5 is a block diagram illustrating a configuration of a user terminal for location-based services according to an embodiment of the present invention.

The user terminal 500 for a location based service according to an embodiment of the present invention may be a client and may include a storage unit 510, a search unit 520, a communication unit 530, and a GPS device 540 have.

However, the user terminal 500 shown in FIG. 5 is only one embodiment of the present invention, and various modifications are possible based on the components shown in FIG. For example, the user terminal 500 may further include a user interface for receiving a command or information from the user. In this case, the user interface may be an input device such as a keyboard, a mouse, or the like, but may be a graphical user interface (GUI) represented in an image display device.

The storage unit 510 may store block index information on a block area generated by dividing a geographical area on a block basis, and target block index information on a target block area including a context object in the geographical area.

For example, when an application for the location-based service is installed in the user terminal 500, the user terminal 500 may store the block index information and the target block index information together with the installation of the application.

At this time, the block index information stored in the user terminal 500 is the same as the block index information stored in the server, and the target block index information stored in the user terminal 500 is the same as the target block index information stored in the server described above.

That is, the user terminal 500 and the server share the same generated block area for the same geographical area, and share the same block index information for the corresponding block area. Also, for the same geographical area, the user terminal 500 and the server described above share the target block index information about the target block area including the context object in the corresponding geographical area.

On the other hand, the location information of the situation recognition object is not basically stored in the user terminal 500 or the storage unit 510. That is, when the application for the first location-based service is installed in the user terminal 500, the location information of the context is not included in the application.

However, when using the application, the user terminal 500 or the storage unit 510 may store the target key information when receiving the target key information including the location information of the situation recognition target from the server. When the location information of the situation recognition target is stored in the user terminal 500 from the beginning, the resources used by the user terminal 500 and the above-described server to update the location information of the situation recognition target may become unnecessarily large, In the case of the terminal 500, the battery may be consumed abruptly and the file size of the application may become too large. Accordingly, in order to minimize the number of times of interworking between the user terminal 500 and the server, the user terminal 500 may initially store only minimum information, and additionally store the received information as the location-based service proceeds.

In addition, the storage unit 510 may include a nonvolatile memory device such as a cache, a read only memory (ROM), a programmable ROM (PROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), and a flash memory Or a storage medium such as a CD-ROM, a hard disk drive (HDD), or a volatile memory device such as a random access memory (RAM).

The search unit 520 searches for at least one target block area corresponding to a target block area including a context area of a user block area including a location of the user terminal 500 and a neighboring block area adjacent to the user block area, It is possible to judge whether or not it exists. The determination operation of the search unit 520 may be based on location information of the user terminal 500, block index information on the block region, and target block index information on the target block region including the context recognition target.

The search unit 520 may determine whether a target block area exists whenever location information of the user terminal 500 is received through the GPS device 540. [ If the GPS device 540 is in the on state, the search unit 520 can receive the position information every N seconds (for example, 45 seconds) and perform the determination operation.

A detailed description of the determination operation based on the area search of the search unit 520 will be described later.

The communication unit 530 may transmit the block index information about the target block area to the server when at least one target block area exists. The communication method used in the communication unit 530 may be a TCP / IP method.

Also, the communication unit 530 can receive, from the above-described server, the object key information including the position information of the situation or object located in the target block area. At this time, the context to be located in the target block area can be extracted from the server based on the block index information about the target block area and the location information of the context information in the geographical area.

In addition, the communication unit 530 can receive, from the server, target key information including positional information and seed information of the final situation-aware target. Here, the final context awareness object may be selected differently depending on the location based service among the context awareness objects located in the target block area, and the seed information may be provided to receive contents related to the final context awareness object. In this case, the communication unit 530 may transmit the content request signal to at least one of the above server, the final context aware object, and the final context aware object based on the seed information.

Hereinafter, a more detailed description will be given with reference to FIG. 6 and FIG.

FIG. 6 is a flowchart illustrating an operation of transmitting and receiving information between a server and a user terminal for location-based services according to an exemplary embodiment of the present invention, and FIG. Fig.

The server stores the target key information including the location information of the context information in the geographical area and the block index information of the block area generated by dividing the corresponding geographical area in block units in step S601, The target block index information for the target block area including the information and the context recognition target is stored (S602).

