Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face latency issues due to changing radio environments, especially in wireless communication, and existing solutions like prioritizing channels or using multiple channels are costly or inefficient.
Innovation Solution
A method and apparatus that transmit and receive data packets over multiple wireless communication channels with different frequency bands, using indexed clones to ensure only the first packet is delivered, reducing latency by eliminating duplicates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple parallel communication channels are arranged between communicating entities, then latency is reduced, but network resource reservation cost increases
Solution Approach 1:
The communication channel is segmented into multiple parallel channels at the transmitting end, where data packets are split and sent through different channels. This allows latency reduction through parallel transmission without requiring the receiving end to maintain multiple permanent channels, thus reducing network resource reservation costs.
Solution Approach 2:
The patent introduces a new dimension of packet identification by adding index fields to data packets. This allows the system to track and reassemble packets from different channels without requiring permanent channel reservations, enabling flexible parallel transmission while conserving network resources.
2Loss of time
If communication channels are prioritized for critical applications, then latency is reduced, but latency spikes still occur due to changing radio environment
Solution Approach 1:
Data is segmented into multiple packets that are transmitted through different communication channels simultaneously. This segmentation diversifies the transmission paths, reducing the impact of radio environment changes on any single packet and ensuring more consistent latency performance.
Solution Approach 2:
The patent changes the transmission parameter by using multiple parallel channels with different characteristics instead of prioritizing a single channel. This allows the system to adapt to changing radio environments by having alternative paths available, improving latency consistency.
3Reliability
If data packets are transmitted over different radio interfaces at different frequency bands, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The transmitting end is designed with multi-functionality to handle multiple radio interfaces and frequency bands. This universal design allows the same device to transmit packets across different channels without requiring separate specialized hardware for each frequency band, managing complexity while maintaining reliability.
Solution Approach 2:
The patent introduces an intermediary indexing mechanism that mediates between multiple radio interfaces and the data packets. This intermediary system manages the complexity of multi-interface transmission by providing a unified method for tracking and reassembling packets from different frequency bands.

AI summary
The invention relates to a solution for managing a latency in communication between a transmitting end and a receiving end by arranging two communication channels over which two corresponding data packets are delivered and at the receiving end the first arrived data packet is accepted for further delivery. An apparatus, a method and a computer program are provided both at the transmitting and at the receiving end.
