A handover control method for handover of a mobile station from a serving cell to a neighbour cell , comprising: determining (S13) initiation of the handover by using different handover initiation conditions and different hold times depending on a radio quality (QS) of the serving cell at a position of the mobile station , wherein: the determining includes determining (S13) initiation of the handover in response to detecting satisfaction of a first state (S11) in which a period during which a first handover initiation condition continues to be satisfied exceeds a first hold time (TTT1) while the radio quality (QS) of the serving cell is equal to or lower than a first level, or detecting satisfaction of a second state (S12) in which a period during which a second handover initiation condition continues to be satisfied exceeds a second hold time (TTT2) while the radio quality (QS) of the serving cell is equal to or greater than a second level, wherein the second level is higher than the first level, the second hold time (TTT2) is longer than the first hold time (TTT1), characterized in that : the first handover initiation condition includes the radio quality (QS) of the serving cell being lower than a first threshold (TH1) and a radio quality (QN) of the neighbour cell being higher than a second threshold (TH2), and the second handover initiation condition includes the radio quality (QN) of the neighbour cell being higher than a third threshold (TH3), or includes the radio quality (QN) of the neighbour cell being higher than the radio quality (QS) of the serving cell by more than a fourth threshold (TH4). the determining includes determining (S13) initiation of the handover in response to detecting satisfaction of a first state (S11) in which a period during which a first handover initiation condition continues to be satisfied exceeds a first hold time (TTT1) while the radio quality (QS) of the serving cell is equal to or lower than a first level, or detecting satisfaction of a second state (S12) in which a period during which a second handover initiation condition continues to be satisfied exceeds a second hold time (TTT2) while the radio quality (QS) of the serving cell is equal to or greater than a second level, wherein the second level is higher than the first level, the second hold time (TTT2) is longer than the first hold time (TTT1), characterized in that : the first handover initiation condition includes the radio quality (QS) of the serving cell being lower than a first threshold (TH1) and a radio quality (QN) of the neighbour cell being higher than a second threshold (TH2), and the second handover initiation condition includes the radio quality (QN) of the neighbour cell being higher than a third threshold (TH3), or includes the radio quality (QN) of the neighbour cell being higher than the radio quality (QS) of the serving cell by more than a fourth threshold (TH4). the first handover initiation condition includes the radio quality (QS) of the serving cell being lower than a first threshold (TH1) and a radio quality (QN) of the neighbour cell being higher than a second threshold (TH2), and the second handover initiation condition includes the radio quality (QN) of the neighbour cell being higher than a third threshold (TH3), or includes the radio quality (QN) of the neighbour cell being higher than the radio quality (QS) of the serving cell by more than a fourth threshold (TH4). <EOS>
