Virtual Anchor Point for Fixed Wireless Offload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixed wireless access (FWA) networks face challenges with identifying user devices and managing increased traffic, leading to congestion, latency, and reduced performance due to the reliance on a central gateway.
Innovation Solution
A method that analyzes signal data from user devices to identify FWA devices and switches them to a virtual anchor point associated with a single cell site, bypassing the central gateway for optimized data transmission with low latency and high bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a central gateway is used to manage all FWA devices, then network control is simplified, but network congestion and latency increase
Solution Approach 1:
The patent segments the central gateway function by introducing virtual anchor points associated with individual cell sites. Each FWA device is served by a virtual anchor point linked to its serving cell site, distributing the gateway functionality across multiple locations rather than relying on a single centralized gateway. This segmentation reduces congestion and latency while maintaining simplified control through the network controller that manages the virtual anchor points.
2Device complexity
If a central gateway is used for FWA devices, then centralized management is achieved, but network performance and bandwidth are reduced
Solution Approach 1:
The patent divides the centralized gateway function into multiple virtual anchor points distributed across different cell sites. Each virtual anchor point handles traffic for devices in its associated cell site, enabling parallel processing of data transmissions and reducing the bottleneck effect of a single centralized gateway. This maintains centralized management through the network controller while significantly improving data transmission bandwidth and performance.
Solution Approach 2:
The patent introduces virtual anchor points as intermediary elements between FWA devices and the central network. These virtual anchor points act as local gateways that mediate traffic flow, reducing the load on the central gateway and enabling optimized data transmission paths. The virtual anchor points maintain the simplified management architecture while improving network performance through distributed intermediaries.
3Area of stationary object
If multiple cell sites are used to serve FWA devices, then coverage is improved, but device identification and traffic management become more complex
Solution Approach 1:
The patent introduces virtual anchor points as intermediary elements that simplify the relationship between multiple cell sites and FWA devices. Each virtual anchor point is associated with a specific cell site and handles device identification and traffic management for devices in that cell site. This intermediary structure maintains comprehensive coverage across multiple cell sites while simplifying management through standardized virtual anchor point interfaces controlled by the network controller.

AI summary
The present technology relates to a method and system for providing fixed wireless access (FWA) services to user devices in a cellular network. The system is configured to receive signal data from the user device operating within the coverage area of the cell site and analyze the signal data to identify characteristics that indicate the user device is a FWA device. Upon determining that the user device is a FWA device, the controller switches the user device to a virtual anchor point associated with the cell site, enabling the device to connect to the network using FWA services. The virtual anchor point is associated with the cell site and may be established through a virtual gateway.
