Abstract: Disclosed is a radio (wireless) communication system providing a radio communication service and a terminal, and more particularly, to a method of effectively detecting and handling endless RLC retransmission so as to prevent endless RLC re-transmission occurring between the terminal and a network in an Evolved Universal Mobile Telecommunications System (E-UMTS) that has evolved from a Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system.

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: 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.
