after location update fails. "DB: Failed to find the Subscriber...", get an "ERROR INDICATION" with cause 1. it seems that the mobile just stops sending on the channel. the channel ressource hold by location update process is not freed. the last messages show that.

i will look on this the next days and report if i found something. if you have any idea, please tell me. the way to test any change/fix is quite complicated. the bug only occurrs when many phones are available and when they move from a different network to my network (built in a car, moving arround.)

Just a wild guess: Could it be a reception problem ? If you have set the BS-11 to a high power level, many phones will see it. Currently the BS-11 advises the phones to use a very low power level when activating a channel. So the BS-11 might receive the phone with a low signal strength and the receiption is just too bad (although the phones will receive the BS-11 quite well). The measurement reports should indicate if this is the problem.

Out of interest, do you also have a PC with an E1 card in the car or do you use a laptop with an USB (or PCMIA) to E1 interface ?

Best regards, Dieter
