A method of providing a call transfer service and a mobile terminal using the same are provided. When a call connection request signal transmitted to a mobile communication server through a PSTN is received, any one of previously stored phone numbers is selected and a service of transferring a call to the selected phone number according to the received call connection request signal is requested. Therefore, when call connection is requested, it is selected whether a call is to be transferred, when a call is transferred, a phone number to transfer a call can be dynamically selected according to a user situation, and thus user convenience according to call transfer can be improved.

There is provided an apparatus for generating a mean value of N-bit input data in M-bit operations (M and N are integers, and M is greater than N) by dividing a total sum of the input data by number of times the data are input, including a ROM (Read Only Memory) storing therein, as denominators, quotients of dividing 2M-N by integers in a range from one to a maximum allowable number of times for data input. Further, ROM addresses of the denominators are determined based on the integers.

A modulo N calculating method for an M1*M2-bit binary integer, wherein N, M1 and M2 are integers, includes the steps of dividing the M1*M2-bit binary integer into M1 bits and performing AND operation on each M1 bits and a specific binary integer; and changing a value of an output register depending on the AND operation result and storing the value thereto. A modulo N calculating apparatus includes an input unit for receiving an M1*M2-bit binary integer, wherein N, M1 and M2 are integers; and an AND operation unit for performing AND operation on the M1*M2-bit binary integer and a specific binary integer. Furthermore, when the M1 and the N may be 4 and 3, respectively, the specific binary value may be 1010 or 0101.

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.

Provided is a ghost register processing apparatus and method. The ghost register processing apparatus may include a ghost setting determining unit to determine whether a ghost is set with respect to a caller identification (ID) that is received in response to a call request or a message reception and a reception information controller to store reception information associated with the caller ID in a ghost memory unit when the determining determines that the ghost is set.
