Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method, apparatus, device, medium and product for reporting cell reselection measurement information. Background Technology

[0002] In a non-terrestrial network (NTN) environment, the cell reselection mechanism of user equipment (UE) supports two measurement methods: time-based and location-based cell reselection measurements.

[0003] When the System Information Block 19 (SIB19) of the serving cell carries the time information of the NTN cell service termination (t-Service), the UE can perform neighbor cell measurements at any time point before t-Service. However, the timing of the UE's measurement start is determined by the UE itself, which can easily lead to the UE failing to successfully reselect a suitable cell when t-Service arrives. In this case, the UE can initiate a reselection measurement when the distance between the UE and the serving cell reference point reaches a distance threshold configured by the network. However, if the distance threshold configured by the network is unreasonable, it will cause the UE to initiate a reselection measurement too early, resulting in measurement results that do not meet the reselection conditions and prolonging the measurement time. It can be seen that the cell reselection process is greatly affected by the t-Service and distance threshold configured by the network, and unreasonable network configuration can easily lead to low cell reselection efficiency and poor accuracy.

[0075] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0076] To make the embodiments of this application clearer, the relevant technical knowledge involved in the embodiments of this application will be introduced as follows:

[0077] like Figure 1 As shown, Non-Terrestrial Network (NTN) is a general term for any network involving non-ground-based flying objects. NTN includes two categories: first, satellite communication networks, including spaceborne platforms such as Low Earth Orbit (LEO), Middle Earth Orbit (MEO), Geostationary Orbit (GEO), and Geosynchronous Orbit (GSO) satellites; and second, High Altitude Platform Systems (HAPs), including aircraft, airships, hot air balloons, helicopters, and drones. Specifically, the NTN application scenarios involved in the embodiments of this application mainly refer to the application scenarios of satellite communication networks.

[0078] In the field of wireless communication technology, cell reselection refers to the process by which a user equipment (UE) selects and switches to a new cell based on signal quality information and configuration conditions provided by the network, in order to ensure continuous communication quality and service. Currently, the UE's cell reselection process typically includes measuring the signal quality of the serving cell and neighboring cells, determining whether the reselection conditions are met, and selecting a target cell to trigger the reselection process.

[0079] For time-based neighbor cell measurements, when the network configures the time information for NTN cell service termination (t-Service), the UE needs to perform neighbor cell measurements at any time point before t-Service and reselect to another cell. However, the time when the UE starts neighbor cell measurements is determined by the UE itself. If the UE starts measurements before t-Service but fails to reselect to another cell, the network side is unsure whether the failure is due to the UE not being able to adapt to a suitable cell after measurement, for example, a cell with good signal quality (CellBarredNTN) being set to "barred" or not existing. The network side is also unsure whether the failure is due to the UE triggering cell reselection measurements too late, for example, the UE starting measurements close to t-Service.

[0080] For location-based neighbor cell measurements, if the network side is configured with distanceThresh, the UE needs to initiate cell reselection measurement when the distance to the serving cell reference point reaches distanceThresh. However, since the distance threshold is configured by the network, if the distanceThresh configured by the network is unreasonable, it will cause the UE to initiate reselection measurement too early, resulting in the measurement result not meeting the reselection conditions, making the measurement time too long, and increasing the UE power consumption.

[0081] Therefore, to address the issues of low cell reselection efficiency and poor accuracy caused by unreasonable network configuration, and to enable the UE to promptly report the start time, location information, and related measurement information of neighbor cell measurements to the network side, thereby optimizing network configuration for the cell reselection process, reducing the time required for cell reselection, lowering UE power consumption, and improving cell reselection efficiency and accuracy, the following detailed description, in conjunction with the accompanying drawings, of a cell reselection measurement information reporting method, apparatus, device, medium, and product provided in this application, through specific embodiments and application scenarios, is presented in detail.

[0082] Please see Figure 2 , Figure 2 This is one of the flowcharts for a cell reselection measurement information reporting method provided in this application embodiment. Executed by a terminal, the method includes the following steps:

[0083] Step 101: Report the first information to the network-side device. The first information is measurement-related information used for NTN cell reselection.

[0084] It is worth noting that the terminal involved in the embodiments of this application can be a wireless terminal device that provides data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the terminal may differ in different systems. For example, in a 5G or 6G system, the terminal device can be called User Equipment (UE). The wireless terminal device can be a USB storage device, other personal computer memory devices, or a dongle. It can also communicate with one or more core networks (CNs) via a Radio Access Network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablets, and Machine-type Communication (MTC) terminal devices. Wireless terminal devices can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote terminals, access terminals, user terminals, user agents, user devices, and wireless access devices and routers / modems that meet the limitations of this definition, but are not limited to these in the embodiments of this application.

