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.

Measurement Configuration is also done as part of normal attach procedure. This is required to get measurement report from UE and take corrective action (may be handover) to provide services continuously. Event A1 and A2 are sent by UE regarding serving cell power strength. Event A1 when UE observes signal better than configured threshold and A2 when UE observes signal less than the configured threshold.

1.> During the UL Resource Allocations to ue
2.> During HO to Intra LTE IntraCell HO(Interfrequency OR Intrafrequency) and Intra LTEInter Cell.
3.> Reconfiguration Message after RRC ReEstablishment.

Also during Measurement Gap Configuration during IFHO and IRAT HO

When does eNodeB comes to know that UE wants to do an IRAT handover in the live network?
Or, eNodeB always sends the measurement gap config info in the RRC connection reconfiguration message which has the measconfig IE?

Without knowing the measurement gap configuration, how does the UE perform inter frequency measurements?
Is it something like, the NodeB sends the meas gap config info to UE after succesful attach?Because UE needs to measure other frequency cells both during idle mode and connected mode.
Please clarify.
