Draft: Implement NR-UE Deregistration procedure (!2008) · Merge requests · oai / openairinterface5G

Robert Schmidt requested to merge deregistration into develop Mar 13, 2023

UE 5G NAS: add deregistration request message
Reimplement ITTI wait mechanism using semaphores instead of signals (which are not safe to be used in signal handlers) and allows to override the signal handler
nrUE: send deregistration message on first ^C, will stop automatically if RRC release received; second ^C force-stops
Refactor of 5G UE NAS: one common structure for 5G NAS info instead of multiple (uicc_t, ue_sa_security_key_t), remove useless module ID, put duplicated code into separate functions...
Fix bug: add NAS message counters instead of hardcoding
