Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IMS architectures face challenges in efficiently supporting advanced multimedia services due to limited capabilities of Service Point Triggers (SPTs), which are insufficient for new terminal types and services like presence and streaming video, leading to difficulties in introducing new services in cellular architectures.
Innovation Solution
A multimedia communication system that includes a programmable flow engine, rules engine, and service enablers with policy hooks, allowing for dynamic invocation of application servers based on signaling messages and control data, enabling flexible deployment of new services without hard-coding logic in the Application Control Point or Access Terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional IMS architecture with Service Point Triggers is used, then basic telephony services are supported, but advanced multimedia services cannot be efficiently introduced
Solution Approach 1:
The patent segments the monolithic switching center into separate functional components: the Access Terminal with its own processing capabilities, and the network core with streamlined functionality. This segmentation allows services to be distributed and introduced independently without redesigning the entire switching center architecture.
Solution Approach 2:
The patent introduces an intermediary processing layer at the Access Terminal that mediates between the terminal device and the network core. This intermediary enables local service processing and decision-making, facilitating flexible service introduction without requiring changes to the core network switching center.
2Adaptability or versatility
If Service Point Triggers are used to invoke application servers, then service routing is achieved, but the capability is insufficient for new terminal types and advanced services
Solution Approach 1:
The patent implements dynamic service processing capabilities at the Access Terminal that can adapt to different terminal types and service requirements in real-time. The terminal can dynamically invoke local services and make routing decisions based on current conditions, rather than relying on static Service Point Trigger configurations.
Solution Approach 2:
The patent enables preliminary service processing and decision-making to occur at the Access Terminal before requests reach the network core. The terminal can pre-evaluate service requirements, invoke appropriate local services, and make routing decisions in advance, improving both adaptability to new terminal types and reliability of service support.
3Productivity
If new services are introduced in traditional cellular architectures, then service functionality is added, but difficulty and expense increase due to monolithic switching center design
Solution Approach 1:
By segmenting service functionality between the Access Terminal and network core, the patent enables independent deployment of services at the terminal level. This eliminates the need for expensive and complex switching center modifications for each new service, significantly reducing deployment costs and increasing productivity.
Solution Approach 2:
The patent enables the Access Terminal to self-provision and execute services locally without requiring extensive network infrastructure changes. The terminal can independently invoke services, process requests, and manage local resources, making service introduction straightforward and cost-effective.
