It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0069] To facilitate understanding of the cell handover method in this application embodiment, the following related content will be introduced first:

[0070] I. Non-terrestrial networks (NTN)

[0071] Typical NTN deployment scenarios include Figure 2 As shown, the link between the UE and the satellite is called the service link, and the link between the satellite and the ground gateway is called the feeder link.

[0072] NTN communication systems include two types: transparent payload-based NTN communication systems and regenerative payload-based NTN communication systems. In Releases 17 and 18 of the Third Generation Partnership Project (3GPP), only transparent payload-based NTN communication systems were considered. In this deployment environment, terminals, base stations, and core network equipment are all deployed on the ground, and communication data between terminals and network equipment is relayed via satellite. In this system, the satellite is only used to relay data between the base station and the terminal; it does not decode or process this data. Release 19 of 3GPP extended this to regenerative payload-based NTN systems. In this deployment environment, the satellite has all the functions of a base station and can decode and process uplink or downlink data.

[0073] Based on satellite orbital altitude, NTN communication systems are divided into high-Earth orbit (GEO), low-Earth orbit (LEO), and medium-Earth orbit (MEO) satellite communication systems. GEO satellites are commonly found in high-Earth orbits, with an altitude of 35,786 km, and are stationary relative to the Earth's surface. Low-Earth orbit (LEO) satellites typically have an altitude range of 600 km to 1200 km. Medium-Earth orbit (MEO) satellites typically have an altitude range of 2000 km to 10000 km.

[0074] II. NTN Beam Hopping (BH)

[0075] In NTN communication systems, due to limited downlink transmission power, satellites need to use time-division dynamic satellite beamhopping to transmit and receive data across one or more satellite beam coverage areas. This means the satellite transmits and receives data across one or more satellite beam coverage areas during a certain time period, and then transmits and receives data across another one or more satellite beam coverage areas during a different time period. For example, a satellite may have 20 satellite beam coverage areas, but it cannot illuminate all 20 simultaneously. In practice, the satellite can illuminate satellite beam coverage areas #1 / 4 / 7 / 10 / 15 / 17 / 19 during the T1-T2 time interval (other coverage areas have no signal), allowing UEs within these coverage areas to transmit and receive data normally. Then, it can illuminate satellite beam coverage areas #2 / 5 / 8 / 12 / 15 / 16 / 19 during the T2-T3 time interval, as shown below. Figure 3 As shown, and so on.

[0076] III. NTN Condition Switching

[0077] Traditional conditional handover refers to the network pre-configuring the configuration information of candidate cells and associating corresponding execution conditions with each candidate cell. The UE evaluates each candidate cell based on the execution conditions. When the evaluation finds that all execution conditions of a candidate cell are met, the UE considers that cell to be triggered. If multiple triggered cells exist, the UE selects one of the triggered cells as the target cell based on its implementation; otherwise, the triggered cell is directly determined as the target cell, and the configuration information of the target cell is executed to complete the handover process by accessing the target cell.

[0078] Among them, NTN conditional handover utilizes the traditional conditional handover concept, but the difference lies in the fact that in the NTN scenario, based on the characteristics of the NTN network, such as cell mobility, large coverage, and predictable cell conditions using ephemeris information, in addition to the traditional execution conditions based on Radio Resource Management (RRM) measurements, time-based and location-distance-based execution conditions are also introduced.

[0079] The cell handover method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0080] See Figure 4 The embodiments of this application provide a cell handover method, which may include the following steps 401 to 403:

[0081] Step 401: The terminal determines the cell that was triggered;

[0082] It is understood that the triggered cell may include one or more cells;

[0083] Wherein, the terminal determines that the triggered cell includes at least one of the following A-1 to A-4:

[0084] Item A-1: ​​The terminal uses relaxed execution conditions to perform condition evaluation on the first candidate cell and determines the cell that meets the execution conditions as the triggered cell;

[0085] In item A-1, a cell that meets the implementation conditions can refer to a cell that meets one or more relaxed implementation conditions.

[0086] In addition, the relaxed execution conditions can be understood as: adjustments based on existing execution conditions. For example, if the Time to Trigger (TTT) in the existing execution conditions is set to 2ms, the TTT in the relaxed execution conditions can be set to 0; or, if the execution condition 1 configured by the network-side device for candidate cell 1 is an A4 event with an RSRP threshold of 2dB, then the RSRP threshold in the relaxed execution conditions is 1dB.

[0087] In this context, when the network-side device switches the configuration conditions to the terminal, in addition to configuring the execution conditions used in the existing technology (i.e., the execution conditions used in the existing protocol version), it can also configure relaxed execution conditions; or, the terminal can relax the execution conditions used in the existing technology according to the first rule to obtain relaxed execution conditions. The first rule can be a rule agreed upon by the protocol, such as setting TTT to 0.

[0088] In addition, the network-side equipment can configure corresponding execution conditions for each candidate cell. Therefore, the relaxed execution conditions in A-1 can be the relaxed execution conditions for the first candidate cell, such as the execution conditions after relaxing the execution conditions corresponding to the first candidate cell.

[0089] That is, in A-1, the terminal can use the relaxed execution conditions of the first candidate cell to evaluate the first candidate cell and determine the first candidate cell that meets the execution conditions as the cell to be triggered.

[0090] Item A-2: The terminal will determine the cell that meets one execution condition as the triggered cell; that is, when a candidate cell is configured with multiple execution conditions, if the candidate cell meets any one of the execution conditions, the candidate cell can be determined as the triggered cell, and it is not necessary for all of the multiple execution conditions to be met before it is determined as the triggered cell.

[0091] Among them, the execution conditions in item A-2 can include relaxed execution conditions or non-relaxed execution conditions (i.e., the execution conditions currently configured on the network side). That is, in item A-2, the terminal can determine a cell that meets a relaxed execution condition as the triggered cell, or determine a cell that meets a non-relaxed execution condition as the triggered cell.

[0092] In other words, it can be understood that since there is no "relaxed" limitation before "execution condition" in this article, "execution condition" can refer to a relaxed execution condition or a non-relaxed execution condition.

[0093] In addition, when the triggered cell is determined by items A-1 and A-2, it can be specifically: the terminal uses relaxed execution conditions to perform condition evaluation on the first candidate cell, and determines the cell that meets a relaxed execution condition as the triggered cell.

[0094] Item A-3: The terminal selects the second candidate cell as the triggered cell;

[0095] As indicated in item A-3, in this embodiment of the application, the terminal can select a specific second candidate cell as the triggered cell. For example, the second candidate cell can be a cell that meets specific conditions, which will be described later (refer to the relevant content in G-1 to G-20 below).

[0096] Item A-4: The terminal performs condition evaluation on the third candidate cell and determines the cell that meets the execution conditions as the triggered cell. The third candidate cell includes a portion of the candidate cells configured by the network-side equipment for the terminal.

[0097] As can be seen from item A-4, in the embodiments of this application, when performing condition evaluation, the terminal may only perform condition evaluation on a portion of the candidate cells configured for the terminal by the network-side device, rather than performing condition evaluation on all candidate cells.

[0098] It should be noted that the aforementioned first candidate cell may include one or more cells; the aforementioned second candidate cell may include one or more cells; the aforementioned third candidate cell may include one or more cells.

[0099] Optionally, at least one of the first candidate cell, the second candidate cell, and the third candidate cell satisfies at least one of the following G-1 to G-20:

[0100] Item G-1: The execution condition is met; the execution condition can be a relaxed execution condition or a non-relaxed execution condition.

[0101] Item G-2: The signal quality is the best among the candidate cells configured for the terminal by the network-side equipment;

[0102] Item G-3: The candidate cell configured by the network-side device for the terminal is closest to the terminal;

[0103] G-4: The cell is not configured with at least one of beam DTX or beam DRX;

[0104] G-5: At least one of beam DTX and beam DRX is not activated in the cell;

[0105] G-6: The beam covering the terminal in the cell is not configured with at least one of beam DTX and beam DRX;

[0106] G-7: At least one of beam DTX and beam DRX is not activated in the beam covering the terminal in the cell;

[0107] G-8: The beam covering the terminal in the cell is configured with at least one of beam DTX and beam DRX, but it is in an active state;

[0108] G-9: The time for the beam covering the terminal in the cell to transition to the deactivated state is greater than the fifteenth time.

[0109] Item G-10: The remaining service time of the beam covering the terminal in the cell is greater than the sixteenth time.

[0110] G-11: The beam covering the terminal in the cell is deactivated after the seventeenth time.

[0111] Item G-12: The beam covering the terminal in the cell expires after the eighteenth time.

[0112] G-13: The area in the cell covering the terminal is not configured with at least one of beam DTX and beam DRX;

[0113] G-14: At least one of beam DTX and beam DRX is not activated in the area of ​​the cell covering the terminal;

[0114] G-15: The area in the cell covering the terminal is configured with at least one of beam DTX and beam DRX, but its beam is active;

[0115] G-16: The time for the beam state of the area covering the terminal in the cell to change to the deactivated state is greater than the nineteenth time.

[0116] Item G-17: The remaining service time of the beam in the area covering the terminal in the cell is greater than the twentieth time.

[0117] G-18: The beam in the area covering the terminal in the cell is deactivated after the 21st time.

[0118] Item G-19: The beam covering the area of ​​the terminal in the cell expires after the twenty-second time.

[0119] Item G-20: The cell belongs to the candidate cells configured by the network-side equipment for the terminal.

[0120] Therefore, the first candidate cell can satisfy at least one of G-1 to G-20, the second candidate cell can also satisfy at least one of G-1 to G-20, and the third candidate cell can also satisfy at least one of G-1 to G-20. That is, the first candidate cell, the second candidate cell, and the third candidate cell can satisfy one or more of the contents of G-1 to G-20, which can be the same or different.

[0121] For example, when the first candidate cell satisfies at least one of G-2 to G-20, in item A-1 above, the terminal uses relaxed execution conditions to evaluate the first candidate cell that satisfies at least one of G-2 to G-20;

[0122] Alternatively, for example, when the second candidate cell satisfies at least one of G-1 to G-20 above, in item A-3 above, the terminal determines the second candidate cell that satisfies at least one of G-1 to G-20 as the triggered cell;

[0123] Alternatively, for example, when the third candidate cell satisfies at least one of G-2 to G-20 above, in item A-4 above, the terminal evaluates the third candidate cell among the candidate cells configured for the terminal by the network-side device that satisfies at least one of G-1 to G-20.

