METHODS FOR CELLULAR PAY PHONE/DEBIT PHONE SUPPORT |
摘要 |
A communications system for providing charge rate support, and a method for providing Authentication and Privacy, to pay/debit phones are disclosed. A cellular controller within the system enables the pay/debit phones to communicate with other phones. The system calculates a charge rate for a call being made by a pay/debit phone and send s it to that phone in a message containing a standard air interface message that is being used in a non-standard manner. This message allows the pay/debit phone to determine the charge rate. The charge rate information is also sent using mobile station control messages i n a non-standard manner. Each control message contains an Order Code, a Qualifier Code, and a Local/Message Type. A first combination of these items is assigned to Authentication and Privacy and a second combination, mutually exclusive with the first, is assigned to sending charge rates.
