Abstract
A method and apparatus for frequency planning in a multi-system cellular communications network is disclosed in which a plurality of systems operate over a frequency range comprising a plurality of frequency bands. The systems each provide communications services to a plurality of subscribers located within substantially the same geographic region. Each of the systems is assigned one or more of the network frequency bands for use as control channels. The systems then share the unassigned frequency bands to provide communications service. The systems may share the frequency bands without coordination or synchronization or, as an alternative, the sharing may be controlled by a processor.
