Abstract

PURPOSE:To connect a public utility type radiotelephone set without using a coin by decoding the information on a credit card, sending part or all of the information to an exchange station to confirm the correctness and charging the credit card. CONSTITUTION:The user of an automobile telephone set MSS 21 hooks on, loads the credit card to a card reader CR 10, to read card information. The user confirms that the card information is decoded correctly by using an audible signal from a handset HS 13 or the like and dials to call an opposite subscriber SUB 26 and depresses a send key, then the outgoing connection is started. The information of the credit card decoded by the reader CR 10 is checked, the required part is transferred to a transmission/reception section TRU 15, the expanded format of an incoming data channel is used to transfer the information to an automobile telephone exchange station MTSO 23 via a radio base station MBS 22. The station MTSO 23 uses a credit information collating device CHK 24 to check the correctness, prepares for charging to complete the outgoing connection to the opposite subscriber SUB 26.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to radio telephones, and in particular to credit card or charge card pay radio telephones.

(Prior art) Conventional technologies in this field include Telecommunications Research Institute Research and Practical Application Report VOL, 334.41984 Nippon Telegraph and Telephone Public Corporation Telecommunications Research Institute "Design of in-vehicle equipment for automobile public telephones" P771-783 Or telecommunications facility V
oL, 36 A8 1984 Nippon Telegraph and Telephone Corporation Facilities Bureau “Diversification of Car Telephone Services JP115-118
There was something written in.

Car phones are currently mainly used in private cars, but when applied to general passengers in passenger cars such as shared passes, sightseeing buses, and taxis, as shown in the above-mentioned document, it requires the hands of the crew. Conventionally, coin-operated public-use car telephones have been used to ensure the collection of call charges without the hassle of telephone calls.

(Problems to be Solved by the Invention) However, the coin insertion type has the following problems.

(a) Users must have an appropriate amount of coins on hand.

(b) As a public car phone, billing processing is required, which complicates the circuitry, impairs call quality, and requires a safe to store coins, making it large, heavy, and expensive.

(c) Depending on the safe's capacity, it may be necessary to restrict calls, and periodic coin collection work is essential.

(Means for solving the problem) It is provided that the system is equipped with a means for reading a credit card or a charge card, a means for decoding the card information, and a means for transmitting part or all of the decoded information to an exchange. This is a credit card type wireless telephone with a special feature.

(Function) A means is provided for reading credit card information with a credit card type wireless telephone of the terminal, decoding the card information, and transmitting part or all of the information to the telephone exchange via the wireless base station, The exchange station checks the credit card number, etc., confirms its validity, and charges the credit card.This is a wireless service for public use that does not use coins and does not require the assistance of the crew of passenger vehicles. Allows telephone connection. Therefore, the above-mentioned problem can be eliminated.

(Embodiment) FIG. 1 is a main functional block diagram of a wireless telephone MSS to which the present invention is applied, including a card reading unit CRIO.

The transmission/reception unit TRU 15 further includes a baseband processing unit BB16, a radio system processing unit RF17, and a control unit C0NT 21B.

FIG. 2 is a relay system diagram of a car telephone network including radio telephones MSS to which the present invention is applied; radio telephones MS821,
Wireless base station MBS 22, mobile telephone exchange MTS02
3, a credit card information verification device CHK 24, a general telephone network LNW 25, and a general subscriber (called subscriber here) SUB 26.

FIG. 3 shows an example of a user's wireless telephone MSS operation flowchart.

FIG. 4 is a part of a data format diagram of the upper control channel RECC in the US EIA standard system, and is an example of credit card information transfer using words D1 to D16 of word F and word G.

Next, the operation will be explained.

The user of the mobile phone MSS 21 goes off-hook, inserts a credit card (or charge guard) into the card reader CRZO, and reads the card information. The user confirms on the handset H that the crab P information has been correctly decoded.
Confirm with the audible signal from 813 or the lamp information of the switch/key/lamp section SKL 12.
When the user dials the outgoing number for calling the other subscriber SUB 26 on the dial key and presses the send key located at 5KL12, an outgoing connection is initiated. The information such as the credit card number decoded by the CRIO is subjected to a predetermined check, and necessary parts specified in advance are transferred to the control unit C0NT 21 B of the transceiver unit TRU 15. During a series of transmission operations, the transceiver unit TRU 15 performs the following operations:
Using the extended format of the multidirectional data channel, credit card numbers or information containing them can be sent to the mobile telephone exchange MTSO2 from the wireless base station MBS 22.
Transfer to 3. The MTSo 23 transfers this to the credit card information verification device CHK 24, where its validity is checked, and then the MTS 023 prepares to charge the credit card number and sends it to the other subscriber SUB 26 via the general telephone network LNW 25. Complete the outgoing connection to.

More details about credit card information transfer.

When the present invention is applied to the US EIA standard system, there is a method of putting credit card information on the uplink control channel RECC. That is, EIA standard IS-3-BSli! -C
'I! For example, if you use word F1 word G in Figure 4 according to the extended telephone number transfer format of ION 4, 1
A 6-digit decimal code can be transferred.

Also, regardless of the control channel RECC, the voice channel RVC
There is a method. In this case as well, EJA standard IS-3-
B 5ECTION 4 (7) Upper voice channel RV
This is done in accordance with the extended phone number transfer format using CK.

Alternatively, as shown by the dotted line in Figure 1, a separate voice band modem MODEM 19 is built into or connectable to the car telephone, and a voice band modem facing the car telephone exchange MTSO23 is also installed, and credit card information is sent via the modem. There is a way to transfer.

The information transfer format and signal medium for information transfer described above are just examples, and although the explanation was given in the case of a car telephone, they can be easily applied to radio telephones for trains, ships, and airplanes. It is easy to apply to mobile phones, and can be applied to temporary telephones and rental telephones.

(Effects of the Invention) As described in detail above, according to the present invention, the following effects can be expected.

(a) According to the present invention, wireless telephones not only in automobiles but also in airplanes, ships, trains, etc. can be freely used by an unspecified number of passengers without the need for crew members, and can be used without charge from users. Collection can be carried out easily and reliably.

(b) Unlike conventional public wireless telephones, it does not require a billing signal transmission/reception function, has a simple circuit, and can prevent call quality from deteriorating.

(c) Users do not need cash such as coins.

(d) It does not require a strong and strong safe or periodic collection work like a coin-in type, and can be made smaller and lighter.
It can also be applied to mobile rental phones or temporary phones.
