[0086] In order to facilitate a clearer understanding of the various embodiments of the present application, some relevant background technical knowledge is first introduced as follows.

[0087] 1. UAV

[0088] Unmanned aerial vehicles, commonly known as drones, unmanned combat aircraft or bee-shaped aircraft, are broadly defined as various remote-controlled aircraft that do not require a pilot to operate. They are usually divided into military and civilian uses.

[0089] 2. No-Transmit Zone (NTZ)

[0090] The Conference of European Post and Telecommunications Administrations (CEPT) has made Decision 22(07) on the harmonization of technical conditions for airborne UEs based on Long Term Evolution (LTE) and 5G New Radio (NR) in multiple frequency bands. This decision assumes a variety of technical conditions and requirements for supporting airborne UEs in mobile systems (LTE and NR), among which the issues worth noting are the No Transmission Zone (NTZ) and Out-Of-Band Emission (OOBE).

[0091] A no-go zone is defined as a geographical area where UAVs are not allowed to transmit in a given Multi Frequency Communication Networks (MFCN) band or a portion thereof for spectrum compatibility purposes.

[0092] 3. Cell access prohibition mechanism

[0093] During the initial access phase, after the UE obtains time and frequency synchronization, it will read the Master Information Block (MIB), which contains the cell barred parameter. The parameter value is used to indicate whether the current cell allows idle / inactive UEs to reside. If the parameter value is set to "barred", it means that the UE is not allowed to reside in the current cell. If the parameter value is set to "not barred", it means that the UE is allowed to reside in the current cell.

[0094] 4. Unified Access Control (UAC) Mechanism

[0095] Access control is a control technology that restricts the terminal from accessing the network. It is convenient for classifying and controlling the terminal to initiate different types of access requests. By applying access control technology, the network can well manage the resource usage of the entire network. The following is the basic process of the UAC mechanism:

[0096] Step 1: The terminal determines the access category:

[0097] If T390 is running (T390: T390 will be started for a certain access category that is prohibited from access. During the timer running, access categories of the same category are not allowed to access), the access category is considered to be prohibited;

[0098] If T302 is running (T302: the terminal receives a Radio Resource Control (RRC) Reject, or receives an RRC Release (Release) message containing a wait time), and the access category is neither 0 nor 2 at this time, the access category is considered to be prohibited;

[0099] For access category 0, it is considered that this category allows access;

[0100] For the remaining access categories, if the System Information Block (SIB) 1 contains a UAC-BarringForCommon parameter or a UAC-ACBarringListType, if the above parameters contain a corresponding UAC access barring set (UAC-BarringInfoSet) for a specific access category, an access barring check is performed on the corresponding access category; otherwise, the access category is considered to be allowed.

[0101] Step 2: Access barring check:

[0102] The terminal determines the access identifier:

[0103] If the terminal is indicated with one or more access identifiers, where the access identifier is equal to 1, 2, 11, 12, 13, 14 or 15, and the bit corresponding to the UAC access identifier barring (uac-BarringForAccessIdentity) parameter corresponding to at least one of the access identifiers is set to 0, then the access is considered to be allowed;

[0104] For a terminal with access ID 3, a random number between 0 and 1 is generated. If the random number is less than the probability indicated by the barring factor (BarringFactorForAI3) of UAC access ID 3, the access is considered to be allowed.

[0105] Otherwise, the terminal generates a random number between 0 and 1. If the random number is less than the UAC Barring Factor, the access is considered to be allowed.

[0106] If the access is considered to be prohibited, the terminal generates a random number rand between 0 and 1, and the terminal starts T390, wherein the duration of T390 is calculated according to T390=(0.7+0.6*rand)*uac-BarringTime.

[0107] 5. Priority rules for cell reselection

[0108] The priority rules for cell reselection involve: high priority frequency (NR or different system), different frequencies with the same frequency and the same priority, and low priority (NR or different system). When the communication service quality of the serving cell is poor and the UE has enabled multiple measurement states, if the terminal finds multiple suitable neighboring cells that meet the reselection conditions (the reselection conditions comprehensively consider the priority between frequencies, the quality of the serving cell, the quality of the neighboring cells, and the ping-pong effect), it selects the neighboring cell with the highest priority to access and reside in according to the priority from top to bottom.

[0109] The terminal control method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0110] The terminal control method provided in the embodiment of the present application can be applied to a scenario where it is necessary to restrict the behavior of the terminal in a forbidden transmission zone. The terminal receives first configuration information related to the NTZ sent by a network side device, and the terminal performs a first operation based on the first configuration information. The first operation includes at least one of the following: prohibiting staying in the first cell; prohibiting measuring the first frequency point when selecting or reselecting a cell; prohibiting selecting the first cell when selecting or reselecting a cell; starting to measure the first cell; prohibiting initiating access in the first cell; wherein the first frequency point is a frequency point covered by the restricted frequency band of the NTZ; the first cell is a cell whose frequency band is completely covered by the restricted frequency band of the NTZ or works at a frequency point covered by the restricted frequency band of the NTZ. Since the first configuration information is related to the NTZ, the network side device can send the first configuration information to the terminal to ensure that the terminal is not allowed or the terminal is not allowed to stay in the first cell or initiate uplink access, perform uplink transmission, or select the first cell during cell selection / reselection. Or the probability of such behavior or probability is reduced, thereby restricting the behavior of the terminal in the forbidden transmission zone and avoiding interference with adjacent cells.

[0111] Figure 2 is one of the flow charts of the terminal control method provided in the embodiment of the present application, such as Figure 2 As shown, the method includes steps 201 and 202; wherein:

[0112] Step 201: The terminal receives first configuration information sent by a network-side device; the first configuration information is related to a no-transmission zone NTZ.

[0113] It should be noted that the embodiments of the present application can be applied to scenarios where it is necessary to restrict the behavior of the terminal in the prohibited transmission zone. The terminal includes but is not limited to the types of terminals 11 listed above. The terminal can be an aerial terminal based on LTE and 5G NR, such as UAV UE, drone, unmanned combat aircraft or bee-type aircraft. The network side equipment includes but is not limited to the types of network side equipment 12 listed above, and the embodiments of the present application are not limited to this.

[0114] Specifically, the network side device may send first configuration information to the terminal, where the first configuration information is related to the NTZ, and the terminal receives the first configuration information sent by the network side device.

[0115] Step 202. The terminal performs a first operation based on the first configuration information; the first operation includes at least one of the following: prohibiting staying in the first cell; prohibiting measuring the first frequency point when selecting or reselecting a cell; prohibiting selecting the first cell when selecting or reselecting a cell; starting measuring the first cell; prohibiting initiating access in the first cell; wherein the first frequency point is a frequency point covered by the restricted frequency band of the NTZ; the first cell is a cell whose frequency band is completely covered by the restricted frequency band of the NTZ or operates at a frequency point covered by the restricted frequency band of the NTZ.

[0116] Specifically, after receiving the first configuration information sent by the network side device, the terminal can perform a first operation according to the first configuration information; wherein the first operation includes at least one of the following: prohibiting staying in the first cell; prohibiting measuring the first frequency point when selecting or reselecting the cell; prohibiting selecting the first cell when selecting or reselecting the cell; starting measurement of the first cell; prohibiting initiating access in the first cell; wherein the first frequency point is a frequency point covered by the restricted frequency band of NTZ, that is, at the first frequency point, the terminal is prohibited from performing frequency point measurement; the first cell is a cell whose frequency band is completely covered by the restricted frequency band of NTZ or works at a frequency point covered by the restricted frequency band of NTZ, that is, in the first cell, the terminal is prohibited from staying, or when selecting or reselecting the cell, it is prohibited to select, start measurement or initiate access, so as to restrict the behavior of the terminal in the prohibited transmission area.

[0117] In the terminal control method provided in the embodiment of the present application, the terminal receives the first configuration information related to the NTZ sent by the network side device, and the terminal performs a first operation based on the first configuration information, and the first operation includes at least one of the following: prohibiting staying in the first cell; prohibiting measuring the first frequency point when selecting or reselecting the cell; prohibiting selecting the first cell when selecting or reselecting the cell; starting to measure the first cell; prohibiting initiating access in the first cell; wherein the first frequency point is a frequency point covered by the restricted frequency band of the NTZ; the first cell is a cell whose frequency band is completely covered by the restricted frequency band of the NTZ or works at a frequency point covered by the restricted frequency band of the NTZ. Since the first configuration information is related to the NTZ, the network side device can send the first configuration information to the terminal to ensure that the terminal is not allowed or the terminal is not allowed to stay in the first cell or initiate uplink access, perform uplink transmission, or select the first cell during cell selection / reselection, etc., or the probability of the terminal being selected is reduced, thereby restricting the behavior of the terminal in the prohibited transmission area and avoiding interference with adjacent cells.

[0118] Optionally, the first configuration information includes at least one of the following:

[0119] (1) A cell access prohibition parameter, used to indicate whether the terminal is prohibited from staying in the first cell.

[0120] For example, the cell barred access parameter may be cellBarredUAV. When the value of cellBarredUAV is set to barred, it indicates that the UAV UE is not allowed to reside in the first cell. When the value of cellBarredUAV is set to not barred, the UAV UE is allowed to reside in the first cell.

[0121] (2) a cell prohibited transmission list, including the first cell, and the cell in the cell prohibited transmission list can only be the first cell.

