1. Method of load balancing in a wireless communication network, said wireless communication network comprising at least one subscriber terminal (T1, T2, T2) adapted to establish and perform a wireless communication connection in said wireless communication network, a plurality of access points (AP1, AP2, AP3) adapted to control said wireless communication connection of said at least one subscriber terminal and to exchange information with said at least one subscriber terminal, wherein one of said plurality of access points is associated with said at least one subscriber terminal, and a load control device (21;

  • 110) located outside of said subscriber terminal, said load control device being adapted to process information related to a load in said wireless communication network and to instruct roaming of said subscriber terminal from said associated one of said plurality of access points to another one of said plurality of access points, said method comprising the steps of receiving, in said subscriber terminal, access point status information (APST) determined in said plurality of access points (S10;

    S110), determining communication status information related to said plurality of access points (S20;

    S120), and processing (S20;

    S120) said received access point status information and said communication status information in order to obtain roaming support information (RSUP), processing (S40;

    S160), in said load control device, said roaming support information by an access point related load based roaming analysis and deciding (S50;

    S170), on the basis of a result of said access point related load based roaming analysis, whether said subscriber terminal is to be associated with another one of said plurality of access points, and if so, initializing (S60;

    S180) roaming of said subscriber terminal to said another one of said plurality of access points in said wireless communication network.
