Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses short-range wireless communication between a plurality of base stations located in various places and a mobile terminal device to reach a destination of a user of the mobile terminal device. The present invention relates to a destination arrival guidance system, a base station, and a mobile terminal device that guide the user.

[0002]

2. Description of the Related Art In recent years, mobile terminal devices represented by mobile phones (hereinafter, also simply referred to as mobile terminals or terminals) have been rapidly spread. As one usage form of this mobile terminal, the fact that each telephone base station has a unique area (cell) in which it can communicate with the mobile terminal is used. The position can be recognized. Japanese Unexamined Patent Publication No. 9-271075 discloses a technique of using such a function to inform a user that he / she has arrived at a target station when getting on a vehicle such as a train or a bus.

[0003]

However, in this prior art, since the position is judged on the basis of the cell, it is considered that the error of the detected position is large. In particular, when the destination is an arbitrary building or facility rather than a vehicle station, the problem of error becomes more noticeable, which may hinder practical use. In addition, it may not be used in places where the radio waves of the telephone base station do not enter, such as underground. Furthermore, in the above-mentioned conventional technique, only the arrival at the destination is notified, and guidance is not provided in the middle of reaching the destination.

The present invention has been made in such a background, and an object thereof is a destination arrival guide system having a relatively small position error and capable of being used even in a place where radio waves of a telephone base station do not enter. , To provide a base station and a mobile terminal device.

Another object of the present invention is to provide a destination arrival guidance system, a base station and a portable terminal device which can provide guidance at an intermediate stage until reaching the destination.

[0006]

A destination arrival guidance system according to the present invention stores a plurality of base stations each storing current location information and communicating with a mobile terminal device existing in the vicinity by a short-range wireless communication function. The mobile terminal device includes a mobile terminal device that communicates with a base station by a short-range wireless communication function, the mobile terminal device acquires destination information according to a user's instruction, and enters a communication area of any of the plurality of base stations. When communicating with the base station, the distance information from the current position to the destination obtained based on the destination information and the current position information of the base station is acquired, and the destination is given to the user based on the distance information. It is characterized by notifying the degree of reaching.

The destination may be anywhere as long as there is a base station for short-range wireless communication, and the user holds the destination information in his / her own portable terminal device and is moving toward the destination. Each time the vehicle passes near the base station at a place other than the destination, the distance from the current position to the destination is obtained and the degree of arrival at the destination is notified.
This notification information functions to help the user to reach the destination.

As for the distance information, the base station transmits the current location information to the portable terminal device, the portable terminal device calculates the distance information to the destination, and the portable terminal device transmits the destination information to the base station. In some cases, the base station calculates the distance information to the destination and transmits the distance information to the mobile terminal device.

Each base station stores the map information of its surroundings and transmits the map information to the mobile terminal device of the communication partner, and the mobile terminal device displays the map information on its own display section. You may do it. In this case, the map information around the base station is sequentially obtained on the route on the way to the destination.

The mobile terminal device can identify and display the present location of the base station when the map information is displayed. When the destination is included in the range of the map information, the mobile terminal device can display the map information when the map information is displayed. It is also possible to identify and display the destination. Further, when the destination is not included in the range of the map information, the mobile terminal device may display the direction of the destination at the time of displaying the map information by identifying the direction of the destination. The direction of the station may be identified and displayed. These display contents function as better guide information for the user.

The mobile terminal device may discard the last received map information at the time of or before receiving the map information from the base station. As a result, the storage capacity of the memory for the unnecessary map information is saved.

[0012] Each base station stores guide information different from the map information of its surroundings, and when the destination and the current location match, the guide information is replaced with or added to the map information. May be transmitted to the mobile terminal device.

When the portable terminal device has an internet connection function, the portable terminal device can acquire the destination information from a web site on the internet.

It is a part that wirelessly connects with 0. In addition, although not shown, an operation unit and a display unit may be provided.

