摘要： 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.

摘要： 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.

摘要： 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).

摘要： A method for a User Equipment (UE) (500) comprises performing registration procedure to 5G System (5GS); receiving at least one of area restriction related information indicating at least one of allowed area and not allowed area, wherein the area restriction related information is at least one of per Single Network Slice Selection Assistance Information (S-NSSAI) basis, per Access Point Name (APN) basis, and per S-NSSAI and APN basis; and determining whether or not to transmit a Protocol Data Unit (PDU) session related signaling based on the area information; wherein the UE (500) transmits the PDU session related signaling when the UE (500) enters Tracking Area (TA) present in the allowed area or when the UE (500) does not enter TA present in the not allowed area.
