Hello All
I have a plan to add CDMA/EVDO support into ofono. The
attachement is TODO patch I get ready to submit into ofono.
In this patch file is a simple description about what CDMA/EVDO
features will be covered. I'd love to have your thoughts about this.
Best Regards

Hi Penghuo,
I am not fully against submitting patches as attachments, but if you do
expect reviews, then we do prefer inline patches. I would advise to
start using git send-email for patch submission.

Actually this is not a TODO item. That is a modem plugin specific
detail. If your modem (CDMA or not) doesn't supports such features,
then
don't enable the atoms for it.
So I say that this already supported ;)
I do agree, besides, some atoms such as call-barring, call-setting ...
Need do a little change, we need to disable the USSD watch and SSN watch etc.

These features in CDMA are very different from that in GSM. Call forwarding and
call waiting
are achieved by dial a specified number(feature code). In CDMA system, the modem
will always auto register network, but in GSM system, there are different register
modes,
and can scan neighbor networks.
So we would like implement them in separate files such as cdma_call-forwarding.c ...
But not base on current implementation.

Yes, we do agree. We will do it.
Generally, before do any change, we will sent out the proposed solution,
and collect the suggestion first.

Just to nitpick, but if you don't create the SSN/USSD atoms, then the
atom watch will never fire.
Can you include descriptions of what needs to change in these atoms in
your TODO list as well?

I'm not against this in general, but please start sharing with us more
details. E.g. why these are different, why the current atom cannot be
extended, etc. In some respect you will have to educate us about CDMA
first.
It would also be very helpful if you posted a table with CDMA feature
break down and the relevant CDMA specs. E.g. like SMS in 3GPP is
covered in 23.040, CBS in 23.041, etc. This way we can go straight to
the spec to help us understand why a particular solution was proposed.
I believe that would shorten our ramp up time considerably. I've
updated doc/standards.txt to give you an idea of what I'd like to see.

I'd also like you to greatly expand your TODO item descriptions. The
current level of detail is not enough. Think of TODO as a sort of
high-level design document, but targeted at developers. The more detail
you add here, the better.
