Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a power-saving method, apparatus, device and readable storage medium. Background Technology

[0002] In the design of communication systems for third-generation (3G), fourth-generation (4G), and fifth-generation (5G) mobile communication technologies, different Radio Resource Control (RRC) states for terminals (such as user equipment, UE) are introduced, including: idle state and connected state. The UE enters the connected state when sending or receiving data or when there is service. After the UE has finished sending or receiving data, it can transition from the connected state to the idle state to save power. In the idle state, the terminal only needs to receive necessary synchronization information, paging information, and system information blocks (SIBs), and also needs to perform radio resource management (RRM) measurements for cell selection / reselection and other operations. Compared to the connected state, the power consumption can be significantly reduced, generally reaching tens of mW, which is one-tenth or even less than that of the connected state.

[0003] In the later stages of 4G and 5G New Radio (NR) systems, a new RRC state was introduced: the inactive state. In this state, the terminal's behavior is basically similar to that of the IDLE state. In addition to the aforementioned IDLE state behaviors, it also needs to listen to Radio Access Network (RAN) paging messages and update the RAN notification area (RNA).

[0004] Therefore, it is evident that current terminals still require the transceiver and corresponding modem signal processing modules to periodically turn on to process received signals even in idle or inactive states. Because these radio frequency (RF) and modem modules cannot be completely shut down, communication power consumption cannot be reduced in idle or inactive states. Summary of the Invention

[0005] This application provides a power-saving method, apparatus, device, and readable storage medium to solve the problem of power saving in terminals.

[0006] Firstly, a power-saving method is provided, executed by a terminal, including:

[0007] When the terminal is in a first state, a first action is performed, which is different from the action when the terminal is in a connected state, an idle state, or an inactive state.

[0008] The first state includes one of the following: sleep state, zero power state, near-zero power state, low power state, and ultra-low power state.

[0009] Secondly, a power-saving device is provided for use in a terminal, comprising:

[0010] A first execution module is configured to execute a first action when the terminal is in a first state, the first action being different from the action when the terminal is in a connected state, an idle state, or an inactive state.

[0011] The first state includes one of the following: sleep state, zero power state, near-zero power state, low power state, and ultra-low power state.

[0012] Thirdly, a terminal is provided, comprising: a processor, a memory, and a program stored in the memory and executable on the processor, wherein the program, when executed by the processor, performs the steps of the method described in the first aspect.

[0013] Fourthly, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0014] Fifthly, a program product is provided, the program product being stored in a non-volatile storage medium, the program product being executed by at least one processor to implement the steps of the method as described in the first aspect.

[0015] In a sixth aspect, a chip is provided, the chip including a processor and a communication interface coupled to the processor, the processor being used to run programs or instructions to implement the method as described in the first aspect.

[0016] In this embodiment, the terminal can further reduce receiving, listening, or measuring activities in the first state (e.g., reducing the reception of synchronization information, paging information, or SIBs, and reducing RRM measurements). By reducing receiving, listening, or measuring activities, the receiver or receiving module can be truly shut down in the first state, thereby greatly reducing terminal power consumption and achieving power saving.

[0021] To better understand the embodiments of this application, the following technical points are introduced first:

[0022] I. RRC Status:

[0023] Terminals and networks communicate with each other via wireless channels, exchanging a large amount of information. Therefore, a control mechanism is needed to exchange configuration information and reach an agreement; this mechanism is RRC, or Radio Resource Control. To maintain a relatively fixed communication state for the terminal, different RRC states were introduced in 4G and 5G communication systems, for example:

[0024] Under 5G NR, RRC has three states: IDLE, INACTIVE, and CONNECTED.

[0025] 4G Long Term Evolution (LTE) only has two RRC states: Radio Resource Control Idle (RRC_IDLE) and Radio Resource Control Connected (RRC_CONNECTED). 5G NR introduces a new state—Radio Resource Control Inactive (RRC_INACTIVE).

