Description

  The present invention relates to a mobile phone, and more particularly to a mobile phone that can be used in a digital money system.

  The global Internet has become widespread, and the movement to conduct electronic transactions (EC) using this Internet has become full-scale. Generally, compensation has been conventionally paid by an electronic card.

  In (a) “Home banking system using an IC card”, for example, a Mondex system is known. In this method, payment is made with an IC card, but digital money can be replenished or transferred using a home phone.

Further, an IC card having a mobile phone function has been proposed (see, for example, Patent Document 1 and Patent Document 2).
(B) Patent Document 1 describes the technology relating to a post-payment type vending machine system using a mobile phone terminal, in which the name of the invention is called “vending machine system”.
(C) Patent Document 2 describes a technology in which the name of the invention is referred to as a “composite IC card” and a mobile phone function is added to one IC card.

Furthermore, there are the following cases in which digital information services are made possible by allowing the communication function of the mobile phone to perform data processing other than functions necessary for communication such as codecs.
(D) “Combination of notebook computer and mobile phone”
(E) "Combination of electronic notebook or PDA (Personal Digital 1 Assistant) and mobile phone"
However, in the usage modes (d) and (e), the mobile phone is only used as a data communication means.

  Here, as a mobile phone having data communication means, a known PHS (Personal Handy-phone System) will be described with reference to FIG. The PHS includes an antenna 1, a portable communication I / F 2, a modem 3, an audio codec DSP 4, a digital / analog converter 5, a microphone 6, a speaker 7, an LCD (Liquid Crystal Display) 8, a KEY, an LED (Light Emitting Diode) 10, It comprises an external connector 11, a memory 12, an MPU (Micro Processing Unit) 13, a protocol controller 14, and a panel I / F 16. The audio codec DSP 4 and the digital / analog converter 5 are collectively referred to as a codec 15.

  Next, main circuits will be described. The portable communication I / F 2 is a device for controlling the antenna 1 that receives radio waves from a remote place and for generating radio waves. The modem 3 is a device that converts data to be transmitted into a high-frequency signal and converts a received high-frequency signal into a baseband signal.

  The audio codec DSP4 is a circuit that digitally processes a digitized audio signal. The digital / analog converter 5 is a device that converts an audio signal into digital and converts it into received digitized audio signal analog. The memory 12 stores a telephone number and the like. FIG. 3 shows a telephone number book stored in the memory 12.

  The MPU 13 executes a control program as a mobile phone and an application program such as an address book. The protocol controller 14 is a device that determines a data path. For example, such a path is determined that data received by the antenna is transmitted to the outside through the external connector 11 or output to the speaker 7 through the codec 15.

  The codec 15 is a device that converts received digital audio into analog audio and outputs the analog audio to the speaker 7 or digitally converts analog audio input from the microphone 6. When transmitting voice from the PHS, the voice is detected by a microphone, and the other party's telephone is set via the digital / analog converter 5, voice codec circuit 4, modulator / demodulator 3, long-distance communication I / F 2 and antenna 1. Sent to.

  In addition, when data stored in the memory 12 is transmitted from the PHS, it is transmitted to the other communication terminal via the memory 12, the MPU 13, the protocol controller 14, the modulator / demodulator 3, the long-distance communication I / F 2 and the antenna 1. Sent. When transmitting external data by PHS, the data is transmitted to the partner data communication terminal via the external connector 11, protocol controller 14, modulator / demodulator 3, long-distance communication I / F 2, and antenna 1.

  Audio signals from other telephones are generated from the speaker 7 via the antenna 1, portable communication I / F 2, modulator / demodulator 3, audio codec DSP 4, and digital / analog converter 5. Data from other data communication terminals is output to the outside via the antenna 1, the portable communication I / F 2, the modem 3, the protocol controller 14, and the external connector 11.

Therefore, in terms of PHS, in the usage forms (d) and (e), data passes through the long-distance communication I / F 2, the modem 3, the protocol controller 14, and the data communication external connector (external connector) 11. It is only possible to transfer data with an external notebook computer, electronic notebook or PDA. Furthermore, the following are examples of conventional cases in which portable devices are used in combination.
(F) "Combination of GSM (Global System for Mobile Communications) and SIM (Subscriber Indentity Module Card)"
(G) “Combination of PDA and keyboard”
The GSM in the case of (f) is a cellular phone mainly used in Europe, and a card reader of a prepaid card called a SIM card is integrated with the main body. Thereby, it is possible to borrow another person's mobile phone and make a call like a public telephone.

