Technical Field
The invention relates to the technical field of Internet of things, in particular to an Internet of things terminal, a wake-up method and a wake-up device thereof and a storage medium.
Background
With the development of the internet of things technology, intelligent terminal devices (hereinafter, referred to as internet of things terminals) supporting the internet of things technology are becoming more and more popular. To accelerate the development of the technology of internet of Things, the third generation partnership Project (3rd generation partnership Project, 3GPP) introduced enhanced Machine Type communication (eMTC) and narrowband internet of Things (NB-IoT) technologies in Release 13 (R13).
Since both eMTC and NB-IoT technologies support only narrowband data transmission. Therefore, a User Equipment (UE) supporting eMTC or NB-IoT technology may be referred to as a narrowband terminal (hereinafter, referred to as an internet of things terminal). In practical applications, eMTC and NB-IoT technologies focus more on low power consumption and wide coverage application scenarios, and are applicable to enhanced paging cycle (eDRX).
In order to achieve the purpose of saving power consumption, various power saving technologies are designed for communication technologies used by the internet of things terminal. For example, the transmission power of the base station is properly increased, the time that the terminal of the internet of things is in sleep is prolonged, and the like.
Therefore, in practical applications, for the purpose of saving power, the terminal of the internet of things (e.g., the terminal using NB-IoT as a communication method) may be in the deep sleep mode for a long time. In the sleep state, the terminal of the internet of things does not receive network paging. In other words, the terminal of the internet of things in the sleep state is inaccessible to the network side.
Therefore, in some scenarios (for example, emergency), the network cannot rapidly and timely communicate with the terminal of the internet of things in a sleep state, and user experience is reduced.

Detailed Description
As will be understood by those skilled in the art, as a matter of background, for an existing terminal of the internet of things, when the existing terminal of the internet of things is in a sleep state, the network side cannot page the terminal of the internet of things. In some extreme scenes, such as when a disaster event such as an earthquake occurs, unless the user uses the internet of things terminal by himself, the network side cannot communicate with the internet of things terminal, and cannot get contact with the user in time, so that user experience is greatly influenced, and the guarantee of lives and properties of people is not facilitated.
Specifically, from the perspective of the communication state, the terminal of the internet of things in the sleep state may be substantially in a Power Saving Mode (PSM) or an enhanced discontinuous reception (eDRX) state.
The sleep state may mean that many local modules of the internet of things terminal may be powered off to achieve the purpose of saving power. When data do not need to be received, the terminal of the Internet of things can be switched to a sleep state. And the longer the data is not received, the more modules can be turned off by the terminal of the internet of things, namely, the deeper sleep is realized.
The awake state may be a state as opposed to a sleep state. That is, in the wake-up state, the terminal of the internet of things can communicate with the outside, and the local module is in the power-on state.
For example, when data does not need to be received, the internet of things terminal may close a screen, a radio frequency module, and the like, and reduce the frequency of a Central Processing Unit (CPU). If the terminal does not need to work for a long time, the terminal of the Internet of things can even cut off the power of the memory, only the clock is left to start the terminal at regular time, and the program is read again to run after the terminal is started.
For the NB-IoT terminal, after being awakened periodically, it needs to synchronize with the network signal again, and according to the difference of the PSM or eDRX state, the flows of access request, state update and the like in different layers are performed again.
For PSM, when the terminal of the internet of things enters PSM state, and the duration of camping in PSM state is determined by the network (e.g., core network) negotiating with the terminal of the internet of things. For an internet of things terminal supporting PSM, in an Attach (Attach) or Tracking Area Update (TAU) process, an activation timer value may be applied to a network. When the terminal of the internet of things is transferred from the connection state to the idle state, the timer starts to run, and after the timer expires, the terminal of the internet of things enters a power saving mode (namely, a sleep state).
During PSM, the terminal of the internet of things does not receive a network page. In other words, the internet of things terminal is inaccessible to the network side. Only when the TAU period request timer (T3412) is overtime or the internet of things terminal has service data to actively exit the sleep state, the internet of things terminal exits the PSM mode, enters an idle state, and further enters a connected state to process uplink and downlink services. Wherein, T3412 is specified in attach and TAU messages by the network side, and T3412 is maintained for 54 minutes by default according to the specification of the existing protocol, and can reach 310 hours at most.
