Method for establishing bluetooth connection and mobile terminal

1. A method for establishing a Bluetooth® connection, comprising:

establishing, by a mobile terminal, at least two data connections with at least two Bluetooth® devices;

sending, by the mobile terminal, a prompt instruction all Bluetooth® devices with which the data connections have been established upon receiving a communication event;

obtaining, by the mobile terminal, a voice connection instruction according to a user's input on the mobile terminal, wherein the voice connection instruction comprises an identification information of a target Bluetooth® device selected by the user from the Bluetooth® devices receiving the prompt instruction; and

establishing, by the mobile terminal, the voice connection between the mobile terminal and the target Bluetooth® device according to the voice connection instruction.

2. The method according to claim 1 , wherein establishing, by the mobile terminal, the at least two data connections with the at least two Bluetooth® devices comprises choosing, by the mobile terminal, the at least two Bluetooth® devices to establish data connections according to a pre-stored rule.

3. The method according to claim 2 , wherein the pre-stored rule comprises at least one of the following: a contact group rule, a time rule, and a priority rule.

4. The method according to claim 1 , wherein sending, by the mobile terminal, the prompt instruction to all of the Bluetooth® devices with which the data connections have been established comprises sending, by the mobile terminal, the prompt instruction to at least two Bluetooth® devices with which the data connection has been established according to the communication event and a pre-stored rule.

5. The method according to claim 1 , wherein before establishing, by the mobile terminal, the at least two data connections with the at least two Bluetooth® devices, the method further comprises performing, by the mobile terminal, a pairing operation with the at least two Bluetooth® devices.

6. The method according to claim 1 , wherein the data connections are Asynchronous Connection-Less (ACL) connections and the voice connection instruction is a Synchronous Connection Oriented (SCO) connection instruction.

7. A mobile terminal, comprising:

a data connection unit configured to establish at least two data connections with at least two Bluetooth® devices;

a receiving unit configured to receive a communication event;

a sending unit configured to send a prompt instruction to all the Bluetooth® devices with which the data connections has been established, wherein the prompt instruction is used to instruct the Bluetooth® devices to prompt a user that the communication event is received;

an obtaining unit configured to obtain a voice connection instruction according to a user's input on the mobile terminal, wherein the voice connection instruction comprises an identification information of a target Bluetooth® device selected by the user from the Bluetooth® devices receiving the prompt instruction; and

a voice connection unit configured to establish a voice connection between the mobile terminal and the target Bluetooth® device according to the voice connection instruction.

8. The mobile terminal according to claim 7 , wherein the obtaining unit further comprises a storage unit configured to pre-store a rule, and wherein the rule comprises at least one of a contact group rule, a time rule, and a priority rule.

9. The mobile terminal according to claim 8 , wherein the data connection unit is configured to establish data connections with the at least two Bluetooth® devices according to the rule.

10. The mobile terminal according to claim 8 , wherein the sending unit configured to send a prompt instruction to at least two the Bluetooth® devices with which the data connections has been established according to the communication event and the rule.

11. A method for establishing a Bluetooth® connection, comprising:

performing, by a mobile terminal, a pairing operation with a plurality of Bluetooth® devices;

searching, by the mobile terminal, for Bluetooth® devices paired,

establishing, by the mobile terminal, Asynchronous Connection-Less (ACL) connections with at least two Bluetooth® devices paired without establishing a Synchronous Connection Oriented (SCO) connection with the Bluetooth® devices paired;

sending, by the mobile terminal, a prompt instruction to all Bluetooth® devices through the established ACL connections upon receiving a communication event;

establishing, by the mobile terminal, SCO connections with all Bluetooth® devices with which ACL connections have been established; and

determining, by the mobile terminal, a target Bluetooth® device which has received the prompt instruction to receive the communication event according to a user's select.

12. The method according to claim 11 , further comprising making unselected Bluetooth® devices mute.

13. The method according to claim 11 , further comprising disconnecting the SCO connections after the communication event ends.

14. The method according to claim 11 , wherein determining, by the mobile terminal, the target Bluetooth® device to receive the communication event according to the user's select comprises determining, by the mobile terminal, the target Bluetooth® device to receive the communication event according to the user's operation on the target Bluetooth® device receiving the prompt instruction.
