For the purposes of the present document, the terms and definitions given in 3GPP TS 32.101 , 3GPP TS 32.102 , 3GPP TS 32.150  and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TS 32.101 , TS 32.102 , TS 32.150  and TR 21.905 , in that order.
Target: Target provides a clear basis for assessing performance of self-optimization functions. Targets need to be carefully specified in terms of a series of performance measurements and/or KPIs, which can be specific, 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 different 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.
