  • Wireless terminal call method and wireless access system capable of greatly reducing standby power consumption of wireless terminals in a call standby state without increasing call delay time
    Patent number: 8774089
    Abstract: A wireless terminal receives a first broadcast signal transmitted from a wireless base station; detects whether a part of a wireless terminal ID of the own wireless terminal is included in the first broadcast signal received in the broadcast signal reception or not and determines that the second broadcast signal is to be continuously received when the part of the wireless terminal ID is included; and receives the second broadcast signal when it is determined in the broadcast signal determination that the second broadcast signal is to be received, stops receiving data transmitted from the wireless base station when assignment information to be transmitted to the own wireless terminal is not present in the received second broadcast signal, and receives data transmitted from the wireless base station to the own wireless terminal based on the information on the assignment position of the wireless slot included in the second broadcast signal when the assignment information to be transmitted to the own wireless ter

  • Wireless communication method, base station apparatus and wireless communication system
    Patent number: 8660098
    Abstract: A base station apparatus includes a base-station receiver which receives information indicating the occurrence of the given event in the wireless terminal device, the information being transmitted from the wireless terminal device using the common slot. The base station apparatus includes a base-station transmission and reception manager which determines the number of random slots assigned as random slots to transmit the bandwidth request information for the given event among random slots in the random access period, based on the occurrence of the given event received by the base-station receiver. The base station apparatus includes a base-station transmitter which transmits, in the base station apparatus, information on the assigned random slots to the wireless terminal device of random access period.

  • Wireless communication method, wireless communication system, base station, and terminal station
    Patent number: 8532140
    Abstract: A base station performs bandwidth assignment for each terminal station or each wireless link even when the base station does not receive a bandwidth request in random access from the terminal station in the demand assignment period present in a specific period in which a transmission frequency of data to transmit is high, the specific period being specified for each terminal station or each wireless link between the terminal station and the base station, and the terminal station transmits at least one of bandwidth request information and the data to transmit in a bandwidth assigned by the base station.
