27、1 Scope The present document specifies the Stage 1 description of High Speed Circuit Switched Data (HSCSD). HSCSD is a feature that introduce General Bearer Services and a multislot mechanism is used for user rates that can be achieved with one or more TCH/F. Multislot also defines a flexible use of
28、 air interface resources which makes efficient and flexible use of higher user rates feasible. The Multislot mechanism is only applicable to GERAN. At UTRAN radio access parameters used for GBS user data are specified at TS 23.107. 2 References The following documents contain provisions which, throu
29、gh reference in this text, constitute provisions of the 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 ve
30、rsion 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 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. 2 3GPP TS 22.002: “Bearer Se

33、User Equipment (same as MS in GSM specifications) Additional abbreviations can be found in TS 22.905 1. 3.2 Definitions For the purposes of the present document, the following terms and definitions apply: Fixed Network User Rate: user rate between IWF and the fixed network. Air Interface User Rate:
34、user rate between Mobile Termination and IWF. For T services it is the maximum possible AIUR not including padding. For NT services it is the maximum possible AIUR. ETSI ETSI TS 122 034 V15.0.0 (2018-07)73GPP TS 22.034 version 15.0.0 Release 15maximum possible GERAN AIUR: highest possible GERAN AIUR
35、 that the multiple TCH/F can provide, e.g. 2 TCH/F using TCH/F9.6 provides a maximum possible AIUR of 19,2 kbit/s. padding: fill bits needed to adapt the maximum possible AIUR supported by a given number of TCH/F with a given channel coding to a FNUR that is lower than the maximum possible AIUR. 4 D
36、escription 4.1 General HSCSD is a feature that introduce General Bearer Services (GBS) and a multislot mechanism is used for user rates that can be achieved with one or more TCH/F. HSCSD also defines mechanisms for the use of air interface resources which makes efficient and flexible use of higher u
37、ser rates feasible. The Multislot mechanism is only applicable to GERAN. 4.2 Applicability GBS shall provide flexible ways of supporting GSM Phase 2, T and NT data services and new data services at the higher rates. Data compression shall be applicable to NT GBS. Supplementary Services applicable to
38、 the General Bearer Services are specified at TS 22.004, 3. 4.3 General Bearer Services The General Bearer Services are defined in TS 22.002 2. The General Bearer Services (GBS) consist of two Bearer Services, and they are as follows: - asynchronous; - synchronous. 4.4 Parameters to be indicated and
39、 negotiated 4.4.1 Call set-up The parameters to be indicated, and negotiated, if applicable, during the call set-up shall include: - FNUR; - GERAN Channel coding(s) acceptable (for the call); - maximum number of GERAN TCH/F (that the mobile user can accept); - wanted AIUR (desired rate that the mobi
40、le user wants the network to allocate). The wanted AIUR is applicable to NT services only; - indication if the user initiated modification is required, and if so, the network resource needs; - channel coding asymmetry indication. Some of the parameters are only utilised by GERAN. When UTRAN radio ac
41、cess bearer is allocated the values are ignored. The GERAN channel coding(s) acceptable shall be indicated by the mobile at call set-up and is not negotiable. It indicates the GERAN channel coding(s) that may be chosen by the network for the call. The maximum number of GERAN TCH/F shall be indicated
42、 at call set-up. It enables the mobile user to limit the number of GERAN TCH/F used and thus to control an essential parameter for charging. It sets the upper limit of number of TCH/F that the network may allocate to the mobile. The wanted AIUR (applicable to NT services only) indicates the AIUR tha
43、t the mobile user wants and which the network shall try to reach but which it is not allowed to exceed. The exception where the network is allowed to exceed the wanted AIUR is when the network can achieve the GERAN AIUR with a lower number of TCH/F, e.g. wanted ETSI ETSI TS 122 034 V15.0.0 (2018-07)
44、83GPP TS 22.034 version 15.0.0 Release 15GERAN AIUR indicated by the mobile is 14,4 kbit/s, GERAN channel codings acceptable are both TCH/F9.6 and TCH/F4.8 and maximum number of TCH/F are 3, then the network shall choose 2 x 9,6 over 3 x 4,8 if a channel coding of TCH/F9.6 is available on two TCH/F.
45、 If the user wishes to make use of the user initiated modification procedure, this shall be indicated at the call set-up. It shall be possible to reserve a different FNUR than the AIUR. Channel coding asymmetry indication is only applicable to NT calls where the user has indicated acceptance for cha
46、nnel coding(s) based on enhanced modulation. In this case the user may indicate preference for channel coding symmetry, downlink biased channel coding asymmetry, or uplink biased channel coding asymmetry. The channel coding asymmetry indication is only applicable in direction UE to network. 4.4.1.1
47、T services The ME or the network may propose to modify the FNUR. The calling entity may accept or release the call. Autobauding is not allowed. The AIUR is always equal to the FNUR. Fax Group 3 can make use of HSCSD. The GERAN channel coding selected must be one of the channel coding(s) indicated in
48、 the channel coding(s) acceptable parameter, the number of TCH/F selected shall not exceed the maximum number of TCH/F parameter, and the combination of the two shall result in an AIUR that is equal to the FNUR. 4.4.1.2 NT services The ME or the network may propose to modify the FNUR. The calling en
49、tity may accept or release the call. Autobauding is allowed. The wanted AIUR is indicated by the mobile at call set-up. 4.4.2 Network initiated modification 4.4.2.1 T services For transparent calls the radio resource parameters must remain within limits that allow the transparent call to maintain it is characteristics of fixed end to end throughput and delay. This means that in GERAN the channel coding and the number of TCH/F used may change during the call as long as a channel coding indicated in the channel coding(s) acceptable parameter is used, the maxi
