The present invention is directed to a digital wireless telecommunications system that includes a plurality of base station of differing spectral capabilities, and a plurality of remote stations capable of transmitting data to and receiving transmissions from the plurality of base stations. The invention herein provides a method for remote station hand-off between the base stations of a narrower spectral capacity and base stations of a wider spectral capacity. A method is provided for a wireless telecommunications infrastructure to facilitate a remote station hand-off from a set of narrowband compliant base stations to at least one wideband compliant base station while a remote station is in the coverage area of both types of base stations. Additionally, the invention herein provides remote station apparatus, base station apparatus, and base station controller apparatus for performing the handoff methodology of the present invention.
L'invention concerne un système de télécommunications hertziennes numériques comprenant plusieurs stations de base à possibilités spectrales différentes, et plusieurs stations distantes pouvant émettre vers et recevoir des données des stations de base. Elle concerne aussi un procédé destiné au transfert d'appel de station distante entre les stations de base à capacité spectrale étroite et des stations de base à capacité spectrale plus large. Elle concerne encore un procédé destiné à une infrastructure de télécommunications hertziennes afin de faciliter un transfert d'appel de station distante à partir d'un ensemble de stations de base conformes à bande étroite vers au moins une station de base conforme à bande large alors qu'une station distante est dans la zone de couverture des deux types de station de base. Elle concerne enfin un appareil de station distante, un appareil de station de base, et un appareil de commande de station de base, destinés à mettre en oeuvre la méthodologie de transfert de l'invention.
