Solution Overview

Problem

In ProSe systems, there is a lack of methods for determining the timing to stop and start the use of Relay Service Codes, which are crucial for secure network connections, leading to inefficiencies in managing relay connections.

Innovation Solution

A terminal device includes a transmission/reception unit for requesting service authorization and a control unit to manage the timer for service authorization validity, enabling controlled start and stop times for relay connections based on received authorization messages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Relay Service Codes are regularly updated for security, then security is improved, but the complexity of managing start and stop timing increases

Engineering Contradiction:
ImprovesecurityVSAvoidmanagement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The network device pre-configures multiple Relay Service Codes and their corresponding validity periods before the terminal device needs to use them. The terminal device receives these pre-configured codes along with timing information (validity periods) from the network device, allowing it to automatically manage code transitions without complex real-time decision-making. This preliminary configuration approach simplifies the terminal device's management burden while maintaining security through regular code updates.

2Adaptability or versatility

If multiple Relay Service Codes are provided for the same service, then adaptability is improved, but the difficulty of determining usage timing increases

Engineering Contradiction:
Improveservice adaptabilityVSAvoidtiming determination difficulty
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The network device provides feedback to the terminal device in the form of validity period information for each Relay Service Code. When the terminal device receives multiple codes for the same service, each code is accompanied by timing information indicating when it becomes valid and when it expires. The terminal device uses this feedback information to automatically determine which code to use at any given time, eliminating the difficulty of manual timing determination while maintaining service adaptability.

Inventive Principle:
Principle #23Feedback

AI summary

A communication system implemented providing a service based on ProSe under the management of a network operator. Processing based on a discovery request procedure for discovering a proximity terminal is performed based on authentication of a server device operated by the network operator. In addition, the network operator updates the processing based on the discovery request procedure in accordance with a policy of the network operator.
