Abstract: A computer-readable recording medium containing an application management program for automatically performing version management to surely manage versions of a client application that communicates with a server application. A communication request monitor acquires a communication request issued from a terminal device to a server, and extracts version information of a client application from the communication request. An upgrade determination unit determines whether the extracted version information shows the latest version, and determines that upgrade is necessary if the version is not the latest version. A setting file transmitter sends the communication request to the server if the upgrade determination unit does not determine that the upgrade is necessary. If the upgrade is necessary, on the contrary, the setting file transmitter discards the communication request and sends the client application setting file for the latest version to the terminal device sending the communication request.

Abstract: 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.

Abstract: A technique enabling several kinds of contents information to be used in terminals like cellular phones, regardless of the type of terminals without burdening contents providers. A contents conversion server receives, from a terminal, access destination information such as a URL of a contents providing server, and type information on the terminal or on its browser. Next, if the access destination information is interpreted to point to contents information not in the contents conversion server, but in the contents providing server, as an access destination, the contents conversion server obtains the pointed to contents information from the contents providing server. Then, the contents conversion server converts an arbitrary type of obtained contents information, based on the type of information, and moreover, converts the link information, if included, in accordance with a predetermined rule. Consequently, the contents conversion server sends converted contents information to the terminal.

Abstract: A computer-readable recording medium having recorded therein a telephone-call connection program for controlling telephone calling with the schedule of the other party of a call and a call importance level therefor being taken into account. A connection-request receiving block extracts a transmission-source telephone number and a transmission-destination telephone number and identifies the other party of the call from the transmission-destination telephone number. Then, a call-importance-level determination block determines the call importance level of the call for the other party of the call. A schedule determination block determines whether the current time falls in a response-rejection time zone of the other party of the call. A connection determination block determines according to the response-rejection time zone and the call importance level whether telephone calling is necessary.
