Description

Method and device for measuring LTE frequency points in different systems, equipment, chip and storage medium

Technical Field

The present invention belongs to the field of communication technology, and in particular relates to a method for measuring a frequency point of LTE in a different system, a measuring device, a user equipment, a network device, a chip and a computer-readable storage medium.

Background Art

According to the communication protocol, under normal circumstances, user equipment (UE) that supports new radio (NR, also known as new wireless) standard communication needs to perform same-frequency, different-frequency, and different-system LTE frequency point measurements and L1-RSRP measurements in the radio resource control (RRC) connection state (RRC_Connected).

Among them, the inter-system LTE frequency measurement is usually used for the decision of inter-system switching and redirection from NR to LTE. For example, when the NR service cell signal changes from strong to weak, the base station configures the measurement object and B1/B2 measurement event of the inter-system LTE frequency for the user equipment. Based on the B1/B2 event of the LTE frequency reported by the user equipment, the base station decides whether to trigger the inter-system switching or redirection from NR to LTE.

However, a user device configured with heterogeneous LTE frequency measurement and having only one set of RF transceivers cannot work on both the service frequency and heterogeneous or heterogeneous LTE frequency at the same time. Therefore, both the LTE system and the NR system define measurement gaps for measurement. LTE frequency measurement includes cell synchronization and cell measurement. Usually, within one measurement gap, the user device can only complete cell synchronization of one LTE frequency or cell measurement of one LTE frequency. Cell measurement depends on cell synchronization. Therefore, for LTE frequencies that are not synchronized to the cell, the user device needs at least two measurement gaps for cell synchronization and cell measurement.

In actual network environments, multi-frequency layered networking is usually adopted, and the coverage direction and range of each carrier frequency are different. When it is necessary to trigger the switch or redirection from NR to LTE, the network usually configures multiple LTE frequency points for the user equipment to measure at the same time, and determines the target frequency point and cell for switching or redirection based on the measurement report of each frequency point reported by the user equipment. When the measurement of multiple LTE frequency points is configured at the same time, the user equipment needs to loop through each frequency point according to the sequence of the configured LTE frequency points, and each frequency point occupies a measurement gap. For example, the first round of looping performs cell synchronization on all LTE frequency points; the second round of looping traverses all LTE frequency points, performs cell measurement on the LTE frequency points that have been cell synchronized, and performs cell synchronization on the LTE frequency points that have not been cell synchronized. In the scenario where the NR service cell signal changes rapidly, for example, from strong to weak, the user equipment needs to measure the LTE frequency and report the measurement result of the LTE frequency as soon as possible to trigger the cross-system switching or redirection from NR to LTE. However, for the above-mentioned prior art of performing multiple rounds of measurement on all LTE frequencies, the measurement and reporting of the LTE frequency will take a long time, which may affect the service flow of the user equipment, and even cause dropped calls and disconnection from the network, affecting the service experience.

The technical solution of the present invention is further described in detail below in conjunction with the drawings and specific embodiments of the specification. Unless otherwise defined, all technical and scientific terms used in the present invention have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The "and/or" used herein includes any and all combinations of one or more related listed items.

In existing mobile communications, inter-system LTE frequency measurement is usually used for the decision of inter-system switching and redirection from NR to LTE. The user equipment measures multiple LTE frequency points configured by the network equipment, and the network equipment decides whether to trigger inter-system switching or redirection from NR to LTE based on the measurement results reported by the user equipment. Among them, in the prior art, the user equipment measures multiple LTE frequency points configured by the network equipment by adopting a large-round cyclic measurement method for measuring all LTE frequency points. The measurement and reporting of LTE frequency points will take a long time. The network equipment may take a long time to receive the measurement results that meet the measurement result report requirements and implement the inter-system switching or redirection from NR to LTE, which may affect the service flow of the user equipment, and even cause dropped calls and disconnection from the network, affecting the service experience.

To this end, the present invention discloses a method for measuring a frequency point of an LTE system, comprising the following steps:

Get multiple LTE frequency points to be tested configured by the network device.

