Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information terminal such as a mobile phone, a pager, or a personal computer connected to a line, and more particularly to an information terminal that provides information regarding the location of the terminal owner.
[0002]
[Prior art]
With the development of information terminals such as mobile phones, personal handy-phone systems (PHS), and portable personal computers with built-in modems, communication using radio is rapidly spreading. In particular, mobile phones such as mobile phones and PHS have been widely used. Since these mobile phones use radio stations to make calls, you can make calls from anywhere on conventional phones that are fixedly installed in each location, and where mobile phone users can go. It has an excellent feature that it can make a phone call.
[0003]
However, the widespread use of such mobile phones has caused various problems. First, the occurrence of noise due to ringtones and spoken voices due to the use of mobile phones in public institutions such as trains, venues such as concerts, and hospitals where noise is a problem has been pointed out as a problem. In particular, sudden ringtones on trains and buses awaken sleeping people and have been pointed out as a major problem since the beginning of the appearance of mobile phones. Also, the parties to the phone are having a two-way conversation with the other party, but those around him who hear only the one-way conversation of the speaker say, "Isn't he talking to me?" Listening to it with the feeling that "the other party doesn't reply" makes you feel unstable.
[0004]
Several improvements have been proposed for incoming calls in this problem. One is a device for making the ringtone into a melody and eliminating the messiness of a normal telephone ringing tone. However, since it is assumed that the ringtone is a sound for the person to notice the incoming call, the problem does not change in that surrounding people are also aware of this and are inconvenienced. As another proposal, as disclosed in Japanese Patent Application Laid-Open No. 08-223257, a vibrator is attached to a mobile phone, and when a call is received, it is driven to notify the user of the incoming call by vibration. This devise does not bother the third party with the incoming call. However, since a person sitting next to you on a train etc. suddenly speaks out, people around you need to clarify whether this is accompanied by the occurrence of danger due to madness, and I happened to be there. As a person, it will cause great trouble.
[0005]
Therefore, in Japanese Patent Laid-Open No. 10-107915, when there is an incoming call in a public place such as a train, a guidance to make a voiceless call is sent to the other party, and then “Yes” assigned to each by operating the numeric keypad. By sending simple words such as "No", "Please ask again" to the other party with a synthesized sound, a silent call is possible. Japanese Patent Laid-Open No. 10-200266 also discloses a similar technique. Japanese Laid-Open Patent Publication No. 6-097878 also discloses a technique for silent communication, and records the caller's call content.
[0006]
In addition, Japanese Patent Application Laid-Open No. 05-2761081 solves the problem by transferring the incoming call to another predetermined place such as a home under the same situation.
[0007]
[Problems to be solved by the invention]
Certainly, many problems associated with incoming calls of mobile phones in public places can be avoided by the devices described above. However, mobile phones used particularly when using transportation such as trains and buses often confirm the current location. Information such as “Now Shinjuku Station” or “Passing Shimokitazawa” can be obtained.
[0008]
However, in voiceless communication such as that disclosed in Japanese Patent Application Laid-Open No. 10-107915, a user of a portable telephone in a transportation facility such as a train can send only a standard message such as “Yes” or “No” to the other party. In order for the other party to be able to know the location, it is necessary for the other party to perform a series of questions on the quiz program. In such a case, recording a message such as “Tell me your location” is not worth it.
[0009]
As described above, the problem of the response by the mobile phone in a place where speech cannot be performed has been described. However, there is a common problem in the case where it is impossible to speak. This is the case when a call is made to a mobile phone during work, but the call is prohibited or, in extreme cases, the phone has fallen due to a heart attack.
[0010]
Furthermore, I want to know the current position of a demented elderly person, a person such as an infant or a foreigner who cannot accurately express their position, or a person under probation, if necessary. Requests are in various places.
[0011]
Although the conventional problems have been described mainly with respect to mobile phones, electronic devices such as portable personal computers with built-in modems also exhibit the same functions as mobile phones by using their voice input / output functions. , And cause similar problems. Therefore, the portable telephone and these small electronic devices are collectively referred to as an information terminal in this specification.
[0012]
Therefore, an object of the present invention is to provide an information terminal capable of presenting information about the behavior of the user of the terminal or the current location.

