Abstract
Official abstract text for this publication.
An apparatus, method and computer program storage device cooperate to provide a quality position estimation of a mobile communication device by determining a reference area. The reference area includes the position of the mobile communication device as well as a plurality of transmitters. Transmitters that are detected as being outside of the reference area are excluded from contributing to the position estimate. The reference area is centered at a standard position, which may be a previous position or a GPS based position, for example. The range of the reference area includes a component that considers the range of a transmitter, as well as a GPS error or an estimated move distance of the mobile communication device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A position estimation apparatus, comprising: a reference area determining unit configured to determine a reference area that includes a position of a mobile communication station, and a position estimation unit configured to estimate the position of said mobile communication station based on position information of a plurality of transmitters within said reference area, wherein the reference area is defined by a radius and a center point, the radiu…
