Breakout Gateway for Multi-Network Packet Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication devices lack efficient methods to simultaneously support both core network communications and local area network connectivity via a single bearer service, limiting their ability to seamlessly interact with multiple networks.
Innovation Solution
A network device with a receiving unit, sending unit, and evaluating unit that receives trigger signals to break out packets from a bearer service, distinguishing between packets from different sources and routing them appropriately to either a core network server or a separate local area network, utilizing a Breakout-Gateway (BOGW) function for packet routing and IP address management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single bearer service is used for both core network and local area network communications, then device complexity is reduced and ease of operation is improved, but the ability to simultaneously support multiple networks is limited
Solution Approach 1:
The patent segments packet traffic into two distinct types: packets from a first source (core network communications) and packets from a second source (local area network communications). The network device applies different routing rules to each packet type, enabling simultaneous support for both networks while using a single bearer service. This segmentation allows the system to maintain simplicity while achieving multi-network adaptability.
2Device complexity
If packets from different sources are routed through the same bearer service, then device complexity is reduced, but the ability to distinguish and route packets to different networks is impaired
Solution Approach 1:
The patent applies local quality by evaluating packets based on their source characteristics. The network device examines specific packet attributes (such as source address or other identifying features) to determine whether a packet originates from the first source (core network) or the second source (local area network). This packet-level differentiation enables appropriate routing decisions without requiring complex system architecture.
3Adaptability or versatility
If breakout functionality is added to enable simultaneous multi-network access, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a breakout gateway as an intermediary network device that performs the packet evaluation and routing functions. This intermediary handles the complexity of distinguishing between packet sources and applying appropriate routing rules, while the mobile device itself remains simple. The breakout gateway mediates between the single bearer service and the multiple network destinations, enabling adaptability without significantly increasing device complexity at the mobile end.
