Solution Overview

Problem

In wireless communication systems, the efficient discovery and communication between User Equipments (UEs) in proximity are hindered by the need for secure transmission of user information, which is often compromised by direct transmission of account details, leading to privacy issues and inefficient data exchange.

Innovation Solution

A method and apparatus where a UE generates a discovery code from user account information, which is then transmitted through a middle layer, ensuring privacy by converting the information into a coded format that can only be decoded by intended recipients, using a ProSe manager and radio interface within the 3GPP layer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user account information is transmitted directly between UEs, then discovery and communication can be established, but user privacy is compromised and security is weakened

Engineering Contradiction:
ImprovesecurityVSAvoidprivacy protection
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces a middle layer (ProSe manager) that acts as an intermediary between the application layer and radio interface layer. This middle layer generates discovery codes from user account information and manages the encoding/decoding process, preventing direct exposure of sensitive user data while enabling discovery functionality. The intermediary layer ensures that raw user information never traverses the wireless interface, thus maintaining both security and privacy.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a coded representation (discovery code) of the user account information instead of transmitting the actual user data. This copy contains sufficient information for discovery purposes while being meaningless without the corresponding decoding key, thus protecting user privacy while enabling the discovery function.

Inventive Principle:
Principle #26Copying

2Reliability

If discovery codes are generated and transmitted through middle layer, then user privacy is protected, but system complexity increases

Engineering Contradiction:
Improveprivacy protectionVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the communication system into distinct layers: application layer, middle layer (ProSe manager), and radio interface layer. Each layer has a specific function - the application layer handles user information, the middle layer generates and manages discovery codes, and the radio interface layer transmits the coded data. This segmentation isolates complexity to specific layers while maintaining simplicity in others, making the overall system manageable despite the added privacy protection mechanisms.

Inventive Principle:
Principle #1Segmentation
