ETSI ETSI TS 122 034 V13.0.0 (2016-02)63GPP TS 22.034 version 13.0.0 Release 131 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
26、 used for user rates that can be achieved with one or more TCH/F. Multislot also defines a flexible use of 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

32、ions 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: user rate between Mobile Termination and IWF. For T services it is the maximum possible AIUR not including padding.
33、 For NT services it is the maximum possible AIUR. maximum possible GERAN AIUR: highest possible GERAN AIUR 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 giv
34、en number of TCH/F with a given channel coding to a FNUR that is lower than the maximum possible AIUR. 4 Description 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 de
35、fines mechanisms for the use of air interface resources which makes efficient and flexible use of higher user 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
36、 at the higher rates. Data compression shall be applicable to NT GBS. Supplementary Services applicable to 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 B
37、earer Services, and they are as follows: - asynchronous; - synchronous. 4.4 Parameters to be indicated and 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); -
38、maximum number of GERAN TCH/F (that the mobile user can accept); - wanted AIUR (desired rate that the mobile 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; - c
39、hannel coding asymmetry indication. ETSI ETSI TS 122 034 V13.0.0 (2016-02)83GPP TS 22.034 version 13.0.0 Release 13Some of the parameters are only utilised by GERAN. When UTRAN radio access bearer is allocated the values are ignored. The GERAN channel coding(s) acceptable shall be indicated by the m
40、obile 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 at call set-up. It enables the mobile user to limit the number of GERAN TCH/F used and thus to control an essentia
41、l 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 that the mobile user wants and which the network shall try to reach but which it is not allowed to exceed. The excepti
42、on 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 GERAN 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, the
43、n 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. 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
44、coding asymmetry indication is only applicable to NT calls where the user has indicated acceptance for channel 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
45、asymmetry. The channel coding asymmetry indication is only applicable in direction UE to network. 4.4.1.1 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
46、can make use of HSCSD. The GERAN channel coding selected must be one of the channel coding(s) indicated in 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 e
47、qual to the FNUR. 4.4.1.2 NT services The ME or the network may propose to modify the FNUR. The calling entity 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 ca
48、lls 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 indi
49、cated in the channel coding(s) acceptable parameter is used, the maximum number of TCH/F is not exceeded and the AIUR is kept constant. 4.4.2.2 NT services For NT calls the network may modify the number of TCH/F and the channel coding used at GERAN and thus also the AIUR during the call as long as the maximum number of TCH/F, and the channel coding(s) acceptable are all respected. The network shall try to reach the wanted GERAN AIUR indicated, as long as the resource situation allows it. ETSI ETSI TS 122 034 V13.0.0 (2016-02)93GPP TS 22.034 version 13.0.0
