It should be noted that, all actions for acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.

Fig. 1 is a flowchart illustrating a method of determining a target cell, as shown in fig. 1, for use in a User Equipment (UE), according to an exemplary embodiment, comprising the following steps.

In step S101, a plurality of time information, which is the time at which a plurality of candidate cells are to serve a target area, is acquired.

It should be noted that, in the embodiment of the present disclosure, the UE is located in the coverage area of the NTN network, and due to the discontinuous coverage of the NTN network, when the network device moves relative to the UE, the serving cell provided for the UE also moves, and when the range of the serving cell provided by the network device deviates from the range of the area corresponding to the UE, the UE needs to perform cell reselection to ensure the smoothness of the UE communication network. The UE determines a plurality of candidate cells to be selected by acquiring a plurality of time information, which is a time when the plurality of candidate cells are to serve the target area. The time information may be sent to the UE by the network device corresponding to the candidate cell, where the candidate cells correspond to the network devices, and when the network device moves to a range within a certain distance from the UE, the time information that the candidate cell corresponding to the network device will serve the target area is sent to the UE; the plurality of time information may also be transmitted to the UE by a network device of a serving cell of the UE. Alternatively, the network device may determine a plurality of time information that the plurality of network devices are to provide services to the UE according to a time when the serving cell range is out of the UE by determining a distance from other network devices in the area. The network device may be a communication satellite that provides network services in an NTN network.

Optionally, the target area is an area where the user equipment is located, or the time information includes associated location information, where the associated location information is used for determining the target area by the user equipment according to the associated location information.

For example, in the embodiment of the present disclosure, if the time information does not include the associated location information, the corresponding target area is the area where the UE is located, and the UE determines, according to the plurality of time information, a plurality of candidate cells that are to provide services for the target area. If the time information includes the associated location information, the associated location information is used to indicate the location of the area where the time information corresponds to the candidate cell and provides the network service currently, after the UE receives the associated location information, the UE can process the time information and determine the time for providing the service for the UE through the distance between the current location information of the UE and the associated location information and the set moving speed of the network device.

In step S102, a target cell of the user equipment is determined from the plurality of candidate cells according to the plurality of time information.

For example, the UE determines, from the corresponding plurality of candidate cells, a target cell serving the UE through the plurality of time information, wherein, a candidate cell capable of serving a target area earliest (or understood as fastest) among the plurality of candidate cells can be determined as the target cell of the UE through the plurality of time information; the candidate cell serving the UE in the specific time range may be determined as the target cell according to the actual network requirement of the UE and the plurality of time information, which is not limited in this embodiment.

By the method, when the user equipment performs cell reselection, the target cell for providing service for the user equipment is determined from a plurality of candidate cells corresponding to the plurality of time information. Therefore, network unsmooth caused by discontinuous coverage of the network equipment is avoided, and network smoothness of the user equipment is ensured.

Fig. 2 is a flowchart illustrating a method of determining a target cell, as shown in fig. 2, for use in a User Equipment (UE), according to an exemplary embodiment, comprising the following steps.

In step S201, a plurality of time information, which is the time at which a plurality of candidate cells are to serve a target area, is acquired.

For example, in the embodiment of the present disclosure, the manner of acquiring the plurality of time information is consistent with that in the step S101, and reference may be made to the step S101, which is not repeated.

In step S202, a candidate cell serving the target area earliest or fastest is determined from among the plurality of candidate cells as a target cell of the user equipment according to the plurality of time information.

For example, for a non-continuous coverage scenario of a satellite in NTN, in order to ensure continuity of a communication network corresponding to a UE as much as possible, in an embodiment of the present disclosure, a plurality of pieces of time information acquired by the UE are compared with a current time, and a candidate cell that can provide service for a target area corresponding to the UE at earliest or fastest among a plurality of candidate cells corresponding to the plurality of pieces of time information is determined as a target cell of the UE, so as to ensure continuity of network communication of the UE. For example, the time information corresponds to T1:2022, 08, 01, 20:03:55, T2:2022, 08, 01, 20:04:55, T3: and 2022, 08 and 01, 20:03:45, selecting the candidate cell corresponding to the T1 as a target cell of the UE.

