However, the quality of service provided by the network device to the terminal device based on the measurement report still has poor quality.

The application provides a communication method and a communication device, which can enable terminal equipment to select at least one of a plurality of pieces of filter information issued by network equipment as target filter information for filtering, so that the service quality provided by the network equipment can be improved.

In a first aspect, an embodiment of the present application provides a communication method, which may include: receiving a first filtering information set of target measurement parameters from a network device, the first filtering information set comprising a plurality of first filtering information, the first filtering information being used for filtering first measurement results of the target measurement parameters; then, selecting target filtering information from the first filtering information set, wherein the target filtering information is at least one of a plurality of first filtering information; then, the first measurement result of the target measurement parameter is filtered based on the target filtering information.

In one possible implementation, the method may be performed by the terminal device or by a chip in the terminal device.

According to the communication method, the network equipment sends the first filtering information set of the target measurement parameters to the terminal equipment, the first filtering information set comprises a plurality of different first filtering information, at least one of the first filtering information is selected as the target filtering information by the terminal equipment, and then the first measuring result of the target measurement parameters measured by the terminal equipment is filtered by the target filtering information.

With reference to the first aspect, in one possible implementation manner, selecting target filtering information from the first filtering information set includes:

Selecting target filtering information from the first filtering information set based on the related information of the terminal equipment; wherein the target filtering information is one of the first filtering information sets, and the related information comprises information affecting the cellular communication quality of the terminal equipment.

According to the communication method, the terminal equipment selects the target filtering information from the first filtering information set based on the relevant information of the terminal equipment, and the selected target filtering information is matched with the condition of the terminal equipment, so that the accuracy of the selected target filtering information can be improved, and the filtering effect is improved.

With reference to the first aspect, in one possible implementation manner, the filtered first measurement result is obtained based on the first measurement result, the target filter coefficient, and a second measurement result, where the second measurement result includes a measurement result obtained before the first measurement result; and the target filter information includes target filter coefficients or target filter parameters for determining the target filter coefficients.

According to the communication method, the current measurement result (for example, the first measurement result) can be filtered by combining the historical measurement result (for example, the second measurement result), and therefore the filtering effect can be improved.

With reference to the first aspect, in one possible implementation manner, if the currently used target filtering information is the same as the filtering information used in the previous filtering, the first measurement result after filtering satisfies the following formula:

。

wherein Fn represents the filtered first measurement result, mn represents the first measurement result, fn-1 represents the second measurement result, the second measurement result includes the last measurement result of the first measurement result, and a represents the target filter coefficient.

With reference to the first aspect, in one possible implementation manner, if the currently used target filtering information is different from the filtering information used in the previous filtering, the first measurement result after filtering satisfies the following formula:

In order to facilitate understanding of the embodiments of the present application, the following detailed description of the related terms related to the embodiments of the present application will be given with reference to fig. 2 and 2.

1. Cell: also called a cell, refers to an area covered by one of base stations or a part of a base station (sector antenna) in a cellular mobile communication system, in which a mobile station can reliably communicate with the base station through a wireless channel.

2. Cell handover: the process by which a UE transfers from one cell to another is called handover.

This is typically due to the mobile device moving into the coverage of a new cell or due to a change in network conditions, such as congestion or a decrease in signal quality.

3. Measurement report: the third generation partnership project (3rd generation partnership project,3GPP) proposes a set of predefined measurement reporting mechanisms that are performed by the UE. And the base station judges whether the cell switching condition is met or not through a measurement report reported by the UE. The measurement report may be generally reported according to measurement results corresponding to measurement parameters (also called measurement quantity) such as reference signal received power (reference signal received power, RSRP), reference signal received quality (reference signal received quality, RSRQ), signal-to-interference and noise ratio (signal to interference noise ratio, SINR), and the like (received signal strength indication, received signal strength indication, RSSI). The reporting is performed periodically and based on event triggering, the periodicity is mainly to report the strongest coverage cell, that is, the network acquisition coverage condition, and the event triggering is generally handover (possibly redirection, etc.).

