Satellite Proxy Network for Cellular Messaging Bridging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current satellite and cellular networks face challenges in seamlessly routing message replies from cellular networks to satellite-based senders, leading to a gap in messaging services between these two platforms.
Innovation Solution
A satellite proxy network is introduced to facilitate messaging services between cellular and satellite networks by registering as a Visitor Location Register Mobile Switching Center (VMSC) with the communication device's Home Location Register (HLR) when the device transitions to satellite mode, enabling the routing of SMS messages between the two networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device in satellite mode transmits messages to a cellular-based recipient, then the message can be sent successfully, but the device cannot receive message replies sent from the cellular network
Solution Approach 1:
The patent introduces a satellite proxy network that acts as an intermediary between satellite and cellular networks. The proxy receives messages from cellular devices and forwards them to satellite devices, and conversely receives messages from satellite devices and forwards them to cellular devices. This mediator enables bidirectional communication by bridging the two incompatible network types, allowing the satellite device to send messages to cellular recipients and receive replies through the proxy without requiring direct cellular network access.
2Adaptability or versatility
If a satellite proxy network registers as a VMSC with the HLR to enable message routing, then seamless messaging between networks is achieved, but system complexity increases
Solution Approach 1:
The satellite proxy network is designed to perform multiple functions within a single system: it acts as a VMSC for satellite device registration, functions as an SMSC for message storage and forwarding, and serves as a gateway between satellite and cellular networks. By consolidating these diverse functions into one multi-functional proxy system, the patent enables cross-network messaging capability while managing overall system complexity through functional integration rather than proliferation of separate components.
