[RFC] [CHANGE 1/2] Addidng initial documentation for basic assisted gps
by Benis, Robertino
Hi all,
This is first attempt to send out RFC for a-gps dbus documentation. It fill be followed by RFC for Infineon modem API implementation.
Thank you for your comments in advance. :-)
Thanks,

+Interface org.ofono.AgpsManager
+Object path [variable prefix]/{modem0,modem1,...}
+
+Methods dict GetProperties()
+
+ Returns properties for the modem object. See

+
+ Possible Errors: [service].Error.InvalidArguments
+
+ void SetProperty(string name, variant value)
+
+ Changes the value of the specified property. Only

+ void SendLCSFrame(string frametype, string framedata)
+
+ Send a LCS position protocol frame to the Mobile
+ Network. The LCS frame typically represents a
+ Position Response.
+
+ Valid frametypes are:
+ rrlp_measure_position_response
+ rrc_measurement_report
+

[PATCH 0/1] Patch Description
by Yang Gu
Sometimes we need to know the version of phonesim via a command. This patch is to add this support.
By the way, oFono introduces a file named version.h.in for the macro OFONO_VERSION. Can we use VERSION directly so that this file can be removed?
Yang Gu (1):
Add option to support version

[PATCH 2/2] atmodem: Add use of pin event *EPEV after sending PUK.

File Structure for persisting history in a disk file (Comments please)
by rajyalakshmi bommaraju
Hello,
I want to use the following file structure for persisting history in a
disk file. Can you please send me your feedback about it.
Thanks
Raji Bommaraju
_File structure for History
Persistance_
History information will be stored in a disk file. The file will have a
File Header consisting of "Bytes Stored" and "Head" for writing the next
record.Each record stored will have record header and record data,
record header has "record type" and "size of the record" (For Text
messages the records will have variable length message data resulting in
variable length records) hence this record structure is used.
*File Format:*
|File Header| Data |
File Header (8 bytes):
|Bytes stored | Head|
0 4 8
*Data:*
|Record|Record|.....etc
*Record:*
|Record Header|Actual data|
*Record Header:*
Record Type: 1byte (voice call history - 0, text history- 1)
Size : Integer
Actual data: Will be voice call or text message information

Emergency Calls
by Andras Domokos
Hi,
This is a proposal for handling emergency calls in ofono:
Detect when an emergency call is requested/ended and notify the interested,
subscribed parties, so that steps can be taken to ensure that the emergency
call can be established and maintained.
The "EmergencyMode" boolean property added to the VoicecallManager D-Bus
interface will reflect the emergency call situation.
There is an emergency watchlist in ofono_voicecall, where the watchers of
the interested parties are stored. When there is a change with regards to
emergency calls (call starts/ends), the watchers in the list are notified.
One interested watcher is the modem, it has to change the modem state from
offline to online for the duration of an emergency call.
The modem has a modem state watchlist, so that interested parties can
learn about the modem state changes. For emergency calls, voicecall manager
needs to know when the modem reached the online state, if a modem state change
to online was necessary.
The important details are in the patches.
Cheers,
Andras
