Abstract

Provided is a wireless communication device including a communication unit, a storage unit that stores information of one wireless communication device forming a same communication group as the wireless communication device, received by the communication unit, and a control unit that discloses the information of the one wireless communication device during an information disclosure period initiated based on user operation for connecting the one wireless communication device forming the communication group and another wireless communication device and does not disclose the information of the one wireless communication device during another period.

Claims

1. A wireless communication device, wherein the wireless communication device is a first wireless communication device in a communication group, wherein the communication group includes the first wireless communication device and a second wireless communication device wirelessly connected to the first wireless communication device, the first wireless communication device comprising:

a communication unit configured to;

receive information identifying the second wireless communication device; and

receive a disclosure signal transmitted from the second wireless communication device;

a storage unit configured to store the information identifying the second wireless communication device; and

a control unit configured to;

initiate an information disclosure period in response to receiving an indication of a user operation on the second wireless communication device, wherein the disclosure signal received by the communication unit includes the indication of the user operation;

receive a request from a third wireless communication device that is not part of the communication group;

determine whether the information disclosure period has ended;

disclose the information identifying the second wireless communication device to the third wireless communication device based, at least in part, on the determination of whether the information disclosure period has ended; and

terminate the information disclosure period when a connection process between said second wireless communication device and said third wireless communication device reaches a predetermined stage.

2. The wireless communication device according to claim 1, wherein

the control unit is configured to measure an elapsed time from the initiation of the information disclosure period and, after a predetermined time is elapsed, terminate the information disclosure period.

3. The wireless communication device according to claim 1, wherein

the control unit is configured to terminate the information disclosure period when a signal transmitted from said second wireless communication device based on completion of connection between said second wireless communication device and said third wireless communication device is received by the communication unit.

4. The wireless communication device according to claim 1, wherein

the control unit is configured to terminate the information disclosure period when a signal transmitted from said second wireless communication device after transmission and reception of a connection permission message between said second wireless communication device and said third wireless communication device is received by the communication unit.

5. The wireless communication device according to claim 1, wherein

the communication group includes a plurality of wireless communication devices and the storage unit stores information identifying each of the plurality of wireless communication devices in the communication group, and wherein the control unit is further configured to disclose to the third wireless communication device information identifying only wireless communication devices in the communication group associated with an information disclosure period that has not ended.

6. The wireless communication device according to claim 1, wherein

the control unit is further configured to:

determine that the user operation has been performed on the first wireless communication device;

initiate an information disclosure period for the first wireless communication device;

measure an elapsed time from initiation of the information disclosure period for the first wireless communication device; and

after a predetermined time is elapsed, terminate the information disclosure period for the first wireless communication device.

7. A non-transitory storage medium configured to store a computer program that, when executed by a computer incorporated as a portion of a wireless communication device included as a first wireless communication device in a communication group including the first wireless communication device and a second wireless communication device wirelessly connected to the first wireless communication device, performs a method comprising:

storing information identifying the second wireless communication device;

receiving a disclosure signal transmitted from said second wireless communication device;

initiating an information disclosure period in response to receiving an indication of a user operation on the second wireless communication device, wherein the received disclosure signal includes the indication of the user operation;

determining, after receiving a connection request from a third wireless communication device that is not part of the communication group, whether the information disclosure period has ended;

disclosing the information identifying the second wireless communication device to the third wireless communication device based, at least in part, on the determination of whether the information disclosure period has ended; and

terminating the information disclosure period when a connection process between said second wireless communication device and said third wireless communication device reaches a predetermined stage.

8. A wireless communication method comprising steps of

receiving, by a first wireless communication device in a communication group, wherein the communication group includes the first wireless communication device and a second wireless communication device wirelessly connected to the first wireless communication device, information identifying the second wireless communication device;

storing the information identifying the second wireless communication device on a storage medium;

initiating an information disclosure period in response to receiving an indication of a user operation on the second wireless communication device, wherein a disclosure signal transmitted from said second wireless communication device includes the indication of the user operation;

receiving a connection request from a third wireless communication device that is not part of the communication group;

determining whether the information disclosure period has ended;

disclosing the information identifying the second wireless communication device to the third wireless communication device based, at least in part, on the determination of whether the information disclosure period has ended; and

terminating the information disclosure period, when a connection process between said second wireless communication device and said third wireless communication device reaches a predetermined stage.

9. A wireless communication system comprising:

a first wireless communication device; and

a second wireless communication device forming a same communication group as the first wireless communication device, wherein

the first wireless communication device is configured to transmit a signal to the second wireless communication device upon detecting a user operation for making a connection to a third wireless communication device that is not part of the communication group, and

wherein the second wireless communication device includes

a communication unit configured to receive a disclosure signal transmitted from said first wireless communication device,

a storage unit configured to store information identifying the first wireless communication device, and

a control unit configured to;

initiate an information disclosure period in response to receiving an indication of a user operation on the first wireless communication device, wherein the disclosure signal received by the communication unit includes the indication of the user operation;

determine whether the information disclosure period has ended;

disclose to the third wireless communication device, the information identifying the first wireless communication device based, at least in part, on the determination of whether the information disclosure period has ended; and

terminate the information disclosure period, when a connection process between said first wireless communication device and said third wireless communication device reaches a predetermined stage.
