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 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 Complexity: C1 - Support DUN networking over the USB transport. This might require extra AT commands to be implemented in order to comply with general USB DUN expectations as there is no standard for the same. Complexity: C4 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. Complexity: C4 Priority: Low Depends: HFP AG emulator - Integrate HFP AG emulator as a BlueZ service. Replace direct access to Bluetooth library by usage of the BlueZ service architecture. Complexity: C2 Priority: Medium Depends: HFP AG emulator - Add audio management to HFP AG emulator. 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. Complexity: C4 Priority: Medium Supplementary Services ====================== - Closed User Group (CUG) support. Priority: Low Complexity: C8 - Call Completion to Busy Subscriber (CCBS) support This feature is not discussed in 27.007, thus manufacturer specific commands are required. Priority: Low Complexity: C8 - User to User Signaling (UUS) support Priority: Low Complexity: C8 - 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. Priority: High Complexity: C1 Owner: Nicolas Bertrand Voicecall ========= - Dial strings. Include CLIR prefixes and 2nd stage dial strings in the DialString call property. Add dialstring accessor method to C API. Priority: Medium Complexity: C4 - Provide feedback of sent DTMF tones. Emit SendingTones signal if modem can provide approximate starting and stopping times for DTMF tones. Signal argument contains a string of DTMF tones to be sent, or empty string when all tones has been sent. Priority: Medium Complexity: C2 - Blacklisting. According to 3GPP TS 22.001 annex E, the TE must provide automatic calling repeat call attempt restrictions. There should be a method to manually reset blacklisting. Priority: Medium Complexity: C1 - DTMF Driver hints Currently multiple DTMF tones are sent to the driver in batches of up to 8 characters. For those drivers that can only accept a limited set of DTMF characters at a time (e.g. one), add a setting to the core that will change this batch size limit. Priority: Medium Complexity: C1 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. - CLOSE CHANNEL:requests the terminal to close the specified data channel. - RECEIVE DATA:requests the terminal to return to the UICC data received on the specified channel. - SEND DATA:requests the terminal to send on the specified channel data provided by the UICC. - GET CHANNEL STATUS: requests the terminal to return the current status of all available data channels. Priority: Medium Complexity: C4 Owner: Philippe Nunes - Support Setup Event List proactive command. To fully support the class 'e', the following events -Data Available event -Channel status event shall be monitored by oFono if part of the current event list. This list is supplied by the last SETUP EVENT LIST command. Priority: Medium Complexity: C2 Owner: Philippe Nunes Miscellaneous ============= - PolicyKit support. Add support for PolicyKit checking of all oFono D-Bus interfaces. Complexity: C4 Priority: Low - Add Location Service API for providing basic E911 support. This will be based on the 27.007 defined AT commands using XML for transport of positioning request and responses. Priority: Medium Complexity: C2 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 Complexity: C2 CDMA SMS ============== - Support CDMA SMS stack in PDU mode. This includes basic support of SMS Point-to-Point Message, SMS Broadcast Message and SMS Acknowledge Message as per 3GPP2 C.S0015-B version 2.0. Priority: High Complexity: C4 - Support sending Wireless Messaging Teleservice (WMT) Submit Message and receiving WMT Deliver Message as defined 3GPP2 C.S0015-B version 2.0. Priority: High Complexity: C4 - Support Delivery Acknowledgment. oFono allows requesting of CDMA SMS Delivery Acknowledgment via the MessageManager's UseDeliveryAcknowledgement property. If enabled, oFono's CDMA SMS stack will encode the Reply Option subparameter in the Submit message and process incoming SMS Delivery Acknowledgment Message. oFono will notify UI either via DBus or history plugin API. Priority: Medium Complexity: C2 - Support receiving Voice Mail Notification (VMN) Teleservice Deliver message. CDMA network uses VMN Teleservice to deliver the number of messages stored at the Voice Mail System to the CDMA mobile subscriber. 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. Priority: Medium Complexity: C4 - Support sending Wireless Application Protocol (WAP) Teleservice Submit Message and receiving WAP Deliver Messsage as defined 3GPP2 C.S0015-B version 2.0. Priority: Medium Complexity: C4 - 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. Priority: Medium Complexity: C2 CDMA CMAS ============== - Support Commercial Mobile Alert Service (CMAS) over CDMA systems. CMAS over CDMA system is defined in TIA-1149. The CMAS message is carried in the CHARi field of the User Data subparameter of CDMA SMS Broadcast message. Priority: Medium Complexity: C4 CDMA Network Acquisition ======================== - Support reporting of the pilot energy ratio (Ec/Io) measurement for the currently acquired CDMA network. Priority: Medium Complexity: C1 - Support of the signal to interference-plus-noise ratio (SINR) measurement for the currently acquired 1xEV-DO data network. Priority: Medium Complexity: C1 - Support reporting of the Enhanced Roaming Indicators (ERI) to indicate the 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, including the System Identifier (SID) and the Network Identifier (NID), It is the responsibility of the modem to broadcast the relevant identifiers for a currently acquired system, and these identifiers are provided by the network. This is described in 3GPP2 C.S0005-E v2.0. Priority: Medium Complexity: C2 - Support International Roaming, including support for reporting the Mobile Country Code (MCC) and the Mobile Network Code (MNC) for the currently acquired network. International Roaming is provided via enhancements to the PRL by encoding the MCC and the (two digit only) MNC in existing SID/NID fields, as described in the CDMA Development Group standards Document "IPRL Enhancements for International Roaming - CDG Doc #86". It is the responsibility of the modem to broadcast the values for the currently acquired system. Priority: Medium Complexity: C2 - Support reporting of the current registered operator name in long alphanumeric format. Based on the System Identifier (SID) broadcasted by the modem, the CDMA network name is retrieved from a look-up table (aka the 'mobile broadband provider info' database). Priority: Medium Complexity: C2 CDMA Connection Manager ======================= - Support Packet Data Service over CDMA (1xRTT and 1xEV-DO) systems. This includes Mobile Originated connection and disconnection features. Priority: Medium Complexity: C4
