Hereinafter, the configuration and operation of the mobile terminal 100 according to the present embodiment will be described with reference to FIG. 1 showing a configuration of a mobile terminal positioning system including a mobile terminal according to an embodiment of the present invention.

The mobile terminal 100 receives positioning data including data related to the position of the mobile terminal 100 from the positioning data providing apparatus 300 and extracts data related to the position of the mobile terminal 100 from the positioning data Generates positioning information, and transmits the positioning information to the positioning server 200.

2, the mobile terminal 100 may receive a GPS signal from the GPS satellite 300-3 at some locations, but may receive GPS signals from the GPS satellite 300-3 at some locations, such as indoors and underground It can generate the positioning information of the mobile terminal 100 using the signal received from the mobile communication base station 300-2 or the wireless LAN signal received from the AP (Access Point). The technique of generating positioning information of the mobile terminal 100 using the mobile communication base station signal is a technique called a so-called cell ID positioning positioning technique. The technique of positioning the mobile terminal 100 by the service cell ID positioning of the base station, (100). A technique for generating positioning information of the mobile terminal 100 using the wireless LAN signal is a so-called WPS (WIFI Positioning System), which identifies an AP currently connected to the mobile terminal 100 and uses the installation location of the AP And the position of the mobile terminal 100 is grasped. The cell ID positioning positioning technology and the technical data related to the WPS technology can be easily obtained through the Internet, a paper, etc., so that detailed description thereof will be omitted herein.

According to one embodiment, the mobile terminal 100 distinguishes between an outdoor mode and an indoor mode, generates positioning information using only the GPS signal in the outdoor mode, and uses the mobile communication base station signal and the wireless LAN signal Information can be generated. According to another embodiment, in addition to the GPS signal, at least one of the mobile communication base station signal and the WLAN signal may be further used in the outdoor mode to more precisely generate the positioning information.

The positioning server 200 receives the positioning information and services the location information of each mobile terminal 100. For example, the positioning server 200 can provide a search for missing persons, a search for missing persons, a lost mobile terminal search service, and the like. The positioning server 200 may be a server that simply records the location information of one or more mobile terminals 100 or may provide a Location-Based Service (LBS) using location information of one or more mobile terminals 100 Lt; / RTI > In the positioning server 200, however, the name "server" is given based only on the server-client relationship with respect to the mobile terminal 100, and is not limited to the shape and installation location of the apparatus.

The mobile terminal 100 may be a computer having a wireless LAN interface, an Ultra Mobile PC (UMPC), a workstation, a netbook, a PDA (Personal Digital Assistant), a portable computer, a web tablet, A wireless phone, a mobile phone, a smart phone, a child mobile phone, an e-book, a portable multimedia player (PMP), a portable game machine, a navigation device A black box, a digital camera, a 3-dimensional television, a digital audio recorder, a digital audio player, a digital picture recorder ), A digital picture player, a digital video recorder, a digital video player, a device capable of transmitting and receiving information in a wireless environment, Ha , It may be an electronic device such as one of various electronic devices that make up a computer network, one of various electronic devices constituting a telematics network, or any of a variety of components that make up the computing system.

Hereinafter, the configuration of the mobile terminal 100 shown in FIG. 1 will be described. 1, the mobile terminal 100 according to the present embodiment is configured to power on the configuration parts of the positioning report unit 102, the motion detection sensor 104, the control unit 106, and the mobile terminal 100 And a battery 108 for supplying power.

First, the motion detection sensor 104 is a sensor for detecting movement of the mobile terminal 100, and may be an acceleration sensor, a gravity sensor, or a gyro (angular velocity) sensor. The motion detection sensor 104 may be a combination of two or more of an acceleration sensor, a gravity sensor, and a gyro sensor. In addition, when the motion of the mobile terminal 100 can be detected by analyzing an image captured by the camera module included in the mobile terminal 100, the motion sensor 104 may indicate the camera module.

Next, the positioning reporting unit 102 repeatedly performs one of the first positioning reporting process or the second positioning reporting process at predetermined positioning cycles. Wherein the first positioning reporting process is a process including receiving positioning data, generating positioning information through analysis of the positioning data, and transmitting the positioning information to a positioning server, And a step of retransmitting the positioning information to the positioning server. The second positioning report process is a process that can save the power consumption required for receiving positioning data and generating positioning information while transmitting positioning information to the positioning server at regular intervals.

The control unit 106 controls the positioning reporting unit 102 to perform the first positioning reporting process when the motion is detected by the motion sensing sensor 104 within one positioning period, 102 to perform the second positioning reporting process. That is, when the motion detection sensor 104 has measured the movement of the mobile terminal 100 during one positioning period, the control unit 106 causes the positioning reporting unit 102 to receive the positioning data again, If the motion detection sensor 104 has not measured the movement of the mobile terminal 100 during one positioning period, the positioning information reported immediately before is reported back to the positioning server 200 .

