Title:
マルチゲートウェイ通信方法及びその無線ゲートウェイシステム
Document Type and Number:
Japanese Patent JP6739560
Kind Code:
B2
Abstract:
The disclosure is related to a multi-gateway communication method. The method is applied to a wireless gateway system that includes multiple nodes including a number of gateways. A root gateway is provided among the gateways. When a gateway receives an uplink data from a node, the uplink data is transmitted to a backend server if the gateway is the root gateway. The uplink data is transmitted to a parent gateway if the gateway is not the root gateway. On the other hand, when the gateway receives downlink data from a node, it is determined if a destination node is recorded in a downlink routing table of a descendant gateway if gateway is not connected with the destination node but with the descendant gateway. If the destination node is recorded in the downlink routing table, the data is transmitted to the descendant gateway; otherwise, the downlink data is discarded.
