`
`Foreword
`
`This European Standard (Telecommunications series) has been produced by ETSI Special Mobile Group (SMG).
`
`In analogy with CCITT Recommendations 1.130, the first stage of the following three level structure is used to describe
`the telecommunications services as provided by European public telecommunications operators:
`
`Stage 1
`
`Stage 2
`
`Stage 3
`
`is an overall service description, from the service subscriber's and user's standpoint;
`
`identifies the functional capabilities and information flows needed to support the service described
`in stage 1; and
`
`defines the signalling system protocols and switching functions needed to implement the service
`described in stage 1.
`
`This EN details the stage 1 aspects (overall service description) for the General Packet Radio Service (GPRS) on Global
`System for Mobile communications (GSM) networks.
`
`The contents of this EN are subject to continuing work within SMG and may change following formal SMG approval.
`Should SMG modify the contents of this EN it will then be re-submitted for OAP with an identifying change of release
`date and an increase in version number as follows:
`
`Version 6.x.y
`
`where:
`
`indicates GSM Release 1997 of Phase 2+
`
`the second digit is incremented for all other types of changes, i.e. technical enhancements, corrections,
`updates, etc.
`
`the third digit is incremented when editorial only changes have been incorporated in the specification;

`
`Scope
`
`This EN defines the stage one description of the General Packet Radio Service (GPRS) on Global System for Mobile
`communications (GSM) networks. Stage one is an overall service description, primarily from the service subscriber's
`and user's points of view, but does not deal with the details of the human interface itself. This EN includes information
`applicable to network operators, service providers and temiinal, switch and data base manufacturers.
`
`This EN contains the core requirements for the GPRS on GSM, which are sufficient to provide a complete service.
`
`This EN also documents some additional requirements which may be implemented (but do not have to be implemented).
`
`In addition, additional functionalities not documented in this EN may be implemented. The requirements of which are
`considered outside the scope of this EN and consequently outside the scope of the corresponding stage 2 and stage 3
`specifications. This additional functionality may be on a network-wide basis, or particular to one or a group of users.
`Such additional functionality shall not compromise conformance to the core requirements of the service.
`
`The interface between the Mobile Station (MS) and any external applications are outside the scope of this EN.
`
`Charging principles are outside the scope of this EN, unless specific service requirements are stated. These requirements
`deal with the allocation of certain call charges to particular users.
`
`A later phase of GPRS may include interworking with circuit switched networks (e.g. PS'l'N, ISDN) and may emulate
`certain circuit switched services. These aspects are outside the scope of this version of this EN.
`
`NOTE:
`
`This specification includes requirements for GPRS phase 1 (Rel ’97). The first phase of standards
`specified will provide a basic functional GPRS service.
`
`Phase l GPRS supports:
`
`-
`
`PTP
`
`- User Interworking for PTP TC P/IP.
`
`- X28 from MS to GGSN; X.25 from GGSN to external PDNs.
`
`lntemal Network Interfaces:
`
`Gn - GSN backbone network
`
`Gb - BSS to SGSN
`
`Gr - SGSN to llLR
`
`Gp - PLMN to PLMN (ie roaming)
`
`Gs - SGSN to MSC
`
`External Reference point Gi for connecting via TCP/IP and X.25

`and a network to enable the user to employ the services and/or facilities of that network (source: 1TU-T 1.112).
`
`accuracy: A performance criterion that describes the degree of correctness with which a function is performed. (The
`function may or may not be performed with the desired speed.) (source: ITU-T 1.350).
`
`B b
`
`asic service: The teleconmlunication services excluding the supplementary services (source: GSM 01.04).
`
`bearer service: A type oftelecommunication service that provides the capability for the transmission of signals between
`user-network interfaces (source: GSM 01.04, 1TU-T 1.112).
`
`best effort service: A service model which provides minimal performance guarantees, allowing an unspecified variance
`in the measured performance criteria.
`
`C c
`
`alling user: Entity which originates a call to the General Packet Radio Service (GPRS).
`
`connectionless service: A service which allows the transfer of information among service users without the need for
`end-to-end call establishment procedures (source: 1TU-T 1.113).
`
`connectionless-mode transfer:
`
`ZTE Corporation and ZTE (USA) Inc.
`
`Exhibit 1005.01-00008
`
`

