Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] Mobility management technology has been proposed in communication technology. Mobility management is a fundamental function in wireless mobile communication, used to ensure that the communication link between network equipment and terminals is not interrupted due to terminal movement. Generally, mobility management can be divided into RRC idle-state mobility management and RRC connected-state (RRC_CONNECTED) mobility management based on the terminal's radio resource control (RRC) state. RRC idle-state mobility management includes the cell selection / reselection process. RRC connected-state mobility management includes the cell handover process. When a terminal performs mobility management (e.g., cell selection, reselection, or handover), it needs to acquire measurement results and perform mobility management based on these results.

[0003] However, even after the introduction of wake-up radio technology, how to manage mobility remains a blank. Summary of the Invention

[0004] This application provides a communication method and apparatus that enables mobility management based on low-power signals. Using low-power signals for mobility management can also reduce the power consumption of the terminal.

[0005] Firstly, a communication method is provided. This method can be executed by a terminal, for example, by the terminal itself, or by a module applied to the terminal (e.g., a processor, chip, or chip system), or by a logical node, logical module, or software capable of implementing all or part of the terminal's functions. Taking the application of this method to a terminal as an example, in this method, the terminal can receive configuration information from a network device. The configuration information includes at least a measurement object and measurement events associated with the measurement object. The measurement object includes a first cell covered by the network device, and the measurement events are used to trigger mobility management. Thus, the terminal can measure the first cell based on a low-power signal provided by the first cell to obtain a first measurement result, thereby sending a measurement report to the network device. The first measurement result is used to trigger the measurement event. The measurement report indicates that the measurement event has been triggered.

In this way, on the one hand, the terminal uses a low-power signal for measurement, avoiding the need for the terminal to turn on its main receiver, thus reducing the terminal's power consumption.

[0039] I. Terminal

[0040] A terminal is an entity on the user side used to receive signals, or transmit signals, or both. Terminals are used to provide users with one or more of the following: voice services and data connectivity services. A terminal can be a device that includes wireless transceiver capabilities and can cooperate with network equipment to provide communication services to users. Specifically, a terminal can refer to user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication equipment, user agent, user apparatus, or roadside unit (RSU).

The terminal can also be a terminal in a 5G system or a terminal in a next-generation communication system; this application does not limit the specific application to these possibilities.

[0041] The embodiments of this application do not limit the device form of the terminal. The device used to implement the functions of the terminal can be the terminal itself; it can also be a device that supports the terminal in implementing the functions, such as a chip system. The device can be installed in the terminal or used in conjunction with the terminal. In the embodiments of this application, the chip system can be composed of chips or can include chips and other discrete devices.

[0042] II. Network Equipment

[0043] A network device is an entity on the network side used to transmit signals, or receive signals, or both. A network device can be a means deployed in a radio access network (RAN) to provide wireless communication functionality to terminals.

[0044] In one possible scenario, network equipment can be devices with base station functions, such as evolved NodeBs (eNodeBs), transmitting and receiving points (TRPs), transmitting points (TPs), next-generation NodeBs (gNBs), next-generation base stations in 6G mobile communication systems, integrated access and backhaul (IAB) nodes, and non-terrestrial network equipment in non-terrestrial networks (NTNs), which can be deployed on high-altitude platforms or satellites. Network equipment can be transmitting and receiving points (TRPs), base stations, and various forms of control nodes, such as network controllers and radio controllers. Specifically, network equipment can be various forms of macro base stations, micro base stations (also known as small cells) in heterogeneous network (HetNet) scenarios, relay stations, access points (APs), radio network controllers (RNCs), node Bs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home evolved node Bs, or home node Bs (HNBs)), baseband units (BBUs) and remote radio units (RRUs) in distributed base station scenarios, transmitting and receiving points (TRPs), transmitting points (TPs), mobile switching centers, etc., and can also be base station antenna panels. Control nodes can connect to multiple base stations and configure resources for multiple terminals covered by multiple base stations. In systems employing different wireless access technologies, the names of devices with base station functions may differ.For example, it could be a gNB in ​​5G, network-side equipment in networks after 5G, or network equipment in future evolved public land mobile networks (PLMNs), or equipment that performs base station functions in device-to-device (D2D) communication, machine-to-machine (M2M) communication, or vehicle-to-everything (V2X) communication. This application does not limit the specific name of the network equipment. Network equipment can also be a baseband pool (BBU pool) and RRU under an open RAN (O-RAN or ORAN), cloud radioaccess network (CRAN), etc.

[0045] All or part of the functions of the network device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform). The network device in this application can also be a logical node, logical module, or software capable of implementing all or part of the functions of a network device.

[0046] In another possible scenario, multiple network devices collaborate to assist terminals in achieving wireless access, with each network device performing a portion of the base station's functions. For example, network devices may include a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). CUs and DUs can be separate entities or included in the same network element, such as a baseband unit (BBU). RUs may be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). It is understood that network devices can be CU nodes, DU nodes, or devices comprising both CU and DU nodes. Furthermore, CUs can be classified as network devices in the access network (RAN) or in the core network (CN), without limitation.

[0047] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0048] In this embodiment, the form of the network device is not limited. The device used to implement the function of the network device can be the network device itself, or it can be a device that supports the network device in implementing the function, such as a chip system. The device can be installed in the network device or used in conjunction with the network device.

[0049] To facilitate understanding of the content of this solution, some terms used in the embodiments of this application will be explained below, so that those skilled in the art can understand them. This part is only for the purpose of understanding and should not be regarded as a specific limitation of this application.

[0050] I. Carrier aggregation (CA) technology

[0051] In carrier aggregation technology, a terminal can communicate simultaneously on multiple cells, thereby supporting high-speed data transmission. These multiple cells may include a primary carrier cell (PCell) and at least one secondary carrier cell (SCell). The primary carrier cell can be simply referred to as the primary cell, and the secondary carrier cell as the secondary cell. For ease of description, the following description uses primary and secondary cells as examples and should not be considered as a limitation of this application.

[0052] In this context, the primary cell is the cell where the terminal and network equipment establish an initial connection, or the cell where the terminal re-establishes a radio resource control (RRC) connection, or the primary cell that performs handover operations. The primary cell is responsible for RRC communication with the terminal. Generally, in CA technology, the primary cell can operate on the primary component carrier (PCC).

[0053] Compared to the primary cell, a secondary cell can provide additional radio resources. Generally, in CA technology, a secondary cell can operate on a secondary component carrier (PCC).

[0054] Optionally, the primary cell and secondary cell can be deployed co-site or non-co-site. Co-site deployment can be understood as having two carriers at the same site, such as the same network device; these two carriers are the co-site carriers. These two carriers can belong to the primary cell and the secondary cell, respectively. Non-co-site deployment can be understood as having carriers at different sites; for example, one network device (called the primary network device) has its carriers belonging to the primary cell, while another network device (called the secondary network device) has its carriers belonging to the secondary cell, and these two network devices are at different sites.

[0055] II. Dual Connectivity (DC) Technology

[0056] To improve data transmission speed and reliability, a terminal can simultaneously connect to multiple network devices of the same or different standards. These multiple network devices include one primary network device and at least one secondary network device. For example, in a dual-connectivity scenario, a terminal can connect to one primary network device and one secondary network device. The primary network device can also be referred to as the master node (MN), and the secondary network device can also be referred to as the secondary node (SN); this application does not limit the names used. For ease of description, the following description uses the primary and secondary network devices as examples and should not be considered a limitation of this application.

[0057] In one possible implementation, dual connectivity can include Evolved Universal Terrestrial Radio Access and New Radio Dual Connectivity (E-UTRA-new radio dual connectivity, EN-DC), Next Generation Radio Access Network Evolved Universal Terrestrial Radio Access and New Radio Dual Connectivity (NG-RAN E-UTRA-NR dual connectivity, NGEN-DC), New Radio and Evolved Universal Terrestrial Radio Access Dual Connectivity (NR-E-UTRA dual connectivity, NE-DC), or New Radio and New Radio Dual Connectivity (NR-NR dual connectivity, NR-DC), etc. Specifically, EN-DC, i.e., LTE-NR DC, has an LTE base station as the primary network device connected to the 4G core network and an NR base station as the secondary network device. NGEN-DC has an LTE base station as the primary network device connected to the 5G core network and an NR base station as the secondary network device. NE-DC, i.e., NR-LTE DC, has an NR base station as the primary network device connected to the 5G core network and an LTE base station as the secondary network device. NR-DC, i.e., NR-NR DC, has both NR base stations as the primary and secondary network devices connected to the 5G core network. These are merely some possible examples; this application does not limit the type of the main network equipment and the auxiliary network equipment. For instance, at least one of the main network equipment and the auxiliary network equipment may be a base station for other future communication systems, such as a 6G base station.

[0058] Optionally, the primary network device and the secondary network device can be deployed at the same site, meaning they are the same network device. Alternatively, they can be deployed separately, meaning they are different network devices. This application does not limit the deployment method of the primary and secondary network devices.

[0059] In one possible implementation, the master network device can provide one or more cells to the terminal to form a master cell group (MCG). For example, a master cell group includes a master cell and zero or at least one secondary cell.

[0060] In one possible implementation, the secondary network device can provide one or more cells to the terminal, forming a secondary cell group (SCG). For example, a secondary cell group includes a primary secondary cell (PSCell) and zero or at least one secondary cell. A primary or secondary cell refers to the cell in which the terminal initiates a random access procedure at the secondary network device, or the cell in which the terminal skips the random access procedure and initiates data transmission during a change in the secondary network device, or the cell in the network device that initiates random access during a synchronization reconfiguration process.

[0061] III. Wake-up Receiver (WUR)

[0062] The concept of wake-up radio refers to the process where, when the main receiver (MR) of a terminal is in a powered-off or deep sleep state, the terminal's low-power wake-up receiver (LP-WUR) is activated to receive a wake-up signal, which can then be used to wake up the main receiver.

