Abstract

PURPOSE:To calculate and manage the charge for a collect call by providing a collect call accepting telephone set with a button with which information, which can determine the time for which a unit charge allows speaking, like the toll number of an originating subscriber which a respondent hears from the originating subscriber is inputted. CONSTITUTION:The respondent who hooks off a collect call accepting telephone set 3 hears the toll number from the originating subscriber. When the toll number is inputted from a function button 6 provided on the telephone set 3, a central processing unit 4 receives the toll number to calculate the time for which the unit charge allows speaking. The unit 4 discriminates the speaking start time and the end time of the call and sends information to a charge management device 5 together with the extension number of the telephone set 3. The device 5 stores this information, and this stored information is printed out by operator's operation. Consequently, a management table of the charge for telephone is obtained which indicates the telephone set used by each respondent, the speech time, the originating subscriber from which the respondent responded to the call, and the charge for telephone.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a call charge management method in a private telephone exchange equipped with a central office line trunk for incoming paid calls and a telephone set for accepting one incoming paid call, and more specifically, a method for managing incoming call charges. This also relates to a call charge management method that can manage call charges for incoming calls.

(Prior Art) A call charge management device installed in a conventional private branch telephone exchange device manages the call charge for an outgoing call from an extension telephone to a affiliated central office.

(Problems to be Solved by the Invention) Conventional call charge management devices calculate the charge for one call based on the telephone number information of the called party and the duration of the call when a call is made from an extension telephone to the affiliated telephone station. For one incoming call, it was not possible to calculate the cost of the call.

SUMMARY OF THE INVENTION An object of the present invention is to provide a call charge management system that is capable of calculating and managing a call charge even for a single incoming pay call in a private branch telephone exchange that accommodates a central office line trunk for incoming pay calls.

(Means for Solving the Problems) In order to achieve the above object, the call charge management system for incoming paid calls according to the present invention includes a central office line trunk that receives incoming paid calls from the affiliated telephone office, and a condolence phone that accepts incoming paid calls. In a call charge management method for a private telephone exchange that accommodates
The telephone for accepting incoming paid calls is provided with a button for the answerer to input information that can determine the callable time based on the unit charge, such as the caller's area code that the answerer has heard from the caller, and based on the above information. A control means for determining a callable time for a unit charge, identifying the call start time and end time of the call, and outputting call charge information such as the time, the call start time, the call end time, and the called extension number. and a charge management device that stores the call charge information output from the control means and prints out the call charge information as necessary.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a relay system diagram showing an embodiment of the call charge management system according to the present invention.

When an incoming paid call arrives at a private branch telephone exchange (hereinafter referred to as -PBXJ) via the central office trunk 1, the central controller 4 controls the switch section of the PBX to
and line circuit 2. As a result, the incoming call is connected via the line circuit 2 to the incoming call receiving telephone 3 housed in the switching device.

The responder who has off-hook the telephone 3 for accepting incoming paid calls asks the calling party for its area code (information that can determine the length of time a call can be made for a unit charge).

When this area code is input through the function button 6 installed on the telephone 3 for accepting incoming paid calls, the central processing unit 4, which functions as a control means, receives this area code and charges the unit charge. Calculate the available talk time. Furthermore, the call start time and end time of the call are identified, and the above information is sent to the charge management device 5 together with the extension number information of the telephone 3 for accepting incoming paid calls.

The charge management device 5 stores information sent from the central processing unit 4. The stored information can be printed out by the operator's operation.

Therefore, it is possible to obtain a call charge management table showing which answerer of which incoming call receiving telephone set answered the incoming pay call from which caller, from what time to what time, and how much the call charge was.

(Effects of the Invention) As explained above, the present invention allows the answerer of the incoming paid call accepting condolence telephone to make a call for a unit charge such as the area code of the telephone number of the caller heard from the caller. By inputting information that can determine the duration of the call from the incoming paid call reception telephone, the call charge for the incoming paid call can be managed by the call charge management device.

Therefore, if you print out and obtain a call charge management table later, it is effective in reducing wasted call time in incoming paid calls.
