Description

  The present invention relates to a portable wireless communication system in which a communication service can be used by mounting a subscriber card (hereinafter referred to as a USIM card (Universal Subscriber Identity Module)) that stores a subscriber's identification code.

  In addition to the conventional GSM (Global System for Mobile Communications) communication method that has already been deployed in many countries and regions, the mobile phone is a third-generation CDMA (Code Division Multiple Access) that will be deployed worldwide in the future. In both cases, a communication service can be used by installing a USIM card that stores a subscriber identification code. The USIM card is a type of memory card, and in addition to identification information (ID) corresponding to each user's telephone number and billing information to the user, phonebook information etc. with limited capacity are written ( Patent Document 1).

  In a mobile phone device that can use a communication service by installing this USIM card, a user can use a plurality of terminals by replacing one USIM card with a plurality of terminals, or a plurality of terminals It is possible to provide a flexible communication environment in which a user can use one terminal only by an operation of replacing a USIM card.

  Therefore, it is becoming common for a user to use a plurality of terminals according to the purpose (work / private etc.). As a result, there is an increasing demand for an environment in which only the customization information set by the user himself / herself to improve usability and the data necessary for the intended use can be easily extracted. Here, the customization information is information such as registering frequently used icons as shortcuts on the liquid crystal screen or setting the LCD screen as a favorite wallpaper.

  In addition, both WCDMA and GSM use technologies such as HSDPA (High Speed Downlink Packet Access) and EDGE (Enhanced Data GSM Environment), which makes it possible to significantly increase the data communication speed and increase the network communication environment. In view of the possibility of changing, it is expected that the necessity of using a plurality of terminals depending on the purpose (work / private etc.) will increase in the future.

Japanese Patent Laid-Open No. 2002-300254

  In the case of the invention described in Patent Document 1, when a user uses another terminal, personal data in the internal memory is copied to the external memory or the like before the USIM card is removed. Processing such as unlocking the USIM card slot is performed, and from the viewpoint of preventing leakage of personal information, measures are taken such as erasing or initializing data in the internal memory after the copying is completed.

  However, these processes are very complicated. For example, in a situation where a plurality of terminals are properly used depending on the application, the USIM card is replaced with another terminal to execute another application. Until the copy of personal data stored in the memory is completed, the card slot is not unlocked, so it cannot be switched immediately, and it is very user-friendly for actual use. .

  An object of the present invention is to solve the above problems in a mobile phone device in which a communication service can be used by mounting a subscriber card (USIM card) that stores a subscriber identification code. An object of the present invention is to provide a means capable of improving the convenience of the user when the mobile phone terminal is used for different purposes.

  The portable wireless communication system of the present invention includes a portable wireless communication terminal that can use a communication service of a communication network by mounting a subscriber card (hereinafter referred to as a USIM card) that stores a subscriber identification code, and the communication A network server provided with a user dedicated memory for storing personal information of the USIM card user transmitted from a portable wireless communication terminal attached to the USIM card and connected to a network, the portable wireless communication terminal comprising: Means for detecting that a USIM card is installed, accessing a user dedicated memory of the network server, receiving personal information of the USIM card user and downloading it to an internal memory of the portable wireless communication terminal; Stores in the internal memory when a card is installed and used Means for uploading the updated personal information to the network server when an update operation of the personal information is performed or at predetermined time intervals, and the network server includes the USIM card When a request for downloading the personal information of the USIM card user is received from the portable wireless communication terminal with the card attached, the personal information of the USIM card user stored in the user-dedicated memory is transmitted to the portable wireless communication terminal. And means for updating the personal information of the USIM card user stored in the user-occupied memory in the network server with the personal information uploaded from the portable wireless communication terminal.

  In the present invention, for example, when a user alternately uses a plurality of portable wireless communication terminals by replacing a USIM card, the USIM card is inserted and connected to a network to be used for the portable wireless communication terminal in use. By mirroring the internal memory and the user-occupied memory in the network server, the personal information of the user stored in the user-occupied memory in the network server is always kept up-to-date. When the user changes the terminal used by replacing the USIM card with another portable wireless communication terminal, the user automatically accesses the user-occupied memory when the communication establishment of the terminal is completed, and the latest personal information is obtained. By downloading and deploying in the internal memory of the terminal, the terminal to be used can be switched immediately.

