Abstract

A method for performing communication by a first communication device in a mobile communication system is provided. The method includes determining whether the first communication device is proximate to a nearby second communication device through a short-range communication link, enabling one of a first long-range communication link with a network or the short-range communication link with the second communication device based on the determination as to whether the first communication device is proximate to the second communication device, and receiving data from the network through the enabled one of the first long-range communication link with the network or the short-range communication link.

First claim

What is claimed is:

1 . A method for performing communication by a first communication device in a mobile communication system, the method comprising:
determining whether the first communication device is proximate to a nearby second communication device through a short-range communication link; enabling one of a first long-range communication link with a network or the short-range communication link with the second communication device based on the determination as to whether the first communication device is proximate to the second communication device; and receiving data from the network through the enabled one of the first long-range communication link with the network or the short-range communication link.

2 . The method of claim 1 , wherein the enabling of one of the first long-range communication link with the network and the short-range communication link with the second communication device based on the determination as to whether the first communication device is proximate to the second communication device comprises:
enabling, when the second communication device is not within a proximate distance, the first long-range communication link.

3 . The method of claim 2 , wherein the enabling of one of the first long-range communication link with the network and the short-range communication link with the second communication device based on the determination as to whether the first communication device is proximate to the second communication device comprises:
enabling, when the second communication device is within the proximate distance, the short-range communication link and controlling the second communication device to enable a second long-range communication link with the network.

4 . The method of claim 3 , further comprising:
controlling, upon detecting that the second communication device has turned into a state where the second communication device is out of the proximate distance, the second communication device to disable the second long-range communication link, and receiving data from the network through the first long-range communication link.

5 . The method of claim 4 , further comprising:
controlling, upon detecting that the second communication device has turned into a state where the second communication device is within the proximate distance, the second communication device to enable the second long-range communication link, and receiving data from the network through the short-range communication link.

6 . The method of claim 1 , further comprising: before the enabling of one of the first long-range communication link with the network and the short-range communication link with the second communication device,
making a comparison of priority with the second communication device; determining whether the first communication device is being worn by a user; and determining, depending on a result of the comparison of the priority and the determination of whether the first communication device is being worn by the user, to operate as a connection controller.

7 . The method of claim 6 , further comprising:
discovering at least one communication device positioned around; and determining a communication with a highest priority of a role as a connection enabler among the discovered at least one communication device as a connection enabler.

8 . The method of claim 1 , wherein the first communication device comprises a wearable device.

9 . A first communication device in a mobile communication system, the first communication device comprising:
a controller configured to:
determine whether the first communication device is proximate to a nearby second communication device through a short-range communication link,
enable one of a first long-range communication link with a network or the short-range communication link with the second communication device based on the determination as to whether the first communication device is proximate to the second communication device, and
receive data from the network through the enabled one of the first long-range communication link with the network or the short-range communication link; and
a communication unit configured to communicate data through the long-range communication link or the short-range communication link under the control of the controller.

10 . The first communication device of claim 9 , wherein, when the second communication device is not within a proximate distance, the controller is further configured to enable the first long-range communication link.

11 . The first communication device of claim 10 , wherein, when the second communication device is within the proximate distance, the controller is further configured to enable the short-range communication link and to control the second communication device to enable a second long-range communication link with the network.

12 . The first communication device of claim 11 , wherein, upon detecting that the second communication device has turned into a state where the second communication device is out of the proximate distance, the controller is further configured to:
control the second communication device to disable the second long-range communication link, and receive data from the network through the first long-range communication link.

13 . The first communication device of claim 12 , wherein, upon detecting that the second communication device has turned into a state where the second communication device is within the proximate distance, the controller is further configured to:
control the second communication device to enable the second long-range communication link, and receive data from the network through the short-range communication link.

14 . The first communication device of claim 12 , wherein the controller is further configured to:
make a comparison of priority with the second communication device, determine whether the first communication device is being worn by a user, and determine to operate as a connection controller depending on a result of the comparison of the priority and the determination of whether the first communication device is being worn by the user.

15 . The first communication device of claim 14 , wherein the controller is further configured to:
discover at least one communication device positioned around, and determine a communication with a highest priority of a role as a connection enabler among the discovered at least one communication device as a connection enabler.

16 . The first communication device of claim 9 , wherein the first communication device comprises a wearable device.

17 . A communication device of a mobile communication system, the communication device comprising:
a communication unit configured to communicate data through a communication link; and a controller, electrically coupled with the communication unit, configured to:
control the communication unit to determine whether the communication device is proximate to another communication device through a short-range communication link,
enable one of a first long-range communication link with a network or the short-range communication link with the other communication device based on the determination as to whether the communication device is proximate to the other communication device, and
receive the data from the network through the enabled one of the first long-range communication link with the network or the short-range communication link.

18 . The communication device of claim 17 , wherein the controller is further configured to enable the first
