eNB Congestion Detection for Trunking Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trunking communication systems face inefficiencies in detecting and managing congestion or overload in MBMS networks, leading to unnecessary resource wastage and reduced work efficiency as all eNBs in an MBSFN area report the same information, affecting the trunking service.
Innovation Solution
A method and system where selected eNBs detect congestion or overload and send specific indication information to a GCS AS, allowing the system to determine the start or end of congestion in an MBMS area and adjust the manner of trunking service data transmission, thereby reducing network load and improving service efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all eNBs in an MBSFN area detect and report congestion or overload status, then the detection coverage is complete, but the network resource consumption increases and work efficiency decreases due to redundant reporting
Solution Approach 1:
The patent divides the MBSFN area into multiple congestion detection areas, each managed by a specific eNB. Instead of all eNBs reporting to the same GCS AS, each segmentation unit (eNB) independently manages its own detection area, reducing redundant cross-reporting and improving overall system efficiency while maintaining complete coverage.
Solution Approach 2:
The patent creates a multi-functional GCS AS architecture where the server can handle multiple types of requests (congestion detection, service establishment, service interruption) and serve multiple eNBs simultaneously. This universal design allows the system to maintain comprehensive detection capabilities while optimizing resource allocation across different functional domains.
2Measurement precision
If all eNBs send congestion indication information to GCS AS, then the congestion detection is thorough, but the M2 interface resource consumption increases due to redundant information transmission
Solution Approach 1:
The patent extracts and removes the redundant reporting function from the traditional architecture. By assigning each eNB to manage its own congestion detection area and report only when necessary (when congestion status changes), the system eliminates duplicate information transmission while maintaining accurate congestion detection through selective reporting.
Solution Approach 2:
The patent implements a feedback mechanism where eNBs continuously monitor congestion status in their respective areas and provide feedback to the GCS AS only when the status changes. This feedback-based approach ensures accurate congestion detection while minimizing interface resource consumption by avoiding continuous redundant reporting.
3Productivity
If selected eNBs detect congestion and report to GCS AS, then the network resource utilization improves, but the system complexity increases due to area management and selection mechanisms
Solution Approach 1:
The patent applies preliminary action by pre-assigning congestion detection areas to specific eNBs before congestion events occur. This pre-configuration simplifies the system operation during congestion events, as eNBs already know their designated areas and reporting responsibilities, reducing the need for complex real-time decision-making while improving resource utilization.
