From 179ddef0f14513719ec302352bcfe995e129f1ae Mon Sep 17 00:00:00 2001 From: Pau Espin Pedrol Date: Thu, 11 Feb 2021 16:03:46 +0100 Subject: pcu: Introduce several tests TC_nacc_outbound_pkt_cell_chg_notif_twice* These tests verify the NACC FSM adapts to MS restarting the NACC procedure at any point when it selects for another tgt cell.
