Abstract

An electronic apparatus includes a communicator; and a processor configured to: transmit a message including a communication connection order among a plurality of terminals to the plurality of terminals through the communicator, and control the communicator to sequentially perform connections with the plurality of terminals corresponding to association requests respectively received from the plurality of terminals after transmitting the message.

First claim

What is claimed is:

1. An electronic apparatus comprising:
a communicator; and
a processor configured to:
control the communicator to establish first respective connections between a plurality of terminals and the electronic apparatus,
determine that the first respective connections between the plurality of terminals and the electronic apparatus have been disconnected,
control the communicator to transmit a communication connection order message, including a communication connection order for the plurality of terminals, from the electronic apparatus to the plurality of terminals,
receive respective association requests through the communicator from the plurality of terminals in response to the transmitted communication connection order message, and
control the communicator to sequentially establish second respective connections with each of the plurality of terminals based on the received respective association requests.

2. The electronic apparatus according to claim 1 , wherein the processor is configured to control the communicator to establish a communication connection with a first terminal of the plurality of terminals, and establish a communication connection with a second terminal of the plurality of terminals after the communication connection with the first terminal of the plurality of terminals is established.

3. The electronic apparatus according to claim 1 , wherein the processor is configured to determine that the first respective connections between the plurality of terminals and the electronic apparatus have been disconnected when the electronic apparatus is rebooted.

4. The electronic apparatus according to claim 1 , further comprising a memory configured to store association information about the first respective connections between the plurality of terminals and the electronic apparatus,
wherein the processor is configured to determine the communication connection order for the plurality of terminals based on the association information stored in the memory.

5. The electronic apparatus according to claim 1 , wherein the processor is configured to control the communicator to transmit the communication connection order message in a broadcast mode.

6. The electronic apparatus according to claim 1 , wherein the communication connection order message comprises respective media access control (MAC) addresses of each of the plurality of terminals for identifying each of the plurality of terminals.

7. The electronic apparatus according to claim 1 , wherein the association information comprises respective information about at least one of a data rate, a communication point in time, and a communication frequency of each of the plurality of terminals.

8. The electronic apparatus according to claim 1 , wherein the processor is configured to control the communicator to transmit the communication connection order message with preset identification information for use by the plurality of terminals to identify whether data received therein corresponds to the communication connection order message.

9. A terminal apparatus comprising:
a communicator; and
a processor configured to:
control the communicator to establish a first connection with an electronic apparatus,
determine that the established first connection with the electronic apparatus has been disconnected,
receive a communication connection order message, including a communication connection order for a plurality of terminals including the terminal apparatus, through the communicator from the electronic apparatus, and
control the communicator to transmit, to the electronic apparatus at a time indicated by the communication connection order for the terminal apparatus, an association request in response to the received communication connection order message.

10. The terminal apparatus according to claim 9 , wherein the processor is configured to control the communicator to transmit the association request at a point in time corresponding to the communication connection order and delayed from a point in time of receiving the communication connection order message.

11. A method of controlling an electronic apparatus, the method comprising:
performing, by a processor of the electronic apparatus, operations including:
controlling a communicator of the electronic apparatus to establish first respective connections between a plurality of terminals and the electronic apparatus;
determining that the first respective connections between the plurality of terminals and the electronic apparatus have been disconnected;
controlling the communicator to transmit a communication connection order message, including a communication connection order for the plurality of terminals, from the electronic apparatus to the plurality of terminals; and
control the communicator to sequentially establish second respective connections with each of the plurality of terminals based on association requests respectively received from the plurality of terminals in response to the transmitted communication connection order message.

12. The method according to claim 11 , wherein the operations further include controlling the communicator to establish a communication connection with a first terminal of the plurality of terminals, and establish a communication connection with a second terminal of the plurality of terminals after the communication connection with the first terminal of the plurality of terminals is established.

13. The method according to claim 11 , wherein the operations further include determining that the first respective connections between the plurality of terminals and the electronic apparatus have been disconnected when the electronic apparatus is rebooted.

14. The method according to claim 11 , wherein the operations further include determining the communication connection order for the plurality of terminals based on stored association information about the first respective connections between the plurality of terminals and the electronic apparatus.

15. The method according to claim 11 , wherein the communication connection order message is transmitted in a broadcast mode.

16. The method according to claim 11 , wherein the communication connection order message comprises respective media access control (MAC) addresses of each of the plurality of terminals for identifying each of the plurality of terminals.

17. The method according to claim 11 , wherein the association information comprises respective information about at least one of a data rate, a communication point in time, and a communication frequency of each of the plurality of terminals.

18. The method according to claim 11 , wherein the operations further include controlling the communicator to transmit the communication connection order message with preset identification information for use by the plurality of terminals to identify whether data received therein corresponds to the communication connection order message.

19. A method of controlling a terminal apparatus, the method comprising:
performing, by a processor of the terminal apparatus, operations including:
controlling a communicator of the terminal apparatus to establish a first connection with an electronic apparatus;
determining that the established first connection with the electronic apparatus has been disconnected;
receiving a communication connection order message, including a communication connection order for a plurality of terminals including the terminal apparatus, through the communicator from the electronic apparatus; and
controlling the commun
