From f15e647cba16267e7b1248844c70df7cf61f952d Mon Sep 17 00:00:00 2001 From: Holger Hans Peter Freyther Date: Wed, 16 Jun 2010 12:02:13 +0800 Subject: bsc_init: Allow DTXu and enable DTXd on RSL Allow the MS to use uplink discontinous transmission by setting the right bit in the SystemInformation and set DTXd/DTXu on the RSL channel commands. This is configurable via dtx-used (0|1) on the network level.. --- openbsc/src/abis_rsl.c | 5 ++++- openbsc/src/bsc_init.c | 10 ++++++++-- openbsc/src/vty_interface.c | 14 +++++++++++++- 3 files changed, 25 insertions(+), 4 deletions(-) (limited to 'openbsc/src') diff --git a/openbsc/src/abis_rsl.c b/openbsc/src/abis_rsl.c index aa285e26b..eefdbc5a0 100644 --- a/openbsc/src/abis_rsl.c +++ b/openbsc/src/abis_rsl.c @@ -329,7 +329,10 @@ static int channel_mode_from_lchan(struct rsl_ie_chan_mode *cm, memset(cm, 0, sizeof(cm)); /* FIXME: what to do with data calls ? */ - cm->dtx_dtu = 0x00; + if (lchan->ts->trx->bts->network->dtx_enabled) + cm->dtx_dtu = 0x03; + else + cm->dtx_dtu = 0x00; /* set TCH Speech/Data */ cm->spd_ind = lchan->rsl_cmode; diff --git a/openbsc/src/bsc_init.c b/openbsc/src/bsc_init.c index 037845b11..757d64158 100644 --- a/openbsc/src/bsc_init.c +++ b/openbsc/src/bsc_init.c @@ -1056,8 +1056,14 @@ static int bootstrap_bts(struct gsm_bts *bts) } /* some defaults for our system information */ - bts->si_common.cell_options.radio_link_timeout = 2; /* 12 */ - bts->si_common.cell_options.dtx = 2; /* MS shall not use upplink DTX */ + bts->si_common.cell_options.radio_link_timeout = 7; /* 12 */ + + /* allow/disallow DTXu */ + if (bts->network->dtx_enabled) + bts->si_common.cell_options.dtx = 0; + else + bts->si_common.cell_options.dtx = 2; + bts->si_common.cell_options.pwrc = 0; /* PWRC not set */ bts->si_common.cell_sel_par.acs = 0; diff --git a/openbsc/src/vty_interface.c b/openbsc/src/vty_interface.c index 314277068..6486c0d21 100644 --- a/openbsc/src/vty_interface.c +++ b/openbsc/src/vty_interface.c @@ -1,4 +1,4 @@ -/* OpenBSC interface to quagga VTY */ +/* ipenBSC interface to quagga VTY */ /* (C) 2009-2010 by Harald Welte * All Rights Reserved * @@ -500,6 +500,7 @@ static int config_write_net(struct vty *vty) vty_out(vty, " timer t3117 %u%s", gsmnet->T3117, VTY_NEWLINE); vty_out(vty, " timer t3119 %u%s", gsmnet->T3119, VTY_NEWLINE); vty_out(vty, " timer t3141 %u%s", gsmnet->T3141, VTY_NEWLINE); + vty_out(vty, " use-dtx %u%s", gsmnet->dtx_enabled, VTY_NEWLINE); vty_out(vty, " ipacc rtp_payload %u%s", gsmnet->rtp_payload, VTY_NEWLINE); vty_out(vty, " rtp base %u%s", gsmnet->rtp_base_port, VTY_NEWLINE); @@ -1468,6 +1469,16 @@ DECLARE_TIMER(3117, "Currently not used.")
