1. A method in a cellular radio communication network for determining a monitored set from a list of neighboring cells to each of at least a first and a second active cell in an active set of such cells for a user equipment in said network, said first and second active cell together with the associated neighboring cells being ranked according to signal quality of said active cells in the active set, said method comprising the steps of:
a) considering a first member in said neighboring list associated with the active cell in said active set having the best quality;
b) including said first member in said monitoring list if not already a member in said list;
c) consider a first member of next lower ranked cell in said active set for selection if not considered before; while if said first member of next lower ranked cell in said active set has been considered,
d) consider the next member in said neighboring list associated with the cell in said active set having the best quality; and
e) continuing selecting cells according to steps a)–c) until said monitored set has reached its maximum size.
