Sure that this is a good idea? It will throw out all users at the edge of the coverage area, maybe cause even more load, when those show up again with their accumulated requests like call attempts, SMS, additional LU, and in fact I have never seen that commercial networks do something like that. Is there not some waiting queue defined in the standards, with some timers, commanding the location updaters to wait for some period of time? Has been a long time when I looked into this, but I mean to remember that even OpenBTS does it this way. Or am I totally wrong? >From my point of view slowly increasing TX power is OK for booting a new cell >into operation, but during normal operation?! > -- > Regards, > Alexander Chemeris. > CEO, Fairwaves LLC / ООО УмРадио > http://fairwaves.ru Ralph.
