[0071] The cell information indication method, device, terminal and network side device provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings and some embodiments and application scenarios thereof.

[0072] Please refer to FIG. 2, which is a flowchart of a cell information indication method provided by the embodiments of the present application, as shown in FIG. 2, including the following steps:

[0073] Step 201: The first terminal receives first information of a first cell sent by a network side device, and the first information is used to indicate at least one of the following:

[0074] The cell type of the first cell, the first cell prohibiting terminals satisfying a first condition from accessing, and the first cell allowing terminals satisfying a second condition to access.

[0075] The cell type includes a low-altitude cell or a non-low-altitude cell.

[0076] The low-altitude cell can be a low-altitude cell defined in a protocol, or the low-altitude cell can be a cell with a service height in a specific height range, such as a cell with a service height of 50 meters to 600 meters as a low-altitude cell, or a cell serving 50 meters or more as a low-altitude cell, or the low-altitude cell can be a low-altitude economic private network, such as a low-altitude economic private network constructed by a dedicated frequency or optimized by an upper side lobe of a base station antenna beam or adjusted by a downtilt angle to meet the coverage of low altitude, such as a low-altitude economic private network specially optimized for the network covering the UAV terminal flight area to ensure the experience and service quality of the UAV terminal communication and sensing service during the UAV terminal flight. When the UAV terminal or the terminal with low-altitude cell capability is in flight and / or low-altitude height, the priority of the low-altitude cell is higher than that of other cells when the UAV terminal or the terminal with low-altitude cell capability performs cell reselection.

[0077] In the embodiments of the present application, the low-altitude cell can also be referred to as a low-altitude coverage cell.

[0078] The non-low-altitude cell can be a ground cell or a cell other than the low-altitude cell.

[0079] For example, as shown in FIG. 3, including a low-altitude cell and a ground cell, the UAV terminal does not enter the ground cell in the flight state.

[0080] In some embodiments, the first cell is a serving cell or another cell of the first terminal.

[0081] The first condition includes at least one of the following:

[0082] The position of the terminal is in a first position area, the height of the terminal is in a first height interval, the flight state of the terminal is in a first state, the terminal is a first type of terminal, the moving speed of the terminal is in a first speed interval, the uplink interference size is in a first range, the signal strength detected by the terminal is in a first strength interval, and the number of LOS cells detected by the terminal is in a first number range.

[0083] The uplink interference size is an uplink interference size indicated by the network side device to the terminal.

[0084] The first condition can be a protocol agreement or a network side device configuration. For example, the first terminal has obtained the first condition before receiving the first information, or the first condition is indicated in the first information.

[0085] The first position area, the first height interval, the first state, the first type of terminal, the first speed interval, the first range, the first strength interval, and the first number range can be a protocol agreement or a network side device configuration.

[0086] The position of the terminal can be an absolute position, a relative position, three-dimensional (3D) position information, or position change information.

[0087] The position of the terminal in the first position area indicates that the first cell prohibits terminals in the first position area from accessing. The specific position of the first position area can be flexibly set according to actual conditions, and embodiments of the present application do not limit this.

[0088] The height of the terminal can be a relative height, an absolute height, or height change information.

[0089] The height of the terminal in the first height interval indicates that the first cell prohibits terminals in the first height interval from accessing. The specific value of the first height interval can be flexibly set according to actual conditions, and embodiments of the present application do not limit this. For example, in the case of the first cell being a non-low-altitude cell, the first height interval can be a height greater than 50 meters or 100 meters. For another example, in the case of the first cell being a low-altitude cell, the first height interval can be a height less than 50 meters or 100 meters.

[0090] The flight state of the terminal includes at least one of non-flight (or referred to as flight off, such as turning off the flight device, such as turning off the propeller, etc.), takeoff, flight, and landing.

[0091] The first state can be a state agreed by a protocol or configured by a network side device, and the flight state of the terminal being in the first state indicates that the first cell prohibits the terminal in the first state from accessing, for example, in a case where the first cell is a low-altitude cell, the first state can be a state of closing flight (for example, closing flight equipment such as a propeller), taking off or landing, and for another example, in a case where the first cell is a non-low-altitude cell, the first state can be a state of flying, taking off or landing.

