Container Unit, Message Switching Equipment, Routing Method, Routing Directory, and System for Monitoring Containers

摘要

The invention includes a message switching equipment for transmitting messages between container units placed in containers and a monitoring server. The message switching equipment comprises at least a container unit 201 , a gateway unit 202 providing communication links 203 , and a message handler 204 which is coupled to the monitoring server 205 . The message switching equipment is adapted to send a first message 206 from the container unit 201 via a cellular network 207 to the message handler 204 in response to an event relating to the container. In more detail, the first message 206 is sent through a cellular network radio 208 of the container unit 201 . The equipment is further adapted to receive through a short range radio 209 of the container unit 201 a second message 210 originated from one of the container units and transmit the second message 210 from the container unit 201 via the cellular network 207 to the message handler 204 . The equipment is further adapted to receive through a short range radio 211 of the gateway unit 202 a third message 212 and transmit the third message through the gateway unit 202 to the message handler 203.
