Definitions

• a unique address of the terminal, to which the software and the software status is to be transferred is transmitted to the software so that it is also reliably transferred to the correct destination.
• This address can either already be saved or can be entered by the user.
• JAVA is used as the runtime environment.
• FIGS. 1 and 2 show a first simple example for keeping software sof or software states current on several end devices PEC, PAL.
• a user has, for example, a desktop computer PEC and, on the other hand, also a handheld device PAL.
• PAL handheld device
• each of these devices PAL, PEC no longer runs its own software for a specific application, such as for contact management, which is then used on each of the devices PEC for each new or changed entry.
• PAL would have to be adjusted again on the other device, but the user "only" has an executable software application for the respective specific application, which is transferred between the individual devices PEC, PAL on request.
• the master agent After the requested software (the master agent) has received the requests, it then initiates the necessary steps for its migration to the other end device.
• FIGS. 3 and 4 Another specific exemplary embodiment of the invention is illustrated with reference to FIGS. 3 and 4 in connection with Internet telephony (VoIP, “Voice over Internet Protocol”).
• VoIP Internet telephony
• the communication agent sof follows him when prompted for the new terminal PAL.
• a special sequence of events must occur so that the communication is not interrupted during this migration of the agent until the initialization routines have expired.
• the agent sof copies itself to the new PAL device and takes all necessary steps (searching for audio and video devices, such as a sound card, camera, etc., testing the devices found, preparing and occupying the communication ports such as SIP or RTP ports) so that the signaling can be switched.
• the original agent remains on the first terminal PEC until this has been successfully done and maintains the connection with the remote terminal CLI.
• the desktop computer PEC is no longer involved in the communication; this now runs directly from the handheld computer PAL to the remote terminal CLI, as if communication had been started directly between the two terminals PAL, CLI.
• the signaling of the “new” agent with the corresponding software of the remote station CLI takes place again, for example, via the SIP protocol, and the subsequent transmission of data as part of the communication then takes place, for example, via the RTP - Protocol as explained above instead.
