Not getting emergency messages via GSM..?

[Talkless]

Hi,

Here in Lithuania, sometimes mobile users receive emergency messages about, for example, upcoming strong winds, or in this case, about quarantine due to COVID19... Some "scary", distinct notification sound is emitted, I believe similar on iOS and Android.

Today, number of relatives received this kind of message.. bot nothing for
me..?

I wonder, is this something that has to be implemented specifically..? I don't know how that messaging system works. It does not look like SMS....

Any ideas?

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.

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.

That was an SMS then.

@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]

@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.

@dobey
Alright, thanks for the clarification.

[Talkless]

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

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]

@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]

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]

@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]

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