Method, apparatus and system for terminal to connect Bluetooth device, and device

Abstract

The invention discloses a method for a terminal to connect a Bluetooth device, and the method comprises the following steps: more than two terminals build and keep a Bluetooth low energy (Ble) connection with the Bluetooth device; when at least one of the more than two terminals detects an operation which triggers own state to change, the at least one terminal sends a notice message to the Bluetooth device; at least one of the more than two terminals receives a connection state report sent by the Bluetooth device, and according to the received connection state report, sends a connection request to the Bluetooth device on the basis of keeping the Ble connection so as to build a Bluetooth communication connection, wherein the connection request refers to that at least one of the more than two terminals is going to build a conventional Bluetooth communication connection with the Bluetooth device. The invention also discloses an apparatus and a system for the terminal to connect the Bluetooth device, and a device.

Description

technical field [0001] The invention relates to bluetooth communication technology in the field of wireless communication, in particular to a method, device, system and equipment for supporting multi-terminal bluetooth connection. Background technique [0002] In the prior art, a common bluetooth device such as a bluetooth headset or a car bluetooth device can be connected with a mobile terminal such as a mobile phone to complete the function of answering a call. If a Bluetooth headset or a car Bluetooth device is connected using a Bluetooth mobile phone profile (HSP, Headset Profile) or a Bluetooth hands-free profile (HFP, Hands Free Profile) protocol, a Bluetooth headset or a car Bluetooth device can only be connected to one mobile phone at the same time; the latest The HFP protocol can support the connection of two mobile phones at the same time, but the two mobile phones can only use the Bluetooth headset or car Bluetooth device that supports the latest HFP protocol to a...

Problems solved by technology

If a Bluetooth headset or a car Bluetooth device is connected using a Bluetooth mobile phone profile (HSP, Headset Profile) or a Bluetooth hands-free profile (HFP, Hands Free Profile) protocol, a Bluetooth headset or a car Bluetooth device can only be connected to one mobile phone at the same time; the latest The HFP protocol can support the connection of two mobile phones at the same time, but the two mobile phones can only use the Bluetooth headset or car Bluetooth device that supports the latest HFP protocol to answer when any one of the mobile phones is calling (not at the same time); Choose to answer when there is an incoming call at the same time. If two mobile phones call at the same time, the existing technology can only notify the headset or the Bluetooth device on the car.

For the Bluetooth chips used in mobile phones, Bluetooth headsets or car Bluetooth devices that do not support the latest HFP protocol, it cannot support multiple mobile phones and Bluetooth headsets or car Bluetooth devices to connect at the same time

[0003] It can be seen that in the prior art, when the user uses more than two mobile phones, the vehicle-mounted Bluetooth device cannot guarantee to be connected to each mobile phone of the user, and it cannot guarantee that the user chooses to answer the phone call when using the vehicle-mounted Bluetooth device.