[0063] The main receiver can be used for data transmission, such as receiving downlink signaling and / or downlink data from network devices. In this application, the main receiver can be referred to as the first module. It is understood that the name "first module" is only for distinction and its specific name does not limit the scope of protection of this application. For example, the first module can also be a communication main module, main radio, or main circuit. For ease of explanation, the main receiver will be consistently described as the first module below.

[0064] A low-power wake-up receiver can be used to wake up the first module. In this application, the low-power wake-up receiver can be referred to as the second module. It is understood that the name "second module" is only for distinction and its specific name does not limit the scope of protection of this application. For example, the second module can also be a low-power wake-up circuit, a wake-up circuit, a communication auxiliary module, an auxiliary link, or an auxiliary circuit. For ease of explanation, the low-power wake-up receiver will be uniformly described as the second module below.

[0065] Generally, the first module may include a mid-frequency (RF) module and a baseband processing module, while the second module may include a simple receiver composed of the RF module, such as lower-power RF circuitry and baseband circuitry. As an example, the second module may not include a phase-locked loop (PLL) ring oscillator, but instead uses a low-noise amplifier (LNA) with a higher noise figure. As another example, the second module may be a sub-module (i.e., a partial module) of the first module, or may share some circuitry and components with the first module. Alternatively, compared to the first module, the second module may include fewer components. For example, the second module may not include a fast Fourier transform module, a complex channel decoding module, a low-density parity-check (LDPC) decoding module, or a polarization decoding module, and may have fewer registers and memory units, using a lower-bandwidth bus, thus consuming less power than the first module. Alternatively, the first module can also be considered the second module when it operates in a low-power mode. For example, if the first module reduces its operating voltage, disables some high-power functions, slows down the clock frequency, or reduces the sampling rate and bit width of analog-to-digital sampling, it is considered the second module.

[0066] The wake-up signal can be a signal with wake-up functionality, such as a signal used to wake up a single device or a group of devices, triggering the corresponding terminal to perform certain operations, including but not limited to at least one of updating system messages, receiving paging messages, initiating random access, and receiving disaster warning information. The wake-up signal can be a low-power wake-up signal (LP-WUS) or other signals with wake-up functionality; this application does not limit this. For example, in Figure 2 In this process, when the second module of the terminal detects a wake-up signal, it wakes up the first module, putting the first module into an on state so that it can perform data transmission. After the second module wakes up the first module, it can remain on or off, without limitation. When the first module completes data transmission, it can return to an idle state, that is, enter an ultra-low power state (ultra-deep sleep), also known as ultra-deep sleep mode, or even completely shut down to reduce power consumption. At this time, the second module can be powered on.

[0067] IV. Low-power signals

[0068] Low-power signals and non-low-power signals are relative terms.

[0069] For example, a low-power signal refers to one or more signals received on the second module for channel estimation, channel measurement, time-frequency synchronization, beam management, etc. For instance, a low-power signal could be a wake-up signal or a low-power synchronization signal (LP-SS).

[0070] For example, a non-low-power signal refers to one or more signals received on the first module for channel estimation, channel measurement, time-frequency synchronization, beam management, etc. For example, a non-low-power signal can be a synchronization signal block (SSB), a sounding reference signal (SRS), a tracking reference signal (TRS), a phase tracking reference signal (PTRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), or a positioning reference signal (PRS), etc., and this application does not limit it.

[0071] Alternatively, low-power signals can also be referred to as low-power measurement signals, and non-low-power signals can also be referred to as ordinary measurement signals. It should be noted that the terms low-power signals, low-power measurement signals, non-low-power signals, or ordinary measurement signals are merely names used for differentiation, and their specific names do not limit the scope of protection of this application.

[0072] In this application, a cell may provide low-power signals and / or non-low-power signals. Optionally, a cell providing low-power signals may be called an energy-saving cell, and a cell providing non-low-power signals may be called a normal cell. Optionally, energy-saving cells may also provide non-low-power signals, and normal cells may also provide low-power signals; this application does not limit this. For example, in... Figure 3 This can include multiple cells, such as the serving cell and neighboring cells. Among them, in Figure 3 In section 3-1, the serving cell provides a non-low-power signal, while neighboring cells provide a low-power signal. Figure 3 In 3-2, both the serving cell and neighboring cells provide non-low-power signals. Figure 3 In 3-3, both the serving cell and neighboring cells provide low-power signals. Figure 3 In cases 3-4, the serving cell provides low-power signals, while neighboring cells provide non-low-power signals.

[0073] V. Measurement Results

[0074] A measurement result mentioned in this application (such as the first measurement result, second measurement result, or third measurement result below) is a result obtained from measuring the signal quality or signal energy of a low-power signal or a non-low-power signal. For example, it may be one or more of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), received signal strength indicator (RSSI), and signal to interference plus noise ratio (SINR).

[0075] Generally, mobility management of terminals requires obtaining measurement results, and mobility management is then performed based on these results. However, even with the introduction of wake-up radio technology, how to perform mobility management remains a blank slate. Therefore, this application provides... Figure 4 The illustrated embodiments are provided to solve this problem. The embodiments of this application will be described in detail below. Figure 4 The image shows a communication method provided in an embodiment of this application. This method includes, but is not limited to, the following steps:

[0076] 401. The network device sends configuration information to the terminal. The configuration information includes at least the measurement object and the measurement events associated with the measurement object. The measurement object includes the first cell under the coverage of the network device, and the measurement events are used to trigger mobility management.

[0077] Accordingly, the terminal receives configuration information from the network device. This configuration information may be carried in RRC messages or in the medium access control-control element (MAC CE), and this application does not limit this.

[0078] 402. The terminal measures the first cell based on the low-power signal provided by the first cell to obtain a first measurement result, which is used to trigger a measurement event.

[0079] 403. The terminal sends a measurement report to the network device, and the measurement report indicates that a measurement event has been triggered.

[0080] Accordingly, the network device receives measurement reports from the terminal.

[0081] The specific implementation methods for steps 401 to 403 are explained below.

[0082] The measurement object can be a single cell or multiple cells covered by network equipment. The measurement events in step 402 above will be described below in conjunction with these two scenarios.

[0083] 1. The measurement object is a single cell covered by the network equipment, such as the first cell. In this case, the measurement event in step 402 above can represent the first measurement result being higher or lower than a certain threshold. For ease of distinction, the measurement event that 'represents the first measurement result being higher than a certain threshold' can be called the first measurement event, and the measurement event that 'represents the first measurement result being lower than a certain threshold' can be called the second measurement event. The specific naming does not limit the scope of protection of this application.

[0084] 1.1 The first measurement event indicates that the first measurement result is greater than the first threshold value of the first measurement event. In this case, the first cell can be the serving cell or a neighboring cell.

[0085] 1.1.1 The first cell is the serving cell. The first measurement event is triggered when the difference between the first measurement result and the first hysteresis value of the first measurement event is greater than a first threshold value. This is equivalent to the entering condition of the first measurement event being: Ms - Hys_1 > Thresh_1, where Ms is the first measurement result, Hys_1 is the first hysteresis value, and Thresh_1 is the first threshold value. Conversely, the first measurement event is stopped when the sum of the first measurement result and the first hysteresis value is less than the first threshold value. This is equivalent to the leaving condition of the first measurement event being: Ms + Hys_1. <Thresh_1。

[0086] Optionally, at least one of the first threshold value and the first hysteresis value can be notified to the terminal by the network device directly or indirectly, or it can be predefined. For example, at least one of the first threshold value and the first hysteresis value can be carried in the above configuration information, that is, the configuration information also includes at least one of the first threshold value and the first hysteresis value. This application does not limit this.

[0087] Optionally, a hysteresis value in this application (such as a first hysteresis value, a second hysteresis value, a third hysteresis value, or hysteresis value #a, etc.) can be an integer between 0 and 30, and its decibel (dB) value can be obtained by multiplying by 0.5. For example, if the first hysteresis value is 5, its dB value is 5 x 0.5 = 2.5 dB.

[0088] It should be noted that a measurement event mentioned in this application can correspond to an 'entry condition' and an 'exit condition'. Here, the 'entry condition' represents the condition that needs to be met to enter the measurement event, and the 'exit condition' represents the condition that needs to be met to exit the measurement event.

[0089] Optionally, if the first cell is the serving cell, since the first measurement event indicates that the first measurement result is greater than the first threshold value of the first measurement event, and the first measurement result is obtained by measuring the low-power signal provided by the first cell, the first measurement event can be regarded as the A1 event of the energy-saving cell.

[0090] Optionally, the threshold value for A1 events in energy-saving cells can be greater than, equal to, or less than the threshold value for A1 events in ordinary cells. An A1 event in an ordinary cell can indicate that the measurement result of a non-low-power signal provided by the serving cell is greater than the threshold value for A1 events in ordinary cells. When the threshold value for A1 events in energy-saving cells is greater than or less than the threshold value for A1 events in ordinary cells, independent threshold values ​​are achieved for A1 events in energy-saving cells and A1 events in ordinary cells. The purpose of this is twofold: firstly, because low-power signal measurement accuracy is low and deviates more from the true value, a more closely matched detection threshold is needed; secondly, for the entry conditions of A1 events in energy-saving cells, a threshold value that is less than the threshold value for A1 events in ordinary cells makes it easier for terminals to camp in energy-saving cells, achieving the goal of network energy saving.