[0124] Step 402: The terminal determines the target cell among the triggered cells.

[0125] Step 403: The terminal switches to the target cell.

[0126] As can be seen from steps 402 to 403, after the terminal determines the triggered cell, it can select the target cell from the triggered cells and switch to the target cell.

[0127] As can be seen from steps 401 to 403 above, in this embodiment of the application, the terminal can determine the triggered cell and the target cell among the triggered cells, and then switch to the target cell. When determining the triggered cell, the terminal can use relaxed execution conditions to evaluate the conditions of the first candidate cell and determine the cell that meets the execution conditions as the triggered cell, or determine the cell that meets one execution condition as the triggered cell, or select the second candidate cell as the triggered cell, or evaluate some candidate cells (i.e., the third candidate cell) configured by the network side equipment to the terminal, thereby determining the cell that meets the execution conditions as the triggered cell.

[0128] As can be seen, in the embodiments of this application, the terminal can use relaxed execution conditions to obtain the triggered cell. In this way, by relaxing the execution conditions, it is easier to evaluate and determine the cell that meets the requirements (i.e., the triggered cell); or, a cell that meets an execution condition can be determined as the triggered cell, which is also easier to evaluate and determine the cell that meets the requirements (i.e., the triggered cell); or, a specific second candidate cell can be directly selected as the triggered cell, which makes up for the inability of the terminal to evaluate and find a cell that meets the requirements when performing condition evaluation according to the existing mechanism; or, the terminal can perform condition evaluation only on a specific part of the candidate cells configured for the terminal by the network side device to obtain the triggered cell, which can also make up for the inability of the terminal to evaluate and find a cell that meets the requirements when performing condition evaluation according to the existing mechanism.

[0129] Therefore, the embodiments of this application can solve the problem in the prior art that in certain scenarios, if the terminal performs condition evaluation according to the existing mechanism, it may be unable to evaluate and find a cell that meets the requirements, thus failing to perform cell handover in a timely manner and affecting the terminal's service transmission.

[0130] Optionally, in step 403 above, the terminal determines the target cell among the triggered cells, including one of the following:

[0131] The terminal selects any one of the triggered cells as the target cell;

[0132] The terminal determines any cell among the triggered cells that meets the first condition as the target cell.

[0133] Therefore, in this embodiment of the application, the terminal can select any cell as the target cell from the triggered cells, or it can select the triggered cell that meets the first condition from the triggered cells, and then select any cell as the target cell from the triggered cells that meet the first condition.

[0134] Optionally, the first condition includes at least one of the following B-1 to B-15:

[0135] Item B-1: The cell is not configured with at least one of beam discontinuous transmission (beam DTX) or beam discontinuous reception (beam DRX);

[0136] Item B-2: At least one of the beam DTX and beam DRX beams is not activated in the cell;

[0137] For items B-1 and B-2, if a cell is not configured or activated with at least one of beam DTX or beam DRX, it means that if the terminal accesses the cell, it can normally send and receive data. Therefore, a triggered cell that is not configured or activated with at least one of beam DTX or beam DRX can be used as a target cell. In this way, after the terminal switches to the target cell, it can normally send and receive data, thereby avoiding the interruption of the current service.

[0138] Item B-3: The beam covering the terminal in the cell is not configured with at least one of beam DTX and beam DRX;

[0139] Item B-4: At least one of beam DTX and beam DRX is not activated in the beam covering the terminal in the cell;

[0140] For items B-3 and B-4, if the beam covering the terminal in a cell is not configured or at least one of beam DTX and beam DRX is not activated, it means that if the terminal accesses the cell, it can normally receive and send data through the beam covering the terminal. Therefore, the triggered cell where the beam covering the terminal is not configured or at least one of beam DTX and beam DRX is not activated can be used as the target cell. In this way, after the terminal switches to the target cell, it can normally receive and send data through the beam covering the terminal, thereby avoiding the interruption of the current service.

[0141] It should be noted that "coverage terminal" in this article refers to "the location of the coverage terminal".

[0142] Item B-5: The beam covering the terminal in the cell is configured with at least one of beam DTX and beam DRX, but it is in an active state;

[0143] If the beam covering a terminal in a cell is configured or activated with at least one of beam DTX and beam DRX, and is in an active state, it means that if the terminal accesses the cell, it can normally send and receive data through the beam covering the terminal. Therefore, if the beam covering a terminal in a triggered cell is configured or activated with at least one of beam DTX and beam DRX, and is in an active state, the triggered cell can be used as a target cell. In this way, after the terminal switches to the target cell, it can normally send and receive data through the beam covering the terminal, thereby avoiding the interruption of the current service.

[0144] In addition, the beam being in an active state as described in this article can also be understood as at least one of the following: the beam being lit up or the beam being turned on; the beam being in an inactive state as described in this article can also be understood as at least one of the following: the beam being unlit or the beam being turned off.

[0145] Item B-6: The time for the beam covering the terminal in the cell to transition to the deactivated state is greater than the first time; where the first time represents a duration; that is, Item B-6 means that the duration for which the beam covering the terminal in the cell is in the deactivated state is greater than the first time.

[0146] If the time it takes for a terminal's beam to transition to an inactive state in a cell to exceed a certain threshold, it means that the beam of the terminal in that cell will soon become active. Therefore, if a terminal switches to that cell, it can resume normal data transmission and reception shortly afterward, reducing the probability of service interruption. Thus, if the time it takes for a terminal's beam to transition to an inactive state in a triggered cell to exceed a certain threshold, that triggered cell can be designated as the target cell.

[0147] Item B-7: The remaining service time of the beam covering the terminal in the cell is greater than the second time; where the second time represents a duration; that is, Item B-7 means that the remaining service time of the beam covering the terminal in the cell is greater than the second time.

[0148] It is understood that the remaining service time of a beam in this article refers to the time elapsed from the current time to the expiration time of the beam's service.

[0149] If the remaining service time of the beam covering the terminal in a cell is greater than the second time, it means that the remaining time of the beam covering the terminal in that cell is active is long enough to support the data transmission of the terminal's current service. Therefore, if the remaining service time of the beam covering the terminal in a triggered cell is greater than the second time, the triggered cell can be used as the target cell.

[0150] Item B-8: The beam covering the terminal in the cell is deactivated after the third time; where the third time refers to a moment or point in time;

[0151] If the beam of a terminal in a cell only becomes deactivated after the third time interval, it means that the remaining active time of the beam of the terminal in that cell is long enough to support the data transmission of the terminal's current service. Therefore, if the beam of a terminal in a triggered cell becomes deactivated after the third time interval, the triggered cell can be used as the target cell.

[0152] Item B-9: The beam covering the terminal in the cell expires after the fourth time; where the fourth time represents a moment or point in time;

[0153] If the service time of the beam covering the terminal in a cell expires after the fourth time, it means that the remaining service time of the beam covering the terminal in that cell is long enough to support the data transmission of the terminal's current service. Therefore, if the beam covering the terminal in a triggered cell expires after the fourth time, the triggered cell can be used as the target cell.

[0154] Item B-10: The area in the cell covering the terminal is configured with at least one of beam DTX and beam DRX, and its beam is in an active state;

[0155] If the area covering a terminal in a cell is configured or activated with at least one of beam DTX and beam DRX, and is in an active state, it means that if the terminal accesses the cell, it can normally send and receive data through the beam of the area covering the terminal. Therefore, if the area covering a terminal in a triggered cell is configured or activated with at least one of beam DTX and beam DRX, and is in an active state, the triggered cell can be used as a target cell. In this way, after the terminal switches to the target cell, it can normally send and receive data through the beam of the area covering the terminal, thereby avoiding the interruption of the current service.

[0156] Item B-11: The time for the beam state of the area covering the terminal in the cell to change to the deactivated state is greater than the fifth time; where the fifth time represents a duration; that is, Item B-11 means that the duration for which the beam of the area covering the terminal in the cell is in the deactivated state is greater than the fifth time.

[0157] In this context, if the time it takes for the beam state of the area covering a terminal in a cell to transition to an inactive state is greater than the fifth time interval, it indicates that the beam state of the area covered by that cell will soon become active. Therefore, if a terminal switches to that cell, it can resume normal data transmission and reception shortly afterward, reducing the probability of service interruption. Thus, if the time it takes for the beam state of the area covering a terminal in a triggered cell to transition to an inactive state is greater than the fifth time interval, that triggered cell can be designated as the target cell.

[0158] Item B-12: The remaining service time of the beam in the area covering the terminal in the cell is greater than the sixth time; where the sixth time represents a duration; that is, Item B-12 means that the remaining service time of the beam in the area covering the terminal in the cell is greater than the sixth time.

[0159] If the remaining service time of the beam covering the terminal area in a cell is greater than the sixth time, it means that the remaining time of the beam in the area covered by the cell is active long enough to support the data transmission of the terminal's current service. Therefore, if the remaining service time of the beam covering the terminal area of ​​a triggered cell is greater than the sixth time, the triggered cell can be used as the target cell.

[0160] Item B-13: The beam covering the area of ​​the terminal in the cell is deactivated after the seventh time; where the seventh time represents a moment or point in time;

[0161] If the beam of the area covering the terminal in a cell only becomes deactivated after the seventh time, it means that the remaining time of the beam in the area covering the terminal in that cell is active is long enough to support the data transmission of the terminal's current service. Therefore, if the beam of the area covering the terminal in a triggered cell becomes deactivated after the seventh time, the triggered cell can be used as the target cell.

[0162] Item B-14: The service time of the beam covering the area of ​​the terminal in the cell expires after the eighth time; where the eighth time represents a moment or point in time;

[0163] If the service time of the beam covering the terminal area in a cell expires after the eighth time, it means that the remaining service time of the beam covering the terminal area in that cell is long enough to support the data transmission of the terminal's current service. Therefore, if the beam covering the terminal area of ​​a triggered cell expires after the eighth time, the triggered cell can be used as the target cell.

[0164] Item B-15: The cell has the strongest signal quality.

