`PORTABLE TERMINAL DEVICE, CHARGING
`MANAGEMENT COMPONENT, AND
`PROGRAM FOR CONTROLLING PORTABLE
`TERMINAL
`
`TECHNICAL FIELD
`
`[0001] The present invention relates to a portable tenninal
`device, a charging management component, and a program
`for controlling a portable terminal capable ofprocessing elec-
`tronic money Via RFID (Radio Frequency Identification)
`communication.
`[0002] An RFID tag refers to an IC chip or resin card
`including a nonvolatile memory and a wireless communica-
`tion (RFID communication) function therein. Recently, as the
`RFID tag, an IC chip or card having a high security function
`or a CPU has been introduced.
`[0003]
`It is possible to exchange data for fee payment by
`using the RFID tag as a pre—paid card or electronic money
`while holding the RFID tag over a reading terminal. Recently,
`an attempt to use a mobile phone instead of a ticket or a wallet
`has been made with an RFID tag built in a mobile phone.
`[0004] Here. the “electronic money” refers to a monetary
`value represented in digital data and is used as a payment
`means for shopping without use ofa credit card or cash, or for
`an electronic connnercial transaction using the Intemet or the
`like.
`In the related art, mobile phones which handle elec-
`[0005]
`tronic money have been proposed.
`[0006]
`For example, it has been proposed an electronic
`money device which includes means for storing use purposes,
`an upper limit for each use purpose, a range of a money
`amount requires an authentication process, and the like, and
`means for storing authentication information, and which, in
`response to receiving the user selection of use purpose at the
`time of executing the payment process, determines whether a
`money amount is in an available range predetermined based
`on payment conditions and determines whether the money
`amount requires the authentication process. Accordingly, a
`flexible handling can be realized while putting the importance
`on convenience rather than security when a small amount of
`money is paid (for example, see Patent Document 1).
`[0007]
`Patent Document 1: JP-A-2005-55958
`
`
`
`DISCLOSURE OF INVENTION
`
`Problem to be Solved by Invention
`
`For example, in a mobile phone which handles elec-
`[0008]
`tronic money as shown in FIG. 5, a dedicated electronic
`money management 1C 20 for and a main control unit 30
`serving as a control center of the mobile phone are each
`configured by an independent CPU.
`[0009]
`In this configuration,
`the payment of electronic
`money input to a pool area (not shown) included in the elec-
`tronic money management IC 20 is processed only by the
`electronic money management IC without involving the main
`control unit 11.
`[0010] Charging infonnation as a basis ofpayment is wire-
`lessly transmitted via an antenna 50 from a reader/writer 40
`installed in a shop or station ticket gate.
`[0011] However,
`in the technique described in Patent
`Document 1, it is not sufficient to set an appropriate use limit
`(an upper limit of a use purpose) in response to the user’s
`need.
`
`It is complex to conduct detailed payment manage-
`[0012]
`ment while dividing use categories of electronic money into
`railroad—fare payment, shopping by cash in a shop, and the
`like.

`vided for each charging category such as a railroad commut-
`ing ticket, shopping by cash, or credit for a single pool area
`100A, An upper limit of use of each category may be prede-
`
`electronic money is
`the
`termined. Characteristically,
`decreased only from the payment area 1 00B when a payment
`process is executed.
`[0062] A plurality of pool areas may be provided for each
`electronic money management company. In this case, a pay—
`ment area for each charging category may be associated with
`each pool area. That is, the association is made so that elec—
`tronic money is not transferred from a plurality of pool areas
`to one payment area since the charging situation is separately
`managed for each management company.
`[0063] The interface unit 101 functions as an interface
`between the main control unit 11 and the RFID unit 10 (the
`charging control unit 102).
`[0064] The charging control unit 102 includes a CPU
`therein and has a function of executing the charging process
`for the charging storage tulit 100 based on charging informa-
`tion received by the wireless communication unit 103 to be
`described later.
`[0065]
`Specifically, when electronic money is received
`from the electronic money management device 4 (or a charge
`terminal (not shown)), the charging control unit 102 stores a
`received money amount in the pool area 100A of a corre-
`sponding management company of the charging storage unit
`100, and pays electronic money from the payment area 100B
`of a corresponding management company in the charging
`storage unit 100 based on charging information received from
`the reader/writer 5.
