From c75d27acd64a8742573b9a3bf1e184f1f3b1d2cc Mon Sep 17 00:00:00 2001 From: Philipp Maier Date: Tue, 19 Oct 2021 14:43:19 +0200 Subject: BSC_Tests: set band in f_TC_fh_params_set The function f_TC_fh_params_set sets frequency hopping parameters. The ARFCN is also part of those parameters. However, this function does not set the respective band for the ARFCN that it configurs. This results in an invalid setting at the BSC that might cause unexpected behavior. Lets make sure we configure the band parameter correctly before setting the ARFCN Change-Id: I447e4145c68c62b11b818e28f0081c19e9107647 Related: SYS#5369 --- bsc/BSC_Tests.ttcn | 47 +++++++++++++++++++++++++++++++++++++++-------- 1 file changed, 39 insertions(+), 8 deletions(-) diff --git a/bsc/BSC_Tests.ttcn b/bsc/BSC_Tests.ttcn index ee4dac21..9bd9f444 100644 --- a/bsc/BSC_Tests.ttcn +++ b/bsc/BSC_Tests.ttcn @@ -8439,7 +8439,7 @@ private type record FHParamsTs { /* Hopping parameters per a transceiver */ private type record FHParamsTrx { - GsmArfcn arfcn, + GsmBandArfcn arfcn, FHParamsTs ts[8] }; @@ -8448,8 +8448,10 @@ private function f_TC_fh_params_gen(template integer tr_tn := (1, 3, 5)) runs on test_CT return FHParamsTrx { var FHParamsTrx fhp; - /* Generate a random ARFCN, including ARFCN 0 */ - fhp.arfcn := f_rnd_int(3); + /* Generate a random ARFCN in the range of 0 - 3.
