DETAILED DESCRIPTION

[0052] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, not all of the embodiments. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present application.

[0053] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0054] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example: a component or device including one or more parts is not limited to the one or more parts listed, but optionally includes one or more parts that are not listed but inherent to the exemplified product, or one or more parts that it should have based on the described function.

[0055] The working states of the terminal device 1000 include shutdown, standby and online states. The shutdown state means that the terminal device 1000 is disconnected from the network, but the terminal is not completely powered off after shutdown, and a small part of the modules work at low power consumption, similar to hibernation.

[0056] The standby state (idle mode) means that the terminal device 1000 has not established a service connection with the network, but maintains awareness of the network, has low power consumption, saves resources, and is similar to a person's sleep state.

[0057] The online state means that the terminal device 1000 establishes a service connection with the network, which consumes a lot of power and is similar to the awake state of a person.

[0058] The terminal device 1000 also includes a sleep state and a wake-up state in the standby state.

[0059] See also Figure 1 In the standby state, the terminal device 1000 receives a wake-up signal from the network side device 2000 (such as a base station, etc.) at intervals. In this way, the standby time period of the terminal device 1000 includes a sleep period and a wake-up period that appear in sequence. Further, the stage when the terminal device 1000 interacts with the base station for the last time to confirm the sleep cell at this time is defined as the pre-sleep period, and the standby stage of the terminal device 1000 includes at least one pre-sleep period, several sleep periods, and several wake-up periods.

[0060] After the terminal device 1000 enters the idle mode (sleep mode), the terminal device 1000 should periodically turn on the receiver (the RF transceiver module of the terminal device 1000) to receive paging messages according to the DRX cycle and the specific paging opportunity (PO) of the terminal device 1000, so as to keep the terminal device 1000 in touch with the network side device 2000, ensure that it can quickly respond to the network side device 2000 service when necessary, and improve the contact response speed. However, the above process requires the receiver (the RF transceiver module of the terminal device 1000) in the terminal device 1000 to be frequently awakened and processed to receive network signals, and the awakening process of the receiver of the terminal device 1000 brings certain power consumption.

[0061] See also Figure 2 , a radio frequency system 100 is provided in the first embodiment of the application. The radio frequency system 100 is applied to a terminal device 1000.

[0062] The terminal device 1000 includes but is not limited to a mobile phone, a tablet computer, a laptop computer, a computer, a wearable device, a drone, a robot, a digital camera, and other devices with communication functions. The present application embodiment is described by taking a mobile phone as an example, and other electronic devices can refer to this embodiment.

[0063] See also Figure 3 The terminal device 1000 provided in the present application includes the aforementioned radio frequency system 100. The terminal device 1000 includes a circuit board 600, and at least part of the radio frequency system 100 may be disposed on the circuit board 600.

[0064] See also Figure 2 and Figure 3 The RF system 100 includes a RF transceiver module 60 , a RF front-end circuit 20 and a monitoring module 10 .

[0065] The RF transceiver module 60 may be in the form of a circuit disposed on the circuit board 600, or an independently packaged chip, or a chip packaged together with other circuits, etc. The RF transceiver module 60 may also be called a transceiver, a RF transceiver chip, etc.

[0066] See also Figure 2 and Figure 3 , the RF front-end circuit 20 is electrically connected to the RF transceiver module 60. The RF transceiver module 60 is used to transmit and receive wireless signals via the RF front-end circuit 20. In other words, the RF front-end circuit 20 is used to receive RF signals from the RF transceiver module 60, and RF signals can also be called transceiver signals, wireless signals, etc.

[0067] Specifically, the RF front-end circuit 20 includes but is not limited to a RF link between the RF transceiver module 60 and the antenna radiator 30. The RF front-end circuit 20 may also be referred to as a RF front-end module (RFFE). The RF front-end circuit 20 includes but is not limited to a power amplifier (PA), an antenna switch (Switch), a filter (Filter), a duplexer (Duplexer) and a low noise amplifier (LNA), etc. The RF front-end circuit 20 includes at least one of a signal transmission channel 21 and a signal receiving channel 22, ensuring the effective reception and transmission of wireless signals. Among them, the power amplifier is used to enhance the RF signal of the transmission channel. The antenna switch is used to switch the RF signal between the receiving and transmitting states, and to switch between different frequency bands. The filter is used to filter out signals in a specific frequency band and filter out other unnecessary frequency band signals. The duplexer is used to ensure the isolation of the transmission and reception signals so that both can work normally when the antenna radiator is shared. The low noise amplifier is used to amplify the RF signal of the receiving channel.

[0068] The RF front-end circuit 20 may be in the form of a circuit disposed on the circuit board 600 , or an independently packaged chip, or a chip integrated and packaged together with other circuits.

[0069] See also Figure 4 In this application, a radio frequency front-end circuit 20 includes a signal transmitting channel 21 and a signal receiving channel 22 as an example.

[0070] For further information, see Figure 4 The RF system 100 also includes an antenna radiator 30 , and the RF front-end circuit 20 is electrically connected to the antenna radiator 30 .

[0071] Exemplarily, the RF transceiver module 60 is electrically connected to the RF front-end circuit 20 to send the modulated RF signal to the RF front-end circuit 20, which is then transmitted through the antenna radiator 30 after being amplified and processed by the RF front-end circuit 20, or the RF transceiver module 60 receives the RF signal through the antenna radiator 30 and filtered by the RF front-end circuit 20.

[0072] The supervision module 10 is coupled to the RF front-end circuit 20. Specifically, the supervision module 10 is coupled to the signal transmission channel 21 and / or the signal receiving channel 22 of the RF front-end circuit 20.

[0073] Specifically, the coupling connection includes but is not limited to direct electrical connection or coupling through a device. Further, the supervision module 10 is coupled with the circuit portion of the RF front-end circuit 20 close to the antenna radiator 30, so that the supervision module 10 can receive network signals when the signal receiving channel 22 of the RF front-end circuit 20 is closed.

[0074] Please refer to Figure 4 The form of the supervision module 10 includes but is not limited to a circuit arranged on the circuit board 600, or an independently packaged chip, or a chip integrated and packaged together with other circuits.

[0075] The supervision module 10 is configured to monitor the first network signal from the network side device 2000. The first network signal includes but is not limited to a wake-up signal or a paging signal. Optionally, at a certain stage, the RF front-end circuit 20 receives the first network signal from the network side device 2000, and the supervision module 10 acquires the characteristic parameters of the first network signal by collecting the signal in the receiving channel of the RF front-end circuit 20. The characteristic parameters include but are not limited to the signal strength of the first network signal, the frequency of receiving the signal, the signal instruction content, etc. The network side device 2000 includes but is not limited to a base station, etc.

[0076] For the convenience of description, the signal obtained by the monitoring module 10 monitoring the first network signal is defined as a coupling signal.

[0077] The supervision module 10 is configured to determine, according to the characteristic parameters of the first network signal, that one of the RF front-end circuit 20 and the RF transceiver module 60 is in sleep mode, and the other is in wake-up mode, or that both the RF front-end circuit 20 and the RF transceiver module 60 are in sleep mode or both are in wake-up mode. In this embodiment, the supervision module 10 is configured to determine, according to the characteristic parameters of the first network signal satisfying the first condition, that both the RF front-end circuit 20 and the RF transceiver module 60 are in sleep mode.

[0078] In a second optional implementation, the supervision module 10 is configured to determine that both the RF front-end circuit 20 and the RF transceiver module 60 are in the wake-up mode according to whether the characteristic parameters of the first network signal satisfy a second condition.

[0079] In a third optional implementation, the supervision module 10 is configured to determine that the RF front-end circuit 20 is in the sleep mode according to whether the characteristic parameter of the first network signal satisfies a third condition. The RF transceiver module 60 is in the wake-up mode.

[0080] In a fourth optional implementation, the supervision module 10 is configured to determine that the RF front-end circuit 20 is in the awakening mode according to whether the characteristic parameter of the first network signal satisfies a fourth condition. The RF transceiver module 60 is in the sleep mode.

[0081] The first condition, the second condition, the third condition and the fourth condition will be described in detail later.

[0082] The following takes the case where the RF front-end circuit 20 and the RF transceiver module 60 are both in the sleep mode as an example.

[0083] Optionally, the signal receiving channel 22 of the RF front-end circuit 20 is in a closed state in the sleep mode. Correspondingly, in the sleep mode, part of the control module in the RF transceiver module 60 for controlling the RF front-end circuit 20 to receive signals is also in a closed state. At this time, the RF front-end circuit 20 no longer receives and transmits wireless signals.

[0084] Further optionally, the signal receiving channel 22 and the signal transmitting channel 21 of the RF front-end circuit 20 are both in a closed state in the sleep mode. Correspondingly, in the sleep mode, part of the control module in the RF transceiver module 60 for controlling the RF front-end circuit 20 to receive and transmit signals is also in a closed state.

[0085] The following takes the case where the RF front-end circuit 20 and the RF transceiver module 60 are both in the awake mode as an example.

[0086] The signal transmission channel 21 and the signal receiving channel 22 of the RF front-end circuit 20 are in working state in the wake-up mode. Correspondingly, in the wake-up mode, part of the control module in the RF transceiver module 60 for controlling the RF front-end circuit 20 to receive and transmit signals is also in working state. At this time, the RF front-end circuit 20 can transmit an inquiry signal to the network side device 2000 at least once under the control signal of the RF transceiver module 60, and receive a reply signal from the network side device 2000 at least once to determine whether the network side device 2000 has been changed.

[0087] The RF system 100 provided in this embodiment includes a RF transceiver module 60, a RF front-end circuit 20, and a supervision module 10. The RF front-end circuit 20 is electrically connected to the RF transceiver module 60, and the RF transceiver module 60 is used to transmit and receive wireless signals through the RF front-end circuit 20; the supervision module 10 is coupled to the RF front-end circuit 20, and the supervision module 10 is configured to monitor a first network signal from a network side device 2000, and determine, based on characteristic parameters of the first network signal, whether one of the RF front-end circuit 20 and the RF transceiver module 60 is in sleep mode, and the other is in wake-up mode, or whether both the RF front-end circuit 20 and the RF transceiver module 60 are in sleep mode. Or both are in wake-up mode, the signal receiving channel 22 of the RF front-end circuit 20 is in a closed state in the sleep mode, and the signal transmitting channel 21 and the signal receiving channel 22 of the RF front-end circuit 20 are in a working state in the wake-up mode; in this embodiment, the sleep mode or wake-up mode of the RF front-end circuit 20 and the RF transceiver chip is monitored and identified through the supervision module 10, and the RF transceiver chip and the processor do not need to maintain a certain power consumption state to realize the monitoring of the sleep mode or the wake-up mode. Since the supervision module 10 has fewer devices and consumes less power than the RF transceiver chip and the processor, it can reduce more energy loss, which is conducive to realizing a low-power RF architecture.

[0088] For example, see Figure 4 The supervision module 10 includes an identification module 11, a calculation module 12 and an instruction conversion module 13.

[0089] The identification module 11, the calculation module 12, and the instruction conversion module 13 may be in the form of a circuit disposed on the circuit board 600, or an independently packaged chip, or a chip integrated and packaged together with other circuits.

[0090] Among them, the identification module 11 is configured to obtain characteristic parameters of the RF signal transmitted by the RF front-end circuit 20. When the RF front-end circuit 20 receives the first network signal from the network side device 2000, the identification module 11 can obtain the signal strength of the first network signal, and determine whether the signal strength of the first network signal changes. If the signal strength of the first network signal is basically unchanged, it means that the position of the terminal device 1000 relative to the network side device 2000 is basically unchanged. At this time, the terminal device 1000 is in a standby state anchored with the network side device 2000 and "stationary". If the signal strength of the first network signal changes greatly, it means that the position of the terminal device 1000 relative to the network side device 2000 changes greatly. At this time, the terminal device 1000 is in a standby state anchored with the network side device 2000 and "moving". When the terminal device 1000 is in a "stationary" standby state, the RF transceiver module 60 and the RF front-end circuit 20 can maintain the first state feedback signal. When the terminal device 1000 is in the "mobile" standby state, the RF transceiver module 60 and the RF front-end circuit 20 need to maintain the second state feedback signal to determine whether the terminal device 1000 moves out of the coverage area of ​​the anchor network side device 2000.

[0091] The above process is further described below.

[0092] Optionally, the identification module 11 includes a first signal input terminal. The first signal input terminal is electrically connected to the RF front-end circuit 20 to obtain characteristic parameters of the RF signal transmitted by the RF front-end circuit 20. The electrical connection between the first signal input terminal and the RF front-end circuit 20 in the present application includes but is not limited to a direct electrical connection or a capacitive coupling electrical connection.