[0092] The first type of terminal can be a UAV terminal and a non-UAV terminal, and the terminal type can be used to distinguish the UAV terminal and the non-UAV terminal according to terminal type information and terminal capability information of the terminal.

[0093] The terminal being the first type of terminal indicates that the first cell prohibits the first type of terminal from accessing, for example, in a case where the first cell is a low-altitude cell, the first type of terminal is a non-UAV terminal, and for another example, in a case where the first cell is a non-low-altitude cell, the first type of terminal is a UAV terminal.

[0094] The speed of the terminal can be obtained by the terminal according to an inertial measurement unit, a speedometer or other devices, or the speed of the terminal can be measured by a network side device and notified to the terminal, or the terminal can obtain the speed of the terminal by detecting a sensing signal / integrated sensing signal such as a downlink sensing signal sent by a base station.

[0095] The first speed range can be agreed by a protocol or configured by a network side device, and the speed of the terminal being in the first speed range indicates that the first cell prohibits the terminal with the first speed from accessing, for example, in a case where the first cell is a non-low-altitude cell, the first speed is a speed range greater than 10Km / h or 15Km / h, and for another example, in a case where the first cell is a low-altitude cell, the first speed is a speed range less than 10Km / h or 15Km / h.

[0096] The uplink interference of the terminal can be uplink co-frequency interference, such as uplink interference of a serving cell caused by a neighbor cell.

[0097] In some embodiments, the uplink interference of the terminal can be an uplink interference detected by a network side device, such as an uplink interference measured by a network side device of a serving cell and notified to the terminal.

[0098] The first range can be agreed by a protocol or configured by a network side device, and different first ranges can be agreed or configured for low-altitude cells and non-low-altitude cells.

[0099] The signal strength detected by the terminal can be a reference signal received power (RSRP), the first strength interval can be a signal strength size interval, or can be a number of neighboring cells in which the signal strength is located in a target signal strength interval, such as a number of neighboring cells in which the detected signal strength is located in a target signal strength interval being X or less than or equal to X, X being a positive integer, and the value of X being different for low-altitude cells and non-low-altitude cells.

[0100] The signal strength detected by the terminal being located in the first strength interval indicates that the first cell prohibits access by the terminal that does not detect the first strength interval.

[0101] The LOS cell can be a LOS cell detected by the terminal, where the LOS cell is a cell that satisfies a LOS condition, such as a cell in which there is a LOS path between the terminal and a network-side device of the cell.

[0102] The first number range can be agreed upon by a protocol or configured by a network-side device, and the value of the first number is different for low-altitude cells and non-low-altitude cells.

[0103] The number of LOS cells detected by the terminal being located in the first number range indicates that the first cell prohibits access by the terminal in which the number of detected LOS cells is located in the first number range, such as a terminal in which the number of prohibited detected LOS cells is greater than 2 or 3 in the case of the first cell being a low-altitude cell, or a terminal in which the number of prohibited detected LOS cells is less than 2 or 3 in the case of the first cell being a non-low-altitude cell.

[0104] In some embodiments, the first cell prohibiting access by the terminal that satisfies the first condition can also be understood as the first cell allowing access by the terminal that does not satisfy the first condition.

[0105] The second condition includes at least one of the following:

[0106] The position of the terminal is located in a second position area, the height of the terminal is located in a second height interval, the flight state of the terminal is in a second state, the terminal is a second type of terminal, the moving speed of the terminal is located in a second speed interval, the uplink interference is located in a second range, the signal strength detected by the terminal is located in a second strength interval, and the number of LOS cells detected by the terminal is located in a second number range.

[0107] The second condition can be agreed upon by a protocol or configured by a network-side device, such as the first terminal having obtained the second condition before receiving the first information, or the second condition being indicated in the first information.

[0108] The second location area, the second height interval, the second state, the second type of terminal, the second speed interval, the second range, the second intensity interval, and the second number range can be protocol agreed or configured by the network side device,

[0109] The second location area is different from the first location area, the second height interval is different from the first height interval, the second state is different from the first state, the second type of terminal is the same as the first type of terminal, the second speed interval is different from the first speed interval, the second range is different from the first range, the second intensity interval is different from the first intensity interval, and the second number range is different from the first number range.

