Description

  The present invention relates to a portable terminal having an electronic money function and a route guidance function, and more particularly to a portable terminal and a portable terminal control method for managing the balance of electronic money while performing route guidance.

  Some mobile phones are equipped with an electronic money function using a non-contact IC card from the viewpoint of carrying around and can perform payment processing simply by bringing the mobile phone close to a reading device when paying a fee. In addition to a cashless payment function, a mobile phone that integrates a credit card, a store membership card, a point card, and the like is also known. In addition, in order to make the boarding / exiting for transportation cashless, an IC card or the like that can pass by simply contacting the card at an automatic ticket gate is also used.

On the other hand, some mobile phones and personal digital assistants (PDAs) have a navigation function that guides the user to the destination while displaying the route to the destination on the screen. In some cases, the route to the destination is guided by displaying the route in real time and notifying the route by voice or the like. There has also been proposed an apparatus for searching for a route corresponding to the balance of an IC card by linking an in-vehicle car navigation apparatus and an automatic fee collection system (ETC) (for example, see Patent Document 1). This is because the balance information is taken from the IC card inserted in the in-vehicle device when searching for the optimal route to the destination, and compared to the toll road usage fee in the optimal route, if the balance is low, the IC card is credited. Prompt guidance. In addition, when the deposit to the IC card is set, guidance is provided to the depositable facility, and when the deposit is not set, the optimum route search including the toll road that can be used within the range of the balance can be performed.

  Note that information exchange between the electronic money management server 7 and the electronic money unit 15 is such that only a specific number or the like is stored in the electronic money unit 15, and substantial calculation processing and management processing depend on the electronic money management server 7. And a method in which the electronic money unit 15 performs calculation processing and balance management processing and the substantial payment operation depends on the electronic money management server 7 can be applied. The method of performing all arithmetic processing and management processing by the electronic money management server 7 can reduce the load on the CPU 16 on the mobile terminal 1 side, but it is possible to manage electronic money via the base station 2 only by knowing the balance information. It is necessary to connect to the server 7 for communication. On the other hand, the method of processing in the electronic money unit 15 holds information necessary for processing in the mobile terminal 1, so that the frequency of communication with the electronic money management server 7 can be lowered. The load of becomes higher. Therefore, which method is to be applied may be selected as appropriate in accordance with the capabilities of the electronic money management server 7 and the portable terminal 1 to construct the system. Here, in order to simplify the explanation, the electronic money unit 15 will be described as applying a method in which the electronic money management unit 15 performs calculation processing and balance management processing and the substantial payment operation depends on the electronic money management server 7.

Next, with reference to FIG. 2 to FIG. 4, an operation for guiding the route to the destination while managing the balance of electronic money will be described. First, the user operates the operation unit 13 of the mobile terminal 1 to activate a route guidance (navigation function) application. Then, the user sets and inputs his / her destination from the operation unit 13. The destination here is a department store where shopping is performed for shopping purposes, or a station where a meeting is held when waiting at a station. In addition, the user inputs a budget amount necessary to achieve the purpose at the destination as necessary. For example, if the purpose is shopping, a budget for shopping at the destination is input in advance. In addition, the cost required to achieve a predetermined purpose at the destination can include a transportation cost to the destination.
A plurality of destinations may be set as waypoints. For example, the first destination (passage point) and the second destination (passage point) are set in order from the home as the departure point, and finally You may make it set home as a suitable destination.

  Next, when the destination is input, the CPU 16 transmits the current position information acquired by the position measurement unit 12 and the input destination information to the navigation database server 5 via the transmission / reception unit 11 ( Step S1). At this time, if there is a commuter pass that the user already owns for commuting or attending school, the section information of the commuter pass is also input and the time is prioritized during search or the fee is prioritized. Enter search conditions such as The navigation database server 5 searches the guide route so as to satisfy the search conditions based on the current position information, the destination information, and the section information of the commuter pass, and calculates a transportation cost necessary for movement. At this time, the navigation database server 5 determines whether or not there is a period of a regular ticket in the optimum route searched based on the current position information and the destination information. Calculate and calculate accurate transportation costs. Then, the navigation database server 5 transmits the guide route information and the transportation cost information obtained as a result of the search to the mobile terminal 1. CPU16 which received this guidance route information and transportation expense information via the transmission / reception part 11 displays these received information on the display part 14 (step S2).

