Prior to the description, the location-based information to be described later may include various information related to its own location generated using location information including coordinate information and the like.

In particular, the location-based information may include at least one of administrative address information, point of interest (POI) information, setting name information, and relative location information. Of course, the location-based information may be location information itself including coordinate information and the like.

The administrative address information is hierarchically classified into a major classification zone (e.g., a country) / a first subdivision zone (province, state or metropolitan area) / a second subdivision zone (a city, a district or a county) .... a first subdivision zone ( It may consist of a town, town, town or village) / second sub-division (trough, street or building name). For example, administrative address information may be selectively generated from the major classification zone to the minor classification zone. In this case, location information for each administrative address information (particularly, coordinate information) may be pre-stored in the memory 160 or may be received from the outside through the wireless communication unit 110.

The POI information may mean name or specific information set for a specific place. For example, the POI information may include names such as "Oh Mart," "Oo Restaurant," "Oo Department Store," or other unusual information such as "Gyeonggi-do Restaurant," "Recommended Data Place," and "Weekend Outing Place." Can be. In this case, the position information for each POI information (particularly, coordinate information) may be pre-stored in the memory 160 or may be received from the outside through the wireless communication unit 110.

The setting name information may mean name or specific information set by a user with respect to a specific place. For example, the setting name information may include "where we met yesterday", "first date", "restaurant", "company", "house", "school" and the like. In this case, the position information for each set name information (particularly, coordinate information) may be pre-stored in the memory 160 or received from the outside through the wireless communication unit 110.

The relative position information may be information based on a movement pattern such as a movement distance, a movement time, a movement speed, a movement direction from one point to another point, or a distance based on a specific point (for example, the position of a specific mobile terminal). The information may mean information based on a relative position such as speed or direction of movement. In this case, the location information (particularly, coordinate information) of the specific mobile terminal may be pre-stored in the memory 160 or may be received from the outside through the wireless communication unit 110.

In addition, the resolution to be described later may mean a rating according to the degree of detail of the location-based information to be provided in providing its location-based information to the counterpart terminal. Alternatively, resolution may mean a rating according to the degree of detail of location based information to be displayed in displaying location based information of another terminal. In addition, the first terminal may set a resolution for each of the plurality of other terminals or in common with at least one other terminal corresponding to a specific condition (for example, within the same group, within a predetermined radius, etc.).

- First Embodiment -

Hereinafter, according to an embodiment of the present invention, a hierarchical generation method of location-based information and a method of providing location-based information according to the above-described resolution will be described with reference to the drawings. For convenience of description, it is assumed that the mobile terminal described below may optionally include the components shown in FIG. 1.

First, a hierarchical generation method of location-based information according to resolution will be described in more detail with reference to FIGS. 8 to 9F. Hereinafter, a mobile terminal that generates / provides location based information is referred to as a “first terminal” and another mobile terminal provided with location based information is referred to as a “second terminal”.

8 is a flowchart illustrating a process of generating and providing location based information in a first terminal.

As shown in FIG. 8, the first terminal receives location information using the wireless communication unit 110 (S810).

In a reception step S810, the first terminal may receive location information by at least one of a broadcasting system, a mobile communication system, a data communication system, a short range communication system, and a GPS system.

For example, the first terminal uses the broadcast receiving module 111 in the case of a broadcast system, the mobile communication module 112 in the case of a mobile communication system, and the wireless Internet module 113 in the case of a data communication system. In the case of the short range communication system, the short range communication module 114 and the location information module 115 by the GPS system may be used.

Here, the location information is information indicating a location of the first terminal, and may include coordinate information expressed by latitude, longitude, altitude, speed, time, and the like.

In addition, the receiving step S810 may be performed periodically, when the location information is updated, or when there is a request by the location information providing server or the first terminal.

In addition, the controller 180 may receive a location information reception notification signal from the wireless communication unit 110 when the location information is received. Alternatively, the controller 180 may monitor the reception of the position information by the wireless communication unit 110 periodically or at all times. Accordingly, the controller 180 may detect that location information has been received by the wireless communication unit 110.

In addition, the location information received in the reception step S810 may be stored in the memory 160.

The first terminal sets location based information using the location information received in the reception step S810 (S820). In this case, the first terminal may pre-store the reference information necessary for generating location-based information in the memory 160 or may receive it from the outside through the wireless communication unit 110. In addition, the setting operation of the location-based information may be performed by the controller 180 or by the location information module 115 according to a control signal of the controller 180.

For example, the first terminal, after grasping the coordinate information received in the receiving step (S810), as reference information necessary for generating location-based information, administrative address information, POI information, setting name information, or coordinate information for each relative location information. Coordinate information that matches the identified coordinate information is retrieved. The first terminal may set, as location-based information, administrative address information, POI information, setting name information, or relative location information corresponding to coordinate information matched with the identified coordinate information.

In the setting step S820, the first terminal may set location-based information hierarchically to correspond to a resolution set for the second terminal. Of course, there may be a plurality of second terminals. Here, the set resolution and location based information may be stored in the memory 160. On the other hand, when the resolution level is set highest for the second terminal, the first terminal may set the coordinate information itself as location-based information.

Hereinafter, the resolution setting by the first terminal will be described in detail. The condition of the resolution setting may be selected by the user or arbitrarily selected by the first terminal. For convenience of explanation, it is assumed that the resolution is set from the first grade to the tenth grade, and sets detailed location-based information from the first grade to the tenth grade. On the contrary, detailed location-based information may be set from the tenth grade to the first grade. In addition, the resolution level may be changed by user operation or may be changed from time to time according to the position of the second terminal.

First, the first terminal may set a resolution with respect to the second terminal according to the positional association degree between the first terminal and the second terminal.

For example, the first terminal may set a higher grade resolution as the location association between the second terminal and the second terminal is higher (eg, the smaller the classification of a matching administrative area is). In other words, if the "countries and provinces" match than the "country" only match the location is higher. Of course, the lower the position association, the higher the resolution resolution may be set.

9A to 9F, a resolution setting according to a location association based on administrative address information may be described in more detail. For convenience of explanation, it is assumed that the higher the position correlation is, the higher the resolution is set.

According to FIG. 9A, when the second terminal is located in a country different from itself, the first terminal may set the first class having the lowest level of detail of the location-based information provided.

Alternatively, according to FIG. 9B, when the second terminal is located in the same country or a different province (including metropolitan or metropolitan city) as the second terminal, the second terminal has the second lowest level of detail of the location-based information provided. Can be set.

Alternatively, according to FIG. 9C, when the second terminal is located in the same country / state / city or different district as the second terminal, the first terminal may set a third grade having the third lowest level of detail of the location-based information provided. have.

Or, according to Figure 9d, the first terminal, if the second terminal is located in the same country / state / city / district or a different dong, the fourth level of the fourth lowest degree of detail of the location-based information provided Can be set.

Alternatively, according to FIG. 9E, when the second terminal has the same country / state / city / gu / dong or concrete address information (eg, a building name) that is the same as that of the second terminal, The fifth lowest level of detail can be set.

Alternatively, according to FIG. 9F, when the second terminal matches up with the country / province / city / gu / dong and specific address information of the second terminal, the first terminal has a tenth grade having the highest level of detail of the location-based information provided. Can be set.

In addition, although not shown in the drawing, the first terminal may set the resolution according to the position association degree based on the distance to the second terminal.

For example, as the second terminal is located closer to the second terminal, the location-based information provided for the second terminal may set a resolution of a detailed level. On the other hand, on the contrary, the farther away from the self, the location-based information provided may set the resolution of the detailed level.

Next, the first terminal may set the resolution for the second terminal according to the familiarity (described later) set in the second terminal. Here, the intimacy may be automatically set in consideration of the degree of call / message transmission and reception between the first terminal device and the second terminal, or may be directly designated by the user.

For example, the first terminal, the higher the familiarity set for the second terminal, the location-based information provided for the second terminal can set the resolution of the detailed level. On the other hand, on the other hand, the lower the intimacy, the more location-based information provided may set the resolution of the detailed level.

Next, the first terminal may set a resolution directly input by the user as a resolution for the second terminal. Of course, when at least one second terminal is managed for each group, resolution may be set for each group.

Hereinafter, a process of generating location-based information hierarchically according to a resolution set for the second terminal by the first terminal will be described in detail.

Here, hierarchical generation of location-based information adjusts the degree of providing location-based information (when transmitting location-based information to a second terminal) or display (when receiving location-based information from a second terminal) to correspond to a resolution. It can mean to create.

In the following description, the location-based information is limited to the administrative address information. For convenience of explanation, it is assumed that the higher the resolution level, the more detailed administrative address information is generated. Thus, administrative address information may be generated hierarchically according to the resolution level.

For example, if the entire administrative address information that can be generated using the location information of the first terminal is "Shinil Apartment 10-dong 1004, Yuljeon-dong, Jangan-gu, Suwon-si, Gyeonggi-do, Korea," the location-based location is generated to correspond to the resolution of the second terminal. The information may be as shown in Table 1.