[0085] This application's embodiments can be applied to cell reselection processes in both NTN and terrestrial network (TN) scenarios. Therefore, the aforementioned network-side equipment can be satellite base stations, ground control stations, core network equipment, access network equipment, etc. A base station can include multiple cells providing services to terminals. Depending on the specific application, a base station can also be called an access point, or a device in the access network that communicates with wireless terminal devices via one or more sectors on the air interface, or other names. The network equipment can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an IP communication network. The network equipment can also coordinate the attribute management of the air interface. For example, the network devices involved in the embodiments of this application can be evolved network devices (eNBs or e-NodeBs) in long term evolution (LTE) systems, 5G base stations (gNBs) in 5G network architectures (next generation systems), or home evolved Node Bs (HeNBs), relay nodes, femtos, picos, network testing equipment, etc., and are not limited in the embodiments of this application. In some network structures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may also be geographically separated.

[0086] It should be noted that when applied to the NTN scenario in this application embodiment, the terminal or UE can record and report the first information to the network-side device. Since the first information involves measurement-related information of the UE performing cell reselection, the network-side device can optimize the NTN cell reselection configuration accordingly. For example, the configuration of t-Service or cellBarredNTN can be adjusted in a timely manner based on the time or UE location information related to the current time-based neighbor cell measurement and cell reselection process in the first information. Alternatively, the configuration of distanceThresh or cellBarredNTN can be adjusted in a timely manner based on the distance, location, and other information related to the current location-based neighbor cell measurement and cell reselection process in the first information.

[0087] The first information comprises measurement-related information used for cell reselection. Specifically, it may include information related to the distance and time of neighbor cell measurements. For example, distance-related information may include the UE's location when triggering the neighbor cell measurement and the reference distance between the UE's location and the serving cell. Time-related information may include the time the UE triggers the neighbor cell measurement and the time taken from triggering the measurement to completing the cell reselection. Furthermore, the first information may also include specific measurement values ​​of multiple neighbor cells, including neighbor cell type, neighbor cell identifier, Reference Signal Received Power (RSRP), and Reference Signal Received Quality (RSRQ). Additionally, the first information may include identification information of the NTN network or NT network, such as the Public Land Mobile Network (PLMN) identifier (ID). The measurement-related information involved in the first information in this application is not limited to the content listed above and can be adjusted according to the actual situation.

[0088] Specifically, after the network-side device receives the first information sent by the terminal, it can comprehensively optimize the NTN network configuration based on the first information, NTN cell deployment status, and TN cell distribution status. Different NTN configurations can be adjusted and different configuration information determined according to the different types of neighbor cell measurements triggered by the UE, including time-based or location-based neighbor cell measurements.

[0089] In one specific embodiment, when the UE triggers location-based neighbor cell measurement, if the first information includes the time from when the UE triggers the neighbor cell measurement to when the actual cell reselection is completed, and if this time is too long, and the reselected neighbor cell has the best signal quality, the network-side device can consider reducing the distance threshold. In this way, the configuration information determined by the network-side device can be a shorter distance threshold. A shorter distance threshold allows the UE to perform cell reselection earlier, thereby improving user experience and reducing power consumption.

[0090] In another specific embodiment, when the UE triggers time-based neighbor cell measurement and cell reselection (i.e., SIB19 includes t-service), the timing of the UE triggering the neighbor cell measurement can be determined based on the time the UE triggers the neighbor cell measurement in the first information, or the difference between the actual time the UE triggers the neighbor cell measurement and the t-service. The configuration information is then determined accordingly. If the difference between the actual time the UE triggers the neighbor cell measurement and the t-service is small, it indicates that the UE has approached the t-service limit when triggering the neighbor cell measurement, meaning the UE's time management is close to the network-set threshold. In this case, there is no need to adjust the t-service, and the determined configuration information can be the t-service from the first information.

[0091] Therefore, in this embodiment, the network-side device can first determine whether the existing configuration of cell reselection (including t-service, distanceThresh, cellBarredNTN, etc.) is appropriate by combining the NTN cell deployment and TN cell distribution, and then adjust the network configuration according to the first information reported by the UE. After the network-side device configures the optimized cell reselection configuration information, the UE performs cell reselection, which can effectively reduce the time required for cell reselection, reduce UE power consumption, improve user battery life, and improve cell reselection efficiency.

