IEEE 802.15.4 NETWORK SYSTEM PROVIDING MOBILITY AND OPERATING METHOD THEREOF
First Claim
1. An IEEE 802.15.4 network system comprising:
- at least one stationary device allocated with an address for association with an IEEE 802.15 network and an ID indicating a preset device type to be associated with the IEEE 802.15.4 network;
a coordinator for allocating the address and the ID to the stationary device to be associated with the network, the coordinator having allocation address information and allocation ID information related, respectively, to the address and the ID allocated to the stationary device; and
a mobile device associated with the network through the coordinator, the mobile device receiving the allocation address information and the allocation ID information of the stationary device from the coordinator to control the stationary device.

Abstract
An IEEE 802.15.4 network system capable of directly controlling a stationary device without through a coordinator. The IEEE 802.15.4 network system includes: at least one stationary device allocated with an address and an ID indicating a preset device type to be associated with the IEEE 802.15.4 network; and a coordinator for allocating the address and the ID to the stationary device to be associated with the network. The coordinator has allocation address information and allocation ID information related, respectively, to the address and the ID allocated to the stationary device. A mobile device is associated with the network through the coordinator to receive the allocation address information and the allocation ID information of the stationary device from the coordinator to directly control the stationary device without through the coordinator.

9. A method of operating an IEEE 802.15.4 network by a mobile device, in which the network includes a coordinator, at least one stationary device and a mobile device, the method comprising:
-
transmitting an association request command to the coordinator; upon receiving an acknowledgment from the coordinator in response to the association request command, transmitting a data request command to the coordinator; upon receiving an acknowledgment from the coordinator in response to the data request command, associating with the network, and upon receiving allocation address information related with an address allocated to the stationary device for association with the network and an allocation ID information allocated to the stationary device and related with an ID indicating a preset device type, transmitting an acknowledgment to the coordinator in response to the allocation address information and the allocation ID information of the stationary device; and controlling the stationary device based on the allocation address information and the allocation ID information of the stationary device and receiving an acknowledgment from the stationary device in response to the mobile device controlling the stationary device. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of operating an IEEE 802.15.4 network by a mobile device, in which the network includes a coordinator, at least one stationary device and a mobile device, the method comprising:
-
transmitting an association request command to the coordinator; upon receiving an acknowledgment from the coordinator in response to the association request command, transmitting a first data request command to the coordinator, which requests allocation of an address for association with the IEEE 802.15.4 network; upon receiving an acknowledgment from the coordinator in response to the data request command, associating with the network; transmitting a second data request command to the coordinator to request allocation address information and allocation ID information from the coordinator, the allocation address information related with an address allocated to the stationary device for association with the network and the allocation ID information related with an ID indicating a preset device type allocated to the stationary device; receiving an acknowledgment from the coordinator in response to the second data request command, receiving the allocation address information and the allocation ID information of the stationary device from the coordinator, and transmitting an acknowledgment to the coordinator in response to the allocation address information and the allocation ID information of the stationary device; and controlling the stationary device based on the allocation address information and the allocation ID information of the stationary device and receiving an acknowledgment from the stationary device in response to the mobile device controlling the stationary device. - View Dependent Claims (16, 17, 18, 19, 20)
