Radio communication apparatus and radio communication method

摘要

A radio communication apparatus executes communication by establishing a communication link according to a security level with other device. The radio communication apparatus sets a security level according to a type of service, and discriminates whether the security level is necessary for the communication with the other device. If the security level is necessary, the communication link according to the security level is established. If the security level is not necessary, security level is lowered and the communication link according to the lowered security level is established.

1. A radio communication apparatus for executing communication by establishing a communication link according to a security level with another device, the apparatus comprising:
a setting unit configured to set the security level according to a type of a service; a first discriminating unit configured to discriminate whether the security level set by the setting unit is necessary for the communication with the other device, in accordance with a type of the other device; a first link establishing unit configured to establish the communication link, according to the security level set by the setting unit, with the other device if the first discriminating unit discriminates that the security level is necessary; a second discriminating unit configured to discriminate whether the other device supports a profile which is to be activated if the first discriminating unit does not discriminate that the security level is necessary; and a second link establishing unit configured to:
suppress establishing the communication link with the other device if the second discriminating unit does not discriminate that the other device supports the profile, andlower the security level set by the setting unit and to establish the communication link, according to the lowered security level, with the other device if the second discriminating unit discriminate that the other device supports the profile.