DETAILED DESCRIPTION OF THE INVENTION
[0024]
【Example】
Hereinafter, the present invention will be described in detail with reference to examples.
[0025]
FIG. 1 is a diagram for explaining an outline of an information terminal system according to an embodiment of the present invention. In this information terminal system, a plurality of radio stations 101 connected to an electronic exchange (not shown) as in the current mobile phone communication system.₁, 101₂, 101_ThreePresuppose the existence of. In addition to this, this information terminal system uses a GPS (global positioning system) satellite 102. A GPS satellite 102, together with a similar GPS satellite 102 (not shown), receives radio waves from at least three or four satellites, performs two-dimensional or three-dimensional position measurement, and reads a rectangular area having a side of about 100 m. It can be done.
[0026]
The present embodiment deals with communication of location information without a voice in a train 104 traveling on a predetermined route 103. As already explained, many of the calls from users who use transportation such as the train 104 and the reception of these users are as follows: `` Which route runs before reaching the destination '' This is done for the purpose of transmitting or obtaining information that "passing through the station". In the present embodiment, the position information acquired by the information terminal is converted into the route information of the route 103, such information is created, and this is transmitted to the other party by silence. In order to automatically obtain current location information, a plurality of wireless stations 101₁, 101₂, 101_Three... And GPS satellites 102 are used. Of course, it may be one of the two, or the user may manually input the current location.
[0027]
FIG. 2 shows the appearance of the wireless terminal used in this embodiment. The wireless terminal 108 has an appearance close to that of a pager, and has a simple configuration including an antenna 201, a display 202 constituted by a liquid crystal screen, and an operation key unit 203. In the operation key unit 203, a plurality of function keys are arranged in addition to the numeric keypad 204. The rightmost key among these is the transmission key 205, and transmission is automatically performed when this key is pressed. The numeric keypad 204 is used for specifying a transmission destination, selecting information displayed on the display 202, and inputting numerical values, characters, and the like.
[0028]
FIG. 3 shows an outline of the configuration of the information terminal system using the wireless terminal of this embodiment. In this information terminal system, the first wireless station 101₁, Second radio station 101₂And the third radio station 101_ThreeAre connected to the radio station controller 214 via predetermined communication cables 211, 212, and 213, respectively. The electronic switching device 215 is connected to a terminal control device 216 for controlling each wireless terminal together with the wireless station control device 214. Another electronic exchange device 218 connected to the communication network 217 is connected to the desktop personal computer 109 shown in FIG. 1 via a communication control device 219 such as a router.
[0029]
First to third radio stations 101₁~ 101_ThreeAre the first to third transmission / reception areas 221, respectively.₁~ 221_Three, 222₁~ 222_Three223₁~ 223_ThreeIt has. In the figure, the first to third radio stations 101 are shown for the sake of simplicity.₁~ 101_ThreeThese transmission / reception areas 221₁~ 221_Three, 222₁~ 222_Three223₁~ 223_ThreeHowever, in reality, the wireless station 101 is arranged at various places so as to cover the respective places shown in FIG. 1 without any gaps, and the first to third transmission / reception areas 221 are provided.₁~ 221_Three, 222₁~ 222_Three223₁~ 223_ThreeAre arranged so as to overlap each other. Each wireless station 101₁~ 101_ThreeIs a plurality of transmission / reception areas 221 (three in this example, but not limited to this).₁~ 221_Three, 222₁~ 222_Three223₁~ 223_ThreeThe reason for this is to increase the number of terminals that perform communication in, for example, a CDMA (Code Division Multiple Access) system by subdividing the area.
[0030]
In this way, each wireless station 101₁~ 101_ThreeIs a transmission / reception area 221 like a mesh₁~ 221_Three, 222₁~ 222_Three223₁~ 223_Three,... Are arranged so that each wireless terminal 108₁, 108₂Can be analyzed on the radio station controller 214 side. Further, if the GPS satellite 102 is used, it is possible to grasp the current location with higher accuracy. In FIG. 3, the desktop personal computer 109 is used for creating a routing table, which will be described later.
