Innovation Solution
A master-slave Bluetooth mobile communication system comprising a host device and an extension device, where the host device logs into a primary network domain and the extension device into a secondary domain, forming an information channel to enable flexible network domain switching and reduce electromagnetic wave exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual mode cellular phone is used to access two network domains, then the user can log in to multiple network domains, but the amount of electromagnetic waves increases significantly
Solution Approach 1:
The patent divides the cellular phone functionality into two separate devices: a host device for primary network domain access and an extension device for secondary network domain access. This segmentation allows each device to operate independently with its own communication module, enabling multi-network domain access while reducing electromagnetic wave emission compared to a traditional dual-mode phone where both modes operate simultaneously.
Solution Approach 2:
The patent introduces a Bluetooth module as an intermediary communication mechanism between the host device and extension device. The Bluetooth module enables wireless communication and data transfer between the two devices, allowing the extension device to function as an accessory to the host device while maintaining separate network domain access capabilities.
2Adaptability or versatility
If a dual mode cellular phone is used to access two network domains, then the user can log in to multiple network domains, but the device complexity increases
Solution Approach 1:
The patent segments the cellular phone into a host device and an extension device, where the extension device is a simpler accessory that connects to the host device via Bluetooth. This segmentation reduces the complexity of the overall system compared to integrating multiple communication modes within a single device, as the extension device only needs to handle secondary network domain access while the host device manages primary access.
Solution Approach 2:
The host device serves multiple functions: it provides primary network domain access, communicates with the extension device via Bluetooth, and coordinates secondary network domain access. This multi-functionality in the host device reduces the need for separate dedicated components, thereby reducing overall device complexity while maintaining versatility.
3Adaptability or versatility
If a dual mode cellular phone is used to access two network domains, then the user can log in to multiple network domains, but the convenience of switching between network accounts is reduced
Solution Approach 1:
The patent implements dynamic network domain access through the extension device, which can be activated or deactivated based on user needs. The extension device communicates with the host device via Bluetooth, allowing dynamic switching between network domains without requiring physical device changes. This dynamic configuration improves ease of operation compared to fixed dual-mode phones.
Solution Approach 2:
The extension device acts as a copy or accessory to the host device, replicating the cellular phone functionality for secondary network domain access. This copying approach allows users to switch between network accounts by simply activating or deactivating the extension device, improving convenience compared to managing multiple physical phones or complex dual-mode configurations.

AI summary
A master-slave mobile communication system includes a host device and an extension device. The host device includes a call module, a first BLUETOOTH® module and a first communication module. The extension device includes a second BLUETOOTH® module and a second communication module. The first and second communication modules log in to a first and a second network domain respectively. The first and second BLUETOOTH® modules provide an information channel between the host device and the extension device to transmit a data. The extension device informs the host device a login data of the second network domain. The host device communicates with a remote device through the first network domain or the information channel and the second network domain that the extension device logs into. Therefore, in a specific range, the host device uses functions of the extension device and a BLUETOOTH® technology to log in to two network domains.
