Problems solved by technology

Therefore, when a Bluetooth device joins a Bluetooth network, if it needs to exchange IP data with other Bluetooth devices outside the Bluetooth network, it must first exit the existing Bluetooth network to form a new Bluetooth network with other Bluetooth devices, which leads to its All operations and data flow with Bluetooth devices in the original Bluetooth network are interrupted
Inconvenient for users to use, and cannot fully utilize the role of bluetooth

Embodiment Construction

[0040] figure 1 is a scene diagram of a sample NAP connection.

[0041] Wherein, the network access point 104 is connected to the LAN 105 by wire, and the LAN 105 is connected to the Internet 106 . Computers 101 , 102 and PDA PANU device 103 access networks 105 and 106 through NAP device 104 .

[0042] figure 2 is a scene diagram of an example GN connection.

[0043] Device 201 provides GN service and operates as the master device of piconet. Computers 202, 203, 204, 205, 206 and PDAs 207, 208 join the Bluetooth local area network as slave devices. These seven slaves represent the usual number of valid slaves in a Bluetooth network.

[0044] image 3 It is an example structural block diagram of the bluetooth system of the present invention supporting multiple sets of bluetooth network connections at the same time.

[0045] This architecture follows the multi-layer Bluetooth network protocol stack in the PAN context. The key design is the network card application strat...

Abstract

The invention discloses a method for the same bluetooth system to simultaneously support multiple sets of bluetooth network connections. The method includes that different PAN roles on the same device participate in different bluetooth network connections, and different bluetooth network connections use different connection implementation methods.

Description

technical field [0001] The invention relates to a method for forming an IP network between bluetooth devices, in particular to a method for forming multiple groups of personal area networks (or Ad-hoc temporary networks) with bluetooth devices, which belongs to the communication field. technical background [0002] Bluetooth (Bluetooth), which works in the ISM (Industrial Scientific Medical) frequency band of 2.4GHz. Bluetooth is specifically planned for small mobile devices such as notebook computers, mobile phones and personal digital assistants (PDAs). According to the Bluetooth specification developed by the Special Interest Group (SIG), the basic network structure of Bluetooth is a piconet (Piconet) composed of a master device and up to seven slave devices. Communication is carried out by means of time division multiple access (TDMA). By integrating the Bluetooth communication module, various devices can be connected at low cost. Bluetooth devices establish Bluetooth...
