Patent number: 8073919Abstract: A mobile terminal, data communication method, and a computer program stored in a computer-readable medium for communicating management data in a more efficient way. A management data communication interface communicates management data regularly with a management server, while an application data communication interface communicates application data with an application server on a demand basis. A data collision detector detects a collision between the management data and application data. If a collision is detected, a priority resolver determines whether to prioritize application data over management data. The management data suppressor suspends the management data communication interface when the priority resolver has determined that application data should be prioritized over management data.Type: GrantFiled: October 5, 2006Date of Patent: December 6, 2011Assignee: Fujitsu LimitedInventors: Kazuki Matsui, Hideto Kihara, Soichi Nishiyama, Yasuhiko Awamoto, Hiroshi Kokubo, Chizu Tuge, Yoshiyuki Ito, Norie Tachibana

Patent number: 7801509Abstract: A computer-readable recording medium storing a data communication program capable of transmitting desired data quickly. The mobile terminal (computer) has the following functions: A data accumulating section accumulates accumulation data to be uploaded to a server 7. A transmission data-generating section generates transmission data that is to be transmitted to the server for making the inquiry and has the accumulation data added thereto. A determination section determines whether or not the mobile terminal is in a state in which the transmission data can be transmitted to the server. A communication scheduler permits a data communication section to transmit the transmission data to the server based on the result of determination of the determination section. The data communication section transmits the transmission data to the server in response to permission of the communication scheduler.Type: GrantFiled: October 27, 2006Date of Patent: September 21, 2010Assignee: Fujitsu LimitedInventors: Kazuki Matsui, Hideto Kihara, Soichi Nishiyama, Yasuhiko Awamoto, Hiroshi Kokubo, Chizu Tuge, Yoshiyuki Ito, Norie Tachibana
