Cellular Network Infrastructure » OsmoGSMTester

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.