According to one embodiment, the control unit 106 controls the motion detection sensor 104 to determine whether movement has been measured by the motion detection sensor 104 within the positioning period after one positioning period has passed, It is possible to confirm whether the power is on or off. At this time, the motion detection sensor 104 is powered on when the positioning period starts, and is powered off when it detects movement during the positioning period. Therefore, if the motion detection sensor 104 is in the power-off state at one time of the positioning cycle, there is at least one movement of the mobile terminal within the positioning cycle. Likewise, if the motion detection sensor 104 is in the power-on state at a point in time of one positioning period, the mobile terminal has never been moved within the positioning period. If the motion sensing sensor 104 senses the movement of the mobile terminal 100 within one positioning period, the motion sensing sensor 104 does not need to operate for at least the period. Therefore, the mobile terminal 100 of the present embodiment has an effect of reducing power consumption required for the operation of the motion detection sensor 104 by being powered off immediately after the motion detection sensor 104 detects motion. On the other hand, according to another embodiment, the motion detection sensor 104 may be powered off when two or more specified motions are detected during one positioning period.

The mobile terminal 100 according to the present embodiment reports periodically the positioning information transmitted immediately before without performing the separate positioning data reception when there is no movement of the mobile terminal 100, Battery consumption due to data reception can be prevented.

In this regard, the operation of the mobile terminal 100 according to the present embodiment will be described in more detail with reference to FIG. 3, the positioning reporting unit 102 is provided with the positioning data receiving module 122 only when the positioning reporting process is designated from the control unit 106 and specified to perform the first positioning reporting process, A positioning data receiving module 122 for receiving positioning data via the communication module 128, a positioning data receiving module 122 for receiving the positioning data from the positioning data receiving module 122, A positioning information generation module 124 that generates positioning information that can be recognized by the positioning server 200 and a positioning information reporting module 126 that reports (transmits) the positioning information to the positioning server 200 through the communication module 128 .

The positioning information reporting module 126 may include a buffer 1260 for temporarily storing positioning information reported to the positioning server 200. [ The positioning information reporting module 126 re-reports (retransmits) the previous report positioning information stored in the buffer 1260 to the positioning server 200 when the control signal receiving module 120 is requested to perform the second positioning reporting process, can do.

The mobile terminal 100 according to the present embodiment can operate in one of the outdoor mode and the indoor mode, have. According to an exemplary embodiment, the mobile terminal 100 may receive only the GPS signal in the outdoor mode, and receive at least one of the wireless LAN signal and the mobile communication base station signal in the indoor mode. According to another embodiment, the mobile terminal 100 further receives at least one of the wireless LAN signal and the mobile communication base station signal as well as the GPS signal in the outdoor mode, and transmits the wireless LAN signal and the mobile communication base station signal At least one can be received.

The mobile terminal 100 according to the present embodiment can designate the positioning data to be received according to the same mode as the operation mode of the previous positioning period. For example, if the GPS signal and the mobile communication base station signal are received according to the outdoor mode in the previous positioning period, the GPS signal and the mobile communication base station signal are also received in this positioning period. To this end, as shown in FIG. 4, the positioning data receiving module 122 may further include a buffer 1220 for storing a value indicating an operation mode of the previous positioning period.

There may be a case where the mobile terminal 100 is located indoors in the previous positioning period according to the movement of the mobile terminal 100 and the mobile terminal 100 is located outdoors in this positioning period or vice versa will be. Hereinafter, the operation of the mobile terminal 100 according to the present embodiment will be described when the operation mode change of the mobile terminal 100 is required.

First, when the mobile terminal 100 is located outdoors in the previous positioning period and moves to the room in this positioning period, the positioning data receiving module 122 tries to receive the GPS signal through the communication module 128 but fails will be. In this case, the positioning data reception module 122 switches the operation mode to the outdoor mode, and receives the positioning data again through the communication module 128. That is, the GPS signal receives the wireless LAN signal or the mobile communication base station signal instead. In addition, the buffer 1220 stores a value indicating an outdoor mode. In the next positioning period, the positioning data receiving module 122 will operate in the indoor mode with reference to the value recorded in the buffer 1220. [

In the case where the mobile terminal 100 is located indoors in the previous positioning period and moves outdoors in this positioning period, it may fail to receive the positioning data according to the indoor mode, Changes to the list of strength or signaling devices may occur.

