For convenience of description, it is assumed that the mobile terminal mentioned below includes at least one of the components shown in FIG. 1.

3 is a flowchart schematically illustrating a message receiving method in connection with the present invention.

The wireless communication unit 110 of the mobile terminal 100 receives the current location UFID for the current location of the mobile terminal 100 (S310). The memory 160 of the mobile terminal 100 stores the current position UFID as the terminal UFID (S320). The wireless communication unit 110 receives a message including a target UFID for the target location (S330). The controller 180 determines whether the terminal UFID and the target UFID match (S340). If it is determined that the controller 180 matches, the display unit 151 displays the contents of the message (S350). If it is determined that the controller 180 does not match, the memory 160 discards the message (S360).

The mobile terminal 100 of the present invention may receive terrain identification information that distinguishes a particular terrain or location from another object. The terrain identification information for identifying a specific terrain or location may include conventional address system information.

In the present invention, UFID (Unique Feature Identifier) can be used as terrain identification information that can distinguish a specific terrain or location from other objects.

UFID is an electronic identifier for artificial and natural features such as buildings, roads, bridges, and rivers. In other words, UFID is a concept similar to a social security number given to a person. For example, if a new plant enters Jamsil-dong, Songpa-gu, Seoul, UFID may be given as "2 21 11061 4611 3591300300 00099007652".

The UFID number contains various information such as the correct administrative district (2 21 11061), the feature classification code of the factory (4611), the leaf number (3591300300), the feature identifier for each organization (0009907652), and the error check (7). . The 32-digit UFID can be stored in ASCII or Binary format. Furthermore, UFIDs are assigned to all features included in national geographic information, including buildings, cultural properties, railroads, roads, rivers, lakes, coasts, administrative boundaries, survey control points, cadastral and contour lines.

Therefore, if the UFID utilization system is established, it is possible to search for and output various kinds of attribute information of the desired type with only individual identifiers such as items, locations, administrative districts, map maps, and management agencies. In fact, UFID can be used as an essential location identifier for future location-based services (LBS) because location can be determined as a geographical identifier rather than a coordinate.

In addition, national infrastructure can be integrated and managed by using UFID as the main searcher in the database maintained by the feature management institution. By avoiding duplication of information on the same feature into separate managed databases, information can be kept consistent and investments can be avoided when collecting and entering information.

4 schematically illustrates the concept of UFID in relation to the present invention.

In the figure, UFID is represented by alphabets and numbers rather than 32 digits, and the present invention is not limited to this UFID scheme.

In the present invention, the UFID management center 400 is an organization for granting a single ID at the national level, and aims to share information. The UFID management center 400 manages an operation system and assigns UFIDs, which are unique IDs, to specific terrain and location. This UFID information is stored in the UFID management center 400.

In the figure, the object identified by the UFID is shown. For example, road 410 is assigned an UFID of 'A0010000002', railroad 420 is assigned an UFID of 'B0020000001', aviation 430 is assigned an UFID of 'C0030000005', and other features. Again UFIDs are identified that identify each in the same way.

The mobile terminal 100 of the present invention may be in a fixed position or may be in a mobile state. The mobile terminal 100 needs to check the UFID corresponding to the current location. Accordingly, the wireless communication unit 110 of the mobile terminal 100 receives the UFID for the feature currently located.

The term 'current location UFID' as used herein is used as the UFID for the current location where the mobile terminal 100 is located.

5 is a diagram illustrating a method of receiving a current location UFID in accordance with the present invention.

When the mobile terminal 100 is located at a specific point in time, the mobile terminal 100 may receive the current location UFID in various ways. First, the current location UFID for the current location may be received through the GPS satellite 510. In this case, the GPS satellite can accurately identify various locations on the ground, and can use various UFID information stored in the UFID management center 400 described above. The GPS satellite 510 may transmit the current location UFID based on the accurately determined position of the mobile terminal 100, and the wireless communication unit 110 of the mobile terminal 100 receives the transmitted current location UFID.

Alternatively, the current location UFID may be received via the Wi-Fi server 520. The mobile terminal 100 may receive the current location UFID via the Wi-Fi server 520 if the Wi-Fi function is present and can access the Wi-Fi server. In this case, the Wi-Fi server 520 may transmit current location UFID information for the exact location where the terminal 100 is located.