  Next, the user selects and inputs from the operation unit 13 whether to manage the transportation cost only one way or to manage the transportation cost in a round trip. Here, the CPU 16 determines whether or not it is a one-way setting (step S3), and when the round trip setting is selected, the transportation cost is doubled (step S4), and the memory 19b together with the current position information. (Step S5). Subsequently, the CPU 16 reads the remaining amount of electronic money (hereinafter referred to as the balance) stored in the memory 19e, and determines whether or not the transportation cost is smaller than the balance (whether the balance is sufficient). (Step S6). As a result of this determination, if the balance is insufficient, the CPU 16 issues a notification (warning) indicating that the balance is insufficient using screen display, sound generation, light emission, vibration generation, etc. (step S7), and electronic money Transition to the deposit mode. Here, the user deposits electronic money as necessary. Then, the CPU 16 determines whether or not the deposit has been made by confirming the deposit state in the memory 19e (step S8), and if there is a deposit, the process proceeds to step S6.

  On the other hand, if no deposit has been made, it is determined whether or not there is more balance than the minimum transportation cost (step S9). The term “minimum transportation cost” here refers to the minimum amount that can be used without any trouble for entering or exiting the latest transportation, and is, for example, the initial fare amount. If the result of this determination is that there is no remaining amount that does not interfere with payment of the nearest transportation (there is no remaining amount that can be paid for the first fare), the mode shifts to skip mode. The skip mode here is a mode that takes into account the case where there is no facility for depositing money. If the skip is rejected, the CPU 16 issues a notification (warning) indicating that there is not enough remaining money (step S7) and waits until the money is deposited. On the other hand, when the setting to skip is made, the fact that the mode has been shifted to the skip mode is stored in the memory 19b (step S10). Then, the CPU 16 guides the user to the destination based on the guidance route information while displaying the movement route to the destination including the walking route and transfer of transportation on the display unit 14 (step S11). FIG. 10A shows an example of a navigation screen when walking, and FIG. 10B shows an example of a navigation screen when using transportation.

  Next, the CPU 16 determines whether there is no payment for shopping at the destination (step S12). If payment for shopping occurs, the CPU 16 sets an amount that does not hinder payment for the latest transportation and a budget for shopping. It is determined whether or not the total value is smaller than the balance (step S13). If the result of this determination is that there are more balances, the CPU 16 instructs the electronic money unit 15 to settle the shopping. In response to this, the electronic money unit 15 executes a payment process, updates the balance stored in the memory 19e (step S14), and continues the route guidance (step S11).

  On the other hand, when the amount of payment is insufficient, a notification (warning) is issued indicating that the remaining amount is insufficient (step S15). Then, the CPU 16 determines whether or not to use the electronic money based on whether or not an operation of a payment instruction using the electronic money has been performed from the operation unit 13 (step S16). When payment is completed, etc., payment by electronic money is stopped (step S17), and route guidance is continued (step S11). When an instruction for payment by electronic money is given, the CPU 16 displays a message prompting for payment on the display unit 14. When the user sees this display and deposits electronic money, the balance stored in the memory 19e is updated (step S18). When the payment is confirmed, the CPU 16 determines again whether there is an insufficient amount of payment and the amount of shopping that does not hinder the payment of the latest transportation (step S19). If the remaining amount is still insufficient, the CPU 16 again A notification (warning) is issued (step S15).

  On the other hand, when the balance becomes a payable amount, the CPU 16 instructs the electronic money unit 15 to make a payment for shopping. In response to this, the electronic money unit 15 executes a payment process to update the balance stored in the memory 19e (step S20). If the information indicating that the memory 19b has shifted to the skip mode is stored in the memory 19b, the CPU 16 deletes this information (step S21) and continues the route guidance (step S11).

