Embodiment 1

[0130] This embodiment is a processing manner for the eNB on the network side of the eDDA service.

[0131] According to the PPI information reported by the UE, the eNB on the network side can clearly know the start and end time of the UE's only small data service transmission.

[0132] When the UE only transmits small data services, there are two ways to solve the inaccuracy caused by small data services to the network side:

[0133] Alt1: According to the PPI report, the eNB ignores the statistics of the small data volume service during the period when the PPI is reported as low power, does not enable the measurement cycle, and does not report the throughput or data volume to the TCE.

[0134] Alt2: According to the PPI report, the eNB stamps the eDDA mark on the statistics of the small traffic data and sends it to the TCE.

[0135]If operators want to separately count the transmission characteristics of eDDA small service data, they can collect the MDT statistical results ...

Embodiment 2

[0138] This embodiment is the processing manner of the eNB on the network side for the IDC service.

[0139] For a UE with IDC capability, if the network sends the denial parameter, before the UE’s IDC problem ends, that is, before the UE reports an empty IDC indication that does not contain interference information, there are two ways to ensure the accuracy of the MDT measurement results :

[0140] Alt1: eNB does not perform statistics on MDT measurement results for UEs configured with denial parameters, does not enable any measurement cycle, and does not report throughput or data volume results to TCE;

[0141] Alt2: The eNB performs MDT measurement statistics on the UE configured with the denial parameter, and marks the statistics result of the UE with an IDC mark, and then sends it to the TCE.

[0142] Further, the identifier may include the configuration content of the denial parameter issued by the network to the UE.

Embodiment 3

[0144] This embodiment is a processing manner for the eNB on the network side of the autonomous gap.

[0145] The UE may have the ability to use the autonomous gap to read the system information of inter-frequency / different-technology neighboring cells without the need for the network side to deliver and display the measurement gap.

[0146]

[0147] When the network learns that the UE has the ability to read inter-frequency / inter-technology system information using autonomous gap, if the network configures system information-related measurements such as report CGI for the UE, it means sending a message to the UE instructing the UE to read the information. During the period of receiving the system information reported by the UE, the eNB on the network side stops the throughput or data volume measurement and statistics by itself; or marks the statistical results related to this period of time with an autonomous gap mark, and then sends it to the TCE.

Abstract

The present invention provides a method and device for minimizing drive test MDT measurement. The method includes: according to the service transmission characteristics of the UE or the optimized processing of the service transmission of the UE, determine that the UE enters a special communication state that affects the accuracy of the MDT measurement result; Before the UE ends the special communication state, perform MDT measurement on the UE, and identify or adjust the obtained MDT measurement result, or suspend the MDT measurement on the UE. The present invention applies an appropriate processing method to optimize the processing of data service transmission or the influence of the service characteristics itself on the statistics of MDT measurement results, and minimize the statistics of drive test results as accurately as possible, which is beneficial to better realize network automation. optimization.

Description
