Description

[Detailed description of the invention] The present invention is an individual call receiving device that allows a caller to dial a specific number using one of multiple telephones connected to an automatic exchange, by radio or guided radio, etc. (a so-called pager), and the called party carrying the pager dials a specific number and his or her own pager number on a nearby telephone, thereby connecting the calling party and the called party. This invention relates to an automatic call connection device that enables telephone calls.

In such devices, conventionally, when connecting a telephone to an automatic call connection device via an automatic switchboard, in order to distinguish between dialing contents when calling and dialing contents when answering,
Separate numbers are used for the calling specific number and the answering specific number, which means that extra telephone lines are required.

A conventional device will be briefly described below with reference to the drawings.

FIG. 1 is a basic block diagram of a conventional system in which a caller hangs up and waits.

When a caller dials a specific number, e.g. 8, on a telephone set 1 connected to an automatic exchange 2, the telephone set 1 is connected to a calling counter 6 of an automatic call connection device 2', and the number of dials subsequently dialed. count.

The code conversion device 7 converts the counted dial number into a code and emits radio waves through the transmitter 3 and the antenna 5.
Call pager 4.

At the same time, based on the information from the calling counter 6, the number of the pager to be called is stored in the storage circuit 8a of the storage device 8, and the telephone number of the caller to be dialed subsequently is stored in the storage circuit 8b.

After dialing, the caller hangs up and waits for a response.

When a called party carrying a pager dials a specific answering number, for example 7, and his or her own pager number on a nearby telephone 9, the caller is connected to the answering counter 10 of the automatic call connection device 2'. It will be remembered there.

The comparator 11 compares the memory contents with the memory contents of the memory circuit 8a, and when the two match, the impulse sender 1
2, a dial signal is sent to the automatic exchange 2 through the telephone communication circuit 13 based on the contents stored in the memory circuit 8b, and the caller is called.

When the calling party picks up the handset of the telephone set 1, the calling party and the called party can communicate via the communication circuit 13 and the automatic exchange 2.

The need for two types of specific numbers for the automatic switchboard in such a system is a great disadvantage.

For example, in the case of an automatic switchboard with four-digit extensions, the use of two one-digit special numbers would result in a total of 2000 unusable telephone numbers.

In general private automatic exchanges, the first digit 0 is used for the central office line or outside line, and 9 is used for calling the attendant.
Numbers that can be used for extension telephones are 1 x x x (1
000 series) to 8 x x x (8000 series).

At this time, if 8 and 7 are used as the specific numbers, only numbers 1xxxx to 6xxxx can be used for extension telephones.

As a countermeasure, make the specific number two digits, for example 88.
There is also a method of using 87 as the specific number for calling and 87 as the specific number for answering, but this method reduces the number of dialed digits for the caller, even though it is better for the user to dial as few digits as possible. This is not very desirable since it will increase by one order of magnitude.

The present invention seeks to remedy the above-mentioned drawbacks and provide an automatic call connection device which operates with only one single digit identification number, i.e. the same calling identification number and answering identification number.

However, in this invention, the first digit of the pager number and the first digit of the telephone number need to be different numbers, but since the number of pagers is small compared to the number of telephones in use, this is not possible. It is extremely easy to plan such numbers.

For example, the telephone numbers are 1xxxx to 7xxxx, and the pager numbers are only 8xx (800 series).

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 2 is a block diagram showing an embodiment of the present invention.

In the figure, 2'' is an automatic call connection device according to the present invention, and parts corresponding to those in FIG. 1 are given the same reference numerals.

The automatic exchange 2 may be a step-by-step type, a crossbar type, or an electronic type.

Now, a case will be described in which the caller calls the pager 4 having the number 890 using the telephone 1 having the telephone number 1234.

When the caller dials a specific number, for example 8, the caller is connected to the auxiliary storage circuit 14 through the automatic switchboard 2.

The auxiliary storage circuit 14 is a type of buffer register, and is capable of storing the total number of digits, eg, 7 digits, including the number of digits of a telephone number, eg, 4 digits, and the number of digits, eg, 3 digits, of a pager number.

