Solution Overview

Problem

Existing techniques for maintaining neighborhood information in communication networks are inefficient, requiring manual provisioning and lacking dynamic updates, which hinders the provision of improved communication services to mobile nodes.

Innovation Solution

A system that dynamically obtains neighborhood information by establishing a communication session for a mobile node, using a neighborhood manager to record information about neighboring cells in a neighborhood information record, allowing for updated and detailed descriptions of neighbor cells.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual provisioning is used to maintain neighborhood information, then the cell site has basic neighborhood information, but the information is not updated dynamically and service efficiency is reduced

Engineering Contradiction:
Improveneighborhood information accuracyVSAvoidservice provisioning efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The cell site automatically obtains neighborhood information through communication sessions with mobile nodes without requiring manual provisioning. The system self-updates its neighborhood record by listening to communication sessions and extracting cell site information, eliminating the need for manual information entry and maintaining current data automatically.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors communication sessions between mobile nodes and cell sites, using the feedback from these sessions to dynamically update the neighborhood information record. This feedback mechanism ensures the neighborhood information remains current without manual intervention.

Inventive Principle:
Principle #23Feedback

2Loss of information

If dynamic obtaining of neighborhood information is implemented, then updated and detailed neighborhood information is achieved, but system complexity increases

Engineering Contradiction:
Improveneighborhood information freshnessVSAvoidinformation management complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The communication session infrastructure serves multiple functions: it enables mobile nodes to communicate with cell sites while simultaneously allowing cell sites to obtain neighborhood information. This multi-functionality avoids the need for separate dedicated information collection systems, reducing overall complexity.

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

Solution Approach 2:

The neighborhood information record acts as an intermediary structure that systematically organizes and stores cell site information obtained from communication sessions. This standardized record format simplifies the management and utilization of neighborhood information across the network.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Obtaining neighborhood information for a cell includes establishing the presence of a mobile node in a first cell having a first cell site. A communication session for the mobile node is facilitated. Neighborhood information is determined in response to facilitating the communication session. The neighborhood information describes a second cell having a second cell site. The neighborhood information is recorded in a neighborhood information record.