  The mobile radio communication terminal can be realized as a mobile phone, the network server is connected to a mobile phone base station, and the mobile radio communication terminal uses the mobile phone function to download and upload the personal information. Thus, it is possible to employ a configuration having means for executing via the mobile phone base station.

  Alternatively, the mobile wireless communication terminal can be configured to have a mobile phone function and a WLAN function, the network server is connected to a mobile phone base station and a WLAN base station, and the mobile wireless communication terminal The information downloading and uploading can be configured to include means for selecting either the mobile phone function or the WLAN function and executing the information via either the mobile phone base station or the WLAN base station. .

  Furthermore, the portable wireless communication terminal of the present invention includes a short-range wireless communication means capable of direct communication between portable wireless communication terminals and the USIM card immediately before the personal information can not be downloaded via the base station. It can be set as the structure which has the function to transfer the said personal information by the connection of terminals using the said short distance wireless communication means from the portable radio | wireless communication terminal with which it was mounted | worn.

  As described above, according to the present invention, it is possible to effectively use the network connection means such as a mobile phone and a wireless LAN (WLAN) and the communication means possessed by each terminal to overcome the above-described problems.

  According to the present invention, in a mobile phone device in which a communication service can be used by mounting a subscriber card (USIM card) that stores a subscriber identification code, a user uses a plurality of terminals by replacing the USIM card. In this case, personal information including the environment setting of the original terminal used by the user can be easily and quickly developed on a newly used terminal without performing complicated operations.

  In addition, since the mirroring of the internal memory of the terminal being used and the user-occupied memory in the network server is performed in real time or at regular intervals, the user loses personal information including his / her environment settings. It can be easily restored.

  Furthermore, since the personal information in the memory cannot be accessed without authentication such as an identification code, the confidentiality of the personal information can be maintained.

  FIG. 1 is a block diagram showing a first embodiment of the portable radio communication system of the present invention.

  In FIG. 1, (1-a) and (1-b) are terminals such as mobile phones, and terminal antennas (1-a-1) and (1-b-1), mobile phone radio units (1 -a-2), (1-b-2), control unit (1-a-3), (1-b-3), ROM / RAM (1-a- 4), (1-b-4), EEPROM (1-a-5), (1-b-5), operation unit (1-a-6), (1 -b-6), USIM card slot (1-a-7), (1-b-7), audio processing unit (1-a-8), (1-b-8), microphone (1-a- 9), (1-b-9), receiver (1-a-10), (1-b-10), speaker (1-a-11), (1-b-11), image processing unit (1 -a-12), (1-b-12), display section (1-a-13), (1-b-13), camera (1-a-16), (1-b-16), etc. I have.

  (1-c) is a communication network that provides communication services to the terminals (1-a), (1-b), etc., and the terminal antennas (1-a-1), (1-b-1) and A mobile phone base station (1-c-2) having a base station antenna (1-c-1) to be wirelessly connected, a network server (1-c-3), and the like are provided. When the USIM card (1-d) is installed in the USIM card slot (1-a-7), (1-b-7), the terminals (1-a) and (1-b) -C) Communication service can be received. Therefore, for example, when changing the terminal used by the user from the terminal (1-a) to another terminal (1-b), remove the USIM card (1-d) from the terminal (1-a). , Perform the act of replacing the terminal (1-b).

  In this embodiment, in such a situation, the updated personal information of the user is connected to the network server (1-c-3) in the communication network (1-c) using the mobile phone communication means, Uploads data to the user-occupied memory in real time during use. Real-time connection means that the user uses one of the terminals (1-a) and (1-b) and performs data update operations on the terminal or at a preset time interval. Connected to the user-occupied memory in the server (1-c-3) via the cellular phone packet communication network, and mirrored with the contents of the internal memory of the terminal, all of the user's personal data or setting information It is an act of keeping a part of the latest information.

  As a result, even if the user changes the terminal to be used by replacing the USIM card, the latest personal data and setting information are already uploaded in the network server. By downloading from the server designated using the communication means, data migration before and after the terminal change becomes smooth.

