  • Patent number: 7496922
    Abstract: In a communication terminal where a running application is not managed by an OS (operating system), a message is received without a communication connection being established, and if the message is destined for a running application, receipt of the message is notified to the running application. In mobile device MS, CPU 6 writes in key information area 73 of RAM 7 key information for identifying a Java application which is being run using KVM program 84, using OS software 82 and JAM program 86 stored in nonvolatile memory 8. CPU 6, when receiving a SMS message, and further if a content of the message matches the key information written in key information area 73, writes information that the message has been received in an area reserved in RAM 7 for the running Java application.

  • Patent number: 7483690
    Abstract: A mobile phone stores a plurality of profile data, each including a portal URL. A user of the mobile phone selects for use data of a profile including the portal URL. When a Java-AP running on the mobile phone transmits to JAM an instruction for a communication, JAM stores the domain name of the portal URL included in the selected profile data as information about the inhibited destination of a communication performed by the Java-AP. JAM restricts communications performed by a Java-AP on the basis of the information about the inhibited destination stored by JAM. Thus, communications from a Java-AP running on the mobile phone to the server apparatus assigned with the domain name of the portal URL may be inhibited by selection of profile data including a portal URL.
