Abstract
A method for locating concentration of mobile radio (MR) traffic in a coverage area 50 by identifying the locations where MRs (12) in the coverage area 50 are actively making calls. Signal strength measurements at test sites (40) of interest within the coverage area (50) are made and compared with signal strength measurements taken from operating MRs (12). A plot of matches can be kept and used to traffic the locations within the coverage area (50) revealing where concentrations in the coverage area (50) exist.
Claims18
In a wireless communications network including a plurality of base transceiver stations (BTSs) and at lease one testing device configured to make signal strength measurements from the BTSs, a method of profiling locations of mobile radio (MR) traffic within coverage areas served by the BTSs comprising the steps of:
- (A) causing said testing device to make initial calibration signal strength measurements for signals from said BTSs;
- (B) recording said initial calibration signal strength measurements and associated locations where said initial calibration signal strength measurements were made;
- (C) causing said MRs to make signal strength measurements from the BTSs within said coverage area;
- (D) comparing the signal strength measurements made by each of said MRs with the initial calibration signal strength measurements to determine a best match for each MR;
- (E) recording as a location for each MR, the location associated with the initial calibration signal strength measurement of the best match for each MR;
- (F) determining whether radio propagation conditions within the coverage areas have changed since the initial calibration signal strength measurements were made:
- (G) upon determining that radio propagation conditions within the coverage areas have changed, causing the testing device to make updated calibration signal strength measurements for signals from said BTSs;
- and
- (H) repeating steps B through E utilizing the updated calibration signal strength measurements in place of the initial calibration measurements.
A method of profiling mobile traffic concentrations in the coverage area served by one or more base transceiver stations within a wireless communications network, the method comprising;
- obtaining a set of calibration signal strength measurements for all base stations within the coverage area;
- recording an associated position with each of the calibration measurements;
- at each of the base station within the coverage area, measuring the signal strength from mobiles within the coverage area;
- comparing the calibration signal strength measurements with the measured signal strength from mobiles within the coverage area to determine when there is a match within a tolerance;
- recording the associated positions of matches within the coverage area;
- periodically repeating the calibration measurements for selected positions within the coverage area;
- determining from changes in the calibration measurements, when radio propagation conditions have changed within the coverage area;
- and
- obtaining a new set of updated calibration measurements for all base stations within the coverage area whenever it is determined that the radio propagation conditions have changed.
A system for profiling the concentration of MR traffic within a coverage area of a wireless communications network comprising:
- a plurality of base transceiver stations (BTSs) located within said coverage area;
- at least one testing device configured to make calibration measurements of the signal strength of said BTSs at each location where said testing device can be located within said coverage area, and to record an associated location for each calibration measurement;
- a plurality of mobile radios (MRs) within the transmission range of said BTSs;
- means for recording the calibration measurements made by said testing device along with the associated locations;
- means for comparing said calibration measurements with the measured signal strength of said plurality of MRs, and for determining a best match;
- means for determining whether radio propagation conditions within the coverage area have changed since the calibration measurements were made;
- and
- means for causing the testing device to make updated calibration measurements of the signal strength of the BTSs at each location where the testing device can be located within the coverage area.
