860844 - [b2g-ril] Allow emergency calls to [000, 08, 110, 999, 118, 119] numbers without ICC card

Status: RESOLVED WORKSFORME

(Firefox OS Graveyard :: RIL, defect)

Description

[David Palomino [:dpalomino]]

Issue reported during certification in Spain with Ikura. 

Buildid "20130321070205", device: ikura
gecko commit: b5183c99228bdc5be33340e359efd1b4f0859e92 
gaia commit: 577d13088ebdbd353d13910d3317e713a140415b

The device (without a SIM card) successfully tries to perform emergency calls to 112 or 911. 

However, it is not allowed to do it with following emergency numbers: (000 / 08 / 110 / 999 / 118 / 119)

Thanks!
David

IMHO this is not a bug. Let me explain myself. If the device has a SIM card inserted the RIL stores the list of valid emergency numbers (ril.ecclist) for the country corresponding to the MCC code in the SIM card. If there is no SIM in the device there is no information about the country where the device boots and the list of valid emergency numbers stores a default set of values ([112, 911] the ones you mentioned). If you think about how the approach is that makes sense IMHO.

Oops, that's not true. I meant 'for the country corresponding to the MCC code which identifies the network that the device is connected to'.

It seems that the issue is because the device (without ICC card) must allow dial any of the emergency numbers in the list [000, 08, 110, 999, 118, 119, 112, 911]. Right now the default list of valid emergency number is [112, 911].

Vicamo, Anshul in order to allow the user to dial any number in the list you can see in the title of this bug we could do what I do in this patch but I cannot work since the rild daemon and libril* library binaries (it seems that) don't allow to dial any number that is not in the [ro.]ril.ecclist list. The thing is that we are limited to dial only to any of the number in the list and thus we cannot fix this issue with this patch and fix it from gecko. Anshul, how could we be able to fix this issue? Thanks!

Antonio, let me try to get this information for you.

Since that's etched in an open standard, let's do it :)

Yeah, I agree. Let's wait Anshul's information because the RIL binaries underneath are blocking the calls if we dial a number that's not in the [ro.]ril.ecclist lists.

[Reuben Morais [:reuben]]

So if the user doesn't have an ICC card, the numbers in the bug title are the *only* ones that can be dialed? In Brazil, 112 and 911 will redirect to the correct one, 190, but are not advertized anywhere, and although I don't have any data to back me up, are unknown to the very large majority of Brazilians.

[Reuben Morais [:reuben]]

Telefônica's public list of emergency service numbers:
http://www.telefonica.net.br/sp/utilidadepublica/emergencia.htm

Matches the list advertized by Brazil's telco regulation agency:

This is not okay. According to same document, chapter 8 "Emergency Calls" `When a SIM/USIM containing stored emergency numbers is present, only those numbers are identified as emergency
numbers, i.e. default emergency numbers stored in the ME are ignored.`

Well, we will take care about ICC card present or absent. Thanks Vicamo.

Vicamo, what version of that spec did you read? Is the correct one version 3GPP TS 22.101 V12.4.0 (2013-03)? Thanks!

This is a WIP in which I've tried to follow 22.101 V12.4.0 (2013-03) specs. We are still blocked on the issue commented in comment #4.

I think I got a pretty old one. :(

libril that populates the ecc list.
If the sim card is present, then it will use values from the EF file.
If no sim card is present, then it will rely on hard-coded an NV items.
The libril will also block any emergency call that is not listed in ril.ecclist.

I did a few tests and found that with no sim card inserted, the ril.ecclist property already has all the numbers requested:
	[ril.ecclist]: [911,112,000,08,110,999,118,119]
I've also verified that the libril is letting these emergency numbers through and the call connects.


:jaeoo on what device are you seeing the ecclist being empty when no sim card is inserted?

Thanks for the information!

The devices is Ikura device (AU 019.083). I guess the same happened when the certification test were performed, the ecclist was empty.

I guess you don't need any detail about the build. If you need more info please let me know.

[José Antonio Olivera Ortega [:jaoo]]

Same happening today:

BuildID 20130425151113
Firmware: V1.01.00.01.019.085

[ril.ecclist]: []

Comment 18

[Firefox_Mozilla]

we will to check these emergency numbers.

Comment 19

[Beatriz Rodríguez [:brg]]

I want to hightlight this is a OEM specific issue because I am testing with a different handset( Buri device with AU 19.088) and the list is:
[ril.ecclist]: [911,112,000,08,110,999,118,119]

Comment 20

[Anshul]

Beatriz, we have concluded the same. Our customer engineering team is following up with the OEM.

[José Antonio Olivera Ortega [:jaoo]]

Resolve this bug as it seemed worked for everybody. If not feel free to reopen it or file a new follow up bug.
