Description (partial)

Symptom:
The UE Radio Capability IE size in UE Capability Info Indication message size is close to the maximum permitted message size on S1-AP. When this IE is encoded in Initial Context Setup Response message the message size exceeds 6144 bytes (max permitted size). At MME APP the S1AP message size is checked against the max permitted size and so the Initial Context Setup Response message is dropped and not sent to UE.

Conditions:
The UE Radio Capability IE size in UE Capability Info Indication message size is close to the maximum size permitted on the S1-AP interface.
