Abstract
An AN (Access Network) controlled by a communication control apparatus and communicating with a AT Access Terminal), wherein the AN receives control information including information for allocating communication information from the communication control apparatus, and the AN transmits transmission cycle information for transmitting the communication information in a predetermined transmission cycle to the AT and allocates the communication information in the predetermined transmission cycle based on the control information received from the communication control apparatus to send the communication information to the AT.
Claims24
An AN (Access Network) controlled by a communication control apparatus and communicating with a AT Access Terminal), wherein
- the AN receives control information including information for allocating communication information from the communication control apparatus, and
- the AN transmits transmission cycle information for transmitting the communication information in a predetermined transmission cycle to the AT and allocates the communication information in the predetermined transmission cycle based on the control information received from the communication control apparatus to send the communication information to the AT.
An AN controlled by a communication control apparatus and communicating with a plurality of AT(Access Terminal)s, wherein
- the AN receives control information including information for multiplexing communication information from the communication control apparatus, and
- the AN transmits transmission cycle information for transmitting the communication information in a predetermined transmission cycle to the ATs and multiplexes the communication information in the predetermined transmission cycle based on the control information received from the communication control apparatus to send it to the ATs.
An AT communicating with an controlled by a communication control apparatus, wherein
- the AT receives control information including a predetermined transmission cycle, a transmission slot number indicating a length of communication information, and a transmission timing indicating a period allocated for the communication information in the predetermined transmission cycle, and
- the AT extracts the communication information specified by the transmission slot number and the transmission timing in the control information from plural piece of communication information allocated in the predetermined cycle and sent from the AN to receive the extracted communication information.
An AT communicating with an controlled by a communication control apparatus, wherein
- the AT receives control information including a predetermined transmission cycle, a transmission slot number indicating a length of communication information, and a transmission timing indicating a period allocated for the communication information in the predetermined transmission cycle, and
- the AT extracts the communication information specified by the transmission slot number and the transmission timing in the control information from plural piece of communication information multiplexed in the predetermined cycle and sent from the AN to receive the extracted communication information.
A radio communication method performed by an AN wirelessly communicating with an AT and a communication control apparatus controlling the AN, comprising the steps of:
- sending, by the communication control apparatus, transmission cycle information and control information to the AN, the transmission cycle information being for transmitting communication information to the AT in a predetermined transmission cycle and the control information including information for allocating the communication information;
- sending, by the AN, the transmission cycle information received from the communication control apparatus to the AT;
- and
- allocating, by the AN, the communication information based on the control information received from the communication control apparatus and sends it in the predetermined transmission cycle to the AT.
A radio communication method performed by an AN for wirelessly communicating with a plurality of ATs and a communication control apparatus controlling the AN, comprising the steps of:
- sending, by the communication control apparatus, transmission cycle information and control information to the AN, the transmission cycle information being for transmitting communication information to the ATs in a predetermined transmission cycle and the control information including information for multiplexing the communication information;
