TIVE. Hence the Resume message can provide additional UE configuration. 9. Upon successfully processing the RRC Resume message, the UE enters RRC CON- NECTED. 10. The Xn-AP XN-U ADDRESS INDICATION message is used to provide the previous gNB with the address of the new gNB to forward data to. 11. The AMF is updated with the new gNB address with the NG-AP PATH SWITCH REQUEST message. 12. The AMF responds with the NG-AP PATH SWITCH RESPONSE message. 13. Upon successful completion of the resumption, the UE context in the previous gNB is released using the Xn-AP UE Context Release message. If the resume request cannot be successfully processed by the gNB, for example if the UE context cannot be retrieved, a fallback procedure to a connection setup similar to the one discussed above for reestablishment is used. Similar to the tracking area concept in the CN, an RNA is used in INACTIVE to keep track of the UE's location. Consequently, the UE performs an RNA update when crossing an RNA boundary. When downlink data arrives at the gNB for a UE in INACTIVE state, the gNB will trigger a RAN originated Paging message to the cells of the RNA. The UE, upon receipt of the Paging message, will initiate a transition to CONNECTED state using the RRC Resume Request message. The UE also continues to perform CN tracking area updates while in INACTIVE. 3.4.5.2.7 Broadcast Information System Information Broadcast (SIB) is primarily used to provide configuration information required for IDLE UEs to make an initial access to the network. The main components of the broadcast information are: 3.4 NR Protocol Stack Master information block (MIB), also called Minimum System Information (MSI), which provides information about the cell and how to acquire SIB1. SIB1, also called Remaining Minimum System Information (RMSI), which contains information necessary for UE to decide whether it can camp on and to initiate access in the cell. It also contains information about how to acquire the rest of the SIBs. Other SIBs (from SIB2 to SIB9 at the time