[0122] Specifically, the first cell is a cell whose frequency band is completely covered by the restricted frequency band of NTZ or operates at a frequency point covered by the restricted frequency band of NTZ. The cells in the cell prohibition list can only be cells whose frequency band is completely covered by the restricted frequency band of NTZ or operate at a frequency point covered by the restricted frequency band of NTZ.

[0123] (3) A list of cells allowed to transmit, including cells that are not covered by the restricted frequency band of the NTZ or cells operating at frequencies that are not covered by the restricted frequency band of the NTZ, and the cells in the list of cells allowed to transmit can only be cells that are not covered by the restricted frequency band of the NTZ or cells operating at frequencies that are not covered by the restricted frequency band of the NTZ.

[0124] Specifically, the cells in the cell allowed transmission list can only be cells that are not covered by the restricted frequency band of the NTZ or cells that operate at frequencies that are not covered by the restricted frequency band of the NTZ.

[0125] (4) A first frequency point list, including the first frequency point, and the frequency point in the first frequency point list can only be the first frequency point.

[0126] Specifically, the frequencies in the first frequency list can only be frequencies covered by the restricted frequency band of the NTZ.

[0127] (5) A first high priority frequency list includes frequencies used to start high priority frequency measurement. The first high priority frequency list does not include the first frequency.

[0128] Specifically, the frequencies included in the first high priority frequency list are frequencies used when the NAV UE starts high priority frequency measurement. The first high priority frequency list does not include the first frequency, that is, does not include the NTZ frequency.

[0129] (6) A first low-priority frequency point list includes frequencies used to start low-priority frequency point measurement, and the first low-priority frequency point list does not include the first frequency point.

[0130] Specifically, the frequencies included in the first low priority frequency list are frequencies used when the NAV UE starts low priority frequency measurement. The first low priority frequency list does not include the first frequency, that is, does not include the NTZ frequency.

[0131] (7) A first frequency list of equal priority includes frequencies used to start measurement of equal-priority different-frequency frequencies, wherein the first frequency list of equal priority does not include the first frequency.

[0132] Specifically, the frequencies included in the first equal priority frequency list are the frequencies used when the NAV UE initiates equal priority inter-frequency frequency measurement. The first equal priority frequency list does not include the first frequency, that is, does not include the NTZ frequency.

[0133] (8) A first measurement start threshold, used to indicate a threshold for starting the measurement of the first cell.

[0134] Specifically, the first measurement start threshold is used to indicate the threshold for starting the first cell measurement, that is, the threshold for starting the measurement of the NTZ covered cell. For example, the network side device can configure a relatively small first measurement start threshold to ensure that the terminal can select the NTZ restricted cell only when the signal quality of the serving cell is too poor and may not be able to stay normally.

[0135] (9) First start threshold offset.

[0136] Specifically, when the first configuration information includes the first start threshold offset, the terminal subtracts the first start threshold offset from the same-frequency and / or different-frequency measurement start threshold to obtain an updated same-frequency and / or different-frequency measurement start threshold, and starts measurement according to the updated same-frequency and / or different-frequency measurement start threshold.

[0137] (10) A first offset list, comprising at least one offset corresponding to at least one cell in the cell ban list, wherein the offsets in the first offset list are in one-to-one correspondence with the cells in the cell ban list, and the offsets in the first offset list are offsets between the corresponding cell and the current resident cell of the terminal.

[0138] Specifically, the offset included in the first bias list is the offset between the corresponding cell in the cell ban list and the current resident cell of the terminal. The offset in the first bias list is in a one-to-one correspondence with the cell in the cell ban list. For example, the offset 1 in the first bias list corresponds to the cell 1 in the cell ban list.

[0139] (11) A first offset, used to represent an offset between each cell in the cell prohibition list and the current resident cell of the terminal.

[0140] Specifically, the first offset is used to represent the offset between each cell in the cell prohibition list and the current resident cell of the terminal, that is, the first offset corresponds to multiple cells in the cell prohibition list, which is a one-to-many correspondence relationship.

[0141] (12) A first minimum reception quality or level, used to determine a cell selection criterion when selecting a cell.

[0142] Specifically, the cell selection criterion is the S criterion. When the first configuration information includes the first minimum reception quality or level, the terminal calculates the S criterion according to the first minimum reception quality or level when selecting a cell.

[0143] (13) The unified access control mechanism UAC access identifier bar parameter is used to indicate whether access corresponding to the access identifier of the terminal is allowed.

[0144] For example, the UAC access identifier bar parameter may be UAC-BarringForAccessIdentity. In the existing mechanism, the parameter is set to 7 bits, and the 7 bits correspond to access identifiers 1, 2, and 11 to 15, respectively. When a new access identifier is introduced for UAVUE, the UAC access identifier bar parameter may be set to 8 bits (bits), with an additional 1 bit corresponding to the UAV UE, or may be indicated by an additional 1 bit. In the above bit representation, 0 indicates that the terminal is allowed to access with the corresponding access identifier.

[0145] (14) A first UAC barring factor, which is used to represent the access probability of the terminal when performing an access barring check.

[0146] For example, the first UAC barring factor may be UAC-BarringFactorUAV. When the UAV UE performs an accessbarring check, the UAV UE generates a random number between 0 and 1. When the random number is smaller than the first UAC barring factor, the UAV UE considers that the access is allowed.

[0147] (15) First absolute threshold.

[0148] For example, when the signal quality of the NTZ restricted cell is greater than the first absolute threshold, only the non-NTZ restricted cells are sorted according to the R criterion, and the UAV UE selects the strongest cell based on the sorting result.

[0149] Optionally, the first configuration information is carried in at least one of the following ways:

[0150] (a) System information;

[0151] (b) dedicated signaling;

[0152] (c)NAS message.

[0153] Optionally, a specific implementation of step 202 may include at least one of the following:

[0154] 1) When the first configuration information includes the cell barred access parameter, the terminal ignores the cellBarred parameter in the MIB message, and when the cell barred access parameter indicates that the terminal is prohibited from staying in the first cell, the terminal does not stay in the first cell.

[0155] Specifically, after the terminal receives the first configuration information, if the first configuration information includes a cell barred access parameter, the terminal can ignore the cellBarred parameter in the MIB message. When the cell barred access parameter indicates that the terminal is prohibited from residing in the first cell, the terminal does not reside in the first cell, that is, the terminal is not allowed to reside in the first cell.

[0156] For example, the cell barred access parameter is cellBarredUAV. When cellBarredUAV is set to barred, the UAV UE is prohibited from staying in the first cell that sends the cellBarredUAV parameter.

[0157] 2) When the first configuration information includes the cell barred access parameter, the terminal ignores the cellBarred parameter in the MIB message, and when the cell barred access parameter indicates that the terminal is not prohibited from staying in the first cell, the terminal is allowed to stay in the first cell.

[0158] Specifically, after the terminal receives the first configuration information, if the first configuration information includes a cell prohibited access parameter, the terminal can ignore the cellBarred parameter in the MIB message. When the cell prohibited access parameter indicates that the terminal is not prohibited from residing in the first cell, the terminal can be allowed to reside in the first cell, that is, the terminal is allowed to reside in the first cell. At this time, the terminal can reside in the first cell.

[0159] For example, the cell barring access parameter is cellBarredUAV. When cellBarredUAV is set to not barred, the UAV UE is allowed to reside in the first cell that sends the cellBarredUAV parameter.

[0160] 3) When the first configuration information includes the cell access prohibition parameter, the terminal does not ignore the cellBarred parameter in the MIB message, and when the cellBarred parameter in the MIB message and any one of the cell access prohibition parameters indicate that the terminal is prohibited from residing in the first cell, the terminal does not reside in the first cell; or, when the cellBarred parameter in the MIB message and the cell access prohibition parameter both indicate that the terminal is not prohibited from residing in the first cell, the terminal is allowed to reside in the first cell.

[0161] Specifically, after the terminal receives the first configuration information, when the first configuration information includes a cell access prohibition parameter, the terminal does not ignore the cellBarred parameter in the MIB message. When any one of the cellBarred parameter and the cell access prohibition parameter in the MIB message indicates that the terminal is prohibited from residing in the first cell, the terminal may not reside in the first cell, that is, the terminal is considered to be prohibited from residing in the cell that sends the cell access prohibition parameter; or, when both the cellBarred parameter and the cell access prohibition parameter in the MIB message indicate that the terminal is not prohibited from residing in the first cell, the terminal may be allowed to reside in the first cell, that is, the terminal is considered to be allowed to reside in the cell that sends the cell access prohibition parameter. The prohibition of the terminal from residing in the first cell is achieved, thereby limiting the opportunity for the terminal to initiate an uplink in the first cell.

[0162] For example, the UAV UE receives the first configuration information through the system message of cell 1, receives cellBarred through the MIB, the cell access prohibition parameter is cellBarredUAV, the UAV UE does not ignore the cellBarred parameter in the MIB message, and when the cellBarred parameter in the MIB message is set to barred and the value of cellBarredUAV is set to barred, the UAV UE is not allowed to reside in cell 1; or, when the cellBarred parameter in the MIB message is set to barred and the value of cellBarredUAV is set to not barred, the UAV UE is not allowed to reside in cell 1; or, when the cellBarred parameter in the MIB message is set to not barred and the value of cellBarredUAV is set to barred, the UAV UE is not allowed to reside in cell 1; or, when the cellBarred parameter in the MIB message is set to not barred and the value of cellBarredUAV is set to not barred, the UAV UE is allowed to reside in cell 1, thereby limiting the UAV UE from residing in the NTZ restricted cell, thereby limiting the opportunity for the UAV UE to initiate uplink in the NTZ restricted cell.