Alternatively, the current location UFID may be received via the terminal base station 530. The mobile terminal 100 may connect with the base station 530 for the call reception. In this case, the terminal base station 530 may determine the current position of the terminal 100 and transmit the current position UFID through the transmission / reception signal from the terminal 100.

When obtaining the current location UFID via the Wi-Fi server 520 or the terminal base station 530, although the current location UFID for the exact location where the terminal 100 is located may be transmitted, other schemes exist. That is, when the Wi-Fi server 520 or the terminal base station 530 is fixed, the server 520 or the base station 530 may have a corresponding UFID. In this case, the UFID that the server 520 or the base station 530 has can be transmitted to the terminal 100 existing in the coverage of the server 520 or the base station 530 as the current location UFID. This approach is useful when the mobile terminal 100 is in a location where the UFID is not correctly assigned. Each of the plurality of servers 520 or base stations 530 divides the spatial area into a coverage area that it can cover. Accordingly, the terminal 100 generally belongs to one coverage area among several coverage areas. By assigning the current UFID of each coverage area to the UFID of the corresponding server 520 or the base station 530, the UFID can be assigned even where the mobile terminal 100 is located.

When the wireless communication unit 110 receives the current location UFID in the same manner as described above, the controller 180 stores the received current location UFID as the terminal UFID in the memory 160. The terminal UFID may be changed according to the location of the mobile terminal 100 as the UFID information for the mobile terminal 100.

The wireless communication unit 110 receives the current location UFID from the outside as described above. If the mobile terminal 100 is in a fixed position, it may not be necessary to newly receive the current position UFID. However, when the mobile terminal 100 is in the mobile state, it is necessary to newly receive the current position UFID. Accordingly, the mobile terminal 100 may periodically receive the current location UFID. Alternatively, the mobile terminal 100 may determine the movement state of the mobile terminal 100 and receive the current location UFID only when the location is changed.

When receiving the new current location UFID, the controller 180 of the mobile terminal 100 updates the terminal UFID using the new current location UFID. In this way, the terminal UFID is set to be kept as the latest UFID as the UFID for the terminal 100.

FIG. 6 is a diagram illustrating a manner in which a message server transmits a target UFID according to the present invention.

In the figure, the message server 600 transmits a message to the various terminals 100a to 100d. The message content may include content that needs to be announced to the terminals located nearby. For example, in case of an emergency such as a river flood, the message server 600 may transmit a content such as a river flood to neighboring terminals.

The message server 600 may be located at various places. For example, the message server 600 associated with the flood can be located by the river, and in the event of a fire, it can be located at the fire station.

The message includes UFID information and transmits the message to the terminals 100a to 100d. The message server 600 may send a message to all terminals that the message server 600 can search. The message server 600 may periodically search for the presence of terminals located nearby, and accordingly, send a message to the retrieved terminals.

Alternatively, instead of sending a message to all discovered terminals, the message may be sent only to terminals that wish to receive message service. For example, if the terminal 100a, 100b, 100c is set to receive a message service and the terminal 100d is set to reject it, the message server 600 may only send messages to the terminal 100a, 100b, 100c. May be transmitted.

The message sent by the message server 600 includes UFID information. The reason why such UFID information is included is to transmit a message only to terminals located in a specific area (target) where the message can be checked.

The UFID information is information about the target UFID which is the UFID corresponding to the target position. There may be one target location, but there may be multiple target locations. Accordingly, the target UFID information may exist in the UFID list.

7 illustrates the structure of a message in accordance with the present invention.

The structure of the message related to the present invention includes a target UFID information 710, a Due date 720 indicating an activation period, and a message default structure 730 including message contents.

The target UFID information 710 may include a plurality of target UFIDs as described above. Accordingly, the target UFID information 710 includes UFID1 710a, UFID2 710b, and other UFIDs 710c representing each target UFID. Each target UFID corresponds to the UFID of the particular terrain for which a message is to be received. This target UFID is used later when determining whether or not the terminal UFID matches.

Due date (720) is information on the validity period of the message is active. Accordingly, the due date 720 includes information on the expiration date desired by the message producer, and the expiration date information included in the due date 720 is used by terminals receiving the message.

The message default structure 730 may include various information included by default in the message. The message default structure 730 may include various information such as message content, message transmission date, message sender, and the like included in the message.

8 is a flowchart schematically illustrating a message storing method associated with an activation period of a message in accordance with the present invention.