[0093] See also Figure 4 , the identification module 11 is electrically connected to the calculation module 12.

[0094] The identification module 11 is configured to monitor and compare characteristic parameters of the first network signal with preset parameters.

[0095] The characteristic parameters include but are not limited to the signal strength of the first network signal, the signal frequency of the first network signal, or the instruction content of the first network signal, etc. Correspondingly, the preset parameters include but are not limited to the preset strength, preset signal frequency, or preset instruction content pre-stored in the memory of the terminal device 1000.

[0096] The preset strength includes but is not limited to the signal strength of the signal receiving channel 22 of the RF front-end circuit 20 receiving the signal from the network side device 2000 at the last time (or the previous times). The supervision module 10 can analyze the coupling signal (the signal obtained by monitoring the first network signal) to obtain the strength of the first network signal, and use the strength as the preset strength.

[0097] The preset signal frequency includes but is not limited to the signal frequency of the first network signal (such as a wake-up signal) received by the terminal device 1000 from the network device 2000 after the last service interaction between the terminal device 1000 and the network device 2000 in the online state. The supervision module 10 can parse the coupling signal (the signal obtained by monitoring the first network signal) to obtain the signal frequency of the first network signal, and use the signal frequency as the preset signal frequency.

[0098] Among them, the preset instruction content includes but is not limited to the preset instruction content of the first network signal (such as a wake-up signal) received by the terminal device 1000 from the network side device 2000 after the last business interaction between the terminal device 1000 and the network side device 2000 in the online state. The supervision module 10 can parse the coupling signal (the signal obtained by monitoring the first network signal) to obtain the preset instruction content of the first network signal, and use the preset instruction content as the preset instruction content. Of course, in other embodiments, the preset instruction content can also be a transmission instruction that does not include the scheduling RF transceiver module 60 to transmit a wireless signal in the first network signal. In other words, the position corresponding to the transmission instruction in the preset instruction content is empty.

[0099] See also Figure 4 , the calculation module 12 is electrically connected to the instruction conversion module 13.

[0100] The calculation module 12 is configured to control the output instruction of the instruction conversion module 13 according to the comparison result. The comparison result is a comparison result of comparing the characteristic parameter of the first network signal with a preset parameter.

[0101] For further example, the identification module 11 determines that the difference between the strength of the first network signal and the preset strength is less than the first strength value. The identification module 11 sends the comparison result to the calculation module 12, and the calculation module 12 determines that the difference between the strength of the first network signal and the preset strength is less than the first strength value, and the control instruction conversion module 13 outputs a first control instruction. The first control instruction is used to indicate that the RF front-end circuit 20 and / or the RF transceiver module 60 is in sleep mode.

[0102] In a first optional implementation, the instruction conversion module 13 outputs a first control instruction to the RF front-end circuit 20 , where the first control instruction is used to control the RF front-end circuit 20 to be in a sleep mode.

[0103] In a second optional implementation, the instruction conversion module 13 outputs a first control instruction to the RF transceiver module 60 , where the first control instruction is used to control the RF transceiver module 60 to be in a sleep mode.

[0104] In a third optional implementation, the instruction conversion module 13 outputs the first control instruction to the processor, and the processor is used to control the RF transceiver module 60 to be in sleep mode under the action of the first control instruction, and directly control the RF front-end circuit 20 to be in sleep mode; or indirectly control the RF front-end circuit 20 to be in sleep mode through the RF transceiver module 60.

[0105] In other implementations, the three control modes of the first control instruction may be combined with each other.

[0106] For further example, the identification module 11 determines that the difference between the strength of the first network signal and the preset strength is greater than or equal to the first strength value. The identification module 11 sends the comparison result to the calculation module 12, and the calculation module 12 determines that the difference between the strength of the first network signal and the preset strength is greater than or equal to the first strength value, and the control instruction conversion module 13 outputs a second control instruction. The second control instruction is used to indicate that the RF front-end circuit 20 and the RF transceiver module 60 are in the wake-up mode.

[0107] In a first optional implementation, the instruction conversion module 13 outputs the second control instruction to the RF front-end circuit 20, and the second control instruction is used to control the RF front-end circuit 20 to be in the wake-up mode. The instruction conversion module 13 outputs the second control instruction to the RF transceiver module 60, and the second control instruction is used to control the RF transceiver module 60 to be in the wake-up mode.

[0108] In a second optional implementation, the instruction conversion module 13 outputs the second control instruction to the processor, and the processor is used to control the RF transceiver module 60 to be in the wake-up mode under the action of the second control instruction, and directly control the RF front-end circuit 20 to be in the wake-up mode; or indirectly control the RF front-end circuit 20 to be in the wake-up mode through the RF transceiver module 60.

[0109] This embodiment uses the first network signal from the network side device 2000 received by the signal receiving channel 22 of the RF front-end circuit 20 of the monitoring module, collects the characteristic parameters in the first network signal, and compares the characteristic parameters with the preset parameters. It can determine whether the terminal device 1000 is in the standby "stationary" state or the standby "mobile" state. If the terminal device 1000 is in the standby "stationary" state, at this time, the terminal device 1000 basically has no risk of moving out of the coverage area of ​​the anchor network side device 2000, so the RF front-end circuit 20 can still be in the sleep mode; if the terminal device 1000 is in the standby "mobile" state, at this time, the terminal device 1000 has the risk of moving out of the coverage area of ​​the anchor network side device 2000, so the RF front-end circuit 20 can be in the wake-up mode. The RF front-end circuit 20 can send an inquiry signal at least once in the wake-up mode to determine whether the anchor network side device 2000 has changed. Compared with the case where the terminal device 1000 is in the standby "static" state, the RF front-end circuit 20 and the RF transceiver module 60 are also in the wake-up mode, in the present embodiment, it is possible to achieve that when the terminal device 1000 is in the standby "static" state, the RF front-end circuit 20 and the RF transceiver module 60 are in the sleep mode. In the sleep mode, the signal receiving channel 22 of the RF front-end circuit 20 is closed, the signal transmitting channel 21 is closed, and the related control modules and data processing modules of the RF transceiver module 60 can also be closed, which can save a lot of energy and further reduce the power consumption of the terminal device 1000.

[0110] For example, see Figure 5 The RF front-end circuit 20 includes a coupler 23. One end of the monitoring module 10 is electrically connected to the coupler 23.

[0111] The coupler 23 includes power distribution components. The coupler 23 divides one microwave power into several paths in proportion in the microwave system, and then extracts a small portion of the signal from the wireless signal trunk channel. The coupler 23 includes but is not limited to a directional coupler 23, a power divider, and a microwave branching device.

[0112] In an alternative embodiment, see Figure 5 , the RF front-end circuit 20 includes a coupler 23. In other words, the coupler 23 is built into the RF front-end circuit 20 chip and has an external output port.

[0113] The coupler 23 is electrically connected to the identification module 11. Further, an output port of the coupler 23 is electrically connected to the identification module 11. The coupler 23 is configured to couple the radio frequency signal in the radio frequency front-end circuit 20 to the identification module 11.

[0114] In another optional implementation, the monitoring module 10 further includes a coupler 23. In other words, the coupler 23 is built outside the RF front-end circuit 20 chip.

[0115] The coupler 23 is electrically connected to the identification module 11 and the RF front-end circuit 20. Further, an input end of the coupler 23 is electrically connected to the RF front-end circuit 20, and an output end of the coupler 23 is electrically connected to the identification module 11. The coupler 23 is configured to couple the RF signal in the RF front-end circuit 20 to the identification module 11.

[0116] The specific structure of the monitoring module 10 is described below with reference to the accompanying drawings.

[0117] Further optionally, the identification module 11 includes but is not limited to a power detection module. The input power of the power amplifier in the signal receiving channel 22 of the RF front end is detected and amplified, and finally the input power is obtained. The instruction conversion module 13 is used to parse the input MIPI instruction (such as a control instruction indicating wake-up) and output a new instruction (such as a control instruction indicating sleep) or pass the input instruction (such as a control instruction indicating wake-up). The calculation module 12 is used to control the obtained MIPI instruction (such as a control instruction indicating wake-up), calculate and process the obtained power, etc., and finally control. The instruction conversion module 13 outputs the instruction that needs to be modified (such as a control instruction indicating wake-up).

[0118] See also Figure 6 The identification module 11 also includes but is not limited to a feedback gain circuit. The identification module 11 includes a detector 111 and a low noise amplifier 112 .

[0119] The detector 111 is electrically connected to the coupler 23 in the RF front-end circuit 20. The detector 111 is configured to obtain a detection signal from the RF signal in the transmission path of the RF front-end circuit 20. The detector 111 is also called a phase detector or a demodulator, and is used to extract the original information signal from the modulated signal.

[0120] The low noise amplifier 112 is electrically connected to the detector 111 and the calculation module 12 . The low noise amplifier 112 is configured to amplify the detection signal, obtain the characteristic parameter from the amplified detection signal, and send the characteristic parameter to the calculation module 12 .

[0121] The feedback gain circuit is used to monitor the characteristics of the output signal, including power, spectrum, error vector magnitude (EVM), etc., to ensure that the transmitted signal meets the expected standards and specifications; through feedback, the nonlinear distortion of the RF power amplifier (PA) can be detected and compensated to improve the linearity of the overall system; the pre-distortion algorithm can also be adjusted according to the feedback signal to compensate for the nonlinear distortion; by monitoring the feedback signal, the transmit power can be adjusted in real time to keep it within the specified range.

[0122] The supervision module 10 proposed in this embodiment can form a closed-loop feedback loop identification module. The supervision module 10 can couple power from the coupler 23 of the RF front-end circuit 20 to the identification module 11. The identification module 11 can parse the carried power to obtain characteristic parameters such as signal strength, signal frequency, and instruction content and provide them to the calculation module 12 of the supervision module 10 to realize state identification; when the state of the terminal device 1000 is identified as standby "stationary", the parameters to be adjusted are directly converted into corresponding instructions (such as control instructions indicating sleep) through the instruction conversion module 13 of the MIPI instruction (such as a control instruction indicating wake-up) and given to the RF front-end circuit 20 for direct adjustment, thereby realizing efficient and fast self-closed-loop processing. This process does not require instruction conversion through the processor, RF transceiver module 60, etc., which can greatly save the time from state identification to instruction conversion and greatly reduce power consumption.

[0123] Exemplarily, the supervision module 10 is further configured to operate in a takeover mode when the RF front-end circuit 20 is in the sleep mode. In the takeover mode, the supervision module 10 receives and processes a first network signal from the network-side device 2000 .

[0124] It should be noted that in the monitoring mode, the supervision module 10 receives the first network signal from the network side device 2000 by monitoring the RF front-end circuit 20, and the signal received by the supervision module 10 is a coupling signal. In the takeover mode, the supervision module 10 can receive the first network signal.

[0125] When the terminal device 1000 is in standby "stationary" state, the supervision module 10 can receive a periodic first network signal and process the periodic first network signal, so that although the terminal device 1000 has not established a service connection with the network side device 2000, it always maintains network awareness of the anchored network side device 2000, so that the anchored network side device 2000 knows the terminal device 1000 and can quickly find the terminal device 1000 when the terminal device 1000 is called, thereby improving the response speed.

[0126] In this embodiment, the supervision module 10 is in the takeover mode when the RF front-end circuit 20 is in the sleep mode, and further, the RF transceiver module 60 is in the sleep mode. Compared with the RF transceiver module 60 and the RF front-end circuit 20 being both in the wake-up mode, the power consumption of the supervision module 10 in the takeover mode is much less than that of the RF transceiver module 60 and the RF front-end circuit 20 in the wake-up mode due to the relatively few functions and internal components of the supervision module 10, thereby further reducing the power consumption.

[0127] Further optionally, the supervision module 10 is also configured to operate in the monitoring mode when the RF front-end circuit 20 is in the wake-up mode. For example, when the RF front-end circuit 20 and the RF transceiver module 60 are in the wake-up mode, the supervision module 10 operates in the monitoring mode to receive the coupling signal.

[0128] In other embodiments, when the RF front-end circuit 20 and the RF transceiver module 60 are in the sleep mode, the supervision module 10 is also in the monitoring mode, maintaining the monitoring of the characteristic parameters of the first network signal, and when the conditions are met, directly controlling or feeding back to the processor to control the RF front-end circuit 20 and the RF transceiver module 60 to switch to the wake-up mode.

[0129] See also Figure 7 , the RF system 100 further includes a processor 40. The processor 40 includes but is not limited to a processor 40 (AP) in the terminal device 1000. The processor 40 is electrically connected to the supervision module 10 and the RF transceiver module 60.

