Abstract

PURPOSE:To reduce the number of the digits of a sub-address set by a caller by using the corresponding abbreviated dialling information as the address information of an incoming terminal when an abbreviated dial special number is added to the incoming sub-address of the call setting message received from a public network. CONSTITUTION:The title system is provided with an address registering means 1 to register a transmission address to a PBX beforehand and an address information registering means 2 to register the abbreviated dial information corresponding to the transmission address registered at the transmission address registering means 1. A control part (CC) 3, when the abbreviated dial special number is detected from the incoming sub-address of a call setting message received from a public line network, reads the abbreviated dial information corresponding to the transmission address and uses as the address information of a reception terminal. Thus, the number of the digits of the incoming address set by the caller can be reduced.

Here, ``71J indicates the PBX number, ○J indicates the public line access number from the PBX again, that is, the public line network access g#, r062341111'' indicates the public line N
The other party number of T2 and [031 indicate the extension number (terminal sub-address).

When PBX-A receives the call setup message shown in (a), it abandons the Kaya address since it is no longer in use, analyzes the information on the @Nub address, and connects it to the public line via the 3X network. KW recognizes that the access is from the network. Then, send the information of this destination subaddress to the PBX number (71),

The public line network NT2 performs (d
), the corresponding terminal TEB3 is called, and the terminal TEB3 responds, thereby enabling communication between the two terminals TEA1 and TEB3.

[Problem to be Solved by the Invention 1] By the way, in such a communication system that performs communication via a public line, a private line, and a public line, the number of digits of the called subaddress set for calling is large, and the operation is complicated. There is a problem in that the number of digits in the destination subaddress is likely to be insufficient.

The present invention has been made in view of such problems, and provides a speed dial function to a specific subscriber.
The purpose is to reduce the number of digits in the subaddress set by the caller.

[Means to solve the problem] FIG. 1 is a diagram showing the principle of the system of the present invention.

In the figure, reference numeral 1 denotes address registration means for registering a calling address in the PBX in advance, and address information registration means 2 registers speed dial information corresponding to the calling address registered in the calling address registration means 1.

Reference numeral 3 designates a control unit <CG) which performs network control in response to the outputs of the registration means 1.2, and 4 a network controlled by the control unit 3.

[Operation] In the system shown in the figure, it is detected whether a speed dial special number is added to the destination sub-address of a call setup message received from the public network a), and if this speed dial special number is added, it corresponds to the calling address. Use the speed dial information to be used as the address information of the destination terminal (b)
. In other words, the P[3X is prepared in advance with the calling address received from the public line network and the corresponding speed dial information, and the PBX extracts the speed dial special number from the destination subaddress of the call setup message received from the public line network. If detected, speed dial information corresponding to the originating address is successively output and used as address information for the destination terminal. Therefore,
According to the present invention, there is no need to set a destination sub-address for a long time.

[Example] Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a conceptual diagram of the configuration of a communication system that implements the method of the present invention. In the figure, parts corresponding to those in FIG. 6 are designated by the same reference numerals.

The PBX-A is provided with a memory MU that stores a first table TBL1 that associates originating addresses with pointers, and a second table TBL2 that associates pointers of the first table with speed dial information. In addition, writing and reading of this memory, PBX-A/PBX-
A control circuit CC is provided to control between 8 and 8.

FIG. 3 is a diagram showing an example of the first and second tables TBL1 and TBL2 stored in the memory MU.

In the first table TBL1, a pointer corresponding to the originating address (also called originating ID, eg 7703333) is predetermined for each originating address. This pointer indicates the start address of the part in the second table TBL2 where the speed dial information assigned to the caller ID corresponding to each pointer is stored.

In the communication system configured as described above, the speed dial method of the present invention will be explained as follows.

Here, the terminal TE connected to the public network NTI
This is a case where AI communicates with terminal T[03 connected to PBX-B via public line network N2.

The process from terminal TEA1 making a call to PBX-A receiving call setup information is the same as the conventional process.

FIG. 4 is a flowchart showing the subsequent operation in JA when the PBX-A receives call setup information, and FIG. 5 is a conceptual diagram showing the state of information on the line.

The call setup information received by PBX-A includes the originating address and destination address (7772222), as shown in Figure 5(a).
and a spring subaddress (118). Here, the first "11" of the called sub-address is a number indicating that it includes a shortened special number, and the number "8" that follows it is the eighth number of the speed dial information assigned to this terminal. This is for selecting address information.

When PBX-A receives call setup information as shown in (a) via the public network NTI, it abandons the destination address, which is its own selection number, and first determines whether there is an abbreviated special code in the destination subaddress. (Step 1). If there is no shortened special number, normal call connection processing is performed. Also, it is determined whether the first table TBL1 contains the originating address of the received call setting information (step 2), and if not, a call abandonment process is performed.

On the other hand, if it is determined in step 1 that there is an abbreviated special number in the destination sub-address and the originating address is in the first table TBL1, then the first table TBL1
The abbreviated address information located at the address of the value obtained by adding the parameter (8) of the abbreviated special number to the pointer corresponding to the originating address received from 1 is extracted from the second table TBL2 (step 3) a Next, the extracted address information is As shown in (b), divide it into a side address part and a sub-address part (Step 4)
.

As shown in (C), the destination address section divided in this way is set as the destination address of the call setup information to be sent out, and the destination sub address section is set as the destination sub-address of the call setup information to be sent out ( Step 5).

Subsequently, after performing other information processing (step 6),
The address of the call setting information to be sent (062341111
Routing control is performed based on > (step 7).

Note that the speed dial information registered in the second table TBL2 may be only a part of all subaddresses. Further, by prohibiting public-private-public line connections other than speed dialing using the method of the present invention, it is possible to provide a security function at the same time.

[Effects of the Invention] As described above in detail, according to the present invention, the number of digits of the destination subaddress set by the originating terminal can be greatly reduced, the operation becomes simple, and the field of the destination subaddress This will reduce the number of cases where there is a shortage of resources, and the service can be improved.
