The present invention relates to a location-based service system, and more particularly, to a method and apparatus for displaying location information using a regional geographic code.

1 is a conceptual diagram of a location-based service system.

The system for the location-based service is composed of a location-aware node, a location-unaware node, a location server, and a user as shown in FIG. 1. A user requests a service to a location server and checks location information. A location server provides a user with various location-based services and maintains location-based service-related information. Location nodes, which are targets for providing location information, are classified into location-aware devices and location-aware devices. Location-aware nodes are objects that can identify locations in geographic space through location technology, such as GPS, and user input, and location-aware nodes are objects that cannot identify locations.

The conventional method of displaying location information is a method of displaying coordinates of a location recognition node in the location-based service system of FIG. 1. Therefore, the conventional method of displaying location information does not represent location-aware nodes in order to provide location-based services to location-aware nodes. In addition, in the case where the space including the location recognition node is a local space having its own spatial characteristics, when the location of the location recognition node is displayed, the above unique spatial characteristics may not be reflected.

Therefore, the conventional method of displaying location information cannot accurately reflect the location of the location-aware node and the location of the location-aware node, and is easy to apply to location-based services in an integrated environment including both local and regional spaces. In addition, there is a problem that requires a high cost because the location recognition device must be added to the system to apply to the integrated environment.

The technical problem to be achieved by the present invention is to provide location-based services to location-aware nodes centered on location-aware nodes, and to display location information that can provide accurate services at low cost in an integrated environment of global and regional spaces. To provide a method.

Another object of the present invention is to provide a device for displaying location information to which the above method for displaying location information is applied.

In order to solve the above technical problem, the present invention converts a geographical address code represented by a longitude, altitude, latitude corresponding to an arbitrary position into a geographical code represented by a coordinate and a predetermined range corresponding to the geographical address code. Determining whether spatial characterization corresponding to the geographic code is necessary; and converting the geographic code into a regional geographic code including the spatial characteristic when the spatial characterization is required.

In order to solve the above other technical problem, the present invention converts a geographical address code represented by a longitude, altitude, and latitude corresponding to an arbitrary position into a geographical code represented by a coordinate and a predetermined range corresponding to the geographical address code. A geographical code conversion unit for determining a spatial feature corresponding to the geographical code; and a local geographical code for converting the geographical code into a regional geographical code including the spatial characteristic if the spatial characteristic is required. It includes a conversion unit.

Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention.

Such location-based services are classified into a form in which the user and the location node are separated and a form in which the user and the location node are combined. The separated type of service is a type of service that requires location information for a location node, and the combined type of service becomes a service type using the location information when the user has location information. In addition, the separated service is divided into a request service type in which a user directly requests a location node and a notification service in which the location node informs the user by an arbitrary rule.

2 is a flowchart of a location-based service to which the present invention is applied.

FIG. 2 illustrates a scenario of providing a location-based service in the form of a request service that requires a user to directly locate a location node in the system of FIG. 1, and uses a geographical code to locate location-aware nodes and location-aware nodes. It shows you what information you provide. The location information used here uses a geographic code or a geographical code.

When a user requests a location request service for a location-based service from a location server, the location server searches for a location node through information managed and maintained, and delivers a service request message to the location node.

It is assumed that the location node can predict the location of the location node by updating the location information periodically or per service response. The location node receiving the service request message forwards the location information to the location server.

The location server delivers to the user. When the location server delivers a service response message to the user, other application data may be added according to the user's characteristics and requirements.

Figure 2a shows a location-based service process for a location-aware node, where location node A has location information and provides location information directly to the user, while Figure 2b shows a location-aware node. Since the location-aware node does not have location information by requesting a location-based service, a service response message may be delivered to the location-aware node, and the location-based service may be added by adding location information of the location-aware node.

3 is a flowchart illustrating another scenario of FIG. 2.

3 shows a scenario of a location-based service type of notification service type. The notification service informs the user of the location information when needed according to any rule of the location node.

Since the location aware node has location information as shown in FIG. 3a, the service notification message is directly transmitted to the location server. The location server then delivers the received service notification message to the user based on the service profile of the user.

Since the location unrecognized node does not have the location information as shown in b) of FIG. 3, the service notification message is transmitted to the location recognition node, and the location recognition node adds the geographical code to the location server. Based on this basic structure, location-based services are provided.

In the present invention, a Geographical Code (GGC) is a code representing a location and a code representing a location by coordinates and ranges.

In addition, a local geographic code (Local GGC) is a code representing a location by giving a local characteristic to a geographic code, and has the same representation rules as the geographic code.

