Solution Overview

Problem

Existing communication line sharing systems fail to provide sufficient privacy measures for both the owner and borrower, as communications and information are often accessible to both parties, leading to privacy concerns and unauthorized access.

Innovation Solution

A network-based system that utilizes user-specific IDs to securely route communications and information, ensuring that only intended recipients, whether the owner or borrower, can access specific communication lines, while preventing unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If communication line sharing is implemented without user-specific routing, then borrowers can utilize the network and communication features without roaming issues, but both owner and borrowers can access all communications transmitted via the communication line leading to privacy concerns

Engineering Contradiction:
Improvecommunication line sharing capabilityVSAvoidcommunication privacy
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments communication routing by creating user-specific routing paths for each borrower. The system divides the shared communication line into multiple isolated communication channels, where each channel is associated with a specific borrower's user ID. This segmentation ensures that while the communication line is shared, the information flow is divided into separate, private channels that prevent unauthorized access between users.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a network entity (such as a serving gateway or access network entity) as an intermediary that mediates communication routing. This intermediary receives communications on the shared line, determines the intended recipient based on user IDs, and forwards communications only to the appropriate borrower device. The intermediary prevents direct access between owner and borrowers, ensuring privacy while enabling shared line functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If all communications are routed to all users on a shared line, then users can access communications freely, but transmission loads increase and confidentiality is compromised

Engineering Contradiction:
Improvecommunication accessibilityVSAvoidtransmission load
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent extracts the routing determination function from the general communication flow and implements it at the network level. Instead of allowing all communications to reach all users, the system extracts and applies user ID-based routing rules early in the communication path, filtering out communications that are not intended for specific borrowers. This extraction prevents unnecessary transmission loads and energy consumption while maintaining ease of access for authorized users.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Techniques for sharing or borrowing communication lines are discussed herein. For example, a system can distinguish between a communication line borrower and a communication line owner based on unique user identifiers. The system can identify the communication line borrower as an intended recipient of communication information and user information based on a unique identifier of the communication line borrower that is associated with the communication information and user information by one or more network nodes. The system can secure the shared communication line against activation by the communication line owner and additional communication line borrowers while the shared communication line is assigned to the communication line borrower.