[0092] It should be noted that by determining the configuration information and using it for network configuration, network-side devices can optimize network configuration, enabling terminals to perform subsequent cell reselection more accurately and efficiently. If the configuration information includes an adjusted distance threshold, during the next cell reselection, the terminal can trigger neighbor cell measurement when the distance to the serving cell is less than or equal to the distance threshold in this configuration information, thus quickly achieving cell reselection and improving cell reselection efficiency and accuracy. If the configuration information includes an adjusted t-service, during the next cell reselection, the terminal can reselect a suitable cell before reaching the t-service, flexibly implementing cell reselection.

[0093] In this embodiment, the terminal reports measurement-related information concerning the current cell reselection process or a previously occurred cell reselection process to the network, enabling the network-side device to optimize network configuration for the next cell reselection process based on this measurement-related information. Thus, the network-side device adjusts the network configuration based on the first information reported by the terminal. Consequently, the terminal in this embodiment can perform cell reselection using the optimized cell reselection configuration information, reducing the time required for cell reselection and lowering the terminal's power consumption, thereby improving user battery life and enhancing cell reselection efficiency and accuracy.

[0094] Optionally, before reporting the first information to the network-side device, the method further includes:

[0095] Receive the first configuration information sent by the network-side device;

[0096] The first configuration information is information that instructs the terminal to perform the Nth NTN cell reselection. The first configuration information is determined based on the measurement-related information of the (N-1)th NTN cell reselection, where N is an integer greater than 1.

[0097] In some embodiments of this application, the terminal can perform the current or current NTN cell reselection based on the first configuration information sent by the network-side device before the reselection. Subsequently, the measurement-related information during the current or current NTN cell reselection process can be reported to the network-side device as the first information. The first configuration information is the measurement information related to the terminal's previous cell reselection process. Thus, each cell reselection process can optimize the network configuration based on the previous cell reselection process, improving cell reselection efficiency and extending user battery life.

[0098] Optionally, the measurement-related information includes at least one of the following:

[0099] Distance threshold, wherein the distance threshold is a distance parameter configured by the network-side device through the System Information Block (SIB);

[0100] The reference position when the terminal triggers neighbor cell measurement;

[0101] The first distance is the distance between the reference location and the serving cell;

[0102] First time information, which is used to characterize the time when the terminal triggers neighbor cell measurement;

[0103] The second time information is used to characterize the time interval between the terminal triggering neighbor cell measurement and the terminal completing cell reselection;

[0104] The third time information is used to characterize the difference between the first time information and the time information when the first cell stops serving, where the first cell is the serving cell where the terminal is stationed.

[0105] The second cell, which is the serving cell that the terminal actually reselects;

[0106] The type of the second residential area;

[0107] The neighbor cell measurement information includes at least one of the following: cell type, identification information, reference signal reception power, and reference signal reception quality of the third cell; wherein the third cell is a neighbor cell of the first cell.

[0108] In specific embodiments of this application, the measurement-related information may include one or more of the following: distance threshold, t-service, reference location, first distance, first time information, second time information, third time information, second cell, cell type of the second cell, and neighboring cell measurement information.

[0109] The first distance can be the distance between the reference location when the terminal triggers neighbor cell measurement and the reference point (e.g., the center point) of the serving cell. This first distance can be used to assess the distance between the terminal or UE and the current serving cell, helping the network determine the signal strength and coverage of the cell the UE is accessing. If the distance between the UE and the serving cell exceeds the configured distance threshold, a cell reselection may be triggered.

[0110] The first-time information indicates the time or moment when the UE triggers neighbor cell measurement. Based on the first-time information, it can be determined whether there is a delay in the UE's cell reselection process and to judge the network's response speed when processing the cell reselection request. If the first-time information is too long, there may be congestion or unreasonable configuration on the network side (e.g., unreasonable t-service configuration).

[0111] The second time information represents the time interval between the terminal triggering neighbor cell measurement and the terminal completing cell reselection. If the UE uses time-based cell reselection, the UE needs to initiate measurement before t-service. In this case, the network-side equipment can assess whether the UE performed measurement within the specified time window based on the second time information. If the second time information is large, meaning the time interval between the terminal triggering neighbor cell measurement and the terminal completing cell reselection is long, it indicates a possible problem with the t-setting, where the UE failed to trigger neighbor cell measurement in time, leading to reselection delay. Alternatively, there may be an unreasonable cell priority configuration, where the UE might prioritize cells with poor signal quality, resulting in prolonged reselection time.

