Abstract

A method for secure and prompt distribution of critical operational information to a wireless cellular or PCS subscriber station via wireless interface which includes the steps of generating operational information, storing the operational information into a first memory of a wireless base station, and transmitting at least a portion of the operational information stored in the first memory to a wireless subscriber station via a wireless interface at random times during an active conversation state of the wireless subscriber station. The operational information stored in a second memory register in the subscriber station is updated with the operational information transmitted from the first memory. Where at least a portion of new operational information is received by the subscriber station, a first update counter is incremented to reflect the number of operational information updates received by the subscriber station. The value of the contents of the first update counter is then reported to the wireless base station via a wireless interface. Where the value of the contents of the first update counter is different from the value of the contents of a second update counter in the base station, the base station will synchronize the second counter to be the same as the first counter, and will re-transmit a portion of the operational information.