[0091] 1.1.2. The first cell is a neighboring cell. The first measurement event is triggered when the value determined by the first measurement result, the frequency-level offset value #1 of the first cell, the cell-level offset value #1 of the first cell, and the second hysteresis value is greater than the first threshold. This is equivalent to the entry condition for the first measurement event being: Ms + Ofn + Ocn - Hys_2 > Thresh_2. Where Ms is the first measurement result, Ofn is the frequency-level offset value #1, Ocn is the cell-level offset value #1, Hys_2 is the second hysteresis value, and Thresh_2 is the first threshold. Conversely, if the value determined by the first measurement result, the frequency-level offset value #1, the cell-level offset value #1, and the second hysteresis value is less than the first threshold, the first measurement event is stopped. This is equivalent to the exit condition for the first measurement event being: Ms + Ofn + Ocn - Hys_2. <Thresh_2。

[0092] Optionally, at least one of the first threshold value, frequency-level offset value #1, cell-level offset value #1, and second hysteresis value can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the first threshold value, the frequency-level offset value #1, the cell-level offset value #1, and the second hysteresis value can be carried in the above configuration information, that is, the configuration information also includes at least one of the first threshold value, the frequency-level offset value #1, the cell-level offset value #1, and the second hysteresis value. This application does not limit this.

[0093] Optionally, at least one of the frequency-level offset value #1, cell-level offset value #1, and second hysteresis value can be a value greater than or equal to 0, and the application does not limit its size.

[0094] Optionally, if the difference between the first measurement result and the second hysteresis value of the first measurement event is greater than a first threshold value, the measurement report indicates that the first measurement event has been triggered. Thus, upon receiving the measurement report, the network device can determine that the terminal has requested a handover to the first cell.

[0095] Optionally, if the first cell is a neighboring cell, since the first measurement event indicates that the first measurement result is greater than the first threshold value of the first measurement event, and the first measurement result is obtained by measuring the low-power signal provided by the first cell, the first measurement event can be regarded as the A4 event of the energy-saving cell.

[0096] Optionally, the threshold value for the A4 event in an energy-saving cell can be greater than, equal to, or less than the threshold value for the A4 event in a normal cell. The A4 event in a normal cell can indicate that the measurement result of the non-low-power signal provided by the serving cell is less than this threshold value. When the threshold value for the A4 event in an energy-saving cell is greater than or less than the threshold value for the A4 event in a normal cell, independent threshold values ​​are achieved for the A4 events in energy-saving cells and those in normal cells. The purpose of this is that, because low-power signals have low measurement accuracy and deviate more from the true value, a more closely matched detection threshold is needed.

[0097] 1.2 The first measurement event indicates that the first measurement result is less than the second threshold value of the first measurement event. In this case, the first cell can be the serving cell.

[0098] Exemplarily, when the sum of the first measurement result and the third hysteresis value of the first measurement event is less than the second threshold value, the first measurement event is triggered. That is, the entry condition of the first measurement event is: Ms + Hys_3 < Thresh_3. Here, Ms is the first measurement result, Hys_3 is the third hysteresis value, and Thresh_3 is the second threshold value. On the contrary, when the difference between the first measurement result and the third hysteresis value is greater than the second threshold value, the first measurement event is stopped. That is, the departure condition of the first measurement event is: Ms - Hys_3 > Thresh_3.

[0099] Optionally, at least one of the second threshold value, the third hysteresis value, etc. can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the second threshold value, the third hysteresis value, etc. can be carried in the above configuration information, that is, the configuration information further includes at least one of the second threshold value, the third hysteresis value, etc. This application does not make any limitations in this regard.

[0100] Optionally, when the sum of the first measurement result and the third hysteresis value is less than the second threshold value, the measurement report indicates that the first measurement event is triggered. In this way, after receiving this measurement report, the network device can know that the first cell cannot continue to provide services for the terminal.

[0101] Optionally, in 1.2, because the first measurement event indicates that the first measurement result is less than the second threshold value of the first measurement event, and the first measurement result is obtained by measuring the low-power signal provided by the first cell, the first measurement event can be regarded as the A2 event of the energy-saving cell.

[0102] Optionally, the threshold value related to the A2 event of the energy-saving cell can be greater than, equal to, or less than the threshold value related to the A2 event of the ordinary cell. The A2 event of the ordinary cell can indicate that the measurement result of the non-low-power signal provided by the serving cell is less than the threshold value related to the A2 event of the ordinary cell. When the threshold value related to the A2 event of the energy-saving cell is greater than or less than the threshold value related to the A2 event of the ordinary cell, the A2 event of the energy-saving cell and the A2 event of the ordinary cell have independent threshold values. The purpose of doing this is: on the one hand, because the measurement accuracy of the low-power signal is low and deviates more from the true value, a more matching detection threshold is needed. On the other hand, for the entry condition of the A2 event of the energy-saving cell, the threshold value related to the A2 event of the energy-saving cell is less than the threshold value related to the A2 event of the ordinary cell, which can make it easier for the terminal to access the energy-saving cell and achieve the purpose of network energy saving. On the other hand, for the departure condition of the A2 event of the energy-saving cell, the threshold value related to the A2 event of the energy-saving cell is less than the threshold value related to the A2 event of the ordinary cell, which makes it easier for the terminal to switch to the energy-saving cell when it finds that the service quality of the serving cell has deteriorated, achieving the purpose of network energy saving.

[0103] 2. The measurement objects are multiple cells covered by the network equipment. For example, the multiple cells include a first cell and a second cell. That is, the terminal can also measure the second cell based on the low-power signal provided by the second cell to obtain a second measurement result. The first measurement result and the second measurement result are used to trigger the measurement event in step 402 above. In this case, the measurement event can be implemented in multiple ways. For ease of distinction, the measurement events involved in these implementations are named the third measurement event, the fourth measurement event, the fifth measurement event, and the sixth measurement event, respectively. Their specific naming does not limit the scope of protection of this application. Or, the multiple cells include a first cell and a third cell. That is, the terminal can also measure the third cell based on the non-low-power signal provided by the third cell to obtain a third measurement result. The first measurement result and the third measurement result are used to trigger the measurement event in step 402 above. In this case, the measurement event can be implemented in multiple ways. For ease of distinction, the measurement events involved in these implementations are named the seventh measurement event, the eighth measurement event, the ninth measurement event, and the tenth measurement event, respectively. Their specific naming does not limit the scope of protection of this application.

[0104] 2.1 A third measurement event indicates that the difference between the first and second measurement results is greater than the first bias value of the third measurement event. For example, when the first cell is a neighboring cell and the second cell is the serving cell, a third measurement event indicates that the difference between the first and second measurement results is greater than the first bias value.

[0105] As an example, the first bias value can be determined based on at least one of the frequency-level offset value #a of the first cell, the cell-level offset value #a of the first cell, the hysteresis value #a of the first cell, the frequency-level offset value #a of the second cell, the cell-level offset value #a of the second cell, and the offset value of the third measurement event. In this case, the first bias value satisfies the following condition: Ofp_a + Ocp_a + Off_a - Ofn_a - Ocn_a + Hys_a. Where, Ofn_a is the first frequency-level offset value, Ocn_a is the cell-level offset value #a of the first cell, Hys_a is the hysteresis value #a of the first cell, Ofp_a is the frequency-level offset value #a of the second cell, Ocp_a is the cell-level offset value #a of the second cell, and Off_a is the offset value of the third measurement event. That is, the entry condition for the third measurement event is: Mn_a - Mp_a > Ofp_a + Ocp_a + Off_a - Ofn_a - Ocn_a + Hys_a. Or it can be described as: Mn_a + Ofn_a + Ocn_a - Hys_a > Mp_a + Ofp_a + Ocp_a + Off_a. Mn_a is the first measurement result, and Mp_a is the second measurement result. Conversely, the departure condition for the third measurement event is: Mn_a - Mp_a < Ofp_a + Ocp_a + Off_a - Ofn_a - Ocn_a + Hys_a. Or it can be described as: Mn_a + Ofn_a + Ocn_a - Hys_a < Mp_a + Ofp_a + Ocp_a + Off_a.

[0106] Optionally, at least one of the frequency-level offset value #a of the first cell, the cell-level offset value #a of the first cell, the hysteresis value #a of the first cell, the frequency-level offset value #a of the second cell, the cell-level offset value #a of the second cell, and the offset value of the third measurement event can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the frequency-level offset value #a of the first cell, the cell-level offset value #a of the first cell, the hysteresis value #a of the first cell, the frequency-level offset value #a of the second cell, the cell-level offset value #a of the second cell, and the offset value of the third measurement event can be carried in the above configuration information, that is, the configuration information further includes at least one of the frequency-level offset value #a of the first cell, the cell-level offset value #a of the first cell, the hysteresis value #a of the first cell, the frequency-level offset value #a of the second cell, the cell-level offset value #a of the second cell, and the offset value of the third measurement event. This application does not limit this.

[0107] Optionally, at least one of the frequency-level offset value #a of the first cell, the cell-level offset value #a of the first cell, the frequency-level offset value #a of the second cell, the cell-level offset value #a of the second cell, and the offset value of the third measurement event, etc., can be a value greater than or equal to 0, and the size thereof is not limited in this application.

[0108] As another example, the first bias value can be determined based on at least one of the frequency-level offset value #a of the first cell, the cell-level offset value #a of the first cell, the hysteresis value #a of the first cell, the frequency-level offset value #a of the second cell, the cell-level offset value #a of the second cell, the offset value of the third measurement event, and the additional offset value of the third measurement event, etc. In this case, the first bias value satisfies the following condition: Ofp_a + Ocp_a + Off_a + Additional_Offset_a - Ofn_a - Ocn_a + Hys_a. Where, Additional_Offset_a is the additional offset value of the third measurement event. That is, the entry condition of the third measurement event is: Mn_a - Mp_a > Ofp_a + Ocp_a + Off_a + Additional_Offset_a - Ofn_a - Ocn_a + Hys_a. Or it can be described as: Mn_a + Ofn_a + Ocn_a - Hys_a > Mp_a + Ofp_a + Ocp_a + Off_a + Additional_Offset_a. On the contrary, the departure condition of the third measurement event is: Mn_a - Mp_a < Ofp_a + Ocp_a + Off_a + Additional_Offset_a - Ofn_a - Ocn_a + Hys_a. Or it can be described as: Mn_a + Ofn_a + Ocn_a - Hys_a < Mp_a + Ofp_a + Ocp_a + Off_a + Additional_Offset_a.