  Next, when it is determined in step S12 that there is no shopping, the CPU 16 determines whether or not it has arrived at a position where the transportation expense settlement should be made based on the position information of the terminal output by the position measuring unit 12. Is determined (step S22). As a result of this determination, if the transportation cost settlement position has not been reached, the process proceeds to step S6. On the other hand, when it has reached the position where payment for transportation expenses should be made, the CPU 16 determines whether or not it is in the skip mode (step S23). ) (Step S24) to prompt for payment. Here, when the user deposits electronic money, the balance stored in the memory 19e is updated (step S25). Then, the CPU 16 determines whether or not the balance has become an amount that does not hinder the latest transportation cost settlement (step S26), and if it is still insufficient, issues a notification (warning) again (step S24). When an amount that does not hinder the latest transportation expense settlement is deposited, the CPU 16 instructs the electronic money unit 15 to settle the shopping. In response to this, the electronic money unit 15 executes a payment process to update the balance stored in the memory 19e (step S27).

  Next, the CPU 16 determines whether or not the transportation expense settlement position is the final payment position with respect to the destination (step S28). If it is not the final payment position, the process proceeds to step S6. On the other hand, when it is the final payment position, the CPU 16 refers to the memory 19b and determines whether or not the one-way setting is selected when the destination is set (step S29). If the one-way setting is selected as a result of the determination, the electronic money unit 15 is instructed to end the balance management (step S30), and guidance is performed until the destination is reached (steps S31 and S32). On the other hand, when the round trip setting is selected, the CPU 16 performs guidance until the destination is reached (steps S33 and S34), and ends the route guidance process when the destination is reached (step S35).

  Next, the CPU 16 determines whether or not there is a payment for shopping (step S36), and when payment for shopping occurs, a value obtained by adding the amount that does not hinder the payment of the latest transportation and the amount of the shopping budget. It is determined whether or not it is smaller than the balance (step S37). If the result of this determination is that there are more balances, the CPU 16 instructs the electronic money unit 15 to settle the shopping. In response to this, the electronic money unit 15 executes the payment process, updates the balance stored in the memory 19e (step S38), and repeats the payment process until the shopping is completed.

  On the other hand, when the amount of payment is insufficient, a notification (warning) is issued indicating that the remaining amount is insufficient (step S39). Then, the CPU 16 determines whether or not to use electronic money based on whether or not a payment instruction operation using electronic money has been performed from the operation unit 13 (step S40). As a result of the determination, if payment is to be completed with cash or the like without payment with electronic money, the payment with electronic money is stopped (step S41). When an instruction for payment with electronic money is given, CPU 16 A message prompting the deposit is displayed on the display unit 14. By viewing this display and the user depositing electronic money, the balance stored in the memory 19e is updated (step S42). When the payment is confirmed, the CPU 16 determines again whether there is no shortage in the amount of payment and purchase amount that does not hinder the payment of the latest transportation (step S43). A notification (warning) is issued (step S39).

  On the other hand, when the balance becomes a payable amount, the CPU 16 instructs the electronic money unit 15 to make a payment for shopping. In response to this, the electronic money unit 15 executes a payment process and updates the balance stored in the memory 19e (step S44). Subsequently, when it is determined in step S36 that there is no shopping, the CPU 16 determines whether or not it has arrived at the position where the transportation expense settlement should be made based on the position information of the terminal output by the position measuring unit 12. Is determined (step S45). As a result of the determination, if the transportation cost settlement position has not been reached, the process proceeds to step S36. On the other hand, when it has reached the position where payment for transportation expenses should be made, the CPU 16 determines whether or not there is any trouble in payment in the nearest transportation (step S46). If the balance is insufficient, payment is made. Since it is not possible, the CPU 16 issues a warning (warning) (step S47) and prompts for payment. Here, when the user deposits electronic money, the balance stored in the memory 19e is updated (step S48). Then, the CPU 16 determines whether or not the balance has become an amount that does not hinder the latest transportation expense settlement (step S49), and if it is still insufficient, issues a notification (warning) again (step S47). When an amount that does not hinder the latest transportation expense settlement is deposited, the CPU 16 instructs the electronic money unit 15 to settle the shopping. In response to this, the electronic money unit 15 executes a payment process to update the balance stored in the memory 19e (step S50).

  Next, the CPU 16 matches the position information of the own terminal output from the position measuring unit 12 with the position information of the own terminal stored in the memory 19b at the start of route guidance, or starts route guidance. Then, it is determined whether or not the user is at the place where the transportation expenses are first settled (step S51). If it is determined that the user is not at that position, the process proceeds to step S36. On the other hand, when the vehicle reaches that position, no further payment is made for transportation, so the CPU 16 outputs an instruction to end the balance management to the electronic money unit 15 (step S52), and the process is terminated. To do.

