10、ification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETS i). This GTS specifies stage two of the Packet Data on Signalling channels service (PDS) which allows packet data transmission in GSM networks on d

11、edicated channels 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+ enhancemenWfeatures. GTS are produced by TC-SMG to enable the GSM Phase 2+ specifications to become publicly av

12、ailable, prior to submission for the formal ETSI standards approval procedure to become European Telecommunications Standards (ETS). This ensures the earliest possible access to GSM Phase 2+ specifications for all Manufacturers, Network operators and implementors of the Global System for Mobile comm

13、unications. 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 number as follows

14、: 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. Reference is made within this GTS to GSM-TSs (note

15、). 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 subsequently become I-ETSs (Phase

16、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 Specifications may be referred to as

24、lications using short dialogues with a duration in the range of a few seconds. For transmission on the air interface, the service uses protocols of the CM sublayer, the PDSS1 and PDSS2 protocols. The provision of a mass market packet data service in GSM, where many users want to transfer very small

25、data packets, leads to a significant increase of signalling traffic. This may cause load problems especially for the SCCP on the A interface. The PDS service offers two variants in order to allow for efficient transmission within the network: PDSS1: PDSS2: Service offered at service access points in

26、 the mobile station and MSC which uses an underlaying MM connection and a signalling connection on the A interface (an SCCP connection): The service may be offered in parallel to other CM sublayer services; MSC controlled handover is possible during the transmission; the MM connection related functi

27、ons (subscription checks and MM security functions) are applicable. At radio link failure the mobile station may require re-establishment of the MM connection. The same subscription and charging mechanisms as for circuit switched services are applicable to the service. Service offered at service acc

28、ess points in the mobile station and a new network entity, the PDSS2-Support Node (PDSS2-SN), which has an interface to the BSS, the A interface, where an MM connection and a signalling connection on the A inteRace are not required: Mobile terminated CM establishment may not be possible during a PDS

29、S2 connection; more than one PDSS2 connection to a mobile station in parallel are not possible; with these exceptions, the service may be offered in parallel to other CM sublayer services. After a handover, dedicated channel assignment, or radio link failure the PDSS2 connection may be resumed; the

30、MM connection related functions, subscription checks, and MM security functions may not be applicable (but similar functions can be implemented in the application). The subscription and charging mechanisms defined in GSM for circuit switched services may not be applicable to the service (however, th

31、e application may implement such mechanisms). Only mobile originated establishment of a PDSS2 connection is possible. 4.1 Service characteristics of PDSS1 The PDSS1 service access points are at the MSCNLR and the MS. - The MSCNLR may be accessed to establish a PDSS1 connection for transmission of da

32、ta packets of a specific application, e.g. * SMS, ffs, or * a packet data protocol to a certain MS (identified by IMSI) which is supposed to be registered in the MSC area; - the MSC may also be accessed for a data request, .e. the request for transmission of the application on an established PDSS1 c

33、onnection, and for release of the connection; - at the SAP, the MSC may perform a data indication, .e. indicate a data packet received from the MS, and indicate establishment/release/abortion of a PDSS1 connection; - .at the SAP, the MSC may give an indication that data transfer has to be suspended

34、or can be resumed; - The MS may be accessed to establish a PDSS1 connection to the network for transmission of data packets of a specific application; ETSI GSM*03=63 76 3400855 0105774 4TL Page 9 GSM 03.63 Version 5.1 .O May 1996 - the MS may also be accessed for a data request, .e. the request for

35、transmission of a data packet on a established PDSS1 connection, and for release of the connection; - at the SAP, the MS may perform a data indication, .e. indicate a data packet received from the MSC, and indicate estabIishment/release/abortion of a PDSS1 connection; .at the SAP, the MS may give an

36、 indication that data transfer has to be suspended or can be resumed. The service quality is that one offered by the Um layer 1, layer 2, and layer 3 sublayers RR and MM to the Um layer 3 CM protocols, see TS GSM 05.05, TS GSM 04.06, TS GSM 04.07, and TS GSM 04.08 (transmission on the A and Abis int

From these specifications, e.g., - minimum, maximum, and mean time between PDSS1 establishment request and confirmation - - (dependent on certain system parameters and options), minimum, maximum, and mean time for fulfilling a data request, the fact t

38、hat until PDSS1 connection release or abortion, packets are transferred without loss and in the right order can be derived.
