A radio terminal unit and a radio communication system, enabling power savings, the improvement of the quality of real-time communication such as voice communication, and the reduction of transmission delays which often occur when a plurality of radio terminal units are connected to one radio base station. A radio terminal unit comprises a communication control section for controlling a radio interface section to transmit a control packet using a timer value.

An intermittent receiving interval for each radio terminal is set according to the operation mode of each application running on the radio terminal. Consequently, the intermittent receiving interval can be changed in cooperation with the operation mode of each application. Thus, power-saving control for the radio terminal can be carried out precisely. In addition, the radio terminal can assign priorities to data transmitted from the radio base station. The priorities are set according to the operation mode of each application running on the radio terminal, and the packets of real-time communication can be transmitted preferentially.

A wireless mobile communication device comprises first and second wireless interfaces that are individually powered from a battery. A controller sets the first wireless interface in a power-ON state for establishing a first wireless link with a first base station, makes a determination whether a handover is necessary from the first base station to a second base station, sets the second wireless interface in a power-ON state in response to the determination that the handover is necessary for making a search for the second base station, and sets the first wireless interface in a power-OFF state when the second wireless interface has established a second wireless link with the second base station. A wireless LAN module is connected to the controller for establishing a session with a remote communication device via the first and second wireless links.

There is provided a wireless communication system including a radio-signal base station, and a mobile wireless terminal operating in a power-saving mode in which the mobile wireless terminal intermittently receives packet signals, and in a normal mode in which the mobile wireless terminal regularly receives packet signals. When the radio-signal base station receives packet signals addressed to a mobile wireless terminal being in the power-saving mode, the radio-signal base station temporarily stores the received packet signals. The mobile wireless terminal requests the radio-signal base station to transmit the packet signals thereto, receives a part of the packet signal from the radio-signal base station, and, if the mobile wireless terminal judges that it would be necessary to carry out real-time communication for receiving entirety of the packet signals, the mobile wireless terminal transfers to the normal mode from the power-saving mode for receiving entirety of the packet signals.

Wireless communication system and method of making wireless communication

The wireless base station determines whether or not each wireless terminal station accessing to the wireless base station is authenticated for the access to the LAN. Thereafter, the wireless base station stores the result of the determination to the packet distributing table. When the wireless base station receives a packet from any wireless terminal station, the wireless base station determines whether or not the wireless terminal station transmitted the packet is authenticated. If the wireless terminal station is authenticated, the packet is transmitted to the LAN. On the other hand, if the wireless terminal station is not authenticated, the packet is transmitted to the server or the gateway.

A power saving method in a wireless LAN system is disclosed for permitting a terminal station to promptly transition to a doze state irrespective of the presence or absence of data destined to the terminal station in a base station. Upon receipt of a PS-Poll signal from a terminal station subordinate to a base station for prompting a transmission of data destined to the terminal station, the base station transmits an ACK signal to the terminal station for indicating a successful reception of the PS-Poll signal. Further, the base station transmits a data frame including data destined to the terminal station when there is such data, or transmits an empty data frame when there is no data destined to the terminal station. Then, upon receipt of the data frame (including the empty data frame), the terminal station transmits an ACK signal to the base station, and then transitions to the doze state in which a transmission/reception function is made inoperative.

An operation mode determination section determines whether real-time processing is necessary or unnecessary based on parameters of all active communication applications set by a communication application section. When real-time processing is necessary, a communication control section transmits a PS-Poll as a control packet for requesting delivery of packets to a radio base station, and turns on the power of a radio interface section so as to receive packets buffered by the radio base station. When real-time processing is unnecessary, the communication control section turns off the power of the radio interface section, and carries out intermittent receiving operation based on beacons transmitted from the radio base station.
