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, comprising:

a first communication section that supports a first communication mode having a first communication rate;

a second communication section that supports a second communication mode having a higher communication rate than the first communication mode,

the first communication section configured to receive a first portion of a first communication packet,

the first communication packet containing

the first portion containing authentication information used for a connection authentication for the second communication mode, and a flag, and

a second portion other than the first portion; and

a controller configured to determine whether the first communication packet is divided, based on the flag,

the second communication section configured to receive the second portion after the connection authentication succeeds using the authentication information contained in the first portion,

the controller configured to operate a process based on the second portion.

2. The communication device according to claim 1, wherein the controller is configured to extract parameter information from the second portion and launch an application by using the parameter information.
