A method performed by an operations administration and management (OAM) apparatus includes acting as a Management Data Analytics Function (MDAF) in a network. The network includes a plurality of network functions (NFs). Acting as the MDAF includes: collecting management data and network data from the network, analysing the management data and the network data, and providing a receiving entity with management data analytics service information based on the analysis of the management data and the network data.

Network data analytics for OAM

A method is performed by a user equipment (UE). The method includes transmitting, to a network, a message for registration of the UE, the message having single network slice selection assistance information (S-NSSAI) that is configured to be added to at least one allowed network slice selection assistance information (NSSAI) after an authentication at an access and mobility management function (AMF). The method also includes receiving, from the AMF, a registration accept message having the at least one allowed NSSAI that includes the S-NSSAI for which the authentication has been completed.

Isolated network slice selection

A method performed by a network node includes receiving a service request for requesting a communication for a user equipment (UE). The service request includes information identifying a service type associated with the requested communication. It is determined whether to reject the service request based on the service type associated with the requested communication.

Service types and congestion control

A core network node for mobility management includes a means for transmitting information related to expected mobility of user equipment, UE, to an access network node.

RRC inactive state optimization

A method is performed by a user equipment (UE). The method includes transmitting, to a network, a message for registration of the UE. The message comprises information related to one or more network slices that are not compatible with at least one allowed network slice.