Based on the measurement strategy, measurement gaps are utilized to sequentially perform measurement tasks on the multiple LTE frequency points to be measured, and measurement results that meet the measurement result reporting requirements are reported to the network device; wherein, in the process of sequentially performing measurement tasks on the multiple LTE frequency points to be measured, the measurement task is performed on the next LTE frequency point only after the measurement task of the current LTE frequency point is completed.

It can be seen that the heterogeneous LTE frequency point measurement method disclosed in the present invention has changed the measurement mode compared with the prior art, mainly by utilizing the measurement gap, and performing measurement tasks on the multiple LTE frequency points to be measured in sequence according to the order of the multiple LTE frequency points allocated, wherein, in the process of performing measurement tasks on the multiple LTE frequency points to be measured in sequence, a cyclic measurement mode of a single LTE frequency point is adopted, that is, only after completing the measurement task of the current LTE frequency point, the measurement task is performed on the next LTE frequency point. The heterogeneous LTE frequency point measurement method can greatly reduce the shortest time for measuring and reporting the frequencies ranked in front, and timely report the measurement results of the measured LTE frequency points that meet the measurement result report requirements to the network equipment, so that the network equipment can trigger the heterogeneous system switching or redirection from NR to LTE accordingly, avoid dropped calls or disconnection of user equipment, and reduce the impact of the long measurement gap on the upper layer service performance.

The method for measuring a frequency point of LTE in a different system is based on a measurement strategy, and utilizes a measurement gap to perform measurement tasks on multiple LTE frequency points to be measured in sequence according to the order of multiple LTE frequency points allocated.

The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Please refer to Fig. 2, which is a schematic diagram of a flow chart of a method for measuring a frequency point of an LTE system in an embodiment of the present invention. The method for measuring a frequency point of an LTE system in an LTE system is applied to a user equipment.

Step S21, obtaining multiple LTE frequency points to be measured and measurement result reporting requirements configured by the network device.

In this embodiment, the network device may be, for example, an NR base station supporting NR standard communication. According to the communication protocol, under normal circumstances, a user device supporting NR standard communication needs to perform same-frequency, different-frequency, different-system LTE frequency point measurement, and L1-RSRP measurement in the radio resource control connection state. In the present invention, it mainly involves different-system LTE frequency point measurement. Therefore, in step S21, the user equipment receives multiple LTE frequency points to be measured from the network device configuration.

In the present invention, the measurement parameters of the user equipment for measuring the LTE frequency point of the heterogeneous system can be configured by the Radio Resource Control protocol layer (RRC), and the measurement process is performed by the physical layer (PHY), and the measurement of the physical layer is controlled by the radio resource control protocol layer.

Step S23, based on the measurement strategy and using the measurement gap, the measurement task is performed on multiple LTE frequency points to be measured in sequence with a single LTE frequency point as the measurement object, and the measurement result that meets the measurement result report requirement is reported to the network device.

In step S23, the user equipment uses the measurement gap to sequentially perform measurement tasks on multiple LTE frequency points to be measured, and performs the measurement task on the next LTE frequency point only after completing the measurement task of the current LTE frequency point.

In actual applications, a single LTE frequency point is used as the measurement object, and measurement tasks are performed on multiple LTE frequency points in sequence. For example, an LTE frequency point to be measured is selected in sequence, and the measurement task is performed on the selected LTE frequency point within a preset number of measurement gaps. After that, the next LTE frequency point to be measured is selected in sequence, and the measurement task is performed on the selected next LTE frequency point within a preset number of measurement gaps. In this way, the selection and measurement tasks of other LTE frequency points are performed to finally complete the measurement tasks of all LTE frequency points.

