1. A method of exchanging messages at a coordinator in a wireless network, the method comprising:
- receiving a change request message for requesting a change of a superframe duration length among configuration parameters of the wireless network from a device associated with the wireless network;
transmitting a response message to the device in response to the request message, wherein the response message comprises a command ID field comprising a unique number that identifies the response message, a length field indicating a length of the response message, and a reason code field comprising a reason code; and
transmitting a plurality of beacons to the device when the reason code field comprises the reason code of “
SUCCESS”
, wherein each of the plurality of beacons comprises a parameter change information element (IE) including a changed superframe duration length and a change beacon number field comprising a beacon number of a superframe when the change of the superframe duration takes effect,wherein the superframe duration length comprises the length of a superframe for channel resources allocated from the coordinator to another device, andwherein the parameter change IE comprises an IE index field comprising a unique number that identifies the parameter change IE, a change type field indicating a type of the parameter to be changed, and a network parameter field comprising information about a changed value of the parameter.

9. A coordinator of a wireless network comprising:
-
a transmitting module; a receiving module configured to receive a change request message for requesting a change of a superframe duration length among configuration parameters of the wireless network from a device of the wireless network; and a control module configured to generate a response message in response to the request message and to transmit the response message to the device via the transmitting module, wherein the response message comprises a command ID field comprising a unique number that identifies the response message, a length field indicating a length of the response message, and a reason code field comprising a reason code, wherein the control module is further configured to transmit a plurality of beacons to the device when the reason code field comprises the reason code of “
SUCCESS”
, wherein each of the plurality of beacons comprises a parameter change information element (IE) including a changed superframe duration length and a change beacon number field comprising a beacon number of a superframe when the change of the superframe duration takes effect,wherein the superframe duration length comprises the length of a superframe for channel resources allocated from the coordinator to another device, and wherein the parameter change IE comprises a IE index field comprising a unique number that identifies the parameter change IE, a change type field indicating a type of the parameter to be changed, and a network parameter field comprising information about a changed value of the parameter. - View Dependent Claims (10)
