BEST MODE FOR CARRYING OUT THE INVENTION A wireless integrated data card writing adapter (hereinafter, referred to as an adapter) of the present invention is applied to a wireless integrated data card (hereinafter, referred to as a data card).

FIG. 1 is a block diagram showing the basic configuration of the adapter of the present invention. This adapter is applied to a wireless integrated data card that can be used as a PC card conforming to the PCMCIA standard. The illustrated adapter includes a PC card slot 11, a PCMCIA interface 12 connected to a connector in the PC card slot 11, and a microprocessor (MPU) 13 connected to the PCMCIA interface 12.
1, a ROM 132, and a power supply unit 14.

The PCMCIA interface 12 performs a configuration operation based on the PCMCIA standard with a data card. The MPU 131 controls each part of the adapter and controls the data card. ROM
132 stores a command set for controlling the data card, a control program of the MPU 131, and the like. The MPU 131 has a power / reset switch 15
And the input / output unit 16 are connected. The power / reset switch 15 instructs the adapter to power on, power off, reset, and the like. The input / output unit 16 is an input means (input key in the illustrated example) for instructing the operation of the adapter.
And an output means for displaying the status of the adapter [buzzer and LED (light emitting diode) in the illustrated example]. The power supply unit 14 is connected to the PCMCIA interface 12 via a switch SW controlled by the MPU 131, and supplies power to each unit of the adapter and supplies power to the data card inserted into the PC card slot 11 according to the drive voltage. . Note that a dry battery is usually used as a power source.

FIG. 2 is a block diagram showing a basic configuration of a data card to which the adapter of the present invention is applied. This data card is used as a PC card of the PCMCIA standard, and has the same functional blocks as an existing wireless integrated data card. The data card shown in FIG. 2 includes a PC card connector 21 and a PCMCIA interface 22 connected to the PC card connector 21.
A control / signal processing unit 23 connected to the PCMCIA interface 22;
, An antenna 25 connected to the wireless unit 24, and a power supply unit 26.

The PCMCIA interface 22 performs a configuration operation based on the PCMCIA standard with a host computer. The control / signal processing unit 23 performs an MPU that performs various controls centering on service control for operating as a wireless data card, a baseband LSI that operates based on various wireless data communication protocols stored in a protocol ROM, and error retransmission. It has a data error control IC for performing control and correction control, buffering means for data exchanged with the host PC, and the like. The radio unit 24 is a functional block similar to the radio unit of a general PHS terminal, that is, a radio transmission unit that converts a baseband frequency to a transmission / reception frequency, a radio reception unit that converts a transmission / reception frequency to a baseband frequency, It has a local oscillation unit used for frequency conversion, a switching unit for switching between transmission and reception to realize a time-division transmission / reception operation, and the like. The power supply unit 26 is connected to the PC card connector 21.
The power supply from the host computer (adapter in the present invention) via the PC is distributed to each unit.

The operation procedure of the adapter when writing public subscriber data to the data card will be described with reference to the flowchart shown in FIG.

When the power of the adapter is turned on by operating the power / reset switch 15, the apparatus enters a state of waiting for insertion of a data card into the PC card slot 11.

When the data card is correctly inserted into the PC card slot 11 (step 101), a ground wire is connected between the data card side and the adapter side, and the PCMCI is connected.
The A interface 12 recognizes "PC card inserted".

Next, with respect to the inserted data card,
Card initialization processing is performed (step 10).
2). This card initialization process is also called a configuration operation, and is a normal process performed when a data card is inserted into a PC card slot of a host computer. According to the PCMCIA standard, a PC card inserted into a PC card slot is in a memory interface mode, and is first recognized as a memory card by a host computer. When the host computer reads the setting information held by the PC card and recognizes that the PC card is an I / O card (data card, modem card, or the like) other than a memory card, the host computer reads the PC card. The I / O card interface mode is set, so that signals can be exchanged with the host computer. The adapter of the present invention uses the same procedure as a normal host computer,
The PCMCIA interface 12 performs the configuration operation of the above procedure based on the PCMCIA standard. The data card set to the I / O card interface mode is in a state where commands from the adapter can be received.

