Abstract: According to one embodiment, a method for maintaining a communication between a mobile terminal and a network in a mobile communication system includes: determining whether a state of the mobile terminal is in an unsynchronized state while maintaining a radio resource control (RRC) connected state with the network; performing a random access channel (RACH) procedure for a synchronized state if it is determined that the state of the mobile terminal is in the unsynchronized state while maintaining the RRC connected state with the network; and after performing the RACH procedure, transitioning from the synchronized state to the unsynchronized state with the network while maintaining the RRC connected state with the network when a timer expires.

Abstract: With respect to generating and sending a MAC PDU by using the radio resources allocated to the mobile terminal, the level of priority between the buffer status report (BSR) and the established logical channels are defined such that the data of each logical channel and buffer status report can be more effectively, efficiently and quickly transmitted.

Abstract: An apparatus and method for performing procedures (protocols) of a PDCP (Packet Data Convergence Protocol) layer and an RLC (radio layer in an E-UMTS (Evolved Universal Mobile Telecommunications System) which has evolved from UMTS, among radio protocols of a mobile communication system. The PDCP layer performs ciphering on data (i.e., PDCP SDU) received from an upper layer, generates an indicator discriminating ciphered data and non-ciphered data (i.e., an ROHC feedback packet directly generated by the PDCP layer), and transmits the same to a lower layer (i.e., MAC layer). A PDCP SN (Sequence Number) is defined as an algorithm for ciphering the data in the PDCP layer to perform ciphering in the PDCP layer.

Abstract: In a wireless mobile communications system, a method for controlling a radio resource allocation is provided. A network transmits access control information to a terminal such that a request for the radio resource allocation which will be transmitted from the terminal can be controlled. The terminal selectively transmits the request for the radio resource allocation based on the received information, thus a transmission of an unnecessary request for the radio resource can be minimized, thereby preventing a waste of the radio resource.
