Solution Overview

Problem

Conventional mobile network systems fail to optimize network usage by not considering the type of content being delivered, leading to network congestion during peak hours, especially for non-time sensitive content like software updates and content synchronization, which can be alleviated by selectively deferring delivery based on network load.

Innovation Solution

Implementing network devices and methods that include a communication interface and processing unit to determine whether to defer the delivery of non-time sensitive content based on current network load, using historic or near real-time data to decide when to send the content, thereby reducing congestion and improving user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If content delivery is performed promptly without considering network load, then user satisfaction and service quality are improved, but network congestion occurs during peak hours

Engineering Contradiction:
Improveservice qualityVSAvoidnetwork congestion
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system performs preliminary assessment of network load conditions before initiating content delivery. The network device determines whether to defer delivery based on current network state, preventing congestion before it occurs by avoiding simultaneous deliveries during peak load periods

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts content delivery timing based on real-time network load conditions. Delivery decisions are flexible and adaptive, switching between immediate delivery and deferred delivery modes according to network state, rather than following a fixed delivery schedule

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If non-time sensitive content is delivered during peak hours, then content availability is improved, but network efficiency deteriorates

Engineering Contradiction:
Improvecontent availabilityVSAvoidnetwork efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system implements periodic delivery of non-time sensitive content by deferring delivery until off-peak hours when network load is lower. Content is delivered in periodic intervals rather than immediately, matching network capacity cycles and improving overall network efficiency

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system changes the timing parameter of content delivery based on network load conditions. By adjusting the delivery time parameter from immediate to deferred, the system maintains content availability while improving network efficiency during peak periods

Inventive Principle:
Principle #35Parameter changes

3Object-generated harmful factors

If content delivery is deferred based on network load, then network congestion is reduced, but delivery time increases

Engineering Contradiction:
Improvenetwork congestionVSAvoiddelivery time
Core Design Contradiction:
Object-generated harmful factorsVSLoss of time

Solution Approach 1:

The system applies different delivery strategies to different types of content based on their time sensitivity characteristics. Time-sensitive content receives immediate delivery while non-time sensitive content is deferred, creating localized quality differences in delivery timing that reduce overall congestion without unnecessarily delaying critical content

Inventive Principle:
Principle #3Local quality