[0163] 4) In the case where the first configuration information includes the cell banned list, the terminal performs one of the following operations: excluding access initiated from cells in the cell banned list; excluding cells in the cell banned list in the sorting of cells that meet the judgment of high priority frequency, co-frequency or low priority frequency (i.e., sorting the cells based on cell reselection criteria according to frequency priority); or, in the sorting of cells that meet the judgment of high priority frequency, co-frequency or low priority frequency, arranging the cells in the cell banned list behind the remaining cells according to the cell reselection criteria.

[0164] Specifically, after the terminal receives the first configuration information, if the first configuration information includes a cell banned list, the terminal can perform one of the following operations: exclude access from cells in the cell banned list. Since the cells in the cell banned list are cells that do not allow the terminal to reside, when the terminal selects or reselects a cell, it does not select the cell in the cell banned list, or selects the cell in the cell banned list, but the terminal will not initiate uplink access in the cell; in the sorting of cells that meet the judgment of high priority frequency, same frequency or low priority frequency, the terminal can exclude the cells in the cell banned list; in the sorting of cells that meet the judgment of high priority frequency, same frequency or low priority frequency (that is, sorting the cells based on the cell reselection criteria according to the frequency priority), the terminal can arrange the cells in the cell banned list after the remaining cells according to the cell reselection criteria (R criteria).

[0165] 5) In the case where the first configuration information includes the cell allowed to transmit list, the terminal is allowed to select a cell in the cell allowed to transmit list when selecting or reselecting a cell.

[0166] Specifically, after the terminal receives the first configuration information, if the first configuration information includes a cell allowed to transmit list, the cells in the cell allowed to transmit list are cells that allow the terminal to reside and initiate uplink access. When selecting or reselecting a cell, the terminal can select a cell in the cell allowed to transmit list.

[0167] 6) When the first configuration information includes at least one of the first high-priority frequency list, the first low-priority frequency list and the first equal-priority frequency list, the terminal starts high-priority frequency measurement for the frequency information in the first high-priority frequency list, or starts low-priority frequency measurement for the frequency information in the first low-priority frequency list, or starts equal-priority frequency measurement for the frequency information in the first equal-priority frequency list when selecting or reselecting a cell.

[0168] Specifically, after the terminal receives the first configuration information, if the first configuration information includes at least one of a first high priority frequency list, a first low priority frequency list and a first equal priority frequency list, the terminal can start high priority frequency measurement for the frequency information in the first high priority frequency list when selecting or reselecting a cell, or start low priority frequency measurement for the frequency information in the first low priority frequency list, or start equal priority frequency measurement for the frequency information in the first equal priority frequency list.

[0169] 7) In a case where the first configuration information includes the first minimum reception quality or level, the terminal determines a cell selection criterion based on the first minimum reception quality or level when selecting a cell.

[0170] Specifically, after the terminal receives the first configuration information, when the first configuration information includes the first minimum reception quality or level, the terminal can calculate the cell selection criterion (ie, S criterion) based on the first minimum reception quality or level when selecting a cell.

[0171] 8) When the first configuration information includes the first measurement start threshold, when the quality of the serving cell is less than the first measurement start threshold, the terminal starts measuring the first cell.

[0172] Specifically, after the terminal receives the first configuration information, in a case where the first configuration information includes a first measurement start threshold, when the quality of the serving cell is less than the first measurement start threshold, the terminal may start measuring the first cell.

[0173] For example, the UAV UE receives first configuration information through system information, and the first configuration information includes a first measurement start threshold. The quality of the service cell of the UAV UE is lower than the same-frequency reselection measurement start threshold, the same priority or low priority reselection measurement start threshold in the existing mechanism, and the UAV UE starts non-NTZ restricted cell measurement; when the quality of the service cell further deteriorates and the quality of the service cell is lower than the first measurement start threshold, the UAV UE starts NTZ restricted cell measurement (i.e., the cell in the cell banned list).

[0174] Optionally, the terminal may also start the measurement of the NTZ restricted cell by subtracting the first measurement start offset from the measurement start threshold.

[0175] In the embodiment of the present application, the network side device may configure a relatively low first measurement start threshold to ensure that the terminal may select the NTZ restricted cell only when the quality of the serving cell is too poor and the terminal may not be able to stay normally.

[0176] 9) When the first configuration information includes the first start threshold offset, the terminal subtracts the first start threshold offset from the same-frequency and / or different-frequency measurement start threshold to obtain an updated same-frequency and / or different-frequency measurement start threshold, and starts measurement according to the updated same-frequency and / or different-frequency measurement start threshold.

[0177] 10) When the first configuration information includes the cell prohibition list and also includes the first offset list or the first offset, the terminal sorts the cells in the cell prohibition list based on a cell reselection criterion according to the first offset list or the first offset.

[0178] Specifically, after the terminal receives the first configuration information, if the first configuration information includes a cell ban list and also includes a first bias list or a first bias, the terminal can sort the cells in the cell ban list according to the first bias list or the first bias, that is, the terminal determines the cell reselection criterion (R criterion) according to the cell ban list and the first bias list, or the cell ban list and the first bias. By avoiding the terminal from selecting an NTZ cell or reducing the probability of selecting an NTZ cell during the cell reselection process, the terminal can avoid the opportunity to initiate an uplink in an NTZ restricted cell.

[0179] For example, the UAV UE receives the first configuration information, the same-frequency neighboring cell list, and the different-frequency carrier frequency list through system information. The first configuration information includes a cell ban list and a first offset list. The UAV UE starts measuring the high-priority frequency in the different-frequency carrier frequency list. When the signal quality of a cell in a high-priority frequency is greater than the absolute threshold of the high-priority signal quality, and the cell does not belong to the cell ban list, the UAV UE reselects to the cell in the high-priority frequency. When the signal quality of the UAV UE serving cell is lower than the same-frequency reselection measurement start threshold, the same priority or low-priority reselection measurement start threshold, the UAV UE starts the same-frequency, different-frequency, same priority or low-priority frequency measurement. The UAV UE sorts by the R criterion to exclude the cells in the cell ban list; or, the UAV UE sorts by the R criterion through the cell ban list and the corresponding first offset list or first offset, wherein the cells in the cell ban list and the offsets in the first offset list are in a one-to-one correspondence. For example, cell 1 in the cell ban list corresponds to offset 1 in the first offset list; for another example, if the first offset is configured, the first offset can be used for all cells in the cell ban list. In order to prevent the UAV UE from reselecting to a cell in the cell ban list, the network side device will allocate a large offset 1 to the UAV UE, calculate the R criterion through the offset 1, and the UAV UE performs cell reselection.

[0180] 11) In a case where the first configuration information includes the first frequency point list, the terminal excludes the frequencies in the first frequency point list when starting to measure the frequencies.

[0181] Specifically, after the terminal receives the first configuration information, if the first configuration information includes a first frequency list, the terminal can exclude the frequencies in the first frequency list when starting to measure the frequencies, thereby reducing the probability of selecting the NTZ cell, thereby limiting the terminal's chance of initiating uplink in the NTZ restricted cell.

[0182] For example, the UAV UE receives first configuration information and a hetero-frequency carrier frequency list through system information, wherein the first configuration information includes a first frequency point list. When the UAV UE measures a high-priority frequency point in the hetero-frequency carrier frequency list, it does not measure the frequency points in the high-priority frequency point list that are included in the first frequency point list.

[0183] Optionally, when the first configuration information includes a first high priority frequency list, the terminal performs high priority frequency measurement on the frequencies in the first high priority frequency list.

[0184] 12) When the first configuration information includes the first absolute threshold and the cell ban list, when the signal quality of the cells in the cell ban list is greater than the first absolute threshold, the terminal only sorts the cells excluding the cell ban list based on the cell reselection criteria.

[0185] Specifically, after the terminal receives the first configuration information, when the first configuration information includes a first absolute threshold and a cell banned list, when the signal quality of a cell in the cell banned list is greater than the first absolute threshold, the terminal only sorts the cells in the excluded cell banned list based on the cell reselection criterion (i.e., the R criterion), and the terminal can select the strongest cell based on the sorting result.

[0186] Optionally, the first configuration information may not be effective under certain conditions. For example, if the UAV UE cannot find any suitable serving cell through the methods described in the above embodiments 1 to 4, the UAV UE may ignore the barred of cellBarredUAV in the system message or the cell banned list, etc.; for another example, for the UAV UE, when cellBarredUAV is set to barred, or any one of the parameter values ​​of cellBarred and cellBarredUAV in the MIB message is set to barred, or for the cells in the cell banned list, the UE may consider the cells in the cell banned list to be acceptable cells.

[0187] 13) When the first configuration information includes the cell banned list and also includes the first frequency list, the NAS layer of the terminal notifies the AS layer of the terminal of the cell banned list and the first frequency list, and after the terminal enters idle / inactive, the terminal selects or reselects a cell based on the cell banned list and the first frequency list.

[0188] Specifically, after the terminal receives the first configuration information, if the first configuration information includes a cell banned list and a first frequency list, the NAS layer of the terminal first notifies the AS layer of the terminal of the cell banned list and the first frequency list. After the terminal enters idle / inactive, the terminal selects or reselects a cell according to the cell banned list and the first frequency list.

