Wireless communication system, wireless communication device, wireless communication method, and program

A first wireless communication device that performs of one of indirect communication with a second wireless communication device via a base station and direct communication with the second wireless communication device without passing via the base station, comprising:

• an acquisition portion that obtains at least two different mutually compatible communication functions with which the first wireless communications device and the second wireless communication device is compatible;
• a transmitting portion that transmits by both the direct communication and indirect communication at least two data frames each comprising at least one of audio data, visual data, video game data, and software using at least two of the at least two mutually compatible communication functions;
• and
• a determination portion that, based on a communication quality of the at least two data frames measured by the second wireless communication device to determine whether to perform the indirect communication or the direct communication.

A first wireless communication device that performs of one of indirect communication with a second wireless communication device via a base station and direct communication with the second wireless communication device without passing via the base station, comprising:

• a transmitting portion that transmits to the second wireless communication device at least two mutually compatible communication functions;
• a receiving portion that receives at least two data frames each comprising at least one of audio data, visual data, video game data, and software transmitted from the second wireless communication device using at least two of the at least two mutually compatible communication functions;
• and
• a measuring portion that measures a communication quality of the at least two data frames received by the receiving portion for each of the at least two mutually compatible communication functions used;
• wherein
• the transmitting portion transmits the communication quality measured by the measuring portion to the second wireless communication device.

A wireless communication method used by a wireless communication system that comprises a first wireless communication device, a second wireless communication device, and a base station that relays wireless communication between the first and the second wireless communication devices, the wireless communication method comprising the steps of:

• acquiring, by the first wireless communication device at least two different mutually compatible communication functions with which the first wireless communication device and the second wireless communication device are compatible;
• transmitting by both direct communication and indirect communication from the first wireless communication device, at least two data frames each comprising at least one of audio data, visual data, video game data, and software using at least two of the at least two mutually compatible communication functions;
• measuring, by the second wireless communication device, communication quality of the at least two data frames transmitted from the first wireless communication device for both the direct communication and the indirect communication;
• and
• determining, by one of the first communication device and the second wireless communication device, whether to establish communication by the indirect communication or the direct communication between the first wireless communication device and the second wireless communication device, based on a determined communication quality of each of the at least two mutually compatible communication functions.

A non-transitory program comprising instructions that command a computer, that is a wireless communication device that performs one of indirect communication with another wireless communication device via a base station and direct communication with the other wireless communication device that does not pass via the base station, to function as a:

• selection portion that selects at least two different mutually compatible communication functions with which the first wireless communication device and the second wireless communication device are compatible;
• a transmitting portion that transmits by both direct communication and indirect communication at least two data frames each comprising at least one of audio data, visual data, video game data, and software using the at least two mutually compatible communication functions selected by the selection portion;
• and
• a determining portion that determines whether to establish communication by the indirect communication or the direct communication between the first wireless communication device and the second wireless communication device, based on communication quality of the transmitted at least two data frames measured by the second wireless communication device for each of the at least two mutually compatible communication functions used.
