Abstract

La présente invention a trait à un appareil de terminal de communication mobile capable de supprimer la consommation de courant lors de l'activation d'un module de communication. L'appareil comporte une module de communication de type d'accès multiple par répartition en code à large bande (WCDMA) (110) et un module de communication de réseau local (LAN) (120). Le module de communication WCDMA (110) comprend une partie de radiotéléphone mobile (111) qui reçoit un signal de réveil transmis par une station de base; et une partie de commande de réveil de téléphone mobile (112) qui active, en fonction du signal de réveil reçu par la partie de radiotéléphone mobile (111), le module de communication WCDMA (110). Le module de communication LAN (120) comprend une partie de radio de réseau local sans fil (WLAN) (121) qui transmet une signal de recherche de point d'accès (AP) pour la recherche d'un point d'accès d'un réseau local sans fil; et une partie de commande de période de recherche de point d'accès de réseau local sans fil (122) qui commande la période pendant laquelle le signal de recherche de point d'accès doit être transmis. Une unité centrale de traitement hôte (140) commande la partie de commande de période de recherche de point d'accès de réseau local sans fil (122) de sorte que la partie radio de réseau local sans fil (121) transmet le signal de recherche de point d'accès en synchronisme avec la période pendant laquelle la partie de radiotéléphone mobile (111) reçoit le signal de réveil.