As an example of (g), there is a combination of a 3Com Palm Pilot and a Fujitsu one-handed keyboard as an example of attaching a close-contact keyboard to a PDA.

  By the way, in the above (a) “home banking system using IC card”, there is a function to pay when shopping, but it is necessary to separately put money (digital cash) in the electronic card, which is complicated. For example, in the above-mentioned Mondex home banking system, a user needs to purchase a new telephone set with an interface with an electronic card and insert a digital cash. Furthermore, it becomes necessary to purchase a dedicated accessory.

  In addition, the electronic card does not have a voice communication function and cannot receive voice instructions. Moreover, the payment of the consideration in the invention described in Patent Document 1 is a post-payment method, and digital money cannot be distributed. In addition, the invention described in this publication does not have a voice communication function and is unusable.

  Further, in the postpay method, even if payment exceeds the payment capability, it cannot be confirmed. Therefore, payment beyond the payment capability cannot be prevented. The invention described in the above (c) Patent Document 2 shows the technology of a composite IC card that combines the function of an IC card and the function of a mobile phone. Since this publication does not have an encryption / decryption function that is essential for handling digital money, it cannot handle digital money. Also, it is unclear how to use it.

Therefore, in order to distribute digital money, the following problems are raised.
1 Easy access to digital money
2 Support by voice guidance to improve operability,
3 To enable immediate payment within the scope of deposit with a financial institution;
4 Take necessary security.

  Further, although the cellular phones in the above (d), (e) and PHS have a communication function, they do not have a function of receiving and paying money (digital cash). In order to receive and pay money, a function for storing data, a function for performing encryption during communication, a function for selecting data to be transferred, and the like are required. A general mobile phone lacks these functions.

  Furthermore, in order to realize an information communication service system (a system that provides services by transferring digital data via communication and processing the data) including mobile devices that can be used by "anytime, anywhere, anyone" It is necessary to place importance on portability, and it is required that the volume and weight do not exceed 1.5 times that of mobile phones that are widely spread. In that respect, the above (d), (e), and (g) are insufficient. In particular, notebook computers, electronic notebooks, and PDAs have their own displays and keyboards, so their portability is significantly worse than wallets that have been carried so far. In addition, a low price is also a necessary factor, and it is not acceptable at 1.5 times the price of the mobile phone, and the above (d), (e), and (g) are insufficient.

In addition, a data processing mechanism for receiving an information communication service and a memory mechanism for storing data are required first, and human I / F cooperation is required for cooperation between the service and humans. The memory mechanism of (f) above is not sufficient. That is, there are the following five points as problems in the terminal.
5 Volume and weight are small enough to place importance on portability,
6 Having both communication and information processing functions (corresponding to 2 above)
7 Human interface functions such as display function and speaker function can be used.
8 Low price.

  The present invention has been made in view of the above problems, and an object thereof is to provide a mobile phone that facilitates the spread of digital money.

  In view of the above problems, the present invention enables communication with a radio base station for using a public line network in a mobile phone capable of making a call via a public telephone line network used in a digital money system.

Next, embodiments of the present invention will be described with reference to the drawings. The present invention relates to a mobile device, a mobile terminal attachment, and a system using the mobile device, and the description will be given in the order of the mobile device, the system using the mobile device, and the mobile terminal attachment.
1. Mobile Device FIG. 2 is a configuration example of the mobile device of the present invention. Compared with the conventional PHS shown in FIG. 1, the configuration is different in that it relates to a general-purpose MPU 23 that can execute a program, a protocol controller 24, a memory 25, a cryptographic calculation dedicated arithmetic circuit 26, and a short-range communication device I / F 27 .

  An operating system (OS) is installed in the MPU 23, and the peripheral device is controlled by the MPU 23 and an application program mounted in the memory 25 is executed. The protocol controller 24 is a device that determines a data path. The memory 25 stores an application program, each user's name, address, owned digital cash (digital money data), digitized admission ticket, points given by the store at the time of payment, and the like. It is read out by the MPU 23, processed and output to the outside. FIG. 4 shows an example of the contents stored in the memory 28. In FIG. 4, application programs, personal attribute information, personal telephone books, registration data, service information, etc. for handling various services are stored.

