required characteristics in each information direction, the distance to all communication nodes of the fixed network is estimated with respect to the conditions for the deployment of communication facilities of various types, for each The same type of communication lines for each mobile element of the KSU build the variation series of communication nodes of the fixed network according to the distances obtained, exclude from the variation series the nodes to which it is impossible to connect due to physical and geographical conditions, estimate the consumption of communication means necessary for the deployment of the binding line of the mobile element of the corporate system control to the nearest node in accordance with the conditions and priority of the use of communication facilities and compare it with the maximum possible consumption of communication facilities, when the maximum possible consumption of communication facilities is exceeded, direct communication lines are deployed in each information direction and the type and amount of spent communication facilities are stored, if the consumption of funds is communication does not exceed the limit value, then the mobile element of the corporate control system is connected to the nearest communication node of the fixed network, routes are formed in the specified information directions, the fulfillment of the requirements for communication services is checked in each information direction and calculate the ratio of the availability of communication services in relation to the amount of services provided with the required quality to the total number of services required for all subscribers of the mobile element of the corporate management system, if the calculated availability ratio meets the specified requirements, then the type and number of communication means spent on binding the mobile the element of the corporate control system to the stationary communication network, if the calculated availability factor does not meet the specified requirements, then the actions to connect the mobile element of the corporate control system to the communication nodes of the stationary network with the next members of the variation series are repeated until due to the total connected nodes communication, the specified requirements for the availability of communication services will not be met, or the total consumption of communication facilities for the deployment of tie lines to the involved fixed network nodes will not exceed the limit value, after at the end of the modeling time for the process of functioning of the corporate control system, for each mobile element, the types and number of communication means necessary for the deployment of binding lines and direct connections are displayed.

From the prior art, no solutions have been identified regarding methods for modeling communication networks characterized by the claimed set of features, which, therefore, indicates the compliance of the claimed method with the "novelty" condition of patentability.

The results of the search for known solutions in this and related fields of technology in order to identify features that match the distinctive features of the prototypes of the features of the claimed invention, have shown that they do not follow explicitly from the prior art. The prior art determined by the applicant has not revealed the influence of the essential features of the claimed invention on the achievement of the specified technical result. Therefore, the claimed invention meets the “inventive step” requirement of patentability.

The "industrial applicability" of the method is due to the presence of an element base, on the basis of which devices that implement the method can be made.

The claimed method is illustrated in FIG. 1 is a block diagram of a method for modeling the connection of mobile elements of a corporate control system to a fixed communication network.

The claimed method is implemented in the form of a simulation block diagram shown in FIG. one.

In block 1 of Fig. 1, a geographic fragment of the territory is set in which the placement of the corporate management system is planned. Geographic coordinates describing the area of a fragment of the territory can be set by entering the specified data into the computer memory (or other storage media) using known input devices, or using known software (for example: software "SAS.Planet", access mode : http://www.sasgis.org/sasplaneta/; Panorama software, access mode: https://gisinfo.ru/products/map12_prof.htm, access date 15.07.2020).

In block 2 of Fig. 1, local fragments of the territory are excluded, in which it is impossible to deploy the elements of the KSU. This action can also be performed, for example, by entering the specified data into the computer memory (or other storage media) using known input devices, or using known software (for example, Software. SAS. Planet. Access mode: http: //www.sasgis.org/sasplaneta/, date of access 07/15/2020).

In block 3 of Fig. 1, the following initial data is set:

1. Coordinate grid of the geographic fragment of the territory, necessary to determine in the future the coordinates of any element of the corporate management system. The coordinate grid can be set using various well-known geoinformation systems (for example: GIS "Panorama", access mode: https://gisinfo.ru/products/map12_prof.htm, access date 15.07.2020);

2. The number and composition of the bodies of the corporate governance system (KSU). The composition of the control bodies is determined by their subscribers participating in the information exchange of the CCU.

3. The structure of information directions of the corporate management system, determined by the needs of its information interconnected subscribers. The structure of information directions is set in the form of a matrix, based on the specified number of bodies and the structure of the corporate governance system.