Resolution Administrative Address Information Grade 1 Do not provide 2nd class Republic of Korea 3rd class Gyeonggi-do, South Korea 4th grade Suwon, Gyeonggi-do, Korea 5th grade Jangan-gu, Suwon-si, Gyeonggi-do, Korea 6th grade Yuljeon-dong, Jangan-gu, Suwon-si, Gyeonggi-do, Korea 7th grade Sinil Apartment, Yuljeon-dong, Jangan-gu, Suwon-si, Gyeonggi-do, Korea 8th grade 10 Sinil Apartments, Yuljeon-dong, Jangan-gu, Suwon-si, Gyeonggi-do, Korea 9th grade # 1004, Sinil Apartment, 10, Yuljeon-dong, Jangan-gu, Suwon-si, Gyeonggi-do, Korea 10th grade Coordinate information

Meanwhile, when the location-based information of the second terminal is received, the first terminal may hierarchically generate the location-based information of the second terminal to be displayed according to the resolution set for the second terminal according to Table 1. . For example, if the location-based information of the second terminal is "Yeoksam-dong, Gangnam-gu, Seoul, Korea" and the resolution 3 class is set for the second terminal, the first terminal may be displayed as "location-based information of the second terminal to display." Seoul Metropolitan Government ".

Alternatively, for example, a time point (based on a distance of the second terminal from the first terminal) and an update period for providing location-based information according to the resolution of the second terminal may be shown in Table 2. Resolution-specific distances and update periods may be set individually.

Resolution Street Renewal cycle Grade 1 Within 100m radius 5 hours 2nd class Within 500m radius 3 hours 3rd class Within 1km radius 2 hours 4th grade Within 5km radius 1 hours 5th grade Within 10 km radius 30 minutes 6th grade Within 20 km radius 20 minutes 7th grade Within 50km radius 10 minutes 8th grade Within 100km radius 5 minutes 9th grade Within 500 km radius 1 minute 10th grade Within all radius real time

As shown in Table 1 and Table 2, 10 second terminals corresponding to each of the first to the tenth class are selectively set or the first to the tenth class exist for one second terminal. You may assume.

In operation S830, the first terminal transmits location-based information hierarchically generated by the controller 180 or the location information module 115 to the second terminal through the wireless communication unit 110.

As described above in the reception step S810, the first terminal uses the broadcast reception module 111 in the case of a broadcast system, the mobile communication module 112 in the case of a mobile communication system, and the radio in the case of a data communication system. The Internet module 113 may transmit location-based information to the second terminal using the local area communication module 114 by the local area communication system and the location information module 115 by the GPS system.

In addition, the transmitting step (S830) may be performed when the registration request of the location information providing service to the second terminal. This will be described in detail below.

Alternatively, the transmitting step S830 may be performed when the second terminal is connected to the location information providing service. This will also be described in detail below.

Hereinafter, a method of providing location information when registering a location information providing service will be described with reference to FIGS. 10 to 14D. Here, registration may mean registration as a terminal for transmitting / receiving mutual location information through a location information providing service or a registration in a location information providing service.

10 is a flowchart illustrating a registration process of a location information providing service in a first terminal.

As shown in FIG. 10, the first terminal stores identification information about the first terminal (S1010).

In the storing step S1010, the first terminal may store its identification information in the memory 160 or register and store it in the server.

Here, the identification information is information for identifying the first terminal or the first terminal user in using the location information providing service, and includes a terminal serial number and an international mobile equipement identity; IMEI '), a user ID and password subscribed to the location information providing service, a name registered to the location information providing service, a terminal phone number, a subscriber email address, and a subscriber homepage address. Therefore, the server may authenticate the authority to use the location information providing service of the first terminal by using the identification information about the first terminal. Alternatively, the other terminal may identify that the first terminal has requested the location information providing service to the first terminal using identification information about the first terminal received from the first terminal or the server.

The first terminal requests registration of the location information providing service to the second terminal through the wireless communication unit 110 (S1020). For example, in the case of the mobile communication module 112, the registration request may be performed using a messaging service such as a short message service (SMS) or a multimedia messaging system (MMS). Of course, the request step (S1020), as well as the above-described messaging service, can be performed using any system that can transmit and receive data between the terminals.

The first terminal may perform the request step S1020 through the server, or may perform the request step S1020 with respect to the second terminal immediately without going through the server. In some cases, even if registration is not requested by the first terminal, registration of the location information providing service may be requested to at least one terminal arbitrarily selected by the server. In this case, the registration request process by the first terminal may not be necessary.

In the request step (S1020), identification information or location based information on the first terminal may be transmitted to the second terminal. This is to inform the second terminal of the terminal requesting the location information providing service and its location.

Prior to performing the request step S1020, the first terminal may hierarchically generate location-based information to be transmitted in the request step S1020 according to a resolution set for the second terminal that is the target of the registration request.

Alternatively, prior to the execution of the request step S1020, the first terminal designates the type and the degree of providing the identification information or the location-based information to be transmitted in the request step S1020 among the entire identification information or the location-based information related to the first terminal. Can be.

Alternatively, the degree of providing location-based information may be different according to the familiarity set for the second terminal. For example, if the intimacy is high, the coordinate information (which is the basic information for generating all the above-described location information) can be transmitted as it is, but if the intimacy is low, the distance information (for example, the first terminal is Only within a radius of 5 km of the second terminal).

When the registration of the location information providing service is approved by the second terminal, the first terminal registers the second terminal as a target terminal of the location information providing service (S1030 and S1040).

The first terminal may be provided with whether the registration of the location information providing service has been approved by the second terminal from the server or the second terminal through the wireless communication unit 110. When the registration of the location information providing service is approved by the second terminal, the first terminal, the second terminal, or the server may register the first and second terminals as target terminals of the location information providing service. The target terminal information of the location information providing service may be stored in the memory 160 of the first and second terminals or may be stored and managed in a server.

11 is a flowchart illustrating a registration process of a location information providing service in a second terminal.

As illustrated in FIG. 11, the second terminal receives a request for registration of a location information providing service from the first terminal or the server through the wireless communication unit 110 (S1110).

In operation S1120, the second terminal receives identification information or location-based information about the first terminal from the first terminal or the server.

The request and reception steps S1110 and S1120 may be performed by using a messaging service such as SMS or MMS. Of course, the request and reception step (S1110, S1120), as well as the above-described messaging service, can be performed using any system that can transmit and receive data between the terminals.

When the registration of the location information providing service is approved by the second terminal, the second terminal is registered as a target terminal of the location information providing service of the first terminal (S1130 and S1140). In this case, the first terminal, the second terminal, or the server may register the first and second terminals as target terminals of the location information providing service.

12 is a state diagram of a first embodiment showing a registration process of a location information providing service.

As illustrated in FIG. 12, the first terminal may select at least one target terminal to request registration of a location information providing service according to a user's selection. Here, the user can directly input the telephone number of the target terminal, or select the target terminal by searching the telephone number stored in the telephone book or a name set therein. Alternatively, the user may select at least one terminal in which a resolution level of a certain level or more (or less) is set.

In FIG. 12, the first terminal requests registration of the location information providing service to terminals corresponding to "011-111-1111", "Pullback", and "Hee-hee".

13A to 13D are state diagrams illustrating a registration process of a location information providing service.

As shown in FIG. 13A, the first terminal displays a phrase asking whether to request registration of a location information providing service on a screen (a).

When the request ("Yes") is selected in the state (a), the first terminal displays a list of selection conditions of the terminal (hereinafter, 'registration request terminal') requesting registration of the location information providing service (b).

The selection condition list displayed in the state (b) may include a street, a place, a phone book, and a street / place / phone book.

When the distance is selected from the selection condition list, the first terminal may display the screen illustrated in FIG. 13B. As shown in FIG. 13B, the first terminal may select terminals located within a predetermined radius from the first terminal as a registration request terminal. Here, the predetermined distance may be input directly by the user using the numeric keys or the direction keys, or may be selected and input from a list consisting of settable radii.

In addition, when a place is selected from the selection condition list, the first terminal may display the screen illustrated in FIG. 13C. As illustrated in FIG. 13C, the first terminal may select terminals located at a specific place as a registration request terminal. Here, the user may directly input a specific place (eg, “Gangnam Station Exit 7”) through an input window, or may select and input from a place list.

In addition, when the phone book is selected from the selection condition list, the first terminal may display the screen shown in FIG. 13D. As shown in (a) of FIG. 13D, the first terminal may select, as a registration request terminal, a terminal corresponding to each of at least one selected name from a list of names registered in telephone numbers stored in the first terminal. . Alternatively, as illustrated in (b) of FIG. 13D, when the phone numbers stored in the first terminal are managed for each group, the first terminal may include at least one selected from a list of names set in phone numbers belonging to a specific group. A terminal corresponding to each name may be selected as a registration request terminal.

14A to 14C are state diagrams illustrating a registration process of a location information providing service.

As shown in FIG. 14A, when the second terminal receives a registration request for the location information providing service from the first terminal, the second terminal may display identification information of the first terminal, for example, a display of the telephone number "019-123-4567". Together with "019-123-4567" is displayed that the request to register the location information providing service.