Before reporting the measurement report, the UE will perform L1 filtering and L3 filtering on the measurement result. LI filtering can be performed by the UE physical layer without user configuration, and is mainly used for eliminating the influence of fast fading on the measurement result. The L3 filtering mainly carries out smooth filtering on shadow fading and a small amount of fast fading burrs, and provides better measurement data for event judgment.

In filtering, a filter coefficient is generally selected for filtering. Taking L3 filtering as an example, in the related art, when L3 filtering is performed, generally, a network device side configures an L3 filter coefficient to a terminal device. The appropriate L3 filter coefficient may achieve a good compromise between measurement accuracy and tracking speed, so it is particularly important for L3 filtering to select an appropriate L3 filter coefficient. In configuring the L3 filter coefficients, the network device side configures a plurality of filter parameters k through a radio resource control (radio resource control, RRC) message, and then, for a given measurement quantity (for example, RSRP, RSRQ or SINR) of each measurement object (also called cell), the network device side designates one of the parameters k for use, so that the terminal device can determine the L3 filter coefficients based on the parameters k, and further perform measurement results based on the L3 filter coefficients.

For example, for RSRP, the network device side may specify that it L3 filters the RSRP measurement using the filter parameter A1. For RSRQ, the network device side would specify that it L3 filters the measurement of RSRQ using the filter parameter B1. For SINR, the network device side would specify that it L3 filters the SINR measurement using the filter parameter C1.

However, since the network device does not adjust the L3 filter coefficients in good time according to the UE situation, the measurement result of RSRP/RSRQ is not expected, which affects the performance of radio resource management (radio resource management, RRM) and the user experience, and thus results in the quality of service provided by the network device.

In view of this, the present application provides a communication method and apparatus, for each measurement parameter, a network device may send a set of filtering information of the measurement parameter to a terminal device, where one set of filtering information of the measurement parameter includes a plurality of pieces of filtering information of the measurement parameter, so that the terminal device may select, according to an actual situation, part or all of the filtering information from the plurality of pieces of filtering information, and filter a measurement result of the measurement parameter, so as to improve quality of service provided by the network device.

For RSRP, the set of filtering information issued by the network device side may include a filter parameter A1 and a filter parameter A2, and then, for the measurement result of RSRP, the terminal device may select at least one filter parameter from the filter parameter A1 and the filter parameter A2 to filter the measurement result of RSRP.

For the RSRQ, the filter information set issued by the network device side may include a filter parameter B1 and a filter parameter B2, and then, for the measurement result of the RSRQ, the terminal device may select at least one filter parameter from the filter parameter B1 and the filter parameter B2 to filter the measurement result of the RSRQ.

For example, for SINR, the filter information set issued by the network device side may include a filter parameter C1 and a filter parameter C2, and for the measurement result of SINR, the terminal device may select at least one filter parameter from the filter parameter C1 and the filter parameter C2 to filter the measurement result of SINR.

The specific form and number of the devices shown therein are merely examples and should not be construed as limiting the practice of the methods provided herein in any way.

It should be understood that the above examples are part of the measurement parameters, and the filtering information needed to report the measurement results may be considered as the measurement parameters of the embodiments of the present application, and are not limited herein.

The first filtering information is used for filtering a first measurement result of the target measurement parameter. Alternatively, the first filtering information may include a first filtering coefficient or a first filter parameter for determining the first filtering coefficient. In particular, a certain functional relation may be fulfilled between the first filter coefficient and the first filter parameter.

In this embodiment of the present application, the first filtering information set may serve to provide a basis for selecting filtering information to the terminal device, so that the terminal device filters the measurement result based on the filtering information. Wherein the plurality of first filtering information may be different from each other.

It will be appreciated that there may be the same or different filter parameters between the first set of filter parameters for different target measurement parameters. For example, taking RSRP and RSRQ as examples, if the first filter parameter includes a first filter parameter set, the first filter parameter set of RSRP includes a filter parameter A1 and a filter parameter A2, and the first filter parameter set of RSRQ includes a filter parameter B1 and a filter parameter B2, which may be different from each other, or may be the same for the filter parameter A1 and the filter parameter B1, and/or the filter parameter A2 and the filter parameter B2, which are determined according to the filter parameters actually issued by the network device, which is not limited herein.