FIG. 4 shows an operation image of destination arrival guidance using the BT base station. The user of the mobile terminal 20
The destination information is acquired from the WEB server 11 or the like. The user has never visited this destination and knows its approximate location but not the exact location. In such a case, the user captures the destination information in the mobile terminal 20, and thereafter, automatically or in response to an operation instruction from the user, an operation mode in which arrival and arrival at the destination are monitored and guided (destination monitoring mode). Say). Here, the point C is set as the destination, and the case where the points A and B are passed on the way to the point C is shown. A base station is located at each point. On the way to the point C, the user carrying the portable terminal 20 enters the communication area near the base station 30a at the point A. The range of this communication area is, for example, a range of about 10 m to several 10 m in radius,
The shorter this distance is, the more accurately the arrival at the destination can be notified, but the lower the detection sensitivity of the base station by the mobile terminal. The mobile terminal 20 that has entered the communication area of the base station communicates with this base station and acquires the position information (current position information) of this base station 30a. The mobile terminal 20 compares the present location information with the destination information stored therein and recognizes that the destination has not been reached yet. When the user further moves in the approximate direction of the destination, the user passes through the communication area of another base station 30b at the point B. At this time, the mobile terminal 20 acquires the current location information and recognizes that the destination has not been reached, as in the case of the point A. When the user enters the communication area of the base station 30c at the point C, which is the destination, the mobile terminal 20 recognizes that the destination is reached based on the current location information acquired from the base station, and notifies that fact. The user is notified in a predetermined form.

Various services are conceivable for the destination information to be acquired by the WEB server, but the method of determining the destination is roughly classified into the following two cases.

(1) In the case where a user directly designates a specific destination intended by the user The specific destination is, for example, various facilities such as a movie theater, a theater, a concert venue, a school, a hotel, a building, a restaurant. And so on. As a method of specifying a specific destination,
Point input on the map, selection input from the menu, etc. can be considered.

(2) When the destination is determined as a result of the search of information other than the destination In this case, an arbitrary search, for example, input by selecting the search result such as restaurants by genre can be considered.

The position information in this embodiment is assumed to be latitude and longitude information. The position information is not limited to the latitude and the longitude, but as described later, it is desirable that the position information be in a format in which the mutual distance between the two positions can be obtained based on the information. This allows any base station to find the difference distance from its current location to the destination. By notifying the user of this distance in a predetermined form, the user can be guided to the destination. The predetermined form includes (1) speaker 2
Generation of sound or voice by 04, (2) Vibrator 2
16 vibration, (3) display on display unit 210, (4)
Any combination of these is possible. "display"
In this aspect, the distance can be displayed numerically or graphically.

The destination monitoring mode may be activated by a user's instruction when reaching the vicinity of the destination. That is, it is not necessary to immediately activate the BT communication circuit unit at the position where the destination information is acquired from the WEB server. For example, when it is known that the nearest station to the destination is Tokyo station, the user activates the destination monitoring mode after arriving at Tokyo station by train. The power consumption of the mobile terminal 20 can be reduced by keeping the operating power supply of the BT communication circuit unit off until this activation.

Further, even after the BT communication circuit section is activated, the operation may be intermittently executed. In this case, the time interval of the intermittent operation may be constant, but if the distance from the current position to the destination is large, the time interval may be lengthened and the time interval may be shortened as the distance to the destination increases. .

FIG. 5 shows a schematic sequence of communication between the base station and the portable terminal in this embodiment. In the present embodiment, each base station with which the mobile terminal communicates performs processing such as calculation of the distance from its current location to the destination,
FIG. 5A shows a case where the terminal performs the processing.
(B) shows the case where the base station performs the processing.

In FIG. 5A, the BT device (not shown) of the base station periodically carries out inquiry broadcast (41). The inquiry broadcast means that the base station transmits a predetermined radio signal to the surroundings in order to check what kind of BT device exists in the vicinity. In response to this, the terminal returns a predetermined response signal (information such as BT address and clock) (42). Then, predetermined connection authentication is performed (43). This connection authentication is for determining whether the terminal is qualified to use the service provided by the base station. For example, the terminal transmits specific parameters to the base station, Can be done by checking this. Such specific parameters can be stored in the terminal in advance, or can be acquired together with the destination information when acquiring the destination information. If the connection authentication is successful, the communication link between the terminal and the base station is established (44), and the base station transmits the current location information held in advance to the terminal (45). The terminal receives the current location information, compares it with the destination information, and calculates the difference distance. The processing of the terminal based on this difference distance will be described later. After that, this communication link is disconnected (4
6).

In FIG. 5B, the processes up to inquiry broadcast (51), response (52), connection authentication (53), and link establishment (54) are the same as in the case of FIG. 5A. Next, in this example, the terminal transmits the destination information held by itself to the base station (55). The base station compares the received destination information with the current location information held by itself, and calculates the difference distance between them. This distance information is sent to the terminal (5
6) The link is disconnected (57).

FIG. 6 is a flowchart showing an example of the processing of the terminal from the time when the user of the terminal acquires the destination information to the arrival at the destination. In this example, the terminal side calculates the difference distance. However, the basic operation in the present embodiment is the same when it is performed on the base station side.