[0110] The position of the terminal is located in the second location area, which indicates that the first cell allows the terminal in the second location area to access. The specific position of the second location area can be flexibly set according to actual conditions, and embodiments of the present application do not limit this.

[0111] The height of the terminal is located in the second height interval, which indicates that the first cell allows the terminal in the second height interval to access. The specific interval of the second height interval can be flexibly set according to actual conditions, and embodiments of the present application do not limit this. For example, in the case that the first cell is a non-low-altitude cell, the second height interval can be a height less than 50 meters or 100 meters. For another example, in the case that the first cell is a low-altitude cell, the second height interval can be a height greater than 50 meters or 100 meters.

[0112] The second state can be a state agreed by a protocol or configured by a network side device. The flight state of the terminal is in the second state, which indicates that the first cell allows the terminal in the second state to access. For example, in the case that the first cell is a non-low-altitude cell, the second state can be a state of closing flight, taking off, or landing. For another example, in the case that the first cell is a low-altitude cell, the second state can be a state of flying, taking off, or landing.

[0113] The second type of terminal can be a UAV terminal and a non-UAV terminal.

[0114] The terminal being the second type of terminal indicates that the first cell allows the second type of terminal to access. For example, in the case that the first cell is a low-altitude cell, the second type of terminal is a UAV terminal. For another example, in the case that the first cell is a non-low-altitude cell, the second type of terminal is a non-UAV terminal.

[0115] The second speed interval can be agreed by a protocol or configured by a network-side device, and the second speed can be a speed interval. The moving speed of the terminal being in the second speed interval indicates that the terminal is allowed to access the first cell. For example, when the first cell is a low-altitude cell, the second speed interval is a speed interval greater than 10Km / h or 15Km / h. For another example, when the first cell is a non-low-altitude cell, the second speed interval is a speed interval less than 10Km / h or 15Km / h.

[0116] The second range can be agreed by a protocol or configured by a network-side device, and different ranges can be agreed or configured for low-altitude cells and non-low-altitude cells.

[0117] The signal strength detected by the terminal being in the second strength interval indicates that the terminal is allowed to access the first cell.

[0118] The second number range can be agreed by a protocol or configured by a network-side device, and the second number range has different values for low-altitude cells and non-low-altitude cells.

[0119] The number of LOS cells detected by the terminal being in the second number range indicates that the terminal is allowed to access the first cell. For example, when the first cell is a non-low-altitude cell, the terminal is allowed to access the first cell if the number of detected LOS cells is greater than 2 or 3. For another example, when the first cell is a low-altitude cell, the terminal is allowed to access the first cell if the number of detected LOS cells is less than 2 or 3.

[0120] In some embodiments, the first cell allowing the terminal to access when the second condition is met can also be understood as the first cell prohibiting the terminal from accessing when the second condition is not met.

[0121] In some embodiments, the first information can indicate the at least one item in an explicit or implicit manner. For example, a network-side device indicates whether the first cell is a low-altitude cell by 1 bit in a system information block (SIB), and the first information includes the SIB. For another example, the network-side device sends information about a height interval or a moving speed interval corresponding to a low-altitude height or a terminal flight state in the first cell, and the first information includes the information about the height interval or the moving speed interval. For another example, the network-side device indicates that the first cell prohibits the terminal from accessing when the first condition is met or that the first cell allows the terminal to access when the second condition is met by 1 bit in a SIB.

[0122] In some embodiments, the first information can be any one of only indicating the cell type of the first cell, the first cell prohibiting the terminal satisfying the first condition to access, and the first cell allowing the terminal satisfying the second condition to access, or the first information can be multiple ones of indicating the cell type of the first cell, the first cell prohibiting the terminal satisfying the first condition to access, and the first cell allowing the terminal satisfying the second condition to access, and in the case of indicating multiple ones, the first information can include one or more signaling or messages, i.e., in the case of indicating multiple ones, the indication can be performed through one or more signaling or messages.

[0123] The first information can be transmitted through a broadcast message, and in some embodiments, can also be transmitted through a terminal-specific message.

[0124] In some embodiments, the first terminal is a UAV terminal or a terminal with low-altitude cell capability. The terminal with low-altitude cell capability can be a terminal capable of communicating in a low-altitude cell, and the terminal with low-altitude cell capability can also be referred to as a terminal with low-altitude capability.