That is, when the positioning data receiving module 122 fails to receive the positioning data in the indoor mode, the positioning data receiving module 122 may attempt to receive the positioning data according to the outdoor mode by switching the operation mode to the outdoor mode. The positioning data receiving module 122 may also be configured to receive the positioning data when the at least one of the following conditions is satisfied: i) the signal strength changes more than the reference value from the signal strength in the immediately preceding cycle, and ii) It is possible to switch to the outdoor mode and try to receive the positioning data according to the outdoor mode. For example, although the signal of the AP installed indoors may be received outdoors, the intensity of the signal may be changed by more than a reference value. In addition, APs that transmit wireless LAN signals when located indoors and outdoors may be different. In addition, if the signal strength of the mobile communication base station or the base station ID is changed, it can be assumed that the mobile station has moved from the room to the outside.

The positioning data receiving module 122 stores the signal strength of the positioning data received in the indoor mode and the list of the signal transmitting apparatuses in the buffer 1220 so that they can be referred to in the next cycle.

In summary, in the event that the positioning data receiving module 122 switches the operation mode from the indoor mode to the outdoor mode, the first event that fails to receive the positioning data according to the indoor mode, There may be a second event in which the signal strength in the previous cycle is changed from a signal strength more than a reference value, and a third event in the list of the signal transmitting apparatus. The positioning data reception module 122 may be configured to switch the operation mode from the indoor mode to the outdoor mode when at least one event of the first to third events occurs.

Up to this point, each of the components of FIGS. 1, 3 and 4 may refer to software or hardware such as a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). However, the components are not limited to software or hardware, and may be configured to be in an addressable storage medium and configured to execute one or more processors. The functions provided in the components may be implemented by a more detailed component or may be implemented by a single component that performs a specific function by combining a plurality of components.

Hereinafter, a positioning method of a mobile station according to another embodiment of the present invention will be described with reference to FIG. 5 to FIG. The positioning method of the mobile terminal according to the present embodiment can also be understood as a method performed by the mobile terminal 100 shown in FIG.

First, referring to FIG.

5, the positioning method of the mobile terminal according to the present embodiment includes positioning data reception (S100), positioning information generation (S102), positioning information report (S104) and one positioning period (S106), it is repeated to determine whether the motion has been measured within the positioning cycle (S108). If the motion detection sensor of the mobile terminal senses the movement of the mobile terminal within the positioning period after one positioning period has elapsed, the positioning information generated using the received positioning data will be reported If the motion detection sensor of the mobile terminal has not detected the movement of the mobile terminal within the positioning period, it is determined that the mobile terminal has not moved, so that the previously reported positioning information is re-reported.

Receiving the positioning data (S100) means receiving different kinds of positioning data according to the operation mode. For example, when the operation mode is an outdoor mode, it may mean receiving a GPS signal. According to an exemplary embodiment, when the operation mode is an outdoor mode, not only a GPS signal but also a mobile communication base station signal may be received. Also, when the operation mode is the indoor mode, the wireless LAN signal and the mobile communication base station signal may be received.

In addition, generating the positioning information (S102) may mean generating information of a form recognizable by the positioning server from the received positioning data. For example, the reception result of the mobile communication base station signal may be processed and transmitted to the positioning server in a predetermined format according to the positioning method based on the mobile communication base station signal such as the cell ID positioning method. In addition, the reception result of the wireless LAN signal can be processed in a predetermined format according to a positioning method based on a wireless LAN signal such as a WIFI (WIFI Positioning System), and transmitted to the positioning server.

FIG. 6 is a flowchart of a positioning method of a mobile terminal in which the flowchart shown in FIG. 5 is partially modified. As shown in FIG. 6, the motion sensor of the mobile terminal may be powered on (S105) before the start of the positioning period and may be powered off (S162) after the motion measurement (S160) within the positioning period. Therefore, it can be determined whether the mobile terminal has moved within the positioning period by checking whether the motion detection sensor is in the power-off state after the positioning period has elapsed.

As described above, in the positioning method of the mobile station according to the present embodiment, it is a principle that the operation mode (outdoor / indoor) of the previous cycle is maintained as it is in this cycle. However, if the mobile terminal has moved between indoor / Can be accomplished. This will be described with reference to FIGS. 7 to 8. FIG. 7 to 8 are detailed flow charts of the positioning data reception step S100.

First, the operation mode is checked to select the reception object positioning data (S1000). Assuming that the operation mode is initialized to the outdoor mode, GPS data reception will be attempted in the first positioning cycle (S1002). If the reception of the GPS signal is successful (S1004), the operation mode is kept in the outdoor mode, and the positioning data reception step S100 is ended.

However, if the reception of the GPS signal fails (S1004), the operation mode is switched to the indoor mode so that the WIFI signal (wireless LAN signal) is received (S1008).

