Mesh Nodes Alleviating Cellular Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular network congestion due to increasing machine type communication traffic and limited frequencies, leading to suboptimal connections for data transmission, particularly in cases where high data rates or low latency are required, necessitates effective congestion mitigation techniques.
Innovation Solution
A mesh network system where nodes determine the optimal access points to transmit data based on advertised access parameters, choosing either the lowest-cost path or paths with fewer restrictions to alleviate data restrictions, thereby mitigating congestion by routing data through access points with better connectivity.

1Productivity
If access class barring and extended access barring techniques are implemented to mitigate cellular network congestion, then network overload is reduced, but data transmission speed and latency performance deteriorate for affected devices
Solution Approach 1:
The invention segments the network access problem by identifying and isolating congested access points from non-congested ones. Nodes are divided into groups based on their access point status, and routing is segmented to direct traffic through appropriate paths - either directly through non-congested access points or indirectly through intermediate nodes connected to better access points, thereby maintaining high speed transmission while avoiding congested areas
Solution Approach 2:
The invention introduces intermediary nodes as mediators between nodes with congested access points and the cellular network. These intermediary nodes have better access to the cellular network and act as relay points, allowing data to be transmitted through alternative paths that avoid the congestion at the original access point, thus maintaining high data transmission speed while still contributing to overall network load management
2Reliability
If multiple access points are used with different data restrictions, then data transmission reliability improves, but network complexity increases
Solution Approach 1:
The invention implements self-service mechanisms where nodes automatically discover their own access point congestion status, autonomously determine their routing category (direct or indirect), and dynamically select optimal paths without manual configuration. The network nodes independently monitor access point conditions and adjust their routing decisions based on real-time information, eliminating the need for complex centralized management while maintaining high transmission reliability through multiple available paths
Solution Approach 2:
The invention makes the routing configuration dynamic rather than static. Nodes continuously monitor the status of their access points and automatically adapt their routing behavior based on current network conditions. When an access point becomes congested, nodes dynamically switch from direct routing to indirect routing through intermediaries, and when access points improve, they switch back. This dynamic adaptation maintains reliability without requiring complex fixed configurations

AI summary
A plurality of nodes in a first network mitigate data restrictions on access points which are an interface between the first network and a second network. The access points advertise their access parameters to the second network to the nodes. The nodes maintain a list of the advertised access parameters of each access point. The nodes determine whether to transmit data to the second network according to a first transmission mode or a second transmission mode based on the data to be transmitted and the list of access parameters maintained by that node. In the first transmission mode, the node determines to transmit the data to a first access point having a lowest cost with that node. In the second transmission mode, the node determines to transmit the data to a second access point having fewer access restrictions to the second network than the first access point.
