Abstract: A method for encoding a broadcast channel protocol data unit (BCH PDU) based on a broadcast control channel (BCCH) scheduling error in a universal mobile telecommunications system (UMTS) having a Node B and a radio network controller includes setting up a call between the radio network controller and the Node B to receive system information and scheduling information for a system information update from the radio network controller; initializing broadcast channel protocol data units and control information for every system frame number (SFN) at the Node B; and detecting the broadcast control channel scheduling error on the scheduling information for the system information update based on segment types of the system information when combining the system information for every system frame number. In case the broadcast control channel scheduling error is not detected, the broadcast channel protocol data units are encoded to be incorporated therein the system information.
