"hello!" and "openbsc problem"

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 ? thanx thomas p.s.: answers in german prefered :-) -- Wer Rechtschreibfehler findet, darf sie behalten
