ZigBee network device for separately determining network parameter and assigning addresses, and address assignment method thereof
First Claim
1. A ZigBee network device comprising:
- a communication unit which connects the ZigBee network device to other devices and which communicates with the other devices;
a parameter determination section which determines at least one network parameter;
a calculation section which calculates addresses for child devices of the ZigBee network device based on a determined network parameter, wherein each of the child devices is connected to the ZigBee network device via the communication unit; and
a controller which assigns the addresses to the child devices of the ZigBee network device;
wherein the at least one determined network parameter is at least one of Cm, which indicates a maximum number of child devices of the ZigBee network device, and Rm, which indicates a maximum number of the child devices of the ZigBee network device which have routing capabilities, andwherein the Cm and Rm are individually and discretely calculated by each ZigBee network device in a ZigBee network environment.

Abstract
A ZigBee network device assigns addresses to its child devices. The ZigBee network device includes a communication section that connects the ZigBee network device to other devices and which communicates with the other devices; a parameter determination section that determines at least one network parameter; a calculation section that calculates addresses for child devices of the ZigBee network device based on a determined network parameter, where each of the child devices is connected to the ZigBee network device via the communication section; and a controller that assigns addresses to the child devices of the ZigBee network device. At least one determined network parameter is at least one of Cm, which indicates a maximum number of the child devices of the ZigBee network device, and Rm, which indicates a maximum number of the child devices of the ZigBee network device which have routing capabilities.

5. An address assignment method of a ZigBee network device under a ZigBee network environment of a cluster tree structure, the method comprising:
-
determining, by a processor of the ZigBee network device, at least one network parameter; calculating addresses for child devices of the ZigBee network device; and assigning the addresses to the child devices of the ZigBee network device based on a connection order of the children; wherein the at least one network parameter is at least one of Cm, which indicates a maximum number of the child devices of the ZigBee network device, and Rm, which indicates a maximum number of the child devices of the ZigBee network device with routing capabilities, and wherein the Cm and Rm are individually, and discretely calculated by each ZigBee network device in a ZigBee network environment. - View Dependent Claims (6, 7, 8)