[0125] In the embodiments of the present application, the first information can be obtained before the terminal accesses the cell through the above steps. The cell type can enable the terminal to select a cell of a corresponding type to access, so as to improve the service experience of the terminal. The first cell prohibiting the terminal satisfying the first condition to access can avoid the terminal initiating access to the cell that prohibits access, so that the terminal accesses a suitable cell, thereby improving the service experience of the terminal. The first cell allowing the terminal satisfying the second condition to access can enable the terminal to access the cell only when allowed, so as to improve the service experience of the terminal. For example, a UAV terminal accesses a non-low-altitude cell during a flight phase or a take-off phase, so as to avoid the UAV terminal frequently switching between a ground cell and a low-altitude cell, thereby improving the service experience of the UAV terminal.

[0126] In addition, the cell type of the first cell, the first cell prohibiting the terminal satisfying the first condition to access, and the first cell allowing the terminal satisfying the second condition are all conducive to reducing the risk of cell overload.

[0127] As an optional embodiment, the method further includes at least one of the following:

[0128] The first terminal determines the priority of the first cell according to the first feature information of the first terminal and the cell type of the first cell.

[0129] The first terminal determines whether the first condition is satisfied according to the first feature information of the first terminal.

[0130] The first terminal determines whether the second condition is met according to first characteristic information of the first terminal.

[0131] The first characteristic information of the first terminal includes at least one of the following:

[0132] The flight state of the first terminal, the height information of the first terminal, the position of the first terminal, the type of the first terminal, the moving speed of the first terminal, the uplink interference size indicated by the network-side device to the first terminal, the signal strength information detected by the first terminal, and the information of the LOS cell detected by the first terminal.

[0133] The first characteristic information can be current first characteristic information of the terminal, or first characteristic information of a target time period. The target time period can be a latest time window when the terminal determines the target parameter configuration. The first characteristic information of the terminal in the target time period can be an average of the first characteristic information of the terminal at multiple time points in the target time period, or multiple first characteristic information of the terminal at multiple time points in the target time period, or overall first characteristic information of the terminal in the target time period, such as when the terminal is located in the height interval in the target time period.

[0134] Since the first characteristic information of the first terminal can be first characteristic information of the first terminal in a target time period, the first characteristic information of the terminal can be obtained by multiple time sampling or time domain filtering to reduce the ping-pong effect and improve the reliability of the characteristic information.

[0135] The current first characteristic information can refer to the first characteristic information of the terminal when determining the priority of the first cell or determining whether the first condition or the second condition is met, such as the speed, position, height, and other characteristic information of the terminal when determining the priority of the first cell or determining whether the first condition or the second condition is met.

[0136] In some embodiments, the height information is determined based on at least one of the following:

[0137] The downlink positioning signal, the reference signal, the sensing signal, the integrated sensing signal, the global navigation satellite system (GNSS), the altimeter, and the sensor.

[0138] In this embodiment, the first terminal can determine the height information of the first terminal according to the detection of the downlink positioning signal, the reference signal, the sensing signal, and the integrated sensing signal, or determine the height information of the first terminal according to the GNSS module, or determine the height information of the first terminal according to the altimeter or other sensors.

[0139] The flight state can be at least one of non-flight (e.g., the flight device such as a propeller is turned off), take-off, flight, and landing.

[0140] In some embodiments, the flight state is determined based on a moving speed of the first terminal, and in a case where the moving speed of the first terminal is in a fifth speed interval, the flight state indicates flight.

[0141] The fifth speed interval can be agreed by a protocol or configured by a network side device, for example, a speed interval greater than 10Km / h or 15Km / h.

[0142] In some embodiments, the flight state can also be determined based on a state of a flight device (e.g., a propeller) of the first terminal, for example, in a case where a rotating speed of the propeller is higher than a specific rotating speed, the flight state is flight.

[0143] The first terminal determines the priority of the first cell according to the first characteristic information of the first terminal and a cell type of the first cell, which can be that in a case where the first characteristic information matches the cell type of the first cell, the priority of the first cell is determined as a highest priority, and in a case where the first characteristic information does not match the cell type of the first cell, the priority of the first cell is determined as a lowest priority, for details, refer to the following embodiments.

[0144] In some embodiments, the priority is used for cell reselection.