As described above, a due date 720 is included in the message structure that includes the activation period information of the message. Accordingly, the mobile terminal 100 receiving the message may use information about the corresponding activation period. Thus, the message may be stored in memory 160 during the activation period but discarded if not during the activation period. By using the activation period information of the message, it is possible to prevent the message from being stored regardless of the user's intention.

Let's take a quick look at how messages are stored, relative to how long messages are active.

First, the wireless communication unit 110 of the mobile terminal 100 receives a message (S810). After determining whether the target UFID and the terminal UFID match after receiving the message, the controller 180 determines whether the message is within an activation period (S820). If the message is within the activation period, the message is stored in the memory 160 (S830). If the message is not the activation period, the message is discarded (S840).

The mobile terminal 100 of the present invention needs to receive a new location UFID when it is moving. When moving, the new position UFID is received because the UFID at the previous position and the UFID at the new position are different from each other.

FIG. 9 is a diagram illustrating a method of updating a terminal UFID when the terminal moves in accordance with the present invention.

In the figure, regions to which different UFIDs are assigned are shown. That is, the first area 910 to which "A0010000007" is assigned as the UFID, the second area 920 to which "A00100000002" is assigned as the UFID, and the third area to which "A0010000003" is assigned to the UFID are shown. If the terminal 100 exists in the first area 910, "A0010000007" is stored as the terminal UFID of the terminal corresponding to the first area 910. If the terminal 100 exists in the second area, the second area 920 ), "A0010000002" is stored as the terminal UFID of the terminal.

In the figure, the mobile terminal 100 is shown moving from the second area 920 to the third area 930. Since different UFIDs are assigned to the second area 920 and the third area 930, there is a need for updating the terminal UFID stored in the mobile terminal 100 as the mobile terminal 100 moves. Accordingly, the mobile terminal 100 has been stored as "A0010000002" as the terminal UFID in the second area 920, but is updated to "A0010000003" with the terminal UFID as it moves to the third area 930.

In the updating process, the wireless communication unit 110 of the mobile terminal 100 periodically receives the current position UFID and updates the terminal UFID when the current position UFID changes according to the movement of the terminal. It is also possible to receive the current location UFID only when the terminal has moved.

When the wireless communication unit 110 of the mobile terminal 100 receives the message, the controller 180 analyzes the target UFID lists included in the message. According to the analysis result of the controller, it is determined whether one of the target UFID lists and the terminal UFID stored by the terminal 100 match.

According to the determination result of the controller 180, when the target UFID and the terminal UFID match, the content of the corresponding message may be displayed. That is, since the message is set so that only the terminal located in a specific terrain can read the contents, the message can be read only when the target UFID and the terminal UFID match.

On the other hand, according to the setting of the control unit 100, even if the target UFID does not necessarily match the terminal UFID, if it is determined that the feature corresponding to the target UFID and the feature corresponding to the terminal UFID are close or similar, the message is sent. It can also be set to display.

10 illustrates the display of a message in connection with the present invention.

According to the determination result of the controller 180, when the target UFID included in the message and the terminal UFID match, the message content may be displayed on the display unit 151.

FIG. 10A illustrates an operation of notifying reception of a message when the target UFID and the terminal UFID match.

In the figure, although shown in the form of general message reception, it is also possible to inform the reception of the message in the form of an emergency message or a summary of the content of the message.

10B is a diagram of displaying the content of the corresponding message on the display unit 151.

The message area 1020 of the display unit 151 displays information of the message, sender, and the like. In the figure, by way of example, the content of a message informing of an emergency is displayed in the message content area 1022. In addition, information such as a source and a time may be displayed in the source region 1024 to inform the source.

In another aspect of the present invention, the message may include information of the activation period as well as UFID information. Accordingly, the displayed message may display information indicating the activation period in the validity area 1026. In the figure, since 8/25 12:00 is the activation period, the message may be deleted from the memory 160 when the period is exceeded.

The present invention may transmit the received message to another terminal.

The wireless communication unit 110 of the mobile terminal 100 may not only receive a message from the outside but also transmit the received message to a neighboring terminal. Through this function, neighboring terminals may also share necessary message information.

In the present specification, the description is limited to UFID, but the present invention is not limited to UFID. For example, if there is a system for identifying features, the present invention may be applied without being limited to the names.

In addition, according to an embodiment of the present invention, the above-described message receiving method may be embodied as a processor readable code on a medium in which a program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
