Patent

CA 2305873

A device for communicating a common channel message in a CDMA communication system. The device comprises a base station transmitter including a specific channel transmitter for outputting a channel signal with second transmission power at a predetermined time duration and outputting the channel signal with first transmission power at other time duration, and a common channel transmitter for transmitting a common channel message at an assigned slot duration; and a receiver of a mobile station, wherein a power supply voltage is provided to the receiver at the duration where the specific channel is received with the second transmission power and the assigned slot duration to enable the receiver, wherein the power supply voltage to the receiver is cut off at other duration so as to allow the receiver to operate in a sleep mode.

L'invention porte sur un dispositif de transmission d'un message sur canal commun d'un système de transmission AMCR comportant: un émetteur de station de base comprenant un émetteur sur canal spécifique émettant un signal d'une deuxième puissance pendant un temps prédéterminé et un signal à une première puissance pendant un deuxième temps; un émetteur sur canal commun transmettant un message sur canal commun pendant un créneau de temps attribué; ainsi qu'un récepteur de station mobile alimenté pendant le temps de réception du canal spécifique à la deuxième puissance d'émission, l'alimentation du récepteur étant coupée pendant les autres périodes où il fonctionne à l'état de veille.