`
`GSM 02.60 version 6.1.1 Release 1997
`
`EN 301 113 V6.1.1 (1998-11)
`
`"The terms ‘message’, 'datagram', ‘transaction mode‘ and ‘connection-free’ l1ave been used in the literature to
`describe variations on the same basic theme: the transmission ofa unit ofdata in a single, self-contained
`operation without establishing, maintaining, and releasing a connection.”
`
`"(Connectionless-mode transmission) is the transmission ofa single unit of data from a source service-access-
`point to one or more destination service-access-point(s) without establishing a connection. A connectionless-
`mode service allows an entity to initiate such a transmission by the performance of a single service access.
`
`In contrast to a connection, an instance of the use of a connectionless-mode service does not have a clearly
`distinguishable lifetime. In addition, the connectionless-mode service, unless otherwise explicitly determined, has
`the following fundamental characteristics:
`
`a) no dynamic peer-to-peer agreement is involved in an instance of the service;
`
`b) all of the information required to deliver a unit of data (destination address, quality of service selection,
`options, etc.) is presented to the layer providing the connectionless-mode service, together with the user data
`to be transmitted, in a single service access. The layer providing the connectionless-mode service is not
`required to relate this access to any other service access.
`
`As a result of these fundamental characteristics it may also be true that
`
`each unit of data transmitted is entirely self-contained and can be routed independently;
`
`copies of a unit of data can be transmitted to a number of destination addresses."
`
`NOTE: Connectionless-mode transfer normally implies that the service a) does not provide confirmed
`delivery of SDUs, b) does not guarantee delivery of SDUS, e) does not guarantee maintenance of SDU
`sequencing and d) does not guarantee elimination of SDUs.
`
`connection-mode transfer:
`
`"A connection is an association established for the transfer of data between two or more peer-entities. This
`association is established between the peer-entities themselves and between each entity and the next lower layer.
`The ability to establish a connection and to transfer data over it is provided to the entities in a given layer by the
`next lower layer as a co11nectio11-mode service. An instance of the use of a com1ectio11-mode service by peer-
`entities proceeds through three distinct phases of operation:
`
`a) connection establishment;
`
`b) data transfer; and
`
`c) connection release."
`
`NOTE:
`
`Connection-mode transfer normally implies that the service a) provides confirmed delivery of SDUs, b)
`provides ordered, in-sequence delivery of SDUS and e) will not duplicate SDUs.
`
`conversational service: An interactive service which provides for bi-directional communication by means of real-time
`(no store-and-forward) end-to-end information transfer from user to user (source: ITU-T 1.113).
`
`D d
`
`emand service: A type of telecommunication service in which the communication path is established almost
`immediately, in response to a user request effected by means of user-network signalling (source: GSM 01.04, ITU-T
`1.1 12).
`
`dependability: A performance criterion that describes the degree of certainty (or surety) with which a function is
`performed regardless of speed or accuracy, but within a given observational interval (source: ITU-T 1.350).
`
`destination user: Entity to which calls to the General Packet Radio Service (GPRS) are directed.
`
`E e
`
`xtra 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: l'l'U-'l' X.l40).

