Description

Technical Field

[0001] This invention relates to the field of mobile communications, and in particular to a method, apparatus, and device for measuring and reporting NR cell signals from different systems. Background Technology

[0002] Currently, 5G networks have been deployed on a large scale, but network optimization is not ideal, and there are some abnormal network problems in the interoperability (handover) between 5G and 4G networks in actual networks.

[0003] After a UE camps on the NR (New Radio) network for a period of time, the NR network signal weakens, and the UE is redirected to the LTE (Long Term Evolution) network. The LTE network signal is excellent, allowing the UE to perform inter-system measurements and report them to the NR cell under LTE. When the results meet the network's reporting conditions, the UE reports the NR cell measurement results. However, at this point, the NR cell signal strength is poor, and the signal-to-noise ratio is not ideal. This results in the UE being redirected to the weaker NR cell after the measurement results are reported, failing to adequately meet service requirements and significantly impacting service continuity and user experience. Summary of the Invention

[0004] This application provides a method, apparatus, and device for measuring and reporting signals in NR cells of different systems, and optimizes the measurement and reporting mechanism to improve the probability of successful handover from LTE network to NR network.

[0005] Firstly, this application provides a method for reporting NR cell signal measurements from different systems, including:

[0006] Based on the inter-system measurement configuration, the signals of N NR cells in the inter-system are measured, where N is a positive integer;

[0007] Based on the measurement results of each NR cell, determine the NR cells that meet the requirements for measurement reporting events;

[0008] Based on the parameters related to the signal quality of the NR cell in the measurement results, target NR cells that meet the signal quality requirements are selected from the NR cells that meet the requirements for measurement reporting events.

[0009] Report the measurement results of the target NR cell.

[0010] In one or more embodiments, the measurement results include the reference signal received power (RSRP) and the signal-to-noise ratio (SNR).

[0011] Based on the measurement results of each NR cell, the NR cells that meet the requirements for measurement reporting events are identified, including:

[0012] Determine whether the reference signal received power RSRP_n of NR cell n is greater than a set power threshold. If so, determine that NR cell n meets the measurement reporting event requirements, where n is a positive integer and n∈[1,N].

[0013] Based on the parameters related to the signal quality of the NR cell in the measurement results, target NR cells that meet the signal quality requirements are selected from the NR cells that meet the measurement reporting event requirements, including:

[0014] If the signal-to-noise ratio (SNR_n) of NR cell n is greater than the set SNR high threshold (SNR_Th1), then NR cell n is determined to be the target NR cell; or

[0015] If the number of times the signal-to-noise ratio (SNR) of the NR cell n ∈ [SNR_Th2, SNR_Th1] reaches a set number, the NR cell n is determined to be the target NR cell. The SNR_Th2 is an intermediate threshold obtained by adding a set amount to the set low SNR threshold SNR_Th3, and the SNR_Th2 is less than SNR_Th1.

[0016] In one or more embodiments, the NR cell n is associated with a first counter and a second counter. The first counter is used to count the number of times the signal-to-noise ratio (SNR_n) of the NR cell n is in the range of [SNR_Th2, SNR_Th1], and resets to zero when the count reaches a set number. The second counter is used to count the number of times the signal-to-noise ratio (SNR_n) of the NR cell n is in the range of [SNR_Th3, SNR_Th2), and resets to zero when the count reaches a set number. The initial values ​​of the first counter and the second counter are zero.

[0017] In one or more embodiments, the step of selecting target NR cells that meet the signal quality requirements from the NR cells that meet the requirements for measurement reporting events, based on parameters related to the signal quality of the NR cell in the measurement results, includes:

[0018] When the signal-to-noise ratio (SNR) of the NR cell n is determined to be greater than the set SNR high threshold (SNR_Th1), if at least one of the values ​​of the first counter and the second counter associated with the NR cell n is not equal to zero, the values ​​of the first counter and the second counter are reset to zero, and the NR cell n is determined to be the target NR cell.

[0019] In one or more embodiments, the step of selecting target NR cells that meet the signal quality requirements from the NR cells that meet the measurement reporting event requirements based on parameters related to the signal quality of the NR cell in the measurement results includes:

[0020] When determining that the signal-to-noise ratio SNR_n∈[SNR_Th3, SNR_Th1] of the NR cell n, it is determined whether the signal-to-noise ratio SNR_n of the NR cell n is not less than SNR_Th2;

[0021] If the signal-to-noise ratio (SNR_n) of the NR cell n is not less than SNR_Th2, increment the value of the first counter by one; otherwise, increment the value of the second counter by one.

