An object is to switch executions of applications appropriately from one to another when a plurality of applications use a limited resource. A mobile device () is provided with an execution state shift unit () for shifting an execution state between a multiplex-execution state and a single-execution state in a multi-application execution environment, a resource release unit () for releasing a resource used by applications being executed in the multi-application execution environment, an application stop unit () for stopping an application other than the application to be executed in the single-execution state, and a resource allocation unit () for allocating the resource released by the resource release unit () to the application to be executed in the single-execution state when the execution state is shifted from the multiplex-execution state to the single-execution state by the execution state shift unit ().

Mobile device and application switching method

A technique for easily realizing data communication without limiting the application layer protocol during data communication while maintaining the proxy function. A mobile communication terminal () includes a control protocol processing section () which transmits an address request to a proxy device () to acquire global address information using the HTTP that is preset so as to be used by the mobile communication terminal () and the proxy device (), a TCP/UDP data transmitter/receiver section () which establishes a connection with the proxy device (), and an application section () which transmits data via a communication path between the proxy device () and a server device () using the global address information as the transmitter address. The control protocol processing section () transmits information relating to the connection destination of the server device () to the proxy device () using the HTTP, and requests a connection between the proxy device () and the server device () using a predetermined transport layer protocol.

Data communication terminal, proxy device, data communication system, and data communication method

An event queue managing module that prevents unnecessary events from continuously executing applications when an application execution environment resumes from a suspended state, and including: a queue managing unit for storing event objects reported from an event detector of a basic software unit into an event queue in order of occurrence of events and managing their queue; an event classification detection unit for detecting the event classification and parameter of the event objects whose queue is managed by the queue managing unit; a stop state detection unit for detecting a stop state of an application execution environment; and an event deletion unit for deleting an unnecessary event from the event objects stored in the event queue when the application execution environment is in the stop state.

Event queue managing device and event queue managing method

An object of the invention is to provide a charging processing device and a charging processing method capable of performing an appropriate charging process even when a connectionless protocol, such as UDP, is used. Gateway unitsandtransmit data transmitted between a mobile apparatusand a serverto the mobile apparatusor the serveras a transmission destination, and a charging processing unitperforms a charging process according to the amount of data transmitted by the gateway unitsand. A detecting unitdetects whether response data is transmitted from the transmission destination. When the timer value of the time for which communication is not performed is more than a predetermined time and the detecting unitdoes not detect the response data from the transmission destination, the control unitmay control the gateway unitorto stop the transmission process and control the charging processing unitto stop the charging process.

Data relay device and data relay method

Mobile unitwhich can activate Java-AP software receives SDF (Security Descriptive File)from administering server unitwhich a trustworthy organization (a communication provider which administers mobile packet communication network) administers, and obtains ADFfrom IP server unitby using URL contained in the SDF, and obtains Jar filefrom IP server unitby using ADF, and installs in itself Java-AP containing these files. Java-AP, which is achieved by activating the installed Java-AP software, operates within the range of authorization expressed by policy information contained in SDF

Contents transmission method and contents transmission system

It is an object of the present invention to provide an information processing device and a memory management method that enable execution of memory management processing for simultaneously starting up two types of applications. During execution of an application in the form of a Java application, the application starts up another an application in the form of Flash data, and then a native software in the form of a Flash Player causes a memory management unit to secures a prescribed memory area from a memory area for the native software. A native software then starts up the other application using the secured memory area.

Information processing device and memory management method

A positioning control device includes a GPS hardware control unit that makes GPS determine a current location at different positioning accuracies, and a positioning request management unit that makes the GPS hardware control unit carry out positioning in response to a positioning request from an application according to a positioning accuracy specified in the positioning request, acquires the positioning result, and returns the acquired positioning result to the application of the request origin. In a case where a positioning accuracy of a new positioning request is equal to or less than a positioning accuracy of a latest positioning result, the positioning request management unit reuses the latest positioning result and returns the latest positioning result in response to the new positioning request.

Positioning control device and positioning control method

The present invention provides an information processing device for estimating usage of contents and properly limiting functions realized through use of the contents in accordance with the estimation. Usage of contents is estimated by determining in which of cache memory means and content storage means the contents are stored. When the contents are processed or executed, it is determined whether to limit functions realized through processing or execution of the contents, on the basis of the estimated usage of the contents and function limit information showing a rule regarding limits on functions realized through processing or execution. On the basis of the determination, the functions realized through processing or execution of the contents are limited.

Information processing device and program

When a native application and a downloaded application installed on a mobile equipment are simultaneously executed by multitask and when these applications try to use short-range wireless communication simultaneously, the short-range wireless communication may be unavailable because of restrictions on communication resources. An object of the invention is to provide a wireless communication apparatus and wireless communication method capable of performing communication management to permit the applications to use the short-range wireless communication, without a need for a complicated operation of especially terminating an application to release a communication resource in the foregoing case. A communication profile storagestores combinations of communication profiles which can be simultaneously executed. A short-range wireless communication management unitdetermines whether a communication process according to an instruction from an external applicationcan be executed, based on the communication profiles. When the short-range wireless communication process is determined not to be executed, a disconnection unitnotifies the external applicationof unavailability of the communication.
