Broadcast information delivering system

A broadcast information delivering system comprising:

• a provider for generating a broadcast frame containing a frame header and a plurality of sub-frames following the frame header, each of said sub-frames containing different broadcast information to each other, and said frame header including guidance information of the broadcast information contained in said sub-frames;
• and
• a wireless base station for communicating with a wireless terminal, control information through at least one control channel in each of uplink and downlink directions, and user information through a pair of uplink and downlink traffic channels assigned to the wireless terminal,
• wherein said wireless base station comprises:
• a control channel transmitter circuit for transmitting system information and broadcast control information to said downlink control channel, said broadcast control information defining a transmission condition of a broadcast frame, and
• a broadcast channel transmitter circuit for transmitting the broadcast generated by said provided to a specific channel defined by said broadcast control information, in accordance with said transmission condition,
• wherein said broadcast control information includes information for specifying said specific channel and information for indicating a transmission time of said broadcast frame, as said transmission condition,
• wherein said frame header includes classification information for indicating a category of the broadcast information contained in each of said the sub-frames and time information for indicating a transmission timing of each of said sub-frames, as said guidance information, and
• wherein each wireless terminal comprises:
• a control channel receiver circuit for receiving the control information from said control channel,
• a broadcast channel receiver circuit for receiving the broadcast frame from said broadcast channel based on the broadcast control information received by said control channel receiver circuit, and for selectively receiving broadcast information contained in a specific one of said sub-frames in accordance with guidance information of the broadcast frame,
• an input device for designating one of the broadcast information, and
• a power supply controller for halting the power supply to said broadcast channel receiver circuit for a period after receiving the frame header of said broadcast frame until the transmission timing of a sub-frame which includes said designated one of the broadcast information.

A broadcast communication system for communicating between a wireless base station and one of a plurality of wireless terminals, control information through at least one control channel and user information through a pair of uplink and downlink traffic channels assigned to each of said wireless terminals, said wireless base station comprising:

• a control channel transmitter circuit for
• transmitting to said control channel, broadcast control information for defining a transmission condition of a broadcast frame;
• and
• a broadcast channel transmitter circuit for transmitting the broadcast frame, which is supplied from a broadcast information supplying system to deliver to unspecified wireless terminals, in accordance with said transmission condition to a broadcast channel which is also specified by said transmission condition, said broadcast frame comprising a frame header and a plurality of sub-frames following the frame header, each of said sub-frames containing different broadcast information to each other, and said frame header including guidance information concerning the broadcast information contained in said respective sub-frames,
• wherein each wireless terminal comprises:
• a control channel receiver circuit for receiving the control information from said control channel,
• a broadcast channel receiver circuit for receiving the broadcast frame from said broadcast channel based on the broadcast control information received by said control channel receiver circuit, and for selectively receiving broadcast information contained in a specific one of said sub-frames in accordance with guidance information of the broadcast frame,
• a storage for storing the broadcast information received by said broadcast channel receiver circuit,
• an output device for outputting the broadcast information stored in said storage,
• wherein said frame header of the broadcast frame includes, as the guidance information, identification information for identifying the broadcast information contained in each of said sub-frames, and time information for indicating a transmission timing of said respective sub-frames,
• an input device for designating one of the broadcast information, and
• a power supply controller for halting the power supply to said broadcast channel receiver circuit for a period after receiving the frame header of said broadcast frame until the transmission timing of a sub-frame which includes said designated one of the broadcast information.

A wireless terminal apparatus that communicates with a wireless base station, control information through at least one control channel and user information through a pair of uplink and downlink traffic channels assigned thereto, said wireless terminal apparatus comprising:

• a control channel receiver circuit for receiving the control information from said control channel;
• a broadcast frame from a broadcast channel specified by broadcast control information received by said control channel receiver circuit, and selectively receiving broadcast information contained in a specific one of sub-frames in the broadcast frame in accordance with guidance information contained in the broadcast frame;
• a storage for storing the broadcast information received by said broadcast channel receiver circuit;
• an output device for outputting the broadcast information stored in the said storage,
• wherein the frame header of said broadcast frame includes as the guidance information, identification information for identifying the broadcast information contained in each of said sub-frames, and time information for indicating a transmission timing of each of said sub-frames,
• an input device for designating one of said broadcast information to be received;
• and
• a power supply controller for halting the power supply to said broadcast channel receiver circuit for a period after receiving a frame header of the broadcast frame until the transmission timing of specified one of said sub-frames which contains the designated broadcast information.