Alternatively, as illustrated in FIG. 14B, when the second terminal receives a registration request for the location information providing service from the first terminal, if the second terminal stores "Yoon Ho" as a name for the first terminal, It displays that the current location based on the place (for example, near Gangnam Station exit 7) and "Yon Ho" has been requested to register the location information providing service.

Alternatively, as illustrated in FIG. 14C, when the second terminal receives the registration request for the location information providing service from the first terminal, if the second terminal stores "Jeong Yunho" as a name for the first terminal, It displays that the current location based on the distance (for example, within a radius of 1km from the second terminal) and the registration request of the location information providing service from "Jung Yoon Ho".

14A to 14C, the second terminal displays a window for selecting whether to approve the registration request of the location information providing service in one area of the screen. The second terminal informs the first terminal or server that the registration of the location information providing service has been approved when "approve" is selected through the displayed window, and informs that the registration has been rejected when "deny" is selected.

15A to 15D are state diagrams illustrating a registration process of a location information providing service.

As shown in FIG. 15A, when the second terminal receives a registration request of the location information providing service from the first terminal, the second terminal may display identification information of the first terminal, for example, a display of a telephone number "019-123-4567". Together with "019-123-4567" is displayed that the request to register the location information providing service. In this case, the second terminal displays a window for selecting whether to approve the registration request of the location information providing service in one area of the screen.

Hereinafter, the screen state when "approval" is selected through the displayed window will be described.

As shown in FIG. 15B, the second terminal has approached the location-based information based on the distance of “019-123-4567” (corresponding to the relative position information described above) within a radius of 1 km from the second terminal. Can be displayed.

Alternatively, as illustrated in FIG. 15C, the second terminal is located near the exit 7 of Gangnam Station as location information (corresponding to the administrative address information described above) based on the location of “019-123-4567”. Can be displayed.

Alternatively, as shown in FIG. 15D, the second terminal is location information based on a distance of “019-123-4567” (corresponding to a mixture of relative location information and administrative address information described above), and Gangnam Station 7 It may be displayed that the vehicle is approached within a radius of 1 km from exit 1.

The second terminals mentioned in the above-mentioned 14a to 14c and 15a to 15d may be respective terminals for displaying the screens shown in the respective drawings, and the screens shown in all the drawings may be displayed according to the situation. It may be one terminal that exists.

Next, a method of providing location information when accessing the location information providing service will be described with reference to FIGS. 16 to 27C. Hereinafter, for convenience of description, the description will be limited to the first terminal and the second terminal of the plurality of mobile terminals connected to the location information providing service.

16 is a flowchart illustrating a process of providing location information in a first terminal.

As illustrated in FIG. 16, the first terminal accesses a location information providing service through the wireless communication unit 110 (S1610). For example, when the location information providing service is a service implemented on the Internet, the first terminal may access the location information providing service through the wireless Internet module 113.

The access step S1610 may be performed as a function key provided for accessing the location information providing service is selected by the user. Or, when there is a preset connection point or connection location by the user, the first terminal, if it is recognized by the controller 180 to satisfy the preset connection point or located in the connection place, the connection step (S1610) You can also do

When the access step (S1610) is completed, the first terminal, via the display module 151, can simply display the identification information or location-based information of the terminals currently connected to the location information providing service, in particular the access The display may be displayed according to at least one group to which the terminals belong.

The first terminal stores the identification information of the first terminal in the memory 160 or the server (S1620).

Here, the identification information may be stored in advance at the time of registering for registration of the location information providing service or at any use time of the location information providing service. Therefore, the storing step S1620 may be omitted in some cases.

The first terminal transmits identification information or location-based information of the first terminal to the server or the second terminal through the wireless communication unit 110 (S1630). In this case, the server may transmit the identification information or the location-based information received from the first terminal to the second terminal.

For example, the location-based information transmitted in the transmission step S1630 may be in a hierarchically generated form corresponding to the resolution set for the second terminal.

The first terminal may select at least one mobile terminal (hereinafter, referred to as a location information receiving terminal) to receive the location-based information transmitted in the transmission step S1630. Of course, the location information receiving terminal may be any terminal registered to perform the location information providing service with the first terminal without undergoing a separate selection process.

18A to 18D, the selection process will be described in detail.

As shown in FIG. 18A, the first terminal displays a list consisting of selection conditions of the mobile terminal to receive location based information. Here, the selection condition list may include selection conditions such as distance, place name, group, and the like.

18B illustrates a case where a distance is selected in the selection condition list.

As illustrated in (a) of FIG. 18B, the first terminal may select mobile terminals located within a predetermined radius from the first terminal as the location information receiving terminal. Alternatively, as shown in (b) of FIG. 18B, the first terminal may select mobile terminals located within a predetermined radius from a specific place as the location information receiving terminal.

18C illustrates a case where a place is selected from the selection condition list.

As shown in (a) of FIG. 18C, the first terminal inputs an administrative address (for example, Yeoksam-dong, Gangnam-gu, Seoul, Korea) corresponding to a specific place in the place input window. All mobile terminals located in the administrative address can be selected. Alternatively, as shown in (b) of FIG. 18C, the first terminal selects a specific administrative address (eg, Yeoksam-dong, Gangnam-gu, Seoul) using the address list, and thus selects the selected administrative address as the location information receiving terminal. All mobile terminals located at can be selected. Here, the address list is based on the administrative district, and includes a plurality of groups in which "do / gu / gwangsi" is the first group, "city / gun / gu" is the second group, "dong" is the third group, and the like. It may be displayed as star.

18D illustrates a case where a group is selected from the selection condition list.

As illustrated in (a) of FIG. 18D, when a specific group is selected from the plurality of groups, the first terminal may select mobile terminals belonging to the selected specific group as the location information receiving terminal. In this case, the specific group may be selected by selecting an index for a specific group among the indices for each of the plurality of groups. Here, the group may be set for each of a plurality of mobile terminals registered in the location information providing service, or may be set in association with a phone book group of the first terminal. Alternatively, as shown in (b) of FIG. 18D, the first terminal may be a mobile terminal in a connected state (“on”), a mobile terminal in a non-connected state (“off”), or connected / disabled as a location information receiving terminal. One of the mobile terminals in the connected (“on / off”) state may be selected. In this case, the first terminal may display an index indicating a connected state (“on”), a non-connected state (“off”), and a connected / disconnected (“on / off”) state, respectively.

In addition, although not shown in the drawing, the first terminal may select a desired terminal from among all terminals registered to mutually perform the location information providing service as the location information receiving terminal.

In addition, although not shown in the drawings, the first terminal is located in the "province / city / metropolitan city" like me, "city / county / district" like me, "dong" like me, and the like, centering on the administrative area where it is located. It is also possible to select a mobile terminal. At this time, the "state / city / Metropolitan City", such as "city / county / district", such as me, "dong", such as me, may be displayed on the screen to form a list in order to facilitate the selection by the user have.

The first terminal may differently set location-based information to be transmitted in the transmission step S1630 for each mobile terminal or a group to which at least one mobile terminal belongs.

19, the setting process will be described in detail.

As illustrated in FIG. 19, the first terminal may set location based information to be provided for each mobile terminal or each group, and displays a list for selecting location based information. Here, the list may include coordinate information, POI information, administrative address information, setting name information, relative location information, and the like.

For example, the first terminal may be configured to provide detailed location information about itself as the intimacy is higher and to provide only rough location information about itself as the intimacy is lower according to intimacy with the first terminal. In this regard, it has been described above that resolution can be set according to intimacy.

In addition, the first terminal may set location-based information directly selected by the user as location-based information to be provided.

First, when "coordinate information" is selected from the list, the first terminal may set to provide coordinate information including longitude, latitude, altitude, time, speed, etc. of its own location point. Therefore, the second terminal can generate all the location based information on the first terminal using the coordinate information.

For example, if "Area code icon" is selected, it displays information related to that city; if "Weather icon" is selected, it displays weather information for that city; if "Area icon" is selected, local news for that city Can be displayed.

33A to 33D are screen state diagrams of a process of displaying location information according to a map mode. Here, the map mode refers to a mode in which location-based information of the location information providing terminal is provided using a map image. In addition, it is assumed that "friend" is selected from the plurality of groups for convenience of description.

In addition, the mobile terminal may include a specific region (for example, a country unit, a province unit, a city unit, a district unit, a east unit, etc.), an area where the location information providing terminal is most located, a certain distance / region based on me, and a specific region. The map mode may be performed by setting at least one of a predetermined distance / area based on the place / location information providing terminal.

As shown in Fig. 33A, the mobile terminal displays the location of each of the location information providing terminals belonging to the group " friend " on the map image. In this case, each location may be displayed by using an icon corresponding to each location information providing terminal. In addition, a name set in the location information providing terminal may be displayed together with the icon.

In addition, the mobile terminal may activate at least one of a group name, a map image, and an individual icon. For example, you can move to a different group while the group name is active, zoom in and / or reduce the scale while the map image is active, move the center on the map image, and correspond to the individual icon while the individual icon is active. The call or message may be transmitted to the location information providing terminal. Here, the activation may be performed by using a direction key, a soft key, or by a touch in the case of a touch screen.

