TNL QoS

[uchok]

Hello Experts,

I have a dual stack site.
When there was problem with gigabit ethernet link it only affected PS RAB, for RRC and CS are OK.
Is this related to TNL QoS? If yes could someone explain to me how the configuration or what are the MO's.

It's because of the dual stack configuration. Control Plane and CS Services are carried over ATM, HSPA services are carried over IP/Ethernet. At tnlQosClass MO you can configure prefIubUserPlaneTransportOption. Example below:

=================================================================================================================
25503 RncFunction=1,RabHandling=1,TnlDchQosClassProfile=0,TnlQosClass=DchSrbConvStr
=================================================================================================================
TnlQosClassId DchSrbConvStr
aal2QosClass 0 (QOS_CLASS_A)
dscpEgress 18
dscpIngress 18
prefIubUserPlaneTransportOption Struct{2}
>>> 1.atm = 1 (TRUE)
>>> 2.ipv4 = 0 (FALSE)
reservedBy [4] =
>>> reservedBy = RncFunction=1,RabHandling=1,TnlDchQosClassProfile=0,TrafficClass=1
>>> reservedBy = RncFunction=1,RabHandling=1,TnlDchQosClassProfile=0,TrafficClass=2
>>> reservedBy = RncFunction=1,RabHandling=1,TnlDchQosClassProfile=0,TrafficClass=3
>>> reservedBy = RncFunction=1,RabHandling=1,TnlDchQosClassProfile=0,TrafficClass=4
spi -1
userLabel Class_A

So it applied in RNC level? Not per Iub?
And previously if you don't apply this TnlQoS, the control plane goes through ATM, and Userplane (CS & PS) goes through IP, is that correct?

For Iub Dual Stack, by default CP traffic / CS services are carried over ATM and PS services are carried over IP. At RNC you can create a TnlQosClass MO and configure QoS and select the transport option. At TrafficClass MOs (already creates at RNC) you can set the TnlQosClass than you created before.

At MO IubLink you can configure Iub ATM/DS/FullIP. Below is an example for Iub DS.

For the transport option in Iub I already understand.
I'm more curious related to TnlQos, because I believe before there was TnlQoS, Controlplane is using ATM and Userplane (both CS & PS) is using IP, whenever I have IP transmission problem it will only affected high PS drop and Drop call but not accessibility.

Do you have any document regarding TnlQos?

Check file enclosed. I hop those documents would be useful for you.

For Dual Stack Iub, SRB/RRC/Conversational Speech/Conversational Streaming are carried over ATM by default. If you have problems in IP transport, Accesibility and CS services will be OK, only PS services will be affected.
