The present invention relates to a wireless network planning system and method in consideration of a radio environment capable of guaranteeing a quality of service while minimizing network construction costs by dividing cells according to a radio environment of a region in which a wireless network is constructed, and a terminal apparatus for performing the same. .

Recently, as energy and environmental issues have emerged as major issues, research on the Smart Grid, a next-generation power grid that optimizes energy efficiency by integrating information and communication technology into the power grid, exchanging real-time information in both directions by the power providers and consumers Actively done.

Smart Grid collects electricity usage, supply and power line status using a power meter called a smart meter, and dynamically adjusts the power supply by grasping power usage in real time based on the collected information. In other words, it is implemented to efficiently manage power by providing it to consumers.

When using such a smart grid, it is possible to reduce the amount of energy during low power usage, to use the remaining power elsewhere, or to store and supply the power during high power usage. It is expected to be able to prevent the failure of.

As a method of building such a smart grid, first, a mobile communication module is installed in each smart meter, and the measurement results of each smart meter are transmitted to a central center through a mobile communication network. After the measurement information of the meter is collected by the indoor device, and transmitted to the central center through the Internet. Third, after collecting the measurement information of the smart meter to the local collection device using M2M (Machine to Machine) communication, the local collection A method for transmitting a device to a central management device through a communication network including a mobile communication network has been proposed.

1 is a diagram illustrating an example of a smart grid system, and illustrates a case where the third method is applied.

Referring to FIG. 1, after configuring a multi-hop network using M2M communication between a plurality of smart meters 11, the measurement information of the plurality of smart meters 11 is transferred to the local collection device 12 through M2M communication. When transmitting, the local collection device 12 transmits the measurement information collected from the plurality of smart meters 11 to the central management device 14 via the communication network 13. This structure has an advantage that the number of lines using the communication network 13, more specifically, the mobile communication network, is low, and that it can be constructed even in an area where wired Internet connection is difficult.

However, in this case, a wireless network capable of M2M communication between the smart meters 11 should be established. Since the communication range of the smart meters is small within several tens of meters, the channel environment may vary greatly depending on the regional and spatial characteristics. have. Therefore, if proper network planning is not performed, after installing the smart meter, a number of additional operations such as position adjustment or transmission power correction may occur, which may result in unnecessary cost.

Therefore, in order to ensure a certain level of service quality in consideration of the radio wave environment of the region, and to minimize the network construction cost by reducing the occurrence of additional work, the coverage area of the local collection device that collects the measurement information of multiple smart meters is collected. There is a need for network planning to properly partition the corresponding cell.

On the other hand, network planning technology is used to secure the maximum coverage at a low cost in mobile communication networks. However, in the case of mobile communication networks, the coverage radius of each base station is wide from several hundred m to several km, which greatly affects the regional radio environment. Since it is not received, it is inefficient to apply the network planning technology applied to the mobile communication network to the construction of a wireless network with a small cell radius as in the smart grid.

The present invention has been proposed to efficiently construct a wireless network having a small difference in radio environment for each cell due to a small communication radius, and the service quality can be minimized by minimizing the network construction cost by dividing the cells according to the radio environment of the region where the wireless network is constructed.

However, in the following description and the accompanying drawings, detailed descriptions of well-known functions or configurations that may obscure the subject matter of the present invention will be omitted. In addition, it should be noted that like elements are denoted by the same reference numerals as much as possible throughout the drawings.

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

2 is a flowchart illustrating a wireless network planning method in consideration of a radio wave environment according to the present invention.

The present invention intends to construct a wireless network more efficiently by varying cell division for each region in consideration of a radio wave environment having a large difference according to regions.

