Abstract: A method of performing a random access channel (RACH) procedure between a mobile terminal and a network includes the steps of detecting whether a random access response (RAR) is received from the network within a certain time period, the RAR including information about a random access channel (RACH) preamble transmitted to the network; and if the RAR is not received within the certain time period or if the information about the transmitted RACH preamble included in the RAR does not match the transmitted RACH preamble, performing a first procedure to detect failures in the RACH procedure; and if the RAR is received within the certain time period and if the information about the transmitted RACH preamble included in the RAR matches the transmitted RACH preamble, performing a second procedure to detect failures in the RACH procedure.

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.
