Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an individual selection receiver which, upon receiving a call signal for itself, displays the calling number and information contained in the call signal.

(Prior art) Conventionally, paging operations using individual selection receivers have simply been to call the called party, but recently, they have been used to send information such as messages and commands along with a paging signal.
Various means are available for communicating to the called party through display or synthesized speech.

However, in the operation of individual selection receivers, it is still a system led by the sending (calling) side, and if the called party happens to be unable to answer the call, such as during surgery, someone else will If you ask someone to carry it with you, leave it on your desk, or turn off the power switch, it may be difficult or impossible to receive a call during that time even if you want to receive it on standby (portable reception). This system had the disadvantage of reducing operational efficiency, such as forcing people to

(Problems that the invention attempts to solve) In order to eliminate the above-mentioned problems and reduce the mental burden on the called party, this invention aims to reduce the number of calls received even if the callee is on standby in the so-called "absent state". After the called party's "absence state" is resolved by accepting the previous calls and memorizing them economically,
These memorized caller numbers (multiple numbers) are sequentially displayed by the callee's operation, allowing the caller to be contacted. It is useful for improving system performance and increasing the operational efficiency of the system. This will be explained in detail below.

(Means for solving the problem) In a normal selective calling receiver with a display, when the first call is received, the received contents such as the calling party number and information such as the message are stored. , the memorized contents are displayed in response to the caller's operation, and when the second call is received, the first
It is common to clear the stored contents of the first call and re-store new data such as the calling number and message received the second time. On the other hand, in the case of receiving a call with an answering function, which is a feature of this proposal, the data during normal reception is cut out and only the caller numbers that have been received multiple times are stored. Processing is performed using the same memory capacity. The details will be explained below.

(Operation) If the person carrying the selective calling receiver according to the present proposal happens to go out of the service area due to going out or other reason and is away during that time, he or she will operate the answering button, which is the mode switch of the receiver, and By switching from the normal reception mode to the absentee reception mode and then placing it in a predetermined position, it is possible to receive calls while the user is away.

In other words, in this proposal, when receiving an answering call, the contents to be stored are divided into the calling party number and the message that follows, and each time a call is received, only the calling party number is stored preferentially until the memory capacity is reached. After reaching the number, the old calling number is erased one by one while the new one is memorized.

With this, when the user returns from an outing and operates the display button, he or she can learn a plurality of stored caller numbers, thereby making it possible to contact a call received while the user was away.

In this way, even with the same memory capacity, it is possible to process several times as many called calls during absentee reception as compared to during normal reception, which is economical and allows easy operation. . A more detailed explanation will be given below with reference to FIGS. 1 and 2.

(Embodiment) FIG. 2 shows the frame structure of a calling signal sent from a base unit to each slave unit based on an embodiment of the present invention.
At the beginning of the signal, a synchronization bit code 1, an identification code 2 of the slave receiver to be received (hereinafter abbreviated as ID code), a calling party number 3, and information (data) 4 such as a message are shown.

FIG. 1 shows a related block diagram of a receiver based on an embodiment of the present invention, and first the case of normal reception will be explained.

The transmission signal, which is a calling signal sent from the above-mentioned base unit, is received by the antenna 5 and sent to the receiving circuit 6.
is input. The receiving circuit 6 performs tuning, frequency conversion amplification, detection, etc., extracts the transmitted signal, and sequentially processes the signal starting from the synchronization bit code 1 at the beginning of the signal.

This synchronization bit code 1 is input to a synchronization bit extraction circuit 7, where a bit clock pulse is extracted and outputted to a bit clock generation circuit 8. The bit clock generation circuit 8 generates clock pulses in asynchronous synchronization with the bit clock pulses of the transmission signal based on the input bit clock pulses, and outputs them to the central controller 11 to control the operation timing of each circuit. .

The received signal is also simultaneously supplied to the ID code detection circuit 9 which is the called party number, and the synchronous bit code 1
The ID code 2 inserted next to the ID code 2 is extracted by the ID code detection circuit 9, and the ID code of the receiver that should receive the transmission signal in the identification code is read out and stored in the ID code memory 10. It is compared with the ID code of the receiver, and the result is output to the central control unit 11, which notifies the called party by controlling a buzzer or the like that the call has been received.

If the above matching results match, the subsequent calling party number code 3 is extracted by the calling party identification circuit 12, the gate circuit 14 is opened under the control of the central controller 11, and the calling party number code 3 is memory 15
is stored on the first page of . Subsequently, if data 4 exists, it is extracted by the data identification circuit 13, the gate circuit 14 is opened under the control of the central controller 11, and the data is stored in the second to nth surfaces of the memory 15.

For example, if the capacity of each side is 8 characters, and the 4th
If there is a page, the first page stores the calling number, and the second to fourth pages store data of up to 24 characters.

At this time, as mentioned above, the called party knows that he/she has been called by a buzzer or the like, so he/she operates the display button 17 and the information is stored in the first page of the memory 15 based on the command from the central control unit 11. Caller ID code 3
is first read out and displayed on the display device 11. Furthermore, when the display button 17 is pressed, the second page to
The data 4 stored on the fourth screen is sequentially displayed.

Next, the case of answering calls, which is a feature of the present invention, will be explained in detail.

As mentioned above, if you want to use answering mode,
When the answering button 18 is operated, the central control unit 11 drives the inhibit circuit 19 to lock the data identification circuit 13, and when receiving subsequent calls, the caller number code 3 is set. For example, each time a call is received, it is stored in the first to fourth surfaces of the memory 15 through the gate circuit 14, as described above.
It is stored sequentially.

In other words, in the case of answering calls, by storing only the calling number to know who has contacted you, in this embodiment, four times as many calls can be received without increasing the memory capacity. This is economically possible, and calls can be processed by sequentially contacting the calling party when the called party returns from an outing. The decoder unit mentioned in the scope of the utility model registration claim includes the part of the ID code detection circuit 9 that detects the called party number (ID code), the calling party number identification circuit that detects the calling party number, and the part that detects the called party number (ID code). Refers to the data identification circuit to be detected.

What is the detection circuit mentioned in the scope of the utility model registration claim?
This is the part that detects whether the called party number detected by the ID code detection circuit 9 is the same as its own number.

(Effects of the Invention) Since the present invention allows efficient use of memory capacity, it is possible to receive messages from many callers without fail.

Furthermore, compared to its functions, the individual paging receiver can be constructed more economically.