[0112] The third time information can represent the difference between the first time information and the time when the cell where the terminal is camped stops serving. If the network is configured for time-based cell reselection, that is, the SIB19 carries the t-service and the first information also contains the t-service, then there is no need to consider the first distance. The third time information can be used to determine whether the UE triggers the neighbor cell measurement before the t-service arrives. The UE only needs to initiate the measurement before the t-service and perform the subsequent cell reselection.

[0113] The second cell is the serving cell that the UE actually reselects after cell reselection. The second cell can be the reselected cell with the best signal quality or the highest frequency priority. However, due to situations such as a cell being in a connection-banned state (e.g., the highest priority reselected cell's SIB1 has cellBarredNTN set to "barred," or doesn't carry cellBarredNTN information in SIB1), this reselected cell is set to block connections to NTN, and the UE cannot reselect to that cell. Therefore, the second cell may not be the reselected cell with the best signal quality or the highest frequency priority. Furthermore, the cell type of the second cell can indicate whether it is a TN or NTN cell, and may also include information such as the second cell's frequency priority and signal quality level.

[0114] Neighbor cell measurement information may include measurement information related to the third cell, specifically including the cell type and identification information of the third cell, and may also include measured parameter values ​​related to cell signal quality, such as reference signal received power and reference signal received quality. In this embodiment, the network-side device can evaluate the availability and quality of neighboring cells through the neighbor cell measurement information in the first information, helping the network determine the frequency priority or signal quality level of each neighboring cell during the terminal cell reselection process.

[0115] In addition, the first information may also include identification information of the NTN network, such as PLMN ID, to help network-side equipment identify the specific NTN network to which the UE is connected, thereby enabling corresponding management and optimization.

[0116] Optionally, reporting the first information to the network-side device includes:

[0117] The system receives second information sent by the network-side device, the second information including at least first indication information, the first indication information being used to indicate whether to send the first information;

[0118] When the first indication information indicates that the first information can be sent to the access network, the first information is reported to the network-side device corresponding to the network identification information based on the network identification information stored in the second information.

[0119] In some optional embodiments, before the UE reports the first information to the network-side device in the access connection state, it can determine whether the UE can send the first information to the network-side device based on second information related to network configuration. The second information may include first indication information, which can be used to indicate whether the UE can send the first information to the network-side device (including NTN and NT). By using the first indication information, the UE can determine whether the transmission conditions are met before reporting the first information; if not, the UE will not report, thereby reducing the burden on the network-side device, lowering the risk of network congestion, saving network resources, and reducing UE power consumption.

[0120] Specifically, when the first indication information indicates that the UE can report the first information, the network identification information stored in the second information can instruct the UE to send the first information to which NTNs or NTs. The network identification information stored in the second information can specifically be a PLMN ID list, etc., which records all network identifiers that can send the first information.

[0121] In one specific embodiment, if the first indication information indicates that the first information can be reported to other TNs or NTNs, and the network identification information stored in the second information provides network information that can send measurement information (such as PLMN ID1, PLMN ID2, etc.), then after entering the connected state, the UE performs a PLMN ID query to confirm whether the network it accesses is PLMN ID1. If the identifier of the network accessed by the UE is PLMN ID1, then the UE sends the recorded report or the first information to the currently accessed network. Furthermore, the UE can determine whether its network identifier matches a predetermined network identifier based on the PLMN ID in the first information; if it does, it needs to forward the first information to the source network (i.e., the NTN used to record measurement-related information).

[0122] In this way, the UE in this application embodiment can flexibly determine whether it can report the first information to NTN or NT based on the second information related to network configuration, thereby saving network resources and reducing UE power consumption.

[0123] Optionally, the first information is stored in a first reporting module or a second reporting module of the terminal, wherein the first reporting module is used to store reports related to terrestrial networks and non-terrestrial networks, and the second reporting module is used to store reports related to non-terrestrial networks;

[0124] The method further includes any one of the following:

[0125] When the first information is stored in the first report in the first report module, the first information is marked with the identification information of the non-terrestrial network related to the first information and / or the cell identifier;

[0126] When the first information is stored in the first report module, an information element for recording the first information is added to the first report module;

[0127] If the first information is stored in the second report module, a second report is set in the second report module, and the second report is used to store the first information.