In addition, as illustrated in FIG. 33B, the mobile terminal divides the screen into two regions, and thus, the mobile terminal of the location information providing terminals belonging to the first group (eg, "friend") using the map image in the first region. The location-based information may be provided, and location-based information of the location information providing terminals belonging to the second group (eg, “work”) using the map image in the second area may be provided.

In addition, as illustrated in FIG. 33C, the mobile terminal may divide a screen into four areas and provide location-based information of location information providing terminals belonging to each group in each divided area by using a map image. Of course, the number of divisions is not limited.

As illustrated in FIGS. 33B and 33C, the mobile terminal may divide a screen into a plurality of areas and provide a map image in which the location of the location information providing terminal belonging to a specific group is displayed in each divided area.

Although not shown in the drawing, in providing a map image for each group, when a tag corresponding to a specific group is selected from a group list provided in a tag format, the mobile terminal is located in a group corresponding to the selected tag. A map image displaying the locations of the information providing terminals may be displayed on the screen.

Although not shown in the drawings, the mobile terminal may display the location information of the location information providing terminal selected in accordance with different setting conditions (for example, region, distance, etc.) in the same group in a plurality of regions. Can be. For example, it may be used when a plurality of conditions, such as "Suwon", "5km from me", "area in which the terminals belonging to the group are located" are set in the group "friend".

In addition, as illustrated in FIG. 33D, the mobile terminal may provide location-based information using a map image to correspond to a resolution set for the location information providing terminal. For convenience of explanation, it is assumed that the higher the resolution grade, the larger the scale. Therefore, the higher the resolution grade, the more the location of the location information providing terminal can be displayed on the map image.

For example, as shown in (a) of FIG. 33D, when the resolution class is "fifth class", the mobile terminal is configured to provide a location information providing terminal on a scale map image of one hundred thousandths (1/100000). You can mark the location.

Alternatively, when the resolution class is "fourth grade" as shown in (b) of FIG. 33D, the mobile terminal determines the position of the location information providing terminal on a scale map image of 1 / 500,000 (1/50000). I can display it.

As shown in (c) of FIG. 33D, when the resolution class is “third class”, the mobile terminal may display the location of the location information providing terminal on a scale map image of 10,000 (1/10000). Can be.

34A and 34C are screen state diagrams of the position information display process according to the blending mode. Here, the mixed mode refers to a mode in which the above-described basic mode, information providing mode, map mode, etc. are mixed to provide location based information.

As shown in FIG. 34A, the mobile terminal may provide location-based information for a group "friend" in a mixture of a map mode and a basic mode.

Alternatively, as shown in FIG. 34B, the mobile terminal may provide location-based information in a form of a mixture of a map mode and a basic mode for each of the group “friends” and “accounts”.

Third Example -

Hereinafter, a method of using an additional service using a map in which another terminal location is displayed when accessing a location information providing service according to an embodiment of the present invention will be described with reference to the drawings.

The mobile terminal 100 according to an embodiment of the present invention may display information on a counterpart terminal (hereinafter, referred to as a "terminal terminal") mutually registered through a location information providing service. The mobile terminal 100 and the counterpart terminal may provide each other with information including location information through a location information providing service.

36 is a flowchart illustrating a method of performing a function of a mobile terminal according to an embodiment of the present invention.

The mobile terminal 100 may receive location information of the counterpart terminal through the wireless communication unit 110 in operation S3610. The reception of the location information of the counterpart terminal may be performed in real time or may be performed at predetermined time intervals. The predetermined time may be determined based on resolution. For example, when the resolution level is 1, the location information of the counterpart terminal may be received at 1 minute intervals, and when the resolution level is 5, the location information of the counterpart terminal may be received at 10 minute intervals.

The controller 180 may display information on the counterpart terminal, including location information of the counterpart terminal, on the display unit 151. The method of displaying information of the counterpart terminal may be in various forms. For example, the location of the counterpart terminal may be displayed on the map in the form of an icon (S3620). That is, the controller 180 can display a map on which the location of the counterpart terminal is displayed on the display unit 151. The center point of the map displayed on the basis of the controller 180 may be changed. As the center point changes, the counterpart terminal displayed may vary.

37 is a diagram illustrating a location of a counterpart terminal displayed on a map according to a specific criterion in a mobile terminal according to an embodiment of the present invention.

The specific criteria may be determined in various forms. For example, as shown in FIG. 37A, the current location of the mobile terminal 100 may be a specific criterion. That is, the other terminal located within a predetermined distance with respect to the current location of the mobile terminal 100 may be displayed on the map. In this case, the user may know which counterpart is located around him.

In addition, as illustrated in FIG. 37B, the position of one terminal terminal among terminals registered to the location information providing service may be a specific criterion. For example, a counterpart terminal located within a predetermined distance with respect to the current location of the terminal using the ID "Jermaine" may be displayed on the map. In this case, the user may know which counterpart is located around the counterpart using the ID "Jermaine".

In addition, as shown in FIG. 37C, a specific region may be a specific criterion. For example, a counterpart terminal located within a predetermined distance from the "Gangnam Station" may be displayed on a map. In this case, the user may know which counterpart is located near the "Gangnam Station".

Meanwhile, according to an embodiment of the present invention, the controller 180 can group a plurality of counterpart terminals according to a specific criterion. The location of the terminal may be displayed by a separate map for each group formed through the grouping. That is, the location of the counterpart terminal belonging to the first group may be indicated on the first map, and the location of the counterpart terminal belonging to the second group may be indicated on the second map. Such an example is shown in FIG. 38.

As shown, four groups are formed through the grouping. The formed group is displayed in the form of a tab at the top of the screen. When a specific tab is selected from the displayed tabs, the controller 180 can display a map in which the location of the counterpart terminal belonging to the group related to the selected tab is displayed.

FIG. 38A illustrates a map in which a location of a counterpart terminal belonging to a group related to a tab of "friend" is displayed when a tab of "friend" is selected. That is, only the terminals belonging to the "friends" group among the counterpart terminals located within a predetermined distance centered on a specific area are selected, and only the selected terminals are displayed on the corresponding location on the map. The "friend" group refers to one of the groups managed through the location information providing service.

38B illustrates a map in which a location of a counterpart terminal belonging to a group associated with a tab named "Gangnam Station" is displayed when a tab named "Gangnam Station" is selected. That is, the other terminal located within a predetermined distance centering on the "Gangnam Station" is displayed on the corresponding position on the map.

FIG. 38C illustrates a map in which a location of a counterpart terminal belonging to a group associated with a tab named "withdrawal" is displayed when the tab "withdrawal" is selected. That is, the counterpart terminal located within a predetermined distance centering on the location of the terminal corresponding to the ID of “Brother” is displayed on the corresponding location on the map.

38A to 38C, the controller 180 can display the selected tab to be distinguished from other tabs.

Meanwhile, according to an embodiment of the present invention, when a specific condition is satisfied, the controller 180 can automatically generate a group of the counterpart terminals and display it on the map. For example, when five or more counterpart terminals are located within a radius of 5 km from the Gangnam station, the controller 180 automatically generates a map on which the five terminals are displayed, and displays the generated map on the display unit 151. Can be displayed.

Further, according to an embodiment of the present invention, the scale of the map shown according to the resolution may be determined. The resolution may be set differently according to the region. For example, resolution may be differentially set based on the activity of the user. For example, the resolution level may be set to 1 for a region having a large amount of active time, and the resolution level may be set to 3 for a region having a small amount of active time.

In addition, the resolution may be determined based on the degree of information disclosure set for each terminal. The degree of information disclosure may be determined based on intimacy with the counterpart terminal. Intimacy may be set for each counterpart terminal, or when the counterpart terminals are managed in groups, intimacy may be set for each group. That is, resolution may be determined according to intimacy. For example, when the intimacy is 10, the resolution level may be set to 1, and when the intimacy is 5, the resolution level may be set to 3.

39 is a diagram illustrating a scale displayed differently according to resolution in a mobile terminal according to one embodiment of the present invention.

As shown, FIG. 39A shows a map having a relatively high resolution level and a large scale, and FIG. 39B shows a map having a relatively low resolution level and a small scale. The scale is shown in the upper right of the displayed screen. 39A shows a scale of 1: 20,000 and FIG. 39B shows a scale of 1: 40,000. The scale may be changed by key manipulation of the user input unit 130. For example, you can use the scroll keys to change the scale of the map. However, unless the resolution is changed, it may not be changed by the key operation of the user input unit 130.

Meanwhile, the mobile terminal 100 according to an embodiment of the present invention may select a specific terminal among the counterpart terminals to perform a specific function related to the selected terminal (S3630 and S3640). That is, when a specific terminal is selected among the counterpart terminals, the controller 180 may perform a specific function related to the selected terminal.

Meanwhile, the mobile terminal 100 may include a touch screen. In this case, the selection of a specific terminal may be made through a touch input. As described above, an example of a method of selecting a specific terminal through a touch input is illustrated in FIG. 52.

