Be composed.

FIG. 10 shows an owner check process executed on the memory card. This process is called from a business process such as a ticket issuing process (FIG. 10) and a ticket passing process (FIG. 12), which will be described later, and checks whether the memory card is correctly inserted into the memory card owner's mobile phone. Do. Block 102 is a determination process for taking the rescue device by the station worker's PDA 6 when the battery of the mobile phone runs out or breaks down. The PDA 6 of the station staff has the owner ID of the privilege code, and can always pass the owner check process with “normal return”.

Hereinafter, the processing flow of FIG. 10 will be described. First, in step 101, the mobile phone owner ID stored in the mobile phone nonvolatile memory is fetched.

In step 101, information on the electronic ticket (designated ticket) may be transmitted in addition to the mobile phone owner ID. In this case, this information includes the boarding and disembarking stations,
The boarding train and entrance time may be included.

Next, in step 102, it is determined whether or not the mobile phone owner ID captured in step 101 is a privilege code based on the data stored in the server 3. Further, whether or not the code is a privilege code may be determined based on data stored in the PDA 6. Next, when it is determined in step 102 that the code is a privilege code, the process proceeds to step 103.

In step 103, it is checked whether the certificate in the memory card is genuine. For example, the authentication is performed by transmitting the certificate to the server 3 via the network 10. If it is determined that the certificate is correct, the process proceeds to step 104.

In step 104, it is compared whether the mobile phone owner ID captured in step 101 matches the mobile phone owner ID stored in the memory card.

If a negative determination is made in steps 102 to 104, the process proceeds to step 106 as an error.

FIG. 11 shows a process of issuing a designated ticket from the server 3, and shows an exchange between the server 3 and the mobile phone 1. Here, the purchased designated ticket is downloaded to a memory card.

Here, the processing flow of FIG. 11 will be described in detail. This flow will be described by taking an example of an electronic ticket issuing process including a designated ticket.

First, in step 201, the mobile phone in which the user (user) has mounted the memory card activates an electronic ticket issuing menu. The activation trigger may be the insertion of a memory card or may be activated in response to an input from a user. And the mobile phone 1
A request for issuing an electronic ticket is transmitted to the server 3.

Next, in step 202, the server 3
Then, the electronic ticket issuing program is started in response to the ticket issuing request. Then, the server 3 provides the mobile phone 1 with:
The electronic ticket issuing program is notified that it has been started.

Next, in step 203, the mobile phone 1 sends the member I to the server 3
Send D and password.

Next, in step 204, the server 3
Authenticates the transmitted member ID and password. If it is authenticated, the input menu is presented to the mobile phone 1 according to the electronic ticket issuing program started in step 202. The menu may be presented for input only if the mobile phone 1 allows the user to input information for purchasing an electronic ticket, and the menu screen may not be displayed.

Next, at step 205, the mobile phone 1 receives from the user an input of the train no, the boarding station, and the getting off station, which is information for specifying the train that the user wants to board.
The train no has only to be able to specify the train, and includes the train name. Then, the mobile phone 1 transmits the input information to the server 3.

Next, in step 206, the server 3
Confirms whether there is a vacant seat in the train corresponding to the transmitted information. This confirmation may be performed by the same processing as the reservation system currently implemented by the railway company.

When there is a vacant seat, the server 3 presents information relating to the vacant seat and confirmation guidance to the mobile phone 1. For example, the information related to vacant seats includes information for specifying a train, the number of vacant seats, a seat number, a position in a train, a non-smoking smoking car, a fee, and the like. In addition, the confirmation guidance may be presented in such a manner that the mobile phone 1 can accept the reservation for the vacant seat indicated by the information on the vacant seat presented from the user, and does not need to display the menu screen.

Next, in step 207, the mobile phone 1 accepts an input indicating the user's intention to purchase the vacant seat presented through the confirmation guidance screen. That is, the designation of the purchase menu is accepted.

Next, in step 209, the mobile phone 1 takes in the mobile phone owner ID from the memory card.

