Wireless communication device, program, and wireless communication system
First Claim
1. A wireless communication device comprising:
- circuitry configured tocontrol a process of detecting a nearby wireless communication device, the process comprisingforming a communication group with the detected nearby wireless communication device in compliance with Wi-Fi P2P,receiving, from the nearby wireless communication device, a first attribute information included in content data in the nearby wireless communication device, wherein the first attribute information comprises an identifier or an update time of the content data,comparing the first attribute information with a second attribute information included in content data stored in the wireless communication device, anddetermining whether one of the content data in the wireless communication device or the content data in the nearby wireless communication device has been updated relative to the other based on a result of the comparison, anddetermine, based on a result of the determination regarding the update, whether to prevent a start of a connection process, for establishing a connection with the detected nearby wireless communication device to share the content data in the wireless communication device or the content data in the detected nearby wireless communication device with the detected nearby wireless communication device,wherein the first attribute information and the second attribute information are communicated using a Service Discovery Query in procedures of Service Discovery defined in Wi-Fi Direct.

Abstract
There is provided a wireless communication device including a wireless communication unit, a communication control unit configured to control a process of detecting a nearby wireless communication device by the wireless communication unit, a connection process to the nearby wireless communication device detected in the detection process, and communication of content data with the nearby wireless communication device connected in the connection process, and a storage unit that stores content data. The communication control unit, on the basis of information received from the nearby wireless communication device in the detection process, determines if one of the content data in the storage unit or content data in the nearby wireless communication device has been updated relative to the other, and controls the connection process performed when the update is determined.

11. A wireless communication method, the method being executed via at least one processor having circuitry, and comprising:
-
controlling a process of detecting a nearby wireless communication device, the process comprising; forming a communication group with the detected nearby wireless communication device in compliance with Wi-Fi P2P; receiving, from the nearby wireless communication device, a first attribute information included in content data in the nearby wireless communication device, wherein the first attribute information comprises an identifier or an update time of the content data; comparing the first attribute information with a second attribute information included in content data stored in a wireless communication device; and determining whether one of the content data in the wireless communication device or the content data in the nearby wireless communication device has been updated relative to the other based on a result of the comparison; and determining, based on a result of the determination regarding the update, whether to prevent a start of a connection process, for establishing a connection with the detected nearby wireless communication device to share the content data in the wireless communication device or the content data in the detected nearby wireless communication device with the detected nearby wireless communication device, wherein the first attribute information and the second attribute information are communicated using a Service Discovery Query in procedures of Service Discovery defined in Wi-Fi Direct.

12. A non-transitory computer-readable storage medium having stored thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
-
controlling a process of detecting a nearby wireless communication device, the process comprising; forming a communication group with the detected nearby wireless communication device in compliance with Wi-Fi P2P; receiving, from the nearby wireless communication device, a first attribute information included in content data in the nearby wireless communication device, wherein the first attribute information comprises an identifier or an update time of the content data; comparing the first attribute information with a second attribute information included in content data stored in a wireless communication device; and determining whether one of the content data in the wireless communication device or the content data in the nearby wireless communication device has been updated relative to the other based on a result of the comparison; and determining, based on a result of the determination regarding the update, whether to prevent a start of a connection process, for establishing a connection with the detected nearby wireless communication device to share the content data in the wireless communication device or the content data in the detected nearby wireless communication device with the detected nearby wireless communication device, wherein the first attribute information and the second attribute information are communicated using a Service Discovery Query in procedures of Service Discovery defined in Wi-Fi Direct.
