Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transmitting multimedia services over packet-switched networks, such as UMTS, GSM, and CDMA, do not provide the quality of service expected from circuit-switched networks, necessitating an improvement in packet-switched network performance.
Innovation Solution
A system and method for efficient transmission of voice and data over internet protocol networks involve detecting next nodes, creating channels, merging packets of the same protocol, and routing them based on available bandwidth, utilizing an internet trunking protocol node with a channel interface, processor, and memory to manage packet transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If packet-switched networks are used to provide multimedia services, then network flexibility and scalability are improved, but quality of service deteriorates compared to circuit-switched networks
Solution Approach 1:
The patent segments the packet transmission process into distinct phases: packetization at the source, merging at intermediate nodes, and channel-based routing. This segmentation allows packet-switched networks to maintain flexibility while introducing circuit-switched-like quality guarantees through dedicated channels for different service types.
Solution Approach 2:
The patent introduces an intermediary merging node that acts as a mediator between packet sources and destinations. This node merges packets from multiple sources into consolidated streams, providing traffic shaping and quality of service enforcement, thereby bridging the gap between packet-switched flexibility and circuit-switched reliability.
2Adaptability or versatility
If multiple packets are transmitted separately over packet networks, then network routing flexibility is improved, but transmission efficiency deteriorates due to redundant headers and protocol overhead
Solution Approach 1:
The patent merges multiple packets of the same protocol into a single consolidated packet stream at intermediate nodes. This merging reduces the number of individual packet transmissions, eliminating redundant protocol headers and improving overall transmission efficiency while maintaining routing flexibility through channel-based forwarding.
3Productivity
If packet merging is implemented to improve transmission efficiency, then bandwidth utilization is improved, but protocol complexity increases
Solution Approach 1:
The patent applies packet merging selectively based on protocol type and traffic characteristics rather than universally. Different merging rules and channel assignments are applied to different protocol families (e.g., voice vs. data), reducing overall system complexity while maintaining high bandwidth utilization for each protocol category.
Data Source
AI summary
A method and system for efficient voice transmission over internet protocol networks is provided. A first node detects a next node, and a channel is created between the first node and the next node. A first packet is received at the first node and the protocol of the first packet is detected. The first packet is merged with a second packet having the same protocol as the first packet, and the merged first packet and second packet are transmitted to the next node via the channel.
