8、his 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 signalling aspects of the interworking within the digital cellula

9、r 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 identifying change of release date and an increase in version

10、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 incremented for all other types of changes, .e. technical enhancements, corrections, updates, etc. The specification from which this

11、 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.

12、5 0153221 507 Page 7 GSM 09.03 version 5.0.0: December 1996 1 Scope The purpose of this Global System for Mobile communications Technical Specification (GTS) is to present the general requirements for the Public Switched Telephone Network (PSTN) and the Integrated Services Digital Network (ISDN) as

13、well as for the mobile network to be met in order to ensure a correct integration of the mobile service in the fixed network. This technical specification covers only the signalling aspects of the interworking. The service requirements are covered in a specific specification: only the signalling imp

14、acts are dealt with here. 2 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

22、breviations Abbreviations used in this GTS are listed in GSM 01.04. 4 General signalling requirements 4.1 Requirements for the mobile network In order to be integrated in the fixed network the PLMN must comply with the following requirements: The Mobile Application Part (MAP) which supports informat

23、ion exchanges between the nodes of the mobile service uses the facilities of Transactions Capabilities (TC) of Signalling System No. 7 (SS7). Therefore the equipments of the mobile network must comply with the specifications of the interface between TC and the application user. If TC functions are i

24、ntegrated in the mobile network equipments, the latter must comply with the relevant specifications (CCITT Recommendations Q.771 to Q.774). For MAP messages routing purpose, the mobile nodes must provide the Signalling Connection Control Part (SCCP) via TC with an address complying with the relevant

25、 specifications (CCilT Recommendations Q.711 to Q.714). For call Set-up, the Mobile-services Switching Centres (MSCs) must interface with the fixed exchanges. In the detailed interworking specifications, the fixed network signalling considered are the SS7 and its User Parts (Telephone User Part (TUP

26、) or Integrated Services Digital Network User Part (ISUP). The MSCs must comply with the same signalling interface specifications as the fixed exchanges. The Public Land Mobile Network (PLMN) and the signalling on the radio path must provide the information needed to ensure a correct interworking wi

27、th the fixed network. The interworking in the MSCs must occur with a minimum loss of information. The PLMN nodes must interface with the SS7 signalling network. For that, they must comply with the Message Transfer Part (MTP) specifications (CCITT Recommendations (3.701 to Q.707). The signalling inte

28、rface between ISDN and PLMN is described in ETS 300 303. STD*ETSI GSM 07.03-ENGL 177b W 3400655 0353223 38T Page 9 GSM 09.03 version 5.0.0: December 1996 5 Impact of the off-air call set-up (OACSU) on the interworking The use of OACSU in the PLMN has an impact on the interworking with the fixed netw

29、ork. Both outgoing and incoming calls have to be considered: the consequences are not the same. The use of the OACSU procedure is optional and must be limited to national telephone calls only (see GSM 03.01). 5.1 Definition of OACSU To save the radio resources, the radio traffic channel may be alloc

30、ated to the communication only when both calling and called parties are present, .e. at the answer instant. This method called “Off-Air Call Set-up“ (OACSU) has some implication on the interworking with the fixed network. But the consequences are not the same whether the mobile subscriber is the cal

31、ling or the called party. 5.2 Outgoing call from a mobile station Upon initiation of an outgoing call, a traffic channel is allocated to the communication when the called subscribers answer is received in the MSC. In some cases, no idle traffic channel may be available when necessary. Therefore an a

32、ppropriate announcement must be given to the called party when no idle traffic channel is available within a certain intetval upon receipt of the called partys answer. Whenever the announcement is used, it must always be played through in its entirety, even if a traffic channel becomes available bef

33、ore it is completed, except if the called party clears, in which case the call should be cleared forward. If the ADDRESS COMPLETE message (ACM) indicates that there will possibly be no ANSWER message upon the connection of the called party (e.g. ACM without any information), the radio path must be e

34、stablished immediately upon receipt of the ACM. This applies in all cases on receipt of the ADDRESS COMPLETE message in TUP and ISUP (e.g. also in case the value “subscriber free“ is received. Due to interworking constraints coming from the characteristics of the different signalling systems used in

35、 the countries, the OACSU technique should only be used for national calls. 5.3 Incoming call to a mobile station For incoming calls, the impact is not so important, but some rules must be applied in order to limit the influence on the service quality. Concerning the sending instant of the answer me

36、ssage, the normal operating rules apply. If the call is successfully Set-up to the mobile station, the answer message must be sent to the originating exchange only when the traffic channel is established upon recognition of the called party connection.
