Study on application architecture for the Future Railway Mobile Communication System (FRMCS); Stage 2 Based on 3GPP SA2 TS23.501, SA5 has defined different management aspects for network slices in TR28.801 as listed below: 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.

Study on system impacts of extended Discontinuous Reception (DRX) cycle for power consumption optimization Need to keep your conversation under the radar? With direct messaging or team text chat, you can get the message across without the noise. Quality of Service (QoS) and policy aspects of 3GPP - Wirless Local Area Network (WLAN) interworking Identification 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: Study on Multimedia Broadcast and Multicast Service (MBMS) usage for mission critical communication services