In addition, the location node is a target for providing a location-based service having a network function, and is composed of a location-aware node having location information and a location-unaware node having no location information. .

In addition, a location server is a server that manages and maintains location information of a location node, and provides various services using location information to a user.

In addition, the geographic address code (GeoAddress) is location information expressed in longitude, altitude, and latitude in a geographic space.

Meanwhile, the fixed address code (AbsAddress) is location information obtained by converting a geographical address code through an arbitrary rule, and the relative address code (RelAddress) is location information expressed relatively through a fixed address code.

4 is a block diagram of the present invention.

The geographic code conversion unit 410 converts a geographic address code expressed in longitude, altitude, and latitude corresponding to an arbitrary position into a geographic code expressed in coordinates and a predetermined range corresponding to the geographic address code.

The geographic code conversion unit 410 determines a fixed address code or a relative address code using a GeoCodeSystem function and generates a geographic code after determining a scale of a range. The geographic code conversion unit 410 is in charge of geographic code processing. The geographical code converter 410 is responsible for analyzing and generating the geographical code. The geographical code conversion unit 410 generates a geographical code by performing a function of converting a geographical address code and a fixed address code by having a function of a geocode system.

The local space control unit 420 determines whether the spatial feature corresponding to the geographical code is required.

If geographic code assignment is required, the geographic code conversion unit 430 converts the geographic code into a geographic geographic code including the spatial property. Preferably, the local geographic code conversion unit 430 generates a local geographic code using a local geocode system function.

In FIG. 4, if it is determined that the spatial characteristics assigned to the regional geographic code are required by the geospatial control unit 420, the geographical code converting unit 410 and the geographical geographic code converting unit 430 convert the regional geographic code into the geographical code. The conversion process can be performed.

FIG. 5 is a block diagram of a location node device including the data processor 400 of FIG. 4.

The data processor 500 processes the transmitted and received data according to the characteristics of the application program. In addition, the data processing unit 500 includes a geographical code conversion unit 510 and a geographical code conversion unit 530 for location-based services.

The geographic code conversion unit 510 generates, maintains, and manages geographic codes used in a wide area.

The local space controller 520 determines whether it is necessary to give a spatial characteristic to the geographical code. In addition, the local space controller 520 determines whether it is necessary to remove the spatial feature from the local geographic code.

The geographical code conversion unit 530 generates and maintains a geographical code used in the local space.

The receiver 540 converts the radio signal of the transmit / receive antenna 560 into digital data that can be processed by the data processor 500.

The transmitter 550 converts the digital data output from the data processor 500 into a radio signal and outputs the radio signal to the transmit / receive antenna 560.

The transmit / receive antenna 560 receives and transmits a radio signal.

On the other hand, the geographic code (GGC) used by the location node is expressed including the geographical coordinates of the longitude, altitude, latitude and information on the communication range of the location node.

These geographic codes are constructed through range factors and address codes. Range factors can be expressed in various ways using scales for each axis.

In this case, the address code represents coordinates of the location node and is divided into a relative address code and a fixed address code. Fixed address codes represent coordinates directly in geographic space and relative address codes represent position coordinates relative to any address code.

An example of an expression rule for such a geographic code is as follows.

Code: = {'(' Abs ',' Unit ',' Scale ')'} '(' Real ',' Real ',' Real ')' AbsAddress || '(' Rel ',' Unit ',' Scale ')' '(' Real ',' Real ',' Real ')' RelAdress

In Equation 1, the geographical code (GGC) can be expressed in three forms, and it has two fixed address codes and a relative address code. {} Can be present or not. The absence of {} indicates a fixed address code, where Scale is a single value of 1 and range is m. The scale used here represents a measure of the range concept.

Scale: = Real || '(' Real ',' Real ',' Real ')'

In Equation 2, the scale code Scale is used as a range concept and a length concept.

AbsAddress: = '(' Real ',' Real ',' Real ')' || Alias

In Equation 3, a fixed address code (AbsAddress) may be expressed as a real number for latitude, longitude, and altitude, or may be expressed through Alias.

RelAdress: = '(' Abs ',' Scale ')' '(' Real ',' Real ',' Real ')' AbsAddress || '(' Rel ',' Scale ')' '(' Real ',' Real ',' Real ')' RelAdress || Alias

In Equation 4, the relative address code RelAdress is a method of expressing an address recursively, which is an address code representing an address address of a desired location based on a known address, that is, a fixed address code or a relative address code. Here, Scale represents a measure of the length concept. Relative address codes can also be expressed through Alias. Alias can be used by maintaining on a location server. The location server maintains mapping information for Alias and fixed address codes and relative address codes.

