Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Art

[0002] In a mobile communication system, a network device sends measurement configuration information to a terminal it serves. The terminal can measure the signal quality of the neighboring cells (also called neighboring cells) of the terminal's service cell based on the measurement configuration information. The terminal can report the measurement results to the network device, so that the network device can determine whether to switch the terminal to a neighboring cell with higher signal quality based on the measurement results of the neighboring cells reported by the terminal. This can maintain the communication continuity of the terminal when it is moving.

[0003] However, the current neighboring cell signal quality measurement mechanism has the problems of invalid measurement and high terminal power consumption overhead. Summary of the invention

[0004] The embodiments of the present application provide a communication method and a communication device, which can reduce terminal power consumption and improve the efficiency of neighboring cell signal quality measurement.

[0005] In a first aspect, a communication method is provided. The method may be executed by a terminal or a module (such as a chip) configured in (or used for) a terminal.

[0006] The method includes: receiving first information, the first information being used to configure a terminal to measure a signal quality of a first cell, the first cell being a neighboring cell of a service cell of the terminal, the first information including first indication information, the first indication information being used to indicate an effective time period for the terminal to measure the signal quality of the first cell; measuring the signal quality of the first cell within the effective time period to obtain a first measurement result; and sending the first measurement result if the first measurement result meets a measurement reporting condition.

[0007] According to the above scheme, the network device can notify the terminal of the effective time period of the measurement configuration. After receiving the measurement configuration information, the terminal can temporarily not perform the signal quality measurement of the neighboring cell, but perform the signal quality measurement during the effective time period, which can reduce the power consumption of the terminal and improve the efficiency of the neighboring cell signal quality measurement.

[0008] In combination with the first aspect, in certain implementations of the first aspect, the first indication information is used to indicate the correspondence between multiple speeds and multiple candidate time periods, and the method also includes: determining the effective time period based on the speed of the terminal and the correspondence, and the effective time period is a candidate time period among the multiple candidate time periods corresponding to the speed of the terminal.

[0009] According to the above solution, the network device can provide the terminal with candidate measurement time periods corresponding to different speeds, so that the terminal can determine the effective time period for measuring the first cell according to the terminal's own speed. This enables more accurate acquisition of the effective time period that matches the terminal's own speed, reduces terminal power consumption, and improves the efficiency of neighboring cell measurement.

[0010] In combination with the first aspect, in certain implementations of the first aspect, the first indication information indicates the starting time unit of the effective time period and the number of time units included in the effective time period; or, the first indication information indicates the number N of time units, and the starting time unit of the effective time period is a time unit after N time units starting from the time unit carrying the first information, and N is a positive integer.

In order to facilitate the description of the technical solution of the embodiment of the present application, in the embodiment of the present application, the words "first" and "second" can be used to distinguish. The words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not necessarily limit the difference. In the embodiment of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or explanations, and any embodiment or design described as "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or design. The use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way for easy understanding. In the embodiments of the present application, at least one (kind) can also be described as one (kind) or more (kinds), and more (kinds) can be two (kinds), three (kinds), four (kinds) or more (kinds), and the present application does not impose any limitation.

[0049] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: long term evolution (LTE) system, fifth generation (5G) communication system, wireless fidelity (WiFi) system, and the communication method provided by the present application can also be applied to the sixth generation (6G) communication system and other communication systems evolved after 5G, future communication systems or other communication systems. The present application does not limit this.

[0050] Figure 1 FIG. 1 is a schematic diagram showing a possible, non-limiting system. Figure 1 As shown, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (e.g. Figure 1 110a and 110b, collectively referred to as 110) and at least one terminal (such as Figure 1 RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1 The terminal 120 is connected to the RAN node 110 in a wireless manner. The access network node (or RAN node) 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the access network node 110 in the RAN 100 can be different physical devices, or the same physical device that integrates the core network logical function and the wireless access network logical function.

[0051] RAN 100 may be a cellular system related to the third generation partnership project (3GPP), for example, a 4G, 5G mobile communication system, or a future evolution system (for example, a 6G mobile communication system). RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a wireless fidelity (wireless fidelity, WiFi) system. RAN 100 may also be a communication system that integrates two or more of the above systems.