[0189] By preventing the terminal from selecting the first cell or reducing the probability of the terminal selecting the first cell during the cell selection or reselection process, the opportunity of the terminal initiating an uplink in the first cell is limited.

[0190] 14) When the UAC access identifier bar parameter is included in the first configuration information, when the UAC access identifier bar parameter indicates that access corresponding to the access identifier of the terminal is allowed, the terminal initiates access; or, when the UAC access identifier bar parameter indicates that access corresponding to the access identifier of the terminal is not allowed, the terminal cancels the access.

[0191] Specifically, after the terminal receives the first configuration information, if the first configuration information includes a UAC access identifier bar parameter, when the UAC access identifier bar parameter indicates that access corresponding to the access identifier of the terminal is allowed, the terminal can initiate access; or, when the UAC access identifier bar parameter indicates that access corresponding to the access identifier of the terminal is not allowed, the terminal can cancel the access.

[0192] For example, the RRC layer of the UAV UE receives a specific access identifier configured for the UAV UE indicated by the high layer, and the UAV UE receives the UAC access identifier bar parameter through the system information. The UAC access identifier bar parameter includes 8 bits, and the value of the UAC access identifier corresponding to the rightmost bit or the highest bit is set to 1, then the UAV UE determines that this access is prohibited. Through the UAC mechanism, the terminal resides in the NTZ restricted cell, but the terminal is restricted from initiating uplink.

[0193] 15) When the first configuration information includes the first UAC prohibition factor, the terminal generates a random number between 0 and 1 when performing an access barring check, and when the random number is less than the first UAC prohibition factor, the terminal initiates access; or, when the random number is greater than or equal to the first UAC prohibition factor, the terminal cancels access.

[0194] Specifically, after the terminal receives the first configuration information, when the first configuration information includes the first UAC prohibition factor, the terminal generates a random number from 0 to 1 when performing an access barring check. When the random number is less than the first UAC prohibition factor, the terminal can initiate access; or, when the random number is greater than or equal to the first UAC prohibition factor, the terminal can cancel access. Through the UAC mechanism, the terminal resides in the NTZ restricted cell, but the terminal is restricted from initiating uplink.

[0195] For example, the UAV UE receives the first configuration information through the system information, wherein the first configuration information includes the first UAC prohibition factor; the UAV UE generates a random number from 0 to 1 when performing the access barring check, and when the random number is less than the first UAC prohibition factor, the access is allowed and the terminal can initiate the access; or, when the random number is greater than or equal to the first UAC prohibition factor, the terminal can cancel the access. In order to prevent the UAV UE from accessing the NTZ restricted cell as much as possible, the network side device will be equipped with a very low first UAC prohibition factor or the first UAC prohibition factor is equal to 0, then the random number from 0 to 1 generated by the UAV UE when performing the access barring check will be greater than the first UAC prohibition factor, and the terminal will cancel the access.

[0196] Optionally, the method further comprises:

[0197] a) The terminal receives second configuration information sent by the network side device, where the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographical location.

[0198] Specifically, the terminal is an idle or inactive terminal located in a cell at the edge of the NTZ (i.e., part of the area is covered by the NTZ), and the terminal enters or is about to enter a cell covered by the NTZ. The network side device sends second configuration information to the terminal, and the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographical location; the terminal receives the second configuration information sent by the network side device.

[0199] b) The terminal performs a second operation based on the second configuration information; the second operation includes at least one of the following: triggering measurement report reporting; triggering cell reselection; prohibiting staying in the current serving cell; prohibiting initiating access in the current serving cell; determining that the current serving cell is an acceptable cell.

[0200] Specifically, after the terminal receives the second configuration information sent by the network side device, since the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographic location, the terminal can perform a second operation according to the second configuration information; the second operation includes at least one of the following: triggering measurement report reporting; triggering cell reselection, that is, reselecting to a non-NTZ covered cell; prohibiting staying in the current service cell, that is, not allowing staying in the current service cell; prohibiting initiating access in the current service cell; determining that the current service cell is an acceptable cell. Through the second configuration information, the terminal is instructed to trigger cell reselection or measurement report reporting based on the current geographic location, so that after entering the NTZ covered cell, the terminal is restricted to initiating uplink in the NTZ covered cell or reselecting to a non-NTZ covered cell to avoid interference with adjacent cells.

[0201] Optionally, the second configuration information includes at least one of the following:

[0202] (1) First reference position information for indicating a first reference position.

[0203] Specifically, the first reference position information is used to indicate the first reference position. For a terminal in the connected state, the terminal can determine the distance between the current geographical location and the first reference position based on the current geographical location.

[0204] For example, if the distance between the current geographical location of the terminal and the first reference position is less than or equal to a fourth distance threshold, it indicates that the terminal enters or is about to enter the NTZ coverage cell. If the distance between the current geographical location of the terminal and the first reference position is greater than the fourth distance threshold, it indicates that the terminal leaves or is about to leave the NTZ coverage cell. The fourth distance threshold can be network-configured or protocol-agreed.

[0205] (2) A first event, where the first event includes at least one of the following parameters: a first distance threshold, a first leave reporting indication, a first hysteresis factor (such as hysteresisLocation) and a first time hysteresis (such as TimeToTrigger, TTT).

[0206] Specifically, the first distance threshold is a preset threshold Thresh, and the first leave reporting indication is ReportOnLeave. When the value of ReportOnLeave is set to True, the first event satisfies the event leave condition, and the terminal triggers the reporting of a measurement report.

[0207] The entry condition for the first event is: ML + hysteresisLocation < Thresh, and the leave condition for the first event is: ML - hysteresisLocation > Thresh, where ML represents the distance between the current geographical location of the terminal and the first reference position.

[0208] (3) A second event, where the second event is a combined event of the first event and a height event. The second event includes at least one of the following parameters: a second distance threshold for the first event, a height threshold for the height event, a second leave reporting indication, a second hysteresis factor, and a second time hysteresis.

[0209] Specifically, the second event is a combination of the first event and the altitude event, the altitude event is an event in the existing mechanism, for example, the altitude event is Event H1 or Event H2, and the second event is the first event + Event H1, the first event + Event H2, the first event + Event H1 + Event H2. The second event includes at least one of the following parameters: a second distance threshold Thresh for the first event, an altitude threshold for the altitude event, a second departure report ReportOnLeave indication, a second hysteresis factor (for example, location hysteresis (hysteresisLocation)), and a second time hysteresis (for example, trigger time (TimeToTrigger, TTT)).

[0210] The second leaving report ReportOnLeave indication includes any of the following items: when one of the first event and the high event meets the leaving condition, reporting the measurement report; optionally, the terminal indicates to the network side device which specific event meets the leaving condition; when both the first event and the high event meet the leaving condition at the same time, reporting the measurement report; when a specific event meets the leaving condition, reporting the measurement report, wherein the specific event may be a network configuration or protocol agreement.

[0211] The event entry condition of the second event is: the first event and the height event simultaneously meet the entry condition; the event exit condition of the second event includes any of the following: the first event and the height event simultaneously meet the exit condition; any one of the first event and the height event meets the exit condition; a specific event among the first event and the height event meets the exit condition.

[0212] (4) Height area.

[0213] Specifically, the height area is used to indicate that the terminal is within the range of the height area. If the terminal enters the first cell, leaves the first cell, or triggers the first event, the terminal may trigger reporting of the measurement report.

[0214] (5) Absolute altitude value.

[0215] Specifically, the absolute altitude value is used to indicate that the flight altitude of the terminal is greater than or equal to the absolute altitude value. If the terminal enters the first cell, leaves the first cell, or triggers the first event, the terminal can trigger reporting of the measurement report.

[0216] (6) A specific event indication, which is used to indicate that when a specific event among the first event and the high-level event satisfies the departure condition, the second event satisfies the departure condition.

[0217] Specifically, the specific event is the first event or a high-level event indicated, and the specific event may be a network configuration or a protocol agreement.

[0218] (7) Third distance threshold.

[0219] Specifically, for a terminal that is idle or inactive, when the distance between the current geographic location of the terminal and the first reference location is less than or equal to a third distance threshold, it indicates that the terminal has entered or is about to enter a cell covered by the NTZ; when the distance between the current geographic location of the terminal and the first reference location is greater than the third distance threshold, it indicates that the terminal has left or is about to leave the cell covered by the NTZ. The third distance threshold may be a network configuration or a protocol agreement.

[0220] Optionally, the second configuration information is carried in at least one of the following ways: system information; dedicated signaling; non-access stratum (NAS) message.

[0221] Optionally, the terminal performs a second operation based on the second configuration information, including:

[0222] In a case where the second configuration information includes the first reference location information and the third distance threshold, when the terminal is in an idle state or an inactive state, and the distance between the current geographical location and the first reference location is less than or equal to the third distance threshold, the terminal performs at least one of the following operations: triggering cell reselection; prohibiting staying in the current service cell; prohibiting initiating access in the current service cell; and determining that the current service cell is an acceptable cell.

[0223] Specifically, after the terminal receives the second configuration information, when the second configuration information includes the first reference location information and the third distance threshold, when the terminal is idle or inactive, and the distance between the current geographical location and the first reference location is less than or equal to the third distance threshold, that is, when the terminal enters or is about to enter the NTZ coverage cell, the terminal can perform at least one of the following operations:

[0224] 1) Triggering cell reselection, i.e. reselecting to a cell not covered by the NTZ;

[0225] 2) It is forbidden to stay in the current serving cell, that is, it is not allowed to stay in the current serving cell (NTZ coverage cell);

[0226] 3) Prohibit access in the current serving cell;

[0227] 4) Determine that the current serving cell is an acceptable cell.

