Description

  The present invention relates to a technique for sharing personal data of a single user among a plurality of portable terminals.

  In recent years, mobile phones based on next-generation standards such as IMT-2000 (so-called third generation mobile phones) have been developed. Such a third-generation mobile phone has a structure in which a mechanism medium (IC card) in which subscriber information and the like are recorded is separated from the mobile phone body.

  In the third-generation mobile phone, each user has a UIM (User Identity Module: sometimes referred to as USIM or R-UIM) card. This UIM card is an IC card in which subscriber information (contractor information) and other information (such as a telephone book) are recorded.

  The user can use the service in any third generation mobile phone by inserting his / her UIM card into the main body.

  Also in the conventional GSM mobile phone, subscriber information is stored in a SIM (Subscriber Identity Module) card as in the above UIM card.

  By using these UIM cards and SIM cards, a single user can use a plurality of mobile phones, and a single mobile phone can be used by a plurality of users.

  Therefore, in order to ensure personal privacy and to share personal data described later with a plurality of mobile phones in a third generation mobile phone that can use the above usage pattern, not only contractor information but also various types Ideally, all personal data can be stored in a personal UIM card.

  Here, the personal data is, for example, information such as a phone book, e-mail, schedule, and image files taken with a camera built in a mobile phone, which are input by the user.

  However, it is impossible to hold all personal data in one UIM card due to restrictions on the size and storage capacity of the UIM card. Therefore, practically, most of these personal data are recorded in the mobile phone body.

Here, in Patent Document 1, by securing a folder area for personal data for each IMSI in a non-volatile memory in a mobile phone so that different IMSI, that is, different UIM card owners cannot refer to the folder, A technique for ensuring privacy is disclosed.

  Note that the device configuration of the mobile phone (100) (FIG. 1: in particular, the configuration provided for wireless communication) is merely an example, and various general techniques can be employed at present. Detailed description in this embodiment will be omitted.

  FIG. 2 is a configuration diagram of the personal data memory (20) in the nonvolatile memory (7). In the figure, an area is secured for each IMSI in the personal data.

  In the present embodiment, there is a personal data area (21) for IMSI = A and a personal data area (22) for IMSI = B.

  Each personal data area includes a corresponding ISMI and corresponding telephone directory data, mail data, browser data, image data, communication data, and the like. Note that these areas may be secured statically or dynamically.

  FIG. 3 is a configuration diagram of the synchronization management memory in the nonvolatile memory (7). In the figure, the synchronization management memory (30) configures a synchronization management memory area (31) for each synchronization partner terminal and synchronization target IMSI, which includes the synchronization partner terminal ID (311), the IMSI (312) to be synchronized, and the individual. A synchronization status area (313 for managing the synchronization status with the partner terminal for each minimum unit of data (in the case of a telephone book, an individual unit identified by a memory number, a mail in the case of mail, an image file in the case of an image, etc.) These areas may be secured statically or dynamically as in the personal data memory (20).

  FIG. 4 is a state transition diagram showing the transition of the synchronization state of data managed in the synchronization state region (313).

  FIG. 5 is a flowchart of processing performed when the central control unit (3) detects insertion of the UIM card (14).

  FIG. 6 is an image diagram of a use environment according to the present embodiment. In the figure, the user first inserts and uses the UIM card (63) in the terminal A (61), and then moves the UIM card (63) to the terminal B (62) for use. At that time, the personal data of the terminal A (61) is copied (synchronized) to the terminal B (62).

  FIG. 7 is a sequence diagram showing the flow of signals when copying (synchronizing) personal data.

  FIG. 8 is a flowchart of processing performed when the central control unit (3) receives the personal data transmission start request (706) of FIG.

  FIG. 9 is a flowchart of processing performed when the central control unit (3) receives the personal data transmission request (708) shown in FIG.

  Next, referring to FIGS. 2, 3, 4, 5, 7, 8, and 9, the UIM card (63) is transferred from the terminal A (61) to the terminal B (62) shown in FIG. The processing operation of the software program of the central control unit (3) in FIG. 1 when transferring and synchronizing data will be described.

