PAPL Module Intercepts SIP Messages to Reduce Call Charges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems lack an effective solution for providing advertising-supported call services, particularly for international calls that are often expensive and have low call volume and duration due to high billing by the minute.
Innovation Solution
The implementation of a Play Advertisement Pay Less (PAPL) service that intercepts SIP call setup messages to determine subscriber eligibility, plays advertisements to callers, and reduces call charges by using a PAPL module within a communications network, including a communications module, PAPL module, and computer-readable media to control the call setup and charging processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional billing by the minute is used for international calls, then call service is provided, but call cost is high and call volume is low
Solution Approach 1:
The patent introduces an advertisement intermediary as a mediator between the calling subscriber and the called subscriber. During the call setup process, an advertisement is played to the calling subscriber, and in exchange, the call charge is reduced. This intermediary mechanism (advertisement playback) enables a new pricing model that makes international calls more affordable while generating revenue through advertising, thereby increasing call volume without compromising service quality
Solution Approach 2:
The patent changes the pricing parameter from traditional time-based billing to advertisement-supported billing. By playing advertisements during call setup, the system transforms the cost structure, allowing reduced call charges for subscribers who accept advertising content. This parameter change directly addresses the contradiction by making calls more affordable while maintaining service quality and increasing call volume
2Ease of manufacture
If advertising is used to subsidize media delivery, then cost reduction is achieved, but no acceptable solution for call service exists
Solution Approach 1:
The patent applies the universality principle by adapting the advertisement subsidy model from traditional media (radio, television) to telecommunications call service. The system integrates advertisement playback into the call setup process, making the advertising-supported model universally applicable to voice calls. This multi-functionality approach allows the same advertising mechanism to serve both media delivery and telecommunication services, achieving cost reduction while maintaining service applicability
Solution Approach 2:
The patent implements preliminary action by playing advertisements during the call setup phase before the actual call begins. This preliminary advertisement delivery allows the system to subsidize the call cost in advance, making the advertising-supported model work effectively for call service. The advertisement is delivered as a preliminary action that enables subsequent reduced-charge calling
3Ease of manufacture
If advertisement is played during call setup, then call charge is reduced, but call setup time is extended
Solution Approach 1:
The patent applies periodic action by playing advertisements in a time-efficient manner during call setup. The advertisement playback is implemented as a periodic or interruptible process that occurs within the existing call setup timeframe, rather than adding significant delay. This allows the system to reduce call charges through advertisement support while minimizing the time penalty during call establishment
Data Source
AI summary
Methods, systems, and computer readable media for advertising-supported call service are disclosed. According to one method, a SIP call setup message associated with a first call from a calling subscriber to a called subscriber is received. It is then determined whether the calling subscriber subscribes to a play advertisement pay less (PAPL) service. In response to determining that the calling subscriber subscribes to the PAPL service, an advertisement is presented to the calling subscriber via the subscriber's telephone, the call is connected to the called subscriber, and a reduced charge is effected for the call based on the PAPL service.
