Starting from an overview of the MAMES objectives and operations, the MAMES Architecture is presented:
35、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 MAME
36、S 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. 2 References 2.1 Normative references Refe

48、 entity that generates Alert Messages and forwards them to a MAMES Alert Provider for MAMES Encapsulation; more generally, entity that terminates an Alert Protocol at the alerter side of an Alert Network NOTE: Depending on the Alert Protocol used, an Alert Issuer may be capable of updating or cancel
49、ling a previously issued Alert Message, and of requesting and accepting acknowledgement messages. Alert Message: Alert Protocol Message containing data to alert and/or inform Alert Users about an impending or on-going emergency ETSI ETSI TS 103 337 V1.1.1 (2015-05)10 Alert Network: in the context of the present document, telecommunications or navigation network that supports Alert Protocol Messages Alert Protocol: protocol used to exchange Alert Protocol Messages NOTE 1: In its most basic form, an Alert Protocol is a simple, mutually agreed rul