Referring to the user terminal of FIG. 7, a plurality of block areas A to I generated by dividing a predetermined geographical area into blocks are shown. A user block area E including the position of the user terminal 701 and peripheral block areas A to D and F to I arranged adjacent to the user block area E are shown. The area marked by the check (V) means a target block area (A, B, D, H) including a situation recognition object.

The user terminal determines the user block area E and the neighboring block areas A to D based on the location information of the user terminal, the block index information on the block areas A to I, and the target block index information on the target block area. F to I exist in the target block area (S603).

According to the determination result based on the area search, the target block areas A, B, D, and H exist (S604).

Since the target block area exists, the user terminal transmits the block index information for the target block areas (A, B, D, H) to the server (S605). For reference, the user terminal does not transmit the location information of the user terminal to the server.

The server updates various information stored in the database periodically, aperiodically, or whenever a specific event occurs (S606). An information update can be made at a timing different from that shown in Fig.

Referring to the server side in FIG. 7, a plurality of block areas A to I generated by dividing a geographical area that is the same as the geographical area referred to on the user terminal side into blocks are shown. Situation awareness objects 702 to 706 located in the target block areas A, B, D, and H among the context awareness objects in the geographic area are shown.

The server extracts the context aware objects 702 to 706 located in the target block area based on the positional information of the context in the geographic area and the block index information on the target block areas A, B, D, and H S607).

According to an example, the server transmits target key information including location information of the extracted context-aware objects 702 to 706 to the user terminal. The position of the situation aware objects 702 to 706 is shown as one point in FIG. 7, but in the present invention, the position information may be region information without being limited to one point information as shown in the figure.

Through this, the user terminal does not transmit the location information of the user terminal to the server, but can indirectly recognize the location of the situation located near the user terminal.

According to another example, the server may be configured to receive the location information of the final situation, which is selected differently according to the location-based service among the situation-aware objects 702 to 706 located in the target block area, And transmits the target key information including the seed information to the user terminal (S608).

At this time, the final situation recognition object is selected in the user terminal. For example, the user terminal can select the final situation or target located at the minimum distance based on the location information of the user terminal and the location information of the context to be located in the target block area.

The user terminal generates a content request signal based on the seed information (S609), and transmits the content request signal to at least one of the server, the context aware object, and the management server (not shown) for the context aware object.

Accordingly, the user terminal does not transmit the location information of the user terminal to the server, but can indirectly recognize the location of the user terminal located near the user terminal, as well as transmit the content request signal (final) Related contents can be provided.

By using the server and the user terminal according to an embodiment of the present invention described above, it is possible to smoothly provide various location-based services or geopansing services without any problems regarding traffic load, battery consumption, information update, and the like. In addition, since the server does not collect the location information of the user terminal, the personal information problem does not occur.

However, according to an embodiment of the present invention, there may be a considerable number of final context objects, and in this case, the efficiency of the user terminal and the server may deteriorate. Therefore, the following embodiment is proposed in order to further reduce the number of final context awareness objects.

In this case, the communication unit 930 may transmit the cell index information about the final target cell region to the server described above, and receive the target key information including the location information of the situation target located in the final target cell region from the server have. At this time, the context to be located in the final target cell area may be extracted from the server based on the cell index information about the final target cell area and the location information of the context information in the geographical area.

Hereinafter, a more detailed description will be made with reference to FIG. 10 and FIG.

FIG. 10 is a flowchart illustrating information transmission / reception and operation in each configuration between a server and a user terminal for location-based services according to another embodiment of the present invention. FIG. And Fig.

The server comprises: target key information including position information of a situation or object in a geographical area; block index information on a block area generated by dividing the geographical area into blocks; and a cell area (S1001), and the user terminal stores the target block index information for the target block area including the top block index information and the context recognition target (S1002).

Referring to the user terminal side shown at the upper left of FIG. 11, a plurality of block areas A to I generated by dividing a predetermined geographical area into blocks are shown. Although nine cell regions generated by dividing each block region into cell units are shown, the number of cell regions may vary. A user block area E including the position of the user terminal 1101 and peripheral block areas A to D and F to I arranged adjacent to the user block area E are shown. The area marked by the check (V) means a target block area (A, B, D, H) including a situation recognition object.