  As a precondition, it is assumed that IMSI = A is written in the UIM card (63), terminal A (61) has a usage history with IMSI = A, and terminal B (62) has a usage history with IMSI = B. Therefore, the personal data memory (20) of the IMSI = A exists in the personal data memory (20) of the terminal A (61), and the personal data of IMSI = B exists in the personal data memory (20) of the terminal B (62). Region (22) exists. Further, it is assumed that telephone memories 000, 001, 010, and 020 are written in the terminal A (61) as personal data.

  First, the operation when the terminal A (61) is activated with the UIM card (63) inserted into the terminal A (61) will be described. At this time, the UIM card (14) detection process shown in FIG. 5 is started.

  In FIG. 5, the central control unit (3) reads IMSI = A from the UIM card (14) (step S51).

  Next, the IMSI stored in the existing personal data area (21) of the personal data memory (20) is compared with the read IMSI (step S52). In this case, since both coincide with A, the result is “Yes”, and the process is terminated.

  Next, the operation when the UIM card (63) is moved to the terminal B (62) and the terminal B (62) is activated in FIG. 6 will be described. At this time, the UIM card (14) detection process shown in FIG. 5 is started as described above.

  In FIG. 5, the central control unit (3) reads IMSI = A from the UIM card (14) (step S51).

  Next, the IMSI stored in the existing personal data area (22) of the personal data memory (20) is compared with the read IMSI (step S52). In this case, since they do not match, the result of S52 is “No”, it is determined that a new addition is made, a new personal data area is created, the contents are initialized, and the read IMSI is written in the IMSI storage area (step S53). . By this processing, a personal data area is secured for each IMSI, and privacy is maintained.

  Next, terminal A (61) and terminal B (62) are connected using a communication interface such as USB (12), BT (13), etc., and signal exchange is performed when copying and synchronizing personal data. 7 will be described together with the sequence chart of FIG.

  First, it is assumed that the link between both terminals has been established (702), and the link establishment procedure (701) is omitted.

  First, the user performs a personal data reception request operation at the terminal B (62) (703). At this time, whether the data is all or a selected part, whether it is received unconditionally or only the difference changed on the terminal A (61) side after the previous copy is given as a parameter. Therefore, it is assumed that “Receive all unconditionally” is selected.

  When the central control unit (3) of the terminal B (62) receives this request, it requests the input of a PIN (Personal Identification Number) for user authentication (704), and the user inputs the correct PIN ( 705) and a personal data transmission start request (706) is transmitted to the terminal A (61).

  The personal data transmission start request (706) includes IMSI = A held in the UIM card (63) and the terminal ID of the terminal B (62) as parameters.

  Upon receiving the personal data transmission start request (706), the central control unit (3) on the terminal A (61) side starts the processing shown in the flowchart of FIG.

  In FIG. 8, IMSI = A included in the received personal data transmission start request (706) signal is searched from the personal data memory 20 to determine whether or not it exists (step S81). In this embodiment, since IMSI = A exists, the result is “Yes”, and then the partner terminal ID area (311) of the synchronization management memory (30) is searched to see if it has been synchronized before. Is determined (step S82).

  Since this process is the first synchronization, the result is “No”, a new synchronization management memory area (31) is created, and the terminal ID of the terminal B (62) is stored in the terminal ID area (311) in the same area. Write IMSI = A in the IMSI area (312) to be synchronized. Further, the synchronization state of the synchronization state area (313) corresponding to the telephone memories 000, 001, 010 and 020 is initialized as “1: synchronization required” as a registered record (step S83).

  Then, “personal data transmission start request acceptance” (707) is transmitted to terminal B (62) (step S84).

  If “No” in the determination in step S81, “personal data transmission start request rejection” is transmitted (step S85).

  Next, the terminal B (62) transmits a personal data transmission request (708). The personal data transmission request (708) includes the above-mentioned parameter indicating “receive all unconditionally”.

  The central control unit (3) on the terminal A (61) side that has received the personal data transmission request (708) activates the process shown in the flowchart of FIG.

  In FIG. 9, since the processing target included in the received personal data transmission request (708) signal is “all”, the phonebook memory 000, which is the first record, is set as the first processing target (step S901).

