Abstract

PURPOSE:To receive a charge without fail only by transmitting a counting value signal to show the number of times of an accounting signal at the time of the completion of a calling after a periodical signal to show the period of the accounting signal is transmitted in accordance with the starting of the calling. CONSTITUTION:A KCT 41 detects an accounting signal (a), when the second of this comes, a period T is detected by the counting of a clock pulse, the information to show this is given to a KCS 45, a control is executed, and therefore, the KCS 45 sends a periodical signal bI to show the period T by the signal outside a band and this is transmitted through a KSD 47, EX 41 and ZN 3 to a TS1. Consequently, the transmission of the accounting signal comes to be only two times of a periodical signal bI after the calling is started and a counting value signal bII after the calling is completed, the chance that due to the unstability of an electric wave transmitting/ receiving condition, respective these signals bI and II are not received in the TS1 without fail is widely decreased, and a calling time supervising is individually executed based upon the period T in a KCT 17 of the TS1, and therefore, the metering calling charge by the accounting signal (a) to come from a telephone line 6 and the charge receiving amount of TELA are made coincident without fail.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a charging method for charging public telephones installed in mobile stations such as trains, etc., by collecting coins, collecting call charges using a rate card, etc. It is something.

[Conventional technology]

FIG. 3 is a block diagram showing a conventional example, and FIG. 4 is a timing chart showing signals of each part in FIG. 3. In FIG.
S) 1 is equipped with a charging public telephone (hereinafter referred to as station A) 11, and station A11 is equipped with a trunk for switching connection (hereinafter referred to as TRK) 1.
The TRK 12 is connected to a transmitter/receiver (hereinafter referred to as TRX) 13 via an antenna 14, and calls are made by transmitting and receiving radio waves through an antenna 14. 15, which detects the AC billing signal received via the TRX 13 and sends the corresponding DC billing signal to the location A.

In addition, each antenna 2 corresponds to the movement route of TSL.
, = 2n, base stations (hereinafter referred to as ZN) 31 to 3n are installed, each of which is connected to a control station (hereinafter referred to as MS) 4 via a transmission line, and is controlled by MS4. It becomes.

The MS4 selects the one with the best radio wave transmission/reception status with the TSL from among the ZNs 31 to 3n, and connects it to an exchange (hereinafter referred to as EX) 41 that performs tracking exchange, and a telephone line 6 from the central office EX5. TRK provided for exchange connection of
42, and the KR843 attached to it, KR
843 detects a DC billing signal from the telephone line 6 and sends an AC billing signal to the EX 41 in response.

At this point, A11 goes off-hook, inserts a coin, and makes a call, and this information is transmitted to TRK1.
ZN3.2 is sent to TRX13 and a connection request signal is transmitted in response to this signal. ~
3n, and T via EX41.
It is given to the RK 42, and connected to the SIMI communication line 6 by the response of the TRK 42.

Then, when Station A makes a dialing call, this information is similarly given to TRK42 by an out-of-band signal;
Since the dial signal is sent from 2, EX5 responds and establishes an exchange connection with the Itadai telephone set (hereinafter referred to as station B) 7. According to the response from station H, the communication path is completed. A call is made from station A telephone line 6 to station B via TSI and ZN3.

Then, in response to the start of the call, a DC billing signal (-) such as a polarity inversion pulse is sent from the EX5 to the telephone line 6, and during the call, a similar billing signal (凰) is sent with a period T determined depending on the distance of the call. is sent repeatedly, and in response to this, KR843
sends an AC billing signal (b) using an out-of-band signal, which is received by TRXl3 of TS1 via ZN3, and in response to this, KR915 sets a DC billing signal (c) such as a polarity reversal pulse. Accordingly, station A repeats billing by storing coins.

[Problem that the invention seeks to solve]

However, in the past, the transmission of the charging signal was repeated during the call, and in mobile communications using wireless lines, if the charging signal was transmitted when the radio wave transmission/reception situation became unstable, If coins are not collected, there will be a discrepancy between the actual collected amount and the registered call charges on the EXS side, and if the coins are collected using a charge card, it will be difficult to collect the charges every cycle. This has caused problems such as the inadequacy of conventional methods.

[Failure to solve the problem]

In order to solve the above-mentioned problems, the present invention is constructed by the following means.

In other words, in the above-mentioned mobile communication system, there is a means for detecting the cycle of a billing signal that arrives from the telephone line after a call between the public telephone and the telephone line is started, and a means for detecting the cycle of a billing signal that arrives from the telephone line, and a means for detecting a periodic signal indicating the cycle of the billing signal from a base station. means for counting the number of billing signals received from the telephone line during the call, and transmitting a count value signal indicating the counted value via the base station upon completion of the call. A control station is provided with a means for transmitting to a mobile station, a means for receiving and storing the periodic signal, and upon reception of the count value signal, a charge amount is determined based on the contents of the count value signal and the above-mentioned stored contents. means and
The mobile station is provided with means for sending a billing signal corresponding to the billing amount to the public telephone set.