Optionally, the first set of filter parameters may be a set pre-configured in the network device; or a set of network devices determined based on some information, for example based on current or historical information of the terminal device. The current information may include, but is not limited to, at least one of a current speed of the terminal device or a current cellular communication quality, etc.; the historical information may include, but is not limited to, at least one of a historical speed of the terminal device or a historical cellular communication quality, etc. Furthermore, the set is determined, for example, based on information of cells covered by the terminal device. The information of the cell may include, but is not limited to, at least one of a congestion condition or a number of reconnections, etc., and is not limited herein.

S204, the terminal equipment selects target filtering information from the first filtering information set.

Wherein the target filtering information is at least one of the plurality of first filtering information. Alternatively, the terminal device may randomly select at least one of the plurality of first filtering information, or select at least one of the plurality of first filtering information according to a policy.

It should be noted that, even if each measurement parameter needs to report a measurement result, the network device may send, according to an actual situation, a first filtering information set of some or all measurement parameters to the terminal device, so, for some or all measurement parameters that receive the first filtering information set, the terminal device may select, from the received first filtering information set, target filtering information for filtering measurement results of some or all measurement parameters; and for a part of the measurement parameters for which the specified filtering information is received, the part of the measurement parameters are filtered using the specified filtering information.

Taking the example that the first filter parameters include first filter parameters, assuming that the network device sends a first filter parameter set of RSRP and a first filter parameter set of RSRQ to the terminal device, at least one of the filter parameters A1 and A2 may be selected to filter the measurement result of RSRP, and similarly at least one of the filter parameters B1 and B2 may be selected to filter the measurement result of RSRQ; assuming that the network device sends a first set of filter parameters of the RSRP to the terminal device and specifies that the RSRQ is filtered using the filter parameters B1, at least one of the filter parameters A1 and A2 may be selected to filter the measurement of the RSRP and the measurement of the RSRQ is filtered using the filter parameters B1.

It should be understood that the first filter coefficient set may refer to the description of the first filter parameter set, which is not described herein.

S206, the terminal equipment filters the first measurement result of the target measurement parameter based on the target filtering information.

The filtering method may be a filtering method such as L1 filtering or L3 filtering, and the filtering method may be related to a specific measurement parameter, which is not limited herein. In this embodiment, the first measurement result may be a result obtained by the terminal device measuring the target measurement parameter of at least one cell. Alternatively, the first measurement may reflect the value of the target measurement parameter at the first moment. The first time may be the current time.

For example, if the first filter information includes a first filter coefficient, the terminal device selects a target filter coefficient of the plurality of first filter coefficients, that is, the selected target filter information includes a target filter coefficient, the terminal device may filter the first measurement result based on the target filter coefficient. If the first filtering information includes first filter parameters, the terminal device selects a plurality of first filter parameters, that is, the target filtering information includes target filter parameters, so that the terminal device can determine a target filtering coefficient based on the target filter parameters, and further filter the first measurement result based on the target filtering coefficient.

In this embodiment of the present invention, for each measurement parameter, the network device may send a filter information set of the measurement parameter to the terminal device, where the filter information set of one measurement parameter includes multiple filter information of the measurement parameter, so the terminal device may select, according to an actual situation, part or all of the filter information from the multiple filter information, to filter a measurement result of the measurement parameter, that is, for each measurement parameter, the terminal device may select, for each measurement parameter, at least part of the filter information from the corresponding multiple filter information, thereby may select, according to an actual situation, more accurate filter information to perform filtering, thereby improving accuracy of the filtered measurement result, and further enabling the network device to perform radio resource management based on the more accurate measurement result, and further improving quality of service provided by the network device.

In the following, an example of one of the target measurement parameters is taken, for example, RSRP, RSRQ, SINR or RSSI, to describe in detail how to select the target filtering information in the first filtering information set, and the manner in which each target measurement parameter selects the target filtering information may refer to the following description of the embodiments, which will not be repeated herein.

In a possible implementation manner, S204, a manner of selecting, by the terminal device, the target filtering information from the first filtering information set may include:

the target filter information is selected from the first set of filter information based on the relevant information of the terminal device.

