Method for determining organization parameters in a wireless communication system
First Claim
1. A method of calculating a system organization parameter for a wireless communication system, the method comprising:
- intermittently measuring path loss-related characteristic between a base station and one or more wireless terminals of the wireless communication system in substantial absence of correlation to an absolute geographic location regarding where the path loss-related characteristic measurement occurs thereby forming a measured path loss-related characteristic measurement, wherein the one or more wireless terminals operate as normal wireless terminals in the wireless communication system;
determining a signal propagation characterization that relates the measured path loss-related characteristic measurement to the base station and the geographic location of the one or more wireless terminals; and
altering the system organization parameter for the wireless communication system based on the signal propagation characterization.

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.
