Access Point Bridging PAN and LAN for Device Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in maintaining device collaboration when they leave one device behind and move out of its Personal Area Network (PAN) range, preventing access to collaborative features.
Innovation Solution
A communication system that bridges a Personal Area Network (PAN) with a Local Area Network (LAN) using an access point, allowing devices to authenticate and establish a second network service, enabling continued access to collaborative features even when a device is out of range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices communicate via PAN (Personal Area Network), then security and direct device collaboration are improved, but device collaboration is lost when devices move out of PAN range
Solution Approach 1:
The patent introduces an access point as an intermediary between mobile devices. When devices are within PAN range, they communicate directly. When out of range, the access point mediates communication by receiving data from one device and forwarding it to the other device, maintaining collaboration continuity while allowing physical separation.
Solution Approach 2:
The patent extends the collaboration network from a single PAN dimension to multiple dimensions by incorporating LAN (Local Area Network) infrastructure. This creates a hybrid network architecture where devices can switch between direct PAN communication and indirect LAN-mediated communication, adding spatial flexibility while maintaining collaboration.
2Ease of operation
If devices are kept within PAN range for collaboration, then direct communication is maintained, but user mobility and device separation are restricted
Solution Approach 1:
The access point serves as a mediator that enables user mobility while maintaining collaborative interface connectivity. It receives authentication credentials from devices and manages the hybrid PAN-LAN connection, allowing users to move freely while their devices remain connected through the access point infrastructure.
Solution Approach 2:
The access point provides multi-functional support by handling both PAN authentication and LAN communication management. It authenticates devices using PAN credentials and simultaneously manages their connection to the broader LAN, enabling a single infrastructure to support multiple communication modes and use cases.
3Reliability
If PAN authentication is required for device collaboration, then security is improved, but complex authentication procedures prevent seamless collaboration when devices separate
Solution Approach 1:
The system performs preliminary PAN authentication when devices are initially paired or connected. The access point stores the authenticated credentials and uses them to maintain continuous collaboration without requiring repeated authentication procedures, thereby preserving security while simplifying ongoing operations.
Solution Approach 2:
The access point automatically manages authentication using pre-stored PAN credentials. Once initial authentication is complete, the system handles subsequent connection management autonomously without requiring user intervention or complex authentication procedures, maintaining security while enabling seamless collaboration.

AI summary
An access point is provided that bridges a PAN with a LAN. When the access point receives, from a first mobile device, a request to authenticate with the access point for a first network service and a request to establish a second network service, wherein the second network service provides for bridging a PAN with a LAN, the access point determines a credential to be used by mobile devices who wish to join the second network service and, in response to determining that the first mobile device is authorized to make such a request, establishes the second network service. Further, in response to receiving, from a second mobile device, a request to join the second network service, which request includes the credential, the access point joins the second mobile device to the second network service and bridges traffic between the first and second mobile devices using the second network service.
