Authorized QoS is the maximum QoS that is authorized by PCRF. Three types of authorized QoS are identified over Gx reference point: QoS per IP-CAN Bearer, QoS per QCI and QoS per PCC rule. For QoS per IP-CAN Bearer, it applies to all service data flows with an IP-CAN Bearer. For QoS per QCI, it is similar to QoS per IP-CAN Bearer, while it is used with PCEF-Based bearer binding. For QoS per PCC rule, it applies to service data flow matching the rule.

: Bearer Binding Mechanism refers to the method for creating, modifying and deleting bearer bindings. It can be classified into two types: PCRF-based bearer binding and PCEF-Based bearer binding. For PCRF-Based bearer binding, the association between SDF and IP-CAN bearer is determined solely by PCRF. For PCEF-Based bearer binding, SDF is associated with IP-CAN bearer mainly by PCEF. The output of PCEF-Based bearer binding is recognized as the input of NRSPCA procedure.

 CAGR
 Compound annual growth rate
Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from different data sets such as revenue growth of companies in the same industry.

A TX/RX-point constitutes of a set of co-located TX/RX antennas providing coverage in the same sector. The set of TX/RX-points used in CoMP can either be at different locations, or co-sited but providing coverage in different sectors, they can also belong to the same or different eNBs.

Customer experience (CX) is the sum of all experiences a customer has with a supplier of goods and/or services, over the duration of their relationship with that supplier. This can include awareness, discovery, attraction, interaction, purchase, use, cultivation and advocacy. It can also be used to mean an individual experience over one transaction; the distinction is usually clear in context.

 DPI
 Deep Packet Inspection
DPI is a form of computer network packet filtering that examines the data part (and possibly also the header) of a packet as it passes an inspection point, searching for protocol non-compliance, viruses, spam, intrusions, or defined criteria to decide whether the packet may pass or if it needs to be routed to a different destination, or, for the purpose of collecting statistical information. There are multiple headers for IP packets; network equipment only needs to use the first of these (the IP header) for normal operation, but use of the second header (TCP, UDP etc.) is normally considered to be shallow packet inspection (usually called Stateful Packet Inspection) despite this definition.

DTLS allows datagram-based applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the stream-oriented Transport Layer Security (TLS) protocol and is intended to provide similar security guarantees. The datagram semantics of the underlying transport are preserved by the DTLS protocol

 Evolved Pacekt Core
When designing the evolution of the 3G system, the 3GPP community decided to use IP (Internet Protocol) as the key protocol to transport all services. It was therefore agreed that the EPC would not have a circuit-switched domain anymore and that the EPC should be an evolution of the packet-switched architecture used in GPRS/UMTS. Traditional use of circuits to carry voice and short messages needed to be replaced by IP-based solutions in the long term.

A GTP tunnel in the GTP-C plane is defined for all PDP Contexts with the same PDP address and APN (for Tunnel Management messages and UE Specific MBMS message), for each MBMS service (for Service Specific MBMS messages) or for each MS (for other types of messages). A GTP tunnel is identified in each node with a TEID, an IP address and a UDP port number. A GTP tunnel is necessary to forward packets between an external packet data network and an MS user.

 High Rate Packet Data
A novel method of architecting relay functions, within the paradigm of frequency division duplex based cellular networks, by modifying the Access Terminals (AT) to AT Relays (ATR) and enhancing HRPD Access Networks (AN) is proposed. Traditional applications such as spot/emergency coverage, and new applications related to network auto-configuration, optimization, and fault management are supported. Two bi-directional data streams are supported concurrently within a single AT radio aided by relatively simple enhancements to power and resource allocation mechanisms at the AT/AN, and interference cancellation at the AN to reduce blow-back to the data-sourcing ANs from the forwarding ATRs. A self-routing and self-configuring backhaul capability is created with a new flow type, and by adding a new request-response route-discovery protocol.

 Local Realm
 
A local realm is the administrative domain providing services to a user. An administrative domain MAY act as a local realm for certain users, while being a home realm for others. Multi-session A multi-session represents a logical linking of several sessions. Multi-sessions are tracked by using the Acct-Multi-Session-Id. An example of a multi-session would be a Multi-link PPP bundle. Each leg of the bundle would be a session while the entire bundle would be a multi-session.

 LROAN
 Long-Reach Optical Access Networks
The concept of the Long-Reach Optical Access Network (LROAN) is to replace the optical/electrical/optical conversion that takes place at the local exchange with a continuous optical path that extends from the customer to the core of the network. Work by Davey and Payne at BT showed that significant cost savings could be made by reducing the electronic equipment and real-estate required at the local exchange or wire center.

 MPLS
 Multiprotocol Label Switching
MPLS is a scalable, protocol-independent transport. In an MPLS network, data packets are assigned labels. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. This allows one to create end-to-end circuits across any type of transport medium, using any protocol. The primary benefit is to eliminate dependence on a particular

MPLS-TP?or?MPLS Transport Profile?is a profile of?MPLS?whose definition has been commenced by the?IETF. It will be designed for use as a network layer technology in transport networks. Its design will be a continuation of the work started by the transport network experts of the?ITU-T, specifically SG15, as?T-MPLS. Since 2008 the work is progressed in a cooperation between?ITU-T?and?IETF. The required protocol extensions to MPLS being designed by the IETF based on requirements provided by service providers. It will be a connection-oriented packet-switched (CO-PS) application. It will offer a dedicated MPLS implementation by removing features that are not relevant to CO-PS applications and adding mechanisms that provide support of critical transport functionality.