[0109] Optionally, when the first cell is a neighbor cell, since the third measurement event indicates that the difference between the first measurement result and the second measurement result is greater than the first bias value, and the first measurement result is obtained by measuring the low-power signal provided by the first cell, the third measurement event can be regarded as the A3 event of the energy-saving cell.

[0110] In a possible implementation manner, the value of the parameter involved in the A3 event of the energy-saving cell can be greater than, equal to, or less than the value of the corresponding parameter involved in the A3 event of the ordinary cell. The A3 event of the ordinary cell can indicate that the difference between the measurement result of the non-low-power signal provided by the neighbor cell and the measurement result of the non-low-power signal provided by the serving cell is greater than the corresponding bias value.

[0111] For example, the frequency level offset value of the neighboring cells involved in the A3 event of an energy-saving cell can be greater than, equal to or less than the frequency level offset value of the neighboring cells involved in the A3 event of an ordinary cell. The cell-level offset value of the neighboring cells involved in the A3 event of an energy-saving cell can be greater than, equal to or less than the cell-level offset value of the neighboring cells involved in the A3 event of an ordinary cell. The other parameters are similar and will not be elaborated here.

[0112] For example, the frequency level offset of neighboring cells involved in the A3 event of an energy-saving cell is greater than that involved in the A3 event of a normal cell, while the frequency level offset of neighboring cells involved in the A3 event of a normal cell is 0. This has two advantages: firstly, because low-power signals have lower measurement accuracy and deviate more from the true value, more matching parameter values ​​can be obtained. Secondly, the entry conditions for the A3 event of an energy-saving cell make it easier for terminals to access the energy-saving cell, achieving network energy saving. Thirdly, the departure conditions for the A3 event of an energy-saving cell make it easier for terminals to switch to the energy-saving cell when they detect a decline in the service quality of the serving cell, achieving network energy saving.

[0113] For example, the cell-level offset value of neighboring cells involved in the A3 event of an energy-saving cell is greater than that of neighboring cells involved in the A3 event of a normal cell, while the cell-level offset value of neighboring cells involved in the A3 event of a normal cell is 0. Thus, on the one hand, because low-power signals have lower measurement accuracy and deviate more from the true value, more matching parameter values ​​can be obtained. On the other hand, the entry conditions for the A3 event of an energy-saving cell make it easier for terminals to access the energy-saving cell, achieving the goal of network energy saving. Furthermore, the departure conditions for the A3 event of an energy-saving cell make it easier for terminals to switch to the energy-saving cell when they detect a decline in the service quality of the serving cell, achieving the goal of network energy saving.

[0114] For example, the cell-level offset value of the serving cell involved in the A3 event of an energy-saving cell is smaller than that of the serving cell involved in the A3 event of a normal cell, and the cell-level offset value of the serving cell involved in the A3 event of an energy-saving cell is 0. This has two advantages: firstly, because low-power signals have lower measurement accuracy and deviate more from the true value, more matching parameter values ​​can be obtained. Secondly, the entry conditions for the A3 event of an energy-saving cell make it easier for terminals to access the energy-saving cell, achieving network energy saving. Thirdly, the departure conditions for the A3 event of an energy-saving cell make it easier for terminals to switch to the energy-saving cell when they detect a decline in the service quality of the serving cell, achieving network energy saving.

[0115] In another possible implementation, compared with the A3 event of a normal cell, a parameter can be added to the entry condition or exit condition of the A3 event of an energy-saving cell. For example, an additional offset value. That is, the entry condition of the A3 event of the energy-saving cell is: Mn + Ofn + Ocn - Hys > Mp + Ofp + Ocp + Off + Additional_Offset, while the entry condition of the A3 event of the normal cell is: Mn + Ofn + Ocn - Hys > Mp + Ofp + Ocp + Off. Conversely, the exit condition of the A3 event of the energy-saving cell is: Mn + Ofn + Ocn - Hys < Mp + Ofp + Ocp + Off + Additional_Offset, while the exit condition of the A3 event of the normal cell is: Mn + Ofn + Ocn - Hys < Mp + Ofp + Ocp + Off. Here, the meanings of each parameter such as Mn and Ofn are similar to those involved in the entry condition of the third measurement event and will not be elaborated here. In this way, on the one hand, for the entry condition of the A3 event of the energy-saving cell, it can make it easier for the terminal to access the energy-saving cell, achieving the purpose of network energy saving. On the other hand, for the exit condition of the A3 event of the energy-saving cell, when the terminal finds that the service quality of the serving cell has deteriorated, it is easier to switch to the energy-saving cell, achieving the purpose of network energy saving.

[0116] 2.2. The fourth measurement event indicates that the difference between the second measurement result and the first measurement result is greater than the second offset value of the fourth measurement event. For example, when the first cell is the serving cell and the second cell is the neighboring cell, the fourth measurement event indicates that the difference between the second measurement result and the first measurement result is greater than the second offset value. Optionally, the first cell and the second cell can be co-frequency cells or inter-frequency cells.

[0117] As an example, the second offset value can be determined based on at least one of the frequency-level offset value #b of the first cell, the cell-level offset value #b of the first cell, the hysteresis value #b of the first cell, the frequency-level offset value #b of the second cell, the cell-level offset value #b of the second cell, and the offset value of the fourth measurement event, etc. The following introduces how to determine the second offset value.

[0118] Exemplarily, the second bias value satisfies the following condition: Ofp_b + Ocp_b + Off_b - Ofn_b - Ocn_b + Hys_b. Where, Ofn_b is the frequency-level offset value of the second frequency level, Ocn_b is the cell-level offset value of the first cell #b, Hys_b is the hysteresis value #b, Ofp_b is the frequency-level offset value of the second cell #b, Ocp_b is the cell-level offset value of the second cell #b, and Off_b is the offset value of the fourth measurement event. That is, the entry condition for the fourth measurement event is: Mn_b - Mp_b > Ofp_b + Ocp_b + Off_b - Ofn_b - Ocn_b + Hys_b. Or it can be described as: Mn_b + Ofn_b + Ocn_b - Hys_b > Mp_b + Ofp_b + Ocp_b + Off_b. Where, Mn_b is the second measurement result and Mp_b is the first measurement result. Conversely, the departure condition for the third measurement event is: Mn_b - Mp_b < Ofp_b + Ocp_b + Off_b - Ofn_b - Ocn_b + Hys_b. Or it can be described as: Mn_b + Ofn_b + Ocn_b - Hys_b < Mp_b + Ofp_b + Ocp_b + Off_b.

[0119] Optionally, at least one of the frequency-level offset value #b of the first cell, the cell-level offset value #b of the first cell, the hysteresis value #b of the first cell, the frequency-level offset value #b of the second cell, the cell-level offset value #b of the second cell, and the offset value of the fourth measurement event, etc. can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the frequency-level offset value #b of the first cell, the cell-level offset value #b of the first cell, the hysteresis value #b of the first cell, the frequency-level offset value #b of the second cell, the cell-level offset value #b of the second cell, and the offset value of the fourth measurement event, etc. can be carried in the above configuration information, that is, the configuration information further includes at least one of the frequency-level offset value #b of the first cell, the cell-level offset value #b of the first cell, the hysteresis value #b of the first cell, the frequency-level offset value #b of the second cell, the cell-level offset value #b of the second cell, and the offset value of the fourth measurement event, etc. This application does not make any limitations on this.

[0120] Optionally, at least one of the frequency-level offset value #b of the first cell, the cell-level offset value #b of the first cell, the frequency-level offset value #b of the second cell, the cell-level offset value #b of the second cell, and the offset value of the fourth measurement event, etc. can be a value greater than or equal to 0. This application does not limit its size.

[0121] As an example, the second bias value can be determined based on at least one of the frequency-level offset value #b of the first cell, the cell-level offset value #b of the first cell, the hysteresis value #b of the first cell, the frequency-level offset value #b of the second cell, the cell-level offset value #b of the second cell, the offset value of the fourth measurement event, and the additional offset value of the fourth measurement event. How to determine the second bias value will be introduced below.

[0122] Exemplarily, the second bias value satisfies the following condition: Ofp_b+Ocp_b+Off_b+Additional_Offset_b-Ofn_b-Ocn_b+Hys_b. Where, Additional_Offset_b is the additional offset value of the fourth measurement event. That is, the entry condition of the fourth measurement event is: Mn_b-Mp_b>Ofp_b+Ocp_b+Off_b+Additional_Offset_b-Ofn_b-Ocn_b+Hys_b. Or it can be described as: Mn_b+Ofn_b+Ocn_b-Hys_b>Mp_b+Ofp_b+Ocp_b+Off_b+Additional_Offset_b. Conversely, the departure condition of the third measurement event is: Mn_b-Mp_b<Ofp_b+Ocp_b+Off_b+Additional_Offset_b-Ofn_b-Ocn_b+Hys_b. Or it can be described as: Mn_b+Ofn_b+Ocn_b-Hys_b<Mp_b+Ofp_b+Ocp_b+Off_b+Additional_Offset_b.

[0123] Optionally, when the second cell is a neighbor cell, since the fourth measurement event indicates that the difference between the second measurement result and the first measurement result is greater than the second bias value, and the second measurement result is obtained by measuring the low-power signal provided by the second cell, the fourth measurement event can be regarded as the A3 event of the energy-saving cell.

[0124] 2.3. The fifth measurement event indicates that the first measurement result is greater than the third threshold value corresponding to the first cell in the fifth measurement event, and the second measurement result is less than the fourth threshold value corresponding to the second cell in the fifth measurement event. For example, when the first cell is a neighbor cell and the second cell is a serving cell, the fifth measurement event indicates that the first measurement result is greater than the third threshold value and the second measurement result is less than the fourth threshold value.