[0022] When at least one of the values ​​of the first counter and the second counter is not equal to 0 and both are less than a set number of times, it is determined that the NR cell n is not the target NR cell; or

[0023] When the value of the first counter equals the set number of times, the values ​​of the first counter and the second counter are reset to zero, and the NR cell n is determined to be the target NR cell; or

[0024] When the value of the second counter equals the set number of times, the values ​​of the first counter and the second counter are reset to zero, and it is determined that the NR cell n is not the target NR cell.

[0025] In one or more embodiments, the set intermediate SNR threshold SNR_Th2 is the value of SNR_Th3+k*(SNR_Th1-SNR_Th3), where k is a set coefficient less than 1.

[0026] In one or more embodiments, the step of selecting target NR cells that meet the signal quality requirements from the NR cells that meet the measurement reporting event requirements based on parameters related to the signal quality of the NR cell in the measurement results includes:

[0027] When the signal-to-noise ratio (SNR_n) of the NR cell n is determined to be less than SNR_Th3, if at least one of the values ​​of the first counter and the second counter associated with the NR cell n is not equal to 0, the values ​​of the first counter and the second counter are reset to zero, and the NR cell n is determined not to be the target NR cell.

[0028] Secondly, this application provides an apparatus for measuring and reporting NR cell signals from different systems, comprising:

[0029] The signal measurement module is used to measure the signals of N NR cells in a different system according to the different system measurement configuration, where N is a positive integer;

[0030] The measurement reporting first screening module is used to determine the NR cells that meet the requirements for measurement reporting events based on the measurement results of each NR cell;

[0031] The measurement reporting second screening module is used to screen out target NR cells that meet the signal quality requirements from the NR cells that meet the measurement reporting event requirements based on the parameters related to the signal quality of the NR cell in the measurement results.

[0032] The measurement result reporting module is used to report the measurement results of the target NR cell.

[0033] Thirdly, this application provides a device for measuring and reporting NR cell signals from different systems, including at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the method described in the first aspect above.

[0034] Fourthly, this application provides a computer-readable storage medium storing computer instructions that, when executed on a computer, cause the computer to perform the method described in the first aspect above.

[0035] The method, apparatus, and equipment for measuring and reporting NR cell signals from different systems provided in this application have the following beneficial effects:

[0036] During the measurement reporting process, based on the measurement results of each NR cell, NR cells that meet the requirements for measurement reporting events are first selected. Then, among the NR cells that meet the requirements for measurement reporting events, NR cells that meet the signal quality requirements are further selected as target NR cells. This optimizes the measurement reporting mechanism by filtering out NR cells that do not meet the requirements for measurement reporting events and signal quality, thereby increasing the probability of a UE successfully switching from the LTE network to the NR network. This reduces the possibility that switching to a poor NR network will affect the continuity of services and the user experience. Attached Figure Description

[0053] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0054] 4G is currently the main network for mobile services, with mature and stable technology and comprehensive and in-depth coverage. 5G, through technological innovation and additional spectrum, supports various scenarios such as enhanced mobile broadband, high reliability and low latency, and low power consumption with massive connectivity, supporting a wide range of applications and business models. However, although 5G networks have been deployed on a large scale, network optimization is not ideal, and some abnormal network issues exist in the interoperability (handover) between 5G and 4G networks in actual network operations.

[0055] like Figure 1 The diagram illustrates the interoperability between an LTE network and an NR network as provided in this embodiment. After a UE camps on the NR (New Radio) network for a period of time, the NR network signal deteriorates, and the UE is redirected to the LTE (Long Term Evolution) network. Meanwhile, the LTE network signal is excellent, enabling the UE to perform inter-system measurement reporting of the NR cell under the LTE network according to the inter-system measurement configuration issued by the base station.

[0056] When the results meet the reporting conditions configured by the network, the NR cell measurement results are reported. However, at this time, the NR cell signal strength is poor and the signal-to-noise ratio is not ideal. As a result, after the NR cell measurement results are reported, the UE is redirected to the NR cell with poor network performance, which cannot meet the service requirements well and greatly affects the continuity of services and user experience.

