<DIV><FONT face=Arial size=2><SPAN
class=821013408-12052010>hi,</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=821013408-12052010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=821013408-12052010>i like to give a
short update:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=821013408-12052010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=821013408-12052010>currently i am
testing the processes of selecting a cell and the network. the processes depend
on the coverage, the sim card (network, inserted or not) and the mode (manual or
automatic network selection). i hope i will finish this
week.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=821013408-12052010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=821013408-12052010>to configure mode
and sim card and other parameters in the future, i use the VTY, you already know
from the OpenBSC project. there you can get informations about the subscriber,
the mobile station and the received cells (system
informations).</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=821013408-12052010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=821013408-12052010>i will move all
hacked parameters (test sim) to VTY config file. manual network selection mode
requires reaction of the user, so it will also be added to the VTY. later the
VTY can also command the "call" part to dial, answer and hangup a
call.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=821013408-12052010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=821013408-12052010>my idea: later these
VTY command structure may be used for the phone's menu (up - down -
enter - escape), if compiled appropiate. also: if layer 3 is running on the
phone, the serial port could directly connect to the VTY, so the phone gets
a console interface for debugging and faster configuration.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=821013408-12052010>currently the
process (with sim card) ends while trying to do a location update. if the
given channel is not supported, the program exits. to prevent this, just
keep radio TX feature disable. the cell will be re-selected again and again
(hopefully if the process works correct).</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=821013408-12052010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=821013408-12052010>sometimes,
especially at the first run, the radio process stops. (no results for
measurements, no sync to selected frequency.) </SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=821013408-12052010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=821013408-12052010>also there is
something i am wondering: calibration especially for the burst
signal phase is measured and then stored on the eeprom by the manufacturer.
do we use it? or do we need to do our own calibration?</SPAN></FONT></DIV>
