Abstract
(EN)
In a cellular radio system a message indicating a change of cell size can be transmitted to a number of affected cells, in particular, neighboring cells. The affected cells receiving such a message can be adapted to use the information in the message when determining self-optimization parameters used for control purposes. Hereby, better response times can be achieved without reducing noise sensitivity.
(FR)
L'invention concerne un système radio cellulaire où un message indiquant une modification de la taille des cellules peut être envoyé à un certain nombre de cellules affectées, en particulier des cellules voisines. Les cellules affectées recevant un tel message peuvent être prévues pour utiliser l'information contenue dans le message lorsqu'elles déterminent des paramètres d'auto-‌optimisation utilisés à des fins de commande. De meilleurs temps de réponse peuvent ainsi être réalisés sans réduire la sensibilité au bruit.
