1 Scope
The present document establishes the specifications for the MAMES (Multiple Alert Message Encapsulation over
Satellite) Protocol. Starting from an overview of the MAMES objectives and operations, the MAMES Architecture is
presented: the MAMES functional entities are identified and the MAMES positioning in a protocol-stack architecture is
provided by defining a set of MAMES operational scenarios.
The MAMES alert message encapsulation scheme is specified by defining the overall MAMES Message structure, the
different types of MAMES messages and all MAMES Header fields.
The behaviour of the MAMES Agents responsible for the process of the MAMES Protocol is defined.
Guidelines for integrating the MAMES alert message encapsulation scheme into communications networks are
provided in [i.1].
