22、 which a user accesses by a standard set of interfaces at a MS. The MS is connected to the PLMN fixed infrastructure via a radio path to a base station, as shown in figure 1. 1.2 Basic interfaces for user access for a GSM PLMN The MS-BSS interface on this radio path is specified in the 04-series of
23、Technical Specifications in such a way as to permit user and network technologies and configurations to evolve separately. MY1 T-t-r-f radio path infrastructure interface (04 series) Figure 1 : Basic interfaces for user access for a GSM PLMN 1.3 Principles and procedures for the man-machine interfac
24、e (MMI) to the MS The principles and procedures for the man-machine interface (MMI) to the MS are described in GSM 02.30. The user may also use standard terminal interfaces within the MS. The reference configuration for the access is described in GSM 04.02. 2 Interface applications Figure 2 shows so
25、me examples of the application of GSM MS-BSS interfaces. The following cases are shown: i) access of simple handportable or vehicle mounted MSs; i) iii) access of an MS with multiple terminal equipment installation; access of a mobile PBX or LAN; In addition, the figure identifies internetwork inter
26、faces for connections to: iv) land-line ISDN networks; v) dedicated service networks.

GSM network Figure 2: Examples of GSM interfaces 3 Interface technical specification objectives MS-BSS interface Technical Specifications should allow: i) i) different types of MSs and terminal equipment to use the sa
28、me standard interface; portability of MSs within the system area of the GSM system; iii) iv) v) separate evolution of both MSs and network equipment technologies and configurations; calls to a terminal using the same code (call number) no matter in what country it is actually located; connections of
29、 an MS to the ISDN network so that only the radio channel capacity and the ISDN protocol are limiting factors. 4 Interface characteristics The MS-BSS interface is specified by a comprehensive set of characteristics, including: i) channel structures and access capabilities; i) user-network (MS-BSS) p
30、rotocols; iii) maintenance and operation characteristics; iv) performance characteristics; v) service characteristics. - _ STDmETSI GSM O4-OL-ENGL L79b m 3400855 0159234 b07 m Page 10 GSM 04.01 version 5.0.0: November 1996 5 Interface capabilities I In addition to the multiservice capability, the GS
31、M MS-BSS interface may allow for capabilities such as the following: i) multidrop and other multiple terminal arrangements; i) choice of information bit rate, circuit or packet switching mode, layer 2 coding method, etc ., on a call-by-call or other basis (e.g. semipermanent, or subscription time op
32、tion), over the same interface according to the users need; iii) capability for compatibility checking in order to check whether calling and called terminals can communicate with each other. 6 Technical Specifications on GSM MS-BSS interfaces 6.1 Reference configurations I i The reference configurat
33、ions for the GSM MS-BSS interface define the terminology for various reference points. GSM 04.02 contains the GSM PLMN access reference configuration. l l Channel structures and access capabilities 6.2 GSM 04.03 defines the channel structures and access capabilities for the MS-BSS interface. A disti
34、nction is necessary between the logical channel structure supported by the interface and the access capability supported by the radio path of the system. 6.3 MS-BSS interface as defined in GSM 04.04 through GSM 04.12 The MS-BSS interface as defined in GSM 04.04 through GSM 04.12 is applicable to a w
35、ide range of situations. 7 Protocol modelling principles 7.1 The signalling protocols on the MS-BSS Interface are specified using the concepts of the reference model of Open System Interconnection (OSI) given in CCIlT Recommendations X.200 and X.210. Signalling protocols on the MS-BSS Interface 7.2
36、The basic structuring technique in the OS1 reference model The basic structuring technique in the OS1 reference model is layering. According to this technique, communication among application processes is viewed as being logically partitioned into an ordered set of layers represented in a vertical s
37、equence as shown in figure 3. Highest layer 1 (N + 1)-layer (N)-layer (N - 1)-layer I Lowest layer I Figure 3: Layering Entities exist in each layer. Entities in the same layer, but in different systems which must exchange information to achieve a common objective are called “peer entities”. Entitie
38、s in adjacent layers interact through their common boundary. The services provided by the (N + 1)-layer are the combination of the services and functions provided by the (N)-layer and all layers below the (N)-layer. - STD-ETSI GSM 04.OL-ENGL L7Sb U 3400855 0357235 545 m Page 11 GSM 04.01 version 5.0
39、.0: November 1996 Request Indication I I I Confirm t Management functions may also be required. They may include functions which are common for several layers and are not supported by the services provided by a specific layer. Examples of such functions are error reporting, status reporting and mana
40、gement of the operation of certain layers. Such management functions do not require that peer-to-peer messages are sent across the MS-BSS interface. Response 1 i 7.3 For signalling on the MS-BSS interface three layers are required as shown in figure 4. Signalling on the MS-BSS interface Layer 3 t Da
41、ta link layer Physical layer Figure 4: Layering on the MS-BSS interface The layers are: - PHYSICAL LAYER which corresponds to the lowest layer. The functions and protocols of the physical layer are defined in GSM 04.04. DATA LINK LAYER. The functions and protocols of the data link layer are defined
42、in GSM 04.05 and GSM 04.06. - - LAYER 3. The functions and protocols of layer 3 are defined in GSM 04.07, GSM 04.08, GSM 04.10, GSM 04.11 and GSM 04.12. 7.4 Service primitives Layer-to-layer interactions are specified in terms of service primitives. The primitives represent, in an abstract way, the
43、logical exchange of information and control between adjacent layers. They do not specify or constrain implementation. Primitives are also used to describe information exchange between layers and the mobile management entity. Figure 5: Primitive action sequence for peer-to-peer communication The REQU
44、EST primitive type is used when a higher layer is requesting a service from the next lower layer. STD-ETSI GSM OLi-01-ENGL 199b 3LiOO855 OL5923b 481 = I Page 12 GSM 04.01 version 5.0.0: November 1996 The INDICATION primitive type is used by a layer providing a service to notify the next higher layer
45、 of activities related to the primitive type REQUEST. The RESPONSE primitive type is used by a layer to acknowledge receipt, from a lower layer, of the primitive type INDICATION. The CONFIRM primitive type is used by the layer providing the requested service to confirm that the activity has been completed.
