A method for providing system information (SI) by a base station in a wireless communication network is disclosed. The SI includes minimum SI and at least one other SI block. The method includes broadcasting the minimum SI having an area identification (ID) and at least one value tag, and receiving a radio resource control (RRC) message requesting the at least one other SI block from a user equipment (UE) when the area ID is different from a stored area ID on the UE or when the value tag is different from a stored value tag on the UE.
