Communication method and communication device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 28, 2023, with application number 202311294143.3 and application name “Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more particularly, to a communication method and a communication device. Background Art

[0003] In a mobile communication system, network equipment sends measurement configuration information to the terminals it serves. Based on this information, the terminals can measure the signal quality of cells adjacent to their serving cell (also known as neighboring cells). The terminals can report the measurement results to the network equipment, which then determines whether to handover the terminal to a neighboring cell with higher signal quality based on the reported measurement results. This ensures communication continuity while the terminals are on the move.

[0004] However, the current neighboring cell signal quality measurement mechanism suffers from the problems of invalid measurement and high terminal power consumption overhead.

[0005] Summary of the Invention

[0006] 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.

[0007] In a first aspect, a communication method is provided. The method can be executed by a terminal or a module (such as a chip) configured in (or used for) a terminal.

[0008] The method includes: receiving first information, the first information being used to configure a terminal to measure the signal quality of a first cell, the first cell being a neighboring cell of a serving cell of the terminal, the first information including first indication information, the first indication information being used to indicate a valid time period for the terminal to measure the signal quality of the first cell; measuring the signal quality of the first cell within the valid time period to obtain a first measurement result; and sending the first measurement result if the first measurement result meets a measurement reporting condition.

[0009] According to the above solution, 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. This can reduce the power consumption of the terminal and improve the efficiency of the neighboring cell signal quality measurement.

[0010] 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. 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.

[0011] According to the above solution, the network device provides the terminal with candidate measurement time periods corresponding to different speeds, allowing the terminal to determine the effective time period for measuring the first cell based on its own speed. This allows the terminal to more accurately obtain the effective time period that matches its own speed, reduces terminal power consumption, and improves the efficiency of neighboring cell measurements.

[0012] 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 the time unit after N time units starting with the time unit carrying the first information, and N is a positive integer.

[0019] According to the above scheme, the terminal can report cells that do not meet the measurement reporting conditions, so that the network device can believe that the measurement effective time period corresponding to the second cell inferred by the intelligent model is less accurate based on the second information. The network device can 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.

[0022] In a second aspect, a communication method is provided, which can be executed by a network device or a module (such as a chip) configured in (or used for) a network device.

The words "first" and "second" do not limit the quantity or order of execution, and the words "first" and "second" do not necessarily mean different. In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. The use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete way to facilitate understanding. In the embodiments of the present application, at least one (kind) can also be described as one (kind) or multiple (kinds), and multiple (kinds) can be two (kinds), three (kinds), four (kinds) or more (kinds), and this application does not limit it.

[0051] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as long-term evolution (LTE) systems, fifth-generation (5G) communication systems, and wireless fidelity (WiFi) systems. The communication method provided in this application can also be applied to sixth-generation (6G) communication systems and other communication systems evolved after 5G, future communication systems, or other communication systems. This application is not limited to this.

[0052] Figure 1 is a schematic diagram illustrating a possible, non-limiting system. As shown in Figure 1 , communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one RAN node (e.g., 110a and 110b in Figure 1 , collectively referred to as 110) and at least one terminal (e.g., 120a-120j in Figure 1 , collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in Figure 1 ). Terminal 120 is wirelessly connected to RAN node 110. Access network node (or RAN node) 110 is wirelessly or wiredly connected to core network 200. The core network equipment in core network 200 and access network node 110 in RAN 100 can be separate physical devices, or they can be a single physical device that integrates core network logical functions and radio access network logical functions.

[0053] The RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a 4G or 5G mobile communication system, or a future-oriented evolutionary system (such as a 6G mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0054] Access network node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and facilitates wireless access for terminals. Multiple access network nodes 110 in the communication system 10 can be of the same type or different types. In some scenarios, the roles of access network node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminal 120j accessing RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. Access network node 110 and terminal 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.

[0055] 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 (such as 110a in FIG1 ), a micro base station or an indoor station (such as 110b in FIG1 ), 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 onboard 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 this 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 this application may also be a logical node, a logical module or software that can implement all or part of the access network node functions.

[0056] 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 they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0057] 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, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0058] The network device provided in the embodiments of the present application may be an access network node, or the network device may include one or more access network nodes.

[0059] The terminal provided in the embodiments of the present application may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios for communication. The scenario includes, 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 120a, 120j and 120e in Figure 1), a tablet computer, a computer with wireless transceiver function (such as 120g in Figure 1), customer-premises equipment (CPE), a smart point of sale (POS) machine, a wearable device, a vehicle (such as 120b in Figure 1), a drone, a helicopter, an airplane (such as 120i in Figure 1), a ship, a robot, a robotic arm, a sensor, a perception device, or a smart home device (such as 120h in Figure 1), etc.

[0060] This application does not limit the specific technology and specific device form adopted 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 end 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 end 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 end and the destination end of the information / data transmission, such as format changes, etc., but the destination end can understand the valid information / data from the source end. Similar expressions in this application can be understood similarly and will not be repeated here.

