imited period of time, the source eNB maintains the UE context to allow the UE to return in case of handover failure. If handover failure is detected, the UE will attempt to resume the RRC connection, either with the source eNB or with another cell using the RRC re-establishment procedure. The connection re-establishment would succeed if the accessed cell is prepared. The paging procedure is used to transmit paging information to a UE in RRC_IDLE and/or to inform mobile terminals in RRC_IDLE and RRC_CONNECTED states about a system information change and/or to inform about ETWS primary and/or secondary notifications. The paging information is provided to upper layers, which in response may establish an RRC connection to receive an incoming call. The E-UTRAN initiates the paging procedure by transmitting the paging message at the user equipment's paging intervals. The E-UTRAN may address multiple mobile terminals within Hyper Frame Number (HFN) is an overflow counter mechanism that is used in the eNB and UE in order to limit the actual number of sequence number bits that are needed to be sent over the radio air interface. The HFN needs to be synchronized between the UE and eNB. CHAPTER 6 The IEEE 802. 16m MAC CPS (Part I) a paging message by including one PagingRecord for each UE. The E-UTRAN may also indicate a change of system information and/or provide an ETWS notification. The RRC connection establishment involves SRB1 establishment. The procedure is also used to transfer the initial NAS dedicated information/message from the UE to the E-UTRAN. The UE initiates the RRC connection establishment procedure when the upper layers request establishment of an RRC connection while the UE is in the RRC_IDLE state. The RRC connection re-establishment is used to re-establish the RRC connection, including resumption of SRB1 operation and reactivation of security. A UE in RRC_CONNECTED, for which security has been activated, may initiate the procedure in order to continue the RRC connection. The connection re-establishment