Further, the action of the internet of things terminal after processing the data is determined by another Timer (an Active Timer, that is, T3324, which can set time 0-255 seconds). For example, Radio Resource Control (RRC) connection of the terminal of the internet of things is released after the service is completed, the terminal of the internet of things enters an idle state, and starts an activation timer, and after the activation timer expires, the terminal of the internet of things enters a PSM mode (i.e., enters a sleep state).
For eDRX, the paging cycle of eDRX is also specified by the network in the attach and TAU message, the terminal of the internet of things may specify a suggested value to the network, for example, 20 seconds, 40 seconds, 80 seconds, and may reach 40 minutes at maximum, and the network determines the eDRX paging cycle assigned to the terminal of the internet of things as the case may be, and the cycle may be the suggested value specified by the terminal of the internet of things or a value configured by the network for the terminal of the internet of things.
In practical applications, the terminal of the internet of things may request to turn on the PSM and/or eDRX mode in the attach and TAU message, but which or both of the PSM and eDRX mode is finally turned on, and how many periods of the turned-on mode are determined by the network side. The DRX state can be divided into an idle state and a connected state, and so on, and the eDRX can also be divided into an idle eDRX and a connected eDRX.
For the internet of things terminal entering the PSM state or the eDRX state, if the network side needs to communicate with the internet of things terminal, the network side can only wait for the internet of things terminal to automatically exit the PSM mode or the eDRX mode. According to the existing specification, the terminal of the internet of things can actively exit the sleep state only when the service data is generated, otherwise, the network side can communicate with the terminal of the internet of things again only when the timer T3412 configured for the terminal of the internet of things expires.
No matter what form is adopted, the network side can only wait for the terminal of the internet of things in the sleep state to automatically wake up and establish communication with the terminal of the internet of things; for the terminal side of the internet of things, since the terminal side of the internet of things cannot be awakened in the middle of sleeping, important information sent by a network is likely to be missed or delayed to be received.
It should be noted that, in addition to the PSM state and the eDRX state described above, the sleep state in this embodiment may also include other states that require communication to be disconnected from the network side, such as a new power saving mode determined according to a future protocol.
The inventor of the application finds that the technical problem is caused by the lack of an effective awakening mechanism for the terminal of the internet of things. Specifically, since the terminal of the internet of things in the sleep state does not receive paging of the network, the terminal of the internet of things cannot be woken up during the sleep.
The inventor further analyzes and finds that another technology related to power saving is wireless charging. The existing wireless charging methods mainly include electromagnetic induction type, magnetic field resonance type, and radio wave type. Wherein, the radio wave mainly comprises a microwave transmitting device and a microwave receiving device. Some wireless charging technologies declared at present reach more than 20 meters.
And high-power passive signals represented by radio waves can be detected by the terminal of the internet of things in a sleep state.
Therefore, to solve the above technical problem, an embodiment of the present invention provides a method for waking up a terminal of an internet of things, including: in response to detecting the wake-up signal, determining whether the mobile terminal is in a sleep state; and when the judgment result shows that the mobile terminal is in the sleep state, switching to an awakening state according to the historical awakening record. The technical staff in the field understand that, by adopting the scheme of the embodiment, the terminal of the internet of things in the sleep state can be forcibly awakened by the outside (such as the network side), which is beneficial for the network side to rapidly and timely communicate with the terminal of the internet of things in the sleep state.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a method for waking up an internet of things terminal according to an embodiment of the present invention. The internet of things terminal may include devices supporting eDRX and/or PSM, such as mobile devices like mobile phones and notebook computers, and intelligent home appliances; in the wake-up state, the terminal of the internet of things can communicate with the outside (such as a network side), and in the sleep state, the terminal of the internet of things can enter a power saving mode, only passively receives an external passive signal and does not actively receive paging of the network side.
The passive signal may be detected and received based on an existing antenna module in the terminal of the internet of things. Or, a special antenna module may be added in the terminal of the internet of things to detect and receive the passive signal used as the wake-up signal in this embodiment. It should be noted that no matter the existing antenna module or the newly added antenna module, no power support is needed in practical application, so as to better conform to the power saving concept of the internet of things terminal.
Specifically, in this embodiment, referring to fig. 1, the method for waking up the terminal of the internet of things may include the following steps:
step S101, responding to the detection of the wake-up signal, judging whether the mobile terminal is in a sleep state.
And S102, when the judgment result shows that the mobile terminal is in the sleep state, switching to an awakening state according to the historical awakening record.
