Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadband wireless networks face challenges in meeting user demands for bandwidth, particularly due to inter-cell interference, inefficient backhaul utilization, and latency issues caused by the distance between servers and user access points, which affects the quality of service, especially during emergencies or military operations.
Innovation Solution
Deployment of Optimization Servers within the LTE wireless network at PGW and eNB locations to reduce latency, minimize backhaul network usage, and improve bandwidth by relocating application functionality closer to mobile devices and processing data locally, thereby enhancing user experience and network efficiency.

Engineering Contradiction Analysis
1Device complexity
If servers are deployed externally at great distances from user access points, then network infrastructure complexity is reduced, but communication latency increases and quality of service deteriorates
Solution Approach 1:
The patent segments the network architecture by deploying optimization servers at multiple hierarchical levels (core network, regional, and base station levels) rather than having a single centralized external server. This segmentation reduces communication latency by placing servers closer to users while maintaining manageable infrastructure complexity through modular deployment.
Solution Approach 2:
The patent introduces a spatial dimension to server deployment by distributing optimization servers across multiple geographic locations and network levels. Instead of a single centralized location, servers are positioned at core network nodes, regional points, and base stations, creating a multi-dimensional server architecture that reduces latency without proportionally increasing complexity.
2Ease of manufacture
If backhaul facilities operate at moderate capacity (1 Gbps), then deployment cost is reduced, but bandwidth availability becomes insufficient for video applications and system capacity is limited
Solution Approach 1:
The patent merges multiple backhaul connections and optimizes their utilization through intelligent traffic management at optimization servers. By combining and efficiently routing traffic across multiple 1 Gbps backhaul facilities, the system achieves effective bandwidth aggregation that provides sufficient capacity for video applications without requiring each individual backhaul link to operate at higher, more expensive capacities.
Solution Approach 2:
The patent changes the operational parameters of backhaul facilities by implementing dynamic traffic prioritization, compression, and routing strategies at optimization servers. These parameter changes enable moderate-capacity backhaul links (1 Gbps) to deliver effective bandwidth sufficient for video applications through optimized data flow management rather than relying on raw link capacity.
3Device complexity
If LTE base stations are deployed with standard air interface capacity, then network deployment complexity is reduced, but inter-cell interference increases and system throughput is limited
Solution Approach 1:
The patent introduces optimization servers as intermediary components between LTE base stations and the core network. These intermediaries manage and coordinate communications between base stations, implementing interference mitigation strategies and resource optimization algorithms that increase system throughput without requiring complex modifications to the standard LTE air interface or base station hardware.

AI summary
An example system includes a server communicatively connected to a cellular base transceiver station having an RF coverage area and configured for RF communication with a first entity that is a transceiver device in the RF coverage area, wherein the server comprises a first publish-subscribe broker that is part of a publish-subscribe broker network that comprises one or more publish-subscribe brokers, wherein a second entity connected to any of the one or more publish-subscribe brokers in the publish-subscribe broker network accepts communications from the transceiver device if the second entity subscribes to data packets published by the transceiver device, and wherein the data packets published by the transceiver device are routed through the publish-subscribe broker to which the second entity is connected.
