Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tunnel/bearer-based connection-oriented architectures are used in 3GPP mobile networks, then connection reliability is improved, but signaling overhead increases and mobility management efficiency deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmobility management efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent extracts the connection establishment and maintenance overhead from the routing protocol by implementing connectionless routing. Instead of using tunnel/bearer-based connection-oriented architectures that require complex setup and management signaling, the system uses IP-based connectionless routing where packets are routed independently without establishing dedicated connections, thereby eliminating the signaling overhead while maintaining reliability through intelligent routing decisions

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies universality by using a common IP-based routing protocol that works across multiple access technologies (wireless, wireline, satellite). This universal protocol replaces technology-specific connection-oriented mechanisms with a unified connectionless approach that can handle mobility management efficiently across different networks without requiring separate connection establishment procedures for each access type

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If siloed network architectures with different protocols are used for different access technologies, then network independence is maintained, but integration efficiency deteriorates

Engineering Contradiction:
Improvenetwork independenceVSAvoidintegration efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements universality by introducing a common IP-based routing protocol that serves multiple access technologies simultaneously. This universal protocol layer sits above the diverse access technologies (wireless, wireline, satellite) and provides unified connectionless routing functionality, enabling efficient integration while preserving the independence of underlying technologies through standardized interfaces

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses an intermediary approach by introducing a common routing protocol as a mediator between diverse access technologies and the core network. This intermediary layer translates and harmonizes the different protocols from various access technologies into a unified IP-based routing framework, enabling seamless integration without requiring direct compatibility between all access technologies

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If connection-oriented routing is used, then path reliability is improved, but latency increases due to connection setup and maintenance

Engineering Contradiction:
Improvepath reliabilityVSAvoidlatency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the connection setup and maintenance time from the routing process by implementing connectionless IP-based routing. Instead of establishing connections before data transmission and maintaining them throughout, the system routes packets directly using available routing information, eliminating the time delay associated with connection establishment while maintaining path reliability through intelligent routing decisions and fast failover

Inventive Principle:
Principle #2Taking out (Extraction)
