Abstract

The present invention provides an infrastructure service information communication device and an infrastructure service information communication method. The infrastructure service information communication device comprises: a service processing module, configured to generate a broadcast message, wherein a physical frame header and/or a media access control frame header of the broadcast message comprise an identification information bit, the value of the identification information bit is a first value when the broadcast message is an infrastructure service information discovery message, and the infrastructure service information discovery message comprises specific information of infrastructure service information; and a wireless transceiving module, configured to exchange data with the outside of the infrastructure service information communication device, wherein the service processing module transmits the broadcast message via the wireless transceiving module. The present invention allows an STA to save a large amount of power in a process of carrying out infrastructure network service information discovery, which is also favorable for power saving of those STAs that are not engaged in the infrastructure network service information discovery.