[0026] The three state characteristics are as follows:

[0027] 1) RRC_IDLE state:

[0028] (a) Selection of Public Land Mobile Network (PLMN);

[0029] (b) Broadcast system information;

[0030] (c) Cell reselection mobility;

[0031] (d) Paging of mobile termination data is initiated by the 5G core network (5G Core, 5GC);

[0032] (e) Paging in the mobile termination data area is managed by 5GC;

[0033] (f) Discontinuous Reception (DRX) configured by Non-Access-Stratum (NAS) for Core Network (CN) paging.

[0034] 2) RRC_INACTIVE state:

[0035] (a) PLMN selection;

[0036] (b) Broadcast system information;

[0037] (c) Cell reselection mobility;

[0038] (d) Paging is initiated by the 5G Access Network (NG-RAN) (RAN Paging);

[0039] (e) RAN-based notification regions (RNAs) are managed by NG-RAN;

[0040] (f) RAN paging DRX configured by NG-RAN;

[0041] (g) Establish a 5GC-NG-RAN connection for the UE (including control plane / user plane);

[0042] (h) UE access layer (AS) messages are stored in NG-RAN and UE;

[0043] (i) NG-RAN knows the RNA to which UE belongs.

[0044] 3) RRC_CONNECTED state:

[0045] (a) Establish a 5GC-NG-RAN connection for the UE (including control plane / user plane);

[0046] (b) UE AS messages are stored in the NG-RAN and the UE;

[0047] (c) NG-RAN knows the cell to which the UE belongs;

[0048] (d) Transmitting unicast data to or from the UE;

[0049] (e) Network control of mobility, including measurement.

[0050] II. Core Network Status:

[0051] Connection management (CM) consists of two parts: the establishment and release of NAS signaling connections between the UE and the Access and Mobility Management Function (AMF). The NAS signaling connection is used for NAS signaling interaction between the UE and the core network. It comprises two connection parts:

[0052] 1) Signaling connection between UE and Access Network (AN) (RRC connection in 3GPP access mode, UE-Non-3GPP InterWorking Function (N3IWF) connection in non-3GPP mode);

[0053] 2) N2 connection between AN and AMF.

[0054] 1.5G System (5GS) Connection Management Status (CM state)

[0055] In 5GS, the signaling connection between the UE and AMF has two states:

[0056] - Connection management idle (CM-IDLE) state;

[0057] -Connection Management (CM-CONNECTED) state;

[0058] The CM state is independent for 3GPP access and non-3GPP access; that is, one access may be in an idle state while the other is in a connected state.

[0059] 1.1CM-IDLE state:

[0060] When the UE is in CM-IDLE state, there are no N2 and N3 connections for that terminal.

[0061] When the UE is in CM-IDLE state and Connection Management Registered (RM-REGISTERED) state (i.e., it has already registered but has no NAS signaling connection), the UE should:

[0062] - Initiate a service-request process in response to a paging request from the network, unless the UE is in Mobile Initiated Connection Only (MICO) mode;

[0063] - Initiate the service-request process if the UE needs to send uplink signaling or data;

[0064] Once the signaling connection between the UE and AN is established (RRC connection in 3GPP access mode, UE-N3IWF connection in non-3GPP mode), the UE enters the CM-CONNECTED state. The transmission of the initial NAS message triggers the UE's state transition from CM-IDLE to CM-CONNECTED.

[0065] When the UE is in CM-IDLE or RM-REGISTERED state (i.e., it has registered but has no NAS signaling connection), the AMF should:

[0066] - Sending a paging message to the UE when the AMF has signaling or called data to send to the UE.

[0067] When the N2 connection is established, the AMF enters the CM-CONNECTED state. Receiving the initial NAS message triggers the AMF's state transition process from CM-IDLE to CM-CONNECTED.

[0068] 1.2CM-CONNECTED state:

[0069] A NAS signaling connection is established between the UE in CM-CONNECTED state and the corresponding AMF. When the UE is in CM-CONNECTED state, the UE should:

[0070] - Enter CM-IDLE state when receiving AN signaling connection (i.e., RRC connection release (3GPP access) or UE-N3IWF connection release (non-3GPP access)).

[0071] When the UE is in CM-CONNECTED state, the AMF should:

[0072] - Enter CM-IDLE state when the Next Generation Application Protocol (NGAP) signaling connection and N3 user plane connection are released.

