Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in providing efficient multiple unique identifiers for Wi-Fi access points, offloading and routing network traffic from cellular networks to trusted public/private Wi-Fi access points, and categorizing users based on unique identifiers without impacting user experience or data/voice plan speeds.
Innovation Solution
A method and system that utilize a routing device to provide and manage both public and private wireless networks with unique service set identifiers, establishing connections with user equipment, categorizing network traffic based on these identifiers, and routing it to corresponding gateways connected to the core network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If macro base stations are deployed to provide cellular network coverage, then coverage area is improved, but network capacity degrades quickly with increasing number of user equipment
Solution Approach 1:
The patent segments the network into multiple access types (trusted non-3GPP Wi-Fi access and untrusted non-3GPP Wi-Fi access) with separate routing paths. This allows the system to handle different user needs through different networks, preventing capacity degradation in the cellular network while maintaining broad coverage.
Solution Approach 2:
The patent introduces a routing device as an intermediary that manages traffic between user equipment and the core network. The routing device categorizes traffic based on destination address and routes it through appropriate gateways (TWAG for trusted access, PGW for untrusted access), enabling efficient load distribution and preventing capacity bottlenecks.
2Strength
If macro base stations are deployed to provide outdoor coverage, then signal strength is improved, but indoor coverage and signal strength deteriorate due to poor penetration
Solution Approach 1:
The patent provides different network access qualities for different locations. Trusted non-3GPP access (with TWAG) is deployed in indoor locations where strong cellular signal is unavailable, while untrusted non-3GPP access (with PGW) serves outdoor hotspot areas. This local differentiation ensures appropriate service quality matches the physical coverage conditions.
3Area of stationary object
If Wi-Fi access points are deployed to provide indoor coverage and offload traffic, then indoor coverage is improved, but difficulty arises in providing multiple unique identifiers and controlling bandwidth
Solution Approach 1:
The routing device performs multiple functions: it manages both trusted and untrusted non-3GPP access, provides multiple unique identifiers (TWAG and PGW), controls bandwidth for different access types, and routes traffic based on destination addresses. This multi-functionality consolidates what would otherwise require separate systems into a single device, reducing overall system complexity.
4Productivity
If traffic offloading to Wi-Fi access points is implemented, then network capacity is improved, but difficulty arises in routing service traffic without impacting user experience and data/voice plan speeds
Solution Approach 1:
The routing device dynamically routes traffic based on destination address categories. Different destination addresses are routed through different gateways (TWAG for trusted access, PGW for untrusted access) based on real-time network conditions and user subscription profiles. This dynamic routing ensures optimal path selection that maintains user experience quality while maximizing network capacity utilization.