[0130] The supervision module 10 receives the first network signal from the network side device 2000 via the coupler 23, and generates a first state feedback signal or a second state feedback signal according to the comparison result of the characteristic parameter of the first network signal and the preset parameter. Further, the supervision module 10 sends the generated first state feedback signal or the second state feedback signal to the processor 40.

[0131] Optionally, the mode switching (sleep mode and wake-up mode) of the RF front-end circuit 20 and the RF transceiver module 60 is controlled by the processor 40; or, the mode switching (sleep mode and wake-up mode) of the RF front-end circuit 20 and the RF transceiver module 60 is controlled by the supervision module 10; or, the mode switching (sleep mode and wake-up mode) of the RF transceiver module 60 is controlled by the processor 40, and the mode switching (sleep mode and wake-up mode) of the RF front-end circuit 20 is controlled by the RF transceiver module 60.

[0132] See also Figure 8 and Fig. 9, the processor 40 is configured to control the RF front-end circuit 20 and / or the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal.

[0133] In an optional implementation, the processor 40 is configured to control the RF front-end circuit 20 and the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal; or, the processor 40 is configured to control the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal, and the RF transceiver module 60 sends a sleep instruction to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the sleep mode; or, the processor 40 is configured to control the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal, and the supervision module 10 converts the wake-up instruction sent by the RF transceiver module 60 into a sleep instruction and sends it to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the sleep mode.

[0134] See also Figure 8 and Fig. 9 The processor 40 is configured to indicate that the RF front-end circuit 20 and the RF transceiver module 60 are in the wake-up mode according to the second state feedback signal.

[0135] In an optional implementation, the processor 40 is configured to control the RF front-end circuit 20 and the RF transceiver module 60 to be in the wake-up mode according to the second state feedback signal.

[0136] Among them, the processor 40 is configured to control the RF transceiver module 60 to be in the wake-up mode according to the second state feedback signal, and the RF transceiver module 60 sends a wake-up instruction to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the wake-up mode; or, the processor 40 is configured to control the RF transceiver module 60 to be in the wake-up mode according to the second state feedback signal, and the supervision module 10 transmits the wake-up instruction sent by the RF transceiver module 60 to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the wake-up mode.

[0137] For example, see Figure 8 and Fig. 9 The instruction conversion module 13 is electrically connected to the RF transceiver module 60 and the RF front-end circuit 20. The RF transceiver module 60 sends a first instruction to the instruction conversion module 13.

[0138] The instruction conversion module 13 is configured to transmit the first instruction to the RF front-end circuit 20 or convert it into a second instruction according to the comparison result between the characteristic parameters of the first network signal and the preset parameters. The first instruction is used to control the RF front-end circuit 20 to be in a wake-up mode. The second instruction is used to control the RF front-end circuit 20 to be in a sleep mode.

[0139] Specifically, when the comparison result indicates that the terminal device 1000 is in a standby "static" state, the instruction conversion module 13 converts the first instruction into a second instruction, and sends the second instruction to the RF front-end circuit 20, so that the RF front-end circuit 20 is in sleep mode. The signal sending channel and the signal receiving channel 22 of the RF front-end circuit 20 are closed. Further optionally, the supervision module 10 receives the first network signal, and the supervision module 10 enters the takeover mode. Further optionally, the supervision module 10 sends the first state feedback signal to the processor 40, and the processor 40 shuts down part of the control circuit and the data processing circuit of the RF transceiver module 60 according to the first state feedback signal to reduce the power consumption of the RF transceiver module 60, and further reduce the standby power consumption of the terminal device 1000.

[0140] In other embodiments, see Fig.10 , a first instruction circuit 61 is also electrically connected between the RF transceiver module 60 and the RF front-end circuit 20, and the instruction circuit formed between the RF transceiver module 60, the instruction conversion module 13 and the RF front-end circuit 20 is a second instruction circuit 62. Among them, the first instruction circuit 61 transmits a first instruction, that is, a wake-up instruction. When the supervision module 10 determines that the RF front-end circuit 20 and the RF transceiver module 60 need to be in the wake-up mode, the first instruction circuit 61 is turned on, and the first instruction is transmitted to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the wake-up mode.

[0141] The second instruction line 62 transmits the second instruction, i.e., the sleep instruction. When the supervision module 10 determines that the RF front-end circuit 20 and the RF transceiver module 60 need to be in the sleep mode, the second instruction line 62 is turned on and the second instruction is transmitted to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the sleep mode.

[0142] See also Fig.11 , Example 2 of this application provides a supervision method. Please refer to Figures 1 to 10, the method is applied to the RF system 100 described in any one of the aforementioned embodiments. The RF system 100 is applied to a terminal device 1000. The RF system 100 includes a RF transceiver module 60, a RF front-end circuit 20 and a supervisory module 10. The RF front-end circuit 20 is electrically connected to the RF transceiver module 60. The supervisory module 10 is electrically connected to the RF front-end circuit 20. The method includes but is not limited to the following steps.

[0143] Step S100: the monitoring module 10 monitors a first network signal from the network-side device 2000 .

[0144] Optionally, at a certain stage, the RF front-end circuit 20 receives a first network signal from the network side device 2000, and the supervision module 10 acquires characteristic parameters of the first network signal by collecting signals in the receiving channel of the RF front-end circuit 20. The characteristic parameters include but are not limited to the signal strength of the first network signal, the frequency of receiving the signal, the signal instruction content, etc.

[0145] For the convenience of description, the signal obtained by the monitoring module 10 monitoring the first network signal is defined as a coupling signal.

[0146] Step S200: The supervision module 10 determines, based on the characteristic parameters of the first network signal, that one of the RF front-end circuit 20 and the RF transceiver module 60 is in sleep mode, and the other is in wake-up mode, or that both the RF front-end circuit 20 and the RF transceiver module 60 are in sleep mode or both are in wake-up mode. The signal receiving channel 22 of the RF front-end circuit 20 is in a closed state in the sleep mode. The signal transmitting channel 21 and the signal receiving channel 22 of the RF front-end circuit 20 are in a working state in the wake-up mode.

[0147] In a first optional implementation, the supervision module 10 is configured to determine that both the RF front-end circuit 20 and the RF transceiver module 60 are in sleep mode according to whether characteristic parameters of the first network signal satisfy a first condition.

[0148] In a second optional implementation, the supervision module 10 is configured to determine that both the RF front-end circuit 20 and the RF transceiver module 60 are in the wake-up mode according to whether the characteristic parameters of the first network signal satisfy a second condition.

[0149] In a third optional implementation, the supervision module 10 is configured to determine that the RF front-end circuit 20 is in the sleep mode according to whether the characteristic parameter of the first network signal satisfies a third condition. The RF transceiver module 60 is in the wake-up mode.

[0150] In a fourth optional implementation, the supervision module 10 is configured to determine that the RF front-end circuit 20 is in the awakening mode according to whether the characteristic parameter of the first network signal satisfies a fourth condition. The RF transceiver module 60 is in the sleep mode.

[0151] The following takes the case where the RF front-end circuit 20 and the RF transceiver module 60 are both in the sleep mode as an example.

[0152] Optionally, in the sleep mode, the signal receiving channel 22 of the RF front-end circuit 20 is in a closed state. Correspondingly, in the sleep mode, part of the control module in the RF transceiver module 60 for controlling the RF front-end circuit 20 to receive signals is also in a closed state. At this time, the RF front-end circuit 20 no longer receives and transmits wireless signals.

[0153] Further, optionally, in the sleep mode, the signal receiving channel 22 and the signal transmitting channel 21 of the RF front-end circuit 20 are both in a closed state. Correspondingly, in the sleep mode, part of the control module in the RF transceiver module 60 for controlling the RF front-end circuit 20 to receive and transmit signals is also in a closed state.

[0154] The following takes the case where the RF front-end circuit 20 and the RF transceiver module 60 are both in the awake mode as an example.

[0155] In the wake-up mode, the signal transmission channel 21 and the signal receiving channel 22 of the RF front-end circuit 20 are in working state. Correspondingly, in the wake-up mode, part of the control module in the RF transceiver module 60 for controlling the RF front-end circuit 20 to receive and transmit signals is also in working state. At this time, the RF front-end circuit 20 can transmit an inquiry signal to the network side device 2000 at least once under the control signal of the RF transceiver module 60, and receive a reply signal from the network side device 2000 at least once to determine whether the network side device 2000 has been changed.

[0156] The supervision method provided in this embodiment monitors the first network signal from the network side device 2000 through the supervision module 10, and the supervision module 10 determines that one of the RF front-end circuit 20 and the RF transceiver module 60 is in sleep mode and the other is in wake-up mode according to the characteristic parameters of the first network signal, or the RF front-end circuit 20 and the RF transceiver module 60 are both in sleep mode or both in wake-up mode. In the sleep mode, the signal receiving channel 22 of the RF front-end circuit 20 is in a closed state. In the wake-up mode, the signal transmission channel 21 and the signal receiving channel 22 of the RF front-end circuit 20 are in a working state. In this embodiment, the supervision module 10 monitors and identifies the sleep mode or wake-up mode of the RF front-end circuit 20 and the RF transceiver chip, and the RF transceiver chip and the processor 40 do not need to maintain a certain power consumption state to realize the monitoring of the sleep mode or wake-up mode. Since the supervision module 10 has fewer devices and less power consumption than the RF transceiver chip and the processor 40, it can reduce more energy loss and reduce power consumption.

[0157] For example, please refer to Figures 1 to 10 , the supervision module 10 includes an identification module 11, a calculation module 12 and an instruction conversion module 13. The identification module 11 is electrically connected to the calculation module 12. The calculation module 12 is electrically connected to the instruction conversion module 13. The supervision module 10 in this embodiment can refer to the supervision module 10 in the first embodiment.

[0158] See also Fig.12 , step S200: the supervision module 10 determines, according to the characteristic parameters of the first network signal, that one of the RF front-end circuit 20 and the RF transceiver module 60 is in sleep mode, and the other is in wake-up mode, or that both the RF front-end circuit 20 and the RF transceiver module 60 are in sleep mode or both are in wake-up mode, including but not limited to the following steps.

[0159] Step S210: the identification module 11 compares the characteristic parameters of the first network signal with preset parameters.

[0160] The characteristic parameters include but are not limited to the signal strength of the first network signal, the signal frequency of the first network signal, or the instruction content of the first network signal, etc. Correspondingly, the preset parameters include but are not limited to the preset strength, preset signal frequency, or preset instruction content pre-stored in the memory of the terminal device 1000.

[0161] The preset strength includes but is not limited to the signal strength of the signal receiving channel 22 of the RF front-end circuit 20 receiving the signal from the network side device 2000 at the last time (or the previous times). The supervision module 10 can analyze the coupling signal (the signal obtained by monitoring the first network signal) to obtain the strength of the first network signal, and use the strength as the preset strength.

[0162] The preset signal frequency includes but is not limited to the signal frequency of the first network signal (such as a wake-up signal) received by the terminal device 1000 from the network device 2000 after the last service interaction between the terminal device 1000 and the network device 2000 in the online state. The supervision module 10 can parse the coupling signal (the signal obtained by monitoring the first network signal) to obtain the signal frequency of the first network signal, and use the signal frequency as the preset signal frequency.

[0163] Among them, the preset instruction content includes but is not limited to the preset instruction content of the first network signal (such as a wake-up signal) received by the terminal device 1000 from the network side device 2000 after the last business interaction between the terminal device 1000 and the network side device 2000 in the online state. The supervision module 10 can parse the coupling signal (the signal obtained by monitoring the first network signal) to obtain the preset instruction content of the first network signal, and use the preset instruction content as the preset instruction content. Of course, in other embodiments, the preset instruction content can also be a transmission instruction that does not include the scheduling RF transceiver module 60 to transmit a wireless signal in the first network signal. In other words, the position corresponding to the transmission instruction in the preset instruction content is empty.

[0164] Step S220: The identification module 11 determines that the RF front-end circuit 20 and / or the RF transceiver module 60 is in sleep mode according to the difference between the characteristic parameter of the first network signal and the preset parameter being less than a first preset value. The calculation module 12 controls the instruction conversion module 13 to output a sleep instruction to the RF front-end circuit 20.

[0165] For further example, the identification module 11 determines that the difference between the strength of the first network signal and the preset strength is less than the first strength value. The identification module 11 sends the comparison result to the calculation module 12, and the calculation module 12 determines that the difference between the strength of the first network signal and the preset strength is less than the first strength value, and the control instruction conversion module 13 outputs a first control instruction. The first control instruction is used to indicate that the RF front-end circuit 20 and / or the RF transceiver module 60 is in sleep mode.

