Patent ID: 7493129

Claim:
A method for use in a cellular communications system having a centralized radio processing portion (hotel) in communication with a plurality of remote air interface radio portions (RH) over a transport medium, the method comprising: in the centralized radio processing portion, compensating for a fixed delay associated with the transport medium coupling the centralized radio processing portion and one of the remote air interface radio portions in evaluating a time period corresponding to a variable delay between a transmission by a mobile station and receipt of the transmission by the centralized radio processing portion, the mobile station communicating with the one of air interface radio portions, the transmission being received by the centralized radio processing portion from the one of the remote air interface radio portions; wherein the evaluating is for synchronizing calls by adjusting a transmission timing of the mobile station according to the evaluation of the time period corresponding to the variable delay; and wherein the compensating for the fixed delay includes subtracting out the fixed delay in a calculation of the time period corresponding to the variable delay.