By the method, when the user equipment performs cell reselection, the candidate cell which can provide service for the user equipment earliest or fastest is determined from a plurality of candidate cells corresponding to the plurality of time information and is used as a target cell of the user equipment. Therefore, network unsmooth caused by discontinuous coverage of the network equipment is avoided, the user equipment can rapidly accept network services, and network continuity and smoothness of the user equipment are ensured.

Fig. 3 is a flowchart illustrating a method of determining a target cell, as shown in fig. 3, for use in a User Equipment (UE), according to an exemplary embodiment, comprising the following steps.

In step S301, a plurality of time information, which is the time at which a plurality of candidate cells are to serve a target area, is acquired.

In step S302, a target cell of the user equipment is determined from the plurality of candidate cells according to the plurality of time information and the set reselection criteria.

It should be noted that, when the UE performs cell reselection, the UE needs to measure the signal quality of the neighboring cell to determine whether the cell can be used as a candidate cell. The reselection criterion set in the embodiment of the present disclosure is an R criterion, and when the neighbor cell measurement criterion is satisfied, the UE measures the signal quality of the neighbor cell, and determines, according to the measurement result, an R value of each candidate cell according to the R criterion, where the R value is used as the signal quality parameter. Wherein the R value of each candidate cell may be calculated by:

R _s ＝Qmeas,s+Qhyst–Qoffsettemp

R _n ＝Qmeas,n-Qoffset–Qoffsettemp

Wherein R is _s R is the R value of the serving cell, R _n Is R value of neighbor cell, qmeas, s is RSRP (Reference Signal Receiving Power, reference signal received power) measured value of serving cell, qmeas, n is RSRP measured value of neighbor cell, qhyst is cell reselection hysteresis value, qoffset is temporary additional biasAnd shifting the value, wherein Qoffset is the neighbor cell reselection offset value. If Qoffsets are configured in the neighboring cells for the same-frequency cell, the Qoffsets are equal to Qoffsets n when the Qoffsets are configured in the neighboring cells, and the Qoffsets are equal to 0 when the Qoffsets are not configured in the neighboring cells; if Qoffsets are configured in the neighboring cells for the inter-frequency cell, qoffset is equal to Qoffsets, n+Qoffset frequency, if Qoffsets are not configured in the cell, qoffset is equal to Qoffset frequency, wherein Qoffset frequency is the bias value of the neighboring cell strength higher than that of the serving cell.

It should be noted that in the embodiment of the present disclosure, the UE measures a plurality of candidate cells corresponding to a plurality of time information, and determines R values of the candidate cells according to the R criteria. And selecting a target cell of the UE from the plurality of candidate cells according to the plurality of R values corresponding to the plurality of candidate cells. For example, the signal quality may be according to the signal quality requirement of the UE, for example, the signal quality may be represented by an R value, the larger the R value, the better the signal quality. Determining a plurality of target candidate cells meeting the signal quality requirement in a plurality of candidate cells according to a plurality of R values, and selecting a cell which can provide service for the UE earliest or fastest from the plurality of target candidate cells as a target cell of the UE according to a plurality of time information corresponding to the plurality of target candidate cells; and selecting a candidate cell with the largest R value from the plurality of candidate cells as a target cell of the UE according to the plurality of R values.

According to the scheme, the user equipment measures a plurality of candidate cells through a plurality of time information and a set reselection criterion to obtain a plurality of R values, and a target cell of the user equipment is determined from the plurality of candidate cells according to the R values. Therefore, the user equipment can select the cell meeting the cell reselection standard from the plurality of candidate cells as the target cell, the accuracy of cell reselection of the user equipment is improved, the network unclean caused by discontinuous coverage of the network equipment is avoided, and the network unclean of the user equipment is ensured.

Fig. 4 is a flowchart illustrating a method of determining a target cell, as shown in fig. 4, for use in a User Equipment (UE), according to an exemplary embodiment, comprising the following steps.

