Abstract

PURPOSE:To make the charge lower the longer a telephone call becomes, by varying the charging period of a charging signal at a mobile station as the telephone time becomes longer during the telephone call. CONSTITUTION:The charging period signal is determined by a counter 16, an out-band frequency is determined by a charging device 10 and the charging signal is sent out to the mobile station by a charging signal transmitter 17. The mobile station supplied the charging signal to a charging signal transmitter(KSEND) 15 with the charging period signal firstly. The signal is received by a charging period signal device 3 and stored in a shift register 14 and the counting second period of a counter 13 is determined by the shift register and supplied to the charging signal transmitter 15 while shifted in the shift register. Similarly, the specification of the counter 13 is determined according to the condition of the shift register.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a billing method in a mobile communication system.

(Prior art and its problems) FIG. 3 is a schematic diagram of a conventional mobile communication system. In the figure, ■ is the mobile station (TS) terminal public telephone (location A), 2 is the trunk (TRK) that connects the mobile station to an exchange, 3 is the mobile station's billing signal detection control device CI (RFC), and 4 is the mobile station's charging signal detection control device CI (RFC). Mobile station transmitter/receiver (RX, TX).

5 is the antenna of the mobile station, 6 is the base station (ZN, ~ZN2
) antenna, 7 is the base station transmitter/receiver (X, TX)
.

8 is the control station's tracking exchange device (EX), 9 is the trunk (TRK) that connects the control station to the exchange, 10 is the control station's billing device (KO8C), 1] is the general terrestrial fixed subscriber telephone exchange, 12 is a subscriber telephone set at a terrestrial fixed subscriber telephone office (
(131, (C) represents the billing signal sequence as shown in FIG. 2. This operation is performed when the handset is raised at the public telephone 1 of the mobile station and a coin is inserted.

The transmitting/receiving device 4 is activated by the control of the trunk 2 that performs the exchange connection, and the mobile station antenna 5 sends out a connection signal, which is received by the base station antenna 6 and sent to the base circumference speed receiving device 7.
．． The trunk 9 is activated via the tracking exchange device 8 of the control station (MS). The trunk 9 of the control station activates the central office exchange and connects to the subscriber telephone 12. That is, the line between the mobile station and the subscriber telephone of the control station is connected.

When the subscriber telephone 12 of the telephone office responds, the response signal is detected by the trunk 9, and a charging signal for billing the call fee is received from the telephone office 11 as shown in (5) in FIG. Convert to out-of-band signal for transmission to mobile station10
0 The signal (B) is sent from the charging device. Control station tracking exchange device8. Base station transmitting/receiving device7. When the billing signal is sent to the mobile station via the antenna 6, the mobile station's antenna 5. Transmitting/receiving device 4. C) The billing signal detection control device 3 operates via the trunk 2 and coins are stored in the public telephone 1 by the signal.

During a call, a charging signal is periodically sent from the charging device 10 of the control station, and the mobile station public telephone 1 sends a charging signal each time.

Coins are stored. The signal flow is as shown in FIG.

As shown in FIG. 2, in the current system, if the charging signal interval from the landline telephone station is set to be a T-second periodic interval, charging is done at T-second intervals from the start of the call to the end of the call. That is, in the current system, once the billing seconds interval is determined, it does not change whether the call is for a short time or a long time.

When determining the number of seconds charged, consider short-distance calls, long-distance calls,
There are different rates for daytime and night calls.

However, considering the trends of the times and the development of the service industry,
It would be a very irrational system if there was no difference in charges for short and long calls.

(Objective) In order to solve these drawbacks, the present invention detects a charging cycle signal (charging index or number of seconds) at a control station.

This signal is transmitted to the mobile station, and the mobile station sends the signal once (one charge).
If the number of seconds charged for each call is extended, the longer the call time for long-term callers, the longer the call will be charged per call, which will help improve service.

(Example) An embodiment of the present invention will be described in detail below.

FIG. 1 is a schematic diagram of a mobile communication system according to an embodiment of the present invention. FIG. 4 is an explanatory diagram of the charging signal sequence of FIG. 1. 1-12 and (A) dB in the figure).

(C) has the same meaning as FIGS. 3 and 2. In the figure, 13 is a seconds counter controlled by a charging cycle signal and a shift register, 14 is a shift register, and 15 is a charging signal sending device for supplying charging signals to public telephones.

Reference numeral 16 denotes a counter for identifying the billing cycle at a control station, and 17 is a billing signal sending device. This operation is the same as that shown in FIG. 3, from the calling operation of the mobile station public telephone to the response of the landline fixed subscriber telephone.

A detailed explanation will be given below after the connection between the mobile station public telephone and the landline subscriber telephone is completed. Detecting the charging cycle from the prisoner's charging signal (or determining the charging index directly from the dialed number) Determine the charging cycle signal using 160 counters,
The out-of-band frequency is determined by the charging device 0 and sent to the mobile station by the charging signal transmitting device 17 9.

In the mobile station, a billing signal detection control device 3 receives a billing cycle signal, and first provides a billing signal to a billing sending device (KSEND) 15 based on the billing cycle signal. That is, in a public telephone, first, at the start of a call (displaying the other party's response), after receiving a 1-by-1 billing cycle signal, control is performed to extend the number of seconds from the third 1-to-9 billing signal. In Figure 4, determine the charging cycle signal (B) from the first and second prisoner, and extend the number of seconds in the form of △tl, △t2...△in in (C). . The control system for this part will be further explained with reference to FIG.

The billing cycle signal is received by the device 3 in the figure and is first stored in the shift register 14. The counter 13 determines the number of seconds by the shift register, and supplies it to the billing sending device 15 at the same time as it is shifted to the shift register.

Similarly, depending on the shift register conditions, the counter 13
The designation is decided. When the call ends, it is reset from the trunk 2 by a circuit not shown.

(Effects) As explained above, according to the present invention, if the control station transmits the charging cycle signal to the mobile station and the mobile station controls the number of seconds to be charged, the longer the call time is, the lower the call charge will be, making it a public service. Significant effects such as improved services can be obtained in mobile communication systems.
