System and method for managing the association of device with a piconet
First Claim
1. An apparatus that associates devices with a piconet, the apparatus comprising:
- an association device list updater, which updates an association device list of a first device by referring to an association device list, on which the devices associated with the piconet are registered and association elapsed periods of the devices are recorded;
an association elapsed period extractor, which, when the first device requests communication with a second device registered on the updated association device list, extracts an association elapsed period of the second device from the updated association device list; and
an inter-device communicator, which, if the extracted association elapsed period is shorter than an association timeout period, performs the communication between the first and second devices.

Abstract
A system that manages associations of devices with a piconet is provided. The system includes a piconet-device association coordinator, which receives, from a first device, a second association request command that indicates a proper allocation of a device ID to the first device, sets an association elapsed period of the first device to an initial value, and registers the first device and records the association elapsed period to an association device list so that the first device corresponds to the association elapsed period; and a piconet-device associator, which updates an association device list of the first device by referring to the association device list, extracts an association elapsed period of a second device registered on the updated association device list from the updated association device list when the first device requests communication with the second device, and performs the communication between the first and second devices if the extracted association elapsed period is shorter than an association timeout period.

8. An apparatus that coordinates associations of devices with a piconet, the apparatus comprising:
-
a second association request command receiver, which receives, from a first device, a second association request command that indicates that a device ID has been properly allocated to the first device;
an initial association elapsed period setter, which, when the second association request command receiver receives the second association request command, sets an association elapsed period of the first device to an initial value; and
an association device list maker which registers the first device and records the set association elapsed period on an association device list so that the set association elapsed period corresponds to the first device. - View Dependent Claims (9, 10, 11, 12)

13. A system that manages associations of devices with a piconet, comprising:
-
a piconet-device association coordinator, which receives, from a first device, a second association request command that indicates a proper allocation of a device ID to the first device, sets an association elapsed period of the first device to an initial value, and registers the first device and records the association elapsed period to an association device list so that the first device corresponds to the association elapsed period; and
a piconet-device associator, which updates an association device list of the first device by referring to the association device list, extracts an association elapsed period of a second device registered on the updated association device list from the updated association device list when the first device requests communication with the second device, and performs the communication between the first and second devices if the extracted association elapsed period is shorter than an association timeout period.

14. A method of associating devices with a piconet, the method comprising:
-
updating an association device list of a first device by referring to an association device list, on which the devices associated with the piconet are registered and association elapsed periods of the devices are recorded;
if the first device requests communication with a second device registered on the updated association device list, extracting an association elapsed period of the second device from the updated association device list; and
if the extracted association elapsed period is shorter than an association timeout period, performing the communication between the first and second devices. - View Dependent Claims (15, 16, 17, 18, 19, 20, 27)

21. A method of coordinating associations of devices with a piconet, the method comprising:
-
receiving, from a first device, a second association request command that indicates that a device ID has been properly allocated to the first device;
if the second association request command is received, setting an association elapsed period of the first device to an initial value; and
registering the first device and recording the set association elapsed period to an association device list so that the set association elapsed period corresponds to the first device. - View Dependent Claims (22, 23, 24, 25, 28)

26. A method of managing associations of devices with a piconet, comprising:
-
receiving, from a first device, a second association request command that indicates that a device ID has been properly allocated to the first device, setting an association elapsed period of the first device, and registering the first device and recording the set association elapsed period to an association device list so that the first device corresponds to the set association elapsed period; and
updating the association device list of the first device by referring to the association device list, extracting an association elapsed period of a second device registered on the updated association device list from the updated association device list if the first device requests communication with the second device, and performing the communication between the first and second devices if the extracted association elapsed period is shorter than an association timeout period. - View Dependent Claims (29)

- 30. A beacon frame comprising a field in which devices associated with a piconet are registered and association elapsed periods of the devices are recorded.
- 31. A device information command frame comprising a field that comprises a value that indicates that a predetermined device does not associate with a piconet, wherein the predetermined device being registered on an association device list on which devices associated with the piconet are registered and association elapsed periods of the devices are recorded.
- 32. A peer information command frame comprising a field that comprises a value that informs a piconet coordinator that communication between devices associated with a piconet has ended, wherein the piconet coordinator manages the piconet.
