[M] Change in libosmo-abis[master]: osmo_rtp2trau() for FR & EFR: correctly handle the no-data case

by falconia

Attention is currently required from: neels, laforge. falconia has posted comments on this change. ( https://gerrit.osmocom.org/c/libosmo-abis/+/32078 ) Change subject: osmo_rtp2trau() for FR & EFR: correctly handle the no-data case ...................................................................... Patch Set 1: (2 comments) File src/trau/trau_rtp_conv.c: https://gerrit.osmocom.org/c/libosmo-abis/+/32078/comment/1e7ed5a4_a883df1a PS1, Line 282: } else if (data_len == 0) { : /* C1 .. C5: idle speech */ : tf->c_bits[0] = 0; : tf->c_bits[1] = 1; : tf->c_bits[2] = 1; : tf->c_bits[3] = 1; : tf->c_bits[4] = 0; Please read the rules of TS 48.060, particularly sections 6.5.2 and 6.5.3. Here is a bullet-point summary of these rules: * In the case of DL, for both FR and EFR, there is no choice: the TRAU must send an idle speech frame, which is distinguished from a regular speech frame by a unique C1..C5 pattern. * In the case of UL for EFR, the CCU must send a regular EFR speech frame (not idle speech frame) with BFI=1 - once again, no choice given. * In the case of UL for FR, the CCU has the option of sending either a regular speech frame with BFI=1 or an idle speech frame. Thus there is only one case where we as implementors get a choice: the case of FR UL. My patch implements the option of sending BFI=1, consistently with EFR when such behaviour is required. So let's decide on this issue first, before arguing over code structure: should we send a speech frame with BFI=1 or an idle speech frame in this case? Also @laforge wrote: > Basically above where the "FIXME: Generate SID frames?" comment is (which is no longer a FIXME then. This FIXME is fixed, and that comment removed, in the second patch of the series. https://gerrit.osmocom.org/c/libosmo-abis/+/32078/comment/b866177b_87816889 PS1, Line 441: if (data_len == 0 && tf->dir == OSMO_TRAU_DIR_DL) { > (wondering as above: why only for DL?) In the present case (EFR codec) the answer to the "why" question is straightforward: because TS 48.060 section 6.5.3 says so. -- To view, visit https://gerrit.osmocom.org/c/libosmo-abis/+/32078 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmo-abis Gerrit-Branch: master Gerrit-Change-Id: I7f21e2210bba9ef87f1af515a001a0cfc1c0a1d8 Gerrit-Change-Number: 32078 Gerrit-PatchSet: 1 Gerrit-Owner: falconia <falcon(a)freecalypso.org> Gerrit-Reviewer: Jenkins Builder Gerrit-CC: laforge <laforge(a)osmocom.org> Gerrit-CC: neels <nhofmeyr(a)sysmocom.de> Gerrit-Attention: neels <nhofmeyr(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Comment-Date: Mon, 27 Mar 2023 16:35:48 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: neels <nhofmeyr(a)sysmocom.de> Comment-In-Reply-To: laforge <laforge(a)osmocom.org> Gerrit-MessageType: comment

[M] Change in osmo-mgw[master]: mgcp_codec: refactor payload type converstion

by dexter

Attention is currently required from: dexter. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-mgw/+/32083 to look at the new patch set (#2). Change subject: mgcp_codec: refactor payload type converstion ...................................................................... mgcp_codec: refactor payload type converstion in mgcp_codec.c we have a function mgcp_codec_pt_translate that is used to find the equivalent payload type number on an opposite connection. This is quite specific and the resulting payload type number may still belong to a codec that might require some form of conversion. Lets refactor this so that the function just finds a convertible codec for a given connection. This also opens up other usecases. The payload type conversion like we did it before can then be done with a few lines in mgcp_network.c Related: OS#5461 Change-Id: I085260a2ca8cfecdb58656b7a046c536189e238d --- M include/osmocom/mgcp/mgcp_codec.h M src/libosmo-mgcp/mgcp_codec.c M src/libosmo-mgcp/mgcp_network.c M tests/mgcp/mgcp_test.c M tests/mgcp/mgcp_test.ok 5 files changed, 113 insertions(+), 65 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-mgw refs/changes/83/32083/2 -- To view, visit https://gerrit.osmocom.org/c/osmo-mgw/+/32083 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-mgw Gerrit-Branch: master Gerrit-Change-Id: I085260a2ca8cfecdb58656b7a046c536189e238d Gerrit-Change-Number: 32083 Gerrit-PatchSet: 2 Gerrit-Owner: dexter <pmaier(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Attention: dexter <pmaier(a)sysmocom.de> Gerrit-MessageType: newpatchset
