A method performed by a network node for handling load balancing of at least one User Equipment, UE, (121, 122, 123, 124), which at least one UE (121, 122, 123, 124) has performed a respective handover to a Second Frequency, F2, carrier provided by the network node in a communication within a wireless communication network, the method comprising: evaluating whether or not each of the at least one UE (121, 122, 123, 124) has resided at the F2 carrier for a respective time period which is below a first threshold value, when any one or more first UEs (121, 122) out of the at least one UE (121, 122, 123, 124) have resided at the F2 carrier for a respective time period which is below the first threshold value deciding that the one or more first UEs (121, 122) shall be put through a further evaluation for load balancing, before being chosen as a candidate for load balancing, when any one or more second UEs (123, 124) out of the at least one UE (121, 122, 123, 124) have resided at the F2 carrier for a respective time period which is not below the first threshold value, deciding that each of the one or more second UEs (123, 124) is a candidate for load balancing, performing the further evaluation of the one or more first UEs (121, 122) for load balancing, which further evaluation comprises: when all of the first UEs (121, 122) cannot be substituted by second UEs (123, 124) for load balancing, deciding that the one or more first UEs (121, 122) shall be put through a yet further evaluation for load balancing before it is decided whether they should be identified as load balancing candidates, when all of the one or more first UEs (121, 122) can be substituted by second UEs (123, 124) for load balancing, replacing all of the one or more first UEs (121, 122) with second UEs (123, 124) as candidates for load balancing and deciding that all of the one or more first UEs (121, 122) are not candidates for load balancing. evaluating whether or not each of the at least one UE (121, 122, 123, 124) has resided at the F2 carrier for a respective time period which is below a first threshold value, when any one or more first UEs (121, 122) out of the at least one UE (121, 122, 123, 124) have resided at the F2 carrier for a respective time period which is below the first threshold value deciding that the one or more first UEs (121, 122) shall be put through a further evaluation for load balancing, before being chosen as a candidate for load balancing, when any one or more second UEs (123, 124) out of the at least one UE (121, 122, 123, 124) have resided at the F2 carrier for a respective time period which is not below the first threshold value, deciding that each of the one or more second UEs (123, 124) is a candidate for load balancing, performing the further evaluation of the one or more first UEs (121, 122) for load balancing, which further evaluation comprises: when all of the first UEs (121, 122) cannot be substituted by second UEs (123, 124) for load balancing, deciding that the one or more first UEs (121, 122) shall be put through a yet further evaluation for load balancing before it is decided whether they should be identified as load balancing candidates, when all of the one or more first UEs (121, 122) can be substituted by second UEs (123, 124) for load balancing, replacing all of the one or more first UEs (121, 122) with second UEs (123, 124) as candidates for load balancing and deciding that all of the one or more first UEs (121, 122) are not candidates for load balancing. when all of the first UEs (121, 122) cannot be substituted by second UEs (123, 124) for load balancing, deciding that the one or more first UEs (121, 122) shall be put through a yet further evaluation for load balancing before it is decided whether they should be identified as load balancing candidates, when all of the one or more first UEs (121, 122) can be substituted by second UEs (123, 124) for load balancing, replacing all of the one or more first UEs (121, 122) with second UEs (123, 124) as candidates for load balancing and deciding that all of the one or more first UEs (121, 122) are not candidates for load balancing.
