<ul></ul><p>I'm not sure if this is an issue anymore, it needs to be investigated (and possibly get a test case?). With the current code base we should always do late assignment, even if the MS requests a TCH in RACH...</p> OsmoBTS - Bug #2790: dynamic timeslots: failure when all TS are used as PDCH and the phone requests a TCHhttps://osmocom.org/issues/2790?journal_id=99402018-06-18T07:17:01Zdexter

<p>Ok, so, quick recap to think about it:</p>
<p>- when MS requests a channel, even if it is TCH, OsmoBSC always assigns an SDCCH first as long as it is available.<br />- when no SDCCH are left, the upcoming refactored OsmoBSC will pick a TCH instead. The new timeslot and lchan FSMs will make sure that the dyn TS is switched from PDCH first, if required.</p>
<p>So, yeah, this should actually not be a problem anymore.</p>
