The guide information may be displayed separately or together with the arrival information of the existing public transportation.

5 illustrates an example of displaying guide information on a public display according to an embodiment of the present invention.

5 (a) and 5 (b) illustrate that the guide information of the present invention is additionally displayed on a public display for guiding the arrival of a train at a subway stop. In FIG. 5 (a), a public display of a destination (dogok and bongbong) that the user wants to go for a user who uses the destination guidance system of the present invention (the user whose end 4 digits are 5746 and 3284, respectively). 5 (b) shows a situation in which a user (a user whose end four digits of the number of the portable terminal is 2445) who is using the destination guidance system of the present invention is incorrectly waiting on the opposite platform. Is an example of how to guide you to the correct platform.

Meanwhile, even if the waiting platform is correct, the public display of the opposite platform may be displayed as shown in FIG. 5 (b). The same user may be displayed on the correct platform as shown in FIG. 5 (a) and on the other platform as shown in FIG. 5 (b). In this case, the user may be located on any of the two platforms. Such display may be more effective because it may be difficult to accurately recognize the platform on which the user is located at a stop, such as a subway.

Figure 5 (c) illustrates that the guidance information of the present invention is additionally displayed on the public display to guide the arrival of the bus at the bus stop. The line number of the bus that stops at the bus stop and the estimated time of arrival are displayed, and each user wants to go to the user (customer ID is khlee, jhkim, dkyoo, soony) using the destination guidance system of the present invention. It shows the destination to say. In addition, since the user with cyim is waiting at the wrong stop, the user is guided to use the opposite stop. In addition, the same user may be displayed in the waypoint at the correct bus stop, and at the same time, the wrong user may be displayed at the same time to guide the way to and from the correct stop.

As such, it is possible to provide a personalized destination guidance system by utilizing the existing public display installed so that individual users can board the public transportation to the destination safely and conveniently.

The guide server 100 receives the destination guide request information and / or the location estimation signal information from the portable terminal 400, and estimates the standby stop currently waiting for the portable terminal 400 using the location estimation signal information.

The guide server 100 determines whether the estimated standby stop is located at the correct stop using the destination information included in the destination guide request information and the database 140 included in the guide server 100, and determines the determination. Therefore, different guidance information is generated.

That is, the guide server 100 determines whether the public transportation passing through the estimated standby stop is directed to the destination of the user or the stop adjacent to the user's destination.

If it does not head to the destination, the public transportation to the destination determines the adjacent stops of the waiting stops, and according to the decision, includes indications and user identification information from the current standby stops to the adjacent stops. Generate guide information.

On the other hand, when heading for a destination, guide information is included, which includes destination information and user identification information received from the portable terminal 400, and further includes identification information of a public transportation means.

The guide server 100 then transmits this guide information to one or more public displays 200 of the standby station where it is estimated that the portable terminal 400 is located.

The one or more public displays 200 may be all public displays 200 installed in a standby stop. Alternatively, the one or more public displays 200 may be selected from the guidance server 100, for example determined from a location estimate of the portable terminal 400 in a standby station or to identify the public display 200. It may be one or more public display 200, determined using the identification information of the.

In general, standby stations such as subway stations are provided with a plurality of public displays 200. In addition, some of the plurality of public displays 200 may be shared displays facing in the direction opposite to the direction in which the subway proceeds with the others.

It may also be inaccurate to estimate stops such as subway history or bus stops.

Therefore, the guide server 100 may cause some errors in the estimation of the standby stop for the portable terminal 400 and the estimation of the position in the standby stop. However, in consideration of this error, the portable terminal 400 currently exists. It is possible to transmit the guide information to all public display 200 in a certain area (for example, within 30m, etc.) from the location.

In this case, some of the public transportation means and some of the public transportation means of the one or more public displays 200 receiving the guidance information are directed in the opposite direction or in a different direction, and thus the guidance information transmitted to each public display 200. May be different from the guide information transmitted to the other public display 200.

By transmitting the guide information to the one or more common display 200 in this manner, the user is provided with accurate guidance in consideration of an error in the position estimation of the portable terminal 400.

Therefore, if the location of the stop is not correct, it is necessary to transmit the guide information including indications to other stops (e.g., adjacent stops) other than the currently waiting standby stop, whereas the correct destination includes the user's destination information. Transmits the guide information to confirm that the user is going in the right direction.

More detailed description of the guide server 100 will be described below with reference to FIG. 2.

