Abstract: A NWDAF node according to the present disclosure comprises means for receiving, from a network function node, a request for detecting a new application, including an indication having a value “new application analysis”, information for a UE, start and end time for detection and PFD information; means for subscribing, to a SMF node, data collection related to the new application; means for receiving, from a UPF node via the SMF node, the data related to the new application, including DNN, S-NSSAI, and 3-tuple(s); and means for notifying the network function node of an analytic result including the DNN, the S-NSSAI, the 3-tuple(s) to be added to the PFD information, parts of the URL to be matched, a Domain name matching criteria and information about applicable protocol(s), wherein the 3-tuple(s) includes a server side IP address and port number.

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 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: 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: 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.
