An enterprise messaging system (EMS) or messaging system in brief [1] is a set of published enterprise-wide standards that allows organizations to send semantically precise messages between computer systems. EMS systems promote loosely coupled architectures that allow changes in the formats of messages to have minimum impact on message subscribers.
Southbound, the EMS talks to the devices. An element management system manages one or more of a specific type of telecommunications network element. Typically, the EMS manages the functions and capabilities within each NE but does not manage the traffic between different NEs in the network.
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
The Master Street Address Guide (MSAG) is a database of street addresses and corresponding Emergency Service Numbers (ESNs). [7] ESNs represent one or more emergency service agencies (e.g. fire department, law enforcement) designated to serve a specific range of addresses in a geographic area, called an Emergency Service Zone.
The protocols are codified in a series of ETSI Technical Specifications. Many services can be created using CAMEL, and it is particularly effective in allowing these services to be offered when a subscriber is roaming , like, for instance, No-prefix dialing (the number the user dials is the same no matter the country where the call is placed ...
With this technology, emergency communications will "pop up" on the personal computer screens as a new window that sits on top of any other window that may be open on the screen at the time. This technology uses LAN and/or WAN networks to deliver short messages, often less than about 120 characters in length, typically in real time.
He designed a set of standardized protocols to triage patients via the telephone and thus improve the emergency response system. Protocols were first alphabetized by chief complaint that included key questions to ask the caller, pre-arrival instructions, and dispatch priorities. After many revisions, these simple cards have evolved into MPDS.
Enhanced Messaging Service (EMS) was a cross-industry collaboration between magic4, Ericsson, Motorola, Siemens and Alcatel among others, which provided an application-level extension to Short Message Service (SMS) for cellular phones available on GSM, TDMA and CDMA networks.
