Method for controlling communication transfers of mobile equipments (UEi) between wireless access networks (WNj) having different access technologies, comprising the steps: i) when a communication established by a mobile equipment (UEi) through a first wireless access network is candidate to be transferred by the mobile equipment (UEi) to an access equipment of a second wireless access network, • running a load-balancing algorithm with at least a value of a parameter, representative of said communication into said first wireless access network, and at least an estimate of the value of said parameter if said communication was established through said access equipment of said second wireless access network, at least one other mobile equipment (UEi') having already established an other communication through said access equipment of said second wireless access network, to determine if said communication can be transferred depending on at least one rule, • running the load-balancing algorithm with an estimate of the impact of a parameter value representative of said other communication of the at least one other mobile equipment (UEi') into said second wireless access network, if the communication of the mobile equipment (UEi) established through the first wireless access network is transferred to said second wireless access network, and, ii) outputting a message representative of the result of said transfer determination. i) when a communication established by a mobile equipment (UEi) through a first wireless access network is candidate to be transferred by the mobile equipment (UEi) to an access equipment of a second wireless access network, • running a load-balancing algorithm with at least a value of a parameter, representative of said communication into said first wireless access network, and at least an estimate of the value of said parameter if said communication was established through said access equipment of said second wireless access network, at least one other mobile equipment (UEi') having already established an other communication through said access equipment of said second wireless access network, to determine if said communication can be transferred depending on at least one rule, • running the load-balancing algorithm with an estimate of the impact of a parameter value representative of said other communication of the at least one other mobile equipment (UEi') into said second wireless access network, if the communication of the mobile equipment (UEi) established through the first wireless access network is transferred to said second wireless access network, and, • running a load-balancing algorithm with at least a value of a parameter, representative of said communication into said first wireless access network, and at least an estimate of the value of said parameter if said communication was established through said access equipment of said second wireless access network, at least one other mobile equipment (UEi') having already established an other communication through said access equipment of said second wireless access network, to determine if said communication can be transferred depending on at least one rule, • running the load-balancing algorithm with an estimate of the impact of a parameter value representative of said other communication of the at least one other mobile equipment (UEi') into said second wireless access network, if the communication of the mobile equipment (UEi) established through the first wireless access network is transferred to said second wireless access network, and, ii) outputting a message representative of the result of said transfer determination.
