Hi all, I wanted to bring up the discussion about the delay tolerant (or large time transmissions) of data using SCHC. During the December meeting I gave a presentation providing the problem statement and a possible solution using SCHC fragmentation and reliability mechanisms (Delay tolerant over SCHC <https://datatracker.ietf.org/meeting/interim-2021-lpwan-13/materials/slides-interim-2021-lpwan-13-sessa-delay-tolerent-over-schc-00> (slides-interim-2021-lpwan-13-sessa-delay-tolerant-over-schc)<https://datatracker.ietf.org/doc/slides-interim-2021-lpwan-13-sessa-delay-tolerent-over-schc/>)/>). The main idea is to treat an transmittable object as a big IP packet and enable possibilities for very long time outs and multiple profiles configured for SCHC usage for both the downloads and uploads of large objects. One of the issues was the comment that the current charter does not include a mandate to work on this area explicitly. So the first question is if we need to update the charter to work on the topic. Secondly, the solution was mainly targeting a problem observed in the Cellular IoT but it was commented in the session that there could be similar needs for a solution targeting other LPWAN technologies and in that case a draft covering a general solution seems to be desirable. Is this really the case ? . How should we proceed ?, is it the charter discussion needed first ? or should we start with a draft ? Cheers Edgar R.