Wherein the target filtering information is one of the first filtering information sets. For example, the first set of filtering information includes filtering information 1 and filtering information 2, and the target filtering information may be filtering information 1 or filtering information 2. The related information includes information affecting the cellular communication quality of the terminal device. Illustratively, the related information may include, but is not limited to, at least one of a mobile speed value, a reference signal received power, RSRP, a received signal strength indication, RSSI, a reference signal received quality, RSRQ, value, or a signal to interference and noise ratio, SINR, value.

Optionally, the related information includes at least one of a mobile speed value of the terminal device, a reference signal received power RSRP value, a received signal strength indication RSSI value, a reference signal received quality RSRQ value, or a signal to interference plus noise ratio SINR value.

Taking the example that the related information includes a moving speed value, in general, the larger the moving speed of the terminal device, the larger the influence on the cellular communication quality of the terminal device may be, for example, the greater the moving speed of the terminal device, the worse the cellular communication quality of the terminal device may be. Therefore, the relation between the related information and the target filter information is related to the degree of influence of the target filter information on the first measurement result. For example, if the value of the target filtering information is larger, the correlation between the first measurement result and the filtered first measurement result is larger, that is, the influence of the first measurement result on the filtered first measurement result is larger, the moving speed value is larger, and the value of the target filtering information is smaller. Also, as an example, if the value of the target filtering information is larger, the correlation between the first measurement result and the filtered first measurement result is smaller, that is, the influence of the first measurement result on the filtered first measurement result is smaller, the moving speed value is larger, and the value of the target filtering information is larger.

In this embodiment, the target filtering information is selected from the first filtering information set based on the relevant information of the terminal device, that is, the target filtering information selected by combining the relevant information of the terminal device is more matched with the condition of the terminal device, so that the accuracy of the selected target filtering information can be improved, and the accuracy of the filtered measurement result can be improved.

Alternatively, the plurality of first filtering information in the first filtering information set may be arranged arbitrarily, or may be arranged according to a certain rule, for example, arranged in a sequence from large to small or from small to large, which is not limited herein.

For ease of understanding, the following embodiments will be described in detail taking an example in which the first filter information includes the first filter parameter. For example, taking an example that the first filtering information includes the first filter parameters, an arrangement manner of the plurality of first filter parameters in the first filter parameter set may be as follows:

. Wherein M may represent the total number of filter parameters in the first set of filter parameters, M being an integer not smaller than 2. In this example, ∈>Can be arranged in sequence from small to large.

In this embodiment, alternatively, if the target filter parameters are determined based on the moving speeds, each filter parameter k corresponds to one moving speed. For example, each filter parameter k may be associated with a movement speed identifier, from which a movement speed corresponding to the filter parameter k may be determined.

In one possible implementation, the speed corresponding to each filter parameter k may be compared with the moving speed of the terminal device based on the moving speed value of the terminal device, and then the filter parameter k having the closest corresponding speed to the moving speed of the terminal device is used as the target filter parameter k. For example, if the filter parameter k1 corresponds to the velocity V1, the filter parameter k2 corresponds to the velocity V2, and the filter parameter k3 corresponds to the velocity V3, the moving velocity of the terminal device is V At this time, the speed corresponding to the filter parameter k2 is closest to the moving speed of the terminal device, and therefore, the filter parameter k2 can be selected as the target filter parameter.

It should be understood that, if the target filter parameter is determined based on the reference signal received power RSRP value, the received signal strength indication RSSI value, the reference signal received quality RSRQ value, or the signal to interference plus noise ratio SINR value, each filter parameter k may also correspond to one of the reference signal received power RSRP value, the received signal strength indication RSSI value, the reference signal received quality RSRQ value, or the signal to interference plus noise ratio SINR value, and the value corresponding to each filter parameter k may be determined according to the relevant information according to which the target filter parameter is selected, which is not described herein.

In another possible implementation manner, if the target filter parameter is at least two of the plurality of first filter parameters, the at least two target filter parameters may be fused to obtain a fused target filter parameter, and then the fused target filter parameter is used to filter the first measurement result. Alternatively, the fusion may be performed by calculating an average value or a weighted average value of at least two pieces of target filtering information, which is not limited herein. Alternatively, at least two filter parameters k having a corresponding speed closest to the moving speed of the terminal device may be selected as the target filter parameter k.

