Abstract:
A method (100) of determining spatial distribution of traffic volume within respective radio cells (RC1 . . . ) of a cellular mobile radio communications network (MRN) with a plurality of base stations (BS1, BS2, BS3), which each serve a respective one of the radio cells (RC1, RC2, RC3), the method comprising the steps of:determining (130), for each mobile station (MS) within the radio cell (RC1), at least two measured values (M1, M2) which depend on lengths of respective radio transmission paths from the mobile station (MS) to said at least two base stations (BS1, BS2), wherein the radio cell (RC1) is subdivided into several sections (A1, A2, A3, . . . B1, B2, . . . ) wherein with each section (C2) there is associated a reference data set (DS) comprising at least two reference values (RL1, RL2) which specify, for spatial coordinates of the section (C2), radio propagation requirements for radio transmission paths to at least two of the base stations (BS1, BS2), said reference values being characteristic of respective spatial separations from the section (C2) to the at least two base stations (BS1, BS2);forming (140) from the measured values (M1, M2) an actual data set (DS'), comparing said actual data set with the reference data sets (DS), wherein each of said reference data sets (DS) is associated with exactly one of the sections (A1, A2, A3, . . . B1, B2, . . . );determining (150) which section (C2) has a reference data set (DS) which most closely matches the actual data set (DS') ; and incrementing (160), for the matching section (C2), a counter state (CNT) which represents traffic volume in the matching section (C2).