In step S401, a plurality of time information, which is the time at which a plurality of candidate cells are to serve a target area, is acquired.

In step S402, a plurality of signal quality parameters corresponding to a plurality of candidate cells are determined according to the set reselection criteria.

For example, in the embodiment of the present disclosure, the UE measures the signal of each candidate cell to obtain the signal quality parameter corresponding to each candidate cell, where the signal quality parameter may be the R value in the step S302, and the manner of determining the plurality of signal quality parameters may refer to the step S302 and is not repeated.

In step S403, a first set number of target candidate cells with the best signal parameters are determined among the plurality of candidate cells according to the plurality of signal quality parameters.

For example, after determining a plurality of signal quality parameters (R values) of a plurality of candidate cells through the above steps, a first set number of target candidate cells are extracted from the plurality of candidate cells according to the plurality of R values. The first set number may be set according to a configuration of the UE, or may be set by a serving cell of the UE. And the UE selects a target candidate cell with the first set number and the best signal quality parameter from a plurality of candidate cells corresponding to the plurality of time information according to the first set number. For example, a first set number of target candidate cells may be selected from a plurality of candidate cells satisfying a range of R-value requirements corresponding to the UE according to a communication network requirement of the UE; and the target candidate cells with the first set number and the largest R value in the candidate cells can be taken according to the R values corresponding to the candidate cells.

Optionally, the step S403 may further include:

and sorting the plurality of candidate cells according to the plurality of signal quality parameters to obtain sorting of the plurality of candidate cells, wherein the better the signal quality parameters of the candidate cells are, the higher the ranking in the sorting is.

And selecting the first set number of candidate cells with the highest rank as target candidate cells in the ranking of the plurality of candidate cells.

For example, the signal quality parameter is used to reflect the signal quality of the network signal provided by the corresponding candidate cell, when the signal quality of the network signal corresponding to the candidate cell is weaker, the signal quality parameter is worse, and when the signal quality of the network signal corresponding to the candidate cell is stronger, the signal quality parameter is better. And measuring a plurality of candidate cells corresponding to the plurality of time information by setting a reselection criterion in the steps, and obtaining a plurality of signal quality parameters corresponding to the plurality of candidate cells. And sorting the candidate cells corresponding to the signal quality parameters according to the quality relation of the signal quality parameters, wherein the better the signal quality parameters of the candidate cells are, the higher the ranking of the candidate cells in the sorting is, and the first set number of candidate cells with the highest ranking in the sorting are selected as target candidate cells. It can be understood that, assuming that the number of candidate cells is m, where n is less than or equal to m, and m and n are positive integers, the signal quality measurement can be performed on the m candidate cells to obtain corresponding m signal quality parameters, where the m candidate cells are ranked according to the m signal quality parameters, the better the signal quality parameters are, the higher the ranking of the candidate cells in the ranking is, and the lower the ranking is, and after the ranking of the m candidate cells is obtained, the first n candidate cells in the ranking are selected as target candidate cells. For example, if m=10, n=4, and the signal quality parameter is the R value, the R values of the 10 candidate cells are ordered according to the R values corresponding to the candidate cells, and the ordered candidate cells may be regarded as a cell sequence, and the candidate cells in the first 4 bits in the sequence are extracted as target candidate cells.

In step S404, according to the plurality of time information, the earliest or fastest serving target candidate cell is determined as the target cell of the user equipment among the first set number of target candidate cells.

For example, the time information corresponding to the first set number of target candidate cells is compared, and a cell capable of providing service for the UE earliest or fastest is determined as the target cell of the UE from the target candidate cells. When the UE performs cell reselection, the determined target cell is a candidate cell which can provide service earliest and has better signal quality.

According to the scheme, the first set number of target cells are determined from the candidate cells corresponding to the time information according to the set reselection criteria, and the cell which provides service for the user equipment earliest or fastest is determined as the target cell of the user equipment from the target cells. Therefore, when the user terminal reselects the cell, the cell which can provide service as soon as possible and has better signal quality is selected, the network is prevented from being unsmooth due to discontinuous coverage of the network equipment, the network smoothness of the user equipment is ensured, and the user has better product experience.

