MDT Data Reporting With Terminal Identity Attribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network monitoring methods, such as MDT, cannot accurately determine whether network abnormalities are caused by terminals or the network itself due to the lack of terminal identity information in reported data.
Innovation Solution
Incorporating an uplink information exchange request message with an international mobile subscriber identity (IMSI) and trace references to obtain terminal identities, allowing accurate attribution of network abnormalities between terminals and the network by reporting MDT data with corresponding identities to the OAM.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If MDT data is reported without terminal identity information, then the reporting process is simple and fast, but the ability to determine whether network abnormalities are caused by terminals or the network itself deteriorates
Solution Approach 1:
The patent combines terminal identity information (IMSI) with MDT measurement data by reporting both through the same signaling path (RRC connection). The RNC reports both the MDT data and the terminal identity to the OAM system, merging what were previously separate information streams into a unified reporting mechanism that maintains efficiency while enabling accurate attribution.
Solution Approach 2:
The RNC acts as an intermediary that collects both the terminal identity and MDT data, then forwards both to the OAM system. This intermediary role allows the system to maintain the simple reporting path while ensuring that identity information is properly associated with measurement data at the network side.
2Measurement precision
If terminal identity information is included in MDT data reporting, then the ability to determine abnormality sources is improved, but the complexity of the reporting mechanism increases
Solution Approach 1:
The existing RRC signaling mechanism is made multi-functional by using it for both traditional MDT data reporting and terminal identity reporting. Instead of creating a separate dedicated reporting path, the patent leverages the existing universal RRC interface to carry both types of information, avoiding additional complexity while achieving the desired functionality.
Solution Approach 2:
The terminal identity information is obtained and prepared in advance by the RNC before the actual MDT data reporting occurs. The RNC maintains an association between terminal identities and their measurement data, so when reporting is needed, both pieces of information are already ready to be transmitted together, streamlining the process.
3Stability of the object's composition
If separate reporting paths are used for MDT data and terminal identity, then information organization is clear, but the reporting process becomes more complex and time-consuming
Solution Approach 1:
The patent merges the reporting of terminal identity and MDT data into a single unified reporting process through the RRC interface. Both information types are transmitted together in the same signaling flow to the OAM, maintaining clear information organization while eliminating the need for separate reporting paths and reducing overall process complexity.

AI summary
The present invention discloses a method and an apparatus for obtaining terminal minimization of drive-tests data, relates to the field of communication technologies, and solves a problem that when determining, according to minimization of drive-tests (MDT) data, that a current operating status of a network is abnormal, an operation, maintenance and administration (OAM) cannot accurately determine whether the abnormality of the network is caused by a terminal or the network itself since the MDT data received by the OAM does not include an identity of the terminal. The method includes: obtaining MDT data measured by a terminal and an identity of the terminal; and reporting the MDT data measured by the terminal and the identity of the terminal to an OAM. Embodiments of the present invention are mainly applied to a process of obtaining terminal minimization of drive-tests data.
