ABSTRACT:
When a transmitting mobile radio terminal requires the first subscriber switchboard station to start a packet data communication directed to a receiving mobile radio terminal, the first subscriber switchboard station inquires of a number-management server about a mobile radio terminal-discriminator corresponding to a receiving user's address. When searching out the appropriate mobile radio terminal-discriminator, the number-management server transmits it to the first subscriber switchboard station. When receiving the appropriate mobile terminal-discriminator, the first subscriber switchboard station inquires of the HLR about the second subscriber switchboard station in a location area of which the receiving mobile radio terminal exists. The HLR searches out the second subscriber switchboard station, and transmits information thereon to the first subscriber switchboard station, which establishes a route for the packet data communication between the transmitting and receiving mobile radio terminals.
