Description

DETAILED DESCRIPTION OF THE INVENTION [Invention 1] (Industrial Application Field) The present invention relates to a called side billing information notification system in a telephone.

(Prior art) Conventionally, billing information for a central office line call is calculated by adding up the calling number information by time information etc. at the central office exchange on the caller's side. section, but the respondent is not informed.
Even if the responder wanted to know the cost of the call, it was impossible.

(Problems to be Solved by the Invention) As described above, with the billing information display function currently provided, call charge information cannot be known from the responder side.

For this reason, even if it is necessary for the answering party to bear the call charges, since call charge information cannot be obtained, the caller has no choice but to have the caller pay the call charges that should normally be borne by the called party, or They had to resort to having the call charges billed to them later.

In the former case, there is a possibility that the relationship between the two parties will be disturbed, and in the latter case, the process is very troublesome.

The present invention has been developed in consideration of these problems, and its purpose is to enable the called party to check call charge information at any time during the call or immediately after the call, and to allow the called party to check the call rate information at any time during the call or immediately after the call. To enable a called party to easily process call charges to be paid without causing any trouble.

[Configuration of the Invention (Means for Solving the Problems) In order to solve the above problems, the present invention utilizes a caller ID number notification function such as the 15DN service. That is,
In conventional central office lines, it was not possible for the called party's private branch exchange to recognize the caller's dialed number. However, l5D
If the caller makes a call through a central office line, unless the caller masks the ID number by realizing the N service, etc., the called party's exchange and terminal will be able to recognize the caller's ID number.

The called-side billing information notification system of the present invention that utilizes the above function is configured to notify the private electronic branch exchange of the response time of each extension terminal, its caller's dialed number, and the call rate prepared for billing at the time of the call. When there is an incoming call from the public network to the extension terminal of the horizontal electronic exchange, the data is written to the memory area in response to a request from the responder terminal when the incoming call is answered. Using the caller's dialed number, the call time calculated from the response time, and the call charge frequency, the receiver's terminal makes a call to the caller's terminal. The system is characterized in that charging 141 is calculated and the charging information is notified to the responder terminal.

(Function) The present invention makes it possible for the called party to check billing information, which conventionally could only be obtained by two parties during a call.Therefore, when the answering party wants to bear the call charges, Well,
You can easily obtain call charge information by pressing the service request special number or service request function key just before answering or during a call. This eliminates the need for research on the part of the person concerned.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

This embodiment shows an example in which call charges are displayed using the LCD section of an extension terminal.

FIG. 1 is a diagram showing a connection between a private electronic branch exchange l5DN terminal connected to a private l5DN public network. ] is a central office line connected to the public network 20, 2 is a private branch exchange, and 3 is an 15DN extension terminal.

FIG. 2 is a schematic configuration diagram of the private electronic branch exchange 2 and the 15DN extension terminal 3 for implementing this service, where 4 is a central control section, 5 is a terminal control section, and 6 is a memory section. The central control unit 4 calculates charges based on information stored in the memory unit 6, and the terminal control unit 5 is in charge of communication between the central control unit 4 and each extension terminal 3 and control of each extension terminal 3.

The memory unit 6 includes a current time timer 7, a terminal response time storage unit 8V, a caller ID number storage unit 9, and a call charge frequency table]O. The current time timer 7 stores the current time, the terminal response time storage section 8 stores the time when each extension terminal 3 responded to an incoming call, and the caller ID number storage section 9 stores the current time when each extension terminal 3 responds to the incoming call. This table stores the ID number of the caller for each terminal when the caller responds to a call from the terminal. And call charge frequency table 1
0 stores information on call charges per unit time when making a call from the extension terminal 3 in the private electronic branch exchange 2.

The extension terminal 3 also includes an LCD section] 1 for displaying caller ID number 3 when receiving a call, call charge information, etc. when implementing this service, and a service request function key 12 for requesting this service. It is connected to the terminal control section 5 of the main body of the private electronic branch exchange 2.

In such an exchange system, when there is an incoming call to the l5DN extension terminal 3 connected to the local electronic branch exchange 2 from the central office line 1, and this service is requested from the l5DN extension terminal 3, the local electronic branch exchange 2 receives the call as shown in Fig. 3. It operates according to flowchart 1 shown in .

First, when there is an incoming call at the l5DN extension terminal '3 (step a), the ID number of the caller is displayed on the LCD section 11 of each l5DN extension terminal 3 via the private electronic branch exchange 2 (
Step b).

At this time, if the responder wants to know the call charge information for the call, he/she responds after inputting the service request key 12 from the extension terminal 3 (steps c, d). Then, the l5D
A service request signal is sent from the N extension terminal 3 to the private electronic branch exchange 2, and the central control unit 4 in the private electronic branch exchange 2, which receives this via the terminal control unit 5, stores the caller ID number in the memory unit 6. The ID number of the caller who received the call at the service requesting terminal is stored in the storage section 9 (step e), and the terminal response time is stored in the terminal response time storage section 8 at the same time as the response (step f).

Then, when the call ends and a disconnection signal is transmitted to the central control unit 4 (step g), the central control unit 4 sets the current time timer 7.
and the call time obtained from the response time stored in the terminal response time storage unit 8 (step h), the ID number stored in the caller ID number storage unit 9, and the call rate stored in the call rate frequency table 10. Basic call charge (billing information per unit time) obtained from the current call charge frequency (Step i)
(step j), and reports the results to the requesting terminal 3 in terms of basic call charge, call time, call charge, etc. (step k), and the extension terminal 3 displays the received information on the LCD.
section] 1 for a certain period of time (step 1), and the service ends.

With the above configuration and operation, the service request function key 12
By pressing , you can easily obtain call charge information, so you can ask the caller to bill you for the call later.
This eliminates the need for the recipient to investigate.

In addition, in the above embodiment, the case where the present invention is applied to the 15DN communication network has been described, but it can also be realized with other communication networks.

Further, although the case where billing information is displayed and notified on the LCD section 11 of the extension terminal 3 has been shown, it is also possible to notify by voice.

[Effects of the Invention] As explained above, according to the present invention, billing information, which conventionally could only be obtained from the caller side, can be easily obtained upon request from the called terminal side, so that the call charges can be reduced to the calling side. Even if you want to pay the charge, you can check the call charge without placing any burden on the caller, so you can easily process the call charge payment without jeopardizing your relationship.

Additionally, by knowing the call charges on the receiving side, there is a synergistic effect in that the receiving side can be more considerate about unnecessary long phone calls.
