Abstract
A communication apparatus including a function configured to perform data transmission by multicasting to a plurality of apparatuses by radio communication, including: a request reception unit configured to receive a join request from an apparatus that desires multicast data reception from the communication apparatus; a match control unit configured to perform control for matching values of a state variable of layer 2 in the radio communication between the communication apparatus and the apparatus that transmits the join request in response to receiving the join request by the request reception unit.
Claims11
A communication apparatus including a function configured to perform data transmission by multicasting to a plurality of apparatuses by radio communication, comprising:
- a request reception unit configured to receive a join request from an apparatus that desires multicast data reception from the communication apparatus;
- a match control unit configured to perform control for matching values of a state variable of layer 2 in the radio communication between the communication apparatus and the apparatus that transmits the join request in response to receiving the join request by the request reception unit.
A communication apparatus including a function configured to receive data that is transmitted by multicasting from a predetermined apparatus by radio communication, comprising:
- a request transmission unit configured to transmit a join request for performing multicast data reception from the predetermined apparatus;
- and
- a match control unit configured to receive, from the predetermined apparatus that receives the join request, a signal for matching values of a layer 2 state variable in the radio communication between the predetermined apparatus and the communication apparatus, and to use a value of the layer 2 state variable obtained based on the signal for the radio communication.
A layer 2 state control method executed by a communication apparatus including a function configured to perform data transmission by multicasting to a plurality of apparatuses by radio communication, comprising:
- a request reception step of receiving a join request from an apparatus that desires multicast data reception from the communication apparatus;
- a match control step of performing control for matching values of a state variable of layer 2 in the radio communication between the communication apparatus and the apparatus that transmits the join request in response to receiving the join request by the request reception step.
A layer 2 state control method executed by a communication apparatus including a function configured to receive data that is transmitted by multicasting from a predetermined apparatus by radio communication, comprising:
- a request transmission step of transmitting a join request for performing multicast data reception from the predetermined apparatus;
- and
- a match control step of receiving, from the predetermined apparatus that receives the join request, a signal for matching values of a layer 2 state variable in the radio communication between the predetermined apparatus and the communication apparatus, and using a value of the layer 2 state variable obtained based on the signal for the radio communication.
