Background
==========
- Priority scale: High, Medium and Low
- Complexity scale: C1, C2, C4 and C8. The complexity scale is exponential,
with complexity 1 being the lowest complexity. Complexity is a function
of both task 'complexity' and task 'scope'.
The general rule of thumb is that a complexity 1 task should take 1-2 weeks
for a person very familiar with oFono codebase. Higher complexity tasks
require more time and have higher uncertainty.
Higher complexity tasks should be refined into several lower complexity tasks
once the task is better understood.
SMS
===
- Add support for Enhanced SMS (EMS) from 3GPP 23.040. These SMS messages
support a richer set of formatting elements, including bold/italic and
font size selection. Embedding images and sounds into the SMS is also
supported. This task should add support for receiving such SMS messages.
Proposed solution is to convert such messages to HTML and embed image /
sound data as embedded MIME in the generated HTML stream. The EMS messages
will have to be detected (by the presence of particular tags in the SMS)
and signaled separately from simple SMS messages.
Priority: Low
Complexity: C8
- Asynchronously acknowledge SMS DELIVER messages sent by the SMS driver
to core using ofono_sms_deliver_notify(). This may require the struct
ofono_sms_driver to be extended with one more function pointer like:
void (*deliver_ack)(unsigned char *pdu, int len, cb_t cb, void *data)
because currently messages are automatically acknowledged by either the
modem (this is the case of some AT modems) or the driver right after
ofono_sms_deliver_notify() and a failure to deliver at an upper level is
ignored. The PDU can be an RP-ACK or RP-ERROR message with optional
TP-User-Content element, for example if returned from USIM Data Download.
Priority: Low
Complexity: C2
CBS
===
- Support UMTS format for CBS messages. This might be needed by some hardware
which does not convert UMTS-formatted cell broadcasts to GSM-formatted cell
broadcasts. The UMTS CBS format can be found in 3GPP 25.324 Section 11.1.
Priority: Low
Complexity: C2
SIM / SIM File system
=====================
- SIM Call History plugin. New UICCs support four new SIM elementary files
for storing call history information on the SIM: EFici, EFict, EFoci, EFoct.
A plugin should be developed for oFono that will write to these files.
Priority: Low
Complexity: C2
- Add support for SIM 'ready' notifications from the driver to the core. Most
modem manufacturers initialize the SIM (e.g. cache SIM file system, STK
initialization, etc) internally before allowing the telephony stack to
access these portions. When the PIN is locked, this can lead to oFono being
too fast for the modem and asking it for things before the firmware is ready.
The proposal is to introduce a new sim function:
void ofono_sim_ready_notify(struct ofono_sim *sim);
When oFono determines the SIM PIN is READY, it checks whether
ofono_sim_ready_notify has been called. If it hasn't, then it stalls the
initialization procedure (and calling post_sim) until
ofono_sim_ready_notify is called.
Priority: High
Complexity: C2
- Support SIM authentication: SIM and AKA suites.
Priority: Medium
Complexity: C4
- Support SIM authentication: GBA_U suite.
Priority: Low
Complexity: C4
- ISIM support
ISIM is the SIM application for IP Multimedia Subsystem, specified in
3GPP TS 31.103. The UICCs can support multiple ISIMs for different IMS
identities.
Priority: Low
Complexity: C4
Bluetooth HFP
=============
- Support HFP-specific AT commands for the HF role, providing an appropriate
D-Bus API when needed. Some examples are AT+BIA, AT+BINP, AT+BLDN, AT+BVRA,
AT+BRSF, etc.
Priority: Medium
Complexity: C2
Modem Emulator
==============
- Support CE4A extensions to HFP AG emulator. CE4A defines additional
AT command extensions to the Bluetooth HFP AG standard. Refer to CE4A
white paper: "AT-commands for Automotive Premium Phone Integration".
Plugins can register additional command handlers appropriately to handle
such commands.
Complexity: C4
Priority: Low
Depends: HFP AG emulator
- Support HSP AG. Similar to HFP AG emulator but implements the much reduced
Bluetooth HSP AG profile.

Priority: Low
- Support Bluetooth SPP profile.
Complexity: C4
Priority: Medium
- Support new HFP 1.6 AG commands allowing to publish, select and connect audio
codecs (AT+BAC, AT+BCS, +BCS, AT+BCC). This will need to interact with audio
framework.

Integrate HFP AG emulator to BlueZ and Pulse Audio.
Add audio related AT commands support: remote audio volume control and in-band
ring tone management.
Complexity: C4
Priority: Medium
Depends: HFP AG emulator as BlueZ service
PPP
===
- IPv6 CP support. To support IPv6 based GPRS contexts via PPP, GAtPPP
needs to be updated to support IPv6CP from RFC 2472.
Priority: Low
Complexity: C4
Location Services
=================
- Neighbor Cell Info. Add dedicated atom, D-Bus API and atom driver(s) for
Neighbor Cell information.
This feature is not discussed in 27.007, thus manufacturer specific commands
are required.

Supplementary Services
======================
- Closed User Group (CUG) support.
Priority: Low
Complexity: C8
- Call Completion to Busy Subscriber (CCBS) support

- Multiple Subscriber Profile (MSP) support
Priority: Low
Complexity: C2
- CPHS Support. This includes ALS and CPHS specific elementary files.
Priority: Low
Complexity: C8
- Call forwarding state handling change
At the moment call forwarding states are not always correct. Any active
conditional call forwarding should become quiescent while unconditional call
forwarding is activate. If call forwarding unconditional is subsequently
deactivated, all the quiescent forwardings should become operative again.
I.e. No conditional call forwarding string should be returned while
unconditional call forwarding is active even if they exist.
If there is an successful attempt to activate/deactivate conditional call
forwarding while unconditional call forwarding is active the conditional cache
flag should cleared.

