Description

ETWS (Earthquake and Tsunami Warning System) doesn't only use SMSCB, but also contains parts that ensure notification of all MS as quickly as possible. Specifically, this means

  • there's a PACKET APPLICATION INFO message sent over PACCH to all MS with TBF established

This ticket is about implementing the required features in the PCU.

We need to
  • receive the ETWS primary notification message from the BTS via the PCU interface
  • construct the PACKET APPLICATION INFO message from it
  • send it via PACCH to all MS in packet dedicated mode

One interesting question is that the specs don't appear to describe how often this is to be re-transmitted (if at all). I suppose as we're not operating RLC/MAC in reliable mode, messages might get lost and they have to be re-transmitted? For how long? Do we also need to send it to MS who are establishing TBF at some later point? For how long?
