D2D Network Credential Sharing for Seamless Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network server registration credentials exchange methods in device-to-device (D2D) networks are limited in enabling seamless access to network services across devices without requiring individual registration and credential management, especially in scenarios involving access points (APs) and multiple user equipment (UEs).
Innovation Solution
The solution involves sharing and redistributing network registration credentials within D2D networks, allowing external devices to access network services using shared credentials, either directly or through APs, thereby facilitating access without the need for individual registration with each network server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each D2D client device registers individually with the network server, then each device can access network services independently, but the complexity of credential management increases and battery life is consumed due to multiple registration operations
Solution Approach 1:
The patent implements credential sharing by creating copies of network registration credentials from one device and distributing them to other D2D client devices. Instead of each device obtaining credentials independently through separate registration procedures, the system copies credentials from a source device to target devices, significantly reducing the complexity of credential management while maintaining independent access capability.
2Productivity
If multiple devices register with the network server, then each device can access network services, but the energy consumption increases due to repeated registration and communication operations
Solution Approach 1:
The patent performs credential copying and distribution in advance before the actual network service access is needed. By preliminarily distributing credentials to multiple D2D client devices through direct device-to-device communication, the system eliminates the need for repeated registration operations when services are accessed, thereby conserving battery life while maintaining high service accessibility.
3Use of energy by moving object
If D2D client devices communicate directly without AP involvement, then battery life is conserved by avoiding AP communication, but the capability to access certain network services is limited
Solution Approach 1:
The patent implements a universal credential sharing mechanism that works across multiple communication scenarios. The copied credentials enable D2D client devices to access network services whether communicating directly with each other or through access points. This multi-functional approach maintains energy efficiency by enabling direct D2D communication while simultaneously providing the versatility to access various network services that may require AP involvement.

AI summary
In an embodiment, a client device receives a set of network registration credentials configured to authorize access to one or more network services provided by a network server. The client device shares the set of network registration credentials with an external device (e.g., a peer client device or an access point) via D2D. In another embodiment, a device (e.g., the external device or a different device) receives the set of network registration credentials via D2D and interacts with the network server to access a network service using the set of network registration credentials. In another embodiment, the device shares the set of network registration credentials with another client device via D2D.