Among them, in the process of performing a measurement task on a certain LTE frequency point, if the measurement result of the measurement task is obtained and the measurement result meets the measurement result reporting requirements, the measurement result corresponding to the LTE frequency point is reported to the network device, and the network device triggers the inter-system switching or redirection from the NR standard communication network to the LTE standard communication network according to the LTE frequency point and its corresponding measurement result. Compared with the method of performing large-round cyclic measurement on all inter-system LTE frequency points in the prior art, the technical solution of the present invention can realize the rapid measurement of LTE frequency points and report the measurement results that meet the reporting requirements, so that the network device can complete the inter-system switching or redirection as soon as possible. It is particularly suitable for the scenario where the signal strength of the NR standard service cell changes rapidly (for example, the signal strength changes rapidly from strong to weak), which can effectively avoid the user equipment signal service deterioration, affect the service flow of the user equipment, and even cause dropped calls or disconnection from the network, and can improve the user's service experience.

Returning to step S23 , please refer to FIG. 3 , which is a detailed schematic diagram of step S23 in FIG. 2 in a certain embodiment.

As shown in FIG3 , the steps of performing a measurement task on one of the multiple LTE frequency points to be measured include:

Step S31, selecting an LTE frequency point to perform a measurement task. In this embodiment, the user equipment obtains multiple LTE frequency points to be measured configured from the network device and selects an LTE frequency point to perform a measurement task according to a frequency point selection order. The frequency point selection order may be determined according to the configuration information of the network device.

Step S33: performing frequency measurement on a selected LTE frequency within the allocated measurement gap.

In step S33, the allocated measurement gap can be used to perform frequency measurement on a selected LTE frequency.

In a single measurement gap, only one frequency point is processed. For example, in some embodiments, for a frequency point where cell synchronization has not been completed, only this frequency point is cell synchronized to detect unknown cells on this frequency point. In some embodiments, for a frequency point where cell synchronization has been completed, cell measurement is performed on this frequency point, and cell synchronization is performed on the one LTE frequency point to detect other unknown cells.

Regarding step S33, the content of frequency measurement on a selected LTE frequency varies in different embodiments.

In some embodiments, the frequency point measurement includes cell synchronization. For example, in some implementations, cell synchronization is performed on a selected LTE frequency point but cell measurement cannot be performed, and the situation where cell measurement cannot be performed includes but is not limited to performing cell synchronization on a selected LTE frequency point but failing to complete cell synchronization within a preset cell synchronization number threshold.

In some embodiments, the frequency point measurement includes cell synchronization combined with cell measurement. For example, in some implementations, cell synchronization is first performed on a selected LTE frequency point in a certain measurement gap, and after the cell synchronization is completed, cell measurement is performed on the selected LTE frequency point in another measurement gap.

For example, in some embodiments, the step of performing frequency measurement on the selected one LTE frequency within the allocated measurement gap includes:

In the mth measurement gap, it is determined whether the selected LTE frequency point has completed cell synchronization, wherein m is a positive integer.

If it is determined that the selected LTE frequency point has not completed cell synchronization, then in the mth measurement gap, cell synchronization is performed on the LTE frequency point.

If it is determined that the selected one LTE frequency point has completed cell synchronization, then in the mth measurement gap, cell measurement is performed on the one LTE frequency point, and cell synchronization is performed on the one LTE frequency point at the same time.

For the cell synchronization of LTE frequencies, it cannot be guaranteed that all LTE frequencies can complete cell synchronization. Therefore, in the present invention, a synchronization number threshold is also set to limit the number of times a single LTE frequency can continuously perform cell synchronization, that is, a single LTE frequency is allowed to continuously perform cell synchronization once or more times below the synchronization number threshold. When the synchronization number threshold is exceeded, the cell synchronization of the LTE frequency is stopped.

For example, in some embodiments, the step of performing frequency measurement on the selected one LTE frequency within the allocated measurement gap includes:

In the mth measurement gap, it is determined whether the selected LTE frequency point has completed cell synchronization, wherein m is a positive integer.

If it is determined that the selected LTE frequency point has not completed cell synchronization, then in the mth measurement gap, cell synchronization is performed on the LTE frequency point.

