5G - Initial access and Registration procedure (Part of 5G course - Link in description)

**LINK of 5G Complete Course - https://www.itelcotech.com/learningpa... 5G: Initial access and Registration procedure User needs to register with the network to receive services, to enable mobility tracking and reachability. When UE powers ON, following procedure takes places at radio end:- · Initial access consists of cell search and acquisition to first allow a UE to synchronize with the target cell. Primary sync signal (PSS) and Secondary sync signal (SSS) helps to establish DL sync. · Master Information Block (MIB) from NR helps UE to acquire the information needed to access the network. · System information block (SIB) in DL includes configurations for the UE such as cell selection & re-selection, random access parameters, PLMN identity and access class barring list. Once all criterions are met, cell is selected by UE. · Initial access from UE to NR starts from Random Access procedure. NR decodes the preamble and UL sync is performed. · Radio resource control (RRC) is setup and then an initial NAS message establish a signaling connection between UE and AMF. Further interactions among network functions in the 5GC are captured below in the attachment.
