Method and system of providing MDT measurement information to a base station in a wireless network environment

A user equipment (UE) for providing minimization of drive test (MDT) measurement information to a base station, the UE comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises a MDT log module, wherein the processor is configured to execute one or more instructions of the MDT log module to cause the UE to:
• receive a UE information request message to transfer logged MDT measurement information;
• determine whether a portion of the logged MDT measurement information is left over with the UE based on a total size of the logged MDT measurement information and a total size of a single packet data convergence protocol (PDCP) service data unit (SDU);
• and
• transmit a UE information response message including a MDT log field indicating that the logged MDT measurement information is available with the UE if the portion of the logged MDT measurement information is left over with the UE,
• wherein the MDT log field is set to TRUE.

A method of providing minimization of drive test (MDT) measurement information to a base station by user equipment (UE), the method comprising:

• indicating an availability of the MDT measurement information and a number of packet data convergence protocol (PDCP) service data units (SDUs) required to transfer all of the MDT measurement information to the base station;
• receiving a UE information request message to transfer the MDT measurement information in response to the indication;
• transmitting a UE information response message including at least a portion of the MDT measurement information and a field that indicates availability of additional MDT measurement information left over with the UE to the base station;
• and
• repeating the receiving and the transmitting until all of the MDT measurement information is transferred to the base station.