If cell synchronization is performed on the one LTE frequency point in the mth measurement gap but the cell is not synchronized, and the number of consecutive cell synchronizations performed on the one LTE frequency point is less than or equal to the synchronization number threshold, then in the (m+1)th measurement gap, the measurement task on the one LTE frequency point continues to be performed.

If cell synchronization is performed on the LTE frequency point in the mth measurement gap but failure to synchronize to the cell, and the number of consecutive cell synchronizations for the LTE frequency point is greater than the synchronization number threshold, the measurement task of the LTE frequency point is terminated, and subsequently in the m+1th measurement gap, the next LTE frequency point is selected to perform the measurement task.

Regarding the synchronization number threshold, it can be set according to the communication network environment and the requirements of the LTE frequency point measurement task. For example, in some embodiments, the synchronization number threshold is set to 1, which means that the number of continuous cell synchronizations for an LTE frequency point is limited to two times, that is, when the first cell synchronization is performed on a selected LTE frequency point in the first measurement gap, if the cell synchronization is completed in the first measurement gap, then in the second measurement gap, the cell measurement is performed on the LTE frequency point that has completed the cell synchronization; if the cell synchronization is not completed in the first measurement gap, then in the second measurement gap, the second cell synchronization is performed on the selected LTE frequency point; if the cell synchronization is completed in the second measurement gap, then in the third measurement gap, the cell measurement is performed on the LTE frequency point that has completed the cell synchronization; if the cell synchronization is not completed in the second measurement gap, then the measurement task for this LTE frequency point is terminated, and subsequently in the third measurement gap, the next LTE frequency point is selected to perform the measurement task.

Of course, there are other variations to the synchronization number threshold. For example, in some embodiments, the synchronization number threshold is set to 2, 3, 4, or other values. For example, the synchronization number threshold is set to 2, which means that the number of consecutive cell synchronizations for one LTE frequency point is limited to three times.

In addition, in step S33, cell measurement is performed on the LTE frequency point for which cell synchronization has been completed, that is, within a measurement gap, cell measurement is performed on a certain LTE frequency point, and cell synchronization is performed on the one LTE frequency point at the same time.

For the cell measurement of LTE frequency points, it cannot be guaranteed that all LTE frequency points can obtain corresponding measurement results. The reasons for failing to obtain corresponding measurement results include but are not limited to the interruption of the cell measurement process without measurement results or the completion of the cell measurement but without outputting the measurement results. Therefore, in the present invention, a measurement number threshold is also set to limit the number of times a single LTE frequency point can continuously perform cell measurement, that is, a single LTE frequency point is allowed to continuously perform one or more cell measurements under the measurement number threshold, and when the synchronization number threshold is exceeded, the cell measurement of the LTE frequency point is stopped.

For example, in some embodiments, the step of performing frequency measurement on the selected one LTE frequency within the allocated measurement gap includes:

In the mth measurement gap, a cell measurement is performed on a selected LTE frequency point.

If no measurement result is obtained after performing cell measurement on the selected LTE frequency point in the mth measurement gap, and when it is determined that the number of consecutive cell measurements on the LTE frequency point is greater than the measurement number threshold, the measurement task of the LTE frequency point is terminated, and in the m+1th measurement gap, the next LTE frequency point is selected to perform the measurement task.

If no measurement result is obtained after performing cell measurement on the LTE frequency point in the mth measurement gap, and when it is determined that the number of consecutive cell measurements on the LTE frequency point is less than or equal to the measurement number threshold but the LTE frequency point is not synchronized to the cell and the number of consecutive cell synchronizations is greater than the synchronization number threshold, then in the m+1th measurement gap, the next LTE frequency point is selected to perform the measurement task.

If no measurement result is obtained after performing cell measurement on the one LTE frequency point in the mth measurement gap, and when it is determined that the number of continuous cell measurements on the one LTE frequency point is less than or equal to the measurement number threshold and the one LTE frequency point has completed cell synchronization, then in the m+1th measurement gap, continue to perform the measurement task on the one LTE frequency point.