[0073] When a UE in CM-CONNECTED state enters RRC_Inactive state:

[0074] -UE reachability is managed by the access network.

[0075] -UE paging is managed by the access network.

[0076] - The UE needs to simultaneously listen for paging of the core network ID (e.g., 5G S-Temporary Mobile Subscription Identifier, 5G S-TMSI) and paging of the RAN-ID.

[0077] III. Wake-up signaling (WUS)

[0078] In LTE and NR systems, in order to save power, a wake-up signal is introduced in the connected state and the idle / inactive state. The purpose is to enable the terminal, when configured with connected state DRX or idle state DRX, to listen to the Physical Downlink Control Channel (PDCCH) as needed, whether to wake up from the sleep state (i.e., DRX off state) (i.e., enter the DRX on state).

[0079] Specifically, in the connected state, the terminal listens to the DCP signal sent by the network side at the corresponding monitor occasion to determine whether to return from the DRX off state to the active state, thereby listening to the PDCCH and completing the corresponding connected state scheduling and data transmission. In the idle / inactive state, the terminal listens to the WUS or Permanent Equipment Identifier (PEI) message sent by the network side at the corresponding monitor occasion in each DRX cycle to determine whether it needs to listen to the PDCCH and / or Physical Downlink Shared Channel (PDSCH) messages corresponding to paging messages in one or more subsequent DRX cycles.

The base station is not limited to the specified technical terms. It should be noted that in this embodiment of the application, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0084] The following description, in conjunction with the accompanying drawings, details a power-saving method, apparatus, device, and readable storage medium provided in this application through some embodiments and application scenarios.

[0085] See Figure 2 This application provides a power-saving method, which can be executed by a terminal. The specific steps include: step 201.

[0086] Step 201: When the terminal is in a first state, execute a first action, which is different from the action when the terminal is in a connected state, an idle state, or an inactive state;

[0087] The first state includes one of the following: sleep state, zero power state, near zero power (AZP or Near Zero Power, NZP) state, low power (LP) state, and ultra low power (ULP or SLP) state.

[0088] It should be noted that the terminal's receiving, listening, or measuring behavior in the first state is less than that when the terminal is in the connected state, idle state, or inactive state.

[0089] The first state mentioned above is a newly defined terminal state. It can be a newly defined RRC state, that is, an RRC state other than the existing three RRC states: RRC connected state (RRC_CONNECTED), RRC idle state (RRC_IDLE), and RRC inactive state (RRC_INACTIVE); or a sub-state of an existing RRC state, such as a sub-state of the RRC idle state; or a newly defined core network state, that is, a core network state other than the existing core network connected state (such as connection management CM_CONNECTED) and core network idle state (CM_IDLE).

[0090] The power consumption of the terminal in the first state is lower than the power consumption of the terminal when it is in a connected state, an idle state, or an inactive state. Specifically, the power consumption includes power consumption per unit time, power consumption for the same duration, or power value.

[0091] In one embodiment of this application, the first action includes one or more of the following:

[0092] (1) Turn off the radio frequency (RF) module; it is understood that the radio frequency module can also be called a radio frequency unit, such as an antenna, at least one amplifier, transceiver, coupler, low noise amplifier, duplexer, etc.

[0093] (2) Turn off the baseband (BB) module;

[0094] (3) Turn off the corresponding function module of the modem;

[0095] Understandably, a modem, also known as a modem processor, primarily handles wireless communication, similar to a baseband processor. If the modem is integrated into the processor, the first step would be to disable the corresponding modem function module within the processor.

[0096] (4) No synchronization is performed;

[0097] (5) No reference signal is received;

[0098] Examples include the Synchronization Signal and PBCH block (SSB), Tracking Reference Signal (TRS), Channel State Information Reference Signal (CSI_RS), and Demodulation Reference Signal (DMRS).

