Method and system of providing MDT measurement information to a base station in a wireless network environment
First Claim
1. A method of providing minimization of drive test (MDT) measurement information to a base station by a user equipment (UE), the method comprising:
- receiving a UE information request message to transfer logged MDT measurement information;
determining 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);
transmitting 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.

Abstract
The present invention provides a method and system of providing minimization drive test (MDT) measurement information to a base station in a wireless communication network. In one embodiment, a method includes indicating availability of MDT measurement information logged by user equipment to a base station in a wireless network environment. The method further includes receiving an information request message to transfer the MDT measurement information in response to the indication. The method includes transmitting an information response message including at least a portion of the MDT measurement information to the base station, where the information response message indicates whether any portion of MDT measurement information is leftover with the user equipment. The method then includes repeating the above steps of receiving and transmitting till the entire MDT measurement information is transferred to the base station.

6. 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. - View Dependent Claims (7, 8, 17, 20)

9. 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. - View Dependent Claims (10, 15, 16, 19)
