The scope of this document covers support for Commercial Mobile Alert t Service (CMAS). The network entities and associated reference points that comprise the CMAS Reference Architecture for CDMA are included. The reference architecture, as defined herein, is intended to provide a level of abstraction that may facilitate the specification of messages and protocols within. As such, implementations may vary with respect to how the functional entities are distributed among various physical units. In cases where functional entities are combined in the same physical equipment, the reference points between those entities become internal, and need not adhere to interface standards.
