Solution Overview

Problem

In mobile communication systems, the inability to designate a specific base station to acquire operation information from another management device leads to excessive data transmission over inter-base station interfaces, causing bandwidth limitations and control delays.

Innovation Solution

A management device selects a designated network node to acquire operation information from a second network node, limiting the number of nodes acquiring information and optimizing data transmission through inter-network node interfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all first base stations acquire operation information from a second base station through inter-base station interfaces, then the management device can collect comprehensive operation information, but the bandwidth of inter-base station interfaces is excessively consumed and control delays occur

Engineering Contradiction:
Improveoperation information collection completenessVSAvoiddata transmission volume
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts and identifies a specific first base station from the plurality of first base stations to serve as the designated information acquisition node. This designated base station is responsible for acquiring operation information from the second base station, while other first base stations do not perform this function. This extraction of the acquisition function to a single designated node reduces redundant data transmission and resolves the bandwidth consumption problem while maintaining complete operation information collection at the management device.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a management device as an intermediary that receives operation information from a designated first base station and distributes it to other first base stations as needed. This intermediary approach allows comprehensive information availability without requiring all base stations to directly acquire information from the second base station, thereby reducing inter-base station interface bandwidth consumption while maintaining information completeness.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple first base stations are connected to a second base station with redundancy in mesh topology, then network reliability is improved, but the number of inter-base station interfaces increases causing excessive data transmission

Engineering Contradiction:
Improvenetwork connection reliabilityVSAvoidinterface management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by assigning different functional roles to different first base stations in the mesh topology. Specifically, one designated first base station is assigned the function of acquiring operation information from the second base station, while other first base stations maintain connectivity for redundancy purposes but do not perform information acquisition. This differentiated functional assignment maintains network reliability through redundant connections while avoiding excessive data transmission by limiting the information acquisition function to a single node.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If a designated first base station acquires operation information from a second base station, then data transmission volume is reduced and bandwidth efficiency is improved, but the system requires additional designation and selection mechanisms

Engineering Contradiction:
Improvedata transmission volumeVSAvoiddesignation mechanism complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling the management device to automatically select and designate a first base station for information acquisition based on operational criteria such as current load, connection status, and historical performance. The system autonomously makes this designation without requiring manual configuration, and can dynamically adjust the designated base station as network conditions change. This self-service approach reduces data transmission volume through targeted information acquisition while minimizing the complexity overhead by using automated, rule-based selection mechanisms.

Inventive Principle:
Principle #25Self-service
