Application Detection and Control
Policy rules that enable detection and control of application traffic and associated enforcement action.
Access Point Name
The name identifying a general packet radio service (GPRS) bearer service in a GSM mobile network. See also GSM.
Allocation and Retention Priority
A mechanism to downgrade lower-priority bearers, or upgrade higher-priority bearers, in cases of network congestion or emergency. Used when a service or bearer is admitted, allocated, or handed over.
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.
Basic Service Set Identifier
MAC address of the wireless access point.
Diameter Edge Agent
Device through which LTE roaming signaling traffic is funneled to protect network element addresses from being exposed to third parties.
Evolved Packet System
EPS is the core or main component of an LTE (Long-Term Evolution) system.
Fully Qualified Domain Name
The complete domain name for a specific computer on the Internet (for example, www.oracle.com).
A domain name that specifies its exact location in the tree hierarchy of the DNS.
Guaranteed Bit Rate
A minimum bit rate requested by an application for uplink and downlink traffic.
Long Term Evolution
The next-generation network beyond 3G. In addition to enabling fixed to mobile migrations of Internet applications such as Voice over IP (VoIP), video streaming, music downloading, mobile TV, and many others, LTE networks will also provide the capacity to support an explosion in demand for connectivity from a new generation of consumer devices tailored to those new mobile applications.
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.
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.
Policy and Charging Control
Policy rules that define the conditions and actions used by a carrier network to control how subscribers and applications are treated and how network resources are allocated and used.
Policy and charging enforcement function
A system responsible for enforcing policies on network subscriber authentication, authorization, accounting, and mobility. A PCEF device, such as a CMTS or GGSN, communicates with a PCRF device, such as a policy server.
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).
Quality of Service
Control mechanisms that guarantee a certain level of performance to a data flow.
Remote Authentication Dial-In User Service
A client/server protocol and associated software that enables remote access servers to communicate with a central server to authorize their access to the requested service. The MPE device functions with RADIUS servers to authenticate messages received from remote gateways. See also Diameter.
Session Initiation Protocol
A peer-to-peer protocol used for voice and video communications.
Short Message Peer-to-Peer Protocol
An open, industry standard protocol that provides a flexible data communications interface for transfer of short message data.
Short Message Service
A communication service component of the GSM mobile communication system that uses standard communications protocols to exchange short text messages between mobile phone devices. See also GSM.
Shared Metric Service
Subscriber Profile Repository
A logical entity that may be a standalone database or integrated into an existing subscriber database such as a Home Subscriber Server (HSS). It includes information such as entitlements, rate plans, and so on.The PCRF and SPR functionality is provided through an ecosystem of partnerships.
Service Set Identifier
Used to uniquely identify a wireless LAN.
eXtensible Markup Language
A version of the Standard Generalized Markup Language (SGML) that allows Web developers to create customized tags for additional functionality.
