One question Mr Kumar: Does NSSAAF interact with UDR (in order to get the Subscribed NSSAI) for slice level authentication? Thank you

Thanks for your videos. I have a little diverging question. In 5G, is there still this hexagonal frequency usage plan to avoid interference?
@5Gand6G Жыл бұрын
Freq reuse factor is 1, means same spectrum can be used by neighbour cells. Hexagon coverage is because of radiation pattern and not due to 4G and 5G.

In case of NR Carrier Aggregation for eMBB, the aggregated frequencies should support the same slice for eMBB.Correct? Thank you

In case that UE does not provide requested NSSAI during registration on Serving PLMN or HPLMN then UE will be provisioned with default Configured NSSAI.Correct ?
@5Gand6G Жыл бұрын
During initial registration, NSSAI provided by UE is used by gNB to select AMF serving the requested NSSAI.
@5Gand6G Жыл бұрын
In case UE does not provide, AMF selects default AMF
@5Gand6G Жыл бұрын
During registration response msg to UE, allowed NSSAI is provided back to UE.

Is Nssf or AMF of HPLMN responsible for the mapping of Configured NSSAI to Subscribed NSSAI ?Thank you Mr Kumar

AMF may ask NSSF as required.

i have a question , concerning the difference between the Slice and PDU session ? what are the metrics to evaluate a QoS flow ? how for a subscriber can check that the operator are note violate the requirement in the SLA ?
@5Gand6G8 ай бұрын
1. PDU session is basic pipe for user data flow. 2. Within a PDU session, there will be one default QoS flow and there may be more GBR and or NGBR QoS flow added as required. 3. Slices are end to end division of network resources for a specific service. Point 1 and 2 will be within slice also. 4. I have not seen any metric accessible to user on QoS. If you know it, pl share.

can u give a reference about the concept u mentioned in your video related to how many slices a user can access simultaneously in network slicing.IS this limit is defined by 3GPP standards or by other governing body
@5Gand6G8 ай бұрын
8 slices ...defined by 3GPP

What is the benefit for a Ue of simultaneous registration to more than one slices ? In any case, a Ue can register and use all Allowed s-NSSAIs in a specific TA, without the need of simultaneous registration. Is it correct ? Thank you Mr Kumar
@5Gand6G4 ай бұрын
In the case of RAN Slicing, we have group of slices in a TA, UE can access slices in a group at a time. That group of slices will have common AMF for the specific UE. This needs simultaneously registering in gp of slices.
