crap or FRAND?
IANAL but...
Isn't the concept of calculating the best base station to use based on signal strength and error rate fairly obvious to anyone with even a little knowledge of data networking /electronics/radio broadcasting? Making a patent invalid due to obviousness.
Even if it's not is it not essential to the implementation of GSM and CDMA standards, meaning the patent would have to be licensed under FRAND making it of relatively low value?