[0165] In the case of multiple triggered cells, selecting the cell with the strongest signal quality from among the multiple triggered cells as the target cell can improve the data transmission quality after the terminal switches to the target cell.

[0166] Additionally, it should be noted that the coverage area of ​​a community can be divided into multiple areas, and each area can correspond to one or more beams. Therefore, the beams of the aforementioned areas can be understood as the beams corresponding to those areas.

[0167] Furthermore, it is understood that the first condition may also include at least one of the following:

[0168] The remaining active time (i.e., the time from the current time until the beam covering the terminal in the cell becomes inactive) is greater than the twenty-third time; (meaning that the beam will not become inactive for a long time).

[0169] The remaining active time of the beam in the area covering the terminal in the cell (i.e., the time from the current time to the time when the beam becomes deactivated) is greater than the twenty-fourth time (meaning that the beam will not become deactivated for a long time).

[0170] If the beam or area of ​​a triggered cell that covers a terminal does not become deactivated for a long time, the remaining time can support the data transmission of the terminal's services. Therefore, in this case, the triggered cell can be used as the target cell.

[0171] Optionally, in step 401 above, the terminal determines the triggered cell, including:

[0172] If the terminal meets the second condition, the terminal determines the triggered cell;

[0173] The second condition includes at least one of the following C-1 to C-12:

[0174] C-1: The beam used by the terminal is configured to transmit at least one of beam DTX and beam DRX;

[0175] C-2: The beam used by the terminal is activated with at least one of beam DTX and beam DRX;

[0176] C-3: The area where the terminal is located is configured with at least one of beam DTX and beam DRX;

[0177] C-4: At least one of beam DTX and beam DRX is activated in the area where the terminal is located;

[0178] It should be noted that the beam used by the terminal can be understood as the beam currently used by the terminal; the area where the terminal is located can be understood as the area where the terminal is currently located. Here, "currently" in "the area where the terminal is currently located" refers to the moment when determining whether the terminal meets the second condition; that is, the beam currently used by the terminal refers to the beam used by the terminal at the moment it determines whether it meets the second condition; and the area where the terminal is currently located refers to the area where the terminal is located at the moment it determines whether it meets the second condition.

[0179] For items C-1 to C-4, if the beam used by the terminal or the area it is located in is configured or activated with at least one of beam DTX and beam DRX, then the beam used by the terminal or the beam in the area it is located in will be in an inactive state for a period of time. During this time, the beam used by the terminal or the beam in the area it is located in cannot provide service because it is turned off, which will cause the terminal to trigger reconstruction or even enter an idle state, thereby affecting the terminal's service transmission. Therefore, if the beam used by the terminal or the area it is located in is configured or activated with at least one of beam DTX and beam DRX, the terminal can determine the triggered cell, then determine the target cell among the triggered cells, and then hand over to the target cell. This allows the terminal to perform cell handover in a timely manner to avoid service interruption.

[0180] C-5: The beam used by the terminal is in a deactivated state;

[0181] C-6: The beam state of the area where the terminal is located is in a deactivated state;

[0182] For items C-5 to C-6, when the beam used by the terminal or the beam in its area is inactive, the beam used by the terminal or the beam in its area cannot provide service due to being shut down. This will cause the terminal to trigger a rebuild or even enter an idle state, thus affecting the terminal's service transmission. Therefore, if the beam used by the terminal or the beam in its area is inactive, the terminal can determine the triggered cell, identify the target cell among the triggered cells, and then hand over to the target cell. This allows the terminal to perform a timely cell handover to avoid service interruption.

[0183] Item C-7: The beam used by the terminal is deactivated before the ninth time, where the ninth time represents a moment or point in time;

[0184] If the beam used by the terminal becomes deactivated before the ninth time interval, the beam will be unable to provide service after a certain period, triggering a reconstruction or even causing the terminal to enter an idle state, thus affecting service transmission. Therefore, if the beam used by the terminal becomes deactivated before the ninth time interval, the terminal can identify the triggered cell, determine the target cell among the triggered cells, and then handover to the target cell. This allows the terminal to perform a timely cell handover to avoid service interruption.

[0185] Item C-8: The beam state of the area where the terminal is located changes to a deactivated state before the tenth time, where the tenth time represents a moment or point in time;

[0186] If the beam in the terminal's area becomes deactivated before the tenth time interval, the beam will be unable to provide service after a certain period, triggering a rebuild or even causing the terminal to enter an idle state, thus affecting service transmission. Therefore, if the beam in the terminal's area becomes deactivated before the tenth time interval, the terminal can identify the triggered cell, determine the target cell among the triggered cells, and then handover to the target cell. This allows the terminal to perform a timely cell handover to avoid service interruption.

[0187] Item C-9: The service time of the beam used by the terminal expires before the eleventh time, where the eleventh time represents a moment or point in time;

[0188] If the beam used by the terminal expires before the eleventh time, the remaining service time of the beam may be insufficient to support the data transmission of the terminal's services. Therefore, if the beam used by the terminal expires before the eleventh time, the terminal can identify the triggered cell, determine the target cell among the triggered cells, and then hand over to the target cell. This allows the terminal to perform a timely cell handover to avoid service interruption.

[0189] Item C-10: The service time of the beam in the area where the terminal is located expires before the twelfth time, where the twelfth time represents a moment or point in time.

[0190] If the beam in the terminal's area expires before the twelfth time, the remaining service time of the beam in that area may be insufficient to support the data transmission of the terminal's services. Therefore, if the beam in the terminal's area expires after the eighth time, the terminal can identify the triggered cell, determine the target cell among the triggered cells, and then hand over to the target cell. This allows the terminal to perform a timely cell handover to avoid service interruption.

[0191] Item C-11: The remaining service time of the beam used by the terminal is greater than or less than the thirteenth time; where the thirteenth time represents a duration.

[0192] If the remaining service time of the beam used by the terminal is less than the thirteenth time, it means that the remaining service time of the beam is insufficient to support the data transmission of the terminal's services. Therefore, in this case, the terminal can determine the triggered cell, then determine the target cell among the triggered cells, and then switch to the target cell. This allows the terminal to perform cell handover in a timely manner to avoid service interruption.

[0193] Item C-12: The remaining service time of the beam in the area where the terminal is located is greater than the fourteenth time, where the fourteenth time represents a duration.

[0194] If the remaining service time of the beam in the area where the terminal is located is less than the fourteenth time, it means that the remaining service time of the beam is insufficient to support the data transmission of the terminal's services. Therefore, in this case, the terminal can determine the triggered cell, then determine the target cell among the triggered cells, and then switch to the target cell. This allows the terminal to perform cell handover in a timely manner to avoid service interruption.

[0195] Furthermore, it is understood that the second condition may also include at least one of the following:

[0196] The remaining active time for the beam used by the terminal (i.e., the time from the current time until the beam used by the terminal becomes inactive) is less than the twenty-fifth time; (indicating that the beam used by the terminal will soon become inactive).

[0197] The remaining active time of the beam in the area where the terminal is located (i.e., the time from the current time to the time when the beam used by the terminal becomes deactivated) is less than the twenty-sixth time (meaning that the beam in the area where the terminal is located will soon become deactivated).

[0198] If the beam used by the terminal or the beam in the area where it is located will soon be deactivated, the remaining time will not be sufficient to support the data transmission of the terminal's services. Therefore, in this case, the terminal can identify the triggered cell, then identify the target cell among the triggered cells, and then switch to the target cell. This allows the terminal to perform cell handover in a timely manner to avoid service interruption.

[0199] Additionally, it should be noted that the service time of a beam can also be understood as the activation time, which refers to the time after which the beam will be turned off or deactivated.

[0200] Alternatively, when the terminal meets the second condition described above, it can also perform a normal condition assessment according to existing mechanisms to determine the triggered cell. Optionally, the method further includes:

[0201] The terminal acquires at least one of first auxiliary information and second auxiliary information, wherein the first auxiliary information is used to indicate the beam pattern information of the serving cell of the terminal, and the second auxiliary information is used to indicate the service time information of the serving cell of the terminal.

[0202] The terminal can receive at least one of the first auxiliary information and the second auxiliary information sent by the network-side device.

[0203] Optionally, the method further includes:

[0204] The terminal performs at least one of the following V-1 to V-2:

[0205] V-1 item: Based on the first auxiliary information and the location information of the terminal, determine at least one of the beam pattern information of the beam used by the terminal and the beam pattern information of the area where it is located;

[0206] V-2: Based on the second auxiliary information and the location information of the terminal, determine at least one of the service time information of the beam used by the terminal and the service time information of the beam in the area where the terminal is located.

[0207] It is understandable that after the terminal executes at least one of V-1 to V-2 above, it can determine whether the terminal meets the second condition above based on the content determined by at least one of V-1 to V-2 (i.e., the beam pattern information of the beam used by the terminal, the beam pattern information of the area where the terminal is located, the service time information of the beam in the area where the terminal is located, and the service time information of the beam in the area where the terminal is located).

[0208] For example, in this embodiment of the application, the terminal can obtain first auxiliary information, thereby determining at least one of the beam pattern information of the beam used by the terminal and the beam pattern information of the area where the terminal is located, and determining whether the terminal meets the above-mentioned second condition based on at least one of the beam pattern information of the beam used by the terminal and the beam pattern information of the area where the terminal is located.

[0209] Alternatively, by way of example, in this embodiment of the application, the terminal may obtain second auxiliary information, thereby determining the service time information of the beam in the area where the terminal is located and the service time information of the beam in the area where the terminal is located based on the second auxiliary information, and determining whether the terminal meets the above-mentioned second condition based on the determined service time information of the beam in the area where the terminal is located and the service time information of the beam in the area where the terminal is located.

[0210] Optionally, the first auxiliary information includes at least one of the following D-1 to D-10:

[0211] D-1 item: First beam pattern information of at least one beam in the serving cell, such as beam pattern information of all beams in the serving cell that are configured with at least one of beam DTX and beam DRX.