Next, in step 210, the mobile phone 1 executes an owner check process shown in FIG. The details are as described above.

Next, in step 211, if an error is detected in step 210, the processing is interrupted, and the server 3 is notified of that fact. If normal, the memory card ID, which is the mobile phone owner ID stored in the memory card, is stored in the server 3
Notify.

Next, in step 212, the server 3 searches the member DB having the member record shown in FIG. 9 for information corresponding to the transmitted memory card ID.
If the search is not performed, the processing is stopped as an error.

When the search is performed, the processing necessary for the settlement is executed using the credit no included in the member record of the search result. That is, a settlement request including the credit no is notified to the computer of the credit company. Here, if a credit confirmation or the like is obtained, an electronic ticket issuing process is executed. That is, in step 207, a ticket is issued based on the information on the vacant seat input via the mobile phone 1. That is, create an electronic certificate for the electronic ticket,
Send to mobile phone 1.

Next, in step 213, the portable telephone 1 stores the transmitted electronic certificate in a memory card and treats it as a ticket.

Although the present processing flow is directed to the designated seat, it can be applied to a free seat. That is, in step 205, an input indicating that the user is in a free seat is received from the user. Then, in step 206, the server 3
Confirms whether the train is present (the confirmation may be omitted), and presents confirmation guidance including information required for purchasing a free seat such as a fare.

Next, the exchange between the portable telephone and the automatic ticket gate, which is the processing of passing the ticket gate, will be described with reference to FIG.

First, in step 301, a memory card storing an electronic ticket is attached to the mobile phone 1. In addition, the mobile phone 1 is used by an automatic ticket gate 4 by a user.
Is touched at the leader position. It should be noted that the touch on the reader position is only required if the automatic ticket gate 4 and the mobile phone 1 have a predetermined positional relationship. For example, the user may carry the mobile phone 1 and pass through the automatic ticket gate 4.

Next, in step 302, the automatic ticket gate 4 detects that the mobile phone 1 has been touched, and requests the mobile phone 1 for a memory card ID.

Next, in step 303, the memory card inserted into the mobile phone 1 requests the mobile phone non-volatile memory for the mobile phone owner ID.

Next, the mobile phone 1 notifies the memory card of the requested mobile phone owner ID.

Next, the memory card receives the notified mobile phone owner ID, and executes steps 305 and 306.
, An owner check process shown in FIG. 10 is executed.

Next, in step 307, if the result of the owner check process indicates that there is an error, the portable telephone 1 transmits a message to that effect to the automatic ticket gate 4. If the status is normal, the memory card ID is transmitted to the automatic ticket gate 4.

Next, at step 310, when the automatic ticket gate 4 receives the transmission indicating the error from the mobile phone 1, the automatic ticket gate 4 closes the ticket gate, displays a predetermined light, etc.
Execute control to prohibit passage. Also, the memory card I
When D is received, the memory card ID table is searched using the received memory card ID. As a result of the search, if the information corresponding to the memory card ID table is not stored, control is performed to restrict passage through the automatic ticket gate 4. Note that the memory card ID table may be stored in the automatic ticket gate 4 or may be stored in the server 3.

In step 311, the mobile phone 1 transmits the electronic ticket stored in the memory card to the automatic ticket gate 4. The electronic ticket may be the electronic certificate stored in step 213 of FIG. 11, or may transmit information that uniquely identifies the electronic ticket or the electronic certificate. Further, the electronic ticket includes information indicating the contents of the service that can be received with the present ticket.
For example, a train no, a boarding / alighting station, a boardable date and time, and the like are included.

If the memory card ID transmitted in step 310 is found, in step 308, the automatic ticket gate 4 determines whether or not it is possible to pass through the automatic ticket gate based on the transmitted information. For example, when the electronic ticket is transmitted, it is determined whether or not the electronic ticket corresponds to the contents of the service indicated by the transmitted electronic ticket. When the identification information is transmitted, the information about the electronic ticket indicated by the transmitted identification information is searched from the automatic ticket gate 4 or the server 3 and a determination is made based on the retrieved information.