  Then, the state of the synchronization state area 313 corresponding to the processing target record is determined (step S902). In the case of the current process, all the synchronization status areas need 1: synchronization, so the telephone book memory 000, which is the process target record, is transmitted (step 904 and signal 709), and the same area becomes 0: synchronization unnecessary ( Step S905 and Ev2 in FIG. 4).

  The processes in steps S902 to S905 described above are performed for all records (steps S906 and S907).

  When transmission of all data is completed, personal data transmission completion (712) is transmitted (step S908), personal data transmission completion acceptance (714) is received (step S909), and the process is completed.

  Next, the UIM card (63) is returned to the terminal A (61), the phone book memory 000 is corrected, the phone book memory 030 is added, and the phone book memory 001 is deleted. Returning to (62), the processing operation when personal data is synchronized will be described.

  First, when the telephone directory memory 000 is corrected, the synchronization status area 3131 corresponding to the same area becomes 0: synchronization unnecessary, but 1: synchronization is required (Ev3). Further, when the telephone directory memory 030 is added, the synchronization state area 3135 corresponding to the same area needs 1: synchronization from NoData (Ev1). When the phone book memory 001 is deleted, the synchronization status area 3132 corresponding to the same area is changed from 0: synchronization unnecessary to 2: deletion (Ev5). It should be noted that 1: even if correction is performed again in the synchronization necessary state, the same state remains (Ev4), and 1: deletion is performed from the synchronization necessary state, 2: deletion (Ev6).

The following is a summary.
Phonebook memory 000 synchronization status area 3131 = 1: synchronization required Phonebook memory 001 synchronization status area 3132 = 2: deletion Phonebook memory 030 synchronization status area 3135 = 1: synchronization required

  Next, only the difference from the first synchronization in the second synchronization operation will be described.

  It is assumed that “only all differences” is selected as the parameter of the personal data reception request operation (703) and personal data transmission request (708) in FIG.

  First, the operation from the link establishment procedure (701) to the transmission of the personal data transmission start request (706) is the same, and the description thereof will be omitted.

  Upon receiving the personal data transmission start request (706), the central control unit (3) on the terminal A (61) side starts the processing shown in the flowchart of FIG.

  In FIG. 8, it is the same as the first synchronization until the judgment start in step S82. Since this process is the second synchronization, the result is “Yes”, and “personal data transmission start request acceptance” (707) is transmitted to terminal B (62) (step S84).

  Next, the terminal B (62) transmits a personal data transmission request (708). The personal data transmission request (708) includes a parameter indicating that “only all differences are received”.

  The central control unit (3) on the terminal A (61) side that has received the personal data transmission request (708) activates the process shown in the flowchart of FIG.

  In FIG. 9, since the processing target included in the received personal data transmission request (708) signal is “all”, the phonebook memory 000, which is the first record, is set as the first processing target (step S901).

  Then, the state of the synchronization state area 313 corresponding to the processing target record is determined (step S902). In the case of the current process, if the processing target record = phone book memory 000 and 030, the synchronization state area 1: synchronization is necessary, so the telephone book memory 000 that is the processing target record is transmitted (step 904 and signal 709). Then, the same area is set to 0: synchronization is unnecessary (step S905 and Ev2 in FIG. 4). If the processing target record = phone book memory 001, the determination is 2: deletion, so a “record deletion request” is transmitted to the terminal B (62) (step S910), and the synchronization status area of the phone book memory 001 3132 is deleted (steps S911 and Ev7).

  According to the above-described embodiment, since shared (also referred to as synchronization) data is automatically selected for each UIM card, the user does not need to select his / her data, and the sharing operation can be simplified.

  Further, since only the difference can be transmitted (synchronized), the transmission (synchronization) time for the second and subsequent times can be reduced.

  The above-described embodiment is a preferred embodiment of the present invention, and various modifications can be made without departing from the gist of the present invention. For example, the processing for realizing the function of the device may be performed by causing the device to read and execute a program for realizing the function of the mobile phone (100) in the above embodiment. Further, the program is transmitted to another computer system by a transmission wave via a computer-readable recording medium such as a CD-ROM or a magneto-optical disk, or via a transmission medium such as the Internet or a telephone line. Also good.