[0212] Item D-2: Coverage information associated with the first beam pattern information;

[0213] Item D-3: Beam identification information associated with the first beam pattern information;

[0214] Item D-4: Second beam pattern information for at least one area within the serving cell;

[0215] Item D-5: Coverage information associated with the second beam pattern information;

[0216] Item D-6: Beam pattern information of the beam used by the terminal;

[0217] Item D-7: Beam pattern information for the area where the terminal is located;

[0218] D-8: First indication information, used to indicate whether the beam used by the terminal is configured with at least one of beam DTX and beam DRX, or whether the beam used by the terminal is activated with at least one of beam DTX and beam DRX;

[0219] D-9: Second indication information, used to indicate whether the area where the terminal is located is configured with at least one of beam DTX and beam DRX, or whether the area where the terminal is located is activated with at least one of beam DTX and beam DRX;

[0220] Item D-10: Third indication information, used to indicate at least one of the ninth time, the tenth time, the eleventh time, the twelfth time, the thirteenth time, and the fourteenth time.

[0221] Wherein, based on the above-mentioned contents included in the first auxiliary information, the terminal determines at least one of the beam pattern information of the beam used by the terminal and the beam pattern information of the area where the terminal is located, and determines whether the terminal meets the above-mentioned second condition based on at least one of the beam pattern information of the beam used by the terminal and the beam pattern information of the area where the terminal is located. The specific process can be described in the first to third aspects as follows:

[0222] In the first aspect, where the first auxiliary information includes beam pattern information of at least one beam of the serving cell and coverage information associated with the beam pattern information:

[0223] If the first coverage information is not present in the first auxiliary information, the terminal determines that the beam used by the terminal is not configured or is not activated at least one of beam DTX and beam DRX, wherein the coverage of the beam indicated by the first coverage information covers the location of the terminal.

[0224] or,

[0225] If the first coverage information exists in the first auxiliary information, the terminal performs at least one of the following:

[0226] It is determined that the beam used by the terminal is configured or activated with beam DTX;

[0227] Based on the beam pattern information associated with the first coverage information in the first auxiliary information, determine whether the beam used by the terminal is in a deactivated state;

[0228] Based on the beam pattern information associated with the first coverage information in the first auxiliary information, it is determined whether the beam used by the terminal will be deactivated during the fifth time period.

[0229] Secondly, in the case where the first auxiliary information includes beam pattern information for at least one area of ​​the serving cell and coverage information associated with that beam pattern information:

[0230] If the second coverage information is not present in the first auxiliary information, the terminal determines that the area where the terminal is located has not been configured or activated with at least one of beam DTX and beam DRX, wherein the coverage area of ​​the area indicated by the second coverage information covers the location of the terminal.

[0231] or,

[0232] If the second coverage information exists in the first auxiliary information, the terminal performs at least one of the following:

[0233] It is determined that the region where the terminal is located has at least one of beam DTX and beam DRX configured or activated;

[0234] Based on the beam pattern information associated with the second coverage information in the first auxiliary information, determine whether the beam in the area where the terminal is located is in a deactivated state;

[0235] Based on the beam pattern information associated with the second coverage information in the first auxiliary information, it is determined whether the beam in the area where the terminal is located will be deactivated during the sixth time period.

[0236] Secondly: If the first auxiliary information does not contain beam pattern information covering the beam or area of ​​the terminal, then the terminal determines that the beam used by the terminal or the beam of the area where the terminal is located has not been configured or activated at least one of beam DTX and beam DRX.

[0237] If the first auxiliary information contains beam pattern information covering the beam or region of the terminal, the terminal performs at least one of the following:

[0238] It is determined that the beam used by the terminal or the area in which it is located is configured or activated with at least one of beam DTX and beam DRX.

[0239] Based on the beam pattern information covering the beam or area of ​​the terminal, it is determined whether the beam used by the terminal or the beam of the area where it is located is in a deactivated state.

[0240] Based on the beam pattern information of the beam covering the terminal, it is determined whether the beam used by the terminal will be deactivated during the fifth time period.

[0241] Based on the beam pattern information of the area covering the terminal, it is determined whether the beam in the area where the terminal is located will change to a deactivated state during the sixth time period.

[0242] To facilitate understanding of the content of the first to third aspects here, the following examples are provided:

[0243] Example 1: If the first auxiliary information includes the first beam pattern information of at least one beam within the serving cell, the coverage information associated with the first beam pattern information, and the beam identification information associated with the first beam pattern information, the terminal first determines that the beam it is using is beam 1 based on its location. Then, if the first auxiliary information does not provide the beam pattern information associated with beam 1, the terminal may assume that the beam it is using is not configured with at least one of beamDTX and beam DRX, or that the beam it is using is not activated with at least one of beamDTX and beam DRX.

[0244] If the first auxiliary information provides beam pattern information of the beam used by the terminal, the terminal can assume that the beam it uses is configured with at least one of beam DTX and beam DRX, or that the beam used by the terminal is activated with at least one of beam DTX and beam DRX. In this way, the terminal determines the beam state (on / off) of the beam used by the terminal based on the beam pattern information, and at least one of the remaining time of transitioning to off.

[0245] Alternatively, it can be understood as follows: if the first auxiliary information contains beam coverage range information for the location of the terminal, then the beam associated with the beam coverage range information is the beam used by the terminal. If the first auxiliary information provides beam pattern information of the beam used by the terminal, then the terminal can assume that the beam it uses is configured with at least one of beam DTX and beam DRX, or that the beam used by the terminal has activated at least one of beam DTX and beam DRX.

[0246] Example 2: If the first auxiliary information includes the second beam pattern information of at least one area within the serving cell and the coverage information associated with the second beam pattern information, the terminal first determines, based on its location, that the coverage area of ​​its location is coverage area 1 (i.e., the terminal is within coverage area 1); then, if the first auxiliary information does not provide the beam pattern information associated with coverage area 1, the terminal may assume that its location is not configured with at least one of beam DTX and beam DRX, or that the location of the terminal is not activated with at least one of beam DTX and beam DRX.

[0247] If the first auxiliary information provides beam pattern information associated with coverage area 1, the terminal can assume that its area is configured with at least one of beam DTX and beam DRX, or that the area where the terminal is located is activated with at least one of beam DTX and beam DRX. In this way, the terminal determines the beam state (on / off) of the beam in its area based on the beam pattern information, and at least one of the remaining time before it turns off.

[0248] Example 3: The network-side device will provide only the beam pattern information of the area where the terminal is located or the beam it is using, based on the terminal's location information. In this way, if the terminal receives the beam pattern information, the terminal will assume that the beam it is using or the area it is in is configured with at least one of beam DTX and beam DRX, or that the beam it is using or the area it is in is activated with at least one of beam DTX and beam DRX. The terminal can also determine the beam state (on / off) of the beam it is using based on the beam pattern information, including at least one of the remaining time before it turns off.

[0249] If the terminal does not receive beam pattern information, it implies that the beam or area it is using is not configured with at least one of beam DTX or beam DRX, or that the beam or area it is using is not activated with at least one of beam DTX or beam DRX.

[0250] Example 4: The network-side device can configure information based on the terminal's location information to indicate whether the beam used by the terminal or the area it is in has been configured / activated with at least one of beam DTX and beam DRX.

[0251] Optionally, the second auxiliary information includes at least one of the following E-1 to E-8:

[0252] E-1 item: First service time information of the beam in at least one area of ​​the serving cell;

[0253] Item E-2: Regional information associated with the first service time information;

[0254] E-3: Second service time information of at least one beam of the serving cell;

[0255] Item E-4: Beam identification information associated with the second service time information;

[0256] Item E-5: Coverage information associated with the second service time information;

[0257] E-6: Service time information of the beam used by the terminal;

[0258] E-7: Service time information of the beam in the area where the terminal is located;

[0259] E-8: Third indication information, used to indicate at least one of the ninth time, the tenth time, the eleventh time, the twelfth time, the thirteenth time, and the fourteenth time.

[0260] Specifically, based on the above-mentioned contents included in the second auxiliary information, the terminal determines the service time information of the beam in the area where the terminal is located and the service time information of the beam in the area where the terminal is located, and determines whether the terminal meets the above-mentioned second condition based on the determined service time information of the beam in the area where the terminal is located and the service time information of the beam in the area where the terminal is located. The specific process can be described in the following fourth to sixth aspects:

[0261] Fourthly, when the second auxiliary information includes service time information of at least one beam of the serving cell and coverage information associated with that service time information:

[0262] If the second auxiliary information does not contain the first coverage information, the terminal determines that the beam used by the terminal is not configured or not activated at least one of beam DTX and beam DRX, wherein the coverage of the beam indicated by the first coverage information covers the location of the terminal.

[0263] or,

[0264] If the second auxiliary information contains the first coverage information, the terminal performs at least one of the following:

[0265] It is determined that the beam used by the terminal is configured or activated with at least one of beam DTX and beam DRX;

[0266] Based on the service time information associated with the first coverage information in the second auxiliary information, it is determined whether the service time of the beam used by the terminal expires after the seventh time.

[0267] Fifthly, when the second auxiliary information includes service time information of the beam in at least one area of ​​the serving cell and coverage information associated with the service time information:

[0268] If the second coverage information is not present in the second auxiliary information, the terminal determines that the area where the terminal is located is not configured or activated with at least one of beam DTX and beam DRX, wherein the coverage area of ​​the area indicated by the second coverage information covers the location of the terminal.

[0269] or,

[0270] If the second coverage information is present in the second auxiliary information, the terminal performs at least one of the following:

[0271] It is determined that the region where the terminal is located has at least one of beam DTX and beam DRX configured or activated;

[0272] Based on the service time information associated with the second coverage information in the second auxiliary information, it is determined whether the service time of the beam in the area where the terminal is located expires after the eighth time.

[0273] Sixth aspect: If the second auxiliary information does not contain the service time information of the beam used by the terminal or the beam in the area where the terminal is located, then the terminal determines that the beam used by the terminal or the area where the terminal is located has not been configured or activated at least one of beam DTX and beam DRX.

[0274] or,

[0275] If the second auxiliary information contains service time information of the beam used by the terminal or the beam of the area where the terminal is located, then the terminal performs at least one of the following:

[0276] It is determined that the beam used by the terminal or the area in which it is located is configured or activated with at least one of beam DTX and beam DRX.

[0277] Based on the service time information of the beam used by the terminal, determine whether the service time of the beam used by the terminal expires after the seventh time.

[0278] Based on the service time information of the beam in the area where the terminal is located, determine whether the service time of the beam in the area where the terminal is located expires after the eighth time.

