   meets the requirements for transmission by a Participating Commercial
   Mobile Service Provider under this part.

   (b) Common Alerting Protocol. The Common Alerting Protocol (CAP) refers
   to Organization for the Advancement of Structured Information Standards
   (OASIS) Standard CAP-V1.1, October 2005 (available at, or any subsequent
   version of CAP adopted by OASIS and implemented by the WEA.

   (d) Commercial Mobile Service Provider. A Commercial Mobile Service
   Provider (or CMS Provider) is an FCC licensee providing commercial
   mobile service as defined in section 332(d)(1) of the Communications
   Act of 1934 (47 U.S.C. 332(d)(1)). Section 332(d)(1) defines the term
   commercial mobile service as any mobile service (as defined in 47
   U.S.C. 153) that is provided for profit and makes interconnected
   service available to the public or to such classes of eligible users as

   (e) County and County Equivalent. The terms County and County
   Equivalent as used in this part are defined by Federal Information
   Processing Standards (FIPS) 6-4, which provides the names and codes
   that represent the counties and other entities treated as equivalent
   legal and/or statistical subdivisions of the 50 States, the District of
   Columbia, and the possessions and freely associated areas of the United
   States. Counties are considered to be the “first-order subdivisions” of
   each State and statistically equivalent entity, regardless of their
   local designations (county, parish, borough, etc.). Thus, the following
   entities are considered to be equivalent to counties for legal and/or
   statistical purposes: The parishes of Louisiana; the boroughs and
   census areas of Alaska; the District of Columbia; the independent
   cities of Maryland, Missouri, Nevada, and Virginia; that part of
   Yellowstone National Park in Montana; and various entities in the

   associated with the authentication, management and dissemination of WEA
   Alert Messages received from the Alert Gateway.

   (i) CMS provider infrastructure. The mechanism(s) that distribute
   received WEA Alert Messages throughout the CMS provider's network,
