Description

  According to the present invention, when a call signal is transmitted from a subscriber's mobile phone terminal registered in advance to a specific phone terminal, the position of the subscriber is determined based on the position of the base station that received the call signal. The present invention relates to a position notification system that estimates and notifies a specific contact.

Conventionally, when a subscriber uses a mobile phone to make an emergency call to a specific contact, such as the police (110), the location of the base station nearest to the mobile phone is the location of the subscriber. There is known an information notification system that notifies In this information notification system, a network management station is connected to a mobile phone network, a subscriber makes an emergency contact from a mobile phone to a specific contact, and the mobile phone network passes through the nearest base station. When the network management station is connected, the network management station identifies the position of the base station, and automatically notifies the contact information registered in the network management station of the position of the identified base station. (For example, see Patent Document 1 etc.)
JP 7-183970 A

  However, in the information notification system, what is transmitted to the contact address when contacting is not the actual position of the subscriber who owns the mobile phone, but the position of the base station. Therefore, the contact person who received the contact cannot accurately specify the position of the subscriber who made the contact. And when the communication by the mobile phone is such that the occurrence of the crime is informed, the purpose of carrying out rescue activities at an early stage may not be achieved.

  The present invention has been made in view of these problems, and when a call is made from a subscriber's mobile phone terminal to a specific phone terminal, the location of the subscriber who made the mobile phone is accurately estimated and specified. It is an object of the present invention to provide a location system that notifies a contact person of a location.

  In order to achieve this object, the invention according to claim 1 receives a call signal when a call signal for a specific telephone terminal is transmitted from a mobile telephone terminal of a subscriber registered in advance. A location notification system for estimating the location of a subscriber based on the location of a base station of the mobile phone network and notifying a specific contact address, and for each subscriber of the system, a mobile phone owned by the subscriber Subscriber information storage means in which terminal identification information and stop-by information representing a plurality of stops to which the subscriber will stop are registered in association with each other, and connected to the mobile phone network, and subscriber information storage means Calling state monitoring means for monitoring whether or not a calling signal for a specific telephone terminal is transmitted from the mobile telephone terminal owned by the subscriber of the system based on the identification information of the mobile telephone terminal registered in Calling state supervision When it is detected by the means that a call signal for a specific phone terminal is transmitted from a mobile phone terminal owned by a subscriber of the system, the base station that has received the call signal is The nearest stop to the base station is extracted from the stop information registered in the subscriber information storage means in association with the subscriber who is the owner of the mobile phone terminal that has identified and transmitted the call signal And a location notification means for transmitting the extracted stop as location information indicating the location of the subscriber to a specific contact.

  According to the position notification system configured as described above, when a previously registered subscriber makes a call from a mobile phone terminal to a specific phone terminal, the call status monitoring means transmits a call signal transmitted from the mobile phone terminal. Is detected. Then, when the call state monitoring means detects the call signal, the location notification means identifies the base station that has received the call signal, and the subscriber's stop information stored in the subscriber information storage means The stop nearest to the specified base station is extracted from the inside, and the stop is transmitted to a specific contact (for example, 110) as the location information of the subscriber.

  Therefore, since the location where the subscriber is likely to be present (the location registered as the subscriber's location information) is transmitted as location information, the location of the base station is transmitted as the location information of the subscriber. Compared with the conventional system, it is possible to notify the exact location of the subscriber. Then, when the communication by the mobile phone is such that the occurrence of the crime is notified, it is possible to perform a quick and accurate rescue operation based on the transmitted position information.

  By the way, in the case of emergency contact, the telephone terminal that can be called from the mobile phone terminal may be predetermined such as 110. However, not only the phone terminals that are determined in advance, but also the location information is transmitted when a call is made to another phone terminal (for example, home), the subscriber wishes This is convenient for subscribers because location information is transmitted when a call is made to a telephone terminal. Therefore, as described in claim 2, the subscriber information storage means is configured so that the monitoring information indicating the calling signal to be monitored by the calling state monitoring means can be registered for each subscriber. Based on the identification information and monitoring information of the mobile phone terminal registered in the subscriber information storage means, the monitoring means transmits a call signal set for each subscriber from each subscriber's mobile phone terminal. It is recommended to monitor whether or not.

