Abstract
When it is determined that a power mode is a power save mode, and that a MAC address in a received beacon matches the MAC address of a wireless communication apparatus which newly joins a wireless network, the power mode of all the communication apparatuses which have joined the wireless network is switched from the power save mode to a normal power mode.
Claims16
A communication apparatus comprising:
- a communication unit adapted to directly communicate with a first communication apparatus;
- and
- a controller unit adapted to:
- switch a power mode of said communication unit;
- detect that a second communication apparatus newly joins a network to which said communication apparatus has joined;
- and
- discriminate whether the second communication apparatus has a switching function of a power mode of a communication unit included in the second communication apparatus,
- wherein the power mode of said communication unit is switched from a power save mode to another power mode in accordance with a discrimination result obtained by said controller unit.
A control method for a communication apparatus having a communication unit which directly communicates with communication apparatuses, the method comprising:
- detecting that another communication apparatus joins a network to which the communication apparatus has joined;
- discriminating whether said another communication apparatus has a switching function of a power mode of a communication unit included in said another communication apparatus, and
- switching a power mode of the communication unit from a power save mode to another power mode in accordance with a discrimination result obtained in said discriminating step.
A computer-readable medium storing thereon a program for a communication apparatus having a communication unit which directly communicates with communication apparatuses, the program comprising instructions to execute:
- a detection step of detecting that another communication apparatus joins a network to which the communication apparatus has joined;
- a discriminating step of discriminating whether said another communication apparatus has a switching function of a power mode of a communication unit included in said another communication apparatus;
- and
- a switching step of switching a power mode of the communication unit from a power save mode to another power mode in accordance with a a discrimination result obtained in said discrimination step.
A communication apparatus comprising:
- communication means for directly communicating with a first communication apparatus;
- switching means for switching a power mode of said communication means;
- detection means for detecting that a second communication apparatus newly joins a network to which said communication apparatus has joined;
- and
- discrimination means for discriminating whether the second communication apparatus has a switching function of a power mode of a communication means included in the second communication apparatus,
- wherein said switching means switches the power mode of said communication means from a power save mode to another power mode in accordance with and a discrimination result obtained by said discrimination means.
