摘要： A method, apparatus and system is described for distributing accurate time-of-day information from an existing telecommunications infrastructure without modifying the existing infrastructure. In particular, the system comprises a base station device which continually receives extremely accurate time-of-day information from, by way of example and not by limitation, a GPS (Global Positioning Satellite) system, a local atomic clock, or a wired or wireless time standard. The base station periodically places time-of-day information into standard paging packets for transmission over a standard paging network. The paging packets are sent over telephone lines to the paging terminal for transmission whenever a time slot for transmission becomes available. The base station device records the actual time of transmission of the paging packet containing the time-of-day information and prepares the next time-of-day packet by placing the exact transmission time of the previous time-of-day packet sent. In the receiver, an algorithm is used to extrapolate the current time-of-day based on the history of transmitted packets containing measured time-of-day information of past transmissions.