[0166] In a first optional implementation, the instruction conversion module 13 outputs a first control instruction to the RF front-end circuit 20 , where the first control instruction is used to control the RF front-end circuit 20 to be in a sleep mode.

[0167] In a second optional implementation, the instruction conversion module 13 outputs a first control instruction to the RF transceiver module 60 , where the first control instruction is used to control the RF transceiver module 60 to be in a sleep mode.

[0168] In a third optional implementation, the instruction conversion module 13 outputs the first control instruction to the processor 40, and the processor 40 is used to control the RF transceiver module 60 to be in sleep mode under the action of the first control instruction, and directly control the RF front-end circuit 20 to be in sleep mode; or indirectly control the RF front-end circuit 20 to be in sleep mode through the RF transceiver module 60.

[0169] In other implementations, the three control modes of the first control instruction may be combined with each other.

[0170] Step S230: The identification module 11 determines that the RF front-end circuit 20 and the RF transceiver module 60 are in the wake-up mode according to the difference between the characteristic parameter of the first network signal and the preset parameter being greater than a first preset value. The calculation module 12 controls the instruction conversion module 13 to output a wake-up instruction to the RF front-end circuit 20.

[0171] For further example, the identification module 11 determines that the difference between the strength of the first network signal and the preset strength is greater than or equal to the first strength value. The identification module 11 sends the comparison result to the calculation module 12, and the calculation module 12 determines that the difference between the strength of the first network signal and the preset strength is greater than or equal to the first strength value, and the control instruction conversion module 13 outputs a second control instruction. The second control instruction is used to indicate that the RF front-end circuit 20 and the RF transceiver module 60 are in the wake-up mode.

[0172] In a first optional implementation, the instruction conversion module 13 outputs a second control instruction to the RF front-end circuit 20 , where the second control instruction is used to control the RF front-end circuit 20 to be in a wake-up mode.

[0173] In a second optional implementation, the instruction conversion module 13 outputs a second control instruction to the RF transceiver module 60 , where the second control instruction is used to control the RF transceiver module 60 to be in a wake-up mode.

[0174] In a third optional implementation, the instruction conversion module 13 outputs the second control instruction to the processor 40, and the processor 40 is used to control the RF transceiver module 60 to be in the wake-up mode under the action of the second control instruction, and directly control the RF front-end circuit 20 to be in the wake-up mode; or indirectly control the RF front-end circuit 20 to be in the wake-up mode through the RF transceiver module 60.

[0175] In other implementations, the three control modes of the second control instruction may be combined with each other.

[0176] This embodiment uses the first network signal from the network side device 2000 received by the signal receiving channel 22 of the RF front-end circuit 20 of the monitoring module, collects the characteristic parameters in the first network signal, and compares the characteristic parameters with the preset parameters. It can determine whether the terminal device 1000 is in the standby "stationary" state or the standby "mobile" state. If the terminal device 1000 is in the standby "stationary" state, at this time, the terminal device 1000 basically has no risk of moving out of the coverage area of ​​the anchor network side device 2000, so the RF front-end circuit 20 can still be in the sleep mode; if the terminal device 1000 is in the standby "mobile" state, at this time, the terminal device 1000 has the risk of moving out of the coverage area of ​​the anchor network side device 2000, so the RF front-end circuit 20 can be in the wake-up mode. The RF front-end circuit 20 can send an inquiry signal at least once in the wake-up mode to determine whether the anchor network side device 2000 has changed. Compared with the case where the terminal device 1000 is in the standby "static" state, the RF front-end circuit 20 and the RF transceiver module 60 are also in the wake-up mode, in the present embodiment, it is possible to achieve that when the terminal device 1000 is in the standby "static" state, the RF front-end circuit 20 and the RF transceiver module 60 are in the sleep mode. In the sleep mode, the signal receiving channel 22 of the RF front-end circuit 20 is closed, the signal transmitting channel 21 is closed, and the related control modules and data processing modules of the RF transceiver module 60 can also be closed, which can save a lot of energy and further reduce the power consumption of the terminal device 1000.

[0177] For example, see Fig.13 , after step S200, the method further includes but is not limited to the following steps.

[0178] Step S300: When the supervision module 10 determines that the RF front-end circuit 20 is in the sleep mode, the supervision module 10 is in the takeover mode. In the takeover mode, the supervision module 10 receives and processes a first network signal from a network device.

[0179] It should be noted that in the monitoring mode, the supervision module 10 receives the first network signal from the network side device 2000 by monitoring the RF front-end circuit 20, and the signal received by the supervision module 10 is a coupling signal. In the takeover mode, the supervision module 10 can receive the first network signal.

[0180] When the terminal device 1000 is in standby "stationary" state, the supervision module 10 can receive a periodic first network signal and process the periodic first network signal, so that although the terminal device 1000 has not established a service connection with the network side device 2000, it always maintains network awareness of the anchored network side device 2000, so that the anchored network side device 2000 knows the terminal device 1000 and can quickly find the terminal device 1000 when the terminal device 1000 is called, thereby improving the response speed.

[0181] In this embodiment, the supervision module 10 is in the takeover mode when the RF front-end circuit 20 is in the sleep mode, and further, the RF transceiver module 60 is in the sleep mode. Compared with the RF transceiver module 60 and the RF front-end circuit 20 being both in the wake-up mode, the power consumption of the supervision module 10 in the takeover mode is much less than that of the RF transceiver module 60 and the RF front-end circuit 20 in the wake-up mode due to the relatively few functions and internal components of the supervision module 10, thereby further reducing the power consumption.

[0182] Step S400: When determining that the RF front-end circuit 20 is in the awakening mode, the supervision module 10 is in the monitoring mode.

[0183] Further optionally, the supervision module 10 is also configured to operate in the monitoring mode when the RF front-end circuit 20 is in the wake-up mode. For example, when the RF front-end circuit 20 and the RF transceiver module 60 are in the wake-up mode, the supervision module 10 operates in the monitoring mode to receive the coupling signal.

[0184] In other embodiments, when the RF front-end circuit 20 and the RF transceiver module 60 are in the sleep mode, the supervision module 10 is also in the monitoring mode, maintaining the monitoring of the characteristic parameters of the first network signal, and when the conditions are met, directly controlling or feeding back to the processor 40 to control the RF front-end circuit 20 and the RF transceiver module 60 to switch to the wake-up mode.

[0185] Exemplarily, the RF front-end circuit 20 includes a coupler 23. One end of the monitoring module 10 is electrically connected to the coupler 23.

[0186] The radio frequency system 100 further includes a processor 40 . The processor 40 is electrically connected to the monitoring module 10 and the radio frequency transceiver module 60 .

[0187] See also Fig.14 , Step S100: The monitoring module 10 monitors the first network signal from the network side device 2000, including but not limited to the following steps.

[0188] Step S110 : the monitoring module 10 receives a first network signal from the network-side device 2000 via the coupler 23 .

[0189] The coupler 23 includes power distribution components. The coupler 23 divides one microwave power into several paths in proportion in the microwave system, and then extracts a small portion of the signal from the wireless signal trunk channel. The coupler 23 includes but is not limited to a directional coupler 23, a power divider, and a microwave branching device.

[0190] In an alternative embodiment, see Figure 5 , the RF front-end circuit 20 includes a coupler 23. In other words, the coupler 23 is built into the RF front-end circuit 20 chip and has an external output port.

[0191] The coupler 23 is electrically connected to the identification module 11. Further, an output port of the coupler 23 is electrically connected to the identification module 11. The coupler 23 is configured to couple the radio frequency signal in the radio frequency front-end circuit 20 to the identification module 11.

[0192] In another optional implementation, the monitoring module 10 further includes a coupler 23. In other words, the coupler 23 is built outside the RF front-end circuit 20 chip.

[0193] The coupler 23 is electrically connected to the identification module 11 and the RF front-end circuit 20. Further, an input end of the coupler 23 is electrically connected to the RF front-end circuit 20, and an output end of the coupler 23 is electrically connected to the identification module 11. The coupler 23 is configured to couple the RF signal in the RF front-end circuit 20 to the identification module 11.

[0194] See also Fig.15 , step S210: after the step of the monitoring module 10 comparing the characteristic parameters of the first network signal with the preset parameters. Also includes but is not limited to the following steps.

[0195] Step S240 : the monitoring module 10 generates a first state feedback signal or a second state feedback signal according to the comparison result, and sends it to the processor 40 .

[0196] Specifically, when the comparison result is that the difference between the characteristic parameter of the first network signal and the preset parameter is less than the first preset value, the supervision module 10 generates a first state feedback signal according to the comparison result, and sends the first state feedback signal to the processor 40.

[0197] Specifically, when the comparison result is that the difference between the characteristic parameter of the first network signal and the preset parameter is greater than or equal to the first preset value, the supervision module 10 generates a second state feedback signal according to the comparison result, and sends the second state feedback signal to the processor 40.

[0198] Step S250: the processor 40 controls the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal.

[0199] In an optional implementation, the processor 40 is configured to control the RF front-end circuit 20 and the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal; or, the processor 40 is configured to control the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal, and the RF transceiver module 60 sends a sleep instruction to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the sleep mode; or, the processor 40 is configured to control the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal, and the supervision module 10 converts the wake-up instruction sent by the RF transceiver module 60 into a sleep instruction and sends it to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the sleep mode.

[0200] Step S260: the processor 40 controls the RF transceiver module 60 to be in the wake-up mode according to the second state feedback signal.

[0201] In an optional implementation, the processor 40 is configured to control the RF front-end circuit 20 and the RF transceiver module 60 to be in the wake-up mode according to the second state feedback signal; or, the processor 40 is configured to control the RF transceiver module 60 to be in the wake-up mode according to the second state feedback signal, and the RF transceiver module 60 sends a wake-up instruction to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the wake-up mode; or, the processor 40 is configured to control the RF transceiver module 60 to be in the wake-up mode according to the second state feedback signal, and the supervision module 10 transmits the wake-up instruction sent by the RF transceiver module 60 to the RF front-end circuit 20 to control the RF front-end circuit 20 to be in the wake-up mode.

[0202] For example, see Figures 7 to 9 The instruction conversion module 13 is electrically connected to the RF transceiver module 60 and the RF front-end circuit 20. The RF transceiver module 60 sends a first instruction to the instruction conversion module 13.

[0203] The instruction conversion module 13 is configured to transmit the first instruction to the RF front-end circuit 20 or convert it into a second instruction according to the comparison result between the characteristic parameters of the first network signal and the preset parameters. The first instruction is used to control the RF front-end circuit 20 to be in a wake-up mode. The second instruction is used to control the RF front-end circuit 20 to be in a sleep mode.

[0204] Specifically, when the comparison result indicates that the terminal device 1000 is in a standby "static" state, the instruction conversion module 13 converts the first instruction into a second instruction, and sends the second instruction to the RF front-end circuit 20, so that the RF front-end circuit 20 is in sleep mode. The signal sending channel and the signal receiving channel 22 of the RF front-end circuit 20 are closed. Further optionally, the supervision module 10 receives the first network signal, and the supervision module 10 enters the takeover mode. Further optionally, the supervision module 10 sends the first state feedback signal to the processor 40, and the processor 40 shuts down part of the control circuit and the data processing circuit of the RF transceiver module 60 according to the first state feedback signal to reduce the power consumption of the RF transceiver module 60, and further reduce the standby power consumption of the terminal device 1000.

[0205] For example, see Fig.16 , step S200: determining, according to the characteristic parameters of the first network signal, whether one of the RF front-end circuit 20 and the RF transceiver module 60 is in sleep mode and the other is in wake-up mode, or before both the RF front-end circuit 20 and the RF transceiver module 60 are in sleep mode or both are in wake-up mode, also includes but is not limited to the following steps.

[0206] Step S180: The supervision module 10 determines whether the terminal device 1000 is in a standby state.

[0207] In this embodiment, the supervision module 10 determines that the terminal device 1000 is in a standby state in a variety of ways, including but not limited to a signal receiving channel 22 from the processor 40, the RF transceiver module 60, the RF front-end circuit 20, or a signal transmitting channel 21 of the RF front-end circuit 20.

[0208] The terminal device 1000 being in standby state means that the terminal device 1000 has not established a service connection with the network side device 2000, but maintains network awareness of the network side device 2000.

[0209] Exemplarily, step S180: the supervision module 10 determines whether the terminal device 1000 is in a standby state, including at least one of the following situations:

[0210] In a first optional implementation, the supervision module 10 receives a standby state indication signal from the processor 40, and determines that the terminal device 1000 is in the standby state according to the standby state indication signal.

