DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device which can be connected to an IC card capable of storing a large amount of information.

[0002]

In recent years, with the advance of telecommunication technology, communication devices such as portable telephone devices and vehicle-mounted telephone devices have become widespread.
A mobile phone device using a C card has been considered. This is a SIM (SubscriberIdenti
TY Module) card, and inserting the SIM card into the mobile phone device, for example, causes the subscriber number (ID code) stored in the memory of the SIM card to be transferred to and stored in the memory of the mobile phone device. Then, the subscriber number is expanded to enable telephone calls and data communication.

In this case, in addition to the above subscriber number, a memory dial or the like can be stored in the memory of the SIM card.
00 phone numbers can be stored. In a state where, for example, 100 telephone numbers are stored as memory dials in the memory of the SIM card, the user performs a key operation for reading the telephone number stored in, for example, the 31st telephone number. Then, 100 phone numbers from the memory of the SIM card are transferred and stored in the memory of the mobile phone device at a time, and thereafter, only the 31st phone number out of the 100 phone numbers is expanded. Is displayed on the display. Thus, the user can perform a calling operation (calling operation) based on the 31st telephone number displayed on the display.

However, in this case, as described above, 100 telephone numbers stored in the memory of the SIM card are transferred and stored at one time in the memory of the portable telephone device, and thereafter, the 31st telephone number is stored. Is expanded and displayed on the display, so the time required to transfer and store those 100 phone numbers is relatively long, that is, the 31st phone number is displayed on the display. There is a problem that the time until the operation is relatively long and the usability is poor.

In this case, the memory of the SIM card has a structure in which information on whether or not a telephone number is stored cannot be stored due to the limitation of the capacity of the storage area. In the memory of the card, temporarily
Even if 100 phone numbers are not stored as memory dials, for example, only 50 phone numbers are stored, the maximum number of phone numbers that can be stored is 100.
Items are sequentially scanned. Under the circumstances, the above-mentioned problem may occur regardless of the number of telephone numbers stored in the memory of the SIM card, and may occur regardless of the storage order of the telephone numbers read. is there.

The present invention has been made in view of the above circumstances, and has as its object to provide an IC capable of storing a large amount of information.
It is an object of the present invention to provide a communication device in which a card can be connected and in which usability can be improved.

[0007]

According to the first aspect of the present invention, the trigger detecting means receives a large amount of information by the control means.
Priority in addition to the process of transferring the specified number of pieces of information
From priority processing presence / absence determination means
When the control means detects that there is no other priority processing by the priority processing presence / absence determination means,
A plurality of information of a predetermined number of the multiple information stored or to be transferred, or in the storage means in the storing means <br/> plurality of information of a predetermined number of the multiple information stored in the card To an IC card. in this way,
When transferring information between the IC card and the storage means, the control means does not transfer a large number of information at once, but transfers a predetermined number of pieces of information among a large number of pieces of information. Therefore, the amount of information transferred at one time between the IC card and the storage means can be reduced,
Accordingly, the time required for the transfer can be reduced. That is, if a large number of information, for example, 100 phone numbers are stored in the IC card, the 100 phone numbers may be transferred from the IC card to the storage means at a time and stored. Instead, for example, five telephone numbers are transferred to and stored in the storage means as a plurality of pieces of information, so that the transfer time per transfer can be reduced, thereby improving the usability. Can be planned. Further, particularly, when the communication device is, for example, an in-vehicle telephone device and there is a physically large distance between the IC card and the storage unit, or only the communication interface that cannot obtain a sufficient transfer speed is provided. This is valid for communication devices that do not have them.

[0008]

[0009]

[0010]

According to the second aspect of the present invention, the transfer state information
The payment means consists of an IC card and storage
Stores transfer status information that identifies whether data was transferred between
And the control means determines whether or not the transfer is performed based on the transfer state information.
When the presence of missing information is detected, many
A certain number of information including information that has not been transferred
The data is transferred between the IC card and the storage means. That is,
When a large number of information, for example, 100 telephone numbers are stored in the IC card, and the user performs a key operation to read the telephone number stored in, for example, the 32nd telephone number, the designated key is designated. If the 32nd telephone number has already been transferred and stored in the storage means, it is not necessary to transfer and store the 32nd telephone number again, and in that case, the above-described transfer processing is prohibited. Thus, power consumption can be reduced correspondingly, and the specified 32nd telephone number can be read out promptly.

This will be described with reference to the flowchart shown in FIG.

As a premise, 100 telephone numbers are stored as memory dials in the memory dial storage area of the memory 9a of the SIM card 9 as shown in FIG. As shown in FIG. 5, it is assumed that no telephone number is stored in the memory dial storage area 14 and the transfer status flags are all set to “0” accordingly.

