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

Administrative address information is hierarchically classified into a major classification area (for example, a country) / a first classification area (city, metropolitan or metropolitan) / a second classification area (city, (City, eup, myeon or ri) / second subdivision area (street, street or building name). For example, administrative address information can be selectively generated from a major classification to a small classification. At this time, the location information (in particular, the coordinate information) for each administrative address information is stored in the memory 160 or can be received from the outside via the wireless communication unit 110. [

The POI information may refer to a name or unique information set for a specific place. For example, the POI information may include information such as the name of "ㅇㅇ mart", "ㅇㅇ restaurant", "ㅇㅇ department store", etc. or the specific information such as "Gyeonggi-do restaurant", "recommendation data place", "weekend outing place" . At this time, the positional information (in particular, coordinate information) for each POI information may be stored in the memory 160 or may be received from the outside through the wireless communication unit 110. [

The setting name information may refer to a name or unique information set by a user for a specific place. For example, the setting name information may include "yesterday," "first date," "restaurant," "company," "house," "school, At this time, the position information (in particular, the coordinate information) for each set name information is stored in the memory 160 or can be received from the outside via the wireless communication unit 110. [

The relative position information may include information based on movement patterns such as a movement distance from one point to another, a movement time, a movement speed, a movement direction, a distance based on a specific point (for example, a position of a specific mobile communication terminal) The moving speed, the moving direction, and the like. At this time, the location information (in particular, coordinate information) of the specific mobile communication terminal may be stored in the memory 160 or may be received from the outside through the wireless communication unit 110.

In addition, resolution to be described later may refer to a degree according to the degree of detail of location-based information to be provided in providing the location-based information of the user to the counterpart communication terminal. Alternatively, the resolution may refer to a degree according to the degree of detail of the location-based information to be displayed in displaying the location-based information of the other communication terminal. In addition, the communication terminal according to the present invention may set a resolution for each of a plurality of external terminals or in common to at least one other communication terminal corresponding to a specific condition (for example, the same group, a certain radius, etc.) .

Hereinafter, with reference to FIG. 8, a method of providing location information in a communication terminal according to the present invention will be described in each step. 8 is a flowchart of a method for providing location information by a communication terminal according to an embodiment of the present invention. For convenience of explanation, it is assumed that the communication terminal referred to below can include at least one of the components shown in FIG.

As shown in FIG. 8, the communication terminal 100 receives the wireless communication signal from the external terminal through the wireless communication unit 110, and receives the location information about the external terminal (S810).

Here, the wireless communication signal may include at least one of a call signal and a message signal. For example, the call signal may include a voice call signal and a video call signal, and the message signal may include a multimedia message signal including a video message signal and a voice message signal, and a text message signal. Of course, the wireless communication signal may include data transmitted and received through a wireless Internet or a local area network.

Here, the location information may include coordinate information for an external terminal, or may include location-based information described above.

In the receiving step S810, the communication terminal 100 can receive position information on the external terminal from the external terminal or the server. At this time, the server can receive location information about the external terminal from the external terminal before transmission to the communication terminal 100. [ Further, when receiving the location-based information in the receiving step S810, the location-based information may be generated in the external terminal or the server.

In addition, in the receiving step S810, the communication terminal 100 may receive the wireless communication signal and the position information together through one data packet, or receive the wireless communication signal and the position information through the separate data packet, respectively have. For example, when received through one data packet, the communication terminal 100 can receive the wireless communication signal and the location information using the mobile communication module 112. [ The communication terminal 100 receives the wireless communication signal and the position information through the mobile communication module 112 or transmits the wireless communication signal through the mobile communication module 112 to the position The information module 115 may receive location information.

Here, the location-based information may indicate the location of the external terminal displayed on the map image by matching the location information received in the receiving step S810 with the map image. For example, assuming that the position information is coordinate information, if coordinates information for each point on the map image is stored in the memory 160 in advance or a map image on which coordinate information for each point is displayed from an external server, (100) can grasp points that match the coordinate information of the external terminal on the map image. Of course, in the generating step S820, not only the coordinate information but also the administrative address information, the POI information, the setting name information, or the relative position information may be used as the position information.

In the generating step S820, the communication terminal 100 may adjust the degree of detail of the location-based information according to the resolution set in the external terminal. For example, the resolution may be set from the first to the tenth grade for each terminal, and it is assumed that detailed position-based information is set from the first grade to the tenth grade. Conversely, detailed location-based information may be set from the tenth to the first tier. The resolution level may be changed by a user operation or may be changed at any time depending on the location of the external terminal. For example, when the positions of the communication terminal 100 and the external terminal are compared

The creating step S820 may be performed when the location-based information display function is selected by the user, or may be performed by default when there is received location information without any additional operation by the user.

Then, the communication terminal 100 displays the location-based information generated in the generating step S820 through the display unit 151 (S830).

The display step S830 may be performed when the location-based information display function is selected by the user.