  The cryptographic calculation dedicated arithmetic circuit 26 is a device used for encryption / decryption when handling data requiring high security such as application programs for digital money and point cards. Data stored in the memory is encrypted as necessary. The cryptographic calculation dedicated arithmetic circuit 26 may be configured using an encryption / decryption processor, and the encryption / decryption method may be changed by changing the software.

  The short-range communication device I / F 27 is a device for exchanging data between short-range devices, and an infrared device such as IrDA is used here. Communication with a financial institution (access to a computer of a financial institution, withdrawal of digital money, etc.) is performed via an antenna 1 as a normal mobile phone. Further, communication with the store terminal (payment of digital money, acquisition of points, etc.) is performed via the I / F 27 for short-range communication devices.

  The display means is not limited to the LCD, and other display means may be used as appropriate. Also, other display means may be used as appropriate as data input or output means. This mobile device is a terminal used in the following “2. System using mobile device”, and may be one in which the attachment described in “3. Attachment for mobile terminal” is attached to a mobile phone.

The method of using the portable device is described in “2. System using portable device” and “3. Attachment for portable terminal”.
2. System Using Mobile Device First, a digital money system that pays with a digital money for the price of goods or services will be described as an example of a system using a mobile device.

  FIG. 5 shows a configuration of the digital money system, and flowcharts in use are shown in FIGS. The digital money system includes a computer 30 of a financial institution, a radio base station 31, a portable device 32, and a store terminal 33 provided in the store 35. As the mobile device, a mobile device described in “1. Mobile device” or a terminal to which the mobile terminal attachment described in “3. Mobile terminal attachment” is added is used.

  A financial institution means not only a bank but an institution that handles money (for example, a credit union or the like). A store is a main body that sells services or goods, and includes vending machines. This system constitutes a network, and a public telephone network can be used as this network. When a public telephone network is used, the radio base station 31 is a radio base station of a public mobile communication network. The computer 30 and the portable device 32 of the financial institution can communicate by dialing a telephone number via the nearest radio base station 31 via the public mobile communication network. If necessary, this system owns a unique network composed of a computer 30, a wireless base station 31, a mobile device 32, and a store terminal 33 of a financial institution, and the wireless base station is installed as a part of the network. It may be provided.

  As described above, the mobile phone having the wallet function (the mobile device described in “1. Mobile device” and executing the digital money program) 32 has the functions of the conventional mobile phone. In addition to an encryption / decryption function, a memory having a capacity capable of storing a digital cache and various types of user data, and an infrared communication function capable of proximity communication are added.

  First, a user of the system (a customer as viewed from the store 35) carries the portable device 32. Then, the user deposits money in advance in the financial institution 34. When the user thinks that he / she needs to withdraw money or the computer 30 of the financial institution uses the mobile phone system (for example, when the digital cash becomes below a certain level), the user makes money by voice. When it is better to withdraw, the telephone number of the automatic cash payment system of the financial institution 34 registered in advance is dialed. After the telephone is connected, the user inputs the PIN code and the amount of money to be taken down by a numeric / symbol key (for example, KEY 9 in FIG. 2) and visual recognition by a small screen display (for example, LCD 8 in FIG. 2).

  When the data is input, the mobile device 32 encrypts the input data and the customer information (name, account number, mobile device number) (for example, the encryption calculation arithmetic circuit 26 in FIG. 2 encrypts the data). Then send. The transmitted data is sent to the computer 30 of the financial institution via a mobile phone carrier company (public telephone network). After decryption and user confirmation are performed at the computer 30 of the financial institution, money is withdrawn from the user's account as digital cash, and the data is encrypted and transmitted to the user's portable device via the public telephone network. The transmitted data is decrypted (for example, decrypted by the cryptographic calculation arithmetic circuit 26 in FIG. 2) and stored in a memory (for example, 25 in FIG. 2) as a digital cache. When a user buys goods or services at the store 35, the near field communication function such as the infrared communication function attached to the portable device 32 is used (for example, using the I / F 27 for short distance communication device in FIG. 2) Data is exchanged with the store terminal 33, and the digital cash is paid as a price by the user's key input operation. At this time, the user receives information about what he / she bought from the store terminal 33 together with the store information.

  This purchase information can be linked to household account book software installed on a PC by connecting the portable device 32 and a PC (Personal Computer) owned by the user with an infrared communication function. Furthermore, for those who do not have a PC or those who do not have household account book software, the household account book service at the service center can be performed by transferring this purchase information to a service center (not shown) that implements the household account book software. It becomes easy.

