Description

We now have these dynamic pchan types:

  • TCH/F_PDCH (PDCH ACT style)
  • TCH/F_TCH/H_PDCH (CHAN ACT style)

It would be fairly trivial to add a dedicated TCH/H_PDCH type,
i.e. a TCH/F_TCH/H_PDCH (CHAN ACT style) that has TCH/F disabled.

Downsides: it adds a bit of code bloat (more switch cases...).

Benefits: Having this pchan type prevents phones from hogging a whole
TCH/F, theoretically doubling the capacity.

History

#1 Updated by neels almost 2 years ago

A different way to allow dyn TS without TCH/F is in https://gerrit.osmocom.org/603
if one adds a VTY command.

Of course it would be a far nicer user experience to have an actual TCH/H_PDCH pchan type.

#2 Updated by neels over 1 year ago

to be able to add a VTY command, https://gerrit.osmocom.org/1140 would be helpful.
So far, in the 603 patch we set dyn_ts_allow_tch_f after reading the config.
#1140 would allow setting the default to false in osmo-nitb only, and reading the config later on.

#3 Updated by neels over 1 year ago

gerrit patch 1140 is now merged to master, so we could now add a VTY config for
osmo-nitb to allow/disallow TCH/F on dynamic TCH/F_TCH/H_PDCH timeslots.
(My attention is with the VLR though.)