[0099] (6) Do not listen to PDCCH;

[0100] (7) Do not receive paging messages;

[0101] (8) Do not receive short messages;

[0102] (9) Do not receive system information;

[0103] (10) No Radio Resource Management (RRM) measurements were performed;

[0104] (11) Do not accept system information update instructions;

[0105] (12) Do not receive messages from the Public Warning System (PWS);

[0106] For example, it does not receive messages from the Earthquake and Tsunami Warning System (ETWS); or it does not receive messages from the Commercial Mobile Alert System (CMAS).

[0107] (13) No Public Land Mobile Network (PLMN) selection is performed;

[0108] (14) No cell selection reselection is performed;

[0109] (15) Do not perform (or do not need to perform) core network registration, camping, or attachment.

[0110] In one embodiment of this application, the action in the first action that the terminal does not perform (or does not need to perform) is achieved by one or more of the following:

[0111] (1) No corresponding requirements are defined;

[0112] (2) The terminal does not meet (or does not need to meet) the requirements corresponding to the idle state, inactive state, or connected state in the first state;

[0113] (3) Agreement stipulation, that is, the specific actions that the terminal does not need to perform in the first state are clearly stated in the agreement;

[0114] (4) The terminal makes autonomous decisions based on the implementation.

[0115] The above-mentioned "not defining corresponding requirements" means that the protocol does not define the requirements for the corresponding behavior of the terminal in the first state.

[0116] The terminal described above does not need to meet the requirements corresponding to the idle state, inactive state, or connected state in the first state. The requirements corresponding to the idle state, inactive state, or connected state refer to the requirements for the terminal's behavior in the idle state, inactive state, or connected state as defined in the protocol.

[0117] In one embodiment of this application, the method may further include: performing a second action when the terminal determines that it needs to enter (e.g., determines that it needs to enter or determines that it can enter) or the network side configures entry (e.g., configures that it needs to enter or configures that it can enter) the first state;

[0118] The second behavior includes one or more of the following:

[0119] (1) Radio Resource Control Connection Release (RRC_Release) procedure;

[0120] (2) Detach process;

[0121] (3) Stop, restart, suspend or continue the first timer or the first counter, wherein the first timer is the timer corresponding to the idle state, the inactive state or the connected state, and the first counter is the counter corresponding to the idle state, the inactive state or the connected state;

[0122] For example, the counters or timers (N310, N311, T310) corresponding to radio link monitoring (RLM) / beam failure detection (BFD) in the RRC_CONNECTED state, the timers or counters during the RRC connection establishment process (T311, T312, etc.); and the timers or counters corresponding to mobility judgment in the RRC_IDLE / INACTIVE state.

[0123] (4) Release part or all of the configuration of the second state, which is the idle state, inactive state or connected state before entering the first state;

[0124] That is, it does not save part or all of the configuration of the idle, inactive or connected state before entering the first state.

[0125] Optionally, the configuration may include: RRC configuration, system messages, core network, or NAS configuration, etc.

[0126] Optionally, the idle state may include: RRC_IDLE or CM_IDLE; the connected state may include: RRC_CONNECTED or CM_CONNECTED.

[0127] For example:

[0128] a) When transitioning from the RRC_CONNEDCTED state to the first state (e.g., RRC_SLEEP), some or all of the RRC configuration is released;

[0129] b) When transitioning from the RRC_INACTIVE state to the first state (e.g., RRC_SLEEP), some or all of the RRC configuration and / or some or all of the system messages are released.

[0130] c) When transitioning from the RRC_IDLE state to the first state (e.g., RRC_SLEEP), some or all of the RRC configurations that remain effective in IDLE are released, and / or some or all of the system messages.

[0131] d) Further, when entering the first state (such as RRC_SLEEP) from the RRC_IDLE, RRC_INACTIVE, or RRC_CONNECTED state, release some or all of the NAS-related configurations, including one or more of the following: registration information, DRX configuration information, and Tracking Area (TA) related configurations.

[0132] (5) The process of entering the first state (e.g., RRC_SLEEP) from the idle state, inactive state, or connected state.

[0133] The process may include: the terminal determining whether to enter the first state based on preset conditions or network-side configuration, and then entering the first state from an idle state, an inactive state, or a connected state. The preset conditions are either protocol agreements or network configurations.