[0052] The access network node 110, which may also be sometimes referred to as an access network device, a RAN entity or an access node, etc., constitutes a part of the communication system to help the terminal achieve wireless access. The multiple access network nodes 110 in the communication system 10 may be nodes of the same type or nodes of different types. In some scenarios, the roles of the access network node 110 and the terminal 120 are relative, for example, Figure 1 The network element 120i may be a helicopter or a drone, which may be configured as a mobile base station. For the terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The access network node 110 and the terminal 120 are sometimes referred to as communication devices, for example Figure 1 The network elements 110a and 110b may be understood as communication devices having base station functions, and the network elements 120a-120j may be understood as communication devices having terminal functions.

[0053] In one possible scenario, the access network node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The access network node may be a macro base station (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the example), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the access network node may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the access network node in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The access network node in the present application may also be a logical node, a logical module or software that can implement all or part of the functions of the access network node.

[0054] In another possible scenario, multiple access network nodes collaborate to assist the terminal in achieving wireless access, and different access network nodes respectively implement part of the functions of the base station. For example, the access network node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0055] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0056] The network device provided in the embodiment of the present application may be an access network node, or the network device may include one or more access network nodes.

[0057] The terminal provided in the embodiments of the present application may also be referred to as a terminal device, user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios for communication. The scenario includes, for example, but is not limited to at least one of the following scenarios: enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communications (mMTC), D2D, V2X, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, perception terminal, communication and perception integrated terminal, or smart city, etc. The terminal can be a mobile phone (such as Figure 1 120a, 120j and 120e in the above), tablet computers, computers with wireless transceiver functions (such as Figure 1 120g in), customer-premises equipment (CPE), smart point of sale (POS) machines, wearable devices, vehicles (such as Figure 1 120b), drones, helicopters, airplanes (such as Figure 1 120i in ), ships, robots, robotic arms, sensors, perceptions, or smart home devices (such as Figure 1 120h in) etc.

[0058] This application does not limit the specific technology and specific device form used by the terminal. It should be understood that in this application, "sending information / data to... (such as a terminal)" can be understood as the destination of the information being the terminal. It can include sending information / data directly or indirectly to the terminal. "Receiving information / data from... (such as a terminal)" can be understood as the source of the information being the terminal, which can include receiving information / data directly or indirectly from the terminal. The information / data may be subjected to necessary processing between the source and destination of the information / data transmission, such as format changes, etc., but the destination can understand the valid information / data from the source. Similar expressions in this application can be understood similarly and will not be repeated here.

[0059] In this application, "sending information / data" only refers to the direction of information / data transmission, including direct transmission via the air interface and indirect transmission via the air interface by the processing unit, and "sending" can also be understood as the "output" of the module interface. "Receiving information / data" only refers to the direction of information / data transmission, including direct reception via the air interface and indirect reception via the air interface by the processing unit, and "receiving" can also be understood as the "input" of the module interface.

[0060] Figure 2 This is a schematic diagram of the current measurement-based cell switching process. Figure 2 As shown, the process includes but is not limited to the following steps:

[0061] 1. The source access network node sends measurement configuration information to the terminal.

[0062] The source access network node, as an access network node that provides communication services to the terminal, sends measurement configuration information to the terminal, where the measurement configuration information is used to configure the terminal to perform signal quality measurement of neighboring cells.

[0063] 2. The terminal performs signal quality measurement of neighboring cells according to the measurement configuration information.

[0064] The source access network node configures a period for measuring the signal quality of the neighboring cell for the terminal through the measurement configuration information. After receiving the measurement configuration information, the terminal periodically measures the signal quality of the neighboring cell according to the measurement configuration information.

[0065] 3. The terminal sends a measurement report to the source access network node.

[0066] The terminal measures the signal quality of the neighboring cell and obtains the measurement result, and the measurement report includes the measurement result obtained by the terminal. In one way, the source access network node can configure the terminal to periodically send measurement reports to the source access network node through measurement configuration information. The terminal can periodically report the measurement results to the source access network node through measurement reports according to the period duration configured by the source access network node. In another way, the source access network node can configure event-triggered measurement result reporting for the terminal through measurement configuration information. If the measurement result reporting conditions corresponding to the measurement event are met, the terminal sends a measurement report to the source access network node, and the measurement report includes the measurement results that meet the reporting conditions.

