Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communication systems face challenges in coexistence between different wireless services, particularly due to interference from adjacent channel frequencies, such as between LTE and MediaFLO systems in the 700 MHz band, which affects data transport and requires hardware modifications to preserve receive sensitivity and uplink data connections.

Innovation Solution

A method and apparatus that allow for the selection and redirection of data transport between wireless systems on a mobile terminal, suspending one service (like LTE) and redirecting it to another (like MediaFLO) using a Class Mark identifier, without requiring hardware filter modifications, thereby preserving receive sensitivity and maintaining uplink data connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If hardware filter modifications are made to preserve receive sensitivity, then receive sensitivity is preserved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:

Improvereceive sensitivityVSAvoidhardware modifications

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces hardware filter modifications with a software-based solution using Class Mark identifiers and service selection mechanisms. Instead of physically modifying the receiver hardware to filter adjacent channel interference, the system uses logical service selections and suspension mechanisms to manage coexistence between LTE and MediaFLO services, thereby preserving receive sensitivity without increasing device complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the operational parameters of the wireless system by introducing service selection states and suspension mechanisms. Rather than altering hardware characteristics, the system dynamically adjusts service operation parameters through Class Mark identifiers and network-controlled service selections to resolve interference issues while maintaining hardware simplicity

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If data transport is suspended on one wireless system to reduce interference, then interference is reduced, but productivity and service continuity deteriorate

Engineering Contradiction:

ImproveinterferenceVSAvoiddata transport continuity

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent implements dynamic service management where data transport can be suspended on one wireless system (e.g., LTE) when another system (e.g., MediaFLO) is selected, and automatically redirected or resumed when conditions change. This dynamic adjustment allows the system to minimize interference while maintaining service continuity through automatic redirection capabilities

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces service selection mechanisms and Class Mark identifiers as intermediaries between conflicting wireless services. These intermediaries enable the network to control which service is active at any given time, managing interference without permanently blocking data transport by allowing smooth transitions between services

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If hardware filter modifications are implemented to separate adjacent channel frequencies, then frequency separation is improved, but ease of manufacture and deployment worsen

Engineering Contradiction:

Improveadjacent channel interferenceVSAvoidhardware modifications

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent replaces physical filter modifications with software-based service selection and suspension mechanisms. Instead of manufacturing devices with specialized hardware filters for adjacent channel rejection, the system uses configurable service selections and Class Mark identifiers to manage frequency separation, greatly simplifying manufacturing and deployment

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a universal service selection mechanism that can handle multiple wireless services (LTE, MediaFLO, and potentially others) without requiring service-specific hardware modifications. This multi-functional approach allows a single device design to serve multiple purposes across different frequency bands and services, improving ease of manufacture

Inventive Principle:

Principle #6Universality (Multi-functionality)
