Claim Text:
1. A method for managing a terminal operating in an idle state, the method comprising: entering, by the terminal operating in the idle state, a femto cell; determining, by the terminal operating in the idle state, whether a femto base station managing the femto cell has the same paging group as a macro base station managing a macro cell overlapping the femto cell; transmitting, by the terminal operating in the idle state, a first ranging code, triggering the femto base station to enter a paging enable state, to the femto base station before an idle mode timer ends if it is determined that the paging group is the same; transmitting, by the terminal operating in the idle state, a second ranging code for a location update after the idle mode timer ends if it is determined that the paging group is the same; transmitting, by the terminal operating in the idle state, the second ranging code for the location update to the femto base station before the idle mode timer ends if it is determined that the paging group is not the same; and receiving, by the terminal operating in the idle state, a paging message from the femto base station in the paging enable state, wherein the femto base station starts the paging enable state according to the first ranging code and the second ranging code received before the idle mode timer ends.
