System and method for mobile location using ranked parameter labels

摘要

A system and method for generating a calibration database in a communications network. A grid of geographic locations may be generated to cover a region in a communications network having a plurality of cellular sites. A set of network measurement reports (NMRs) is generated for the region, the NMR being a collection of measurement parameters observed at selected geographic locations in the grid. A label may then be generated representing a first measurement parameter observed from ones of the plural cellular sites at one of the selected geographic locations, the label including a relative ranking by cellular site of the first measurement parameter. Using this generated label, a calibration database for the communications network may be populated and locations of mobile devices determined therefrom.

1. A method of generating a calibration database in a communications network comprising the steps of:
(a) generating a grid of geographic locations to cover a region in a communications network having a plurality of cellular sites; (b) generating a set of network measurement reports (NMRs) for the region, the NMR being a collection of measurement parameters observed at selected geographic locations in the grid; (c) generating a label representing a first measurement parameter observed from ones of the plural cellular sites at one of the selected geographic locations, the label including a relative ranking by cellular site of the first measurement parameter; and (d) populating a calibration database for the communications network using the generated label, wherein at least two rankings of sites in the label are of equal rank, and dividing the label having equal ranked sites into two columns, each of the two columns having the same ranking of respective sites but with the two equal ranking sites transposed in the two columns.
