Hereinafter, a mobile terminal for releasing a screen lock through a new pattern input method and an operation method thereof according to an embodiment of the present invention will be described in detail.

FIG. 4 is a flowchart illustrating an operation method of a mobile terminal according to an embodiment of the present invention, and FIGS. 5 to 15 are referred to for explaining various examples of a method of operating the mobile terminal according to an embodiment of the present invention .

Referring to the drawings, first, the mobile terminal 100 accesses an access point (AP) (S410)

The access point 500 may perform a wired / wireless linked bridge function for relaying signals received from one station to another station. This access point can perform the same function as a bridge or switch of Ethernet.

Here, the station may be a portable terminal, a personal computer (PC), a TV, a VCR, a digital camera, an audio system, a content providing server, or an AP management server storing information on access points and content information.

Meanwhile, the station may be equipped with a network interface card. Examples of the wireless Internet technology include a wireless LAN (Wi-Fi), a wireless broadband (WIBRO), a wimax (World Interoperability for Microwave Access) And HSDPA (High Speed Downlink Packet Access). In addition, near-field communication technologies such as Bluetooth, Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), and ZigBee can be used.

Also, since the access point 500 includes the same physical layer and MAC layer as the mobile station 100, the access point 500 can basically perform the same operation as the station 100 . Thus, the access point may be considered the same as the station as needed.

The portable terminal 100 can search for an access point within a communicable range using a beacon or a probe message. The retrieval of the access point may be performed when receiving a user command requesting the retrieval of the access point or when the RSSI (Received Signal Strength Indication) value of the connected access point is less than the reference value.

The search method includes a passive scanning method in which the access point 500 periodically broadcasts a beacon message to the access point 500 and a method in which the mobile terminal 100 transmits a probe request for each channel, (Or broadcasts a message or a frame), receives a probe response message from the access point 500, and searches for the corresponding access point.

The probe response message includes various capabilities (speed, encryption, etc.) that the access point can support, an authentication key used when the access point authenticates when the access point is in open mode, an SSID (Service Set ID And a MAC address capable of identifying each access point.

The SSID can be referred to as a network identifier because it can identify the network to which the access point belongs, and the MAC address is an identifier of the access point because it can identify the access point. Other information may also be used to identify the network or access point in addition to the SSID or MAC address.

The portable terminal 100 accesses the searched access point 500 at step S410. Meanwhile, if necessary, the authentication process of the portable terminal 100 and / or the access point 500 may be performed.

Then, the portable terminal 100 stores access history information including identification information of the access point 500, location information, and connection use time information (S420)

Here, the identification information of the access point may include MAC address information, and more preferably, SSID information.

Each time the user connects to the Wi-Fi AP, the portable terminal 100 generates a connection use time (including a connection start time, a connection end time, etc.) including identification information such as a MAC address of a Wi- Information, location information such as GPS coordinates, and the like.

On the other hand, the portable terminal 100 updates the place analogy table including the identification information of the access point, the location information, and probability points allocated to a predetermined plurality of candidate locations based on the access history information (S430 )

According to an embodiment of the present invention, the update step (S430) may change the probability points by applying a weight based on the connection use time information.

Fig. 6 shows an example of the place analogy table. The place analogy table can be stored, managed, and displayed in a matrix form as shown in FIG.

The place analogy table may include an identification information item 610 and a location information item 620 of the AP. In FIG. 6, a MAC address is used as the identification information of the AP, and GPS coordinates are used as the location information.

In addition, the place analogy table may further include predefined candidate location items 630, 640, 650, and 660. The candidate location items 630, 640, 650, 660 may be added and changed. For example, as shown in FIG. 6, there are four candidate places such as home, school, restaurant, and other favorite places. On the other hand, in the case of student users, the school could be set as a candidate place on behalf of the company.

Meanwhile, the place analogy table stores values corresponding to the items 610, 620, 630, 640, 650, and 660 for each of a plurality of APs.

 Since the name information of the AP is not indispensable, the location analogy table may include corresponding location information 621, probability points 631, 641, and 642 for each candidate location based on the identification information 611 of any one of the APs, 651, 661) can be stored in association with each other.

Meanwhile, the mobile terminal 100 changes probability points 631, 641, 651, and 661 for each candidate location by applying a weight based on the connection use time information.

