In general, in a wireless network design and management apparatus, data of a geographic information system (hereinafter referred to as a GIS) is used to determine a rough location of a wireless base station. The GIS data has been used to focus on radio wave analysis functions such as cell coverage.

In addition, when there is a shadow area between the coverage of existing base stations, there is a need to install a new base station. In this case, the continuous wave transmitter is installed at the candidate base station to select the base station location, and the continuous wave is continuously generated by using the frequency of the part of the commercial frequency band of the mobile communication network that is not used by the base station. The base station is selected by measuring the received signal strength of the continuous wave while moving around the continuous wave transmitter.

Until now, the location of the base station was directly indicated and managed in order to select the location of the base station. However, this has been inconvenient to manage the base station when a change such as relocation of the base station occurs or an operation agent is changed.

In addition, it was inconvenient not to check the quality measurement data of the base station directly in the field, nor to confirm the degree of customer complaints online. In addition, it was difficult to obtain third-party base station information without a site visit.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 illustrates a base station positioning system according to the present invention.

Referring to Figure 1, the base station positioning system 100 base station positioning server 100, the Internet 200, field information management server 300, radio wave measurement database 310, public information database 320, customer complaint information database 330, a radio wave comparison analysis server 400, a base station information database 410, a geographic information database 420, and a plurality of field mobile vehicles 500.

The field information management server 300 measures the position of the site provided from the plurality of field mobile vehicles 500 and the radio wave at the position, and transmits the measured information to the radio wave measurement database 310 together with the position information. Save it. That is, the field information management server 300 forcibly transmits continuous radio waves from the base station or stores actual measurement data of the site obtained by the mobile vehicle 500 measuring the radio waves radiated from the base station. Receives complaints about poor customer calls or complaints about poor customer calls received through the Internet, and stores the complaint information in the customer complaint information database 330 together with the poor call area.

The public information database 320 interoperating with the field information management server 300 stores information on base stations of other wireless mobile communication providers installed in each region, and periodically updates the information. Based on the information stored in the common information database 320, the base station of another wireless mobile communication provider that can be shared before the base station is installed in a region where the radio wave is weak or where there are complaints about poor communication of customers It can be determined whether it exists.

In order to manage the base station, the radio comparison analysis server 400 makes a database of the location information and the signal information indicating the location of the base station directly in the drawing to the base station information database 410 and the geographic information database 420, respectively. Save and compare radio waves more effectively. That is, the radio wave comparison analysis server 400 is a network design tool using a prediction algorithm for propagating a predetermined radio wave. The base station positioning server 100 includes a radio wave measurement database 310 and a common information database 320. ), The field information management server 300 interworking with the customer complaint information database 330, the base station information database 410, and the radio wave comparison analysis server 400 interworking with the geographic information database 420 are connected to the Internet network. . Accordingly, the base station positioning server 100 sets the optimal base station position by combining existing data and updated data in real time. The base station position setting method of the present invention configured as described above will be described. The setting server 100 temporarily sets a first position to establish a base station using the measured propagation characteristic. That is, when the base station is installed at the first location, the reception level RX and the interference signal Ec received at the base station at the first location in order to predict the radio wave according to the altitude, the height, the direction, and the output of the base station. / Io). In order to install the base station in a more suitable place, a temporary position is temporarily set to a second position away from the first position, and the reception level RX received at the base station of the second position is performed. And the simulation of the interference signal (Ec / Io). If possible, the third to nth positions are temporarily set to execute the simulation for the reception level and the interference signal (Ec / Io) to obtain a more appropriate position. You can find it. In other words, a simulation is performed on the reception level and the interference signal (Ec / Io) received at the base stations of the first to nth positions to set the position of the base station that achieves the optimal network design. In this case, the location information is formed by latitude and longitude coordinates received from the GPS, and the signal information is formed by an electric field strength, that is, a reception level, received from the base station. The interference signal is also arithmetic generated from the reception level. The location information and the signal information are used to display a color corresponding to the signal strength in a BIN (area having a predetermined width) on a map of a location designated by a user. For example, using a HATA model or a Lee model In order to perform the simulation, a pathloss of a specific area is calculated by using a reception level and a radio wave attenuation coefficient (tilt) of a specific area to estimate the reception field strength, that is, the reception level RX of the mobile terminal. In addition, the interference signal is arithmetically predicted from the neighbor base station reception level stored in the field information management server 300. The interference signal is represented in the format of the ratio of all interference per energy to frequency per chip of the pilot signal received in each BIN (area having a certain width). Thus, the base station selected as a candidate is extracted from the measured radio waves. If the position is within the network design criterion from the value predicted by the radio wave comparison analysis server 400 using the reception level and the interference signal, the position becomes an appropriate position to establish the base station. In other words, in order to find an appropriate position for establishing the base station, The base station that transmits the strongest of the pilot signals from all the base stations or sectors received by the mobile terminal in the BIN is designated as the best server. [0025] In addition, the transmission output for each channel of the base station in the BIN is a received signal, i.e. Adjusted with reference to the power intensity (RSSI) in the mobile terminal. The received signal refers to the total power up to the traffic channel, including the overhead channel received for each BIN upon emission. The embodiment of the present invention is only one embodiment, and does not depart from the gist of the present invention. Of course, many modifications and variations of the components of the present invention are possible, of course, the present invention is not limited only to the embodiments.

As described in detail above, according to the base station location setting system of the present invention, even if the replacement of the operating personnel, or the wireless network design personnel do not visit the site by using visual information to easily locate the location of the base station By accurately understanding the relationship with the structure and structure, it not only shortens the time required for design, but also has the advantage of reducing cumbersome base station visits. In addition, by wirelessly accessing various databases, it provides the best environment for improving call quality.
