Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems lack the ability to manage adjacent cell relations automatically and in real time, leading to inaccurate configurations and increased communication load, which affects service quality and requires manual, time-consuming optimization.
Innovation Solution
A method and network architecture that utilize a hierarchical control strategy table to enable the Network Management System (NMS), Element Management System (EMS), and Network Element (NE) to analyze and adjust adjacent cell configurations in real time, automatically determining and updating adjacent cell lists based on preconfigured parameters or default strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration and analysis method is used to manage adjacent cell relations, then the system can maintain compatibility with existing network elements, but the processing time is long and the adjacent relation cannot be updated in time
Solution Approach 1:
The network element is empowered with self-service capability to automatically manage its own adjacent cell relations. The NE autonomously obtains adjacent cell configuration information, analyzes it according to hierarchical control strategies, and adjusts adjacent relation lists without requiring manual intervention from EMS or NMS, thereby dramatically reducing processing time while maintaining compatibility with existing network management structures
Solution Approach 2:
The hierarchical control strategy table is preconfigured with default strategies and parameters before network operation begins. This preliminary configuration enables the NE to immediately perform automatic adjacent relation management without requiring real-time negotiation or manual setup, thus reducing processing time while ensuring consistent and compatible operation across the network
2Productivity
If the NE is empowered with automatic adjacent relation management capability, then the processing efficiency is improved, but the device complexity increases
Solution Approach 1:
The NE's automatic adjacent relation management capability is controlled through parameter configuration rather than fundamental architectural changes. The hierarchical control strategy table contains configurable parameters that determine the degree of automation and the specific behaviors of the NE. By adjusting these parameters, the NE can operate in different modes (from fully manual to fully automatic), allowing processing efficiency to be improved while keeping device complexity manageable through parameter tuning rather than structural complexity
Solution Approach 2:
The adjacent relation management function is segmented into distinct modular components within the NE: an obtaining unit for acquiring configuration information, an analyzing unit for processing the information according to control strategies, and an adjusting unit for updating adjacent relation lists. This segmentation allows each component to be independently developed, tested, and optimized, improving overall processing efficiency while managing complexity through modular design
3Measurement precision
If real-time automatic management is implemented, then the adjacent cell list accuracy is improved, but the communication load increases
Solution Approach 1:
The hierarchical control strategy enables different levels of management (NMS, EMS, NE) to operate with different degrees of automation and different scopes of authority. The NE performs local automatic management for its own cells using preconfigured strategies, ensuring high accuracy for local adjacent relations. This local quality approach allows real-time automatic management to improve accuracy without requiring all network elements to engage in continuous communication, thus managing communication load effectively
