▀ Environmental Information
CLCI Server. DCCA server typically located in the Online Charging System.
CDMA. Code Division Multiple Access. One of three wireless technology classes that encompasses 2G, 2.5G, and 3G
communications. The other two are GSM and TDMA.
cdmaOne. Defines the 2G and 2.5G versions of CDMA technology. Based on IS-95A and IS-95B standards
respectively.
CDMA2000. Defines the 3G version of CDMA technology.
CDR. Charging Data Record. A GTPP-based subscriber accounting record. Charging data record (also known as call
detail record) consists of formatted information that includes event-based billing information such as call duration.
Different systems generate different types of CDRs. The types, content and handling of CDRs is defined in various
3GPP specs within the TS 32.2xx series,
Cell. The unit of a base station having the ability to radiate in a given geographic area; a ―sector‖ or ―face‖ of a physical
radio equipment implementation.
CFE. Common Firmware Environment. The system hardware that contains control processor-based software within
the system.
CG. Charging Gateway. The device on the GSM GPRS or UMTS network that collects and maintains Call Detail
Records (CDRs) for subscriber PDP contexts. Also referred to as a Charging Gateway function (CGF).
CGF. See CG.
Charging Rule. A set of information including the service data flow filters (IP 5 tuple), the gating status (pass/drop
packets matching the rule) and the rating group, for a single service data flow. For an IMS media component a charging
rule typically defines a single IP flow associated to a media component (e.g. RTP or RTCP).
CLI. Command Line Interface. A Man-machine Interface (MMI) used to configure, monitor, and administer a network
device through its Operating System (OS).
CSG.. Closed Subscriber Group. A Closed Subscriber Group identifies subscribers of an operator who are permitted to
access one or more cells of the PLMN but which have restricted access (CSG cells).
CSG Cell. A CSG cell, part of the PLMN, broadcasting a specific CSG identity. A CSG cell is accessible by the
members of the closed subscriber group for that CSG identity. All the CSG cells sharing the same CSG identity use the
same radio access technology.
CSG ID. A CSG ID is an identifier associated to a cell or group of cells to which access is restricted to a defined group
of users.
Current EPS security context. the EPS security context which has been taken into use by the network most recently.
Current serving cell. This is the cell on which the MS is camped.
CO. Central Office. The telecommunications facility where calls are switched.
Context. A specific group of configuration parameters that apply to the ports, interfaces, protocols, and services
supported by a system. Each system can support multiple contexts and each context can reside as a separate, logically
independent instance. Multiple context support allows numerous like or disparate services to exist on the same physical
hardware.
CORBA. Common Object Request Broker Architecture. The Object Management Group's (MAG's) core specification
for distributed object interoperability.
Correspondent node. A node that sends or receives a packet to an MN; the correspondent node may be another mobile
node or a non-mobile Internet node.
CP. Control Processor, a high-speed state-of-the-art CPU used by the system.
CSP. Card Slot Port subsystem. This is a software subsystem that manages all cards, slots, and physical ports installed
in a system.
