Wireless Priority Service Overview
Reliable and secure telecommunications systems are necessary for effectively managing national security incidents and emergencies. The National Security and Emergency Preparedness (NS/EP) is a set of voice, video, and data services that belong to services available from public packet-switched Service Providers and that provide priority services in support of NS/EP communications. The NS/EP communication systems include landline, wireless, broadcast, and cable television, radio, public safety systems, satellite communications, and the Internet.
Wireless Priority Services (WPS) is one of the NS/EP communications programs that provide personnel priority access and prioritized processing in all nationwide and several regional cellular networks, increasing the probability of call completion.
WPS users, also known as first responders, are responsible for the command and control functions that are critical to the management of response to national security and emergencies.
The CPS 21.1 release supports enabling derived ARP for Wireless priority services on Cisco Policy Suite (CPS – PCRF).
