Abstract
In one embodiment if a UE is performing minimizing drive test (MDT) measurements and a radio link failure (RLF) occurs the UE may add MDT measurement information to an RLF message to the network. In effect the UE piggy-backs MDT information in the RLF report and in so doing provides greater flexibility to UEs reporting MDT information and more robust reporting. In another embodiment the UE detects that no allowed reporting channel to report MDT measurement information exists stores the MDT information and after detecting that allowed reporting channel exists initiates establishment of a radio link with the radio communications network during which the UE informs the network using an availability indicator that the UE has stored unreported MDT measurement information to be reported to the radio communications network.
