Abstract
A frame blocking method for wireless device comprises the steps of: receiving a frame; determining if a size of the frame complies with a predetermined size? If “YES” then proceed; determining if the frame complies with a predetermined frame format? If “YES” then proceed; determining if an IP address contained in the frame is the same with a currently using IP address pre-stored in the client device? If “NO” then ignore the frame, if “YES” then handle the frame by normal operations. Therefore, unnecessary frames can be blocked as early as possible so as to save power and improve overall communicating quality.
Claims14
A method of frame blocking for a wireless device, the wireless device having a predetermined IP address and a predetermined MAC address pre-recorded therein, the method comprising the following steps executed by the wireless device:
- (A) receiving a frame from the outside;
- (B) determining whether a size of the frame is consistent with a predetermined size, and if “yes”, then executing step (C), and otherwise, executing step (F);
- (C) determining whether a header included in the frame complies with a predetermined format, and if “yes”, then executing step (D), and otherwise, executing step the (F);
- (D) determining whether an IP address included in the frame is identical to the predetermined IP address, and if “yes”, then executing step (E), and otherwise, executing the step (F);
- (E) deleting the frame and returning to the step (A);
- and
- (F) processing the received frame through a normal procedure and returning to the step (A).
A method of frame blocking for a wireless device, the wireless device having a predetermined IP address and a predetermined MAC address pre-recorded therein, and the method comprising the following steps executed by the wireless device:
- (a) receiving a frame, which at least contains therein the following information:
- frame format information, MAC address information and IP address information;
- (b) determining whether the frame format information complies with a predetermined frame format, and if “yes”, then executing step (c), and otherwise, executing step (e);
- (c) determining whether the IP address included in the frame complies with the IP address currently used, and if “yes”, then executing step (d), and otherwise, executing the step (e);
- (d) deleting the frame and returning to the step (a);
- and
- (e) processing the received frame through a normal procedure and returning to the step (a).