[0145] Since the first terminal determines the priority of the first cell according to the first characteristic information of the first terminal and the cell type of the first cell, the determined priority of the first cell matches the characteristic information of the terminal, thereby improving the effect of cell reselection.

[0146] The first terminal determines whether the first condition is met according to the first characteristic information of the first terminal, which can be that whether the first characteristic information is in a corresponding area, interval or range of the first condition, and if yes, the first condition is met, thereby prohibiting access to the first cell, thereby avoiding the terminal to access an unsuitable cell, for example, avoiding the UAV terminal in flight to access a non-low-altitude cell.

[0147] The first terminal determines whether the second condition is met according to the first characteristic information of the first terminal, which can be that whether the first characteristic information is in a corresponding area, interval or range of the second condition, and if yes, the second condition is met, thereby allowing access to the first cell, thereby allowing the terminal to access a suitable cell, for example, allowing the UAV terminal in flight to access a low-altitude cell.

[0148] In some embodiments, the determination of the priority of the first cell includes at least one of the following:

[0149] determining the priority of the first cell as the highest priority in a case that the flight status of the first terminal is flying and the cell type of the first cell is a low-altitude cell;

[0150] determining the priority of the first cell as the highest priority in a case that the height information of the first terminal indicates that the first terminal is in a low-altitude position and the cell type of the first cell is a low-altitude cell;

[0151] determining the priority of the first cell as the highest priority in a case that the flight status of the first terminal is flying, the height information of the first terminal indicates that the first terminal is in a low-altitude position, and the cell type of the first cell is a low-altitude cell;

[0152] determining the priority of the first cell as the lowest priority in a case that the flight status of the first terminal is not flying and the cell type of the first cell is a low-altitude cell;

[0153] determining the priority of the first cell as the lowest priority in a case that the height information of the first terminal indicates that the first terminal is not in a low-altitude position and the cell type of the first cell is a low-altitude cell.

[0154] wherein at least one of the fifth speed interval corresponding to the flight status of flying and the height interval corresponding to the low-altitude position is agreed by protocol or configured by a network-side device. The fifth speed interval corresponding to the flight status of flying can be understood as that the flight status of the terminal is flying when the speed is in the fifth speed interval, and the height interval corresponding to the low-altitude position can be understood as that the terminal is in a low-altitude position when the height of the terminal is in the height interval.

[0155] For example, the protocol defines or the network-side device notifies the terminal through broadcast signaling that the height interval corresponding to the low-altitude position is 50 meters to 600 meters or 50 meters or more; for another example, the protocol defines or the network-side device notifies the terminal through broadcast signaling that the fifth speed interval corresponding to the flight status of flying is greater than 10 Km / h or 20 Km / h, and the state of the moving speed being greater than 10 Km / h or 20 Km / h and the height of the terminal being 50 meters to 600 meters or 50 meters or more is the flight status.

[0156] The height information of the first terminal indicating that the first terminal is in a low-altitude can be understood as being in a low-altitude height or a low-altitude position.

[0157] The highest priority can be understood as that the priority of the first cell is higher than the priority of any other cell, for example, when the UAV terminal or the terminal supporting the low-altitude cell is in the flight status and / or the low-altitude height, the low-altitude cell is always considered as the highest priority.

[0158] The above lowest priority can be understood as that the priority of the first cell is lower than the priority of any other cell, such as when the UAV terminal or the terminal supporting the low-altitude cell is not in the flight state and / or not at the low-altitude height, the low-altitude cell is always considered as the lowest priority.

[0159] By determining the priority of the first cell, when the UAV terminal or the terminal supporting the low-altitude cell is in the flight state and / or at the low-altitude height, the low-altitude cell is considered as the highest priority, which increases the probability of the UAV terminal or the terminal supporting the low-altitude cell accessing the low-altitude cell, and meets the user experience (such as communication and perception user experience) of the UAV terminal or the terminal supporting the low-altitude cell. When the UAV terminal or the terminal supporting the low-altitude cell is not in the flight state and / or not at the low-altitude height, the low-altitude cell is considered as the lowest priority, at this time, the UAV terminal or the terminal supporting the low-altitude cell which is not in the flight state and / or not at the low-altitude height will have a high probability of accessing the non-low-altitude cell, which reduces the probability of the UAV terminal or the terminal supporting the low-altitude cell accessing the low-altitude cell which is not in the flight state and / or not at the low-altitude height, and reduces the risk of overloading of the low-altitude cell.

