15、rd 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 the technical realization of facsimile group 3 using non-transpar

16、ent network support for the European digital cellular telecommunications system. 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 contents of this GTS it will then be republished by ETSI with an identifyin

17、g 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 specif ication; x the second digit is incremented for all other types of changes, .e. technical enhancements, correct

18、ions, 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 ETSVPNE rules.

19、3400855 0159133 891 = Page 7 GSM 03.46 Version 5.0.0: November 1996 1 Scope This Global System for Mobile communications Technical Specification (GTS) deals with the procedures allowing the technical realization of the real time end-to-end facsimile group 3 service within the GSM PLMN using non-tran

20、sparent network support according to the definition of the Teleservices 61 and 62 specified in GSM 02.03. Within this document particular attention is given to Teleservice “Alternate speechlfacsimile group 3“ (Teleservice 61). However, the definitions apply also to Teleservice “Automatic facsimile g

21、roup 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 appropriate. NOTE: Some facilities associated with alternate speech/ facsimile group3 may n

22、ot be available with version 1 of MAP. In particular, the in-call modification procedure following an inter MSC handover is not supported by this version. This imposes the limitation that for all calls it will not be possible to change between speech and facsimile following an inter MSC handover. 2

These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of t

35、network facsimile group 3 service, as basically defined in CCIlT Recommendation F.160, is an international telematic service for document transmission between two facsimile group 3 terminals. The service specifications are comprised of two parts: - - the control procedures described in CCIlT Recomme

36、ndation T.30 and the document transmission coding described in CCIlT Recommendation T.4. The GSM facsimile group 3 Teleservice is intended to allow connections between facsimile group 3 terminals using: - - a GSM PLMN as stand-alone facility for mobile-to-mobile communication; a GSM PLMN to have acc

37、ess to fixed networks PSTN and/or ISDN for mobile to/from fixed network communication. STD-ETSI GSM 03-4b-ENGL L77b 3400855 UL57L35 bb4 Page 9 GSM 03.46 Version 5.0.0: November 1996 For this Teleservice, the coding of the facsimile document is as per CCITT Recommendation T.4 and the protocol as per

38、CCIlT Recommendation T.30 both modified within the PLMN as detailed in this specification. The interworking between different networks is based on CCIlT Recommendation X.300. The particular features o this Teleservice are: - it uses point-to-point communication; - the information transfer mode is ci

39、rcuit, duplex, synchronous; - the information transfer capability is alternate speech/ facsimile group 3 or facsimile group 3 only; - both mobile originated and mobile terminated calls are supported; - different end-to-end message speeds as per CCITT Recommendation T.30 may be used within the same c

40、onnection to match the appropriate quality requirements; - use of the standard synchronous terminal adaptation function for non-transparent network support (as per GSM 07.03) within the MS is envisaged. 4 Network architecture The network architecture applicable to this Teleservice is shown in figure

41、 1/03.46 below. Figure 1/03-46: Network architecture It shows the case of mobile to fixed network interworking. For mobile-to-mobile calls, there would effectively be a loop back within the PLMN using two IWFs. Page 10 GSM 03.46 Version 5.0.0: November 1996 II 5 Reference configuration at the mobile

42、 station MT2 The mobile station reference configurations described in this clause are defined as per GSM 04.02. II TA II MT1 Figure Z03.46: Reference configurations e) Il TA The teleservice definitions in GSM 02.03 regard the facsimile group 3 terminal as a 2-wire analogue terminated equipment. In o

43、rder to connect this to the MT2 a separate “fax adaptor“ device is necessary. This configuration, shown in figure 2d03.46, has to be considered as the standard configuration, so that all the existing facsimile group 3 terminals can be connected to the PLMN. II MT1 An alternative realization would be

44、 to combine a facsimile group 3 terminal and the fax adaptor into a special “GSM facsimile machine“, directly providing a digital output. Although such a terminal must appear to the MT2 as identical as the fax adaptor (.e. with an identical interface and protocol), it would allow for a significantly

45、 smaller and simpler facsimile machine. This configuration is shown in figure 2d/03.46. In addition of course, it is always possible to realize an MTO, as per figure 2f/03.46, where both the facsimile and mobile termination functions are considered to be pari of one integrated unit. The remaining co

46、nfigurations concern the use of an S interface and are considered as optional configurations. Their use is for further study. The particular terminal adaptation functions used are those detailed in GSM 07.03 for non-transparent bearer capability. The interface to the MT2 used is according to CCITT R

47、ecommendation V.24 with an option for support of CCIT Recommendation V.25bis procedures for auto calling and auto answering.

48、re 3/03.46, is intended to specifically complement the facsimile group 3 terminal in order to be able to communicate over a GSM PLMN. Handling u Figure W03.46: Fax adaptor scheme Whether it has to be a function internal to the GSM PLMN, or an external accessory associated with the facsimile group 3

49、terminal, is beyond the scope of this specification, and in any case, does not affect the working of the procedure as described here. It can be functionally partitioned in two sections: - an analogue section, dealing with: - the modulation and demodulation processes according to CCIll Recommendation V.21, V.27ter, and V.29 as explained in CCIlT Recommendation T.4 and T.30; - handling of the signalling on the 2-wire path to the associated facsimile terminal, including auto calling and auto answering functions where necessary (see clause 8). - a digital section, deal
