13、oduction to the 08.5 - 08.6 series of GSM Technical Specifications and deals with the definition of the Base Station Controller (BSC) to Base Transceiver Station (BTS) interface defined inside the base station system (BSS) for the GSM system. These Technical Specifications define the basic interface

14、 with some identified options requiring further elaboration. The BSC-BTS interface is mandatory within GSM only if the BSC and the BTS are not collocated. 1.1 Normative references This GTS incorporates by dated and undated reference, provisions from other publications.

28、ubscribers. In addition it shall also allow control of the radio equipment and radio frequency allocation in the BTS. 3 Interface specification objectives The BSC to BTS interface specifications should allow the following: (i) Connection of various manufacturers BTSTTRX to the same BSC, according to

29、 the location of the transcoder. (i) The use of several manufacturers BSC to the same type of BTSRRX, according to the location of the transcoder. (iii) The use of the same BTSTTRX in any PLMN, according to the location of the transcoder. (iv) The use of the same BSC in any PLMN. (v) Separate evolut

30、ion of BSC and BTSTTRX technology. (vi) (vi) Separate evolution of O b) channel structures; c) signalling transfer procedures; d) configuration and control procedures; e) operation and maintenance information support. The definition of the BSC to BTSTTRX interface follows a layered approach similar

31、to the ISDN. Layer 3 is for the most part based on GSM 08.08 with additional procedures for control of radio resources. Layer 2 is based on the LAPD protocol. Layer 1 is either digital (at a rate 2 048 kbihec with a frame structure of 32 x 64 kbisec time slots or at a rate of 64 kbisec.) or analogue

32、 with the data being passed by the use of modems (this latter case is a national option). In the case that the transcoder is positioned outside the BTS, the overall one way propagation delay between the Point Of Interconnection to PSTN/ISDN and the MS is limited to 1,5 ms (approximately 300 km). Wit

33、h the transcoder in the BTS, the limit is 6,5 ms (approximately 1 300 km). These limits may be subject to increase resulting from savings made in the overall network. See also GSM 03.50. 5 Other technical specifications on the BSC-BTS interface The full structure of the Technical Specifications spec

34、ifying the BSC to BTS interface are as follows: 5.1 GSM 08.52 BSC-BTS Interface Principles This specification gives the principle basis for the rest of the specifications specifyhg the interface between the base station controller and the base transceiver station. It gives the functional split betwe

35、en these two entities. 5.2 GSM 08.54 BSC-BTS Layer 1 Specification This specification defines the structure of the physical layer at the BSC - BTS interface. The physical interface is either chosen as 2 048 kbisec or as 64 kbisec, both according to standard CCITT recommendations. Depending on locati

36、on of transcoders, speech is standard A-law or it is 16 kbisec remote control protocol multiplexed or rate adapted to 64 kbit/sec in the same way as data. Page 10 GSM 08.51 version 5.0.0: December 1996 5.3 GSM 08.56 BSC-BTS Layer 2 Specification At layer 2 the signalling information is passed by a s

37、tandard LAPD protocol mechanism in accordance with the CCITT Recommendations (2.920 and (2.921. 5.4 GSM 08.58 BSC-BTS Layer 3 Specification This specification specifies the layer 3 procedures used on the BSC-BTS interface for control of the GSM services. The functional split between BSC and BTS is d

38、efined in GSM 08.52. 5.5 GSM 12.21 BSC-BTS OperationlMaintenance Signalling This specification defines the transport mechanism for O&M messages over the Abis-interface. O&M procedures and messages are defined in GSM 12 series. 5.6 GSM 08.60 Inband Control of Remote Transcoders and Rate Adaptors The

39、transcoder is a part of the BSS and may optionally be located outside the BTS (e.g. at MSC-site or at BSC-site) in order to make it possible to multiplex speech and data channels on the links within the BSS and on the BSC-BTS link. This specification describes the protocol which carries the full rat

40、e speech and data frames between the transcoder and the radio link codec across a 16 kbisec interface. Both full rate speech and full rate data services are covered. It also defines the signals needed for remote controlling the timing of the transcoder in accordance to the transmission time at the r

41、adio link. It also addresses the signals for voice activity and comfort noise. It interfaces the 06- series to the OSseries. 5.7 GSM 08.61 Inband Control of Remote Transcoders and Rate Adaptors for Half Rate Traffic Channels This Technical Specification describes the protocol which carries the half

42、rate speech and data frames between the transcoder and the radio link codec across a 16 kbisec or an 8 kbisec interface. Both half rate speech and half rate data services are covered. It also defines the signals needed for remote controlling the timing of the transcoder in accordance to the transmis

43、sion time at the radio link. It also addresses the signals for voice activity and comfort noise.
