Dialed Digit Filter System for Call Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network configurations waste resources on unsuccessful call attempts due to unnecessary validation checks for invalid or unavailable dialed numbers, tying up radio frequency, transport, and media resources.
Innovation Solution
Implementing a dialed digit filter system that checks dialed numbers against a database before utilizing network resources, allowing or prohibiting calls based on the status and providing announcements for invalid numbers, thereby reducing resource utilization for unsuccessful calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the provider network processes all call requests through multiple network devices, then call validation and routing are ensured, but network resources are wasted on invalid or unavailable numbers
Solution Approach 1:
The patent implements a preliminary check mechanism that queries a database of invalid or unavailable numbers before the call request is fully processed by the network devices. This preliminary action filters out invalid calls in advance, preventing unnecessary consumption of radio frequency, transport, and media resources while maintaining reliable validation for legitimate calls.
2Measurement precision
If validation checks are performed for all dialed numbers, then call routing accuracy is maintained, but resource consumption increases for unsuccessful calls
Solution Approach 1:
The patent extracts the validation check function from the main call processing flow and implements it as a separate preliminary query against a database of invalid numbers. This separation allows the main network devices to focus on routing accurate calls while the extracted validation function efficiently filters out invalid numbers, improving both routing accuracy and resource efficiency.
3Ease of operation
If the network processes unsuccessful call attempts, then complete call handling is provided, but radio frequency and transport resources are tied up unnecessarily
Solution Approach 1:
The patent applies preliminary anti-action by proactively identifying and blocking calls to invalid or unavailable numbers before they can consume radio frequency and transport resources. The system pre-loads a database of known invalid numbers and performs quick lookups to prevent unsuccessful call attempts, thereby maintaining ease of operation for valid calls while reducing overall resource utilization.
Data Source
AI summary
A method may include determining that a digit pattern has been input on a user device to initiate a call; transmitting the digit pattern to a device that stores a list of digit patterns to which calls are not to be completed; receiving, from the device, data that indicates whether the digit pattern is on the list of digit patterns; prohibiting the call from being initiated with a network when the data indicates that the digit pattern is on the list of digit patterns; and initiating the call with the network when the data indicates that the digit pattern is not on the list of digit patterns.