[0067] 4. The source access network node determines to switch the terminal to the target cell managed by the target access network node based on the measurement report.

[0068] 5. The source access network node sends a switching request message to the target access network node.

[0069] The handover request information is used to request handover of the terminal to the target cell of the target access network node.

[0070] 6. The target access network node sends a handover request confirmation message to the source access network node.

[0071] When the target access network node receives a request to switch the terminal to the target cell, the target access network node sends a switching request confirmation message to the source access network node, where the switching request confirmation message is used to confirm switching the terminal to the target cell.

[0072] 7. The source access network node sends a switching command to the terminal.

[0073] After the source access network node receives the handover request confirmation information from the target access network node and confirms that the target access network node agrees to handover the terminal to the target cell, the source access network node sends a handover instruction to the terminal, instructing the terminal to handover to the target cell.

[0074] 8. The terminal switches from the source cell to the target cell, and the target cell serves as the service cell to provide network communication services for the terminal.

[0075] From the above introduction, it can be known that after the network equipment configures the terminal to perform neighboring cell measurement, the terminal will periodically measure the signal quality of the neighboring cell. However, when the terminal is in a location with good signal quality in the serving cell, the neighboring cell measurement performed will not trigger a handover and is an invalid measurement. Figure 3 As shown in the figure, the terminal has a certain moving speed, and the terminal periodically performs neighboring cell measurements according to the measurement configuration information. The terminal performs multiple measurements in the process of moving from position A to position B, among which some measurements are invalid measurements, and only the neighboring cell signal quality measurement in the overlapping area between the serving cell and the neighboring cell is a valid measurement, which may trigger switching. The invalid measurements performed by the terminal cause unnecessary terminal power consumption. If the reporting method of the measurement results is periodic reporting, unnecessary terminal power consumption and waste of wireless resources will be further increased.

[0076] In view of the above problems, in an embodiment of the present application, the network device notifies the terminal of the effective time period of the measurement configuration, and the terminal may temporarily not perform the signal quality measurement of the neighboring cell after receiving the measurement configuration information, but perform the signal quality measurement during the effective time period, which can reduce the power consumption of the terminal and improve the efficiency of the signal quality measurement of the neighboring cell. Specifically, the network device can determine the effective time period for the terminal to measure the neighboring cell based on the prior information in the serving cell, thereby notifying the terminal of the effective time period of the measurement configuration.

[0077] In the communication method provided in the embodiment of the present application, a network device and a terminal are used as the execution subject of the interactive indication as an example for illustration, but the present application does not limit the execution subject of the interactive indication. The function / step implemented by the network device in the method provided in the embodiment of the present application can also be implemented by a module (such as a chip, a chip system, or a processor) applied to the network device, or can be implemented by a logical node, a logical module, or software that can implement all or part of the network device. The function / step implemented by the terminal in the method provided in the embodiment of the present application can also be implemented by a module (such as a chip, a chip system, or a processor) applied to the terminal, or can be implemented by a logical node, a logical module, or software that can implement all or part of the terminal function.

[0078] Figure 4 400 is a schematic flow chart of a communication method 400 provided in an embodiment of the present application. The method 400 includes but is not limited to the following S401 to S403.

[0079] S401, a network device sends first information to a terminal, where the first information is used to configure the terminal to measure a signal quality of a first cell, where the first cell is a neighboring cell of a service cell of the terminal, and the first information includes first indication information, where the first indication information is used to indicate an effective time period for the terminal to measure the signal quality of the first cell.

[0080] Correspondingly, the terminal receives the first information from the network device, determines to measure the signal quality of the first cell according to the first information, and determines the effective time period for measuring the signal quality of the first cell according to the first indication information.

[0081] The network device can determine the effective time period for the terminal to measure the first cell based on prior information in the service cell, and notify the terminal of the effective time period for measuring the signal quality of the first cell through the first information, so that the terminal measures the signal quality of the first cell within the effective time period indicated by the network device, thereby reducing unnecessary power consumption caused by the terminal measuring the signal quality of the first cell in other time periods.

