Merging tw-e1abis-mgw into mainline Osmocom
by Mychaela Falconia 12 Oct '25

12 Oct '25

Dear Osmocom community, A little over a month ago I announced availability of this new MGW: https://osmocom.org/projects/retro-gsm/wiki/ThemWi_E1_Abis_MGW So far only two people responded to this news: Csaba has been testing this new MGW on his Nokia MetroSite (he and I are working toward adding AMR support), while Keith took only a passing notice - if I understood him correctly (please forgive me if I misunderstood!), it looks like Rhizomatica/TIC no longer operate GSM networks with Ericsson RBS gear, hence no more need for improved E1 MGW from their side. However, I am getting a sense that the larger Osmocom community may be disappointed regarding my choice to develop this improved E1 Abis MGW as a "rogue" project external to Osmocom, rather than in the form of patches to osmo-mgw. Therefore, I have given some thought to how it might be possible to merge this new E1 MGW into mainline Osmocom. Here are my current thoughts: 1) Integrating improved functionality of tw-e1abis-mgw into osmo-mgw in a fully unified manner, full coexistence of all existing osmo-mgw functionality plus all tw-e1abis-mgw functionality within a single program/process, running on one MGCP port and providing both rtpbridge and E1 endpoints, is beyond my ability, or at least beyond what I can do using only my own volunteer time. osmo-mgw code base is extremely complex, and as much as I dread to say it, insanely and needlessly so - it is a Gordian knot, and I tend to approach those the way Alexander did... 2) As an intermediate compromise between the too-difficult goal of point 1 above and the current status quo of tw-e1abis-mgw existing externally to Osmocom, how would Osmocom community feel about a hypothetical osmo-e1-mgw program? Suppose I were to produce patches that add osmo-e1-mgw as a new program to osmo-mgw git source tree, such that osmo-mgw and osmo-e1-mgw binaries would be built side by side in the same source tree - any interest? The actual code bases compiling into these two binaries would still be mostly separate, just the autotools infra of osmo-mgw git tree would be shared, but the new osmo-e1-mgw program would carry Osmocom branding, and it would live in a mainline Osmocom repository where people other than me can shape its future direction. Please note that I don't need this integration for myself: for our own use on our to-be-built network, we (A2GC) are quite happy running the hybrid software stack where some components are built from Osmocom source repositories while other components are built from ThemWi repos. Instead I am making this offer to Osmocom community for social reasons: I wish to continue as an active member of this community, if possible, and fork-like activities are certainly _not_ the way to go, socially. I am also making this integration offer to the community as food for thought, without any urgency. If the greater Osmocom community does wish to see tw-e1abis-mgw turned into something like osmo-e1-mgw, integrated into mainline Osmocom, it will probably be another few months before I can start submitting patches in this direction. The reason for the delay is that tw-e1abis-mgw is not quite finished at the present moment: two big missing features are AMR support and UL-to-DL transform (aka TFO transform) for EFR. I would like to fill these two functional gaps in the new MGW while staying in my own tw-e1abis-mgw source tree, before beginning the process of merging into Osmocom mainline - hence the time delay prognosis. If Osmocom community does wish to see the improved E1 MGW as part of mainline Osmocom code base, I would need an explicit "green light" go-ahead before I start preparing any patches. The patch process would need to proceed as follows: 1) I will need to prepare a patch for libosmocore, adding a header file with definitions from 3GPP TS 48.103 Table 5.4.2.2.1. Right now ThemWi software, including tw-e1abis-mgw, uses <themwi/common/aoip_rtp_pt.h> header file - but of course the latter won't be available in pure Osmocom environment without ThemWi dependencies. 2) There will need to be a whole bunch of patches to libosmo-abis.git (libosmotrau portion thereof), adding various functions which I currently collect in libtwtrau and which will be used by the upcoming AMR-capable version of tw-e1abis-mgw. 3) Only after 1 and 2 above are merged, then I'll able to produce a big patch for osmo-mgw.git, adding osmo-e1-mgw (or whatever other name the community comes up with) as a new program. In any case, in the immediate short term I am going to continue improving tw-e1abis-mgw where it lives currently, in ThemWi area of Osmocom Gitea. Once AMR support and UL-to-DL transform for EFR are there, I will make another post here. At that point if the greater community would like to see this work merged, I will need feedback in this ML thread. GSM/2G Forever, Mother Mychaela