In this way, when a call signal is transmitted from the subscriber's mobile phone terminal to the monitoring information registered in the subscriber information storage means, the location information is transmitted to a specific contact.
Therefore, if the subscriber registers the monitoring information of the home telephone terminal in the subscriber information storage means, for example, when the telephone is called to the home telephone terminal (instead of the predetermined 110), The subscriber's location information is sent to a specific contact. That is, even when the subscriber makes a call to a telephone terminal other than a predetermined telephone terminal, the location information can be transmitted to a specific contact address, which is a convenient system for the subscriber.

  Further, if there are a plurality of telephone terminals other than the predetermined telephone terminal, if there is a plurality of telephone terminals, if one of the telephone terminals is called, the location information is transmitted to a specific contact point, which is convenient. Therefore, as described in claim 3, the subscriber information storage means is configured so that a plurality of outgoing signals to be monitored by the outgoing call state monitoring means can be registered as monitoring information for each subscriber. The call state monitoring means includes a plurality of call signals set for each subscriber from each subscriber's mobile phone terminal based on the identification information and monitoring information of the mobile phone terminal registered in the subscriber information storage means. It is preferable to monitor whether or not any of the above has been transmitted.

  In this way, if the calling signal transmitted when the subscriber calls the telephone terminal is one of a plurality of calling signals registered in the subscriber information storage means, the subscriber Location information is sent to a specific contact.

  Accordingly, if the subscriber registers, for example, monitoring information of a plurality of telephone terminals such as homes or offices in the subscriber information storage means, any one of a plurality of telephone terminals other than the predetermined telephone terminals is registered. If you place a call, the location information will be transmitted, making the system more convenient for the subscriber.

  The contact information to which the location information is transmitted is not limited to a specific contact address (for example, at home), but is sent to other contact information. Since the location information can be transmitted to the subscriber, it is convenient for the subscriber. Therefore, as described in claim 4, the subscriber information storage means is configured to be able to register, for each subscriber, a contact address to which the position of the subscriber is to be communicated. When the extracted stop is transmitted as the location information of the subscriber, the contact information corresponding to the subscriber is read from the subscriber information storage means, and the location information of the subscriber is transmitted to the read contact information. Good.

  In this way, when the subscriber calls a specific telephone terminal, the location notification means transmits the location information of the subscriber to the contact information registered in the subscriber information storage means. Accordingly, the position information can be transmitted to a contact other than the predetermined specific contact. That is, since the subscriber's desired contact information can be notified of the location information of the subscriber, the system is convenient for the subscriber.

  Further, according to the fifth aspect, the subscriber information storage means corresponds to a plurality of call signals registered as monitoring information, and a contact address to be informed of the location of the subscriber is set for each subscriber. The location notifying unit is configured to be able to register a plurality of locations, and the location notifying unit detects from the subscriber information storage unit the call state monitoring unit detected when transmitting the destination extracted from the destination information as the location information of the subscriber. When a contact corresponding to the call signal is read and the subscriber's location information is transmitted to the read contact, a plurality of registered call signals (in other words, a plurality of registered telephone terminals) are registered. Corresponding to each, location information can be transmitted to different contacts.

That is, the subscriber's location information can be transmitted to a plurality of contacts desired by the subscriber, which makes it a convenient system for the subscriber.
By the way, when an emergency occurs, a call signal may be transmitted many times from the same mobile phone to a specific telephone terminal within a relatively short time. In order to deal with such a situation, it is preferable to count the number of call signals transmitted from the same mobile phone terminal to the same phone terminal within a predetermined time and notify the counted number. That is, as described in claim 6, once the call state monitoring means detects a call signal transmitted from a mobile phone terminal owned by a subscriber to a specific phone terminal, within a predetermined time thereafter The call state monitoring means is provided with a call signal count means for counting the number of times that the call signal is detected, and the position notifying means transmits the stop destination extracted from the stop destination information as the location information of the subscriber. In addition to the location information indicating the location of the subscriber, the number of calls detected by the call count counting means may be transmitted to the specific contact.

  If it does in this way, the frequency | count of detection of the call signal counted by the call frequency count means within the predetermined time will be transmitted to a specific contact by the position notification means. Therefore, the contact where the location information is received can know how many times the subscriber has made a call to a specific phone terminal within a certain period of time, and the urgency of the contact and the urgency of the incident Information can be obtained.

