Quality of Service (QoS) in 5G Network
The 5G QoS model is based on QoS Flows. The 5G QoS model supports both QoS Flows that require guaranteed flow bit rate (GBR QoS Flows) and QoS Flows that do not require guaranteed flow bit rate (Non-GBR QoS Flows). The 5G QoS model also supports Reflective QoS The QoS Flow is the finest granularity…
Dynamic Spectrum Sharing (DSS) – Coexistence of 5G NR with 4G LTE
5G is the first ever mobile radio system that is designed to use any spectrum from below 1 GHz up to millimetre waves. 5G is also designed to be deployed in licensed, shared and unlicensed spectrum bands. 5G can use Frequency Division Duplex (FDD) technology for paired spectrum and Time Division Duplex (TDD) technology for…
5G Identities :Globally Unique Temporary UE Identity (5G-GUTI)
The AMF shall allocate a 5G Globally Unique Temporary Identifier (5G-GUTI) to the UE that is common to both 3GPP and non-3GPP access. It is possible to use the same 5G-GUTI for accessing 3GPP access and non-3GPP access security context within the AMF for the given UE. An AMF may re-assign a new 5G-GUTI to…