[0031]
FIG. 4 shows an outline of the configuration of the terminal control apparatus shown in FIG. The terminal control device 216 includes a CPU (central processing unit) 231 that can also be used as a CPU mounted on the electronic exchange device 215. The CPU 231 is connected to a RAM (Random Access Memory) 233, a magnetic disk 234, a display control device 235, and an input circuit 236 via a bus 232 such as a data bus. Here, the display control device 235 is a circuit for visually displaying various information on the display 237 made of liquid crystal or CRT. The input circuit 236 is connected to a data input device such as a keyboard 238. The magnetic disk 234 stores a program for performing overall control of the terminal control device 216, which is expanded in the RAM 233 and executed. The magnetic disk 234 stores various types of information such as various route maps such as railroads and buses, position information of stations and stops, correspondence tables indicating the relationship between the residential display of cities, towns and villages, and longitude and latitude, and timetables. Note that the terminal control device 216 may be connected to a communication network that acquires actual arrival / departure information such as vehicles of various transportation facilities.
[0032]
Note that the wireless terminal 108 shown in FIG. 2 has the same configuration as that of a portable pager in principle, and thus the illustration and description of the configuration are omitted. The wireless terminal 108 includes a detection circuit for detecting the current location using GPS, but a position data detection mechanism using GPS is not necessarily required depending on the apparatus. Each wireless station 101₁~ 101_ThreeIn such a case, rough position data can be acquired in relation to,.
[0033]
FIG. 5 shows the main part of the route map near Tokyo. This will be described with reference to FIG. 1 and FIG. For example, the wireless terminal 108 shown in FIG.₁User 107 sent to their family by car to Odakyu Line “Noborito Station”, then went to “Shinjuku Station”, changed to Marunouchi Line, and went to a company near “Akasaka Mitsuke Station” Shall. On the other hand, return to “Noborito Station” in reverse, and from here the family will carry it to their home by private car. In such a case, it is necessary for the family to meet at “Noborito Station” in a timely manner according to the time of return. For this purpose, the wireless terminal 108₁A location confirmation service is provided. In order to use this location confirmation service, the user 107 registers a route to be used as necessary, and selects a route to be used from the registered route.
[0034]
FIG. 6 shows the contents of the route table registered by the user. The route table 241 is stored in the wireless terminal 108 carried by the user 107.₁Of the non-volatile memory (not shown). Wireless terminal 108₁Since the configuration itself is almost the same as that of a simple personal computer, description thereof is omitted.
[0035]
The route table 241 is created by the wireless terminal 108.₁It can be created by opening a creation menu on the display 202 or using the desktop personal computer 109 at home or office. In the latter case, the created route table or the data related to the route to be added is transmitted to the wireless terminal 108 using an infrared communication device.₁If the mobile terminal has its own telephone number, the wireless terminal 108 is used by using the telephone communication network.₁Can be sent to.
[0036]
A typical route can be selected from the created route table 241. Also, if you arrive at your destination through a new route, use software such as commercially available software that determines the route of transportation such as railways and buses. "Can be entered to determine the route, and this can be set as the route to be taken this time. Such software does not necessarily have its own wireless terminal 108.₁The terminal control device 216 shown in FIG. 3 may be prepared. Furthermore, when there is a situation in which a route cannot be selected as in the case of a deaf person, a plurality of possible routes may be set as a logical sum in advance. Similarly, if you do not know whether you are going from the Akasaka headquarters to Saitama or Yokohama, you can set up multiple routes.
[0037]
Before getting on the train, the user 107 is connected to the wireless terminal 108.₁Is set to a special mode called position information automatic response mode. In this mode, the current location of the user 107 is automatically notified to the caller only when a call is made from a telephone having a preset telephone number. Of course, such a notification of the present location may be given to all who have made a call without any restriction. It is also possible for the user 107 to automatically notify a specific telephone number of the current location by operating the button switch 205 (FIG. 2). When the position information automatic response mode is set, the indicator 208 shown in FIG. 2 blinks.
[0038]
FIG. 7 shows a state of control when an incoming call is received in a state where the wireless terminal owned by the user is set to the position confirmation service mode. First, when there is an incoming call (step S261: Y), the CPU in the wireless terminal determines whether or not this location confirmation service is for a specific person (step S262). That is, when the user 107 is set to provide this service only to specific persons (Y), it is checked whether or not the telephone number received matches those of the specific persons. If it does not match (N), a message such as “I cannot answer the phone now” is sent (step S264), and then the line is disconnected.
