3.1 Terms

For the purposes of the present document, the terms given in 3GPP TR 21.905 [1] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 [1].

Centralized SON (C-SON): SON solution where SON algorithms are executed in the 3GPP management system. Centralized SON has two variants:

– Cross Domain-Centralized SON: SON solution where SON algorithms are executed in the 3GPP Cross Domain layer.

– Domain-Centralized SON: SON solution where SON algorithms are executed in the Domain layer.

Distributed SON (D-SON): SON solution where SON algorithms are executed in the Network Function layer.

Hybrid SON: SON solution where SON algorithms are executed at two or more of the following layers: NF layer or Domain layer or 3GPP Cross Domain layer.

Searchlist: list of frequencies and supporting information to be used for neighbour cell measurements, which contains entries for NG-RAN and supported IRATs.
