[0003] In the prior art, the reference point sent by the base station to the terminal is usually a location point located on the surface of the earth or close to the surface of the earth.

[0114] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0115] The terms "first", "second", etc. in the specification and claims of the present invention are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0116] In the NTN network, there is a solution for cell reselection / conditional switching based on location information, as follows:

[0117] Location-based cell reselection:

[0118] The base station sends the reference point and distance threshold to the UE. When the distance between the UE and the reference point is greater than the distance threshold and the serving cell S criterion is not met, the terminal performs neighboring cell measurement.

[0119] Location-based CHO:

[0120] The base station sends the serving cell reference point and distance threshold 1, the neighboring cell reference point and distance threshold 2 to the UE. When the distance between the UE and the serving cell reference point is greater than distance threshold 1, and the distance between the UE and the neighboring cell reference point is less than distance threshold 2, and the serving cell quality does not meet the reference signal receiving power (RSRP) condition configured by the network, the terminal performs conditional switching.

[0121] In the above two schemes, the reference point is usually sent in the format of ellipsoid-point, with a position point on the surface of the earth or close to the surface of the earth as the reference point; or, in the format of ellipsoid-point that varies with height, a reference point located in space is indicated.

[0122] In the prior art, such as Figure 1 and Figure 2 As shown, the position of reference point A generally represents the cell center; while the cell center of a non-ground cell is located above the ground, and the terminal has no fixed height, so there is no fixed cell center. For terminals at different heights, the cell center position is also different.

[0123] If the base station adopts the three-dimensional indication method, it indicates the reference point, such as indicating Figure 1 and Figure 2 If the base station uses a two-dimensional indication method to indicate the reference point, such as Figure 3 As shown, indicating the position of reference point A in the figure, for terminals at different heights, the distance thresholds for cell reselection / conditional switching are different, and the distance threshold needs to consider the height of the terminal to be configured or defined.

[0124] Therefore, based on the above, for non-ground cells, the usual two-dimensional reference points or three-dimensional reference points and the corresponding distance threshold indication method are no longer applicable to terminals with changing heights. If the terminal reports the height information to the base station, and the base station then sends the reference point and distance threshold, the terminal height position will be exposed, which cannot be applied to confidentiality scenarios. At the same time, due to frequent changes in height, frequent signaling interactions and high signaling overhead will occur.

[0125] To solve the above problems, an embodiment of the present invention provides a configuration method, which sends configuration parameters to a terminal through a network device, wherein the configuration parameters include reference point information corresponding to the height range, a distance threshold corresponding to the height range, a height offset granularity, and one or more of the reference point offset granularity, so that the terminal can accurately calculate the reference point and distance threshold corresponding to the current height according to the configuration parameters to adapt to cell reselection and / or conditional switching without a fixed height.

[0126] One embodiment of the present invention provides a configuration method, which is executed by a terminal, such as Figure 4 As shown, the method includes:

[0127] S410: Receive a first message sent by a network device, where the first message includes configuration parameters, and the configuration parameters include one or more of the following:

[0128] Altitude range configuration information, used to indicate different altitude ranges;

[0129] First reference point information corresponding to different height ranges;

[0130] first distance thresholds corresponding to different height ranges;

[0131] a first distance for calculating a second distance threshold;

[0132] Height offset granularity;

[0133] Reference point offset granularity.

[0134] Optionally, in an embodiment of the present invention, the first message received by the terminal may include a system message SIB and / or a radio resource control (RRC) message, that is, the network device sends the first message to the terminal through the SIB and / or RRC message, and the first message includes a configuration parameter. The configuration parameter is used to indicate configuration information of a cell reference point and a distance threshold.

[0135] Using this implementation mode, the configuration parameters in the first message obtained by the terminal indicate the configuration information used to determine the cell reference point and distance threshold. According to the configuration parameters, the terminal can accurately calculate the reference point and distance threshold corresponding to the current height to adapt to cell reselection and / or conditional switching without a fixed height.