Alias means a string. A string consists of numbers or letters, and the first letter begins with a letter. Alias may express the location information so that the user can easily recognize the location information by naming the geographical location.

At this time, if Abs is 1, a fixed address code is shown, and if Rel is 2, a relative address code is shown. Real indicates that it contains a real number and an integer. Units represent the units of the range: 1 for kilometers (km), 2 for meters (m), 3 for centimeters (cm), and 4 for millimeters (mm).

GeoCodeSystem can be configured through the following expression rules.

In addition, this rule can be used globally by registering with a location server, and can be applied by inputting to location nodes in separate environments.

In the GeoCodeSystem, the code system is represented by a SpaceScale and a GeoAddress Code.

The SpaceScale here is not for GeoAddress but scale for Global Address.

Space_Scale: = '(' Real ',' Real ',' Real ')'

In Equation 5, SpaceScale is a scale for the entire address code, and reflects the characteristics of the terrain form for each network, and provides a method for efficiently managing and maintaining the code.

GeoAdress: = '(' Real ',' Real ',' Real ')'

In Equation 6, a geographic address code (GeoAddress) means a physical location indicating latitude, longitude, and altitude.

Next, an example of the expression rule of the LocalGeoCodeSystem is as follows.

LocalGeoCodeSystem): = '(' AngleUnit ',' θ ',' φ ')'

In equation (7), the coordinate system display code is in coordinate system. θ represents the angle between the x-axis of the geographic code (GGC) coordinate system and the x-axis of the LGGC coordinate system, and φ represents the angle between the z-axis and the xy plane.

At this time, if the AngleUnit is 1, it represents a degree, and if 2, it represents a radian.

An example of applying the above-described expression rule is as follows.

If the geolocation code of the location aware node is (10,20,30) and the GeoCodeSystem is (1,5,1) (5,5,30), then the static address code is 1, (20-5) / 5, (30-30) / 1) = (5,3,0). And if the range scale is (1,2,3) (2,2,2), then the geographic code (GGC) is (1, 1, (1,2,3)) (2,2,2) (5,3, 0). At this time, location-aware nodes within the range of this location-aware node use the same geographical code.

And, in order to give spatial characteristics, using the LocalGeoCodeSystem, if (1,30,90), the fixed address code

로 변환된다. 따라서, 지역지리적 코드(LGGC)는 (1,1,(1,2,3))(2,2,2)(2.078,0.866,0)이 된다.

Is converted to. Thus, the geographic code LGGC is (1,1, (1,2,3)) (2,2,2) (2.078,0.866,0).

On the other hand, using the above geographic code (GGC), it is possible to obtain the characteristics of the following range measures. That is, not only a symmetric space but also an asymmetric space can be represented.

Geographic codes that have these characteristics can be used by the code itself. In addition, in order to efficiently manage and use code, a geocode system (GeoCodeSystem) and a local geocode system (LocalGeoCodeSystem) may be applied.

Using a GeoCodeSystem, a geographic code can be represented through a standardized coordinate system or a relative code system using an origin of the coordinate system as an arbitrary point. In addition, a geocode system may be used to generate a geographic code by converting a geographic address code into an absolute address code, and consider a geographical feature.

Using the LocalGeoCodeSystem, a local geocode can be generated from a geographic code using a local coordinate system. Regional geographic codes have the same rules for representation of geographic codes, but their meanings are different.

The geographic code (GGC) coordinate system and the geographic code (LGGC) coordinate system are described as follows.

The geographic code (GGC) coordinate system uses a standardized coordinate system, and the geographic code (LGGC) coordinate system is based on the geographic code (GGC) coordinate system and constitutes an arbitrary coordinate system in consideration of the local environment. , with φ. θ means the angle between the x-axis of the geographic code (GGC) coordinate system and the x-axis of the LGGC coordinate system and φ means the angle of the z-axis and the xy plane. So θ and z have values from 0 to 90 degrees.

The Local Geographic Code (LGGC) is used to impart spatial characteristics in the local (non-global) environment. In order to give spatial characteristics, we use LocalGeoCodeSystem and generate Local Geographic Code (LGGC).

The LocalGeoCodeSystem can be implemented through a network management system and a location server or by assigning to location nodes individually.

Meanwhile, an example of a process of converting between a geo-address code and a fixed address code using a GeoCodeSystem is as follows.