  In addition to emergency contact, there is a case where it is desired to send a message corresponding to a subscriber's location to a specific contact. For example, when a student enters or leaves a school, the parent is notified that the student has gone to school, or the parent / guardian is informed of whether the student has been withdrawn from school or not. In order to cope with such a case, as described in claim 7, the subscriber information storage unit is configured to store a calling signal counted by the calling number counting unit for each of a plurality of stops of each subscriber. It is possible to register message information representing a message associated with the number of detections, and the position notification means corresponds to the stop destination extracted from the stop-by information and the number of detections of the call signal counted by the call count counting means. The message extracted from the message information is transmitted as the location information of the subscriber, and the extracted message is transmitted to a specific contact instead of the location information. Good.

  In this way, the number of “detection of call signal transmitted by subscriber to mobile phone terminal to specific telephone terminal” (in other words, the number of times the subscriber made a call from the mobile telephone terminal to the specific telephone terminal) and Since an appropriate message is transmitted to a specific contact based on the subscriber's stopover, the location notification system can be used for subscriber safety management or the like.

  For example, when a student who is a subscriber makes a call from a fixed place to a fixed place, such as when a student calls a telephone terminal at home from a school, a message corresponding to the number of detected call signals (for example, , "I went to school" when I went to school (the first transmission), "I'm going to go to school" when I left school (the second transmission)) was sent to a specific contact (for example, a parent's mobile phone) Therefore, the parents can grasp the behavioral status of the student and can manage the student safety.

Embodiments of the present invention will be described below with reference to the drawings.
(Embodiment 1)
FIG. 1 is a schematic configuration diagram showing a configuration of a location notification system 1 to which the present invention is applied, together with a telephone network to which the location notification system 1 is connected.

  As shown in FIG. 1, the location notification system 1 is connected to a central exchange 25 installed in a mobile telephone network 20, and processes emergency contact and leaving / exiting based on outgoing call information obtained from the central exchange 25. And a subscriber information database (hereinafter also referred to as subscriber information DB 45) stored in the storage device of the management computer 40. In addition, the subscriber information DB 45 includes identification information 45a in which information for identifying the mobile phone terminal 10 of each subscriber is registered for each subscriber, and stop-by information of the contact is associated with the identification information 45a. The registered stop information 45b, the monitor information 45c in which the monitor information for monitoring the call destination of the call signal from the mobile phone terminal 10 is registered for each subscriber, and the subscriber's stop The contact information to be transmitted is composed of contact information 45d registered in association with the monitoring information.

  Further, the location notification system 1 is connected to the mobile telephone network 20, the mobile phone 10 connected thereto, the public telephone network 35, the telephone 8 b connected thereto, and the command center 60 via the central exchange 25 connected to the central computer 40. Or the Internet 30 or a mobile phone terminal 6a connected thereto.

Further, the command center 60 and the police station 65 are connected by radio or the like, and the police station 65 receives commands from the command center 60 by radio or the like.
Here, the subscriber information DB 45 will be described in more detail with reference to FIG.

  As shown in FIG. 2, in the subscriber information DB 45, identification information 45a and monitoring information 45c are registered for each subscriber, and further, stop-by information 45b is registered in association with each identification information 45a. In addition, contact information 45d is registered in association with each monitoring information 45c.

  The identification information 45a is identification information (for example, a telephone number) for identifying the mobile phone terminal 10 that has transmitted a call signal (in other words, made a call). In the first embodiment, each subscriber One is registered for each.

  The stop-by information 45b is information (for example, relatives, schools, cram school addresses, etc.) for specifying the stop-by of the subscriber, and is registered in association with each identification information 45a. In the first embodiment, up to three pieces of information can be registered for each piece of identification information 45a.

  The monitoring information 45c is information (for example, the telephone number of the call destination) for monitoring the call destination of the call signal from the mobile phone terminal 10. In the first embodiment, three pieces of information are provided for each subscriber. You can register up to.

  The contact information 45d is contact information (for example, a home or relative phone number or an e-mail address of a home personal computer or mother's mobile phone terminal) to which the subscriber's stop-by information should be transmitted. It is registered in association with the monitoring information 45c. In the first embodiment, up to two pieces of information can be registered for each piece of monitoring information.

Next, the operation of the position notification system 1 configured as described above will be described including the operation of the telephone network and each terminal.
First, when a subscriber makes a call by operating the mobile phone terminal 10, a call signal is output from the mobile phone terminal 10, and the output call signal is received by the base station 15. 15 is sent to the central exchange 25 of the mobile telephone network 20 to which the terminal 15 is connected.