[0136] In one implementation manner, optionally, the configuration parameters include altitude range configuration information, where the altitude range configuration information is a common configuration corresponding to different altitudes of the terminal and is used to indicate different altitude ranges.

[0137] Optionally, the altitude range configuration information includes one or more of the following:

[0138] Altitude offset granularity; optionally, the altitude offset granularity is expressed as x, and the unit can be kilometers or meters, etc.;

[0139] Minimum height value; optionally, the minimum height value is expressed in m, and the unit can be kilometers or meters, etc.; wherein, the minimum height value is an optional parameter;

[0140] Altitude range indication value; optionally, the altitude range indication value is represented by n; the altitude range indication value n is a positive integer, and different altitude range indication values ​​n are used to represent different altitude ranges;

[0141] The different height ranges are determined according to the height offset granularity and the different height range indication values; or, the different height ranges are determined according to the height offset granularity, the height minimum value and the different height range indication values.

[0142] According to the height range configuration information in the configuration parameter, when the height range configuration information includes the height offset granularity and the height range indication value n, the height range determined according to different height range indication values ​​n is [n×x, (n+1)×x];

[0143] When the height range configuration information includes the height offset granularity X, the height range indication value n and the height minimum value m, the height range determined according to different height range indication values ​​n and height minimum values ​​is [m+n×x, m+(n+1)×x].

[0144] In an embodiment of the present invention, in one implementation mode, the network device sends configuration parameters in a first message, including the above-mentioned height range configuration information and first reference point information corresponding to different height ranges, each first reference point information corresponds to a height range for indication; optionally, the first reference point information can be one of a three-dimensional position and a two-dimensional position.

[0145] For example, when the altitude range configuration information in the configuration parameters includes the altitude offset granularity (x=1 km) and the altitude range indication value n, the first reference point information in the configuration parameters is respectively:

[0146] Altitude range indicator value n: 3 (representing the altitude range at this time is [3, 4]), first reference point information (X3, Y3, Z3);

[0147] Height range indication n: 4, first reference point information (X4, Y4, Z4);

[0148] Height range indication n: 5, first reference point information (X5, Y5, Z5);

[0149] Height range indication n: 6, first reference point information (X6, Y6, Z6);

[0150] Height range indication n: 7, first reference point information (X7, Y7, Z7);

[0151] Height range indication n: 8, first reference point information (X8, Y8, Z8);

[0152] Height range indication n: 9, first reference point information (X9, Y9, Z9);

[0153] Height range indication n:10, first reference point information (X10, Y10, Z10), etc.

[0154] Therefore, according to the above, each first reference point information corresponds to one of the height ranges indicated by the height range configuration information, and different first reference point information corresponds to different height ranges indicated by the height range configuration information.

[0155] In an embodiment of the present invention, in one implementation mode, the network device sends configuration parameters in a first message, including the above-mentioned height range configuration information and first distance thresholds corresponding to different height ranges, respectively. Optionally, each first distance threshold corresponds to a height range for indication. In addition, each first distance threshold corresponds to a first reference point information.

[0156] For example, when the altitude range configuration information in the configuration parameters includes the altitude offset granularity (X=1 km) and the altitude range indication value n, the first reference point information and the first distance threshold in the configuration parameters are respectively:

[0157] Altitude range indicator value n: 3 (representing the altitude range at this time is [3, 4]), first reference point information (X3, Y3, Z3); first distance threshold DistanceThresh3;

[0158] Height range indication n: 4, first reference point information (X4, Y4, Z4); first distance threshold DistanceThresh4;

[0159] Height range indication n: 5, first reference point information (X5, Y5, Z5); first distance threshold DistanceThresh5;

[0160] Height range indication n: 6, first reference point information (X6, Y6, Z6); first distance threshold DistanceThresh6;

[0161] Height range indication n: 7, first reference point information (X7, Y7, Z7); first distance threshold DistanceThresh7;

[0162] Height range indication n: 8, first reference point information (X8, Y8, Z8); first distance threshold DistanceThresh8;

[0163] Height range indication n: 9, first reference point information (X9, Y9, Z9); first distance threshold DistanceThresh9;

[0164] Height range indication n: 10, first reference point information (X10, Y10, Z10), first distance threshold DistanceThresh10, etc.

