摘要： A wireless communication terminal including a wireless communication unit for receiving and transmitting voice signals between terminals connected through a voice channel and a data channel, a signal input/output unit for inputting and outputting voice signals for voice communication and a mixing unit, interposed between the wireless communication unit and signal input/output unit, for performing mixing operations to create a first mixed signal to be output to said signal input/output unit and second mixed signals each to be transmitted to the corresponding terminal. The wireless communication terminal is preferably used for wireless voice communication performed by three or more terminals without being interposed by a center apparatus (such as a server) or a repeater. Further, signal-receiving/transmitting is set for each wireless communication terminal whereupon convenience can be improved.

摘要： A communication apparatus includes an encryption key generation unit that generates encryption key information at constant encryption key generation intervals, a common key generation unit that generates common key information uniquely with respect to a generation time at common key generation intervals set longer than the encryption key generation intervals, a common key application unit that performs encryption or decryption of the encryption key information by using the common key information, and an encryption key distribution unit that makes a request to a data transmitting/receiving unit to distribute the encryption key information to a plurality of communication apparatuses to be communicated simultaneously at encryption key distribution intervals set shorter than the encryption key generation intervals to perform communication with higher security.

摘要： A communication device includes a data storage unit, a decryption unit, an encryption unit, and a judgment unit. The data storage unit stores a piece of encrypted data or a piece of decrypted data. The decryption unit decrypts each provided piece of encrypted data. The encryption unit encrypts each provided piece of decrypted data. The judgment unit issues an instruction to the encryption unit to read from the data storage unit first decrypted data obtained by the decryption unit decrypting first encrypted data with a cryptographic key, and to write back to the data storage unit second encrypted data obtained by the encryption unit encrypting the first decrypted data with the cryptographic key.

摘要： A packet processing method includes the steps of deciding whether or not a packet has the same contents as a packet that has been processed before the packet (MAC-e PDU) generated based on data received by branches from a mobile terminal (#120), dividing the packet into ES packets of a unit of MAC-es PDU (#121) if the packet is decided not to have the same contents (No in #120), deciding whether or not each ES packet obtained by the division should be a transmission object to a core network (#124), and transmitting the ES packet that is decided to be the transmission object to the core network. In this case, the packet decided to have the same contents in the decision of the step #120 is discarded without performing the processes of the division in the step #121, the decision of the step #124 and the like.