  As described above, since the route guidance process and the electronic money process are linked together and the route search is performed by the route guidance process, the transportation cost is calculated, and it is determined whether or not the electronic money process can be settled. When the balance of money is insufficient, it is possible to display a message for prompting the deposit. In addition, when the regular route section owned by the user is included in the search route, it is possible to calculate the necessary transportation cost by subtracting the transportation cost of this section, so the optimal route Guidance can be performed. In addition, when it is determined that the necessary transportation expenses are insufficient due to purchase of a product or the like at a store in the middle of the guidance route, a notification (warning) that prompts payment can be performed.

  Further, when the user forgets to deposit, a notification (warning) that prompts the user that the amount of deposit is insufficient at the place of boarding or getting off can be performed based on the position information of the terminal. In addition, if you move in a way that does not use electronic money such as cash payment during route guidance, you can re-search the route or make the amount that you did not make electronic payment out of transportation costs management, The usage amount can be increased. Further, when the round trip setting is performed in the route guidance, since the management of the electronic money is canceled by passing through the vicinity of the first settlement position from the time of the route guidance setting, it is possible to prevent the lack of transportation costs.

<Second Embodiment>
Next, with reference to FIG. 5, the operation | movement which performs route guidance and balance management based on the information at the time of restaurant reservation is demonstrated. First, the user operates the operation unit 13 to activate an application for restaurant reservation. In response to this, the CPU 16 connects to the restaurant database server 6, reads the restaurant information, and displays it on the display unit 14. The user selects a desired restaurant from the displayed restaurants (step S61) and sets a reservation time, the number of people, and the like (step S62). Then, CPU16 acquires the positional information on the own terminal output from the position measurement part 12 (step S63), performs a route search from the positional information on the selected restaurant, and the positional information on the own terminal (step S64), Along with calculating the amount of transportation expenses necessary to travel to the restaurant, it is determined whether or not it is in time for the reserved time (step S65). As a result of this determination, if it is determined that it is not in time, the CPU 16 displays a notification (warning) indicating that it is not in time on the display unit 14 and displays a message prompting reselection (step S66), and proceeds to step S61.

  Next, when it is determined that it is in time, the CPU 16 transmits a restaurant reservation confirmation request to the restaurant database server 6. In response to this, the restaurant database server 6 refers to the reservation status information stored in the internal database to determine whether or not the reservation is possible. If the reservation is possible, the restaurant database server 6 performs the reservation process. The result is returned to the mobile terminal 1. If the reservation cannot be made, the mobile terminal 1 is informed that the reservation cannot be made. CPU16 which received this reply determines whether it was able to make a reservation based on this reply content (step S67). If the result of this determination is that reservation is not possible, the CPU 16 displays on the display unit 14 that reservation is not possible, and displays to prompt reselection (step S68), and proceeds to step S61. On the other hand, when the reservation is made, the CPU 16 obtains information on the fee or the approximate fee according to the setting from the restaurant database server 6 (step S69). Then, the CPU 16 adds the approximate fee of the obtained restaurant and the transportation cost, stores information such as a necessary budget, location information, and reservation date and time in the memory 19d, and performs route guidance. At this time, the CPU 16 performs route guidance in time for the restaurant reservation time.

  If the location of the terminal is acquired when the application is started and priority is given to the selected restaurant, the reservation time may not be set in time. In addition, if priority is given to the reservation time, a restaurant that is not in time may be excluded from selection candidates.

  In this way, when a restaurant is reserved using the mobile terminal 1, an estimated budget for this store is estimated, and this estimated budget is incorporated into the balance management of electronic money on the day of the reservation, so that the reservation time is not delayed. Since the route is guided to the store, it is possible to perform the optimum route guidance while managing the balance.