[0211] Specifically, after the terminal device 1000 and the network side device 2000 finish the last service interaction, the processor 40 determines that the terminal device 1000 is in a standby state, and sends a standby state indication signal to the supervision module 10 .

[0212] The processor 40 can also monitor the power working mode, screen switch events, application working status, the status of the RF transceiver module 60 ending the receiving and sending of service signals, etc. to determine that the terminal device 1000 is in standby mode, and send a standby state indication signal to the supervision module 10.

[0213] In a second optional implementation, the supervision module 10 receives a standby state indication signal from the radio frequency transceiver module 60 , and determines that the terminal device 1000 is in the standby state according to the standby state indication signal.

[0214] Specifically, the RF transceiver module 60 ends sending and receiving service signals to the network side device 2000 , the RF transceiver module 60 determines that the terminal device 1000 is in a standby state, and sends a standby state indication signal to the supervision module 10 .

[0215] In a third optional implementation, the supervision module 10 determines that the terminal device 1000 is in the standby state according to the closing of the signal sending channel of the RF front-end circuit 20 .

[0216] Specifically, the monitoring module 10 monitors the signal of the signal sending channel of the RF front-end circuit 20 and determines that the terminal device 1000 is in the standby state according to the closing of the signal sending channel.

[0217] In a fourth optional implementation, the difference between the signal strength of the first network signal received by the monitoring module 10 from the RF front-end circuit 20 and the preset strength is less than the first strength value, and it is determined that the terminal device 1000 is in the standby state.

[0218] Specifically, the monitoring module 10 monitors that the difference between the signal strength of the first network signal received by the signal receiving channel 22 of the RF front-end circuit 20 and the preset strength is less than the first strength value.

[0219] The preset strength includes but is not limited to the signal strength of the signal receiving channel 22 of the RF front-end circuit 20 receiving the signal from the network side device 2000 at the last time (or the previous times). The supervision module 10 can analyze the coupling signal (the signal obtained by monitoring the first network signal) to obtain the strength of the first network signal, and use the strength as the preset strength.

[0220] The present application does not specifically limit the first strength value. Optionally, the signal strength of the first network signal is close to or the same as the preset strength, indicating that the signal strength of the first network signal is substantially unchanged or changes little, further indicating that the distance between the terminal device 1000 and the network side device 2000 is unchanged or changes little.

[0221] Generally, when the terminal device 1000 is in a standby state, the network side device 2000 will send a wake-up signal or a paging signal to the terminal device 1000 at a certain period to ensure that the terminal device 1000 and the network side device 2000 maintain network perception, so as to facilitate the subsequent rapid establishment of a service connection between the terminal device 1000 and the network side device 2000. If the strength of the first network signal received by the terminal device 1000 is close to the preset strength, it can be explained that the first network signal received by the terminal device 1000 is a wake-up signal or a paging signal, etc., and it can be determined that the terminal device 1000 is in a standby state.

[0222] In a fifth optional implementation, the supervision module 10 detects that the first network signal from the RF front-end circuit 20 is a periodic signal, and determines that the terminal device 1000 is in a standby state.

[0223] Generally, when the terminal device 1000 is in a standby state, the network side device 2000 will send a wake-up signal or a paging signal to the terminal device 1000 at a certain period to ensure that the terminal device 1000 and the network side device 2000 maintain network perception, so as to facilitate the subsequent rapid establishment of a service connection between the terminal device 1000 and the network side device 2000. If the strength of the first network signal received by the terminal device 1000 is close to the preset strength, it can be explained that the first network signal received by the terminal device 1000 is a wake-up signal or a paging signal, etc., and it can be determined that the terminal device 1000 is in a standby state.

[0224] If the monitoring module 10 detects that the first network signal from the RF front-end circuit 20 is a periodic signal, it can be explained that the first network signal received by the terminal device 1000 is a wake-up signal or a paging signal, etc., and it can be determined that the terminal device 1000 is in a standby state.

[0225] Furthermore, if the supervision module 10 monitors that the period of the first network signal from the RF front-end circuit 20 is a preset period, it can further indicate that the first network signal received by the terminal device 1000 is a wake-up signal, or a paging signal, etc., and it can be further determined that the terminal device 1000 is in standby mode.

[0226] The preset period is the period in which the network side device 2000 sends a wake-up signal or a paging signal.

[0227] Optionally, the fifth optional implementation is combined with the fourth optional implementation to further determine whether the terminal device 1000 is in the standby state.

[0228] See also Fig.16 , step S190: If the terminal device 1000 is in the standby state.

[0229] See also Fig.16 , step S200: the supervision module 10 determines, based on the characteristic parameters of the first network signal, that one of the RF front-end circuit 20 and the RF transceiver module 60 is in sleep mode, and the other is in wake-up mode, or that both the RF front-end circuit 20 and the RF transceiver module 60 are in sleep mode or both are in wake-up mode. In the sleep mode, the signal receiving channel 22 of the RF front-end circuit 20 is in a closed state. In the wake-up mode, the signal transmitting channel 21 and the signal receiving channel 22 of the RF front-end circuit 20 are in a working state.

[0230] Generally, when the terminal device 1000 is in a standby state, the network side device 2000 will periodically send a wake-up signal or a paging signal.

[0231] The RF transceiver module 60 needs to be frequently awakened to receive a wake-up signal or a paging signal from the network side device 2000, and the terminal device 1000 and the network side device 2000 maintain network awareness, so as to quickly establish a service connection between the terminal device 1000 and the network side device 2000. The RF transceiver module 60 is frequently awakened, resulting in relatively high power consumption.

[0232] In the implementation mode of the present application, based on the terminal device 1000 being in a standby state, the supervision module 10 monitors the first network signal of the RF transceiver module 60 in real time or periodically to determine that the terminal device 1000 is in a standby "static" state at this time, indicating that the terminal device 1000 is basically at no risk of exceeding the coverage range of the anchor network side device 2000 at this time, and it can be determined that the RF transceiver module 60 and the RF front-end circuit 20 are in a sleep mode, and the supervision module 10 or other devices replace the RF transceiver module 60 and the RF front-end circuit 20 to receive and process the first network signal. There is no need to transmit signals to the network side device 2000, so the number of devices of the supervision module 10 is small and the space occupied is small. The supervision module 10 replaces the RF transceiver module 60 and the RF front-end circuit 20 to receive and process the first network signal, which can greatly reduce power consumption.

[0233] For example, see Fig.17 , step S200: the supervision module 10 determines, according to the characteristic parameters of the first network signal, that one of the RF front-end circuit 20 and the RF transceiver module 60 is in sleep mode, and the other is in wake-up mode, or that both the RF front-end circuit 20 and the RF transceiver module 60 are in sleep mode or both are in wake-up mode, including but not limited to the following steps.

[0234] Step S270: When the terminal device 1000 is in the standby state and the difference between the strength of the first network signal and the preset strength is less than the first strength value, the supervision module 10 determines that the RF front-end circuit 20 and / or the RF transceiver module 60 is in the sleep mode.

[0235] The preset strength includes but is not limited to the signal strength of the signal receiving channel 22 of the RF front-end circuit 20 receiving the signal from the network side device 2000 at the last time (or the previous times). The supervision module 10 can analyze the coupling signal (the signal obtained by monitoring the first network signal) to obtain the strength of the first network signal, and use the strength as the preset strength.

[0236] This application does not make a specific limitation on the first strength value. Optionally, if the signal strength of the first network signal is close to or the same as the preset strength, it means that the signal strength of the first network signal is basically unchanged or changes little, which further means that the distance between the terminal device 1000 and the network side device 2000 is unchanged or changes little, then the risk of the terminal device 1000 exceeding the coverage range of the anchor network side device 2000 is small, and there is no need for the RF front-end circuit 20 and the RF transceiver module 60 to send an inquiry signal, so it can be determined that the RF front-end circuit 20 and / or the RF transceiver module 60 are in sleep mode to save the consumed energy.

[0237] Step S280: When the terminal device 1000 is in a standby state and the difference between the strength of the first network signal and the preset strength is greater than or equal to the first strength value, the supervision module 10 determines that the RF front-end circuit 20 and the RF transceiver module 60 are in a wake-up mode. In the wake-up mode, the RF transceiver module 60 transmits an inquiry signal at least once through the RF front-end circuit 20 to determine whether the network side device 2000 has changed.

[0238] Optionally, the signal strength of the first network signal is significantly different from the preset strength, indicating that the signal strength of the first network signal changes relatively greatly, further indicating that the distance between the terminal device 1000 and the network side device 2000 changes greatly, indicating that the terminal device 1000 is in the standby "mobile" state, then the terminal device 1000 has the risk of exceeding the coverage range of the anchor network side device 2000, and it is determined that the RF front-end circuit 20 and the RF transceiver module 60 are in wake-up mode.

[0239] In the wake-up mode, the RF transceiver module 60 transmits an inquiry signal at least once through the RF front-end circuit 20 .

[0240] In the wake-up mode, the RF transceiver module 60 receives at least one reply signal from the network side device 2000 through the RF front-end circuit 20. The inquiry signal and the reply signal are used to determine whether the network side device 2000 has been changed.

[0241] If the network side device 2000 is changed, the RF transceiver module 60 re-marks the anchored network side device 2000, and the supervision module 10 continues to maintain the monitoring mode and repeats steps S100 to S200 according to the monitoring results.

[0242] If the network side device 2000 has not changed, the RF transceiver module 60 does not need to re-mark the anchored network side device 2000, and the supervision module 10 continues to maintain the monitoring mode and repeats steps S100 to S200 according to the monitoring results.

[0243] Generally, when the terminal device 1000 is in a standby state (idle state, non-service state) in a fixed cell (i.e., the terminal device 1000 is basically not moving), it is necessary to receive a paging signal from the cell (base station) at a certain period so that the terminal device 1000 can maintain contact with the cell (base station, i.e., the network side device 2000). Paging can be quickly implemented when it is necessary to establish a service connection with the terminal device 1000. When the terminal device 1000 does not move at all (fixed in a certain cell), the terminal device 1000 needs to regularly receive signals from the base station to ensure that it can quickly respond to the base station service when necessary. The receiver needs to be frequently awakened and the received signal needs to be processed. The awakening process will bring certain power consumption. In general technology, when the terminal device 1000 is in a standby state, the paging signal (or wake-up signal) received by the RF front-end circuit 20 and the RF transceiver module 60 is frequently awakened.

[0244] The present application proposes a radio frequency system 100 formed based on the recognition state of a supervision module 10 and an identification module 11 (feedback gain circuit). The supervision module 10 can couple power from the coupler 23 of the signal receiving channel 22 of the radio frequency front-end circuit 20 (such as a power amplifier PA) to the power detection module (i.e., the aforementioned identification module 11). The supervision module 10 can monitor the state of the terminal device 1000 (moving or stationary) in real time. The supervision module 10 can directly process the received signal and identify the flag bit (for example, identifying the characteristic period of the paging signal, the signal strength and other characteristics).

[0245] The monitoring module 10 monitors the terminal device 1000 in the following states: before sleep, during sleep, and during wake-up. The three states before sleep, during sleep, and during wake-up can be switched. Furthermore, the states before sleep, during sleep, during wake-up, and online can be switched to each other.

[0246] The pre-sleep stage includes: after the terminal device 1000 has the last service interaction with the anchor base station. The anchor base station transmits a marking signal (such as the aforementioned paging signal) to the terminal device 1000. The supervision module 10 couples the marking signal via the RF front-end circuit 20. For example, the supervision module 10 includes a power detection module, and the power detection module couples the marking signal by electrically connecting the coupler 23 of the RF front-end circuit 20. At this time, the supervision module 10 can interpret the strength of the coupled signal and mark it, such as forming the aforementioned preset strength, and storing the preset strength. So that the marking signal sent by the next base station is directly determined by the supervision module 10, and there is no need for the receiver (RF transceiver module 60) or AP (processor 40) to complete the sleep period.

[0247] The dormant period includes: the anchor base station periodically sends a marking signal, the supervision module 10 couples the marking signal through the RF front-end circuit 20, the supervision module 10 can interpret the strength of the coupled signal, and compare the signal strength of the received marking signal with the aforementioned preset strength. If the signal strength of the received marking signal is close to the preset strength, it is judged that the risk of exceeding the range covered by the anchor base station is small, and it can be determined that the RF transceiver module 60 and the RF front-end circuit 20 enter the dormant mode (dormant period). Further, the supervision module 10 can enter the takeover mode, and the supervision module 10 acts as a small receiver to receive the first network signal from the anchor base station. In this state, there is no need to wake up large devices such as high-power receivers and APs to receive marking signals regularly sent by the anchor base station, saving power consumption of the terminal device 1000.

