Abstract

A communication device includes: a transmission unit configured to transmit a connection request to a first communication device; a reception unit configured to receive a connection permission from the first communication device; and a control unit configured to establish a first connection to the first communication device. The control unit controls a communication of a second communication device.

Claims (18)

1 . A communication device comprising:

a transmitter configured to transmit a connection request to a first communication device;

a receiver configured to receive a connection permission from the first communication device; and

a processor configured to establish a first connection to the first communication device,

wherein the processor controls a communication of a second communication device, and

wherein the connection request includes location information of the communication device itself.

2 . The communication device as claimed in claim 1 , wherein the processor establishes a second connection to an Internet, and establishes a user-plane connection of the second communication device via the second connection.

3 . The communication device as claimed in claim 2 , wherein the connection request includes location information of the second communication device.

4 . The communication device as claimed in claim 2 , wherein the processor controls the first connection by using a timer and determines that the first connection is disconnected in a case where transmission and reception of a signal to and from the first communication device are not completed before an expiration of the timer.

5 . The communication device as claimed in claim 1 , wherein the connection request includes location information of the second communication device.

6 . The communication device as claimed in claim 1 , wherein the processor controls the first connection by using a timer and determines that the first connection is disconnected in a case where transmission and reception of a signal to and from the first communication device are not completed before an expiration of the timer.

7 . The communication device as claimed in claim 6 , wherein the transmitter transmits, to the second communication device, an indication of stopping a function of controlling the wireless communication with the second communication device and a function of performing wireless communication with the second communication device in a case where the first connection is disconnected.

8 . A communication method performed by a communication device, the communication method comprising:

transmitting a connection request to a first communication device;

receiving a connection permission from the first communication device;

establishing a first connection to the first communication device; and

controlling a communication of a second communication device,

wherein the connection request includes location information of the communication device itself.