`[0066] As described later, the main control unit 11 is
`capable oftransferring a part ofelectronic money infomiation
`stored in the pool area 100A of the charging storage unit 100
`to the payment area 100B based on an operation of the opera-
`tion unit 13.
`[0067] The charging control unit 102 determines whether
`charging information received by the wireless communica-
`tion unit 103 is within the money amount stored in the pay-
`ment area 100B of the charging storage unit 100. When the
`money amount indicated by charging information is greater,
`the charging control unit 102 transmits charging disapproval
`information by the wireless communication unit 103 and
`notifies the main control unit 11 of the charging disapproval.
`[0068] The charging control unit 102 determines which one
`of the plurality of payment areas 100B money is paid from,
`based on information indicating a charging category and a
`charging management company included in the charging
`information received by the wireless communication unit
`103.
`[0069] The wireless communication unit 103 receives
`power supplied from the reader/writer 5, and performs wire—
`less communication between the mobile phone 1 and the
`reader/writer 5 via the RFID unit 10.
`[0070]
`In a state where communication by the RFID unit 10
`is available, the charging storage unit 100, the interface unit
`101, and the charging control unit 102 operate while receiving
`power supplied from a battery (not shown) included in the
`mobile phone 1.A wireless link is shown for commtmication,
`but a direct connection of a wired link or the like, not the
`wireless link, may be used,
`[0071] The main control tmit 11 entirely controls the over-
`all operation of the mobile phone 1.
`[0072] That is, the main control unit 11 controls the opera-
`tion ofthe RFID unit 10, the storage unit 12, the operation unit
`13, the notification unit 14, and the connnunication unit 15 so
`that various processes of the mobile phone 1 (audio commu-
`nication via a telephone switching network, the creation and

`
`transmission/reception of electronic mail, the control ofread-
`ing or the like ofWeb (World Wide Web) sites of the Internet,
`and the transfer of electronic money) are executed in an
`appropriate procedure in response to an operation of the
`operation unit 13.
`[0073] The main control unit 11 has a CPU (microproces—
`sor) to execute a process based on a program (an operating
`system. an application, or the like) stored in the storage unit
`12. The process is executed according to a procedure indi-
`cated in the program.
`[0074] That is. a process is executed by sequentially read-
`ing command codes from the operating system or the running
`application program stored in the storage unit 12. The appli-
`cation program stored in the storage unit 12 may be down-
`loaded from the conmiunication unit 15 Via the Internet.
`[0075] Here, when a request for transferring a part of the
`electronic money from a pool area 100A of the charging
`storage unit 100 of the RFID unit 10 to a payment area 100B
`is generated by the operation unit 13, the main control unit 1 1
`outputs a remaining value based on electronic money infor-
`mation stored in the pool area 100A of the charging storage
`unit 100 to the notification unit 14. A control operation is
`performed to decrease the money amount input by the opera—
`tion unit 13 within a displayed remaining value range from
`the pool area 100A of the charging storage unit 100 and to
`increase the money amount in the payment area 100B of the
`charging storage unit 100 by the decreased money amount.
`The electronic money may be transferred based 011 a request
`from a unit other than the operation unit 13. For example, a
`request for transferring a part of electronic money may be
`made by operating the reader/writer 5.
`[0076] When the charging disapproval is notified from the
`charging control unit 102, the main control unit 11 controls
`the notification unit 14 to notify the charging disapproval.
`[0077] The storage unit 12 stores various data to be used for
`a process in the main control unit 11. For example, the storage
`unit 12 stores an application program to be executed by the
`main control unit 11, address book data for managing per—
`sonal information such as a phone number of a communica—
`tion partner or an electronic mail address. transmission/re—
`ception history data of a phone call or mail, schedule data, an
`audio file for reproducing a ring tone or an alarm tone, various
`setting data, and temporary data for use in processing a pro-
`gram.
`For example, the above-described storage unit 12 is
`[0078]
`configured by a nonvolatile storage device (flash memory), a
`randomly accessible storage device (SRAM or DRAM). or
`the like.
