hello
my name is thomas and i study communication engineering at tfh berlin. i
write my bachelor this semester. the task is to program a handover
funktion between 2 bs11, openbsc runs on a pc with e1 interface. but
there are major problems. i can't login with my 2 handys that i use for
that. nokia 3310c and 6650. the network is found, but the login fails,
with both handys. it worked only one time, with the 6650. i backuped the
hlr-file. i assume it's this file that makes problems. when i delete the
hlr, it is new created, and none of my handys can login. when i restore
this special hlr, the 6650 connect without problems, but only this one.
is there a tool to edit hlr.sqlite3, windows-based if possible?
where are the protocoll files stored, for error search, or must i make a
screenshot ?
Hi Thomas,
have you done C programming during your study? Do you start the bsc_hack
process yourself? How much knowledge do you have about GSM? How much can
your supervisor help you?
As this is supposed to be the work for your bachelor degree and the
issue is pretty basic, and there are examples of this on the webpage, I
think you should take the time to search for it.
If you have specific questions regarding the sourcecode, or how we
interpreted the GSM protocol, magic numbers in the code or such please
come back to us.
regards
holger
