Abstract

PURPOSE:To connect an incoming call to a designated terminal by applying a single subscriber number and a subscriber class showing the group constitution of plural terminals to a subscriber unit provided with plural terminals and dialing a selection code designating each terminal inside the group. CONSTITUTION:When a caller, who originates a call from a CLG 1 and hears a dial tone from an SPCA 2, dials a subscriber number N, at the SPCA 2, it is recognized from the subscriber class of the subscriber number N that a subscriber to be called owns plural terminals, and the input of the selection code of a terminal to be called is pressed. When the selection code of the terminal to be called is received from the CLG 1, at the SPCA 2, the terminal number of the designated terminal to be called is extracted from a terminal number list n21, which is provided by retrieving a terminal number translation list 20 with the subscriber number N, corresponding to the selection code. When the terminal to be called of this terminal number is accommodated in the present station, a central processing unit performs the in-present station connection processing of the CLG 1 to a CLD 41 or CLD 42 and when it is accommodated in the other station, the call is terminated to a CLD 51 by performing outgoing connection processing to a repeater line 6.

In this conventional incoming call connection system, since the incoming call connection control is performed by receiving the dial signal of the telephone number given to each telephone in the group, there are a plurality of types of individuals and companies. If you have a telephone (general telephone, mobile telephone, facsimile terminal, etc.) or if you have multiple telephones installed at multiple locations (home, office, etc.), call each telephone Since there is a number, there is a problem that it is not possible to give a single telephone number to each individual or company.

An object of the present invention is to give a single subscriber number to a subscriber unit having a plurality of terminals and a subscriber class indicating that this subscriber number and one group constitute one group, The caller dials the subscriber number of the called subscriber and the selection code that designates each terminal in the group, thereby providing a subscriber terminal-designated incoming call system that enables incoming connection to a desired terminal. Especially.

[0005]

According to the present invention, in a storage program control type exchange, a single subscriber number for one subscriber who has a plurality of terminals and one group of the plurality of terminals are provided. And a subscriber class for controlling the subscriber number are provided, and the subscriber data is provided with a terminal number list storing the subscriber number and the terminal numbers of the terminals belonging to the group of the subscriber number When the subscriber number and a selection code for designating each terminal are received from a subscriber, the designated terminal number extracted by searching the terminal number list corresponding to the subscriber number with the selection code is translated. Then, a subscriber terminal-designated incoming call system is obtained which is characterized in that the incoming call is connected to the designated terminal.

Further, when the exchange of the stored program control system receives the subscriber number from the caller, it sends either a second dial tone or a message to dial the selection code to the caller. A subscriber terminal-designated incoming call system characterized by urging can be obtained.

Further, when the selection code from the caller is not received before the timing monitoring is started from the time when the second dial tone or the message is sent and the time-out is reached, the representative connection processing or call transfer registered in advance is performed. A subscriber terminal-specified incoming call method characterized by performing processing is obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a flowchart for explaining the operation of an embodiment of the subscriber terminal-designated incoming call system of the present invention, FIG. 2 (a).
FIG. 2 is a system block diagram of a storage program control type exchange system to which an embodiment of the present invention is applied, and FIG. 2B is a diagram showing an example of a subscriber data structure in the main memory in FIG.

Referring to FIG. 2A, a storage program control type exchange system of this application example is a storage program control type exchange (SPCA) 2 and a storage program control type exchange connected by SPCA 2 and a trunk line 6. (SP
CB) 3.

The SPCA 2 accommodates a calling terminal (CLG) 1 and called terminals (CLD) 41, 42, and SPCB 3
The CLD 51 is housed in.

CLG1 is a general telephone, CLD41
The CLD 42 and the CLD 42 are a general telephone installed in the office 4 and a telephone attached to a facsimile device.
Reference numeral 51 is a general telephone installed in the home 5.

Then, the CLDs 41, 42, and 51 are 1
Belonging to one group, a single subscriber number N and a subscriber class for controlling the CLDs 41, 42 and 51 as one group are assigned to this group.

In the SPCA2, a main storage device (not shown) stores subscriber data of the called subscriber (including, for example, the terminal number translation list 20 and the terminal number list n21 shown in FIG. 2B). .

In FIG. 2B, the terminal number translation list 20 is a linkage with the terminal number list for each subscriber number. The terminal number translation list 20 is searched by the subscriber number and the numbers in the terminal number list are searched. obtain. In the figure, the terminal number list n21 of the subscriber number N is obtained.

In the terminal number list n21, selection codes "0", "1", for designating the called terminal from the sender.
The telephone numbers of the CLDs 41, 42, 51 corresponding to "2" are stored.

The operation of one embodiment of the present invention will be described with reference to FIG.

When the caller makes a call from CLG1 (step S1), SPCA2 sends a dial tone from a call register (not shown), as is generally known (S2).

When the caller hears this dial tone and dials the subscriber number N, in SPCA2, the call origination register receives it, and the called subscriber from the subscriber class of the subscriber number N selects one terminal from a plurality of terminals. Recognizing that the subscriber is owned by the group, the second dial tone is sent and the caller is urged to dial the selection code of the called terminal (S4).

If the selection code of the called terminal is not known, in S4, a message (for example, "0" for a telephone call to the office; Dial "1" or dial "2" for home calls.)).

When the selection code of the called terminal is received from the CLG 1 (YES in S5), in SPCA2, a central processing unit (not shown) searches the terminal number translation list 20 by the subscriber number N and searches the terminal number list n21. And obtain this terminal number list n21 with selection codes "0", "1", "2"
(S6), and the terminal number of the designated called terminal is extracted and translated (S7).

When the called terminal is accommodated in the own station from the terminal number translated in S7 (YES in S8), the central processing unit sets CLG1 to the called terminal in the office 4 by a generally known method. In-station connection processing is performed to (CLD41 or CLD42 depending on the selection code) (S9).

When the called terminal is accommodated in another station (NO in S8), the central processing unit performs outgoing / connection processing to the trunk line 6 (S10), and the call from CLG1 is SPCA.
2, it is connected to the called terminal (CLD51) of the home 5 via the relay line 6 and the SPCB3.

In S4, the timing monitoring is started from the time when the second dial tone or the message is transmitted, and when the selection code of the called terminal is not received from the caller before the time-out (NO in S5), registration is performed in advance. A so-called representative connection process using a designated representative terminal number may be performed, an incoming call forwarding process to a registered predetermined terminal may be performed, or an incoming call may be rejected (S11).

The representative terminal number and the call transfer destination terminal number are easily registered by applying a generally known method.

As described above, in this embodiment, the caller dials the called subscriber number N and subsequently the selection code for designating the called terminal, so that the CLG 1 calls the called terminal CLD.
It is connected to a desired terminal among 41, 42 and 51.

[0027]

As described above, according to the present invention, when one subscriber owns a plurality of terminals, a structure is provided in which the subscriber number data of this subscriber is provided with a terminal number list. This has the effect that a person can reach a desired terminal simply by dialing a selection code for designating a called terminal after a single subscriber number.

In addition, by combining the representative connection service and the call transfer service with the subscriber terminal-designated call reception method of the present invention, there is an effect that services for subscribers are remarkably diversified.