[0125] Specifically, a fifth measurement event is triggered when the first measurement result is greater than the third threshold and the second measurement result is less than the fourth threshold. For example, if the value determined based on the first measurement result, the frequency level offset value #A of the first cell, and the hysteresis value #A1 of the first cell is greater than the third threshold, and the value based on the second measurement result and the hysteresis value #A2 of the second cell is less than the fourth threshold, the fifth measurement event is triggered. This is equivalent to the entry condition for the fifth measurement event being: Mn_A + Ofn_A + Ocn_A + Hys_A1<Thresh_A1,Mp_A-Hys_A2> Thresh_A2. Where Mn_A is the first measurement result, Ofn_A is the frequency level offset value #A of the first cell, Ocn_A is the hysteresis value #A1 of the first cell, and Thresh_A1 is the third threshold value. Mp_A is the second measurement result, Hys_A2 is the hysteresis value #A2 of the second cell, and Thresh_A2 is the fourth threshold value. Conversely, if the first measurement result is less than the third threshold value and the second measurement result is greater than the fourth threshold value, the fifth measurement event is stopped. For example, if the value determined based on the first measurement result, the frequency level offset value #A of the first cell, and the hysteresis value #A1 of the first cell is less than the third threshold value, and the value determined based on the second measurement result and the hysteresis value #A2 of the second cell is greater than the fourth threshold value, the fifth measurement event is stopped. This is equivalent to the departure condition of the fifth measurement event being: Mn_A + Ofn_A + Ocn_A + Hys_A1 > Thresh_A1, Mp_A - Hys_A2 <Thresh_A2。

[0126] Optionally, at least one of the third threshold value, the frequency level offset value #A of the first cell, the hysteresis value #A1 of the first cell, the fourth threshold value, and the hysteresis value #A2 of the second cell can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the third threshold value, the frequency level offset value #A of the first cell, the hysteresis value #A1 of the first cell, the fourth threshold value, and the hysteresis value #A2 of the second cell can be carried in the above configuration information, that is, the configuration information also includes at least one of the third threshold value, the frequency level offset value #A of the first cell, the hysteresis value #A1 of the first cell, the fourth threshold value, and the hysteresis value #A2 of the second cell. This application does not limit this.

[0127] Optionally, at least one of the frequency level offset value #A of the first cell, the hysteresis value #A1 of the first cell, and the hysteresis value #A2 of the second cell can be a value greater than or equal to 0, and the application does not limit its size.

[0128] Optionally, if the first cell is a neighboring cell, since the fifth measurement event indicates that the first measurement result is greater than the third threshold and the second measurement result is less than the fourth threshold, and the first measurement result is obtained by measuring the low-power signal provided by the first cell, the fifth measurement event can be regarded as the A5 event of the energy-saving cell.

[0129] Optionally, the values ​​of the parameters involved in the A5 event of an energy-saving cell can be greater than, equal to, or less than the values ​​of the corresponding parameters involved in the A5 event of a normal cell. For details, please refer to the description of the A3 event above, which will not be repeated here. Specifically, the A5 event of a normal cell can indicate that the measurement result of the non-low-power signal provided by a neighboring cell is greater than a threshold value, while the measurement result of the non-low-power signal provided by the serving cell is less than another threshold value.

[0130] 2.4 The sixth measurement event indicates that the first measurement result is less than the fifth threshold value corresponding to the first cell in the sixth measurement event, and the second measurement result is greater than the sixth threshold value corresponding to the second cell in the sixth measurement event. For example, if the first cell is the serving cell and the second cell is a neighboring cell, the sixth measurement event indicates that the first measurement result is less than the fifth threshold value, and the second measurement result is greater than the sixth threshold value.

[0131] The sixth measurement event is triggered when the first measurement result is less than the fifth threshold and the second measurement result is greater than the sixth threshold. For example, the sixth measurement event is triggered when the value determined based on the first measurement result and the hysteresis value #B1 of the first cell is less than the fifth threshold, and the value determined based on the second measurement result, the frequency level offset value #B of the second cell, and the hysteresis value #B2 of the second cell is greater than the sixth threshold. This is equivalent to the entry condition for the sixth measurement event being: Mp_B - Hys_B1.<Thresh_B2,Mn_B+Ofn_B+Ocn_B+Hys_B2> Thresh_B2. Where Mp_B is the first measurement result, Hys_B1 is the hysteresis value #B1 of the first cell, and Thresh_B1 is the sixth threshold. Mn_B is the second measurement result, Ofn_B is the frequency level offset value #B of the second cell, Ocn_B is the hysteresis value #B2 of the second cell, and Thresh_B2 is the sixth threshold. Conversely, if the first measurement result is greater than the fifth threshold and the second measurement result is less than the sixth threshold, the sixth measurement event is stopped. For example, if the value determined based on the first measurement result and the hysteresis value #B1 of the first cell is greater than the fifth threshold, and the value determined based on the second measurement result, the frequency level offset value #B of the second cell, and the hysteresis value #B2 of the second cell is less than the sixth threshold, the sixth measurement event is stopped. This is equivalent to the departure condition for the sixth measurement event being: Mp_B - Hys_B1 > Thresh_B2, Mn_B + Ofn_B + Ocn_B + Hys_B2. <Thresh_B2。

[0132] Optionally, at least one of the fifth threshold value, the hysteresis value #B1 of the first cell, the sixth threshold value, the frequency level offset value #B of the second cell, and the hysteresis value #B2 of the second cell can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the fifth threshold value, the hysteresis value #B1 of the first cell, the sixth threshold value, the frequency level offset value #B of the second cell, and the hysteresis value #B2 of the second cell can be carried in the above configuration information, that is, the configuration information also includes at least one of the fifth threshold value, the hysteresis value #B1 of the first cell, the sixth threshold value, the frequency level offset value #B of the second cell, and the hysteresis value #B2 of the second cell. This application does not limit this.

[0133] Optionally, at least one of the hysteresis value #B1 of the first cell, the frequency level offset value #B of the second cell, and the hysteresis value #B2 of the second cell can be a value greater than or equal to 0, and this application does not limit its size.

[0134] Optionally, if the second cell is a neighboring cell, since the sixth measurement event indicates that the first measurement result is less than the fifth threshold and the second measurement result is greater than the sixth threshold, and the second measurement result is obtained by measuring the low-power signal provided by the second cell, the sixth measurement event can be regarded as the A5 event of the energy-saving cell.

[0135] 2.5 The seventh measurement event indicates that the difference between the first and third measurement results is greater than the third bias value of the seventh measurement event. For example, when the first cell is a neighboring cell and the third cell is the serving cell, the seventh measurement event indicates that the difference between the first and third measurement results is greater than the third bias value.

[0136] As an example, the third offset value can be determined based on at least one of the following: the frequency-level offset value #c of the first cell, the cell-level offset value #c of the first cell, the hysteresis value #c of the first cell, the frequency-level offset value #c of the third cell, the cell-level offset value #c of the third cell, and the offset value of the seventh measurement event. The method for determining the third offset value is described below.

[0137] Exemplarily, the third bias value satisfies the following condition: Ofp_c + Ocp_c + Off_c - Ofn_c - Ocn_c + Hys_c. Where, Ofn_c is the frequency-level offset value of the first frequency level, Ocn_c is the cell-level offset value #c of the first cell, Hys_c is the hysteresis value #c of the first cell, Ofp_c is the frequency-level offset value #c of the third cell, Ocp_c is the cell-level offset value #c of the third cell, and Off_c is the offset value of the seventh measurement event. That is to say, the entry condition of the seventh measurement event is: Mn_c - Mp_c > Ofp_c + Ocp_c + Off_c - Ofn_c - Ocn_c + Hys_c. Or it can be described as: Mn_c + Ofn_c + Ocn_c - Hys_c > Mp_c + Ofp_c + Ocp_c + Off_c. Where, Mn_c is the first measurement result and Mp_c is the third measurement result. Conversely, the departure condition of the seventh measurement event is: Mn_c - Mp_c < Ofp_c + Ocp_c + Off_c - Ofn_c - Ocn_c + Hys_c. Or it can be described as: Mn_c + Ofn_c + Ocn_c - Hys_c < Mp_c + Ofp_c + Ocp_c + Off_c.

[0138] Optionally, at least one of the frequency-level offset value #c of the first cell, the cell-level offset value #c of the first cell, the hysteresis value #c of the first cell, the frequency-level offset value #c of the third cell, the cell-level offset value #c of the third cell, and the offset value of the seventh measurement event, etc. can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the frequency-level offset value #c of the first cell, the cell-level offset value #c of the first cell, the hysteresis value #c of the first cell, the frequency-level offset value #c of the third cell, the cell-level offset value #c of the third cell, and the offset value of the seventh measurement event, etc. can be carried in the above configuration information, that is, the configuration information further includes at least one of the frequency-level offset value #c of the first cell, the cell-level offset value #c of the first cell, the hysteresis value #c of the first cell, the frequency-level offset value #c of the third cell, the cell-level offset value #c of the third cell, and the offset value of the seventh measurement event, etc. This application does not make any limitations on this.

[0139] Optionally, at least one of the frequency-level offset value #c of the first cell, the cell-level offset value #c of the first cell, the frequency-level offset value #c of the third cell, the cell-level offset value #c of the third cell, and the offset value of the seventh measurement event, etc. can be a value greater than or equal to 0, and this application does not limit its size.

[0140] As another example, the third bias value can be determined based on at least one of the frequency-level offset value #c of the first cell, the cell-level offset value #c of the first cell, the hysteresis value #c of the first cell, the frequency-level offset value #c of the third cell, the cell-level offset value #c of the third cell, the offset value of the seventh measurement event, and the additional offset value of the seventh measurement event, etc. The following introduces how to determine the third bias value.

