Description

  The present invention provides a portable navigation system capable of guiding routes using transportation, a portable navigation device such as a cellular phone and a PDA (Personal Digital Assistance) used in the portable navigation system, and communication with the portable navigation device. In particular, the present invention relates to a portable navigation system having balance storage means for storing a balance that can be used for settlement of transportation fare, a portable navigation device and a server used in the portable navigation system.

With the recent enhancement of functions of mobile terminals such as mobile phones, non-contact ICs can be incorporated into mobile phones and it is possible to automatically settle transportation fares such as railway fares. As a technique for incorporating the non-contact IC into a mobile phone, a technique described in Patent Document 1 below is conventionally known.
(Technique described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2003-0707019))
In Patent Document 1, an IC chip is built in a mobile phone, and every time a user passes an automatic ticket gate, boarding information or getting-off information is written and stored in an IC chip (non-contact IC), and the mobile phone is monthly. Describes a technique for making a payment by sending boarding information to a server.

However, in the technique described in Patent Document 1, it is necessary for the user to operate and transmit boarding information every month, which is troublesome for the user. In addition, if the user does not perform the operation mistakenly or does not bother, the boarding information is not transmitted, or if the user cancels the mobile phone contract on the way, the boarding information is obtained. There is a problem that cannot be settled.
Therefore, currently, a settlement method is adopted in which a payment amount (balance) is registered (charged) in advance in a contactless IC, and a fare is deducted from the balance each time it passes through an automatic ticket gate. As a non-contact IC technology using such a prepaid (payment in advance) settlement method, a non-contact IC called Suica (registered trademark) or ICOCA (registered trademark) is publicly known (for example, Japanese Patent Laid-Open No. Hei 11- 1601), this type of non-contact IC is expected to be mounted on mobile phones in the future.

Japanese Patent Laid-Open No. 2003-0707019 (paragraph numbers “0021” to “0028”, FIGS. 1 to 4)

However, in the prepaid payment method, the user has to register the balance in advance, and if the balance is insufficient when passing through the automatic ticket gate, the gate of the automatic ticket gate is closed. It's not pleasant that you suddenly close the gate due to insufficient balance, and it would be uncomfortable because it would be a loss of time for someone trying to pass in front of you to close the gate. . In particular, if the gate is closed during a rush hour (when crowded), the throughput (processing capacity) of the automatic ticket gate is reduced, causing congestion.
When a non-contact IC that adopts the prepaid payment method is built in a mobile phone, it may be possible to refer to the balance by application software that manages the balance, but it is cumbersome to check the balance, so the user It is hard to think of checking the balance frequently. Therefore, there is a problem that the gate of the automatic ticket gate is closed due to a shortage of funds.

In recent years, with the advancement of mobile navigation technology, it has become possible for a user to search for a route using a transportation facility from a departure place to a destination using a mobile phone. As such a technique, for example, there is a technique described in the specification of Japanese Patent Application No. 2003-369314 filed by the present applicant.
Although it is possible to check the fare of the transportation facility using the route searched by the route search, when confirming whether the fare is within the balance charged in the non-contact IC, the user once uses the navigation (route (Search) software must be closed and fare management software must be started. This is because a plurality of application software cannot be activated at a time due to the processing capability and storage area of the mobile phone. Therefore, in the prior art, in a state where the fare checked by the navigation software is stored by the user, the navigation software is terminated and the fare management software is started, and the user determines whether the fare is within the balance. There is a problem that it is necessary and user-friendliness is bad.

In view of the above-described circumstances, the present invention has a first technical problem of reducing the closing of the gate of an automatic ticket gate due to a shortage of balance.
Moreover, this invention makes it a 2nd technical subject to make easy confirmation whether the fare of a transportation system is less than a balance.

  Next, the present invention that has solved the above problems will be described.

(Operation of Example 1)
In the portable navigation system S according to the first embodiment having the above-described configuration, when the user wants to know the service area that can be reached within the balance stored in the contactless IC from the departure station, the user operates the cellular phone 1 to depart. In the station name input image (see FIG. 6), a departure station name is input or selected from the searched stations, and an “OK” icon 43 is input. When “OK” is selected, service area search data such as departure station, balance, commuter pass section, and the like are transmitted to the mobile navigation data distribution server 7. The mobile navigation data distribution server 7 that has received the service area search data searches for the service area from the departure station (see service area 56 of FIG. 12) in ST51 of FIG.

Next, when there is a commuter pass section, the commuter pass section can be moved free of charge, so a service area search is performed in consideration of the commuter pass section. If the departure station is outside the commuter pass section, it is determined in ST55 to ST56 whether the commuter pass section can be reached within the balance. If the commuter pass section can be reached, the fare to the commuter pass section is deducted from the balance in ST57, and the remaining balance is the service area from the commuter endpoint or branch point (service areas 57, 58, 59, 60 in FIG. 12). Search) (see ST58 to ST67).
When the departure station is in the commuter pass section, ST58 to ST67 search for a service area from a regular end point or branch point (see service areas 57, 58, 59, and 60 in FIG. 12) (see ST58 to ST67). ).
If there are service areas 57 to 60 from the regular end points or branch points, in ST67, the logical sum of the service areas 56 and 57 to 60 from the start point is taken, and the station farthest from the start station, that is, The station closest to the terminal station is the destination station. At this time, when the terminal station is a service area station, the service area station is “all stations” as shown in FIG.
In the service area search according to the first embodiment, the search for the service area station is performed both in the case of one way (ST40) and in the case of a round trip (ST42).

  When the search for the service area station in the mobile navigation data distribution server 7 is completed, the service area search result is transmitted to the mobile phone 1, and the mobile phone 1 that has received the service area search result image (see FIG. 8). Is displayed. Therefore, in the mobile phone 1 according to the first embodiment, the user can easily check the reachable station that can be reached one-way or round-trip with the balance. Further, by referring to the service area search result image, the user can also confirm that the destination he / she wants to go is not in the service area, and thus can recognize a shortage of balance. The balance can be easily charged by selecting the “charge” icon 33 in the main image. Therefore, when passing through the automatic ticket gate 10 at the destination station, it is possible to reduce the situation where the gate of the automatic ticket gate 10 is closed due to insufficient balance. As a result, it can be reduced that the gate is closed and the ticket gate is congested. It can also contribute to the promotion of the use of payment methods using contactless ICs.
