Abstract
A beacon signal processing system of reducing wake-up frequency periodically receives a beacon signal from an access point. The beacon signal processing system, according to a data transfer type of a traffic indication message contained in the beacon signal, maintains a sleep mode or only wakes up part of modules of hardware and software necessary for communication for processing.
Claims17
A beacon signal processing system comprising a memory and a processor, wherein a beacon receiver program containing computerized instructions is stored in the memory and configured to be executed by the processor to perform a method, the method comprising:
- periodically receiving, by a beacon receiver, a beacon signal from an access point;
- identifying an information element of data contained in the beacon signal;
- identifying a data transfer type of a traffic indication message contained in the information element;
- determining that data contained in the beacon signal is effective data when the data transfer type is corresponding to a specific data transfer type;
- identifying whether the effective data is necessary data according to a flag corresponding to the specific data transfer type;
- and
- operating in a sleep mode when the effective data is identified as the unnecessary data and operating in an active mode when the effective data is identified as the necessary data.
A filtering method of reducing wake-up frequency, adapted for an electronic device, the filtering method comprising:
- periodically receiving a beacon signal from an access point;
- identifying an information element of data contained in the beacon signal;
- identifying a traffic indication message contained in the information element, and identifying a data transfer type of the traffic indication message;
- determining that data contained in the beacon signal is effective data when the data transfer type is corresponding to a specific data transfer type;
- identifying whether the effective data is necessary data according to a flag corresponding to the specific data transfer type;
- and
- operating in a sleep mode when the effective data is identified as the unnecessary data and operating in an active mode when the effective data is identified as the necessary data.
