pespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/41755?usp=email ) Change subject: library/NGAP_Emulation: Route Paging through NGAP_UNIT ...................................................................... library/NGAP_Emulation: Route Paging through NGAP_UNIT The Paging message has no amf_ue_id/ran_ue_id, hence it's a non-ue message. Route it over NGAP_UNIT; ConnHdlr can then use the f_create_ngap_expect_proc() function to get a copy of it.
