958733 - [cdma][supplementary services] GSM SS are being initiated when acquired on CDMA network

Status: VERIFIED FIXED

(Firefox OS Graveyard :: Gaia::Dialer, defect)

Description

[Michael Schwartz [:m4]]

Steps:

# Acquire on a CDMA network
# Dial a GSM SS eg. *#43#

Actual:
# Attempt to initiate a GSM supplementary service which cannot succeed on a CDMA network

Expected:
# Initiate a CDMA call to given dial string

Hsinyi, are we going to move the decision rule of supplementary service to Gaia?

No, instead, we are going to move the determination algorithm to gecko. That's what bug 889737 tries to do.

Right now, gaia/dialer checks if the dialing string ends with #. If so, dialer calls 'mobileConnection.sendMMI()' that causes some problem on CDMA networks as this bug reports. If we want to have a quick workaround for this bug on gaia instead of waiting for the full solution on bug 889737 landed, dialer should have a careful check on the network type as well.

Gabriele, is that something you could do?

Comment 4

[Ken Chang[:kenkai]]

Joe, this bug depends on bug 889737. However, Bug 889737 depends on bug 969218 and bug 969280. I wonder if you could find someone to take the bug 969280.

Yes, it should be a fairly simple job once the dependencies are fixed.

Thanks! So, could you be the owner for this bug? Then, we could know that once the dependencies are all fixed, we will have you to help this bug. Thank you.

hi Gabriele, do you mind taking the bug? if you will be working on this once the depending bug is fixed. thanks

[Hsin-Yi Tsai (she/her) [:hsinyi]]

As the work of Bug 889737 is huge, we don't think we are able to finish that by Feb. 28. I'd like to propose a gaia workaround for this issue.

My proposal:
In dialer/js/mmi.js, isMMI() considers two conditions:
1) return false if the network is CDMA.
2) return (number.charAt(number.length - 1) === '#') // The existing criterion

How do you think, Gabriele?

I'll let Gabriele comment on the pertinence.
But it looks simple/testable enough :)

Pretty simple as Etienne said, and definitely testable. Shall we go for this solution and then open a follow up for when mobileConnection.sendMMI() will be gone?

Sounds really good. +1!

Attachment: [PATCH] Never validate MMI codes in CDMA networks

Here's a patch that modifies MmiManager.isMMI() to never validate MMI codes when a CDMA network is detected; comes with unit-tests. The only thing I'm not sure about is if the type of network is right: I'm currently checking just for 'cdma' but there's apparently plenty of variations (wcdma, evdo, etc...). If this test needs to behave similarly for them I'd need a list to be sure not to miss any.

Here's my suggestion:

var cdmaTypes = ['evdo0', 'evdoa', 'evdob', '1xrtt', 'is95a', 'is95b'];
var conn = window.navigator.mozMobileConnection ||
           window.navigator.mozMobileConnections &&

I think mozMobileConnection is history. We shouldn't use it in new code.

Hi guys,

Sorry that please HOLD the check-in for a while.
There's a very tricky case  -- *#06#. *#06# is a very special case and the string is checked in keypad.js. Right now, we call sendMMI(*#06#) to get IMEI. Actually *#06# (IMEI) is only useful and meaningful in gsm/world phones. Wasabi is a world phone so that we can get IMEI via *#06# even the network camped on is cdma. This patch checks the camped network type to enforce dial() for cdma networks. This is nothing wrong I'd say. However, as *#06# requires special handling and to not break the behaviour we have on wasabi before this patch, I'd suggest we do one more thing: we simply use sendMMI() for *#06#.

Or a more concrete solution:
We do special handle for *#06# if mobileconnecitons[0].supportedNetwokTypes contain 'gsm' or 'wcdma' or 'lte'. But I guess this work might huge?!

Comment 28

[Gabriele Svelto [:gsvelto]]

OK, so let's do two things here: first I'll get rid of the use of mozMobileConnection, then I'll whitelist the *#06# code as Hsin-Yi has suggested on 'gsm', 'wcdma', and 'lte' phones. IMHO this is no big deal as this is really a workaround. Once the real fix will be in place this code will go away anyway.

Agree this is not a big deal. Either way is okay. :)

Attachment: [PATCH 1/2 v3] Never validate MMI codes in CDMA networks

Updated patch with the IMEI requested code appropriately whitelisted as per Hsin-Yi's description in comment 27; an additional unit-test has been added for this. I have not removed the use of |window.navigator.mozMobileConnection| as it would break the tests and as discussed we should move the fixes for the tests in a follow-up bug we'll use to clean up all uses of that obsolete field.

Requesting review again as the changes are significant.

Removing mozMobileConnection requires me to change the tests and this touches other parts of the code so I'd rather not do it here. As we discussed during this morning stand-up meeting I'll open follow-ups to remove all uses of mozMobileConnection and update all the affected unit-tests.

Verified on CDMA build. It will dial GSM USSD code as a voice call, not send it as a message.
