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.

[ What is claimed is:] [17.] In a cellular radio communication network comprising a plurality of systems each providing service within a common geographic area, and operating within a frequency range comprising a plurality of frequency bands, a method of allocating frequency bands to said systems, said method comprising the steps of:assigning one or more first frequency bands to each of said systems, wherein said first frequency bands are used exclusively for control channels within the systems to which each is assigned; andallocating one or more second frequency bands to said systems on a shared basis, wherein saidsecond frequency bands are used for traffic channels within the system to which each is currently allocated.
