Abstract

Oggetto dell'invenzione è un radiotelefono portatile (101) il quale funziona in cooperazione con una stazione di base senza filo (cordless) (115) attraverso l'area di copertura locale con l'impiego dei canali delle frequenze cellulari. Sia il radiotelefono portatile (101) sia la stazione di base senza filo (115) esplorano i canali disponibili per generare delle separate liste di priorità. Il radiotelefono portatile (101) e la stazione di base senza filo (115) suddividono i canali disponibili in categorie nella propria rispettiva lista di priorità dal migliore al peggiore. Le liste di priorità sia dal radiotelefono portatile (101) sia dalla stazione di base senza filo (115) vengono combinate per formare una lista di priorità principale o master. Il sistema telefonico senza filo quindi assegna il canale disponibile più libero ricavandolo dalla lista di priorità principale per l'impiego nel sistema telefonico senza filo. Perciò, le interferenze contro e dal sistema cellulare e da altri utenti delle frequenze cellulari vengono ridotte al minimo e viene eliminata la necessità di una pianificazione delle frequenze.