[0160] For example, in an embodiment, the network side device indicates whether the first cell is a low-altitude cell through a broadcast message, specifically as follows:

[0161] The network side device base station indicates whether the first cell is a low-altitude cell through a broadcast message, such as indicating whether the cell is a low-altitude cell through 1 bit in the SIB;

[0162] The terminal reads the broadcast message;

[0163] When the UAV terminal or the terminal supporting the low-altitude cell is in flight and / or at the low-altitude height, the terminal always considers the low-altitude cell as the highest priority (i.e. higher than the priority of any other cell). When the UAV terminal or the terminal supporting the low-altitude cell is not in the flight state and / or at the low-altitude height, the terminal always considers the low-altitude cell as the lowest priority.

[0164] The above priority is used for cell reselection, and the cell reselection mechanism based on the priority can refer to the relevant provisions of the protocol, and the embodiments of the present application will not be described in detail. The embodiments of the present application can be applied to the same or similar cell reselection mechanism.

[0165] The terminal determines that it is at the low-altitude height / low-altitude position by determining that it is at the low-altitude height / low-altitude position.

[0166] The terminal determines its position related information according to the detection of the downlink positioning signal or other reference signals / perception signals / communication and perception integrated signals;

[0167] The terminal determines its position related information according to the GNSS module.

[0168] The terminal determines its height information according to a height meter or other sensors;

[0169] The method for the terminal to determine that it is in the flight state can be that the moving speed of the terminal is in a target interval, for example, the moving speed of the terminal is greater than 10 Km / h; the terminal can obtain the moving speed and other related information according to an inertial measurement unit, a speedometer, or other devices, or the network side device measures the moving speed of the terminal and notifies the terminal of the moving speed;

[0170] The height interval / moving speed interval corresponding to the low-altitude height / flight state is defined by a protocol or notified to the terminal by the network side device through broadcast signaling; for example, the protocol or the network side device notifies the terminal through broadcast signaling that the low-altitude height is 50 meters to 600 meters or above 50 meters; the protocol or the network side device notifies the terminal through broadcast signaling that the moving speed greater than 10 Km / h or 20 Km / h is flight, and the moving speed greater than 10 Km / h or 20 Km / h and the height of the terminal being 50 meters to 600 meters or above 50 meters is flight;

[0171] In some embodiments, in the signaling design, the cell broadcasting the height interval / moving speed interval is the low-altitude cell, that is, there is no need for an additional 1 bit SIB to indicate whether the cell is a low-altitude cell.

[0172] In this embodiment, the network side device indicates whether the cell is a low-altitude cell through a broadcast message, when the UAV terminal or the terminal with low-altitude cell capability is in the flight state and / or at the low-altitude height, the low-altitude cell is always considered as the highest priority (i.e., higher than the priority of any other cell), which increases the probability of the UAV terminal or the terminal with low-altitude cell capability accessing the low-altitude cell, and meets the user experience of the UAV terminal or the terminal with low-altitude cell capability. When the UAV terminal or the terminal with low-altitude cell capability is not in the flight state and / or not at the low-altitude height, the low-altitude cell is always considered as the lowest priority (i.e., lower than the priority of any other cell), at this time, the UAV terminal or the terminal with low-altitude cell capability accesses to a suitable cell, for example, the UAV terminal or the terminal with low-altitude cell capability will access the non-low-altitude cell with high probability, to improve the service experience of the UAV terminal or the terminal with low-altitude cell capability which is not in the flight state and / or not at the low-altitude height, and also to reduce the probability of the UAV terminal or the terminal with low-altitude cell capability accessing the low-altitude cell which is not in the flight state and / or not at the low-altitude height, and reduce the risk of overloading of the low-altitude cell.

[0173] In some embodiments, the determining the priority of the first cell comprises at least one of:

[0174] In a case that the first terminal is located in a third location area and the first cell is a low-altitude cell, the priority of the first cell is determined as the highest priority;

[0175] In a case that the first terminal is located in a fourth location area and the first cell is a low-altitude cell, the priority of the first cell is determined as the lowest priority.

