ARRANGEMENTS IN A MOBILE TELECOMMUNICATIONS NETWORK

摘要

The present invention relates to a method and arrangements for providing an estimation of a cell radius in a mobile telecommunications network. The arrangement comprises means for estimating the path loss by using an arbitrarily path loss estimation method wherein a at least a pre-defined cell radius is used as input. The use of the arbitrarily path loss estimation method results in a path loss data file comprising values associated with the signal strength for pixels within the cell defined by the first cell radius. The arrangement is characterised in that it further comprises means for estimating a first updated cell radius by excluding pixels having a signal strength below a predetermined threshold from the cell area having the pre-defined cell radius, wherein the first updated cell radius is the cell radius of the remaining cell area when said pixels are excluded.