It should be noted that whether or not the service is adapted to the contents of the service depends on whether the station is a section where the station can be got off, whether the electronic certificate (electronic ticket) is genuine, or whether the current time is outside the validity period. included. First, it is determined whether or not the station is a drop-off possible section by comparing the route information including the information of the station which the automatic ticket gate 4 or the server 3 has with the drop-off possible section indicated by the electronic ticket. The same applies to other conditions. Note that whether the current time is outside the validity period
The determination may be made using the train timetable shown in FIG.

Here, when it is determined that the service is not adapted to the service content, the self-propelled ticket gate 4 executes control for restricting the passage of the user. Also, when it is determined that it is adapted, the state is set so that it can pass. Making it passable includes leaving the gate open.

As a result, as shown in step 309, the user can pass through the automatic ticket gate 4.

Next, the electronic ticket referring process shown in FIG. 13 will be described. The reference process can be used in an in-house ticket check when the user checks the content.

First, in step 401, the mobile phone 1 takes out the mobile phone owner ID stored in the mobile phone nonvolatile memory. Alternatively, the PDA 6 accepts the input of the mobile phone owner ID.

Next, the memory card attached to the mobile phone 1 or the PDA 6 executes an owner check process shown in FIG. As a result, if it is determined in step 403 that an error has occurred, the fact is notified to the mobile phone 1 or the PDA 6
Output to If it is determined to be normal, step 4
04, the information about the electronic ticket (electronic certificate) stored in the memory card is stored in the mobile phone 1 or the PD.
A6 outputs.

Next, a description will be given of the processing of the oversleeping prevention service provided to the passengers of the train shown in FIG. This service is provided on the mobile phone 1 periodically (for example, 10
The processing flow of the timer process started in the (minute period) will be described. Passengers subscribing to this service can be automatically woken up by a cell phone alarm, bell, etc. before the disembarkation time without having to set the alarm clock in the train.

First, in step 501, the mobile phone 1 detects whether a memory card is mounted (mounted) on the mobile phone 1. If a memory card is inserted, the process proceeds to step 502.

Next, in steps 502 to 503,
The owner check process shown in FIG. 10 is executed. If it is determined in step 504 that the owner check processing result is normal, the process proceeds to step 505.

In step 505, the mobile phone 1
It is detected whether an electronic ticket (electronic certificate) is stored in the inserted memory card. If the electronic ticket is stored, the process proceeds to step 506.

In step 506, the mobile phone 1
An alarm is set when a condition including a preset time of the getting-off time is satisfied. Thereby, the mobile phone 1 issues an alarm (or vibration) when the set condition is satisfied. Step 5
If a negative determination is made in 01, 504, and 505, the process ends without setting an alarm.

Next, the present process will be described again using an example. The first example will be described on the premise that the electronic ticket is a commuter pass. First, the processing is started with the trigger that the user enters from the automatic ticket gate 4 as a trigger. For example, in step 308 of FIG. 12, the automatic ticket gate determines that the ticket is a valid electronic ticket, transmits the determination result to the mobile phone 1, and starts the process when the mobile phone 1 receives the determination result.

After being activated, steps 501 to 505 are executed. Then, in step 506, the time to be set is determined from the information of the boarding station and the getting off station indicated by the electronic ticket. That is, the travel time between the boarding station and the disembarking station is calculated by the same technology as the existing route search software, and an alarm is set after the travel time (for example, 10 minutes). In addition, the time to be set may include information indicating a boarding time in an electronic ticket which is a commuter pass, and may be the time indicated by this information. Note that the information of the getting off station may be taken from the train timetable shown in FIG.

Next, a second example will be described. The second example is a case where the electronic ticket includes a designated ticket. In this example, the activation may be started with the purchase of the electronic ticket as a trigger. In other words, the mobile phone 1 detects the reception of the electronic ticket in step 213 shown in FIG. In this case, the processing of step 506 may be executed by omitting steps 501 to 505.

