Multi-transceiver Node Link Profile Management for Multicast Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-transceiver communication systems are inefficient in handling multicast and broadcast traffic, as they typically rely on dedicated signaling channels, which limits network scalability and reduces efficiency, and fail to adapt to changing network conditions and non-cooperative signals.
Innovation Solution
A multi-transceiver network node architecture that incorporates dynamic spectrum access, link maintenance, and packet management modules to dynamically assign frequencies, manage links, and route packets efficiently across multiple transceivers, using cognitive radio techniques to avoid interference and adapt to changing network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multicast traffic is sent using the dedicated signaling channel, then broadcast functionality is achieved, but network scalability is limited and efficiency is reduced
Solution Approach 1:
The patent enables data channels to perform multiple functions: they can carry unicast traffic, multicast traffic, and broadcast traffic. This eliminates the need to use the dedicated signaling channel for broadcast traffic, as data channels are now universal carriers that can handle all types of traffic efficiently, resolving the contradiction between achieving broadcast functionality and maintaining network efficiency
Solution Approach 2:
The patent segments the network resources by assigning different types of traffic (unicast, multicast, broadcast) to different channels based on current network conditions. Instead of forcing all broadcast traffic through the signaling channel, the system can segment traffic and route broadcast/multicast traffic through appropriate data channels when conditions permit, improving overall network efficiency while maintaining versatility
2Productivity
If nodes use the channel with highest SINR or next idle channel, then unicast transmission efficiency is improved, but multicast and broadcast traffic are not accommodated
Solution Approach 1:
The patent implements dynamic channel assignment where the system continuously monitors network conditions and adapts channel usage accordingly. For unicast traffic, nodes dynamically select channels with highest SINR. For multicast and broadcast traffic, the system dynamically determines whether to use dedicated signaling channels or share data channels based on current load and conditions, thereby maintaining high unicast efficiency while adding versatility for group traffic
Solution Approach 2:
The patent changes the parameters of channel assignment by introducing new variables for multicast and broadcast traffic handling. Instead of a fixed rule for channel selection, the system adjusts channel assignment parameters based on traffic type, network load, and signal conditions, allowing efficient unicast transmission while accommodating multicast and broadcast requirements
3Reliability
If the dedicated signaling channel is used for control packets, then control functionality is ensured, but network scalability is limited
Solution Approach 1:
The patent makes data channels universal by enabling them to carry control packets, multicast traffic, and broadcast traffic in addition to unicast data. This eliminates the bottleneck of the dedicated signaling channel and allows the network to scale more effectively, as the capacity for control and group traffic is no longer limited by a single channel's bandwidth

AI summary
An apparatus includes a network node configured to communicate with other network nodes via a communication network. The network node includes a plurality of transceivers and a controller. The controller includes a packet management module that identifies a link profile solution set that includes a set of link profiles corresponding to communication links for multicasting the message packet. The link profile solution set maximizes coverage of network target nodes of the multicast message packet. The packet management module places a first message clone of the message packet in a transceiver queue for transmission to one or more of the network target nodes, updates the link profile solution set when the first message clone reaches the end of the transceiver queue, and initiates transmission of the first message clone or drop the first message clone according to the updated link profile solution set.