Meanwhile, when the operation mode is the indoor mode, an operation of comparing the wireless LAN signal received this time with the wireless LAN signal received in the previous cycle is performed (S1012). As a result, if the list of APs or the intensity of a signal transmitted by each AP is changed by more than the reference value, the operation mode is switched to the outdoor mode (S1016). When the positioning of the next period is performed, Lt; / RTI >

In addition, according to one embodiment, when there is no AP transmitting the wireless LAN signal, the operation mode may be switched to the outdoor mode (S1016). 7, the mobile communication base station based positioning data reception shown in FIG. 8 may be attempted without switching the operation mode to the outdoor mode even if there is no AP transmitting the wireless LAN signal.

That is, in the positioning method according to the present embodiment, when at least one of the positioning data to be received in the indoor mode is not received, the operation mode may be switched from the indoor mode to the outdoor mode, The positioning report can be performed by receiving other positioning data even if it is not received.

If there is an AP transmitting a wireless LAN signal (S1010), and if the list of APs or the strength of a signal transmitted by each AP is not changed by more than a reference value as compared with the previous period, (S1014), and positioning data reception step S100 ends.

As shown in Fig. 8, the cell ID positioning technique may be used in the indoor mode. In this case, when the indoor mode is the result of the operation mode check (S1000), the mobile communication base station signal is received (S1009). In FIG. 8, it is assumed that there is no communication shadow area in which the mobile communication base station signal is not received in the room. However, in order to determine the movement outdoors in the room using the cell ID positioning technique, the received signal strength and the received signal strength (RSSI) and the cell ID of the immediately preceding cycle can be compared with each other (S1013) . Since the movement in the room does not cause a change in signal intensity or a change in the cell ID beyond a certain reference value, if there is a change in the reference value or more as a result of the comparison (S1013), the operation mode is changed to the outdoor mode, (S1017). Otherwise, the cell ID and the signal strength value of the mobile communication base station signal received in this positioning period are backed up for comparison with the received signal strength and the cell ID in the next positioning period (S1015).

Hereinafter, a mobile terminal and a positioning method according to another embodiment of the present invention will be described with reference to FIGS.

The configuration of the mobile terminal 400 shown in FIG. 9 is the same as that of the mobile terminal 100 shown in FIG. However, in the operation mode, the control unit 406 of the mobile terminal 400 shown in FIG. 9 does not instruct the positioning report unit 402 to report the positioning information according to a certain positioning period. The control unit 406 instructs the positioning report unit 402 to transmit the positioning information only when the motion detection sensor 404 detects the motion and transmits the motion detection trigger signal to the control unit 406. [ The operation of each component of the mobile terminal 400 will be described below.

The positioning reporting unit 402 receives the positioning data, analyzes the positioning data, generates positioning information, and transmits the positioning information to the positioning server. The positioning reporting unit 402 does not operate when the operation mode of the mobile terminal 400 is the power saving mode. The positioning reporting unit 402 receives the positioning data only when the operation mode of the mobile terminal 400 is the normal mode and reports the positioning information.

The motion detection sensor 404 senses the motion of the mobile terminal 400 and transmits a motion detection trigger signal to the controller 406.

The control unit 406 immediately switches the operation mode to the power saving mode when the positioning report of the positioning report unit 402 is completed and when the motion is measured by the motion sensing sensor 404 in the power saving mode, So that the positioning reporting unit 402 can report the positioning information.

That is, since the mobile terminal 400 according to the present embodiment does not perform the positioning information reporting operation at all when there is no movement, the battery consumption can be further reduced as compared with the periodical positioning information reporting method.

According to one embodiment, when the remaining amount of the battery 408 included in the mobile terminal 400 is equal to or less than a predetermined first reference value, the controller 406 controls the motion detection sensor 404 and the motion detection sensor 404), interruption of power supply to all the parts except for the handling circuit of the interruption occurring in the movement measurement of the interruption circuit (404) can further save battery consumption.

The controller 406 may control the motion of the mobile terminal 400 by the motion detection sensor 404 when the remaining amount of the battery 408 provided in the mobile terminal 400 is equal to or smaller than a predetermined second reference value smaller than the first reference value. Even if the motion is not measured, the operation mode is switched to the normal mode, so that the last positioning information report can be performed before the mobile terminal 400 is powered off. At this time, the second reference value is obtained by receiving the positioning data of the positioning and reporting section, generating the positioning information by analyzing the positioning data, reporting the positioning information to the positioning server, . ≪ / RTI >

Hereinafter, a positioning method of the mobile terminal, which can be performed by the mobile terminal 400 shown in FIG. 9, will be described with reference to FIG.

As shown in Fig. 10, the positioning method of the mobile station according to the present embodiment is characterized in that, in the normal mode, positioning data reception (S200), positioning information generation (S202), positioning information report (S204) Mode (S206).

Switching from the power saving mode to the normal mode again (S210) is limited to the case where the motion detection sensor of the mobile terminal 400 measures the movement of the mobile terminal 400.