If the first filtering information includes the first filtering coefficient, an arrangement manner of the plurality of first filtering coefficients in the first filtering coefficient set may be as follows:

. The first filter coefficient set may refer to a description of the first filter parameter set, which is not described herein.

In this embodiment, alternatively, if the target filter coefficient is determined based on the moving speed, each filter coefficient a corresponds to one moving speed.

It can be understood that the manner of determining the target filter coefficient from the plurality of first filter coefficients may refer to the manner of determining the target filter parameter from the plurality of first filter parameters, which is not described herein.

How the filtering is performed is described in detail below.

In step S206, after the terminal device filters the first measurement result of the target measurement parameter based on the target filtering information, a filtered first measurement result may be obtained.

In one possible implementation, the filtered first measurement is obtained based on the first measurement, the target filter coefficient, and a second measurement, the second measurement including a measurement obtained prior to the first measurement.

In this embodiment, the second measurement result may be a result obtained by the terminal device measuring the target measurement parameter of at least one cell at the second time. The second moment is earlier than the first moment. Optionally, in this embodiment, if the target filter coefficient is larger, the correlation between the filtered first measurement result and the first measurement result is larger, and the target filter coefficient is larger, the correlation between the filtered first measurement result and the second measurement result is smaller. In addition, the larger the target filter coefficient is, the smaller the correlation between the first measurement result after filtering and the first measurement result is, and the larger the target filter coefficient is, the larger the correlation between the first measurement result after filtering and the second measurement result is.

It should be appreciated that the relationship between the filtered first measurement, the target filter coefficient, and the second measurement is related to a specific filtering manner and is not limited herein.

Illustratively, the filtered first measurement satisfies the following relationship with the first measurement, the target filter coefficient, and the second measurement:

。

In the embodiment of the application, when the first measurement result is filtered, the second measurement result is considered, that is, the history measurement result is considered, so that the first measurement result can be smoothed by combining with the history measurement result, and the obtained filtered first measurement result is more accurate.

In one possible implementation manner, the terminal device may select different filtering information to perform filtering in different situations, for example, when related information such as a moving speed of the terminal device changes, the selected filtering information may also change, so the following embodiments respectively describe situations that the selected filtering information changes, and the selected filtering information does not change, and so on.

First, a case where the filtering information selected by the terminal device is not changed will be described.

In this embodiment, if the filtering information selected by the terminal device is not changed, it is indicated that the relevant information of the terminal device is not changed or the amplitude of the change is not large, that is, the first measurement result and the previous second measurement result are measurement results obtained respectively under the condition that the terminal device is relatively similar, so the filtering of the first measurement result can be smoothed based on the second measurement result, and therefore, the filtered first measurement result can be determined by the following formula:

。

alternatively, if the target filtering information is the same as the filtering information used in the filtering of the second measurement result, in other words, if the currently used target filtering information is the same as the previous filtering information, for example, the filtering information used in the previous filtering is the same, it may be considered that the filtering information selected by the terminal device has not changed. For example, if the target filter parameter is k1 and the second measurement result is also the filter parameter k1 used in filtering, the filtering information selected by the terminal device is unchanged. Also, for example, if the target filter coefficient is a1 and the filter coefficient a1 is also used in filtering the second measurement result, the filtering information selected by the terminal device is unchanged.

Next, a case where the filtering information selected by the terminal device is changed will be described.

In this embodiment, if the target filtering information is different from the filtering information used when the second measurement result is filtered, in other words, if the currently used target filtering information is different from the previous filtering information, for example, different from the filtering information used in the previous filtering, the filtering information selected by the terminal device changes, which means that the change amplitude of the relevant information of the terminal device is larger or has a certain change, that is, the first measurement result and the previous second measurement result are measurement results obtained when the situation of the terminal device differs greatly, respectively, so that when the second measurement result participates in the smoothing of the first measurement result, there may be a larger interference to the first measurement result.

