SMS: UCS-2 concatenation with UTF16 emoticons
by Keith 26 Apr '26

26 Apr '26

Hi all, I noticed that SMS with emoticons on the boundary of the concatenated segments are not displaying correctly on the destination handset. * - imagine the disaster when that kiss-blowing smiley face thing at the end of your SMS turns out as a diamond with a ? for the recpipient! OMG, the potential butterfly effect is too much to think about... :)) So... This is my analysis: We have 140 bytes for the message, less the 6 bytes for the user header data in the case of concatenated SMS , leaving 134 bytes. It's well know that this means 67 characters per segment for an SMS using UCS-2 encoding. But, it we fill the message with emoticons that are using 4 bytes per 'character', then we have space for 134/4 = 33 and a half. Ooops. Still, the destination handset should reassemble the message and stick the two "halves" of the emoticon together, right? - except I'm not observing this. To rule out us doing something wrong in osmo, I wonder might somebody else (who has an unlimited SMS package) from a commercial provider try sending some crafted SM from one emoji-enabled phone to another, something like this: 😱abcdefghijklmnopqrstuvwxyz123456789abcdefghijklmnopqrstuvwxyz123😱56789 That's likely going to get mangled by mailing list or your mua, so it is: [4 byte emoji]abcdefghijklmnopqrstuvwxyz123456789abcdefghijklmnopqrstuvwxyz123[4 byte emoji]56789 You could also try various messages filled with emojis. Of course, if you bring up your osmo network with SMPP-mirror you can watch the trace in wireshark, you'll see when the last emoji gets chopped in two. You could try the same message on osmo and your commerical network. If it's actually a problem of the phones, you should get [4 byte emoji]abcdefghijklmnopqrstuvwxyz123456789abcdefghijklmnopqrstuvwxyz123[two diamonds with ?]56789 Thanks! Keith.

Front and back sides of an MSC
by Mychaela Falconia 26 Apr '26

26 Apr '26

Hello Osmocom community, I have a question about terminology that is not really specific to Osmocom, but is specific to GSM/3G/etc cellular industry, or whatever is left of it. An MSC in a GSM or 3G or any other circuit-switched cellular network has two sides: one side facing the RAN (A interface in GSM, IuCS in 3G), the other side facing PSTN or ISDN or BICC or SIP-I or whatever the fixed telephone network may be. My question: is there a general industry-wide agreement as to which side should be called the front and which should be called the back? To me it seems intuitive to refer to the A/IuCS side of an MSC as the front and the PSTN/ISDN/BICC/SIP-I side of the same MSC as the back. However, I am just one person, and I have no idea whether or not my view is intuitive to others. And it would even worse if the opposite convention happens to be widely used... Hence I am asking this community, in the hope that someone with more industry experience would know how telco network engineers casually refer to RAN-facing and fixed-network-facing sides of an MSC. For a long time I had the idea of building ThemWi MSC as a modular system (multiple processes talking to each other via sockets) with a stripped-down OsmoMSC derivative as the "central" component, and with a radically different placement of MSC-MGW. However, as I started working on more detailed design, I realized a major flaw in my originally envisioned architecture: my original approach to MSC-MGW would break TFO for AMR, specifically the dialogue between TFO-aware BTS and the TRAU equivalent in the MGW. I am now spinning a new architecture in my head, one which tentatively includes two dissimilar MGWs in the MSC. If my front vs back terminology is valid, then the front MGW (talking to AoIP user plane) would perform speech transcoding but become a transparent pass-through for CSD (basically a software-only, IP-based equivalent of a hardware TCSM colocated at the MSC site), while the back MGW would be a transparent pass-through for speech calls, but turn into a complex IWF for CSD. This tentative architecture exactly matches the placement of speech transcoding and CSD IWF functions in traditional hardware MSCs of TDM-based, before-AoIP world. But I need to know if I should keep these front and back terms, or swap them the other way around. M~

Beyond Legacy Boards: Why Digital Trust is the New Priority for Thai Communities
by arafatmohd857＠gmail.com 20 Apr '26

20 Apr '26

The digital landscape for social networking in Thailand is undergoing a significant transformation as we move further into 2026. For a long time, users relied on high-traffic but largely unmoderated directories to find local lifestyle updates and social connections. However, the recurring theme in our community discussions lately has been the overwhelming presence of "ghost" profiles and automated marketing scripts. In districts like Sukhumvit and Ratchada, where the social scene moves fast, the frustration of engaging with a profile only to realize it's a bot has reached an all-time high. This has led many to prioritize platforms that offer more than just a list of names, but a guarantee of human presence. The conversation often shifts toward finding a reliable fan4you alternative that addresses these security gaps through rigorous identity vetting. Long-term residents are highlighting that the main drawback of older systems is the lack of a "Proof of Life" requirement, which essentially leaves the door open for digital deception. By switching to a directory that utilizes "Liveness Ceremonies" and real-time verification, the community is reclaiming its safety. These modern platforms ensure that every "Verified" badge is backed by a real person, allowing users to focus on authentic social discovery rather than constant skepticism. https://fiwfan.app/trongpok69-alternative
