LTE Optimization Servers for Real-Time Service Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network architectures face challenges in delivering real-time services due to high connection and transmission loads at the server node, backhaul interface utilization, and inter-cell interference, which limits bandwidth and user experience, especially in supporting large numbers of users accessing video and audio content simultaneously.
Innovation Solution
Implementing a distributed Publish/Subscribe Broker communications architecture across Optimization Servers integrated into the LTE Wireless Network, which reduces connection loads at the server node, optimizes backhaul utilization, and minimizes inter-cell interference through Agile Beam Forming and strategic server deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional wireless network architecture is used to deliver real-time services to multiple users, then the service can be provided, but the server node experiences high connection and transmission loads
Solution Approach 1:
The patent segments the service delivery architecture by introducing intermediate optimization servers that distribute the connection and transmission loads. Instead of a single server node handling all user connections, the system divides functionality across multiple distributed servers, with each handling a subset of users and services, thereby reducing the load on any single node while maintaining overall service delivery capability.
2Productivity
If high data rates are provided to multiple users simultaneously, then user demand for video and audio services is met, but backhaul interface utilization becomes excessive
Solution Approach 1:
The patent merges multiple user data streams at the optimization server level before backhaul transmission. By combining traffic from multiple users that is bound for the same external destination, the system reduces redundant transmissions over the backhaul interface, thereby decreasing overall backhaul bandwidth consumption while still delivering high data rates to individual users through efficient traffic aggregation.
3Area of stationary object
If servers are deployed at great distances from the user access point, then service coverage area is expanded, but packet transit delays increase
Solution Approach 1:
The patent introduces a spatial dimension optimization by deploying optimization servers at strategic intermediate locations between remote servers and user access points. This creates a multi-layered architecture where traffic can be routed through geographically optimized paths, reducing packet transit delays for time-sensitive services while maintaining expanded service coverage area through the distributed server network.
4Speed
If LTE networks are used to provide high data rates, then user data rates reach up to 10 Mbps or higher, but inter-cell interference reduces system capacity
Solution Approach 1:
The patent introduces optimization servers as intermediary nodes that mediate between multiple LTE cells and the core network. These intermediary servers aggregate traffic from multiple cells and coordinate transmissions, thereby reducing inter-cell interference through centralized resource management and scheduling, which allows the system to maintain high user data rates while improving overall system capacity.