[0061] In this application, "sending information / data" refers only to the direction of information / data transmission, including direct transmission over the air interface and indirect transmission by the processing unit through the air interface. "Sending" can also be understood as the "output" of the module interface. "Receiving information / data" refers only to the direction of information / data transmission, including direct reception over the air interface and indirect reception by the processing unit through the air interface. "Receiving" can also be understood as the "input" of the module interface.

[0062] Figure 2 is a schematic diagram of the current measurement-based cell handover process. As shown in Figure 2, the process includes but is not limited to the following steps:

[0063] 1. The source access network node sends measurement configuration information to the terminal.

[0064] The source access network node, as an access network node providing communication services to the terminal, sends measurement configuration information to the terminal. The measurement configuration information is used to configure the terminal to perform signal quality measurement of neighboring cells.

[0065] 2. The terminal performs signal quality measurement of neighboring cells according to the measurement configuration information.

[0066] The source access network node configures a period for measuring the signal quality of neighboring cells for the terminal through the measurement configuration information. After receiving the measurement configuration information, the terminal periodically measures the signal quality of neighboring cells according to the measurement configuration information.

[0067] 3. The terminal sends a measurement report to the source access network node.

[0068] After measuring the signal quality of the neighboring cell, the terminal obtains a measurement result, and the measurement report includes the measurement result obtained by the terminal. In one embodiment, the source access network node can configure the terminal to periodically send a measurement report to the source access network node through measurement configuration information. The terminal can periodically report the measurement result to the source access network node through measurement reports according to the period configured by the source access network node. In another embodiment, 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.

[0069] 4. The source access network node determines to hand over the terminal to the target cell managed by the target access network node based on the measurement report.

[0070] 5. The source access network node sends a handover request message to the target access network node.

[0071] The handover request information is used to request handover of the terminal to the target cell of the target access network node.

[0072] 6. The target access network node sends a handover request confirmation message to the source access network node.

[0073] 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. The switching request confirmation message is used to confirm switching the terminal to the target cell.

[0074] 7. The source access network node sends a handover command to the terminal.

[0075] After receiving the handover request confirmation information from the target access network node, the source access network node confirms that the target access network node agrees to handover the terminal to the target cell, and then the source access network node sends a handover instruction to the terminal, instructing the terminal to handover to the target cell.

[0076] 8. The terminal switches from the source cell to the target cell, which serves as the serving cell and provides network communication services to the terminal.

[0077] From the above introduction, it can be seen that after the network equipment configures the terminal to perform neighbor cell measurements, the terminal will periodically measure the signal quality of the neighbor cell. However, when the terminal is in a location where the signal quality of the serving cell is better, the neighbor cell measurements performed will not trigger a handover and are invalid measurements. As shown in Figure 3, the terminal has a certain mobility speed, and the terminal periodically performs neighbor cell measurements according to the measurement configuration information. However, the terminal performs multiple measurements in the process of moving from position A to position B, among which some measurements are invalid measurements. Only the neighbor cell signal quality measurements in the overlapping area between the serving cell and the neighbor cell are valid measurements and may trigger a handover. The invalid measurements performed by the terminal cause unnecessary terminal power consumption. If the measurement results are reported periodically, unnecessary terminal power consumption and radio resource waste will be further increased.

[0078] To address the above issues, in an embodiment of the present application, a network device notifies a terminal of the effective time period of a measurement configuration. After receiving the measurement configuration information, the terminal may temporarily refrain from performing signal quality measurements of neighboring cells, but instead perform signal quality measurements during the effective time period. This reduces terminal power consumption and improves the efficiency of neighboring cell signal quality measurements. Specifically, the network device may determine the effective time period for the terminal to measure neighboring cells based on prior information within the serving cell, thereby notifying the terminal of the effective time period of the measurement configuration.

[0079] 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 schematic, and are illustrated as an example, but the present application does not limit the execution subject of the interactive schematic. 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.

[0080] Figure 4 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 steps S401 to S403.

[0081] S401, a network device sends first information to a terminal, where the first information is used to configure the terminal to measure the signal quality of a first cell, where the first cell is a neighboring cell of a serving cell of the terminal. The first information includes first indication information, where the first indication information is used to indicate a valid time period for the terminal to measure the signal quality of the first cell.

[0082] 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.

[0083] The network device can determine the effective time period for the terminal to measure the first cell based on prior information within 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, reducing unnecessary power consumption caused by the terminal measuring the signal quality of the first cell in other time periods.

[0084] In one embodiment, 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 terminal information may include but is not limited to one or more of the terminal's location information, moving direction information or speed information.

[0085] For example, the network device may obtain one or more of the terminal's location information, movement direction information, or speed information from the terminal. Alternatively, the network device may determine the terminal's location based on the downlink beam direction of communication with the terminal. Alternatively, the network device may determine the terminal's speed and / or movement direction based on a reference signal received from the terminal. This application is not limited to this.

[0086] Specifically, the network device may adopt artificial intelligence (AI) technology and 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. 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 serving cell as training data, and obtain the intelligent model by training the model.