[0141] Exemplarily, the third bias value satisfies the following condition: Ofp_c + Ocp_c + Off_c + Cdditioncl_Offset_c - Ofn_c - Ocn_c + Hys_c. Where, Additioncl_Offset_c is the additional offset value of the seventh measurement event. That is, the entry condition of the seventh measurement event is: Mn_c - Mp_c > Ofp_c + Ocp_c + Off_c + Additioncl_Offset_c - Ofn_c - Ocn_c + Hys_c. Or it can be described as: Mn_c + Ofn_c + Ocn_c - Hys_c > Mp_c + Ofp_c + Ocp_c + Off_c + Additioncl_Offset_c. Conversely, the departure condition of the seventh measurement event is: Mn_c - Mp_c < Ofp_c + Ocp_c + Off_c + Additioncl_Offset_c - Ofn_c - Ocn_c + Hys_c. Or it can be described as: Mn_c + Ofn_c + Ocn_c - Hys_c < Mp_c + Ofp_c + Ocp_c + Off_c + Additioncl_Offset_c.

[0142] Optionally, when the first cell is a neighbor cell, since the seventh measurement event indicates that the difference between the first measurement result and the third measurement result is greater than the third bias value, and the first measurement result is obtained by measuring the low-power signal provided by the first cell, the seventh measurement event can be regarded as the A3 event of the energy-saving cell.

[0143] 2.6. The eighth measurement event indicates that the difference between the third measurement result and the first measurement result is greater than the fourth bias value of the eighth measurement event. For example, when the first cell is the serving cell and the third cell is the neighbor cell, the eighth measurement event indicates that the difference between the third measurement result and the first measurement result is greater than the fourth bias value.

[0144] As an example, the fourth bias value can be determined based on at least one of the frequency-level offset value #d of the first cell, the cell-level offset value #d of the first cell, the hysteresis value #d of the first cell, the frequency-level offset value #d of the third cell, the cell-level offset value #d of the third cell, and the offset value of the eighth measurement event, etc. The following introduces how to determine the fourth bias value.

[0145] Exemplarily, the fourth offset value satisfies the following condition: Ofp_d + Ocp_d + Off_d - Ofp_d - Ocn_d + Hys_d. Where, Ofp_d is the frequency-level offset value of the first frequency level, Ocn_d is the cell-level offset value #d of the first cell, Hys_d is the hysteresis value #d of the first cell, Ofp_d is the frequency-level offset value #d of the third cell, Ocp_d is the cell-level offset value #d of the third cell, and Off_d is the offset value of the eighth measurement event. That is, the entry condition for the eighth measurement event is: Mn_d - Mp_d > Ofp_d + Ocp_d + Off_d - Ofp_d - Ocn_d + Hys_d. Or it can be described as: Mn_d + Ofp_d + Ocn_d - Hys_d > Mp_d + Ofp_d + Ocp_d + Off_d. Mn_d is the third measurement result, and Mp_d is the first measurement result. Conversely, the departure condition for the eighth measurement event is: Mn_d - Mp_d < Ofp_d + Ocp_d + Off_d - Ofp_d - Ocn_d + Hys_d. Or it can be described as: Mn_d + Ofp_d + Ocn_d - Hys_d < Mp_d + Ofp_d + Ocp_d + Off_d.

[0146] Optionally, at least one of the frequency-level offset value #d of the first cell, the cell-level offset value #d of the first cell, the hysteresis value #d of the first cell, the frequency-level offset value #d of the third cell, the cell-level offset value #d of the third cell, and the offset value of the eighth measurement event, etc. can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the frequency-level offset value #d of the first cell, the cell-level offset value #d of the first cell, the hysteresis value #d of the first cell, the frequency-level offset value #d of the third cell, the cell-level offset value #d of the third cell, and the offset value of the eighth measurement event, etc. can be carried in the above configuration information, that is, the configuration information further includes at least one of the frequency-level offset value #d of the first cell, the cell-level offset value #d of the first cell, the hysteresis value #d of the first cell, the frequency-level offset value #d of the third cell, the cell-level offset value #d of the third cell, and the offset value of the eighth measurement event, etc. This application does not make any limitations in this regard.

[0147] Optionally, at least one of the frequency-level offset value #d of the first cell, the cell-level offset value #d of the first cell, the frequency-level offset value #d of the third cell, the cell-level offset value #d of the third cell, and the offset value of the eighth measurement event, etc. can be a value greater than or equal to 0, and this application does not limit its size.

[0148] As another example, the fourth bias value can be determined based on at least one of the frequency-level offset value #d of the first cell, the cell-level offset value #d of the first cell, the hysteresis value #d of the first cell, the frequency-level offset value #d of the third cell, the cell-level offset value #d of the third cell, the offset value of the eighth measurement event, and the additional offset value of the eighth measurement event. How to determine the fourth bias value will be introduced below.

[0149] Exemplarily, the fourth bias value satisfies the following condition: Ofp_d + Ocp_d + Off_d + Additiondl_Offset_d - Ofp_d - Ocn_d + Hys_d. Where, Additiondl_Offset_d is the additional offset value of the eighth measurement event. That is, the entry condition of the eighth measurement event is: Mn_d - Mp_d > Ofp_d + Ocp_d + Off_d + Additiondl_Offset_d - Ofp_d - Ocn_d + Hys_d. Or it can be described as: Mn_d + Ofp_d + Ocn_d - Hys_d > Mp_d + Ofp_d + Ocp_d + Off_d + Additiondl_Offset_d. Conversely, the exit condition of the eighth measurement event is: Mn_d - Mp_d < Ofp_d + Ocp_d + Off_d + Additiondl_Offset_d - Ofp_d - Ocn_d + Hys_d. Or it can be described as: Mn_d + Ofp_d + Ocn_d - Hys_d < Mp_d + Ofp_d + Ocp_d + Off_d + Additiondl_Offset_d.

[0150] Optionally, when the third cell is a neighbor cell, since the eighth measurement event indicates that the difference between the third measurement result and the first measurement result is greater than the fourth bias value, and the third measurement result is obtained by measuring the non-low-power signal provided by the third cell, the eighth measurement event can be regarded as the A3 event of an ordinary cell.

[0151] 2.7. The ninth measurement event indicates that the first measurement result is greater than the seventh threshold value corresponding to the first cell in the ninth measurement event, and the third measurement result is less than the eighth threshold value corresponding to the third cell in the ninth measurement event. For example, when the first cell is a neighbor cell and the third cell is a serving cell, the ninth measurement event indicates that the first measurement result is greater than the seventh threshold value and the third measurement result is less than the eighth threshold value.

[0152] Specifically, a ninth measurement event is triggered when the first measurement result is greater than the seventh threshold and the third measurement result is less than the eighth threshold. For example, a ninth measurement event is triggered when the value determined based on the first measurement result, the frequency level offset value #C of the first cell, and the hysteresis value #C1 of the first cell is greater than the seventh threshold, and the value determined based on the third measurement result and the hysteresis value #C2 of the third cell is less than the eighth threshold. This is equivalent to the entry condition for the ninth measurement event being: Mn_C + Ofn_C + Ocn_C + Hys_C1.<Thresh_C1,Mp_C-Hys_C2> Thresh_C2. Where Mn_C is the first measurement result, Ofn_C is the frequency level offset value #C of the first cell, Ocn_C is the hysteresis value #C1 of the first cell, and Thresh_C1 is the seventh threshold value. Mp_C is the third measurement result, Hys_C2 is the hysteresis value #C2 of the third cell, and Thresh_C2 is the eighth threshold value. Conversely, if the first measurement result is less than the seventh threshold value and the third measurement result is greater than the eighth threshold value, the ninth measurement event is stopped. For example, if the value determined based on the first measurement result, the frequency level offset value #C of the first cell, and the hysteresis value #C1 of the first cell is less than the seventh threshold value, and the value determined based on the third measurement result and the hysteresis value #C2 of the third cell is greater than the eighth threshold value, the ninth measurement event is stopped. This is equivalent to the departure condition of the ninth measurement event being: Mn_C + Ofn_C + Ocn_C + Hys_C1 > Thresh_C1, Mp_C - Hys_C2. <Thresh_C2。

[0153] Optionally, at least one of the seventh threshold value, the frequency level offset value #C of the first cell, the hysteresis value #C1 of the first cell, the eighth threshold value, and the hysteresis value #C2 of the third cell can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the seventh threshold value, the frequency level offset value #C of the first cell, the hysteresis value #C1 of the first cell, the eighth threshold value, and the hysteresis value #C2 of the third cell can be carried in the above configuration information, that is, the configuration information also includes at least one of the seventh threshold value, the frequency level offset value #C of the first cell, the hysteresis value #C1 of the first cell, the eighth threshold value, and the hysteresis value #C2 of the third cell. This application does not limit this.

[0154] Optionally, at least one of the frequency level offset value #C of the first cell, the hysteresis value #C1 of the first cell, and the hysteresis value #C2 of the third cell can be a value greater than or equal to 0, and the application does not limit its size.

[0155] Optionally, if the first cell is a neighboring cell, since the ninth measurement event indicates that the first measurement result is greater than the seventh threshold and the third measurement result is less than the eighth threshold, and the third measurement result is obtained by measuring the low-power signal provided by the first cell, the ninth measurement event can be regarded as the A5 event of the energy-saving cell.

[0156] 2.8 The tenth measurement event indicates that the first measurement result is less than the ninth threshold value corresponding to the first cell in the tenth measurement event, and the third measurement result is greater than the tenth threshold value corresponding to the third cell in the tenth measurement event. For example, if the first cell is the serving cell and the third cell is a neighboring cell, the tenth measurement event indicates that the first measurement result is less than the ninth threshold value, and the third measurement result is greater than the tenth threshold value.

