Individual cells can have half-rate "licences" applied to them, which allows
them to use HR as and when needed. When the network decides that cell is
carrying more traffic than its available capacity can support at full-rate,
it will start using HR. There may well also be a cost implication to using
HR in this way.

On the other hand, it's quite possible to use HR quite widely without the
end user noticing. There is definitely a balancing act to be achieved.

Is this a regulatory licence? If so, is it possible to view a list of
licences granted?

Is it used in this way in practice, and how often does this happen?

It's more likely to be a patent/software license, if it's for a
compressed voice codec.

It is sometimes quite noticeable when my 3G phone drops back to 2G -
I suspect that is the effect of HR codecs..