[0248] The wake-up period includes: if the signal strength of the received marking signal is significantly different from the preset strength, it means that the terminal device 1000 is in a mobile state relative to the anchor base station, and it is judged that the risk of exceeding the range covered by the anchor base station is high, and the RF transceiver module 60 and the RF front-end circuit 20 are determined to enter the wake-up mode (wake-up period). During the wake-up stage, the supervision module 10 implements the state change of the terminal device 1000 by monitoring the strength change, frequency change, or content instruction change of the first network signal, and directly transmits the state change information to the processor 40 (AP). For example, when the supervision module 10 detects the switching of the anchor base station, the processor 40 (AP) notifies the receiver to implement the logic of base station switching.

[0249] The embodiment of the present application can realize the low-power standby architecture of the small receiver through the supervision module 10. In the standby state, the terminal device 1000 will skip the wake-up of higher power consumption devices such as the RF transceiver module 60 (receiver) and the processor 40 (AP). The supervision module 10 realizes this process monitoring. When the standby state changes, it is necessary to start the RF transceiver module 60 (receiver), the processor 40 (AP) and other higher power consumption devices to achieve power saving. By combining the supervision module 10 with the RF front-end circuit 20, a low-power receiver mode in the standby state is realized to save power consumption.

[0251] See also Fig.18 The RF system 100 includes a RF transceiver module 60 , a RF front-end circuit 20 and a monitoring module 10 .

[0252] The RF front-end circuit 20 is electrically connected to the RF transceiver module 60. The RF transceiver module 60 is used to send and receive wireless signals via the RF front-end circuit 20. The relevant contents of the RF front-end circuit 20 provided in this embodiment can refer to the relevant contents of the RF front-end circuit 20 provided in the first embodiment.

[0253] The supervision module 10 is electrically connected to the RF front-end circuit 20. For the contents of the supervision module 10 being electrically connected to the RF front-end circuit 20 in this embodiment, reference may be made to the contents of the RF front-end circuit 20 provided in the first embodiment.

[0254] The supervision module 10 is used to enter a takeover mode when the terminal device 1000 is in a first standby state.

[0255] In the first standby state, the terminal device 1000 has no business contact with the network side device 2000 and the difference between the strength of the first network signal received by the terminal device 1000 and the preset strength is less than the first strength value. Among them, the relevant content of the terminal device 1000 being in the first standby state can be the relevant content of the terminal device 1000 being in the standby "stationary" state described in Example 1 and Example 2. At this time, the terminal device 1000 is in the standby state and the position change of the terminal device 1000 compared with the network side device 2000 is small or basically unchanged. Among them, the preset strength can be the strength of the last time the first network signal was received.

[0256] In this embodiment, the supervision module 10 enters the takeover mode. For details, reference may be made to the supervision module 10 entering the takeover mode described in Embodiment 1 and Embodiment 2.

[0257] The monitoring module 10 is used to receive and process a first network signal from the network side device 2000 in the takeover mode.

[0258] Generally, when the terminal device 1000 is in standby mode, the RF transceiver module 60 receives and processes the first network signal of the network side device 2000 via the RF front-end circuit 20. The power consumption generated by the RF transceiver module 60 and the RF front-end circuit 20 is relatively large.

[0259] In the present application, when the terminal device 1000 is in the first standby state, the supervision module 10 replaces the RF transceiver module 60 and the RF front-end circuit 20 to receive and process the first network signal from the network side device 2000. At this time, the supervision module 10 is relative to a small receiver. Since the supervision module 10 has fewer functions and fewer components, the power consumption is small, so as to reduce the overall power consumption of the terminal device 1000 in the standby state.

[0260] Exemplarily, the RF front-end circuit 20 is configured to be in a sleep mode when the supervision module 10 is in the takeover mode.

[0261] Optionally, when the RF front-end circuit 20 is in sleep mode, both the signal receiving channel 22 and the signal transmitting channel 21 are turned off to reduce power consumption.

[0262] The RF front-end circuit 20 stops receiving the first network signal from the network-side device 2000 in the sleep mode.

[0263] Further, the RF transceiver module 60 is configured to be in a sleep mode when the supervision module 10 is in the takeover mode. For example, the transceiver control unit of the RF transceiver module 60 is turned off. Further, the processor 40 also includes a modem. The modem is electrically connected to the RF transceiver module 60. When the RF transceiver module 60 is in the sleep mode, the modem in the processor 40 can also be in the sleep mode to further reduce the power consumption of the processor 40.

[0264] In this embodiment, when the terminal device 1000 is in a standby static state, the supervision module 10 takes over the RF transceiver module 60 and the RF front-end circuit 20 to receive the paging signal from the network side device 2000, and puts the RF transceiver module 60 and the RF front-end circuit 20 in a sleep mode to reduce power consumption. The RF transceiver module 60 and the RF front-end circuit 20 described in this embodiment are in a sleep mode. In other embodiments, any one of the RF transceiver module 60 and the RF front-end circuit 20 can be in a sleep mode when the supervision module 10 is in the takeover mode.

[0265] Exemplarily, the working mode of the supervision module 10 when the terminal device 1000 is in the second standby state includes a monitoring mode. In the second standby state, the terminal device 1000 has no business contact with the network side device 2000 and the signal strength of the first network signal received by the terminal device 1000 is greater than or equal to the preset strength value.

[0266] For the relevant contents of the second standby state in this implementation mode, reference may be made to the relevant contents of the terminal device 1000 being in the standby “mobile” state in the first and second embodiments.

[0267] Further, the RF front-end circuit 20 is also configured to be in a wake-up mode when the supervision module 10 is in the monitoring mode. The RF front-end circuit 20 sends an inquiry signal to the network side device 2000 at least once in the wake-up mode. In this embodiment, the relevant content of the RF front-end circuit 20 being in the wake-up mode can refer to the relevant content of the RF front-end circuit 20 being in the wake-up mode provided in Example 3.

[0268] In this embodiment, when the terminal device 1000 is in a standby "stationary" state, the supervision module 10 is controlled to be in a supervision mode and the RF front-end circuit 20 and the RF transceiver module 60 are in a sleep mode; in a standby "mobile" state, the supervision module 10 is controlled to be in a monitoring mode and the RF front-end circuit 20 and the RF transceiver module 60 are in a wake-up mode;

[0269] If the terminal device 1000 is in a standby "stationary" state, at this time, the terminal device 1000 has basically no risk of moving out of the coverage area of ​​the anchor network side device 2000, so at this time the RF front-end circuit 20 and the RF transceiver module 60 can be in sleep mode, and the supervision module 10 replaces the RF front-end circuit 20 and the RF transceiver module 60 to receive and process the first network signal; if the terminal device 1000 is in a standby "mobile" state, at this time, the terminal device 1000 has the risk of moving out of the coverage area of ​​the anchor network side device 2000, so at this time the RF front-end circuit 20 can be in a wake-up mode, and the RF front-end circuit 20 can send an inquiry signal at least once in the wake-up mode to determine whether the anchor network side device 2000 has changed. Compared with the case where the terminal device 1000 is in the standby "static" state, the RF front-end circuit 20 and the RF transceiver module 60 are also in the wake-up mode, in the present embodiment, it is possible to achieve that when the terminal device 1000 is in the standby "static" state, the RF front-end circuit 20 and the RF transceiver module 60 are in the sleep mode. In the sleep mode, the signal receiving channel 22 of the RF front-end circuit 20 is closed, the signal transmitting channel 21 is closed, and the related control modules and data processing modules of the RF transceiver module 60 can also be closed, which can save a lot of energy and further reduce the power consumption of the terminal device 1000.

[0270] For example, see Figures 19 to 21 The radio frequency system 100 also includes an identification module 11.

[0271] The identification module 11 is configured to identify the state of the terminal device 1000. The state of the terminal device 1000 includes the first standby state, the second standby state or an online state.

[0272] In the online state, the terminal device 1000 establishes business contact with the network side device 2000.

[0273] Optionally, the identification module 11 determines that the terminal device 1000 is in an online state according to the business contact between the terminal device 1000 and the network side device 2000. The identification module 11 determines that the terminal device 1000 is in a first standby state according to the fact that the terminal device 1000 has no business contact with the network side device 2000, and the signal strength of the first network signal received by the terminal device 1000 is less than a first strength value compared to a preset strength. The identification module 11 determines that the terminal device 1000 is in a second standby state according to the fact that the terminal device 1000 has no business contact with the network side device 2000, and the signal strength of the first network signal received by the terminal device 1000 is greater than or equal to a preset strength value.

[0274] In this embodiment, the state of the terminal device 1000 is identified by the identification module 11. In combination with the foregoing, different modes of the supervision module 10 and different working modes of the RF front-end circuit 20 and the RF transceiver module 60 can be determined according to the different states of the terminal device 1000 identified.

[0275] In an alternative implementation, see Fig.19 , the RF transceiver module 60 includes the identification module 11. In other words, a part of the structure in the RF transceiver module 60 identifies whether the state of the terminal device 1000 is the first standby state, the second standby state or the online state.

[0276] The identification module 11 can determine that the terminal device 1000 has no service connection with the network side device 2000 according to the absence of a transmission signal in the signal transmission channel 21 of the radio frequency transceiver module 60, or the absence of an instruction for scheduling a transmission signal in the received signal of the signal receiving channel 22. And according to the signal strength of the first network signal received by the terminal device 1000 and the preset strength being less than the first strength value, it is determined that the terminal device 1000 is in the first standby state.

[0277] The identification module 11 can determine that the terminal device 1000 has no business contact with the network side device 2000 according to the absence of a transmission signal in the signal transmission channel 21 of the radio frequency transceiver module 60, or the absence of an instruction for scheduling a transmission signal in the received signal of the signal receiving channel 22. And according to the signal strength of the first network signal received by the terminal device 1000 and the preset strength being greater than or equal to the first strength value, it is determined that the terminal device 1000 is in the second standby state.

[0278] The identification module 11 can determine that the terminal device 1000 has business contact with the network side device 2000 and that the terminal device 1000 is online based on the presence of a transmission signal in the signal transmission channel 21 of the RF transceiver module 60, or the presence of an instruction to schedule a transmission signal in the received signal of the signal receiving channel 22.

[0279] Of course, in other implementations, the RF transceiver module 60 can also determine whether the terminal device 1000 has business contact with the network side device 2000 by receiving the signal content from the network side device 2000.

[0280] In another optional implementation, please refer to Fig. 20 The radio frequency system 100 further includes a processor 40. The processor 40 includes the identification module 11. In other words, a part of the structure in the processor 40 identifies that the state of the terminal device 1000 is the first standby state, the second standby state or the online state.

[0281] The identification module 11 in the processor 40 includes but is not limited to a modem. The identification module 11 can identify the state of the terminal device 1000 according to the signal fed back to the processor 40 by the radio frequency transceiver module 60. The identification module 11 in the processor 40 can also determine the state of the terminal device 1000 according to the state of other applications (including but not limited to the switch event of the display screen, the data upload and download amount of the application that needs to use the network, etc.) and sensors (sensors for determining whether the position has changed).

[0282] In another optional implementation, please refer to Fig.21 , the supervision module 10 includes the identification module 11.

[0283] In this implementation manner, the relevant content that the supervision module 10 includes the identification module 11 can refer to the relevant content that the supervision module includes the identification module 11 in the first and second embodiments.

[0284] Please refer to Figure 5 The RF front-end circuit 20 includes a coupler 23. The coupler 23 is electrically connected to the identification module 11. The identification module 11 is configured to monitor or receive a first network signal from the coupler 23, and determine the state of the terminal device 1000 according to at least one of the signal strength, signal frequency, and signal instruction content of the first network signal.

[0285] Specifically, when the supervision module 10 is in the takeover mode, the receiving channel of the RF front-end circuit 20 is closed, and the identification module 11 receives the first network signal from the coupler 23. When the supervision module 10 is in the monitoring mode, the receiving channel of the RF front-end circuit 20 is opened, and the identification module 11 monitors the first network signal from the coupler 23.

[0286] For example, see Fig.21 The supervision module 10 further includes a calculation module 12 and an instruction conversion module 13. The calculation module 12 is electrically connected to the identification module 11. The calculation module 12 is electrically connected to the instruction conversion module 13. The instruction conversion module 13 is electrically connected to the instruction receiving end of the RF front-end circuit 20.

[0287] The relevant contents of the calculation module 12 in this embodiment can refer to the relevant contents of the calculation module 12 in embodiments 1 and 2. The relevant contents of the instruction conversion module 13 in this embodiment can refer to the relevant contents of the instruction conversion module 13 in embodiments 1 and 2.

