In recent years, however, it has not been uncommon for a single user to own a plurality of mobile phones and use them properly according to the purpose of use, in recent years where the mobile phone system has become very popular. For example, it is rare that two mobile phones are owned, one is mainly used for telephone calls, and the other is used for data transmission by inserting a card type terminal into a PC card slot or the like of an information terminal. Absent.

However, in the case of such a use form, 2
One user will have two different phone numbers, even if they do not use two mobile phones at the same time, so keep in touch if you do not carry two mobile phones at all times (In general, others do not know which phone number to call), and the user himself may be confused as to which phone number is currently being used. .

On the other hand, in the GSM cellular telephone system in Europe, a SIM (Subscriber Identification Module: Subs
By attaching a module called a "criber Identity Card" to a cellular phone, a unique number that depends on the individual user without depending on the terminal (ie, the same unique number if the user is the same even if the terminal is different) Communication can be performed based on the

However, in the case of the SIM module, a mechanical contact structure (connector) is required to connect the communication terminal body and the SIM module, so that the cost is increased and the contact structure is small. Since there is a certain limit to the miniaturization, there is a problem that it is difficult to reduce the size of the communication terminal itself.

In view of the above, the present invention proposes a method of transferring subscriber information that enables one SO to be used by several communication terminals without using a SIM module, and a communication terminal having such a function. The purpose is to do.

BEST MODE FOR CARRYING OUT THE INVENTION

(A) Embodiment (A-1) Configuration of PHS Cellular Phone Hereinafter, a communication terminal apparatus and a subscriber information transfer system according to the present invention will be described using a PHS mobile phone as an example. In this embodiment, it is assumed that SO (subscriber information) is transferred using a communication mode (transceiver mode) between slave units of the PHS mobile phone.

FIG. 1 shows, as functional blocks, basic components related to the present invention in the PHS portable telephone according to the present embodiment. The PHS mobile phone shown in FIG. 1 includes an antenna 1, a radio unit 2, a control unit 3, an audio processing unit 4, a display unit 5, and an operation unit 6.

Of these, the display unit 5 and the operation unit 6 do not necessarily need to be in the same housing as the PHS mobile phone, but use the corresponding functions provided in other electronic devices. Is also good. For example, when the PHS mobile phone adopts a card-type product form, the display unit 5 is a display screen of a computer, and the operation unit 6 is a keyboard and a mouse of the computer.

Similarly, the microphones and speakers connected to the audio processing unit 4 are not limited to those provided in the same housing as the PHS mobile phone, but may be connected to a computer or the like (whether external or external). Irrespective of whether it is a built-in type).

The control section 3 is the most important functional block in the present embodiment. The control unit 3 includes a CPU 31, a program and data memory 32, and a control logic circuit 3.
3, SO data memory 34, and PSID memory 3
5, a temporarily stored data memory 36, and a status memory 37.

Of these, the function blocks other than the temporary storage data memory 36 and the status memory 37 are the function blocks conventionally provided in the PHS portable telephone, and are not new as the function blocks themselves.

For example, the control logic circuit 33 includes an address decoder circuit for converting an address designated by the CPU 31 into an address on a memory, as in a normal PHS portable telephone terminal, and a clock frequency for standby and use. A circuit for switching, a circuit necessary for controlling a frequency used in the radio unit 2, and the like are included.

The external interface is an interface for connecting an external device such as a test apparatus or a computer to a PHS portable telephone.

However, the program and data memory 3
2 stores an SO (subscriber number) data transfer program necessary to realize a function unique to the present embodiment, and the CPU 31 outputs SO data based on an SO data transfer instruction from a user. It can be used for transfer processing.

The SO data memory 34 for holding SO (subscriber number) data has conventionally not been able to freely rewrite data contents by user operation. However, the SO data memory according to this embodiment In the case of 34,
It can be rewritten whenever necessary.

That is, if the user desires to transfer SO (subscriber number) data, he or she is free to use one PH at any time.
The SO data held in the S mobile phone is
The data can be rewritten to the SO data memory 34 of the HS mobile phone. When SO (subscriber number) data does not exist (including when SO data is erased at the time of initial setting or cancellation, etc.), all data portions corresponding to SO data are stored in the SO data memory 34. It is "0".