[0082] In one implementation, the network device inputs the information of the terminal into an intelligent model to obtain the effective time period of the terminal measuring the first cell output by the intelligent model, wherein the information of the terminal may include but is not limited to one or more of the terminal's location information, moving direction information or speed information.

[0083] Exemplarily, the network device may obtain one or more of the location information, moving direction information, or speed information of the terminal from the terminal. Alternatively, the network device may determine the location of the terminal by the downlink beam direction of the communication with the terminal. Alternatively, the network device may also determine the speed and / or moving direction of the terminal by receiving a reference signal from the terminal. This application is not limited to this.

[0084] Specifically, the network device may use artificial intelligence (AI) technology to use an intelligent model to infer the effective time period for the terminal to measure the signal quality of the first cell. For example, the intelligent model may use terminal information as input to infer the effective time period for the terminal to measure the signal quality of the first cell. Among them, the intelligent model may be obtained by the network device from the network side (such as from a core network device or an operation, administration and maintenance (OAM) device). Alternatively, the network device may use the terminal information and measurement results of a large number of terminals obtained in the service cell as training data, and obtain the intelligent model by training the model.

[0085] The first information may specifically configure the terminal to measure the signal quality of at least one neighboring cell of the serving cell, the at least one neighboring cell including the first cell, and the effective time period indicated by the first indication information in the first information may be a common effective time period of the at least one cell. Alternatively, the first information may include indication information corresponding to each neighboring cell in the at least one neighboring cell, and the indication information corresponding to one neighboring cell is used to indicate the effective time period for the terminal to measure the signal quality of the neighboring cell. The two implementation modes are respectively introduced below.

[0086] In one implementation, the effective time period is a common effective time period for the terminal to measure the signal quality of at least one neighboring cell.

[0087] For example, the first information is measurement configuration information sent by the network device to the terminal, and the measurement configuration information configures the terminal to measure the signal quality of at least one neighboring cell. The measurement configuration information includes the first indication information, and the effective time period indicated by the first indication information is the common effective time period corresponding to at least one neighboring cell configured by the measurement configuration information. Exemplarily, the measurement configuration information can be recorded as MeasConfig, and the format of the measurement configuration information MeasConfig can be expressed as follows:

[0088]

[0089] Among them, the measurement configuration information MeasConfig includes measurement object list information measObjectToAddModList, and the measObjectToAddModList can configure at least one neighboring cell whose signal quality needs to be measured for the terminal through MeascObjectToAddModList. The measurement configuration information MeasConfig also includes first indication information, namely the above-mentioned effectivePeriod, and the effective time period configured by the effectivePeriod is the public effective time period corresponding to at least one neighboring cell configured by the measurement object information measObjectToAddModList. The terminal can measure the signal quality of the at least one neighboring cell within the public effective time period indicated by the measurement configuration information.

[0090] It should be noted that the "..." in the above MeasConfig format indicates that the measurement configuration information may also include other information, such as the measurement parameter type of the signal quality that needs to be measured, such as reference signal receiving power (RSRP), signal to interference plus noise ratio (SINR), received signal strength indication (RSSI), etc. One or more measurement parameter types, which are not limited in this application. The measurement configuration information can be carried in the radio resource control (RRC) reconfiguration information.

[0091] In another implementation, the first information includes at least one measurement object information, the at least one measurement object information is used to indicate at least one neighboring cell of the serving cell, and the first indication information is specifically included in the measurement object information used to indicate the first cell.

[0092] For example, the first information is the above-mentioned measurement configuration information MeasConfig, and the measurement object list information measObjectToAddModList in the measurement configuration information may specifically include at least one measurement object information, and the measurement object information may be recorded as MeasObject. Exemplarily, the format of one measurement object information MeasObject may be expressed as follows:

[0093]

[0094] If the measurement object information is used to configure the first cell, it includes effective time information effectivePeriod, and the effective time period configured by the effectivePeriod is the effective time period for the terminal to measure the first cell. If the measurement configuration information also configures other cells, the effective time period for the terminal to measure other cells is configured by the measurement configuration information corresponding to the cell.

