DPP Network Configuration Filtering for Multiple AP Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Device Provisioning Protocol (DPP) technology does not specify how to provide connection information for multiple Access Points (APs) and does not clarify which AP's connection information is being provided to an enrollee client.
Innovation Solution
An electronic device is equipped with a communication circuit and processor to receive a request for network configuration information, apply a filtering scheme to select appropriate information, and transmit it to an external device, or perform authentication to receive selected network configuration information from an external device based on a filtering scheme.

Engineering Contradiction Analysis
1Adaptability or versatility
If connection information for multiple APs is provided to an enrollee client, then the enrollee client can connect to any of the multiple APs, but it becomes ambiguous which AP's connection information is being provided
Solution Approach 1:
The connection information for multiple APs is segmented into separate information elements, each uniquely identified by an AP identifier. This allows the enrollee client to distinguish between different APs while receiving comprehensive connection information for all of them.
Solution Approach 2:
A configurator device acts as an intermediary between the APs and the enrollee client. The configurator collects connection information from multiple APs, attaches appropriate identifiers to each, and delivers them to the enrollee client, thereby resolving the ambiguity of which AP's information is being provided.
2Ease of operation
If DPP technology provides simple device provisioning, then device connection is simplified, but it lacks specification for handling multiple APs with unique connection information
Solution Approach 1:
The DPP protocol is extended with multi-functionality to handle both single AP and multiple AP scenarios. The same basic provisioning mechanism is used, but enhanced with the capability to attach and manage multiple sets of connection information with unique identifiers, maintaining simplicity while adding complexity handling.

An electronic device is provided. The electronic device includes a communication circuit and at least one processor, and the at least one processor may be configured to receive, from an external electronic device via the communication circuit, a first message requesting network configuration information, select at least one network configuration information to be transmitted to the external electronic device among a plurality of network configuration information stored in the electronic device based on a set filtering scheme, and transmit, to the external electronic device via the communication circuit, a second message including the selected at least one network configuration information.
