Telephony Routing Engine for Accessibility Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telephony systems inadequately manage special routing procedures for accessibility users, requiring additional digit dialing and interactive voice response for operator services, which can be cumbersome for users with accessibility needs.
Innovation Solution
A routing engine and database combination in a key network location uses electronic number mapping or SIP redirect protocols to identify accessibility customer calls, replacing the invite message's R-URI with a special destination number, connecting users directly to operator services through designated peering points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If typical operator services are used with additional digit dialing and IVR communication, then service functionality is provided, but user effort and complexity increase
Solution Approach 1:
The system performs preliminary identification of accessibility users through source address analysis before the call reaches the operator services destination. By pre-determining the routing path based on the calling number's association with accessibility services, the system eliminates the need for additional digit dialing and IVR navigation, directly routing calls through designated peering points to operator services providers.
2Adaptability or versatility
If call routing is based only on call type, then general routing is simplified, but special routing procedures for accessibility users cannot be managed
Solution Approach 1:
The system applies different routing qualities to different source addresses. By analyzing the source address (calling number) to determine whether it is associated with accessibility services, the system applies specialized routing procedures only to relevant calls while maintaining standard routing for other calls. This localized differentiation enables special routing capability without requiring complete system redesign.
Solution Approach 2:
The patent introduces an intermediary routing mechanism that sits between the standard call routing system and the operator services provider. This intermediary component analyzes source addresses, determines accessibility service requirements, and redirects calls accordingly through designated peering points, enabling special routing without disrupting the general call routing infrastructure.
3Ease of operation
If accessibility users dial standard operator numbers, then service access is attempted, but additional digit dialing and IVR communication are required
Solution Approach 1:
The system performs preliminary identification of accessibility users through source address analysis before the call reaches the operator services destination. By pre-determining the routing path based on the calling number's association with accessibility services, the system eliminates the need for additional digit dialing and IVR navigation, directly routing calls through designated peering points to operator services providers.
Data Source
AI summary
Systems and methods for managing network communication are disclosed. Methods and systems can comprise receiving a telephony message having a source address and determining routing information using the source address. A telephony call may be routed using the determined routing information. Such processing may be implemented to route telephony calls to certain services such as accessibility services based on at least the source address of a telephony message.