), то в ячейки памяти, хранящие значения матрицы информационных направлений записывают «1», в противном случае, в ячейки памяти записывают «0» (Патент РФ 2481629, МПК G06F 17/50, опубл 10.05.2012.). Сформированную матрицу записывают в ПЗУ ЭВМ.The matrix of M information directions is a square matrix of size n × n , where n is the number of subscribers of the control system. If the m- th information direction between subscribers exists
(

), then in the memory cells storing the values of the matrix of information directions write "1", otherwise, write in the memory cells "0" (RF Patent 2481629, IPC G06F 17/50, publ. 10.05.2012). The formed matrix is written into the ROM of the computer.

4. Requirements of the corporate management system for communication services. The list of communication services is set for each subscriber, depending on his functional duties and the purpose of the body of the control system. The composition of communication services for each subscriber of the control body determines the criteria for choosing a routing option in the necessary information directions.

5. Requirements of mobile elements of the corporate management system to the availability of fixed network communication services. The indicators of the availability of communication services are the probability of receiving the requested service within a specified time interval. The requirements for the probability and time of receiving services established for mobile elements of the KSU are requirements for availability.

6. Time T of modeling the process of functioning of the corporate management system;

7. Rules for moving mobile elements of the corporate management system, which may include:

- conditions for changing the location of the mobile elements of the KSU;

- directions of movement of mobile elements of the KSU;

- the distance over which the mobile elements of the KSU can move;

- speed of movement of mobile elements of the KSU, taking into account the physical and geographical conditions;

- the limiting time for moving the mobile elements of the KSU;

- intervals of permissible distances between the elements of the KSU;

- etc.

8. The period ∆ t for checking the coordinates and operating mode of the mobile elements of the corporate control system, determined by the minimum stationary time of the corporate control system.

9. Types, characteristics, priority and conditions of use of communication facilities used to deploy anchor lines. The main types of communication facilities include: fiber-optic, electrical conductive, radio relay, satellite, tropospheric. The main characteristics of communication lines include: maximum length, used frequency range, frequency response, attenuation, bandwidth, noise immunity, crosstalk at the near end of the line, data transmission reliability, unit cost, deployment time, etc. etc. The characteristics of communication lines are determined by the characteristics of the transmission medium, the state of communication facilities, weather conditions, the state of the atmosphere, physical and geographical conditions, etc.

The dependence of the characteristics of communication facilities on external conditions determines the stability of the communication lines deployed on their basis and, accordingly, the conditions for using communication facilities. The priority of using communication means is determined by the totality of their conditions of use, quality indicators and the number of communication services provided through the communication lines deployed on their basis.

Thus, fiber-optic communication lines have the best indicators in terms of throughput, error rate, resistance to external influences compared to radio relay lines, but they are inferior to them in terms of deployment time and conditions for placing a transmission medium (for example, laying a cable through a swamp is not practical from a practical point of view, and building a radio-relay interval through it does not present any practical difficulty; or, building a radio-relay interval through a mountain gorge is possible only with direct line of sight, which in practice is a rarity, and an optical cable is laid along any route).

The specified values are recorded in the computer memory.

In block 4 of Fig. 1, the composition and structure of a fixed communication network is determined in accordance with the current telecommunication equipment of a given geographic fragment of the territory, or it is simulated using well-known methods for modeling fragments of communication networks invariant to real fragments of communication networks, using the methods described in (RF Patent 2546318, IPC G06F 17/10 (2006.01), G06F 17/50 (2006.01), H04W 16/22 (2009.01), publ. 10.04.2015; RF patent 2723296, IPC H04W 16/22 (2009.01), G06F 30/27 (2020.01), publ. 09.06.2020; Belikova I.S., Zakalkin P.V., Starodubtsev Yu.I., Sukhorukova E.V.

Access mode: www.bentley.com/ru/products/product-line/utilities-and-communications-networks-software/bentley-fiber) ... This action can be performed by performing operations on the algorithms developed and specified in the listed sources using a computer.

In block 5 of Fig. 1, the communication nodes of the corporate control system are connected to the nearest nodes of the fixed communication network. Connection can be carried out through communication lines with various types of linear path (fiber-optic, conductive, radio relay, etc.).

In block 6 of Fig. 1, routing options are generated between the nodes of the communication network in the necessary information directions.
