20、 general, provides the operator with the ability to perform effective network management as the PLMN evolves. CM is initiated by the operator in various network elements of the PLMN to meet the operator objectives. CM actions may be requested as part of an implementation programme (ag. additions and
21、 deletions), as part of an optirnication programme (ag. modifications), and to maintain the overall Quality of Service. The CM actions are initiated either as a direct action on a network element of the PLMN or as part of a complex procedure involving actions on many network elements. Chapter 4 will
22、 provide a brief background of CM while Chapter 5 will explain CM services available to the operator. Chapter 6 will break these services down into individual CM functions which will support the defined services. Chapter 7 describes the application of these services and functions to the BSS NE in a
23、GSM PLMN. In Annex A there are informative examples to illustrate the combination of CM functions to completed scenarios.

24、tial emphasis on the BSS management. This is described from a management perspective being decomposed into constituent functionalities, which in turn will allow the construction of a management object model using the object oriented paradigm to support open systems management (see 14). The specifica
25、tion will follow the methodology described in lo. GSM 12.06 defines a set of controls to be employed to effect Set-up and changes to a PLMN, in such a way that operational capability, network integrity and inter working co-operation are ensured. In this way, GSM 12.06 describes the interface behavio
26、ur for the management of PLMN NEs in the context of the described management environment. The context is described for both the OS and NE functionality. The standardisation of specific controls is outside of the scope of this specification. 2 Nonnative references This ETS incorporates by dated or un

Network Element: is a discrete telecommunications entity which can be managed over a specific interface e.g. the BSS. Network Resource: is a component of a Net
34、work Element which can be identified as a discrete separate unit e.g. BSC, BTS or TRX . Operator: is either * * a human being controlling and managing the network ; or, a company running a network (the PLMN operator). Optimisation: of the network is each update or modification to improve the network

Reconfiguration: is the re-arrangement of the parts, hardware and/or software that make up the PLMN. A re-configuration can be of the parts of a single NE or can be the re-arrangement of the NE

40、ses can be described which represent different degrees of stability. Once the first stage is over the system will cycle between the second and the third phase. This is known as the network life-cycle and includes: I. the PLMN will be installed and put into service; 2. the PLMN reaches certain stabil
41、ity and is only modified (dynamically) to satisfy short term requirements, e.g. by (dynamic) re-configuration of resources or parameter modification; the stable state of a PLMN cannot be regarded as the final one because each equipment or SW modification will let the PLMN progress to an unstable sta
42、te and require optimisation actions again; 3. the PLMN is being adjusted to meet the long term requirements of the network operator and the customer, e.g. with regard to performance, capacity and customer satisfaction through the enhancement of the network or equipment upgrade. During these phases,
43、the operators will require adequate management fundions to perform the necessary tasks. 4.1.1 Installing a PLMN When a PLMN is installed and initialised for the first time, all NEs need to be introduced to the OS, the data for initialisation and SW for proper functioning need to be provided. All the
44、se actions are carried out to create NEs and to initialise them. 4.1.2 Operating a PLMN _- Whilst in service, the operator will need to react to short term incidents such as traffic load requirements which are different from the current network capabilities, NEs/NRs need to be re-configured and para
45、meters need to be adapted to follow these day-to-day requirements. 4.1.3 Growingpntning a PLMN As the PLMN grows and matures new equipment is installed and understanding of system behaviour increases. Subscriber requirementshvishes may demand that operators modify their system. In addition. manufact
46、urers improve the infrastructure components and add features to their products hence the operator will start modifying the PLMN to proM from these modifications and to improve subscriber satisfaction. Additionally, the PLMN configuration will be modified (.e. it will be updated or upgraded) to cope
47、with a need for increasing or decreasing network capacity. These actions are carried out for the long term strategy of the operators to optimise the network. 4.1 3.1 System update Whenever the PLMN needs to be improved for reasons of reducing failures, the system will be updated. In this case SW or
48、equipment will be replaced without adding new functionaties or resources to the network. The basic function required is: the modification of existing SW/equipment; it may be necessary to introduce a different set of data to cope with the modified SW/equipment. For system update the network shall not
49、 be disturbed in its function until the required modification is activated. This requires mechanisms to a- do SW/data downloading in parallel with on-going traffic; * isolate the affected NEs/NRs from traffic before the actual modificatiorl is done. 4.1.3.2 System up-grade System up-grade may affect all areas of PLMN activities and can be described as enhancements, whereby either new features or new facilities are implemented. Also extensions, reductions or further replications of existing facilities are covered by this CM aspect
