Problems solved by technology

Although there are different operators and different systems within the same target physical area and frequency band, how they deploy and use the same unlicensed spectrum resources cannot be predicted by operator A, that is, it is hidden, uncontrollable and However, through a large number of MDT measurement samples and reported statistical information, it is still possible for operator A to analyze certain rules, and then provide valuable reference for the subsequent better deployment and use of unlicensed spectrum resources
[0010] Since the respective service carriers / cells of the majority of operators are currently deployed on the licensed spectrum, the existing MDT technology cannot perform MDT measurements and collect statistics on the carrier / serving cells in the unlicensed spectrum, and there is no carrier RSSI or reception total Relevant measurement statistics of energy index quantities

Embodiment 1

[0138] S100: Operator A can configure and execute the Logged MDT operation for UE1 served by a certain eNB under its jurisdiction, and learn from the existing LTE wireless capability interaction process that the UE1 supports capabilities related to the content of the present invention. UE 1 in the RRC_IDLE state moves freely in the serving cell (configured on the authorized carrier of operator A) governed by the eNB, and the internal radio frequency module can support the measurement of wireless conditions in a specific unlicensed spectrum.

[0139] S101: OAM / TCE finds through the analysis of the internal specific unlicensed spectrum resource usage analysis module: in a certain period of time in the past, the UEs served by the eNB have unsatisfactory usage of unlicensed spectrum resources within a certain physical range: such as LAA The proportion of data offloading is small, and the probability of unlicensed resource competition and conflict is high, so it is decided to start ...

Embodiment 2

[0147] S200: Operator B can configure and execute an immediate MDT operation for a UE 2 served by a certain eNB under its jurisdiction, and learn from the existing LTE wireless capability interaction process that the UE2 supports capabilities related to the content of the present invention. UE 2 in the RRC_CONNECTED state moves freely in the serving cell (configured on the authorized carrier of operator B) governed by the eNB, and the internal radio frequency module can support the measurement of wireless conditions in a specific unlicensed spectrum.