The communication network 500 connects one or more portable terminals 400, one or more public displays 200, and / or a wireless device 300 to the guide server 100 by wire or wirelessly to transmit and receive data.

 The communication network 500 may be different according to the available communication types of each of the portable terminal 400, the wireless device 300, and the common display 200. In addition, the public display 200 may also be connected to the guide server 100 using a wired or wireless network. Similarly, the wireless device 300 may be connected to the guidance server 100 in a similar manner.

Therefore, the communication network 500 may be connected to the guide server 100, the portable terminal 400, or the common display 200 through a wired, wireless or a combination of wired and wireless networks.

The wireless device 300, which may be further included in the present destination guidance system, is installed at a subway station or a bus stop and transmits identification information of the wireless device 300 through short range wireless communication.

The identification information of the wireless device 300 transmitted in this way may be received by the portable terminal 400, and the identification information of the wireless device 300 may be transmitted to the guide server 100 via the portable terminal 400. have.

The wireless device 300 may be, for example, a wireless access point (AP), a Bluetooth device, a Zigbee device, or the like, which may use short-range wireless communication.

The identification information of the wireless device 300 may identify at least one public display 200 installed at a stop such as a subway station or a bus stop.

For example, one wireless device 300 may be installed adjacent to or embedded in one common display 200. Therefore, in this case, the identification information of the wireless device 300 may directly identify one installed public display 200. Alternatively, for example, one wireless device 300 may be located between a plurality of common displays 200.

The destination guidance system of the present invention as described in FIG. 1 provides the user with accurate, safe and convenient guidance even when the user of the portable terminal 400 visits an unfamiliar province or city or uses a new route. Do it.

2 is a diagram illustrating an exemplary block diagram of the guide server 100.

According to FIG. 2, the guide server 100 may include a volatile memory 110, a nonvolatile memory 120, a hard disk 130, a database 140, and a communication network interface unit connected to a system bus and / or a control bus. 150 and control processor 160. Some of the blocks may be omitted according to the implementation example, or blocks not included in FIG. 2 may be further included in the block diagram constituting the guide server 100.

In this case, the guide server 100 does not need to be configured as a single device, but may be divided into a plurality of functionally divided servers. For example, the information server 100 is divided into two servers, and one server is a location server capable of estimating the location of the mobile terminal 400 in real time. It may be divided into a destination guide server 100 that estimates a standby stop from the estimated position and transmits guide information to one or more public displays 200 of the estimated standby stop.

Looking at each of the blocks constituting the guide server 100, the volatile memory 110 is a memory, such as a DRAM (RAM) type of the stored data is destroyed as the power supply is interrupted. The volatile memory 110 temporarily stores various data or programs stored in the nonvolatile memory 120 and / or the hard disk 130, and is more than the access speed of the nonvolatile memory 120 or the hard disk 130. At a high speed, the control processor 160 allows access to data or programs.

The nonvolatile memory 120 may be a NOR type or NAND type memory in which stored data is maintained even when power supply is interrupted. In the nonvolatile memory 120, a booting program necessary for booting the guide server 100 may be stored, and various setting data that may be set on the guide server 100 may be stored.

The hard disk 130 includes a variety of programs and data necessary for operation of the guide server 100 as a large-capacity storage medium. For example, the identification information of the user who uses the portable terminal 400 or the portable type used by the user. Identification information of the terminal 400 may be stored in advance or received from the user's portable terminal 400 and stored.

In addition, the hard disk 130 may further include a database 140 program for managing the database 140 or creating and deleting a record. The hard disk 130 may further include a route determination program for receiving destination guidance request information from the portable terminal 400 and determining a public transportation route based on the destination information included in the received destination guidance request information, and a portable terminal ( Receiving location estimation signal information periodically or aperiodically from 400 and estimating the location of the mobile terminal 400 from the received location estimation signal information and an atmospheric stop from the location, and one or more public displays associated with the estimated atmospheric stop. It includes a guide program for transmitting the generated guide information.

These programs can be implemented in various forms using processes or threads. These programs may be loaded and run in the control processor 160.

The database 140 systematically stores and manages data necessary for guiding a user of the portable terminal 400 to a destination. Although the database 140 is illustrated as a separate block in FIG. 2, this is for understanding, for example, the database 140 using the hard disk 130, the nonvolatile memory 120, and the volatile memory 110. ) Can be stored, and the control processor 160 can be used to modify the record or add a new record. Alternatively, the database 140 is not limited to the case of using a database program known in the art and includes a program and a data structure configured using a general data structure.

