MN Initiated SN Release (Data forwarding related)

+1 vote
511 views

I have a question related to MN Initiated SN Release. (Mainly from 5g E1 interface perspective)
I think, it is similar to LTE case, but the SN in case of LTE is sungle entity.

On sending the SgNBReleaseRequest (which has the data forwarding information), the SN, entity starts to buffer the data (both UL and DL).
And it sends the SgNBReleaseRequestAck back to MN. MN then uses this information to send the "RRCConnectionReconfiguration" to the UE with that info.
My question is, how does the SN, know till how long it needs to buffer the data. And initiate the SN Status Transfer and Data forwarding to the MN.
Another Q is, if it is stopped the Buffering, how does it detect the end Marker packet from the Core?

What is purpose of having feedback at Xn(user plane) during Dual Connectivity(SeNB -> MeNB)

In Release14/15 for to support Dual Connectivity Xn user plane interface was introduced.
which is similar to S5(PGW <=> SGW)/S1(eNB <=> SGW) interface means GTP-u over UDP.

In 36.425 Xn has status report which lost packet range with start and last packet. What is the significance of having those in status report?

Does MeNB Xn has to re-transmit lost packets over Xu?
Or Also in Xn status report we have "Highest successful delivered PDCP seqence number", how SeNB Xn will get the PDCP sequence number while sending the status report?

If SeNB Xn has to send feedback report at interval it has to send?

Could anyone please clarify the above queries.

Dual connectivity related specs in LTE?

While digging into 5G NR dual connectivity, ( and as you are aware that it is based on LTE dual connectivity). I want to learn a bit about how LTE put the foundation for this feature to come towards 5g.

I want to read the LTE architecture specs related to dual connectivity.
I donot have much RAN background in LTE. Could somebody from this background give me some quick hints, to look into which 3gpp TS or TR to understand some basics.

Btw there is 3GPP TS 36.401 doesnot have much info it looks like.

LTE: How the uplink and downlink data flow through indirect data forwarding tunnels in S1- handover ?

I went through the call flow diagram that is shown in 23.401 specification and tried to understand data flow (down link and up link both) through indirect data tunnels. I was bit confused that's why post my query here.
