A method and apparatus for frequency planning in a multi-system (A, B, C) cellular communications network is disclosed in which a plurality of systems operate over a frequency range comprising a plurality of frequency bands. The systems (A, B, C) each provide communications services to a plurality of subscribers (660) located within substantially the same geographic region. Each of the systems (A, B, C) is assigned one or more of the network frequency bands for use as control channels (700, 730). The systems then share the unassigned frequency bands to provide communications service (710, 720). The systems may share the frequency bands without coordination or synchronization or, as an alternative, the sharing may be controlled by a processor.

L'invention porte sur un procédé et un appareil pour planifier les fréquences dans un réseau de télécommunications cellulaire multi-système (A, B, C), dans lequel une pluralité de systèmes fonctionnent dans une gamme de fréquences comprenant une pluralité de bandes de fréquences. Chacun des systèmes (A, B, C) fournit des services de télécommunications à une pluralité d'abonnés (660), situés sensiblement dans la même région géographique. On attribue à chacun de ces systèmes (A, B, C) une ou plusieurs bandes de fréquences du réseau destinées à servir de canaux de commande (700, 730). Ces systèmes partagent ensuite les bandes de fréquences non attribuées pour fournir un service de télécommunications (710, 720). Ces systèmes peuvent partager les bandes de fréquences sans coordination ni synchronisation. Une autre solution consiste à gérer le partage par processeur.
