Notification system, and method for remotely turning on cellular phone being in power-off state and cellular phone thereof

Abstract

In a notification system for communicating between a sender cellular phone possessed by a sending person and a receiver cellular phone possessed by a receiving person, the sender cellular phone, which is possessed by the sending person who wants to communicate with the receiving person, is allowed to transmit an ON state indication signal indicating to switch a main power source to be in an ON state through a radio wave to the receiver cellular phone being in an OFF state. Thus, a main power source of the receiver cellular phone can be remotely turned ON.

1 . A notification system for communicating between a sender cellular phone and a receiver cellular phone comprising: 
 a system configuration for allowing said sender cellular phone to transmit a power-ON signal indicating to said receiver cellular phone to switch ON a main power source of said receiver cellular phone through a radio wave to said receiver cellular phone when said receiver cellular phone is in an OFF state,    such that said main power source of said receiver cellular phone is remotely placed in an ON state upon receipt of the power-ON signal.    
   
   
       2 . The notification system according to  claim 1 , wherein after said receiver cellular phone enters said ON state, said receiver cellular phone is notified that a call is received.  
   
   
       3 . A notification system for communicating between a sender cellular phone and a receiver cellular phone comprising: 
 a base station controlling device for receiving receiver information concerning said receiver cellular phone, and for controlling a base station covering an area indicated in said receiver information;    a sub-system configuration in said base station for sending a power-ON signal based on said receiver information received from said base station controlling device; and    a device configuration in said receiver cellular phone for receiving said power-ON signal from said base station, and entering an ON state upon receipt of said power-ON signal, even if a main power source of said receiver cellular phone is in an OFF state.    
   
   
       4 . The notification system according to  claim 3 , wherein said receiver information includes at least one of a receiver cellular phone telephone number, a password to access said receiver cellular phone, and area information indicating an area where said receiver cellular phone is predicted to be.  
   
   
       5 . A method for communicating between a sender cellular phone and a receiver cellular phone comprising: 
 transmitting, by said sender cellular phone, a signal with an embedded power-ON indication signal indicating to said receiver cellular phone to switch ON a main power source of said receiver cellular phone through a radio wave to said receiver cellular phone; and turning on said main power source of said receiver cellular phone upon receipt of said power-ON indication signal.    
   
   
       6 . The method according to  claim 5 , further comprising: confirming that said main power source of said receiver cellular phone to be notified is in an OFF state.  
   
   
       7 . The method according to  claim 5 , wherein after said receiver cellular phone enters in said ON state, the method further comprising notifying said receiver cellular phone that a call is received.  
   
   
       8 . A cellular phone comprising a device configuration for receiving a power-ON signal from a base station that instructs said cellular phone to enter an ON state, and, upon receipt of said power-ON signal, switching a main power source to be in said ON state even if said main power source is in an OFF state.  
   
   
       9 . The cellular phone according to  claim 8 , further comprising: 
 a synchronization establishing circuit for establishing synchronization with at least said base station even if said main power source is in said OFF state;    a main power source ON information detecting section for extracting main power source ON information from a radio wave transmitted from said base station; and    a power source section for supplying electric power to said main power source ON information detecting section and a location information detecting section to be kept in an ON-state, even if said main power source is in said OFF state, and for turning ON said main power source when said main power source ON information is input from said main power source ON information detecting section.    
   
   
       10 . The cellular phone according to  claim 9 , wherein said cellular phone is used as a receiver cellular phone in a notification system for communicating between a sender cellular phone and said receiver cellular phone, wherein said notification system comprises: 
 a system configuration for allowing said sender cellular phone to transmit said power-ON signal instructing said receiver cellular phone to switch ON a main power source of said receiver cellular phone through a radio wave to said receiver cellular phone, such that a main power source of said receiver cellular phone is remotely turned ON upon receipt of said power-ON signal.    
   
   
       11 . The method according to  claim 5 , wherein an OFF state status indication can be accessed from said receiver cellular phone.
