  • Patent number: 7421577
    Abstract: The present invention provides a means for reflecting modifications made in a server to data with regard to a scope of rights, which are granted to an application program operable in a communication device such as a mobile station, on data stored in the communication device. To achieve the aim, in a system according to the present invention, Java-AP software is provided to a mobile station by transmitting an ADF, a SDF and a JAR file from servers to the mobile station in that order. The SDF is a file containing data indicating restrictions of behavior of a Java-AP in a mobile station. The SDF also contains data indicating a validity state of the SDF, namely ‘valid’ or ‘invalid’, which is managed by management server device 18. Before a mobile station runs a Java-APP which is installed in the mobile station, the mobile station accesses management server device 18 and checks whether a SDF corresponding to the Java-APP is valid.

  • Publication number: 20080177950
    Abstract: 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.

  • Publication number: 20080096485
    Abstract: 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 storage 105 stores combinations of communication profiles which can be simultaneously executed.

  • Publication number: 20080069559
    Abstract: In a method and device which can quickly detect a fiber misconnection without setting an expected value, a node identifier of source node and an identifier of an interface for inputting/outputting a signal are set in a predetermined first field of a header to be transmitted to a destination node, and when both identifiers set in the first field are received from the destination node, both identifiers are set in a predetermined second field of the header to be transmitted and stored with the first field. When the identifiers set in the first and second fields are received and the identifiers of the second field among the identifiers are consistent with the identifiers of the first field stored at the second step (means), a connection is determined to be correct.

  • Publication number: 20050075101
    Abstract: A mobile telephone 2 having a function for downloading and executing an application A from a network server comprises a communications module execution control system 1. The judging section 132 acquires and refers to an attribute information file 14. If the attribute information file 14 contains a (UseTelephone=call) definition, then the judging section 132 judges that the call section 102 is to be executed by the application A, and if there is no UseTelephone key, then it judges that the call section 102 is not be executed by the application A. If the UseTelephone value is not “call”, then the judging section 132 judges that the download of the application A is not allowed. The control section 136 controls the download and execution of the application A, in accordance with the judgement from the judging section 132.
