Patent ID: 8264319

Claim:
A method for transmitting a message in an asynchronous time-division multiplex communication system, the method comprising: receiving stock share price data to be transmitted to subscriber pagers; forming the data into data payloads of data packets; assembling the data payloads with headers containing destination information including an address of a receiving subscriber pager, each payload being addressed to a single pager; scheduling transmission of the payloads one per time slot in a sequence of time slots comprising an original schedule, wherein a first subscription option associated with a particular subscriber pager affects how often payloads are addressed to the particular subscriber pager; receiving a request to transmit a stock crash warning priority message, the request being generated externally of the communication system transmitting in a first time slot after receiving the request, the stock crash warning priority message only to subscriber pagers associated with a second subscription option in response to the request; and rescheduling transmission of the payloads in a sequence of time slots delayed one time slot from the time slots of the original schedule.