[0279] To facilitate understanding of aspects four through six here, the following examples are provided:

[0280] Example 1: The terminal first determines its location based on its geographical location. Then, based on the service time information of the beam of at least one area of ​​the serving cell provided in the second auxiliary information, and the associated area information, the terminal determines the service time information of the beam in its location. Optionally, if the terminal's location is not in an area associated with service time information in the second auxiliary information, it can be assumed that at least one of beam DTX and beam DRX is not configured or activated in the area where the terminal is located. For example, the second auxiliary information provides area 1 and its associated service time information 1, and area 2 and its associated service time information 2. The terminal determines that it is in area 1 based on its location, and the terminal can determine its service time based on service time information 1. For example, if service time information 1 is 10:00:00 on August 2, 2024, and the time is 8:00:00 on August 2, 2024, the terminal determines at least one of the following: the service end time is 10:00:00 on August 2, 2024, and the remaining service time is 2 hours and 00 minutes.

[0281] Example 2: The terminal first determines the beam it uses based on its geographical location; then, based on the service time information of at least one beam of the serving cell provided in the second auxiliary information, as well as the identification information and coverage information of the associated beam, it determines the service time information associated with the beam used by the terminal; optionally, if the terminal's location is not within the coverage area of ​​the beam associated with the service time information provided in the second auxiliary information, it can be considered that the beam used by the terminal has not been configured or activated (beam DTX, beam...). At least one of the following is provided in the DRX: For example, the second auxiliary information provides beam 1 and its associated service time information 1 and coverage area 1 of beam 1, beam 2 and its associated service time information 2 and coverage area 2 of beam 2. The terminal determines that it is within the coverage area of ​​beam 1 based on its location, that is, it determines that its service beam is beam 1. Furthermore, the terminal can determine that its beam service time information is service time information 1. For example, if service time information 1 is 10:00:00 on August 2, 2024, and the time is 8:00:00 on August 2, 2024, then the terminal determines at least one of the following: the service end time is 10:00:00 on August 2, 2024, and the remaining service time is 2 hours 00 minutes 00 seconds.

[0282] Example 3: The network-side device can provide only the service time information of the beam in the area where the terminal is located, or the service time information of the beam in which the terminal is located, based on the location information of the terminal. In this way, if the terminal receives the service time information, the terminal believes that the beam it is using or the area it is in is configured with at least one of beam DTX and beam DRX, or that the beam it is using or the area it is in is activated with at least one of beam DTX and beam DRX; and can determine the service time or remaining service time of the beam it is using or the area it is in based on the service time information.

[0283] If the terminal does not receive service time information, it implies that: the beam used or the area it is in is not configured with at least one of beam DTX or beam DRX, or the beam used or the area it is in is not activated with at least one of beam DTX or beam DRX.

[0284] Optionally, the method further includes:

[0285] Under at least one of the following L-1 to L-4 conditions, the terminal determines whether the terminal satisfies the second condition:

[0286] L-1: The time interval between the last determination of whether the terminal meets the second condition is the first time interval; that is, the terminal can be periodically determined to meet the second condition.

[0287] L-2: Receives a fourth indication message sent by the network-side device, wherein the fourth indication message is used to instruct the terminal to determine whether the terminal meets the second condition; that is, the terminal can determine whether it meets the second condition based on the indication from the network-side device.

[0288] L-3: The terminal moves and the range of movement exceeds the first threshold; that is, if the terminal moves and the range of movement exceeds the first threshold, the terminal can be triggered to determine whether it meets the second condition.

[0289] L-4: There is at least one triggered cell. That is, if there is at least one triggered cell, the terminal can be triggered to determine whether the second condition is met.

[0290] Therefore, in any of the cases described in L-1 to L-4, the terminal can be triggered to determine whether it meets the second condition. If the second condition is met, the triggered cell can be determined by the method described in at least one of A-1 to A-4 above. Then, the target cell can be determined in the triggered cell, and the terminal can be switched to the target cell.

[0291] Optionally, the relaxation execution conditions include at least one of the following F-1 to F-4:

[0292] F-1 item: Relaxed the measurement reporting event for continuous trigger time (TTT);

[0293] That is, when the terminal evaluates the execution conditions of the first candidate cell, it evaluates the execution conditions with a TTT of 0. For example, the network configures the execution condition 1 of candidate cell 1 with a TTT of 2ms, but in this case, the terminal evaluates the execution condition 1 of candidate cell 1 with a TTT of 0.

[0294] F-2: Measurement reporting events that relax signal quality thresholds;

[0295] That is, when the terminal evaluates the execution conditions of the first candidate cell, it relaxes its RSRP threshold. For example, the network-side device configures the execution condition 1 of candidate cell 1 as an A4 event, and its RSRP threshold is 2dB. However, when evaluating candidate cell 1, the terminal evaluates the execution conditions of candidate cell 1 according to the threshold of 1dB.

[0296] F-3: Measurement reporting event with relaxed location threshold; that is, when the terminal evaluates the execution conditions of the first candidate cell, it relaxes its location threshold;

[0297] Item F-4: Relaxed execution conditions for network-side device configuration.

[0298] When the terminal evaluates the first candidate cell, it uses the relaxed execution conditions configured by the network-side device for evaluation. Before this, the terminal can obtain the relaxed execution conditions configured by the network-side device. For example, the network-side device configures execution condition 1-1 and relaxed execution condition 1-2 for candidate cell 1, but when evaluating candidate cell 1, it uses execution condition 1-2 to evaluate candidate cell 1.

[0299] As can be seen from items F-1 to F-4 above, the relaxed implementation conditions may involve at least one of the following:

[0300] Relaxed TTT, relaxed signal quality threshold, relaxed position threshold.

[0301] It should be noted that "relaxed TTT" refers to a TTT that is less than the TTT used in the prior art, or a TTT that is less than a second threshold, which can be agreed upon in the protocol.

[0302] "Relaxed signal quality threshold" refers to a signal quality threshold that is lower than the signal quality threshold used in the prior art, or a signal quality threshold that is lower than a third threshold, which may be agreed upon by the protocol.

[0303] "Relaxed position threshold" refers to a position threshold that is less than the position threshold used in the prior art, or a position threshold that is less than a fourth threshold, which may be agreed upon by the protocol.

[0304] Optionally, the method further includes:

[0305] The terminal acquires third auxiliary information;

[0306] The third auxiliary information includes at least one of the following H-1 to H-15:

[0307] H-1 item: Third beam pattern information of at least one beam of at least one candidate cell; for example, third beam pattern information of at least one beam DRX configured in at least one candidate cell.

[0308] H-2: Coverage information associated with the third beam pattern information;

[0309] H-3: Beam identification information associated with the third beam pattern information;

[0310] H-4 item: Fourth beam pattern information for at least one region of at least one candidate cell;

[0311] H-5: Coverage information associated with the fourth beam pattern information;

[0312] H-6: Beam pattern information of the area covering the terminal in at least one candidate cell;

[0313] H-7 item: Beam pattern information of at least one candidate cell covering the terminal;

[0314] H-8 item: Third service time information of at least one beam of at least one candidate cell, such as the third service time information of at least one beam DRX configured in at least one candidate cell.

[0315] H-9: Coverage information associated with the third service time information;

[0316] H-10: Beam identification information associated with the third service time information;

[0317] H-11 item: Fourth service time information of the beam in at least one area of ​​at least one candidate cell;

[0318] H-12: Regional information associated with the fourth service time information;

[0319] H-13: Service time information of the beam covering the terminal in at least one candidate cell;

[0320] H-14: Service time information of the beam in at least one candidate cell covering the area of ​​the terminal;

[0321] H-15: Fifth indication information, used to indicate at least one of the following times: the first time, the second time, the third time, the fourth time, the fifth time, the sixth time, the seventh time, the eighth time, the fifteenth time, the sixteenth time, the seventeenth time, the eighteenth time, the nineteenth time, the twentieth time, the twenty-first time, and the twenty-second time.

[0322] The terminal can receive third auxiliary information sent by network-side devices.

[0323] In addition, after obtaining the third auxiliary information, the terminal can execute at least one of the following P-1 to P-2:

[0324] Item P-1: Determine at least one of the first candidate cell, the second candidate cell, and the third candidate cell based on the third auxiliary information;

[0325] Item P-2: Based on the third auxiliary information, determine the triggered cells that meet the first condition.

[0326] For item P-1, the third auxiliary information includes at least one of the relevant beam pattern information and the service time information of the beam of at least one candidate cell. Then, the terminal can select a cell that satisfies at least one of G-4 to G-15 from the candidate cells indicated by the third auxiliary information based on the contents included in the third auxiliary information. Therefore, the terminal can determine at least one of the first candidate cell, the second candidate cell and the third candidate cell based on the third auxiliary information.

[0327] It is understandable that the process of selecting cells that meet at least one of the above G-4 to G-15 based on the third auxiliary information can be referred to in the previous section on determining whether the terminal meets the second condition based on at least one of the first and second auxiliary information, which will not be repeated here.

[0328] For item P-2, the third auxiliary information includes at least one of the relevant beam pattern information and the service time information of the beam of at least one candidate cell. If the third auxiliary information includes at least one of the relevant beam pattern information and the service time information of the beam of the triggered cell, the terminal can select the triggered cell that meets the first condition from the triggered cells based on the information of the triggered cell.

[0329] It is understandable that the process of selecting the triggered cell that meets the first condition based on the third auxiliary information can be referred to in the previous section on the process of determining whether the terminal meets the second condition based on at least one of the first and second auxiliary information, which will not be repeated here.

[0330] Optionally, at least one of the first auxiliary information, the second auxiliary information, and the third auxiliary information is carried in at least one of the following:

[0331] System message;

[0332] Send a Radio Resource Control (RRC) reconfiguration message containing conditional switching configuration information;

[0333] Send an RRC reconfiguration message after the condition switching configuration information is sent;

[0334] Send a Physical Layer L1 or Data Link Layer L2 indication message after sending the condition switching configuration information.

[0335] It should be noted that when the second auxiliary information is carried in the RRC reconfiguration message that sends the condition handover configuration information, the second auxiliary information is associated with the configuration of each candidate cell.