Regarding the measurement number threshold, it can be set according to the communication network environment and the requirements of the LTE frequency measurement task. For example, in some embodiments, the measurement number threshold is set to 1, which means that the number of continuous cell measurements for an LTE frequency is limited to two times, that is, when the first cell measurement is performed on a selected LTE frequency in the first measurement gap, if the corresponding measurement result is not obtained after the first cell measurement in the first measurement gap, it is determined whether the LTE frequency has completed cell synchronization; if it is determined that the first LTE frequency has completed cell synchronization, then the second cell measurement is continued for the LTE frequency in the second measurement gap; if it is determined that the first LTE frequency has not completed cell synchronization and continuous cell synchronization is performed, then the measurement result is not obtained after the first cell measurement in the first measurement gap ... When the number is less than or equal to the synchronization number threshold (for example, less than or equal to 1), a second cell measurement is performed on the LTE frequency point in the second measurement gap; if it is determined that the first LTE frequency point has not completed cell synchronization and the number of consecutive cell synchronizations is greater than the synchronization number threshold (for example, less than or equal to 1), the next LTE frequency point is selected to perform the measurement task in the second measurement gap; when a second cell measurement is performed on a selected LTE frequency point in the second measurement gap, if no corresponding measurement result is obtained after the second cell measurement in the second measurement gap, the next LTE frequency point is selected to perform the measurement task in the third measurement gap.

Of course, there are other variations to the measurement number threshold. For example, in some embodiments, the measurement number threshold is set to 2, 3, 4, or other values. For example, the measurement number threshold is set to 2, which means that the number of consecutive cell measurements for one LTE frequency point is limited to three times.

Step S35, obtaining the measurement result after completing the cell measurement at a selected LTE frequency point, and reporting the measurement result that meets the measurement result report requirement to the network device.

In the present invention, when a cell measurement is performed on a selected LTE frequency point and a corresponding measurement result is obtained after the cell measurement is completed, processing is performed based on the number of measurement results obtained by performing cell measurement on the selected LTE frequency point and the content of the measurement result.

In some embodiments, when a cell measurement is performed on a selected LTE frequency point and a corresponding measurement result is obtained after completing the cell measurement, when it is determined that the number of measurement results obtained by performing cell measurement on the LTE frequency point is less than or equal to a measurement result number threshold, the measurement items or measurement parameters in the measurement results are detected, and when it is detected that the measurement items or measurement parameters in the measurement results meet the conditions, the measurement result is determined to be valid.

In some embodiments, when a cell measurement is performed on a selected LTE frequency point and a corresponding measurement result is obtained after the cell measurement is completed, when it is determined that the number of measurement results obtained by performing cell measurement on the LTE frequency point is greater than a measurement result number threshold, the measurement result is directly recorded.

The threshold of the number of measurement results can be set according to the communication network environment and the requirements of the LTE frequency measurement task. For example, in some embodiments, the threshold of the number of measurement results is set to 1, which means that the number of times the corresponding measurement results are obtained after performing cell measurement on an LTE frequency is limited to two times, that is, if a cell measurement is performed on a selected LTE frequency in a certain measurement gap and the corresponding measurement result is obtained for the first time, the measurement items or measurement parameters in the measurement result are detected; if a cell measurement is performed on a selected LTE frequency in another subsequent measurement gap and the corresponding measurement result is obtained for the second time, the measurement result of this time is directly determined to be valid.

Of course, there are other variations of the measurement result number threshold. For example, in some embodiments, the measurement result number threshold is set to 2, 3, 4, or other values. Taking the measurement result number threshold as 2 as an example, it means that the measurement items or measurement parameters in the first two measurement results are detected, and the measurement results obtained for the third time and thereafter are not determined, and the measurement results of this time are directly determined to be valid.

In addition, in some embodiments, the measurement items or measurement parameters of the measurement results include but are not limited to Reference Signal Received Power (RSRP) and Signal to Interference plus Noise Ratio (SINR).

