Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the accompanying drawings, detailed description of well-known functions or constructions that may obscure the subject matter of the present invention will be omitted. It should be noted that the same constituent elements are denoted by the same reference numerals as possible throughout the drawings.

In describing the present invention, first, a method of planning a wireless network according to the present invention will be described, and then a configuration of a system, a service apparatus, and a terminal apparatus for implementing the method will be described.

2 is a flowchart illustrating a method of planning a wireless network considering the propagation environment according to the present invention.

The present invention attempts to construct a wireless network more efficiently by considering cell division in each region in consideration of a propagation environment with a large difference depending on a region.

To this end, in the present invention, classification scheme definition information defining a segment area having a different propagation environment is set in consideration of a difference in propagation environment (S110). More specifically, the classification system definition information is a classification criterion for areas having different propagation environments. For example, the propagation environment of urban areas having a large number of radio wave obstructions differs greatly in rural areas and buildings where radio wave obstructions are small, , There is a difference in the propagation environment between residential and commercial areas. By analyzing the propagation environment difference, it can be understood that the propagation environment can be classified according to the use of the land in the area. Therefore, in step S110, the classification scheme definition information is set based on the land use. For example, the classification system definition information may be segmented into high-rise residential areas, low-rise residential areas, commercial areas, industrial areas, green areas, forest areas, rural areas, roads, and the like.

Then, the present invention sets cell definition information for each classification type (S120). The cell definition information is information for setting a cell area to be suitable for a propagation environment according to a classification type, and may include, for example, a cell size, a cell shape, and the like. This can be set differently according to the classification type of the segment area.

FIG. 3 is a diagram showing a wireless network construction area according to the present invention. In the present invention, a cluster area 31 for a wireless network is classified into a plurality of segment areas 32 having different propagation environments, Each of the segment regions 32 classified by the difference in environment is divided into one or more cell regions 33 each matching the characteristics of the propagation environment. In step S120, the size and shape of the cell region 33 are determined according to the classification type of the segment region 32 for each cell segment 32 classified according to the propagation environment, (S120). For example, for areas with low levels of radio disturbance, such as roads, parks, and forests, define a cell size of 40 * 40, The cell size can be set to be as small as 20 * 20. In the case of a building included in each area, the cell is defined as a polygonal shape formed by connecting boundaries of buildings without limiting the size and shape. In addition, the cell shape and size can be separately defined for a portion that can be classified into a specific use such as a road.

In addition, the present invention defines a propagation environment attribute for each segment region for radio wave analysis prediction (S130). For example, for each segment area, the classification attribute of the propagation environment, the cell upper object information, the cell upper method, and the like are defined as DB attributes, and the cell area is defined as a space that affects radio waves such as radio wave environment, area, Non-spatial information other than spatial information such as a base station, a repeater, a concentrator, and an antenna distance, and a cell case method for analyzing a propagation environment are defined as DB attributes. This information is used to predict the radio wave analysis of the wireless network to be constructed later.

Next, the area in which the wireless network will be constructed is classified into a plurality of segment areas based on the classification scheme definition information, and then each segment area is divided into a plurality of cell areas according to the cell definition information for each classification type (step S140 ). At this time, a unique ID is assigned to each divided cell area. The property defined in the step S130 is inherited to the divided cell area. For example, in step S140, the segment area 32 corresponding to the agricultural forest area, the green area, and the forest area is divided into 40 * 40 units, each cell ID is assigned to each segment, For each segment area corresponding to the area, each building included in the area is set as one cell area to give a cell ID, and the remaining areas are divided into 20 * 20 units to give a cell ID.

According to the above, one cluster region is not made up of cells of a certain size, but cells of different sizes and shapes are formed in accordance with the propagation environment difference. The user can provide the cell division result of the step S140 to the user and the user can install the wireless network equipment (for example, smart meter, local collection device) for each divided cell area So that a wireless network can be constructed.

In addition, in the wireless network planning method according to the present invention, the propagation analysis prediction can be further performed on the divided plurality of cell areas with reference to the propagation environment property defined in step S130 (S150 ). At this time, radio wave analysis can be done by building.

In addition, in the wireless network planning method according to the present invention, it is possible to further provide the optimal installation location of the wireless network equipment through the derived radio wave analysis prediction result (S160). The installation of the wireless network equipment and the construction of the network can be performed more easily based on the information.

However, even after establishing the wireless network, the propagation environment may change according to the change of the surrounding environment.

To this end, the wireless network planning method according to the present invention may further collect the radio wave information from each installed wireless network equipment after the wireless network construction is completed (S170).

This is for monitoring the change of the propagation environment in real time, and it is possible to further provide the user with the propagation environment change information by analyzing the propagation environment change based on the collected propagation state information (S180). Based on this, the user can perform additional tasks so that an optimal network can be established.

In addition, the wireless network planning method according to the present invention can provide network correction information, for example, installation position adjustment information, transmission power correction information, and the like, in accordance with the analyzed propagation environment change for easier correction work (S190). In this case, accurate network correction information based on the propagation environment change is provided, so that additional work for network construction can be performed quickly.

The wireless network planning method considering the propagation environment described above may be implemented in a form of software readable by various computer means and recorded in a computer-readable recording medium. Here, the recording medium may include program commands, data files, data structures, and the like, alone or in combination. Program instructions to be recorded on a recording medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of computer software. For example, the recording medium may be an optical recording medium such as a magnetic medium such as a hard disk, a floppy disk and a magnetic tape, a compact disk read only memory (CD-ROM), a digital video disk (DVD) Includes a hardware device that is specially configured to store and execute program instructions such as a magneto-optical medium such as a floppy disk and a ROM, a random access memory (RAM), a flash memory, do.