[0057] In view of the above problems, this application provides a method, apparatus, and device for reporting inter-system NR cell signal measurements. When a UE operating in an LTE network receives an inter-system NR measurement configuration configured by the network, it performs inter-system measurements on N NR cells according to the measurement configuration. During the measurement reporting process, NR cells that meet the requirements for measurement reporting events are first selected. Then, among the NR cells that meet the requirements for measurement reporting events, NR cells that meet the signal quality requirements are further selected as target NR cells for which measurement results can be reported. This optimizes the measurement reporting mechanism, increases the probability of a successful UE handover from an LTE network to an NR network, and reduces the possibility that a UE handover from an LTE network to a poor NR network will affect service continuity and user experience.

[0058] like Figure 2The diagram shown is a flowchart illustrating a method for reporting NR cell signal measurements from different systems, provided in an embodiment of this application. The method includes the following steps:

[0059] S201, according to the inter-system measurement configuration, measure the signals of N NR cells in the inter-system, where N is a positive integer;

[0060] After a UE camps on the NR network for a period of time, if the NR network signal deteriorates, the UE will be redirected to the LTE network. At this time, if the UE is operating on the LTE network and the network signal is very good, when the UE receives the NR inter-system measurement configuration configured by the network under the LTE network, it will perform inter-system measurements on the signals of N NR cells in the inter-system according to the inter-system measurement configuration.

[0061] S202, based on the measurement results of each NR cell, determine the NR cells that meet the requirements for measurement reporting events; if the signal conditions of N NR cells are measured, record the reference signal received power RSRP_n and the signal-to-noise ratio SNR_n of cell n. RSRP_n and SNR_n represent the signal measurement conditions of the nth NR cell, where n is a positive integer, n∈[1,N], meaning that n can take any value from 1, 2…N. Figure 3 The diagram shown illustrates the measurement results of N NR cells provided in this embodiment of the application. The measurement results include the Reference Received Power (RSRP) and Signal-to-Noise Ratio (SNR) of each of the N NR cells.

[0062] When a UE performs inter-system measurements on signals from N NR cells in a different system, it needs to tune the receiver to the frequency of each of the N NR cells to perform inter-frequency measurements. Inter-frequency measurements refer to measurements where the cell the UE is currently in and the NR cell to be measured are not on the same carrier frequency.

[0063] In this context, when measuring the signal conditions of N NR cells, i represents the number of frequency points from which signal values ​​can be measured. Let F_j be the frequency point corresponding to NR cell n, where j <= N, because different NR cells may correspond to the same frequency point. After obtaining the measurement results of the N NR cells, the first step is to select the NR cells that meet the measurement reporting event requirements based on the measurement results of each NR cell. NR cell n meeting its corresponding measurement reporting event requirements means meeting the measurement reporting event requirements corresponding to frequency point F_j.

[0064] For example, this application uses a reference signal received power RSRP greater than a set power threshold as a requirement for satisfying the measurement reporting event corresponding to frequency point F_j. Therefore, if... Figure 4 The diagram shown is a flowchart illustrating the process of determining an NR cell that meets the requirements for a measurement reporting event, as provided in an embodiment of this application. The process includes:

[0065] S401, Obtain the measurement results of each NR cell, the measurement results including the reference signal received power RSRP;

[0066] S402, Based on the measurement results of each NR cell, determine whether the reference signal received power RSRP_n of NR cell n is greater than the set power threshold. If yes, proceed to S403; otherwise, proceed to S404.

[0067] S403, determine that the NR cell n meets the measurement reporting event requirements;

[0068] S404, It is determined that the NR cell n does not meet the measurement reporting event requirements.

[0069] In this embodiment of the application, after determining that the NR cell n does not meet the requirements for measurement reporting events, the judgment of NR cell n ends and the measurement results of NR cell n are not reported.

[0070] The above requirement for determining whether the reference signal received power RSRP_n of NR cell n is greater than the set power threshold is only an example provided by this application embodiment for determining whether NR cell n meets the corresponding measurement reporting event requirements. It can also be set to meet other measurement reporting event requirements, and this application does not limit it.

[0071] S203, Based on the parameters related to the signal quality of the NR cell in the measurement results, select the target NR cell that meets the signal quality requirements from the NR cells that meet the measurement reporting event requirements;

[0072] S204, Report the measurement results of the target NR cell.

