The present document specifies the functions needed for terminal adaptation within the 3GPP system. The con
39、tents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as foll
40、ows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc.
41、 z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 127 001 V15.0.0 (2018-07)73GPP TS 27.001 version 15.0.0 Release 151 Scope The present document is based on the principles of terminal adaptor functions presented in the ITU-T I-series o
42、f Recommendations (I.460 to I.463). The PLMN supports a wide range of voice and non-voice services in the same network. In order to enable non-voice traffic in the PLMN there is a need to connect various kinds of terminal equipment to the Mobile Termination (MT). The target of the present document i
43、s to outline the functions needed for the terminal adaptation. The bearer services are described in 3GPP TS 22.002 and the general network configuration is described in 3GPP TS 23.002. The PLMN access reference configuration is defined in 3GPP TS 24.002. The various connection types used in the A/Gb
44、 mode or GERAN Iu mode PLMN are presented in 3GPP TS 43.010. Terminology used in the present document is presented in 3GPP TR 21.905 and 3GPP TS 29.990. For support of data services between a PLMN and other networks see 3GPP TS 29.007. The present document is valid for a 2ndgeneration PLMN (A/Gb mod
45、e) as well as for a 3rdgeneration PLMN (Iu mode). If text applies only for one of these systems it is explicitly mentioned by using the terms “A/Gb mode“ and “UTRAN Iu mode“. If text applies to both of the systems, but a distinction between the ISDN/PSTN and the PLMN is necessary, the term “PLMN“ is
46、 used. NOTE 1: From R99 onwards the following services are no longer required by a PLMN: - the dual Bearer Services “alternate speech/data“ and “speech followed by data“; - the dedicated services for PAD and Packet access; - BS 21 . 26 and BS 31 . 34. From REL-4 onwards the following service is no l
47、onger required by a PLMN: - the synchronous Bearer Service non-transparent (BS 30 NT). - non-transparent facsimile (TS 61/62 NT) for the A/Gb mode and GERAN Iu mode. The support of these services is still optional. The specification of these services is not within the scope of the present document.
48、For that, the reader is referred to former releases. NOTE2 : The Gb interface does not play any role in the scope of the present document although the term “A/Gb mode“ is used. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the
49、 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 of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 Void. 2 3GPP TS 22.002: “Circuit Bearer Services (BS) supported by a Public Land Mobile Network (PLMN)“. 3
