See Section 2.1.2 for the definition of the Reference Points associated with each Network Entity. Authentication, Authorization and Accounting (AAA) The AAA is an entity that provides Internet Protocol functionality to support the functions of Authentication, Authorization and Accounting. Authentication Center (AC) The AC is an entity that manages the authentication information related to the MS. The AC may, or may not be located within, and be indistinguishable from an HLR. An AC may serve more than one HLR. Base Station (BS) A BS is an entity that provides the means for MSs to access network services using radio. It includes a BSC and a BTS.
