Abstract

An electronic device includes a communication module that transmits and receives data based on wireless communication, and a control module configured to select at least one of other electronic devices which have been searched in relation to forming of a communication channel using the communication module based on predefined conditions, or determines a communication connection sequence of the plurality of other electronic devices. Other embodiments including a data transmission and reception method and a storage medium are also disclosed.

First claim

What is claimed is:

1. An electronic device comprising:
a communication module configured to transmit and receive data through wireless communication; and
a controller configured to:
search for other electronic devices through the communication module; and
determine a communication connection sequence to connect each of the other electronic devices based on predefined conditions and a predefined weight value of each of multiple parameters that correspond to the predefined conditions.

2. The electronic device of claim 1 , wherein the controller is configured to:
select at least one of a plurality of the other electronic devices to establish a communication channel with, based on the predefined conditions; or
determine the communication connection sequence of the plurality of other electronic devices based on at least one of:
received signal strengths for the plurality of other electronic devices,
a transmitted and received data error rate with the plurality of other electronic devices,
a distance with the plurality of other electronic devices, a Quality of Service (QoS) with the plurality of other electronic devices,
whether the plurality of other electronic devices move,
whether the electronic device itself moves, or
a history of previous communication connections.

3. The electronic device of claim 2 , wherein the controller is configured to differently put a weight value on at least one of the received signal strength, the data error rate, the distance, the QoS, the history before the communication connection, and movements of the plurality of other electronic devices or the electronic device itself, according to a kind of a currently activated application.

4. The electronic device of claim 2 , further comprising a position information collector module configured to collect current position information,
wherein the controller is configured to calculate distances between the electronic device and the at least one of the other electronic devices.

5. The electronic device of claim 4 , wherein when a specific application is activated, the controller is configured to perform communication connection with a farthest electronic device among the at least one of the other electronic devices.

6. The electronic device of claim 2 , wherein if movement of the electronic device is detected while a specific application is activated, the controller is configured to perform a communication connection with a closest electronic device among the at least one of the other electronic devices.

7. The electronic device of claim 2 , wherein when a specific application is activated, the controller is configured to perform a communication connection with one other electronic device with no movement and a strongest received signal strength among the at least one of other electronic devices.

8. The electronic device of claim 7 , wherein when the specific application is activated, the controller is configured to:
re-perform a search according to a predetermined period if the received signal strength of the at least one of other electronic devices is changed;
release a communication connection with a previous other electronic device, and
perform a communication connection with the other electronic device having the strongest received signal strength among the at least one of other electronic devices.

9. The electronic device of claim 1 , further comprising at least one filter configured to select at least one piece of data that is transmitted or received with the at least one of the other electronic devices based on previously input filter information.

10. The electronic device of claim 9 , wherein the controller comprises a filter-based data processing module configured to select a specific filter according to at least one of a time, a place, and at least one electronic device to be connected for communication among the other electronic devices.

11. The electronic device of claim 9 , wherein the controller further comprises a relation-based data processing module configured to:
divide specific information into data pieces;
sequentially broadcast the data pieces to selected other electronic devices; and
provide a specific event or content to the other electronic devices that sequentially respond to the sequential broadcast or respond to at least a part of the data pieces.

12. A data transmission and reception method using wireless communication comprising:
searching for other electronic devices based on wireless communication;
determining a communication connection sequence to connect each of the other electronic devices based on predefined conditions; and
establishing a communication connection with either a selected at least one of the other electronic devices, or each of the other electronic devices according to the determined communication connection sequence and a predefined weight value of each of multiple parameters that correspond to the predefined conditions.

13. The data transmission and reception method of claim 12 , wherein the determining comprises:
collecting at least one piece of information of a received signal strength, a transmitted and received data error rate, a distance, and a Quality of Service (QoS) of the at least one of the other electronic devices, whether the at least one of other electronic devices moves, and whether the electronic device itself moves, and a history of previous communication connections; and
selecting the at least one of the other electronic devices, or determining the communication connection sequence to connect each of the at least one of the other electronic devices based on the collected information.

14. The data transmission and reception method of claim 13 , further comprising:
differently putting a weight value on the at least one of the received signal strength, the data error rate, the distance, the QoS, the history of the previous communication connections, and the movement of the at least one of other electronic devices or the electronic device itself according to a kind of a currently activated application.

15. The data transmission and reception method of claim 13 , wherein the determining comprises:
performing, when a specific application is activated, communication connection with the other electronic device that is in a farthest distance among the at least one of the other electronic devices; or
performing, when the specific application is activated, communication connection with the other electronic devices that are in a distance farther than a predefined reference value among the other electronic devices.

16. The data transmission and reception method of claim 13 , wherein the determining comprises:
performing, if movement of the electronic device is detected while a specific application is activated, a communication connection with one other electronic device that is in a shortest distance among the other electronic devices; or
performing, if the movement of the electronic device is detected while the specific application is activated, a communication connection with one other electronic device that is in a relatively shorter distance among the other electronic devices.

17. The data transmission and reception method of claim 13 , wherein the selecting or the determining comprises:
performing, when a specific application is activated, a communication connection with one other electronic device with no movement and a strongest received signal strength among the other electronic devices; or
performing, when the specific application is activated, a communication connection with one other electronic device
