There are provided: a data communication system, a relay apparatus, and a portable terminal apparatus in which when a mobile portable terminal apparatus such as a mobile telephone displays a screen based on display screen definition data received from a central apparatus, the exception handling of the data communication can be dynamically changed according to the communication environment of the portable terminal apparatus. The central apparatus adds, to the display screen definition data, communication control data where an exception handling procedure for communication between the portable terminal apparatus and the central apparatus is set. The portable terminal apparatus displays an image based on the display screen definition data received from the central apparatus, and performs data communication with the central apparatus according to the communication control data extracted from the display screen definition data.

A security management program stored in a computer-readable recording medium causes a computer to perform the following steps (1) to (4). (1) A security manager authenticates an authentication target with a prepared authentication method in response to a login request from the authentication target. (2) An application execution unit outputs an authentication request in response to an application execution request which is output from the security manager after the authentication succeeds. (3) A database access unit authenticates the authentication target with the authentication method in response to the authentication request. (4) In response to a database access request from the application execution unit, the database access unit accesses a database in a portable terminal device depending on the authentication performed by the database access unit.

Security management program, security management method, and portable terminal device

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.

Computer-readable recording medium containing application management program, and method and apparatus for application management

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.

Mobile terminal, method, and computer program for communicating data with servers with data collision control

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. 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.

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.
