[0003]

According to the conventional telephone exchange method, it is impossible to make a direct call unless the caller has a telephone number of which the caller is aware in advance. Recently, however, the use of radio pager portable receivers called so-called pagers (hereinafter referred to as “portable receivers”) has become widespread, and if the other party has it, he / she can easily call it even when he is out . However, even if the other party is called by this mobile receiver, the call cannot be made directly, and in order to make the call, the mobile receiver is notified of the telephone number information to be answered, and the answering call from the other party is received. There must be. Therefore, if there is no telephone capable of receiving at the location of the caller, even if the other party has a portable receiver, it is not possible to call and make a direct call. The present invention has been made in view of such circumstances, and an object thereof is to provide a telephone exchange that enables direct calls between public telephones when both the caller and the other party are out of the office. To provide a method.

[0004]

[Means for Solving the Problems] In a telephone exchange device,
An incoming call is made to a predetermined one of the plurality of telephone lines accommodated in it, and the caller (caller) indicates his own identification number and the identification number of the person who wishes to make a call, and then the line is disconnected. By waiting, the portable receiver corresponding to the designated identification number is notified of the telephone number information to be answered, and the answering call from the opponent is received on the predetermined line. Then, in cooperation with the incoming call of the answering call from the other party, the telephone number information to be answered is notified to the portable receiver corresponding to the identification number of the caller, and the answering call from the caller is received on a predetermined line. I chose Through the above procedure, when there is an incoming call from the caller, this line is connected to the line of the other party who has received the call earlier.

[0005]

As a result of the above measures, even if there is no receiving telephone at the location of the caller, the nearest telephone can be set to the telephone number notified via the portable receiver. The caller's line and the other party's line are connected by responding using.

An embodiment of the present invention will be described below.
In this embodiment, the present invention will be applied to a telephone exchange device accommodating three subscriber lines of existing subscriber telephone lines. FIG. 1 is a flow chart showing an outline of a series of processing procedures of this embodiment. It should be noted that the telephone exchange device has, of course, a function of connecting any two lines out of a plurality of lines accommodated therein and a function of receiving and transmitting for each line. The process was done manually. As the identification numbers of the calling party and the other party, the calling numbers of the portable receivers possessed by each may be used, or separately, for example, a membership number which is set and registered as a pair with the calling number of the portable receiver beforehand. However, when using membership numbers, you cannot use duplicate numbers.
Lines were divided into one for calling and two for responding. Monitor ringing indication and incoming call detection. Each line returns to this state when the processing for that line is completed. When a call instruction is detected, the call number of the portable receiver corresponding to the identification number indicated by the idle line is called, the wireless call base station is connected, and then the response is displayed on the display window of the portable receiver. A dial signal for displaying the telephone number of the responder line is transmitted as the telephone number information to be transmitted, and the process ends. When an incoming call is detected, it is determined whether the incoming call line is for a caller or a responder. When an incoming call arrives at the caller line, the caller is asked to identify himself. Next, the identification number of the person who wants to make a call is obtained, and this is recorded as a pair with the identification number of the caller. Based on this, a calling instruction is given and then the process ends. On the other hand, when there is an incoming call on the line for the responder, the caller is asked to identify his / her own identification number and this is collated with the previously recorded identification number. If there is a match and there is a partner identification number paired with that identification number (in this case, the identification number of the caller), the call instruction is given based on that partner identification number, and then this identification number is used. The other identification number recorded in pair with this identification number (in this case, the identification number of the responder) is erased. After this, the line is monitored because it is waiting for an incoming call from the caller. When the line is disconnected, the record of the identification number is deleted and the process ends. By deleting the unnecessary identification number in this way, it is determined whether the incoming call thereafter is a valid answer call from the caller or an invalid call. If there is a match and there is no partner identification number paired with the identification number, this is a response from the caller, so this line and the other line with the same identification number are connected. Thus, a direct call between the calling party and the other party is realized. When disconnection of both or one of the lines is detected by the end of the call, the line connection is released, the record of the identification number is erased, and the process ends. The embodiments of the present invention have been described above. Although this embodiment is a simple manual type, a recent telephone exchange apparatus mainly uses an electronic circuit, and since a voice response system and the like are widespread, various telephone exchange apparatuses are applied to them. Various implementations are possible.

[0007]

According to the present invention, the caller calls a predetermined telephone number, indicates the identification numbers of the self and the other party, and then temporarily disconnects the line and waits. Notify the telephone number information to be answered, receive the answering call from the other party on a predetermined line, and in conjunction with this incoming call, notify the caller's portable receiver of the telephone number information to be answered,
This is a telephone exchange method in which when a response call from a caller arrives at a predetermined line, this is connected to the line of the other party who has received the call first. Therefore, according to this telephone exchange method,
Direct calls can be made between public phones when they are out of each other. Also, since the caller indicates the identification numbers of himself and the other party and then disconnects the line and waits, there is no need to hold the line and wait until the answering call from the other party arrives, so it is useless. It is economical without increasing the price.