  FIG. 2 is an explanatory diagram showing an operation procedure when the terminal to be used is changed from (1-a) to another terminal (1-b) in the present embodiment. Hereinafter, the operation of the present embodiment will be described in detail with reference to FIGS. 1 and 2.

  The USIM card is a subscriber card that recognizes a user identification code, and is a memory card in which identification information corresponding to a subscriber's telephone number is written. By inserting this USIM card (1-d) into the USIM card slot (1-a-7) of the terminal (1-a) or the USIM card slot (1-b-7) of the terminal (1-b), Internal information is read by the control unit (1-a-3) or control unit (1-b-3), and functions such as voice calls and mail transmission / reception by the terminal (1-a) or terminal (1-b) Can be used.

  First, it is assumed that the user uses the USIM card (1-d) inserted into the terminal (1-a). Accordingly, the terminal (1-a) can be connected to the network server (1-c-3) in the communication network (1-c) via cellular phone communication (2-1, 2-2). At this time, since the USIM card (1-d) is not inserted in the terminal (1-b), communication using the cellular phone communication network is impossible (2-3).

  The terminal (1-a) and the communication network (1-c) are connected by mobile phone communication, and communication data from the mobile phone base station (1-c-2) in the communication network (1-c) When the signal is transmitted through the antenna (1-c-1), the terminal (1-a) transmits the radio wave transmitted from the base station antenna (1-c-1) at the terminal antenna (1-a-1). The signal is received and amplified to a level that can be processed by the control unit (1-a-3) in the cellular phone radio unit (1-a-2). The control unit (1-a-3) processes the signal amplified by the radio unit, and if it is a voice call, it sounds the speaker (1-a-11) via the voice processing unit (1-a-8). Make a voice call by operating the microphone (1-a-9) and the receiver (1-a-10). On the other hand, in the case of data communication, the information content is displayed on the display unit (1-a-13) via the image processing unit (1-a-12).

  These operations and all other operations such as mail creation and phone book registration are performed in the operation unit (1-a-6), and received mail data, image data, voice data, etc. are controlled by the control unit (1-a- 3) and stored in the ROM / RAM (1-a-4), and the phone book data is stored in the USIM card (1-d) or the EEPROM (1-a-5). For telephone directory registration, the user can arbitrarily set whether to store in the USIM card or in the EEPROM. The USIM card (1-d) is portable, but the memory capacity is small and there is an upper limit on the number of registrations, so it can be registered in the EEPROM (1-a-5) and the user can select the memory depending on the registration partner. Yes.

  In this embodiment, when the user is using the terminal (1-a) and the internal memory is changed by an operation such as setting change or phone book registration (2-4), the control unit ( 1-a-3) reads the changed data from the ROM / RAM (1-a-4) and the EEPROM (1-a-5), and transmits the terminal antenna (1) through the radio unit (1-a-2). -a-1) connects to the communication network (1-c) (2-5).

  The communication network (1-c) receives data received from the terminal (1-a) via the base station antenna (1-c-1) and the mobile phone base station (1-c-2). Send to -c-3). The network server (1-c-3) has a user-occupied area, and the network server (1-c-3) uses the data received from the mobile phone base station (1-c-2) to The user-occupied memory is updated (2-6).

  As a result, the user's setting information is always stored in the network server (1-c-3) at the same time, so it is possible to save the latest information in a storage area other than the terminal used by the user. . As for the frequency of this update, it is performed in real time whenever a change is made to the internal memory by an operation such as setting change or telephone directory registration as described above, or at a predetermined time interval. Can be set in advance.

  Thereafter, when the terminal used by the user is changed from the terminal (1-a) to the terminal (1-b), the USIM card (1-d) is changed to the USIM card slot (1--) of the terminal (1-a). Remove from a-7) (2-6) and replace the USIM card slot (1-b-7) of terminal (1-b). The terminal (1-a) from which the USIM card (1-d) is removed cannot communicate using the mobile phone communication network (2-7, 2-8).

  On the other hand, the control unit (1-b-3) of the terminal (1-b) recognizes that the USIM card has been inserted through the USIM card slot (1-b-7), and the mobile phone radio unit (1- A radio wave is transmitted from the terminal antenna (1-b-1) via b-2), and the cellular phone communication with the communication network (1-c) is established (2-9, 2-10). The terminal (1-b) makes a request for access to the user-occupied memory designated by the USIM card in the network server using the cellular phone communication function immediately after the communication establishment work is completed (2-11). Here, the communication network identifies the user from the identification code of the USIM card and permits access to the user-occupied memory in the network server (1-c-3) (2-12).

