25、ase 141 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
26、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 user data are specified at TS 23.107. 2 References The following documents contain provisions which,

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.

ETSI ETSI TS 122 034 V14.0.0 (2017-03)73GPP TS 22.034 version 14.0.0 Release 143.2 Definitions For the purposes of the present document, the following terms and definitions apply: Fixed Netw
32、ork 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. For NT services it is the maximum possible AIUR. maximum possible GERAN AIUR: highest possible GERA
33、N 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 given number of TCH/F with a given channel coding to a FNUR that is lower than the maximum possible AIU
34、R. 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 defines mechanisms for the use of air interface resources which makes efficient and flexible use of hi
35、gher 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 at the higher rates. Data compression shall be applicable to NT GBS. Supplementary Services applica
36、ble 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 Bearer Services, and they are as follows: - asynchronous; - synchronous. 4.4 Parameters to be indicat
37、ed 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); - maximum number of GERAN TCH/F (that the mobile user can accept); - wanted AIUR (desired rate that th
38、e 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; - channel coding asymmetry indication. ETSI ETSI TS 122 034 V14.0.0 (2017-03)83GPP TS 22.034 version 14
39、.0.0 Release 14Some 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 mobile at call set-up and is not negotiable. It indicates the GERAN channel coding(s) that may be cho
40、sen 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 essential parameter for charging. It sets the upper limit of number of TCH/F that the network may allocate t
41、o 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 exception where the network is allowed to exceed the wanted AIUR is when the network can achieve the GERAN
42、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, 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
43、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 coding asymmetry indication is only applicable to NT calls where the user has indicated acceptance f
44、or 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 asymmetry. The channel coding asymmetry indication is only applicable in direction UE to network. 4.
45、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 can make use of HSCSD. The GERAN channel coding selected must be one of the channel coding(s) indica
46、ted 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 equal to the FNUR. 4.4.1.2 NT services The ME or the network may propose to modify the FNUR. The call
47、ing 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 calls the radio resource parameters must remain within limits that allow the transparent call to maint
48、ain 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 maximum number of TCH/F is not exce
49、eded 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.
