Patent Images
1. A ZigBee gateway comprising:
- an IP network communication unit supporting communications with an IP network;
a ZigBee network communication unit supporting communications with a ZigBee network; and
a message processing unit generating a forwarding entry containing a service request ID and a transaction sequence ID corresponding to a service request message, when the service request message is received from the IP network, and performing a forwarding operation between the service request message and a response message transmitted from the ZigBee network in response to the service request message, by referring to the forwarding entry.
