`
`Scope
`
`The purpose ofthis report is to identify specialist technical terms used within the 3GPP project for the purposes of
`specifying service requirements. The motivations for this are:
`
`- To ensure that editors use terminology that is consistent across specifications.
`
`-
`
`—
`
`To provide a reader with convenient reference for technical terms that are used across multiple documents.
`
`To prevent inconsistent use of terminology across documents.
`
`This document is a collection of terms, definitions and abbreviations related to the baseline documents defining 3GPP
`objectives and systems framework. This document provides a tool for further work on BGPP technical documentation
`and facilitates their understanding.
`
`The terms. definitions and abbreviations as given in this document are either imported from existing documentation
`(ETSI, [TU or elsewhere} or newly created by 3GPP experts whenever the need for precise vocabulary was identified.
`

`
`References
`
`The following documents contain provisions which, through reference in this text. constitute provisions ofthe present
`document.
`
`- References are either specific (identified by date of publication, edition number. version number. etc.) or
`non-specific.
`
`For a Specific reference. subsequent revisions do not apply.
`
`For a non-specific reference, the latest version applies. In the case ofa reference to a 3GPP document {including
`a GSM document), a non-specific reference implicitly refers to the latest version of that document in the some

`
`Essential UE Requirement (Conditional): Requirement which has to be implemented under certain Service
`conditions. e.g. AMR codec in UE which supports speech service
`
`Essential UE Requirement (Unconditional): Requirement which has to be implemented in any 3G UE in order to
`exist in and communicate with 3G network (e.g. Chiprate of 3.34Mcps).
`
`Explicit Diversity Gain (:18): The effective gain achieved using diversity techniques.
`
`Extra SDU delivery probability: The ratio of total (unrequested) extra service data units (SDUs] to total service data
`units received by a destination user in a specified sample (source: [TU-T X. I40}.
`
`NOTE:
`
`the term "user information unit" has been replaced by the term "service data unit".
`
`F F
`
`ile: A named and hierarchically-classified data set on the UICC.
`
`File identifier {FlD): The 2-byte name ofa file or a directory on the UICC.
`
`Fixed Network User Rate: The user rate between IWF and the fixed network.
`
`FC (Flow Control): A set of mechanisms used to prevent the network from becoming overloaded by regulating the
`input rate transmissions.
`
`Flexible Layer One (FLO): GERAN feature that allows the channel coding ofthe layer one to be configured at call
`setup.
`
`Framework: A framework defines a set of Application Programming interface (API) classes for developing
`applications and for providing system services to those applications.
`
`Functional group: A set of functions that may be performed by a single equipment (source: ITU-T L1 12).
`
`G G
`
`eographical routing: The conversion of the PDU"-s geographical area definition. which specifies the area in which
`the PDU will be broadcast, into an equivalent radio coverage map.
`
`GERAN Radio Network Temporary Identifier (G-RNTI): G-RNTI is an MS identifier which is allocated by the
`Serving BSC and is unique within this SBSC. It is allocated for all MSS having an RRC connection. The G-RNTI is
`always reallocated when the Serving BSC for the RRC connection is changed and deallocated when the RRC
`connection is released. The Ci-RNTI is also used at RLCIMAC during contention resolution.
`
`GPRS MS: An MS capable ofGPRS services is a GPRS MS.
`
`Group: A set ofmembers allowed to participate in the group call service. The group is defined by a set of rules that
`identifies a collection of members implicitly or explicitly. These rules may associate members for the purpose of
`participating in a group call, or may associate members who do not participate in data transfer but do participate in
`management, security. control, or accounting for the group.
`
`Group call: The relationship that exists between the members of a group for the purpose of transferring data. More than
`one group call may exist in a group. A group call establishes an active group.
`
`Group call initiator: A member [or third party) authorised to initiate a group call. More than one member may initiate
`group calls.
`
`Group call participant: A member of a group participating in a particular group call at a given time.
`
`Group call server: A logical entity that provides the group call service to the members.
`
`Group call service: A PTM service in which a relationship exists between participants of the group, and in which a
`single data unit transmitted by a source participant is received by multiple destination participants; it is a one-in, many-
`out service.
`
`Grup controller: The member (or third party) responsible for the group creation and membership control.

`
`GSM.-‘EDGE Radio Access Network: GERAN is a conceptual temt identifying that part of the network which consists
`of BSCs and BTSs between AIGIJ or In and Urn interfaces.
`
`GSM BSS: refers in this specification to the GSWGPRS access network.
`
`GSM core network: refers in this specification to the GSM NSS and GPRS backbone infrastructure.
`
`GSM coverage: an area where mobile cellular services are provided in accordance with GSM standards
`
`GSM session: That part of the card session dedicated to the GSM operation.
`
`Guaranteed service: A service model which provides highly reliable performance, with little or no variance in the
`measured performance criteria.
`
`H H
`
`andoff GaintLoss (dB): This is the gainfloss factor (+ or -) brought by handoff to maintain specified reliability at the
`cell boundary.
`
`Handover: The transfer of a user"s connection from one radio channel to another (can be the same or different cell).
`
`Handover: The process in which the radio access network changes the radio transmitters or radio access mode or radio
`system used to provide the bearer services. while maintaining a defined bearer service QoS.
`
`Hard Handover: Hard handover is a category of handover procedures where all the old radio links in the UE are
`abandoned before the new radio links are established.
`
`HE-VASP: Home Environment Value Added Service Provider. This is a VASP that has an agreement with the Home
`Environment to provide services. The Home Environment provides services to the user in a managed way, possibly by
`collaborating with l-iE~VASPs, but this is transparent to the user. The same service could be provided by more than one
`HE-VASP and each HE—VASP can provide more than one service.
`
`Home Environment: responsible for overall provision and control of the Personal Service Environment of its
`subscribers.
`
`Home PLMN: PLMN where the Mobile Country Code (MCC) and Mobile Network Code (MNC) ofthe PLMN
`identity are the same as the MCC and MNC ofthe {MS}.
`
`IC Card: A card holding an integrated Circuit containing subscriber, end user, authentication andlor application data
`for one or more applications.
`
`IC card SIM: Obsolete term for ID-l SIM.
`
`ICS proforma: A document, in the form of a questionnaire, which when completed for an implementation or system
`becomes an ICS.