[0336] In addition, it should be noted that "greater than" in this article can be replaced with "greater than or equal to"; "less than" can also be replaced with "less than or equal to"; and which execution scheme to choose in the specific case of "equal to" can be determined according to the actual situation.

[0337] Embodiments of this application also provide a cell handover method, see [link to relevant documentation]. Figure 5 The method may include the following steps:

[0338] Step 501: The network-side device sends at least one of the following:

[0339] First auxiliary information, the first auxiliary information is used to indicate the beam pattern information of the serving cell of the terminal;

[0340] Second auxiliary information, which is used to indicate the service time information of the serving cell of the terminal;

[0341] The third auxiliary information is used to indicate at least one of the following: beam pattern information of at least one candidate cell, and service time information of at least one candidate cell.

[0342] Among them, at least one of the first auxiliary information, the second auxiliary information, and the third auxiliary information is used by the terminal to perform cell handover so that the cell can be switched to a suitable cell in a timely manner to avoid service interruption.

[0343] It is understood that the specific contents of the first, second, and third auxiliary information mentioned here can be found in the previous text, and will not be repeated here.

[0344] Furthermore, the relevant instructions on the use of at least one of the first auxiliary information, the second auxiliary information, and the third auxiliary information for cell handover can be found above and will not be repeated here.

[0345] Optionally, the method further includes:

[0346] The network-side device sends at least one of the following:

[0347] Relaxed implementation conditions;

[0348] The fourth indication information is used to instruct the terminal to determine whether the terminal meets the second condition.

[0349] Optionally, at least one of the first auxiliary information, the second auxiliary information, and the third auxiliary information is carried in at least one of the following:

[0350] System message;

[0351] Send a Radio Resource Control (RRC) reconfiguration message containing conditional switching configuration information;

[0352] Send an RRC reconfiguration message after the condition switching configuration information is sent;

[0353] Send a Physical Layer L1 or Data Link Layer L2 indication message after sending the condition switching configuration information.

[0354] The process of network-side devices sending conditional switching configuration information, as well as at least one of the first auxiliary information, second auxiliary information, and third auxiliary information, is explained below:

[0355] Network-side devices can send conditional handover configuration information, which includes the configuration of at least one candidate cell and the corresponding execution conditions in existing technologies (i.e., execution conditions in existing version protocols); optionally, the conditional handover configuration information also includes relaxed execution conditions.

[0356] Additionally, by way of example, the conditional switching configuration information can be carried in the RRC reconfiguration message, and at least one of the first auxiliary information, the second auxiliary information, and the third auxiliary information can be carried in at least one of the following: a system message, an RRC reconfiguration message after sending the conditional switching configuration information, or an L1 or L2 indication message after sending the conditional switching configuration information.

[0357] Alternatively, for example, at least one of the conditional switching configuration information, the first auxiliary information, the second auxiliary information, and the third auxiliary information can be carried in the RRC reconfiguration message; it should be noted that in this case, at least one of the first auxiliary information, the second auxiliary information, and the third auxiliary information may not be included in the conditional switching configuration information.

[0358] Alternatively, for example, the third auxiliary information may be included in the conditional handover configuration information, such as the conditional handover configuration information including at least one of the following contents of at least one candidate cell:

[0359] Community configuration;

[0360] The corresponding execution conditions in existing technologies;

[0361] The corresponding relaxed implementation conditions;

[0362] Beam pattern information for at least one beam in the cell;

[0363] Coverage information associated with the beam pattern information of at least one beam in the cell;

[0364] The beam pattern information of at least one beam in the cell is associated with the beam identification information;

[0365] Beam pattern information for at least one area of ​​the cell;

[0366] Coverage information associated with the beam pattern information of at least one area of ​​the cell;

[0367] Beam pattern information for the area covering the terminal in the cell;

[0368] Beam pattern information of the beams covering the terminals in the cell;

[0369] Service time information for at least one beam in the cell;

[0370] The coverage information associated with the service time information of at least one beam in the cell;

[0371] The service time information of at least one beam in the cell is associated with the beam identification information;

[0372] Service time information of the beam in at least one area of ​​the cell;

[0373] The service time information of the beam in at least one area of ​​the cell is associated with the area information;

[0374] Service time information of the beams covering the terminals in the community;

[0375] Service time information of the beam in the area of ​​the cell covering the terminal.

[0376] It is understandable that the conditional handover configuration information is carried in the RRC reconfiguration message. Therefore, when the third auxiliary information is included in the conditional handover configuration information, the third auxiliary information is carried in the RRC reconfiguration message.

[0377] It should be noted that the relevant explanations regarding the implementation conditions for relaxation and the second condition can be found in the preceding text, and will not be repeated here.

[0378] In addition, the specific processing procedure for the terminal to execute based on relaxed execution conditions and fourth instruction information can also be found in the previous text, and will not be repeated here.

[0379] The specific implementation methods of the cell handover method in this application can be described in the following embodiments one to four:

[0380] Implementation Method 1: The terminal performs mobility management based on beam pattern information, including the following steps 1 to 5:

[0381] Step 1: The terminal acquires the first auxiliary information;

[0382] Among them, the terminal can receive the first auxiliary information sent by the network-side device;

[0383] In addition, the first auxiliary information is used to indicate the beam pattern information of the serving cell of the terminal;

[0384] In addition, the content of the first auxiliary information may be described in the following cases one to three:

[0385] Scenario 1: The first auxiliary information includes the beam pattern information of all beams in the serving cell that are configured with at least one of beam DTX and beam DRX;

[0386] Scenario 2: The first auxiliary information includes beam pattern information for different areas of the serving cell;

[0387] Scenario 3: The first auxiliary information includes the beam pattern information of the beam / area covering the terminal;

[0388] Furthermore, in the above scenario one, the first auxiliary information may also optionally include: beam information associated with each beam pattern (i.e., beam identification information) and beam coverage information;

[0389] In the second scenario described above, the first auxiliary information may also optionally include: coverage information of the region associated with each beam pattern;

[0390] Furthermore, for Situations 1 and 2 above, the transmission and signaling method of the first auxiliary information can be any of the following:

[0391] System message.

[0392] Regarding scenario three above, the transmission of the first auxiliary information and its signaling method can be any of the following:

[0393] Send an RRC reconfiguration message containing condition switching configuration information;

[0394] The RRC reconfiguration message following the sending of condition switching configuration information;

[0395] After sending the condition switching configuration information, send the L1 / L2 indication information.

[0396] Step 2: The terminal determines the beam used by the terminal or the beam pattern information of the area it is located in, and then determines at least one of the following:

[0397] Whether the beam used by the terminal or the area it is located in has been configured / activated with at least one of beam DTX and beam DRX;

[0398] The beam used by the terminal or the beam status of the area where it is located;

[0399] The time it takes for the beam used by the terminal or the beam in the area it is in to turn off;

[0400] Specifically, for either situation one or two above: the terminal first determines the beam it uses or the area it is located in based on its geographical location; then, based on the beam pattern information of each beam provided in the first auxiliary information or the range information of the area associated with each beam pattern information, it determines the beam pattern information of the beam used by the terminal or the area it is located in; further, based on the beam state (on / off) determined by the beam pattern information, at least one of the following: the remaining time before the beam turns off.

[0401] For example, regarding scenario one:

[0402] Based on its location, the terminal first determines that the beam it is using is beam 1; then, if the first auxiliary information does not provide beam pattern information associated with beam 1, the terminal may assume that the beam it is using is not configured with at least one of beam DTX and beam DRX, or that the beam it is using is not activated with at least one of beam DTX and beam DRX.

[0403] If the first auxiliary information provides beam pattern information of the beam used by the terminal, the terminal can assume that the beam it uses is configured with at least one of beam DTX and beam DRX, or that the beam used by the terminal is activated with at least one of beam DTX and beam DRX. In this way, the terminal determines the beam state (on / off) of the beam used by the terminal based on the beam pattern information, and at least one of the remaining time of transitioning to off.

[0404] Alternatively, it can be understood as follows: In Case 1, the first auxiliary information provides beam pattern information for all beams in the service cell that are configured with at least one of beam DTX and beam DRX, as well as the identification information of the beam and the beam coverage information associated with the beam pattern information. Thus, if the first auxiliary information contains beam coverage information covering the location of the terminal, the beam associated with the beam coverage information is the beam used by the terminal. If the first auxiliary information provides beam pattern information of the beam used by the terminal, the terminal can assume that the beam it uses is configured with at least one of beam DTX and beam DRX, or that the beam used by the terminal has activated at least one of beam DTX and beam DRX.

[0405] Regarding the second scenario above:

[0406] Based on its location, the terminal first determines that the coverage area of ​​its location is coverage area 1 (i.e., the terminal is within coverage area 1); then, if the first auxiliary information does not provide beam pattern information associated with coverage area 1, the terminal may assume that its location is not configured with at least one of beam DTX and beam DRX, or that the location of the terminal is not activated with at least one of beam DTX and beam DRX.

[0407] If the first auxiliary information provides beam pattern information associated with coverage area 1, the terminal can assume that its area is configured with at least one of beam DTX and beam DRX, or that the area where the terminal is located is activated with at least one of beam DTX and beam DRX. In this way, the terminal determines the beam state (on / off) of the beam in its area based on the beam pattern information, and at least one of the remaining time before it turns off.

[0408] Regarding situation three above:

[0409] As a first example: the network-side device will only provide the beam pattern information of the area where the terminal is located or the beam used, based on the terminal's location information;

[0410] Thus, if the terminal receives beam pattern information, the terminal believes that the beam it uses or the area it is in is configured with at least one of beam DTX and beam DRX, or that the beam it uses or the area it is in is activated with at least one of beam DTX and beam DRX; and can determine the beam state (on / off) of the beam used by the terminal based on the beam pattern information, and at least one of the remaining time before it turns off.

[0411] If the terminal does not receive beam pattern information, it implies that: the beam used or the area it is in has not been configured with at least one of beam DTX and beam DRX, or the beam used or the area it is in has not been activated with at least one of beam DTX and beam DRX.

[0412] As a second example, the network-side device can configure information based on the terminal's location information to indicate whether the beam used by the terminal or the area it is in has been configured / activated with at least one of beam DTX and beam DRX.