  Conventionally, this service is possible, but it has not been put into practical use because of complicated data input. In the case of the present invention, purchase information is automatically input. In addition, a service for the user such as using the function of the mobile phone system to notify the time when the user can receive the service by transferring the data of the person who paid the payment from the portable device 32 to the store terminal 33 with the user's permission. Is possible.

  The operation of this system will be described with reference to the system diagram of FIG. 5 and the flowcharts of FIGS. First, an operation for the user to put digital money from the financial institution 34 into the portable device 32 is shown in the flowchart of FIG. When the user wants to obtain digital money, in order to connect to the computer 30 of the financial institution, the user makes a call via the radio base station 31 to the telephone number designated by the financial institution S31.

  When the line is connected, the computer 30 of the financial institution makes a sound to perform a confirmation operation (here, “1” key input is used for confirmation) when withdrawing digital money from the portable device 32. Instruct by. The user listens to the voice instruction and presses the “1” key when confirming the transaction. When the “1” key is pressed, the portable device 32 selects necessary data (for example, bank account number, name, etc.) designated from the data stored in the portable device 32 in advance, and the wireless base station 32 S3 is transmitted via the station 31.

  The computer 30 of the financial institution compares the subsequent data (bank account number, name, etc.) with the data on the computer when the first data transmitted indicates confirmation ("1"), and after confirmation In step S6, a request for inputting the personal identification number is made by voice. After listening to the voice request from the portable device 32, the user presses a key of a personal identification number (for example, a 4-digit number) S7. The portable device 32 encrypts the pressed number with the internal MPU and transmits the data (S8).

  The computer 30 of the financial institution decrypts the received data S9, compares the data with a pre-registered personal identification number, and confirms S10. If the code numbers are different (No), a request for key input of the code number is again made by voice S6. If the personal identification numbers are equal (Yes), a transmission for performing a voice input request for the payment amount is performed S11. After hearing the voice request from the portable device 32, the user presses the key for the payment amount. The portable device 32 displays the data on the small screen display LCD8. The user sees it and presses the confirmation key (special symbol) after confirmation. The portable device 32 transmits the data S12.

  In the computer 30 of the financial institution, the digital money data and the storage permission data (key) based on the received data are encrypted and transmitted (S13). The portable device 32 decrypts the received data with the MPU (S14). If the correct storage permission key is included in the data, the digital money data is stored in the memory S17. Next, FIG. 7 shows a flowchart of processing of the portable device 32 and the store terminal 33 at the time of digital money payment.

  The store clerk inputs an amount to be paid by the customer as the consideration into the store terminal 33 and transmits it to the portable device 32 by the short-range communication device I / F (proximity communication means) 27 (S21). The customer (user) confirms the amount on the small screen display LCD8 S22. If it matches the amount to be paid (Yes in S23), the payment key (special key) of the portable device 32 is pressed S25. Within the mobile device 32, the digital money based on the confirmed payment amount is subtracted from the stored digital money, and the digital money data and the storage permission data (key) based on the confirmed payment amount are encrypted, and the data Is transmitted to the store terminal 33 by the short-range communication device I / F 27 (S26). If it does not match the amount to be paid (No in S23), the non-payment key (special key) of the portable device 32 is pressed S24. In the store terminal 33, when the payment key is pressed, the received data is decrypted in S27, and when the correct storage permission key is included in the data, the digital money data is stored in the memory S30.

  When the customer is a customer of the store, the use point is transmitted from the store terminal 33 to the portable device 32 by the proximity communication means and stored. Next, a service system using the mobile device described in “1. Mobile device”, which is different from the digital money system, will be described. As shown in FIG. 8, the system includes a service center computer 40, a mobile device 32 held by a user (customer), a wireless base station 31 for wirelessly connecting the two devices, and a service. The service provider terminal 36 is provided in the service provider 37 to be provided. The portable device 32 and the wireless base station 31 are the same as those in FIG.

  For new customers of this system, the customer or store clerk determines whether or not to register as a customer, and in the case of registration, necessary data stored in the portable device 32 (name, address, etc.) ) Is transmitted from the portable device 32 to the service provider terminal 36 by the proximity communication means (I / F 27 for short-range communication device) by the customer's key operation and stored, and the customer number etc. is transmitted to the service provider terminal. The data is transmitted from 36 to the portable device 32 by the proximity communication means and stored.

