    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: 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: A multimedia broadcast/multicast service (MBMS) in a universal mobile telecommunications system (UMTS) includes a UTRAN that provides an MBMS service. The MBMS service-related information is exchanged between the UTRAN and a terminal or between nodes in the UTRAN by using an MBMS identification so that a user group receiving MBMS data or a data of a specific MBMS service can be identified.

    Abstract: A cell selection method where, if a hierarchical cell structure (HCS) is used, a first ranking procedure is performed if the UE has low mobility, and a second ranking procedure is performed if the UE has high mobility. When the UE has low mobility, the first ranking procedure is performed for all measured cells that have a highest HCS priority among those cells that fulfill a criterion S and a criterion H≧0, or the ranking procedure is performed for all measured cells regardless of HCS priorities if no cell fulfills the criterion S and the criterion H≧0. When the UE has high mobility, the second ranking procedure is performed for all measured cells, and if there are cells with lower HCS priority than the serving cell that fulfills the criterion S and the criterion H≧0, the ranking procedure is performed for all cells that have the highest HCS priority.