[0413] It should be noted that step 2 here can be performed periodically, or triggered by an instruction sent by the network-side device, or performed by the terminal after it determines that it has moved.

[0414] Furthermore, through step 2 above, if the terminal satisfies at least one of the following conditions, then the terminal executes step 3a or 3b as follows:

[0415] The beam used by the terminal or the area it is located in has been configured or activated with at least one of beam DTX and beam DRX;

[0416] The beam used by the terminal or the beam status of the area it is in is off;

[0417] The beam used by the terminal or the beam status of the area it is in will change to off before T1.

[0418] Step 3a: The terminal uses relaxed execution conditions to evaluate the conditions of the first candidate cell, thereby determining the cell that meets the relaxed execution conditions as the triggered cell;

[0419] The relaxed implementation conditions may include at least one of the following:

[0420] An execution condition with a TTT of 0 means that when the terminal evaluates the execution conditions of the first candidate cell, it evaluates the execution conditions with a TTT of 0. For example, the network configures the execution condition 1 of candidate cell 1 with a TTT of 2ms, but in this case, the terminal evaluates the execution condition 1 of candidate cell 1 with a TTT of 0.

[0421] Relaxing at least one of the signal quality threshold and the location threshold, that is, when the terminal evaluates the execution conditions of the first candidate cell, it relaxes its RSRP threshold or relaxes its location threshold; for example, the execution condition 1 configured by the network side device for candidate cell 1 is an A4 event, and its RSRP threshold is 2dB, but in the case of step 3a, the terminal evaluates the execution conditions of candidate cell 1 according to the threshold of 1dB.

[0422] The network-side device configures relaxed execution conditions, which are used by the terminal to evaluate the first candidate cell. Before this, the terminal can obtain the relaxed execution conditions configured by the network-side device. For example, the network-side device configures execution condition 1-1 and relaxed execution condition 1-2 for candidate cell 1. Before step 2, the terminal uses execution condition 1-1 to evaluate candidate cell 1. However, after step 2, when the above conditions are met, the terminal stops using execution condition 1-1 and starts using execution condition 1-2 to evaluate candidate cell 1.

[0423] Optionally, in step 3a, the terminal uses relaxed execution conditions to evaluate the first candidate cell. If the evaluation finds that only one execution condition is met, the cell can be considered as the triggered cell, and a handover for the cell can be initiated. For example, in this mode, if the terminal is configured with candidate cell 1 and candidate cell 2, where candidate cell 1 is configured with execution conditions 1-1 and 1-2, and candidate cell 2 is configured with execution conditions 2-1 and 2-2, when the terminal evaluates and finds that execution condition 1-1 of candidate cell 1 is met, but execution condition 1-2 is not met, the terminal initiates a handover for candidate cell 1.

[0424] It should also be noted that the value of T1 is greater than or equal to 0. T1 can be obtained by the terminal from the network-side device, or it can be determined by the terminal itself based on its implementation.

[0425] In addition, the first candidate cell can satisfy at least one of the following:

[0426] The first candidate cell was not configured with at least one of beam DTX and beam DRX;

[0427] The first candidate cell has not activated at least one of beam DTX and beam DRX;

[0428] The beam of the terminal covered by the first candidate cell is not configured with at least one of beam DTX and beam DRX;

[0429] The beam of the terminal covered by the first candidate cell is not activated, at least one of beam DTX and beam DRX;

[0430] The beam of the first candidate cell covering the terminal is configured with at least one of beam DTX and beam DRX, but it is in beam on.

[0431] The time for the beam of the terminal covered by the first candidate cell to switch to the deactivated state is greater than T3;

[0432] The remaining service time of the beam covering the terminal in the first candidate cell is greater than T4;

[0433] The area covered by the terminal in the first candidate cell is not configured with at least one of beam DTX and beam DRX.

[0434] The area covered by the terminal in the first candidate cell has not activated at least one of beam DTX and beam DRX;

[0435] The area of ​​the terminal covered by the first candidate cell is configured with at least one of beam DTX and beam DRX, but its beam is on.

[0436] The time for the beam state of the area covered by the first candidate cell to change to the deactivated state is greater than T3;

[0437] The remaining service time of the beam in the area covered by the first candidate cell of the terminal is greater than T4;

[0438] The first candidate cell is a candidate cell configured by the network-side equipment for the terminal.

[0439] Step 3b: The terminal selects the second candidate cell as the cell to be triggered.

[0440] The second candidate cell satisfies at least one of the following:

[0441] The second candidate cell meets the execution conditions; (wherein, the execution conditions can be relaxed or non-relaxed.)

[0442] Among the candidate cells configured for the terminal by the network-side equipment, the second candidate cell has the best signal quality;

[0443] Among the candidate cells configured for the terminal by the network-side device, the second candidate cell is closest to the terminal;

[0444] The second candidate cell was not configured with at least one of beam DTX and beam DRX;

[0445] The second candidate cell has not activated at least one of beam DTX and beam DRX;

[0454] The time for the beam state of the area covered by the second candidate cell to change to the deactivated state is greater than T3;

[0455] The remaining service time of the beam in the area covered by the second candidate cell for the terminal is greater than T4;

[0456] The second candidate cell is a candidate cell configured by the network-side equipment for the terminal.

[0457] Step 4: The terminal determines the target cell among the triggered cells;

[0458] Step 5: The terminal switches to the target cell.

[0459] Implementation Method 2: The terminal performs mobility management based on the service time information of the beam, including the following steps 1 to 5:

[0460] Step 1: The terminal acquires the second auxiliary information;

[0461] The terminal can receive second auxiliary information sent by the network-side device;

[0462] In addition, the second auxiliary information is used to indicate the service time information of the serving cell;

[0463] In addition, the second auxiliary information may include the content described in cases one to three as follows:

[0464] Scenario 1: The second auxiliary information includes: service time information of the beam in at least one area of ​​the serving cell, and area information associated with the service time information;

[0465] Scenario 2: The second auxiliary information includes: service time information of at least one beam of the serving cell, beam information associated with the service time information (i.e. beam identification information), and beam coverage information;

[0466] Scenario 3: The second auxiliary information includes the service time information of the beam used by the terminal, or the service time information of the beam in the area where the terminal is located;

[0467] Furthermore, the transmission and signaling method of the second auxiliary information can be any of the following:

[0468] Send an RRC reconfiguration message containing condition switching configuration information;

[0469] The RRC reconfiguration message following the sending of condition switching configuration information;

[0470] After sending the condition switching configuration information, send the L1 / L2 indication information;

[0471] System message.

[0472] It should be noted that when the second auxiliary information is carried in the RRC reconfiguration message that sends the condition handover configuration information, the second auxiliary information is associated with the configuration of each candidate cell.

[0473] Step 2: The terminal determines whether the beam it is using or the area it is located in has been configured with service time information, and then determines at least one of the following:

[0474] Whether the beam used by the terminal or the area it is located in has been configured / activated with at least one of beam DTX and beam DRX;

[0475] Service time information of the beam used by the terminal or the beam in the area where it is located;

[0476] The remaining service time of the beam used by the terminal or the beam in the area where it is located.

[0477] Specifically, for the above situation one: the terminal first determines its location based on its geographical location; then the terminal determines the service time information of the beam in the area where the terminal is located based on the service time information of the beam of at least one area of ​​the serving cell provided in the second auxiliary information and the associated area information; optionally, if the terminal's location is not in the area associated with the service time information in the second auxiliary information, it can be considered that the area where the terminal is located has not been configured or activated with at least one of beamDTX and beam DRX.

[0478] For example, the second auxiliary information provides service time information 1 for region 1 and service time information 2 for region 2. The terminal determines that it is in region 1 based on its location, and then the terminal can determine its service time based on service time information 1. For example, if service time information 1 is 10:00:00 on August 2, 2024 (e.g., Coordinated Universal Time (UTC)), and the time is 8:00:00 on August 2, 2024, then the terminal determines at least one of the following: the service deadline is 10:00:00 on August 2, 2024, and the remaining service time is 2 hours and 00 minutes.

[0479] Regarding the above scenario two: The terminal first determines the beam it uses based on its geographical location; then, based on the service time information of at least one beam of the serving cell provided in the second auxiliary information, as well as the identification information and coverage information of the associated beam, it determines the service time information associated with the beam used by the terminal; optionally, if the terminal's location is not within the coverage area of ​​the beam associated with the service time information provided in the second auxiliary information, it can be considered that the beam used by the terminal has not been configured or activated for at least one of beam DTX and beam DRX.

[0480] For example, the second auxiliary information provides beam 1 and its associated service time information 1 and coverage area 1, beam 2 and its associated service time information 2 and coverage area 2. The terminal determines that it is within the coverage area of ​​beam 1 based on its location, that is, it determines that its service beam is beam 1. Furthermore, the terminal can determine that its beam service time information is service time information 1. For example, if service time information 1 is 10:00:00 on August 2, 2024 (e.g., UTC time), and the time is 8:00:00 on August 2, 2024, then the terminal determines at least one of the following: the service end time is 10:00:00 on August 2, 2024, and the remaining service time is 2 hours 00 minutes 00 seconds.

[0481] Regarding scenario three above: The network-side device can provide only the service time information of the beam in the area where the terminal is located, or the service time information of the beam in which the terminal is located, based on the terminal's location information. In this way, if the terminal receives the service time information, the terminal believes that the beam it is using or the area it is in is configured with at least one of beam DTX and beam DRX, or that the beam it is using or the area it is in is activated with at least one of beam DTX and beam DRX. The terminal can determine the service time or remaining service time of the beam it is using or the area it is in based on the service time information.

[0482] If the terminal does not receive service time information, it implies that: the beam used or the area it is in is not configured with at least one of beam DTX or beam DRX, or the beam used or the area it is in is not activated with at least one of beam DTX or beam DRX.

[0483] It should be noted that step 2 here can be performed periodically, or triggered by an instruction sent by the network-side device, or performed by the terminal after it determines that it has moved.

[0484] Furthermore, through step 2 above, if the terminal satisfies at least one of the following conditions, then the terminal executes step 3a or 3b as follows:

[0485] The beam used by the terminal or the area it is located in has been configured or activated with at least one of beam DTX and beam DRX;

[0486] Determine that the service time of the beam used by the terminal or the beam in the area where it is located expires before T2.

