The Department of Homeland Security (DHS) has issued a Request for Information (RFI) for future service offerings and associated capabilities to provide extensions and enhancements to complement and interoperate with existing priority services of the National Communications System: the Government Emergency Telecommunications service for wireline telephone services; and the Wireless Priority Service for wireless cellular telephone service. These services provide priority telephone services for federal, state, local, and tribal leadership and key industry personnel during national security and emergency events. DHS seeks information on other network interfaces such as cable, Voice over Internet Protocol, how priority services and authentication could be provided on data networks that are not using Core VoIP industry requirements, packet based technology and future wireless networks.
