RADIO COMMUNICATION DEVICE AND RADIO COMMUNICATION METHOD

摘要

A radio terminal (MS) (100) capable of secreting and securing completeness i n layer 2 or higher-order layers and comprising a terminal IF unit (10), a rad io communication control unit (20), a radio communication unit (30), and a secreting/completion-securing unit (40) connected to the terminal IF unit (10), the terminal IF unit (20), and the radio communication unit (30). The secreting/completeness-securing unit (40) only secrets transparent data such as audio data with respect to the terminal IF unit (10) and the radio communication unit (30), secrets non-transparent data and/or secures the completeness of the nontransparent data with respect to the radio communication control unit (20), and selectively secrets data on layer 2 and the higher-order layers outputted from the radio communication unit (30) or secures the completeness of the data according to the type of data.
