Radio Base Station, Radio Communication Network System, and Communication Control Method

摘要

A short-distance radio communication in a steady situation and a long-distance radio communication in an unsteady situation are dynamically switched in a radio communication network, and a steady communication and an unsteady communication are realized through the same radio communication network without affecting the respective communication qualities. A radio communication network system includes radio terminals that enable a multihop communication, and a radio base station. The radio base station and the radio terminals communicate with each other by at least two kinds of transmission radio wave powers. The transmission radio wave power is variably controlled according to a measurement data value by sensors of the radio terminals, or a content of data received by a data communication. Also, respective transmission times of the radio terminals, the radio relay station, and the radio base station are determined, and the transmission times do not change even if the transmission radio wave power changes (refer to FIG. 1).

主权项

1. A radio base station that controls a communication with a plurality of radio terminals in a radio communication network system where one radio communication network includes a plurality of radio terminals, and a plurality of the radio communication networks is present, the radio base station comprising:
a communication control unit that executes time synchronization on the plurality of radio terminals included in one radio communication network, and controls the respective radio terminals included in the different radio communication networks to operate at different times, wherein the communication control unit executes the time synchronization among the plurality of radio terminals within the radio communication network to be communicated when executing a communication in each of the plurality of radio communication networks.