[0176] The third location area and the second location area can be the same, the fourth location area and the first location area can be the same, or the third location area and the fourth location area are completely different from the first location area and the second location area, which can be set according to actual needs.

[0177] In this embodiment, the low-altitude cell priority can be determined as the highest priority for the terminal in the third location area, and the low-altitude cell priority can be determined as the lowest priority for the terminal in the fourth location area, so that the terminal accesses to a suitable cell, and the service experience of the terminal is improved.

[0186] The third speed interval can be the same as the second speed interval, the fourth speed interval can be the same as the first speed interval, or the third and fourth speed intervals can be completely different from the first and second speed intervals, which can be set according to actual needs.

[0187] In this embodiment, the low-altitude cell priority can be determined as the highest priority for the terminal in the third speed interval, and the low-altitude cell priority can be determined as the lowest priority for the terminal in the fourth speed interval, so that the terminal accesses to a suitable cell, and the service experience of the terminal is improved.

[0188] In some embodiments, the determination of the priority of the first cell includes at least one of the following:

[0189] In a case that the uplink interference size indicated by the network-side device to the first terminal is in a third range and the cell type of the first cell is a low-altitude cell, the priority of the first cell is determined as a highest priority;

[0190] In a case that the uplink interference size indicated by the network-side device to the first terminal is in a fourth range and the cell type of the first cell is a low-altitude cell, the priority of the first cell is determined as a lowest priority.

[0191] The third range can be the same as the second range, the fourth range can be the same as the first range, or the third and fourth ranges can be completely different from the first and second ranges, which can be set according to actual needs.

[0192] In this embodiment, the low-altitude cell priority can be determined as the highest priority for the terminal in the third range of uplink interference size, and the low-altitude cell priority can be determined as the lowest priority for the terminal in the fourth range of uplink interference size, so that the terminal accesses to a suitable cell, and the service experience of the terminal is improved.

[0193] In some embodiments, the determination of the priority of the first cell includes at least one of the following:

[0194] In a case where the signal strength indicated by the signal strength information detected by the first terminal is in a third strength interval and the cell type of the first cell is a low-altitude cell, the priority of the first cell is determined as a highest priority;

[0195] In a case where the signal strength indicated by the signal strength information detected by the first terminal is in a fourth strength interval and the cell type of the first cell is a low-altitude cell, the priority of the first cell is determined as a lowest priority.

[0196] The third strength interval and the second strength interval can be the same, the fourth strength interval and the first strength interval can be the same, or the third strength interval and the fourth strength interval are completely different from the first strength interval and the second strength interval, which can be set according to actual needs.

[0197] In this embodiment, the low-altitude cell priority can be determined as the highest priority for the terminal whose detected signal strength is in the third strength interval, and the low-altitude cell priority can be determined as the lowest priority for the terminal whose detected signal strength is in the fourth strength interval, so that the terminal accesses to a suitable cell, and the service experience of the terminal is improved.

[0198] In some embodiments, the determining the priority of the first cell comprises at least one of:

[0199] In a case where the number of LOS cells indicated by the LOS cell information detected by the first terminal is in a third number range and the cell type of the first cell is a low-altitude cell, the priority of the first cell is determined as a highest priority;

[0200] In a case where the number of LOS cells indicated by the LOS cell information detected by the first terminal is in a fourth number range and the cell type of the first cell is a low-altitude cell, the priority of the first cell is determined as a lowest priority.

[0201] The third number range and the second number range can be the same, the fourth number range and the first number range can be the same, or the third number range and the fourth number range are completely different from the first number range and the second number range, which can be set according to actual needs.

[0202] In this embodiment, the low-altitude cell priority can be determined as the highest priority for the terminal whose detected number of LOS cells is in the third number range, and the low-altitude cell priority can be determined as the lowest priority for the terminal whose detected number of LOS cells is in the fourth number range, so that the terminal accesses to a suitable cell, and the service experience of the terminal is improved.