Fig. 5 is a flowchart illustrating a method of determining a target cell, as shown in fig. 5, for use in a User Equipment (UE), according to an exemplary embodiment, comprising the following steps.

In step S501, a plurality of time information, which is the time at which a plurality of candidate cells are to serve a target area, is acquired.

In step S502, a second set number of target candidate cells that serve the target area earliest or fastest among the plurality of candidate cells is determined according to the plurality of time information.

For example, in the embodiment of the present disclosure, the configuration manner of the second set number is the same as that in the step S403, and reference may be made to the step S403, which is not repeated. The second set number of values may be fixed values, or may be matched according to the configuration of the UE. The time information corresponding to each candidate cell is the time for the candidate cell to provide service for the target area, and the second set number of target candidate cells which provide service for the target area earliest or fastest can be selected from the plurality of candidate cells corresponding to the plurality of time signals by comparing the plurality of time information.

Optionally, the step S502 may further include:

and sorting the plurality of candidate cells according to the plurality of time information to obtain sorting of the plurality of candidate cells, wherein the earlier the time indicated by the time information of the candidate cells is, the higher the ranking in the sorting is, and otherwise, the lower the ranking in the sorting is.

And selecting a second set number of candidate cells with highest ranking from the ranking of the plurality of candidate cells as target candidate cells. It may be understood that, assuming that the candidate cells have m number of second set number of n, the m candidate cells may be ranked according to m pieces of time information corresponding to the m candidate cells, and since the earlier the time indicated by the time information of the candidate cells is, the higher the rank in the ranking is, after the ranking of the m candidate cells is obtained, the first n candidate cells in the ranking are selected as target candidate cells.

For example, in an embodiment of the present disclosure, the time information may be a future time point at which the candidate cell may serve the UE at the fastest, and the corresponding plurality of candidate cells are ordered according to the plurality of time information, where the earlier the future time point indicated by the time information corresponding to the candidate cell, the higher the ranking in the sequence. And selecting the second set number of candidate cells with highest ranking from the ranking of the candidate cells as target candidate cells. For example, the second set number is set to 5, and the plurality of time information corresponding to the plurality of candidate cells is respectively: t1:2022, 08, 01, 10:13:50, T2:2022, 08, 01, 10:12:55, T3:2022, 08, 01, 10:10:55, T4:2022, 08, 01, 10:22:55, T5:2022, 08, 01, 10:26:53, T6:2022, 08, 01, 10:19:54, T7:2022, 08, 01, 10:25:01, and ordering the plurality of candidate cells according to the sequence of future time points to obtain: and 5 candidate cells are extracted from the sequence by T3-T2-T1-T6-T4-T5-T7, and target candidate cells corresponding to the 5 candidate cells by T3-T2-T1-T6-T4 are obtained.

In step S503, signal quality parameters of a second set number of target candidate cells are determined according to the set reselection criteria.

For example, in the embodiment of the present disclosure, the manner of determining the signal quality parameter is the same as that in the step S402, and reference may be made to the step S402, which is not repeated.

In step S504, the target candidate cell with the best signal quality parameter is determined as the target cell of the user equipment from the second set number of target candidate cells.

For example, according to the signal quality parameters determined in the above steps, a cell with the best signal quality parameter among the second set number of target candidate cells is selected as the target cell of the UE. When the UE reselects the cell, the cell with better signal quality and faster service for the UE can be selected as the target cell.

By the scheme, the target cells with the second set number are determined from the candidate cells corresponding to the time information, and then the cell with the best signal quality is determined from the target cells to be the target cell of the user equipment. Therefore, when the user terminal reselects the cell, the cell which can provide service as soon as possible and has better signal quality is selected, the network is prevented from being unsmooth due to discontinuous coverage of the network equipment, the network smoothness of the user equipment is ensured, and the user has better product experience.