[0487] Step 3a: The terminal uses relaxed execution conditions to evaluate the conditions of the first candidate cell, thereby determining the cell that meets the relaxed execution conditions as the triggered cell;

[0488] The relaxed implementation conditions may include at least one of the following:

[0489] The execution condition with a TTT of 0 means that when the terminal evaluates the execution conditions of the first candidate cell, it evaluates the execution conditions with a TTT of 0. For example, the network configures the execution condition 1 of candidate cell 1 with a TTT of 2ms, but in this case, the UE evaluates the execution condition 1 of candidate cell 1 with a TTT of 0.

[0490] Relaxing at least one of the signal quality threshold and the location threshold, that is, when the terminal evaluates the execution conditions of the first candidate cell, it relaxes its RSRP threshold or relaxes its location threshold; for example, the execution condition 1 configured by the network side device for candidate cell 1 is an A4 event, and its RSRP threshold is 2dB, but in the case of step 3a, the terminal evaluates the execution conditions of candidate cell 1 according to the threshold of 1dB.

[0491] The network-side device configures relaxed execution conditions, which are used by the terminal to evaluate the first candidate cell. Before this, the terminal can obtain the relaxed execution conditions configured by the network-side device. For example, the network-side device configures execution condition 1-1 and relaxed execution condition 1-2 for candidate cell 1. Before step 2, the terminal uses execution condition 1-1 to evaluate candidate cell 1. However, after step 2, when the above conditions are met, the terminal stops using execution condition 1-1 and starts using execution condition 1-2 to evaluate candidate cell 1.

[0492] Optionally, in step 3a, the terminal uses relaxed execution conditions to evaluate the first candidate cell. If the evaluation finds that only one execution condition is met, the cell can be considered as the triggered cell, and a handover for the cell can be initiated. For example, in this mode, if the terminal is configured with candidate cell 1 and candidate cell 2, where candidate cell 1 is configured with execution conditions 1-1 and 1-2, and candidate cell 2 is configured with execution conditions 2-1 and 2-2, when the terminal evaluates and finds that execution condition 1-1 of candidate cell 1 is met, but execution condition 1-2 is not met, the terminal initiates a handover for candidate cell 1.

[0493] It should also be noted that the value of T2 is greater than or equal to 0. T2 can be obtained by the terminal from the network-side device, or it can be determined by the terminal itself based on its implementation.

[0494] In addition, the first candidate cell can satisfy at least one of the following:

[0495] The first candidate cell was not configured with at least one of beam DTX and beam DRX;

[0496] The first candidate cell has not activated at least one of beam DTX and beam DRX;

[0497] The beam of the terminal covered by the first candidate cell is not configured with at least one of beam DTX and beam DRX;

[0500] The time for the beam of the terminal covered by the first candidate cell to switch to the deactivated state is greater than T3;

[0501] The remaining service time of the beam covering the terminal in the first candidate cell is greater than T4;

[0502] The area covered by the terminal in the first candidate cell is not configured with at least one of beam DTX and beam DRX.

[0503] The area covered by the terminal in the first candidate cell has not activated at least one of beam DTX and beam DRX;

[0504] The area of ​​the terminal covered by the first candidate cell is configured with at least one of beam DTX and beam DRX, but its beam is on.

[0505] The time for the beam state of the area covered by the first candidate cell to change to the deactivated state is greater than T3;

[0506] The remaining service time of the beam in the area covered by the first candidate cell of the terminal is greater than T4;

[0507] The first candidate cell is a candidate cell configured by the network-side equipment for the terminal.

[0508] Step 3b: The terminal selects the second candidate cell as the cell to be triggered.

[0509] The second candidate cell satisfies at least one of the following:

[0510] The second candidate cell meets the execution conditions; (wherein, the execution conditions can be relaxed or non-relaxed.)

[0511] Among the candidate cells configured for the terminal by the network-side equipment, the second candidate cell has the best signal quality;

[0512] Among the candidate cells configured for the terminal by the network-side device, the second candidate cell is closest to the terminal;

[0513] The second candidate cell was not configured with at least one of beam DTX and beam DRX;

[0518] The time for the beam of the terminal covered by the second candidate cell to switch to the deactivated state is greater than T3;

[0519] The remaining service time of the beam covering the terminal in the second candidate cell is greater than T4;

[0520] The area covered by the terminal in the second candidate cell is not configured with at least one of beam DTX and beam DRX.

[0521] The area covered by the second candidate cell does not have at least one of beam DTX and beam DRX activated;

[0523] The time for the beam state of the area covered by the second candidate cell to change to the deactivated state is greater than T3;

[0524] The remaining service time of the beam in the area covered by the second candidate cell for the terminal is greater than T4;

[0525] The second candidate cell is a candidate cell configured by the network-side equipment for the terminal.

[0526] Step 4: The terminal determines the target cell among the triggered cells;

[0527] Step 5: The terminal switches to the target cell.

[0528] Implementation Method 3: The terminal evaluates only a portion of the candidate cells, specifically including the following steps 1 to 3:

[0529] Step 1: The terminal acquires third-party auxiliary information;

[0530] Among them, the terminal can receive third auxiliary information sent by network-side devices;

[0531] In addition, the third auxiliary information includes at least one of the following: beam pattern information of at least one candidate cell and beam service time information.

[0532] The beam pattern information and beam service time information can be provided in at least one of the following ways:

[0546] Step 2: The terminal receives conditional handover configuration information, and based on the conditional handover configuration information, determines at least one of the following through the aforementioned third auxiliary information:

[0547] Whether each candidate cell has been configured / activated with at least one of beam DTX and beam DRX;

[0548] The beam status of each candidate cell;

[0549] Information on the remaining service time of each candidate cell's beam.

[0550] It is understood that the specific determination process of step 2 here can be found in the specific determination process of step 2 in the above-described embodiments one and two, and will not be repeated here.

[0551] It should be noted that step 2 here can be performed periodically, or triggered by an instruction sent by the network-side device, or performed by the terminal after it determines that it has moved.

[0552] Step 3: The terminal executes at least one of the following:

[0553] If the candidate cell has not been configured / activated with at least one of beam DTX and beam DRX, the terminal performs a conditional evaluation on the candidate cell.

[0554] When the beam pattern of the candidate cell is on, the terminal performs condition evaluation on the candidate cell;

[0555] If the time for the beam to switch to beam off in the candidate cell is greater than T3, the terminal performs a conditional evaluation on the candidate cell.

[0556] If the remaining service time of the beam of the candidate cell is greater than T4, the terminal performs a conditional evaluation on the candidate cell.

[0557] Otherwise, the terminal will not perform condition evaluation on the candidate cells.

[0558] Implementation Method 4: The terminal selects the target cell for handover based on the beam pattern information or beam service time information of the candidate cells, specifically including the following steps 1 to 4:

[0560] Among them, the terminal can receive third auxiliary information sent by network-side devices;

[0561] In addition, the third auxiliary information includes at least one of the following: beam pattern information of at least one candidate cell and beam service time information.

[0562] The beam pattern information and beam service time information can be provided in at least one of the following ways:

[0563] After the serving cell interacts with the candidate cell to obtain the information, it is sent to the terminal in the RRC reconfiguration message carried by the serving cell.

[0564] Retrieved from the broadcast message;

[0566] In addition, the beam pattern information of the candidate cell may include at least one of the following:

[0576] Step 2: The terminal performs a handover assessment, evaluating and determining several candidate cells that meet the execution conditions as the cells to be triggered;

[0577] or,

[0578] Based on the implementation method one or two described above, the terminal should directly select the second candidate cell as the cell to be triggered.

[0583] It is understood that the specific determination process of step 3 here can be found in the specific determination process of step 2 in the above-described embodiments one and two, and will not be repeated here.

[0584] It should be noted that step 3 here can be performed periodically, or triggered by an instruction sent by the network-side device, or performed by the terminal after it determines that it has moved.

[0585] Step 4: The terminal executes at least one of the following:

[0586] If the triggered cell has not been configured / activated with at least one of beam DTX and beam DRX, the terminal selects the triggered cell as the target cell.

[0587] When the beam pattern of the triggered cell is on, the terminal can select the triggered cell as the target cell;

[0588] If the time for the beam to switch to beam off in the triggered cell is greater than T3, the terminal may select the triggered cell as the target cell.

[0589] If the remaining service time of the beam in the triggered cell is greater than T4, the terminal may select the triggered cell as the target cell.

[0590] Otherwise, the terminal will not select the triggered cell as the target cell.

[0591] Furthermore, the following examples illustrate the combinations of the above-described embodiments one through four:

[0592] As a first example, any of the above-described implementation methods one or two can be combined with implementation method three. That is, the terminal decides whether to use relaxed execution conditions based on the beam pattern information or beam service time information of the serving cell. When using relaxed execution conditions, only the candidate cells determined in implementation method three are evaluated based on the relaxed execution conditions. When using non-relaxed execution conditions, only the candidate cells determined in implementation method three are evaluated based on the non-relaxed execution conditions. Thus, the cell that meets the execution conditions is determined as the triggered cell. Then, the target cell is determined among the triggered cells, and the terminal switches to the target cell.

[0593] As a second example, any of the above-described embodiments one or two can be combined with embodiment four. That is, the terminal decides whether to use relaxed execution conditions based on the beam pattern information or beam service time information of the serving cell, and then evaluates based on the decision result. When the evaluation finds that there are multiple triggered cells, the target cell is determined according to the method in embodiment four. Alternatively, the terminal decides to select the above-described second candidate cell as the triggered cell based on the beam pattern information or beam service time information of the serving cell, and when there are multiple triggered cells, the target cell is determined according to the method in embodiment four.

[0594] As a third example, any of the above-described implementation methods one or two can be combined with implementation methods three and four. That is, the terminal decides whether to use relaxed execution conditions based on the beam pattern information or beam service time information of the serving cell. When using relaxed execution conditions, only the candidate cells determined in implementation method three are evaluated based on the relaxed execution conditions; when using non-relaxed execution conditions, only the candidate cells determined in implementation method three are evaluated based on the non-relaxed execution conditions. Thus, the cell that meets the execution conditions is determined as the triggered cell. Furthermore, when there are multiple triggered cells, the target cell is determined according to the method in implementation method four.