In one or more embodiments, when the determination result in the step S101 is positive, that is, when the terminal of the internet of things that detects the wake-up signal is in a sleep state, the terminal of the internet of things may execute the step S102 to switch to the wake-up state according to the historical wake-up record.
More specifically, the wake-up signal may be a passive signal. Preferably, the wake-up signal may be a high-power passive signal, so as to increase a signal coverage of the wake-up signal as much as possible, so as to wake up as many terminals of the internet of things as possible.
In one or more embodiments, the wake-up signal may include: the charging system comprises a wireless charging signal from a network side, wherein the wireless charging signal is irrelevant to a charging instruction.
In this embodiment, through pre-negotiation with the terminal of the internet of things, the wireless charging signal from the network side may be marked as a signal dedicated to waking up the device of the internet of things, and the wireless charging signal being unrelated to the charging instruction may refer to: when the wireless charging signal is detected, the internet of things terminal does not perform a wireless charging operation, but recognizes the wireless charging signal as a wake-up signal, and accordingly performs the steps S101 and S102 of this embodiment.
For example, when the step S101 is executed, it may be determined whether the detected source of the wireless charging signal is the network side (e.g., a base station of the network side), and when the wake-up signal is from the network side, it may be determined that the wireless charging signal is the wake-up signal, and then the subsequent operations of the step S101 and the step S102 are continuously executed.
In practical applications, an antenna device may be added to a base station on the network side to transmit the wireless charging signal.
In one or more alternative examples, the wireless charging signal used as the wake-up signal may be different from the wireless charging signal used as the indication to perform wireless charging, for example, the two types of wireless charging signals are respectively transmitted through different frequency bands, so that the terminal of the internet of things can accurately identify the actual use of the detected wireless charging signal.
In one or more embodiments, the sleep state may be selected from: a PSM status; eDRX state. In practical applications, other sleep states may also be applied as needed, which is not described herein.
For example, the switching to the awake state in step S102 may refer to: exiting the PSM state and/or the eDRX state.
In one or more embodiments, the network side may continuously send the wake-up signal for a period of time in order to wake up as many terminals of the internet of things in the cell as possible, and for the terminal side of the internet of things, in order to prevent false repeated wake-up, the terminal of the internet of things may store a historical wake-up record and determine whether to exit the sleep state in response to the currently detected wake-up signal according to the historical wake-up record.
Specifically, the historical wake-up record may include the number of times of waking up the terminal of the internet of things in a historical preset time period. Further, the wake-up times may include the number of times the device is woken up in response to the wake-up signal, and may also include the number of times the device is switched to the wake-up state based on its own traffic demand and/or the expiration of a sleep cycle. The sleep cycle may be determined based on the aforementioned T3412, and may also be a cycle such as an eDRX cycle for controlling the terminal of the internet of things to sleep periodically to save power.
The historical preset time period may be 1 day, 1 hour, and the like, and a person skilled in the art may adjust a specific value of the historical preset time period as needed. In practical application, the historical preset time period may be unilaterally determined by the internet of things device or the base station and notified to the other party, or may be determined by negotiation of the internet of things device when accessing the base station, or may be preset according to a protocol.
Preferably, the starting time of the historical preset time period may be a time when the network side starts to send a wake-up signal.
For example, referring to fig. 2, the step S102 may include the steps of:
step S1021, determining the awakening times in the historical preset time period.
Step S1022, determining whether the number of awakening times within the historical preset time period is less than a preset number of times.
When the determination result in the step S1022 is affirmative, that is, when the number of awakenings within the historical preset time period is less than the preset number, step S1023 is executed to switch to the awakened state.
Otherwise, when the determination result in the step S1022 is negative, that is, when the number of awakenings in the historical preset time period is greater than the preset number, executing step S1024 to continue to be in the sleep state.
Wherein less than may include less than or equal to; alternatively, the greater than may include greater than or equal to.
Therefore, the Internet of things terminal can timely react to the awakening signal on the premise of avoiding mistaken awakening, so that the electricity-saving effect of the Internet of things terminal is ensured, and the Internet of things terminal in a sleep state is ensured to be accessible to the outside when needed.
In a typical application scenario, it may be assumed that the preset number of times is 1, and the historical preset time period is the last 3 hours.
For the terminal of the internet of things which detects the wake-up signal, if the wake-up times of the terminal of the internet of things in the last 3 hours is 0, switching to the wake-up state can be determined.
