Solution Overview

Problem

Wireless terminals connected to wireless communication networks often maintain multiple separate connections with servers, leading to excessive resource usage and energy consumption due to impromptu session setups and unsynchronized data traffic, which is inefficient for both the network and the terminal.

Innovation Solution

A communication synchronization device is implemented within the network to monitor and coordinate communication patterns between client applications and server devices, grouping sessions to reduce the number of channels used and synchronize data transmissions, thereby optimizing resource usage and energy efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate connections are maintained for each application, then application independence and functionality are preserved, but network resource usage and energy consumption increase excessively

Engineering Contradiction:

Improveapplication independenceVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent combines multiple separate application connections into a single unified connection between the wireless terminal and the network. The coordination entity manages multiple application data streams through this single connection, allowing applications to maintain independence while sharing common network resources, thereby reducing energy consumption associated with maintaining multiple separate connections.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a coordination entity as an intermediary that manages communication between applications and the network. This intermediary coordinates data transmissions, synchronizes traffic patterns, and manages the single connection, enabling multiple applications to function independently while reducing overall resource usage through centralized management.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If multiple separate connections are maintained for each application, then application-specific data transmission is enabled, but network resource occupation increases unnecessarily

Engineering Contradiction:

Improvedata transmission capabilityVSAvoidnetwork resources

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

Multiple application data streams are merged into a single network connection. The coordination entity multiplexes data from different applications over this shared connection, maintaining the ability to transmit application-specific data while reducing the total number of connections and associated network resource occupation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single connection established by the coordination entity serves multiple applications simultaneously. This universal connection handles data transmission for all applications, replacing the need for dedicated individual connections and thereby reducing network resource consumption while maintaining full data transmission capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If frequent session setups and shutdowns occur for each application, then application responsiveness is maintained, but network overhead and energy consumption increase

Engineering Contradiction:

Improveapplication responsivenessVSAvoidnetwork overhead

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The coordination entity establishes a single persistent connection in advance that serves multiple applications. This preliminary setup eliminates the need for repeated session establishment and teardown operations, reducing network overhead and time loss while maintaining application responsiveness through coordinated data management.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent maintains a continuous, persistent connection between the wireless terminal and the network through the coordination entity. This continuous connection remains active to serve multiple applications, eliminating the stop-start nature of frequent session setups and shutdowns, thereby reducing network overhead while preserving application responsiveness.

Inventive Principle:

Principle #20Continuity of useful action
