A handover control method includes the follow steps. First, determining a geographical location of each femtocell and determining a maximum bandwidth provided by each femtocell, and determining which femtocells are in a same region according to the geographical information of each femtocell. Secondly, selecting one or more femtocells from one region as server femtocells of the region by comparing the maximum bandwidth of the femtocells in the same region, and transmitting identification information of each server femtocell to non-server femtocells near the server femtocell. Thirdly. transmitting registration information of all other femtocells of all regions to each server femtocell. Fourthly, when receiving a handover report from user equipment to switch from an original femtocell to a target femtocell, obtaining the registration information of the target femtocell from one server femtocell. Finally, transmitting a control signal including the obtained registration information to the user equipment.
