14、has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This GTS gives the interface principles Base Station System (BSS) to Mobile-services Switching Centre (MSC) interface within the digital cellular telecommunicat

15、ions system. The contents of this GTS are subject to continuing work within TC-SMG and may change following formal 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 follow

16、s: 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 all other types of changes, .e. technical enhancements, corrections, updates, etc. The specification from which this GTS has been de

17、rived was originally based on CEPT documentation, hence the presentation of this GTS may not be entirely in accordance with the ETSI rules. 1 General 1.1 Scope This Global System for Mobile communications Technical Specification (GTS) gives the principles on which the detailed interface specificatio

18、ns in the rest of the GSM 08.0X series of Technical Specifications are based. The set of fixed equipment accessed from the MSC through one particular instance of the interface will be later referred to as a Base Station System (BSS). A BSS ensures the coverage of n cells, where n can be 1 or more. T

19、he function of a BSS may be further subdivided into a control function, performed by one Base Station Controller (BSC) and a transceiving function, performed by “n“ Base Transceiver Station equipments (BTS), one for each cell. However, the study of such a split is outside the scope of the 08.0 serie

20、s of Technical Specifications, where the BSS will be considered as a whole. The BSS-MSC interface defined in the GSM 08 series of Technical Specifications is designed to support a wide range of possible architectures on both sides. Characteristics like the physical location of the transcodershate ad

21、aptation inside the BSS (either integrated into the transceivers or very near to the MSC) or the use of traffic or signalling concentration at either side are left to the operators choice. Annex A to this GTS contains guidance information concerning the use of remote mobile switching units, which fo

22、r the purposes of this GTS are considered as part of the MSC. Direct connection between two BSSs is not supported by this interface. This interface is based on the use of 1 or more 2 048 kbiffs digital transmission system interfaces. Each 2 048 kbiffs interface provides 31*64 kbiffs channels which c

23、an be used for traffic or signalling as the operator requires. The signalling is layered, terminology similar to that in the OS1 reference model is used in this series, however the layers referred to are not identical to the equivalently named layer in the OS1 model. This interface is defined at the

24、 boundary of the MSC and has a per channel bit rate of 64 kbiWs, but the net radio path traffic channel is at a rate of less than 16 kbiffs. A transcoder or rate adapter function is thus needed for the rate conversion. The interface is designed such that the transcoding or rate adaptation function m

25、ay be geographically situated at either the MSC site or the BSS site, however the transcoder is considered to be part of the BSS. The interface has been designed around the aims of GSM08.01 allowing each component and the system as a whole to evolve. 1.2 Normative references This GTS incorporates by

26、 dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter.

42、ey and permitted algorithms from MSC 2.1 Terrestrial channel management 2.1.1 Terrestrial channel allocation Terrestrial channel allocation will be handled in the following manner. The link between the MSC and the BSS will be considered by the BSS and the MSC as a route on “n“ circuits. Within this

43、route, certain of the circuits may not be able to support all types of traffic (e.g., data calls or half rate connections). This can be managed, according to the configuration, either by the MSC or by the BSS for a given route. The entity in charge of circuit allocation chooses the terrestrial circu

44、it, whilst ensuring that the chosen circuit is able to support the type of connection needed. 2.1.2 Blocking of terrestrial channels The entity not allocating the circuits shall be able to remotely block the terrestrial channel and remove it from service. This is signalled across the BSS/MSC interfa

45、ce using the appropriate signalling exchange as defined in GSM 08.08. Local blocking of terrestrial channels on the side allocating the circuits may be supported and will result in the concerned channels not being chosen, no information need flow across the interface in these cases. 2.2 Radio channe

46、l management 2.2.1 Channel configuration management The channel configuration management will be controlled between BSS and maintenance centre, the MSC holding no direct data concerning the allocation of radio timeslots etc. 2.2.2 Radio TCH management 2.2.2.1 Radio channel allocation The BSS shall c

47、hoose the radio channel to be used on the appropriate cell, based on information received from the MSC, which defines the channel type, channel coding and all other parameters relevant to defining channel type. The chosen radio channel shall be connected to the terrestrial channel in order to suppor

48、t the call. This connection mechanism is not further defined in these Technical Specifications. 2.2.2.2 TCH radio link supervision Radio link supervision of dedicated radio resources shall be the responsibility of the BSS. If communication with the mobile is lost then the BSS can request that the ca

49、ll be cleared. 2.2.2.3 Frequency hopping management Frequency hopping management shall be performed by the BSS. That is the BSS shall store and transmit all hopping parameters for the cell(s) that it controls, the hopping shall be performed such that it is not visible on the BSS/MSC interface.
