1 is a conceptual diagram of a wireless network quality measurement system according to an embodiment of the present invention, Figure 2 shows the flow of data used in the wireless network quality measurement system shown in FIG.

Referring to FIGS. 1 and 2, a wireless network quality measurement system 10 includes a client 100, a server 200, and a base station 300. Although only one client 100 is shown in FIGS. 1 and 2 for convenience of description, the wireless network quality measurement system 10 may include a plurality of clients. In addition, although only one base station 300 is shown in FIG. 1 for convenience of description, the wireless network quality measurement system 10 may include a plurality of base stations.

The client 100 and the server 200 can transmit and receive data through various wired and wireless networks, for example, a wireless network through the base station 300.

The client 100 transmits the location information data of the client 100 to the server 200 (S100). According to an embodiment, the location information data may be global positioning system (GPS) data. According to another embodiment, the location information data may be obtained by cell tower triangulation or a Wi-Fi based positioning system (WPS).

The server 200 generates a test plan based on the location information data received from the client 100 (S110), and transmits the generated test plan to the client 100 (S120).

The test plan may include data of at least one of an identification number, priority of the client 100, a type of a wireless communication network to be measured, a measurement object, and a parameter to be measured. The priority may be determined according to the policy of the mobile operator, for example, the importance of the region where the client 100 is located, based on the location information data of the client 100.

According to another embodiment, a user of the client 100 may directly create a test plan and input the created test plan into the client 100.

According to an embodiment, the types of wireless communication networks to be measured include a global system for mobile communication (GSM), general packet radio services (GPRS), code devision multiple access (CDMA), evolution data optimized (EVDO), wideband code devision multiple (HSDPA), high speed uplink packet access (HSUPA), third generation partnership project long term evolution (3GPP), or wireless fidelity (Wi-Fi) Do not.

According to an embodiment, the measurement type may be at least one of a voice call, a file transfer protocol (FTP), a hypertext transfer protocol (HTTP), a ping, and an electronic mail, but is not limited thereto. Do not.

According to an embodiment, the parameters to be measured are energy carrier-to-interfrence density (Ec / Io), receive power, transmit power, block error rate (BLER), and RSCP (recieved). signal code power, signal to interference plus noise ratio (SINR), and throughput, but is not limited thereto.

For example, the server 200 may generate a test plan for measuring a call success rate when transmitting a voice call through the 3GPP LTE and transmit the test plan to the client 100. For example, when the server 200 uploads data to the FTP server via WCDMA, the server 200 generates a test plan for measuring Ec / Io, received power, transmit power, BLER, RSCP, and SINR, Lt; / RTI >

The client 100 measures the wireless network quality based on the test plan received from the server 200, and generates a log file for the measured wireless network quality (S130). The log file may include at least one of location information of a measurement location, a measurement time, a type of a measured wireless communication network, a measurement object, a measured parameter, and a measured value.

According to an embodiment, the client 100 may generate the log file only when the measured wireless network quality is out of a threshold range, for example, a good wireless network quality. The method in which the client 100 generates the log file only when the measured wireless network quality is out of the threshold range will be described in more detail in FIG. 3.

The client 100 transmits a log file reception request signal for requesting reception of a log file to the server 200 (S140), and the server 200 responds to the log file reception request signal received from the client 100. It is determined whether a log file is received (S150).

The server 200 may determine whether to receive a log file based on a free resource of the wireless communication network quality measuring system 10 and a priority of the client 100. According to an embodiment, the free resource may be information about a load of a central processing unit (CPU) of the server 200, a free memory, or a free bandwidth of a network.

The server 200 transmits a log file transmission request signal for requesting the transmission of a log file to the client 100 that outputs a log file reception request signal when the free resource is greater than or equal to a threshold value, and when the free resource is less than or equal to the threshold value. According to the priority of the client 100, the log file transmission request signal may be transmitted to the client 100.

That is, when the server 200 receives log file reception request signals from each of the plurality of clients, but the free resource is insufficient to simultaneously receive log files from each of the plurality of clients, the server 200 based on the priority of each client. You can determine whether you have received a log file.

The server 200 transmits a log file transfer request signal for requesting the transfer of the log file to the client 100 according to the determination result, and the client 100 sends the log file transfer request signal to the server 200 in response to the log file transfer request signal. The log file is transmitted (S170).

In other words, when the free resources are insufficient, the server 200 may determine the reception order of log files according to the priority of each client, and receive the log file from each client according to the determined reception order.

FIG. 3 is a flow chart for explaining an embodiment of generating a log file by a client shown in FIG. 1, and FIG. 5 is a graph of wireless network quality measured by the client shown in FIG. 1. Indicates.

Referring to FIG. 3, the client 100 measures wireless network quality according to a test plan received from the server 200 (S200). The client 100 determines whether the measured wireless communication network quality is within a threshold range (S220).

According to the determination result, when the measured wireless network quality is within a threshold range, the client 100 may again measure the wireless network quality according to the test plan without generating a log file. When the measured wireless network quality is out of the threshold range (400-1 or 400-2 of FIG. 5), the client 100 generates a log file (S240) and transmits the generated log file to the server 200. (S250).

Accordingly, the wireless network quality measurement system 10 can reduce the load of the wireless network quality measurement system 10 by reducing the transmission and reception of unnecessary log files.

4 illustrates a flow of data used in a wireless network quality measurement system when a client shown in FIG. 1 receives a drawing image from a server.

Referring to FIG. 4, each of a plurality of clients including the client 100 previously photographs a drawing image of a building (S300), and photographs the drawing image, building information, and location information of a building in the server 200. Can be transmitted to (S310). The building information may include data on the name or address of the building, and the location information may be GPS data of each client when each client images the drawing image.

The server 200 stores the photographed drawing image, the building information, and the location information received from the client 100 in a database.

When the drawing of the building is required, the client 100 requests the drawing search to the server 200 (S320). The server 100 generates a list of buildings having location information close to the location information of the client 100 in response to the drawing search request received from the client 100 in operation S330, The list is transmitted (S340).

The client 100 selects one of the lists of buildings received from the server 100 in operation S350 and transmits the selected building information to the server 100 in operation S360.

The server 200 searches the database for a drawing image corresponding to the building information received from the client 100 in operation S370 and transmits the drawing image corresponding to the retrieved building information to the client 100 in operation S380.

The client 100 may reference the received drawing image to a wireless network quality measurement within a building, e.g., a subway platform. The client 100 can measure the wireless network quality of the more accurate position using the base station triangulation or Wi-Fi based positioning system based on the received drawing image even when the GPS is not received.

The client 100 may be implemented as a mobile device such as a portable computer, a mobile phone, a smart phone, a tablet computer, or a personal digital assistant (PDA).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
