Claim of US Patent No. 10,386,450

1. An apparatus configured to locate a radio unit relative to a plurality of anchor nodes, the anchor nodes being radio units with known locations, wherein the apparatus comprises:an identification unit for receiving identification information of selected anchor nodes and respective signal strength or quality information of radio links between the radio unit to be located and the selected anchor nodes, and for identifying hyper zones of intersecting types for each of the selected anchor nodes, wherein hyper zones of a respective type extend along one respective direction out of a plurality of different directions, each hyper zone comprising at least two of the anchor nodes;
a selection unit for calculating for each of the identified hyper zones an allocated single hyper-zone signal strength or quality based on the received respective signal strength or quality information of radio links of anchor nodes belonging to the hyper zone, and for selecting a hyper zone with highest hyper-zone signal strength or quality for each type of hyper zones; and
an intersection unit for determining an intersection region of the selected hyper zones with highest hyper-zone signal strength or quality and for deriving a location information of the intersection region as the location of the radio unit to be located.
