Solution Overview

Problem

Wireless relays in communication networks are not optimized to efficiently and intelligently support mobile data services like media streaming and software downloading, despite providing connectivity between user devices and communication networks.

Innovation Solution

The implementation of a wireless communication network architecture where wireless relays use Time-To-Live (TTL) for content requests, with access relays transferring requests to serving relays that store the data, and terminating relays stopping request propagation when TTL expires, optimizing data delivery between user devices and communication networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If wireless relays are deployed to extend network range, then connectivity coverage is improved, but network efficiency for data services deteriorates

Engineering Contradiction:

Improvenetwork coverage areaVSAvoiddata service efficiency

Core Design Contradiction:

Area of stationary objectVSProductivity

Solution Approach 1:

The patent segments the relay network into three functional types (access relays, serving relays, and terminating relays) based on their role in handling content requests. This segmentation allows each relay to specialize in specific tasks, improving overall network efficiency while maintaining extended coverage through the distributed relay architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces Time-To-Live (TTL) as a parameter to control content request propagation. By changing the state of request forwarding based on TTL expiration, the system optimizes data delivery efficiency without sacrificing coverage, as relays can intelligently forward or terminate requests based on this parameter.

Inventive Principle:

Principle #35Parameter changes

2Length of stationary object

If wireless relays forward all content requests, then data delivery reach is improved, but network resource consumption deteriorates

Engineering Contradiction:

Improvedata delivery reachVSAvoidnetwork resource consumption

Core Design Contradiction:

Length of stationary objectVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by having serving relays check their local content stores before forwarding requests. This preliminary check prevents unnecessary request propagation and data transmission, reducing network resource consumption while maintaining delivery reach through intelligent request routing.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where relays respond to content requests based on their stored content status. Serving relays provide feedback by either fulfilling requests from their stores or terminating forwarded requests, creating a feedback loop that optimizes resource usage while maintaining delivery capability.

Inventive Principle:

Principle #23Feedback

3Speed

If wireless relays store data content locally, then data access speed is improved, but device complexity deteriorates

Engineering Contradiction:

Improvedata access speedVSAvoidrelay device complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent segments the relay functionality into distinct roles: access relays handle user connectivity, serving relays handle content storage and request fulfillment, and terminating relays handle request termination. This segmentation allows relays to specialize in specific functions, improving data access speed through local content storage while managing device complexity through functional specialization.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If wireless relays propagate content requests throughout the network, then content discovery capability is improved, but network traffic overhead deteriorates

Engineering Contradiction:

Improvecontent discovery capabilityVSAvoidnetwork traffic overhead

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent applies partial action by having relays propagate content requests only partially through the network based on TTL expiration and serving relay identification. This partial propagation maintains content discovery capability by allowing requests to reach relevant relays while avoiding excessive traffic overhead through controlled request termination.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A wireless communication network serves data content to a wireless user device. An access wireless relay wirelessly receives a user request for the data content from the wireless user device. The access wireless relay wirelessly transfers the data content to the wireless user device when it stores the data content. When the access wireless relay does not store the data content, it transfers content requests having a Time-To-Live (TTL). Serving wireless relays receive the content requests during the TTL. The serving wireless relays transfer the data content to the access wireless relay if they store the data content. The serving wireless relays forward the content requests with the TTL when they do not store the data content. Terminating wireless relays receive the content requests after the TTL. The terminating wireless relays stop forwarding the content requests.