40A illustrates a screen on which a counterpart terminal is displayed in an icon form on a map. Identification information is displayed on the displayed icon to identify which counterpart. The icon on the map tells you where your opponent is. The mobile terminal 100 may select and display only the counterpart terminal that is connected to the location information providing service.

In addition, the user of the mobile terminal 100 may manage the other terminal by grouping. In this case, only the icon corresponding to the counterpart terminal belonging to a specific group may be displayed on the map. Only the counterpart terminal belonging to the "Friend" group is displayed on the screen. In this case, the user may check the counterpart terminal belonging to another group by touching the direction ��¤ 4001 of the window in which the group name is displayed.

In addition, the controller 180 may move the center of the displayed map when the direction key 4003 displayed on the map is touched by the user. The counterpart terminal located in another area may be identified by moving the map.

In addition, the user may touch the "+,-" displayed at the bottom of the screen to enlarge or reduce the displayed map. Of course, you may not be able to zoom in or out on the map displayed by keystrokes unless there is a change in the resolution of the map.

Meanwhile, a specific terminal may be selected among the counterpart terminals displayed on the map by a user's touch input.

40B illustrates an example in which a specific terminal is selected by a touch input. After the user touches the screen on which the map is displayed, the user draws a closed curve 4005 to select a specific terminal within the closed curve. That is, when the closed curve is drawn on the map by a user's touch input, a specific terminal existing in the closed curve is selected. In this case, one specific terminal may be selected or a plurality of specific terminals may be selected.

The controller 180 may perform a specific function related to the selected specific terminal. For example, the specific terminal may perform a specific function related to the selected specific terminal through the entry of "option" in the selected state. The particular function may vary.

Examples of the specific function include a voice call or a video call or a message or data transmission using a short message service (SMS), a multimedia message service (MMS), an e-mail, an instant message (IM), or a Bluetooth. There is this. In addition, there is an information display on the region where the selected specific terminal is located, and a road guide to the selected terminal.

The controller 180 may recognize a specific character or a specific symbol written on the screen and perform a specific function corresponding to the written specific character or the specific symbol. 41 shows such an example.

As shown in the drawing, a specific character may be input through writing on a screen on which the closed curve 4005 is drawn to perform a specific function for selecting a specific terminal. For example, when "S" is input by hand, the mobile terminal 100 may transmit a message to the selected specific terminal by using a short message service (SMS). In addition, when "C" is input by hand, the mobile terminal 100 may transmit a call signal to the selected specific terminal (not shown). In this case, the controller 180 may recognize handwriting of the user as a signal for performing a specific function.

Meanwhile, according to one embodiment of the present invention, the mobile terminal 100 may set a specific character to match a specific function. For example, "E" may be set to match E-mail usage, and "I" may be set to match Instant Message (IM) usage.

When a specific character and a specific function are matched in the above-described manner, the user may input (not shown) handwriting "E" in the closed curve 4005 to perform data transmission via email. That is, when "E" is input by the user's handwriting in the closed curve 4005, the controller 180 may perform data transmission through an e-mail.

The specific function related to the selected terminal may be performed in the following form. For example, the mobile terminal 100 may transmit a call signal to the selected specific terminal to perform a voice call or a video call.

In addition, the mobile terminal 100 may transmit a message or data using a selected specific terminal as a receiving terminal using a short message service (SMS), a multimedia message service (MMS), an e-mail, or the like.

In addition, the user of the mobile terminal 100 may use the IM (Instant Message) to chat with the selected terminal user. In particular, when a plurality of specific terminals are selected, multi-party chats can also be performed.

In addition, when the selected specific terminal is located in close proximity to the mobile terminal 100, the mobile terminal 100 may perform near field communication using Bluetooth.

In addition, the mobile terminal 100 may inform the information about the region where the selected specific terminal is located. For example, if the selected terminal is located in another country, the sub-menu may inform the country of the country's weather, exchange rate, comprehensive stock price of the corresponding country, local traffic information, local news, and the like.

Meanwhile, the mobile terminal 100 according to an embodiment of the present invention may perform the specific function in consideration of characteristics of the selected specific terminal.

For example, the mobile terminal 100 transmits a message to a selected terminal by using a short message service (SMS), a multimedia message service (MMS), an e-mail, or an instant message (IM). Can be translated into the language of the country where the selected terminal is located and transmitted. Such an example is shown in FIG. 42.

As shown, the message content written in Korean may be translated into the language of the country where the selected terminal is located. The mobile terminal 100 may perform the translation work using an automatic translation program. If the country where the selected terminal is located is an American, the mobile terminal 100 may automatically translate the message content written in Korean and transmit it to the selected terminal.

Meanwhile, since the functions supported by the mobile terminal 100 and the selected terminal may be different from each other, the mobile terminal 100 may perform a specific function in consideration of compatibility with the selected terminal. For example, when transmitting a message, if the mobile terminal 200 transmits a special character, font, etc. that can be supported, the transmission is successful, but the receiving side (selected terminal) does not support the same function. If not, the message is shown in a broken form, so the other party (the selected terminal user) cannot check the message contents normally. If it is assumed that the selected terminal has a viewer that can open and view an image file, converting the message into an image and transmitting the message to the receiving terminal allows the selected terminal to grasp the contents of the message normally.

According to an embodiment of the present invention, when the extracted message is to be converted into an image, it may be determined whether the extracted message has a specific symbol or not to convert into an image. The specific symbols may include foreign characters (for example, hiragana or katakana), symbols, graphic images, fonts, special characters, and symbols drawn by handwriting of the user when the mobile terminal includes a touch pad. Can be. The symbol drawn by the user's handwriting may include letters, numbers, symbols, pictures, and the like.

The check of whether a specific symbol is included in the extracted message may be directly checked by the user or may be checked by the mobile terminal 100 to inform the user.

When the specific symbol is checked in the mobile terminal 100, the specific symbol may be used as the default in the mobile terminal 100, or may be set by the user. For example, the special symbol may default to a specific symbol in the mobile terminal 100. In this case, if the special symbol is included in the extracted message, the controller 180 may display a pop-up window indicating that the specific symbol is included. In addition, the user can set a foreign character (eg, hiragana or katakana) as a specific character. In this case, if the set foreign character is included in the extracted message, the controller 180 may display a pop-up window indicating that a specific symbol is included.

The method of notifying that a specific symbol is included through the pop-up window is just an embodiment, which does not limit the present invention. For example, the voice output or vibration output may indicate that a particular symbol is included in the extracted message.

If the extracted message includes a specific symbol, the extracted message may be converted into an image. In this case, the extracted message may include only the content of the message. For example, the display module may not include an indicator displayed on the display module and may extract only the content portion of the message and convert the image into an image. In this case, the message portion that is converted into an image includes not only the current display on the screen but also the message portion that can be viewed by using a scroll key or a navigation key.

And transmit the image. In this case, the controller 180 may transmit the original message and the image together. The image transmission may be transmitted using MMS or may be transmitted using E-mail.

43 is a diagram illustrating a method for converting a message into an image and transmitting the same in a mobile terminal according to one embodiment of the present invention.

Fig. 43A shows an example in which a message is created including specific foreign characters and symbols (umbrella symbols). In this case, the foreign characters and symbols may be recognized as specific symbols. The controller 180 may analyze whether a specific symbol is included in the message by receiving the “confirmation” key shown on the screen. That is, when "OK" is selected in the illustrated screen, a screen as shown in FIG. 43B is displayed.

As shown, a pop-up window 4301 is displayed indicating that the message contains a particular symbol. When "OK" is selected on the screen shown, the created message is converted into a file and transmitted (FIG. 43C). In this case, the original message may be transmitted together with the image. Image file transfer can be performed using MMS.

Meanwhile, when the selected terminal does not recognize a message including a symbol (including letters, numbers, pictures, etc.) written through the user's handwriting, the mobile terminal 100 may convert the message into an image and transmit the message. .

FIG. 44 is a diagram illustrating a method for converting a message created by handwriting of a user into an image and transmitting the same in an image in a mobile terminal according to an embodiment of the present invention.

Fig. 44A shows an example of a message written by handwriting. In this case, a symbol written by handwriting may be recognized as a specific symbol. The controller 180 may analyze whether a specific symbol is included in the message by receiving the “confirmation” key shown on the screen. That is, if "OK" is selected in the illustrated screen, a screen as shown in FIG. 44B is displayed.

As shown, a pop-up window 4401 is displayed indicating that the message contains a particular symbol. If " OK " is selected in the illustrated screen, the created message is converted into a file and transmitted (Fig. 44C). In this case, the original message may be transmitted together with the image. Image file transfer can be performed using MMS.

Meanwhile, according to an embodiment of the present invention, the specific function may be performed in consideration of the location of the selected counterpart terminal.

For example, the mobile terminal 100 may display a distance from the selected terminal. Such an example is shown in FIG. 45. 45A illustrates a case where a terminal having an ID of "Jermaine" is selected. In this case, the distance to the selected terminal may be checked through option entry or the above-described specific character input. As shown in FIG. 45B, the distance to the selected terminal may be displayed in the form of a pop-up window to inform the user of the distance to the selected terminal. In addition, the user may be notified of the distance to the selected counterpart through the voice output.

