Communication terminal containing apparatus, communication terminal apparatus, and radio communication system

The communication terminal accommodation device according to claim wherein priority is given to a connection request in a connection request period immediately following the identification signal just after completion of the period of the distributed control mode.

A communication terminal device for a direct connection network comprising:

• identification signal confirmation means for confirming an identification signal that protects the period of a centralized control mode in a direct connection network;
• and communication control means for initiating communication in the centralized control mode of the direct connection network after the identification signal has been confirmed.

A communication terminal device for a master-slave network wherein said communication terminal device is configured to confirm an identification signal inserted at the timing just after the transmission of an annunciation channel in the master-slave network, or an identification signal inserted at the timing just after a broadcast phase including the annunciation channel in the master-slave network.

A communication terminal device for a master-slave network comprising:

• identification signal confirmation means for confirming an identification signal that protects a centralized control mode of a direct connection network;
• and connection request means for making a connection request during a connection request period provided after the identification signal has been confirmed.