First, if the geographic address code is (50,60,10) and the geocode system is (4,2,1) (30,40,10), then the static address code of this location is ((50-30) ) / 4, (60 -40) / 2, (10-10) / 1) = (5,10,0). In this case, the scale of the space with respect to each axis is (4, 2, 1), indicating that the spatial characteristics are long in the x-axis direction, and that the reference point of the coordinate system is (30, 40, 10).

Next, if the static address code is (10,4,0) and the geocode system is (2,6,1) (10, -60,10), the geographical address code is (10 + 10 * 2, 4 * 6-60, 1 * 0 + 10) = (30, -36,10).

6 is a flowchart of the present invention.

First, a geographical address code represented by a longitude, an altitude, and a latitude corresponding to an arbitrary position is converted into a geographical code represented by a coordinate and a predetermined range corresponding to the geographical address code (step 600).

Next, it is determined whether spatial characterization corresponding to the geographical code is necessary (step 610). Preferably, the process of determining whether the spatial characterization is necessary (operation 610) is that if the space including the coordinates of the process (step 600) is a local space of less than a predetermined size, it is necessary to impart spatial characteristics corresponding to the local space. It is a process of judgment. Preferably, in the process of determining whether the spatial characterization is necessary (operation 610), if the space including the coordinates of the operation (operation 600) is a global space of a predetermined size or more, the spatial characterization corresponding to the local space is not required. The process is judged to be. Preferably, it is a process of determining whether the location information used in the specific region in the process of determining whether the spatial feature is necessary is a regional geographical code or a regional code or a geographical code that gives the spatial characteristic. Determination of local and global space can be confirmed through the destination address of location-based service data.

Finally, if spatial characterization is required, the geographical code is converted into a regional geographic code including the spatial characteristic (step 620).

FIG. 7A is a detailed flowchart of a process (operation 600) of converting to the geographical code of FIG. 6.

First, it is determined whether a relative address code is necessary (step 701). Preferably, information on whether a relative address code is required may be set in advance.

In this case, if it is determined that a relative address code is required, a reference address code indicating a position different from the origin is generated as a reference for representing coordinates (step 702). In addition, a length scale code representing a distance between the coordinates and the other positions above is generated (step 703). In operation 704, a relative address code is generated using the reference address code and the length measure code.

In contrast, if it is determined that the relative address code is not necessary, the geographical address code is converted into a fixed address code (step 705). In addition, the geographic code is generated by including the range measure in the address code generated in this process (705).

FIG. 7B is a detailed flowchart of a process of converting to a geographical geographic code of FIG. 6 (operation 620).

First, a coordinate system corresponding to a spatial characteristic is generated (step 721). At this time, the coordinate system is a coordinate system transformed at an angle of θ and φ as described above.

Next, convert the geographic code to a regional geographic code using the angle (θ) between the x-axis of the generated coordinate system and the x-axis of the geographic code, and the angle (φ) between the xy plane of the generated coordinate system and the z-axis of the geographic code. (Step 722).

8 is a flowchart according to an embodiment of the present invention.

The embodiment of FIG. 8 relates to a process of converting a regional geographic code into a geographic code.

First, for a space including any location, it is determined whether spatial feature removal is needed from a local geographic code corresponding to the above location and including the spatial property of the space (step 810). Preferably, the process of determining whether the spatial feature removal is necessary (step 810) is a process of determining that the spatial feature removal corresponding to the local space is not necessary if the space including the location is less than a predetermined size. Can be. Preferably, the process of determining whether the spatial feature removal is necessary (operation 610) may be a process of determining that the spatial feature removal corresponding to the local space is necessary if the space including the above position is a wide space of a predetermined size or more. .

The determination of the global space and the local space can be determined through the destination address to which the location-based service data is delivered. For example, if the regional geographic code is the destination address of the used local space, it is not changed.

Next, if the spatial feature needs to be removed, the local geographic code is converted into a geographic code represented by a coordinate and a predetermined range corresponding to the above location (step 820). Preferably, this process (step 820) is an angle between the x-axis of the coordinate system for the geographical geographic code and the x-axis of the geographical code, the angle between the xy plane of the coordinate system for the geographical geographic code and the z-axis of the geographical code. It may be a process of converting a regional geographic code into a geographic code using.

In the preceding code, the first 1 is a fixed address code system, and (2,2,1) (10,10,1) is a measure of length, and the position of node B is about 2 axes from node A (2 * 10). , 2 * 10,1 * 1).

Also, the relative address code of node C for node B is (1, (3,2,1)) (10,10,1) (30,20,10), and the relative address code for A is (2, (3,2,1)) (10, 10, 1) (1, (2, 2, 1)) (10, 10, 1) (30, 20, 10).