[0165] Therefore, according to the above, each of the first distance thresholds corresponds to one of the altitude ranges indicated by the altitude range configuration information, and different first distance thresholds correspond to different altitude ranges indicated by the altitude range configuration information.

[0166] In an embodiment of the present invention, optionally, the first distance threshold is used to indicate the distance threshold between the terminal and the target reference point in the three-dimensional direction when the terminal performs cell reselection and / or switching. Optionally, the target reference point is the position of the reference point corresponding to the target reference point information that needs to be determined when performing cell reselection and / or switching according to the first distance threshold. In one implementation, optionally, the target reference point is used to indicate the center of the cell. The switching includes conditional switching and conditional switching based on position.

[0167] In an embodiment of the present invention, optionally, the configuration parameters in the first message also include second reference point information and / or a third distance threshold, wherein the second reference point information is used to indicate a reference point at a fixed position, and the second reference point information can be three-dimensional coordinate information or two-dimensional coordinate information; the third distance threshold is a fixed distance, used to indicate the distance threshold between the terminal and the reference point in the three-dimensional or two-dimensional direction.

[0168] In another embodiment, optionally, the configuration parameters in the first message include height offset granularity, reference point offset granularity and second reference point information. Based on the height offset granularity, reference point offset granularity and second reference point information, the target reference point information and target distance threshold for performing cell reselection and / or switching can be determined.

[0169] Optionally, in an embodiment of the present invention, the configuration parameters in the first message include a first distance for calculating a second distance threshold, wherein the first distance is used to indicate the distance between the terminal and the target reference point in the horizontal direction, and when the terminal performs cell reselection and / or switching, the first distance is used to calculate the second distance threshold, and the second distance threshold is a distance threshold in the three-dimensional direction between the terminal and the target reference point.

[0170] Optionally, in an embodiment of the present invention, the target reference point is a position of a reference point to which the target reference point information corresponds when cell reselection and / or switching is performed according to the first distance and target reference point information is determined.

[0171] In the embodiment of the present invention, optionally, the first distance threshold includes: a first distance threshold between the terminal and a serving cell; and / or a first distance threshold between the terminal and a neighboring cell;

[0177] Determine target reference point information and target distance threshold according to the configuration parameters;

[0178] Cell reselection and / or handover is performed according to the target reference point information and the target distance threshold.

[0182] Using this implementation mode, when the configuration parameters include the first reference point information and the first distance threshold, the terminal can determine the first reference point information and the first distance threshold of the corresponding height according to the current height, and perform cell reselection and / or conditional switching operations based on the determined first reference point information (target reference point information) and the first distance threshold (target distance threshold) by using the cell reselection and / or conditional switching criteria of the distance.

[0189] With this implementation, when the second reference point information in the configuration parameters is a reference point indicating a fixed position, and a first distance is also indicated in the configuration parameters, the terminal can calculate the deviation height based on the current height of the terminal and the reference point height indicated by the second reference point information, and based on the deviation height and the first distance, the second distance threshold of the terminal relative to the second reference point information can be determined using the Pythagorean theorem, and the second distance threshold is used as the target distance threshold, the second reference point information is used as the target reference point information, and the cell reselection and / or conditional switching criteria based on the distance are used to perform cell reselection and / or conditional switching operations.

[0190] Optionally, the target distance threshold is calculated as follows:

[0191]

[0192] Among them, distanceThresh_UE is the target distance threshold; distanceThresh is the first distance; H is the current height of the terminal; Href is the height information in the second reference point information, that is, it indicates the reference point height; if the second reference point information is a two-dimensional position coordinate, the value of Href is 0.