  The central exchange 25 extracts the call destination from the received call signal, and if the call destination is a mobile phone on the same mobile phone network 20, the mobile phone network 20 is connected so that the line is connected to the mobile phone. (So-called telephone exchange). If the call destination of the call signal is a telephone on the public telephone network 35, line connection is made between the mobile telephone network 20 and the public telephone network 35 so that the line is connected to the telephone. Further, when an electronic mail is transmitted from the mobile phone 10, the electronic mail is transmitted to the transmission destination address via the Internet 30 as a mail server.

  The management computer 40 monitors the central exchange 25. When the central exchange 25 receives the call signal, the management computer 40 obtains the call signal from the central exchange 25, and from the call signal, the telephone number of the cellular phone terminal 10 is obtained. The telephone number of the call destination is extracted.

  Next, the management computer 40 searches the identification information 45a for the extracted telephone number of the mobile phone terminal 10. If the telephone number is registered in the identification information 45a as a result of the search, the location of the base station 15 that received the call signal is specified, and the subscription registered in association with the telephone number of the mobile phone terminal 10 The nearest stop to the location of the base station 15 is searched and extracted from the stop destination information 45b.

  Further, the management computer 40 searches the monitoring information 45c for the telephone number of the call destination extracted from the call signal. As a result of the search, when the telephone number of the call destination is registered in the monitoring information 45c, the transmission destination associated with the telephone number is searched and extracted from the contact information 45d.

  Then, the management computer 40 transmits, via the central exchange 25, the stop location extracted from the stop location information 45b as the location information of the subscriber to the destination extracted from the contact information 45d.

  In this way, according to the location notification system 1, when the subscriber places the mobile phone 10 on the telephone number registered in the monitoring information 45c, the current location of the subscriber is extracted from the stop information 45b, It is transmitted to the contact registered in the contact information 45d. Therefore, the contact that has received the stop can take necessary measures based on the received stop.

  For example, when the telephone call from the mobile phone terminal 10 is an emergency call to 110 (calling destination), the stop of the subscriber of the mobile phone terminal 10 is displayed on the telephone (contact address) of the command center 60. Since it is transmitted, the command center 60 commands the police station 65 close to the subscriber's stop to send out a dispatch command or the like by radio or the like.

Next, emergency contact processing executed by the management computer 40 in the position notification system 1 operating as described above will be described with reference to FIGS.
3 and 4 are flowcharts showing the flow of emergency contact processing executed by the management computer 40. FIG.

  The emergency contact process shown in FIGS. 3 and 4 is started when the management computer 40 is powered on. After the startup, first, in S100, it is determined whether or not the central exchange 25 has received a call signal. Monitor. If the central exchange 25 has not received a call signal (No in S100), monitoring is repeated, and if a call signal is received (Yes in S100), the process proceeds to S105.

  In S105, a call signal is acquired from the central exchange 25. Then, the process proceeds to S110, where the telephone number of the mobile phone terminal 10 is extracted from the acquired call signal and stored, and in S115, the call destination telephone number is extracted from the call signal and stored. Migrate to

  In S120, the telephone number of the mobile phone terminal 10 stored in S110 is searched from the identification information 45a in the subscriber information DB 45. If the telephone number is not in the identification information 45a (in the case of No in S120), S100 Returning to, the emergency contact process is repeated, and if the telephone number is in the identification information 45a (Yes in S120), the process proceeds to S125.

  In S125, the telephone number of the call destination of the calling signal is searched from the monitoring information 45c, and if the corresponding telephone number is not in the monitoring information 45c (No in S125), the process returns to S100 and this emergency contact process is performed. repeat. Conversely, if the corresponding telephone number is in the monitoring information 45c (Yes in S125), the process proceeds to S130.

  In S130, it is determined whether or not the phone number of the mobile phone terminal 10 stored in S110 is the same as the phone number of the mobile phone terminal 10 extracted and stored from the previously received call signal. If YES in S130, the process proceeds to S135. If not the same (No in S130), the process proceeds to S160 in FIG.

  In S135, the call destination telephone number of the call signal stored in S115 is the same as the call destination telephone number of the call signal of the mobile phone terminal 10 extracted and stored from the previously received call signal. If it is the same (Yes in S135), the process proceeds to S140. If not the same (No in S135), the process proceeds to S160 in FIG.