Here, the database 140 includes a public transportation DB 141, a stop-public display association DB 143, and a public display location DB 145.

Looking at the DB included in the database 140 in more detail, the public transport DB 141 includes route information for a plurality of public transportation means.

Such public transportation means include, for example, subways, buses, trains, etc., and the route information for each public transportation means identification information for each public transportation means (e.g., a line number), identification information of stops that stop. It may include information on coordinates (locations) at which each stop is located, information about a start stop and a destination stop, information on dispatch intervals, and time of arrival at each stop.

Here, the coordinate information where each stop is located does not necessarily need to represent a point in two dimensions, but may be represented as one spatial region (for example, a circular spatial region or a rectangular spatial region). Such coordinate information may be mapped to a specific map of a city or province. The route information for the plurality of public transportations may be configured in the form of a layered recorder.

The station-public display association DB 143 represents the mapping relationship between the station and the public display 200. This station-public display association DB 143 provides a number of information needed for each of a plurality of stations, for example, a record for each station may include an identification information field for identifying a station and one or more public displays 200. ) And a direction field to identify the direction of each public display 200 (e.g., to identify one direction and vice versa of a public transport departing from a station or a plurality of directions). Subordinate coordinate information (to identify directions) and route information of public transportation, in addition to coordinate information (or spatial area information) of the station or subordinate coordinate information corresponding to each direction field and belonging to the coordinate information (spatial area information) of the station. Or sub-space area information).

The record for each stop further includes identification information of a device such as a wireless device 300 or a base station installed in the stop, and sub-coordinate information (or subspace area information) of the identification information of each device. can do.

Each station may consist of a plurality of records in the case of a plurality of public displays 200, and each record may be divided into two classes according to the direction field of the record. For example, a single stop may be represented by a plurality of records, but a single record may be configured in a structured or hierarchical form by including the information described above as a single record.

On the other hand, the identification information for identifying a station in the station-public display association DB 143 is not necessarily the same as the station recognized by the user of the portable terminal 400.

For example, if a user of the portable terminal 400 has two subway lines separated from one stop (for example, A subway station), the stop having a separate subway line for the two subway lines may be a stop- In the public display association DB (143) may be separated into two station identification information. Of course, in the case of using one piece of identification information, the sub-stop identification information may be further added and distinguished.

The public display location DB 145 allows each public display 200 to be identified in a plurality of public displays 200 that the guide server 100 can use.

The public display location DB 145 is a public display 200 identification information for one common display 200, identification information of the wireless device 300 adjacent to or embedded in the public display 200 and the public display. It may further include identification information of the station where the 200 is installed or coordinate information (or area information) of the common display 200.

The identification information of the wireless device 300 included in the common display location DB 145 may be identified in the same form as the identification information of the wireless device 300 that may be included in the location estimation signal information received from the portable terminal 400. Information.

The public display identification information included in the public display location DB 145 may further include address information for accessing the public display 200 through the communication network 500 as this identification information or separately. Therefore, the identification information of the received wireless device 300 may be used to easily determine location (coordinate) information on which the portable terminal 400 is located or to easily determine a corresponding common display.

In addition, the database 140 may further include a map DB. Such a map DB can identify a building, a road, an address, etc., and can identify a building, a road, an address, etc. in a specific coordinate.

By using the database 140, the position estimation signal information received from the portable terminal 400 and the coordinate information of the stop or the common display 200 can be used to guide the user who wants to go to the destination using the portable terminal 400. To be accurate and convenient.

The communication network interface unit 150 receives location estimation signal information connected to the communication network 500 to estimate the position of each of the one or more portable terminals 400, and uses the database 140 to control the control processor ( The guide information generated by the 160 is transmitted to the common display 200. Here, the position estimation signal information may include identification information of the wireless device 300. The network interface unit 150 may be configured to accommodate one or more communication protocols.

The control processor 160 controls each block of the guide server 100, and preferably controls each block using a program stored in the nonvolatile memory 120 or the hard disk 130, for example, a plurality of blocks. It may include the processor core (core) of.

The control processor 160 receives the destination guide request information from the portable terminal 400, and the destination guide request information further includes destination information and user identification information for the user's destination.

From the destination information, the public transport route to the user's destination is determined using the map DB and the public transportation DB 141 included in the database 140. Here, the public transport route may include the case of using a plurality of public transportation means, and may include one or more transit stops.

When the user is located at the transfer stop, the control processor 160 may control to provide the guide information at the transfer stop.

