Abstract

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.

Claims

1. A method of mobile radiotelephone call processing in a radiotelephone call processing in a radiotelephone system which utilizes a registration computer to approve call changes to a mobile radiotelephone unit user'"'"'s credit card, the credit card having stored identification and information such as expiration data resident in the credit card, comprising the steps of:

reading the credit card stored identification and information when the credit card is slid through a card reader at the mobile radiotelephone unit;

comparing said read credit card stored identification to information which is stored at the mobile radiotelephone unit and which identifies at least a last valid credit card identification and a last invalid credit card identification;

placing said mobile radiotelephone unit in a locked condition if said comparison indicates a match between said read credit stored identification and said last invalid credit card identification;

placing said mobile radiotelephone unit in a unlocked condition if said comparison indicates a match between said read credit card stored identification and said last valid credit card identification;

checking the card expiration data from the credit card stored information if a match is not found for either valid or invalid credit card identification and transmitting at least a portion of the read credit card stored identification and information to a registration computer;

receiving one of a plurality of data messages, said plurality of data messages including a data message containing service approval information and a data message containing service denial information

placing said read credit card stored identification in said last invalid credit card identification memory in the mobile radiotelephone unit if said service denial information data message is received;

placing said read credit card stored identification in said last valid credit card identification memory in the mobile radiotelephone unit if said service approval information data message is received and enabling system access to allow a telephone call;

terminating said telephone call upon the radiotelephone user'"'"'s indication of the end of the telephone call; and

locking said mobile telephone unit in response to a lock trigger.

2. A mobile radiotelephone unit which is adapted to place radiotelephone calls in a radiotelephone system which utilizes a registration computer to approve call charges to a mobile radiotelephone user'"'"'s credit card, the credit card having stored identification and information such as expiration date resident in the credit card, the mobile radiotelephone unit comprising:

means for reading the credit card stored identification and information when the credit card is slid through a card reader at the mobile radiotelephone unit;

means for comparing said read credit card stored identification to information stored at the mobile radiotelephone unit and which identifies at least a last valid credit card identification and a last invalid credit card identification;

means for placing said mobile radiotelephone unit in a locked condition if said comparison indicates a match between said read credit card stored identification and said last invalid credit card identification;

means for placing said mobile radiotelephone unit in an unlocked condition if said comparison indicates a match between said read credit card stored identification and said last valid credit card identification;

means for checking the card expiration date from the credit card stored information if a match is not found for either valid or invalid credit card identification and for transmitting at least a portion of the read credit card stored identification and information to a registration computer;

means for receiving one of a plurality of data messages, said plurality of data messages including a data message containing service approval information and a data message containing service denial information;

means for placing said read credit card stored identification in said last invalid credit card identification memory in the mobile radiotelephone unit if said service denial information data message is received;

means for placing said read credit card stored identification in said last valid credit card identification memory in the mobile radiotelephone unit if said service approval information data message is received and means for enabling system access to allow a telephone call;

means for terminating said telephone call upon the radiotelephone user'"'"'s indication of the end of the telephone call; and

means for locking said mobile telephone unit in response to a lock trigger.

3. A mobile radiotelephone unit in accordance with claim 2 wherein said lock trigger further comprises a timer.

4. A mobile radiotelephone unit in accordance with claim 2 wherein said lock trigger further comprises a switch.

5. A mobile radiotelephone unit in accordance with claim 2 wherein said lock trigger further comprises means for detecting the opening of a vehicle door.