[0228] Through the second configuration information, the terminal is instructed to trigger cell reselection based on the current geographic location and reselect to a cell not covered by the NTZ. Alternatively, after entering the cell covered by the NTZ (i.e., the current service cell), the terminal can reside in the cell covered by the NTZ (i.e., the current service cell), but is restricted to initiating access in the cell covered by the NTZ (i.e., the current service cell) to avoid interference with adjacent cells. Alternatively, when the signal quality of the cell not covered by the NTZ is too poor and it is impossible to reside normally, the cell covered by the NTZ (i.e., the current service cell) is determined to be a receivable cell to ensure normal terminal services.

[0229] Optionally, the terminal performs a second operation based on the second configuration information, including:

[0230] When the terminal is in a connected state, the terminal triggers measurement report reporting when the terminal satisfies any of the following conditions:

[0231] A first event entry condition, and within the first time delay, the first event entry condition is always satisfied;

[0232] a first event leaving condition, and within the first time delay, the first event leaving condition is always satisfied, and the first leaving reporting indication is true;

[0233] The second event entry condition includes the first event entry condition and the altitude event entry condition being satisfied at the same time, and the second event entry condition is always satisfied within the second time delay;

[0234] A second event leaving condition, and the second leaving condition is always satisfied within a second time delay, and the second leaving reporting indication is true; wherein the second event leaving condition includes the first event leaving condition and the height event leaving condition being satisfied at the same time, or any one of the first event leaving condition and the height event leaving condition being satisfied, or the leaving condition of a specific event among the first event and the height event being satisfied, and the specific event is indicated by a network side device or agreed upon by a protocol;

[0235] a first event entry condition, and the current altitude of the terminal is in the altitude zone, and within the first time delay, the first event entry condition is always satisfied and the current altitude of the terminal is always in the altitude zone;

[0236] The current height of the terminal does not satisfy the height region, and within the first time delay, the current height of the terminal does not satisfy the height region all the time;

[0237] a first event entry condition, and the current height of the terminal is greater than or equal to the absolute height value, and within the first time delay, the first event entry condition is always satisfied and the current height of the terminal is always greater than or equal to the absolute height value;

[0238] The current height of the terminal is less than the absolute height value, and within the first time delay, the current height of the terminal is always less than the absolute height value.

[0239] Specifically, the measurement report is used to indicate that the terminal has entered or is about to enter the first cell, has left or is about to leave the first cell. For a connected terminal in a cell at the edge of the NTZ (only a portion of the area is covered by the NTZ), when the terminal in the cell enters or is about to enter the first cell, the terminal receives the second configuration information.

[0240] After the terminal receives the second configuration information, when the terminal meets the first event entry condition and the first event entry condition is always met within the first time delay, the terminal triggers the measurement report reporting;

[0241] Alternatively, when the terminal satisfies the first event leaving condition, and within the first time delay, the first event leaving condition is always satisfied, and the first leaving reporting indication is true, the terminal triggers the measurement report reporting;

[0242] Alternatively, the terminal satisfies the second event entry condition, including the first event entry condition and the height event entry condition being satisfied at the same time, and the second event entry condition is always satisfied within the second time delay;

[0243] Alternatively, when the terminal satisfies the second event leaving condition, and the second leaving condition is always satisfied within the second time delay, and the second leaving reporting indication is true, the terminal triggers the measurement report reporting; wherein the second event leaving condition includes the first event leaving condition and the high event leaving condition being satisfied at the same time, or any one of the first event leaving condition and the high event leaving condition being satisfied, or the leaving condition of a specific event in the first event and the high event being satisfied, and the specific event is indicated by the network side device or agreed upon by the protocol;

[0244] Alternatively, when the terminal meets the first event entry condition and the current height of the terminal is in the height area, and within the first time delay, the first event entry condition is always met and the current height of the terminal is always in the height area, the terminal triggers the measurement report to be reported;

[0245] Alternatively, when the current height of the terminal does not satisfy the height area, and within the first time delay, the current height of the terminal still does not satisfy the height area, the terminal triggers the measurement report to be reported;

[0246] Alternatively, when the terminal meets the first event entry condition, and the current height of the terminal is greater than or equal to the absolute height value, and within the first time hysteresis, the first event entry condition is always met and the current height of the terminal is always greater than or equal to the absolute height value, the terminal triggers the measurement report to be reported;

[0247] Alternatively, when the current height of the terminal is less than the absolute height value, and within the first time delay, the current height of the terminal is always less than the absolute height value, the terminal triggers the measurement report to be reported.

[0248] By triggering the reporting of the measurement report, the network side device is informed that the terminal is about to enter the first cell, and then the network side device switches the terminal to a cell with a frequency that is not covered by the restricted frequency band of NTZ or is not covered by the restricted frequency band of NTZ, avoiding interference with adjacent cells.

[0249] Optionally, the measurement report reported by the terminal can also instruct the network side device to allocate uplink resources and resource size to the terminal, so that the terminal can send uplink data as quickly as possible before entering the first cell, and no longer send uplink data after entering the first cell to avoid interference with adjacent cells.

[0250] Optionally, when the terminal meets the first event or the second event entry condition, the terminal may notify a medium access control (MAC) layer to trigger reporting of a buffer status report (BSR).

[0251] Figure 3 This is a second flow chart of the terminal control method provided in the embodiment of the present application, such as Figure 3 As shown, the method includes step 301; wherein:

[0252] Step 301, the network side device sends first configuration information to the terminal; the first configuration information is related to the forbidden transmission zone NTZ; the first configuration information is used to instruct the terminal to perform a first operation, and the first operation includes at least one of the following: prohibiting staying in the first cell; prohibiting measuring the first frequency point when selecting or reselecting the cell; prohibiting selecting the first cell when selecting or reselecting the cell; starting to measure the first cell; prohibiting initiating access in the first cell; wherein, the first frequency point is a frequency point covered by the restricted frequency band of the NTZ; the first cell is a cell whose frequency band is completely covered by the restricted frequency band of the NTZ or operates at a frequency point covered by the restricted frequency band of the NTZ.

[0253] Specifically, the network side device sends the first configuration information to the terminal, and the first configuration information is related to the NTZ, then the terminal can receive the first configuration information sent by the network side device. After receiving the first configuration information sent by the network side device, the terminal can perform a first operation according to the first configuration information; wherein the first operation includes at least one of the following: prohibiting staying in the first cell; prohibiting measuring the first frequency point when selecting or reselecting the cell; prohibiting selecting the first cell when selecting or reselecting the cell; starting to measure the first cell; prohibiting initiating access in the first cell; wherein the first frequency point is a frequency point covered by the restricted frequency band of the NTZ, that is, at the first frequency point, the terminal is prohibited from performing frequency point measurement; the first cell is a cell whose frequency band is completely covered by the restricted frequency band of the NTZ or works at a frequency point covered by the restricted frequency band of the NTZ, that is, in the first cell, the terminal is prohibited from staying, allowed to stay, or prohibited from selecting, starting measurement or initiating access when selecting or reselecting the cell, so as to restrict the behavior of the terminal in the prohibited transmission area.

[0254] In the terminal control method provided in the embodiment of the present application, the first configuration information related to NTZ is sent to the terminal through the network side device, and the first configuration information is used to instruct the terminal to perform a first operation, and the first operation includes at least one of the following: prohibiting staying in the first cell; prohibiting measuring the first frequency point when selecting or reselecting the cell; prohibiting selecting the first cell when selecting or reselecting the cell; starting to measure the first cell; prohibiting initiating access in the first cell; wherein the first frequency point is a frequency point covered by the restricted frequency band of NTZ; the first cell is a cell whose frequency band is completely covered by the restricted frequency band of NTZ or works at a frequency point covered by the restricted frequency band of NTZ. Since the first configuration information is related to NTZ, the terminal ensures that the terminal is not allowed to stay in the first cell, initiate uplink access, perform uplink transmission, or select the first cell when selecting / reselecting the cell, or the like, or reduces the terminal's behavior or probability, thereby limiting the terminal's behavior in the prohibited transmission area and avoiding interference to adjacent cells.

[0255] Optionally, the first configuration information includes at least one of the following:

[0256] (1) A cell access prohibition parameter, used to indicate whether the terminal is prohibited from staying in the first cell.

[0257] For example, the cell barring access parameter may be cellBarredUAV. When the value of cellBarredUAV is set to barred, it indicates that the AV UE is not allowed to reside in the first cell. When the value of cellBarredUAV is set to not barred, the UAV UE is allowed to reside in the first cell.

[0258] (2) a cell prohibited transmission list, including the first cell, and the cell in the cell prohibited transmission list can only be the first cell.

[0259] Specifically, the first cell is a cell whose frequency band is completely covered by the restricted frequency band of NTZ or operates at a frequency point covered by the restricted frequency band of NTZ. The cells in the cell prohibition list can only be cells whose frequency band is completely covered by the restricted frequency band of NTZ or operate at a frequency point covered by the restricted frequency band of NTZ.