In addition, the control processor 160 estimates the standby station where the portable terminal 400 is located by using the station-public display association DB 143 from the position estimation signal information received from the portable terminal 400.

Alternatively, the control processor 160 identifies the common display 200 using the common display position DB 145 from the identification information of the wireless device 300 included in the position estimation signal information received from the portable terminal 400. In addition, the station-public display association DB 143 may be used to estimate the standby station where the portable terminal 400 is located.

The control processor 160 then determines whether the public transportation stop at the estimated standby stop using the stop-public display association DB 143 is directed to (or passes by) the user's destination and is different according to this determination. Generate guide information.

The control processor 160 may access the communication network 500 with guide information for at least one public display 200 selected from the one or more public displays 200 mapped to the estimated standby stop. This guide information can be transmitted using the address information of.

The public display 200 selected here is not necessarily the public display 200 in the same direction. Therefore, in consideration of the error of the estimated position (coordinate) information of the portable terminal 400, the common display 200 in a predetermined area (for example, circular) of the standby stop estimated from the position information of the portable terminal 400 Can be.

In this case, since the direction fields of each common display 200 may be different, the guide information to the common display 200 having different direction fields may be different.

If it is determined that the control processor 160 is headed for the destination, the guide information includes destination information and user identification information received from the portable terminal 400. On the other hand, if it is determined that the vehicle is not headed for a destination, the guidance information includes a map DB and / or a station-public display association DB 143 and the like to identify an adjacent stop and receive a stop toward the received destination. The user identification information is included together with the guide display of the station (for example, the arrow or the character display of the direction information together with the identification information of the adjacent station).

The execution flow performed in the processor 460 will be described in detail later with reference to FIG. 3.

3 is a flowchart illustrating a destination guiding method using a common display of the present invention stop executed in the guiding server 100.

3 may be performed in the form of an application program by the control processor 160 of the guide server 100.

Referring to the flowchart of the destination guidance method using the common display of the stop of FIG. 3, the flowchart of FIG. 3 may be started by receiving destination guidance request information from the portable terminal 400 (S100).

The user of the portable terminal 400 for using the destination guidance method of FIG. 3 may preferably register as a user in the guide server 100 using an application program mounted in the portable terminal 400 in advance. You can log in to receive user authentication.

First, in step S110, the guide server 100 receives the destination guide request information including the destination information from the portable terminal 400.

The destination guide request information includes destination information indicating a destination that a user of the portable terminal 400 wants to visit using public transportation such as a subway or a bus.

In addition, the destination guide request information may further include identification information such as user identification information of the portable terminal 400, identification information of the portable terminal 400, or a line number of a public transportation means to be used for a destination.

Of course, the identification information of the user or the identification information of the portable terminal 400 may be replaced with the identification information stored in the guide server 100, in which case the identification information may be omitted.

In step S120, the guide server 100 determines the public transport route to the destination using destination information included in the destination guide request information.

Here, in step S120, the identification information of the currently located stop received from the portable terminal 400 is determined as the start point of the public transportation route search, or in step S120 further receives the position estimation signal information from the portable terminal 400 An atmospheric stop estimated from the position estimation signal information is determined as a starting point.

Then, the public transportation route from the starting point to the destination included in the destination information is determined using the map DB of the guide server 100 and the public transportation DB 141. Since such a determination method is obvious to those skilled in the art and can be easily implemented, a detailed description thereof will be omitted.

The public transportation route thus determined may utilize a number of public transportations, and thus include one or more transit stops for transferring multiple public transportations.

Such transit routes include a starting stop, in addition to one or more transit stops, a destination stop close to the destination or destination, and include the line number of the public transportation to be boarded at the starting and transit stops, in addition to the direction in which each stop is different. (I.e., a bi-directional stop), further includes direction information at each stop (for example, the next stop or final stop of public transportation, or the direction field of the stop-public display association DB 143).

The determined public transportation route may be transmitted to the portable terminal 400 in the form of a sentence and / or in the form of displaying the public transportation route on a map.

In step S130, the guide server 100 receives the position estimation signal information periodically or aperiodically from the portable terminal 400. The received position estimation signal information may be a signal received only when a user of the portable terminal 400 is located at a stop and waits.

Therefore, the user of the portable terminal 400 automatically (for example, recognizes that the portable terminal 400 gets on or off the public transportation by using RFID or the like) when the public transportation is in use or the portable terminal 400. By setting the user's input through the output unit and the input unit of the guide server 100 can be informed.

