Wireless Packet Routing via Native Protocol Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hybrid wireless communication devices, such as those using Generic Access Network (GAN) or Unlicensed Mobile Access (UMA), experience significant bandwidth reduction and increased costs due to excessive overhead when communicating over wireless local area networks, as they require traffic to pass through a Generic Access Network Controller or UMA network controller, mimicking a traditional base station controller and routing through the core mobile network.
Innovation Solution
A system and method that enables wireless communication devices to communicate directly with device access nodes using native network layers specific to wireless local area networks or core mobile networks, bypassing the core mobile network for external links, allowing packet transmission and reception through an application layer above the native network layers, thereby reducing overhead and maintaining bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traffic is routed through a Generic Access Network Controller (GANC) to maintain compatibility with traditional core mobile networks, then network compatibility and seamless communication are improved, but bandwidth efficiency deteriorates due to excessive overhead
Solution Approach 1:
The patent extracts the GANC controller from the communication path between WLAN access points and the core network. By allowing WLAN access points to communicate directly with the core network using native WLAN protocols, the unnecessary intermediary controller is removed, eliminating the overhead it generates while maintaining network compatibility through direct routing.
Solution Approach 2:
The patent introduces a new intermediary entity called a WLAN access controller that sits between WLAN access points and the core network. This controller provides protocol translation and coordination functions, enabling direct WLAN-to-core network communication while maintaining compatibility requirements, thus reducing overhead compared to routing through a traditional GANC.
2Reliability
If data is forced back through the carrier network via GANC, then network control and security are improved, but subscriber costs increase due to unnecessary network traversal
Solution Approach 1:
The patent removes the requirement for data to traverse back through the carrier network via GANC. By enabling direct routing between WLAN access points and the core network, data takes an optimized path that eliminates unnecessary network traversal, maintaining security through direct authenticated connections while reducing subscriber costs.
3Quantity of substance
If native network layers specific to WLAN are used for direct communication, then bandwidth efficiency and cost are improved, but compatibility with traditional core mobile network infrastructure may deteriorate
Solution Approach 1:
The patent introduces a WLAN access controller as an intermediary that handles protocol translation between native WLAN network layers and traditional core mobile network protocols. This allows devices to use efficient native WLAN protocols for direct communication while the intermediary ensures compatibility with existing core network infrastructure, thus resolving the contradiction between efficiency and compatibility.
Solution Approach 2:
The patent segments the communication architecture into distinct functional layers: WLAN access points using native protocols for efficient data transmission, WLAN access controllers for protocol translation and coordination, and the core network for centralized management. This segmentation allows each component to operate optimally in its own domain while maintaining overall system compatibility.
