Methods, apparatuses, computer programs and computer program products for load balancing

A method for balancing load between a source base station and a target base station, the method comprising:

• receiving a first load value (LV1) transmitted by the target base station, wherein LV1 is an admission threshold value for the target base station;
• receiving a second load value (LV2) transmitted by the target base station, wherein LV2 is a value indicating the current load on the target base station;
• calculating a corrected load value (Corr_lv) using on one or both of LV1 and LVC2 and a set of one or more predetermined parameters;
• and
• determining, using the corrected load value, an amount of load to shift from the source base station to the target base station.

An apparatus for determining corrected load values, the apparatus being adapted to:

• obtain a set of input features, each input feature in the set of input features being one of:
• i) a reported load value that was reported by a target base station to a source base station and ii) a derived load value that was derived using the reported load value;
• obtain a set of output features, each output feature in the set of output features being a determined load value that was determined by the source base station, wherein each output feature included in the set of output features is associated with a single one of the input features included in the set of input features;
• and
• determine, using the set of input features and the set of output features, a set of one or more parameters for a mathematical model for determining a corrected load value based on one or more load values provided by the target base station.
