POWER CONTROL SYSTEM IN WIRELESS COMMUNICATION

A mobile terminal makes inquiries of the out-of-communication-area time for a base station when the strength of radiowave transmitted from the base station drops below the specified value. The out-of-communication-area time is a time required for the mobile terminal to pass through a region out of t...

Zusammenfassung:	A mobile terminal makes inquiries of the out-of-communication-area time for a base station when the strength of radiowave transmitted from the base station drops below the specified value. The out-of-communication-area time is a time required for the mobile terminal to pass through a region out of the communication area.In response to the inquiries from the mobile terminal, the base station calculates the out-of-communication-area time for giving notice to the mobile terminal. While the out-of-communication-area time goes on, the mobile terminal places its operation mode into a low power mode. Un terminal mobile effectue des demandes du temps d'une zone hors communication pour une station de base lorsque l'intensité d'une onde radio transmise depuis la station de base baisse au-dessous de la valeur spécifiée. Le temps d'une zone hors communication est un temps requis pour que le terminal mobile traverse une région hors de la zone de communication. En réponse aux demandes du terminal mobile, la station de base calcule le temps de la zone hors communication pour l'annoncer au terminal mobile. Tandis que le temps d'une zone hors communication continue, le terminal mobile place son mode d'exploitation dans un mode de puissance faible.
