iable and orderly transfer of information without introducing duplicates and with support for segmentation and concatenation. The RRC protocol includes the following main functions: Broadcast of system information including NAS common information, information applicable for mobile terminals in RRC_IDLE, e.g., cell (re-)selection parameters, neighbor cell information and information pertinent to mobile terminals in RRC_CONNECTED, e.g., common channel configuration information, as well as ETWS notification. RRC connection control including paging, establishment/modification/release of RRC connections (e.g., assignment/modification of UE identity (C-RNTI), establishment/modification/release of SRB1 and SRB2, access class barring, initial security activation (i.e., initial configuration of Access Stratum (AS) integrity protection and AS ciphering), RRC connection mobility (e.g., intra-frequency and inter-frequency handover, associated security handling, key/algorithm change, specification of RRC context information transferred between network nodes), establishment/modification/ release of radio bearers (RBs) carrying user data, radio configuration, and control (e.g., assignment/modification of ARQ configuration, HARQ configuration, DRX configuration), QoS control including assignment/modification of semi-persistent scheduling parameters for DL and UL, assignment/modification of parameters for UL rate control in the UE (i.e., allocation of a priority and a prioritized bit rate for each RB), and recovery from radio link failure. Inter-RAT mobility (e.g., security activation, transfer of RRC context information). Measurement configuration and reporting including establishment/modification/release of measurements (e.g., intra-frequency, inter-frequency and inter-RAT measurements), set-up and release of measurement gaps, and measurement reporting. Other functions including transfer of dedicated NAS information and non-3GPP dedicated information, transfer of UE radio access capability information, and support for E-UTRAN s