<Third Embodiment>
Next, with reference to FIG. 6, description will be given of an operation for reserving a ticket before the concert day and performing route guidance and balance management based on this reservation information. First, the user operates the operation unit 13 to activate an application for ticket reservation. In response to this, the CPU 16 connects to the ticket management server 4, reads the concert information, and displays it on the display unit 14. The user selects a desired concert from the displayed concerts (step S81), and determines the type of ticket, the number of purchased tickets, and the like (step S82). In response to this, the CPU 16 transmits a ticket reservation confirmation request to the ticket management server 4. In response to this, the ticket management server 4 refers to the reservation status information stored in the internal database to determine whether or not the reservation is possible, and performs reservation processing if reservation is possible. The result is returned to the mobile terminal 1. If the reservation cannot be made, the mobile terminal 1 is informed that the reservation cannot be made. CPU16 which received this reply determines whether it was possible to make a reservation based on this reply content (step S83). As a result of this determination, if the reservation cannot be made, the CPU 16 displays on the display unit 14 that the reservation is not possible, and displays a message on the display unit 14 asking whether or not to cancel the reservation. Here, if the user cancels the reservation, the user performs an operation for canceling the reservation, and if the user changes the date, time, seat, etc., performs the reselection operation. The CPU 16 determines whether or not to cancel the reservation (step S84), and if so, ends the process. If reselection is to be performed, the process proceeds to step S81, where selection is performed again.

  On the other hand, if the reservation can be made, the CPU 16 obtains information accompanying the ticket for which the reservation is confirmed from the ticket management server 4 and stores it in the memory 19c (step S85). The information acquired here includes the date of the event, the start time, the location information of the concert venue, electronic ticket data corresponding to the ticket, and the like. Then, the CPU 16 checks the date of the ticket data stored in the memory 19c when the date of the terminal itself is changed, and displays the concert date on the display unit 14 if it is a concert date (step S86). , S87).

  Next, the CPU 16 acquires the position information of the own terminal output from the position measuring unit 12 (step S88), and based on the concert hall position information stored in the memory 19c, sets the concert hall as the destination. The guided route search is performed (step S89). Then, the CPU 16 calculates the departure time by back-calculating based on the required time obtained as a result of the guidance route search and the concert start time stored in the memory 19c (step S90), and compares it with the clock of the terminal itself. It is then determined whether or not there is enough time (step S91). As a result, when there is no allowance, a notification (warning) is issued using sound, vibration, light, screen display, etc. (step S94), and the process proceeds to route guidance with balance management (step S96).

  On the other hand, if it is determined in step S91 that the time is sufficient, the CPU 16 determines whether there is a significant change in the position of the terminal based on the position information of the terminal output from the position measurement unit 12 (to the concert venue). Whether or not the movement of (1) has been started) is monitored (step S92). As a result of this monitoring, if there is no significant change in position, it is determined whether or not it is close to the departure time (step S93) and waits until the departure time is reached. If it is close to the departure time, the CPU 16 issues a notification (warning) and prompts to move (go out) (step S94). On the other hand, when the movement of the terminal itself is detected, the CPU 16 determines whether or not it matches the guidance route to the destination (step S95). If it matches the guidance route, it is assumed that the movement to the destination has been started as soon as possible, and the process proceeds to route guidance with balance management (step S96). If it is determined that the route does not match the guidance route, it is assumed that the terminal is moving to another place because there is enough time, and the position of the terminal is confirmed.

  As described above, when a concert ticket is reserved using the mobile terminal 1, it is possible to guide the route to the concert venue while managing the balance and / or time management so as not to be late for the start time on the day of the concert. . In addition, if the end time and return time are entered, the balance to the home and time management can be performed.

<Fourth Embodiment>
Next, an ambiguous transportation cost calculation method when returning home will be described with reference to FIG. First, the destination is set and the optimum route is searched (the same processing as step S1 shown in FIG. 2). At this time, the CPU 16 calculates the destination arrival time estimated from the optimum transportation cost and the current time together with the optimum route search. The CPU 16 determines whether or not a reciprocal setting has been made under the setting conditions (step S101), and if it is a one-way setting, no ambiguous setting is made (the process proceeds to step S6 shown in FIG. 2). On the other hand, when the reciprocal setting is made, the CPU 16 inquires of the user whether or not the ambiguous setting is performed. In response to this inquiry, the user operates the operation unit 13 to answer whether or not to perform ambiguous setting. The CPU 16 determines whether or not the ambiguous setting is performed based on the content of the answer (step S102). When the same route is selected for both the forward and return routes without performing the ambiguous setting, the step SS4 (FIG. 2). The balance is simply managed by doubling transportation costs.

