Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvements in wireless communication devices.

[0002]

2. Description of the Related Art As a wireless communication device, a part of which is detachable from a main body including a wireless circuit is known, for example, those disclosed in JP-A-64-54825 and JP-A-3-6346. ..

For example, Japanese Unexamined Patent Application Publication No. 64-54825 relates to a radio selective calling receiver. As shown in FIG. 11, a reception signal received by an antenna 1 is passed through a radio circuit 2 and a waveform shaping circuit 3. It demodulates and demodulates it, and compares it with the individual selection code written in advance in the writable ROM 5 in the decoding circuit 4. The decoding circuit 4 drives the notification circuit 6 to cause the speaker 7 to ring only when the two match. The writable ROM 5 is detachable from the radio selective calling receiver body 8.

The one disclosed in Japanese Utility Model Laid-Open No. 3-6346 relates to a paging receiver, and as shown in FIG.
The signal received by the antenna 11 is demodulated by the receiver 12 and supplied to the decoder 13. The decoder unit 13 decodes the demodulated reception signal with the data from the ID-ROM 14, and if the reception signal is transmitted to itself, sends the call detection signal and the received message data to the CPU 15 and The switch 16 is turned on and off. The switch 16 is controlled to be turned on and off so that the power supplied from the power supply 17 to the receiver 12 via the switch 18 is turned on and off. The ROM card 19 is detachably attached to the main body 20 and fixedly stores reception control data for receiving the information providing service. The message memory 21 is divided into a plurality of memory areas, and the received message is stored in different memory areas depending on the type of message. The switch circuit 22 includes a large number of switches, and sends a switch input signal corresponding to the operated switch to the CPU 15. LED driver 23 is a CPU
Under the control of 15, the LED 24 blinks to notify that the paging receiver has been called. The buzzer driver 25 operates the buzzer 26 under the control of the CPU 15.
Is driven to give various notifications such as call notifications. The display unit 27 receives the control of the CPU 15 and displays the received message and the like stored in the message memory 21. The CPU 15 controls each unit of the receiver according to the program written in the built-in memory 151. For example, in order to reduce reception mistakes on the receiver side, the same contents for a predetermined time,
For example, there is control in a repeat call that is retransmitted after 60 seconds, time management when determining whether or not data of the same content is received within a predetermined time, check of received content, control of each part according to the determination result, etc. CPU15 will do.

[0005]

However, in the former case, for example, if the length of the individual selection code is changed, the hardware of the decoding circuit 4 inside the receiver body must be set in order for the receiver to cope with this. However, there is a problem that such a change cannot be executed on the user side.

In the latter case, the control of each part is performed by the CPU.
Since it is performed according to the program written in the memory 151 built in 15, the program of the memory 151 is changed when the communication procedure is changed, such as changing the repeat call time limit from 60 seconds to 120 seconds. Therefore, there is a problem that the CPU 15 needs to be replaced, and also in this case, there is a problem that it cannot be executed on the user side.

Therefore, the present invention is intended to provide a wireless communication apparatus capable of easily coping with changes in communication systems such as communication procedures and interfaces on the user side.
