Local Tunnel Base Station Data Traffic Offload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile telecommunication networks face radio resource insufficiency and increased loading on the core network due to growing data traffic, with no specific solution provided by 3GPP for peer-to-peer data traffic offload, leading to core network overload and reduced user satisfaction.
Innovation Solution
A method and system that create a local tunnel between base stations to route network packets directly on the front-end network, reducing the need for data to traverse the core network, utilizing existing 3GPP standards and infrastructure without requiring changes to user equipment or core network components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data traffic is routed through the core network according to traditional 3G network architecture, then network management and control is simplified, but core network loading increases and resource insufficiency occurs
Solution Approach 1:
The patent segments the network routing path by creating a local tunnel between base stations that bypasses the core network for peer-to-peer traffic. This segmentation allows local traffic to be handled independently at the access network level, reducing core network loading while maintaining simplified overall network management through selective routing based on traffic type.
Solution Approach 2:
The patent introduces a local tunnel as an intermediary routing path between base stations. This tunnel acts as a mediator that redirects peer-to-peer traffic locally without requiring core network involvement, thereby reducing core network loading while maintaining network control through the tunnel establishment mechanism.
2Quantity of substance
If local tunnel routing is implemented for peer-to-peer traffic, then core network loading is reduced, but network architecture complexity increases
Solution Approach 1:
The patent implements dynamic routing by establishing local tunnels only when needed for peer-to-peer traffic identification. The system dynamically creates and manages tunnels based on traffic type, switching between traditional core network routing and local tunnel routing as required, thereby reducing architecture complexity while maintaining core network loading reduction benefits.
Solution Approach 2:
The patent applies local quality by implementing tunnel routing specifically for peer-to-peer traffic at the local base station level, while maintaining traditional core network routing for other traffic types. This localized application of the tunnel mechanism reduces overall architecture complexity by limiting the complex routing logic to only where it is needed.
3Adaptability or versatility
If 3GPP standard routing is used for all traffic, then network compatibility is maintained, but peer-to-peer traffic offload capability is insufficient
Solution Approach 1:
The patent enhances universality by making the base station routing system multi-functional. It can handle both traditional core network routing for general traffic and local tunnel routing for peer-to-peer traffic within the same network infrastructure. This multi-functionality maintains 3GPP standard compatibility while adding peer-to-peer offload capability through the optional tunnel mechanism.
Solution Approach 2:
The patent applies preliminary action by pre-establishing local tunnels between base stations before peer-to-peer traffic needs to be routed. The tunnel setup is performed in advance, allowing immediate routing of peer-to-peer traffic through the local path without requiring real-time tunnel creation, thereby enhancing offload capability while maintaining standard compatibility.