  When performing the ambiguous setting, the CPU 16 calculates an ambiguous time obtained by multiplying the time required for the forward path by a preset constant (eg, 1.1) (step S103), and performs an ambiguous route search based on the ambiguous time. (Step S104). As a result of this route search, it is determined whether or not there are a plurality of ambiguous routes (step S105). If a plurality of search routes cannot be obtained, the ambiguous route becomes the optimum route. The CPU 16 determines whether or not a preset upper limit constant (for example, 2.0) has been reached (step S106), and if it has reached, there is no detour route that takes twice as much time as the optimal route ( It is assumed that there is only the same route in both directions, and the process proceeds to step S4.

  On the other hand, when the preset upper limit constant (for example, 2.0) has not been reached, the CPU 16 increases the constant by a number added to the preset constant (for example, 0.1 increments) ( Step S107), the ambiguous time is recalculated. When a plurality of ambiguous routes are obtained in step S105, the CPU 16 sets the highest transportation cost as the ambiguous transportation cost from the plurality of ambiguous routes (step S108). And CPU16 displays this ambiguous transportation expense on the display part 14, and makes it confirm that it manages with this money for a user (step S109). If there is no problem with the amount of money displayed on the display unit 14, the process proceeds to step S6 (FIG. 2). Here, when it seems that the difference between the transportation cost of the appropriate route and the ambiguous transportation cost is small (in the city center, the time and transportation cost are not directly proportional, so if the constant is small, the transportation cost will change less, If the meaning of the ambiguity is diminished, identity verification is required), and the process proceeds to step S106.

  In this way, in round trip traffic management, the route is the shortest and best route, but the return is not always guaranteed to return on the same route, so multiply by a predetermined constant based on the shortest and best route time. By calculating the ambiguous time and managing the amount of the route with a high transportation cost calculated from the ambiguous time as the transportation cost, it is possible to return home on another route without making a payment in the middle. By applying such an ambiguous transportation cost, it is possible to prevent the occurrence of a problem that the transportation cost is insufficient and it is impossible to return even if the route is slightly different between the outbound route and the returning route.

<Fifth Embodiment>
Next, with reference to FIG. 8, a processing operation related to getting off on the way home route will be described. The setting conditions such as the destination have already been input, and in a state where route guidance or transportation cost management is performed, the position measuring unit 12 outputs whether the process has shifted to step S111 and has reached the entrance of the transportation facility. When the determination is made based on the position information and the entrance (the ticket gate) is reached, the CPU 16 instructs the electronic money unit 15 to perform a settlement process. In response, the electronic money unit 15 settles the amount that can be entered (step S112). Further, after settlement, it is determined whether or not the exit of the transportation facility determined by the route search has been reached (step S113), and when the exit is reached, the exit settlement is performed to settle the transportation fare (step S119). . In this case, payment of the same amount as the management amount at the time of route search is made.

  On the other hand, if you get off the way when returning home, it is determined based on the position information output by the position measuring unit 12 that you got off at the station on the guidance route, and there is a shortage in transportation expenses until returning home with an unmanaged amount of money. It determines whether it does not occur (step S114), and if it does not run short, exit settlement is performed (step S119). On the other hand, if the amount is insufficient, the CPU 16 issues a notification (warning) using sound, light, or the like (step S115) and displays a warning message on the display unit 14 (see FIG. 10C). And CPU16 confirms the will of payment (step S116), and when it has received money (step S118), it transfers to step S119 and performs exit payment. If the payment is rejected due to reasons such as the absence of cash, the stoppage on the way is prohibited and the return route is guided (step S117).

  In this way, if you get off at the time of returning home, if you detect that you are about to get off at a station on the way home, based on the location measurement information, you can re-enter and get on the train before making the exit settlement at the ticket gate Judgment is made whether there is a balance remaining that can be paid, and if it is insufficient, it will prompt the deposit, and if it is not possible to pay, do not make payments other than the exit of the settlement position set in the route search Therefore, it is possible to prevent the transportation expenses from becoming insufficient and being unable to return.

  As described above, in a portable terminal equipped with an electronic money function and a route guidance function, when a destination is set, the optimal route to the destination is guided, and the electronic money is stored so that the necessary balance as transportation expenses remains. Since the management is performed, it is possible to prevent the occurrence of a situation in which it is difficult to move even if payment is made to achieve a predetermined purpose at the destination, resulting in a shortage of transportation expenses.
