21、pecification (TS) has been produced by ETSI 3rd Generation Partnership Project (3GPP). The present document specifies the Stage 2 description of High Speed Circuit Switched Data (HSCSD) within the 3GPP system.

Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2
23、presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporate
24、d in the document. ETSI ETSI TS 123 034 V14.0.0 (2017-03)53GPP TS 23.034 version 14.0.0 Release 141 Scope The present document contains the stage 2 service description for a High Speed Circuit Switched Data (HSCSD) on GSM/GERAN in A/Gb mode and Iu mode. HSCSD utilizes the multislot mechanism, i.e. u
25、sing multiple traffic channels (/bearers) for the communication. Additionally, the present document specifies some HSCSD related requirements for multi system mobile stations operating in UTRAN Iu mode. In UTRAN Iu mode one bearer can provide all needed data rates, and the multislot mechanism is the
26、refore not needed. However, for inter-system handover to GERAN, certain information has to be provided by the mobile station during the service negotiation. The UTRAN Iu mode aspects concerning HSCSD are described exclusively in clause 4.2. In analogy with ITU-T Recommendation I.130 6 (refer to anne
27、x A) and with reference of ITU-T Recommendation Q.65 7 VI.1 (Stage 2 of the method for characterization of services supported by an ISDN), the second stage of the HSCSD is defined as follows. Stage 2 identifies the functional capabilities and information flows needed to support the service as descri
28、bed in 3GPP TS 22.034 9. Furthermore, it identifies various possible physical locations for the functional capabilities. The output of Stage 2, which is signalling system independent, is used as an input to Stage 3, the design of signalling system and switching Recommendations. 2 References The foll

ETSI ETSI TS 123 034 V14.0.0 (2017-03)73GPP TS 23.034 version 14.0.0 Release 144 Main concepts The air i
43、nterface user rate in the original GSM data transmission is limited to 9,6 kbps with the 12 kbps air interface rate. The HSCSD described in the present document Stage 2 description allows higher air interface user rates to be used for transparent and non-transparent data services. NOTE: In the prese
44、nt document the term “air interface user rate“ corresponds to the transfer rate in radio interface for user data and “air interface rate“ includes additional data related to transmission protocols. HSCSD is a feature enabling the co-allocation of multiple full rate traffic channels (TCH/F) into a HS
45、CSD configuration. The aim of HSCSD is to provide a mixture of services with different air interface user rates by a single physical layer structure. Further improvements in data rates are achieved through enhancement of the radio interface (modulation and coding schemes), which allows higher bit ra
46、tes per one GSM time slot. The available capacity of a HSCSD configuration is several times the capacity of a TCH/F, leading to a significant enhancement in the air interface data transfer rate. Figure 1 represents the network architecture to support HSCSD in A/Gb mode based on the concept of multip
47、le independent channels in one HSCSD configuration. Figure 1a represents the network architecture to support HSCSD in GERAN Iu mode. NOTE: 3GPP TS 43.051 18 does not specify the GERAN internal interface between BSC and BTS. In case when enhanced modulation is used the number of time slots in the rad
48、io interface may not correspond to the number of data streams in the network side, for example a 28,8 kbps service may be offered through one air interface time slot, but it requires two 14,4 (16 kbps) Abis channels. Another example is bit transparent 56 kbps to 64 kbps service where two air interfa
49、ce time slots of 32 kbps are multiplexed onto one 64 kbps data stream on the network side.