Next, when the operator taps the write start key of the input / output unit of the adapter, the standby instruction command for writing the subscriber data stored in the ROM 132 becomes:
The data is sent to the data card according to the instruction of the MPU 131 (step 103). This command is for instructing the data card to start a standby operation for writing subscriber data, and is unique to the data card (generally depends on the manufacturer of the data card).
This command includes a special command that cannot be used by the user, for example, an extended AT unique to a data card manufacturer.
It is preferable to use a command or the like. In the data card receiving this command, the MPU reads the program from the ROM in the control / signal processing unit 23 and executes a standby sequence for writing subscriber data. This subscriber data write standby sequence proceeds to a state in which it waits for a subscriber data write wave of a predetermined frequency, and enters an interrupted state.

In this state, the operator inserts the adapter 1 (see FIG. 4) into which the data card 2 is inserted into the shield box 31 of the writing machine 3 (see FIG. 5A), and puts the shield box 31. After closing (see FIG. 5B), a writing instruction operation is performed on the writing machine 3. As a result, a subscriber data write wave of a predetermined frequency is emitted in the shield box. The standby sequence for writing the subscriber data executed on the data card is continued by receiving the subscriber data write wave, the data card is set to the standby state for writing the subscriber data, and the sequence ends.

When the standby sequence for writing subscriber data ends normally, the data card sends a standby completion response to the adapter, and the MPU 131 of the adapter that has received this response proceeds to the next step (step 10).
4).

The adapter has timer means, which measures the elapsed time from the sending time of the standby command command for writing subscriber data, and when the standby completion response is not returned within a predetermined time (for example, 30 seconds). The MPU 131 sends a standby establishment failure signal to the input / output unit 1
6 to perform error processing for causing the buzzer and / or LED to execute a predetermined operation (step 105). Thereby, forgetting to insert the adapter 1 into the writing machine 3,
The operator can be notified of the standby establishment failure due to other causes. As the timer means, the clock generator 17 for supplying a clock signal to the MPU 131 can be used. After notifying the operator of the error, the MPU 131 operates the switch S as the final step of the error processing.
It is preferable to provide a process for controlling W to cut off the power supply from the power supply unit 14 to the data card.

MPU 13 that has received the standby completion response
1 sends a subscriber data write request command stored in the ROM 132 to the data card (step 106). This command is also composed of a special command such as the above-mentioned manufacturer-specific extended AT command. In the data card that receives this command, the MPU
The program is read from the OM, the subscriber data write sequence is executed, and the subscriber data is written into a nonvolatile memory such as a flash memory by a subscriber data write wave of a predetermined frequency emitted in a shield box of the writer. Is written. When the subscriber data write sequence is completed, the data card sends a subscriber data write completion response to the adapter. In the adapter receiving this response, the MPU 131 sends a write normal end signal to the input / output unit 16 to cause the buzzer and / or LED to execute a predetermined write completion display (steps 107 and 108). At this time, the adapter is present in the shield box of the writing machine, but the operator can confirm the success of writing by sounding a buzzer in the shield box and visually checking the LED through the observation window of the writing machine. As a final step of the normal termination process, it is preferable to provide a process of controlling the switch SW by the MPU 131 to cut off the power supply from the power supply unit 14 to the data card.

On the other hand, if the subscriber data write completion response is not returned within a predetermined time, or if a subscriber data write sequence abnormal end signal is returned from the data card, the adapter outputs a write failure signal to the input / output unit 16. And performs error processing for notifying the adapter operator with a buzzer and / or LED (step 109).
In this case as well, as the final step of the error processing, the MPU
It is preferable to provide a process of controlling the switch SW by 131 to cut off the power supply from the power supply unit 14 to the data card.

[0025]

By using the wireless integrated data card writing adapter of the present invention, a personal computer having a PC card slot when writing public subscriber data to the wireless integrated data card becomes unnecessary.
Further, since the adapter of the present invention can be significantly reduced in size as compared with a personal computer, it can be easily stored in a shield box of a writing machine.
