Abstract
Channels are assigned ( ) to a subject cellular network ( ) after taking into account the locked/unlocked status of cells ( ). Channels are assigned to locked cells ( ) in accordance with a prearranged assignment plan ( ). After this assignment, one unlocked cell ( ) is selected ( ) at a time. An available channels list is built ( ) for the selected unlocked cell ( ), and a channel is selected ( ) from this list for assignment to the selected unlocked cell ( ). The available channels list is built ( ) by evaluating all channels in the network ( ) one at a time to determine if their assignment to the selected unlocked cell ( ) would cause undue interference in any other cell ( ) of the network ( ). If interference worse than a minimum system threshold is detected ( ) in another cell ( ), a channel is made unavailable for assignment unless it is a locked cell ( ). For a locked cell it is made unavailable ( ) if the channel assignment would worsen interference by more than an offset value.