[0260] (3) A list of cells allowed to transmit, including cells that are not covered by the restricted frequency band of the NTZ or cells operating at frequencies that are not covered by the restricted frequency band of the NTZ, and the cells in the list of cells allowed to transmit can only be cells that are not covered by the restricted frequency band of the NTZ or cells operating at frequencies that are not covered by the restricted frequency band of the NTZ.

[0261] Specifically, the cells in the cell allowed to transmit list can only be cells that are not covered by the restricted frequency band of the NTZ or operate at frequencies that are not covered by the restricted frequency band of the NTZ, that is, the cells in the cell allowed to transmit list are not restricted from transmitting.

[0262] (4) A first frequency point list, including the first frequency point, and the frequency point in the first frequency point list can only be the first frequency point.

[0263] Specifically, the frequencies in the first frequency list can only be frequencies covered by the restricted frequency band of the NTZ.

[0264] (5) A first high priority frequency list includes frequencies used to start high priority frequency measurement. The first high priority frequency list does not include the first frequency.

[0265] Specifically, the frequencies included in the first high priority frequency list are frequencies used when the NAV UE starts high priority frequency measurement. The first high priority frequency list does not include the first frequency, that is, does not include the NTZ frequency.

[0266] (6) A first low-priority frequency point list includes frequencies used to start low-priority frequency point measurement, and the first low-priority frequency point list does not include the first frequency point.

[0267] Specifically, the frequencies included in the first low priority frequency list are frequencies used when the NAV UE starts low priority frequency measurement. The first low priority frequency list does not include the first frequency, that is, does not include the NTZ frequency.

[0268] (7) A first frequency list of equal priority includes frequencies used to start measurement of equal-priority different-frequency frequencies, wherein the first frequency list of equal priority does not include the first frequency.

[0269] Specifically, the frequencies included in the first equal priority frequency list are the frequencies used when the NAV UE initiates equal priority inter-frequency frequency measurement. The first equal priority frequency list does not include the first frequency, that is, does not include the NTZ frequency.

[0270] (8) A first measurement start threshold, used to indicate a threshold for starting the measurement of the first cell.

[0271] Specifically, the first measurement start threshold is used to indicate the threshold for starting the first cell measurement, that is, the threshold for starting the measurement of the NTZ covered cell. For example, the network side device can configure a relatively small first measurement start threshold to ensure that the terminal can select the NTZ restricted cell only when the signal quality of the serving cell is too poor and may not be able to stay normally.

[0272] (9) First start threshold offset.

[0273] Specifically, when the first configuration information includes the first start threshold offset, the terminal subtracts the first start threshold offset from the same-frequency and / or different-frequency measurement start threshold to obtain an updated same-frequency and / or different-frequency measurement start threshold, and starts measurement according to the updated same-frequency and / or different-frequency measurement start threshold.

[0274] (10) A first offset list, comprising at least one offset corresponding to at least one cell in the cell ban list, wherein the offsets in the first offset list are in one-to-one correspondence with the cells in the cell ban list, and the offsets in the first offset list are offsets between the corresponding cell and the current resident cell of the terminal.

[0275] Specifically, the offset included in the first bias list is the offset between the corresponding cell in the cell ban list and the current resident cell of the terminal. The offset in the first bias list is in a one-to-one correspondence with the cell in the cell ban list. For example, the offset 1 in the first bias list corresponds to the cell 1 in the cell ban list.

[0276] (11) A first offset, used to represent an offset between each cell in the cell prohibition list and the current resident cell of the terminal.

[0277] Specifically, the first offset is used to represent the offset between each cell in the cell prohibition list and the current resident cell of the terminal, that is, the first offset corresponds to multiple cells in the cell prohibition list, which is a one-to-many correspondence relationship.

[0278] (12) A first minimum reception quality or level, used to determine a cell selection criterion when selecting a cell.

[0279] Specifically, the cell selection criterion is the S criterion. When the first configuration information includes the first minimum reception quality or level, the terminal calculates the S criterion according to the first minimum reception quality or level when selecting a cell.

[0280] (13) The unified access control mechanism UAC access identifier bar parameter is used to indicate whether access corresponding to the access identifier of the terminal is allowed.

[0281] For example, the UAC access identifier bar parameter may be UAC-BarringForAccessIdentity. In the existing mechanism, the parameter is set to 7 bits, and the 7 bits correspond to access identifiers 1, 2, and 11 to 15, respectively. When a new access identifier is introduced for UAVUE, the UAC access identifier bar parameter may be set to 8 bits (bits), with an additional 1 bit corresponding to the UAV UE, or may be indicated by an additional 1 bit. In the above bit representation, 0 indicates that the terminal is allowed to access with the corresponding access identifier.

[0282] (14) A first UAC barring factor, which is used to represent the access probability of the terminal when performing an access barring check.

[0283] For example, the first UAC barring factor may be UAC-BarringFactorUAV. When the UAV UE performs an accessbarring check, the UAV UE generates a random number between 0 and 1. When the random number is smaller than the first UAC barring factor, the UAV UE considers that the access is allowed.

[0284] (15) First absolute threshold.

[0285] For example, when the signal quality of the NTZ restricted cell is greater than the first absolute threshold, only the non-NTZ restricted cells are sorted according to the R criterion, and the UAV UE selects the strongest cell based on the sorting result.

[0286] Optionally, the first configuration information is carried in at least one of the following ways:

[0287] (a) System information;

[0288] (b) dedicated signaling;

[0289] (c)NAS message.

[0290] Optionally, the network side device sends second configuration information to the terminal; the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographical location.

[0291] Specifically, the network side device can also send second configuration information to the terminal; wherein, the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographic location, the terminal is an idle or inactive terminal located in a cell at the edge of the NTZ (i.e., part of the area is covered by the NTA), and the terminal enters or is about to enter a cell covered by the NTZ.

[0292] The terminal receives the second configuration information sent by the network side device. Since the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographical location, the terminal can perform a second operation according to the second configuration information; the second operation includes at least one of the following: triggering measurement report reporting; triggering cell reselection, that is, reselecting to a non-NTZ covered cell; prohibiting staying in the current service cell, that is, not allowing staying in the current service cell; prohibiting initiating access in the current service cell; determining that the current service cell is an acceptable cell. Through the second configuration information, the terminal is instructed to trigger cell reselection or measurement report reporting based on the current geographical location, so that after entering the NTZ covered cell, the terminal is restricted to initiating uplink in the NTZ covered cell or reselecting to a non-NTZ covered cell to avoid interference with adjacent cells.

[0293] Optionally, the second configuration information includes at least one of the following:

[0294] (1) First reference position information, used to indicate the first reference position.

[0295] Specifically, the first reference location information is used to indicate the first reference location. For a terminal in a connected state, the terminal can determine the distance between the current geographical location and the first reference location according to the current geographical location.

[0296] For example, if the distance between the current geographic location of the terminal and the first reference location is less than or equal to the fourth distance threshold, it means that the terminal has entered or is about to enter the NTZ coverage cell. If the distance between the current geographic location of the terminal and the first reference location is greater than the fourth distance threshold, it means that the terminal has left or is about to leave the NTZ coverage cell. The fourth distance threshold may be a network configuration or protocol agreement.

[0297] (2) A first event, wherein the first event includes at least one of the following parameters: a first distance threshold, a first departure reporting indication, a first hysteresis factor (eg, location hysteresis (hysteresisLocation)) and a first time hysteresis (eg, trigger time (TimeToTrigger, TTT)).

[0298] Specifically, the first distance threshold is a preset threshold Thresh, and the first leave reporting indication is ReportOnLeave. When the value of ReportOnLeave is set to True, the first event meets the event leave condition, and the terminal triggers the reporting of a measurement report.

[0299] The entry condition for the first event is: ML + hysteresisLocation < Thresh, and the leave condition for the first event is: ML - hysteresisLocation > Thresh, where ML represents the distance between the current geographical location of the terminal and the first reference location.

[0300] (3) The second event, which is a combined event of the first event and the height event. The second event includes at least one of the following parameters: a second distance threshold for the first event, a height threshold for the height event, a second leave reporting indication, a second hysteresis factor, and a second time hysteresis.

[0301] Specifically, the second event is a combined event of the first event and the height event. The height event is an event in the existing mechanism. For example, the height event is Event H1 or Event H2, and the second event is the first event + Event H1, the first event + Event H2, or the first event + Event H1 + Event H2. The second event includes at least one of the following parameters: a second distance threshold Thresh for the first event, a height threshold for the height event, a second leave reporting ReportOnLeave indication, a second hysteresis factor (such as position hysteresis (hysteresisLocation)), and a second time hysteresis (such as trigger time (TimeToTrigger, TTT)).

[0302] The second leave reporting ReportOnLeave indication includes any of the following: when one of the first event and the height event meets the leave condition, report a measurement report; optionally, the terminal indicates to the network-side device which specific event meets the leave condition; when both the first event and the height event meet the leave condition simultaneously, report a measurement report; when a specific event meets the leave condition, report a measurement report, where the specific event can be network-configured or protocol-agreed.

[0303] The entry condition for the second event is: both the first event and the height event meet the entry condition simultaneously; the leave conditions for the second event include any of the following: both the first event and the height event meet the leave condition simultaneously; any one of the first event and the height event meets the leave condition; a specific event among the first event and the height event meets the leave condition.

[0304] (4) Height area.

[0305] Specifically, the height area is used to indicate that within the range of the terminal height area, if the terminal enters the first cell, leaves the first cell, or triggers the first event, the terminal can trigger the reporting of the measurement report.

