Furthermore, automatic exchanges that accommodate general telephones can identify the telephone number assigned to a calling telephone from the housing position of the telephone. In addition, automatic switching equipment that accommodates telephones installed in mobile devices such as cars can identify the caller's telephone number by transmitting its own telephone number together with the calling signal when a mobile telephone makes a call. You can.

fcl Prior Art and Problems FIG. 1 is a diagram showing an example of a conventional automatic switching system. In FIG. 1, it is assumed that mobile telephone MA is housed in exchange EXA, mobile telephone MB is housed in exchange EXB, and the users of mobile telephones m and MB are absent. When mobile telephone MA makes a call to mobile telephone MB in such a state, central control unit OCA of exchange EXA calls mobile telephone MB.
In addition to selecting a route to the exchange EXB that accommodates
A call control memo + JCM is set in the main memory device MMA, and timing information t is initialized. From now on, timing information t
is updated over time until the mobile telephone MB responds. Exchange EXB also connects mobile telephone M using a known method.
I select B, but since the user is not present, there is no response for a while. When the timing information in the call control memory CM reaches a predetermined time, the central controller CCA determines that the mobile telephone MB is absent, releases the route to the exchange EXB, and transfers the mobile telephone MA to the voice response device ARA. Connect to. The voice response device ARA transmits a message to the mobile telephone MA informing it of the absence of the called party. The user of mobile telephone MA makes repeated calls to mobile telephone MB until the user of mobile telephone MB returns to the automobile and answers the call from mobile telephone MA.

As is clear from the above explanation, in conventional automatic exchanges, mobile phone MA makes a call to mobile phone MB while the user is away, and when the user of mobile phone MB returns to the car,
There is a drawback that calls must be made repeatedly until the incoming call can be answered.

(dl) Purpose of the Invention The purpose of the present invention is to eliminate the drawbacks of the conventional automatic switchboards as described above, and to make it possible to connect to a caller who receives a call while the called party is absent, without having to make repeated calls from the caller. The goal is to realize the means to do so.

(el) Structure of the Invention The purpose of this invention is to provide an automatic exchange equipped with a speed dial function and a caller telephone number identification function, in which if the called party who is currently calling does not answer within a predetermined time, the called party This is achieved by storing the calling party's telephone number in correspondence with a predetermined abbreviated number in the abbreviated dial registration area corresponding to the person, and connecting to the calling party when the called party makes a call using the abbreviated number. be done.

That is, in the present invention, the telephone number of the caller who received the call while the caller was absent is stored together with a predetermined abbreviated number in the abbreviated dial registration area corresponding to the called party. Therefore, when the called party later makes a call using the predetermined abbreviated number, the caller is connected.

([1 Examples of the invention An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram illustrating a missed call telephone number storage method according to an embodiment of the present invention. Note that the same reference numerals indicate the same objects throughout the figures. In FIG. 2, it is assumed that mobile telephone MA sends its own telephone number Na to exchange EXA together with a calling signal when making a call. In addition, the mobile phone MB is equipped with a speed dial function and is connected to the affiliated exchange EXBO.
Unique speed dial registration area AM in main memory MMB
b, and the telephone number of the called party to whom the speed dial call is to be made can be registered together with the corresponding speed dial number. When mobile telephone MA makes a call to mobile telephone MB which is currently absent, central control unit OC of exchange EXA
A initializes the timing information @t in the call control memory CM, stores the calling party's telephone number Na and the called party's telephone number Nb, and selects a route to the exchange EXB. The exchange EXB calls the mobile telephone MB as described above, but if the mobile telephone MB does not respond for a predetermined period of time, the central control unit OCA detects that the timing information [in the call control memory CM] has reached the predetermined time and calls the mobile telephone MB. connecting the MA to the voice response device ARA and transmitting a message to the mobile telephone MA notifying that the called party is absent;
Telephone numbers Na and Nb are extracted from the call control memo IJCM and sent to the exchange EXB via the outgoing sender trunk O5A.

The exchange EXB, which has received the telephone numbers Na and Nb, stores the telephone number Na in an area corresponding to a predetermined abbreviated number (for example, 10) of the abbreviated dial registration area AMb corresponding to the mobile telephone MB in the main memory MMB. . After the mobile phone MA that listened to the message from the voice response device ARA is restored, the user of the mobile phone MB returns to the car and
The predetermined abbreviated number (10) to check for incoming calls while you are absent.
When you make a call using
B is speed dial registration area A corresponding to mobile phone MB
Mb, the telephone number Na stored corresponding to the abbreviated number (10) is extracted and transmitted to the voice response device ARB, and the mobile telephone MB is connected to the voice response device ARB. The voice response device ARB transmits a message to the mobile telephone MB notifying that the telephone with the telephone number Na that received the call while the mobile telephone MB is absent will be called. Further, the central control unit CCB selects a route leading to the exchange EXA to which the mobile telephone MA belongs, connects it to the outgoing sender trunk O5B, sends the telephone number Na to the exchange EXA via the outgoing sender trunk O3B, and then connects the route to the exchange EXA to which the mobile telephone MA belongs.
