Title
(EN) METHOD AND APPARATUS FOR BALANCING THE FORWARD LINK HANDOFF BOUNDARY TO THE REVERSE LINK HANDOFF BOUNDARY IN A CELLULAR COMMUNICATION SYSTEM
(FR) PROCEDE ET DISPOSITIF D'ADAPTATION DE LA LIMITE DE TRANSFERT DE LIAISON VERS L'AVANT A LA LIMITE DE TRANSFERT DE LIAISON INVERSE DANS UN SYSTEME DE TELECOMMUNICATIONS CELLULAIRE
Abstract
(EN)
A method and apparatus for matching the location of the forward link handoff boundary to the reverse link handoff boundary. A system constant is chosen which defines the product of the received power and the transmitted pilot power at every base station. The reverse link power level is measured at the base station and the forward link power level is compensated for the reverse link loading to maintain the constant product. Thereby the forward link handoff boundary to the reverse link handoff boundary are aligned to the same location.

Procédé et dispositif servant à adapter l'emplacement de la limite de transfert de liaison vers l'avant à la limite de transfert de liaison inverse. On sélectionne une constante de système définissant le produit de la puissance reçue et de la puissance pilote transmise au niveau de toutes les stations de base. On mesure le niveau de puissance de la liaison inverse au niveau de la station de base et on équilibre le niveau de puissance de la liaison vers l'avant par rapport à la charge de la liaison inverse, de façon à conserver le produit de la constante. Ceci permet d'aligner au niveau du même emplacement la limite de transfert de liaison vers l'avant par rapport à la limite de transfert de liaison inverse.
