transmit an access point traffic load parameter (ATT) indicative of said access point traffic load to said at least one network station (5, 6); and
said at least one network station (5, 6) is arranged to;
monitor its network station traffic load;
store a network station traffic load parameter (AUTT) indicative of said network station traffic load;
receive access point traffic load parameters (ATT) from said plurality of access points (AP1, AP2, AP3); and
select a communication connection with one of said plurality of access points (AP1, AP2, AP3) using a predetermined cost function taking at least said access point traffic load parameters (ATT) and said network station traffic load parameters (AUTT) into account.