For example, when the user is frequently at home from 9:00 pm to 7:00 am, the weight of the "home" item can be weighted and the home weight can be increased according to the duration of the connection. Thus, the probability point may be changed to reflect the weight corresponding to the access time zone.

Meanwhile, the updating step (S430) may be performed periodically or at the end of the connection.

Meanwhile, a method of operating a mobile terminal according to an exemplary embodiment of the present invention may include matching a candidate location with a specific access point corresponding to a probability point having a value greater than a reference value among the probability points included in the updated place analogy table Step < / RTI >

 The mobile terminal 100 matches the location with the WIFI AP when the location probability reaches a preset threshold value or more.

For example, assuming that the reference value is 75, referring to FIG. 6, the GPS coordinates 622 of the second AP is "Company" because the probability point 642 of the candidate place company has reached 90, which is larger than the reference value 75 And the GPS coordinates of the third AP can be deduced to " restaurant " since the probability point 653 of the candidate location restaurant has reached 80, which is greater than the reference value 75. [

Another example is that the location of a particular AP is analogous to the home: 80, the company or school: 10, the restaurant: 20, the other favorite place: 25, and the reference value is 79 can do.

As described above, the place analogy operation of the present invention is performed based on time information and can be performed when the Wi-Fi connection is disconnected or on a periodic basis.

That is, the mobile terminal 100 regularly updates a probability point of each candidate location corresponding to each WIFI AP, and when the probability point is greater than or equal to a predetermined reference value, the location is matched with the WIFI AP You can save and manage.

Meanwhile, in the matching step S430, at least one of the stored text message, e-mail, calendar, and memo information is combined with the probability point to be matched. That is, it is possible to further improve the accuracy of the place analogy by taking various information into consideration.

The method of operating a portable terminal according to an exemplary embodiment of the present invention may further include matching a second level candidate location based on the access history information and the matched first level candidate location. In other words, the accuracy of the place analogy can be further improved by considering the information of the already-judged place and judging the judgment of the new place.

According to the present invention, the portable terminal 100 matches the candidate location with the access point (AP) through the place analogy operation, stores information matched to the database 160 of the memory 160 or another storage space, When a user uses a location-related service, this information can be called up to facilitate positioning.

FIG. 7 shows an example of information provided according to a predetermined category when using a location-related service in the future. In the example of FIG. 7, the information of the category of the address 711, the place 720, and the map 730 is provided to the user. The user can check or select information for each category. That is, it is possible to display the inferred place 721 together with the corresponding detailed address 711 and the map 731, so that the address can be inputted only by the user's touch.

The detailed address 711 and the map 731 can be secured through various means such as performing an additional Internet search or receiving from the service provider.

The demand for location-based applications and services has been steadily increasing since mobile terminals such as smart phones have supported the GPS function. Navigation, navigation around me, and the surrounding area are used by many users. When using these location-based services, the troublesome part is the address input part. It is very troublesome to designate this point as an important point when directly inputting the address of house, company, favorite restaurants, or the like.

Accordingly, the portable terminal 100 according to the embodiment of the present invention provides a function of extracting a meaningful place to the user by using the WIFI access point (AP) access history information.

In addition, the present invention analyzes the access history of a mobile phone WIFI AP to derive meaningful place, house, company, school, frequent restaurant, or place to user and obtain information about this point later, It is possible to improve the convenience in performing location based services such as a function to inform the user.

As described above, there is an advantage that the location-based service can be used even when the GPS function of the portable terminal is turned off as well as the location input and the location designation can be easily performed. Since the GPS function further increases the battery consumption of the portable terminal, the user can turn off the GPS function for a predetermined time. According to the present invention, when accessing the pre-registered AP or searching for an already registered AP, Information may be used to provide location-based services.

The location information of the access point may include GPS coordinates information received by the wireless Internet module or the GPS module. The portable terminal 100 may receive GPS coordinate information by the GPS module, or may receive the GPS coordinate information when the AP has its own location information or a separate server has location information through the wireless Internet module.

The location information of the access point may be information generated by combining location information sensed by a plurality of location units. Also, the location information of the access point may include at least one of coordinate information, latitude and longitude coordinates, address, building name, and mobile communication network information.

For example, the location information of another AP can be calculated using the size of RSSI (Received Signal Strength Intensity) signal received from an AP that already knows the location information. Or acquire cell information, base station information, and location information of the mobile communication network, or obtain location information using other communication means such as NFC. Or POI information such as coordinate information, address, and building name directly input by the user.

