Description

Technical Field

[0001] This application relates to the field of mobile communication technology, and in particular to a network cell handover method, apparatus, computer equipment, and storage medium. Background Technology

[0002] The "low-altitude economy" is gaining momentum. It demonstrates tremendous vitality and demand in various fields, including power line inspection, logistics and distribution, emergency rescue, sports and entertainment, education and training, and urban transportation. With the continuous development of aircraft technology (such as drones), more and more aircraft are being widely used in numerous areas of production and daily life. As the application areas and business models of aircraft continue to expand, the need for aircraft to access mobile communication networks is becoming increasingly urgent.

[0003] In the current network architecture, the terrestrial network provides network coverage and services to both ground users and low-altitude users. Due to fewer building obstructions, the propagation attenuation of wireless signals in the air is relatively small. Aircraft at low altitudes (such as drones) can receive wireless signals radiated into the air through the side lobes of the ground cell antenna. This can cause low-altitude aircraft to frequently trigger network switching, leading to wireless link interruptions and the occupation of communication resources. Summary of the Invention

[0004] Therefore, it is necessary to provide a network cell handover method, apparatus, computer equipment, and storage medium that can prevent communication resources from being occupied due to frequent network switching terminals, in order to address the above-mentioned technical problems.

[0019] In one embodiment, the signal strength threshold value corresponding to the first initial beam is less than the signal strength threshold value corresponding to the second initial beam; wherein, the first initial beam is the initial beam among the initial beams that has the same beam coverage range as the current beam; and the second initial beam is the initial beam among the initial beams that has a different beam coverage range than the current beam.

[0020] Secondly, this application also provides a beamforming device. The device includes:

[0021] The acquisition module is used to acquire the beam signal strength corresponding to each initial beam after detecting a cell handover event for the terminal, wherein each initial beam is a beam adjacent to the current beam accessed by the terminal.

[0022] The selection module is used to select at least one candidate beam from each initial beam according to the beam signal strength and signal strength threshold value corresponding to each initial beam; wherein, the signal strength threshold value corresponding to each initial beam is related to the beam coverage area corresponding to the initial beam;

[0023] The determination module is used to determine the target beam that the terminal needs to access from each candidate beam according to the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, so as to switch the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam.

[0024] Thirdly, this application also provides a computer device. The computer device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to perform the following steps:

[0025] After detecting a cell handover event for the terminal, the beam signal strength corresponding to each initial beam is obtained, wherein each initial beam is a beam adjacent to the current beam accessed by the terminal.

[0026] Based on the beam signal strength and signal strength threshold value corresponding to each initial beam, at least one candidate beam is selected from each initial beam; wherein, the signal strength threshold value corresponding to each initial beam is related to the beam coverage area corresponding to the initial beam;

[0027] Based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, the target beam that the terminal needs to access is determined from each candidate beam, so as to switch the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam.

[0028] Fourthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, performs the following steps:

[0036] The aforementioned network cell handover method, apparatus, computer equipment, and storage medium acquire the beam signal strength corresponding to each initial beam to select at least one candidate beam from each initial beam based on the beam signal strength and signal strength threshold value. Then, based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, the target beam that the terminal needs to access is determined from each candidate beam to handover the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam. As described above, this application uses the beam signal strength corresponding to each initial beam and the signal strength threshold value corresponding to each initial beam to determine the threshold value for the beam signal strength of each initial beam. Then, initial beams with beam signal strength greater than the signal strength threshold value are used as candidate beams. This ensures that all candidate beams meet the beam signal strength requirements of the terminal, and that after the target beam is determined from the candidate beams, the target beam can effectively guarantee the stability of the terminal's access beam signal, preventing any impact on the terminal's communication quality. Furthermore, the target terminal is determined based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam. Therefore, by judging the relationship between the beam coverage areas of the two beams, the terminal can be switched from the current cell corresponding to the current beam to the target cell corresponding to the target beam based on the beam coverage range. This prevents the terminal from frequently switching networks, ensuring that communication resources are not occupied due to frequent network switching, and reducing the risk to the user's service performance.

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0048] The network cell handover method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or placed on a cloud or other network server. By acquiring the beam signal strength corresponding to each initial beam, at least one candidate beam is selected from each initial beam based on the beam signal strength and signal strength threshold value. Then, based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, the target beam that the terminal needs to access is determined from the candidate beams. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented using a standalone server or a server cluster composed of multiple servers.