[0095] The network device can configure the terminal to specifically measure the synchronization signal block (SSB) of the neighboring cell to obtain the signal quality of the neighboring cell. The measurement object information may include the frequency information ssbFrequency of the SSB of the neighboring cell and the subcarrier spacing information ssbSubcarrierSpacing of the SSB. The frequency information ssbFrequency notifies the terminal of the frequency band where the SSB of the neighboring cell is located by indicating the absolute radio frequency channel number (ARFCN) value (denoted as ARFCN-Value). The subcarrier spacing information ssbSubcarrierSpacing indicates the subcarrier spacing used by the SSB through SubcarrierSpacing. This allows the terminal to detect the SSB of the neighboring cell in the frequency band where the SSB of the neighboring cell is located based on the measurement object information to measure the signal quality. The "..." in the above measurement object information MeasObject indicates that the measurement object information may also include other information, which is not limited in this application.

[0096] The first indication information may indicate the effective time period in the following manners, but is not limited to the following manners.

[0097] In one implementation, the first indication information is used to indicate the correspondence between multiple speeds and multiple candidate time periods. The terminal can determine the effective time period according to the speed of the terminal and the correspondence. The effective time period is the candidate time period corresponding to the speed of the terminal among the multiple candidate time periods.

[0098] For example, multiple speed levels may be predefined, such as three speed levels corresponding to high speed, medium speed, and low speed respectively, and the network device may indicate the effective time period corresponding to each speed level through the first indication information. Exemplarily, the effective time periods corresponding to the three speed levels indicated by the first indication information may be expressed as follows:

[0099] The speed level is high speed, and the effective time period is [t11, t12]

[0100] The speed level is medium speed, and the effective time period is [t21, t22]

[0101] The speed level is low speed, and the effective time period is [t31, t32]

[0102] After receiving the first information, the terminal can determine the effective time period for measuring the first cell according to the speed level to which the terminal's own speed belongs. If the speed level to which the terminal's speed belongs is low speed, the terminal can determine the effective time period as [t31, t32], and the terminal measures the signal quality of the first cell within the effective time period [t31, t32]. Specifically, the effective time period can be a common effective time period of at least one neighboring cell configured by the network device to measure the signal quality of the terminal. The network device can configure the correspondence between multiple speeds and candidate time periods of each cell for the terminal through the measurement object information according to the relative position of the terminal and the cell. The terminal can determine the effective time period for measuring each neighboring cell according to the speed of the terminal.

[0103] In another embodiment, the first indication information indicates the starting time unit of the effective time period and the number of time units included in the effective time period. Alternatively, the first indication information indicates the number of time units N, and the starting time unit of the effective time period is the time unit after N time units starting with the time unit carrying the first information, and N is a positive integer.

[0104] In this implementation, the terminal can specifically determine the number of start time units and duration units of the effective time period according to the first indication information, thereby specifically determining the effective time period. However, the application is not limited thereto, and the first indication information can also indicate the start time unit and the end time unit of the effective time period, or the time unit carrying the first information is defaulted as the start time unit of the effective time period, and the first indication information also indicates the end time unit of the effective time period. Exemplarily, the time unit can be a time domain symbol, a time domain symbol group, a time slot, a subframe, or a frame.

[0105] S402: The terminal measures the signal quality of the first cell within the effective time period to obtain a first measurement result.

[0106] For example, the first information may also indicate the type of measurement parameter, such as RSRP, that the terminal measures the first cell. The terminal measures the signal (SSB or reference signal) of the first cell during the effective time period according to the first information to obtain the RSRP of the signal. The first measurement result may include the RSRP. The measurement parameter type may also be SINR, RSSI or other parameter types, or the first information may be configured with multiple measurement parameter types, which is not limited in this application.

[0107] S403: When the first measurement result meets the measurement reporting condition, the terminal sends the first measurement result to the network device.

[0108] The first information sent by the network device to the terminal may also include a measurement reporting condition. After obtaining the first measurement result, the terminal determines whether the first measurement result meets the measurement reporting condition. If the measurement reporting condition is met, the terminal sends the first measurement result to the network device. Accordingly, the network device receives the first measurement information from the terminal, and determines whether it is necessary to switch the terminal to the first cell according to the first measurement result.