Thus, in one possible implementation, the filtered first measurement may be determined by the following formula:

。

in this embodiment, when the filtering information changes, the measurement result should be reinitialized, that is, the measurement result obtained by the old filtering information is not used any more, and the measurement result obtained by the new filtering information is smoothed. For example, when the filtering information used by the first measurement result and the second measurement result are different, the second measurement result is no longer used to smooth the first measurement result. In other words, when new filter information is used, fn-1=0 is made.

In the embodiment of the application, if the filtering information changes, the measurement result is reinitialized, so that the influence of the history measurement result on the current measurement result can be reduced, the calculated amount of filtering is reduced, and the calculation force resource required during filtering is saved.

In another possible implementation, the filtered first measurement may be determined by the following formula:

。

where p represents a constant or variable, that is, the value of p may be fixed or variable. Optionally, p is any number between 0 and 1 to reduce the effect of Fn-1 on Fn. In this embodiment, p is a fixed value between 0 and 1, so that the influence of Fn-1 on Fn can be reduced fixedly, or a variable value determined according to the actual situation, so that the influence of Fn-1 on Fn can be regulated dynamically.

Optionally, the second filtering measurement result may be a result obtained by directly measuring the measurement result by the terminal, or may be a result obtained by filtering the measurement result by the terminal, which is not limited herein.

The relation between the filter coefficient and the filter parameter may be a positive correlation, for example, the larger the filter parameter is, the larger the filter coefficient is. In addition, there may be a negative correlation between the filter coefficients and the filter parameters, for example, the larger the filter parameters, the smaller the filter coefficients, etc.

By way of example only, and not by way of limitation,. In this example, k represents a filter parameter, such as a filter coefficient being smaller as the filter parameter is larger.

Yet another exemplary embodiment of the present invention is a method of manufacturing a semiconductor device,. In this example, the larger the filter parameters, the larger the filter coefficients.

It should be understood that the relationship between the filter coefficients and the filter parameters may be determined according to the actual situation, for example, according to a specific filtering manner, and is not limited herein.

It should be understood that if the second measurement result is the last measurement result before the first measurement result, the filtering information in the previous filtering may be filtering information for filtering the second measurement result.

In one possible implementation, the specific value of p may be determined based on information at the time of the first measurement filtering and information at the time of the historical measurement. Alternatively, the specific value p1 of p may be determined based on the target filtering information and the history filtering information, and/or based on the first related information and the second related information. For example, the specific value p1 of p is determined based on the target filtering information used at the time of the first measurement result filtering and the filtering information used at the time of the second measurement result filtering, and/or based on the related information of the terminal device at the time of the first measurement result filtering and the related information of the terminal device at the time of the second measurement result filtering.

In one example, a particular value of p may be determined based on a difference between the target filter information and the historical filter information, e.g., the greater the difference, the smaller the p. In addition, a specific value of p may also be determined based on the ratio between the target filtering information and the historical filtering information. The larger one of the target filtering information and the history filtering information may be used as a denominator, and the smaller one may be used as a numerator. Alternatively, the smaller the ratio, the smaller the p, for example, the ratio may be taken as a specific value of p.

In another example, the specific value of p may be determined based on a difference or ratio of the first related information and the second related information. For example, taking the example that the related information comprises RSRP values, a specific value of p may be determined based on the difference between the first RSRP value and the second RSRP value, e.g. the larger the difference the smaller the p. Or a ratio between the first RSRP value and the second RSRP value, to determine a specific value of p. The larger one of the first RSRP value and the second RSRP value may be used as a denominator, and the smaller one may be used as a numerator. Alternatively, the smaller the ratio, the smaller the p, for example, the ratio may be taken as a specific value of p.

In another example, one of the values may be determined based on the target filtering information and the historical filtering information, then the other value may be determined based on the first correlation information and the second correlation information, and then the values may be fused to obtain the value that is ultimately used to adjust the impact of Fn-1.

In the embodiment of the application, if the filtering information changes, the influence of Fn-1 on Fn is reduced, but the influence of Fn-1 is not directly ignored, so that the accuracy of filtering the measurement result can be improved.

In one possible implementation, the communication method may further include:

s208, the terminal equipment sends first information to the network equipment, wherein the first information comprises target filtering information and/or an index of the target filtering information.