The terminal acquires the destination information as described above (S11). Then, the destination monitoring operation is started according to the user's operation instruction or the like (S12). At this time,
A flag a described later is reset to 0. After that, when this terminal enters the BT communication area of the base station in the present embodiment (S13, Yes), the current location information is obtained (S14). The present location information and the destination information are compared, and the difference distance between the two is calculated (S15). As described above, when the differential distance is calculated on the base station side, the current position information is transmitted in step S14 and the differential distance information is received in step S15. In a succeeding step S16, it is checked whether or not the flag a is 1 and the current position is 100 m or more from the destination. If the flag a is 0, it is checked whether the difference distance is within 100 m (S18).
If it is 100 m or more, the process returns to step S13. When returning to step S13, if it is within the BT communication area of the same base station, the process stays at step S13.

If it is determined in step S18 that the distance is within 100 m, the flag a is set to 1 (S1
9). That is, the flag a is for holding the information once it enters the range within 100 m from the destination. Then, it is checked whether or not the difference distance is within 50 m (S20). If not, it is determined that the present location is within the range of 50 to 100 m from the destination, and the first approach notification (approach notification 1) is performed (S21). As described above, various notification modes are conceivable. For example, a sound is played once, a predetermined melody is played,
The user is informed of this by operating the vibration for 1 second. At the same time, it may be displayed on the screen by characters, symbols, graphs, or the like. Of course, a voice notification such as "I have reached the destination within XX m" may be sent. The calculated difference distance is embedded in “◯◯”. After step S21, step S13
Return to.

When it is determined that the distance is within 50 m from the destination, it is further checked whether the distance is within 10 m (S22). If not, the current location is determined to be within the range of 10 to 50 m from the destination, and the second approach notification (approach notification 2) is performed (S23). In this case, for example, the notification form distinguished from the approach notification 1 is adopted by changing the number of times the sound is generated or changing the tone color, changing the melody, changing the duration of vibration, or the like. After step S23, the process returns to step S13.

When it is determined that the destination is within 10 m, the user is notified that the destination has been reached in a predetermined notification form. Finally, if there is a base station at the destination, the difference distance will be zero.

In step S16, if the flag a is 1 and it is determined that the destination is 100 m or more, the destination is once approached to 100 m and then set to 1 again.
This corresponds to the case where the distance is more than 00 m. Even in such a case, the fact is notified to the user in a predetermined notification form (S17). This notification form can be distinguished from the other notification forms described above.

The number of stepwise distances (100 m, 50 m, 10 m) to be checked, specific numerical values, and specific notification modes are examples, and the present invention is not limited to these. .

In the above description, the present location information or the differential distance information is given as the information given from the base station to the terminal.
At the same time, other information may be given to the terminal. One example is map information around the base station. This map is of a scale and range that functions as a route guide for the user around the base station. This range does not have to match the coverage area of the base station. A second embodiment of the present invention using such map information will be described with reference to FIGS.

FIG. 7A shows that the present location is 150 m to the destination.
The example of a screen of the terminal which displayed the map information obtained from the base station in the position of is shown. On this screen, the difference distance "150 more
m ”is displayed. This allows the user to know the geography in the vicinity and the distance to the destination. FIG. 7B shows an example of a screen when the user further approaches the destination. On this screen, since the destination information exists within the range of this map, the present location and the destination are displayed in a distinguishable manner. For this identification display, characters such as “current location” and “destination”, symbols such as arrows pointing to them, and an optional method such as highlighting of a building or the like as the destination can be adopted. FIG. 7C shows an example of a screen when the terminal is within the communication range of the destination base station. In this example, it can be seen that the destination has arrived because the current location and the destination overlap.

As yet another example, the information provided by the base station may be changed when the destination arrives and when it does not arrive. For example, detailed information of the destination may be prepared separately from the surrounding map information. As the detailed information, for example, when the destination is a building, guidance information up to the target floor of the building, or when the target floor is wide, map information of the floor can be included. In the example of FIG. 7C, the character “arrival!” Indicating the arrival is simply displayed.
Of course, as described above, the sound, voice, vibration, etc. may be used in combination with the notification form.

FIG. 8 is a flow chart showing an example of the processing of the terminal in the second embodiment.

