Examples of the present invention will be described below.
FIG. 1 is a conceptual diagram of a control method for a portable terminal system according to the present invention. FIG. 2 is an example of a block diagram of a portable terminal system according to the present invention. FIG. 3 is a conceptual diagram showing an embodiment of a portable terminal system to which the portable terminal system control method according to the present invention is applied. FIG. 4 is an example of a control flowchart of the mobile terminal used in the mobile terminal system shown in FIG.
In the present embodiment, the case of schedule data as user-specific information will be described.
The feature of this embodiment is that the user-specific information of the mobile phone 10-1 as one mobile terminal is added to the schedule data delivered as shown in FIG. 1, and the mobile phone 10 as the other mobile terminal is added. The mobile phone 10-2 receives user-specific information and performs authentication to restrict redistribution to another mobile phone 10-3 to prevent secondary distribution.
[Configuration of Example]

As shown in FIG. 2, a mobile phone 10-2 as the other mobile terminal mainly includes an antenna 11, a radio high-frequency unit 12 that receives and transmits radio waves, and a baseband that processes audio signals and controls communication procedures. And a SIM card 30-2 having SIM2 information.
The radio high-frequency unit 12 includes a reception analog unit 13, a transmission / reception switch 14, and a transmission analog unit 15.
The reception analog unit 13 mainly includes a local oscillation circuit, an LNA (Low Noise Amplifier), a mixer, and an IF (intermediate frequency) amplifier.
The transmission analog unit 15 is mainly configured by IF modulation, a mixer, and a power amplifier.

The baseband unit 19 includes a CPU (Central Processing Unit) 20, a DSP (Digital Signal Processor) 21, a modem 22, and an AD / DA converter 23. The baseband unit 19 is connected to the image processing unit 18, the memory 24, the speaker 27, the microphone 28, the key 29, and the SIM card 30-2.
The memory 24 includes a flash memory 25 and an SRAM 26. A camera 16 and an LCD 17 are connected to the image processing unit 18.

Here, the SIM card 30-2 is issued in a credit card size like other general IC cards, but only the IC chip portion (trapezoidal shape) is used separately.
A unique number called IMS (International Mobile Subscriber Identity) is assigned to the SIM card 30-2. By linking this IMS and the phone number of the mobile phone 10-2, communication with other mobile phones can be performed. It is supposed to be possible.

By inserting and removing the SIM card 30-2 from the mobile phone 10-2, the phone number can be transferred to another mobile phone, or a plurality of phone numbers can be switched and used by one mobile phone.
However, the SIM card 30-2 is not intended to be frequently inserted and removed, and it is necessary to turn off the power of the mobile phone in order to reliably turn off the power before the insertion and removal. For this reason, many mobile phones have a structure in which the SIM card cannot be inserted or removed without removing the battery.

  The cellular phone 10-1, 10-3 to 10 -n having the same structure as the SIM card 30-2 is configured to relay call data, mail data, image data, etc. via the base station 40. It has become.

Next, the configuration of an embodiment of the portable terminal system according to the present invention will be described in detail with reference to the drawings.
Referring to FIG. 3, the mobile phone 2 (10-2) for managing the schedule, the SIM card SIM2 (30-2) inserted in the mobile phone 2 (10-2), and the mobile phone 2 (10- 2) the mobile phone 1 (10-1) whose schedule is managed, the SIM card SIM1 (30-1) inserted in the mobile phone 1 (10-1), and the SIM card SIM1 (30-1) SIM information 1 that is information for identifying the mobile phone 2 (10-2) that stores the received schedule, and the mobile phone 3 (10-3: 10-3: not related to) managed and managed. 2).

These cellular phones 1 (10-1) to 3 (10-3) operate as shown in FIG.
The cellular phone 1 (10-1) updates the schedule and transmits the schedule data by mail.
The SIM card SIM1 (30-1) is inserted into the mobile phone 1 (10-1), and possesses mobile number information for identifying the user of the mobile phone 1 (10-1).
The SIM information 1 is information for specifying the SIM card SIM1 (30-1), and is added to the user-specific information when the schedule information is transmitted.
The mobile phone 2 (10-2) receives schedule data from a plurality of mobile phones 10 and manages them.
The SIM card SIM2 (30-2) is inserted into the mobile phone 2 (10-2), and possesses mobile number information for identifying the user of the mobile phone 2 (10-2).
The memory 24 of the mobile phone 2 (10-2) stores schedule data received by the mobile phone 2 (10-2).
The mobile phone 3 (10-3) cannot try secondary distribution from the mobile phone 2 (10-2).

[Description of Operation of Example]
Next, the operation of the embodiment of the present invention will be described in detail with reference to the flowchart of FIG.
First, as a precondition, the mobile phone 2 (10-2) registers the SIM information 1 in advance in a scheduler (not shown) (step S1). As a result of this registration, “every time the schedule of the mobile phone 1 (10-1) in which the SIM card SIM1 (30-1) is attached is updated, the mobile phone 2 in which the SIM card SIM2 (30-2) is attached ( 10-2) ”(step S2).
The cellular phone 2 (10-2) waits for the schedule to be updated by the cellular phone 1 (10-1) (step S3).
The mobile phone 2 (10-2) determines whether or not the schedule of the mobile phone 1 (10-1) has been updated (step S4), and when the schedule is updated by the mobile phone 1 (10-1) ( (Step S4 / Yes), the schedule data to which the SIM information 1 is automatically added is sent to the cellular phone 2 (10-2) by mail (Step S5).
When the mobile phone 2 (10-2) receives the schedule data, it is updated to the latest information (step S6).
In the memory 24 of the mobile phone 2 (10-2), the schedule of the owner of the mobile phone 2 (10-2) and the schedule (s) of others are stored and managed by the mobile phone 2 (10-2). .

SIM information 1 is added to the schedule data, and the SIM information 1 is compared with the SIM2 information during the transmission operation by the cellular phone 2 (10-2) (step S8).
The mobile phone 2 (10-2) determines whether the SIM1 information and the SIM2 information match (step S9). If the SIM1 information matches the SIM2 information (step S9 / Yes), the mobile phone 1 ( 10-1) can be transmitted and the process ends.
If the SIM1 information and the SIM2 information do not match (step S9 / No), transmission is impossible (step S11), and the process proceeds to step S8. That is, even if an attempt is made to transmit user-specific information from the mobile phone 2 (10-2) to the mobile phone 3 (10-3), the SIM information is different and cannot be transmitted, and secondary distribution of the user-specific information is prevented. Note that normal telephone calls and data communication can be performed.
As described above, according to the present embodiment, when the user-specific information is primarily distributed from one mobile terminal to the other mobile terminal, the user-specific SIM information is added to the user-specific information. By prohibiting secondary distribution of information from the other mobile terminal to the other mobile terminal, the user from the other mobile terminal to the third party mobile terminal that does not have the SIM information of the user of one mobile terminal Since it is not possible to transmit the unique information even if it is to be distributed, it is possible to prevent the distribution of the user specific information between one mobile terminal and the other mobile terminal to a third party.

[Explanation of effects]
The first effect is that personal information leakage can be prevented. The reason is that SIM information for secondary distribution impossible can be added to the schedule data.
The second effect is that the latest schedule of others can be managed in real time. This is because the latest schedule can be automatically transmitted when updated.

  In this embodiment, the case is described in which the user-specific information is schedule data. However, the present invention is not limited to this, and the user-specific information may be image data or customer information.

  The present invention can be used for a portable terminal system.
