Call Intercept Unit for Early Media Delivery in IP Telephony
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP telephony systems lack the ability to provide tailored or advanced information to communicants as early media before a telephony communication is established, limiting the potential for informed decision-making by callers regarding call setup, such as notification of rate changes.
Innovation Solution
The implementation of a call intercept unit within IP telephony systems that determines when to play messages or provide information to calling or called parties using a message generation and storage unit, allowing for early media delivery based on various factors, including rate changes, and tracks message delivery to prevent repetition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If early media is played to calling or called parties before telephony communication is established, then informed decision-making by callers is improved, but device complexity increases due to need for intercept determination logic
Solution Approach 1:
The system performs preliminary actions by determining whether to play early media before the telephony communication is actually established. The intercept determination unit evaluates criteria (such as caller identity, called party information, or call characteristics) and decides in advance whether to deliver tailored messages or information to the calling or called party, enabling informed decision-making before the call connects.
2Adaptability or versatility
If tailored messages are delivered based on calling or called party information, then adaptability is improved, but measurement precision requirements increase for tracking message delivery
Solution Approach 1:
The system implements feedback mechanisms to track whether early media messages have been played to calling or called parties. The message tracking unit monitors message delivery and provides feedback to the intercept determination unit, which uses this information to determine whether to play additional messages or to wait for the telephony communication to establish before delivering information.
3Reliability
If message tracking is implemented to prevent repetition, then reliability is improved, but device complexity increases
Solution Approach 1:
The message tracking unit operates autonomously to monitor and track whether early media messages have been delivered to calling or called parties. It maintains its own records of message delivery status and provides feedback to the intercept determination unit without requiring external intervention, enabling reliable prevention of message repetition through self-service tracking.

AI summary
During setup of a telephony communication between a calling and a called party, a check is made to determine is a special message or information should be played to the calling or called party before the telephony communication is established between the calling and called parties. If so, the message or information is delivered to the party as early media. Systems and methods embodying the invention may track which messages and information have been played to individual parties to thereby avoid delivering the same message or information more than once.