[0306] (5) Absolute altitude value.

[0307] Specifically, the absolute altitude value is used to indicate that the flight altitude of the terminal is greater than or equal to the absolute altitude value. If the terminal enters the first cell, leaves the first cell, or triggers the first event, the terminal can trigger reporting of the measurement report.

[0308] (6) A specific event indication, which is used to indicate that when a specific event among the first event and the high-level event satisfies the departure condition, the second event satisfies the departure condition.

[0309] Specifically, the specific event is the first event or a high-level event indicated, and the specific event may be a network configuration or a protocol agreement.

[0310] (7) Third distance threshold.

[0311] Specifically, for a terminal that is idle or inactive, when the distance between the current geographic location of the terminal and the first reference location is less than or equal to a third distance threshold, it indicates that the terminal has entered or is about to enter a cell covered by the NTZ; when the distance between the current geographic location of the terminal and the first reference location is greater than the third distance threshold, it indicates that the terminal has left or is about to leave the cell covered by the NTZ. The third distance threshold may be a network configuration or a protocol agreement.

[0312] Optionally, the second configuration information is carried in at least one of the following ways: system information; dedicated signaling; non-access layer NAS message.

[0313] Figure 4 This is a flowchart of the terminal control method provided in the embodiment of the present application. Figure 4 As shown, the method includes steps 401 and 402; wherein:

[0314] Step 401: The terminal receives second configuration information sent by the network side device, where the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographical location;

[0315] Step 402: The terminal performs a second operation based on the second configuration information; the second operation includes at least one of the following: triggering measurement report reporting; triggering cell reselection; prohibiting staying in the current serving cell; prohibiting initiating access in the current serving cell; determining that the current serving cell is an acceptable cell.

[0316] In the terminal control method provided in the embodiment of the present application, the terminal receives the first configuration information related to the NTZ sent by the network side device, and the terminal performs a first operation based on the first configuration information, and the first operation includes at least one of the following: prohibiting staying in the first cell; prohibiting measuring the first frequency point when selecting or reselecting the cell; prohibiting selecting the first cell when selecting or reselecting the cell; starting to measure the first cell; prohibiting initiating access in the first cell; wherein the first frequency point is a frequency point covered by the restricted frequency band of the NTZ; the first cell is a cell whose frequency band is completely covered by the restricted frequency band of the NTZ or works at a frequency point covered by the restricted frequency band of the NTZ. Since the first configuration information is related to the NTZ, the network side device can send the first configuration information to the terminal to ensure that the terminal is not allowed or the terminal is not allowed to stay in the first cell or initiate uplink access, perform uplink transmission, or select the first cell during cell selection / reselection, etc., or the probability of the terminal being selected is reduced, thereby restricting the behavior of the terminal in the prohibited transmission area and avoiding interference with adjacent cells.

[0317] The terminal receives the second configuration information sent by the network side device, and the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographic location. The terminal can perform a second operation according to the second configuration information; the second operation includes at least one of the following: triggering measurement report reporting; triggering cell reselection; prohibiting resident in the current service cell; prohibiting initiating access in the current service cell; determining that the current service cell is an acceptable cell. Since the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographic location, the network side device can limit the terminal from triggering measurement report reporting in the first cell, triggering cell reselection, prohibiting resident in the current service cell, prohibiting initiating access in the current service cell, or determining that the current service cell is an acceptable cell by sending the second configuration information to the terminal, so as to avoid interference with adjacent cells.

[0320] Step 502, the terminal receives the first configuration information sent by the network side device, and performs a first operation based on the first configuration information; the first operation includes at least one of the following: prohibiting staying in the first cell; prohibiting measuring the first frequency point when selecting or reselecting the cell; prohibiting selecting the first cell when selecting or reselecting the cell; starting measuring the first cell; prohibiting initiating access in the first cell; wherein the first frequency point is a frequency point covered by the restricted frequency band of the NTZ; the first cell is a cell whose frequency band is completely covered by the restricted frequency band of the NTZ or operates at a frequency point covered by the restricted frequency band of the NTZ.

[0322] Step 601: A network-side device sends second configuration information to a terminal, where the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographical location.

[0323] Step 602: The terminal performs a second operation based on the second configuration information; the second operation includes at least one of the following: triggering measurement report reporting; triggering cell reselection; prohibiting staying in the current serving cell; prohibiting initiating access in the current serving cell; determining that the current serving cell is an acceptable cell.

[0325] Step 701: A network-side device sends second configuration information to a terminal, where the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographical location.

[0326] Step 702: When the second configuration information includes the first reference location information and the third distance threshold, when the terminal is in an idle state or an inactive state, and the distance between the current geographical location and the first reference location is less than or equal to the third distance threshold, the terminal performs at least one of the following operations: triggering cell reselection; prohibiting staying in the current service cell; prohibiting initiating access in the current service cell; determining that the current service cell is an acceptable cell.

[0327] Figure 8 This is a fourth schematic diagram of interaction between a terminal and a network device provided in an embodiment of the present application, such as Figure 8 As shown, it includes steps 801 and 802; wherein,

[0328] Step 801: A network-side device sends second configuration information to a terminal, where the second configuration information is used to indicate whether the terminal triggers cell reselection or measurement report reporting based on the current geographical location.

[0329] Step 802: When the terminal is in a connected state, the terminal triggers a measurement report when any of the following items is met: a first event entry condition, and within a first time delay, the first event entry condition is always met; a first event exit condition, and within the first time delay, the first event exit condition is always met, and the first exit report indication is true; a second event entry condition, including the first event entry condition and the altitude event entry condition are met at the same time, and within the second time delay, the second event entry condition is always met; a second event exit condition, and within the second time delay, the second exit condition is always met, and the second exit report indication is true; wherein the second event exit condition includes the first event exit condition and the altitude event leaving condition are met at the same time, or any one of the first event leaving condition and the altitude event leaving condition is met, or the leaving condition of a specific event among the first event and the altitude event is met, and the specific event is indicated by the network side device or agreed upon by the protocol; the current altitude of the terminal does not meet the altitude area, and within the first time delay, the current altitude of the terminal always does not meet the altitude area; the first event entry condition, and the current altitude of the terminal is greater than or equal to the absolute altitude value, and within the first time delay, the first event entry condition is always met and the current altitude of the terminal is always greater than or equal to the absolute altitude value; the current altitude of the terminal is less than the absolute altitude value, and within the first time hysteresis, the current altitude of the terminal is always less than the absolute altitude value.

[0330] Next, the terminal control method provided in the embodiment of the present application is further described through specific examples.

[0331] Embodiment 1: through cellbarred, UAV UE is not allowed to stay in a cell where the frequency band is completely covered by the restricted frequency band of NTZ

[0332] Step 1: The UAV UE receives first configuration information through a system message of cell 1 and receives cellBarred through a MIB message, wherein the first configuration information includes cellBarredUAV.

[0333] Step 2: The UAV UE performs at least one of the following operations based on the cellBarredUAV:

[0334] Step 21, the UAV UE ignores cellBarred in the MIB message. When the value of cellBarredUAV is set to barred, the UAV UE is not allowed to reside in cell 1; when the value of cellBarredUAV is set to not barred, the UAV UE is allowed to reside in cell 1;

[0335] Step 22: The UAV UE does not ignore the cellBarred in the MIB message, including one of the following situations:

[0336] The cellBarred in the MIB message is set to barred, the value of cellBarredUAV is set to barred, and the UAVUE is not allowed to reside in cell 1;

[0337] The cellBarred value in the MIB message is set to barred, and the value of cellBarredUAV is set to not barred. The UAV UE is not allowed to reside in cell 1;

[0338] The cellBarred value in the MIB message is set to not barred, and the value of cellBarredUAV is set to barred. The UAV UE is not allowed to reside in cell 1;

[0339] The cellBarred in the MIB message is set to not barred, the value of cellBarredUAV is set to notbarred, and the UAV UE is allowed to reside in cell 1.

[0340] Embodiment 1 restricts UAV UEs from residing in cells covered by the restricted frequency band of the NTZ, thereby restricting the opportunities for AV UEs to initiate uplink in cells covered by the restricted frequency band of the NTZ.

[0341] Embodiment 2: When selecting or reselecting a cell, for the measurement of high priority frequencies, the UAV UE is not allowed to measure frequencies including those restricted by the NTZ

[0342] Step a: The UAV UE receives first configuration information and an inter-frequency carrier frequency list through a system message, wherein the first configuration information includes a first frequency point list or a first high priority frequency point list.

[0343] Step b: The UAV UE performs one of the following operations based on the first configuration information:

[0344] When the first configuration includes the first frequency list, the UAV UE does not measure the frequencies in the first frequency list included in the high priority frequency list when measuring the high priority frequency in the inter-frequency carrier frequency list;

[0345] When the first configuration includes a first high priority frequency list, the UAV UE performs high priority frequency measurement on the frequencies in the first high priority frequency list.

[0346] Embodiment 3: During cell selection or reselection, for measurements of frequencies of equal priority or lower priority, UAV UE is not allowed to measure frequencies including NTZ restrictions

[0347] Step 1) The UAV UE receives first configuration information and an inter-frequency carrier frequency list through a system message, wherein the first configuration information includes a first frequency list, a first low-priority frequency list, or a first equal-priority frequency list.