[0288] See also Fig. 22, the calculation module 12 is configured to control the instruction conversion module 13 to output a first control instruction when the identification module 11 identifies that the terminal device 1000 is in the first standby state. The first control instruction is configured to control the RF front-end circuit 20 to be in the sleep mode. The first control instruction can refer to the relevant content of the second instruction in the first and second embodiments.

[0289] See also Fig.23 The calculation module 12 is configured to control the instruction conversion module 13 to output a second control instruction when the identification module 11 identifies that the terminal device 1000 is in the second standby state. The second control instruction is configured to control the RF front-end circuit 20 to be in a wake-up mode. The second control instruction can refer to the relevant content of the first instruction in Embodiments 1 and 2.

[0290] See also Fig.24 , the calculation module 12 is configured to control the instruction conversion module 13 to output a third control instruction when the identification module 11 identifies that the terminal device 1000 is in the online state. The third control instruction is configured to control the RF front-end circuit 20 to be in a transceiver mode. The RF front-end circuit 20 receives a second network signal from the network side device 2000 and sends a second network signal to the network side device 2000 in the transceiver mode.

[0291] The second network signal includes, but is not limited to, a signal related to a business connection.

[0292] In this implementation, according to different states of the terminal device 1000 , the calculation module 12 determines different control instructions of the instruction conversion module 13 , thereby controlling different working modes of the RF front-end circuit 20 .

[0293] For example, see Fig. 22 , the RF transceiver module 60 is electrically connected to the instruction conversion module 13. The RF transceiver module 60 is configured to send a second control instruction to the instruction conversion module 13. The instruction conversion module 13 is configured to convert the second control instruction into the first control instruction when the terminal device 1000 is in the first standby state.

[0294] The instruction conversion module 13 is also configured to transmit the second control instruction to the instruction receiving end of the RF front-end circuit 20 when the terminal device 1000 is in the second standby state.

[0295] Optional, see Fig. 22 and Fig.23, the RF transceiver module 60 is electrically connected to the instruction conversion module 13. When the terminal device 1000 is in the standby state, the second control instruction is transmitted to the instruction conversion module 13. When the terminal device 1000 is in the first standby state, the computing unit controls the instruction conversion module 13 to convert the second control instruction into the first control instruction according to the recognition result of the recognition module 11, and outputs it to the instruction receiving end of the RF front-end circuit 20. When the terminal device 1000 is in the second standby state, the computing unit controls the instruction conversion module 13 to output the second control instruction to the instruction receiving end of the RF front-end circuit 20 according to the recognition result of the recognition module 11.

[0296] See also Fig.24 The instruction conversion module 13 is also configured to transmit the third control instruction to the instruction receiving end of the RF front-end circuit 20 when the terminal device 1000 is in the online state. The third control instruction is used to control the RF front-end circuit 20 to be in a transceiver mode, so as to facilitate business interaction with the network side device 2000.

[0297] In this embodiment, the instruction conversion module 13 is designed to form control instructions differently in different states, thereby controlling the RF front-end circuit 20 to have different working modes.

[0298] Exemplarily, the radio frequency system 100 further includes a processor 40 . The processor 40 is connected to the monitoring module 10 and the radio frequency transceiver module 60 .

[0299] See also Fig. 22 , the processor 40 is configured to receive a first state feedback signal sent from the supervision module 10 when the identification module 11 identifies that the terminal device 1000 is in the first standby state. The processor 40 controls the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal. For the above content, reference can be made to the relevant content of the processor 40 controlling the RF transceiver module 60 to be in the sleep mode according to the first state feedback signal in Embodiments 1 and 2.

[0300] See also Fig.23 , the processor 40 is configured to receive a second state feedback signal sent from the supervision module 10 when the identification module 11 identifies that the terminal device 1000 is in the second standby state. The processor 40 controls the RF transceiver module 60 to be in the wake-up mode according to the second state feedback signal. For the above content, reference can be made to the relevant content of the processor 40 controlling the RF transceiver module 60 to be in the wake-up mode according to the second state feedback signal in Embodiments 1 and 2.

[0301] See also Fig.24The processor 40 is configured to receive a third state feedback signal sent from the supervision module 10 when the identification module 11 identifies that the terminal device 1000 is in the online state. The processor 40 controls the RF transceiver module 60 to be in the transceiver mode according to the third state feedback signal.

[0302] In this embodiment, the processor 40 can also control the RF transceiver module 60 to be in sleep mode, wake-up mode and transceiver mode according to the state of the terminal device 1000 identified by the identification module 11 and receive the state feedback signal sent by the identification module 11, so as to further reduce power consumption while ensuring the standby function and online communication of the RF system 100.

[0303] A terminal device 1000 provided in an embodiment of the present application includes a radio frequency system 100 as described in any implementation manner of the first embodiment and a radio frequency system 100 as described in any implementation manner of the third embodiment.

[0304] See also Fig.25 , a supervision method provided in Example 4 of this application. Figures 1 to 10 , Figure 18 to Figure 24 , the method is applied to the RF system 100 described in any one of the implementation modes of the third embodiment, and the RF system 100 is applied to the terminal device 1000. The RF system 100 includes a RF transceiver module 60, a RF front-end circuit 20 and a supervision module 10. The RF front-end circuit 20 is electrically connected to the RF transceiver module 60. The supervision module 10 is electrically connected to the RF front-end circuit 20. The method includes but is not limited to the following steps.

[0305] Step S510: The supervision module 10 is in a takeover mode when the terminal device 1000 is in a first standby state. The supervision module 10 is used to receive a first network signal from the network side device 2000 in the takeover mode. In the first standby state, the terminal device 1000 has no business contact with the network side device 2000 and the difference between the strength of the first network signal received by the terminal device 1000 and the preset strength is less than a first strength value.

[0306] The content related to the terminal device 1000 being in the first standby state may be the content related to the terminal device 1000 being in the standby "stationary" state described in Embodiment 1, Embodiment 2, and Embodiment 3. At this time, the terminal device 1000 is in the standby state and the position change of the terminal device 1000 compared to the network side device 2000 is small or substantially unchanged. The preset strength may be the strength of the first network signal received last time.

[0307] In this embodiment, the supervision module 10 enters the takeover mode. For details, reference may be made to the supervision module 10 entering the takeover mode described in Embodiment 1, Embodiment 2, and Embodiment 3.

[0308] Generally, when the terminal device 1000 is in standby mode, the RF transceiver module 60 receives and processes the first network signal of the network side device 2000 via the RF front-end circuit 20. The power consumption generated by the RF transceiver module 60 and the RF front-end circuit 20 is relatively large.

[0309] In the present application, when the terminal device 1000 is in the first standby state, the supervision module 10 replaces the RF transceiver module 60 and the RF front-end circuit 20 to receive and process the first network signal from the network side device 2000. At this time, the supervision module 10 is relative to a small receiver. Since the supervision module 10 has fewer functions and fewer components, the power consumption is small, so as to reduce the overall power consumption of the terminal device 1000 in the standby state.

[0310] See also Fig.26 , after step S510, the method further includes but is not limited to the following steps.

[0311] Step S520: The RF front-end circuit 20 is in the sleep mode when the supervision module 10 is in the takeover mode. The RF front-end circuit 20 is used to stop receiving the first network signal from the network side device 2000 in the sleep mode.

[0312] Optionally, when the RF front-end circuit 20 is in sleep mode, both the signal receiving channel 22 and the signal transmitting channel 21 are turned off to reduce power consumption.

[0313] Further, the RF transceiver module 60 is configured to be in a sleep mode when the supervision module 10 is in the takeover mode. For example, the transceiver control unit of the RF transceiver module 60 is turned off. Further, the processor 40 also includes a modem. The modem is electrically connected to the RF transceiver module 60. When the RF transceiver module 60 is in the sleep mode, the modem in the processor 40 can also be in the sleep mode to further reduce the power consumption of the processor 40.

[0314] In this embodiment, when the terminal device 1000 is in a standby static state, the supervision module 10 takes over the RF transceiver module 60 and the RF front-end circuit 20 to receive the paging signal from the network side device 2000, and puts the RF transceiver module 60 and the RF front-end circuit 20 in a sleep mode to reduce power consumption. The RF transceiver module 60 and the RF front-end circuit 20 described in this embodiment are in a sleep mode. In other embodiments, any one of the RF transceiver module 60 and the RF front-end circuit 20 can be in a sleep mode when the supervision module 10 is in the takeover mode.

[0315] See also Fig.26 , step S530: the supervision module 10 is in a monitoring mode when the terminal device 1000 is in a second standby state. In the second standby state, the terminal device 1000 has no business contact with the network side device 2000 and the signal strength of the first network signal received by the terminal device 1000 is greater than or equal to the preset strength value.

[0316] See also Fig.26 Step S540: The RF front-end circuit 20 is in the wake-up mode when the supervision module 10 is in the monitoring mode. The RF front-end circuit 20 is used to send an inquiry signal to the network side device 2000 at least once in the wake-up mode.

[0317] For the relevant contents of the second standby state in this implementation mode, reference may be made to the relevant contents of the terminal device 1000 being in the standby “mobile” state in the first and second embodiments.

[0318] Further, the RF front-end circuit 20 is also configured to be in a wake-up mode when the supervision module 10 is in the monitoring mode. The RF front-end circuit 20 sends an inquiry signal to the network side device 2000 at least once in the wake-up mode. In this embodiment, the relevant content of the RF front-end circuit 20 being in the wake-up mode can refer to the relevant content of the RF front-end circuit 20 being in the wake-up mode provided in Example 3.

[0319] In this embodiment, when the terminal device 1000 is in a standby "stationary" state, the supervision module 10 is controlled to be in a supervision mode and the RF front-end circuit 20 and the RF transceiver module 60 are in a sleep mode; in a standby "mobile" state, the supervision module 10 is controlled to be in a monitoring mode and the RF front-end circuit 20 and the RF transceiver module 60 are in a wake-up mode;

[0320] If the terminal device 1000 is in a standby "stationary" state, at this time, the terminal device 1000 has basically no risk of moving out of the coverage area of ​​the anchor network side device 2000, so at this time the RF front-end circuit 20 and the RF transceiver module 60 can be in sleep mode, and the supervision module 10 replaces the RF front-end circuit 20 and the RF transceiver module 60 to receive and process the first network signal; if the terminal device 1000 is in a standby "mobile" state, at this time, the terminal device 1000 has the risk of moving out of the coverage area of ​​the anchor network side device 2000, so at this time the RF front-end circuit 20 can be in a wake-up mode, and the RF front-end circuit 20 can send an inquiry signal at least once in the wake-up mode to determine whether the anchor network side device 2000 has changed. Compared with the case where the terminal device 1000 is in the standby "static" state, the RF front-end circuit 20 and the RF transceiver module 60 are also in the wake-up mode, in the present embodiment, it is possible to achieve that when the terminal device 1000 is in the standby "static" state, the RF front-end circuit 20 and the RF transceiver module 60 are in the sleep mode. In the sleep mode, the signal receiving channel 22 of the RF front-end circuit 20 is closed, the signal transmitting channel 21 is closed, and the related control modules and data processing modules of the RF transceiver module 60 can also be closed, which can save a lot of energy and further reduce the power consumption of the terminal device 1000.

[0321] See also Fig. 27 , step S510: before the supervision module 10 is in the takeover mode when the terminal device 1000 is in the first standby state, it also includes but is not limited to the following steps.

[0322] Step S490: The monitoring module 10 determines the state of the terminal device 1000 according to at least one of the signal strength, signal frequency, and signal instruction content of the first network signal received from the RF front-end circuit 20. The states of the terminal device 1000 include a first standby state, a second standby state, and an online state.

[0323] Step S490 specifically includes but is not limited to the following steps.

[0324] In a first optional implementation, the supervision module 10 determines that the state of the terminal device 1000 is the first standby state according to the signal instruction content of the first network signal received from the RF front-end circuit 20 does not include a transmission instruction, and the difference between the signal strength of the first network signal and the preset strength is less than the first strength value. The transmission instruction is an instruction instructing the RF front-end circuit 20 to transmit a signal.

[0325] The signal instruction content of the first network signal does not include a transmission instruction, indicating that the first network signal does not need to schedule the RF front-end circuit 20 to transmit the signal, thereby indicating that the terminal device 1000 and the network side device 2000 are not connected for service at this time.

[0326] In a second optional implementation, the supervision module 10 determines that the state of the terminal device 1000 is the second standby state based on the fact that the signal instruction content of the first network signal received from the RF front-end circuit 20 does not include a transmission instruction, and the difference between the signal strength of the first network signal and the preset strength is greater than or equal to the first strength value.

