Bluetooth private network and communication method thereof
First Claim
1. A Bluetooth private network for communicating with a public network, the Bluetooth private network comprising:
- a plurality of Bluetooth access points for functioning as base stations, each Bluetooth access point defining a Bluetooth piconet and interfacing between a signal transmitted from the public network and Bluetooth devices within each of Bluetooth piconets;
a gateway interfacing between the public network and the Bluetooth private network, sending a beacon signal to each of the Bluetooth devices to locate the Bluetooth devices, and communicating with a home agent of each of the Bluetooth devices to perform authentication of the each of the Bluetooth devices;
the Bluetooth device having a power measuring device therein that measures output power signals of a plurality of Bluetooth access points; and
a router for functioning as an interface between each of said Bluetooth access points.

Abstract
A Bluetooth private network comprises Bluetooth access points, each functioning as a base station in each of Bluetooth piconets, a gateway for functioning as an interface between a public network and the Bluetooth private network, sending a beacon signal to each of the Bluetooth devices in local Bluetooth networks to locate the Bluetooth device and a router for functioning as an interface between each of said Bluetooth access points. The Bluetooth device has a power measuring device therein that measures output power signals of a plurality of Bluetooth access points. When the Bluetooth device is moving from one piconet to another, the Bluetooth device compares the power signals received from two Bluetooth access points and links to the Bluetooth access point with the power signal that exceeds a predetermined level.

11. A Bluetooth private network, comprising:
-
first and second Bluetooth access points, the first Bluetooth access point defining a first Bluetooth piconet, the second Bluetooth access point defining a second Bluetooth piconet;
a gateway connected to the first and the second Bluetooth access points and sending a beacon signal to a Bluetooth device in the first Bluetooth piconet;
the Bluetooth device having a power measuring device therein that measures first and second power strength signals from the first and the second Bluetooth access point, respectively, wherein the Bluetooth device periodically compares the first and the second power strength signals with a predetermined power level; and
a router connected to the first and the second Bluetooth access points for functioning as an interface between each of said Bluetooth access points. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A communication method in a Bluetooth private network, the method comprising the steps of:
-
(a) transmitting from a gateway a beacon signal to a Bluetooth device for confirming a first piconet to which the Bluetooth device belongs;
(b) upon receiving the beacon signal, transmitting from the Bluetooth device a route update packet to the gateway to set a communication path with the gateway;
(c) transmitting from the Bluetooth device a home IP address and a home agent address to the gateway;
(d) upon receiving a registration request signal in the step (c), allocating from the gateway an address to the Bluetooth device to use the address in the piconet to which the Bluetooth device currently belongs;
(e) registering in the gateway with the address transmitted in the step (d); and
(f) when registered in the step (e), communicating from the Bluetooth device with other communication device in other network through the path set in the step (b). - View Dependent Claims (19, 20, 21)