If the number of awakening of the terminal of the internet of things in the last 3 hours is 3, the terminal of the internet of things can be determined to be in a sleep state continuously.
In one or more embodiments, the continuing to be in the sleep state may refer to: and before the historical preset time period expires, the terminal is always in a sleep state unless the terminal of the Internet of things generates a service requirement and needs to be switched to the awakening state.
In one or more alternative examples, in order to avoid that the communication between the terminal of the internet of things and the network side is disconnected for too long, the continuing to be in the sleep state may further include: and before the preset sleep timer expires, continuing to be in the sleep state, wherein the preset sleep timer can be started when the self-awakening state is switched to the sleep state for the last time within the historical preset time period.
Therefore, in the historical preset time period, in response to the first detection of the wake-up signal, the terminal of the internet of things must be woken up, and then when the wake-up signal is detected again, the terminal of the internet of things may choose not to be woken up all the time, or may start a preset sleep timer when the terminal of the internet of things enters a sleep state again after being woken up for the first time, and actively wake up when the preset sleep timer expires, and receive information of a network side in time.
Preferably, the duration of the preset sleep timer may be equal to or shorter than a sleep cycle determined before the current switching to the awake state. The sleep cycle is configured for the terminal of the internet of things by a network side, and the network side can determine the sleep cycle finally configured for the terminal of the internet of things by referring to the suggested value of the sleep cycle suggested by the terminal of the internet of things.
In one or more embodiments, after the step S102, the wake-up method according to this embodiment may further include the steps of: suggesting an updated suggested value of the sleep cycle based on the wake-up signal prior to switching from the wake-up state to the sleep state.
For example, after switching to the wake-up state, the terminal of the internet of things may access the network and perform a corresponding communication operation, and for the terminal of the internet of things entering the connection state or for the terminal of the internet of things entering the idle state after completing the information receiving operation, a sleep cycle shorter than that configured by the network before the terminal of the internet of things enters the sleep state last time may be suggested to the network side, so as to increase the wake-up frequency and ensure timely communication with the network side.
Preferably, the sleep cycle may be a discontinuous reception cycle.
For example, if the wake-up signal is still present when switching from the wake-up state to the sleep state, the proposed value of the proposed updated sleep cycle is smaller than the proposed value of the sleep cycle determined before the current switching to the wake-up state.
For another example, if the wake-up signal is not present when switching from the wake-up state to the sleep state, the suggested value of the suggested updated sleep cycle is the suggested value of the sleep cycle determined before the first switch to the wake-up state within the historical preset time period.
In a typical application scenario, after the terminal of the internet of things is awakened once (e.g., within a historical preset time period), the network side (e.g., in response to the suggestion of the terminal of the internet of things) may configure the terminal of the internet of things with a sleep cycle that is shorter than a sleep cycle configured to the terminal of the internet of things in an initial state (e.g., before being awakened). Further, the terminal of the internet of things is awakened again after sleeping, (e.g., awakened after the sleep cycle expires or awakened in response to the awakening signal), and if the awakening signal is not detected at this time, the network side (e.g., in response to the suggestion of the terminal of the internet of things) may re-configure the sleep cycle of the initial state for the terminal of the internet of things.
In one or more embodiments, the wake-up method according to this embodiment may further include the steps of: responding to the disappearance of the wake-up signal to reach a preset time length, and judging whether the mobile terminal is in a sleep state; and when the judgment result shows that the mobile terminal is in the awakening state, applying for switching to the sleeping state.
For example, the network side may be applied for the start sleep state (e.g., PSM and/or eDRX state) according to the configuration before entering the sleep state. The suggested content may include an eDRX paging cycle in the suggested initial state.
By the above, by adopting the scheme of this embodiment, the terminal of the internet of things in the sleep state can be forcibly awakened by the outside (e.g., the network side), which is beneficial for the network side to rapidly and timely communicate with the terminal of the internet of things in the sleep state.
Fig. 3 is a schematic structural diagram of a wake-up device of an internet of things terminal according to an embodiment of the present invention. Those skilled in the art understand that the wakeup device 3 of the terminal of the internet of things (hereinafter referred to as the wakeup device 3) in this embodiment is used to implement the method technical solutions in the embodiments shown in fig. 1 and fig. 2.