[0193] In the embodiment of the present invention, optionally, determining the target reference point information and the target distance threshold according to the configuration parameters includes:

[0194] Determine, according to the configuration parameters, first target reference point information corresponding to the serving cell and a first target distance threshold corresponding to the serving cell, and determine second target reference point information corresponding to the adjacent cell and a second target distance threshold corresponding to the adjacent cell;

[0195] The step of performing cell switching according to the target reference point information and the target distance threshold includes:

[0196] Cell switching is performed according to the first target reference point information, the first target distance threshold, the second target reference point information, and the second target distance threshold.

[0197] With this implementation, the target reference point information and the target distance threshold are calculated by respectively calculating the corresponding serving cell to perform cell switching.

[0198] In another implementation of the embodiment of the present invention, when the configuration parameters include the height offset granularity, the reference point offset granularity, the second reference point information and the third distance threshold, determining the target reference point information and the target distance threshold according to the configuration parameters includes:

[0199] Calculating a height offset value of the terminal according to the current height of the terminal and the height information of the second reference point information;

[0200] Calculating third reference point information corresponding to the current height of the terminal according to the height offset value, the height offset granularity, and the reference point offset granularity;

[0201] The third reference point information is determined as the target reference point information, and the third distance threshold is determined as the target distance threshold.

[0202] Using this implementation, Figure 5 As shown, the configuration parameters may include the following information:

[0203] Height offset granularity: x, the unit can be km, m, etc.;

[0204] Reference point offset granularity: such as (ΔX, ΔY) or (Δlongitudinal, Δlatitude);

[0205] Second reference point information: such as represented by (Xref, Yref, Href) or (longitudinal_ref, latitude_ref, altitude_ref); Optionally, the reference point coordinates indicated by the second reference point information are as follows: Figure 5 Reference point A at

[0206] The third distance threshold is used to represent the distance threshold between the terminal and the reference point in the three-dimensional or two-dimensional direction, and is used to indicate the distance condition that needs to be met between the terminal and the reference point in the three-dimensional direction when performing cell reselection and / or switching.

[0207] For example, combining Figure 5 As shown, in one embodiment, the second reference point information (reference point corresponding to position A) is represented by two-dimensional coordinates as (X ref, Y ref); that is, Href is 0;

[0208] Then the terminal can calculate the determined target reference point information (reference point corresponding to position B) and the height offset value corresponding to the second reference point information according to the current height H: ΔH = (H-Href);

[0209] Combination Figure 5As shown, according to the reference point offset granularity (ΔX, ΔY) and the height offset granularity x, the target reference point information (reference point corresponding to position B) is calculated as (X+ΔH / x*ΔX, Y+ΔH / x*ΔY, H); in this way, the determined target reference point information (reference point corresponding to position B) is also the position coordinates of the center of the terminal's current cell.

[0210] On this basis, according to the distance between the current position coordinates of the terminal and the target reference point information, the distance between the current position of the terminal and the reference point corresponding to the target reference point information can be determined. By comparing the determined distance with the first distance threshold indicated by the configuration parameters, it is determined whether the distance-based cell reselection / conditional switching criteria are met to perform the corresponding cell reselection / conditional switching operation.

[0211] In another embodiment, the second reference point information (reference point corresponding to position A) is represented by an ellipse as (longitudinal, latitude); that is, Href is 0;

[0212] Then the terminal can calculate the determined target reference point information (reference point corresponding to position B) and the height offset value corresponding to the second reference point information according to the current height H: ΔH = (H-Href);

[0213] Combination Figure 5 As shown, according to the reference point offset granularity (Δlongidue, Δlatitude) and the height offset granularity x, the target reference point information (reference point corresponding to position B) is calculated as (longidue+ΔH / x*Δlongidue, latitude+ΔH / x*Δlatitude, H)); in this way, the determined target reference point information (reference point corresponding to position B) is also the position coordinates of the center of the current cell of the terminal.