[0128] In some alternative embodiments, during the process of the first information being reported by the UE to the network-side device, the first information can also be stored in the UE's existing first reporting module or a newly added second reporting module. The first reporting module can be a Self-Organized Network (SON) / Minimization of Drive-Test (MDT) report in the UE. This SON / MDT report is originally used by the UE to store measurement information related to the NT cell. In this embodiment, the first information can be recorded in the SON / MDT report to accurately record and analyze cell reselection measurement information and performance data, optimize network services, and improve user connection quality and experience.

[0129] Furthermore, for the first information stored in the first report module, it is necessary to distinguish it from NT-related measurement information. This can be achieved by marking the first information with identification information of non-terrestrial networks related to the first information (e.g., carrying the PLMN ID) and / or Physical Cell Identifier (PCI), thus differentiating the first information from other recorded NT measurement information. Additionally, for cases where the PLMN ID of the NTN and the PLMN ID of the TN are the same, in addition to marking with PCI, further identification can be achieved by recording the frequency information of each network. In this way, by distinguishing between different network types (NTN and TN), network operators can better perform data analysis, identify performance bottlenecks and optimization needs of various networks, and thus formulate more effective network management strategies.

[0130] In addition, an InformationElement (IE) can be added to the first report module to record the first information. The information element can be used specifically to record the measurement information of NTN, that is, the first information. In this way, the measurement information related to NTN can be distinguished from the measurement information related to NT.

[0131] In another embodiment, the first information can also be recorded in other reporting modules within the UE. For example, a second reporting module can be added to the UE, and a second report can be set up in the second reporting module to separately record and store the first information. Thus, in different network environments, the UE can flexibly choose the recording method to adapt to diverse network requirements, thereby improving the adaptability and flexibility of the network.

[0132] In another embodiment of this application, a method for reporting cell reselection measurement information is also provided, which is executed by a network-side device and specifically includes the following steps:

[0133] Step 201: Receive the first information reported by the terminal, wherein the first information is measurement-related information for cell reselection;

[0134] Step 202: Determine second configuration information based on the first information; wherein the second configuration information includes parameter information related to the terminal performing the next NTN cell reselection.

[0135] It should be noted that the specific implementation method of the cell reselection measurement information reporting method executed by the network-side device can be found in the relevant descriptions in the embodiments of the cell reselection measurement information reporting method executed by the terminal. To avoid repetition, this embodiment will not repeat the description.

[0136] Optionally, the cell reselection information includes at least one of the following:

[0137] Distance threshold, wherein the distance threshold is the distance parameter configured by the network-side device through system information block SIB19;

[0138] The reference position when the terminal triggers neighbor cell measurement;

[0139] The first distance is the distance between the reference location and the serving cell;

[0140] First time information, the first time information is the time when the terminal triggers the neighbor cell measurement;

[0141] The second time information is the time interval between the terminal triggering neighbor cell measurement and the terminal completing cell reselection;

[0142] The third time information is the difference between the first time information and the time information when the first cell stops serving, where the first cell is the serving cell where the terminal is stationed.

[0143] The second cell, which is the serving cell that the terminal actually reselects;

[0144] The type of the second residential area;

[0145] The neighbor cell measurement information includes at least one of the following: cell type, identification information, reference signal reception power, and reference signal reception quality of the third cell; wherein the third cell is a neighbor cell of the first cell.

[0146] Optionally, when the terminal triggers location-based neighbor cell measurement, the first information includes the first time information, the distance threshold, the second cell, and the neighbor cell measurement information;

[0147] The step of determining the second configuration information based on the first information includes:

[0148] If the frequency priority of the second cell is greater than the frequency priority of any of the third cells, and the time represented by the first time information is later than the first preset time, the distance threshold is adjusted to obtain the second configuration information.

[0149] It should be understood that time-based and location-based measurements are not configured simultaneously during cell reselection. Therefore, the content of the first information may differ depending on the type of measurement. When a terminal triggers distance-based neighbor cell measurements, the first information may include first time information, distance threshold, second cell and neighbor cell measurement information, etc.

[0150] In some optional embodiments, the UE triggers location-based neighbor cell measurements for cell reselection, and the second cell (i.e., the cell the UE actually reselects) is the cell with the highest frequency priority and best signal quality among all the neighbor cells measured by the UE. Simultaneously, if the time represented by the first time information is later than a first preset time, meaning the time from triggering the neighbor cell measurement to the actual reselection completion is too long, it indicates that the distance threshold configuration is unreasonable, and the UE triggers cell reselection too late, requiring adjustment of the distance threshold. In this case, by lowering the distance threshold, configuration information can be obtained, enabling optimization of the NTN configuration, reducing reselection measurement time, and lowering UE power consumption.

