Remote wake-up system, WWAM module and terminal

A remote wake-up system comprising:

• a terminal;
• a WWAN module configured to receive and/or send information in a wireless manner;
• and
• a security control module configured to perform a security validation on the information received by the WWAN module when the terminal is in a sleep state, and to generate, in the case of a positive the security validation, a wake-up signal and send the wake-up signal to the terminal in order to wake it up;
• wherein the terminal is configured to communicate with the WWAN module, and the security control module is implemented within the terminal,
• the security control module comprises a microprogram controller, and a communication interface controller connected to the microprogram controller and the terminal,
• wherein the communication interface controller is configured to receive the information received by the WWAN module via the terminal, and send the information to the microprogram controller,
• the microprogram controller is configured to perform security validation on information received from the communication interface controller according to stored security validation information, and to generate and send the wake-up signal to the terminal via the communication interface controller;
• and
• the microprogram controller is further configured to send, when the terminal is in a power-off state or the sleep state, a first control signal to the communication interface controller to control it to be in a work state, and to send, when the terminal is in a power-on state, a second control signal to the communication interface controller to control it to be in an off state,
• wherein the terminal comprises a power module configured to supply power to the security control module when the terminal is in the power-off state or the sleep state, wherein the power module comprises a voltage converter and a spare voltage converter, the voltage converter being configured to supply the security control module when terminal is in the power-off state or the sleep state, and the spare voltage converter being configured to supply the security control module when the terminal is in a power-on state.

A terminal, comprising:

• a communication interface unit configured to communicate with a WWAN module;
• a security control module configured to perform a security validation on information received by the WWAN module when the terminal is in a sleep state;
• and
• a power module configured to supply power to the security control module and the communication interface unit;
• wherein the security control module is further configured to generate, in the case of a positive the security validation, a wake-up signal and sending the wake-up signal to the terminal in order to wake it up;
• the security control module comprises a microprogram controller, and a communication interface controller connected to the microprogram controller and the communication interface unit;
• wherein the communication interface controller is configured to receive the information received by the WWAN module via the communication interface unit, and send the information to the microprogram controller,
• the microprogram controller is configured to perform security validation on information received from the communication interface controller according to stored security validation information, and to generate and send the wake-up signal to the terminal via the communication interface controller and the communication interface unit;
• and
• the microprogram controller is further configured to send, when the terminal is in a power-off state or the sleep state, a first control signal to the communication interface controller to control it to be in a work state, and to send, when the terminal is in a power-on state, a second control signal to the communication interface controller to control it to be in an off state;
• wherein the terminal comprises a power module capable of supplying power to the security control module when the terminal is in the power-off state or the sleep state, wherein the power module comprises a voltage converter and a spare voltage converter, the voltage converter being used in supplying the security control module when terminal is in the power-off state or the sleep state, and the spare voltage converter being used in supplying the security control module when the terminal is in the power-on state.
