Not getting emergency messages via GSM..?

@Talkless
Hi, you are probably searching for Cell Broadcast:
https://en.wikipedia.org/wiki/Cell_Broadcast

I don't know if it is supported by UT.

It is not currently.

Thanks @Capsia and @dobey !

@Talkless yes we need that feature, call for volonteers

Strange, because it seems I received a Cell Broadcast message few days ago about COVID19.
Are there different kind of implementation ?

I received the message after turning off the flight mode after a good night sleep

@AppLee Only one time ? I received 3 times the same message. The first the 16 23:08, the third the 17 07:09 from GOUV.FR.

@domubpkm
~~Mine was from a 5 digit number.~~ Mine too as a matter of fact
And yes only once.

Cell towers are supposed to acknowledge for the phone the message has been delivered to if I understand it right. So maybe you have a bad cell coverage or something else happened in your case.

[Edit] Oups don't trust my memory

Mine was from a 5 digit number.

That was an SMS then.

AppLee · 24 Mar 2020, 17:43

@dobey
Actually I just checked it also came from GOUV.FR like @domubpkm
I'll edit my answer and won't rely on my memory anymore

dobey · 24 Mar 2020, 17:52

@AppLee I don't know what that is, other than I can see it is obviously not a web site. However, cell broadcast is indeed not supported in UT at the moment. Any message you would have received must either be an SMS or MMS.

AppLee · 24 Mar 2020, 17:53

@dobey
Alright, thanks for the clarification.

Talkless · 24 Mar 2020, 19:22

I too did get message.. the next day, and I believe that was regular SMS. Probably worked as a fallback?

kugiigi · 25 Mar 2020, 09:44

Yes, I'm sure this isn't supported yet on UT.
I remember earlier this year we had an issue with a volcano and there was a time where everyone's phone in the office randomly rings loudly because of the emergency messages except me LOL

issue with a volcano

Damn, now that's quite some issue . Rad.

@Talkless 2020 has been really an eventful year so far and our country's theme has been face masks (ashfall and now virus). I guess emergency messages are important now more than ever Anyone up for the challenge? I wonder if it's quite trivial or a complicated thing to do. Does ofono already support it?

flohack · 26 Mar 2020, 07:29

@kugiigi See https://github.com/rilmodem/ofono/search?q=cell&type= - there is a lot of code and even tests inside, so I would assume its at least somehow working.

flohack · 26 Mar 2020, 07:30

Okay it seems the cell broadcast is not implemented for the rilmodem driver, so yes, there would be some work to be done for the rild interface.

dobey · 26 Mar 2020, 16:51

@Flohack They also need to be handled specially in the rest of the system. There's no UI to present them, etc… and should not appear in messaging-app.

flohack · 26 Mar 2020, 16:53

@dobey Yeah agree. Its basically a feature-implementation through the whole middleware stack. Fun to do if you have nothing else to do lol.

Yeah and how would you actually test it..?
