1 illustrates an internal block diagram of a portable communication device capable of transmitting and receiving advertisements and information based on a digital map according to the present invention.

The portable communication device according to the present invention includes a control unit 101, a timer 102, a power supply unit 103, a GPS module 104, a memory unit 105, a display unit 106, a communication unit 107, and a speaker 108. It may be made, including.

The controller 101 transmits the location of the corresponding device to the management server by matching the digital map partitioned on the basis of latitude and longitude based on the GPS location data of the corresponding device, and transmits the location of the corresponding device to the management server. Responsible for the overall control of the mobile communication device to receive and use advertisements and information.

The timer 102 selects the digital map stored in the memory unit 105 and the location information received from the GPS at predetermined time intervals or periodically, so that the utilization of advertisements and information can be arbitrarily adjusted.

The memory unit 105 stores data on the digital map, and stores mapping tables of latitude, longitude (UTM) coordinates, and digital maps. Platforms or applications that receive the message may be embedded. The memory unit 105 may be configured of an SRAM or a DRAM, or a flash memory that retains data even when power is cut off.

The wireless communication unit 107 may perform wireless communication with a remote management server. In the present invention, the corresponding device according to the location information of the corresponding device identified through the GPS module 104 and the digital map embedded in the memory. Is used as a means for notifying the management server wirelessly when a mobile station is moved from one area to another area, and used as a means for receiving advertisements and information of the area from the management server by wireless communication.

The display unit 106 and the speaker 108 are means for outputting advertisements and information of a corresponding region received from the management server as video signals and audio signals, respectively.

FIG. 2 is a diagram illustrating a UTM Grid Zone which is a reference for the digital map of the present invention, and FIG. 3 is a diagram illustrating the Republic of Korea divided into grid units based on the digital map according to the present invention, and FIG. The lattice of one illustrated region is divided and divided to display latitude and longitude.

The digital map disclosed in the present invention is based on the Universal Transverse Mercator Grid System (UTM), that is, the international trans-mercator coordinate system, and is reconstructed in units of detailed density by continent, country or city based on the UTM Grid Zone. The compartments are divided into grid units or overlapping circular units.

The digital map of the present invention has no data on the actual map and only has a latitude and longitude value in units of partitions. In the case of division by grid unit, only the latitude and longitude information of the vertices in the diagonal direction of the unit grid cell is included, and in the case of partitioning by the circular unit, only the latitude and longitude information of the center point of the unit circular cell is included.

The reason for this configuration is as follows.

In other words, for example, considering a grid of about 300 km in width and 400 km in length, the grid is divided into unit grids of 1 km in width and 300 in width, 400 in length, that is, 120,000 grids. Only the latitude-longitude information of the two vertices of the diagonal of each grid can obtain accurate information about the region, and the map data of the region is not necessary. When the digital map is configured in this manner and information is input to the mobile device, when the entire Korea is digitally mapped in grid units of 1 km, the size of the digital map is only 1 megabyte. In particular, if you delete unnecessary mountains and seas, the digital maps of continents and countries will be considerably smaller. This will fundamentally solve the load on GPS and data servers where GPS-embedded devices are concentrated and efficiently implement geo fence services. To make it possible.

A digital map of these criteria will be described with reference to South Korea as an example.

Referring to FIG. 2 again, based on the UTM coordinate system, Korea belongs to the 51S, 51T, 52S, and 52T zones when combined with the two Koreas, and the Korean continent belongs to the 52S zone (200). Yes.

If you repartition Korea again in grid units, you will see in Figure 3. The inland mark boundary of the Republic of Korea shown in FIG. 3 is shown for convenience of description and the information about the map is omitted in the actual digital map.

The unit grid shown in FIG. 3 is 10 km long and long, and is displayed in a grid of approximately 1,100 when only inland is partitioned. If it is divided into 1km of unit grid, it can be partitioned into 110,000 grids, and if it is divided into 0.5km, it can be partitioned into 440,000 grids. It does not include the data of the actual map and has a latitude and longitude value that is location information of each grid, so the data capacity is very small.

