Abstract

In a wireless LAN system comprising a plurality of base stations and a mobile station, which transmits by wireless, from the base stations, a frame to which a source lower layer address specific to each of the base stations is assigned, the mobile station is provided with a filtering information storing unit for storing filtering information indicating whether or not the source lower layer address is a source lower layer address expected at the mobile station, and a frame filtering unit for selectively receiving the frame based on the filtering information.

Description

technical field [0001] The present invention relates to a wireless local area network system, and more particularly, to a wireless local area network system which includes a plurality of base stations and a mobile station (terminal), and transmits frames from the base stations through wireless links. The invention also relates to a mobile station. Background technique [0002] Generally, a protocol in a LAN (Local Area Network) system is formed of layers such as a data link layer, a network layer, and a transport layer. When a mobile station receives a frame from a base station, the frame is processed at the lowest data link layer, and then at a higher layer, if necessary. [0003] A terminal in a prior art wired LAN system receives all frames on the LAN. The terminal refers at the data link layer to the destination address information included in these frames, and will be a frame sent to its own MAC (Media Access Control) address (unicast frame), and a multicast frame or ...
