W 3404583 0320757 4bT Page 7 GSM 12.22 version 4.0.1 1 GENERAL 1.1 SCOPE To ensure management of different manufacturers BTSs from the OMC through the BSC in a standardised way, this BSC interworking specification is needed to relate th

24、e OMC-BSC interface (23) as specified in GSM 12.20 and the BSC-BTS interface (A-bis Qx) as specified in GSM 12.21. In GSM 12.01 it is required that the BSC performs the Mediation Function between the OMC and the BTS. This specification defines the requirements for this Mediation Function. 1.2 STRUCT

25、URE OF THIS SPECIFICATION This specification is structured as follows 1. General 2. Common interworking aspects 3. Specific interworking aspects 4. Related A-bis structured procedures Annex 1. Some interworking issues Section 1 contains the general overview of this specification. Section 2 describes

26、 the aspects common to all the managed object classes that cause interworking between the Q3 and Qx interfaces. Objects and their naming and addressing on the OMC-BSC and A- bis Ox interfaces are briefly described. General requirements for Q3/Qx interworking for CMIP operations including error handl

27、ing are given. Q3/Qx interworking of general functions, .e., state management and alarm reporting, are also specified. Section 3 specifies the aspects, specific to each object class, that cause interworking. This section contains the requirements on mapping between the GSM 12.20 specified and GSM 12

28、.21 specified objects, their attributes, and object specific interworking procedures for different CMIP operations. Section 4 defines the A-bis structured procedures used in section 3. Annex 1 describes the structured procedures at a high level which are used in managing the BTS from the OMC. 1.3 IN

29、TER WORKING TASKS Figure l/GSM 12.22 illustrates differences between Q3 and A-bis Qx interfaces and the object models in the BSC and the BTS.

30、ng of information models. In the A-bis interface, layers 1 and 2 are common with telecommunication signalling specified in GSM 08.5X. Network management messages and procedures on the A-bis interface are based on the layer 3 transport mechanism specified in GSM 12.21 and are consistent with the tele

31、communications signalling on layers 3 as specified in GSM 08.58. The protocol profiles for the Q3 interface are specified in GSM 12.01. For network management purposes, the BSC is responsible for the following interworking tasks: - bi-directional protocol conversion so as to provide mapping between

32、Q3 and A-bis Qx interfaces which consists of mapping of GSM 12.20 objects onto GSM 12.21 objects, mapping of CMIS services onto GSM 12.21 procedures and association of GSM 12.20 attributes to GSM 12.21 attributes; management of interworking functions activated by the OMC and terminated within the BT

33、S and vice versa; handling of interworking errors, .e., reporting errors in case of failure in interworking procedures. - - Note The functions activated by the OMC and terminated within the BSC or functions activated by the BTS and terminated within the BSC are not specified here. This applies also

34、to the vice versa situations. 1.4 ABBREVIATIONS Definitions and abbreviations used in this ETS are listed in GSM 01.04. 1.5 NORMATIVE REFERENCES CCIlT Recommendation X.71 O: Common Management Information Service Definition for CCIlT Applications CCIT Recommendation X.711: Common Management Informati

39、 Object Classes Q3 and A-bis Qx interfaces use different object models. The specification of the interworking procedures between these interfaces requires mapping the object classes and instances between the Q3 interface and the A-bis Qx interface and vice versa. The following table contains BTS rel

40、ated object classes specified in GSM 12.20 and the corresponding object classes specified in GSM 12.21. Table l/GSM 12.22. BTS related object classes in GSM 12.20 and GSM 12.21. I frequencyHoppingSystem 1 lkhannel I I channel I Channel I I IapdLink I 2) I Note 1: GSM 12.21 doesnt specify the frequen

41、cy hopping system as an object class. The corresponding information is included in the attributes of the channel class. Note 2: The information about the signalling links of the BTS side (PCM port numbers and timeslots in the BIS) is included in the attributes of Site Manager, BTS and Baseband Trans

42、ceiver classes. In GSM 12.20 the corresponding object classes have references to LAPD links which are either O&M links (in Site Manager, bts or basebandTransceiver) or telecom signalling links (only to basebandTransceiver). 2.1.2 Addressing Objects at the BTS Site and Handling Different BTS Configur

43、ations The BCF (Base Control Function) mentioned in GSM 08.52 and GSM 08.56 is the agent at the BTS end of the A-bis Qx interface. There could be one or more of these agents at the site and the GSM 12.21 objects and attributes that each agent can manage depend on the implementation. Each agent is co

44、nnected to the manager at the BSC via a LAPD link which is identified by a physical link address (.e. PCM circuit and (sub)timeslot), TE1 (Terminal Endpoint Identifier) and SAPI (Service Access Point Identifier). In order to address the various BTS objects over the A-bis Qx interface it is required

45、that the BSC contain associations between BTS related objects defined in GSM 12.20 and the agents (.e. O&M links) that manage the corresponding GSM 12.21 objects at the BTS site. The procedures that relate to the A-bis interface management are optional in GSM 12.21 and therefore not all the BTSs hav

46、e to support them. However, it is required that these are implemented in the BSC so that it can support all the BTS implementations that are made according to GSM 12.21. In this case the BSC must have the information per ,each BTS whether the A-bis interface management option is supported or not. m

The Correspondi

48、ng physical resource may or may not exist at the BTS site. Normally the initialisation of the physical resource via A-bis Qx interface will be started immediately ater the creation if the corresponding physical resource at the BTS site has been installed. Initialisation might include several steps,

49、such as, setting up O&M (and telecommunications) signalling links, downloading and activation of the software, setting various O&M attributes by GSM 12.21 messages and setting the system information to be broadcasted from the BTS by GSM 08.58 procedures. Some of these steps are not relevant for some object classes. Object creation to the BSC should be possible before any resources are installed at the BTS site. If the resource for the object to be created has not been installed at the BTS site, the agent at the BTS site wont respond or it will respond with a NAC
