Abstract: A device (45) receives new program files (46) and uses pre-internalized images to avoid having to internalize a program file every time that program execution occurs. In one embodiment, a software Virtual Machine (50) in the device functions to implement the pre-internalization. Once the program files are pre-internalized to create images that are stored in a permanent memory (56) of the device, the images may subsequently be executed without having to perform a pre-internalization operation. Additionally, use of dynamic memory (52) is reduced in connection with subsequent program execution and execution time of new program files is reduced.

Abstract: A communications system (100) has a client device (102) such as a cell phone that can run application suites such as games. The application suites have a core and a plurality of extensions. The application suites can run with less than all of the extensions. If a user desires an additional extension and its attendant functionality, perhaps during application execution, the user of the client device (102) is informed of the cost of the extension and the storage requirements. The user then can choose to submit a request, via a demodulator/modulator (114), for the extension. A server device (104) responds to the request via a demodulator/modulator by transmitting the extension, updates its records as to the status of the client device, and may submit a bill to the user for transmitting the extension.
