Method for controlling communication transfers of mobile equipments between wireless access networks having different access technologies, based on a load- balancing

A control device (D) is intended for working for an access equipment (AP2) of a wireless access network (WN2) that belongs to a communication infrastructure, which further comprises at least one other wireless access network (WN1) having an access technology different from the one of the wireless access network (WN2). This control device (D) is arranged, when a mobile equipment (UE1) could transfer a communication, established through the other wireless access network (WN1), to the access equipment (AP2), i) for feeding a load-balancing algorithm with at least a value of a parameter, representative of this communication into the other wireless access network (WN1), and at least an estimate of the value that would take this parameter if this communication was established through the wireless access network (WN2), in order it determines if this communication can be transferred depending on at least one rule, and ii) for outputting a message representative of the result of this transfer determination.
