Intra cell handover and channel allocation to reduce interference

摘要

A method of reducing interference in a cellular radio communication including performing a courtesy handover of a first call to another channel to reduce interference in a second call when the presence of the first call on the same frequency as the second call causes the interference in the second call. Also, a method of setting up a call which permits a retry to a macro cell when a channel of sufficient quality is not found in a micro cell.
