Abstract
A system and method for routing LoRaWAN backend traffic between peer visited and home Network Server nodes to achieve global roaming in a scalable manner. A LoRaWAN Routing and Control System (LRCS) node is deployed between a visited Network Server and a home Network Server and is configured to proxy signaling and payload data messages therebetween. LRCS node can provide policy control, billing and rating based on roaming agreements between peer LoRaWAN roaming networks. LRCS node protects the overall network by discarding blacklisted and malicious traffic. LRCS node can enhance the message flow logic by adding routing information in the messages such that destination networks can identify that message is routed through a trustable source.
