In today’s device validation and field testing, it’s important to verify:
Whether the UE supports EN-DC / NR (5G NSA)
Which NR bands are supported
What Paging Cycle is configured in the device
How these parameters appear in live OTA logs
In this analysis using QXDM:
From UE Capability Information, we can verify:
en-DC-r15 supported
supportedBandListEN-DC-r15
NR band combinations
LTE Category & RF parameters
This confirms whether the device is NR capable and supports EN-DC (NSA 5G).
From SIB / RRC messages, we can check:
Paging cycle configuration
Default paging parameters
DRX related configuration
System Information Blocks (SIB1/SIB2)
By decoding OTA logs step-by-step:
RRCConnectionRequest
SecurityModeCommand
UE Capability Exchange
RRC Reconfiguration
We can clearly determine device capability and network configuration.
This type of deep log analysis is very useful for:
GCF/PTCRB validation
Carrier Acceptance Testing
Field Issue Debugging
Throughput & EN-DC verification
QXDM log analysis gives complete visibility into how the UE negotiates capabilities and how the network configures paging and radio behavior.
