The wireless terminal device 100 may be a wireless terminal device of a user that determines a wireless network and requests transmission and reception of wireless data packets. Here, the wireless terminal device 100 may be implemented as various devices such as a smart phone, a tablet computer, a notebook computer, a personal digital assistant (PDA), a portable multimedia player (PMP), a smart watch, and smart glasses.

The wireless network quality measuring unit 110 calculates the quality of the wireless network based on quality variable information including at least one of wireless network speed, signal strength, and network access environment information, and the control unit 120 The quality of the wireless network calculated by the measurement unit 110 is shaped or quantized to be displayed on the display unit 130 and controls the overall operation. The wireless network quality measurement unit 110 or the control unit 120 may be implemented with an application processor or the like.

The wireless network quality measurement unit 110 collects the frequency band of the wireless network as a model setting variable, determines a network quality relational expression compared to the signal strength (RSSI) for the frequency band as an application function of the quality prediction model, and The quality of the wireless network can be calculated by using as a model input variable. Here, the relationship between signal strength and network quality may include a linear function, a logarithmic function, a sigmoid function, and an arctan function.

In another embodiment, the wireless network quality measurement unit 110 may use a frequency band of a wireless network as a model setting variable, and determine a relationship of network quality versus signal strength for a corresponding frequency band as a quality prediction learning model. In addition, the relationship learning operation can be performed by using the signal strength and network quality, which are the input and output values of the relational expression as model input variables, as data for regression analysis learning on the relational expression, and learn the signal strength, which is a part of the model input variable. The quality of the wireless network can be predicted by using it as an input value of the relational expression.

The wireless network quality measurement unit 110 can collect and process model settings and input variables from internal information of the wireless terminal device 100, as well as variable data sets received from remote external devices. By collecting and processing data as variables or collecting and processing data input from users as variables, generating a quality prediction model for each wireless network from variables collected and processed through various routes, and various input variables corresponding to the generated models and situations Can handle.

It is possible to predetermine a quality prediction model according to a set variable for each network corresponding to a plurality of accessible wireless networks, calculate the quality prediction information for each network compared to the current input variable based on this, and calculate the quality reduction for each wireless network based on various variables. By predicting in advance by the process of and displaying the quality of each network on the screen, it is possible to provide a dynamic variable access of a wireless network or a variable selection access of a user.

The variable information applied to the quality prediction model may include, for example, a constant element and a variable element, and the constant element and the variable element may be used as part or all of a model setting variable and a model input variable.

Here, the constant factor is a factor in which the degree of influence on the quality of the wireless communication network is invariant, and the wire cable performance information, the hardware performance information of the AP, and the communication protocol corresponding to the wireless section between the AP and the wireless terminal device (e.g., WIFI network In the case of, standard-based protocols such as 802.11n, 802.11ac, or encryption protocols such as OPEN, WEP, WPA2, and standard-based protocols such as GSM, LTE-A, and LTE for mobile communication networks), frequency band and channel information of the AP , The number of neighboring APs, and the like may be exemplified.

Therefore, detailed relational expressions for quality measurement, relational expressions using information on each variable, model setting, and descriptions of specifically applying relational expressions or quality variables applied to the model are omitted. For example, for network quality information, the frequency band of the wireless network is collected as a model setting variable, the relationship of network quality compared to the signal strength (RSSI) for the frequency band is determined as an application function of the quality prediction model, and the signal strength is modeled. It can be used as an input variable to calculate the quality of the wireless network.

Meanwhile, when the quality of the wireless network that has been digitized or classified is changed, the control unit 120 may display a value or shape corresponding to the change on the display unit 140.

The control unit 120 checks the quality fluctuation of the connected network, and when fluctuations exceeding the preset upper and lower limit thresholds occur, overlays the quality change information on the screen to display at least one of a text, a shaped image, and a numerical value. It can inform of quality fluctuations. In addition, quality fluctuations can be notified by alarm or vibration.

In addition, network information having the highest network quality may be selected from a list of accessible wireless networks, and a screen display may be provided to a user to select a network change connection. Alternatively, if the quality falls below the lower limit threshold in the initial setting, a pop-up window can be displayed and the control can be controlled to automatically connect to the highest quality network.

Here, the shape is not limited to an image such as a figure or picture, but may be a phrase such as a letter, and the degree of filling, number, color, and shape transformation of the same figure or image, simple addition or transformation of a bar shape, animation It can also be a moving or fluctuating shape such as. In addition, a numerical value or shape representing the quality of the wireless network may be displayed in combination with the signal strength indication of the existing wireless network.

As an example, the searched Wi-Fi in the Wi-Fi search window may be displayed in a shape in which signal strength and quality are combined (FIG. 2(A)). In another embodiment, a single or a plurality of wireless networks may be displayed in a shape in which signal strength and quality are combined (Fig. 2(B), (C)).

In addition, it is possible to display the quality change of the wireless network by means of vibration, flash, alarm, etc., as well as numerical values or shapes (Fig. 2(D)).

On the other hand, when the digitized or classified quality changes, when a specific screen is being displayed on the display unit 130, the controller 130 determines the digitized or shaped quality changed in the display unit 130 as shown in FIG. It can also be overlaid on and displayed.

In addition, as shown in FIGS. 4A and 4B, quality display information enlarged on the entire screen may be displayed, or the quality may be displayed by overlaying it on a background screen, thereby indicating a quality change state. In addition, it can be notified by a pop-up window, or a quality change can be notified by including an alarm or vibration. In addition, when the quality drops below the set threshold, the network can be automatically changed to a high-quality network and connected, and a network search window that can be connected is popped up so that the user can select and change the connection, and each network product is displayed. , It is possible to automatically select the network with the best quality and allow the user to select a connection.

If the quality decreases due to quality fluctuations, the user checks the network search window and changes to a network with good quality on the screen displaying the quality status of each network as shown in Fig.2(A) and connects to a network connection with good quality.
