Title:
無線端末の遠隔電力低下制御
Document Type and Number:
Japanese Patent JP3746438
Kind Code:
B2
Abstract:
On instructions obtained from a subscriber, a wireless terminal service provider sends a power-down signal to a wireless terminal. Upon receipt of the power-down signal, the wireless terminal goes into a sleep state. In this state, all monitoring functions other than time, date and elapsed time are turned off. The power-down signal sets a clock, which can be located within the wireless terminal, to awaken the wireless terminal at the end of a discrete interval of time by powering-up the monitoring circuits. The wireless terminal service provider, by knowing the power-down/power-up time cycle of the wireless terminal, can alert a party attempting to contact the wireless terminal during the power-down period that the called party cannot be reached. The wireless terminal service provider can also offer various options to the calling party, such as providing the time when the called wireless terminal will next be on, offer to take a message which can be sent when the called wireless terminal is next on, offer to cancel any further attempt to send the message to the called wireless terminal, etc. Normally, the power-down control signal will condition the wireless terminal to assume the sleep state for a discrete interval of time. Extended intervals of time can be obtained by resending the control signal at the end of the discrete interval of time. If desired, a two-part control signal can be sent to the wireless terminal where one part conditions the wireless terminal to assume the power-down state and the other part controls the duration of the power-down state.