The position estimation signal information received in step S130 includes GPS coordinate information generated using a GPS receiver of the portable terminal 400, identification information of the wireless device 300 received through short-range wireless communication, and / or a mobile telephone network. It may include identification information of the base station through which the mobile terminal 400 can communicate.

Such identification information included in the position estimation signal information may be used to estimate the position of the portable terminal 400 and to estimate the location or adjacent standby stop of the portable terminal 400.

In addition, the position estimation signal information may further include a signal strength of a radio signal corresponding to each identification information (for example, a radio signal transmitted from the base station or the wireless device 300), and the signal strength of the radio signal may also be located. Can be used for estimation.

In step S140, the guide server 100 estimates the position of the portable terminal 400 from the position estimation signal information and estimates the standby stop from the estimated position (coordinate).

Here, the standby stop does not need to be a stop of the starting point where the user first rides, but may be a transfer stop on a public transportation route.

If the presumed standby stop is not a transit stop on the public transport route or a stop on the public transport route, it is again possible to determine the public transport route back to the destination in step S140 and change the public transport route accordingly and change the public transport. The route may be transmitted to the portable terminal 400.

In operation S140, the method of estimating the standby stop may vary according to the type of identification information included in the location estimation signal information. This will be described in more detail with reference to FIG. 4.

In step S150, the guide server 100 determines whether the public means of transportation at the estimated waiting stop to the destination. This determination may be determined from the public transportation route determined in step S120.

That is, if the estimated waiting stop is the same as the starting stop or transit stop on the public transport route (or a specific stop on the public transport route), then you are on the public transport route to the destination and you are at the correct stop to the destination. It can be judged that.

If the judgment at the estimated standby stop does not lead to the destination, check whether one or more stops adjacent to the estimated standby stop (within a certain distance) are already on the determined public transport route and, if so, the adjacent The guide server 100 may determine to guide the stop.

However, if it is not a determined stop on the public transport route, the guidance server 100 further determines a public transport route to a destination starting at one or more adjacent stops again, and among the plurality of public transport routes, the shortest, minimum distance, and the like. According to the same criteria, one adjacent stop can be determined and guided to this adjacent stop.

Meanwhile, the station-public display association DB 143 may include a direction field in a record corresponding to the estimated standby station. Therefore, a standby stop with a direction field should further consider the direction field to determine if it is headed to its destination. This determination may be based on the position (coordinate) of the portable terminal 400 estimated in step S140 and utilizes the sub-coordinate information (sub-space area information) corresponding to the direction field of the atmospheric stop. It may be determined whether it belongs to the sub coordinate information.

Therefore, the determination at the standby stop having the direction field may vary according to the position of the portable terminal 400. In addition, the determination at the standby stop having the direction field may be subdivided into the determination of at least one public display 200 installed at the standby stop. For example, the determination of the common display 200 installed at a position facing in a specific direction may be different from the determination of the common display 200 facing in the opposite (or different) direction. For example, the determination on the common display 200 installed at a position facing in a specific direction may be determined to be directed to the destination, and the determination on the public display 200 facing in the opposite (or other) direction is not directed to the destination. You can judge.

With such a refined judgment, the user of the portable terminal 400 can easily and conveniently go to a desired destination easily and conveniently and safely at a stop facing in various directions.

In step S160, the guide server 100 transmits to the one or more public displays 200 associated with the standby stop, the guide information to know whether the public means of transportation at the location where the one or more public displays 200 is installed to the destination. do.

To this end, the guidance server 100 identifies all public displays 200 included in the standby station using the station-public display association DB 143 and selects or estimates all of the identified public displays 200. Select the common display 200 installed at a position adjacent to the position (coordinate) of the portable terminal 400 (for example, within 30 m), or the common display 200 corresponding to the identification information of the wireless device 300. ) (In addition to the common display 200 adjacent to the public display 200) is selected to transmit the guide information to the selected public display 200.

Such guidance information may also be further transmitted to the portable terminal.

On the other hand, the guide information may be different according to the determination in step S150. If the determination in S150 determines that the standby stop is for the destination, the guide information may include destination information indicating a destination to which the user wants to go, and may further include user identification information or identification information of the portable terminal 400. have. In addition, the guide information may further include a line number of the public transportation to be used by the user when a plurality of public transportation stops at the standby stop.

