Private Cellular Router Traffic Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large cellular wireless service providers face challenges in meeting increased demand for wireless connectivity, especially in areas where providing services is economically infeasible, leading to gaps in coverage and service quality for both home and roaming devices.
Innovation Solution
A private cellular network system with specially configured routers that manage traffic by determining the source of data packets and routing them internally or externally based on validity, prioritizing processing for home or guest endpoints, and providing connectivity to confined geographical areas where standard networks do not meet service thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If large cellular wireless service providers expand coverage to meet increased demand, then service availability improves, but infrastructure cost and operational complexity increase significantly
Solution Approach 1:
The patent segments the cellular network into hierarchical levels: core networks, access networks, and edge networks. Private cellular networks are deployed at the edge level to handle local traffic demands, while core networks maintain centralized control. This segmentation allows service expansion without proportionally increasing overall infrastructure complexity.
Solution Approach 2:
The patent introduces a new dimensional approach by deploying private cellular networks in confined geographical areas (edge networks) rather than relying solely on traditional wide-area core network expansion. This adds a spatial dimension to network deployment, allowing localized service improvement without proportional increases in overall infrastructure complexity.
2Productivity
If private cellular networks deploy additional routers and monitoring systems to manage traffic from home and roaming devices, then traffic management capability improves, but device complexity increases
Solution Approach 1:
The router is designed with multi-functionality, serving as a proxy router that simultaneously performs traffic monitoring, traffic steering, authentication, and routing functions. This consolidates multiple specialized devices into a single universal router, improving traffic management capability while avoiding proportional increases in device complexity.
Solution Approach 2:
The patent merges the functions of traffic monitoring and traffic steering into a single integrated router system. The proxy router combines authentication, monitoring, and routing capabilities in one device, eliminating the need for separate monitoring systems and reducing overall router complexity while enhancing traffic management productivity.
3Reliability
If the system implements comprehensive traffic analysis and source validation for all data packets, then network security and service quality improve, but processing time and operational complexity increase
Solution Approach 1:
The proxy router performs preliminary authentication and validation of data packet sources before routing decisions. By validating sources in advance and maintaining authentication states, the system ensures network security while reducing per-packet processing time, as subsequent packets from authenticated sources require minimal re-validation.
4Adaptability or versatility
If the private cellular network provides services to both home endpoints and guest endpoints from multiple home cellular networks, then network versatility and user experience improve, but system complexity and management overhead increase
Solution Approach 1:
The proxy router acts as an intermediary between guest endpoints from multiple home cellular networks and the private cellular network core. It mediates authentication, traffic steering, and routing decisions, allowing the network to serve diverse endpoints while maintaining centralized control and avoiding proportional increases in system complexity.
Data Source
AI summary
A router of a private cellular network is configured to receive data packets from a plurality of endpoints; analyze the data packets to determine a corresponding source of each data packet; determine whether each corresponding source is a valid source; drop a data packet for which the corresponding source is invalid; for a data packet received from a valid source, determine whether to process the data packet internally or forward the data packet for external processing and route the data packet to a corresponding destination, the corresponding destination being one of a local enterprise network or a corresponding home cellular network of the valid source from which the data packet is received, wherein the private cellular network is configured to service a confined physical location in which home cellular networks of data packets received from valid sources do not provide cellular connectivity that meets a threshold level of cellular service.