[0073] For example, the signal-to-noise ratio (SNR) is selected as a parameter related to the signal quality of the NR cell in the measurement results. The SNR is defined as "the ratio of signal to noise at the device's maximum undistorted output power," so a higher SNR indicates better signal quality for the NR cell. To determine the quality of the NR cell's signal, three SNR thresholds are preset within the UE.

[0074] like Figure 5 The diagram shown is a schematic of the SNR threshold preset inside the UE provided in the embodiment of this application. The SNR threshold preset inside the UE includes a high threshold SNR_Th1, an intermediate threshold SNR_Th2, and a low threshold SNR_Th3.

[0075] Among them, the intermediate threshold SNR_Th2 is the threshold obtained by adding a set amplitude to the low threshold SNR_Th3, and the relationship among the three satisfies SNR_Th1>SNR_Th2>SNR_Th3.

[0076] In one or more embodiments, the intermediate SNR threshold SNR_Th2 is the value of SNR_Th3+k*(SNR_Th1-SNR_Th3), where k is a set coefficient less than 1, and exemplarily, k may be, but is not limited to, 0.5.

[0077] Among the NR cells that meet the requirements for measurement reporting events, the target NR cells that meet the signal quality requirements can be selected by comparing the signal-to-noise ratio (SNR_n) of NR cell n with the SNR threshold preset in the UE.

[0078] In the NR cells that meet the requirements for measurement reporting events, when comparing the signal-to-noise ratio (SNR) of NR cell n with the SNR threshold preset in the UE, there are three cases.

[0079] Case 1: SNR_n is greater than the high threshold SNR_Th1;

[0080] If SNR_n is greater than the high threshold SNR_Th1, it means that the signal quality of the NR cell n is very good, and the UE can meet the service requirements well after switching to the NR cell n. Therefore, it is determined that the measurement results of the NR cell n can be directly reported.

[0081] like Figure 6 The diagram illustrates the process of selecting target NR cells that meet signal quality requirements under scenario 1 provided in this embodiment of the application, including the following steps:

[0082] S601, In NR cells that meet the requirements for measurement reporting events, if the signal-to-noise ratio SNR_n of NR cell n satisfies SNR_n>SNR_Th1, then execute S602;

[0083] S602, determine that the NR cell n meets the signal quality requirements, and determine the NR cell n as the target NR cell.

[0084] Case 2: SNR_n is less than the low threshold SNR_Th3;

[0085] If SNR_n is less than the low threshold SNR_Th3, it means that the signal quality of the NR cell n is poor. After the UE switches to the NR cell n, it cannot meet the service requirements and will affect the user's user experience. Therefore, it is determined not to report the measurement results of the NR cell n this time.

[0086] like Figure 7 The diagram illustrates the process of selecting target NR cells that meet signal quality requirements under scenario 2 provided in this application embodiment, including the following steps:

[0087] S701, In NR cells that meet the requirements for measurement reporting events, if the signal-to-noise ratio SNR_n of NR cell n satisfies SNR_n<SNR_Th3, then execute S702;

[0088] S702, determine that the NR cell n does not meet the signal quality requirements, and determine that the NR cell n is not the target NR cell.

[0089] Case 3: SNR_n is neither greater than the high threshold SNR_Th1 nor less than the low threshold SNR_Th3;

[0090] If SNR_n is neither greater than the high threshold SNR_Th1 nor less than the low threshold SNR_Th3, that is, SNR_n∈[SNR_Th3, SNR_Th1], it means that the signal quality of NR cell n is generally poor and is in an unstable state. The signal quality cannot be judged by a single measurement. If the UE is switched to NR cell n in an unstable state, it may not be able to meet the service requirements well. Therefore, it is necessary to determine the signal quality of NR cell n through multiple judgments.

[0091] In one or more embodiments, when the UE performs inter-system measurements on the signals of N NR cells in different systems according to the measurement configuration, a first counter and a second counter are associated with each NR cell. The initial values ​​of the first counter and the second counter are zero, and when the count reaches a set number, the first counter and the second counter are reset to zero. Based on the count result of the counter, it is determined whether the NR cell that meets the requirements of the measurement reporting event is the target NR cell that meets the signal quality requirements.