In S140, the timer is counted up, and in subsequent S145, the number of calls detected is counted, and the process proceeds to S150.
In S150, it is determined whether the timer has reached a predetermined time. If the predetermined time has been reached (Yes in S150), the process proceeds to S155 in FIG. Is reset, and the process proceeds to S160.

In S160, the position of the base station 15 that has received the call signal from the mobile phone terminal 10 is specified, and the process proceeds to S165.
In S165, based on the telephone number of the mobile phone terminal 10, a contact is searched from the contact information 45d. If there is no corresponding contact (No in S185), the process returns to S100 and the emergency contact process is performed. repeat. Conversely, if there is a corresponding contact address (Yes in S185), the process proceeds to S170.

  In S170, from the specified location of the base station 15, the stop of the subscriber closest to the base station 15 is searched and extracted from the stop information 45b in the transmittable / receivable area of the base station 15. If there is a corresponding stop as a result of the search (Yes in S170), the process proceeds to S175, and the stop extracted in S170 is the mobile phone terminal 10 (in other words, the owner of the mobile phone terminal 10). The position is set and the process proceeds to S185. On the other hand, if there is no corresponding stop as a result of the search (No in S170), the process proceeds to S180, the position of the base station 15 is set as the position of the owner, and the process proceeds to S185. When setting the position of the owner, the position is used as data corresponding to the contact searched in S165. That is, if the contact is a telephone number, the position is set as voice data, and if the contact is an e-mail address, the position is set as character data.

In S185, the number of detection of the call signal counted in S145 is added to the position of the owner set in S175 or S180, and the process proceeds to S190.
In S190, if the contact is a telephone number, a call is made to the contact via the central exchange 25, and the owner's position set in S175 or S180 is communicated to the contact by voice. If it is an e-mail address, the position of the owner set in S175 or S180 is transmitted to the central exchange 25 by e-mail.

When S190 ends, the process returns to S100 and repeats the emergency contact process.
Note that the emergency contact process is terminated when the management computer 40 is powered off.

  According to the position notification system 1 described above, when the owner makes a call from the mobile phone terminal 10 to the telephone terminal registered in the monitoring information 45c of the subscriber information DB 45, the mobile phone terminal 10 is connected to the mobile phone network. The nearest stop to the base station 15 connected to 20 is extracted from the stop information 45b registered in the subscriber information DB 45, and the extracted stop is added as position information indicating the position of the owner. It is transmitted to the contact registered in the contact information 45d of the person information DB 45. In other words, in the location notification system 1, a stop-off location that is more likely to actually have a subscriber is notified as the location of the owner. Therefore, when the communication by the mobile phone terminal 10 is a notification of the occurrence of a crime, it is possible to perform a quick and accurate rescue operation based on the notified stop.

  Further, in the position notification system 1, when a plurality of calls are made from the same position to the same telephone terminal from the mobile phone terminal 10 within a predetermined time, together with the owner's position information (destination) The contact number is notified of the number of detected call signals within the predetermined time. Therefore, the contact who has received the location information of the owner can know how many times the owner has called the same telephone terminal from the mobile phone terminal 10 within a predetermined time, and the degree of urgency of the contact and the degree of urgency of the incident It becomes possible to obtain information on the urgency of communication.

By the way, the position notification system 1 can be used not only in emergency contact but also on a daily basis.
That is, in the position notification system, as shown in FIG. 2, as the monitoring information 45c to be registered in the subscriber information DB 45, in addition to the emergency call number 110, a telephone number such as a home or a relative is registered, and a stopover is also provided. The address of the private school, school or relative is registered as the destination information 45b.

Therefore, for example, if a child holds the mobile phone terminal 10 and makes a phone call to his / her home every time his / her place changes (such as when going from school to a cram school), the location (cram school, school, etc.) Since it is extracted from the information 45b and transmitted to the telephone 8b at home, the mobile phone terminal 6a or the personal computer 6c at home, the guardian can always know the position of the child.
(Embodiment 2)
Next, Embodiment 2 will be described with reference to FIGS. The location notification system 1 of the second embodiment further notifies the location notification system 1 of the first embodiment when the mobile phone terminal 10 contacts the same telephone terminal from the same stop within a predetermined time. In addition to notifying the number of times, a message corresponding to the number of times of contact is sent to the contact.

  More specifically, for example, when a student attending a cram school attends the cram school or returns home from the cram school, when the mobile phone terminal 10 makes a call from the cram school to the home 75, the student is different from the home. In this system, a message (for example, “I attended” or “I will return home”) corresponding to the student's exit / exit is transmitted to the mobile phone terminal 6a carried by the mother at the place.