On the other hand, the temporary storage memory 36, which is a configuration unique to the present embodiment, is storage means used to temporarily hold SO data related to transfer during a series of SO data transfer operations. Is provided in order to avoid a situation such as loss of SO (subscriber information) data.

The status memory 37 stores the S
This is storage means for storing data indicating whether valid data is stored in the O data memory 34 (ie, whether or not the telephone is usable). Thereby, SO
This prevents a situation in which a PHS mobile phone having no data is used by mistake. The contents of this data are confirmed when the power is turned on or when communication is started.

(A-2) Transfer Operation of Subscriber Information Subsequently, an operation necessary for transferring the subscriber information between the two PHS terminal telephones having the above configuration and executed in each PHS portable telephone. The operation performed will be described.

Here, the PHS portable telephone P shown in FIG.
SO from the S (A) side to the PHS mobile phone PS (B) side
The case where (subscriber information) is transferred will be described. That is, at this time, only the PHS mobile phone PS (A) can perform communication via the public network, the PHS mobile phone PS (B) cannot perform such communication, and can only perform communication between slave units. Shall be.

Hereinafter, a series of transfer operations will be described with reference to FIG.

(A-2-1) Preparation work The user who wants to switch the terminal used for communication via the public network from the PHS portable telephone PS (A) to another PHS portable telephone PS (B) is as follows. First, a special operation is performed for each of the PHS portable telephones PS (A) and PS (B), and each telephone is set to the SO transfer mode.

The special operation referred to here is a special operation that is impossible at first in a normal operation, and is an operation defined in advance for the SO transfer mode. For example,
This refers to turning on the power while pressing and holding two predetermined dial keys at the same time, or drawing a special graphic on a display screen using a mouse connected to a computer.

When the special operation is performed, each of the PHS portable telephones PS (A) and PS (B) stores data indicating that it is unusable in the status memory 37 of the control unit 3 (in this example, " 0 "). In this case, the PHS mobile phone PS (B) is in an unusable state from the beginning.

Next, in order to use each terminal in the communication mode between slave units, the user inputs the PSID (PS call code: a number inherent to the PHS telephone) of the other party from the operation unit 6 as the communication partner. input.

When this operation is performed, PHS portable telephones PS (A) and PS (B) send out PSIDs to confirm both, and thereafter, PHS portable telephone PS (A)
The communication mode of (A) and PS (B) is changed to the communication mode between child devices.

(A-2-2) Transfer operation of SO (subscriber information) When the above operation is performed, first, the PHS portable telephone PS (B) to which the SO (subscriber information) is transferred is set up. , S
O data request signal to the other PHS mobile phone PS
(A).

The PHS receiving this SO data request signal
The mobile phone PS (A) reads the SO data from the SO data memory 34, and reads the SO data from the wireless unit 2 and the antenna 1
Are transmitted in order.

When the PHS portable telephone PS (B) receives the SO data via the antenna 1 and the radio section 2, it stores this in the temporary storage data memory 36 and a confirmation signal (confirmation 1 in the figure). Is sent.

At this time, when an error in the received data is detected by the error detection code received together with the SO data, the PHS portable telephone PS (B)
It outputs a SO data retransmission request without sending a confirmation signal (confirmation 1 in the figure). Then, after again storing the received SO data in the temporary storage data memory 36,
The contents are confirmed, and a confirmation signal (confirmation 1 in the figure) is transmitted.

When a confirmation signal (confirmation 1 in the figure) is received,
PHS mobile phone PS (A) is a PHS mobile phone PS
In preparation for a transfer failure in (B), the SO data is stored again in the temporary storage data memory 36, and then the contents of the SO data memory 34 are erased (for example, all bits corresponding to the SO data are set to “0”). Do). When the completion of the erasure is confirmed, a confirmation signal (confirmation 2 in the figure) is transmitted to the PHS portable telephone PS (B).

Upon receiving the confirmation signal (confirmation 2 in the figure), the PHS portable telephone PS (B) writes the SO data stored in the temporary storage data memory 36 into the SO data memory 34, and Erase the contents of the memory (for example, set all bits corresponding to SO data to “0”
To). When the completion of the erasure is confirmed, a confirmation signal (confirmation 3 in the figure) is sent to the PHS mobile phone PS (A).
Is sent.