[0092] For example, the values ​​of the first and second counters associated with NR cell n are represented by Count_n_1 and Count_n_2, respectively.

[0093] Therefore, when SNR_n∈[SNR_Th3, SNR_Th1] in the NR cell n, the counting rules for Count_n_1 and Count_n_2 are as follows: Figure 8 As shown, it mainly includes:

[0094] Step S801: For NR cell n, SNR_n∈[SNR_Th3, SNR_Th1], determine whether the signal quality requirements are met by using the values ​​of the first counter and the second counter.

[0095] Step S802: Determine whether the SNR_n of NR cell n is not less than the intermediate threshold SNR_Th2. If yes, proceed to step S803; otherwise, proceed to step S804.

[0096] Step S803: If SNR_n is not less than the intermediate threshold SNR_Th2, it is determined that a good signal quality has been measured. The value of Count_n_1 associated with the NR cell n is incremented by one, that is, the number of times SNR_n∈[SNR_Th2, SNR_Th1] of the NR cell n is recorded.

[0097] Increasing the value of Count_n_1 by one indicates that a relatively good NR cell signal quality was measured.

[0098] Step S804: If SNR_n is less than the intermediate threshold SNR_Th2, it is determined that a poor signal quality has been measured. The value of Count_n_2 associated with the NR cell n is incremented by one, that is, the number of times SNR_n∈[SNR_Th3, SNR_Th2) of the NR cell n is recorded.

[0099] In other words, incrementing the value of Count_n_2 by one indicates that a poor NR cell signal quality was detected.

[0100] According to the above counting rules, each time a trigger count is performed, the values ​​of Count_n_1 of the first counter and Count_n_2 of the second counter are used to determine whether the current state is a stable state with poor signal quality, a stable state with good signal quality, or an unstable state with poor signal quality. This determines whether the NR cell that meets the requirements for the measurement reporting event is the target NR cell that meets the signal quality requirements. The specific steps are as follows: Figure 9 As shown, it mainly includes:

[0101] Step S901: When a count of Count_n_1 or Count_n_2 is triggered, obtain the current values ​​of Count_n_1 and Count_n_2.

[0102] As mentioned above, when SNR_n∈[SNR_Th3, SNR_Th1] in NR cell n, count Count_n_1 or Count_n_2 is performed once in accordance with the above steps S803 or S804.

[0103] Step S902: When at least one of the values ​​of the first counter and the second counter is not equal to 0 and both are less than a set number of times, it is determined that the signal quality is unstable, and step S905 is executed.

[0104] For example, when the number of times is set to 2, the current value of Count_n_1 of the first counter associated with NR cell n in SNR_n∈[SNR_Th2, SNR_Th1] in this measurement is 1, and the current value of Count_n_2 is 0, indicating that the signal quality is good but unstable;

[0105] Alternatively, in this measurement, the current value of Count_n_2 of the second counter associated with NR cell n in SNR_n∈[SNR_Th2, SNR_Th1] is 1, and the current value of Count_n_1 is 0, indicating that the signal quality is poor but unstable.

[0106] Step S903: When the value of the first counter is equal to the set number of times, it is determined that the signal quality is good and in a stable state, and step S906 is executed.

[0107] When the value of the first counter Count_n_1 reaches the set number, it indicates that multiple good NR cell signal quality measurements have been performed, and the signal quality is in a stable state with good quality.

[0108] Step S904: When the value of the second counter equals the set number of times, it is determined that the signal quality is poor and in a stable state, and step S907 is executed;

[0109] If the value of Count_n_2 reaches the set number of times, it means that multiple poor NR cell signal quality measurements have been taken, and the signal quality is in a stable state of poor quality.

[0110] Step S905: Determine that the NR cell n is not the target NR cell. Do not report the measurement results of the unstable NR cell n at present, and return to step S901 to continue the signal quality status determination.

[0111] Step S906: Determine that the NR cell n is the target NR cell. Since the signal quality is stable, there is no need to perform state determination. Set the values ​​of the first counter and the second counter to zero, and end the determination of NR cell n.

[0112] Step S907: Determine that the NR cell n is not the target NR cell. Since the signal quality is stable, there is no need to perform state determination. Set the values ​​of the first counter and the second counter to zero, and end the determination of NR cell n.

