Abstract: Automated adjustment of system organization parameters in a wireless communication system is provided by determining the parameter settings using a characterization of signal propagation of the system's coverage area. This characterization is based on measurements of path loss-related characteristics by the system's base stations and wireless terminals. An exemplary path loss-related characteristic is path loss as determined by measuring received signal strength (RSS) at wireless terminals based on signals transmitted at known powers by a plurality of the system's base stations. It is possible for the wireless terminals to take measurement while operating in the coverage area, whether idle or during communication with the system, and for such terminals to be associated with the system's subscribers. A resulting characterization of signal propagation in the coverage area based on the measured path loss-related characteristic can then be used to determine a variety of parameter settings.

Abstract: A level of system self-organization in a wireless communication system is provided using a combined design, planning and verification process to determine system organization parameters. The process determines the parameters based on a measured path loss-related characteristic, such as path loss or bit error rate, between base stations and a plurality of regions in a coverage area. For each region, the characteristic is measured to each base station irrespective of the proximity between the region and the base stations. The measured characteristics enable the prediction of signal strength received at the regions of signals transmitted by the base stations independent of the region location. Accordingly, the characteristics can be measured without information correlating the absolute geographic locations of the regions.

Abstract: A cellular telephone mobile unit position determining method which utilizes a plurality of range transceivers located at known fixed locations adapted to transmit approximately synchronized digital range signals. The method is especially adapted to determine the position of a cellular mobile unit within cellular service areas for determining billing charges and/or access restrictions. According to the invention, the fixed position range transceivers transmit range signals which are received by a mobile unit. The mobile unit determines either the time difference of arrival or absolute time of arrival of the range signals, which in turn is used to determine the mobile unit's position for cellular billing and/or access restriction purposes. The range transceivers are operable to receive an error signal and correspondingly adjust the output of the next transmitted range signal so as to drive the detected synchronization error to approximately zero.
