Multi-PDN Cellular Gateway for Simultaneous IP Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular network gateways are limited in handling multiple to multiple channel transfers between cellular network devices and physically wired network devices, such as network firewall devices, which restricts the ability to process multiple streams of IP traffic effectively.
Innovation Solution
The implementation of a multi-PDN cellular gateway system that enables multiple IP traffic connections between private networks and public data networks by using multiple modems and cellular gateways to establish and manage multiple data channels, allowing for the transfer of different types of data streams over distinct channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single cellular modem is used to connect one channel from the wired network device to the cellular network, then the device structure remains simple, but the system cannot handle multiple to multiple channel transfers between cellular network devices and physically wired network devices
Solution Approach 1:
The system segments the channel transfer function by implementing multiple independent modems (first cellular modem, second cellular modem) within the network gateway device. Each modem handles specific data channels independently, enabling the system to manage multiple simultaneous channel transfers between cellular and wired networks without requiring a single complex modem to handle all transfers
2Productivity
If multiple modems are implemented to enable multiple to multiple channel transfers, then the system can process multiple streams of IP traffic effectively, but the device complexity increases
Solution Approach 1:
The network gateway device is designed with multi-functionality by incorporating multiple cellular modems that can simultaneously handle different data channels. The gateway device universally manages IP traffic processing, channel establishment, and data transmission across multiple cellular and wired network interfaces, enabling it to process multiple streams of IP traffic effectively while providing a unified management architecture
