Abstract
A beacon signal minimization method and a beacon signal processing system utilizing a changed beacon element periodically receives a beacon signal from an access point and maintains network connectivity in a sleep mode, or only wakes up modules of hardware and software necessary for communication, by comparing whether an information element contained in the beacon signal is different from information stored in advance.
Claims9
A beacon signal processing system comprising a memory, a processor, and an information table unit configured to store a necessary information element for communication with the access point, 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;
- generating a result value of performing a checksum on the information element, and identifying whether the information element is changed according to the result value;
- enabling a sleep mode of the processor according to whether or not the information element is changed,
- comparing the necessary information element with the information element, and
- identifying whether the information element is the necessary information element.
A non-transitory computer-readable recording medium, recording a program for performing a method, the method comprising:
- periodically receiving a beacon signal from an access point;
- identifying an information element of data contained in the beacon signal;
- generating a result value of performing a checksum on the information element, and identifying whether the information element is changed according to the result value;
- operating in a sleep mode according to whether or not the information element is changed,
- comparing a necessary information element with the information element, and
- identifying whether the information element is the necessary information element,
- wherein the necessary information element is stored in an information table for communications with the access point.