[0157] The tenth measurement event is triggered when the first measurement result is less than the ninth threshold and the third measurement result is greater than the tenth threshold. For example, the tenth measurement event is triggered when the value determined based on the first measurement result and the hysteresis value #D1 of the first cell is less than the ninth threshold, and the value determined based on the third measurement result, the frequency level offset value #D of the third cell, and the hysteresis value #D2 of the third cell is greater than the tenth threshold. This is equivalent to the entry condition for the tenth measurement event being: Mp_D - Hys_D1.<Thresh_D2,Mn_D+Ofn_D+Ocn_D+Hys_D2> Thresh_D2. Where Mp_D is the first measurement result, Hys_D1 is the hysteresis value #D1 of the first cell, and Thresh_D1 is the tenth threshold. Mn_D is the third measurement result, Ofn_D is the frequency level offset value #D of the third cell, Ocn_D is the hysteresis value #D2 of the third cell, and Thresh_D2 is the tenth threshold. Conversely, the tenth measurement event is stopped if the first measurement result is greater than the ninth threshold and the third measurement result is less than the tenth threshold. For example, if the value determined based on the first measurement result and the hysteresis value #D1 of the first cell is greater than the ninth threshold, and the value determined based on the third measurement result, the frequency level offset value #D of the third cell, and the hysteresis value #D2 of the third cell is less than the tenth threshold, the tenth measurement event is stopped. This is equivalent to the departure condition for the tenth measurement event being: Mp_D - Hys_D1 > Thresh_D2, Mn_D + Ofn_D + Ocn_D + Hys_D2. <Thresh_D2。

[0158] Optionally, at least one of the following: the ninth threshold value, the hysteresis value #D1 of the first cell, the tenth threshold value, the frequency level offset value #D of the third cell, and the hysteresis value #D2 of the third cell, can be notified to the terminal by the network device directly or indirectly, or predefined. For example, at least one of the following: the ninth threshold value, the hysteresis value #D1 of the first cell, the tenth threshold value, the frequency level offset value #D of the third cell, and the hysteresis value #D2 of the third cell, can be carried in the above configuration information; that is, the configuration information also includes at least one of the following: the ninth threshold value, the hysteresis value #D1 of the first cell, the tenth threshold value, the frequency level offset value #D of the third cell, and the hysteresis value #D2 of the third cell. This application does not limit this.

[0159] Optionally, at least one of the hysteresis value #D1 of the first cell, the frequency level offset value #D of the third cell, and the hysteresis value #D2 of the third cell can be a value greater than or equal to 0, and the application does not limit its size.

[0160] Optionally, if the third cell is a neighboring cell, since the tenth measurement event indicates that the first measurement result is less than the ninth threshold and the third measurement result is greater than the tenth threshold, and the third measurement result is obtained by measuring the non-low power signal provided by the third cell, the tenth measurement event can be regarded as the A5 event of a normal cell.

[0161] Optionally, the first cell and the second cell involved in any of 2.1, 2.2, 2.5, and 2.6 above can be co-frequency cells or inter-frequency cells.

[0162] Optionally, the serving cell or neighboring cell mentioned in 1 or 2 above can be replaced with other cells. For example, the serving cell mentioned in any of 2.1, 2.2, 2.5, and 2.6 can be replaced with other cells, such as secondary cells, etc., without limitation. In the case where the serving cell mentioned in any of 2.1, 2.2, 2.5, and 2.6 above is replaced with a secondary cell, the corresponding measurement event can be regarded as an A6 event.

[0163] The entry condition for event A6 is: Mn_e + Ocn_e - Hys_e > Ms + Ocs + Off_e. Here, Mn_e is the result of measuring the low-power or non-low-power signal provided by the neighboring cell, Ocn_e is the cell-level offset value of the neighboring cell, Hys_e is the hysteresis value of the neighboring cell, Ms is the result of measuring the low-power or non-low-power signal provided by the secondary cell, Ocs is the cell-level offset value of the secondary cell, and Off_e is the offset value of event A6. Conversely, the exit condition for event A6 is: Mn_e + Ocn_e - Hys_e. <Ms+Ocs+Off_e。

[0164] Optionally, the A6 event can be either the A6 event of an energy-saving community or the A5 event of a regular community. Optionally, the value of the parameter involved in the A6 event of an energy-saving community can be greater than, equal to, or less than the value of the corresponding parameter involved in the A6 event of a regular community. For details, please refer to the description of the corresponding A3 event above, which will not be repeated here.

[0165] The following describes the mobility management triggered by each measurement event. Specifically, if the first cell is the serving cell, the mobility management triggered by the first measurement event can be to continue camping on the serving cell. If the first cell is a neighboring cell, the mobility management triggered by the first measurement event can be to hand over to the neighboring cell. The mobility management triggered by the second measurement event can be to trigger a measurement of the neighboring cell, thereby handing over to the neighboring cell. The mobility management triggered by any one of the third through tenth measurement events can be to hand over to the neighboring cell. The mobility management triggered by event A6 can be to hand over to the neighboring cell.

[0166] Optionally, after a corresponding measurement event is triggered, the terminal can send a measurement report based on the reporting duration.

[0167] For example, in section 2.1, the terminal can send a measurement report based on a first reporting duration. For instance, the terminal sends a measurement report when the first reporting duration has elapsed. Upon receiving this measurement report, the network device can then determine that the terminal has requested a handover from the second cell to the first cell.

[0168] Optionally, the start time of the first reporting duration is the time when the third measurement event is triggered. That is, the start time of the first reporting duration is the time when the entry condition for the third measurement event is met. The first reporting duration can be a value greater than 0 ms, such as 80 ms. This allows the network device to notify the terminal to access the first cell more quickly. Because both the first and second cells provide low-power signals, they can be considered energy-saving cells. In other words, after receiving the measurement report, the network device can know that the terminal is requesting a handover from one energy-saving cell to another. This is equivalent to a handover between cells of the same type.

[0169] It should be noted that the reporting duration mentioned in this application can be understood as the period during which the terminal reports measurement reports, such as the reporting trigger duration (timeToTrigger). Optionally, this reporting duration can be notified to the terminal by the network device directly or indirectly, or it can be predefined. For example, this reporting duration can be carried in the configuration information. Taking this reporting duration as the first reporting duration as an example, it is located in the following information element:

[0170]

[0171] For example, in section 2.2, the terminal can send a measurement report based on a second reporting duration. For instance, the terminal can send a measurement report when the second reporting duration has elapsed. Upon receiving this measurement report, the network device can then determine that the terminal has requested a handover from the first cell to the second cell.

[0172] Optionally, the start time of the second reporting duration is the time when the fourth measurement event is triggered. That is, the start time of the second reporting duration is the time when the entry condition for the fourth measurement event is met. The second reporting duration can be a value greater than 0 ms, such as 80 ms. This allows the network device to notify the terminal to access the second cell more quickly. Because both the first and second cells provide low-power signals, they can be considered energy-saving cells. In other words, after receiving the measurement report, the network device can know that the terminal is requesting a handover from one energy-saving cell to another. This is equivalent to a handover between cells of the same type.

[0173] Optionally, the first reporting duration and the second reporting duration can be the same. That is, triggering both the third and fourth measurement events can cause the terminal to switch to the energy-saving cell, so the first and second reporting durations are set to be the same.

[0174] For example, in section 2.3, the terminal can send a measurement report based on a third reporting duration. For instance, the terminal can send a measurement report when the third reporting duration has elapsed. Upon receiving this measurement report, the network device can then determine that the terminal has requested a handover from the second cell to the first cell.

[0175] Optionally, the start time of the third reporting duration is the time when the fifth measurement event is triggered. That is, the start time of the third reporting duration is the time when the entry condition for the fifth measurement event is met. The third reporting duration can be a value greater than 0 ms, such as 80 ms. This allows the network device to notify the terminal to access the first cell more quickly. Because both the first and second cells provide low-power signals, they can be considered energy-saving cells. In other words, after receiving the measurement report, the network device can know that the terminal is requesting a handover from one energy-saving cell to another. This is equivalent to a handover between cells of the same type.

[0176] Optionally, the third reporting duration can be the same as at least one of the first and second reporting durations. That is, triggering the fifth, third, and fourth measurement events can all cause a switch to an energy-saving cell, so the third reporting duration can be set to be the same as at least one of the first and second reporting durations.

[0177] For example, in section 2.4, the terminal can send a measurement report based on the fourth reporting duration. For instance, the terminal can send a measurement report upon reaching the fourth reporting duration. Upon receiving this measurement report, the network device can then determine that the terminal has requested a handover from the first cell to the second cell.

[0178] Optionally, the start time of the fourth reporting duration is the time when the sixth measurement event is triggered. That is, the start time of the fourth reporting duration is the time when the entry condition for the sixth measurement event is met. The fourth reporting duration can be a value greater than 0 ms, such as 80 ms. This allows the network device to notify the terminal to access the second cell more quickly. Because both the first and second cells provide low-power signals, they can be considered energy-saving cells. In other words, after receiving the measurement report, the network device can know that the terminal is requesting a handover from one energy-saving cell to another. This is equivalent to a handover between cells of the same type.

[0179] Optionally, the fourth reporting duration can be the same as at least one of the first, second, and third reporting durations. That is, triggering the sixth, fifth, third, and fourth measurement events can all cause the terminal to switch to the energy-saving cell, so the fourth reporting duration is set to be the same as at least one of the first, second, and third reporting durations.

[0180] For example, in version 2.5, the terminal can send a measurement report based on the fifth reporting duration. For instance, the terminal can send a measurement report upon reaching the fifth reporting duration. Upon receiving this measurement report, the network device can then determine that the terminal has requested a handover from the third cell to the first cell.