[0214] Similarly, based on the distance between the current position coordinates of the terminal and the target reference point information, the distance between the current position of the terminal and the reference point corresponding to the target reference point information can be determined. By comparing the determined distance with the first distance threshold indicated by the configuration parameters, it is determined whether the distance-based cell reselection / conditional switching criteria are met to perform the corresponding cell reselection / conditional switching operation.

[0215] The configuration method described in the embodiment of the present invention is illustrated below in combination with specific implementation methods.

[0216] Implementation Method 1

[0217] In the first embodiment, the network device sends a first message to the terminal via a SIB message; the configuration parameters of the first message include a height offset granularity, first reference point information corresponding to different height ranges, and first distance thresholds corresponding to different height ranges.

[0218] For example, the height offset granularity is: x = 1km;

[0219] The first reference point information corresponding to different height ranges and the first distance thresholds corresponding to different height ranges are respectively:

[0220] Altitude range indicator value n: 3 (representing the altitude range at this time is [3, 4]), first reference point information (X3, Y3, Z3); first distance threshold DistanceThresh3;

[0221] Height range indication n: 4, first reference point information (X4, Y4, Z4); first distance threshold DistanceThresh4;

[0222] Height range indication n: 5, first reference point information (X5, Y5, Z5); first distance threshold DistanceThresh5;

[0223] Height range indication n: 6, first reference point information (X6, Y6, Z6); first distance threshold DistanceThresh6;

[0224] Height range indication n: 7, first reference point information (X7, Y7, Z7); first distance threshold DistanceThresh7;

[0225] Height range indication n: 8, first reference point information (X8, Y8, Z8); first distance threshold DistanceThresh8;

[0226] Height range indication n: 9, first reference point information (X9, Y9, Z9); first distance threshold DistanceThresh9;

[0227] Height range indication n: 10, first reference point information (X10, Y10, Z10), first distance threshold DistanceThresh10, etc.

[0228] In this implementation, the terminal can determine, based on the current height of the terminal and the height range configuration information, that the first reference point information corresponding to the current height in the first reference point information is the target reference point information, and determine that the first distance threshold corresponding to the current height in the first distance threshold is the target distance threshold, and perform cell reselection and / or switching based on the target reference point information and the target distance threshold.

[0229] For example, combining Figure 6 As shown, the current height of the terminal is 7.5 km. According to the current height of 7.5 km, the corresponding first reference point information (X7, Y7, Z7) is selected. The first reference point information (X7, Y7, Z7) is also the reference point position of the cell corresponding to the current height. Figure 6 The reference point position A shown in the figure, in addition, according to the current height of 7.5km, the corresponding first distance threshold DistanceThresh7 is selected. In this way, the terminal can determine the distance D1 of the current position compared to the reference point position A corresponding to the first reference point information according to the coordinates of the current position and the coordinates of the determined first reference point information (X7, Y7, Z7), and compare the distance D1 with the determined first distance threshold DistanceThresh7, and perform the corresponding cell reselection operation according to the comparison result and the cell reselection criterion based on the distance.

[0230] Implementation Method 2

[0231] In the second implementation mode, the network device sends a first message to the terminal via a SIB message; the configuration parameters of the first message include a height offset granularity, first reference point information corresponding to different height ranges, a minimum height value, and a third distance threshold.

[0232] For example, the height offset granularity and the minimum height value are:

[0233] Height offset granularity: 1km;

[0234] Minimum altitude: 3km.

[0235] Optionally, the third distance threshold is expressed as DistanceThresh.

[0236] The first reference point information corresponding to different height ranges are respectively expressed as:

[0237] Altitude range indication: 0 (representing the altitude range at this time is [3, 4]), first reference point information (X0, Y0, Z0)

[0238] Altitude range indication: 1, first reference point information (X1, Y1, Z1);

[0239] Altitude range indication: 2, first reference point information (X2, Y2, Z2);

[0240] Altitude range indication: 3, first reference point information (X3, Y3, Z3);

[0241] Altitude range indication: 4, first reference point information (X4, Y4, Z4);

[0242] Altitude range indication: 5, first reference point information (X5, Y5, Z5);

[0243] Altitude range indication: 6, first reference point information (X6, Y6, Z6);

[0244] Altitude range indication: 7, first reference point information (X7, Y7, Z7).

