Wi-Fi 7 has introduced the Emergency Preparedness Communication Service (EPCS) in support of End-to-End (E2E) Multimedia Priority Services Communications (MPS), which provides preferred or prioritized channel access (PCA) over public/private Wi-Fi networks in emergency service (ES) or enhanced 911 (E911) scenarios. While EPCS may be useful in providing a priority/Quality of Service (QoS) in ES/E911 scenarios, the service does not address challenges of fast access to a wireless local area network (WLAN) in certain environments, such OpenRoaming environments. This proposal provides techniques through which OpenRoaming can be extended to support EPCS in a straightforward manner that can improve service access speed.
