Appratus and method for connectiong radio link in a wireless communication system having private network cell

A radio link connection apparatus and a method thereof in a wireless communications system having a personal area network cell are provided to improve communication service quality by selecting a cell in the wireless communications system which the cell of different size is overlapped. If a terminal(421) selects an individual cell(411) or performs handover, the terminal stores radio link connection information about public cell(401) which the individual cell is overlapped. The terminal stores the radio link connect information about the public cell overlapped in the individual cell. The radio link connect information is acquired through signaling from network or measurement of the terminal. A timer(T1) which is set up as the predetermined temporal value starts operation. The terminal inspects whether the timer is terminated. If the timer is terminated, the terminal performs an operation along a left/right path.