First, when the control circuit 10 is executing a main routine waiting for a key operation of an outgoing call process or a key operation of an incoming call process, the user enters a memory dial storage area of the memory 9 a of the SIM card 9. For example, 31
The telephone number (05) stored in the item (address 30)
2-222-xxx), when the "call" key, "3" key, and "1" key are sequentially operated, the control circuit 10 exits the main routine described above. The process proceeds to the memory dial reading process shown in FIG.

The control circuit 10, which has shifted to the memory dial reading process, sets the telephone number designated by the key operation in the memory dial storage area of the memory 14, ie, 31.
The transfer state flag corresponding to the telephone number that can be stored in the item is read, and the transfer state flag is determined (step S).
1).

Here, the transfer status flag corresponding to the telephone number which can be stored in the memory dial storage area of the memory 14 and corresponding to the 31st telephone number is shown in FIG. 4 because no telephone number is stored. As described above, since it is set to “0”, the control circuit 10 determines “YES” in step S2, and stores the 31st telephone number specified by the key operation in the memory dial storage area of the memory 14. Judge that it is not stored.

Next, the control circuit 10 controls the SIM card 9
A predetermined number of telephone numbers (a plurality of pieces of information according to the present invention) including the designated telephone number stored in the memory dial storage area of the memory 9a are transferred to and stored in the memory dial storage area of the memory 14 ( Step S3).

More specifically, the control circuit 10 controls the 5th to 35th telephone calls including the 31st telephone number stored in the memory dial storage area of the memory 9a of the SIM card 9. No. (052-222-xxxx ~ 052
-666-xxxx) as shown in FIG.

The control circuit 10 controls the memory 1
No. 4, a predetermined number of telephone numbers stored in the memory dial storage area, that is, a telephone number designated by a key operation among five telephone numbers from the 31st to the 35th, that is, a 31st telephone number Expand the telephone number (step S5),
The 31st telephone number is displayed on the display 4 (step S6), and the process returns to the main routine described above. Thereby, the user can display the 31st telephone number (052-222) displayed on the display.
−xxxx) can be performed based on the outgoing call operation (calling operation).

Now, following this, the user sets S
Key operation for reading out the telephone number (052-333-xxx) stored in the memory dial storage area of the memory 9a of the IM card 9 in, for example, the 32nd (address 31), for example, "call It is assumed that the "" key, the "3" key and the "2" key are sequentially operated.

In this case, the control circuit 10 that has shifted to the memory dial reading process in accordance with the key operation performs the above-described process to set the telephone number in the memory dial storage area of the memory 14 that can be stored as the 32nd telephone number. Since the corresponding transfer state flag has been updated to "1", "NO" is determined in the above-described step S2, and the 32nd telephone number specified by the key operation is stored in the memory dial storage area of the memory 14. It is determined that it has been done.

Then, the control circuit 10 develops the telephone number stored in the memory dial storage area of the memory 14 and designated by the key operation, that is, the 32nd telephone number (step S5). , The 32nd telephone number is displayed on the display 4 (step S
6) Return to the main routine described above. As a result, the user can perform a calling operation (calling operation) based on the 32nd telephone number (052-333-xxx) displayed on the display.

Here, following this, the user sets S
A key operation for reading out a telephone number (0566-22-xxx) stored in the memory dial storage area of the memory 9a of the IM card 9 and stored in, for example, the 51st (address 50), for example, "Call It is assumed that the "" key, the "5" key and the "1" key are sequentially operated.

In this case, the control circuit 10 which has shifted to the memory dial reading process in accordance with the key operation, sets the transfer state flag in the memory dial storage area of the memory 14 corresponding to the 51st telephone number that can be stored. Is set to “0”, “Y” is set in step S2 described above.
ES ”, and determines that the 51st telephone number specified by the key operation is not stored in the memory dial storage area of the memory 14.

Then, the control circuit 10 displays the 51st telephone number specified by the key operation on the display 4 by executing the above-described steps S3 to S5 (step S6). As a result, the user can display the 51st telephone number (0566-) displayed on the display.
22-xxxx) can be performed based on the calling operation (calling operation). In this case, in step S4, as shown in FIG.
The 55 phone numbers for the 55th case (0566-22-XXX)
X to 0566-66-xxxx) is updated from "0" to "1".

The above is the description of the memory 9a of the SIM card 9.
Has been described in the case where a telephone number stored as a memory dial in the memory dial storage area is transferred to the memory 14 of the mobile phone 1. Even when a telephone number stored as a memory dial in the memory dial storage area is transferred to the memory 9a of the SIM card 9, the same processing is performed.
Not only the telephone numbers stored as memory dials in the memory dial storage area, but also the telephone numbers stored as outgoing histories in the aforementioned outgoing call history storage area and the telephone numbers stored as incoming histories in the incoming call history storage area. The number is also transferred between the memory 14 of the mobile phone 1 and the memory 9a of the SIM card 9 by the same processing.

