Network Device Call Routing Security Level Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a complex environment of interconnected networks, telecommunications service providers face increased costs and technical complexities when calls are initiated over multiple network types, requiring frequent conversions between different network types such as PSTN and VoIP networks.
Innovation Solution
A method that involves receiving an identifier for a called party, determining the security levels of the networks associated with the party, querying a database to identify suitable networks, and automatically selecting a network with a matching or higher security level to complete the call, thereby eliminating the need for format changes between network types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If calls are initiated over multiple network types (PSTN, VoIP), then consumers have more service options and flexibility, but the costs and technical complexities of connecting such calls increase for service providers
Solution Approach 1:
The patent introduces a network device as an intermediary that receives calls from one network type and routes them to appropriate network types for completion. This mediator handles the complexity of network conversions centrally, allowing consumers to access multiple network services while reducing the technical burden on individual call connections.
Solution Approach 2:
The system dynamically determines routing parameters based on network security levels and call characteristics. By changing routing decisions based on security level parameters, the system optimizes call completion while managing technical complexities through automated parameter-based routing logic.
2Adaptability or versatility
If calls are carried by more than one type of network, then more service options are available to consumers, but the costs for service providers increase
Solution Approach 1:
The system performs preliminary network assessment and security level determination before call completion. By pre-evaluating network security levels and routing options, the system can make cost-optimal routing decisions in advance, reducing unnecessary network conversions and associated costs while maintaining service options.
Solution Approach 2:
The network device autonomously determines routing decisions based on security level comparisons without requiring manual intervention. This self-service routing approach optimizes cost efficiency by automatically selecting the most appropriate network path based on predefined security criteria.
3Adaptability or versatility
If format conversions are performed between network types, then calls can be completed across different networks, but technical complexities and costs increase
Solution Approach 1:
The network device serves as an intermediary that handles format conversions between different network types (PSTN, VoIP, cellular). By centralizing conversion functions in this mediator device, the system maintains network compatibility while reducing the complexity of individual call routing decisions.
Solution Approach 2:
The patent segments the call routing process into distinct functional components: receiving the call, determining network security levels, comparing security levels, and routing to the appropriate network. This segmentation simplifies the overall technical complexity by breaking down the conversion and routing process into manageable stages.
Data Source
AI summary
The disclosed embodiments include a method of initiating a call. The method includes receiving, at a network device over a first network, an identifier associated with a called party. The method determines a first security level associated with the first network and identifies a plurality of networks associated with the called party using the identifier. The method queries a database to determine a second security level for each network in the plurality of networks and automatically selects an identified network from the plurality of networks associated with the called party having the second security level at least equal to the first security level. The method completes a call to the called party using the identified network.