FIG. 4 partitions the compartment shown in FIG. 3 into 1 km horizontally and vertically, partitioning the entire grid into approximately 110,000 grids (inland only) to display a region of a portion of the display grid 300. Specifically, the unit lattice division and latitude and longitude of Hapjeong-dong and its neighboring areas in Mapo-gu, Seoul, Korea shall be indicated.

That is, the display grid 300 of FIG. 3 is repartitioned by 1 km horizontally and vertically as shown in FIG. 4, and the digital map of the grid partition shown in FIG. 4 is E126 ° 59′22.31 ″ at latitude E126 ° 52′7.41 ″. And the latitude and longitude values of N37 ° 36'53.05 "to N37 ° 30'55.88" are shown as an example divided by 1 km unit lattice.

When the user of the mobile communication device moves from the A position to the B position, the user is precisely located at the B position (E126 °) at the telephoto elementary school (E126 ° 54′4.6 ″, N37 ° 33′38.28 ″) at the A position. Suppose you are moving to 54'17.75 ", N37 ° 33'28.63".

Where A is the two vertices of the grid, a (E126 ° 53′28.39 ″, N37 ° 34′10.7 ″) and d (E126 ° 54′38.88 ″, N37 ° 33′38.23 ″) or b (E126) Latitude and longitude range of ° 54'38.88 ", N37 ° 34'10.7") and c (E126 ° 53'28.39 "N37 ° 33'38.23"), where B position is the two vertices of the grid in the diagonal direction c (E126 °) 53′28.39 ″ N37 ° 33′38.23 ″) and f (E126 ° 54′38.88 ″, N37 ° 33′5.76 ″) or d (E126 ° 54′38.88 ″, N37 ° 33′38.23 ″) and e (E126 ° 53'28.39 ″ N37 ° 33′5.76 ″), and when the user moves from position A to position B, the management server is notified by the GPS location information. Local information is transmitted to the mobile communication device.

In other words, the portable communicator checks its location B using the GPS module 104, and if the location B has been moved from the location A where it was previously, the mobile communication device sends it to the remote management server. A notification is made that the position A has moved from the position A to the position B. The management server receives the information that the user has moved to location B, the information of the region desired by the user (relevant information of the region, such as a tourism / leisure / local event), other friends using the same application, or a restaurant / sightseeing, etc. Will convey information such as

Of course, the information may not want the user to receive it at a specific time, and if it is the first visited area, the user may agree to the reception of the information by selecting the category of information he / she needs.

If the amount of information to be posted gradually increases, the information may be provided in a separated form. If the amount of information is not large, the information may be listed on one page.

Now, people who want to provide information to users through advertisements or push of specific information in the area can enter the area where the map is set up as above, then select the grid or set the area by drag and drop. You can implement a business model by selecting categories for which you want to push an advertisement or information, then selecting a period of time for which you want to provide information and paying for it.

The device incorporating the digital map and the GPS receiver according to the present invention is a server at a time when a position movement occurs periodically or every time the user moves (set by the user such as 30 seconds / 1 minute / 10 minutes) or using GPS. It is possible to provide their own location, and receive information prepared in the area through SMS / browser / application, etc., and to provide the service in various ways in addition to the above-described specific process.

Those who want to register advertisement / public information in more detail with the above-described technology, select and publish a single or plural areas to be provided on the grid map by setting the same as those embedded in the digital devices of the users. It can be posted with additional information such as period.

In addition, in order to prevent unnecessary waste such as unnecessary walking and vehicle transfers, when the user first raises his or her position, GPS is used to provide the current moving speed, so that general walking is used among the types of advertisements. And it may be provided to select whether or not to include the movement of the vehicle.

In addition, in the case of the use of the advertisement and information reception according to the present invention, all relevant reception information such as various advertisements at the local unit and related discount coupons / coupons / direction information, guidance on public / regional information at public institutions, public relations, policy guidance, etc. It is also possible to increase the utilization of the information by using a messaging platform to deliver to other friends.

In addition, when the user moves out of the country and moves abroad, the user must download and install the digital map file of the corresponding country in advance or, in the case of a terminal having a large memory, download the digital map of the world and embed it in his / her terminal.
