Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a call billing system, and particularly to a call rate calculation method.

Call billing methods include the so-called frequency meter method, which creates reference period pulses with different periods depending on the distance of the call, and calculates the number of calls by counting the reference period pulses sent out during a call. There are two methods: a so-called calculation method in which the call duration is calculated from the time difference with the call end time, and the number of calls is calculated by dividing this by a reference time corresponding to the call distance.

The present invention is implemented in a call billing method that employs an arithmetic method. Conventionally, in such a calculation-based payment method, not only the cumulative value of the number of calls for each subscriber, but also the details of each call (destination number, call start time, number of calls, etc.) have been reported. In particular, in order to obtain data related to the real time, such as the start time of a call, the money-grabbing device has a clock means (hereinafter referred to as a time clock) that displays a time that matches the real time. There is.

When calculating the call time, it is common to use the displayed value of the time clock and to subtract the call start time from the call end time. However, this method of calculating the call time from the actual time has the following problems.

In other words, when the time clock, which is the basis of calculation, no longer displays the real time, and if it is corrected to match the real time, the call time will be changed during the call at that point. The real time display, which is the basis of The correct call time cannot be calculated unless the time is corrected according to the corrected time length. In addition, the time clock display is binary (normally, the period of the basic clock pulse is 0.9 sand, and when obtaining the time in seconds from the clock pulse)
, sexagesimal (seconds to minutes and minutes to hours), and binary numbers (hours to days), and calculation of call time using such numbers becomes very complicated.

The present invention has been made to eliminate such drawbacks of the conventional technology.For this reason, in addition to the time clock whose display matches the real time, the present invention also provides a clock that displays non-real time, that is, a time clock that displays time relative to the actual time. A second clock (hereinafter referred to as a counter clock) is installed to display the call time, which is expressed as the relative time difference between the start of the call and the end of the call, and is used to record the call details for each call. The above-mentioned time clock is used to indicate the actual time such as the call start time.

Embodiments of the present invention will be described below with reference to the drawings.

The drawing is a block diagram showing an embodiment of the present invention, and CC
is the money control unit, TIM is the time clock, CNT is the counter clock, TM is the trunk memory, MA is the frequency accumulation memory, and MB is the call details memory. The time clock TM receives the reference clock pulse and displays the real time, and the counter clock CNT receives the reference clock pulse and ticks at fixed time intervals, for example, every 0.9 minutes, regardless of the above-mentioned real time.

In the trunk memory TM, a storage location for data necessary for money fraud processing is set for each trunk related to a call that requires an indication of call time, for example, a central office line trunk. The data required for money fraud processing is the location information of the calling subscriber, the Obijo code of the called party (the called subscriber), the call start time (the time displayed on the time clock TM), and the counter clock at the start of the call. C
This is the value of NT, etc. A storage location for the integrated value of the call frequency for each subscriber is set in the frequency integration memory MA.

The call detail memory MB stores monetary information regarding each call.

Here, the financial information includes the number of the calling subscriber (subscriber), call start time, number of the other party, number of calls, etc. The Kenkin control unit CC creates information to be stored in each memory TM, MA and MB, and stores the information in each memory TM, MA.
It is a part that performs control related to transfer processing, such as storage processing in the MB and storage processing in the MB, and is usually composed of a microprocessor. When a calling subscriber makes a call, for example to make a telephone call, the concession control unit C
C first sets the accommodation location information of the calling subscriber in the trunk memory TM at a position corresponding to the trunk captured for the above-mentioned call, and then, after the dialing of the calling subscriber is completed, the called party is determined from the dialing information. When the other party answers the call, the real time display on the time clock TIM and the counted value on the counter hour hand CNT are read out and stored in the corresponding trunk memory TM.
Set the call start time storage location and the call start counter clock count value storage location.

Thereafter, when the call ends, the money-grabbing control unit CC detects the end of the call, reads out the counted value of the counter clock TIM at that time, and uses that value to calculate the counter clock TIM at the time of the start of the call previously stored in the trunk memory TM. Subtract the numbers to find the call time. (However, if the count value at the end of the call is smaller than the count value at the start of the call, the count value at the start of the call is subtracted from the value obtained by adding the final count value of the counter clock TIM to the count value at the end of the call.) On the other hand, the trunk The band code of the other party to the call stored in the memory TM is obtained, the charge unit time is obtained from it, the call frequency is calculated by dividing the above call time by this value, and this call frequency is stored in the frequency accumulation memory MA. is set to be added to the frequency integrated value corresponding to the calling subscriber. Also, at this time, the concession control unit CC
Information such as the number of the calling subscriber, the call start time, and the number of the other party to be called is obtained from the TM and stored in the call detail memory MB along with the call frequency calculated above. The call frequency for each subscriber is read out from the frequency accumulating memory MA, and the call details for each call are read out from the call detail memory MB as necessary, and are printed out by, for example, a printer. In addition, the display values of the time clock TIM and the counter clock CNT are updated every moment with a reference clock pulse (for example, 0.9 sand), but the display value of the time clock TIM is independent of the display value of the counter clock CNT. The value can be changed. That is, the time clock TI
When the actual time display by M progresses or lags behind, input a real time correction command to control the transfer control unit CC.
corrects the displayed value of the time clock TIM. As described above, according to the present invention, a second clock that displays relative time is provided separately from the clock for displaying the real time, and the call time and minutes are calculated by this second clock, so that the actual time is calculated. Even if the time has been corrected, it is possible to carry out fraud processing independently of the above-mentioned actual time correction when calculating the call time, and calculations for calculating the call time can be performed using, for example, a binary number (the reference clock pulse period is Since the processing can be performed in only 0.5 seconds), the calculation process becomes extremely simple.
