Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radio selective call receiver that includes a built-in synthesizer and is capable of receiving a plurality of channels by setting channels or the like.

[Conventional technology]

Conventionally, in this type of radio selective calling receiver with a built-in synthesizer, the local oscillator is configured with a synthesizer, and by changing the oscillation frequency of this synthesizer, it is possible to receive different channels. In this case, a reception channel is set in advance in a ROM or the like in the receiver, and by driving the synthesizer based on the set channel, the receiver can receive the channel. The receiving channel can be easily changed by changing the channel set using a ROM writer or the like.

On the other hand, in conventional wireless selective calling receivers, several reception areas are registered in the receiver, and when the receiver user moves to a registered area, the wireless selective calling receiver There has also been proposed a wireless selective calling receiver that can receive signals in multiple areas by calling a service company and registering the location.

[Problems to be Solved by the Invention] In the conventional radio selective calling receiver with a built-in synthesizer described above, maintenance such as changing the receiving channel can be easily performed by changing the channel set in the ROM etc. using a ROM writer etc. I can do it. However, for those carrying radio selective calling receivers, it is only RO.
Since it is only possible to receive channels set to M, there is no advantage to having a built-in synthesizer. Rather,
On the other hand, there is a problem in that battery life is shortened due to increased current consumption to operate the synthesizer.

Furthermore, even in wireless selective calling receivers that can receive data in multiple areas, it is necessary to register the receiving areas in advance, which is cumbersome and, at present, few people use the service.

Another problem is that it is not possible to respond quickly when a service is temporarily used at a destination.

The purpose of the present invention is to solve such problems, to effectively utilize synthesizers, and to provide temporary services, etc. at a moving destination.
It is an object of the present invention to provide a radio selective calling receiver with enhanced utility value.

[Means for Solving the Problems] The wireless selective call receiver of the present invention includes means for acoustically coupling and identifying a control signal sent from the outside to the wireless selective call receiver with a built-in synthesizer; and means for writing a new reception channel code into the storage means based on the identified control signal.

In this case, the control signal may be configured to be sent as a PB multiple signal using a telephone line, identify this PB multiple signal, and write the corresponding receiving channel code in the storage means.

Further, the first reception channel code written in the storage means and the second reception channel code newly written in the storage means are configured to be selectively read out by operating a switch. Good too.

[Operation] According to the present invention, by storing and registering a new reception channel 7 channel code based on the received control signal, it is possible to receive the line frequency based on the reception channel code using the synthesizer means. By registering the location of your portable receiver, you can receive services in any area.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block circuit diagram of an embodiment of the wireless selective calling receiver of the present invention. In the figure, a radio signal received by an antenna 101 is input to a radio section 102 and demodulated. The demodulated signal is converted by the waveform shaping circuit 103 into a digital signal that can be read by the decoder section 104. The decoder unit 104 compares its own calling number pre-written in the electrically rewritable non-volatile memory EEPROMI O5 with the signal from the waveform shaping circuit 103, and when the two match, it outputs a message signal following the calling number. receive. Then, to notify that there is a call, a sound signal is supplied to the amplifier 110 to drive the speaker/microphone 112, and at the same time, a message signal is supplied to the LCD (liquid crystal) driver 108, and the message contents are displayed on the display section 109. indicate.

When calling this receiver, a call is made using a calling number registered in the Tokyo area. Then, the data is transferred from the radio selective calling receiver exchange in the Tokyo area to the exchange in the Osaka area, and a call is made using a predetermined channel and call number in a predetermined area.

Furthermore, when the user returns to the home area from the out area, the user notifies the service company that the user has returned to the home area and registers the location.

Then, the receiver is set to the registration mode (604), and the mode selection switch 115 is pressed while pressing the memory scroll switch 114 (616). Then, the receiver responds to this and switches from the out-area setting to the home area setting (617). Thereafter, the carrier puts the receiver in read mode, confirms that the "Home J" symbol on the display section lights up, and completes the registration to the home area.

In addition, if you accidentally switch to home area mode while in the out area, you can return to out area mode.
