Description
Use a pchan config that will switch over all available TS to voice.
Test Osmocom style dynamic timeslots:
network dyn_ts_allow_tch_f 0 bts 0 trx 0 timeslot 0 phys_chan_config CCCH+SDCCH4 timeslot 1 phys_chan_config SDCCH8 timeslot 2 phys_chan_config TCH/F_TCH/H_PDCH timeslot 3 phys_chan_config SDCCH8 timeslot 4 phys_chan_config SDCCH8 timeslot 5 phys_chan_config SDCCH8 timeslot 6 phys_chan_config SDCCH8 timeslot 7 phys_chan_config SDCCH8
A voice call will switch over to TCH/H and assign one of the two available TCH/H to each MS.
As soon as both legs of the voice call are released, the TS goes back to PDCH.
Test ip.access style dynamic timeslots:
timeslot 0 phys_chan_config CCCH+SDCCH4 timeslot 1 phys_chan_config SDCCH8 timeslot 2 phys_chan_config TCH/F_PDCH timeslot 3 phys_chan_config TCH/F_PDCH timeslot 4 phys_chan_config SDCCH8 timeslot 5 phys_chan_config SDCCH8 timeslot 6 phys_chan_config SDCCH8 timeslot 7 phys_chan_config SDCCH8
A voice call will assign both timeslots as TCH/F, one for each MS.
For both:
1. ensure GPRS use works
2. do a voice call between two MS, hang up
3. ensure GPRS use again works
4. do another voice call, to ensure repeated switching works
and
- test with CS encryption (see #3238 which shows that encryption could break PDTCH if it remains set after a TCH mode)
- while at it, why not also test without CS encryption.
