Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is applicable to transmitting a calling ID from a calling station in a network capable of sending a calling ID (digital network, ISDN network, etc.).
This invention relates to a caller identification calling method that calls a designated number in a PBX under the receiving station by sending a caller.

[0002] In recent years, with the development of switching technology using digital networks and ISDN networks, it has become possible to provide various switching services by having the calling station identify the caller's identification number (caller ID). For example, various services such as caller billing information, airline ticket purchases, and other commercial transactions have become possible.

[0003] Also, PBXs can now receive dial-in services from receiving stations, and PBX extension subscribers have individual telephone numbers just like central office line subscribers.
Just like a regular subscriber, the caller can call an extension directly and make a call without going through the PBX switchboard.
The switchboard is designed so that incoming calls from subscribers whose extension telephone numbers are not known or calls received outside of business hours can be relayed to the internal line.

[Prior Art] Conventionally, when attempting to receive a call from a subscriber within the PBX of a receiving station using a public network, the call is first received at the main phone number that has the main number, and then transferred to the extension number of the PBX. Because I receive a copy of my phone, relay operations using my parent phone are extremely troublesome. On the other hand, in the case of the dial-in method, calls can be received directly to the other party's extension phone of the PBX, but the PBX
If the other party's phone number changes due to movement within X, the caller will not know.

[0005] Therefore, a network (digital network,
ISDN network, etc.), the originating subscriber uses the PB under the terminating station.
When attempting to make a call to X, the call must first be made to the representative parent of the PBX, and then an extension number must be specified.

[0006]

In other words, in the conventional calling method, a subscriber other than a dial-in subscriber first calls the representative parent within the PBX. After that, I had to specify extension phone B and have it called. The purpose of the present invention is to enable a fixed number in a PBX to be called directly in a dial-in manner using the caller ID from the caller at the receiving station, so that the user can call the number he or she wants to call. .

[0007]

[Means for Solving the Problems] A diagram of the principle configuration of the present invention is shown in FIG. In the figure, 1 is a caller identification signal (caller ID)
2 is a signal relay station that relays the calling ID and representative number from the originating station to the terminating station; 3 is the terminating station that relays the dial-in number to the PBX; 4 is connected to the terminating station by the representative number. 5 is a network service station that sends a dial-in number to the destination station; 6 is a means for sending a representative number and calling ID to the network service station at the destination station to inquire about the dial-in number; 7 is a network service station , a telephone number management database for managing dial-in numbers for caller IDs corresponding to representative numbers; 8 means for replacing and returning dial-in numbers at the network service station upon request from the receiving station; 9 a representative main telephone within the PBX; 10 11 indicates a PBX extension telephone B, and 11 indicates a calling telephone A having a caller identification signal (caller ID).

[0008] Representative number and caller ID from the calling telephone 11A
The dial-in number converted by the network service station 5 is received by the receiving station 3, and the receiving telephone 10B of the PBX 4 is called.

[0009] The receiving station 3 is configured to have a dial-in number conversion function including the telephone number management database 7 provided in the network service station 5. The PBX 4 and the data management section of the receiving station 3 are configured to have a function of changing the contents of the telephone number management database 7 of the network service station 5 from the PBX 4.

[0010] The data management section of the receiving station 3 is provided with means for identifying whether the number is a representative number or a dial-in number, and in the case of a representative number, it is configured to have a function of converting the caller's dial to a dial-in number.

[0011]

[Operation] A processing flowchart at the receiving station 3 of the present invention is shown in FIG. The figure shows subscriber A who has a calling ID at calling station 1.
When making a call to extension telephone B of PBX 4 connected to receiving station 3, calling subscriber A calls PBX 4's representative parent 9 using the main number, and then has subscriber B call the call, but subscriber A I only call subscriber B on PBX4 for work purposes. ■ The calling ID and representative number from the originating station 1 arrive at the receiving station 3 via the signal relay station 2. ■ Terminating station 3
from the network service station 5 by the dial-in inquiry means 6.
Inquire about the dial-in number from the representative number and caller ID. ■ The network service station 5 searches for the dial-in number from the telephone number management database 7 and selects a PBX that supports the calling ID.
Convert to dial-in number. ■ Network service station 5
Then, the dial-in replacement/return means 8 sends the converted dial-in number back to the receiving station 3. ■ Terminating station 3
Then, using the existing dial-in function, the incoming telephone set 10 is called using the converted dial-in number. ■ Caller A can directly call callee B and have a conversation.

Telephone number management database 7 of network service station 5
The dial-in number of extension telephone B is registered in advance from the main number of PBX4 in correspondence with the calling ID, and the PBX4
Incoming calls to X4 from the representative number having the corresponding caller ID can be made to always call extension telephone B. Therefore, when the receiving station 3 side recognizes that the call is from the caller A to the representative parent 9 of the PBX 4, it can always determine that the connection is to the called party B and make the call.

[0013] In addition, caller A can use the existing PBX dial-in service function as is, and also
This service can also be realized by having the telephone number management database 7 held in the receiving station 3. Note that the content change management function of the telephone number management database 7 can be provided to the data management section of the PBX 4 and the receiving station 3.

[0014] Furthermore, by providing the data management part of the receiving station 3 with a function to identify whether the called number is a representative number or a dial-in number, if the number is a representative number, the caller's dial is changed to the corresponding dial-in number. I can do it.

is sent to the network service station 5. The network service station 5 searches the dial-in number search table 13 registered in advance in the telephone number management database, and detects the dial-in number (35XX) for the receiving telephone B from the representative number and the calling ID. The network service station 5 returns the dial-in number (35XX) to the receiving station 3 based on the dial-in number table 14. At the receiving station 3, the dial-in number (35
XX) and connect as if calling subscriber B directly from calling station 1 using the dial-in number (0AB-CDE-35XX), and subscriber A and subscriber B go through signal relay station 2. You can make direct calls without having to

[0017] Therefore, on the receiving station 3 side, when it is determined from the caller ID that the call is to the representative parent, subscriber B can be called by dial-in without connecting to the representative parent 9. Further, subscriber A can also use subscriber B's dial-in number (0AB-CDE-35XX) as is using the existing PBX dial-in function. The telephone number management database 7 provided in the network service station 5 can also be provided in the receiving station 3 to connect to the corresponding extension subscriber using a pre-registered dial-in number. Further, number change management in the telephone number management database 7 can be performed by making an inquiry to the network service station 5 from the PBX 4, but it is also possible to provide this function to the data management section of the PBX 4 and the receiving station 3. Furthermore, the data management part of the receiving station 3 should have a function to identify whether the called number is a representative number or a dial-in number, and if it is a representative number, it should have a function to change the caller's dial to the corresponding dial-in number. is also possible.

[0018]

[Effects of the Invention] (1) The caller can call the extension number he/she wants to call by simply dialing the main number. (2) Existing PBX dial-in services can also be used effectively. (3) Even if the extension number within the PBX is moved,
Since the caller only needs to dial the main number, there is no need to be conscious of changing the extension number.
