JPH0360537A - Selective call receiver for radio - Google Patents

Abstract

PURPOSE:To recognize notification without fail by setting time for notifying operation corresponding to the number of times of calling to the same selective call number, which is received beforehand, when its own selective call number is received. CONSTITUTION:When its own call number is received, in a decoder 20, a signal from a waveform shaping circuit 19 is compared with the call number written into a writable read only memory 22 in advance. When both signal and call number are coincident, 1 is added to a counter in the decoder 20 and the time for notifying operation is set corresponding to the contents of the counter. Then, a signal is sent to a notifying means driving and amplifying circuit 23 and a notifying means is driven for the set time.

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 notification means for a radio selective call receiver.

[Prior Art] Conventionally, when a call is received, this type of radio selective calling receiver performs a notification operation for a predetermined period of time using notification means such as ringing, light emission, and vibration.

[Problem to be Solved by the Invention 1] In the conventional radio selective calling receiver described above, the time for the notification operation is predetermined, so if the notification operation stops before the recipient recognizes the notification, the caller has the disadvantage that it must be called many times and cannot be recognized reliably.

SUMMARY OF THE INVENTION An object of the present invention is to provide a radio selective calling receiver that solves the above problems.

[Means for Solving the Problems] In order to achieve the above object, the wireless selective calling receiver of the present invention has at least one selective calling number, and performs a notification operation when receiving its own selective calling number. In the wireless selective calling receiver, the time for the notification operation is set depending on the number of calls to the selective calling number.

[Example 1 Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a radio selective calling receiver according to the present invention.

In the figure, a selective calling signal received by an antenna 17 is amplified and demodulated by a radio section 18. The demodulated signal is converted into a waveform readable by a decoder 20 through a waveform shaping circuit 19. The decoder 20 is operated by a crystal oscillator 21 for clock generation. The decoder 20 uses a signal from the waveform shaping circuit 19 and a writeable read-only memory (Program, ble Read Only).
The call number pre-written in the memory (PROM) 22 is compared, and when the two match, the counter in the decoder 20 is incremented by one, and the notification operation time corresponding to the contents of the counter is set. 28 is a power switch, and 29 is a power source. When the notification operation time is set, the decoder 20 sends a signal to the notification means drive amplifier circuit 23,
Among one or a combination of the speaker 24 as the first notification means, the LED 25 as the second notification means, and the vibrator 26 as the third notification means, FRO
The notification means written in advance in M22 is driven for the set time. The contents of these operations and counters are as follows.
It is reset by pressing the reset switch 27.

FIG. 2 is a flowchart diagram of one embodiment of a wireless selective calling receiver according to the present invention. The wireless selective calling receiver receives its own calling number (step l), and sets the number of receptions to 1.
(step 2), and sets the notification operation time according to the number of times the same number has been received up to that point. There are several possible settings methods, but here we will introduce one of them.
I will explain about one.

When the radio selective calling receiver shown in FIG. 1 receives a called number, if it is the first reception (step 3), the notification operation time is set to t seconds (step 4), and for the second time (step 5).
When , it is extended by α seconds from the first time to (+α) seconds (step 6), and when it is the third time (step 7), it is α from the second time.
Extend the second by (t+α+α・t+2α) seconds (Ste Shiv 8
), the fourth time (step 9) is extended by α seconds from the third time (t + 2α + α = +3α) seconds (step lO)
If it is 5 times or more, extend α seconds from the 4th time (t+3
α+α=t+4α) seconds (step 11).

When the notification operation time is set, the receiver starts the notification operation and operates the timer until the set time (step 12).
). If the notification operation stops after the set time elapses and the timer runs out (step 13), it is determined that the recipient did not recognize the notification, and the call is stored in memory as an unread call (step 14). do. If the reset is performed during the notification operation (step 15), it means that the recipient has recognized the notification, and if there is an unread call, it is deleted from the memory and the number of receptions is reset (step 1.6). If the radio selective calling receiver has a plurality of calling numbers, the same flowchart is used to notify each calling number.

(Effects of the Invention) As explained above, in the present invention, when a selective calling number of one's own is received, the notification operation time is set according to the number of calls to the same selective calling number received previously. Since the time required for the recipient to recognize the notification can be set, this has the effect of ensuring that the recipient recognizes the notification.