[0087] The first information may specifically configure the terminal to measure the signal quality of at least one neighboring cell of the serving cell, where the at least one neighboring cell includes the first cell. The effective time period indicated by the first indication information in the first information may be a common effective time period for the at least one cell. Alternatively, the first information may include indication information corresponding to each of the at least one neighboring cell, where the indication information corresponding to a neighboring cell indicates the effective time period for the terminal to measure the signal quality of the neighboring cell. These two implementations are described below.

[0088] 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.

[0089] 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 the 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:

[0090] 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 the 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.

[0091] 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 specific signal quality 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, this application does not limit this. The measurement configuration information can be carried in the radio resource control (RRC) reconfiguration information.

[0092] In another embodiment, the first information includes at least one piece of measurement object information, where the at least one piece of 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.

[0093] 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:

[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 perform signal quality measurement. The "..." in the above-mentioned 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 embodiment, 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 based on the terminal's speed and the correspondence. The effective time period is the candidate time period corresponding to the terminal's speed among the multiple candidate time periods.

[0098] For example, multiple speed levels can be predefined, such as three speed intervals corresponding to high speed, medium speed, and low speed. The network device can indicate the effective time period corresponding to each speed level through the first indication information. Exemplarily, the effective time period corresponding to the three speed levels indicated by the first indication information can 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, 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 based on the speed level to which the terminal's own speed belongs. For example, 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]. 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 for the terminal to measure signal quality. The network device can configure the correspondence between multiple speeds and candidate time periods for each cell for the terminal through measurement object information based on the relative position of the terminal and the cell, etc. The terminal can determine the effective time period for measuring each neighboring cell based on the terminal's speed.

[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 N of time units, and the starting time unit of the effective time period is the time unit that is N time units after the time unit that carries the first information as the starting time unit, where N is a positive integer.

[0104] In this embodiment, the terminal can specifically determine the number of start time units and duration units of the effective time period based on the first indication information, thereby specifically determining the effective time period. However, the application is not limited to this. The first indication information can also indicate the start time unit and end time unit of the effective time period, or the time unit carrying the first information is defaulted to be 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 and obtains a first measurement result.

[0106] For example, the first information may also instruct the terminal to measure a measurement parameter type of the first cell, such as RSRP. The terminal measures the signal (SSB or reference signal) of the first cell within 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 configure multiple measurement parameter types, which is not limited in this application.

[0107] S403: If 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 further 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 to handover the terminal to the first cell based on the first measurement result.

[0109] Optionally, the first measurement result further 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, based on the first measurement result, updates model parameters of an intelligent model used to infer the effective time period of the first cell. Specifically, the network device may determine that the first measurement result is a relatively accurate measurement result inferred by the intelligent model and update the intelligent model based on the first measurement result. This improves the accuracy of the intelligent model's inference of the effective time period corresponding to the neighboring cells of the serving cell.

[0111] In one embodiment, the first information configures the terminal to measure the signal quality of at least one neighboring cell. The network device may determine that if measurement results are received for some of the at least one neighboring cell, the measurement validity time periods corresponding to these neighboring cells, as inferred by the intelligent model, are relatively accurate. Conversely, for neighboring cells in the at least one neighboring cell for which the terminal does not report corresponding measurement results, the network device may determine that the validity time periods for these neighboring cells, as inferred by the intelligent model, are less accurate. The network device may adjust model parameters of the intelligent model to improve the accuracy of the validity time periods for the neighboring cells inferred by the intelligent model.

[0112] In another embodiment, the first information configures the terminal to measure signal quality of at least one neighboring cell, which also includes a second cell. The terminal further sends second information to the network device, the second information being used to indicate that the second cell does not meet measurement reporting conditions. Accordingly, the network device receives the second information from the terminal and updates the model parameters of the intelligent model based on 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. For example, 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 measured the signal quality of the second cell during the effective time period corresponding to the second cell and obtained a second measurement result, but the second measurement result did 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. For example, the terminal sends 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 solution, the network device notifies the terminal of the effective time period of the measurement configuration. After receiving the measurement configuration information, the terminal may temporarily not perform the signal quality measurement of the neighboring cell, 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 neighboring cell signal quality measurement. 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, by using AI technology to determine the effective time period for the terminal to measure the signal quality of the neighboring cell, it can more accurately infer the effective time period for the terminal to measure the signal quality of the neighboring cell. 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 intelligent model by the network device, and improve the accuracy of the intelligent model in inferring the measurement effective time period corresponding to the neighboring cell.

[0118] In an optional embodiment, if a terminal measures a neighboring cell outside the neighboring cell measurement validity period and obtains a signal quality that meets the measurement reporting conditions, the terminal may report the time information when the signal of the neighboring cell was measured to the network device. Optionally, the terminal may also report the signal quality measurement result of the neighboring cell to the network device. The network device may update the model parameters of the intelligent model based on the time information reported by the terminal. This embodiment can facilitate network device maintenance of the intelligent model and improve the accuracy of the intelligent model's inference of the neighboring cell measurement validity period.
