7、SM 02.02 Version 5.1 .O: May 1996 Foreword This Global System for Mobile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This GTS defines a set of bearer services
8、to be provided within the digital cellular telecommunications system (Phase 2/Phase 2+). This GTS is a TC-SMG approved GSM technical specification version 5, which contains GSM Phase 2+ enhancementdfeatures to the version 4 GSM technical specification. The ETS on which this Phase 2+ GTS is based is
9、Phase 2 GSM ETS 300 501 (GSM 02.02 version 4.2.2). GTS are produced by TC-SMG to enable the GSM Phase 2 + specifications to become publicly available, prior to submission for the formal ETSI standards approval procedure to become European Telecommunications Standards (ETS). This ensures the earliest
10、 possible access to GSM Phase 2 + specifications for all Manufacturers, Network operators and implementors of the Global System for Mobile communications. The contents of this GTS are subject to continuing work within TC-SMG and may change following formal TC-SMG approval. Should TC-SMG modify the c
11、ontents of this GTS it will then be republished by ETSI with an identifying change of release date and an increase in version number as follows: Version 5.x.y where: y the third digit is incremented when editorial only changes have been incorporated in the specification; x the second digit is increm
12、ented for all other types of changes, .e. technical enhancements, corrections, updates, etc. The specification from which this GTS has been derived was originally based on CEPT documentation, hence the presentation of this GTS may not be entirely in accordance with the ETSI rules. Reference is made
13、within this TS to GSM-TSs (note). NOTE: TC-SMG has produced documents which give the technical specifications for the implementation of the digital cellular telecommunications system. Historically, these documents have been identified as GSM Technical Specifications (GSM-TSs). These TSs may have sub
14、sequently become I-ETSs (Phase I), or ETSs/ETSI Technical Reports (ETRs) (Phase 2). TC-SMG has also produced ETSI GSM TSs which give the technical specifications for the implementation of Phase 2+ enhancements of the digital cellular telecommunications system. These version 5.x.x GSM Technical Speci
15、fications may be referred to as GTSs.

16、e provided to GSM PLMN subscribers by a GSM PLMN itself and in connection with other networks. This specification should also be used as a reference for defining the corresponding required mobile network capabilities which are specified by means of the “GSM PLMN connection type“ concept, defined in
17、GSM 03.10. The recommended provision of the bearer services is under the control of the GSM MOU and is out of the scope of ETSI TC-SMG. Bearer services not included in this specification that require modifications to the GSM signalling specifications should not be introduced unilaterally by a mobile
18、 network operator. o. 1 Normative references This GTS incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to

These attributes are described and defined in GSM 02.01. They are g
32、rouped into four categories: i) Information transfer attributes, which characterise the network capabilities for transferring information from a user access point in a GSM PLMN to a user access point in another network. (Refer to GSM 02.01 and 04.02 for definitions of user access points, originating
33、 and terminating networks.) i) Access attributes, which describe the means for accessing network functions or facilities as seen at the access point in the PLMN (see GSM 02.01). iii) Interworking attributes, which describe properties of the terminating network and its access point. The terminating n
34、etwork may include another GSM PLMN or the originating PLMN (see GSM 02.01). iv) General attributes, which deal with the service in general. Figure I/GSM 02.02 shows the relation between the groups of attributes and their fields of applicability. 3 ETSI GSM*02.02 9b = 3400855 0105548 786 Page 9 GSM
35、02.02 Version 5.1 .O: May 1996 Information Transfer and Access Attributes (Note 3) i - -+ I General Attributes (NOTE 2) NOTE 1 : A transit network may not exist for a bearer service. NOTE 2: Communication may be established from either end. NOTE 3: The information transfer and access attributes of a
36、 bearer service relate to a direct peer-to-peer communication of: - TE tTE, - TE to a network gateway (supporting,for example, PSTN interworking), or - network gateway to a TE. Figure l/GSM 02.02: Relation between the groups of attributes and fields of applicability The following table lists the ind
37、ividual attributes in each of the four groups. The GSM bearer service definitions in this specification are based on the “Minimal Set“ of attributes.

40、define the use of each bearer service. See the GSM 07-series specifications for information about the Signalling Access Protocols, Information Access Protocols and related access attributes. GSM supplementary services are defined in GSM 02.04. Intercommunication is required with services in the PSTN
41、, ISDN, CSPDN and other PLMNs. The capabilities that describe the Interworking Attributes are described in GSM 03.10 and the GSM 09-series specifications. 2 Bearer service categories All bearer service categories provide information transfer between R/S reference points and allow the use of sub-rate
42、 information streams which are rate-adapted. The bearer services can be grouped into the following categories: - Unrestricted Digital Information (UDI); Provides the transfer of unrestricted digital information. - 3.1 kHz (External to the PLMN); Used to select a “3.1 kHz audio“ interworking function
43、 at the MSC. This service category is used when interworking with the ISDN or PSTN “3.1 kHr audio“ service and includes the capability to select a modem at the interworking function. “External to the PLMN“ indicates that the “3.1 kHz audio“ service is only used outside of the PLMN, in the ISDN/PSTN.
44、 The connection within the PLMN, user access point to the interworking function, is an unrestricted digital connection. PAD; Provides an asynchronous connection to a PAD. This enables PLMN subscribers to access a packet network (PSPDN/ISDN). See GSM TS 09.05 for service and interworking specificatio
45、ns. ETSI GSM*02.02 b 3480855 0305550 334 Page 11 GSM 02.02 Version 5.1 .O: May 1996 Provides a synchronous connection that enables PLMN subscribers to access a packet network (PSPDNISDN). See GSM TS 09.06 for service and interworking specifications. - Packet; - - Alternate Speech/Data; Provides the
46、capability to swap between speech and data during a call. BSS - MSC 1F Mobile Station If either the speech or data portion of the call requires a full rate channel, a full rate channel shall be used for the duration of the call. The access interface at the mobile station for the data portion is assu
47、med to be a standard data interface. Some means must be provided to select the speech/data capability. - Speech followed by Data; Provides a speech connection first and then at some time while the call is in progress, the user can switch to a data connection. The user cannot switch back to speech af
48、ter the data portion. If either the speech or data portion of the call requires a full rate channel, a full rate channel shall be used from the start of the call. The network may then change to a half rate channel for the data portion. 3 Bearer services This section provides a list of the existing G
49、SM bearer services and indicates the values for each attribute in the minimal set. The following attributes have the same value for all GSM bearer services. Their values are as follows: Information Transfer Mode: “Circuit“ Information Transfer Rate: Establishment of Communication: “Demand“ Symmetry: “Bi-directional Symmetric“ (NOTE 2) Communication Configuration: “Point to point“ Not applicable (NOTE 1) NOTE 1: The Information Transfer Rate attribute is not applicable because it depends on the reference point assumed in the GSM PLMN, transit or terminating network.
