Codebook-Based Message Compression for Bandwidth-Limited Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bandwidth limitations in telecommunication networks, particularly for non-terrestrial base stations, restrict the amount of messaging that can be transmitted, as conventional solutions are inadequate for managing mobile originating messages in such environments.
Innovation Solution
A method and system that utilize a dictionary or translator at the user equipment to encode messages using a codebook, reducing the message size before transmission through bandwidth-restricted base stations, and decoding them at a resource-rich location for communication to the intended user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional messaging transmission is used in bandwidth-limited networks, then message delivery is straightforward, but bandwidth consumption is excessive and strain on base stations increases
Solution Approach 1:
The patent applies preliminary action by encoding messages at the user equipment before transmission. The messaging application encodes the original message using a codebook to generate a code index, which is then transmitted instead of the full message. This pre-encoding reduces the data size before it enters the network, thereby reducing bandwidth consumption and strain on base stations while maintaining a relatively simple system architecture.
2Quantity of substance
If message compression is implemented at user equipment, then bandwidth usage is reduced, but encoding and decoding complexity at user equipment increases
Solution Approach 1:
The patent applies copying by using a codebook that maps original messages to compact code indices. Instead of transmitting the full message content, the system transmits only the code index (a copy reference) that points to the original message in the codebook. This dramatically reduces message size while keeping the encoding logic simple - essentially replacing large data with small references.
Solution Approach 2:
The patent applies parameter changes by transforming the message representation from full text content to compact code indices. The messaging application changes the parameter representation of messages, encoding them as numerical indices rather than textual content. This parameter transformation reduces the amount of data transmitted while maintaining the ability to reconstruct the original message at the receiving end.
3Productivity
If codebook-based encoding is used for message compression, then transmission efficiency is improved, but compatibility with existing networks requires additional protocols
Solution Approach 1:
The patent applies intermediary by using the base station as a mediator in the communication process. The base station receives code indices from user equipment, retrieves the corresponding original messages from its local codebook, and then transmits the full messages to other users. This intermediary approach allows codebook-based compression to work with existing network infrastructure without requiring end-to-end protocol changes, as the base station handles the codebook management and message reconstruction.

AI summary
Systems and methods are provided to improve transmittance of messages across bandwidth limited networks. Modern telecommunication networks utilize radio frequency (RF) signaling to transmit and receive signals between a base station and a user equipment. Particularly for some base stations, bandwidth availability may be limited based on its location with respect to the mobile originating devices or that the base-station may be non-terrestrial. Such limited bandwidth restricts the amount of messaging that may be transmitted. By utilizing a series of coding and decoding of messages, these messages may use less bandwidth and reduce strain on those limited base stations.
