Description
Technical Field

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 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, a network side (e.g., a base station on 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. For the state of the Internet of things entering the sleep state, the network side can communicate with the terminal of the Internet of things only after waiting for the terminal of the Internet of things to be self-awakened. For example, only when the TAU period request timer (T3412) is expired 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 a page of the network (i.e., the network side), the terminal of the internet of things cannot be woken up during the sleep state.
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: judging whether an Internet of things terminal in a preset area needs to be awakened or not; when the judgment result shows that the terminal of the Internet of things in the preset area needs to be awakened, sending an awakening signal; and for the awakened terminal of the Internet of things, keeping the terminal of the Internet of things in an awakening state. The technical personnel in the field understand that the scheme of the embodiment of the invention can rapidly and timely awaken the terminal of the Internet of things in the sleep state so as to rapidly send network information to the terminal of the Internet of things in emergency or any other condition with sudden requirements on real-time performance and optimize user experience.
Furthermore, the awakened Internet of things terminal is kept in the awakening state, so that the message needing to be sent to the Internet of things terminal is conveniently and completely sent to the Internet of things terminal in time, and the condition that the Internet of things terminal is switched to the sleep state when transmission is not finished is avoided.
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; for an internet of things terminal in an awakening state, a network side (such as a base station of the network side) can communicate with the internet of things terminal, and for the internet of things terminal in a sleeping state, because the internet of things terminal enters a power saving mode, the internet of things terminal only passively receives an external passive signal and does not actively receive paging of the network side, the network side cannot directly communicate with the internet of things terminal.
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:
and S101, judging whether the terminal of the Internet of things in a preset area needs to be awakened or not.
And S102, sending a wake-up signal when the judgment result shows that the terminal of the Internet of things in the preset area needs to be woken up.
And step S103, for the awakened Internet of things terminal, keeping the Internet of things terminal in an awakening state.
In one or more embodiments, when the determination result in the step S101 is positive, that is, when it is required to wake up the terminal of the internet of things in a preset area, the network side may execute the step S102 to send the wake-up signal.
Further, the preset area may be a signal radiation range of a network side that transmits the wake-up signal.
In one or more embodiments, the network side may be based on a base station and/or a signal transmitter network for transmitting the wake-up signal, and the signal transmitter network may include at least one signal transmitter for transmitting the wake-up signal.
For example, when the network side determines that all internet of things terminals in a cell (cell) need to be woken up, the network side may send the wake-up signal based on a base station associated with the cell. The base station may transmit the wake-up signal with maximum power to ensure as wide a signal coverage area as possible.
In particular, the base station may be configured with an antenna arrangement dedicated to transmitting the wake-up signal.
For another example, to enlarge the signal radiation range, a plurality of signal transmitters may also be arranged to form a signal transmission network, and the signal transmitters may be antenna devices dedicated to transmitting the wake-up signal. In practical application, the base station may control the signal transmitting network to transmit the wake-up signal; or, for the base station configured with the wake-up signal transmitting function, the signal transmitting network may also be controlled to transmit the wake-up signal together.
In one or more embodiments, the wake-up signal may include: and the wireless charging signal is sent by the network side and is irrelevant to the charging instruction.
In this embodiment, through pre-negotiation with the terminal of the internet of things, the wireless charging signal sent by 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 execute wireless charging operation, but identifies the wireless charging signal as an awakening signal so as to switch the state of the internet of things terminal from a sleep state to an awakening state.
In practical applications, an antenna device may be added to a base station on the network side to transmit the wireless charging signal.
For example, the wireless charging signal used as the wake-up signal and the wireless charging signal used as an instruction to perform wireless charging may be distinguished by different frequency bands. That is, the network side can respectively send the two types of wireless charging signals through different frequency bands, so that the internet of things terminal can accurately identify the actual use of the detected wireless charging signals.
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 step S103 of maintaining the terminal of the internet of things in the awake state may refer to: the terminal of the internet of things is not configured to enter a PSM state and/or an eDRX state.
In a preferred example, the network side may not configure the terminal of the internet of things to enter the sleep state in a manner of instructing the terminal of the internet of things to close the sleep mode.
In a variation, the network side may further disallow the terminal of the internet of things to enter the sleep state by rejecting a sleep request of the terminal of the internet of things.
In one or more embodiments, in order to wake up as many terminals of the internet of things in a preset area as possible, the network side may continuously send the wake-up signal for a period of time.
In one or more embodiments, the preset area may be a cell unit, or the preset area may also be determined according to a signal coverage area of a base station.
In one or more embodiments, in step S101, when a service requirement is generated, for example, an emergency needs to communicate with an internet of things terminal in a preset area in an instant manner, the network side may determine that the internet of things terminal in the preset area needs to be woken up.
