Solution Overview

Problem

Existing techniques for anchoring communication sessions in multiple networks are inefficient, often resulting in unnecessary long-distance charges and inefficient use of network resources, particularly when a mobile node moves between different wireless networks.

Innovation Solution

A system that gathers location information from a first wireless network to predict whether a mobile node will move into a second network, allowing for intelligent anchoring of communication sessions without manual configuration or access to proprietary databases, using prediction tables to determine the optimal anchor point based on usage patterns and location data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If communication session is anchored in the IP network, then the session can be maintained across different networks, but long distance charges apply to local communications

Engineering Contradiction:

Improvesession anchoring capabilityVSAvoidlong distance charges

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system performs preliminary actions by gathering location information and developing predictions about future node locations before the communication session actually needs to be anchored. This allows the system to pre-determine the optimal anchor point, avoiding the need to anchor in the IP network when local anchoring would suffice, thereby eliminating unnecessary long distance charges while maintaining session continuity capability

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If location information is manually configured or accessed from proprietary databases, then accurate anchoring decisions can be made, but system complexity and configuration effort increase

Engineering Contradiction:

Improveanchoring decision accuracyVSAvoidconfiguration complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The mobile node autonomously gathers its own location information from the wireless network it is already connected to, eliminating the need for manual configuration or access to proprietary databases. The node independently develops predictions based on this self-collected data, making accurate anchoring decisions without external assistance, thereby reducing system complexity while maintaining decision accuracy

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses the existing wireless network infrastructure for dual purposes: both for providing communication service and for gathering location information. This multi-functionality eliminates the need for separate location databases or configuration systems, reducing overall system complexity while maintaining accurate location-based anchoring decisions

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Gathering location information from a first wireless network to determine whether to anchor a communication session in a second wireless network, a mobile node capable of communicating with both the first wireless network and the second wireless network, includes receiving location information from the first wireless network as the mobile node moves through one or more service areas of the first wireless network. It is determined whether a triggering event occurs. If the triggering event occurs, the location information is stored to determine whether to anchor a session in the second wireless network.