[0049] In one embodiment, such as Figure 2 As shown, a network cell handover method is provided, which is applied to... Figure 1 Taking terminal 102 as an example, the explanation includes the following steps:

[0050] S201, after detecting a cell handover event for the terminal, obtain the beam signal strength corresponding to each initial beam.

[0051] Each initial beam is a beam adjacent to the current beam accessed by the terminal.

[0052] It should be noted that when it is necessary to obtain the beam signal strength corresponding to each initial beam, beam signal strength detection can be performed separately for each initial beam by pre-deploying beam detection equipment, or embedded software can be pre-deployed to monitor and record the beam signal strength in real time. Then, when it is necessary to obtain the beam signal strength corresponding to each initial beam, the operation of obtaining the beam signal strength corresponding to each initial beam can be performed based on the beam signal strength recorded by the embedded software.

[0053] To further explain, to ensure the successful determination of the target beam that the terminal needs to access, the communication beams can be pre-configured in layers to cover both air and ground. Specifically: the ground-to-ground beam covers ground users, the low-altitude beam covers low-altitude users, and the high-altitude beam covers high-altitude users; and independent beam indices are assigned to the initial beams of different layers of the air-to-ground base station. The initial beams may include: the ground-to-ground SSB (Synchronization Signal and PBCH block) beam, the low-altitude SSB beam, and the high-altitude SSB beam; for example... Figure 3 As shown, for air-to-ground base stations, three beams are allocated to the ground-level SSB beam, with beam indices 01, 02, and 03; two beams are allocated to the low-altitude SSB beam, with beam indices 04 and 05; and two beams are allocated to the high-altitude SSB beam, with beam indices 06 and 07. Figure 4 As shown, for ground-based base stations, SSB beam indices are assigned to ground-based base stations that are different from those for air-to-ground base stations, such as the assigned beam indices being 11, 12, 13, 14, 15, 16, and 17.

[0054] S202, select at least one candidate beam from each initial beam according to the beam signal strength and signal strength threshold value corresponding to each initial beam.

[0055] The signal strength threshold value corresponding to each initial beam is related to the beam coverage area of ​​the initial beam.

[0056] It should be noted that, in order to prevent terminals from frequently switching networks and to ensure that communication resources are not occupied due to frequent network switching, a signal strength threshold value can be set for each initial beam based on the beam coverage area corresponding to the initial beam, so as to limit the frequent switching of terminals within different beam coverage areas.

[0057] Specifically, a lower signal strength threshold is set for initial beams within the same beam coverage area, such as between low-altitude SSB beams or between ground-to-ground SSB beams; a higher signal strength threshold is set for communication beams within different beam coverage areas, such as between low-altitude and ground-to-ground SSB beams or between high-altitude and low-altitude SSB beams; specifically, the signal strength threshold corresponding to the first initial beam is lower than the signal strength threshold corresponding to the second initial beam; wherein, the first initial beam is the initial beam with the same beam coverage area as the current beam among all initial beams; and the second initial beam is the initial beam with a different beam coverage area than the current beam among all initial beams.

[0058] To further explain, when it is necessary to select at least one candidate beam from each initial beam based on the beam signal strength and signal strength threshold value corresponding to each initial beam, it can be determined whether there is an initial beam in each initial beam whose beam signal strength is greater than the signal strength threshold value of the initial beam. If so, the initial beam is taken as the candidate beam.

[0059] S203, based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, determine the target beam that the terminal needs to access from each candidate beam, so as to switch the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam.

[0060] It should be noted that when it is necessary to determine the target beam that the terminal needs to access from each candidate beam based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, it can be verified whether there is a case where the beam coverage area corresponding to each candidate beam is the same as the beam coverage area of ​​the current beam. If so, the candidate beam with the same beam coverage area as the current beam is taken as the target beam that the terminal needs to access.

[0061] The aforementioned network cell handover method obtains the beam signal strength corresponding to each initial beam to select at least one candidate beam from each initial beam based on the beam signal strength and signal strength threshold value. Then, based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, the target beam that the terminal needs to access is determined from each candidate beam to hand over the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam. As described above, this application uses the beam signal strength corresponding to each initial beam and the signal strength threshold value corresponding to each initial beam to determine the threshold value for the beam signal strength of each initial beam. Then, initial beams with beam signal strength greater than the signal strength threshold value are used as candidate beams. This ensures that all candidate beams meet the beam signal strength requirements of the terminal, and that after the target beam is determined from the candidate beams, the target beam can effectively guarantee the stability of the terminal's access beam signal, preventing any impact on the terminal's communication quality. Furthermore, the target terminal is determined based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam. Therefore, by judging the relationship between the beam coverage areas of the two beams, the terminal can be switched from the current cell corresponding to the current beam to the target cell corresponding to the target beam based on the beam coverage range. This prevents the terminal from frequently switching networks, ensuring that communication resources are not occupied due to frequent network switching, and reducing the risk to the user's service performance.

