Solution Overview

Problem

Existing wireless network solutions fail to manage link cuts effectively when mobile terminals cross non-contiguous broadcasting zones, leading to interrupted information transmission.

Innovation Solution

A method where terminals send presence or absence signals to relay stations, which then communicate with a central site to ensure continuous information transfer by storing and retransmitting segments, even when terminals move between non-contiguous broadcast areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile terminals move between non-contiguous broadcast zones, then mobility and coverage area are improved, but link continuity and information transmission reliability deteriorate

Engineering Contradiction:
ImprovemobilityVSAvoidlink continuity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments information into multiple numbered segments and transmits them through different relay stations in non-contiguous broadcast zones. Each segment can be independently transmitted and reassembled at the destination, allowing continuous information transfer even when terminals move between zones with different relay station coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces relay stations as intermediaries between mobile terminals and the network. These relay stations receive, store, and retransmit information segments, acting as mediators that bridge the gap when terminals move between non-contiguous broadcast zones and maintain link continuity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If information is transmitted continuously across broadcast zone boundaries, then data transfer completeness is improved, but transmission complexity and management overhead increase

Engineering Contradiction:
Improvedata transfer completenessVSAvoidtransmission management
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by dividing information into numbered segments before transmission and establishing relay stations in advance at different broadcast zones. This preparation enables seamless continuation of transmission when terminals move between zones, reducing the complexity of managing cross-zone transmissions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where relay stations send presence signals to indicate terminal locations and receive transmission requests from the central site. This feedback system automates the management of segmented information transmission across multiple broadcast zones, reducing manual intervention complexity.

Inventive Principle:
Principle #23Feedback

3Reliability

If relay stations store and retransmit segments across zones, then information transmission reliability is improved, but network resource consumption and latency increase

Engineering Contradiction:
Improveinformation transmissionVSAvoidtransmission latency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs dynamic relay station selection based on terminal presence and broadcast zone coverage. Relay stations actively monitor terminal locations through presence signals and dynamically route information segments through optimal paths, reducing unnecessary storage and retransmission delays while maintaining reliability.

Inventive Principle:
Principle #15Dynamics

AI summary

The method involves dividing information to be transmitted into a series of consecutive segments. Entry of a terminal in a coverage area is signaled by a presence signal, and exit of the terminal from the coverage area is signaled by an absence signal, where the area is covered by a relay station. Transmission of a segment of the information between the terminal and the station is conditioned by a prior reception of the presence signal and by the reception of an acknowledgement relative to the transmission of the segment. Independent claims are also included for the following: (1) a network infrastructure comprising a relay station connected to a central site (2) a relay station of a communication network constituted by coverage areas.