  Thus, based on the collected customer data, service is performed via the service center 44 in the system configuration. FIG. 9 shows a flowchart of the service system. In this service, the telephone number of the user's mobile device (mobile phone) 32 is registered in advance in the service provider terminal 36 as customer information, and the telephone number of the service center 44 and the service protocol ( Store the service rules).

  Thereafter, the store clerk of the service provider 37 registers in advance the message for the customer and the opening time information in the service center 44 (S44). In addition, the service center 44 is notified of changes in store conditions such as the degree of congestion S45. When the user has his / her convenience, he / she wants to service his / her situation (for example, want to eat: 6 / free time: 7) by pressing a designated key (6/7 in this case) of the portable device 32. S41 and S42 transmitted to the center.

  The radio base station 31 that receives this data uses the location information of the mobile device 32 (note that the location information of the mobile communication is used as the location information of the mobile device 32. This location information includes the radio base station 31 and the mobile device. (S32) is attached to this data and transmitted to the service center 44 (S40). In the service center 44, it is determined from the position information of the mobile device 32 whether or not the user's location is within the effective range, and further, it is determined whether or not the registered service provider can provide service (S48). If the current store status is serviceable, a registered voice registered in advance is transmitted to the portable device 32 (S49).

  The user listens to the registered voice from the portable device 32 and determines whether or not to receive the service in S50. If a specific key is pressed to receive, a line is connected to the telephone / automatic reservation system of the service provider to make a reservation S51. Another service using the service system of FIG. 9 will be described with reference to FIGS. 10, 11 and 12. FIG. This is a service providing system that provides a service that matches the feeling of the owner of the mobile device 32. The system configuration is the same as in FIG. However, the portable device 32 shown in FIG. 10 is used.

  Service information storage means (memory) for storing the service provider terminal 36 provided in the service provider 37, the types of services that can be provided by the service provider 37, the service availability status of the service provider, and messages to the user. 41 and a determination means 42 for determining whether or not a service can be provided for the current state of the user, and a radio base station (dedicated radio base station or mobile radio) connected to the service center 44 A part of a communication system) 31, remote communication means (corresponding to 2 in FIG. 2) enabling communication between the radio base station 31 and input means for inputting the current state of the user The mobile device 32 is configured.

Store information is input from the store CTI 51 to the store status database 60 of the service server 50, and personal information is input from the portable terminal 52 to the personal database 61 of the service server 50.

  The service server 50 and the portable terminal 52 and the store CTI 51 and the portable terminal 52 are connected by remote communication. Store data is transmitted from the service server 50 to the portable terminal 52, feeling data is transmitted from the portable terminal 52 to the service server 50, and the registered data is stored in the registration data storage area 63 of the portable terminal 52. Input to the database 61.

  Reservation data is transmitted from the mobile terminal 52 to the store CTI 51, and registration data, voice signal guidance, ticket data, and the like are transmitted from the store CTI 51 to the mobile terminal 52. In FIG. 13, registration data is temporarily stored in the portable terminal 52 and stored in the service server 50. The personal attribute information is stored in the mobile terminal 52, and the ticket and the like are stored in the mobile terminal 52 as time-limited service information.

As a result, it is not necessary for the user to manage the personal database, and data in the personal database can be input by a single button operation of the portable terminal 52 by the user. The following method can be used to register store information.
1. 1. How to register as a customer when visiting the store 2. Method of storing additional electronic information of a program such as WebTV 54 by short-range communication and registering it in the service server 50 later 3. A method of storing electronic information from the Web of the PC 53 and registering it in the service server 50 later. 4. A method for referring to a web page in a magazine on the PC 53 and registering it according to “3.” 5. A method of calling a telephone number in a magazine, storing electronic information in the portable terminal 52, and registering it in the server later. 6. Get store information from a friend 7. Register using the chain store information of the registered store. Registration using registered store cooperation store information Next, as an example of a time-limited service, a service in the case of purchasing a ticket and using a transportation facility will be described.

  When a ticket is bought using the portable device 32, the ticket data is stored in the service center 44 (in the case of this service, the computer system of the transportation facility may execute the application program of this service. ). In addition to the ticket data, the ticket data stores the station (bus stop in the case of a bus) or arrival time, etc., and this data is used to store the data slightly before the user reaches the destination. This is a service that informs by voice.

  The service center 44 stores voice data informing the station or bus stop to be exited in the memory 41, means for setting / canceling a temporary telephone number corresponding to the ticket (not shown), and a train or bus at the destination. A determination unit 42 determines a time slightly before the arrival, and a means for notifying the arrival of the determination result via the radio base station 31 slightly before reaching the destination.

