VoIP Advertisement Media System via SIP Call Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adoption of Voice over Internet Protocol (VoIP) services has been slow due to consumer comfort with the quality and cost of Public Switched Telephone Network (PSTN) services, lacking a compelling value proposition for transition.
Innovation Solution
A system that utilizes a Session Initiation Protocol (SIP) message to establish an Internet Protocol (IP) connection for presenting advertisement messages instead of ringback tones during calls, integrating with the Internet Protocol Multimedia Subsystem (IMS) network and Advertisement Media System (AMS) to offer free VoIP services by replacing traditional ringback tones with targeted advertisements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional PSTN services are used, then call quality and reliability are maintained, but service cost is high and adoption of VoIP remains slow
Solution Approach 1:
The patent introduces an advertisement media system as an intermediary between the calling party and the called party. During call setup, advertisement messages are delivered to the calling device, generating revenue that subsidizes the VoIP service. This mediator enables free or low-cost VoIP calls by compensating for infrastructure costs through targeted advertising, resolving the contradiction between maintaining service quality and reducing cost.
Solution Approach 2:
The patent extracts the revenue generation function from traditional telephony billing and places it in the advertisement delivery system. Instead of charging users for calls, the system separates the call transport function (handled by VoIP infrastructure) from the revenue model (handled by advertisement delivery), allowing free service while maintaining infrastructure costs through alternative funding.
2Productivity
If advertisement messages are delivered during call setup, then revenue is generated to support free VoIP service, but system complexity increases with additional components like AMS and SIP integration
Solution Approach 1:
The patent makes the Call Session Control Function (CSCF) multi-functional by integrating advertisement delivery capabilities into the existing SIP call setup process. The CSCF not only manages call signaling but also coordinates advertisement message delivery, eliminating the need for completely separate advertising infrastructure and reducing overall system complexity while maintaining revenue generation.
Solution Approach 2:
The patent merges the advertisement delivery system with the VoIP call control system. The advertisement media system integrates with the IMS network architecture, sharing common infrastructure elements such as the CSCF and signaling protocols. This consolidation reduces the number of independent systems required, lowering deployment complexity while preserving the revenue-generating advertisement functionality.
3Productivity
If targeted advertisements are delivered to calling devices, then consumer engagement and revenue potential increase, but user experience may be degraded by interrupting call setup
Solution Approach 1:
The patent delivers advertisement messages during the ringback tone period, which is a natural pause in the call setup process when the called party's device is ringing. This timing exploits an existing interval in the call flow rather than adding interruptions, maintaining user experience while delivering advertisements during a period when the calling user is already engaged and attentive.

AI summary
A system for deploying Voice over Internet Protocol (VoIP) services is provided. A system that incorporates teachings of the present disclosure may include, for example, a Call Session Control Function (CSCF) having a controller element to receive a Session Initiation Protocol (SIP)message from an originating communication device requesting communications with a terminating communication device, and establish an Internet Protocol (IP) connection between the originating communication device and an advertisement media system to present at the originating communication device an advertisement message that replaces a ringback tone associated with the terminating communication device. Additional embodiments are disclosed.
