ABSTRACT:
A method for determining and reporting the position of a mobile unit to a third party via a video dial tone (VDT) network is described. The method is directed for use in a wireless communication system having at least one registration area including at least one control unit and at least one base station having a corresponding coverage area. For each of the base stations in a registration area, a plurality of analog and/or TDMA RF measurements are determined, including its link budget, for a predetermined plurality of distances and directions. These measurements are modeled as scaled contoured shapes having minimum and maximum boundaries which are used to define a bounding polygon area to describe the position of a mobile station in terms of minimum and maximum error estimate. The video dial tone network includes an interactive video delivery system, a set top terminal and a video monitor.
