<p>PROBLEM TO BE SOLVED: To provide a mobile packet communication system where mobile communication terminals can transmit/receive packet data in one mobile packet network not through an external network so as to reduce missing or delay or the like of packet data. SOLUTION: When a mobile communication terminal 1 transmits a packet communication request to a subscriber switch station 22, the subscriber switch station 22 inquires of a number management server 32 about a destination address 1b. The number management server 32 retrieves a mobile communication terminal identifier corresponding to the destination address and returns a mobile communication terminal identifier 2B to the subscriber switch station 22 when finding out the concerned mobile communication terminal identifier 2B. The subscriber switch station 22 receiving the mobile communication terminal identifier 2B connects with a subscriber switch station 23 in which a mobile communication terminal 2 exists on the basis of the mobile communication terminal identifier 2B, and the mobile communication terminal 1 transmits packet data to the mobile communication terminal 2 via the subscriber switch stations 22, 23.</p> |
