Motorola Solutions has filed a patent for a converged communication device that operates in multiple modes with varying levels of security. The device includes two subsystems, each with its own processor and communication interface. The first subsystem determines the last operation mode and controls the first communication interface based on the network type and last operation mode. The second subsystem also determines the last operation mode and controls the second communication interface accordingly.

Converged communication device with multiple operation modes and security
A recently filed patent (Publication Number: US20230315915A1) describes a converged communication device that includes two subsystems. The first subsystem consists of an electronic processor and a communication interface, while the second subsystem includes a separate electronic processor and communication interface.
During the startup sequence of the first subsystem, the electronic processor determines the last operation mode and checks if a subscriber identity module (SIM) is installed in the device. If a SIM is detected, the processor determines the network type associated with the SIM and controls the communication interface accordingly. If no SIM is detected, the communication interface is instructed not to communicate wirelessly.
The second subsystem's electronic processor also determines the last operation mode of the first subsystem during its startup sequence and controls its communication interface based on this information.
In one embodiment, if the last operation mode of the first subsystem was a secure mode and the network type is private, the first electronic processor initiates a boot-up sequence for a secure data partition and enables wireless communication with a private network. The second electronic processor controls the second communication interface to communicate wirelessly with a second private communication network and establishes a secure inter-processor communication link with the first subsystem.
Alternatively, if the last operation mode of the first subsystem was a non-secure mode and either no SIM is installed or the network type is public, the first electronic processor initiates a boot-up sequence for a non-secure data partition and enables wireless communication with a public network. The second electronic processor does not allow wireless communication and establishes a secure inter-processor communication link with the first subsystem.
The patent also describes various scenarios where the first electronic processor retrieves a user boot mode selection from memory and controls the communication interface based on this selection, the network type, and the last operation mode. The user boot mode selection can be either manual or automatic.
Overall, this patent describes a converged communication device with two subsystems that can adapt their communication interfaces based on the last operation mode, the presence of a SIM, and the network type. This technology allows for flexible and secure communication options for the device.