4th Example -

Next, the mobile terminal 100 according to an embodiment of the present invention will be described a method of performing a road guide using a location of a specific counterpart terminal as a destination. The specific terminal refers to one terminal of mutually registered terminals through a location information providing service.

46 is a flowchart illustrating a method of performing a road guide using a location of a specific terminal as a destination in a mobile terminal according to an embodiment of the present invention.

The mobile terminal 100 may receive the location information of the specific terminal registered in the location information providing service to the wireless communication unit 110 (S4610). The location information of the specific terminal may be received at predetermined time intervals. The predetermined time may be determined based on the resolution. For example, when the resolution level is 1, the location information of the specific terminal may be received every minute, and when the resolution level is 3, the location information of the specific terminal may be received every 10 minutes.

The resolution may be determined based on the degree of information disclosure set for each terminal. The degree of information disclosure may be determined based on intimacy with the counterpart terminal. Intimacy may be set for each counterpart terminal, or when the counterpart terminals are managed in groups, intimacy may be set for each group. That is, resolution may be determined according to intimacy. For example, when the intimacy is 10, the resolution level may be set to 1, and when the intimacy is 5, the resolution level may be set to 3.

The controller 180 may perform the road guidance using the location of the specific terminal as a destination (S4620). The controller 180 may perform the received location information of the specific terminal. In addition, the controller 180 may perform the road guidance at the predetermined time interval, which is a period for receiving location information of a specific terminal.

FIG. 47 is a diagram illustrating a screen for performing a road guide to a specific terminal as a destination in a mobile terminal according to an embodiment of the present invention. FIG.

FIG. 47A illustrates a screen for performing directions using a terminal named "Jermaine" which is one of terminals registered in the location information providing service as a destination. You can enlarge or reduce the displayed map by using the "+" or "-" menu displayed at the bottom of the screen. That is, the controller 180 may enlarge or reduce the displayed map when a signal related to "+" or "-" is input.

47B to 47D show a more detailed road guidance screen through the enlargement of the map. That is, the controller 180 can enlarge the displayed map through the "+" key input. Detailed road guidance information for each specific section may be checked through the screens illustrated in FIGS. 47B to 47D.

Meanwhile, according to an embodiment of the present invention, when the location of a specific terminal set as a destination is changed, the mobile terminal 100 may inform the moving path of the specific terminal (S4630 and S4640). The destination may be changed to a location of the moved specific terminal to perform the road guidance (S4650).

48 is a diagram illustrating a method of performing a road guide to a specific terminal moving in a mobile terminal according to an embodiment of the present invention.

As illustrated, when the location of a specific terminal set as a destination (terminal named Jermaine ID) is changed, the controller 180 may display a pop-up window informing of a movement path and a destination change of the specific terminal (FIG. 70A). .

When "OK" is selected on the screen shown in FIG. 48A, the controller 180 changes the location of the changed specific terminal to the destination and performs the road guidance (FIG. 48B). The controller 180 displays a road guidance screen to the changed destination.

Meanwhile, according to an embodiment of the present invention, the mobile terminal 180 may perform a road guide to change the destination only when the movement of a specific terminal exceeds a threshold range. The reason for determining the threshold range as described above is that if the location of a specific terminal is changed slightly, the change of destination is not significant. When the destination is changed every time even when the location of the specific terminal is changed slightly, the amount of calculation of the controller 180 increases. In addition, for the same reason, the controller 180 can notify the movement path of the specific terminal only when the movement of the specific terminal exceeds the threshold range. The threshold range may be determined based on resolution.

The controller 180 may calculate the moving speed of the mobile terminal 100 using the location information of the mobile terminal 100 received through the location information module 115. In addition, the controller 180 may calculate a moving speed of the specific terminal using the received location information of the specific terminal.

The controller 180 may inform the expected meeting place based on the calculated moving speed of the mobile terminal 100 and moving speed of a specific terminal. In addition, route guidance information to the expected meeting place may be transmitted to the specific terminal. Such an example is shown in FIG.

As illustrated, the controller 180 may display a pop-up window including an expected meeting place determined based on the moving speed of the mobile terminal 100 and the moving speed of a specific terminal (FIG. 49A). The pop-up window displays an expected meeting place and an expected meeting time. In addition, according to FIG. 49B, the controller 180 may display a road guidance screen to the expected meeting place.

The controller 180 may transmit the road guide information to the specific terminal to the expected encounter point. The road guide information may include a travel route to a predicted meeting place and a budget time. In addition, the road guidance information may include road guidance information from the current location of the specific terminal to the expected meeting place.

On the other hand, according to one embodiment of the present invention, when the movement path or the movement speed of a specific terminal is changed to the threshold range or more, or when the movement path or the movement speed of the mobile terminal 100 is changed to the threshold range or more, the expected meeting place Can be changed. The threshold range may be determined based on resolution. In this case, the controller 180 may inform the user of the changed predicted meeting place and the changed guidance meeting place to the user or transmit the information to the specific terminal. Such an example is shown in FIG. 50.

Referring to FIG. 50A, the controller 180 may display a pop-up window in which the time required for the changed expected meeting place and the changed expected meeting place is displayed. In addition, according to FIG. 50B, the controller 180 may display a road guidance screen to the changed expected meeting place.

On the other hand, the mobile terminal 100 according to an embodiment of the present invention may display information on the counterpart terminal (hereinafter referred to as the "terminal terminal") mutually registered through the location information providing service. The mobile terminal 100 and the counterpart terminal may provide each other with information including location information through a location information providing service.

The mobile terminal 100 may support a meeting function service with a selected terminal user. For example, the mobile terminal 100 may perform a road guidance function to the selected terminal. If the selected terminal is moving, it can be notified to the user. In particular, when the location of the selected terminal changes significantly by moving, the user can be notified.

FIG. 51 is a diagram illustrating a method of performing a meeting service with a selected counterpart (selected terminal user) in a mobile terminal according to one embodiment of the present invention.

51A is a screen illustrating that a selected terminal is moving when the selected terminal is moving. As illustrated, when the selected terminal is moving, a light 5101 may be displayed on an acon indicating the selected terminal. The user may recognize that the selected terminal is moving due to the display of the light 5101.

In addition, the mobile terminal 100 may also support a meeting time service with the selected counterpart (the user of the selected counterpart terminal). An example thereof is shown in FIG. 51B. As shown, when the counterpart terminal is moving, the mobile terminal 100 can inform the user of the movement direction and the scheduled time of meeting in the form of a popup. Estimated meeting time can be found at the current speed of travel. In addition, the movement speed may be directly obtained by the user.

In addition, when the selected counterpart terminal deviates from the route so that it cannot know the expected time of meeting, the screen shown in FIG. 51C may be displayed.

In addition, the mobile terminal 100 may also inform information about a specific location displayed on the map. 52 shows such an example.

FIG. 52A illustrates a screen in which the mobile terminal 100 displays a distance to a selected specific location and an expected arrival time when a location of a COEX displayed on a map is selected through a touch. As shown, when the user selects the location of the COEX displayed on the map by touching, the mobile terminal 100 may display the distance to the COEX and the expected arrival time in the form of a pop-up window.

In addition, the mobile terminal 100 may recommend a meeting place with the selected counterpart terminal user. 52B shows such an example. As shown in the drawing, the mobile terminal 100 may display the expected meeting time with the other party (the selected terminal user) in the form of a pop-up window when meeting the recommended specific location and the recommended location. In this case, the user may transmit a message displayed in the pop-up window to the counterpart terminal through "message transmission".

In addition, as illustrated in FIG. 52C, after the user selects a specific location on the map, the user may check the distance between the selected specific location and the counterpart terminal. That is, the mobile terminal 100 may display a distance between the specific location and the counterpart terminal and an expected time at which the counterpart terminal arrives at the specific location in the form of a pop-up window.

In addition, the mobile terminal 100 may check a list of recent calls with the selected counterpart terminal user (referred to as the selected counterpart). 53 is a view illustrating a call list with a selected counterpart. As shown, the call list is displayed in order of the latest call. The displayed list shows the talk time, the time of call, whether the call was made through a call or a call signal reception.

-5th Example -

Hereinafter, a method of generating a mobile history of the mobile terminal 100 in the mobile terminal 100 according to an embodiment of the present invention will be described. The movement history may exist in various forms. For example, a time and place may be present in a table form, or may be present in a movement trajectory on a map.

54 is a flowchart illustrating a method of generating a mobile history in a mobile terminal according to an embodiment of the present invention.

First, the mobile terminal 100 may receive location information through the wireless communication unit 110 (S5410). The location information may be received in real time or at predetermined time intervals.

The controller 180 may store the current location and the current time in the memory 160 at predetermined time intervals based on the received location information (S5420). The controller 180 may generate a movement trajectory in which time information is displayed using the information including the current position and the current time at the predetermined time interval, and display the movement trajectory on the display unit 151 (S5430).