[Effect]

Therefore, after a periodic signal indicating the cycle of the charging signal is transmitted in response to the start of a call, a count signal indicating the number of charging signals is transmitted at the end of the call.
This reduces the chance that the timing at which each of these signals is transmitted coincides with the timing at which the radio wave transmission/reception situation becomes unstable, ensuring that charges are collected, and that charges are collected at each billing signal cycle. First, it is also suitable for installation A, where charges are collected all at once upon completion of a call.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to figures showing examples.

Fig. 1 is a block diagram similar to Fig. 3, and Fig. 2 is a timing chart showing signals of each part in Fig. 1.
In FIG. 1, a billing signal receiver (hereinafter referred to as KSR) that receives AC billing signals is shown for TRK12 of TSI.
16. Charging control device that performs control according to the output of this device (
(hereinafter referred to as KCT) 17, and a charging signal generator (hereinafter referred to as KS
S) 18 is provided, and for the TRK 42 of the MS 4, there is a KCT 44 that detects the DC billing signal and performs control.

A periodic signal transmitter (hereinafter referred to as KC8) that transmits a periodic signal using
45, a count value signal transmitter (hereinafter referred to as KTS) 46 that transmits count value signals under similar control is provided, and M
The configuration is the same as that shown in FIG. 3, except that a sending circuit (hereinafter referred to as KSD) 47 is inserted between EX41 and TRK42 of S4 to send each output of KKC845 and KTS46 to EX41.

Therefore, the exchange connection situation with station B in response to a call from station A is the same as shown in FIG. The timing of arrival is the same as that shown in FIG. 4, but as shown in FIG. In order to detect this and provide information indicating this to the KC845 for control, the KC845 sends a periodic signal (b) I indicating the period T as an out-of-band signal, which is then transmitted to the KSD4.
7, EX41, transmitted to TSL via ZN3.

Then, through TRX13 and TRK12, K
Received by SR16, KCT 17 decodes the output and stores it in internal memory as the value of period T, sets this value to a timer for monitoring call time, and starts repeating timer counting. let

Also, during a call, the KCT44 detects the charge signal (-) and counts the number of times it arrives using a counter, etc., and when the call ends, information on the final count value N is sent to the KTS.
46 for control, the KTS 46 sends a count signal (b) I indicating the count value N as an out-of-band signal, which is transmitted to the TSI via the above-mentioned path.

This count value signal (b2) is also received by the KSR16 of the TSL, and the output of this is decoded by the KCT17 to find the value of N, and also calculates the number of cycles of the actual call time by calculating N-1. The number of times measured is sequentially counted and compared with the number of cycles indicated by the contents of the stored memory. If they are the same, N-1 is used, and if they are different, a larger value is used to determine the actual call time and billing. In order to calculate the amount and give information indicating the amount to be charged to the KSS 18, the corresponding DC billing signal (c) is sent from the KSS 18 to the station A via the TRK 12, and the fee collection according to this is sent to the station A. It will be held in

For each signal (b) I, H, a method such as a combination of specific frequencies outside the communication frequency band or code transmission using various modulations of similar specific frequencies may be used, and for the billing signal (c), The number of polarity reversal pulses corresponds to the amount charged,
Alternatively, an intermittent signal using a pulse code or the like may be used depending on the conditions of position A.

Therefore, the charging signal is transmitted by the periodic signal (b) after the start of the call. , and the count value signal after the end of the call (b)
II), due to the instability of the wave speed reception situation, each of these signals (b)! , II is not reliably received at TSI, and the TSI's K
Since CT17 independently monitors the call time based on the period T, it is ensured that the registered call charge based on the charge signal (,) arriving from telephone port #6 matches the charge collected at station A, and the call is terminated. Place A, which sometimes collects fees in bulk
It is also suitable for K.

However, the charging signal (-) coming from telephone line 6 is 50
If it is an AC signal such as Hz, 16KH, etc., the configuration of KCT41 can be selected accordingly.
The same effect can be obtained by using a separate control channel, etc. to transmit the month and H, and transmitting the period T and count value N using a signal format suitable for this channel.For KCT 17.44, a processor, etc. It's okay.

Furthermore, the period T can be detected in various ways, such as by decoding the dialed number of station A, determining the distance to the ground from station B, and performing detection based on this.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the call charge is reliably collected in response to the end of the call.
Remarkable effects can be obtained in various mobile communication systems equipped with Ajikintake's public telephones as mobile stations.
