Description

System for forming a radio frequency network and method of operating the same

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for configuring a radio frequency network and a method of driving the same. In particular, in the case of configuring a radio frequency network, various types of information affecting a frequency network to be constructed are stored in a database and stored in a predetermined memory structure. By selecting the candidate frequencies to be used in the frequency network by comparing / analyzing and selecting the optimal frequency using fuzzy theory among the selected candidate frequencies to form a frequency network, when many frequencies of a limited band are used, The present invention relates to a radio frequency network configuration system capable of minimizing radio communication interference and a driving method thereof.

Wireless mobile communication is widely used for many advantages, and the method has been widely used in public communication networks such as automobiles, wireless calling, and portable telephones. The future challenges of wireless mobile communication as a means of communication in the 21st century can be called the development of new frequency bands, the improvement of frequency utilization technology, the miniaturization of terminals, information processing and service methods, and the development of various systems.

In recent years, as the use of radio frequencies rapidly increases due to the development of wireless mobile communication, when a network is wirelessly configured, many frequencies are used in a predetermined region due to a limited band. For this reason, studies have been actively conducted to efficiently manage radio communication failures such as interference between adjacent frequencies.

Radio frequency results in various communication results, that is, various communication obstacles depending on various environments of the connection area. The various factors that cause such communication obstacles are diverse and their predictions are very difficult because they do not have a constant correlation between them.

Accordingly, the conventional technology used a method of separating the frequencies to be used for each region in consideration of the frequency situation of all regions in each region when constructing a radio frequency network. In particular, the method of applying the information about the region, the distance on the link, and the relationship with the existing frequencies is simply determined by the user.

However, this method is possible in the case of a simple radio frequency network, but it is not possible to rely on simple calculation and trial and error methods when it is necessary to overlap a predetermined frequency band due to the complexity of the network and the lack of the frequency band. Many time and economic problems will arise.

Accordingly, an object of the present invention is to provide a radio frequency network configuration system and a driving method thereof for minimizing radio communication failure due to interference when many frequencies of a limited band are used when configuring a network network wirelessly.

It is still another object of the present invention to provide a system for configuring a radio frequency network and a method of driving the same for systematically managing use frequencies in all regions using a wireless network.

It consists of a link setting means 7 for the purpose.

The regional classification means 1 is characterized by the characteristics of the area, for example, the terrain type between the two links constituting the radio frequency network, the distance between the two links and the direction of the antenna, the current status of the other links formed between the two links, Each link area characteristic such as frequency information and link information in a radio frequency network excluding the network implemented by the system is set as a first parameter so as to be calculated by formulating and separated for each link and transmitted to the first storage means 2. .

The first storage means 2 has a predetermined memory structure so that data can be modified, deleted, stored, and loaded from time to time, so that the first parameter for each link transmitted from the local means 1 can be changed from time to time. In addition to storing the data, the frequency allocation means 3 and the candidate frequency selecting means 5 are configured to load the first parameterized data.

The frequency distribution means 3 distributes the frequency for each link with reference to the first parameter stored in the first storage means 2. For example, according to the distance between two links, a low frequency band is allocated when the distance is far, and a high frequency band is allocated when the distance is close. Position coordinates between link regions where the link-specific frequency allocated by this method is used (for example, the position coordinate of a link appearing on the map sets the second parameter by displaying latitude as X axis and longitude as Y axis). Is defined as the coordinate axis to set the second parameter and transmit it to the second storage means (4).

The second storage means 4 has a predetermined memory structure so as to modify, delete, store and load data from time to time. It is configured to store the data and to load the second parameterized data in the candidate frequency selecting means (5).

In this step (S1), the characteristics of the area, for example, the terrain type, the distance between the two links, and the antennas, can be obtained by collecting opinions from experts or experienced users, or by means of pre-calculated RF efficiency. Set as the first parameter to formulate and calculate the characteristics of each link area such as the direction of, the status of other links formed between the two links, frequency information and link information in the radio frequency network excluding the network currently implemented by this system. And separate by link.

The separated first parameters are stored in a database (S2). In this step S2, the first parameter set in the previous step S1 is converted into data and stored in a predetermined memory structure that can be modified, deleted, stored, and loaded.

Using the stored first parameter, the second frequency defining the positional coordinates between the link regions in which the distributed frequency is used is distributed as well as distributing the used frequency for each region (S3). In this step S3, a frequency to be used between link regions is allocated with reference to the first parameter. For example, according to the distance between two links, a low frequency band is allocated when the distance is far, and a high frequency band is allocated when the distance is close. In addition, the position coordinate between link regions where the assigned link frequency is used (for example, the position coordinate of the link appearing on the map sets the second parameter by displaying latitude as X axis and longitude as Y axis). Define the second parameter.

The second parameter set in the previous step (S3) is stored as a database (S4). In this step S4, the second parameter set in the previous step S3 is data-stored and stored in a predetermined memory structure that can be modified, deleted, stored, and loaded.

The candidate frequency to be used in link formation is selected by comparing / analyzing the first parameter and the second parameter (S5). In this step (S5), the first parameter and the second parameter are loaded to select candidate frequencies that can be used when constructing a new link through comparison / analysis using a predetermined structure query language (SQL) statement.

By comparing / analyzing the selected candidate frequencies, an optimal frequency to be used when forming a new link is selected (S6). In this step S6, each third parameter is set for each candidate frequency selected in the previous step S5, the third parameters are set as input values of the fuzzy theory, and the conditions of the candidate frequencies are compared according to the fuzzy theory. To select the optimum frequency.

In addition, in this step (S6), if the optimum frequency is not selected by the candidate frequency, it is also possible to select the optimal frequency by comparing / analyzing the frequencies not used for links in other regions.

A new link is established using the selected optimal frequency (S7). In this step S6, a new link is established using the optimal frequency selected in the previous step S6.

In addition, the position coordinate between link regions where the assigned link frequency is used (for example, the position coordinate of the link appearing on the map sets the second parameter by displaying latitude as X axis and longitude as Y axis). In addition, the second parameter is defined and stored in the second storage means 4 in a database.

Subsequently, the candidate frequency selecting means 5 loads the first parameter and the second parameter and selects candidate frequencies usable when constructing a new link through comparison / analysis using a predetermined structure query language (SQL) statement. .

Is set. In addition, when the distance between two points of the newly formed link 8 is very far and the frequency bands of the links 12 to 17 of the peripheral other systems passing between the two points are set to the low range, the candidate frequencies are linked to the other systems. The frequency band used for the links 15 to 17 formed at the furthest distance among the 12 to 17 is set.

Subsequently, the optimum frequency selecting means 6 sets each third parameter for each selected candidate frequency, sets the third parameters as input values of the fuzzy theory, compares the conditions of the candidate frequencies according to the fuzzy theory, and then optimizes them.
