Patent ID: 8880072

Claim:
A method for measuring a neighbor base station in a wireless communication system by a User Equipment (UE) to access the neighbor base station, the method comprising: receiving, from a femto base station, a message comprising neighbor base station information of the femto base station; generating a neighbor base station information list of the femto base station based on the neighbor base station information; determining whether information of the neighbor base station is present in the neighbor base station information list; when the information of the neighbor base station is present in the neighbor base station information list and when accessing the neighbor base station of the femto base station based on the generated neighbor base station information list, determining whether a frequency of the femto base station is different from a frequency of the neighbor base station; when the frequency of the femto base station is different from the frequency of the neighbor base station, requesting to allocate a measurement gap by sending a proximity indication to the femto base station; receiving an allocation of the measurement gap from the femto base station to measure the neighbor base station; and measuring the neighbor base station based on the allocated measurement gap.
