Targets need to be carefully specified in terms of a series of performance measurements and/or KPIs, which can be specific,

41、and which can be used also to identify problems. A target should be expressed in terms of a specific value or specific value range. The present document does not specify the specific value or desired value range of each target since those should be set by operators according to their policy and diff

42、erent network situation. Trigger condition: The condition at which self-optimization should be triggered. Different self-optimization algorithms may have different trigger conditions for achieving same objectives and targets. 3.2 Abbreviations For the purposes of the present document, the following

46、ill be made according to the optimization algorithms. Finally, corrective actions on the affected network node(s) will be triggered automatically or manually when necessary. IRPManager should be able to control the self-optimization procedures according to the operator“s objectives and targets. The

47、following diagram is illustrated how the self-optimization functionality works: ETSI ETSI TS 128 627 V13.2.0 (2016-04)83GPP TS 28.627 version 13.2.0 Release 13Figure 4-1 Logical view of self-optimization procedure The self-optimization functionality working procedure could be interpreted logically a

48、s following: 1. The self-optimization functionality keeps monitoring input data according to the operator“s objectives and targets. 2. Whenever the objectives and targets are not met, optimization algorithms will be triggered. 3. Corrective actions are provided and executed. 4. Then the self-optimiz

49、ation functionality evaluates the result of the executed corrective actions. Loop: Keep Monitoring Is system status better after the corrective actions execution? Analyse input data with Optimization Algorithms Execute corrective actions Monitor input data One time Self-optimization procedure ends Fallback may be needed to reverse the system to the previous status, which is before the corrective actions executed. Yes No Meet the targets? Yes No ETSI ETSI TS 128 627 V13.2.0 (2016-04)93GPP TS 28.627 version 13.2.0 Release 13a) If the
