Well I guess you're right. I modified the source as suggested and tried it out. But there was no difference.

The reason I want to boost up its transmitpower, is because I wanted to test the handover. If our nanoBTS acts like a commercial provider I just see one MS trying to register to our nanoBTS. This is because it's just a meter away from our bts, while my mobile (an HTC Artemis) doesn't register to our bts with a distance of less than 10 m.
Even when I switch off and on, while I'm just a meter away of our bts, my mobile somehow keeps registering to the real provider (I tested by simply calling someone).

Another interesting thing is, if I simulate a total different provider, which doesn't exist here, I can easely find our bts, with manual search. Also the MS seems to have its own database of all the country codes, networkcodes and its belonging providernames. I thought the BSC sends these information to the MS and the MS checks it with SIM data. (But that;s off-topic).

Greetings.

go ahead and try, but I would bet on just about anything that it does not work.
Those are vendor-specific proprietary extensions of 12.21.  Values defined by
Siemens have no significance whatsoever for ip.access