The reference signal received power RSRP is used to measure the power of a downlink reference signal received by a user equipment UE in a certain service cell, and can reflect the strength of a wireless signal between the user equipment UE and a network device, and is an important parameter for evaluating the quality of a wireless link.

The signal to interference plus noise ratio SINR refers to the ratio of the strength of a received useful signal to the strength of a received interference signal (noise and interference).

In the present invention, the step of detecting the measurement items or measurement parameters in the measurement result to determine whether the measurement result is valid includes: detecting whether the maximum value of the reference signal received power RSRP in the measurement result is greater than or equal to the reference signal received power threshold, and whether the maximum value of the signal to interference plus noise ratio SINR in the measurement result is greater than or equal to the signal to interference plus noise ratio threshold; if the maximum value of the reference signal received power RSRP in the measurement result is greater than or equal to the reference signal received power threshold and the maximum value of the signal to interference plus noise ratio SINR is greater than or equal to the signal to interference plus noise ratio threshold, the measurement result is determined to be valid.

In addition, in step S35, it also includes filtering the current measurement result determined to be valid, and judging whether the measurement result after filtering meets the measurement result reporting requirement configured by the network device. If it is judged that the measurement result after filtering meets the measurement result reporting requirement configured by the network device, the measurement result is reported to the network device.

In practical applications, for user equipment, the measurement task for the selected frequency point can be specifically performed by the physical layer PHY of the user equipment. After the physical layer performs cell measurement, the corresponding measurement result is obtained. The physical layer detects the measurement items or measurement parameters in the measurement result to determine whether the measurement result is valid. In the case where the measurement result is determined to be valid, the valid measurement result is recorded and sent to the Radio Resource Control protocol layer (Radio Resource Control, RRC). The radio resource control protocol layer filters the valid measurement result and determines whether the measurement result after filtering meets the measurement result report requirements. When it is determined that the measurement result after filtering meets the measurement result report requirements, the radio resource control protocol layer reports the measurement report containing the measurement result and sends it to the network device.

The following describes in detail the operation flow of the heterogeneous LTE frequency point measurement method in an example of the present invention in conjunction with the accompanying drawings.

Please refer to FIG. 4 , which is an operation flow chart of an example of a method for measuring frequency points of LTE in a different system according to the present invention.

Step S401, obtaining N LTE frequency points configured by the network device and measurement result reporting requirements. In this example, the N LTE frequency points configured by the network device may be marked as: F0, F1, ..., FN-2, FN-1.

Step 403, initialize various parameters, n = 0, F = Fn, m = 0, i = 0, j = 0, k0 = 0, k1 = 0, ..., kN-1 = 0. Among them, Fn represents the LTE frequency, n represents the sequence number of the LTE frequency, m represents the sequence number of the measurement gap, i represents the number of continuous synchronizations, j represents the number of continuous measurements, and kn represents the number of measurement results corresponding to the LTE frequency Fn.

Step S405, determine whether the mth measurement gap has arrived. If it is determined that the mth measurement gap has arrived, proceed to step S407; if it is determined that the mth measurement gap has not arrived, continue waiting.

Step S407, judging whether the selected frequency point F has completed cell synchronization. If it is judged that the selected frequency point F has completed cell synchronization, proceed to step S409; if it is judged that the selected frequency point F has not completed cell synchronization, proceed to step S411.

Step S411, performing cell synchronization on the selected frequency point F, and at the same time, the number of consecutive synchronization times i is increased by 1.

Step S413, determine whether the selected frequency point F has completed cell synchronization. If it is determined that the selected frequency point F has completed cell synchronization, return and wait for the next measurement gap. If it is determined that the selected frequency point F has not completed cell synchronization, then in step S415, determine whether the number of consecutive synchronizations i corresponding to the selected frequency point F is less than or equal to the synchronization number threshold. The synchronization number threshold can be set to 1, for example. If it is determined that the number of consecutive synchronizations i corresponding to the selected frequency point F is less than or equal to the synchronization number threshold, return and wait for the next measurement gap. If it is determined that the number of consecutive synchronizations i corresponding to the selected frequency point F is greater than the synchronization number threshold, end the measurement task of the current LTE frequency point F, select the next LTE frequency point and initialize the various parameters related to the next LTE frequency point, and wait for the next measurement gap.

