Embodiment Construction

[0065] The present invention will be further described below in conjunction with accompanying drawing.

[0066] The method and system for realizing global free roaming based on bluetooth equipment of the present invention, the bluetooth equipment adopted in it is divided into bluetooth SIM card and bluetooth smart equipment.

[0067] Such as figure 1 Shown is the internal schematic diagram of the custom-made Bluetooth SIM card of the present invention; the main difference between the Bluetooth SIM card and the ordinary SIM is that the Bluetooth SIM card has a built-in Bluetooth system, and the 7816 protocol for sending and receiving by metal contacts is all forwarded to the SIM through the Bluetooth control chip The COS system can also be forwarded directly through the 2.4G Bluetooth radio frequency through the Bluetooth chip. In this way, Bluetooth supports two sets of interfaces, one is a physical contact interface, and the other is a Bluetooth wireless interface. At the s...
