Inter-Network SMS Routing Between Private and Public 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to provide seamless inter-network short message service (SMS) between private and public 5G networks, leading to message loss or delay when a wireless device is registered to one network but receives messages intended for another network.
Innovation Solution
The system employs a method where a first server on a public 5G network receives a message intended for a wireless device with a specific network identity, determines the associated network identity on a private 5G network, and sends a copy of the message to a second server on the private network for delivery to the wireless device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless device is registered to one network (public or private), then it can receive messages on that network, but it cannot receive messages intended for its other network identity
Solution Approach 1:
The patent introduces an SMS center as an intermediary component that mediates message routing between public and private networks. The SMS center receives messages destined for a wireless device, determines which network the device is currently registered to, and forwards the message through the appropriate network path. This intermediary resolves the contradiction by enabling reliable message delivery across network boundaries without requiring the device to be simultaneously registered to multiple networks.
Solution Approach 2:
The SMS center is designed with multi-functional capability to handle messages for wireless devices regardless of which network they are registered to. It can route messages through either the public network or private network based on the device's current registration status, making the message delivery system universal and adaptable to different network configurations.
2Reliability
If the system routes messages through multiple network paths to ensure delivery, then message reliability improves, but system complexity increases
Solution Approach 1:
By centralizing the routing intelligence in the SMS center rather than distributing it across multiple network elements, the patent reduces overall system complexity. The SMS center acts as a single point of control that manages the complexity of multi-path routing, simplifying the architecture compared to having each network element independently handle routing decisions.
Solution Approach 2:
The patent merges the routing functionality for both public and private networks into a single SMS center component. This consolidation combines what could be separate complex routing systems into one unified entity, reducing the total system complexity while maintaining the ability to route messages through multiple network paths for reliability.

AI summary
Systems, methods, and computer-readable media are provided for inter-network messaging among private and public 5G networks. For instance, a first server on a public 5G mobile network can receive a first message directed to a first wireless device associated with a first network identity. The first server can determine, based on the first network identity, that the first wireless device is associated with a second network identity, wherein the second network identity is used to identify the first wireless device on a private 5G mobile network. The first server can send a copy of the first message to a second server on the private 5G mobile network for transmission to the first wireless device through the private 5G mobile network based on the second network identity.
