In addition it also allows for the allocation of su
33、itable radio resources within the PLMN, and the operation and maintenance of those resources. 2 A-lnterface specification objectives The MSC to BSS interface specifications shall allow the following: i) ii) iii) iv) vi) vii) viii) VI Connection of various manufacturers BSSs to the same MSC; The use
34、of several manufacturers MSCs to the same type of BSS; The use of the same BSS in any PLMN; The use of the same MSC in any PLMN; The separate evolution of MSC and BSS technology, and; The separate evolution of O Evolution towards lower speech coding rates; Support of all services defined in the 3GPP
35、 TS 02 series of Technical Specifications. 3 A-Interface characteristics The interface is defiied to be at the boundary of the MSC. The MSC to BSS interface is specified by a set of characteristics, including: i) Physical and electromagnetic parameters; ii) Channel structures; iii) Network operating
36、 procedures; iv) Operation and Maintenance information support. The definition of the MSC to BSS interface follows a layered approach similar to that in the ISDN. Layer 3 is for the most part based on Technical Specification 3GPP TS 04.08 with additional procedures added for the control of radio res
37、ources and the identification of transactions using the SCCP. Layer 2 is based on the signalling systemNo.7 (SS N0.7) Message Transfer Part (MTP). Layer 1 is either digital (at 2 048 kbit/s, based on CCITT Rec. G703 clause 6) or analogue with the data being passed by the use of modems (this latter c
38、ase is a national option). 4 Other specifications on the MSC-BSS interface The full structure of the Technical Specifications speciSling the MSC to BSS link are as follows. 4.1 Technical Specification 3GPP TS 08.02 Interface Principles The present document deals with the functional split between the
39、 BSS and the MSC. This functional split is then supported by the other Technical Specifications in the 3GPP TS 08-series. Technical Specification 3GPP TS 08.02 also contains some information on the placement of transcoders/rate adapters, these being functionally part of the BSS though a degree of fr
40、eedom is allowed in their geographical location. Lastly Technical Specification 3GPP TS 08.02 explains the use of transparent and non transparent signalling information across the interface. The key point is that the majority of call related signalling from the MS is passed in a fairly transparent w
41、ay through the BSS. ETSI 3GPP TS 08.01 version 8.0.1 Release 1999 8 ETSI TS 100 587 V8.0.1 (2002-05) 4.2 Technical Specification 3GPP TS 08.04 Layer 1 - Specification The present document defines the physical layer at the BSS-MSC interface point. The physical interface chosen is a 2Mbits/s (32*64kbi
42、ts/s) interface according to the standard CCITT recommendations. The speech coding called up in the present document is standard A-law, coding of the traffic bit streams for data calls is dealt with in Technical Specifications 3GPP TS 04.21 and 3GPP TS 08.20. 4.3 Technical Specification 3GPP TS 08.0
43、6 Signalling Transport Mechanism - Specification In order to pass the signalling information between BSS and MSC some reliable transport mechanism has to be used. The basis of the transport mechanism is an internationally agreed protocol known as signalling system N0.7. Several services are required
44、 from this protocol but two key requirements are that messages can be transferred between the BSS and MSC without corruption, and secondly that a transaction with a particular mobile can be identified. The correct transfer of messages without corruption is handled by the “Message Transfer Part“ of S
45、S N0.7 and this is documented in Technical Specification 3GPP TS 08.06 which is an exceptions document to the CCITT specification. The subset so formed is designed so that it is compatible with a “full“ MTP such as might be provided at an MSC. The identification of the transaction involved implies s
46、ome form of logical connection. This is achieved by using the signalling connection control part (SCCP) of SS N0.7. Again a minimum subset is formed in order to ease implementation. 4.4 Technical Specification 3GPP TS 08.08 Layer 3 Specification In the present document the application parts are desc
47、ribed. There are two currently identified in the BSS to MSC interface protocol, these are the: - BSSOMAP; - BSSAP. The BSSAP is further subdivided into two subprotocols, the BSSMAP and the DTAP. The BSSMAP and DTAP are fully defined, the BSSOMAP is only supported in terms of a signalling transport a
48、bility. The DTAP text is split between Technical Specifications 3GPP TS 08.06 and 3GPP TS 08.08 but the text in 3GPP TS 08.08 defies which layer 3 air interface messages are passed transparently through the BSS and which are analysed at the BSS. The BSSMAP (base station system management application
49、 part) is that part of the protocol responsible for all aspects of the radio resource handling at the BSS. The text is structured as a set of procedures which are defied separately and can be employed as felt appropriate by the operator/manufacturer to meet the requirements of the application in which it is being used. The procedures themselves can be driven in different modes depending upon the input parameters received from the MSC or sent from the OMC. The BSSOMAP (base station system operation and maintenance application part) supports all of the O and M co
