ABSTRACT:
A method has been provided for using the broadcast channel of a wireless multiple access network to communicate network timing information, or a time-stamp, to remote units. The method defines a broadcast channel protocol which divides communication frames into units called broadcast channel (BC) superframes. Each broadcast channel superframe is given a unique identification number, called a superframe count, which is transmitted by each base station. Then, both the network base stations and remote units can record events using the known superframe count. A method is also disclosed for the network to assign 14-bit identification numbers to remote units being installed into the network, so that communications can be conducted with installed remote units using the identification numbers instead of the 32-bit hardware serial numbers.
