3.1 Definitions

For the purposes of the present document, the terms and definitions 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].

network slice: a logical network that provides specific network capabilities and network characteristics, supporting various service properties for network slice customers.

NOTE 1: NetworkSlice Information Object Class (IOC) (refer to TS 28.541 [6]) is used to model network slice.

NOTE 2: Represent network slice defined in TS 23.501 [3] with added service properties.

NetworkSlice instance: A Managed Object Instance (MOI) of NetworkSlice IOC.

NOTE 3: NetworkSlice instance represents service view of a network slice which exposes the root NetworkSliceSubnet instance .

network slice subnet: a representation of a set of network functions and the associated resources (e.g. compute, storage and networking resources) supporting network slice.

NOTE 4: NetworkSliceSubnet IOC (refer to TS 28.541 [x]) is used to model network slice subnet which may include core network functions and/or RAN network functions and/or other network slice subnets. The network slice instance defined in TS 23.501 [3] can be reflected via the NetworkSliceSubnet IOC and the allocated resources.

NetworkSliceSubnet instance: A Managed Object Instance (MOI) of NetworkSliceSubnet IOC.

Service Level Specification (SLS) : a set of service level requirements associated with a Service Level Agreement (SLA) to be satisfied by a network slice.

Note: Void