[0113] When each NR cell is associated with a first counter and a second counter, for case 1, when the NR cell n is determined to be the target NR cell, the values ​​of the first counter and the second counter need to be reset to zero. The specific steps are as follows: Figure 10 As shown, it includes:

[0114] Step S1001: In NR cells that meet the requirements for measurement reporting events, if the signal-to-noise ratio SNR_n of NR cell n satisfies SNR_n>SNR_Th1, then NR cell n meets the signal quality requirements, and proceed to step S1002.

[0115] Step S1002: Determine whether there are any non-zero values ​​among the values ​​of Count_n_1 and Count_n_2 associated with the NR cell n. If so, proceed to S1003; otherwise, proceed to S1004.

[0116] Step S1003: Set the values ​​of Count_n_1 and Count_n_2 to zero, and then execute S1004;

[0117] Step S1004: Determine that the NR cell n is the target NR cell.

[0118] When each NR cell is associated with a first counter and a second counter, in case 2, if it is determined that the NR cell n is not the target NR cell, the values ​​of the first counter and the second counter need to be reset to zero. The specific steps are as follows: Figure 11 As shown, it includes:

[0119] Step S1101: In NR cells that meet the requirements for measurement reporting events, if the signal-to-noise ratio SNR_n of NR cell n satisfies SNR_n < SNR_Th3, then NR cell n does not meet the signal quality requirements, and proceed to S1102.

[0120] Step S1102: Determine whether there are any non-zero values ​​among the values ​​of Count_n_1 and Count_n_2 associated with the NR cell n. If so, proceed to S1103; otherwise, proceed to S1104.

[0121] Step S1103: Set the values ​​of Count_n_1 and Count_n_2 to zero, and then execute S1104;

[0122] Step S1104: Determine that the NR cell n is not the target NR cell.

[0123] For example, taking a set number of times of measurement reporting as an example, the overall process of selecting target NR cells that meet the signal quality requirements from among the NR cells that meet the measurement reporting event requirements, based on Count_n_1 and Count_n_2 associated with NR cell n, is given, as follows: Figure 12 As shown, it includes:

[0124] Step S1200: In the NR cells that meet the requirements for measurement reporting events, obtain the SNR_n of NR cell n;

[0125] Step S1210: Determine that SNR_n > SNR_Th1, indicating that the signal quality is good, and proceed to step S1211;

[0126] Step S1220: Determine that SNR_n < SNR_Th3, indicating poor signal quality, and proceed to step S1221;

[0127] Step S1230: If SNR_n∈[SNR_Th3, SNR_Th1] is determined, it indicates that a signaling quality stability determination is required, and step S1231 is executed.

[0128] Step S1211: Determine whether there are any non-zero values ​​among the values ​​of Count_n_1 and Count_n_2 associated with the NR cell n. If so, proceed to S1212; otherwise, proceed to S1213.

[0129] Step S1212: Set the values ​​of Count_n_1 and Count_n_2 to zero, and then execute S1213;

[0130] Step S1213: Determine that the NR cell n is the target NR cell;

[0131] Step S1221: Determine whether there are any non-zero values ​​among the values ​​of Count_n_1 and Count_n_2 associated with the NR cell n. If so, proceed to S1222; otherwise, proceed to S1223.

[0132] Step S1222: Set the values ​​of Count_n_1 and Count_n_2 to zero, and then execute S1223;

[0133] Step S1223: Determine that the NR cell n is not the target NR cell;

[0134] Step S1231: Determine whether the SNR_n of NR cell n is not less than the intermediate threshold SNR_Th2. If yes, proceed to step S1232; otherwise, proceed to step S1233.

[0135] Step S1232: If SNR_n is not less than the intermediate threshold SNR_Th2, it is determined that a good signal quality has been measured. The value of Count_n_1 associated with the NR cell n is incremented by one, that is, the number of times SNR_n∈[SNR_Th2, SNR_Th1] of the NR cell n is recorded, and step S1234 is executed.

[0136] Step S1233: If SNR_n is less than the intermediate threshold SNR_Th2, it is determined that a poor signal quality has been measured. The value of Count_n_2 associated with the NR cell n is incremented by one, that is, the number of times SNR_n∈[SNR_Th3, SNR_Th2) of the NR cell n is recorded, and step S1234 is executed.

