A method of balancing load of an individual network element operating in a pool in a radio telecommunications network. In said network a user equipment is assigned to a network element from said pool of network elements based on relative weighting values associated with said network elements. Said relative weighting value indicates the capacity of a network element relative to other network elements in the pool. The method comprises: periodically determining load of said network element; reducing the relative weighting value if said network element is overloaded for a predefined number of periods, exceeding a limit of allowed consecutive overloads.