[0348] Step 2) When the serving cell signal quality of the UAV UE is lower than the equal or lower priority frequency measurement threshold, the UAV UE performs one of the following operations:

[0349] When the first configuration includes the first frequency list, the UAV UE starts measuring the same priority inter-frequency and low priority frequencies in the inter-frequency carrier frequency list without measuring the frequencies in the first frequency list among the low priority frequencies;

[0350] When the first configuration includes a first low priority frequency list, the UAV UE performs low priority frequency measurement on the frequencies in the first low priority frequency list;

[0351] When the first configuration includes a first equal priority frequency list, the UAV UE performs equal priority frequency measurement on the frequencies in the first equal priority frequency list.

[0352] Embodiment 4: UAV UE is not allowed to select or reselect to a cell restricted by NTZ

[0353] Step a) The UAV UE receives first configuration information, a same-frequency neighbor cell list and an inter-frequency carrier frequency list through a system message, wherein the first configuration information includes a cell prohibited transmission list and a first offset list.

[0354] Step b) The UAV UE starts measuring the high priority frequency in the inter-frequency carrier frequency list. When the signal quality of a cell in the high priority frequency is greater than the high priority signal quality absolute threshold, and the cell in the high priority frequency does not belong to the cell ban list, the UAV UE reselects to the cell in the high priority frequency.

[0355] Step c) When the signal quality of the serving cell of the UAV UE is lower than the same-frequency reselection measurement start threshold, the same priority or low priority reselection measurement start threshold, the UE starts the same-frequency, different-frequency, same priority or low priority frequency point measurement. The UAV UE sorts by the R criterion to exclude the cells in the cell ban list; or, the UAV UE sorts by the cell ban list and the corresponding first offset list or the first offset, wherein the cells in the cell ban list and the offsets in the first offset list are in a one-to-one correspondence; for example, cell 1 in the cell ban list corresponds to offset 1 in the first offset list; for another example, if the first offset is configured, the first offset can be used for all cells in the cell ban list. In order to prevent the UAV UE from reselecting to a cell in the cell ban list, the network side device will allocate a large offset 1 to the UAV UE, calculate the R criterion by the offset 1, and the UE performs cell reselection.

[0356] Embodiment 5: Do not select a cell restricted by NTZ when selecting a cell

[0357] Step (1) The UAV UE receives first configuration information through a system message, wherein the first configuration information includes a cell prohibited list or a first minimum reception quality or level;

[0358] Step (2) The UAV UE performs one of the following operations:

[0359] When the first configuration information includes a cell prohibition list, the UAV UE excludes cells in the cell prohibition list when performing R criterion sorting;

[0360] When the first configuration information includes the first minimum reception quality or level, the UAV UE uses the first minimum reception quality or level to calculate the R criterion. In order to increase the difficulty of the UAV selecting the NTZ restricted cell, the network side device configures a large value for the first minimum reception quality or level.

[0361] Example 6: Start NTZ restricted cell measurement

[0362] Step 1: The UAV UE receives first configuration information through a system message, wherein the first configuration information includes a first measurement start threshold and a cell prohibited list.

[0363] Step 2: When the signal quality of the serving cell of the UAV UE is lower than the same-frequency reselection measurement start threshold, the same priority or low priority reselection measurement start threshold in the existing mechanism, the UE starts non-NTZ restricted cell measurement.

[0364] Step 3: The signal quality of the serving cell further deteriorates, and the signal quality of the serving cell of the UAV UE is lower than the first measurement start threshold, and the UAV UE starts the NTZ restricted cell measurement (for example, the cells in the cell prohibited list).

[0365] Optionally, the UAV UE may also start the measurement of the NTZ restricted cell by subtracting the first measurement start offset from the measurement start threshold.

[0366] In this sixth embodiment, the network side device may be configured with a relatively low first measurement start threshold to ensure that the UAV UE may select the NTZ restricted cell only when the signal quality of the serving cell is too poor and the UAV UE may not be able to reside normally.

[0367] Optionally, in the above embodiments 1 to 4, the first configuration information may not be effective under certain conditions. For example, if the UAV UE cannot find any suitable serving cell through the methods described in the above embodiments 1 to 4, the UAV UE may ignore the barred of cellBarredUAV in the system message or the cell banned list, etc.; for another example, for the UAV UE, when cellBarredUAV is set to barred, or any one of the parameter values ​​of cellBarred and cellBarredUAV in the MIB message is set to barred, or for the cells in the cell banned list, the UE may consider the cells in the cell banned list to be acceptable cells.

[0368] Embodiment 7: The core network sends the first configuration information, and the UAV UE performs cell selection and reselection according to the first configuration information

[0369] Step (a) The UAV UE in the connected state receives the first configuration information sent by the core network through NAS signaling, wherein the first configuration information includes a cell prohibited list and a first frequency list.

[0370] In step (b), the NAS layer of the UAV UE notifies the access stratum (AS) layer of the UAV UE of the first configuration information sent by the core network.

[0371] Step (c) After the UAV UE enters the idle / inactive state, the UAV UE performs cell selection or reselection through the first configuration information.

[0372] In the above-mentioned embodiments 2 to 7, during the process of cell selection or cell reselection, the UAV UE is restricted from selecting or reselecting to the NTZ cell, or the probability of selecting the NTZ cell is reduced, thereby limiting the opportunity for the UAV UE to initiate uplink in the NTZ restricted cell.

[0373] Embodiment 8: Using UAV UE access identification to prevent UAV UE from initiating access in NTZ restricted cells

[0374] Step 1. The RRC layer of the UAV UE receives a specific access identifier configured for the UAV UE indicated by a higher layer. The UAV UE receives a UAC access identifier bar parameter through a system message. For example, the UAC access identifier bar parameter has 8 bits, wherein the rightmost bit or the highest bit corresponds to the access identifier of the UAV UE, and the value is set to 1.

[0375] Step 2: The UAV UE determines that this access is prohibited.

[0376] Embodiment 9: Reducing the access probability of UAV UE in NTZ restricted cells by using UAC access identification bar parameter

[0377] Step (1) The UAV UE receives first configuration information through system information, wherein the first configuration information includes a first UAC prohibition factor.

[0378] Step (2) When the UAV UE performs the access barring check, it generates a random number between 0 and 1. If the random number is less than or equal to the first UAC barring factor, the access is allowed and the terminal initiates the access. In order to prevent the UAV UE from accessing the NTZ restricted cell as much as possible, the network side device will configure a very low first UAC barring factor, for example, the first UAC barring factor is equal to 0.

[0379] It should be noted that in the above-mentioned embodiments 8 to 9, the UAC mechanism is used to achieve the effect that the UAV UE can reside in the NTZ restricted cell, but is restricted from initiating uplink.

[0380] Embodiment 10: Notifying an idle or inactive UAV UE that it has entered or is about to enter a NTZ coverage cell

[0381] Step 1) The UAV UE receives second configuration information, where the second configuration information includes first reference location information and a first distance threshold.

[0382] Step 2) The distance between the current geographical location of the UAV UE and the first reference location is less than or equal to a third distance threshold, and the UAV UE performs at least one of the following operations:

[0383] Triggering cell reselection, i.e. reselecting to a frequency band or cell that is not NTZ restricted;

[0384] It is forbidden to stay in the current serving cell, that is, the serving cell is considered barred;

[0385] Prohibit access in the current serving cell, i.e., consider that the serving cell does not allow access, for example, accessattempt is considered barred;

[0386] Determine that the current serving cell is an acceptable cell.

[0387] It should be noted that this embodiment can be directed to an ilde or inactive UAV UE in a cell located at the edge of the NTZ (only part of the area is covered by the NTZ). When the UAV UE in the cell is about to fly into the NTZ area, the UAV UE can judge through the cell broadcast information that it is about to enter the NTZ area. Optionally, the UAV UE can trigger the cell to reselect to a non-NTZ restricted frequency band or cell, or when the UAV UE enters the NTZ area, the terminal can reside in the current serving cell, but does not initiate a connection.

[0388] Example 11: For a connected UAV UE, when the UAV UE enters or is about to enter the NTZ coverage area, a measurement report is triggered

[0389] Step a: The UAV UE receives second configuration information, wherein the second configuration information includes configuration related to the first event and an absolute altitude value.

[0390] Step b: The UAV UE meets the first event entry condition and the first time delay TTT, and the height of the UAV UE is greater than the absolute height value, triggering a measurement report.

[0391] Step c: The UAV UE receives a source serving cell switching command, and the UAV UE performs cell switching and forwards data to a target cell, wherein the target cell is a cell not restricted by the NTZ.

[0392] Optionally, the measurement report of the UAV UE may instruct the network-side device to allocate uplink resources and the specific size of the resources for the connected UAV UE.

[0393] Optionally, when the UAV UE meets the first event or the second event condition, the UAV UE may trigger one of a measurement report and a notification to the MAC layer to trigger a BSR report.

[0394] It should be noted that this embodiment can be aimed at a UAV UE in a connected state in a cell located at the edge of the NTZ (only a partial area is covered by the NTZ). When the UAV UE in the cell is about to fly into the NTZ area, according to the corresponding second configuration information, the UAV UE can trigger a measurement report to inform the network side device that it is about to enter the NTZ area. The network can switch the UAV UE to a non-NTZ restricted frequency band or cell, or the UAV UE informs the network side device that it is about to enter the NTZ area and requests the network side device to configure more uplink resources so that the UAV UE can quickly send the uplink data before flying into the NTZ area.
