Gateway Transfer System for Voice Portal Call Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice portals often experience unavailability issues, leading to call delays and failed transfers between networks, as gateways lack mechanisms to handle failed calls and route them back to the originating network, especially in circuit-switched telephone networks.
Innovation Solution
A gateway transfer system that utilizes DNIS and ANI information to map failed calls to alternate destinations, prioritizing based on geographical location, time, and utilization, with modules for monitoring, mapping, and transferring calls to reduce wait times and handle priority calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gateway transfers a call to a voice portal in a second network, then the call can be handled by the voice portal, but the call may experience significant delays or fail if the voice portal is unavailable
Solution Approach 1:
The gateway performs preliminary actions by monitoring the availability status of the voice portal before completing the call transfer. When the voice portal becomes available, the gateway proactively initiates the transfer, preventing unnecessary delays. This preliminary monitoring and conditional transfer mechanism resolves the contradiction by ensuring reliable transfer only when the destination is ready, eliminating both failed transfers and unnecessary waiting.
2Productivity
If the gateway monitors and reroutes failed calls to alternate destinations, then call handling efficiency improves, but the system complexity increases
Solution Approach 1:
The gateway introduces an intermediary mechanism in the form of a monitoring module that acts as a mediator between the call transfer process and the voice portal availability status. This intermediary continuously checks the destination's readiness and controls the transfer timing, thereby improving call handling efficiency without requiring complex changes to the core gateway architecture. The intermediary absorbs the complexity of availability management, keeping the main system simple while achieving high productivity.

AI summary
A system for and method of providing a gateway transfer mechanism is presented. In one exemplary embodiment, the system and method of providing a gateway transfer mechanism may be realized as a method, comprising identifying, at a gateway, a call to be routed to a first location, determining whether to transfer the call to a second location, in the event the call is to be transferred to the second location, transferring the call, wherein transferring the call comprises ending a process to route the call to the first location, generating transfer information for the second location, and transferring the call to the second location using the generated transfer information.