  When the service center 44 uses the same train and gets off at the same station or bus stop, the service center 44 is assigned a temporary telephone number of the same number, and by that phone number, it should be a station or bus stop to get off shortly before reaching the destination. Is notified by voice data. In addition, the service center 44 transmits data indicating arrival, and when the portable device 32 receives the data, the mobile center 32 informs the user that the call has arrived with a bell or the like, or stores it in a memory in advance when the user presses the conversation button. You may make it reproduce | regenerate the audio | speech data which notifies that it is a certain station and bus stop which should get off.

  By giving the same temporary telephone number to a person who receives the same service, transmission from the radio base station need only be performed once. There is a household account book service as another service. In this case, when digital money is paid by the portable device 32, data related to payment contents instead of the receipt from the store terminal 33 is stored in a memory (for example, 25 in FIG. 2) in the portable device 32. This storage can be accumulated for a certain number of times. When the user accumulates a certain amount of data or wants to receive the household account book service, the user can access the service center 44 (in the case of the household account book service, the computer 30 of the financial institution 34). Make a phone call and send your user ID and payment data.

  The service center 44 can create a household account book by inputting these data into the household account book creation application. The created household account book may be printed on paper and sent, but a set-top box that can see still images and can be connected to the portable device 32 is connected to the TV, and the household account book is displayed from the service center 44. The user can also view the still image data to be transmitted to the set top box via the portable device 32 and display the data on the TV. Of course, by inputting data from the portable device 32 directly to a computer that can be connected to the portable device 32 and installed with the household account book software, it is possible to operate the computer and view it on the screen. The operation of inputting content data into the household account book software is simplified.

  As described above, by using this digital money system, it is possible to withdraw money anywhere in a region where a mobile phone can communicate without going to a financial institution. In addition, a system such as an ATM / CD on the financial institution side is not required, and only a computer to which they are connected is required. When the system is operating, money can be withdrawn at any time. Moreover, data input to the household account book software can be performed with a single operation.

  It also eliminates the need to carry both a mobile phone and a wallet / electronic card. Since this portable device has a wallet function, this portable device has a personal identification function, and simplification and customization of communication services for individuals can be achieved. Furthermore, it is possible to pay for the information / communication provision on the spot and not use more than the payment capability.

In the transportation system, it is possible to provide a service for instructing alighting place through the portable device 32. In addition, the system using FIG. 8 allows the user to receive an appropriate service appropriately according to the user's situation (for example, the user's feeling).
3. Attachment for portable terminal The attachment for portable telephone (attachment for portable terminal) of the present invention is extremely effective in an information communication service system including a portable device that can be used by "anytime, anywhere, anyone", and has already been widely used. Is to be used as such a portable device.

  In addition, the cellular phone attachment of the present invention is a device that is in close contact with the cellular phone without losing a sense of unity and is used together with the cellular phone. This not only uses the original telephone communication function of the mobile phone, but also organically connects with various input / output means such as image display means, manual input means and voice input / output means of the mobile phone, and executes various application programs. It is a device that can be made to.

  First, in order to improve 5 portability, 6 human interface, and 7 low-cost mobile devices, mobile phone display (LCD), input key (KEY), speaker (receiver), etc. This is realized as an attachment for a mobile phone that can use the human I / F function of the mobile phone. Specifically, the attachment of the present invention has the same male connector that can be connected to a data communication connector of a mobile phone, and can control all input / output means of the mobile phone by an electrical signal.

  In addition, it is necessary to exchange digital data at a short distance, such as payment of a digital cash, and at that time, communication means that is not charged as communication is used. Therefore, a near field communication I / F (near field communication device) is added to the attachment. Furthermore, in order to handle digital cash and personal data, the data needs to be encrypted / decrypted. Therefore, an encryption / decryption circuit is added to the attachment. Further, since the attachment needs to have a unity design (volume and weight) that does not impair the appearance of the mobile phone, the attachment is, for example, a cube type as shown in FIG. The structure of an attachment for realizing these things is shown in FIG.

  As shown in the lower part of FIG. 18, the attachment 101 includes a general-purpose MPU 232 that can execute a program, a memory 25, a short-range communication device I / F 27, a cryptographic calculation dedicated arithmetic circuit 26, and a data communication IF 29. The MPU 232 is an apparatus in which an OS is mounted to control peripheral devices, and an application program realized by the attachment 101 is executed. Generally, a memory 25 is used.

