Abstract

According to one embodiment, there is provided information processing apparatus, including: a first communication module configured to perform a communication under a first communication scheme which corresponds to a proximity wireless communication requiring no authentication; a second communication module configured to perform a communication under a second communication scheme which has a communicable distance longer than that of the proximity wireless communication; and a communication controller configured to perform a control, after the first communication module has started a data transmission with another information processing apparatus under the first communication scheme, so as to change-over the first communication scheme to the second communication scheme and then perform the data transmission.

Claims

1. An information processing apparatus comprising:

a first communication module configured to communicate under a first communication scheme comprising;

a first communicable distance; and

a first transfer rate,

the first communication scheme requiring no authentication;

a second communication module configured to communicate under a second communication scheme comprising;

a second communicable distance longer than the first communicable distance; and

a second transfer rate lower than the first transfer rate,

the second communication scheme requiring an authentication using authentication information; and

a communication controller configured to;

upon detecting the information processing apparatus within the first communicable distance to another information processing apparatus, establish a wireless connection with the another information processing apparatus under the first communication scheme,

determine whether a size of data as a transmission subject exceeds a threshold value,

when the size of the data is determined to be equal to or smaller than the threshold value, perform the data transmission to the another information processing apparatus under the first communication scheme, and

when the size of the data is determined to be larger than the threshold value, transfer the authentication information to the another information processing apparatus under the first communication scheme and perform the data transmission to the another information processing apparatus under the second communication scheme.

2. The apparatus of claim 1, wherein the second communication scheme is BLUETOOTH™

or WLAN.

3. The apparatus of claim 1, wherein the communication controller is further configured to, upon establishment of the wireless connection with the another information processing apparatus under the first communication scheme, display a user selection screen to allow a user to select whether or not to perform the data transmission under the second communication scheme.

4. The apparatus of claim 1, wherein the communication controller is further configured to, upon re-placing of the information processing apparatus proximally to the another information processing apparatus during the data transmission under the second communication scheme, change into the data transmission under the first communication scheme.

5. A communication control method of controlling an information processing apparatus comprising a processor and a non-transitory memory, the memory storing an OS and a program, the OS enabling the information processing apparatus to, upon detecting the information processing apparatus within a first communicable distance to another information processing apparatus, establish a wireless connection with the another information processing apparatus under a first communication scheme, the first communication scheme requiring no authentication and comprising the first communicable distance and a first transfer rate, and to perform a data transmission to the another information processing apparatus under the first communication scheme and a data transmission to the another information processing apparatus under a second communication scheme, the second communication scheme requiring an authentication using authentication information and comprising a second communicable distance longer than the first communicable distance and a second transfer rate lower than the first transfer rate, the method comprising:

upon establishment of the wireless connection with the another information processing apparatus under the first communication scheme, determining whether a size of data as a transmission subject exceeds a threshold value, by the program;

when the size of the data is determined to be equal to or smaller than the threshold value, instructing the OS to perform the data transmission to the another information processing apparatus under the first communication scheme, by the program; and

when the size of the data is determined to be larger than the threshold value, instructing the OS to transfer the authentication information to the another information processing apparatus under the first communication scheme and to perform the data transmission to the another information processing apparatus under the second communication scheme, by the program.

6. The method of claim 5, wherein the second communication scheme is BLUETOOTH™

or WLAN.

7. The method of claim 6, further comprising, upon establishment of the wireless connection with the another information processing apparatus under the first communication scheme, displaying a user selection screen to allow a user to select whether or not to perform the data transmission under the second communication scheme.

8. The method of claim 7, further comprising, upon re-placing of the information processing apparatus proximally to the another information processing apparatus during the data transmission under the second communication scheme, changing into the data transmission under the first communication scheme.
