Abstract
A communication terminal capable of receiving communication information directed to a own station from a base station even when the own station has a small battery remaining amount and cannot transmit or receive directly to/from a base station and a mobile communication system including the communication terminal and a communication method are provided.
Communication terminals (1, 2) perform wireless communication between the own station and other station and requests a base station (3) to transmit communication information obtained according to the reception state of the own station so as to perform transmission power control. When the transmission power is lower than a relay request setting value obtained from the own station battery remaining amount and the transmission power setting, a relay request is made to other station and communication information directed to the own station is received via the other station.

6. A communication terminal in which wireless communication is mutually performed between an own station and another station, a transmission request of downstream communication information directed to the own station is transmitted via the other station, and communication information directed to the own station is received via the other station, the communication terminal comprising:
a relay request section that requests the other station capable of relaying to relay one or both of downstream communication information directed to the own station and a transmission request of the downstream communication information directed to the own station by a relay request of the own station according to reception states of the own station and the other station and whether a battery remaining amount of the own station is less than a specific threshold value.
-
7. A mobile communication system comprising:
- a plurality of communication terminals that perform wireless communication between an own station and another station; and
a base station that is requested to transmit downstream communication information according to a reception state of the communication terminals, wherein;the communication terminals comprises an other-station relay request section that receives relay enable information, relay setting information, and a battery remaining amount transmitted and obtained from the other station, and requests the other station to relay communication information directed to the own station by transmitting identification information for the base station to identify any of the own station or the other station when the battery remaining amount of the other station is large, and the base station comprises an own/other-station identification transmission section that transmits communication information of the own station to the communication terminal of the own station via the communication terminal of the other station on a basis of the identification information of the own station. - View Dependent Claims (8, 9, 10, 11, 12)
- a plurality of communication terminals that perform wireless communication between an own station and another station; and

13. A communication method which allows first communication with a base station and second communication with other terminal, the communication method comprising:
-
detecting a battery remaining amount, and switching from the first communication to the second communication according to the battery remaining amount.
-
-
14. A communication method in which wireless communication is mutually performed between an own station and other station and communication information directed to the own station is received via the other station, the communication method comprising:
-
receiving relay enable information transmitted from the other station when the own station communicates with a base station, and making a relay request for communication between the own station and the base station from the own station to the other station when a battery remaining amount of the own station is less than a predetermined threshold value.
-
-
15. A communication method in which wireless communication is mutually performed between an own station and other station and a transmission request of downstream communication information directed to the own station is transmitted via the other station, the communication method comprising:
requesting the other station capable of relaying to relay a transmission request of downstream communication information by a relay request of the own station if a value based on a battery remaining amount of the own station is less than a specific threshold value when the own station communicates with a base station.
