JPH01170132A - Radio selection call receiver - Google Patents

Abstract

PURPOSE:To lower the singing output of an address informing singing and reduce a noise by providing a first communicating means to inform a called fact and a second communicating means to inform which number the calling number is among plural individual selection call signals. CONSTITUTION:When the calling number of its own is received, the calling number of an unread call in a memory is checked. When the check does not coincide, an ordinary informing singing is generated, and when the check coincides, a repeat call singing is generated. After the singing is generated, when a t-second timer is started and a reset switch 207 is pushed, the singing output is lowered by the degree of 10dB, and the address informing singing is generated. When the t-second timer is timed out before the reset switch 207 is pushed, such an address call is made into the unread call and stored into the memory. When the address informing singing is generated, an x-second timer is started.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radio selective call receiver, and more particularly to a reporting means for a radio selective call receiver.

[Prior Art 1] Conventionally, the alert reporting means of this type of radio selective calling receiver forms a plurality of sound patterns by different intermittent periods of the sound in correspondence with a plurality of call numbers. When a certain calling number is received, a notification operation is performed using a ringing pattern corresponding to the calling number.

[Problems to be Solved] The reporting operation of the conventional radio selective calling receiver described above simultaneously performs calling address reporting.

For this reason, during normal reporting operations, the system is designed to emit a sound of 75 dos, P, 1 or more at a distance of 30 cm from the receiver, so as not to be affected by surrounding noise. In a quiet place, it can be quite loud.

However, since this reporting operation also serves as a calling address notification, the reporting operation cannot be stopped until the calling address can be identified.

Therefore, in the conventional reporting operation, as the number of calling addresses increases, the time required to identify the calling address also increases.
There was a problem in which a loud sound could be heard for several seconds.

The present invention has been made in view of such conventional problems, and its purpose is to realize a wireless selective calling receiver that can be used in any environment without bothering people around it as much as possible. be.

[Means for Solving Problems] In order to achieve the above object, the present invention provides a wireless selective calling receiver having at least two types of individual selective calling numbers, which includes: a first notification means for notifying that the receiver has been called; and second reporting means for notifying which of the plurality of individually selected calling numbers is the calling number.

[Example] Next, preferred embodiments of the present invention will be described based on the drawings.

FIG. 2 shows a preferred example of a radio selective call receiver according to the present invention.

In the figure, 201 is an antenna, 202 is a radio section, 2
03 is a waveform shaping circuit, 204 is a decoder, 205 is RO
M part, 206 is a crystal oscillator, 207 is a reset switch, 208 is a speaker drive circuit, 209 is a speaker, 21
0 power switch and 211 represent batteries, respectively.

The radio signal received by the antenna 201 is transmitted to the radio unit 2
After being amplified in step 02, it is demodulated. The demodulated signal is converted by a waveform shaping circuit 203 into a waveform that can be read by a decoder 204.

The decoder 204 uses a writable read-only memory (
Programmable-Read Only Mem
ory; P ROM>Compares the own calling number written in advance in 205 with the signal from the waveform shaping circuit 203.

When the two match, a ringing signal is supplied to the amplifier 208 to notify the user of the call, and the speaker 209 is driven. The reset switch 207 stops the sound, etc. A crystal oscillator 206 is a clock generating oscillator that operates the decoder 204.

A characteristic feature of the present invention is that the sound for notification operation and the sound for notification of the calling address are separated, and after the sound for the notification operation is stopped, the sound for notification of the calling address is started. The reason is that we have provided a means for this to occur.

FIG. 1 shows a flowchart showing the operation of the receiver according to this embodiment.

When the wireless selective calling receiver receives its own calling number (
101), and the calling number of the unread call in the memory is verified (102).

If the comparison does not match, a normal notification tone having the pattern shown in FIG. 3(1) is generated (104).

If the comparison matches, a repeat call tone having the pattern shown in FIG. 3(2) is generated (105).

The second timer is started after the sound is generated (106), and when the reset switch (207) is pressed, the sound output is reduced by about 10 dB and the address notification sound as shown in Fig. 3 (3) is generated (108). .

If the L second timer times out (109) before the reset switch 207 is pressed, this address call is stored in memory as an unread call (110).

To generate the address notification sound (108), to start the X second timer (111)L, to reset the switch (20)
7) is pressed or <112> or the X seconds timer times out (113), the address notification sound is stopped (114), and the call number detection operation is performed again (101).
to move to.

[Effects of the Invention] As explained above, the present invention separates notification sound and address notification sound and reduces the sound output of the address notification sound, so that the owner of a wireless selective calling receiver can Even in the environment, the receiver can be used without bothering people around you as much as possible.