[0109] Optionally, the first measurement result also includes one or more of time information, speed information or location information when the terminal measures the signal quality of the first cell.

[0110] The network device receives the first measurement result, and updates the model parameters of the intelligent model used to infer the effective time period of the first cell according to the first measurement result. Specifically, the network device may consider that the first measurement result is a more accurate measurement result inferred by the intelligent model, and update the intelligent model based on the first measurement result. In order to improve the accuracy of the effective time period corresponding to the neighboring cell of the serving cell inferred by the intelligent model.

[0111] In one implementation, the first information configures the terminal to measure the signal quality of at least one neighboring cell, and the network device may consider that if the measurement results of some neighboring cells in the at least one neighboring cell are received, the measurement effective time period corresponding to the part of the neighboring cells inferred by the intelligent model is more accurate. Conversely, for the neighboring cells in the at least one neighboring cell for which the terminal does not report the corresponding measurement results, the network device may consider that the accuracy of the effective time period of the neighboring cell inferred by the intelligent model is low, and the network device may adjust the model parameters of the intelligent model to improve the accuracy of the effective time corresponding to the neighboring cell inferred by the intelligent model.

[0112] In another implementation, the first information configures the terminal to measure the signal quality of at least one neighboring cell further including a second cell, and the terminal further sends second information to the network device, the second information being used to indicate that the second cell does not meet the measurement reporting condition. Accordingly, the network device receives the second information from the terminal, and updates the model parameters of the intelligent model according to the second information.

[0113] After measuring the signal quality of at least one neighboring cell configured by the network device, the terminal may report the neighboring cells that do not meet the measurement reporting conditions to the network device.

[0114] Optionally, the second information may indicate a specific reason why the second cell does not meet the measurement reporting condition, such as the second information may indicate that the terminal did not measure the signal quality of the second cell during the effective time period corresponding to the second cell. Alternatively, the terminal measures the signal quality of the second cell during the effective time period corresponding to the second cell, and obtains a second measurement result, but the second measurement result does not meet the measurement reporting condition. The second information may indicate the second measurement result.

[0115] The network device may believe, based on the second information, that the measurement effective time period corresponding to the second cell inferred by the intelligent model is less accurate. The network device may update the model parameters of the intelligent model based on the second information to improve the accuracy of the effective time period corresponding to the neighboring cell inferred by the intelligent model.

[0116] The first measurement result and the second information may be sent by the terminal to the network device separately, or the first measurement result and the second information may be sent by the terminal to the network device together, such as the terminal sending the measurement result information to the network device, and the measurement result information may be the first measurement result and the second information. This application does not limit this.

[0117] According to the above scheme, the network device notifies the terminal of the effective time period of the measurement configuration. The terminal may temporarily not perform the signal quality measurement of the neighboring cell after receiving the measurement configuration information, but perform the signal quality measurement during the effective time period. Compared with the terminal starting to perform the measurement periodically after receiving the measurement configuration information, it can reduce the power consumption of the terminal and improve the efficiency of the signal quality measurement of the neighboring cell. Specifically, the network device can determine the effective time period for the terminal to measure the neighboring cell based on the prior information in the serving cell. For example, the effective time period for the terminal to measure the signal quality of the neighboring cell can be determined by using AI technology, and the effective time period for the terminal to measure the signal quality of the neighboring cell can be inferred more accurately. In addition, the network device can update the model parameters of the intelligent model based on the signal quality measurement results of the neighboring cell obtained in the serving cell, which can realize the real-time adaptive adjustment of the network device to the intelligent model and improve the accuracy of the intelligent model inferring the measurement effective time period corresponding to the neighboring cell.

[0118] In an optional implementation, if the terminal measures a neighboring cell whose signal quality meets the measurement reporting conditions outside the measurement effective time period of the neighboring cell. The terminal can report the time information of measuring the signal of the neighboring cell to the network device. Optionally, the terminal can also report the measurement result of the signal quality of the neighboring cell to the network device. The network device can update the model parameters of the intelligent model according to the time information reported by the terminal. Through this implementation, it can help the network device maintain the intelligent model and improve the accuracy of the intelligent model inferring the effective time period of the neighboring cell measurement.
