VoIP Docking Station VPN Routing for Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications networks face high costs when carrying phone calls using Public Switched Telephone Networks (PSTN), while Voice over Internet Protocol (VoIP) incurs minimal costs for data transmission, but requires efficient routing to minimize PSTN usage for cost reduction.
Innovation Solution
A docking station with VoIP capabilities sets up multiple Virtual Private Networks (VPNs) and maps application types to specific network addresses, allowing mobile devices to route VoIP traffic via the most cost-effective network paths, utilizing Network Address Translation (NAT) or bridging modes for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If VoIP is used to carry calls via Internet, then call cost is reduced, but network routing complexity increases to minimize PSTN usage
Solution Approach 1:
The patent segments network routing into multiple Virtual Private Networks (VPNs), each dedicated to specific application types. The docking station creates separate VPNs for different applications and manages routing decisions based on application type, thereby reducing overall routing complexity while maintaining cost efficiency through specialized network paths.
Solution Approach 2:
The docking station acts as an intermediary between mobile devices and networks. It receives routing decisions from the mobile device, establishes appropriate VPN connections, and forwards traffic through the most cost-effective network paths, simplifying the routing complexity management while maintaining VoIP cost reduction benefits.
2Reliability
If multiple VPNs are set up for different applications, then network efficiency and security are enhanced, but device complexity increases
Solution Approach 1:
The docking station provides universal VPN management functionality that serves multiple applications simultaneously. It maintains a centralized VPN configuration that can be reused across different applications, reducing the overall complexity burden while still providing secure, efficient network paths for each application type.
Solution Approach 2:
The mobile device autonomously determines routing decisions based on application type and communicates these to the docking station. The docking station then automatically establishes appropriate VPN connections without requiring complex manual configuration, thereby reducing management complexity while maintaining network efficiency and security.
3Measurement precision
If application types are mapped to specific network addresses, then traffic routing precision is improved, but system complexity increases
Solution Approach 1:
The patent implements local quality by creating application-specific VPN configurations with tailored network addresses and routing parameters. Each application receives customized network parameters optimized for its specific needs, improving routing precision while the modular nature of these local configurations keeps system complexity manageable.
Data Source
AI summary
A device includes a memory that stores multiple different types of applications and a data table, and a processing unit. The processing unit is configured to receive configuration data that sets up multiple network interfaces on the device, and assigns one of multiple different network addresses to each of the multiple network interfaces, store the configuration data in the data table, execute a first type of application of the multiple different types of applications, receive one or more first packets from executing the first type of application of the multiple different types of applications, retrieve a first Virtual Private Network (VPN) identifier associated with a first VPN from the data table based on the first type of application of the multiple different types of applications, and send the one or more first packets via the first VPN identified by the first VPN identifier.