The terminal acquires the destination information as described above (S31), and then, according to the user's operation instruction, etc.
The destination monitoring operation is started (S32). After that, when this terminal enters the BT communication area of any base station in the present embodiment (S33, Yes), its current location information and map information are obtained (S34). At this time, in order to reduce the storage capacity required for the RAM 208 in the terminal, the previously acquired map information may be discarded (overwritten or deleted). The present location information and the destination information are compared with each other, and the difference distance between the two is obtained (S35). As described above, when calculating the difference distance on the base station side, the current position information is transmitted in step S34, and the difference distance information and the map information are received in step S35.

When it is determined that the current location is not within 10 m from the destination (S36, No), the map information as shown in FIGS. 7A and 7B is displayed and the difference distance is displayed or notified ( S38). Then, step S33
Return to. After that, the process stays in step S33 until it enters the BT communication area of the new base station.

10 m from the destination in step S36
If it is determined that it is within the range, the map information as shown in FIG. 7C is displayed and the arrival is notified (S3).
7).

The map display embodiment may be used in combination with the stepwise difference distance determination and notification as shown in FIG.

FIG. 9 shows an example of a screen showing a modification of the second embodiment. FIG. 9A shows the direction of the destination on the map-displayed screen. In this example, an arrow 65 pointing out of the screen is displayed on the road as a direction identifier. This direction is known from the relationship between the present location and the destination. The position of the arrow on the map can be shown regardless of the road, but in the present embodiment, it is on the road closest to the direction from the current position. Since the map information stored in each base station is known in advance, it is possible to classify the directions centering on the current location into, for example, eight directions and set the positions of the arrows corresponding to the respective directions in advance.

FIG. 9B shows the direction in which the user has come to the present location. In this example, the arrow 67 points inward on the screen. This direction can be determined by holding the current position information obtained at the previous base station and comparing it with the current position information of the current base station. The arrangement position of the arrow 67 can be determined by the same method as the arrow 65.

FIG. 10 shows a processing flow of the terminal according to the third embodiment of the present invention. This embodiment is a GP
The S function is used together. That is, the GPS function is used until the destination is approached to some extent, and then B is approached.
Use the T function. GPS cannot be used in a specific building or underground mall because it needs to receive radio waves from satellites. In addition, it is not possible to give individual information to the terminal at each current location like the BT base station. On the other hand, the first and second embodiments do not function in an area where the BT base station does not exist. Therefore, in this embodiment, the GPS
By complementing both functions of BT and BT, good results are obtained.

In the process of FIG. 10, after starting the destination monitoring, the GPS function is activated to sequentially confirm the current position (S6).
1) It is checked whether the destination area has been reached (S62). The destination area is a range that is sufficiently larger than the communication area of the BT base station, for example, a radius of several hundred meters to 1 to several kilometers centered on the destination, or a range specified by the user. Is. When the destination area is reached, the process proceeds to step S64. If GPS reception is impossible even in the destination area (S63, No), the process proceeds to step S64.

In step S64, the BT function is activated to communicate with the base station when it enters the communication area of the base station (S65). The power of the BT unit is shut off until the BT function is activated to eliminate unnecessary power consumption. Communication with the base station is the same as that described in the first and second embodiments. When it is outside the BT communication area (S66,
No), the process returns to step S61, and the GPS function is used again.

Whether or not the vehicle has arrived at the destination is determined based on the information received from the base station in the BT communication area (S67). If not, the process returns to step S64. When the destination is reached, the user is notified to that effect (S6).
8). The notification form may be any of the above.

Regarding the communication with the BT and the notification to the user in the present embodiment, any of the first and second embodiments can be used.

Although the preferred embodiments of the present invention have been described above, various modifications and changes other than those mentioned above can be made. For example, instead of the GPS function for detecting that the destination area is reached in the third embodiment, the information of the base station of the mobile phone may be used. Further, although the description has been made only about the case where the destination information is acquired from the WEB server, it is also possible to select and use a destination previously stored in the mobile terminal as a main destination. Further, the user may obtain desired destination information from a printed matter such as a magazine or various display information and manually input it. Although BT has been mentioned as the short-range wireless communication means, other communication means such as a wireless LAN can be used.

[0052]

According to the present invention, since a base station for short-range wireless communication, which has a communication area limited to a relatively small range, is used, a position detection error is relatively small and a telephone base station is used. It can also be used in places where the radio waves do not enter.

Further, by successively obtaining the position information from the base stations existing on the route on the way to the destination,
It is possible to provide guidance on the degree of arrival at the destination at an intermediate stage until reaching the destination. On this occasion,
If the map information of the surroundings of the base station is given from the base station to the terminal, it is possible to provide more easily understandable guidance.
