From d6da809d2fe35a00e03b0ae1422536245acd28be Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sun, 30 Jul 2017 16:03:32 +0200 Subject: TRX / VIRT-PHY: Make check for BCCH/CCCH more specific In bts_model_l1sap_down() we want to identify BCCH/CCCH channel numbers, but our check is a bit non-specific. Let's make the check more specific to only cover the BCCH, Uplink CCCH and Downlink CCCH C-bits as defined n 3GPP TS 08.58 Section 9.3.1 Change-Id: Ia20ab09b96c87c0dfbfaf98e5b2a8d36423fac67 --- src/osmo-bts-virtual/l1_if.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/osmo-bts-virtual') diff --git a/src/osmo-bts-virtual/l1_if.c b/src/osmo-bts-virtual/l1_if.c index 4fe1ec8f..bdbf2a70 100644 --- a/src/osmo-bts-virtual/l1_if.c +++ b/src/osmo-bts-virtual/l1_if.c @@ -370,7 +370,7 @@ int bts_model_l1sap_down(struct gsm_bts_trx *trx, struct osmo_phsap_prim *l1sap) /* we receive a channel activation request from the BSC, * e.g. as a response to a channel req on RACH */ if (l1sap->u.info.type == PRIM_INFO_ACTIVATE) { - if ((chan_nr & 0x80)) { + if ((chan_nr & 0xE0) == 0x80) { LOGP(DL1C, LOGL_ERROR, "Cannot activate" " chan_nr 0x%02x\n", chan_nr); break; @@ -419,7 +419,7 @@ int bts_model_l1sap_down(struct gsm_bts_trx *trx, struct osmo_phsap_prim *l1sap) 0); break; } - if ((chan_nr & 0x80)) { + if ((chan_nr & 0xE0) == 0x80) { LOGP(DL1C, LOGL_ERROR, "Cannot deactivate " "chan_nr 0x%02x\n", chan_nr); break; -- cgit v1.2.3