  After this, the user occupies the network server (1-c-3) to the terminal (1-b) via the mobile phone base station (1-c-2) and the base station antenna (1-c-1). The latest personal data and setting information stored in the memory are downloaded (2-13). The received data is processed by the control unit (1-b-3) via the terminal antenna (1-b-1) and the mobile phone radio unit (1-b-2). It is stored in RAM (1-b-4) and EEPROM (1-b-5).

  Also, the address information in the network server (1-c-3) where personal information is stored may be stored in the USIM card (1-d) at the time of data update at the terminal (1-a), The address information of the network server stored in the control unit (1-a-3) of the terminal (1-a) is converted into two-dimensional barcode information by the image processing unit (1-a-12), and the display unit (1 -a-13) may be displayed.

  Display unit of terminal (1-a) displaying address information converted into two-dimensional barcode information when USIM card (1-d) is inserted into terminal (1-b) and personal data is downloaded Is captured by the camera (1-b-16) of the terminal (1-b), so that the control unit (1-b-3) captures the captured image via the image processing unit (1-b-12). The address information of the network server in which the personal information of the user is stored can be obtained. With this configuration, even if the USIM card (1-d) is lost and another person uses the lost USIM card (1-d), the network server that stores the user's personal information is saved. Access can be prevented and security can be increased.

  With the above, even if the user changes the terminal to be used from the terminal (1-a) to the terminal (1-b), the latest environment settings and phone book data are always deployed promptly without complicated work. It becomes possible.

  FIG. 3 is a block diagram showing a second embodiment of the portable radio communication system of the present invention.

  The mobile terminal in this embodiment has a wireless LAN (WLAN) function in addition to the mobile phone function. Since the operation of the mobile phone function is substantially the same as the content described in the first embodiment, the description of the parts common to the operation of the first embodiment is omitted. A difference in configuration from the first embodiment is that the terminal of this embodiment can be connected to a network server via TCP / IP in addition to a cellular phone communication network.

  In the present embodiment, when the user is using the terminal (3-a) and the internal memory is changed by an operation such as setting change or phone book registration, the mobile phone communication network or It connects to the network server (3-c-3) of the communication network (3-c) through the WLAN line, and updates the personal information of the user at an arbitrary address in the server. Further, as in the first embodiment, the update frequency is executed in real time every change, or at predetermined time intervals. Further, which of the cellular phone communication network and the WLAN line is used will be described later.

  Here, regarding the connection with the WLAN line, the control unit (3-a-3) of the terminal (3-a) has been changed from the ROM / RAM (3-a-4) and the EEPROM (3-a-5). Data is read out and connected to the communication network (3-c) via the WLAN radio unit (3-a-15) and the WLAN terminal antenna (3-a-14). In the communication network, the WLAN base station antenna (3-c -4), it becomes possible to connect to the network server (3-c-3) by authenticating via the WLAN base station (3-c-5). As described in the first embodiment, the user setting information is always stored in the network server (3-c-3) at the same time, so that the latest information is stored in the memory other than the terminal used by the user. Information can be saved.

  Thereafter, when the terminal used by the user is changed from the terminal (3-a) to the terminal (3-b), the USIM card (3-d) is changed to the USIM card slot (3-a) of the terminal (3-a). Remove the card from a-7) and replace it with the USIM card slot (3-b-7) of the terminal (3-b). Then, similarly to the case of the first embodiment, the terminal (3-a) cannot communicate using the mobile phone communication network.

  On the other hand, the control unit (3-b-3) of the terminal (3-b) recognizes that the card has been inserted through the USIM card slot (3-b-7), and the mobile phone radio unit (3-b- The radio wave is transmitted from the terminal antenna (3-b-1) via 2), and the communication network (3-c) and the cellular phone communication are established. In the present embodiment, the terminal (3-b) accesses the communication network through the mobile phone communication network or the WLAN line immediately after the completion of the communication establishment work. Here, as in the case of the first embodiment, the communication network identifies a user from an identification code or the like and permits access to personal information in the network server (3-c-3).