  The memory 25 stores each user's name, address, owned digital cash, digitized admission ticket, etc., and is read out by the MPU 232 and processed and output to the outside as necessary. In addition, applications for supporting various services are stored. The cryptographic calculation dedicated arithmetic circuit 26 is a device used for encryption / decryption when handling data requiring high security such as application programs for digital money and point cards. Data stored in the memory 25 is encrypted as necessary.

  The short-range communication device I / F 27 is a device for exchanging data with a device provided in the vicinity, and here, an infrared device such as IrDA is used. The data communication I / F 29 is a device that enables communication with the mobile phone 100. The upper part of FIG. 18 shows a general configuration of the mobile phone 100. From the mobile communication IF 2, the modem 3, the codec 15, the protocol controller 24, the MPU 231, the panel I / F 16, a microphone, a speaker, an antenna, an LCD, an LED, and a KEY. Composed.

  In the figure, the same components as in FIG. The protocol controller 24 is a device that determines a data path. For example, such a path is determined that data received by the antenna is transmitted to the outside through the data communication connector 99 or output to the speaker through the codec 15. A command from the MPU 232 of the attachment 101 is sent to the protocol controller 24 of the mobile phone 100 through the data communication IF 29 and the data communication connector 98. The protocol controller 24 analyzes the instruction and determines which input / output means is to be controlled.

  The MPU 231 of the mobile phone executes a control program as a mobile phone and an application program such as an address book. First, the plug & play (active insertion / removal) function of the data communication connectors 98 and 99 is used to switch from the mobile phone program to the attachment program. This attachment program executes a command determined by the protocol controller 24 as a control command to the output means of the LCD, the LED, or the ringer speaker among the commands sent from the MPU 232 of the attachment 101.

  Furthermore, among the commands sent from the MPU 232 of the attachment 101, those which are determined as a control command to the speaker output means by the protocol controller 24 can be output to the speaker, and the digital input from the microphone of the mobile phone 100 can be performed. The signal can be transferred to the attachment 101. The reception data by the cellular phone communication can also be transferred to the attachment 101.

FIG. 19 shows a processing procedure for controlling each input / output means of the mobile phone.
(A) When the protocol controller 24 detects the attachment of the attachment 101, a request for switching the program in the MPU 231 to the attachment program is made (S71). On the other hand, if the protocol controller 24 does not detect attachment of the attachment 101, a request is made to switch the program in the MPU 231 to the mobile phone program S72. Note that the protocol controller 24 is configured so that the programs operate in order.
(B) When a control command is sent from the MPU 232 of the attachment 10, it is determined whether or not it is a command for controlling the mobile phone in S 81, S 82, and if it is not a command for controlling the mobile phone, the control command in the attachment 101 To process S83. If the command is for controlling the mobile phone, the command is transferred to the protocol controller 24 via the data communication connector 98 (S84). The MPU 232 of the attachment 10 performs the processes of S81 to S84.

  When the protocol controller 24 receives a control command from the MPU 232 of the attachment 10, it determines whether it is a control command to the LCD, the LED, or the ring tone speaker S85. If the command is a control command to the LCD, LED, or ringtone speaker, the control command is transferred to the mobile phone MPU 231 and is output from the S87, LCD, LED, or ringtone speaker under the control of the panel I / F 16. The

If it is not a control command for the LCD, LED, or ringtone speaker, it is determined whether it is a control command for the speaker (S90). If it is a control command to the speaker, it is input to the codec 15 in S91, and is output from the speaker in S92. If it is not a control command to the speaker, exception processing is performed and the process ends (S93).
(C) The MPU 231 of the mobile phone 100 determines whether the control state is in accordance with the attachment program in S100 when there is a KEY input, S101 when there is a microphone input, and S102 when there is received data through mobile communication. S103, if not in the control state by the attachment program, the internal processing is performed by the mobile phone program and the process is terminated (S104). In the case of the control state by the attachment program, S105 is transmitted to the MPU 232 of the attachment 101 via the protocol controller 24, the data communication connector 99, and the data communication connector 98. The MPU 232 of the attachment 101 receives the signal and performs processing S106.

  Note that the MPU 231 of the mobile phone 100 and the MPU 232 of the attachment 101 display using the LCD when there is a KEY input, when there is a microphone input, or when there is received data by mobile communication. Also, when the MPU 231 of the mobile phone 100 and the MPU 232 of the attachment 101 send a control command, the display is performed using the LCD.

