UE Success Reporting for IoT Coverage Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Minimization of Drive Tests (MDT) technologies for user equipment with coverage enhancement functions, such as Machine Type Communication (MTC) and Internet of Things (IoT) devices, lack a mechanism to effectively report successful service reception and associated parameters, which is crucial for network optimization.
Innovation Solution
A communication control method where user equipment determines successful service reception, stores success information including cell identifiers and attempt counts, and transmits this data to the network, enabling improved network optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment with coverage enhancement functions (MTC/IoT devices) is used to reduce cost and power consumption, then device cost and power consumption are reduced, but the ability to report successful service reception and network optimization data is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where user equipment reports successful service reception information to the network. The UE stores success information including cell identifiers and attempt counts in a buffer, then transmits this data to the network node when connected, enabling the network to optimize coverage and service delivery based on actual UE reception experiences.
2Measurement precision
If traditional MDT function is applied to user equipment with coverage enhancement, then network measurement capability is maintained, but the mechanism lacks the ability to report successful service reception details
Solution Approach 1:
The patent introduces dynamic reporting capabilities where the UE adapts its reporting behavior based on service reception outcomes. The system dynamically stores success information when services are successfully received and transmits this information to the network, creating a flexible reporting mechanism that complements traditional MDT measurements with actual service delivery data.
3Loss of information
If user equipment stores and transmits detailed success information including attempt counts, then network optimization quality is improved, but device memory and processing requirements increase
Solution Approach 1:
The patent extracts only the essential information needed for network optimization from the complex service reception process. Specifically, it stores success information containing cell identifiers and attempt counts - the minimum necessary data to enable network optimization without requiring the UE to store or process extensive service details, maintaining a balance between information quality and device complexity.

AI summary
A communication control method according to an aspect is a communication control method executed by a user equipment. The communication control method comprises determining that the user equipment successfully receives a predetermined service from a predetermined cell; in response to determining that the user equipment successfully receives the predetermined service, storing success information in a memory of the user equipment; and transmitting to a network, the stored success information. The success information includes: an identifier of the predetermined cell, an identifier of the user equipment allocated by the predetermined cell, and information indicating a number of attempts before successfully receiving the predetermined service.
