Publish-Subscribe Broker for LTE Real-Time Service Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network architectures face challenges in delivering real-time services to a large number of users due to high connection and transmission loads at the server node, backhaul interface utilization, and the inability to efficiently manage inter-cell interference, leading to suboptimal user experience and capacity issues in LTE networks.
Innovation Solution
Implementing a distributed Publish/Subscribe (P/S) Broker communications architecture across Optimization Servers integrated into the LTE Wireless Network, which reduces the number of connections required at the server node, optimizes packet transmission rates, and minimizes backhaul utilization by replicating packets as needed within the P/S Broker network, rather than relying on traditional server replication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional server-based architecture is used to deliver real-time services to multiple users, then service delivery is achieved, but connection and transmission loads at the server node become excessively high
Solution Approach 1:
The patent segments the centralized server architecture into a distributed Publish/Subscribe Broker network where multiple broker nodes are distributed across the LTE network infrastructure. This segmentation divides the connection and transmission loads from a single server across multiple network elements, reducing the burden on any single node while maintaining service delivery capability.
Solution Approach 2:
The Publish/Subscribe Broker acts as an intermediary layer between service providers and users. Instead of direct server-to-user connections that create high loads, the Broker mediates by receiving publications once and distributing them to multiple subscribers, thereby reducing connection and transmission loads on the core network infrastructure.
2Device complexity
If traditional server replication is used to reduce connection loads, then processing capacity is improved, but backhaul interface utilization increases
Solution Approach 1:
The patent merges multiple subscriber connections into a single publication stream at the Broker. Instead of replicating service instances across multiple servers (which increases backhaul usage), the Broker combines multiple subscription requests and delivers a single copy of the published data to all subscribers, thereby reducing backhaul interface utilization while maintaining processing capacity.
3Adaptability or versatility
If external servers are deployed to provide services, then service variety is improved, but packet transit delays increase
Solution Approach 1:
The patent moves the service delivery architecture from a traditional external server dimension to a distributed network dimension by integrating Publish/Subscribe Brokers within the LTE network infrastructure. This dimensional shift allows services to be delivered through local network elements rather than remote external servers, reducing packet transit delays while maintaining service variety through the Broker's ability to handle multiple service types.
