Bluetooth Mesh Provisioner Authority Sharing via P2P Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Bluetooth mesh networks, sharing control authority between provisioner nodes is challenging when devices cannot connect to the cloud or have different accounts, limiting efficient network management.
Innovation Solution
A Bluetooth mesh network system and method that allows an original provisioner node to store and broadcast control authority information, enabling newly added provisioner nodes to establish a one-to-one connection, request, and receive this information to control the network independently, without requiring external network access or shared accounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cloud sharing service is used to share control authority, then control authority can be shared among devices, but the system fails when devices cannot connect to cloud service or have different accounts
Solution Approach 1:
The patent introduces a direct peer-to-peer connection as an intermediary mechanism between provisioner nodes, eliminating dependence on external cloud services. The connection protocol enables devices to exchange control authority information directly through Bluetooth Low Energy communication, serving as a reliable mediator that works independently of network connectivity status.
Solution Approach 2:
The system enables provisioner nodes to autonomously establish connections and transfer control authority without requiring external cloud service mediation. Devices use their own Bluetooth resources and connection protocols to self-manage the authority sharing process, making the system self-sufficient and independent of external infrastructure.
2Ease of operation
If one provisioner node controls the whole network, then network management is centralized, but multiple devices cannot efficiently control the network simultaneously
Solution Approach 1:
The patent implements a dynamic control authority model where provisioner nodes can be added or removed from the network at any time. The control authority is not fixed to a single device but can be dynamically transferred between provisioner nodes through the connection protocol, allowing the network management structure to adapt flexibly to changing requirements.
Solution Approach 2:
The connection protocol designed in the patent serves multiple functions: it enables initial device pairing, facilitates control authority transfer, and maintains ongoing network management capabilities. This universal protocol allows any provisioner node to perform all necessary network control operations, making the system universally adaptable to different control scenarios.

AI summary
The present invention discloses a Bluetooth mesh network system having control authority sharing mechanism that includes an original provisioner node and at least one newly added provisioner node. The original provisioner node stores control authority information related to a Bluetooth mesh network, controls the Bluetooth mesh network accordingly and performs a control authority broadcast. The newly added provisioner node receives the control authority broadcast and establishes connection with the original provisioner node according to a connection protocol. The newly added provisioner node further requests the control authority information from the original provisioner node so as to control the Bluetooth mesh network after receiving the control authority information from the original provisioner node.