`
`For example, the operation unit 13 has a plurality of
`[0079]
`keys to which various functions are assigned such as a power
`key, a call key. numeric keys, character keys, direction keys.
`an enter key, a send key, and the like. When the keys are
`operated by an operator, the operation unit 12 generates a
`signal corresponding to operation content and inputs the gen-
`erated signal as an instruction of the operator to the main
`control unit 1 l.
`
`for
`[0080] The notification unit 14 is configured by,
`example, a display device such as an LCD panel or an organic
`EL (Electro-Luminescence) panel. Here, an LCD module
`including the RAM 160 incorporated therein to store image
`data is used.
`
`[0081] The notification unit 14 displays an image corre-
`sponding to a video signal supplied from the main control unit
`11. Specifically, the image includes information regarding a
`
`money amount used by electronic money payment and an
`insufficient money amount as well as a phone number of a
`transmission source upon transmission, a phone number of a
`reception counterpart upon reception, a reception mail, or a
`transmission mail. An audio output by a speaker may be
`substituted therefor.
`[0082] The public communication unit 15 catches a plural—
`ity of communication systems, and, for example, performs
`wireless communication with the communication server 2 of
`the communication common carrier in accordance with a
`communication protocol such as CDMA 2000 1x (hereinaf-
`ter, referred to as 1x), BVDO, or a wireless LAN. A money
`receiving process or a transmission/reeeption process for
`charging information is executed with the electronic money
`management device 4 connected via the communication
`server 2 and the communication network 3 such as a WAN.
`[0083]
`FIG. 3 is a flowchart showing the operation of a
`payment area setting process of the portable terminal device
`according to an embodiment of the present invention. Here,
`the operation flow in each of the main control unit 11 and the
`charging control unit 102 and the relationship therebetween
`are shown.
`[0084] Hereinafter, the operation of the payment area set—
`ting process of the portable terminal device according to an
`embodiment of the present invention will be described with
`reference to the flowchart shown in FIG. 3.
`[0085] When electronic money is used, at first, each device
`authentication process between the main control unit 11 and
`the charging control unit 102 is executed (steps S301 and
`S311)
`“When the authentication has succeeded (step S302
`[0086]
`“Yes”), the main control unit 11 selects an payment area 100B
`allocated to the charging storage unit 100 to which electronic
`money is transferred (step S303). The main control unit 11
`notifies the charging control unit 102 ofthe selected payment
`area 100B via the interface unit 101, and the charging control
`unit 102 receiving the notification determines the payment
`area 100B in the charging storage area 100 (step S312).
`[0087]
`Subsequently, the charging control unit 102 deter-
`mines a pool area 100A from which electronic money can be
`transferred to the selected payment area 100B, and notifies
`the main control unit 11 of a remaining value ofthe pool area
`100A (step S313). The main control unit 11 receiving the
`notification displays the remaining value of the pool area
`100A, on the notification unit 14 (step S304).
`[0088] The user who has read the remaining value of the
`pool area 100A displayed on the notification unit 14 inputs a
`money amount to be transferred to the payment area 100B for
`each charging category prepared for a management company
`selected by operating the operation unit 13 (step S305).
`[0089]
`Subsequently, the main control unit 11 which has
`acquired the money amount input via the operation unit 13
`compares the input money amount with the pool remaining
`value (step S306). When it is confirmed that the input money
`amount is Within the pool remaining value (step S306 “Yes”),
`the main control unit 11 sends a notification (an input money
`amount setting notification) to the charging control unit 102
`so that the money amount input to the payment area 100B is
`set. Then, the payment area setting process by the main con-
`trol unit 11 ends (step S307).
`[0090]
`“When the input money amount exceeds the pool
`remaining value (step S306 “No”), the main control unit 11
`returns to step S304 (the process of displaying the remaining
`value of the pool area 100A).

`
`[0091] On the other hand, the charging control unit 102
`receives the input money amount setting notification from the
`main control unit 11, sets the money amount to the payment
`area 100B ofthe charging storage unit 100, and ends a setting
`process for the pa