[0203] It should be noted that in the embodiments of the present application, the priority of the first cell is not limited in the case that the first cell is a non-low-altitude cell, for example:

[0204] In the case that the flight state of the first terminal is flying and the cell type of the first cell is a non-low-altitude cell, the priority of the first cell is determined as the lowest priority;

[0205] In the case that the height information of the first terminal indicates that the first terminal is in a low-altitude position and the cell type of the first cell is a non-low-altitude cell, the priority of the first cell is determined as the lowest priority;

[0206] In the case that the flight state of the first terminal is flying, the height information of the first terminal indicates that the first terminal is in a low-altitude position, and the cell type of the first cell is a non-low-altitude cell, the first cell is regarded as a cell with the lowest priority.

[0207] As an optional implementation, the method further includes at least one of the following:

[0208] In the case that the first terminal meets the second condition, accessing or camping to the first cell;

[0209] In the case that the first terminal does not meet the first condition, accessing or camping to the first cell;

[0210] In the case that the first terminal meets the first condition, not accessing or camping to the first cell;

[0211] In the case that the first terminal does not meet the second condition, not accessing or camping to the first cell.

[0212] The meeting or not meeting the first condition or the second condition can be determined based on the first feature information described in the above implementation.

[0213] In this implementation, in the case that the first terminal meets the second condition, accessing or camping to the first cell, so that the first cell can be accessed or camped in the allowed case, so as to reduce the risk of overloading of the first cell.

[0214] In this implementation, in the case that the first terminal does not meet the first condition, accessing or camping to the first cell, so that the first cell can be accessed or camped in the case that it is not prohibited to access, so as to reduce the risk of overloading of the first cell.

[0215] In this embodiment, since the first terminal does not access or camp on the first cell when the first condition is met, the first terminal can access or camp on the first cell in the forbidden case, thereby reducing the risk of overloading the first cell.

[0216] In this embodiment, since the first terminal does not access or camp on the first cell when the first condition is met, the first terminal can access or camp on the first cell in the forbidden case, thereby reducing the risk of overloading the first cell.

[0217] In an embodiment, the network side device indicates the target terminal, i.e., the terminal meeting the first condition, to access by broadcasting a message such as SIB1 when the first condition is met.

[0218] The terminal reads the broadcast message.

[0219] If the terminal meets the first condition of the target terminal, the terminal does not access / camp on the first cell

[0220] In some embodiments, the target terminal can meet two or more of the above first conditions, for example, the target terminal needs to meet the UAV terminal and the height is greater than 50 meters; for another example, the target terminal needs to meet the moving speed is greater than 10Km / h and the height is greater than 50 meters.

[0221] In some embodiments, for a low-altitude cell (such as a dedicated network serving UAV terminals), the broadcast message indicates that non-UAV terminals are prohibited from accessing, or terminals with a height lower than 50 meters are prohibited from accessing, or terminals with a moving speed lower than 10Km / h and a height lower than 50 meters are prohibited from accessing;

[0222] In some embodiments, for a non-low-altitude cell (such as a general cell), the broadcast message indicates that UAV terminals are prohibited from accessing, or terminals with a height higher than 50 meters are prohibited from accessing, or terminals with a moving speed greater than 10Km / h and a height greater than 50 meters are prohibited from accessing;

[0223] In some embodiments, the terminal can determine whether it meets the first condition of the target terminal according to the terminal height information in a period of time (equivalent to time domain filtering); for example, the terminal is located in the height interval in the T1 time window, and the corresponding parameter configuration is selected; or the number of samples in which the terminal is located in the relevant height interval exceeds N (M>N, M and N are positive integers) in M samples (M>N, M and N are positive integers), and the corresponding parameter configuration is selected; when the first feature information is location information, moving speed information, detected signal strength information of multiple cells, or other information, it is also applicable. This can sample multiple times in time or filter in time domain, which can reduce the ping-pong effect.

[0224] In this embodiment, the low-altitude cell can indicate, through a broadcast message, that non-UAV terminals are prohibited from accessing, and the non-low-altitude cell (such as a normal cell) can indicate, through a broadcast message, that UAV terminals are prohibited from accessing, so that the low-altitude cell can preferentially serve the UAV terminal and meet the user experience of the UAV terminal, such as improving the communication and perception experience of the UAV terminal.

In this way, the first information can be obtained before the terminal accesses the cell, and the terminal can select a cell of a corresponding type to access through the cell type, so as to improve the service experience of the terminal. In addition, the terminal can avoid initiating access to a cell that prohibits access, so as to improve the service experience of the terminal.
