8、 5.0.0: May 1996 Foreword This Global System for Mobile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This GTS is an introduction to the 05 series of the digital
9、 mobile cellular and personal communication systems operating in the 900 MHz and 1800 MHz band (GSM 900 and DCS 1800). This GTS is a TC-SMG approved GSM technical specification version 5, which contains GSM Phase 2+ enhancementdfeatures to the version 4 GSM technical specification. The ETS from whic
10、h this Phase 2+ GTS has evolved is Phase 2 GSM ETS 300 573 edition 4 (GSM 05.01 version 4.6.0). GTS are produced by TC-SMG to enable the GSM Phase 2+ specifications to become publicly available, prior to submission for the formal ETSI standards approval procedure to become European Telecommunication
11、s Standards (ETS). This ensures the earliest possible access to GSM Phase 2+ specifications tor all Manufacturers, Network operators and implementors of the Global System for Mobile communications. The contents of this GTS are subject to continuing work within TC-SMG and may change following formal
12、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: Version 5.x.y where: y the third digit is incremented when editorial only changes have been incorporated in the
13、specification; x the second digit is incremented for all other types of changes, .e. technical enhancements, corrections, updates, etc. The specification from which this GTS has been derived was originally based on CEPT documentation, hence the presentation of this GTS may not be entirely in accorda
14、nce with the ETSI rules. Reference is made within this GTS to GSM-TSs (note). 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 Spec
15、ifications (GSM-TSs). These TSs may have subsequently become I-ET% (Phase l), 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 syst
16、em. These version 5.x.x GSM Technical Specifications may be referred to as GTSs.

26、 1.2 Abbreviations Abbreviations used in this GTS are listed in GSM O1 .O4 l. 2 Set of channels The radio subsystem provides a certain number of logical channels that can be separated into two categories according to GSM 04.03 5: 1) the traffic channels (TCH): they are intended to carry two types of
27、 user information streams: encoded speech and data. Two types of traffic channels are defined: Bm or full-rate (TCH/F) and Lm or half-rate (TCH/H) traffic channels. For the purpose of this series of technical specifications, the following traffic channels are distinguished: - - - - - - - - cell broa
28、dcast channel (CBCH) full rate speech TCH (TCH/FS) half rate speech TCH (TCH/HS) 9,6 kbits full rate data TCH (TCH/F9.6) 4,8 kbits full rate data TCH (TCH/F4.8) 4,8 kbits half rate data TCH (TCH/H4.8) s 2,4 kbits full rate data TCH (TCH/F2.4) 52,4 kbitc half rate data TCH (TCH/H2.4) 2) the signaling
29、 channels: these can be sub-divided into BCCH (broadcast control channel), CCCH (common control channel), SDCCH (stand-alone dedicated control channel) and ACCH (associated control channel). An associated control channel is always allocated in conjunction with, either a TCH, or a SDCCH. Two types of
30、 ACCH are defined: continuous stream (slow ACCH) and burst stealing mode (fast ACCH). For the purpose of this series of technical specifications, the following signalling channels are distinguished: stand-alone dedicated control channel, four of them mapped on the same basic physical channel as the
31、CCCH (SDCCH/4) stand-alone dedicated control channel, eight of them mapped on a separate basic physical channel (SDCCHB) full rate fast associated control channel (FACCH/F) half rate fast associated control channel (FACCH/H) slow, TCH/F associated, control channel (SACCHTTF) slow, TCH/H associated,
32、control channel (SACCHKH) slow, SDCCH/4 associated, control channel (SACCH/C4) slow, SDCCH8 associated, control channel (SACCH/C8) broadcast control channel (BCCH) random access channel (e uplink CCCH) (RACH) paging channel (part of downlink CCCH) (PCH) access grant channel (part of downlink CCCH) (
33、AGCH) notification channel (part of downlink CCCH) (NCH) When there is no need to distinguish between different sub-categories of the same logical channel, only the generic name will be used, meaning also all the sub-categories (SACCH will mean all categories of SACCHs, SACCHTT will mean both the sl
34、ow, TCH associated, control channels,). The logical channels mentioned above are mapped on physical channels that are described in this set of technical specifications. The different physical channels provide for the transmission of information pertaining to higher layers according to a block struct
35、ure. Page 9 GSM 05.01 Version 5.0.0: May 1996 3 Reference configuration For the purpose of elaborating the physical layer specification, a reference configuration of the transmission chain is used as shown in annex A. This reference configuration also indicates which parts are dealt with in details
36、in which technical specification. It shall be noted that only the transmission part is specified, the receiver being specified only via the overall performance requirements. With reference to this configuration, the technical specifications in the 05 series address the following functional units: -
37、- - - GSM 05.02: burst building, and burst multiplexing; GSM 05.03: coding, reordering and partitioning, and interleaving; GSM 05.04: differential encoding, and modulation; GSM 05.05: transmitter, antenna, and receiver (overall performance). This reference configuration defines also a number of poin
38、ts of vocabulary in relation to the name of bits at different levels in the configuration. It must be outlined, in the case of the encrypted bits, that they are named only with respect to their position after the encryption unit, and not to the fact that they pertain to a flow of information that is
39、 actually encrypted.

A summariced description appears in table 1, in terms of net bit rate, length and re
40、currence of blocks.

43、bits for class I and 78 bits for class li). For half rate speech, the block is divided into two classes according to the importance o the bits (95 bits for class I and 17 bits for class li). For data services, the net bit rate is the adaptation rate as defined in GSM 04.21. On SACCH, 16 bits are res
44、erved for control information on layer 1, and 168 bits are usec for higher layers. CCCH channels are common to all users of a cell; the total number of blocks (m, n, p, r: per recurrence period is adjustable on a cell by cell basis and depends upon the parameters (BS-CC-CHANS, BS-BCCH-SDCCH-COMB, BS
45、-AG-BLKS-RES anc NCP) broadcast on the BCCH and specified in GSM 05.02 and GSM 04.08.

46、ith eight basic physical channels per carrier. The carrier separation is 200 kHz. A physical channel is therefore defined as a sequence of TDMA frames, a time slot number (modulo 8) and a frequency hopping sequence. The basic radio resource is a time slot lasting = 576,9ps (15126 ms) and transmittin
47、g information at a modulation rate of = 270.833 kbit/s (1625/6 kbit/s). This means that the time slot duration, including guard time, is 156,25 bit durations. We shall describe successively the time frame structures, the time slot structures and the channel organization. The appropriate specificatio
48、ns will be found in GSM 05.02 (multiplexing and multiple access). 5.1 Hyperframes, superframes and multiframes A diagrammatic representation of all the time frame structures is in figure 1. The longest recurrent time period of the structure is called hyperframe and has a duration of 3h 28mn 53s 760m
49、s (or 12533,76 s). The TDMA frames are numbered modulo this hyperframe (TDMA frame number, or FN, from O to 2715647). This long period is needed to support cryptographic mechanisms defined in GSM 03.20. One hyperframe is subdivided in 2048 superframes which have a duration of 6.12 seconds. The superframe is the least common multiple of the time frame structures. The superframe is itself subdivided in multiframes; two types of multiframes exist in the system: - - a 26-frame multiframe (51 per superframe) with a duration of 120 ms, comprising 26 TDMA frames.
