Mobile Terminal Idle Mode Measurement Logging for Connection Failure Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face inefficiencies in radio network optimization due to the time-consuming and labor-intensive nature of drive tests, particularly in reporting measurement information associated with network connection failures, which hinders effective radio environment analysis and optimization.
Innovation Solution
A method where user equipment transmits a connection request message, determines if the Registered Public Land Mobile Network (RPLMN) matches a Selected PLMN, and reports measurement information associated with connection failures logged during the RRC connection establishment process, enabling the network to utilize this information for optimization even in cases of connection failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal performs measurements only in connected mode, then the measurement process is simple, but measurement information associated with connection failures cannot be obtained
Solution Approach 1:
The terminal performs measurements and logs measurement information in idle mode before connection establishment, so that when connection failure occurs, the measurement data is already available for reporting. This preliminary action ensures measurement information completeness without complicating the connected-mode measurement process.
2Productivity
If the terminal reports measurement information immediately upon connection, then the network optimization can proceed quickly, but additional signaling overhead is incurred
Solution Approach 1:
The patent extracts the measurement information reporting from the normal connection procedure by introducing a separate indication mechanism. The terminal includes a specific indicator in the connection setup complete message to signal the presence of logged measurement information, allowing the network to selectively request and process only when needed, thus reducing unnecessary signaling overhead while maintaining optimization efficiency.
3Measurement precision
If traditional drive tests are used for radio network optimization, then comprehensive measurement data can be collected, but the process is time-consuming and labor-intensive
Solution Approach 1:
The terminal automatically performs measurements in idle mode and logs measurement information without requiring operator intervention. The terminal also autonomously determines when to report the logged information based on connection establishment events. This self-service approach eliminates the need for manual drive tests while maintaining measurement accuracy, significantly reducing both time consumption and labor requirements.

AI summary
Disclosed are a method and an apparatus for transmitting and receiving measurement information in a mobile communication system. A terminal transmits a connection request message to a network and reports to the network, connection failure-related measurement information when a registered public land mobile network (RPLMN) included in a connection setup message received from the network corresponds to a pre-stored and selected public land mobile network (PLMN) and the connection failure-related measurement information stored with the selected PLMN is available.
