Existing communication systems face challenges in seamlessly switching between mobile and car telephones, leading to issues like data loss and incomplete functionality when switching devices, and difficulties in simultaneous radio part deactivation, especially in restricted areas.
Innovation Solution
The system employs a communication device with a special memory area for storing individual information from the first device and comparator means to manage data transfer and access, ensuring seamless switching, data consistency, and simultaneous radio part deactivation by using logical communication devices and maintaining a data link for information transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SIM information and connection parameters are transferred between radiotelephones, then connection switching is enabled, but data loss and incomplete functionality occur during switching
Solution Approach 1:
The memory structure is segmented into different areas: a first memory area for individual information (SIM data, connection parameters) and a second memory area for other data. This segmentation allows selective transfer and protection of critical communication data during device switching, preventing data loss while enabling connection transfer.
Solution Approach 2:
The system performs preliminary actions by establishing a data link between the radiotelephones before actual connection switching occurs. Individual information is transferred and validated in advance, ensuring data consistency is maintained before the switch, thus preventing incomplete functionality during the transition.
2Ease of operation
If radiotelephones are connected via data link for information transfer, then seamless switching is achieved, but simultaneous radio part deactivation becomes difficult in restricted areas
Solution Approach 1:
The control units of both radiotelephones are merged into a coordinated control system that manages the data link and radio parts simultaneously. When switching occurs, both control units cooperate to deactivate their radio parts at the same time through the established data link, enabling seamless switching while maintaining compliance in restricted areas.
Solution Approach 2:
The system implements feedback mechanisms where the control unit monitors the status of both radiotelephones during switching. The data link provides real-time feedback on connection status and radio part states, allowing the control unit to coordinate deactivation precisely and ensure simultaneous shutdown when required by restricted area regulations.
3Reliability
If individual information is stored in memory during switching, then data consistency is maintained, but access to information from disconnected devices is lost
Solution Approach 1:
The system creates copies of individual information (SIM data, connection parameters) in the memory of both radiotelephones during the switching process. This copying ensures that the information remains accessible even when devices are disconnected, while the control unit validates that the copied data maintains consistency with the source device.

AI summary
The present invention relates to communication system comprising first and second communication devices (11,12) each capable of communicating with a telecommunications network (10), and both being connectable to each other by a data link (17) for information transfer and to a method for operating the same. The first communication device (11) contains individual information, and the second communication device (12) comprises a special memory area (21) for storing individual information acquired from the first communication device (11). To enable an improved and facilitated usage of the system comparator means (22) for comparing the individual information contained in the first communication device (11) with that stored in the special memory area (21) of the second communication (12) device are provided. Therefore, only changes of the individual information of the first communication device (11) are stored in the second communication device (12) after comparing the individual information from the first communication device (11) stored in the second communication device (12) with the individual information in the first communication device (11) when the first communication device (11) is connected again to the second communication device (12).