[0137] Step S1234: Obtain the current values ​​of Count_n_1 and Count_n_2;

[0138] Step S1235: When at least one of the values ​​of Count_n_1 and Count_n_2 is not equal to 0 and both are less than 2, it is determined that the signal quality is unstable, and step S1238 is executed.

[0139] Step S1236: When the value of Count_n_1 is equal to 2, it is determined that the signal quality is good and in a stable state, and step S1239 is executed.

[0140] Step S1237: When the value of Count_n_2 is equal to 2, it is determined that the signal quality is poor and in a stable state, and step S123-10 is executed.

[0141] Step S1238: Determine that the NR cell n is not the target NR cell. Do not report the measurement results of the unstable NR cell n at present, and return to step S1200 to continue the signal quality status determination.

[0142] Step S1239: Determine that the NR cell n is the target NR cell. Since the signal quality is stable, there is no need to perform state determination. Set the values ​​of Count_n_1 and Count_n_2 to zero and end the determination of NR cell n.

[0143] Step S123-10: Determine that the NR cell n is not the target NR cell. Since the signal quality status is stable, there is no need to perform status determination. Set the values ​​of Count_n_1 and Count_n_2 to zero and end the determination of NR cell n.

[0144] Based on the above introduction of the three scenarios for selecting target NR cells, a specific implementation method is given below.

[0145] For example, the value of the counter associated with the NR cell is set to zero after reaching 2. Five NR cells are configured in the different system. The high threshold SNR_Th1 is set to -7dBm, the low threshold SNR_Th3 is set to -12dBm, and the intermediate threshold SNR_Th2 is determined to be -9.5dBm according to the value of SNR_Th3+k*(SNR_Th1-SNR_Th3), where k is 0.5.

[0146] like Figure 13 The diagram shown is a flowchart of a method for measuring and reporting NR cell signals from different systems based on a set number of times and a set threshold, provided in an embodiment of this application. The method includes the following steps:

[0147] Step S1301: According to the measurement configuration of the different system, the signals of the five NR cells of the different system are measured.

[0148] Step S1302: Based on the Reference Signal Received Power (RSRP) of the five NR cells, determine that NR cell 1, NR cell 2, and NR cell 3 meet the measurement reporting event requirements.

[0149] Step S1303: Obtain the signal-to-noise ratio of NR cell 1 as -6dBm, the signal-to-noise ratio of NR cell 2 as -9dBm, and the signal-to-noise ratio of NR cell 3 as -10dBm;

[0150] Step S1304a: Determine that the signal-to-noise ratio of NR cell 1 is -6dBm, which is greater than the high threshold of -7dBm;

[0151] Step S1305a: Set the values ​​of Count_n_1 and Count_n_2 associated with NR cell 1 to zero;

[0152] Step S1306a: Determine NR cell 1 as the target NR cell;

[0153] Step S1304b: Determine that the signal-to-noise ratio of NR cell 2 is not less than -9.5dBm and increment the value of Count_n_1 associated with NR cell 2 by 1.

[0154] Step S1305b: Obtain the value of Count_n_1 associated with the current NR cell 2 as 2 and the value of Count_n_2 as 0;

[0155] Step S1306b: Set the values ​​of Count_n_1 and Count_n_2 associated with NR cell 2 to zero;

[0156] Step S1307b: Determine NR cell 2 as the target NR cell;

[0157] Step S1304c: Determine that the signal-to-noise ratio of NR cell 3 is -10dCm, which is less than -9.5dCm, and increment the value of Count_n_2 associated with NR cell 3 by 1;

[0158] Step S1305c: Obtain the value of Count_n_1 associated with the current NR cell 3 as 0 and the value of Count_n_2 as 1;

[0159] Step S1306c: Save the values ​​of Count_n_1 and Count_n_2 associated with NR cell 3;

[0160] Step S1307c: Determine that NR cell 3 is not the target NR cell.

[0161] The measurement reporting method provided in this application, during the measurement reporting process, first filters out NR cells that meet the requirements for measurement reporting events based on the measurement results of each NR cell, and then further filters out NR cells that meet the signal quality requirements as target NR cells from among the NR cells that meet the requirements for measurement reporting events. This optimizes the measurement reporting mechanism by filtering out NR cells that do not meet the requirements for measurement reporting events and signal quality, thereby increasing the probability of successful LTE to NR handover. This avoids the problem of LTE switching to a poor NR network under weak NR conditions affecting service continuity and user experience.
