Abstract
A method of improving co-operation between entities in a cellular mobile radio communications network, wherein during inter-cell call handover, a new server cell is chosen from a set of candidate cells as being a candidate cell to which a requested handover is possible, and candidate cells to which a requested handover is not possible are referred to as rejected cells. When executing an external call handover from a current server cell controlled by a current server entity to a new server cell chosen from the set of candidate cells and controlled by a new server entity which is distinct from the current server entity, the new server entity is informed of any previously rejected cells.
