Local Breakout Gateway for Low Latency Traffic Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless communication systems face challenges in providing low latency and high bandwidth services due to increasing resource constraints, necessitating direct access to local resources such as local servers and networks instead of remote core networks.
Innovation Solution
Implementing a local breakout architecture with a network node that includes a traffic aggregation block and quality of service block, which filters and aggregates traffic based on predefined filters and policies, enabling local traffic to be routed with lower latency than remote traffic, and allowing quality of service to be triggered locally for specific applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traffic is routed through remote core networks, then network coverage and connectivity are improved, but latency increases and throughput decreases
Solution Approach 1:
The patent segments traffic into local traffic and remote traffic, routing them through different paths. Local traffic is directed to local data networks for low-latency access, while remote traffic goes through the core network. This segmentation resolves the contradiction by providing optimized paths for different traffic types.
Solution Approach 2:
The gateway device acts as an intermediary between the wireless communication device, local data networks, and remote core networks. It performs traffic detection, filtering, and routing decisions, enabling local breakout traffic to bypass the remote core network while maintaining connectivity for other traffic.
2Loss of time
If all traffic is routed through local networks, then latency is reduced and throughput is improved, but network compatibility and coverage are compromised
Solution Approach 1:
The system dynamically routes traffic based on real-time conditions and traffic type. The gateway device continuously monitors traffic characteristics and adjusts routing decisions, enabling the system to adapt between local and remote network paths as needed, thus maintaining both low latency and network compatibility.
Solution Approach 2:
The gateway device performs multiple functions including traffic detection, filtering, routing, and protocol translation. This multi-functionality enables it to handle both local breakout traffic and traditional remote traffic, ensuring network compatibility while providing low-latency paths when available.
3Productivity
If traffic filtering and aggregation is implemented, then traffic management and quality of service are improved, but device complexity increases
Solution Approach 1:
The gateway device performs preliminary traffic filtering and classification before routing decisions. By pre-processing traffic and establishing filter rules in advance, the system simplifies real-time routing decisions and reduces the computational complexity during active traffic management.
4Speed
If local breakout architecture is implemented, then low latency and high bandwidth are achieved, but network architecture complexity increases
Solution Approach 1:
The gateway device serves as an intermediary that manages the complexity of the local breakout architecture. It handles traffic detection, filtering, and routing between local and remote networks, thereby simplifying the overall system while enabling low-latency local access and maintaining compatibility with existing network infrastructures.

AI summary
Aspects of this disclosure relate to local breakout. A network node can receive remote downlink traffic from a remote network, receive local downlink traffic from a local resource, aggregate at least the remote downlink traffic with the local downlink traffic based on one or more filters stored in memory of the network node, and route the aggregated downlink traffic to a wireless communication device. The remote downlink traffic can be associated with a first application of the wireless communication device, and the local downlink traffic can be associated with a second application of the wireless communication device. The network node can be a local gateway in certain embodiments. The network node can steer uplink traffic steering by filtering uplink traffic associated with the wireless communication device into local uplink traffic and remote uplink traffic based on at least one filter for filtering traffic stored in the memory.
