Solution Overview

Problem

Current SIP-based services in IP Multimedia Subsystems (IMS) lack an effective method to integrate and deliver advertisements to users within the existing signaling protocols, limiting the ability to provide versatile and targeted advertising services.

Innovation Solution

A method is introduced where advertising information is inserted into SIP signaling messages, allowing for the delivery of advertisements to users by intercepting and modifying SIP messages within the IMS network, using an Advertisement Application Server (Ad AS) that inserts advertising content into SIP messages and sends them to target terminals, ensuring that users who have subscribed to advertising services receive relevant advertisements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If advertising information is inserted into SIP signaling messages, then advertising delivery capability is improved, but signaling message complexity increases

Engineering Contradiction:

Improveadvertising delivery capabilityVSAvoidsignaling message complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent embeds advertising information within existing SIP message structures by inserting advertisement headers into the SIP message body. This nesting approach allows advertising functionality to be integrated without creating separate message formats, thereby improving advertising delivery capability while minimizing the increase in signaling message complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent makes SIP signaling messages multi-functional by enabling them to carry both original signaling data and advertising information. The advertisement headers are inserted into existing SIP message fields, allowing the same message structure to serve both signaling and advertising purposes, thus improving versatility without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If advertising information is inserted into SIP signaling messages, then user engagement is improved, but message processing time increases

Engineering Contradiction:

Improveuser engagementVSAvoidmessage processing time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies partial action by inserting advertising information only into specific fields of SIP messages where it does not significantly impact processing time. The advertisement headers are placed in a manner that allows for efficient parsing and processing, ensuring that user engagement is improved while the increase in message processing time is minimized.

Inventive Principle:

Principle #16Partial or excessive action

3Productivity

If advertising service is integrated into IMS, then revenue opportunities are improved, but network infrastructure complexity increases

Engineering Contradiction:

Improverevenue opportunitiesVSAvoidnetwork infrastructure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges advertising functionality with existing IMS and SIP infrastructure by integrating advertisement headers into standard SIP message processing flows. This combining approach allows advertising services to be delivered using existing network elements and protocols, thereby improving revenue opportunities while minimizing the increase in network infrastructure complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Disclosure may be to allow a Service Provider (or operator) to intercept SIP messages (e.g., SIP INVITE method, or SIP MESSAGE method) in the path of the IMS signaling link and insert advertising information therein, thereby delivering the advertising information inserted in the SIP messages to one or more end users (i.e., originating end or terminating end, or all of them).
