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: A method for operating a WiMAX femtocell base station, wherein the femtocell base station has an active operational mode, in which the radio interface subsystem of the femtocell base station is fully power supplied, is characterized in that a power saving mode with reduced radio interface activity is provided, wherein the femtocell base station is enabled to transit between the active operation mode and the power saving mode. Furthermore, a corresponding femtocell base station for deployment in a WiMAX network is disclosed.

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: The current disclosure proposes per UE customization of the UE DRX/eDRX and PSM based on the analytical results from NWDAF. It also proposes a new UE policy element for UE analytics reporting—UE Analytics Reporting Policy that is a set of reporting rules and is defined by the PCF based on analytical results from NWDAF. The UEARP then is delivered or updated in the UE during registration.

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.
