Title
(EN) COMMUNICATION SYSTEM AND DUAL-MODE MOBILE STATION
(FR) SYSTEME DE COMMUNICATION ET STATION MOBILE BIMODE
Abstract
(EN) A mobile communications system comprising a first network (2) operable with a first communication protocol, a second network (3) operable with a second communication protocol and a portable communication device (10) operable with the first and the second communication protocols. The first communication protocol results in a lower power consumption by the device whilst in a standby status than the second communication protocol. The device is arranged to default to the first protocol whenever the device enters a standby status. The device may also be arranged to default to the protocol which uses less power in an active status whenever the device enters an active status.
(FR) L'invention concerne un système de communication comprenant un premier réseau (2) fonctionnant avec un premier protocole de communication; un second réseau (3) fonctionnant avec un second protocole de communication; et un appareil portable (10) fonctionnant avec un premier et un second protocoles de communication. Le premier protocole de communication permet une consommation d'énergie plus faible que le second protocole de communication, lorsque le dispositif est en mode veille. L'appareil est conçu de manière à choisir le premier protocole par défaut lorsque l'appareil entre en mode veille. L'appareil peut également être conçu pour choisir, par défaut, le protocole qui utilise le moins d'énergie en mode fonctionnement, lorsque l'appareil entre en mode fonctionnement.
