Abstract
The present invention relates to a method for adjusting handover parameters (TTT; OFF) used for handover detection within a given serving cell (CS). In accordance with an embodiment of the invention, the method comprises, for respective ones of a plurality of mobile stations (UE1 . . . UEN) served by the serving cell, gathering measurement samples (M(i,CS,k); M(i,CN,k)) of the serving cell and of a respective neighboring cell (CN) carried out by a respective mobile station (UEi) at successive time instances (k), and determining delta values (Δ(i,CN,k)) indicative of the time-indexed difference between respective ones of the measurement samples of the serving cell and corresponding ones of the measurement samples of the neighboring cell. The method further comprises determining near-optimal values (TTTNO; OFFNO) for the handover parameters by statistical characterization of the ensembles of delta values for the plurality of mobile stations. The near-optimal values may be input to an iterative closed-loop optimization algorithm in order to determine optimal values (TTTO; OFFO) for the handover parameters. The present invention also relates to a handover configuration agent (150) impl…
