Abstract

A method for parking a mobile communication apparatus of a femtocell base station and applicable to a communication network including a core of an apparatus network, the femtocell base station, and the mobile communication apparatus. The femtocell base station obtains a RRC connection request of an international mobile station identity (IMSI) of the mobile communication apparatus and compares the obtained IMSI with the IMSIs in a mobile communication apparatus authority list created in the femtocell base station. Once the mobile communication apparatus enters a communication area covered by the femtocell base station, the femtocell base station will determine whether the mobile communication apparatus is authorized to park the communication area or not. Unauthorized subscribers are rejected before the femtocell base station is established the communication relation with the core of the apparatus network, thereby saving network resource and speeding up rejection.
