Title
(EN) PRESENCE-AWARE CELLULAR COMMUNICATION SYSTEM AND METHOD
(FR) SYSTEME DE COMMUNICATION CELLULAIRE SENSIBLE À LA PRESENCE ET PROCEDE ASSOCIE
Abstract
(EN) A cellular communication system comprises a network supporting user equipment over an air interface, the network having a hierarchical cell arrangement with overlay cells and underlay cells. An underlay base station (105) is associated with a subset of registered user equipment. An activation server (117) switches the underlay base station (105) between an inactive mode and an active mode in response to detecting that registered user equipment meets a location criterion. The underlay base station (105) only supports user equipment when in the active mode, e.g., it may only transmit a pilot signal in this mode. Interference and power consumption may be substantially reduced by sending the base station (105) into the inactive mode thereby resulting in increased capacity of the cellular communication system as a whole.
(FR) L'invention concerne un système de communication cellulaire qui comprend un équipement utilisateur supportant un réseau sur une interface aérienne, ledit réseau ayant une disposition cellulaire hiérarchique avec des cellules sus-jacentes et sous-jacentes. Une station de base sous-jacente (105) est associée à un sous-ensemble d'équipement utilisateur enregistré. Un serveur d'activation (117) commute la station de base sous-jacente (105)d'un mode inactif à un mode actif en réponse à la détection du fait que l'équipement utilisateur enregistré satisfait à un critère de localisation. La station de base sous-jacente (105) ne supporte l'équipement utilisateur qu'en mode actif, par exemple, elle peut ne transmettre un signal pilote que dans ce mode. Les interférences et la consommation d'énergie peuvent être sensiblement réduites par l'envoi de la station de base (105) en mode inactif, le résultat étant une capacité accrue du système de communication cellulaire dans son ensemble.