As described above, according to the first embodiment, when the user performs a key operation for reading a telephone number stored as a memory dial in the memory 9a of the SIM card 9, the control circuit 10 Numerous (for example, 100) stored as memory dials in the 9 memories 9a
Is not transferred and stored in the memory 14 of the mobile phone device 1 at a time, but a plurality of (for example, five) phone numbers including the phone number designated by the key operation are transferred to the memory 14. Since the telephone number is stored and only the telephone number specified by the key operation is expanded and displayed on the display 4, the time until the telephone number specified by the key operation is read can be reduced. Thereby, usability can be improved.

In particular, in the first embodiment, a desired telephone number can be read by key operation. When the user performs a key operation for reading a telephone number stored in the memory 9a of the SIM card 9 as a memory dial, the telephone number specified by the key operation is already stored in the memory 14 of the mobile phone device 1. When the telephone number is transferred and stored, the control circuit 10 does not cause the telephone number specified by the key operation to be transferred and stored again, so that the power consumption can be reduced accordingly. , The telephone number specified by the key operation can be quickly read.

Next, a second embodiment of the present invention will be described with reference to FIG.
Description will be made with reference to FIG. The same portions as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, different portions will be described. In this second embodiment, as shown in FIG. 8, the control unit In the mobile telephone device 21, tri
The control circuit 22 as a moth detecting means and a priority processing presence / absence determining means is provided with a timer 23. The timer 23 detects whether or not a predetermined time has come, and determines whether or not there is another priority processing. Is to be detected.

Next, regarding the operation of the above configuration, in particular,
The process executed by the control circuit 22 when the SIM card 9 is electrically connected to the mobile phone device 1 will be described with reference to the flowchart shown in FIG.

It should be noted that, in this case, as in the first embodiment, the memory dial storage area of the memory 9a of the SIM card 9 has 100 memory dials as shown in FIG. As shown in FIG. 5, no telephone number is stored in the memory dial storage area of the memory 14 of the portable telephone device 21, and accordingly, all the transfer state flags are set. It is assumed that “0” is set.

First, when the control circuit 22 detects that a predetermined time has come by the timer 23 during the execution of the main routine waiting for the key operation of the transmission process, the key operation of the incoming call process, and the like. Alternatively, when it is detected that there is no other priority process, the process exits the main routine and proceeds to the memory dial reading process shown in FIG.

The control circuit 22, which has shifted to the memory dial reading process, reads the transfer state flag in the memory dial storage area of the memory 14 and judges the transfer state flag (step S11). Then, the control circuit 22
When it is detected that the transfer state flag is set to "0", "YES" is determined in the step S12, and among the telephone numbers stored in the memory dial storage area of the memory 9a of the SIM card 9, the memory It is determined that there is something not stored in the memory dial storage area 14.

Next, the control circuit 22 causes a predetermined number of telephone numbers including the telephone number whose transfer state flag is set to "0" to be transferred to the memory dial storage area of the memory 14 and stored therein (step S13). At this time, the transfer status flags corresponding to the predetermined number of telephone numbers are updated from "0" to "1" (step S14), and the process returns to the main routine described above (return).

When the timer 23 detects that the next predetermined time has come, or detects that there is no other priority processing, the control circuit 22 executes the above-mentioned memory dial reading processing, When it is detected that the transfer state flag is set to “0”, the processes of steps S12 to S14 described above are repeatedly executed. On the other hand, when the control circuit 22 does not detect that the transfer state flag is set to “0”, the control circuit 22 determines “NO” in step S12, and
It is determined that all the telephone numbers stored in the memory dial storage area of the memory 9a of the card 9 have been transferred and stored in the memory dial storage area of the memory 14, and a transfer completion notification is made (step S15). Is returned. Then, the control circuit 22 that has shifted to the main routine executes the transfer completion notification in step S15 described above, and thereafter,
There is no transition to the memory dial reading process.

As described above, according to the second embodiment, when the control circuit 22 detects that the predetermined time has been reached by the timer 23 or that there is no other priority processing, the control circuit 22 executes the operation of the SIM card. Instead of having a large number (for example, 100) of telephone numbers stored as memory dials in the memory 9a of the mobile phone 9 transferred and stored in the memory 14 of the mobile phone device 1 at a time, a plurality of telephone numbers are stored in the memory 14a.
Therefore, the transfer time can be reduced for each transfer, and the above-described transfer processing can be executed without any user's awareness.

The present invention is not limited to the above-described embodiment, but can be modified or expanded as follows. The communication device is not limited to the mobile phone device, and may be applied to other communication devices such as a vehicle-mounted phone device, a home phone device, and a pager.

The number of telephone numbers that can be stored as a memory dial is not limited to 100, but may be any other number. The number transferred at a time is not limited to five, The number may be such that the user does not feel inconvenience in operation due to the processing speed.

The information that can be stored is not limited to the memory dial, but may be any data included in the portable telephone device, such as personal information (PIM), schedule, and address book.

The timing at which the transfer process is executed is not limited to the timing at which a key operation is performed or the timing at which a predetermined time is reached by a timer. It may be the timing at which the incoming signal is received.
