Abstract: The disclosure is addressing the 3GPP and GSMA requirements for compatibility restrictions between certain network slices. It proposes solutions for management, control and enforcement of the constraints for simultaneous usage of certain network slices in the UE (3) and in the network. This allows for different level of isolation between the network slices leading to improved security and integrity in the data exchange.

Abstract: A Network Data Analytics Function (NWDAF) for 5G networks is disclosed. A higher granularity of the load level information from the NWDAF is proposed. Also proposed are new ways to utilise the services provided by the NWDAF for other Network Functions (NF) like Network Repository Function (NRF), Access and Mobility Management Function (AMF), Session Management Function (SMF), Policy Control Function (PCF), and Network Slice Selection Function (NSSF).

Abstract: The disclosure proposes solutions for network slice quota monitoring and management. It allows the Service Provider to subscribe with the 3GPP mobile network for network slice quota status notifications and retrieval and/or allows the Service Provider to allocate the initial network slice quota based on SLA (Service Level Agreement), to top-up or cut-down the allocated network slice quota when need and to re-balance it between network slices or between mobile networks.

Abstract: 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.

Abstract: An object of the present disclosure is to provide an access network node, a user equipment, a network function node and a control method capable of steering a UE in connected mode. In one example aspect, a control method for an access network node includes: receiving, from a network function node for mobility management, at least one first network slice information, each of which is different from a second network slice information being used for a Protocol Data Unit, PDU, session with a user equipment, UE; and performing a redirection procedure for the UE from a first cell to a second cell which supports one of the at least one first network slice information in a case where the second network slice information is not available in the first cell.

Abstract: 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.