In the embodiment of the application, the terminal device may send the target filtering information to the network device, so that the terminal device may timely learn the target filtering information selected by the network device, and then, based on the target filtering information, may approximately determine the current moving speed of the terminal device, the change condition of the moving speed, and the like, so that the terminal device may timely adjust a dynamic (mobility) policy for the terminal device. For example, the network device may consider the speed corresponding to the reported target filtering information as the moving speed of the terminal device, or may consider the moving speed of the terminal device after calibrating based on the speed corresponding to the target filtering information, and the calibrating manner may be calibrated by combining historical speed change information of the terminal device or change information of channel quality information (for example, RSRP) and the like.

Optionally, before, simultaneously with, or after reporting the measurement result of RSRP, RSRQ, or the like, the selected target filtering information may be reported to the network device through a MAC-control element (MAC-CE).

In one example, if it is determined that the speed of the terminal device becomes large based on the target filtering information, when the UE needs to make handover, the network device needs to prepare handover procedure earlier than before, such as sending handover request to a neighbor cell (neighbor cell) earlier, etc.

In another example thereof, if it is determined that the moving speed of the terminal device has changed based on the target filter information, a new filter information set, for example, a second filter information set is issued.

In another possible implementation manner, the network device may also predict the moving speed of the terminal device based on the change condition of the channel quality information reported by the terminal device, but by the way that the terminal device reports the target filtering information, the network device may determine the moving speed of the terminal device faster and with less computational resources.

In another possible implementation, the terminal device may also send an index of the target filtering information to the network device. In this embodiment, the size of the data volume occupied by the index is smaller than the size of the data volume occupied by the filtering information, so that by reporting the index of the target filtering information, channel resources required by reporting can be reduced, reporting speed can be improved, and the like, so that the network device can respond more quickly.

Optionally, the terminal device may determine a location of the target filtering information in the first filtering information set as an index of the target filtering information. Taking the filter parameters as an example, an exemplary set of filter parameters may be as follows:

index of filter parameters reported by terminal device +.>. For example, a terminalAnd if the end device selects k1, the reported index m=0. For another example, if kM is selected by the terminal device, the reported index m=m-1.

In addition, when the network device issues the first filter information set, the network device may issue index identifiers corresponding to the first filter information, where the index identifiers indicate indexes of the first filter information, and the terminal device may determine the index of the target filtering information based on the index identifier corresponding to the first filter information.

The first filter information set issued by the network device may be a complete set of filter information or a subset of the complete set of filter information of the target measurement parameters configured by the network device. That is, the first set of filter information issued by the network device includes all or part of the filter information configured by the network device.

If the first filter information set issued by the network device includes all filter information configured by the network device, the terminal device may select target filter information from the first filter information set according to actual situations, and may reduce the number of times of transmitting the filter information set between the network device and the terminal device, and if the network device issues part of the filter information to the terminal device, the network device may reduce channel resources required for issuing the filter information set each time.

In some example cases, however, if the first filter information issued by the network device is part of all the filter information configured by the network device, it may be difficult for the terminal device to select appropriate filter information for filtering in some cases. The network device may divide the movement speed into a plurality of movement speed intervals, wherein one part of the movement speed intervals issues all the filtering information and another part of the movement speed intervals issues part of the filtering information. For example, when the network device divides the moving speed into a low-speed section, a medium-speed section or a high-speed section, and in general, the terminal device is relatively more located in the low-speed section and the medium-speed section, the first filter information set issued by the network device may include all filter information corresponding to the low-speed section and all filter information corresponding to the medium-speed section, and include part of the filter information of the high-speed section. At this time, if the moving speed of the terminal device enters a high speed section, the filter information selected in the high speed section is relatively limited.

Thus, in one possible implementation, the communication method may further include:

s210, the network equipment sends a second filtering information set to the terminal equipment, wherein the second filtering information set comprises a plurality of second filtering information.

The second filtering information is used for filtering a third measurement result of the target measurement parameter. There is filtering information that is different between the plurality of second filtering information and the plurality of first filtering information. Illustratively, the first plurality of filter parameters includes filter parameters k1 and k2, and the second plurality of filter parameters may include k1 and k3 or k3 and k4, etc., without limitation. The third measurement includes a measurement result obtained after the first measurement result, for example, at a third time, the terminal device measures the target measurement parameter of the at least one cell, to obtain the third measurement result. The third time is later than the first time.