[0245] In this implementation, the terminal can determine, based on the current height of the terminal and the height range configuration information, that the first reference point information corresponding to the current height in the first reference point information is the target reference point information, and determine that the third distance threshold is the target distance threshold, and perform cell reselection and / or switching based on the target reference point information and the target distance threshold.

[0246] For example, combining Figure 7 As shown, the current height of the terminal is 4.3 km. According to the current height of 4.3 km, the corresponding first reference point information (X1, Y1, Z1) is selected. The first reference point information (X1, Y1, Z1) is also the reference point position of the cell corresponding to the current height. Figure 7 Reference point position A is shown.

[0247] In this way, the terminal can determine the distance of the current position compared to the reference point position A corresponding to the first reference point information based on the current position coordinates and the coordinates of the determined first reference point information (X1, Y1, Z1), and compare the distance with the third distance threshold (such as expressed as D) indicated by the configuration parameters. According to the comparison result, the terminal performs the corresponding cell reselection operation based on the distance-based cell reselection criteria.

[0248] Implementation Method 3

[0249] In this implementation, the network device sends a first message to the terminal via an RRC message; configuration parameters of the first message include a height offset granularity, first distance thresholds corresponding to different height ranges, and second reference point information.

[0250] The first distance threshold includes a first distance threshold between the terminal and a serving cell; and a first distance threshold between the terminal and a neighboring cell.

[0251] Optionally, the second reference point information corresponds to the second reference point information of the serving cell, such as expressed as (X_1, Y_1); and / or corresponds to the second reference point information of the neighboring cell, such as expressed as (X_2, Y_2).

[0252] For example, the height offset granularity indicated by the configuration parameters is: 1km.

[0253] In different height ranges, the first distance threshold between the corresponding terminal and the serving cell, and the first distance threshold between the corresponding terminal and the neighboring cell are expressed as:

[0254] Height range indication: 3 (representing the height range at this time is [3, 4]), DistanceThresh1_3 (representing the distance threshold between the UE and the serving cell), DistanceThresh2_3 (representing the distance threshold between the UE and the neighboring cell), the distance threshold represents the 3D distance from the terminal to the reference point;

[0255] Altitude range indication: 4, DistanceThresh1_4, DistanceThresh2_4;

[0256] Altitude range indication: 5, DistanceThresh1_5, DistanceThresh2_5;

[0257] Altitude range indication: 6, DistanceThresh1_6, DistanceThresh2_6;

[0258] Altitude range indication: 7, DistanceThresh1_7, DistanceThresh2_7;

[0259] Altitude range indication: 8, DistanceThresh1_8, DistanceThresh2_8;

[0260] Altitude range indication: 9, DistanceThresh1_9, DistanceThresh2_9;

[0261] Altitude range indication: 10, DistanceThresh1_10, DistanceThresh2_10.

[0262] DistanceThresh1 represents a first distance threshold between the terminal and the serving cell, and DistanceThresh2 represents a first distance threshold between the terminal and the neighboring cell.

[0263] Using this implementation, combined with Figure 8As shown, the terminal can determine the first distance threshold between the terminal and the service cell and the first distance threshold between the terminal and the adjacent phase area according to the current altitude and altitude range configuration information, and use the determined first distance threshold between the terminal and the service cell as the target distance threshold, and use the second reference point information of the service cell, such as (X_1, Y_1) as the target reference point information to determine the distance judgment result of the terminal relative to the service cell; in addition, use the determined first distance threshold between the terminal and the adjacent cell as the target distance threshold, and use the second reference point information of the adjacent cell as the target reference point information to determine the distance judgment result of the terminal relative to the adjacent cell; according to the distance judgment result of the terminal relative to the service cell and the distance judgment result of the terminal relative to the adjacent cell, and based on the conditional switching criterion of the distance, perform a conditional switching operation.