  Thereafter, the latest personal data and setting information are downloaded to the terminal (3-b) through the cellular phone communication network or the WLAN line. The received data is processed by the control unit (3-b-3), and is appropriately stored in the ROM / RAM (3-b-4) and the EEPROM (3-b-5) depending on the type of data.

  As for the address information in the network server (3-c-3) in which personal information is stored, the USIM card (3-d) is used when updating data in the terminal (3-a), as in the first embodiment. Or the network server address information stored in the control unit (3-a-3) of the terminal (3-a) can be stored in the image processing unit (3-a-12). It may be possible to display the information on the display unit (3-a-13). When the USIM card (3-d) is inserted into the terminal (3-b) and the personal data is downloaded, the terminal (3-a) displaying the address information converted into two-dimensional barcode information is displayed. By photographing the display unit with the camera (3-b-16) of the terminal (3-b), the control unit (3-b-3) passes the captured image through the image processing unit (3-b-12). Thus, the security can be enhanced by obtaining the address information of the network server storing the personal information of the user.

  The above-mentioned determination of the connection means between the cellular phone communication network and the WLAN line is that the user can individually set each terminal in advance or that the terminal arbitrarily selects from the radio wave condition (communication speed), etc. Any of the configurations may be used. FIG. 4 is a flowchart showing an example of the connection network selection operation. Hereinafter, a method for selecting the connection network will be described with reference to FIGS. In this embodiment, the user manually sets the priority order of the connection network to the network server from the operation units (3-a-6) and (3-a-7) of each terminal, Alternatively, the automatic selection is set in advance, but only one of them may be set.

  When the USIM card (3-d) is installed and the terminal (3-a) is in use and settings are changed or phone book registration is performed, and the internal memory is changed, or the terminal (3-b) When the USIM card (3-d) is inserted into the USIM card slot (3-b-7), the controller (3-a-3) or (3-b-3) connects to the network server. Determine whether the network setting is manual or automatic (4-1). If manual is set, select whether to connect via the cellular phone communication network or via the WLAN line. Instruct (4-2).

  When the user chooses to connect via the mobile phone network, the control unit (3-a-3) or (3-b-3) is connected to the mobile phone radio unit (3-a-2) or (3- Operate b-2), first check whether it is possible to connect to the mobile phone network in that environment (4-3), and if it is connectable, determine the connection network as the mobile phone network (4-4) and Establish and upload or download personal information (4-5). If the connection is not possible in (4-3), the control unit (3-a-3) or (3-b-3) is connected to the WLAN radio unit (3-a-15) or (3 -b-15) is started (4-6), and it is confirmed whether it can be connected via a WLAN line (4-7). If connection is possible, the connection network is determined as a WLAN line (4-4), and communication is performed. To upload or download personal information (4-5). If it is impossible to connect even with the WLAN line in (4-7), communication is temporarily failed (4-8), and retry is performed when either communication is established.

  Similarly, when the user selects to connect via the WLAN line in (4-2), the control unit (3-a-3) or (3-b-3) activates the WLAN radio unit, Check whether it is possible to connect with a WLAN line in that environment (4-9). If connection is possible, determine the connection network as a WLAN line (4-4), establish communication, and upload or download personal information. Perform (4-5). If the connection is not possible in (4-9), the control unit (3-a-3) or (3-b-3) operates the mobile phone radio unit (4-10) It is confirmed whether or not connection is possible via the telephone network (4-11). If connection is possible, the connection network is determined to be a mobile telephone network (4-4), and communication is established to upload or download personal information ( 4-5). If it is impossible to connect even in the cellular phone network in (4-11), communication is temporarily failed (4-8), and a retry is performed when either communication is established.

  Next, when it is set to automatically set the connection network in (4-1), the control unit (3-a-3) or (3-b-3) is the mobile phone radio unit and the WLAN radio. Are connected to each connection network simultaneously (4-12), and it is confirmed whether both connection networks are connectable (4-13). If possible, the control unit measures the throughput when each line is connected (4-14), determines the line with a better communication environment (4-4), and uploads or downloads personal information (4). -5). If both connections are not possible in (4-13), it is confirmed whether communication is possible in either one of the communication networks (4-15), and if possible, the connection network is determined (4-4). ), Uploading or downloading personal information (4-5). If it is not possible to connect to either connection network in (4-15), communication is temporarily failed (4-8), and retry is performed when either communication is established.