Specifically, in this embodiment, the wake-up apparatus 3 may include: the first judging module 31, in response to detecting the wake-up signal, judges whether the device is in a sleep state; and the switching module 32 is used for switching to the awakening state according to the historical awakening record when the judging result shows that the sleep state is achieved.
More specifically, the switching module 32 may include: the determining submodule 321 is configured to determine the number of awakenings within a historical preset time period when the determination result indicates that the sleep state is achieved; a switching submodule 322, configured to switch to the wake-up state when the wake-up times within the historical preset time period are smaller than a preset number; or, the keeping sub-module 323 continues to be in the sleep state when the number of awakenings within the historical preset time period is less than a preset number.

For more details of the operation principle and the operation mode of the wake-up apparatus 3, reference may be made to the related description in fig. 1 and fig. 2, and details are not repeated here.
Further, the embodiment of the present invention also discloses a storage medium, on which computer instructions are stored, and when the computer instructions are executed, the technical solution of the method described in the embodiments shown in fig. 1 and fig. 2 is executed. Preferably, the storage medium may include a computer-readable storage medium such as a Non-Volatile (Non-Volatile) memory or a Non-Transitory (Non-transient) memory. The storage medium may include ROM, RAM, magnetic or optical disks, etc.
Further, an embodiment of the present invention further discloses an internet of things terminal, which includes a memory and a processor, where the memory stores computer instructions capable of running on the processor, and the processor executes the computer instructions to execute the technical solutions of the methods in the embodiments shown in fig. 1 and fig. 2.
In a typical application scenario, it is assumed that the terminal of the internet of things is a mobile terminal 10, and the wake-up signal is a wireless charging signal from a network side. Specifically, referring to fig. 4, the mobile terminal 10 may include: a modem 11 for communicating with a network (also referred to as network side); a power management unit 12 for controlling the power on/off state of each module of the mobile terminal 10; a battery 13 for supplying power to one or more modules of the mobile terminal 10 in response to a control instruction of the power management unit 12; a charging control unit 14 that charges the battery 13 in response to a charging instruction; and a wireless charging receiving unit 15, configured to receive a wireless charging signal.
For the mobile terminal 10, the sleep state means that the modem 11 of the mobile terminal 10 is in a sleep state, and at this time, the battery 13 and the modem 11 are in a disconnected state; in contrast, the awake state refers to the state that the modem 11 of the mobile terminal 10 is awake, and the battery 13 supplies power to the modem 11.
Specifically, in the application scenario, with reference to fig. 4 and 5, the wireless charging receiving unit 15 detects a wireless charging signal from the network side, and notifies the power management unit 12 of the detection result.
It should be noted that, in the present application scenario, in response to receiving a wireless charging signal from the network side, the wireless charging receiving unit 15 does not relay the wireless charging signal to the charging control unit 14, and thus, the charging control unit 14 does not charge the battery 13. Alternatively, although the wireless charging receiving unit 15 transmits the detected wireless charging signal to the charging control unit 14, the charging control unit 14 identifies the source of the wireless charging signal, and since the wireless charging signal is from the network side in this application scenario, the charging control unit 14 does not charge the battery 13 as well.
Further, the power management unit 12 determines whether the modem 11 is in a sleep state.
When the determination result indicates that the modem 11 is in the sleep state, the power management unit 12 may wake up the modem 11 to enable the mobile terminal 10 to exit the sleep state (e.g., PSM and/or eDRX state) to communicate with the network.
Further, before the mobile terminal 10 switches from the awake state to the sleep state, the mobile terminal 10 may suggest a sleep cycle (e.g., eDRX paging cycle) shorter than the configured sleep cycle before being awake to the network based on the modem 11.
Further, in conjunction with fig. 4 and fig. 6, the wireless charging receiving unit 15 is in an operating state to continuously (or periodically) detect the wireless charging signal in both the sleep state and the wake-up state.
After the wireless charging receiving unit 15 detects the wireless charging signal from the network side, if the wireless charging receiving unit 15 cannot detect the wireless charging signal again and the time for the wireless charging signal to disappear reaches the preset time period, the wireless charging receiving unit 15 notifies the detected change result to the power management unit 12.
Further, the power management unit 12 determines whether the modem 11 is in a sleep state, and when the determination result indicates that the modem 11 is in an awake state, the mobile terminal 10 may apply for turning on a sleep mode to a network side according to a sleep configuration before being woken up by the modem 11, so as to enter the sleep state (e.g., PSM and/or eDRX state).
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