When the telephone set 1 is connected to this auxiliary memory circuit 14, returning the secondary dial tone etc. is performed by the communication circuit 13.
This can be done by using , but since it is not directly related to the present invention, the explanation will be omitted.

When the caller subsequently dials his telephone number 1234 and the pager number 890 he wishes to call, 1234890 is stored in the auxiliary storage circuit 14.

It goes without saying that this operation is not performed only by the dialing method, but may also be directly stored using codes, but here, the explanation will proceed by taking the dialing method as an example.

When a series of dials by the caller is completed and a certain period of time has passed, the determination circuit 15 identifies the first digit of the number stored in the auxiliary storage circuit 14 and determines whether the dial is for a call or a response. Determine what is for.

As mentioned above, for example, the phone number is 1××× to 7×××,
If you set the pager number as 8XX, it will be stored as 1234890 when you call, so the first digit will be 1.
When responding, 890 is stored as described later, so the first digit is 8.

Therefore, when the first number is other than 8, the determination circuit 15 determines that it is a call, operates the gate circuit 16, and transfers the entire contents of the auxiliary memory circuit 14 to the main memory circuit 8.

The main memory circuit 8 includes a memory circuit 8a for pager numbers.
and a telephone number storage circuit 8b, each of which is stored separately, so if a memorization completion signal etc. is sent back to the caller,
The caller can hang up and wait.

Subsequently, the contents of the pager number storage circuit 8a are converted into a code by the code conversion circuit 7, and the pager 4 is called through the transmitter 3 and antenna 5.

When the called party dials the specific number 8 in the same manner as described above using a nearby telephone set 9 connected to the automatic exchange 2, it is connected to the auxiliary storage circuit 14 through the automatic exchange 2, and then the called party When the user dials his own pager number, for example 890, 890 is stored in the auxiliary storage circuit 14.

After a certain period of time after the dialing of the called party is completed, the first digit of the number stored in the auxiliary storage circuit 14 is determined by the determination circuit 15.

If the first digit is 8, the pager number is stored, so the determination circuit 15 determines that it is a response, operates the gate circuit 17, and stores the pager number in the main memory circuit 8. Contents of memory circuit 8a and auxiliary memory circuit 14
The contents of the first three digits of are compared by the comparator 11.

In this case, it is already known that the first digit number of the auxiliary memory circuit 14 and the first digit number of the pager number memory circuit 8a in the main memory circuit 8 are the same. The comparator 11 may compare only two digits.

When the two match, the impulse sender 12 is operated, and based on the contents of the telephone number memory circuit 8b in the main memory circuit 8, a dialing signal is sent from the subscriber line to the automatic exchange 2 via the telephone communication circuit 13. Ring the telephone 1 to call the caller.

When the caller lifts the telephone 1, the telephone circuit 13,
A calling party and a called party can communicate via the automatic exchange 2.

In the above, it has been explained that the operation of the determination circuit 15 is activated after a certain period of time has passed after the completion of dialing. It is also possible to set the operation start time.

Note that the determination circuit 15 sets a predetermined number, for example, and compares the number with the first digit number of the auxiliary memory circuit 14, and when they match, the gate circuit 16 or 1
7 can be easily manufactured by configuring it to operate.

As explained above, according to the present invention, in an automatic call connection device that calls a small number of pagers compared to the number of telephones, only one number is required as the specific number for the pager, so it is possible to use the conventional method. There are more numbers that can be used on telephones compared to .

In particular, in hotels, etc., the first digit of the phone number should be set according to the floor number (1st floor...1×××, 2
Since there are many numbering plans such as floor...2×××,...), there is only one type of specific number used for automatic pager call connection, that is, the number of the first digit. It is very effective to do so.

Moreover, since the pager specific number is only one digit, compared to the above-mentioned two-digit number, an automatic switching machine can be used with two digits.
There is no need to modify the automatic switching equipment for use with the digits, and therefore the device according to the present invention can be connected like an adapter without modifying the automatic switching equipment at all, so it is particularly useful when adding this equipment to an existing automatic switching equipment. It's advantageous.
