When eNB includes DedicatedinfoNASlist IE in RRC Connection reconfiguration message?

Question

Is their any triggering point ENB has to send Measurement consfiguration to UE.

Generally measurement configuration will come in RRC Reconfiguration message.At intall attach procedure ENB will send RRC Connection Reconfiguration message to send SRB2 and DRB configuration.

So,My question what is the triggering point to send Measurement configuration.

Answer 1

Answer 2

Suppose while sending RRC Reconfiguration message if eNB received/have any NAS info from MME then that NAS message will go as DedicatedInfoNASList it is drb specific.

Example -

1> While sending Attach accept message DedicatedInfoNASList will contain a nas message of (Attach accept + Activate default EPS bearer context request )
2> Similarly when we are going for creating a dedicated bearer then DedicatedInfoNASList will contain Activate Dedicated EPS Bearer Context Request message.

And all these message will be go as transparent container for RRC but it will be forwarded to NAS layer after Ue receives RRC Reconfiguration message.
