Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently establishing alternate access paths between user equipment (UE) and network nodes, particularly in environments with interference or limited connectivity, which can impact the reliability and efficiency of communication.

Innovation Solution

The implementation of a repeater that transmits an alternate access path indication to UE via a side channel, allowing for the establishment of a connection to a network node through an access link connection path, enhancing communication reliability and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a repeater is used to establish alternate access paths in wireless networks, then communication reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a repeater as an intermediary device that establishes alternate access paths between user equipment and network nodes. The repeater receives signals from one path and transmits them through an alternate path, thereby improving communication reliability when primary paths are blocked or interfered with. This mediator approach resolves the contradiction by adding a specialized component that handles path switching without requiring complex modifications to existing UE or network node devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If alternate access paths are established through repeater communication, then connectivity is improved, but communication overhead increases

Engineering Contradiction:
ImproveconnectivityVSAvoidcommunication overhead
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements preliminary action by having the repeater pre-establish and monitor alternate access paths before they are needed. The repeater maintains readiness to switch to alternate paths by pre-configuring multiple communication routes and pre-establishing connections with network nodes. This approach improves connectivity adaptability while minimizing communication overhead during actual path switching, as the alternate paths are already prepared and require minimal signaling when activated.

Inventive Principle:
Principle #10Preliminary action
