In a PHS terminal (4a), a system calling code for identifying a system in which the PHS terminal (4a) is registered and a slave ID number for discriminating the PHS terminal are stored in advance in an ID chip (28). While a user is out, he or she sets the ID chip (28) in another PHS terminal (4b) which does not have the same system calling code as that of the PHS terminal (4a). When the user performs an operation for peer-to-peer communication on the PHS terminal (4a), the PHS terminal (4b) is called using a controlling physical slot. The PHS terminal (4b) recognizes that it is called by discriminating a system calling code and a PS calling number of the physical slot on the basis of the system calling code of the ID chip (28), and then transmits a response signal to the PHS terminal (4a) based on the system calling code and PS calling number of the ID chip (28). Thus, peer-to-peer communication can be performed even between radio communication terminal (4)s which do not have the same system calling code. <IMAGE> |
