2021-01-12	hodec2: fix congestion oscillation bug	Neels Hofmeyr	1	-5/+2
	When evenly distributing congestion across cells, count the number of occupied lchans surpassing congestion, and not the overall number of free lchans -- which disregards congestion thresholds. Fix the bugs shown by test_congestion_no_oscillation.ho_vty test_balance_congestion_tchf_tchh.ho_vty This implements a simple calculation for congestion load by counting lchans in use above congestion. An improvement of this calculation using percent follows in I55234c6c99eb02ceee52be0d7388bea14304930f. Related: SYS#5259 Change-Id: Icb373dc6bfc9819446db5e96f71921781fe2026d
2021-01-11	handover_test: show a bug: add test_congestion_no_oscillation.ho_vty	Neels Hofmeyr	1	-0/+31
	Also add test_congestion_no_oscillation2.ho_vty which is an almost identical scenario that does not show the bug -- because it has two more TCH/H available in BTS 1, showing the strange behavior of the algorithm. Related: SYS#5259 Change-Id: Idf88b4cf3d2f92f5560d73dae9e59af39d0494c0