[0134] In one embodiment of this application, the first action may further include one or more of the following:

[0135] (1) Turn on the receiver or receiving module corresponding to the first state;

[0136] It is understandable that the receiver or receiving module corresponding to the first state is an additional receiver or receiving module. For example, the receiver may include: a near-zero power receiver, a zero power receiver, an ultra-low power receiver, a low power receiver, or a power-saving mode receiver; the receiving module may include: a near-zero power receiving module, a zero power receiving module, an ultra-low power receiving module, a low power receiving module, or a power-saving mode receiving module.

[0137] For example, near-zero power receivers do not require complex RF modules (or RF units) for signal detection (such as amplification, filtering, quantization, etc.) and modulation / demodulation signal processing. They can achieve the purpose of waking up the terminal by relying only on passive matched filtering and low-power signal processing.

[0138] (2) Receive a wake-up signal (WUS) or power-on signal (POS) at a preset resource location;

[0139] On the terminal side, the wake-up signal or activation signal sent by the network side can activate the newly introduced receiver or receiving module, thereby receiving the wake-up / activation notification, that is, receiving the wake-up signal or activation signal through the aforementioned additional receiver or receiving module.

[0140] Optionally, the resource location may include one or more of the following: time-domain resource location, frequency-domain resource location, spatial-domain resource location, code-domain resource location, and beam resource location.

[0141] Optionally, the preset resource location is configured on the network side. For example, the preset resource location is configured by the network side before the terminal enters the first state.

[0142] In one embodiment of this application, the wake-up signal or activation signal received at a preset resource location is different from the wake-up signal or activation signal received by the terminal in a connected state, an idle state, or an inactive state; optionally, the preset resource location is agreed upon by a protocol or configured on the network side.

[0143] Specifically, this is reflected in:

[0144] (i) Different receivers: In the RRC_CONNECTED state, the corresponding PDCCH is received through the MODEM module; in the RRC_IDLE / INACTIVE state, the corresponding PDCCH and / or sequence is received through the MODEM module; in the first state (RRC_SLEEP), the corresponding sequence is received through the newly introduced receiver.

[0145] (ii) Different functions: In the RRC_CONNECTED state, the UE is woken up from the DRX_OFF state and continues to listen to the PDCCH; in the RRC_IDLE / INACTIVE state, the UE is woken up from the DRX_OFF state and continues to listen to the PDCCH and / or Paging message (or short message); in the first state (RRC_SLEEP), the UE is woken up from the first state (RRC_SLEEP) and enters the IDLE / INACTIVE / CONNECTED state.

[0146] In one embodiment of this application, the wake-up signal or activation signal includes an on-off keying signal, so that the receiver or receiving module can obtain the wake-up signal or activation signal through simple energy detection and subsequent possible sequence detection and identification processes.

[0147] In one embodiment of this application, the wake-up signal or activation signal is sent on demand by the network side. That is, when it is necessary to exit the terminal from the first state, or enter the idle state, inactive state, or connected state, the wake-up signal or activation signal is sent to the terminal.

[0148] (3) Listen to a first signal, the first signal being used to indicate area information, optionally, the area including one or more of the following: cell, radio access network notification area (RAN Notification Area, RNA), tracking area, new area for the first state (a newly defined new area for the first state (e.g., RRC_SLEEP));

[0149] In one embodiment of this application, the first signal includes a sequence agreed upon by a protocol or configured on the network side, the sequence being used to indicate information about the area where the terminal is located.

[0150] Optionally, the correspondence between the sequence and the region information is agreed upon by the protocol or configured on the network side.

[0151] Specifically, the first signal used to indicate area information means that the first signal is applied to the area corresponding to the first state, or the area corresponding to the first state of the first signal, and may include at least one of the following:

[0152] a. One or more cells;

[0153] b. One or more RNAs;

[0154] c. One or more TAs.

