|---|---|
| AIR/A | Authentication-Information Request/Answer |
| ART | Application Routing Table |
| AVP |
Attribute-Value Pair The Diameter protocol consists of a header followed by one or more attribute-value pairs (AVPs). An AVP includes a header and is used to encapsulate protocol-specific data (for example, routing information) as well as authentication, authorization or accounting information. |

| DCA | Diameter Custom Application |
| DRA | Diameter Relay Agent |
| DRL |
Diameter Routing Layer The software layer of the stack that implements Diameter routing. |
| DSA | Diameter Security Application |
| DSR |
Diameter Signaling Router A set of co-located Message Processors which share common Diameter routing tables and are supported by a pair of OAM servers. A DSR Network Element may consist of one or more Diameter nodes. |
| DSR/A | Delete-Subscriber-Data Request/Answer |
| FQDN |
Fully Qualified Domain Name The complete domain name for a specific computer on the Internet (for example, http://www.oracle.com). A domain name that specifies its exact location in the tree hierarchy of the DNS. |

Graphical User Interface The term given to that set of items and facilities which provides you with a graphic means for manipulating screen data rather than being limited to character based commands. |
| HSS |
Home Subscriber Server A central database for subscriber information. |
| IDA | Insert-Subscriber-Data Request |
| IDR | Insert-Subscriber-Data Answer |
| IMSI |
International Mobile Subscriber Identity A unique internal network ID identifying a mobile subscriber. |
| IP |
Internet Protocol IP specifies the format of packets, also called datagrams, and the addressing scheme. The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. It provides packet routing, fragmentation and re-assembly through the data link layer. |
| IPX | IP exchange |
| KPI | Key Performance Indicator |
| LTE | Long-Term Evolution |
| MAP |
Mobile Application Part An application part in SS7 signaling for mobile communications systems. |
| MCC |
Mobile Country Code A three-digit number that uniquely identifies a country served by wireless telephone networks. The MCC is part of the International Mobile Subscriber Identity (IMSI) number, which uniquely identifies a particular subscriber. See also MNC, IMSI. |
| MEAL | Measurements, Events, Alarms, and Logs |
| MNC |
Mobile Network Code A number that identifies a mobile phone carrier. Used in combination with a Mobile Country Code (MCC) to uniquely identify a mobile phone operator/carrier. See also MCC. |
| MNO | Mobile Network Operator |
|
MP |
Message Processor The role of the Message Processor is to provide the application messaging protocol interfaces and processing. However, these servers also have OAM components. All Message Processors replicate from their Signaling OAM's database and generate faults to a Fault Management System. |
| NOAMP | Network Operations, Administration, Maintenance, and Provisioning |
| NOR/A | Notify Request/Answer |
| PLMN |
Public Land Mobile Network A wireless communications network that uses land-based radio transmitters or base stations, intended for public use by terrestrial subscribers in vehicles or on foot. A PLMN is identified by its Mobile Country Code (MCC) and Mobile Network Code (MNC). |
| PRT | Peer Route Table or Peer Routing Table |
| PUR/A | Purge-UE Request/Answer |
| RSR/A | Reset-Subscriber Request/Answer |
| SIVC | Session Integrity Validation Check |
| SOAM | System Operations, Administration, and Maintenance |
| SS7 |
Signaling System #7 A communications protocol that allows signaling points in a network to send messages to each other so that voice and data connections can be set up between these signaling points. These messages are sent over its own network and not over the revenue producing voice and data paths. The EAGLE is an STP, which is a device that routes these messages through the network. |
| ULR/A | Update-Location Request/Answer |
| VPLMN |
Visited Public Land Mobile Network The PLMN to which a mobile subscriber has roamed when leaving the subscriber’s Home Public Land Mobile Network. |
| UDR | Unified Data Repository |
| U-SBR | Universal Session Binding Repository |
