25、3 146 V15.0.0 (2018-07)53GPP TS 23.146 version 15.0.0 Release 15Foreword This Technical Specification has been produced by the 3rdGeneration Partnership Project (3GPP). The present document defines the technical realization of facsimile group 3 using non-transparent network support within the 3GPP s
26、ystem. The contents 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
27、number as follows: 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,
28、 updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 123 146 V15.0.0 (2018-07)63GPP TS 23.146 version 15.0.0 Release 151 Scope The present document describes the procedures allowing the technical realization of the real time
29、 end-to-end facsimile group 3 service within the UMTS PLMN using non-transparent network support according to the definition of the Teleservices 61 and 62 specified in 3GPP TS 22.003. Within the present document particular attention is given to Teleservice “Alternate speech/facsimile group 3“ (Teles
30、ervice 61). However, the definitions apply also to Teleservice “Automatic facsimile group 3“ (Teleservice 62) with the exception of all actions concerned with the speech phase. Consequently, in the following descriptions the term “Teleservice“ denotes both Teleservice 61 and Teleservice 62 as approp
31、riate. NOTE: V.25bis is outdated. References to V.25bis procedures need to be replaced by corresponding procedures based on V.250 and 3GPP TS 27.007. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - Refere

33、M document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TS 22.003: “Circuit Teleservices supported by a Public Land Mobile Network (PLMN)“. 2 3GPP TR 23.910: “Circuit Switch Data Bearer Services“. 3 3GPP TS 24

E-T.38 is based on ITU-T Recommendation T.38, but there are some differences with regar
43、ds to the packet elements, transcoding methods, and the procedure of controlling signals. The same procedure as T.38 is used for the structure of the frame and the protocol stack (Refer to the following clause, annex A and T.38 for the details). TAF: TAF usually shows a function of the UE side, but
44、when IWF has the function that is equal to the UE side TAF, TAF is used to express the function of the IWF in the present document. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: AAL2 ATM Adaptation Layer type 2 ARQ Automatic Retransmission Request BCS
