Product Information

Selective disabling of User Equipment (UE) capabilities; Report on technical options and conclusions customized Applications for Mobile network Enhanced Logic (CAMEL) - IP Multimedia System (IMS) interworking; Stage 2 Network Slice : A logical network that provides specific network capabilities and network characteristics.

Feasibility study for enhancement of radio performance for Voice over IP Multimedia Subsystem (VoIMS); Report on technical options and conclusions IP-Short-Message-Gateway (IP-SM-GW) enhancements for interworking with Open Mobile Alliance (OMA) Converged IP Messaging (CPM) Study on Stage 2 aspects of Optimised Service Charging and Allocation of Resources (OSCAR) in the IP Multimedia Subsystem (IMS) whilst roamingIdentification of a Network Slice is done via the Single Network Slice Selection Assistance Information (S-NSSAI). The NSSAI (Network Slice Selection Assistance Information) is a collection of S-NSSAIs. Currently 3GPP allows up to eight (8) S-NSSAIs in the NSSAI sent in signaling messages between the UE and the Network. This means a single UE may be served by at most eight Network Slices at a time. The S-NSSAI signaled by the UE to the network, assists the network in selecting a particular Network Slice instance. An S-NSSAI is comprised of: Interworking aspects and migration scenarios for IPv4-based IP Multimedia Subsystem (IMS) implementations Study on Machine-Type Communications (MTC) and other mobile data applications communications enhancements

A Slice Differentiator (SD), which is an optional information that complements the Slice/Service type(s) to differentiate amongst multiple Network Slices of the same Slice/Service type.

Application layer support for Uncrewed Aerial System (UAS); Functional architecture and information flows; Voice Call Continuity (VCC) between Circuit Switched (CS) and IP Multimedia Subsystem (IMS); Stage 2

A Protocol Data Unit (PDU) Session is associated to one S-NSSAI and one DNN (Data Network Name). The establishment of a PDU session within the selected instances-NSSAI is triggered when the AMF receives a Session Management message from UE. The AMF discovers candidate Session Management Functions (SMF) using multiple parameters including the S-NSSAI provided in the UE request and selects the appropriate SMF. The selection of the User Plane Function (UPF) is performed by the SMF and uses the S-NSSAI. The Network Repository Function (NRF) is used for the discovery of the required Network Functions using the selected Network Slice instance – the detailed procedures are specified in 3GPP TS 23.502. The data transmission can take place after a PDU session to a Data Network is established in a Network Slice. The S-NSSAI associated with a PDU Session is provided to the AN, and to the policy and charging entities, to apply slice specific policies.
