MOBILE DEVICE, COMMUNICATION CONTROL METHOD AND COMMUNICATION CONTROL PROGRAM

PROBLEM TO BE SOLVED: To provide a communication control method for promptly performing transmission or reception of data when a mobile device establishes communication with a communication network. SOLUTION: The mobile device 10 is at least provided with a transmission tray 12, a radio communication network detection part 16 and a radio LAN (local area network) communication part 18. An e-mail E is stored in the transmission tray 12. The radio LAN communication part 18 transmits the e-mail E to a mail server 100 via a radio LAN taking this opportunity that a radio LAN is detected by the radio communication network detection part 16. Preferably, the mobile device 10 is further provided with a radio communication network switching part 17 and a cellular phone network communication part 19. The radio communication network switching part 17 switches a connecting destination of the mobile device 10 from the radio LAN to a cellular phone network when the radio LAN is not detected within prescribed time. The cellular phone network communication part 19 transmits the e-mail E to the mail server 100 via the cellular phone network as the switching destination. COPYRIGHT: (C)2004,JPO&NCIPI
