Solution Overview

Problem

In mobile communication systems, existing technologies face challenges in efficiently routing data packets between mobile nodes due to default routing paths that can lead to network resource wastage and overloading, especially when multiple mobility entities are involved.

Innovation Solution

The configuration component stores information about the delegating mobility entity when assigning addresses or address prefixes, allowing source mobility entities to directly contact destination mobility entities for route optimization, thereby enabling full control over the routing process without involving configuration components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If default routing paths are used through mobility entities, then mobile nodes can be reached reliably, but network resources are wasted and paths become overloaded

Engineering Contradiction:
Improvereachability of mobile nodesVSAvoidnetwork resource utilization
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent segments the routing function by separating the mobility management function (handled by mobility entities) from the routing path determination (optimized through configuration components). This allows reachability to be maintained through mobility entity association while enabling optimized routing paths that bypass unnecessary mobility entities, thus reducing network resource waste while preserving reliability.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If address assignment is centralized in mobility entities, then mobility management is simplified, but routing optimization between mobile nodes is limited

Engineering Contradiction:
Improvemobility management complexityVSAvoidrouting efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent introduces configuration components as intermediary entities between mobility entities and mobile nodes. These intermediaries handle address assignment and store associations between mobile node identifiers and addresses, enabling routing optimization without complicating the core mobility management function. The intermediary facilitates direct routing paths while mobility entities maintain their simplified role.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If configuration components delegate address assignment, then address management becomes flexible, but information about delegating mobility entities is lost

Engineering Contradiction:
Improveaddress assignment flexibilityVSAvoiddelegating entity information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent applies preliminary action by having configuration components store information about the delegating mobility entity at the time of address assignment. This pre-stored information enables later routing optimizations by allowing source mobility entities to identify and contact the appropriate destination mobility entities directly, without needing to re-query or lose track of the delegation relationships.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method for facilitating communication in a mobile communication system in which address-delegating entities are involved, wherein mobile nodes attaching to said communication system get assigned an address or address prefix, wherein said address or address prefix assignment is delegated from an entity being associated with mobility management - mobility entity - to some other configuration component (2), is characterized in that said configuration component (2), upon being delegated by a mobility entity to assign a mobile node an address or address prefix, stores information about said delegating mobility entity. Furthermore, a corresponding mobile communication system with address delegation support is disclosed.
