Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current layer 2 measurement technologies in heterogeneous networks, particularly in HetNet scenarios, are inadequate for accurately monitoring the system performance of Local eNBs, leading to incomplete or inaccurate data, which hinders timely and precise monitoring of system performance.
Innovation Solution
A method and device for performing layer 2 measurements in heterogeneous networks, where a UE aggregates resources from both Local and Macro eNBs, with the Local eNB performing measurements and reporting results to a processing entity, allowing for accurate data collection and processing of metrics like Scheduled IP throughput, Data Loss, Number of active UEs, and PRB usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing layer 2 measurement technology is used in heterogeneous networks, then measurement can be performed, but the measurement accuracy and completeness of Local eNB performance monitoring deteriorates
Solution Approach 1:
The patent segments the measurement and reporting functions by introducing separate measurement reporting mechanisms for Macro eNB and Local eNB. The Local eNB performs measurements and reports them directly to the OAM, while the Macro eNB reports its own measurements separately. This segmentation allows each eNB type to provide accurate measurements independently, resolving the contradiction between measurement accuracy and heterogeneous network adaptability.
2Device complexity
If measurement results are not accurately collected from Local eNB, then system performance monitoring can be simplified, but the completeness and timeliness of performance data deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the Local eNB directly reports measurement results to the OAM through a standardized interface. This feedback loop ensures that performance data from Local eNB is continuously collected and made available to the network management system, preventing information loss while maintaining manageable complexity through automated reporting.
3Ease of manufacture
If existing measurement protocols are applied to Local eNB, then implementation can be straightforward, but the resource utilization and system optimization deteriorates
Solution Approach 1:
The patent creates a universal measurement reporting framework that works for both Macro eNB and Local eNB through standardized interfaces and protocols. The OAM can receive and process measurement results from different eNB types uniformly, enabling easy implementation while improving resource utilization. The framework supports multiple functions including load balancing, resource allocation, and performance monitoring across the heterogeneous network.

AI summary
Embodiments of the present invention relate to the field of wireless communications, and disclosed are a layer 2 measurement and a result processing method and device under a heterogeneous network, used for solving the problem how to perform a layer 2 measurement under the heterogeneous network. In the present invention, a processing entity sends a measurement request for performing a layer 2 measurement to a local base station (local eNB); after receiving the measurement request, the local eNB performs the layer 2 measurement according to the measurement request and reports a measurement result of the layer 2 measurement to the processing entity sending the measurement request; and the processing entity receives the measurement result reported by the local eNB and obtained after the layer 2 measurement is performed according to the measurement request and processes the measurement result. As can be seen, the present invention solves the problem.
