EMERGENCY COMMUNICATION SYSTEM FOR WIRELESS NETWORK

原文（中文）

A non-access point (AP) device for facilitating wireless communication. The non-AP device has one or more stations (STAs) affiliated with the non-AP device and a processor coupled to the one or more STAs. The non-AP device receives, from an AP device, a frame including an enhanced distributed channel access (EDCA) parameter set that provides prioritized access to a wireless medium for emergency preparedness communication services (EPCS) traffic. The non-AP device transmits a defer signal that causes receiving devices to defer frame transmission. The non-AP device accesses the wireless medium based on the EDCA parameter set. The non-AP device transmits one or more frames including EPCS traffic over the wireless medium.