[0181] Optionally, the start time of the fifth reporting duration is the time when the seventh measurement event is triggered. That is, the start time of the fifth reporting duration is the time when the entry condition for the seventh measurement event is met. The fifth reporting duration can be a value greater than 0 ms, such as 80 ms. This allows the network device to notify the terminal to access the first cell more quickly. Because the first cell provides low-power signals, and the third cell provides non-low-power signals, the first cell can be considered an energy-saving cell, and the third cell a normal cell. In other words, after receiving the measurement report, the network device can know that the terminal is requesting a handover from one normal cell to another energy-saving cell. This is equivalent to a handover between different cell types.

[0182] Optionally, the fifth reporting duration can be the same as at least one of the first, second, third, and fourth reporting durations. That is, triggering the seventh, sixth, fifth, third, and fourth measurement events can all cause the terminal to switch to an energy-saving cell, so setting the fifth reporting duration to be the same as at least one of the first, second, third, and fourth reporting durations is necessary.

[0183] For example, in version 2.6, the terminal can send a measurement report based on the sixth reporting duration. For instance, the terminal can send a measurement report upon reaching the sixth reporting duration. Upon receiving this measurement report, the network device can then determine that the terminal has requested a handover from the first cell to the third cell.

[0184] Optionally, the start time of the sixth reporting duration is the time when the eighth measurement event is triggered. That is, the start time of the sixth reporting duration is the time when the entry condition for the eighth measurement event is met. The sixth reporting duration can be a value greater than 0 ms, such as 160 ms. This allows the network device to notify the terminal to access the first cell more slowly. Because the first cell provides low-power signals, and the third cell provides non-low-power signals, the first cell can be considered an energy-saving cell, and the third cell a normal cell. In other words, after receiving the measurement report, the network device can know that the terminal is requesting a handover from one energy-saving cell to another normal cell. This is equivalent to a handover between different types of cells.

[0185] Optionally, any one of the reporting durations from the first to the fifth can be shorter than the sixth reporting duration. That is, since triggering the eighth measurement event can cause the terminal to switch to a normal cell, triggering the seventh, sixth, fifth, third, and fourth measurement events can all cause the terminal to switch to an energy-saving cell. To ensure that the network device notifies the terminal to switch to an energy-saving cell earlier than it notifies the terminal to switch to a normal cell, any one of the first to the fifth reporting durations is set to be shorter than the sixth reporting duration.

[0186] For example, in section 2.7, the terminal can send a measurement report based on the seventh reporting duration. For instance, the terminal can send a measurement report upon reaching the seventh reporting duration. Upon receiving this measurement report, the network device can then determine that the terminal has requested a handover from the third cell to the first cell.

[0187] Optionally, the start time of the seventh reporting duration is the time when the ninth measurement event is triggered. That is, the start time of the seventh reporting duration is the time when the entry condition for the ninth measurement event is met. The seventh reporting duration can be a value greater than 0 ms, such as 80 ms. This allows the network device to notify the terminal to access the first cell more quickly. Because the first cell provides low-power signals, and the third cell provides non-low-power signals, the first cell can be considered an energy-saving cell, and the third cell a normal cell. In other words, after receiving the measurement report, the network device can know that the terminal is requesting a handover from one normal cell to another energy-saving cell. This is equivalent to a handover between different cell types.

[0188] Optionally, the seventh reporting duration can be the same as at least one of the first, second, third, fourth, and fifth reporting durations. That is, triggering the ninth, seventh, sixth, fifth, third, and fourth measurement events can all cause the terminal to switch to an energy-saving cell, so setting the seventh reporting duration can be the same as at least one of the first, second, third, fourth, and fifth reporting durations.

[0189] For example, in version 2.8, the terminal can send a measurement report based on the eighth reporting duration. For instance, the terminal can send a measurement report when the eighth reporting duration has elapsed. Upon receiving this measurement report, the network device can then determine that the terminal has requested a handover from the first cell to the third cell.

[0190] Optionally, the start time of the eighth reporting duration is the time when the tenth measurement event is triggered. That is, the start time of the eighth reporting duration is the time when the entry condition for the tenth measurement event is met. The eighth reporting duration can be a value greater than 0 ms, such as 160 ms. This allows the network device to notify the terminal to access the first cell more quickly. Because the first cell provides low-power signals, and the third cell provides non-low-power signals, the first cell can be considered an energy-saving cell, and the third cell a normal cell. In other words, after receiving the measurement report, the network device can know that the terminal is requesting a handover from one energy-saving cell to another normal cell. This is equivalent to a handover between different types of cells.

[0191] Optionally, any one of the reporting durations from the first to the fifth can be less than the eighth reporting duration. That is, since triggering the tenth measurement event can cause the terminal to switch to a normal cell, triggering the seventh, sixth, fifth, third, and fourth measurement events can all cause the terminal to switch to an energy-saving cell. To ensure that the network device notifies the terminal to switch to an energy-saving cell earlier than it notifies the terminal to switch to a normal cell, any one of the first to the fifth reporting durations is set to be less than the eighth reporting duration.

[0192] Optionally, the eighth reporting duration and the sixth reporting duration can be the same. That is, since triggering both the tenth and eighth measurement events can cause the terminal to switch to a normal cell, the eighth reporting duration and the sixth reporting duration are set to be the same.

[0193] It should be understood that the technical solutions of the embodiments of this application can be applied to CA technology or DC technology, specifically:

[0194] In the first scenario, where the primary and secondary cells are co-located in CA technology, or where the primary and secondary network devices are co-located in DC technology, the primary and secondary network devices can be used interchangeably. This means that all network-side actions in this solution are performed by a single site, i.e., by a single network device.

[0195] In the second scenario, where the primary and secondary cells in CA technology are not co-located, or where the primary and secondary network devices in DC technology are not co-located, the network-side actions in this solution are still performed by a single site, such as by the primary network device.

[0196] It is understood that, in order to achieve the aforementioned functions, the device includes corresponding hardware structures and / or software modules for performing each function. Those skilled in the art should readily recognize that, based on the units and algorithm steps of the examples described in conjunction with the embodiments disclosed herein, this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0197] This application embodiment can divide the terminal or network device into functional modules according to the above method examples. For example, each function can be divided into its own functional modules, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module. It should be noted that the module division in this application embodiment is illustrative and only represents one logical functional division. In actual implementation, there may be other division methods.

[0198] See Figure 5 , Figure 5 This is a schematic diagram of a communication device provided in an embodiment of this application. The communication device 500 can be applied to the above-described... Figure 4 In the method shown in the embodiments, such as Figure 5 As shown, the communication device 500 includes a processing module 501 and a transceiver module 502. The processing module 501 may be one or more processors, and the transceiver module 502 may be a transceiver or a communication interface. This communication device can be used to implement the terminal or network device involved in any of the above method embodiments, or to implement the functions of the network element involved in any of the above method embodiments. The network element or network function may be a network component in a hardware device, a software function running on dedicated hardware, or a virtualization function instantiated on a platform (e.g., a cloud platform). Optionally, the communication device 500 may further include a storage module 503 for storing the program code and data of the communication device 500.

[0199] In one example, when the communication device functions as a terminal or is a chip applied within a terminal, it executes the steps performed by the terminal in the above method embodiments. The transceiver module 502 is used for specific execution. Figure 4 The embodiments described herein involve sending and / or receiving actions performed by the terminal, such as supporting the terminal in performing other processes of the techniques described herein. The processing module 501 can be used to support the communication device 500 in performing the processing actions in the above method embodiments, for example, supporting the terminal in performing other processes of the techniques described herein.

[0200] For example, the transceiver module 502 is used to receive configuration information from the network device. The configuration information includes at least a measurement object and a measurement event associated with the measurement object. The measurement object includes a first cell covered by the network device, and the measurement event is used to trigger mobility management. The processing module 501 is used to measure the first cell based on the low-power signal provided by the first cell to obtain a first measurement result. The first measurement result is used to trigger the measurement event. The transceiver module 502 is also used to send a measurement report to the network device. The measurement report indicates that the measurement event has been triggered.

[0201] In one possible implementation, the measurement object also includes a second cell covered by the network device, and the processing module 501 is further configured to measure the second cell based on the low-power signal provided by the second cell to obtain a second measurement result, and the first measurement result and the second measurement result are used to trigger a measurement event.

[0202] In one possible implementation, the measurement object also includes a third cell covered by the network device. The processing module 501 is further configured to measure the third cell based on the non-low power signal provided by the third cell to obtain a third measurement result. The first measurement result and the third measurement result are used to trigger a measurement event.

[0203] In one possible implementation, when the terminal or network device is a chip, the transceiver module 502 can be a communication interface, pins, or circuits. The communication interface can be used to input data to be processed to the processor and can output the processor's processing results. Specifically, the communication interface can be a general purpose input / output (GPIO) interface, which can connect to multiple peripheral devices (such as LCD displays, cameras, radio frequency (RF) modules, antennas, etc.). The communication interface is connected to the processor via a bus.

[0204] Processing module 501 may be a processor, which can execute computer execution instructions stored in the storage module to cause the chip to perform... Figure 4 The method described in the embodiments is further illustrated by the processor, which may include a controller, an arithmetic logic unit (ALU), and registers. For example, the controller is primarily responsible for instruction decoding and issuing control signals for the operations corresponding to the instructions. The ALU is primarily responsible for performing fixed-point or floating-point arithmetic operations, shift operations, and logical operations, and can also perform address operations and conversions. Registers are primarily responsible for storing register operands and intermediate operation results temporarily stored during instruction execution. In specific implementations, the processor's hardware architecture can be an ASIC architecture, a microprocessor without interlocked piped stages architecture (MIPS), an advanced reduced instruction set machine (RISC) machine (ARM) architecture, or a network processor (NP) architecture, etc. The processor can be single-core or multi-core. The storage module can be an in-chip storage module, such as a register or cache. Alternatively, the storage module can be an external storage module, such as ROM or other types of static storage devices capable of storing static information and instructions, RAM, etc.

[0205] It should be noted that the functions of the processor and interface can be implemented through hardware design, software design, or a combination of both; no restrictions are imposed here.