In step 506, the time is set as a condition. First, the arrival time at the getting off station indicated by the electronic ticket stored in the memory card is detected. next,
A time based on the detected arrival time is calculated and set. The time based on the arrival time includes a time obtained by subtracting a fixed time (5 minutes) from the detected arrival time. Then, the mobile phone 1 generates an alarm or a vibration at a time based on the arrival time.

In step 506, a location including the nearest station may be set as a condition. For example, a drop-off station indicated by the electronic ticket is detected. Then, the detected getting-off station is set as a condition. Further, from the information processing device installed in the train, every time the vehicle reaches a stop station and a predetermined position, information indicating that fact is broadcast. Mobile phone 1
Receives this information, and generates an alarm when the stop station is the set-off station.

The information processing device installed on the train
The information may be transmitted to a mobile phone at which the stop station becomes the drop-off station. That is, the information processing device installed in the train transmits the telephone number (may be an e-mail address) of the mobile phone of the user who purchased the electronic ticket of the train from the server 3 and information on the electronic ticket including the getting off station. Receive. And
When a predetermined position is reached with the stop station, which is the drop-off station, a call is made to the corresponding telephone number or a mail is transmitted to the mail address indicating that the drop-off station is approaching. As a result, the mobile phone has the same effect as that of the call and the alarm. Therefore, in the mobile phone, it is possible to omit the setting of the condition and the generation of the alarm according to the condition.

The information processing device installed on the train
According to the operation schedule, a certain time before the arrival time at the stop station may be detected, and when the certain time comes before, the fact may be transmitted and broadcast. Further, similarly to the first example of the commuter pass, passing through an automatic ticket gate may be used as a trigger. Furthermore, when the mobile phone has a position detection function such as a GPS function,
An alarm may be activated by detecting that the vehicle has entered a certain distance from the getting off station. In addition, setting the condition as the position
It is also possible to apply to tickets other than designated tickets and commuter passes.

In the first embodiment, it is determined whether the memory card is correctly mounted on the owner's mobile phone by matching the memory card owner ID with the mobile phone owner ID. Second, the mobile phone may be focused on having a mobile phone ID (device number) that uniquely identifies the mobile phone, and the mobile phone may be used to determine whether the memory card is correctly mounted on the owner's mobile phone. . Specifically, in correspondence with the first embodiment, (1) the mobile phone ID of the mobile phone of the memory card owner is stored in the memory card 2. (If there are a plurality of mobile phones, the mobile phone IDs of a plurality of mobile phones to which a memory card may be attached are stored). (2) In the owner check process of FIG. 10, the mobile phone ID is fetched from the mobile phone, a match check with the mobile phone ID stored in the memory card 2 is performed, and if there is a match, the process returns normally. .
(3) Block 209 of the designated ticket issuing process in FIG. 11, blocks 303 and 304 of the ticket passing process in FIG. 12, FIG.
Block 402 of sleepover prevention service timer activation processing
Is the mobile phone I instead of the mobile phone owner ID
D will be used.

As another embodiment, the method of using the telephone number of the portable telephone in place of the portable telephone ID of the second embodiment, and the meaning of identifying the owner instead of the owner ID of the first embodiment are as follows. However, the use of an ID for identifying a memory card and a set of mobile phones to which the memory card is likely to be attached, or a password (character string) shared therewith is also equivalent to the present invention. It can be considered as a method.

[0078]

According to the present invention, an electronic ticket system capable of rescuing a battery of a mobile phone even in the event of battery exhaustion or failure has become possible. Further, in the present invention, the interface between the mobile phone and the memory card is a standard interface which is obtained by adding an antenna interface to the memory card interface. When processing equivalent to that of a memory card is incorporated in a mobile phone, there is also a remarkable effect that the development cost of the mobile phone is reduced as compared with the case where design work is performed for all models of the mobile phone.
