Softswitch Call Routing via Customer Handling Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition from legacy circuit switched networks to softswitch managed networks faces challenges in providing unique call handling for customers, as there is no equivalent device in softswitch networks to store customer-specific information, leading to the need for a system that can handle calls without requiring multiple network interfaces.
Innovation Solution
A system comprising a call management device and a redirect server that uses a unique customer handling parameter to determine customized call routing, allowing for differentiated routing partitions to provide specific call handling requirements, thereby enabling efficient and confidential customer-specific call management without the need for extensive network interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legacy circuit switched networks are used to store customer-specific information at switches, then unique call handling for customers is achieved, but device complexity and network infrastructure requirements increase
Solution Approach 1:
The patent extracts customer-specific information handling from the circuit switched network switches and relocates it to the softswitch. The softswitch receives signaling messages, determines customer handling parameters, queries routing partitions for differentiated routing information, and manages call routing based on customer-specific requirements. This extraction eliminates the need for customer-specific information storage at multiple switches while maintaining unique call handling capabilities.
Solution Approach 2:
The softswitch serves as a universal call management device that handles both generic call routing and customer-specific call handling through a single interface. By implementing the customer information determination and routing decision logic within the softswitch, the system provides multi-functional capability without requiring separate specialized devices for each customer type, thereby reducing overall network infrastructure complexity.
2Adaptability or versatility
If multiple network interfaces are provisioned to provide unique call handling, then customer-specific call handling requirements are met, but device complexity and number of nodes increase
Solution Approach 1:
The patent segments the routing information storage and retrieval function into separate routing partitions within the softswitch. Each routing partition contains differentiated routing information for specific customer groups or handling requirements. This segmentation allows the softswitch to efficiently query and retrieve appropriate routing information without requiring multiple physical network interfaces or nodes, as all routing intelligence is consolidated within the softswitch's memory structures.
Solution Approach 2:
The softswitch acts as an intermediary between the signaling message input and the call routing output. It receives signaling messages containing customer identification information, determines the appropriate customer handling parameter, queries the routing partitions for differentiated routing information, and generates the final routing decision. This intermediary role consolidates multiple functions into a single node, eliminating the need for multiple network interfaces while maintaining call handling differentiation.
3Adaptability or versatility
If customer-specific information is stored at each switch, then unique call handling is achieved, but information confidentiality and security increase due to multiple access points
Solution Approach 1:
The patent extracts customer-specific information handling from distributed switches and consolidates it at the softswitch. The softswitch receives signaling messages, determines customer handling parameters, and queries routing partitions for differentiated routing information. This extraction reduces the number of access points to customer information from multiple switches to a single secure location, thereby reducing information security risks while maintaining customized call routing capabilities.
