IP Message Bandwidth Negotiation via Multiplex Header Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP message transmission methods in communication systems face issues with unreliable bandwidth negotiation, resource wastage, and inefficiencies in data transmission due to lack of sender information in multiplex headers and excessive CRC checks, leading to frequent re-negotiations and communication breakdowns.
Innovation Solution
A method and apparatus for negotiating multiple bandwidth saving capabilities and constructing IP messages with multiplex headers containing sender information and improved length indicators, eliminating CRC checks on UP headers, and using protocols like H.248, IPBCP, SIP, and SDP for efficient bandwidth management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional IP message transmission is used without sender information in multiplex headers, then bandwidth is saved, but transmission reliability deteriorates due to inability to determine valid sender information
Solution Approach 1:
The patent segments the IP message structure by introducing a multiplex header that separates sender identification information from the main data payload. This allows the sender information to be efficiently transmitted without significantly increasing overall bandwidth consumption, while simultaneously enabling the receiver to validate message sources and improve transmission reliability.
2Reliability
If CRC check is performed on UP header, then data integrity is improved, but processing complexity and time increase
Solution Approach 1:
The patent extracts the CRC check operation from the UP header processing by implementing CRC verification at the IP header level instead. This separation allows the UP header to be processed more quickly without the overhead of CRC calculation, while data integrity is still maintained through IP-level CRC validation, thereby improving processing efficiency.
3Ease of operation
If bandwidth saving capability is negotiated using single capability indication, then negotiation simplicity is improved, but negotiation reliability deteriorates due to frequent re-negotiations
Solution Approach 1:
The patent implements dynamic bandwidth saving capability negotiation by allowing the sender to indicate multiple supported capabilities in the multiplex header. The receiver can then select the most appropriate capability based on current network conditions and its own capabilities, making the negotiation process both simple and reliable without requiring frequent re-negotiations.
4Adaptability or versatility
If multiple bandwidth saving capabilities are negotiated, then adaptability is improved, but negotiation complexity increases
Solution Approach 1:
The patent applies preliminary action by having the sender pre-indicate multiple supported bandwidth saving capabilities in the multiplex header before actual data transmission. This allows the receiver to make an informed selection based on its own capabilities and current network conditions, achieving high adaptability without increasing negotiation complexity during the actual communication process.
