Solution Overview

Problem

In in-building communication systems, managing multiple repeaters and a repeater management device separately requires a method for 1:1 communication without adding complexity or changing hardware, as existing solutions lack efficient communication pathways between different manufacturers' equipment.

Innovation Solution

A data transmission/reception method using port numbers to enable 1:1 communication between multiple repeaters and a repeater management device, employing a mapping table between IP addresses and port numbers to specify communication paths, allowing the repeater management server to transfer packets to intended repeaters without additional processing or hardware changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate management servers are implemented for DU and repeaters, then management functionality is provided, but device complexity increases and 1:1 communication between repeaters and management server cannot be achieved

Engineering Contradiction:
Improvemanagement functionalityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The DU acts as an intermediary between the repeater management server and multiple repeaters. The DU receives management packets from the server, extracts destination address information, and forwards packets to the corresponding repeaters. This intermediary approach enables 1:1 communication without requiring separate management servers for each repeater, thus reducing system complexity while maintaining management functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If multiple repeaters are managed by a single management server, then device complexity is reduced, but communication pathways between server and individual repeaters become indistinct

Engineering Contradiction:
Improvesystem complexityVSAvoidcommunication path identification
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent applies local quality by assigning unique destination address information to each repeater. When the management server sends packets, it includes specific destination address information that identifies the target repeater. The DU uses this destination address information to determine the correct forwarding path for each packet, ensuring that communication pathways remain distinct and identifiable even though multiple repeaters are managed by a single server.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If DU acts as simple communication path, then ease of operation is improved, but ability to enable 1:1 communication between management server and repeaters is insufficient

Engineering Contradiction:
ImproveDU operation simplicityVSAvoidcommunication capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The DU performs multiple functions: it acts as a communication path between the management server and repeaters, extracts destination address information from packets, determines forwarding paths based on this information, and forwards packets to the appropriate repeaters. This multi-functionality allows the DU to maintain operational simplicity while enabling 1:1 communication between the management server and individual repeaters, thus achieving both ease of operation and communication versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)