Step S409, performing cell measurement on the selected LTE frequency point, and at the same time, performing cell synchronization on the selected LTE frequency point to detect other unknown cells, and at the same time, the number of consecutive measurements j is increased by 1 and the number of consecutive synchronizations i is increased by 1.

Step S417, determine whether there is a measurement result. If it is determined that there is a measurement result, proceed to step S419, and add 1 to the number of measurement results kn.

Step S421, determine whether the number of measurement results kn is less than or equal to the measurement result number threshold. The synchronization number threshold can be set to 1, for example. If it is determined that the number of measurement results kn is less than or equal to the measurement result number threshold, proceed to step S423. If it is determined that the number of measurement results kn is greater than the measurement result number threshold, proceed to step S425.

Step S423, determining whether the current measurement result is valid.

In some embodiments, determining whether the measurement result is valid may specifically include: detecting the measurement items or measurement parameters in the measurement results, detecting whether the maximum value of the reference signal received power RSRP in the measurement results is greater than or equal to the reference signal received power threshold, and whether the maximum value of the signal to interference plus noise ratio SINR in the measurement results is greater than or equal to the signal to interference plus noise ratio threshold.

If it is detected that the maximum value of the reference signal received power RSRP in the measurement result is greater than or equal to the reference signal received power threshold, and the maximum value of the signal to interference plus noise ratio SINR in the measurement result is greater than or equal to the signal to interference plus noise ratio threshold, then the measurement result is determined to be valid and proceeds to step S425.

If it is detected that the measurement result cannot satisfy that the maximum value of the reference signal received power RSRP is greater than or equal to the reference signal received power threshold, and the maximum value of the signal to interference plus noise ratio SINR in the measurement result is greater than or equal to the signal to interference plus noise ratio threshold, then the measurement result is determined to be invalid and go to step S429.

Step S425, recording the measurement result of this time.

Subsequently, it also includes: filtering the measurement results determined to be valid, judging whether they meet the measurement result reporting requirements configured by the network device, and reporting the measurement results to the network device if it is judged that the measurement result reporting requirements configured by the network device are met.

Subsequently, the measurement task of the current LTE frequency F is terminated, the next LTE frequency is selected and various parameters related to the next LTE frequency are initialized, and at the same time, the next measurement gap is waited for.

Returning to step S417, if it is determined that there is no measurement result, the process proceeds to step S427 to determine whether the number of consecutive measurements i corresponding to the selected frequency point F is less than or equal to a measurement number threshold. The measurement number threshold can be set to 1, for example.

If it is determined that the number of consecutive measurements j corresponding to the selected frequency F is greater than the measurement number threshold, the measurement task of the current LTE frequency F is terminated, the next LTE frequency is selected and the various parameters related to the next LTE frequency are initialized, and at the same time, the next measurement gap is waited for.

If it is determined that the number of consecutive measurements j corresponding to the selected frequency point F is less than or equal to the measurement number threshold, the process proceeds to step S429.

Step S429, determine whether the selected frequency point F has completed cell synchronization. If it is determined that the selected frequency point F has completed cell synchronization, return and wait for the next measurement gap. If it is determined that the selected frequency point F has not completed cell synchronization, proceed to step S431.

In step S431, it is determined whether the number of continuous synchronizations i corresponding to the selected frequency point F is less than or equal to the synchronization number threshold. The synchronization number threshold can be set to 1, for example. If it is determined that the number of continuous synchronizations i corresponding to the selected frequency point F is less than or equal to the synchronization number threshold, return and wait for the next measurement gap. If it is determined that the number of continuous synchronizations i corresponding to the selected frequency point F is greater than the synchronization number threshold, the measurement task of the current LTE frequency point F is terminated, the next LTE frequency point is selected and the various parameters related to the next LTE frequency point are initialized, and at the same time, the next measurement gap is waited.