Each of these pieces of information may be combined with location information obtained by various other means to determine location information of a certain AP.

The location information can be determined by combining the information obtained by various means.

Meanwhile, the weight may be assigned to a plurality of time periods divided into 24 hours a day.

8 shows examples of weights 811, 812, 813, 814, 821, 822, 823, and 824 set for the time zones 831, 832, 833, and 834 of the candidate place 810 and the company 820 It is.

The portable terminal 100 may divide the 24 hours a day according to predetermined criteria such as 24 or 12 divisions, and assign a weight to each time zone.

8 illustrates a time zone of a nightclub where a user is likely to be at home mainly. The weights 821, 822, 823, and 824 assigned to the company 820 are weight values 811 and 812 , 813, 814).

Meanwhile, the time-based and time-based weights can be stored in the memory 160 or the control unit 180 and can be set and changed by the user.

The portable terminal 100 can deduce a place using time-based access time information based on the weight recorded in the table of FIG. For example, when you connect to AP 1 at 0-2, AP 1 increases the probability of inference point by 5 points, and increases the probability of company probability by 1 point.

Thus, if the probability inference point accumulated by the update exceeds the reference value, AP 1 can be designated as a specific place. If the reference value is 75 and the probabilistic inference point of AP1's candidate place is 75 or more, the position of AP1 can be matched to home.

Further, the weight may be given based on the day of the week. That is, each day of each day is divided into time zones, weights are given, and weights of the corresponding days are applied.

Alternatively, weights can be set based on weekdays, weekends, and holidays.

FIG. 9 (a) shows the weight given to weekdays and weekdays 930, and FIG. 9 (b) shows the weights given at weekends.

If a user is a worker at a company, there is a high probability of being in the company during the day on weekdays and at home in the nighttime. Therefore, in the case of the candidate place 910, the weights 911 and 914 corresponding to the night time zones 931 and 934 are set to values higher than the weights 912 and 913 corresponding to the daytime zones 932 and 933, respectively . Conversely, in the case of the candidate site company 920, the weights 921 and 924 corresponding to the night time zones 931 and 934 are set to values lower than the weights 922 and 923 corresponding to the daytime zones 932 and 933, respectively .

On the other hand, in the case of the weekend 970, various weights can be set according to the life pattern of the user. In the case of the candidate site 950, the weights 951 and 954 corresponding to the night time zones 971 and 974 may be set to values higher than the weights 952 and 953 corresponding to the daytime zones 972 and 973 .

On the other hand, in the case of the candidate site company 920, the weekly weight values 961, 962, 963, and 964 may be set to values lower than the same weekday weight values 921, 922, 923, and 924 on weekdays.

In another embodiment, only the weekly WIFI access information other than weekends and holidays on which the movement pattern is not constant may be used, the day may be divided into 24 hours, and a place weight may be assigned to each time zone.

Meanwhile, the method of operating the portable terminal according to the embodiment of the present invention may further include matching the second level candidate location based on the access history information and the matched first level candidate location.

In this case, the second level candidate location matching step may be characterized in that the access point connected to the same time zone as the first level candidate location designates a candidate location of the same kind, or the plurality of first level candidate locations And the second level candidate location is matched based on a pattern, a distance, and a route of the second level candidate.

Referring to FIG. 10, a MAC address 1010, GPS coordinates 1020, matching location 103 and access time information 1040 of the APs may be managed.

The AP having the predetermined candidate location matched to the first level may be designated as the second level through which the location analogy is not performed yet.

The portable terminal 100 refers to the identification information 1011 of the first level AP, the location information 1021, the first level candidate location 1031 matched and the connection use time information 1041, The first level candidate location 1031 and the connection use time information 1041 that are matched can be used to estimate the location of the AP at the second level where the location is not yet inferred or judged.

That is, if the connection use time information 1032 of the second-level AP is similar to the matched first-level connection use time information 1041, it can be designated as the same kind of candidate place, for example, , The identification information 1012 of the AP at the second level, and the GPS coordinates 1022, in association with each other.

Alternatively, after locating a place that is very important to the user, such as a house, a company or a school, and a place frequently appearing according to a repeated pattern, a meaningful place can be derived by using a user's route have.