The user terminal determines the user block area E and the neighboring block areas A to D based on the location information of the user terminal, the block index information on the block areas A to I, and the target block index information on the target block area. F to I exist in the target block area (S1003).

According to the determination result based on the area search, the target block areas A, B, D, and H exist (S1004).

Since the target block area exists, the user terminal transmits block index information for the target block areas (A, B, D, H) to the server (S1005). For reference, the user terminal does not transmit the location information of the user terminal to the server.

The server updates various information stored in the database periodically, aperiodically, or whenever a specific event occurs (S1006). An information update can be made at a timing different from that shown in Fig.

Referring to the server side shown at the upper right of FIG. 11, a plurality of block areas A to I generated by dividing the same geographical area as the geographical area referred to on the user terminal side are shown. For example, each cell area in the E block area corresponds to e1 to e9 in order. The target cell areas a6, a7, b5, d4 and h9 including the context aware objects in the target block areas A, B, D and H are shown.

The server calculates target cell areas (a6, a7, and a7) including the context-aware objects in the target block area based on the location information of the situation-aware object in the geographical area and the block index information on the target block areas , b5, d4, h9) are extracted (S1007).

The server extracts the target block areas A, B, D (a, b, d, and h) including the cell index information for the extracted target cell areas a6, a7, b5, , H) to the user terminal (S1008). In order to notify the user terminal of which target cell area is included in which target block area, the server transmits together information in a matching or inclusion relation with each other.

In this way, the user terminal does not transmit the location information of the user terminal to the server, but can indirectly recognize the area (the target cell area) of the cell unit including the context to be located around the user terminal.

Referring to the user terminal shown in the lower left of FIG. 11, it can be seen that the user terminal 1101 is located in the e5 cell area. (1) to (5) between the target cell areas a6, a7, b5, d4, and h9 and the user terminal 1101 are also shown.

Since the target cell areas a6, a7, b5, d4 and h9 are two or more, the user terminal compares the cell index information for the target cell area a6, a7, b5, d4 and h9 with the location information of the user terminal. And determines the final target cell area (indicated by *, b5) located closest to the user terminal (S1009). Since the user terminal does not transmit the location information of the user terminal to the server, the operation of determining the final target cell area is performed at the user terminal.

The user terminal transmits cell index information on the determined final target cell area (b5) to the server (S1010).

The server updates various information stored in the database periodically, aperiodically, or whenever a specific event occurs (S1011). An information update can be made at a timing different from that shown in Fig.

Referring to the server side shown in the lower right of Fig. 11, the context aware object 1102 located in the final target cell area b5 is shown. 11, a plurality of context aware objects may exist in the final target cell area b5.

The server receives the cell index information for the final target cell region b5 determined by the user terminal from the user terminal and extracts the context-aware object located in the final target cell region b5 (S1012).

According to an example, the server transmits target key information including position information of a situation-aware object located in the final target cell area b5 to the user terminal. Although the position of the situation recognition object is shown as a single point in FIG. 11, in the present invention, the position information may be area information, not limited to one point information as shown in the figure.

Through this, the user terminal does not transmit the location information of the user terminal to the server, but can indirectly recognize the location of the situation located near the user terminal.

According to another example, the server may further include a target key including seed information for receiving the content related to the final situation-aware target and the final situation target, which is differently selected according to the location- Information to the user terminal (S1013).

The user terminal generates a content request signal based on the seed information (S1014), and transmits the content request signal to at least one of a server, a final context aware object, and a management server (not shown) for a final context aware object.

Accordingly, the user terminal does not transmit the location information of the user terminal to the server, but can indirectly recognize the location of the user terminal located near the user terminal, as well as transmit the content request signal (final) Related contents can be provided.

By using the server and the user terminal according to another embodiment of the present invention described above, it is possible to smoothly provide various location-based services or geopansing services without problems related to traffic load, battery consumption, information update, and the like. In addition, since the server does not collect the location information of the user terminal, the personal information problem does not occur.

3, 5, 8, and 9 may be configured as a 'module'. The term 'module' refers to a hardware component such as software or a Field Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC), and the module performs certain roles. However, a module is not limited to software or hardware. A module may be configured to reside on an addressable storage medium and may be configured to execute one or more processors.
