A method and apparatus for remotely loading a telephone number into a mobile unit is disclosed. A registration computer in a credit card payment radiotelephone system places a call to a mobile radiotelephone unit and conveys a telephone number to the mobile unit which is stored at the mobile unit. This telephone number may later be recalled and transmitted by the mobile unit to accomplish a telephone call.

A unique cellular telephone (100) connects to a standard telephone set (101) for providing cellular telephone services to subscribers in remote locations not served by a landline telephone system. Cellular telephone (100) includes a cellular telephone transceiver (109), microcomputer (108) and circuitry (102-106) for interfacing the cellular telephone transceiver (109) to the telephone set (101). The interface circuitry (102-107) provides the audio, voltage and dial signal interface to the telephone set (101). The microcomputer (108) controls the interface circuitry (102-106) and is responsive to the telephone set (101) for answering and placing cellular telephone calls. The microcomputer (108) also is responsive to dialing sequences including numerical digits preceded and followed by the # digit for selecting cellular telephone features.

A mobile radiotelephone call synchronization method and apparatus for a radiotelephone system utilizing a credit card for payment of calls is disclosed. Call access is denied a mobile unit until the user runs his credit card through a card reader to input credit card information. After checking list having a valid and invalid I.D., and checking the expiration date stored at the mobile telephone, the information is communicated by the mobile unit to a registration computer for approval. If approval is granted, the mobile unit is enabled for the user to make one or more radiotelephone calls.

Radiotelephone credit card call approval synchronization

A credit-card radiotelephone for a vehicle with a door includes a radio transceiver and a control unit with a telephone handset, credit card reader, hookswitch and door switch. The telephone handset has a microphone, a speaker, and a dial. The radio transceiver has a transmitter, a receiver, and a first microprocessor for electronically locking and unlocking the radio transceiver. The credit card reader reads a credit card number and produces an output indicating the read credit card number. The control unit also includes a second microprocessor coupled to the credit card reader for receiving the read credit card number and determining if the read credit card number is valid, coupled to the first microprocessor, hookswitch and the dial for electronically unlocking said transceiver and placing telephone calls when the read credit card number is determined to be valid, and coupled to the door switch for electronically locking said transceiver means when the door is opened.

Radiotelephone credit card data communications

Method and apparatus for communicating credit card information read at a mobile radiotelephone unit is disclosed. Data read from a credit card is placed in a variable length error protected format and transmitted from the mobile radiotelephone unit to authorize payment of the radiotelephone call.