`
`mobile termination: The part ofthe mobile station which terminates the radio transmission to and from the network and
`adapts terminal equipment capabilities to those of the radio transmission (source GSM 01.04).
`
`N n
`
`etwork connection: An association established by a network layer between two users for the transfer of data, which
`provides explicit identification of a set of network data transmissions and agreement concerning the services to be
`provided by the set (source: 1TU-T X.213 / 1S0-1l:‘C 8348).
`
`network operator: Entity which provides the network operating elements and resources for the execution of the
`General Packet Radio Service (GPRS).
`
`network service data unit (NSDU): A unit of data passed between the user and the GPRS network across a Network
`Service Access Point (NSAP).
`
`network termination: A functional group on the network side of a user-network interface (source: lTU-T 1.112).
`
`P p
`
`acket: An information unit identified by a label at layer 3 of the OSl reference model (source: lTU-T 1.113). A
`network protocol data unit (NPDU).
`
`packet data protocol (PDP): Any protocol which transmits data as discrete units known as packets, e.g., IP, or X.25.
`
`packet transfer mode: Also known as packet mode. A transfer mode in which the transmission and switching functions
`are achieved by packet oriented techniques, so as to dynamically share network transmission and switching resources
`between a multiplicity of connections (source: 1TU-T 1.113).

`
`peak bit rate: A measure of throughput. The maximum bit rate offered to the user for a given time period (to be
`defined) for the transfer of a bursty signal (source: ITU-T 1.210). (The maximum user information transfer rate
`achievable by a user for a single service data unit transfer.)
`
`PLMN Operator: Public Land Mobile Network operator. The entity which offers a GPRS.
`
`point-to-point (PTP): A value of the service attribute "communication configuration", which denotes that the
`communication involves only two network terminations.
`
`point-to-point (PTP) service: A service type in which data is sent from a single network termination to another network
`termination.
`
`predictive service: A service model which provides reliable performance, but allowing a specified variance in the
`measured perfomrance criteria.
`
`protocol: A fomlal set of procedures that are adopted to ensure communication between two or more functions within
`the within the same layer ofa hierarchy of functions (source: l'l'U-T 1.1 l 2).
`
`protocol data unit (PDU): In the reference model for OS1, a unit of data specified in an (N)-protocol layer and
`consisting of (N)-protocol control infomration and possibly (N)-user data (source: ITU-T X.200 / ISO-IEC 7498-1).
`
`Q q
`
`uality of service: The collective effect of service perfomlances which (lCtCI‘I11i11C the degree of satisfaction of a user of
`the service (ITU-'1' E800). The set ofperformance parameters that can be directly observed and measured at the point at
`which the service is accessed by the user. There are three criteria by which performance is measured: speed, accuracy
`and dependability (source: ITU-T 1.350).
`
`R r
`
`eference configuration: A combination of functional groups and reference points that shows possible network
`arrangements (source: GSM 01.04. l'l'U-'l' 1.1 12).
`
`reference point: A conceptual point at the conjunction of two non-overlapping functional groups (source: GSM 01.04,
`ITU-T 1.112).
`
`residual error rate: A parameter describing service accuracy. The frequency of lost SDUS, and ofcorrupted or
`duplicated network SDUs delivered at the user-network interface.
`
`retrieval service: An interactive service which provides the capability of accessing information stored in data base
`centres. The information will be sent to the user on demand only. The information is retrieved on an individual basis,
`i.e., the time at which an information sequence is to start is under the control of the user (source ITU-T 1.113).
`
`S S
`
`DU error probability: The ratio of total incorrect service data units (SDUs) to total successfully transferred service
`data units plus incorrect service data units in a specified sample (source: l'l'U-’l' X.l 40).
`
`NOTE:
`
`the source document term "user information unit" has been replaced by the term "service data unit".
`
`SDU loss probability: The ratio of total lost service data units (SDUs) to total transmitted service data units in a
`specified sample (source: ITU-T X.140).

`
`the source document term "user information unit" has been replaced by the term "service data unit".
`
`SDU misdelivery probability: The ratio of total misdelivered service data units (SDUs) to total service data units
`transferred between a specified source and destination user in a specified sample (source: l'l'U-'l’ X.l40).
`
`NOTE:
`
`the source document term "user information unit" has been replaced by the term "service data unit".
`
`SDU transfer delay: The value of elapsed time between the start of transfer and successful transfer of a specified
`service data unit (SDU) (source: ITU-T X.140).
