Wi-Fi Roaming via Virtual Access Point Cloning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wi-Fi enabled devices are underutilized due to the need for manual configuration and security setup when switching between Wi-Fi access points, leading to unused bandwidth and limited mobility in accessing internet services.
Innovation Solution
A system and method that enables Wi-Fi roaming by using a gateway with both local and virtual access points, where the virtual access point is accessible to both the device owner and roaming devices, with a datastore managing information to facilitate seamless connection without manual configuration, and a tunnel maintaining session continuity during roaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Wi-Fi access points are configured with security parameters and filters, then network security is improved, but device complexity and manual configuration requirements increase
Solution Approach 1:
The patent clones the virtual access point configuration including SSID, security parameters, and filtering rules from a source gateway to a target gateway. This copying mechanism allows the target gateway to inherit all security settings and access control policies without requiring manual reconfiguration, thus maintaining network security while eliminating configuration complexity.
Solution Approach 2:
The system performs preliminary configuration by pre-establishing the virtual access point with all security parameters, encryption keys, and filter rules before deployment. When the virtual AP is cloned to new gateways, these preliminary configurations are automatically transferred, eliminating the need for manual security setup at each location.
2Reliability
If manual configuration is required when switching between access points, then network security is maintained, but ease of operation deteriorates
Solution Approach 1:
When a Wi-Fi device roams to a new gateway, the virtual access point configuration is automatically cloned from the source gateway to the target gateway. This cloning process copies all security parameters, authentication credentials, and network settings, allowing the device to connect seamlessly without manual reconfiguration while maintaining security through identical parameter replication.
Solution Approach 2:
The system enables self-service roaming by automatically detecting when a device moves to a new gateway and initiating the cloning process without user intervention. The gateways autonomously exchange configuration data and authenticate the roaming device, eliminating manual configuration steps while maintaining security through automated parameter replication.
3Reliability
If Wi-Fi devices are restricted to home networks only, then network security is improved, but adaptability deteriorates
Solution Approach 1:
The virtual access point is designed with universal functionality that allows it to be deployed across multiple gateways and locations while maintaining consistent security parameters. The cloning mechanism enables the same virtual AP configuration to operate securely across different physical locations, allowing Wi-Fi devices to access networks both at home and while roaming without compromising security.
Solution Approach 2:
The system copies the authenticated virtual access point configuration from home gateways to roaming gateways, enabling Wi-Fi devices to access networks outside their home environment. This copying process ensures that the same security parameters and authentication mechanisms are applied consistently across different locations, providing both adaptability and security.
4Productivity
If gateways are deployed throughout a service area to enable roaming, then productivity is improved, but device complexity increases
Solution Approach 1:
The system automatically clones virtual access point configurations from source gateways to target gateways deployed throughout the service area. This cloning process replicates all necessary configuration parameters, security settings, and access control policies, enabling multiple gateways to operate with consistent configurations without requiring manual setup at each location, thus improving bandwidth utilization while managing complexity.
Solution Approach 2:
The virtual access point configuration is preliminarily established at a source gateway with all necessary parameters and security settings. When additional gateways are deployed for roaming coverage, the configuration is automatically copied from this pre-configured source, eliminating the need for complex manual configuration at each new location and enabling rapid deployment of extended network coverage.
Data Source
AI summary
Systems and methods for cloning a Wi-Fi access point. A determination is made by a network monitoring device to transition communications between a Wi-Fi device and a first access point (AP) to a second AP. The SSID and the security configuration information, and, optionally, network address translation (NAT) information of the first access point are acquired and provided to a second AP. The second AP instantiates the SSID and the security configuration information and, optionally, the NAT information. The networking monitoring device directs the first AP to cease using the SSID and the security configuration information and, optionally, the NAT information in response to receipt of confirmation that the second AP has instantiated the SSID and the security configuration information and, optionally, the NAT information of the first AP.
