1220948 - [IMS] Add |onlosingservicecoverage| in Telephony to indicate the warning of losing service coverage during voice call.

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: RIL, defect)

Description

[Bevis Tseng[:bevis][:btseng](Exited)]

This bug is to provide the generic notification of losing service coverage during voice call.
This event contains a |bearer| property to indicate which service coverage is getting lost.

enum TelephonyBearer{"cellular", "ims-over-wifi", "ims-over-cellular" }

interface TelephonyLoseCoverageEvent : Event
{
  readonly attribute TelephonyBearer bearer;
};

Any suggestion on the interface defined in comment 0 is welcome. :)

"cellular" means traditional CS network in GSM or CDMA.

To prevent the confusion about the supported bearers of this notification.
I'd like to reduce the enum of TelephonyBearer to {"ims-over-wifi"}, then we could add more types if supported in the future.

Bevis, I like the idea of the enum of TelephonyBearer which looks clear :)

A minor suggestion for the interface name: I am inclined to "TelephonyCoverageLosingEvent" to have the name closer to plain English (I hope... :P ).

Since we're talking about having the name be closer to plain English, maybe "TelephonyLosingCoverageEvent"?

Not really, but to see if you agree this approach in comment 0 and comment 2 as well.

Not necessary anymore of this new API.