If the determination in S150 determines that the standby stop does not go to the destination, the guide information includes information for guiding to the adjacent stops determined in step S150. Such guide information may include user identification information or identification information of the portable terminal 400, identification information of adjacent stops, text or map information for guiding directions and directions to the adjacent stops. Or in addition, it may further include destination information. The subway stop may display different information as described above depending on the platform.

By transmitting such guidance information to the public display 200, the user can easily know what other stops should be used when not passing by public transportation means to the destination they want to go.

Of course, one or more of the public display 200 (in the case of selecting the public display 200 adjacent to all or the position (coordinate) of the portable terminal 400) selected in S160, as can be seen in step S150 If includes a direction field, different guide information may be received and displayed.

Even if different guide information is displayed at the same time, this corresponds to the case where each common display 200 faces in a different direction, and considering the error of the estimation of the position of the portable terminal 400, This allows for easy error guidance while allowing for errors without the need for positioning.

4 is a diagram illustrating a detailed flowchart of estimating a standby stop according to the type of identification information included in the position estimation signal information for step S140.

In FIG. 3, the process starts with step S140 (step S141) and ends with completion (step S148), and returns to the flowchart of FIG. 3.

First, in step S142, it is determined whether the position estimation signal information includes identification information of the wireless device 300.

This determination is made by receiving the identification information of the wireless device 300 included in the common display location DB 145 or the identification information of the wireless device 300 included in the station-public display association DB 143. ) Can be determined by comparison with the identification information or by using the type field of the identification information that can be included in the position estimation signal information.

If it is the identification information of the wireless device 300, the flow advances to step S143 to identify one or more public displays 200 corresponding to the identification information of the wireless device 300 in step S143. In the present embodiment, it is assumed that the wireless device 300 is installed on or adjacent to a specific public display 200.

To this end, the public display 200 is determined from the received identification information of the wireless device 300 by determining whether the corresponding public display 200 is in the public display position DB 145 and determining the identification information of the corresponding public display 200. 200 can be identified.

If there is no identification information of the wireless device 300 received in the public display location DB 145, the identification information of the wireless device 300 included in the station-public display association DB 143 may be utilized, and accordingly, In addition, the bus stop including the identification information of the wireless device 300 may identify one or more public displays 200 belonging to the sub-coordinate information (or sub-space area information) of the wireless device 300 or within a predetermined distance. .

The standby station corresponding to the common display 200 identified in step S144 is estimated using the station-public display association DB 143.

To this end, the record to which the identification information of the identified public display 200 belongs is determined in the stop-public display association DB 143, and the stop of the determined record may be estimated as the standby stop.

Meanwhile, as another embodiment, the wireless device 300 may also have a method of estimating a standby stop when the wireless device 300 is installed regardless of the common display 200 (not shown). The database 140 may further include information on the installation location of the wireless device 300, and the installation location information of the wireless device 300 may include identification information of an installed stop and / or a location where the wireless device 300 is installed. Coordinate information and the like. The location of the portable terminal 400 or the station where the portable terminal 400 is located may be immediately identified using the identification information and / or signal strength of the wireless device 300 included in the received position estimation signal information. .

On the other hand, if it is not the identification information of the wireless device 300, it is determined in step S145 whether the position estimation signal information includes GPS coordinate information.

In the case of including the GPS coordinate information, in step S146, the corresponding atmospheric stop is estimated from the GPS coordinate information.

To this end, by comparing the coordinate information (or spatial area information) of the station included in each record of the station-public display association DB 143 with the coordinate information of the GPS, it is possible to estimate the standby station within a certain distance or within.

If it does not include GPS coordinate information, it is information other than the identification information or GPS coordinate information of the wireless device 300 described above. Such information may include, for example, identification information of the base station. The identification information of the base station may be used to compare identification information of a device such as a base station included in the station-public display association DB 143, and to estimate a stop of a matching or adjacent record as a standby station.

Here, the at least one public display 200 selected in step S160 may be configured differently according to the type of identification information included in the position estimation signal information.

For example, in the case of identification information of the wireless device 300 included in the public display location DB 145, only the identified public display 200 or the public display 200 within a predetermined distance to the identified public display 200. ) May be selected.

Alternatively, when using GPS coordinate information, the common display 200 may be selected within a predetermined distance (for example, 10m) in consideration of the error of the GPS coordinates.

On the other hand, when using a base station with strong signal strength, all the common displays 200 of the station to which the base station belongs may be selected.

As described above, the common display 200 different from each type of identification information is selected to transmit the guide information, so that the error of the position estimation of the portable terminal 400 can be taken into account from each identification information.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings.