Fig. 6 is a flowchart illustrating a method of determining a target cell, as shown in fig. 6, for use in a User Equipment (UE), according to an exemplary embodiment, comprising the following steps.

In step S601, a plurality of time information, which is the time at which a plurality of candidate cells are to serve a target area, is acquired.

In step S602, a time threshold is acquired, where the time threshold includes time information or duration information.

For example, the configuration manner of the time threshold in the embodiment of the present disclosure may be the same as that in step S403, and will not be described in detail with reference to step S403. The time threshold may be time information of a future time, for example, the current time is 2022, 08, 01, 10:00:00, and the time threshold may be 2022, 08, 01, 10:10:00; the time threshold may also be duration information, e.g., 10 minutes, 5 minutes, etc.

In step S603, a candidate cell satisfying the time threshold is determined from among the plurality of candidate cells as a target cell of the user equipment according to the plurality of time information.

For example, comparing the plurality of time information obtained in the step with a time threshold, and determining a cell meeting the time threshold from a plurality of candidate cells corresponding to the plurality of time information as a target cell of the UE. It should be noted that, the plurality of candidate cells are screened through a time threshold, the obtained cell can be one or a plurality of cells, and when the obtained cell is determined to be unique, the cell is taken as a target cell of the UE; when the obtained cells are determined to be multiple, one of the cells selected from the multiple cells can be selected randomly as the target cell of the UE, or the cell which can provide service for the UE the fastest can be selected from the multiple cells as the target cell of the UE, which is not limited in this embodiment.

Optionally, in an embodiment, the time threshold is time information, and the step S603 may include:

and comparing the time information with the time information respectively.

And determining the candidate cell corresponding to any time information as the candidate cell meeting the time threshold under the condition that any time information is before the time information or the condition that any time information is the same as the time information.

For example, in the embodiment of the present disclosure, the time threshold is time information, a plurality of time information is compared with the time threshold, and when the time information is before the time threshold or when the time information is equal to the time threshold, it is determined that the corresponding candidate cell meets the time threshold; when the time information is after the time threshold, it is determined that the corresponding candidate cell does not satisfy the time threshold.

Optionally, in another embodiment, the time threshold is duration information, and step S603 may further include:

and determining a plurality of target durations corresponding to the plurality of candidate cells according to the plurality of time information and the current time information.

And respectively comparing the plurality of target time lengths with the time length information.

And under the condition that any target duration is less than or equal to the duration information, determining the candidate cell corresponding to any target duration as the candidate cell meeting the time threshold.

In an example, in the implementation of the present disclosure, the time information is duration information, and the time information corresponding to each candidate cell and the current time information are calculated to determine a target duration corresponding to each candidate cell. Comparing each target time length with time length information, and determining that a candidate cell corresponding to the target time length meets a time threshold when the target time length is smaller than or equal to the time length information; and when the target time length is longer than the time length information, determining that the candidate cell corresponding to the target time length does not meet the time threshold. By way of example, the plurality of time information are respectively: t1:2022, 08, 01, 10:13:55, T2:2022, 08, 01, 10:24:55, T3:2022, 08, 01, 10:33:45, T4:2022, 08, 01, 10:03:13, T5:2022, 08, 01, 10:14:21, T6:2022, 08, 01, 10:11:45; and when the current time information is 2022, 08, 01, 10:00:00 and the set time length information is 15 minutes, determining candidate cells meeting the time length information in T1-T6 as candidate cells corresponding to T1, T4, T5 and T6.

Through the scheme, the candidate cells corresponding to the time information are screened through the time threshold, and the cell meeting the time threshold is determined to be a target cell of the user equipment. Therefore, network unsmooth caused by discontinuous coverage of the network equipment is avoided, and network smoothness of the user equipment is ensured.

Fig. 7 is a flowchart illustrating a method of determining a target cell, as shown in fig. 7, for use in a User Equipment (UE), according to an exemplary embodiment, comprising the following steps.

In step S701, a plurality of time information, which is the time at which a plurality of candidate cells are to serve a target area, is acquired.
