1. A method for a user equipment (UE) to report measurement information to a radio communications network, the UE performing the steps comprising:

  • performing minimizing drive test (MDT) measurements for report to the radio communications network;

    detecting a failure to report MDT measurement information;

    in response to detecting the failure to report the MDT measurement information, storing unreported MDT measurement information;

    detecting a radio link failure;

    transmitting a connection reestablishment request message to the radio communications network;

    receiving a connection reestablishment message from the radio communications network responding to the transmitted connection reestablishment request message;

    in response to the connection reestablishment message, transmitting a connection reestablishment confirmation message to the radio communications network, wherein the connection reestablishment confirmation message includes an indication that stored unreported MDT measurement information is available for transmission;

    receiving an information request message from the radio communications network, wherein the information request message includes a report request indicator;

    detecting whether the report request indicator in the received information request message is set; and

    in response to detecting that the report request indicator is set, transmitting a radio link failure (RLF) message that also includes at least some of the stored unreported MDT measurement information to the radio communications network.
