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 granularityContinue reading “Quality of Service (QoS) in 5G Network”

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 forContinue reading “Dynamic Spectrum Sharing (DSS) – Coexistence of 5G NR with 4G LTE”

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 toContinue reading “5G Identities :Globally Unique Temporary UE Identity (5G-GUTI)”

5G Identifier SUPI and SUCI

Subscription Permanent Identifier (SUPI) A SUPI is a 5G globally unique Subscription Permanent Identifier (SUPI) allocated to each subscriber and defined in 3GPP specification TS 23.501. The SUPI value is provisioned in USIM and UDM/UDR function in 5G Core. Subscription Concealed Identifier (SUCI) Subscription Concealed Identier (SUCI) is a privacy preserving identifier containing the concealedContinue reading “5G Identifier SUPI and SUCI”

Open RAN Architecture

Dear Friends Thanks for watching 5G sessions on my you tube channel.  Now I have recorded series of sessions on Open RAN. Part 3   In part 1 I have covered basic concepts of Traditional RAN, Virtual RAN and Open RAN. In Part 2 , I have covered CRAN or Centralised RAN / Cloud RAN /Continue reading “Open RAN Architecture”