[0155] (4) Update the region;

[0156] Optionally, the region includes one or more of the following: cell, RNA, tracking region, and a new region for the first state (a newly defined new region for the first state (e.g., RRC_SLEEP));

[0157] Optionally, the updated region includes one of the following:

[0158] (i) When the terminal determines that the area it is in has changed, it enters the idle state, inactive state or connected state before the first state, and then updates the area;

[0159] (ii) When the terminal determines that the area it is in has changed, it enters the idle state, inactive state or connected state and then updates the area.

[0160] (iii) In the first state update region.

[0161] in,

[0162] a) When the region is a cell, the region needs to be updated every time the terminal switches to a new cell;

[0163] b) When the region is RNA, the region needs to be updated every time the terminal changes to a different RNA (the specific update process can reuse the INACTIVE state process, or update after returning from the RRC_SLEEP state to the IDLE / INACTIVE state).

[0164] c) When the region is TA, the region needs to be updated every time the terminal changes to a new TA (the specific update process can reuse the process of IDLE state, or update after returning to IDLE state from the first state (e.g., RRC_SLEEP)).

[0165] d) When the region is newly defined for the first state (e.g., RRC_SLEEP), the region needs to be updated every time the terminal changes to a new region.

[0166] (5) Receive system information (SI) change indication, wherein the system information change indication is received by a wake-up signal or activation signal of the first state;

[0167] For example, after receiving an SI change instruction, it returns to IDLE state and then receives the updated SI.

[0168] For example, after receiving the SI change instruction, it returns to the IDLE state, then synchronizes, receives the SSB, and then receives the latest SI.

[0169] (6) Start the second timer. If the second timer expires, enter the idle state, inactive state or connected state before the first state, or enter the idle state, inactive state or connected state; or, if the second timer expires, determine whether the region should be updated, or update the region directly.

[0170] In one embodiment of this application, the receiver or receiving module corresponding to the first state has one or more of the following characteristics:

[0171] (1) No specific radio frequency signal detection and / or modulation / demodulation signal processing is performed;

[0172] Optionally, specific radio frequency signal detection refers to complex radio frequency signal detection, including but not limited to amplification, filtering, quantization, etc.

[0173] (2) Perform passive matched filtering and / or first signal processing, wherein the power consumption of processing the first signal is less than or equal to the power consumption of signal processing in the third state, the third state being an idle state, an inactive state, or a connected state before entering the first state.

[0174] In the embodiments of this application, the receiver or receiving module corresponding to the first state does not require complex RF signal detection (such as amplification, filtering, quantization, etc.) and MODEM signal processing. It can achieve the purpose of waking up or activating the terminal by relying only on passive matched filtering and low-power signal processing.

[0175] (3) When the terminal is in an idle state, an inactive state or a connected state, turn off or start the receiver or receiving module corresponding to the first state.

[0176] In one embodiment of this application, the method further includes: if the wake-up signal or activation signal is received, performing a third action;

[0181] (3) Enter the idle state, inactive state or connected state.

[0182] In one embodiment of this application, the method further includes:

[0183] If the terminal determines to exit (e.g., it determines that it needs to exit, or it determines that it can exit) or the network configuration exits (e.g., the configuration requires exiting, or the configuration allows exiting) and enters the first state, the fourth action is executed;

[0184] The fourth action includes one or more of the following:

[0185] (1) Trigger the terminal to execute a pre-set hardware process;

[0199] (2) Turn off the baseband module;

[0200] (3) Disable the corresponding function modules of the modem;

[0230] For example, near-zero power receivers do not require complex RF modules (or RF units) for signal detection (such as amplification, filtering, quantization, etc.) and modulation / demodulation signal processing. They can achieve the purpose of waking up the terminal by relying only on passive matched filtering and low-power signal processing.

[0231] (2) Receive a wake-up signal or activation signal at a preset resource location;

[0239] (3) When the terminal is in an idle state, an inactive state or a connected state, turn off or start the receiver or receiving module corresponding to the first state.

[0240] In one embodiment of this application, the wake-up signal or activation signal received at a preset resource location is different from the wake-up signal or activation signal received by the terminal in a connected state, an idle state, or an inactive state; wherein, the preset resource location is agreed upon by a protocol or configured on the network side.

[0241] In one embodiment of this application, the wake-up signal or activation signal includes a power button control signal.
