Embodiment Construction

[0035] image 3 An example is shown in which the master of any one piconet operates as a slave of another piconet in a decentralized network, while Figure 4 An example is shown in which a slave of any one piconet operates as a slave of another piconet in a decentralized network.

[0036] see image 3 , the master station 21 belonging to the first piconet 20 simultaneously operates as the slave station 21 of the master station 31 in the second piconet 30 . In addition if Figure 4 As shown, the slave station 43 belonging to the master station 41 of the first piconet 40 simultaneously operates as a slave station 43 of the master station 51 in the second piconet 50 . For the purposes of the above-mentioned operations, the Bluetooth systems participating in the decentralized network satisfy predetermined rules tentatively determined as follows:

[0037] 1) The transition from communication with a Bluetooth system belonging to any piconet (hereinafter will be referred to as pi...

Abstract

Disclosed is a communication method capable of preventing data collision for a Bluetooth system which communicates with a plurality of other Bluetooth systems on a scatternet. The communication method of a Bluetooth system includes the steps of: receiving a communication request signal from a second external device; scanning the received communication request signal in order to convert the operation of the Bluetooth system from being the master to the first external device into being a slave to the second external device; and transmitting a mode-converting request signal to the second external device in order to convert the link state of the Bluetooth system with the second external device into a sniff mode when converting the operation of the Bluetooth system from being the slave to the second external device into being the master to the first external device.

Description

technical field [0001] The invention relates to a bluetooth system and its communication method, in particular to a bluetooth system capable of communicating with multiple different communication devices in a decentralized network and its communication method. This application is based on Korean Patent Application No. 2002-04104 filed on Jan. 24, 2002, which is hereby incorporated by reference. Background technique [0002] Bluetooth is the code name for a wireless data communication technology used in the telecommunications, networking, computing and consumer product industries. Bluetooth technology allows a wireless link to replace the clutter of cables used to connect devices within short range. For example, if both a cellular phone and a laptop are equipped with Bluetooth wireless technology, it is possible to use the cellular phone and the laptop as linked without a cable. Devices that can be part of a Bluetooth system include printers, personal digital assistants (PD...
