Claim Text:
1. An apparatus for determining a position of a terminal, said apparatus comprising: a processor, and a memory, said memory storing a program comprising program code, said memory and said program configured to, with said processor, cause said apparatus, when said program is executed on said processor, to perform checking whether an intersection of all areas of a set of areas that are associated with one or more communication nodes and represent and/or limit possible positions of a terminal is potentially non-empty, wherein each of said areas represents a coverage area of a communication node, wherein each of said areas is associable with a respective bounding box that is one of a rectangle and a rectangular cuboid, wherein said intersection is defined to be potentially non-empty when an intersection of all of said bounding boxes would be non-empty, and further configured to cause said apparatus, when said program is executed on said processor, to perform determining a position of said terminal in dependence on a result of the checking whether said intersection of all areas of said set of areas is potentially non-empty, wherein said determining said position of said terminal is performed by determining a focus area and by determining said position of said terminal based on said focus area, wherein said position of said terminal is determined based on a weighted sum of positions that are distributed within said focus area, and wherein at least an initially used definition of weights to be multiplied by said positions in said weighted sum of positions depends on said result of said checking whether said intersection of all areas of said set of areas is potentially non-empty.
