GPRS mobility (cell change) support
OsmocomBB Layer 3 (RR/MM/CC)
In the CS plane, hand-overs are controlled by the BSC/network while a dedicated channel is active.
In the PS plane, the MS by default still autonomously selects new cells even while in dedicated (TBF) mode.
We at least need some basic capability for cell reselection for the PS plane.