In one or more embodiments, the wake-up method may further include the steps of: and configuring an updated sleep cycle for the awakened Internet of things terminal, wherein the updated sleep cycle is smaller than the initial sleep cycle of the Internet of things terminal, and the initial sleep cycle is the sleep cycle configured for the Internet of things terminal before the awakening.
Specifically, the sleep cycle configured for the internet of things terminal before the wake-up may refer to: before executing the step S102, the network side configures a sleep cycle for the internet of things terminal.
Therefore, the sleep period configured for the Internet of things terminal is adjusted, the sleep time of the Internet of things terminal when the Internet of things terminal is switched to a sleep state next time can be shortened, and therefore when a message needing to be sent to the Internet of things terminal is generated in the future, the message can be sent to the Internet of things terminal as soon as possible.
Further, the sleep cycle may be determined based on the aforementioned T3412, and the sleep cycle may also adopt a cycle such as an eDRX cycle for controlling the terminal of the internet of things to sleep periodically to save power.
Further, the sleep cycle may be configured for the terminal of the internet of things by a network side, and the network side may 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, in step S103, before the signaling interaction between the wakened terminal of the internet of things and the terminal of the internet of things is completed, the network side may keep the terminal of the internet of things in a wakened state, so as to ensure that the terminal of the internet of things completely receives the message that the network side needs to send to the terminal of the internet of things.
Further, after the signaling interaction with the terminal of the internet of things is completed, at this time, the terminal of the internet of things may be in a connected state or an idle state, and the network side may appropriately allow the terminal of the internet of things to enter a sleep state. Meanwhile, in order to avoid the need of sending new information to the terminal of the internet of things in time, the network side can configure an eDRX paging cycle shorter than that configured before sending the wake-up signal so as to shorten the sleep time of the terminal of the internet of things, and the network side is favorable for realizing communication with the terminal of the internet of things as early as possible in the future.
In one or more embodiments, the wake-up method may further include the steps of: judging whether a preset termination condition is met; and when the judgment result shows that the preset termination condition is met, allowing the awakened Internet of things terminal to be switched to a sleep state.
Specifically, the preset termination condition may be selected from: the sending time of the wake-up signal reaches a preset time; the number of the awakened Internet of things terminals reaches a preset threshold value. Preferably, the preset time period may be 2 hours, and the network side may also adjust a specific value as needed; the preset threshold value can be determined according to the number of terminals of the internet of things which must be awakened in the preset area.
Preferably, when the preset termination condition is met, it means that the network side may not need to wake up the terminal of the internet of things in the preset area.
For example, the network side may allow the woken terminal of the internet of things to switch to a sleep state by instructing the woken terminal of the internet of things to start a sleep mode.
For another example, the network side may also allow the woken terminal of the internet of things to switch to a sleep state by allowing the waken terminal of the internet of things to have a sleep request.
Specifically, the turning on or off of the sleep mode indicates whether the terminal of the internet of things can enter a sleep state, and after the sleep mode is turned on, the terminal of the internet of things can immediately enter the sleep state or can enter the sleep state again when needed later.
Further, when the network side determines that the terminal of the internet of things in the preset area can stop waking up, it may be considered that the network side does not have an emergency situation that needs to contact the terminal of the internet of things in the preset area immediately in a short time, and therefore the waking up method may further include the steps of: and configuring an initial sleep cycle for the Internet of things terminal which is allowed to be switched to the sleep state, wherein the initial sleep cycle is the sleep cycle configured for the Internet of things terminal before the awakening.
In one or more embodiments, when the preset condition is satisfied, the wake-up method may further include the steps of: and stopping sending the wake-up signal.
Specifically, the step of stopping sending the wake-up signal may be executed after the step of configuring the initial sleep cycle for the terminal of the internet of things is completed, or vice versa.
Further, the parameters such as the frequency and the waveform used for transmitting the wireless charging signal may be determined according to the wireless charging technology selected by the network side. Specifically, it may be determined according to the related technical specifications of the wireless charging technology.
Further, the sleep cycle may be a discontinuous reception cycle.
Further, the network may be a core network, such as a 5G core network.
Therefore, by adopting the scheme of the embodiment, the terminal of the internet of things in the sleep state can be awakened quickly and timely, so that the network information can be sent to the terminal of the internet of things as soon as possible in emergency situations or any other situations with sudden requirements on real-time performance, and the user experience is optimized.
Furthermore, the awakened Internet of things terminal is kept in the awakening state, so that the message needing to be sent to the Internet of things terminal is conveniently and completely sent to the Internet of things terminal in time, and the condition that the Internet of things terminal is switched to the sleep state when transmission is not finished is avoided.