  With the above, even if the user changes the terminal to be used from terminal (3-a) to terminal (3-b), the latest environment settings and phone book data are always deployed promptly without complicated work. It is possible to provide a mobile phone terminal and a network environment that are possible.

  FIG. 5 is a block diagram showing a third embodiment of the portable radio communication system of the present invention. In this embodiment, in addition to the second embodiment, each of the terminals (5-a) and (5-b) has a Bluetooth (BT) unit, an IR (infrared communication) unit in addition to the mobile phone communication network and the WLAN connection. Etc. All or some of them.

  Further, the USIM card (5-d) has a connection information section regarding devices that can be connected to the terminals (5-a) and (5-b). When the USIM card (5-d) is inserted into a terminal, this connection information section recognizes devices that can be connected to a network other than the mobile phone connection network, or devices that can directly connect terminals. However, it has a configuration that can be memorized.

  Consider the case where the USIM card (5-d) is replaced from the terminal (5-a) to the terminal (5-b). When the USIM card (5-d) is inserted into the control unit (5-b-3) of the terminal (5-b), device information that can be connected to the terminal (5-a) is transferred to the USIM card (5-d). It is possible to recognize from the connection information part. Therefore, it is detected by the connection detection unit in the control unit (5-b-3) whether it has the same device as its own connectable device. In addition, the priority of the connected device is set in advance in the control unit (5-b-3), and the priority of the faster device is set higher depending on the connection speed with the mobile phone communication network as the highest priority. Considering a terminal as shown in FIG. 5, the order is the mobile phone communication network, WLAN line, BT connection, and IR connection.

  Next, selection of this connection network will be described with reference to the flowcharts of FIGS. FIG. 6 shows only the case of data download. However, in the case of connection to a network server (5-c-3) via a cellular phone communication network or a WLAN line, the first and second implementations are shown. Similar to the mode, an operation of updating personal information by mirroring is performed. However, in the case of BT connection and IR connection, only downloading of personal information is executed from the terminal in which the USIM card (5-d) was inserted immediately before.

  The terminal (5-b) in which the USIM card (5-d) is inserted first tries to connect to the mobile phone communication network in order to obtain personal information (6-1). If connection is possible, the connection switching unit in the control unit (5-b-3) determines that the connection network is a mobile phone communication network (6-2), establishes communication, and establishes a network server (5- Download personal information from c-3) (6-3). If connection is not possible in (6-1), the control unit (5-b-3) determines whether the terminal (5-b) has a WLAN function from the connection information unit in the USIM card (5-d). Confirm (6-4), and if the connection is possible, the connection switching unit in the control unit (5-b-3) determines the connection network as a WLAN line (6-5) and establishes communication. The personal information is downloaded from the network server (5-c-3) (6-3).

  When the terminal (5-b) does not have a WLAN function, the control unit (5-b-3) determines whether the terminal (5-b) and the terminal (5-a) have a BT function or not by the USIM card (5-d). (6-6), if both terminals have the BT function, the connection switching unit in the control unit (5-b-3) determines the BT connection between the terminals. (6-7) If the authentication is successful (6-8), communication by the BT function is established between both terminals, and the internal memory of the terminal (5-a) is transferred to the internal memory of the terminal (5-b). Data transfer is performed (6-9).

  If both or one terminal does not have the BT function in (6-6), or if authentication fails in (6-8), the control unit (5-b-3) ) And whether the terminal (5-a) has the IR function from the connection information section in the USIM card (5-d) (6-10). If both terminals have the IR function, the control section ( The connection switching unit in 5-b-3) determines the IR connection between the terminals (6-11), and the speaker (5-b-11) via the voice processing unit (5-b-8) To prompt the user to make an IR connection (6-12).

  When the user brings the IR parts (5-a-19) and (5-b-19) of both terminals close to each other and succeeds in the authentication (6-13), the user establishes communication by the IR function and establishes the terminal (5-a ) From the internal memory to the internal memory of the terminal (5-b) (6-9).