[0039]
On the other hand, if the incoming telephone number matches the telephone number registered for the location confirmation service (step S263: Y), or if the target of this service is an unspecified person, the wireless terminal 108₁Acquires the current position data (step S266). Then, the corresponding station name in the route selected in advance from the route table 241 is discriminated (step S267), additional information such as the station name is added to the standard message and transmitted to the other side (step S268), and the line is disconnected. (Step S265).
[0040]
FIG. 8 shows the flow of additional information creation processing. Wireless terminal 108 shown in FIGS. 1 and 3₁Is a plurality of wireless stations 101₁, 101₂, 101_Three,... Wireless station 101 to which the radio reaches₁Is connected to the wireless station control device 214 via which the terminal control device 216 of the electronic exchange device 215 is controlled. As described above, the terminal control device 216 includes various types of information such as various route maps such as railways and buses, position information of stations and stops, correspondence tables indicating the relationship between the residential display of cities, towns and villages, and longitude and latitude, and timetables. Stored. The wireless station control device 214 is in the position confirmation service mode and the wireless terminal 108₁Radio waves transmitted by the wireless terminal 108 are received at predetermined time intervals.₁Is monitored whether or not the vehicle stops at a fixed position (step S281). Here, the wireless terminal 108₁Whether or not the radio station is stopped is determined by a plurality of radio stations 101₁, 101₂, 101_Three, ... in the wireless terminal 108₁It is possible to determine whether or not the station that can receive the radio wave of the current position or the position obtained by the intensity of the radio wave received by those stations moves in time. In a situation where position information using the GPS satellite 102 can be acquired, the wireless terminal 108 is used.₁It can also be determined by the presence / absence of a change in position information sent from.
[0041]
Wireless terminal 108₁Is stopped at the fixed position (step S281: Y), it is determined whether it corresponds to any station on the selected route (step S282). Correspondence with the station is performed based on whether or not the position of each station on the selected route is included in the position range recognized as the current location. When it is certain that you are on a certain railroad based on history information or route selection information, you can specify the position in front of and through the station even if it is impossible to accurately identify one station. As a result, it is possible to determine with a considerable probability whether the vehicle has stopped or passed through the station. As a result, if the user is stopped at any station (Y), the section of the route such as railroad or bus is compared with the timetable (step S283). If there is no incoming call at this time (step S284: N), the process returns to step S281 again to monitor the movement status of the user 107. When such a monitoring state continues, for example, “I get on a train from Shinjuku Station at XX hour and stop at Yoyogi Uehara Station and Shimokitazawa Station on the way, and now I am passing through Kyodo Station.” The movement situation can be grasped. In addition, if data such as the station name of the stop station and the stop interval are used, it can be estimated that the train seems to be an express train or a semi-express train. Of course, if the train is operating according to the timetable, it can be determined that the train is an express train.
[0042]
Furthermore, if the end point of the selected route is “Noborito Station”, it is also possible to estimate the time to reach “Noborito Station” by applying the timetable and the required time between stations. Furthermore, when the arrival time of each station is significantly different from the departure time, or when it is determined that the train has stopped for a relatively long time on the way, “the train is delayed for some reason”. Judgment is also possible. In such a case, it may be possible to determine the correction of the arrival time in anticipation of the train delay.
[0043]
Therefore, when there is an incoming call (step S284: Y), the terminal control device 216 presents additional information such as the name of the route on the set route, the departure time, the type of train such as express, etc. It is set as additional information together with the time information (step S285). This additional information includes the wireless terminal 108 together with information obtained by replacing the current position with the station name.₁Will be sent to the other party. The transmission to the other party may be performed with synthesized sound or may be transmitted as text information. Some examples are as follows.
[0044]
“I am on the Odakyu Line as of 18:20 and have passed Kyodo Station. After leaving Akasaka Mitsuke Station, I am on the express train departing at 18: 6 at Shinjuku Station. It is expected to arrive at Noborito Station at 35 minutes.
“I am on the Odakyu Line as of 18:30 and have passed Kyodo Station. It seems that I am on an express or semi-express train from Shinjuku Station at 18:00. I was expecting to arrive at Noto Station at 18:25, but will be delayed after 18:40.
