Description

Method and device for pairing Bluetooth devices

The present invention relates to the field of Bluetooth communication, and more particularly to a method for pairing a Bluetooth device and a device for setting Bluetooth pairing parameters.

When establishing a Bluetooth connection between Bluetooth devices, you first need to set parameters such as Bluetooth address and pairing password, that is, Bluetooth “pairing”. The connection between the two Bluetooth devices without “pairing” cannot establish the physical layer connection. Subsequent authentication connections and operations are not possible.

With the continuous evolution of technology, many wireless communication technologies such as Bluetooth communication are integrated into smart cards such as SIM and USIM, so that mobile terminals such as mobile phones can communicate with smart cards through the 7816 interface, and can also use Bluetooth connection and wisdom. Card communication, which opens up the high-speed data channel between the mobile terminal and the smart card, so that the smart card not only provides telecom functions, but also supports various new applications to download and run through the Bluetooth channel.

Before any Bluetooth connection is established, the Bluetooth pairing parameters of both parties need to be set. For the Bluetooth SIM application scenario, since the Bluetooth SIM card itself does not provide a user input interface, a common practice for setting Bluetooth pairing parameters is in a mobile phone or the like. The application (APP) generates and sets the Bluetooth pairing parameters: the user interface is prompted to input the pairing parameter in the APP interface or the mobile phone APP automatically generates the pairing parameter according to the user input (for example, the mobile phone APP encrypts the user input information and then pairs Parameter), then The pairing parameters are sent to the SIM card through the 7816 interface or data short message to achieve the purpose of Bluetooth pairing; however, there is a certain safety hazard in this way: if there is a malicious code such as a virus, a Trojan or a hacker on the mobile phone, It is possible to intercept the data entered by the user on the APP interface, so there is a potential risk of exposure to the Bluetooth pairing parameters.

The present invention is intended to provide a method for pairing a Bluetooth device and a device for setting Bluetooth pairing parameters, which can more securely set Bluetooth pairing parameters and increase the security of the Bluetooth connection.

The technical solution of the Bluetooth device pairing method in the embodiment of the present invention is implemented as follows.

Step A: The mobile terminal or the smart terminal controls the mobile terminal to pop up the STK menu, and the mobile terminal and the smart card acquire pairing parameter information through the STK menu, and obtain the Bluetooth pairing parameter by using the pairing parameter information.

A preferred solution of the foregoing step A is: prompting to input the pairing parameter information required for the Bluetooth connection by using the pop-up STK menu; the mobile terminal and the smart card adopt the pairing parameter information acquired through the STK menu, or use The mobile terminal and the smart card preset algorithm calculate or transform the pairing parameter information acquired through the STK menu to obtain a Bluetooth pairing parameter.

Another preferred technical solution of the above step A is: confirming the pairing parameter information automatically generated by the system by the pop-up STK menu prompt; the mobile terminal and the smart card are automatically generated by the system after confirmation Pairing parameter information or using a preset algorithm to calculate or transform the pairing parameter information automatically generated by the system to obtain a Bluetooth pairing parameter.

Here, the system refers to a communication system composed of a mobile terminal and a smart card. In actual application, the system can be an operating system of a smart mobile terminal, or a COS of a smart card, COS is a Chip Operating System (on-chip operating system). .

Steps are included before step A: Step B: Check if the mobile terminal and the smart card have completed Bluetooth pairing.

Specifically, after the system is powered on and initialized, the system checks whether the mobile terminal and the smart card in the system complete the Bluetooth pairing. If the mobile terminal and the smart card have completed the Bluetooth pairing, the Bluetooth pairing parameter is automatically used to establish a physical channel and perform subsequent authentication connection and operation according to the requirements of the Bluetooth protocol when the system is powered on.

Further, as a preferred solution, a pairing flag is set in the mobile terminal and/or the smart card, and the checking whether the mobile terminal and the smart card complete the Bluetooth pairing comprises: checking a value of the pairing flag.

As a preferred solution of the embodiment of the present invention, after step A, the method further includes the following steps: Step C: The mobile terminal and the smart card respectively save the Bluetooth pairing parameters as their own Bluetooth pairing parameters, so that the mobile terminal and the smart card are completed again. Bluetooth connection.

After the Bluetooth pairing parameter is determined, it needs to be transmitted between the mobile terminal and the smart card. Specifically, after one of the mobile terminal or the smart card determines the Bluetooth pairing parameter, the Bluetooth pairing parameter needs to be transmitted to the other party.

Another object of embodiments of the present invention is to provide a Bluetooth pairing parameter. The number setting device includes: a system STK module for popping up the STK menu, prompting for input or confirming Bluetooth pairing parameter information.

The parameter determination module is configured to determine Bluetooth pairing parameters of the mobile terminal and the smart card according to the Bluetooth pairing parameter information input or confirmed in the STK menu.

A parameter transmission module is configured to transmit the determined Bluetooth pairing parameters between the mobile terminal and the smart card.

The parameter setting module is configured to set and save the determined Bluetooth pairing parameter as the Bluetooth pairing parameter of the mobile terminal and the smart card respectively.

The method and device for pairing Bluetooth devices provided by the embodiments of the present invention can better prevent Bluetooth pairing by allowing the user to set the pairing parameters required for the Bluetooth connection by using the STK menu, because the malicious program cannot intervene in the input and output of the STK menu. The parameters are maliciously intercepted. In this way, the mobile terminal and the smart card can conveniently determine the Bluetooth pairing parameters, which provides a good foundation for realizing the rapid establishment of the Bluetooth connection and enhancing the security of the Bluetooth connection of the mobile terminal and the smart card.