Alternatively, the second set of filtering information may be a complete set or a subset of a complete set, which is not limited herein. If the second set of filtering information is a subset of the full set, it may be that the network device determines the second set of filtering information based on current relevant information of the terminal device, e.g. based on a movement speed of the terminal device. In one possible implementation manner, when the moving speed of the terminal device changes, that is, when the current moving speed of the terminal device is different from or is different from the speed of the terminal device when the first filtering information set is issued (for example, the speed difference is greater than the speed difference threshold value), the second filtering information set may be issued based on the current moving speed of the terminal device, and then the number of filtering information related to the current moving speed in the second filtering information set is greater than the number of filtering information related to the current moving speed in the first filtering information set, for example, when the current moving speed is high, all filtering information including a high-speed section in the second filtering information set. The number of the filtering information irrelevant to the current moving speed in the second filtering information set is smaller than the number of the filtering information irrelevant to the current moving speed in the first filtering information set, for example, the second filtering information set includes partial filtering information of a low-speed section.

It should be understood that, the manner how the terminal device performs filtering based on the second filtering information set may refer to the manner how the terminal device performs filtering based on the first filtering information set, which is not described herein.

It should be noted that, the network device may determine the moving speed of the terminal device based on the target filtering information reported by the terminal device.

In this embodiment, the second filtering information set is issued to the terminal device through the network device, so that the filtering information set configured by the terminal device can be updated in time, and the terminal device can also select more accurate target filtering information for filtering, thereby improving the accuracy of filtering.

Optionally, the plurality of first filtering information and the plurality of second filtering information are the same in number.

In one example, assuming that k1 and k2 correspond to the speed of the low speed interval, k3 and k4 correspond to the speed of the medium speed interval, and k5 and k6 correspond to the speed of the high speed interval, the first set of filter parameters may include: k1, k2, k3, k4 and k5, the second set of filter parameters may comprise k2, k3, k4, k5 and k6.

In another possible implementation manner, the terminal device may predict a change trend of the related information of the terminal device to obtain a change trend prediction result, if the change trend prediction result indicates that the change value of the related information is greater than the change threshold, the change trend prediction result indicates that the filtering information configured by the terminal device needs to be updated, and then the terminal device sends second information to the network device, where the second information indicates to issue a second filtering information set. The network device issues a second set of filtered information upon receiving the second information. When the network device issues the second filtering information set, the network device may issue the full set or the subset in combination with the channel resources thereof, for example, if the channel resources are tense, that is, the available channel resources are less, the subset is issued; and issuing the complete set when the channel resources are loose, i.e. the available channel resources are more.

When the terminal device predicts the change trend of the relevant information, the change trend of the relevant information can be predicted by the change information of the sensor of the terminal device. For example, taking the case that the related information includes a moving speed value, the speed of the terminal device may be acquired by a speed sensor of the terminal device, or the like, and if the speed acquired by the speed sensor gradually decreases and the last acquired speed is lower than the speed threshold, the change trend prediction result may be considered to indicate that the change value of the related information is greater than the change threshold. Or, the acceleration of the terminal device is collected through the acceleration sensor of the terminal device, and if the speed is reduced and the acceleration is relatively large, the change trend prediction result can be considered to indicate that the change value of the related information is larger than the change threshold value.

It will be appreciated that the above manner is a prediction example of how to determine the trend of change of the related information, and other manners may be selected to make the prediction as needed, which is not limited herein.

Alternatively, the second information may include a moving speed of the terminal device or an identifier indicating a moving speed, etc., which is not limited herein.

The above embodiment describes the case of updating the filter information set when the relevant information of the mobile terminal changes, but in another possible implementation manner, when the information of the network device changes, for example, after the filter information configured by the network device is updated, the network device issues the latest filter information set, so that the terminal device can acquire the latest filter information set.

It should be understood that the sequence numbers of the above methods do not mean the order of execution, and the order of execution of the processes should be determined by the functions and internal logic thereof.

It should be appreciated that in some embodiments, steps S208 and S210 may not be required.