Re: Merging tw-e1abis-mgw into mainline Osmocom
by Sipos Csaba 10 Oct '25

Hi Mychaela, My two cents on the subject is that any solution seems better than a fork. This is a small community, what we are doing is even more niche. Visibility is as important as the features themselves, therefor whatever the community thinks is appropriate to somehow integrate/merge these into existing Osmocom projects (MSC/MGW and libraries), seems like a better approach. In this sense probably option 2. seems an easy way out of this for now. I am also planning to add more Nokia BTSes to the supported list, namely Flexi EDGE, Multiradio and Multiradio 10. If anyone has access to a minimal viable setup (BTS+1 RF unit at least), or has equipment and can provide remote access, and/or want to donate it, please let me know. Of course older Nokia units (Talk family and even older units) are also welcome. Regards, Csaba

More efficient RTP transport for CSD
by Mychaela Falconia 25 Sep '25

25 Sep '25

Dear Osmocom community, Those of you who had occasion to work with CSD probably noticed that the standard RTP payload format prescribed for AoIP by 3GPP Rel8+ (64 kbit/s CLEARMODE) is extremely wasteful: 160 bytes of payload every 20 ms (compared to a maximum of 33 bytes every 20 ms for voice calls), and most of that 160-byte CLEARMODE payload is constant filler. The actual information content for CSD channels traveling across A interface (data bits plus all metadata preserved, strictly lossless conversion) fits into 16 bytes for CSD modes up to 4.8 kbit/s, 32 bytes for 9.6 kbit/s or 37 bytes for 14.4 kbit/s - much more compact than the 160-byte standard! Because my non-profit org in USA (American 2G Cooperative) will soon be operating a public GSM/2G network as a membership co-op, we have a legal and ethical obligation to provide all services strictly at cost. Radio resource usage is exactly the same between voice and data calls, while CPU load on tw-border-mgw machines in the CN will often be even less with CSD than with EFR or AMR speech transcoding - hence there is no legitimate reason for CSD calls to be more expensive than voice. Yet the bloated RTP format prescribed by 3GPP Rel8+ artificially increases the cost of IP transport within the network. My solution to the problem: yet another TW-TS, specifying a modified version of AoIP interface with compressed CSD. Here is the spec: https://www.freecalypso.org/specs/tw-ts-007-v010001.txt An updated version of TW-TS-003 (BSSMAP extension spec) spells out how the MSC requests the use of compressed CSD instead of standard TS 48.103 on AoIP by adding RTPext IE to ASSIGNMENT REQUEST or HANDOVER REQUEST, with the right bit set to request TW-TS-007 RTP format. In terms of implementation of this newly defined feature in Osmocom, my plan is as follows: * Within the past couple of years I extended osmo_trau2rtp() and osmo_rtp2trau() to support CSD on E1 BTS, using standard CLEARMODE format on RTP side. I plan to extend these functions to support TW-TS-007 as well. * Combination of mainline OsmoBSC plus tw-e1abis-mgw has fully working CSD with E1 BTS, already tested with Nokia InSite. If my idea for representing TW-TS-007 compressed CSD format in MGCP/SDP is acceptable (please see chapter 9 and Annex A in the spec linked above), I would like to extend OsmoBSC to be able to command tw-e1abis-mgw via MGCP/SDP to emit either standard CLEARMODE or TW-TS-007 per request from MSC. The above points are for E1 BTS. With IP-native OsmoBTS, we have two options: 1) We could add more logic to OsmoBTS to emit either standard CLEARMODE or TW-TS-007, just like we already do for TW-TS-001/002 carrying TRAU-UL metadata bits for FR/HR/EFR. 2) We could leave OsmoBTS completely unchanged, speaking only standard CLEARMODE format for CSD, and have OsmoBSC-associated OsmoMGW convert on the fly (we are dealing with strictly lossless conversion here, not bringing back extra metadata as with other TW-TS) if the MSC asked for TW-TS-007 compressed RTP format. Option 2 seems easier to implement, and I am leaning toward this option. Of course this option only makes sense when osmo-bsc, osmo-mgw and osmo-bts-trx run on the same SBC next to or inside SDR-based BTS, or when the link between the BSC and the BTS is a local Ethernet cable, while A interface travels across public Internet or other networks where bandwidth matters. What does the community think? For my own operation E1 BTS is a higher priority (I still plan on using surplus Ericsson RBS6k gear), hence there is plenty of time for Osmocom community to provide feedback on how y'all would like to see this mechanism working with IP-native OsmoBTS. In terms of upcoming Gerrit patches related to TW-TS-007, I plan to work on libosmo-abis next, implementing lossless conversion functions and extending osmo_trau2rtp() and osmo_rtp2trau() for efficient, native support of compressed CSD. GSM/2G Forever, Mother Mychaela P.S. If anyone has constructive criticism regarding chapter 9 or Annex A in the TW-TS-007 spec linked above (AoIP and SDP aspects), it is not too late to revise those parts.
