25、3Li00855 0242878 834 Page 7 GSM 08.58 version 5.5.0: October 1997 Foreword This Global System for Mobile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) of the European Telecommunications Standards Institute (ETSI). This GTS specifies the general stru

26、cture of layer 3 and traffic management procedures and messages used on the A-bis interface to support signa Hing procedures within the digital cellular telecommunications system. This GTS is a SMG approved GSM technical specification version 5, which contains GSM Phase 2+ enhancementdfeatures to th

27、e version 4 GSM technical specification. The ETS from which this Phase 2+ GTS has evolved is Phase 2 GSM ETS 300 596 Edition 4 (GSM 08.58 version 4.9.0). The contents of this GTS are subject to continuing work within SMG and may change following formal SMG approval. Should SMG modify the contents of

28、 this GTS it w ill 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 specification; x the second digit is incremented for

29、 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 accordance with the ETSI rules. Page 9 GSM 08.58 version 5.

30、5.0: October 1997 1 scope The use and general aspects of the Base Station Controller (BSC) to Base Station Transceiver (BTS) interface (the A-bis interface) are given in GSM 08.51. This Global System for Mobile communications Technical Specification (GTS) specifies the general structure of layer 3 a

31、nd traffic management procedures and messages used on the A-bis interface to support signalling procedures as defined in GSM 04.08. Network management procedures and messages for the A-bis interface are defined in GSM 08.59. The functional split between BSC and BTS is defined in GSM08.52. The proced

32、ures and messages required to support this split are defined in detail in this GTS. 1.1 Normative references This GTS incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are l

33、isted hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this GTS only when incorporated in it by amendment or revision.

44、 October 1997 MS BTS BSC I I abnormal case ERROR IND 4 Dedicated channel management procedures 4.1 Channel activation This procedure is used to activate a channel at the BTS for an MS which later will be comman ded to this channel by an IMMediate ASSIGN, an ASSIGN CoMmanD, an ADDitional ASSIGNment;

45、a NOTIFICATION, a CHANNEL RELEASE (with a Channel description) a HANDOver CoMmanD or a CONFiguration CHange CoMmanD message. In the handover case, the procedure is used between the target BSC and the target BTS to activate a channel for a subsequent handover from the old BTS. 4.1.1 Signalling Proced

46、ure BSC determines what channel shall be used and starts that channel at BTS by sending a CHANnel ACTIVation message to the relevant TRX. This message contains the reason for the activation (immediate assignment, assignment, acynchronous/synchronous handover, additional assignment, activation of a s

47、econdary channel in a multislot configuration), the identification of the channel to be used (channel no) and a complete description of the channel (fulVhalf rate, speecwdata, codinghate adaption, hopping sequence, encryption key etc.). If the Encryption Information field is present, the activation

48、is done with ciphering active. If the Encryption information element is not present, activation is done without ciphering. After activating the channel as requested, TRX responds with the CHANnel ACTIVation ACKnowledge message. This message contains the current frame number at BTS. The frame number

49、is used by BSC to determine the Starting Time parameter to be included in the following assignment message to MS. (A suitable number has to be added to current frame number to take all possible signa Iling delays into account) . MS TS CHAN ACTIV assignment to MS cc IMMediate A SIGN or ASSIGN CoMmanD or ADDitional ASSIGN or CHANNEL RELEASE or NOTIFICATION If the TRX for some reason cannot activate the resource as requested by the CHANnel Activation message, the TRX shall return a CHANnel ACTIVation Negative ACKnowledge message with the most appropriate cause value.
