In response to control signals such as “calling number notification” and “display during call”, transmission of a voice call or data communication, reception of a call, and termination can be controlled by operation of the arm-mounted terminal 200 side. In addition to the incoming and outgoing calls and the end of the call, automatic functions such as automatic incoming mail, answer hold and release, call transfer, answering machine operation, and other functions can also be controlled and used by the operation of the wrist-worn terminal 200 similarly.

The control command from the wrist-worn terminal 200 to the wireless modem unit 300 may be transmitted by transmitting a control command such as an AT command and receiving a response code for responding to the control command. 13 to 16 illustrate an example of control by an AT command with reference to the above case. The AT command is a command system used for controlling a modem or a terminal adapter. FIG. 13 is a block diagram showing a concept of control by a command of the wireless communication system 100, and FIGS. 14 and 15 show specific examples of a control command and a response code.

As shown in FIG. 13, the arm-mounted terminal 200
When detecting a predetermined instruction input from the operation unit 230, the CPU 211 generates a command based on the input instruction content, and sends the command to the wireless modem unit 300. The wireless modem unit 300 is the CPU 3 of FIG.
The command recognition unit 321a recognizes the input of the command, and the memory control unit 321b temporarily stores the command in a command buffer in the CPU 321. Also,
The command decoding unit 321c decodes the input command, and the command execution unit 321d controls the RF circuit unit 310 and the baseband signal processing unit 320 according to the content of the decoded command. A control signal and data are transmitted to the wireless base station 110.

The radio base station 110 transmits and receives various control signals and data such as a telephone call or data communication with a transmission destination on the network 120. The radio base station 110 transmits a control signal or data received from a transmission destination of the network 120 to the radio modem unit 300. When the antenna 303 of the radio modem unit 300 receives the control signal or data, the RF circuit unit 310 Signal processing unit 3
20 sends these control signals and data to the command execution section 321d, and the command execution section 321d sends a response code corresponding to the control signal and data to the response code generation section 32d.

When a command is input based on an instruction input from 0 and sent to the wireless modem unit 300 side, the CPU 321 of the wireless modem unit 300
First, it is determined whether a command start code has been input (step S101). If a command start code is input, it is determined whether or not there is further input data (step S102). If the input data is a command end code (step S103; Yes),
The memory control unit 321b determines whether the command buffer in the CPU 321 is empty (step S1).
04), if it is empty (step S104;
Yes), a response code is output from the response code generation unit 321e (step S105). The response code output here is, for example, “4 / ERROR” if an error occurs. Thereafter, when returning to the command input mode again (Step S106; Yes), the process returns to Step S101 and accepts a command input.

If the input data is not an end code in step S103, the memory control unit 321b stores the input data (command) in the command buffer (step S107). If the command buffer overflows due to this storage (step S
108; Yes), and the response code "4 / ERO
R ”is generated and output, and an error message is displayed on the display unit 220 of the wrist-worn terminal 200 (step S10).
9). If the command buffer has not overflowed (Step S108; No), the process returns to Step S120 to accept the next data input.

When the command is input in this way, the commands are sequentially stored in the command buffer, and then the end code is input (step S103; Yes), the command decoding unit 321c reads the entire command line and decodes it. Is started (step S110). Command decryption unit 32
If a mistake is found in the command format in step 1c, an error message is output (step S1).
109). If the format is correct, the command execution unit 321d executes a process according to these commands. The processing executed here is, for example, various settings,
Dialing, automatic reception, data communication, and the like. When the process is executed according to the command, the response code generation unit 3
21e generates a response code according to the processing result, and outputs a response to the wrist-worn terminal 200 side (step S105).
To end the command input mode (step S10
6; No), the process proceeds to a command end process.

Next, the overall processing flow executed on the wireless modem unit 300 will be described with reference to FIG. First, after power is supplied, the CPU 321 initializes various settings of the wireless modem unit 300 (initialization).