[0327] In a third optional implementation, the supervision module 10 determines that the state of the terminal device 1000 is an online state according to the signal instruction content of the first network signal received from the RF front-end circuit 20 including a transmission instruction.

[0328] The signal instruction content of the first network signal includes a transmission instruction, indicating that the first network signal needs to schedule the RF front-end circuit 20 to transmit the signal, so as to indicate that the terminal device 1000 and the network side device 2000 are connected for service at this time.

[0329] In this embodiment, the supervision module 10 determines whether the terminal device 1000 and the network side device 2000 are connected for service based on whether the signal instruction content of the first network signal received from the RF front-end circuit 20 includes a transmission instruction.

[0330] Step S490: the monitoring module 10 determines the state of the terminal device 1000 according to at least one of the signal strength, signal frequency, and signal instruction content of the first network signal received from the RF front-end circuit 20. The following steps are also included but not limited to.

[0331] In a fourth optional implementation, the supervision module 10 determines that the state of the terminal device 1000 is the first standby state based on the first network signal received from the RF front-end circuit 20 including a periodic signal, and the difference between the signal strength of the first network signal and the preset strength is less than the first strength value.

[0332] Generally, in the standby state, the paging signal (or wake-up signal) sent by the network side device 2000 is a periodic signal. The supervision module 10 receives the first network signal from the RF front-end circuit 20, including a periodic signal, indicating that the terminal device 1000 is in the standby state at this time. And further, according to the difference between the signal strength of the first network signal and the preset strength being less than the first strength value, it is determined that the state of the terminal device 1000 is the first standby state.

[0333] In a fifth optional implementation, the supervision module 10 determines that the state of the terminal device 1000 is the second standby state based on the first network signal received from the RF front-end circuit 20 including a periodic signal, and the difference between the signal strength of the first network signal and the preset strength is greater than or equal to the first strength value.

[0334] Generally, in the standby state, the paging signal (or wake-up signal) sent by the network side device 2000 is a periodic signal. The supervision module 10 receives the first network signal from the RF front-end circuit 20, including a periodic signal, indicating that the terminal device 1000 is in the standby state at this time. And further, according to the difference between the signal strength of the first network signal and the preset strength being greater than or equal to the first strength value, it is determined that the state of the terminal device 1000 is the second standby state.

[0335] In a sixth optional implementation, the supervision module 10 determines that the state of the terminal device 1000 is an online state according to the first network signal received from the RF front-end circuit 20 not including a periodic signal.

[0336] Generally, in the online state, the service interaction signal sent by the network side device 2000 is a non-periodic signal. The supervision module 10 receives the first network signal from the RF front-end circuit 20 without a periodic signal, indicating that the terminal device 1000 is in the online state.

[0337] Step S510: Before the supervision module 10 is in the takeover mode when the terminal device 1000 is in the first standby state, the supervision module 10 also includes but is not limited to the following steps: the supervision module 10 determines whether the terminal device 1000 is in the standby state. The relevant content of this step can refer to the relevant content of step S180. Among them, determining whether the terminal device 1000 is in the standby state includes any one of the following situations:

[0338] In a first optional implementation, the supervision module 10 receives a standby state indication signal from the processor 40, and determines that the terminal device 1000 is in the standby state according to the standby state indication signal.

[0339] The supervision module 10 receives the standby state indication signal from the radio frequency transceiver module 60 , and determines that the terminal device 1000 is in the standby state according to the standby state indication signal.

[0340] The supervision module 10 determines that the terminal device 1000 is in the standby state according to the closure of the signal sending channel of the RF front-end circuit 20 .

[0341] When the terminal device 1000 is in the standby state, the supervision module 10 determines that the terminal device 1000 is in the first standby state according to the difference between the signal strength of the first network signal received from the RF front-end circuit 20 and the preset strength being less than the first strength value.

[0342] According to the above steps, it is determined that the terminal device 1000 is in the standby state, and the difference between the signal strength of the first network signal received by the signal receiving channel 22 of the RF front-end circuit 20 and the preset strength is less than the first strength value.

[0343] The preset strength includes but is not limited to the signal strength of the signal receiving channel 22 of the RF front-end circuit 20 receiving the signal from the network side device 2000 at the last time (or the previous times). The supervision module 10 can analyze the coupling signal (the signal obtained by monitoring the first network signal) to obtain the strength of the first network signal, and use the strength as the preset strength.

[0344] The present application does not specifically limit the first strength value. Optionally, the signal strength of the first network signal is close to or the same as the preset strength, indicating that the signal strength of the first network signal is substantially unchanged or changes little, further indicating that the distance between the terminal device 1000 and the network side device 2000 is unchanged or changes little.

[0345] Generally, when the terminal device 1000 is in a standby state, the network side device 2000 will send a wake-up signal or a paging signal to the terminal device 1000 at a certain period to ensure that the terminal device 1000 and the network side device 2000 maintain network perception, so as to facilitate the subsequent rapid establishment of a service connection between the terminal device 1000 and the network side device 2000. If the strength of the first network signal received by the terminal device 1000 is close to the preset strength, it can be explained that the terminal device 1000 is in a standby "stationary" state, etc., and it can be determined that the terminal device 1000 is in the first standby state.

[0346] When the terminal device 1000 is in the standby state, the supervision module 10 determines that the terminal device 1000 is in the second standby state according to the difference between the signal strength of the first network signal received from the RF front-end circuit 20 and the preset strength being greater than or equal to the first strength value.

[0347] According to the above steps, it is determined that the terminal device 1000 is in the standby state, and the difference between the signal strength of the first network signal received by the signal receiving channel 22 of the RF front-end circuit 20 and the preset strength is greater than or equal to the first strength value.

[0348] Optionally, the signal strength of the first network signal is somewhat different from the preset strength, indicating that the signal strength of the first network signal changes relatively greatly, further indicating that the distance between the terminal device 1000 and the network side device 2000 changes relatively greatly.

[0349] If the strength of the first network signal received by the terminal device 1000 is relatively different from the preset strength, it can be explained that the terminal device 1000 is in the standby "mobile" state, etc., and it can be determined that the terminal device 1000 is in the second standby state.

[0350] Step S540: the RF front-end circuit 20 is in the wake-up mode when the supervision module 10 is in the monitoring mode. The RF front-end circuit 20 sends an inquiry signal to the network side device 2000 at least once in the wake-up mode, including but not limited to the following steps.

[0351] The RF transceiver module 60 is in the wake-up mode when the supervision module 10 is in the monitoring mode. The RF transceiver module 60 is used to control the RF front-end circuit 20 to send an inquiry signal to the network side device 2000 at least once in the wake-up mode.

[0352] Optionally, the signal strength of the first network signal is significantly different from the preset strength, indicating that the signal strength of the first network signal changes relatively greatly, further indicating that the distance between the terminal device 1000 and the network side device 2000 changes greatly, indicating that the terminal device 1000 is in the standby "mobile" state, then the terminal device 1000 has the risk of exceeding the coverage range of the anchor network side device 2000, and it is determined that the RF front-end circuit 20 and the RF transceiver module 60 are in wake-up mode.

[0353] In the wake-up mode, the RF transceiver module 60 transmits an inquiry signal at least once through the RF front-end circuit 20 .

[0354] In the wake-up mode, the RF transceiver module 60 receives at least one reply signal from the network side device 2000 through the RF front-end circuit 20. The inquiry signal and the reply signal are used to determine whether the network side device 2000 has been changed.

[0355] If the network side device 2000 is changed, the RF transceiver module 60 re-marks the anchored network side device 2000, and the supervision module 10 continues to maintain the monitoring mode and repeats steps S100 to S200 according to the monitoring results.

[0356] If the network side device 2000 has not changed, the RF transceiver module 60 does not need to re-mark the anchored network side device 2000, and the supervision module 10 continues to maintain the monitoring mode and repeats steps S100 to S200 according to the monitoring results.

[0357] The method further includes but is not limited to the following steps.

[0358] Combination Figure 22 to Figure 24, the RF transceiver module 60 outputs the second control instruction or the third control instruction to the identification module 11.

[0359] When the terminal device 1000 is in the first standby state, the identification module 11 converts the second control instruction into a first control instruction. The first control instruction is configured to control the RF front-end circuit 20 to be in the sleep mode.

[0360] Exemplarily, the RF transceiver module 60 is electrically connected to the instruction conversion module 13. The RF transceiver module 60 is configured to send a second control instruction to the instruction conversion module 13. The instruction conversion module 13 is configured to convert the second control instruction into the first control instruction when the terminal device 1000 is in the first standby state.

[0361] When the terminal device 1000 is in the second standby state, the identification module 11 transmits the second control instruction to the RF front-end circuit 20. The second control instruction is configured to control the RF front-end circuit 20 to be in the wake-up mode.

[0362] When the terminal device 1000 is in an online state, the identification module 11 transmits the third control instruction to the instruction receiving end of the RF front-end circuit 20. The third control instruction is configured to control the RF front-end circuit 20 to be in a transceiver mode.

[0363] Optionally, the RF transceiver module 60 is electrically connected to the instruction conversion module 13. When the terminal device 1000 is in the standby state, the second control instruction is transmitted to the instruction conversion module 13. When the terminal device 1000 is in the first standby state, the computing unit controls the instruction conversion module 13 to convert the second control instruction into the first control instruction according to the recognition result of the recognition module 11, and outputs it to the instruction receiving end of the RF front-end circuit 20. When the terminal device 1000 is in the second standby state, the computing unit controls the instruction conversion module 13 to output the second control instruction to the instruction receiving end of the RF front-end circuit 20 according to the recognition result of the recognition module 11.

[0364] The instruction conversion module 13 is also configured to transmit the second control instruction to the instruction receiving end of the RF front-end circuit 20 when the terminal device 1000 is in the second standby state.

[0365] Optionally, the instruction conversion module 13 is further configured to transmit the third control instruction to the instruction receiving end of the RF front-end circuit 20 when the terminal device 1000 is in the online state. The third control instruction is used to control the RF front-end circuit 20 to be in a transceiver mode to facilitate business interaction with the network side device 2000.

[0366] In this embodiment, the instruction conversion module 13 is designed to form control instructions differently in different states, thereby controlling the RF front-end circuit 20 to have different working modes.

[0367] The following is an illustration of the working status of the terminal device 1000 at each stage.

[0368] The terminal device 1000 is in an online state: the RF transceiver module 60 is in a transceiver mode, the RF front-end circuit 20 is in a transceiver mode, and the supervision module 10 is in a monitoring mode; the supervision module 10 monitors the received signal to find that it is a non-periodic signal (service connection), and / or the signal instruction content includes a transmission instruction.

[0369] In the early stage of sleep: the RF transceiver module 60 is in the transceiver mode, the RF front-end circuit 20 is in the transceiver mode, and the supervision module 10 is in the monitoring mode; the supervision module 10 monitors the received signal and finds that it is a periodic signal (no service connection is established), or the signal instruction content does not include a transmission instruction, and the terminal device 1000 switches from the online state to the standby state.

[0370] During the sleep period: if the signal strength change of the received signal monitored by the supervision module 10 is basically unchanged or the change is small, the terminal device 1000 has basically no risk of moving out of the coverage area of ​​the anchor base station, which means that the terminal device 1000 is in the first standby state (standby "static" state) at this time; the supervision module 10 enters the takeover mode, the supervision module 10 sends the first state feedback signal to the processor 40, and the processor 40 controls the RF transceiver module 60 to enter the sleep mode; the supervision module 10 converts the second control instruction into the first control instruction, and the first control instruction causes the RF front-end circuit 20 to enter the sleep mode.

[0371] During the wake-up period: if the signal strength change of the received signal monitored by the supervision module 10 is large, the terminal device 1000 is at risk of moving out of the coverage area of ​​the anchor base station, indicating that the terminal device 1000 is in the second standby state (standby "mobile" state) at this time; the supervision module 10 enters the monitoring mode, the supervision module 10 sends the second state feedback signal to the processor 40, and the processor 40 controls the RF transceiver module 60 to enter the wake-up mode; the supervision module 10 transmits the second control instruction to the RF front-end circuit 20, and the second control instruction causes the RF front-end circuit 20 to enter the wake-up mode.

[0372] In each of the above steps, if the signal monitored by the supervision module 10 is a non-periodic signal (service connection), and / or the signal instruction content includes a transmission instruction, it means that the terminal device 1000 is converted from the standby state to the online state, the RF transceiver module 60 is in the transceiver mode, the RF front-end circuit 20 is in the transceiver mode, and the supervision module 10 is in the monitoring mode.