To this end, in the present invention, first, classification system definition information for defining segment regions having different propagation environments is set in consideration of differences in propagation environments (S110). More specifically, the classification system definition information is a classification criterion for areas with different radio wave environments. For example, the radio environment in rural areas with few radio wave obstructions and in urban areas with many radio wave obstructions differs greatly. There is a difference in the radio wave environment of residential and commercial areas. By analyzing the radio wave environment difference, it can be seen that the radio wave environment can be classified according to the land use of the region. Therefore, in step S110, the classification system definition information is set based on the land use. For example, the classification system definition information may be set as a segment area by dividing a high-rise residential area, a low-rise residential area, a commercial area, an industrial area, a green area, a forest area, a farming and fishing area, and a road.

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

3 is a diagram illustrating a wireless network construction area according to the present invention. In the present invention, the cluster area 31 for a wireless network is classified into a plurality of segment areas 32 having different propagation environments. Each segment region 32 classified as a difference in environment is divided into one or more cell regions 33 each adapted to the characteristics of the propagation environment. In the step S120, the size and shape of the cell region 33 according to the classification type of the segment region 32 for cell division according to the propagation environment for each segment region 32 classified according to the classification scheme definition information. Define at least one of (S120). For example, the cell size is defined as 40 * 40 for areas with low interference such as roads, parks, green areas, forests, etc., and in areas with high interference such as residential and commercial areas. The cell size can be set as small as 20 * 20. In addition, in the case of the building contained in each area | region, a cell is defined as the polygon shape formed by connecting the boundary of a building, without restricting the size and shape. In addition, a cell shape and a size may be separately defined for a part that can be divided into specific uses such as a road.

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

Next, the wireless network is divided 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 (S140). ). In this case, a unique ID is assigned to each divided cell area. The attribute defined in step S130 is inherited in the divided cell area. For example, in step S140, the segment area 32 corresponding to the farming area, the green area, and the forest area is divided into 40 * 40 units, and each cell is assigned a unique cell ID. For the segment area corresponding to the area, each building included in the area is set to one cell area to give a cell ID, and for other areas, the cell ID is divided into 20 * 20 units.

According to the above, one cluster area is not all composed of cells of a constant size, but is composed of cells of different sizes and shapes according to differences in propagation environment. The cell division result of step S140 may be provided to the user, and the user may install the wireless network equipment (eg, smart meter, local collection device) for each divided cell area by referring to the cell division result. Thus, a wireless network can be constructed.

In addition, in the wireless network planning method according to the present invention, in addition to the propagation environment attribute defined in the step S130, it is possible to further perform radio analysis prediction on the divided plurality of cell regions (S150). ). In this case, the radio wave analysis may be performed mainly on a building.

In addition, the wireless network planning method according to the present invention may further provide the best installation position of the wireless network equipment through the derived radio wave analysis prediction result (S160). On the basis of the information, the installation of the wireless network equipment and network construction can be made easier.

However, even after constructing the wireless network, the radio wave 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 radio wave information from each installed wireless network equipment after the wireless network construction is completed (S170).

This is to monitor the radio wave environment change in real time, and may analyze the radio wave environment change based on the collected radio wave state information, and further provide the radio wave environment change information to the user (S180). Based on this, the user can perform additional tasks to build an optimal network.

In addition, the wireless network planning method according to the present invention may provide network correction information, for example, installation position adjustment information, transmission power correction information, etc. according to the analyzed radio wave environment change for easier correction operation. (S190). In this case, by providing accurate network correction information based on the change in the radio wave environment, additional work for network construction can be performed quickly.

The wireless network planning method in consideration of the above-mentioned propagation environment may be implemented in a software form readable by various computer means and recorded on a computer readable recording medium. Here, the recording medium may include a program command, a data file, a data structure, etc. alone or in combination. Program instructions recorded on the recording medium may be those specially designed and constructed for the present invention, or they may be of the kind well-known and available to those having skill in the computer software arts. For example, the recording medium may be magnetic media such as hard disks, floppy disks and magnetic tapes, optical disks such as Compact Disk Read Only Memory (CD-ROM), digital video disks (DVD), Magnetic-Optical Media, such as floppy disks, and hardware devices specially configured to store and execute program instructions, such as ROM, random access memory (RAM), flash memory, and the like. do.