[0151] Optionally, determining the second configuration information based on the first information further includes:

[0152] If the frequency priority of the second cell is less than or equal to the frequency priority of the third cell, and the fourth cell is set to disabled or the information of the fourth cell is not carried in the SIB1 of the network-side device, adjust the NTN configuration of the fourth cell;

[0153] The second configuration information is determined based on the adjusted NTN configuration of the fourth cell;

[0154] The fourth cell is the cell with the highest frequency priority among the multiple neighboring cells of the first cell.

[0155] In some optional embodiments, if the second cell is not the cell with the best signal quality of the highest frequency priority among all the neighboring cells measured by the UE, that is, the frequency priority of the second cell is less than or equal to the frequency priority of any of the neighboring cells of the second cell, then it is necessary to confirm whether the high-priority cell measured by the UE has been barred.

[0156] Specifically, it needs to be confirmed whether the SIB1 of the highest frequency priority reselection cell reported by the UE has cellBarredNTN set to barred, or whether cellBarredNTN information is not carried in SIB1. In this case, the network-side equipment can adjust the cellBarredNTN setting of that cell to set the highest priority cell (i.e., the fourth cell) as cellBarredNTN, that is, the determined configuration information includes cellBarredNTN, so as to achieve optimized NTN configuration.

[0157] Optionally, when the terminal triggers a time-based neighbor cell measurement, determining the second configuration information based on the first information includes:

[0158] If the frequency priority of the second cell is lower than that of the third cell, and the fourth cell is set to disabled or the information of the fourth cell is not carried in the SIB1 of the network-side device, adjust the NTN configuration of the fourth cell.

[0159] The second configuration information is determined based on the adjusted NTN configuration of the fourth cell;

[0160] The fourth cell is the cell with the highest frequency priority among the multiple neighboring cells of the first cell.

[0161] In some optional embodiments, when the UE triggers time-based neighbor cell measurements for cell reselection, if the cell actually reselected by the UE (i.e., the second cell) is not the cell with the best signal quality among all the neighbor cells measured by the UE, it is necessary to confirm whether the high-priority cell measured by the UE has been barred. That is, it is necessary to confirm whether the SIB1 of the highest frequency priority reselection cell reported by the UE has cellBarredNTN set to barred, or whether cellBarredNTN information is not carried in SIB1. In this case, the network-side device can optimize the NTN configuration by adjusting the cell's setting to cellBarredNTN, i.e., ensuring that the determined configuration information includes cellBarredNTN.

[0162] Furthermore, if the UE fails to reselect a suitable cell, i.e., the UE does not select a second cell, or the UE has reached t-service before reselecting a suitable cell, and the time when the UE triggers neighbor cell measurement is close to t-service, or the difference between the actual time when the UE triggers neighbor cell measurement and t-service is too small, it indicates that the UE has approached the t-service limit when triggering neighbor cell measurement. In other words, the UE has approached the threshold set by the network in terms of time management. At this time, there is no need to adjust t-service, and the determined configuration information can be the t-service in the first information.

[0163] Thus, the above embodiments of this application enable optimized configuration after cell reselection, determination of configuration parameters, and reasonable execution of the next cell reselection, thereby reducing the time required for cell reselection, reducing UE power consumption, and improving user battery life.

[0164] Please see Figure 4 In some embodiments of this application, a method for reporting cell reselection measurement information is provided, specifically including the following steps:

[0165] Step 301: The network-side device sends first configuration information to the terminal. The first configuration information is information instructing the terminal to perform the Nth NTN cell reselection. The first configuration information is determined based on the measurement-related information of the (N-1)th NTN cell reselection.

[0166] Step 302: Perform the Nth NTN cell reselection;

[0167] Step 303: The network-side device sends second information to the terminal. The second information includes at least first indication information, which is used to indicate whether to send the first information.

[0168] Step 304: Store the first information in the first report module or the second report module. The first information is measurement-related information used for cell reselection.

[0169] Step 305: If the first instruction information indicates that the first information should be sent, the first information should be reported to the network-side device corresponding to the network identification information based on the network identification information stored in the second information.

[0170] Step 306: Determine configuration information based on the first information. The configuration information includes parameter information related to the terminal performing cell reselection.
