A system and a method for controlling access at a user end are disclosed. The correlation between a tag signal of a femtocell access point and a tag signal of a fixed internet device is established, such that when the femtocell access point would access internet via the fixed internet device, a tag signal of the femtocell access point and a tag signal of the fixed internet device are acquired, so as to determine whether the tag signal of the femtocell access point and the tag signal of the fixed internet device match the correlation in the data bank. When the tag signal of the femtocell access point and the tag signal of the fixed internet device match the correlation, the femtocell access point is allowed to provide access services. The present invention provides an effective mechanism for controlling access at a user end.