It can be seen from the above that the inter-system LTE frequency measurement method disclosed in the present invention adopts a cyclic measurement method of a single LTE frequency, that is, only after completing the measurement task of the current LTE frequency, the measurement task of the next LTE frequency is performed, until the measurement tasks of all LTE frequency are completed in sequence, which can greatly reduce the shortest time for measuring and reporting the frequencies in the front order, and report the measurement results of the measured LTE frequency that meet the measurement result reporting requirements to the network device in time, so that the network device can trigger the inter-system switching or redirection of the new air interface NR to LTE accordingly, avoid dropped calls or disconnection of user equipment, and reduce the impact of the long measurement gap on the upper layer service performance.

As can be seen from the embodiment shown in Figure 4, in the present invention, measurement gaps are utilized to sequentially perform measurement tasks on multiple LTE frequency points to be measured. Wherein, in the process of sequentially performing measurement tasks on multiple LTE frequency points to be measured, the measurement task is performed on the next LTE frequency point only after the measurement task of the current LTE frequency point is completed. Here, completing the measurement task of the current LTE frequency point includes but is not limited to any of the following situations: no measurement result is obtained, the measurement result is obtained but the measurement result is invalid, the measurement result is obtained and the measurement result is valid but does not meet the measurement result report requirements, and the measurement result is obtained and the measurement result is valid and meets the measurement result report requirements, wherein, for the measurement result obtained and the measurement result is valid and meets the measurement result report requirements, the measurement report containing the measurement result is reported to the network device, so that the network device can trigger the new air interface NR to LTE inter-system switching or redirection and other operations accordingly.

Please refer to Fig. 6, which is a schematic diagram of a flow chart of a method for measuring a frequency point of an LTE system in an embodiment of the present invention. The method for measuring a frequency point of an LTE system in an LTE system is applied to a network device.

Step S61: Send the configured multiple LTE frequency points to be measured and the measurement result report request to the user equipment so that the user equipment can perform the measurement task on the multiple LTE frequency points.

In this embodiment, the network device may be, for example, an NR base station that supports NR standard communication. According to the communication protocol, under normal circumstances, a user device that supports NR standard communication needs to perform same-frequency, different-frequency, different-system LTE frequency point measurement, and L1-RSRP measurement in the radio resource control connection state. In the present invention, it mainly involves different-system LTE frequency point measurement. Therefore, in step S61, the network device sends the configured multiple LTE frequency points to be measured and the measurement result report requirement to the user equipment for the user equipment to perform measurement tasks on the multiple LTE frequency points.

When the user equipment performs the measurement task on the multiple LTE frequency points, it is mainly based on the measurement strategy, using the measurement gap, and performing the measurement task on the multiple LTE frequency points to be measured in sequence according to the order of the multiple allocated LTE frequency points. In the process of performing the measurement task on the multiple LTE frequency points to be measured in sequence, a cyclic measurement method of a single LTE frequency point is adopted, that is, the measurement task is performed on the next LTE frequency point only after the measurement task of the current LTE frequency point is completed.

After the network device receives the measurement result related to the LTE frequency point that meets the measurement result report requirements uploaded by the user equipment, it triggers the user equipment to switch or redirect the system from NR to LTE to continue to provide communication services for the user equipment.

When the user equipment performs the measurement task on the multiple LTE frequency points, it is mainly based on the measurement strategy, using the measurement gap, and sequentially performing the measurement task on the multiple LTE frequency points to be measured in the order of the allocated multiple LTE frequency points. In the process of sequentially performing the measurement task on the multiple LTE frequency points to be measured, a cyclic measurement method of a single LTE frequency point is adopted, that is, the measurement task is performed on the next LTE frequency point only after the measurement task of the current LTE frequency point is completed.