  Next, with reference to FIGS. 20 and 21, an embodiment in which the mobile phone 100 connected to the attachment 101 can be used as a service device by an application program installed in the attachment 101 will be described in terms of digital money and point card services. If an application program for digital money and a point card service is installed in the MPU 232 of the attachment 101, since it has the cryptographic calculation dedicated arithmetic circuit 26, it is possible to handle data that requires a high degree of security, and for short-range communication devices. With the I / F 27, an IrDA-compliant infrared device can be used as a means for transferring electronic media.

  Replenishment of digital money is performed by the memory 25 of the MPU 232 of the attachment through the path of (antenna) → mobile communication I / F 102 → modulator / demodulator 3 → protocol controller 24 → data communication I / F 29 → MPU 232 as shown in FIG. . In addition, the authentication algorithm required for replenishing digital money or paying or transferring digital money according to B in FIG. 5 can be calculated at high speed by the application program using the cryptographic operation dedicated circuit 26. It is.

  In addition, the user electronically possesses personal information in the memory 25 in the MPU 232 of the attachment 101, and when the service is subscribed, it is subscribed by passing it to the store terminal by infrared communication using the I / F 27 for short-range communication devices. The procedure can be completed. When transferring personal information, it is encrypted by the encryption operation dedicated circuit 26 of the attachment using the public encryption key received from the store in advance and transferred to the store terminal. There is no safety.

  In such applications, payment status such as digital money balance and purchase history, and details of transferred personal information can be confirmed using mobile phone LCD and speaker input / output means such as speaker output voice. can do. For example, when personal information is handed over to a store, it is displayed on the LCD of the mobile phone with a path of “maru 1 → maru 2 → maru 3 → maru 4” in FIG. Can do. In addition, as a result of confirmation, when it is not desired to pass personal information to the store, by inputting KEY, for example, information that is not desired to be passed through the path of “maru 1 → maru 2 → maru 3” in FIG. 20 can be selected. And it can transmit with respect to a store by I / F27 for near field communication devices except the information which it does not want to pass.

  In addition, it is possible to receive a point service that has been different for each store, each chain, and each industry with one attachment 101 possessed by an individual. In order to avoid such annoyance, there are several examples using a magnetic IC card, but it is necessary to check at a specific place in order to see the state of the card. The attachment 101 uses the input / output function of the mobile phone 100 to manage electronic gifts such as points classified by service type, and advises customers that their expiration date is approaching. It is possible to visually present the process until achievement in cooperation with the application.

  In addition, a service is received when points are accumulated, but it becomes possible to accept a request for the service using the communication function of the mobile phone and a service for the request. By using this function, it is possible to perform a digital payment which can be serviced at a location where the mobile phone can communicate and a location where the mobile phone is currently available at a specific location. It is possible to attract the user's interest by being able to fortune at any time. In addition, this system can be automated by a forklift computer, which can contribute to the efficiency of the forklift system.

  By combining mobile phones and attachments, it is possible to provide effective suggestions to customers. By actively using widely used mobile phone displays and voice output, you can borrow other people's mobile phones whenever you like. Provides a framework that allows even things to be confirmed. Since the customer can receive various services simply by connecting various types of inexpensive attachments using the mobile phone already possessed, it is extremely economical from the viewpoint of the customer.

  Since the attachment does not impair the sense of unity when connected to the mobile phone, it is more convenient than other mobile devices used in conjunction with the mobile phone. Since the program installed in the attachment can be switched according to the usage of the service, it is not necessary to have a plurality of attachments, which is convenient. In addition, since any input / output means of the mobile phone can be used, suggestion to customers and information presentation are effective.

  From the viewpoint of the service implementation side, since mobile phones are already widely used, it is only necessary to develop an attachment, and it is more economical than the development of a new portable device having input / output means. Since mobile phones themselves are widely used, there is an effect of spreading services. In the future, even if other new devices (such as GPS, barometers, etc.) appear to interact with the real world, the new devices can be used according to the connection standard of the attachment without changing the mobile phone itself. Inexpensive attachments and application programs can be developed, which is economical.

  By switching the application program installed in the attachment, the mobile phone that is normally carried around can be transformed and used in various service situations. With the mobile phone attachment of the present invention, it is possible to use a mobile phone that has been specialized for conventional communication means as a mobile device for the service as described above, simply by using an attachment that can be easily connected without greatly impairing the appearance. become.