[0045]
In the embodiment described above, the transmission of a message for an incoming call when the position confirmation service mode is set has been described. However, a similar message is sent to a specific destination from a user 107 in the middle of a route by a dial operation. Alternatively, it is naturally possible to make a call by simply pressing the send key 205 for a predetermined telephone number. These messages are also transmitted before the wireless terminal 108 before transmission.₁It is also possible to display the image on the display 202 and send it after correcting it if necessary. In the embodiment, various data are stored in the terminal control device 216 connected to the electronic switching device 215 to control the location, etc., but all or part of such control is performed on the information terminal side. Or can be performed in a communication network or other places on the network.
[0046]
There may be a case where the user 107 does not travel along the selected route. If another route is determined instead of such a case, the location on the route is determined, but such a route may not be determined. In such a case, since the corresponding station (or a stop or a landmark registered in advance) does not exist, normal residence display is performed. In other words, a message such as “I am at 2-4 Yoyogi, Shibuya-ku after getting off the station” is sent out. Also, if a location such as “Company A” shown in the route table 241 of FIG. 6 is registered in association with the position information, a message such as “I am now at Company A”, “I was at Company A from 10:30 to 11:30, but I took the Yamanote Line from Shibuya Station and passed Yoyogi Station as of 12:30.” Or “I'm home at 17:00.” It is also possible to send such a message. Of course, a message for the current location may be simply sent according to the telephone number of the caller, or information on all routes traced in one day may be sent as a message. Such modifications can be understood without explaining the details.
[0047]
Furthermore, even if the user does not create or select the route table 241 in particular, if the item “Train, Bus” is selected from the menu screen displayed on the display 202 or the dedicated function key, every moment. It is also possible to compare the obtained position information of the user with a train or bus route, determine the route and the name of the station, or the name of the stop, and notify it. As a result, it is possible to notify the other person of his / her whereabouts and the route taken without causing any trouble to others in the train or the like.
[0048]
Also, for each route in the route table, especially routes such as bus routes and promenades, you can register landmarks such as city halls, XX parks, and XX department stores corresponding to the location data, or as map data If prepared, such a place can be transmitted as the corresponding place, and the data receiving side can intuitively grasp the position of the user of the information terminal.
[0049]
In particular, if the source's own display or destination's display shows the location of each station, stop, road, etc. on the route as appropriate on the horizontal axis, the route traced up to the present is displayed in a bar graph , It is easy to understand or understand how far the entire path has come. That is, when it is desired to know whether or not the destination is approached, such as when riding on a train on an unknown land, the wireless terminal 108₁If such information is displayed on an information terminal, etc., it is possible to grasp the position of the person in the transportation system regardless of whether or not the information is transmitted to another person. Therefore, if you set the route yourself and specify the getting-off station, it is a device that prevents you from overpassing by means such as vibrating the vibrator near the station or generating a warning sound from the earphone The present invention makes it possible to make various modifications.
[0050]
In the embodiment, an example in which an information terminal similar to a pager is used has been described. However, the present invention can be applied to all information devices that can communicate with each wireless station and can acquire and determine position data using GPS. Of course it is applicable. In particular, mobile phones can be expected to be widely applied because they can notify the user's location without sound.
[0051]
【The invention's effect】
  As described above, according to the first aspect of the present invention, the position data representing the current position is acquired by the position data acquisition means, and corresponds to the position on the movement route set by the movement route setting means. If applicable, the location data is converted to the corresponding location on the travel route, and the information indicating the converted location is sent to a specific destination. You will know where you are.In addition, if the route does not correspond to the set route, it is not converted into coordinate data representing the position, but converted into a more easily distinguishable housing display and output, so a relatively easy-to-understand location display is output. In addition, you can guess the situation of getting off a train or bus, using a taxi or walking.
[0052]
Further, in the invention described in claim 2, the movement route discriminating means for discriminating which movement route is stored in the other movement route information storage means capable of obtaining the same effect as that of the invention described in claim 1. Since it is provided, it is possible to determine the movement route by taking the logic of the position data even when the movement route is not particularly specified. Therefore, even if it is unclear as to a deaf person or a child, it is possible to identify the route and notify this to the other party in an easy-to-understand place display.
[0054]
  Further claim 3According to the described invention, not only the current location but also the information of where you were in the past is also notified, so when you get on a transportation like a train, which direction you are heading, the train is delayed Additional information can also be notified.
