Note that the estimated loc sigs are determined using verified location signatures in the Location Signature data base.That is, it is an aspect of the present disclosure to be extensible so that other environmental factors of the coverage area 120 affecting the accuracy of location hypotheses may also be incorporated into the context adjuster 1326.More precisely, this functional group allows embodiments of the present disclosure to adapt by tuning or optimizing certain system parameters according to location engine 139 location estimate accuracy and reliability.Get this from a library! Yearn for certainty. [William Hooker, (Drummer); David Soldier; William Hooker Trio,].Random loc sigs are obtained, for example, from verifying a previously unknown target MS location once the MS 140 has been located.For example, for some MSs 140 there may be an associated or dedicated device for each such MS that allows the MS to function as a cordless phone to a line based telephone network when the device detects that the MS is within signaling range.The 1987 Treaty between the United States of America and the Union of Soviet Socialist Republics on the Elimination of their Intermediate-Range and Shorter-Range.For example, the FOMs may be object methods on an MS location estimator object, wherein the estimator object receives substantially all target MS location signal data output by the signal filtering subsystem.Since each location hypothesis includes both an MS location area estimate and a corresponding confidence value indicating a perceived confidence or likelihood of the target MS being within the corresponding location area estimate, there is a monotonic relationship between MS location area estimates and confidence values.
Free Space Path Loss (L p ) Slow fading loss or margin (L slow ) Fast fading loss or margin (L fast ).From the BS 122 perspective, it is preferred that the strongest first four CDMA delay spread fingers and the mobile station power level be collected and sent to the location system 42, for each of preferably three BSs 122 which can detect the mobile station 140.
Such parameters can be used as weighting factors that influences the degree the system optimizes for accuracy versus network compactness.An embodiment of the present disclosure employs a number of distinctly different location computational models for location which provides a greater degree of accuracy, robustness and versatility than is possible with existing systems.Further, by providing each location base station (LBS) with a co-located stationary wireless transceiver (denoted a built-in MS above) having similar functionality to an MS, the following advantages are provided.Accordingly, to accomplish a tuning of such system parameters, an adaptation engine is included in at least one embodiment of the present disclosure for automatically adjusting or tuning parameters used.Each CDMA signal corresponds to an unambiguous pseudorandom binary sequence for modulating the carrier signal throughout a predetermined spectrum of bandwidth frequencies.However, as the population density increases and the radio signaling environment becomes cluttered by, for example, thermal noise and multipath, additional or alternative FOMs may be transferred via the network to the location center for the municipality.Note that in computing the most likely target MS location estimate a plurality of location hypotheses may be taken into account.THE INDEFECTIBILITY OF THE CATHOLIC CHURCH.