55 is a diagram illustrating an example of generating a movement trajectory in a mobile terminal according to one embodiment of the present invention.

As shown, the movement trajectory of the mobile terminal is displayed on the map. On the screen displaying the movement trajectory, time information stayed at a specific place is displayed. The movement trajectory is distinguished according to the movement speed. That is, the controller 180 can display the movement trajectory differently according to the movement speed. As shown, when the moving speed is fast based on a specific speed, it may be displayed as a solid line, and when the moving speed is slow, it may be displayed as a dotted line. On the other hand, the controller 180 may give a grade to the moving speed, and display the grade differently through the display color of the moving trajectory for each corresponding grade (not shown).

In addition, the controller 180 may further include a specific record in addition to the time information to generate the movement trajectory. The specific record may be a record associated with a specific time. For example, when a specific music file is played for a specific time in the mobile terminal 100, a record 5501 of playing a music file may be displayed on the movement trajectory. In addition, a specific text or a specific image may be displayed at a specific position where time information is displayed on the movement trajectory. Through the specific text or the specific image, the user may record and remember the time and the work done at the corresponding place. In the illustrated screen, a specific image 5503 is displayed.

In addition, when the specific record displayed is selected through a key input, the controller 180 may reproduce a data file related to the specific record. 56 shows such an example.

FIG. 56 illustrates that when the specific record 5501 is selected in FIG. 55, the controller 180 displays a list of music files that have been played during movement. If a specific music file is selected from the played music list, the controller 180 can play the selected music file. In addition, the controller 180 can display detailed information on the selected file. For example, it may display information such as how many minutes the selected music has been played, when the time was played, and where the exact place was played.

In addition, when the displayed specific record is selected through a key input, the controller 180 may link to a specific screen related to the specific record. Such an example is shown in FIG. 57.

FIG. 57 illustrates that when a specific image 5503 is selected in FIG. 55, a link to a specific screen associated with the selected image 5503 is performed. The specific image 5503 may be an image of a specific restaurant, and a linked screen (shown in FIG. 57) may be a homepage screen of the specific restaurant.

Meanwhile, according to an embodiment of the present invention, the mobile terminal 100 may generate the movement trajectory for a predetermined time and store the movement trajectory as a data file in the memory 160 (S5440). An example of storing the movement trajectory as a data file is shown in FIG. 58.

58A illustrates a movement trajectory of the mobile terminal 100 from 08:00 to 22:30. When the illustrated movement trajectory is stored through the "storage" key input, a screen as shown in FIG. 58B may be displayed. That is, when a key is input to "store", the controller 180 stores the movement trajectory during the time as a data file. When the saving is completed, the screen as shown in FIG. 58B may be displayed. The screen allows the user to check the stored data file. The controller 180 can default the name of the data file to a date corresponding to the movement trajectory. For example, in the case of the movement trajectory corresponding to October 1, 2007, the file name may be stored as "2007/10/01". The user can utilize the data file as a diary representing the movement trajectory (for convenience, referred to as a 'mobile diary').

In addition, the controller 180 may upload the stored mobile diary to a specific website (S5450). The upload not only helps to efficiently use the storage space of the mobile terminal but also helps to share the sharing of the mobile diary with others.

59 is a diagram illustrating an example of uploading a mobile diary in a mobile terminal according to one embodiment of the present invention. If the "Upload" menu is selected with any of the stored mobile diaries selected (Figure 59A), the selected mobile diary is uploaded to a particular website. 59B shows a screen in which the selected mobile diary is uploaded to a specific website.

Meanwhile, the mobile terminal 100 according to an embodiment of the present invention may further include the movement trajectory of the specific terminal registered in the location information providing service in the movement trajectory of the mobile terminal 100. Such an example is shown in FIG. 60.

As shown, the movement trajectory drawn by the solid line represents the movement trajectory of the mobile terminal 100, and the movement trajectory drawn by the dotted line represents the movement trajectory of the specific terminal. Of course, when the mobile terminal 100 and the specific terminal is moved in the same time zone, both the point trajectory and the solid line are displayed as the movement trajectories. The user may know how to interact with a specific counterpart in the movement trajectory illustrated in FIG. 60.

Hereinafter, a method of providing a history of a terminal location when accessing a location information providing service according to an embodiment of the present invention will be described with reference to the drawings.

The mobile terminal 100 according to an embodiment of the present invention displays a mobile history of a specific terminal (hereinafter, referred to as a "terminal terminal") that is mutually registered through a location information providing service or to a specific terminal. It can transmit its own mobile history.

The mobile history may be obtained using history information of the base station information and the location information module 115. In particular, the history information of the location information module 115 may include a history of the GPS location information. The movement history may be expressed in association with a map.

61 to 62 are diagrams illustrating a mobile history of a specific terminal in a mobile terminal according to an embodiment of the present invention.

As illustrated in FIG. 61, the mobile terminal 100 may show a mobile history of a selected terminal in association with a map. In the illustrated screen, a mobile history of a terminal having an ID of "Adrian" is displayed. In this case, the user may set a specific time to display the movement history based on the set time. For example, a user may select a terminal with an ID of "Adrian" to see how the selected terminal moves during a particular time zone (for example, August 15, 2007, from 9:00 AM to 6:00 PM). You can check. In this case, the map can be enlarged or reduced by inputting the "+" or "-" key signal.

In addition, as illustrated in FIG. 62, the mobile terminal 100 may display the mobile history of the plurality of terminals on one screen. In this case, the map can be enlarged or reduced by inputting the "+" or "-" key signal. The mobile terminal 100 may display the mobile history of the plurality of terminals based on a specific region. For example, the mobile terminal 100 may designate the vicinity of "Yeouido" to display the movement history of the counterpart terminal moving in the designated area.

In addition, the mobile terminal 100 may select only the counterpart terminal located within a predetermined distance from the mobile terminal 100 to display the mobile history of the counterpart terminal. For example, the mobile terminal 100 may show the mobile history of the counterpart terminal located within a range of 1 km with the mobile terminal 100.

In addition, the mobile terminal 100 may designate a specific time and a specific place to show the mobile history of the counterpart terminal via or located at the designated place at the specified time. For example, the transfer history of the counterpart terminal located through or near Yeouido may be shown from 3 pm to 9 pm on August 15, 2007.

In addition, the mobile terminal 100 may select only the counterpart terminal belonging to a specific group, and may display the mobile history of the selected terminal. For example, the mobile terminal 100 may select only the counterpart terminal belonging to the "friend" group to show the mobile history of the selected terminal.

Meanwhile, the mobile terminal 100 may search for a specific region and display the frequency of the terminal via the region. For example, the mobile terminal 100 can obtain the frequency of the terminal that has moved to the Gangnam Station area using "Gangnam Station" as a search area.

FIG. 63 shows a screen displaying a frequency of a terminal searching for a specific area in the mobile terminal 100 according to an embodiment of the present invention and moving the searched area.

63A illustrates a method of selecting a specific area by drawing a closed curve. When the mobile terminal 100 has a touch screen, the user can draw the closed curve through a touch input. In this case, the user may calculate the frequency by considering the search period. For example, the mobile terminal 100 may pass through the vicinity of Gangnam Station for one month in August 2007, or may calculate and show the frequency of the terminal that has ever been in the Gangnam Station area.

FIG. 63B is a screen showing a counterpart terminal that has been located or has been located within a searched area during a search period based on a specific criterion. In the illustrated screen, " ID (or phonebook name, location information providing service use ID) / total number of locations / total stay time " of the other party's terminal is displayed. The sorting rank is based on the total number of positions. However, the sort order may be changed according to a specific item of the mobile terminal 100. For example, the order of the counterpart terminal may be changed based on the total stay time.

6th Example -

Hereinafter, the mobile terminal 100 according to an embodiment of the present invention will be described a method of publishing the mobile information to the terminal registered in the location information providing service. The movement information may include a movement history. In this case, the mobile terminal 100 may disclose the mobile information of the actual mobile terminal 100, but the virtual mobile information may be disclosed to the terminal registered in the location information providing service for privacy protection or the like.

64 is a flowchart illustrating a method of releasing virtual mobile information to a terminal registered to a location information providing service in a mobile terminal according to an embodiment of the present invention.

First, the controller 180 displays virtual movement information stored in the memory 160 (S6410). The virtual movement information may be transmitted from a specific website, but may be generated by setting by user setting. For example, the controller 180 may generate virtual mobile information that uses the current location of the mobile terminal 100 as a starting point and a specific location as a destination. The specific position may be set in the user by manipulating the input unit 130. The controller 180 may transmit the virtual movement information to a terminal registered to the location information providing service at predetermined time intervals. The predetermined time may be determined based on the resolution. In addition, the amount or quality of the virtual mobile information transmitted according to resolution may also vary.

On the other hand, the controller 180 may perform a road guidance simulation using the current location of the mobile terminal 100 as a starting point and the specific location. The directions simulation helps the user to generate the virtual movement information. The virtual movement information may include a virtual movement speed and a virtual movement path.

