Abstract

A communication device has a first communication section that supports a first communication mode having a low communication rate and a second communication section that supports a second communication mode having a higher communication rate than the first communication mode. The communication device includes a packet generation section and a communication control section. The packet generation section generates a first portion containing authentication information used for connection authentication for the second communication mode and a second portion other than the first portion. The communication control section performs control to cause the first communication section to transmit the first portion and to cause the second communication section to transmit the second portion after the connection authentication succeeds using the authentication information contained in the first portion.

Claims

1. A communication device having a first communication section that supports a first communication mode having a low communication rate and a second communication section that supports a second communication mode having a higher communication rate than the first communication mode, the communication device comprising:

a packet generation section configured to generate a first portion containing authentication information used for connection authentication for the second communication mode and a second portion other than the first portion; and

a communication control section configured to perform control so as to cause the first communication section to transmit the first portion and so as to cause the second communication section to transmit the second portion after the connection authentication succeeds using the authentication information contained in the first portion.

2. The communication device according to claim 1, wherein the second portion contains type information indicating a type of application using the second communication mode and option information used for launching an application indicated by the type information, and the type information and the option information are used to launch the application.

3. The communication device according to claim 2, wherein the first portion further includes a list of communication protocols that are usable by the second communication section and a list of option information used for connection authentication for each communication protocol included in the list.

4. A communication method for a communication device having a first communication section that supports a first communication mode having a low communication rate and a second communication section that supports a second communication mode having a higher communication rate than the first communication mode;

the communication method comprising the steps of;

generating a first portion containing authentication information used for connection authentication for the second communication mode and a second portion other than the first portion;

transmitting the first portion by using the first communication section;

performing the connection authentication using the authentication information contained in the first portion; and

transmitting the second portion by using the second communication section, after the connection authentication succeeds.
