Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

The GPS module 115 calculates distance information and accurate time information from three or more satellites and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude can do. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 can calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal by using the GPS module in the shadow area of the satellite signal as in the room. Accordingly, a WPS (WiFi Positioning System) can be utilized to compensate the positioning of the GPS system.

The WiFi Positioning System (WPS) is a system in which a mobile terminal 100 uses a WiFi module included in the mobile terminal 100 and a wireless AP (wireless access point) transmitting or receiving a wireless signal with the WiFi module, Is a technology for tracking a location of a wireless local area network (WLAN) using WiFi.

The WiFi location tracking system may include a Wi-Fi location server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which certain wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP can transmit the location information request message to the Wi-Fi location server.

The Wi-Fi position location server extracts information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi position location server through the mobile terminal 100, or may be transmitted from the wireless AP to the Wi-Fi location server.

The information of the wireless AP to be extracted based on the location information request message of the mobile terminal 100 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 100 and extract the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. In this case, the information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, telephone number, and the like. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.

Then, the Wi-Fi location server can extract (or analyze) the location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 100.

As a method for extracting (or analyzing) the position information of the mobile terminal 100, a Cell-ID method, a fingerprint method, a triangulation method, and a landmark method can be utilized.

The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to previously convert the propagation characteristics into a database.

The triangulation method is a method of calculating the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. (Time of Arrival, ToA), Time Difference of Arrival (TDoA) in which a signal is transmitted, and the time difference between the wireless AP and the wireless AP, in order to measure the distance between the mobile terminal and the wireless AP. , An angle at which a signal is transmitted (Angle of Arrival, AoA), or the like.

The landmark method is a method of measuring the position of a mobile terminal using a landmark transmitter that knows the location.

Various algorithms can be utilized as a method for extracting (or analyzing) the location information of the mobile terminal.

The location information of the extracted mobile terminal 100 is transmitted to the mobile terminal 100 via the Wi-Fi location server, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 may be connected to at least one wireless AP to obtain location information. At this time, the number of wireless APs required to acquire the location information of the mobile terminal 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located.

And the fourth frequency band may be a band corresponding to the B4 reception band from 2110 MHz to 2155 MHz (or the fourth frequency band may be a band corresponding to the B66 reception band from 2110 MHz to 2200 MHz)

On the other hand, in the case of a mobile terminal, data is downloaded by a carrier aggregation method in which two or more reception bands are simultaneously opened. In this case, the reception band used varies depending on the area.

For example, in the case of a Korean operator or a Chinese operator, Carrier Aggregation of the B1 reception band and the B3 reception band is supported. On the other hand, in the case of the North American operator, the Carrier Aggregation of the B2 reception band and the B4 reception band It supports carrier aggregation.

In this case, the first filter 330 may filter the received signal to output the signal of the B1 band, and the third filter 350 may filter the received signal to output the signal of the B3 band.

Meanwhile, the second switch 370 can pass only the B1 band signal output from the first filter 330 to the first low noise amplifier 380, thereby amplifying the B1 band signal.

Also, the third switch 375 can pass only the signal of the B3 band outputted from the third filter 350 to the second low-noise amplifier 385, thereby amplifying the signal of the B3 band.

On the other hand, a case where a mobile communication service is provided by a North American provider that uses carrier aggregation of the B2 reception band and the B4 reception band will be described with reference to FIG.
