/**
|
|
* Module brief:
|
|
* This module is used to add RRCRelease commands to the telnet server in the
|
|
* absence of full support for E2SM RAN Control (RC).
|
|
* This provides similar functionality to the ORAN.WG3.E2SM-RC-R003-v05.00
|
|
* 8.4.5.4 RRC Connection Release Control which is initiated by the RIC.
|
|
*
|
|
* Implementation notes:
|
|
* We refer to the method call rrc_gNB_generate_RRCRelease at rrc_gNB_NGAP.c
|
|
* during rrc_gNB_process_NGAP_UE_CONTEXT_RELEASE_COMMAND message generation.
|
|
*
|
|
* Building the telnetsrv and module:
|
|
* ./build_oai --build-lib telnetsrv
|
|
*
|
|
* Loading the module:
|
|
* sudo ./nr-softmodem -E --rfsim --log_config.global_log_options level,nocolor,time -O ~/gnb.sa.band78.106prb.rfsim.conf --telnetsrv --telnetsrv.shrmod rrc
