Abstract

Système de radiocommunications cellulaire qui comprend un certain nombre de stations de base (BS) et un certain nombre de stations mobiles (MS), ainsi qu'un certain nombre de cellules qui sont disposées dans au moins deux couches différentes de préférence. Des connexions au sein dudit système de communications peuvent être transmises d'une cellule à une autre et au moins un paramètre de signal est mesuré ou surveillé. Au moins un seuil est donné au moins pour chaque cellule dans les couches inférieures, ou au moins un paramètre de signal. Ledit système comprend en outre un dispositif permettant de prendre des décisions de transmission et de commander lesdites décisions, qui comporte une règle de classement prioritaire basée sur un certain nombre de critères dont l'un est fondé sur une comparaison d'une valeur surveillée (Io) d'un paramètre de signal et de la valeur seuil (Io<tr>) de la cellule de desserte, et dont un deuxième est fondé sur une comparaison de la valeur surveillée d'un paramètre de signal (Ii) et de la valeur seuil correspondante (Ii<tr>) pour la cellule voisine, les transmissions étant régies par la règle de classement prioritaire si bien que l'on obtient un transfert systématique aussi bien vers le haut que vers le bas entre les couches.