After receiving the confirmation signal (confirmation 3 in the figure) through the above procedure, the PHS portable telephone PS (A) deletes the SO data held in the temporary storage data memory 36 and outputs the confirmation signal (confirmation in the figure). Send confirmation 4). As a result, the PHS mobile phone PS (A) completely loses the SO data, and only the PHS mobile phone PS (B) holds the SO data.

Upon receiving the confirmation signal (confirmation 4 in the figure), the PHS portable telephone PS (B) determines that the transfer of the SO data has been completed normally, and informs the status memory 37 that it can be used. Data (in this example,
Write "1").

Subsequently, the PHS portable telephone PS (B)
A confirmation signal (confirmation 5 in the figure) is transmitted to the transfer source PHS mobile phone PS (A). Then, the PHS mobile phone PS (B) notifies the user of the completion of the series of transfer operations by sound or display display.

On the other hand, the PHS portable telephone PS (A) similarly receives a confirmation signal (confirmation 5 in the figure) and
After confirming that all the transfer of the O data has been completed successfully, a confirmation display is made by sound or display.

As described above, the transfer of the SO data itself is as follows.
It is performed automatically and does not require any special operation by the user.

(A-3) Effects of the Embodiment As described above, according to the present embodiment, the subscriber information can be transferred by using the inter-slave communication function.
Two PHS mobile phones can be used separately with one SO (subscriber information).

Also, with this function, a user who does not use two PHS portable telephones at the same time only needs to make a contract for one subscription with a communication carrier.
The monthly basic subscription fee can be reduced from two conventional vehicles to one vehicle, and the usage fee can be reduced accordingly.

Further, if subscriber information is transferred by communication between slave units, the distance between two terminals can be set short, so that stable and secure transfer can be performed. , And S
When the O data is transferred, the temporary storage data memory 36 is interposed, and a series of transfer operations are performed through a confirmation operation using a confirmation signal. Therefore, even if a failure occurs in the SO data transfer process, the previous processing can be performed. It is easy to return, and the security of the transfer operation can be further enhanced.

Further, since the status memory 37 is used, the PH without the SO (subscriber information) is used.
A situation in which the S mobile phone is used erroneously can be avoided in advance, and a waste of the transmission band can be prevented.

(B) Other Embodiments In the above embodiment, the user has two PHs.
The case of having an S mobile phone has been described, but the same applies to a case of having three or more PHS mobile phones in that SO (subscriber information) is transferred between two selected PHS mobile phones.

In the above-described embodiment, the PHS portable telephone PS (B) that has received the SO data transfer sends a confirmation signal (confirmation 1 in the figure) to the transfer source PHS portable telephone PS (A). Has been described, the received SO data may be returned as it is instead of the confirmation signal. By doing so, the identity of the transmission contents can be confirmed, and erroneous transmission of SO data can be more reliably eliminated.

In the above-described embodiment, the SO data is directly transferred between the two PHS portable telephones. However, the SO data may be transferred after being encrypted or subjected to a predetermined encoding process. You may do it. In this way, confidentiality and security at the time of transferring SO (subscriber information) can be further improved.

Also, in the above-described embodiment, a case has been described in which two PHS portable telephones are kept at hand, a special operation is performed on both, and then the subscriber information transfer mode is entered. Phone-only operation (the other,
The subscriber information may be transferred by remote control by the PHS mobile phone).

Further, in the above-described embodiment, the case where SO (subscriber information) is transmitted by wireless communication using the communication mode between slave units has been described. It may be executed by wired communication connected via the Internet. In addition, the above functions may be realized by optical communication such as infrared communication.

Further, in the above-described embodiment, the case where SO (subscriber information) is transferred in the communication mode between slave units has been described, but it may be realized by communication via a base station or a connection device.

In the above embodiment, the PHS
Although a mobile phone has been described as an example, even when SO (subscriber information) is transferred between a cellular type mobile phone, a mobile information terminal with a communication function, and the like, the SO is required between different types of communication terminal apparatuses.
(Subscriber information) can also be applied. However, in the case of using the communication mode between slave units, these functions need to be available in the current cellular mobile phone and the like.
