I’m sorry i don’t know what is early allocation, it do’esn’t ring any bell.
when a timeslot is defined as SDCCH dynamic, it means that when timeslots defined as TCH are not full, and there are SDCCH requests that can’t be carried by the “static” SDCH timeslots, the dynaic SDCCH timeslots will become a SDCCH/8 timeslot.
It will remain a SDCCH/8 TS as long as there are enough SDCCH requests to occupy the static SDCCHs + the dynamic SDCCHs.
If there are less SDCCH, the dynamic will wait a while before reconfiguring to TCH.
I think this description was given in another thread, few hours ago…
