Hub Breakout Roaming System for Reducing Data Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current roaming services in wireless communications systems face issues such as long data delays and interoperability problems in home routed roaming, and limitations in accessing private networks in local breakout roaming.
Innovation Solution
The hub breakout roaming approach, which uses a hub breakout system to assign IP addresses and route data packets for mobile devices, simplifying connections between home and visited networks, and enabling access to both internet and private networks through a hub network independent of the home and visited networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If home routed roaming is used, then roaming services are provided, but long data delays and interoperability issues occur
Solution Approach 1:
The patent introduces a local breakout system as an intermediary entity that receives data packets from the home network and forwards them through the visited network to the mobile device. This mediator eliminates the need for packets to travel back to the home network for routing decisions, thereby reducing data delay while maintaining roaming service reliability.
2Speed
If local breakout roaming is used, then faster connection is achieved, but access to private networks is limited
Solution Approach 1:
The local breakout system is designed with multi-functionality to handle both public internet traffic and private network traffic. It maintains connectivity to the home network's private networks while providing local breakout capabilities, enabling it to serve multiple purposes: fast internet access and secure private network communication simultaneously.
3Productivity
If hub breakout roaming is implemented, then data access delays are reduced and private network access is enabled, but system complexity increases
Solution Approach 1:
The patent segments the roaming system into distinct functional components: the home network, the visited network, and the local breakout system. Each component has specific responsibilities, with the local breakout system handling packet forwarding and routing decisions locally. This segmentation distributes complexity across multiple entities rather than concentrating it in one place, making the overall system more manageable despite the added functionality.
Data Source
AI summary
According to at least one example embodiment, hub breakout roaming enables providing data access to a user network device, subscribed with a home network and roaming into a visited network, by a hub breakout system through the visited network. Upon receiving a request for data access from the visited network, the hub breakout system assigns an IP address to the user network device. The hub breakout system then routes data packets, associated with the data access requested by the user network device, to and from at least one corresponding data source, using the assigned IP address. The data source includes the Internet, a private network associated with home network, or any other service provider entity.