Sim Toolkit
===========
- Support of the BIP (Bearer Independent Protocol) proactive commands.
The specification defines several bearer types. For now, only the packet data
service bearer is considered.
- OPEN CHANNEL: requests the terminal to open a data channel with
parameters indicated in the command. A user confirmation may be
requested by the SimToolkitAgent.

This list is supplied by the last SETUP EVENT LIST command.
Priority: Medium
Complexity: C2
Owner: Philippe Nunes <philippe.nunes@linux.intel.com>
Miscellaneous
=============
- Bluetooth SAP Client support. The Telit UC864-G devices support Bluetooth
SAP client mode. This requires the use of a modem side-channel to read the
APDU & CPDU data and send it to the remote phone device over Bluetooth RFCOMM
channel.
Complexity: C4
Priority: Low

CDMA Voicecall
==============
- Add support for Mobile Originated and Mobile Terminated Voice Call over
a CDMA network. This includes management of call state and providing
appropriate values for the LineIdentification in each case.
Priority: High
Complexity: C2
- Add support for Three-Way Calling over a CDMA network. Three-Way Calling
provides the subscriber with the capability to add a third party to an
established two-party call, so that all three parties may communicate in a
three-way call.
In CDMA mode, the originating subscriber of a current conversation can
request for a third party to be added to a conversation by sending a Flash
With Information Message (FWIM) with dialed digits to the network. Upon
setting up a two-way conversation with the added party, the originating
subscriber can request to establish a three-way conversation by sending
another Flash With Information Message. Upon receiving the second Flash With
Information Message, the MSC reconnects the original party to the
conversation thus completing the setup of a three-way conversation.
CDMA Three-Way Calling is described by Figure B-5 in 3GPP2 C.S0005-E Version
2.0.
Priority: High
Complexity: C2
- Add support for Call Waiting over a CDMA network. Call Waiting (CW) provides
notification of an incoming call to an originating subscriber, while the
subscriber's call is in the 2-way state. Subsequently, the originating
subscriber can either answer or ignore the incoming call. If the originating
subscriber answers the second call, it may alternate between the two calls.
In CDMA mode, the originating subscriber of a current conversation will
receive either a Flash With Information Message or an Alert With Information
Message from the network if there is an additional mobile terminated voice
call incoming. The originating subscriber can change conversation parties by
sending a Flash With Information Message to the network and the MSC will
toggle the speech path between the two conversations.
CDMA Call Waiting is described by Figure B-6 in 3GPP2 C.S0005-E Version
2.0.
Priority: High
Complexity: C2
- Support sending DTMF tones over CDMA network.
Priority: High
Complexity: C2
- Support optional network-based Plus Code Dialing for international calls over
a CDMA network. An input key, e.g. the "+" key, or a functional equivalent
can be used to replace the international access prefix when dialing. When
received, transmitted or stored, an international indicator can be included
with the address digits although it is the responsibility of the network to
ignore the international indicator when attached to a national number. This
is described in Section 2.7.1.3.2.4 of 3GPP2 C.S0005-E v2.0 and Section 1.2
of 3GPP2 N.S0027 v1.0.
Priority: High

Priority: High
Complexity: C4
- Support sending Wireless Enhanced Messaging Teleservice (WEMT) Submit
Message and receiving WEMT Deliver Messsage as defined 3GPP2 C.S0015-B
version 2.0.
WMT does not support message fragmentation thus can not be used to for
long message. WEMT is devised to support long message and Enhanced
Messaging Service (EMS). The WEMT SMS message's CHARi field of the
subparameter User Data encapsulate GSM-SMS TP-User Data as defined in
Section 9.2.3.24 of 3GPP TS 23.040.

- Support Call-Back Number. The Call-Back Number subparameter indicates
the number to be dialed in reply to a received SMS message.
In transmit direction, oFono allows setting of Call-Back Number. If the
Call Back Number property is set, CDMA SMS stack will encode Call-Back
Number subparameter in the Submit Message.
In receiving direction, oFono will process the Call-Back Number
subparameter in the incoming Deliver Message and notify UI of the
Call-Back Number together with the newly received text message.
Priority: Medium
Complexity: C2
- Support immediately displayed message. oFono CDMA SMS stack will
process the optional Message Display Mode subparameter in the incoming
SMS message. If Message Display Mode subparameter indicates the
message display mode is Immediate Display, oFono will send
ImmediateMessage signal, otherwise oFono will send IncomingMessage
signal.

current roaming condition of the CDMA mobile device. Each indicator maps to
a unique display number within the Standard and Non-Standard service ranges,
as described in Section 8 of 3GPP2 C.R1001-C v1.0.
These numbers are stored on the device in the (Enhanced) Preferred Roaming
List (PRL) and it is the responsibility of the modem to broadcast the
relevant indicator for a currently acquired system. Further details of the
system acquisition process are described in 3GPP2 C.S0016-B v1.0.
Priority: Medium
Complexity: C2
- Support reporting of identifiers of the currently acquired CDMA network,