  The location notification system 1 according to the second embodiment is different from the location notification system 1 according to the first embodiment in that message information 45e is added to the subscriber information DB 45, and the message information 45e is transmitted to the contact information. The difference is only in the point that the processing for the above is added, and the other configuration is the same, so that two points will be described below.

FIG. 5 is a diagram illustrating a configuration of the subscriber information DB 45 according to the second embodiment.
As shown in FIG. 5 (a), message information 45e transmitted to the contact information is added to the subscriber information DB 45 in addition to the identification information 45a, the stop-by information 45b, the monitoring information 45c, and the contact information 45d. ing.

  As shown in FIG. 5B, the message information 45e is associated with the call destination information 45b and the number of detections of the call signal transmitted from the mobile phone terminal 10, and a message (for example, the call destination is In the case of a cram school, messages such as “I attended” and “I'm going home” are registered.

6 and 7 are flowcharts showing the flow of contact processing executed by the management computer 40. FIG.
6 and 7 is activated when the management computer 40 is powered on. After the activation, first, in S300, whether or not the central exchange 25 has received a call signal is determined. To monitor. If the central exchange 25 has not received a call signal (No in S300), monitoring is repeated. If a call signal is received (Yes in S300), the process proceeds to S305.

  In S305, a call signal is acquired from the central exchange 25. Then, the process proceeds to S310, where the telephone number of the mobile phone terminal 10 is extracted from the acquired call signal. In the subsequent S315, the call destination telephone number of the call signal is extracted from the call signal, and the process proceeds to S320. To do.

  In S320, the telephone number of the mobile phone terminal 10 extracted in S310 is searched from the identification information 45a in the subscriber information DB 45. If the telephone number is not in the identification information 45a (in the case of No in S320), the process returns to S300. If the telephone number is in the identification information 45a (Yes in S320), the process proceeds to S325.

  In S325, the telephone number of the call destination of the calling signal is searched from the monitoring information 45c, and if the corresponding telephone number is not in the monitoring information 45c (No in S325), the process returns to S300 and exit / exit notification processing. repeat. Conversely, if the corresponding telephone number is in the monitoring information 45c (Yes in S325), the process proceeds to S330.

In S330, the position of the base station 15 that has received the call signal from the mobile phone terminal 10 is specified, and the process proceeds to S335 in FIG.
In S335, based on the telephone number of the mobile phone terminal 10, a contact is searched and extracted from the contact information 45d. If there is no corresponding contact (No in S335), the process returns to S300 and the book is issued. Repeat the withdrawal process. Conversely, if there is a corresponding contact address (Yes in S335), the process proceeds to S340.

  In S340, from the specified location of the base station 15, the nearest stop to the base station 15 is searched from the location information 45b in the transmittable / receivable area of the base station 15. If there is no corresponding stop as a result of the search (No in S340), the process proceeds to S380, and a message (from message information 45e indicating that the mobile phone terminal 10 is being called from a place other than the registered stop ( For example, “there is no corresponding stop” is acquired and set, and the process proceeds to S385. When setting a message, the message is data corresponding to the contact extracted in S335. That is, if the contact is a telephone number, the message is voice data, and if the contact is an e-mail address, the message is character data.

On the other hand, if there is a corresponding stop as a result of the search (Yes in S340), the process proceeds to S345.
In S345, the timer is counted up, the process proceeds to S350, the number of detections of the call signal transmitted from the mobile phone terminal 10 is counted at the same stop as the previous time, and the process proceeds to S355.

  In S355, a message to be transmitted to the contact is acquired and set from the message information 45e based on the stopover and the number of calls detected, and the process proceeds to S360. Here, the message acquired from the message information 45e is “I attended” if the call signal was detected for the first time, for example, if the stop was a cram school, and the call signal If the number of times of detection is the second time, “I have returned home”. When setting a message, the message is data corresponding to the contact extracted in S335. That is, if the contact is a telephone number, the message is voice data, and if the contact is an e-mail address, the message is character data.

In S360, the call signal detection count counted in S350 is added to the message acquired in S355, and the process proceeds to S365.
Next, in S365, it is determined whether or not the number of detections of the calling signal is within the specified number of times, and if within the specified number of times (Yes in S365), the process proceeds to S385, and if within the specified number of times. (No in S365), the process proceeds to S370.
