1. A radio communication control method for controlling transmission of a data stream by a source apparatus to a sink apparatus in a radio cell, the method comprising:
- determining processing power of the sink apparatus according to services supported by the sink apparatus based on a self-assessment by the sink apparatus;
classifying, based on the processing power, the sink apparatus as either a first type or a second type;
obtaining a device class from the sink apparatus;
comparing the device class to the classified first type or the classified second type;
selecting, based on the processing power when the device class matches the classified first type or the classified second type, an authentication system for authenticating the source apparatus and the sink apparatus, wherein authentication comprises;
selecting a first authentication method for the first type of sink apparatus; and
selecting a second authentication method for the second type of sink apparatus; and
communicating with the sink apparatus based on the selected first authentication method or the selected second authentication method.

Abstract
When transmitting data such as audio data which require protection to be provided, difficulty levels of authentication are switched corresponding to processing power of equipments to communicate. Thus, for an equipment of low processing power may perform a Bluetooth communication based on the SDMI. Further, for a communicating counterparty which is an equipment of high processing power, such as a personal computer, sufficient countermeasures against hacking may be taken.
