Hi,
- The only channels which benefit from the filler table are BCCH and FCCH. But then we have another issue. If a BTS dies, BCCH and FCCH
continues to be transmitted and phones think that the cell is still here. But it reality it's dead. This is quite not handy both for development and for production. Note, that the BTS may die for a variety of reasons and not only because there is some bug in it, and RF transmission must stop at this point.
Definitely, this even can be a demand from regulation authority, depending on license conditions. This behavior may affect emergency call handling, and the least thing I want to see is interfering with 112/911! Besides, as a ham radio operator I simply consider it good practice taking a transmitter off-air when something dies. Even an unmodulated carrier can be accepted in this case, but not transmitting a BCCH without any meaning.