11, after the positions of the first-level candidate place holder 1110 and the company 1120 are grasped, it is possible to grasp the way to go to / from the house 1110 and the company 1120. And can also be used to deduce the meaning of a place frequently visited around the house 1110 and the company 1120 as well as being able to use the work route and the work route 1130 itself as a meaningful place.

For example, using the first-level company location information that has already been identified, it is possible to deduce a frequently visited restaurant location at lunch time or evening time as a frequent restaurant location.

In addition, since a place frequently visited frequently by a user is likely to be located between a house and a company or nearby, the travel route information can be used to identify a place visited at a specific time periodically, such as a gymnasium.

Meanwhile, the method of operating the portable terminal according to the embodiment of the present invention may further include matching the specific access point with the candidate location based on at least one of stored text message, e-mail, calendar, and memo information have.

Information recorded in the portable terminal or information on available contents (e.g., texts or texts of SMS / mms), contents of e-mails, places or times entered in calendars, memo information, It can be further considered to determine a meaningful place by parsing a part of the information in the area.

For example, when the contents of the calendar contents 1210 of June 4 include the time information 1211 and the place information 1212 as shown in FIG. 12, the wireless terminal adds time information 1211 And location information 1212 can be combined to determine the location.

In addition, when the contents of the message body are related to time and location such as " I will go home at the evening time ", the time and place information can be used to deduce the place.

In addition, the locations searched using the map application can be categorized as a region of interest to the user and used for future analogy.

On the other hand, according to the embodiment, the mobile terminal 100 can display a screen for confirming the user as shown in Fig. 13 before registration of the matched place. And may provide information in the form of a place registration list 1410 that includes a plurality of determined AP information and place information.

15, 1520, 1520 and 1530 are searched for at the same time in accordance with the use of the wireless network and the increase of access points, the mobile terminals often search a plurality of APs 1510, 1520 and 1530, A more efficient management method is required.

Therefore, in the method of operating the portable terminal according to the embodiment of the present invention, a plurality of access points having the same SSID are managed as one representative access point in the place analogy table.

In this case, the representative access point may be the access point having the highest access frequency or the access time having the longest access time among the access points having the same SSID.

Alternatively, the method of operation of the portable terminal according to an embodiment of the present invention may be such that a plurality of access points located within a predetermined distance can be managed as one representative access point in the place analogy table, An access point having a highest connection frequency or a longer connection usage time than the plurality of access points located within the distance.

When receiving location information using a Wifi router, it extracts location information, such as GPS coordinates, at connection or disconnection. In this case, the access point having the same SSID is basically located at the same position, and managed by one representative access point. That is, each time a connection is made to an access point having the same SSID, the value of the place analogy table corresponding to the representative access point is accumulated and increased.

On the other hand, according to the embodiment, when the SSID information is different, it can be recognized as the same place when there is not a big difference from the position coordinates of the SSID already stored.

For example, suppose that the SSID of the newly connected AP is 'R & D Campus 2222' and the GPS coordinates are 10.000, 42.000, and 10.000, assuming that the SSID is 'R & D campus' 42.001), the SSID is different, but the difference in GPS coordinates is insignificant, so it can be recognized as the same place.

Alternatively, if the SSID is the same but the coverage of the SSID is too large, this information can be ignored or clustered into N areas and managed internally by itself.

According to the embodiment of the present invention, the location information of the user can be more accurately and conveniently provided using the access information to the access point.

In addition, it can be used for location-based services by deriving meaningful places for users.

As described above, the determined place information can be used in any application or service requiring a place input such as a calendar, a navigation, a traffic situation, and the like. In addition, by using the place information, it is possible to reduce the inconvenience of the process of inputting the place of the user.

Further, if the user recognizes a meaningful place, he can notify the user of the detailed information or surrounding information. For example, when the user knows the route to / from the work route, traffic information can be notified in real time, and information on special events such as discount events, opening events, etc. can be informed to the user in advance.

The portable terminal according to the present invention and its operation method are not limited to the configuration and method of the embodiments described above but the embodiments can be applied to all or a part of each embodiment Or may be selectively combined.

Meanwhile, the operation method of the portable terminal of the present invention can be implemented as a code that can be read by a processor in a recording medium readable by a processor included in the portable terminal. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium that can be read by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave such as transmission over the Internet . In addition, the processor-readable recording medium may be distributed over network-connected computer systems so that code readable by the processor in a distributed fashion can be stored and executed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
