tion management (CM) and LCM of NSIs and NSSIs, specifically: a list of operations and notifications ("Component A") is defined for the provisioning management service for the NSI and NSSI as well as associated NFs; information models ("Component B") (alternatively called NRM), are defined for NSI and NSSI, as we describe below, see also 3GPP TS 28.541 for details. In the case when an NF is shared between NSIs (NSSIs) there is a need to specify how the NF resources are shared. For this, slicing-related parameters (e.g. RRM policy attributes for NG-RAN) were specified in the provisioning of particular NFs. One example of LCM is the NSI creation procedure, illustrated using the example of the slicing management deployment in Figure 6.5.6: 3GPP management system Monitoring algorithm Decision (RAN) Figure 6.5.7 Centralized SON solution (Source: Reproduced by permission of © 3GPP). 6 Enabling Technologies The consumer (e.g. SON application) activates the allocateNs operation on the NSMF; the activation operation carries the parameters that specify targeted NSI properties, such as service profile parameters. The NSMF determines the NSSIs to be created, such as CN NSSI and RAN NSSI, and activates the allocateNssi operations on the CN NFMF and RAN NFMF to incorporate the needed NFs into the corresponding NSSIs. Additionally, the NSMF calls the transport network NSSMF to establish the topology of the NSI and NSSIs and configure the links in-between. The CN NSSMF and RAN NSSMF determine the configuration parameters for the NFs to be assigned to the corresponding NSSIs and perform the configuration, with or without CN NFMF and RAN NFMF. Furthermore, the TN NSSMF configures the elements of the transport network in accordance with the transport network-related parameters received. 6.5.8.4 NSI and NSSI Information Models (NRMs) The NSI information model (NRM) defined in 3GPP TS 28.541 contains the following essen- tial parts: The list of NSSIs that belong to the NSI, e.g. 5GC NSSI and NG-RAN NSSI; The list of service profiles
