Solution Overview

Problem

Existing methods for provisioning extended service set identifiers (ESSIDs) in wireless local area networks (WLANs) require manual data entry by users, which is cumbersome, and existing solutions do not efficiently allow the WLAN to automatically provision mobile devices with the necessary ESSID for initial connection.

Innovation Solution

A mobile communication device associates with a provisioning virtual local area network (VLAN) using a provisioning ESSID, allowing it to receive and store a primary ESSID from the WLAN after authentication, enabling subsequent communications with the WLAN using the primary ESSID.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual data entry is used to provision ESSID, then the device can be configured, but the process is cumbersome and time-consuming

Engineering Contradiction:
ImproveESSID provisioning processVSAvoidTime required for ESSID entry
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The mobile device automatically obtains the ESSID from the WLAN network through the provisioning VLAN, eliminating the need for manual user input. The device provisions itself by receiving the primary ESSID from the access point during the authentication process.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The WLAN network pre-configures the primary ESSID and makes it available through the provisioning VLAN before the mobile device needs to connect to the primary network. The access point is prepared in advance to provide the ESSID information to authorized devices.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the WLAN automatically provisions the mobile device with ESSID, then data entry is minimized, but the mobile device needs the ESSID to initially connect with the WLAN

Engineering Contradiction:
ImproveAutomatic ESSID provisioningVSAvoidConnection establishment process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A provisioning VLAN acts as an intermediary network between the mobile device and the primary WLAN network. The mobile device first connects to the provisioning VLAN using a known provisioning ESSID, which then facilitates the transfer of the primary ESSID information from the access point to the mobile device.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The network is segmented into two distinct VLANs: a provisioning VLAN for initial connection and ESSID distribution, and a primary VLAN for actual service access. This segmentation allows the device to connect through different network paths for different purposes.

Inventive Principle:
Principle #1Segmentation

3Extent of automation

If a provisioning VLAN is introduced for ESSID distribution, then automatic provisioning is enabled, but the network structure becomes more complex

Engineering Contradiction:
ImproveESSID provisioning automationVSAvoidNetwork structure
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The provisioning VLAN and provisioning ESSID serve multiple functions: they enable initial device connection, facilitate secure authentication, and distribute the primary ESSID information. This multi-functionality reduces the need for separate mechanisms for each task.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements an authentication feedback mechanism where the access point verifies the mobile device's credentials against the provisioning server, and only after successful authentication does the access point provide the primary ESSID. This feedback loop ensures security while automating the provisioning process.

Inventive Principle:
Principle #23Feedback

AI summary

Methods and apparatus for use in provisioning mobile communication devices in wireless local area networks (WLANs) are described. In one illustrative example, a mobile communication device associates with a wireless access point of a provisioning virtual local area network (VLAN) of the network with use of a provisioning network identifier ("provisioning ESSID"). After associating with the wireless access point of the provisioning VLAN, a primary network identifier ("primary ESSID") associated with a primary VLAN of the network is received from the WLAN in a provisioning procedure and stored in memory of the mobile device after authentication. For subsequent communications with the WLAN, the mobile device associates with a wireless access point of the primary VLAN of the network with use of the primary network identifier.