[0264] Combination Figure 8 As shown, for example, when the current height of the terminal is 5.3 km, the corresponding first distance threshold DistanceThresh1_5 (corresponding to the first distance threshold of the serving cell) and DistanceThresh2_5 (corresponding to the first distance threshold of the adjacent cell) are selected according to the current height.

[0265] In this way, the terminal can calculate the distance of the terminal relative to the reference point of the service cell based on the current position coordinates and the second reference point information of the service cell (used to indicate the coordinates corresponding to the center point position of the service cell), and compare the calculated distance with the first distance threshold of the corresponding service cell to obtain a first distance comparison result; and can calculate the distance of the terminal relative to the reference point of the adjacent cell based on the current position coordinates and the second reference point information of the adjacent cell (used to indicate the coordinates corresponding to the center point position of the adjacent cell), and compare the calculated distance with the first distance threshold of the corresponding adjacent cell to obtain a second distance comparison result; according to the first comparison result and the second comparison result, a conditional switching operation is performed based on the conditional switching criterion of the distance.

[0266] Implementation Method 4

[0267] In this implementation manner, the network device sends a first message to the terminal through an RRC message; the configuration parameters of the first message include:

[0268] A first distance for calculating a second distance threshold, the first distance being used to indicate a distance between the terminal and a target reference point in a horizontal direction; the first distance includes a first distance corresponding to a serving cell, such as expressed as DistanceThresh1, and includes a first distance corresponding to a neighboring cell, such as expressed as DistanceThresh2;

[0269] The second reference point information includes the second reference point information corresponding to the serving cell, such as represented by (X_1, Y_1, Z_1) and the second reference point information corresponding to the adjacent cell, such as represented by (X_2, Y_2, Z_2).

[0270] By adopting this implementation mode, the terminal can calculate the second distance threshold of the terminal corresponding to the service cell according to the first distance corresponding to the service cell and the second reference point information of the corresponding service cell, and calculate the distance of the terminal relative to the position point corresponding to the second reference point information according to the current position coordinates of the terminal and the second reference point information of the corresponding service cell, compare the calculated distance with the second distance threshold of the corresponding service cell, and obtain the first distance comparison result of the terminal relative to the service cell; and the terminal can calculate the second distance threshold of the terminal corresponding to the adjacent cell according to the first distance of the adjacent cell and the second reference point information of the corresponding adjacent cell, and calculate the distance of the terminal relative to the position point corresponding to the second reference point information according to the current position coordinates of the terminal and the second reference point information of the corresponding adjacent cell, compare the calculated distance with the second distance threshold of the corresponding adjacent cell, and obtain the second distance comparison result of the terminal relative to the adjacent cell; according to the first comparison result and the second comparison result, a conditional switching operation is performed based on the conditional switching criterion of the distance.

[0271] Combination Fig. 9 As shown, for example, the terminal uses the first distance DistanceThresh1 ( Fig. 9 denoted as D1) and the second reference point information (X_1, Y_1, Z_1) of the corresponding serving cell, calculate the second distance threshold distanceThresh1_UE ( Fig. 9 denoted as D1_UE in the figure:

[0272]

[0273] Wherein, H is the current height of the terminal, Href_1 is the reference point height of the serving cell; distanceThresh1_UE is the second distance threshold of the terminal corresponding to the serving cell;

[0274] The terminal calculates the first distance DistanceThresh2 ( Fig. 9 denoted as D2) and the second reference point information (X_2, Y_2, Z_2) corresponding to the adjacent cell, calculate the second distance threshold distanceThresh2_UE ( Fig. 9 denoted as D2_UE in the figure:

[0275]

[0276] Among them, H is the current height of the terminal, and Href_2 is the reference point height of the adjacent cell.

[0277] With this implementation, a conditional switching operation can be performed based on a conditional switching criterion of distance according to the calculated second distance threshold corresponding to the serving cell and the second distance threshold corresponding to the neighboring cell.