On the other hand, if the virtual speed is input, the controller 180 may perform a road guidance simulation. In addition, the controller 180 may generate a virtual current location based on the virtual moving speed and transmit the generated current location to the terminal registered in the location information providing service.

65 is a diagram illustrating an example of generating virtual mobile information through road guidance simulation in a mobile terminal according to one embodiment of the present invention.

As shown in FIG. 65A, when a specific position is selected by key input of the user input unit 130, the selected specific position becomes a destination at a specific time. When the user input unit 130 includes a touch screen, the specific region may be selected through touch input. For example, when a specific point displayed on the map is touched, the controller 180 may determine the touched point as the specific area.

FIG. 65B illustrates a screen on which the time stayed at the specific point may be input when the “moving simulation” menu is selected on the screen illustrated in FIG. 65A. In this case, the user may input a time stayed at the selected specific point. That is, the controller 180 may perform the road guidance simulation based on the time input by the user input.

65C illustrates a screen on which a moving means may be input for each section. The virtual moving speed may be determined by the moving means. For example, the virtual bus speed is set to 60 km per hour, the walking is set to 5 km per hour, the virtual speed is set to 75 km per hour, and the road guidance simulation may be performed.

FIG. 65D illustrates a screen on which the movement simulation is performed based on the time stayed at the specific point set by the input and the virtual moving means. In the illustrated screen, a virtual movement trajectory displaying time information is displayed. The movement trajectory is displayed on the movement trajectory.

The controller 180 may generate a virtual movement trajectory based on the road guidance simulation performed by the method illustrated in FIG. 65, and store the generated virtual trajectory in the form of a data file in the memory 160.

66 illustrates a screen displaying a virtual movement trajectory stored in a file form in a mobile terminal according to an embodiment of the present invention. In the illustrated screen, a virtual movement trajectory generated based on a specific position set by a user is displayed.

When the specific virtual movement trajectory is selected, the controller 180 may modify or delete the selected virtual movement trajectory.

67 is a diagram illustrating an example of releasing movement information of a mobile terminal 100 according to an embodiment of the present invention. The movement information may include a movement history. In addition, the movement history may include a movement trajectory.

As shown, the mobile terminal 100 may determine whether to disclose the mobile history to the counterpart terminal (FIG. 67A). When determining to publish the mobile history, the user can select a mobile history publishing mode to be published (FIG. 67B). For example, the user may provide the other party with the actually moved movement history (1. actual movement mode in FIG. 67B), or may provide a virtually generated movement history to the other terminal (2 in FIG. 67B, virtual mode). ). In the screen illustrated in FIG. 67B, when “2. virtual mode” is selected, the controller 180 may display a virtual movement history (eg, a virtual movement trajectory) stored in the memory 160 (FIG. 67C). ). The virtual mobile history can be added, modified, or deleted.

FIG. 68 is a view illustrating a method for newly adding a virtual mobile history template in the mobile terminal 100 according to an embodiment of the present invention.

As shown, the user can enter a place that was located at that time (FIG. 68A). When the input is completed, the user can select a "complete" item. When the "Complete" item is selected, it is possible to determine whether to save the newly created virtual movement history template (FIG. 68B). In this case, the user may also input the name of the virtual mobile history template.

Meanwhile, the user of the mobile terminal 100 may store his mobile history in the form of a diary.

69 is a diagram showing a method of storing a mobile history of a mobile terminal according to one embodiment of the present invention. As shown, the user can set the mobile history storage function (FIG. 69A). When the function is set, the mobile history of the mobile terminal 100 is automatically stored from the set time. In this case, the time at which the function is performed may be the default or may be set by user input (FIG. 69B). For example, the time at which the function is released may be defaulted to be midnight of the day when the function is set, and the mobile history storage function may be set to midnight of the day set by the user for storing the daily routine in the form of a diary. It can also be set to release time. In addition, the mobile history storage function may be repeatedly performed for each specific period. Therefore, one movement history template may be stored for each specific period.

Meanwhile, according to an exemplary embodiment of the present invention, the mobile terminal 100 may also check information on whether the location information providing service is connected through the mobile history of the counterpart terminal. That is, the user of the mobile terminal 100 may check at which point and at what time the counterpart terminal accesses the location information providing service, and at which point and at what time the counterpart terminal is disconnected from the location information providing service. .

Hereinafter, a method of displaying location information for a specific person when accessing a location information providing service according to an embodiment of the present invention will be described with reference to the drawings.

Through the mobile terminal 100 according to an embodiment of the present invention, a user may check real-time information of mutually registered terminals (hereinafter, referred to as 'the other terminal') through a location information providing service. In this case, the mobile terminal 100 may select a specific terminal among the counterpart terminals and check the real time information of the selected terminal. In addition, the mobile terminal 100 may select its own counterpart terminal and transmit its real time information to the selected terminal. In the present specification, the real time information refers to current state information of the terminal. For example, the real-time information of the counterpart terminal may include a current distance between the mobile terminal 100 and the counterpart terminal, a moving speed of the counterpart terminal, weather information of a place where the counterpart terminal is currently located, and the like.

70 to 50 are diagrams illustrating a state in which real-time information of a counterpart terminal is displayed in a mobile terminal according to an embodiment of the present invention.

The real time information may be displayed in the form of an icon 7001. By displaying the icon 7001 in the indicator area, the user can check the real time information of the selected counterpart terminal at any time. Through the displayed icon 7001, the user can check the distance and the moving speed with the selected counterpart. The distance from the selected counterpart terminal is within 5 km (indicated by the number), and the moving speed is less than 5 km / h per hour, indicating that the moving distance is small or almost stopped.

70B illustrates that the real time information of the counterpart terminal is displayed on a screen on which a specific application is executed. That is, the mobile terminal 100 may display real time information of the selected counterpart not only on the standby screen but also on a screen on which a specific application is executed. When the real time information of the selected terminal changes, the mobile terminal 100 may allow the user to recognize that the real time information is changing. The mobile terminal 100 displays the real time information by an icon 7003 in which a light is displayed so that the user recognizes that the real time information of the selected terminal is changing. Through the displayed icon 7003, the user can check the distance and the moving speed with the selected counterpart. The mobile terminal 100 indicates that the distance to the selected counterpart terminal is within 5 km (indicated by a number), and is approaching a user about 5 km / h to 20 km / h per hour.

Meanwhile, the mobile terminal 100 may know weather information of an area where the selected terminal is located by using GPS information of the selected terminal. 71 shows such an example. The illustrated icon 7101 indicates that the selected terminal is located in the heavy rain alarm area.

Meanwhile, when the selected counterpart terminal moves to an area previously stored as a GPS coordinate value, the mobile terminal 100 may display an icon set when the coordinate value is stored. 72 shows such an example. For example, the mobile terminal 100 may display a school icon 7201 preset in the indicator area when the selected terminal moves to a preset "Suwon-si Yuljeon-dong Yuljeon Middle School".

Hereinafter, a method of providing location information according to privacy setting and intimacy according to an embodiment of the present invention will be described with reference to the drawings.

The mobile terminal according to an embodiment of the present invention may provide virtual location information or limitly display the received location information as the privacy protection function is set.

As illustrated in FIG. 82, the mobile terminal sets intimacy for each terminal or for each group (S8210). Here, the intimacy may refer to a criterion for setting the degree of disclosure of own location information for a specific terminal or a specific group.

For example, the intimacy can be selectively set from intimacy 1 to intimacy 10. Of course, the range and number of intimacy may be stored in the terminal by default or may be set by the user.

In the setting step S8210, the mobile terminal may set the intimacy according to the user's selection, or set the intimacy to correspond to the use frequency for each terminal or group (for example, the higher the use frequency, the higher the familiarity). .

In FIG. 83A, the intimacy setting for each terminal is shown, and in FIG. 83B, the intimacy setting for each group is shown.

The mobile terminal designates location information to be disclosed to other terminals for each intimacy set in the setting step S8210 (S8220). Here, the location information to be published by intimacy may be designated by the user or by default by the mobile terminal.

In addition, in the designation step S8220, the mobile terminal may designate an update period of the location information for each intimacy. For example, the higher the intimacy, the shorter the update period of the location information.

For example, as described in Table 1 below, location information to be published by intimacy may be designated.

Intimacy Disclosure Geolocation to be public Update cycle Intimacy 1 Private Identification Information Never Intimacy 2 Minimal Information Disclosure Identification and location 24 hours Intimacy 3 Basic Information Disclosure Identification, location, distance 10 hours ... ... Intimacy 10 Open all All information real time

Of course, the specifying step S8220 may be performed before the setting step S8210. In this case, location information to be published for any intimacy is first specified, and intimacy can be set for a specific terminal or group.

The mobile terminal transmits location information corresponding to the intimacy set for each terminal or for each group (S8230).

In the transmitting step S8230, the mobile terminal may transmit directly to the other terminal (or the second terminal) or transmit to the other terminal (or the second terminal) via the server.

In addition, when the mobile terminal has an intimacy 10 with the first and second other terminals, respectively, the first and second other terminals may be provided with location information of the intimacy 10.
