About me

Thomas Seiler, MSc Telecom with a major in embedded systems.

My Interestes:

• Getting capacitive Sliderbar Sensors into the Neo GTA02/GTA03 (Cypress PSOC / Capsense)
• Makeing gsmd more robust
• Wrap platform functionality into a consistend DBUS based interface.
• Speeding up the boot process

Thoughts on gsmd

• do not reset modem on startup
• do instead query modem state
• have a struct that represents the modems state
• have a separad cli tool to init the modem via gsmd in a synchronnous manner, called from the rc-init scripts

Thoughts on possible DBUS wrapper for gsmd / asla / etc

Each independent Statemachine should be exported via its own DBUS object A signal should be broadcasted for each state change, so that the gui can react accordingly.

SIM Object

• Goal: Abstract away the fact that you need to access the SIM via gsmd, have a simple hook to show the corresponding dialog when needed.
• States: NO_SIM, NEED_PIN, NEED_PUK, NEED_PIN2, NEED_PUK2, OPEN, LOCKED
• Methodes: setPIN, setPUK, setPIN2, setPUK2, close, accessPhonebook, accessSMS, lowlevelQuery

GSM Network Object

• Goal: Abstract all Meta Information about the GSM Network, provide an interface to choose the network to connect to.
• States: NO_SIGNAL, EMERGENCY-ONLY, REGISTERED_HOME, REGISTERED_VISITOR
• Methodes: getNetworks, setPreferredNetwork, register, unregister, getDeviationStatus

IP Object

• States: UNCONNECTED, MODEM_BUSY, NO_IP, READY
• Connection Type: GPRS, CSD, WIFI, USBNET, OTHER
• Cost Indicator: LOW ..... MEDIUM ..... HIGH .... VERY_HIGH
• Methods: setProxy, getProxy, etc...
• Need to think this trough

VOICE-CALL Object

• States: ON-HOOK, DIALING, WAITING, TALKING, RINGING (incomming call)
• Methods: dial, cancel, accept, reject, getActiveCalls, putonhold, switch
• Problem: Single Statemachine is not ok when two calls are in progress at the

same time ?

VOICE-AUDIO Object

• States: STANDBY, OFFHOOK, MIC_MUTED
• Send signal on state change
• Methodes: provide methods to switch active audio during call, i.e. switchtoBTHeadset
• Need to think more about how to make this as generic as possible
• setup mixer to allow to record gsm conversation via /dev/dsp,
• and a switch for /dev/dsp playback into the gsm audio,
  • option1: the other party can hear it. (this is probably hard)
  • option2: only local party can hear it. (this is probably simple)

SIP Object

• Goal
• States: Unregistered, Registered

Presence Object

• Is this even needed ?
