<ul></ul><p>Aspects to consider:</p>
It is benificial if PDCH are in consecutive timeslots.
<ul>
<li>If dynamic timeslots are in use, it makes sense to trigger re-assignment to move them as far away from dedicated PDCH as possible.</li>
<li>If a dedicated TCH timeslot becomes available, it makes sense to re-assign away from a dyn TS towards a dedicated timeslot.</li>
</ul>
<p>An unused dynamic timeslot may count as both 1 free TCH/F and 2 free TCH/H. If one TCH/H becomes used, this implicitly also reduces the number of free TCH/F. The lchan picking algorithm must not get confused by that.</p>
<p>A dynamic timeslot being available as PDCH is benificial to GPRS service. So, if a neighboring cell is unloaded and has good rxlev, we may want to handover away from dynamic timeslots to make room for PDCH. rxlev vs PDCH tradeoff should be configurable.</p> OsmoBSC - Bug #3002: HO2: handover decision for dynamic timeslotshttps://projects.osmocom.org/issues/3002?journal_id=94982018-05-25T13:39:08Zneelsnhofmeyr@sysmocom.de
