Link 16 Relay Transmission With Multi-Message Timeslot Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased demand for message relay capability in MIDS-JTRS Link 16 networks due to enhanced receiving capabilities has led to a significant burden on nodes and a reduction in available communication timeslots, necessitating a larger number of relay terminals and timeslots.
Innovation Solution
Enhancing MIDS-JTRS terminals to package multiple conventional Link 16 messages into a single high-bandwidth Enhanced Throughput (LET) message, allowing transmission and relay of these messages within a single timeslot without increasing the number of relay terminals or timeslots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple conventional Link 16 messages are transmitted separately in individual timeslots, then message relay capability is provided, but the number of required relay terminals and timeslots increases significantly
Solution Approach 1:
The patent combines multiple conventional Link 16 messages into a single LET message format, allowing multiple messages to be transmitted together in one timeslot. This merging approach consolidates what would otherwise require multiple separate transmissions and relay terminals into a single unified transmission, directly reducing the number of relay terminals and timeslots needed while maintaining full message relay capability.
Solution Approach 2:
The patent introduces a new message packaging dimension by encapsulating multiple conventional messages within a single LET message structure. This dimensional transformation allows the system to handle multiple messages simultaneously in what would traditionally be a single-message timeslot, effectively increasing message relay capacity without proportionally increasing the number of timeslots or relay terminals required.
2Productivity
If the number of relay terminals is increased to handle enhanced receiving capabilities, then message relay capability improves, but the burden on nodes and reduction in available communication timeslots worsens
Solution Approach 1:
By merging multiple messages into a single LET message transmitted in one timeslot, the patent reduces the total number of timeslots required for message relay. This consolidation frees up communication timeslots that would otherwise be consumed by separate message transmissions, thereby reducing the loss of available communication timeslots while maintaining enhanced message relay capability.
Solution Approach 2:
The patent enables continuous efficient use of communication timeslots by allowing each timeslot to carry multiple messages simultaneously. This maximizes the utilization of each timeslot for useful communication activity, reducing the overall time required for message relay and minimizing the impact on available communication timeslots for other purposes.
3Adaptability or versatility
If conventional Link 16 message format is used, then compatibility with existing systems is maintained, but message transmission efficiency and relay capacity are limited
Solution Approach 1:
The LET message format serves as an intermediary structure that bridges conventional Link 16 message compatibility and enhanced transmission efficiency. The packaging protocol acts as a mediator, allowing multiple conventional messages to be encapsulated in the LET format for efficient transmission, then unpacked back to their original form for compatibility with existing systems. This intermediary approach enables both high message transmission efficiency and full system compatibility simultaneously.
Solution Approach 2:
The patent segments the message transmission process into three distinct phases: packaging multiple conventional messages into a single LET message for efficient transmission, transmitting the consolidated LET message through the channel, and unpacking the received LET message back into individual conventional messages. This segmentation allows the system to achieve high transmission efficiency during the transmission phase while maintaining compatibility with existing systems during the packaging and unpacking phases.

AI summary
A method of transmitting and receiving a plurality of Link 16 messages on a single subnet in a single timeslot includes a transmitting terminal packaging the Link 16 messages into an envelope enhanced throughput message (envelope LET message) and transmitting the envelope LET message to a receiving terminal, followed by the receiving terminal unpacking the Link 16 messages from the envelope LET message, restoring them to their original form, and presenting them to a host. Modification of the host is not required. The Link 16 messages can be relayed messages, and the transmitting terminal can be a relay terminal. The Link 16 messages can be concatenated within the envelope LET message, or another lossless packaging algorithm such as lossless compression can be applied. The terminals can be JTRS terminals, the Link 16 messages can be 115 kbps messages, and the envelope LET message can be a 2 Mbps LET message.