[0062] In one embodiment, such as Figure 5 As shown, when it is necessary to select at least one candidate beam from each initial beam based on the beam signal strength and signal strength threshold value corresponding to each initial beam, the following can be included:

[0063] S501, for each initial beam, based on the area identifier of the beam coverage area corresponding to the initial beam, search from the pre-built correspondence between area identifier and signal strength threshold value to obtain the signal strength threshold value corresponding to the initial beam.

[0064] In one embodiment of this application, when it is necessary to search from a pre-built correspondence between area identifiers and signal strength thresholds based on the area identifier of the beam coverage area corresponding to the initial beam, the following may be included: the correspondence between area identifiers and signal strength thresholds stores at least one area identifier and a signal strength threshold value corresponding to each area identifier; then, after determining the area identifier of the beam coverage area corresponding to the initial beam, the signal strength threshold value corresponding to the area identifier in the correspondence is determined to complete the operation of "searching from the pre-built correspondence between area identifiers and signal strength thresholds"; then, the signal strength threshold value corresponding to the area identifier in the correspondence is used as the signal strength threshold value corresponding to the initial beam.

[0065] S502, select at least one candidate beam from each initial beam according to the beam signal strength and signal strength threshold value corresponding to each initial beam.

[0066] It should be noted that when it is necessary to select at least one candidate beam from each initial beam based on the beam signal strength and signal strength threshold value corresponding to each initial beam, the following can be included: for each initial beam, if the beam signal strength of the initial beam is greater than the signal strength threshold value of the initial beam, the initial beam is used as a candidate beam.

[0067] In one embodiment of this application, if there are three initial beams, namely initial beam 1, initial beam 2 and initial beam 3, the beam signal strength of the three initial beams is compared with the corresponding signal strength threshold value. If the beam signal strength of initial beam 1 and initial beam 2 is greater than the signal strength threshold value of the initial beam, then initial beam 1 and initial beam 2 are selected as candidate beams.

[0068] The aforementioned network cell handover method obtains the signal strength threshold value corresponding to the initial beam from the pre-built correspondence between area identifiers and signal strength threshold values. This allows the initial beam with a signal strength greater than the initial beam's signal strength threshold value to be used as a candidate beam. This prevents the terminal from frequently switching networks based on the beam's coverage area, ensuring that communication resources are not occupied due to frequent network switching by the terminal, and reducing the risk to the user's service performance.

[0069] In one embodiment, such as Figure 6 As shown, when it is necessary to determine the target beam that the terminal needs to access from among the candidate beams based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, the following can be included:

[0070] S601, determine the regional relationship between the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam.

[0071] Regional relationships can include, but are not limited to: the same region, adjacent regions, and non-adjacent regions.

[0072] It should be noted that, in order to prevent the terminal from frequently switching networks in different beam coverage areas, it is possible to determine whether the regional relationship between the beam coverage area corresponding to a candidate beam and the beam coverage area of ​​the current beam is the same. If not, it is determined that the candidate beam is not the target beam; if so, it is determined that the candidate beam is the target beam.

[0073] S602 determines the target beam that the terminal needs to access from among the candidate beams based on the relationships between the regions.

[0074] Specifically, among the candidate beams, those with the same regional relationship as the current beam's coverage area are considered as candidate beams in the same region, and these are used as the target beams that the terminal needs to access.

[0075] In one embodiment of this application, such as Figure 7 As shown, when it is necessary to determine the target beam that the terminal needs to access, the specific steps may include the following: The terminal detects the beam signal strength corresponding to each initial beam and the beam index identifier corresponding to each initial beam, so as to feed back the beam signal strength corresponding to each initial beam and the beam index identifier corresponding to each initial beam to the server. The initial beams include: air-to-ground cell 2, ground-to-ground cell 3, and ground-to-ground cell 4; the current beam accessed by the terminal is ground-to-ground cell 1; the beam index information of the initial beam of air-to-ground cell 2 is 05, the beam index information of the initial beam of the adjacent ground-to-ground cell 3 is 16, and the beam index information of the initial beam of ground-to-ground cell 4 is 14; furthermore, the signal strength of the initial beam 05 of the adjacent air-to-ground cell 2 is greater than the low-altitude SSB beam handover threshold, and the signal strength of the adjacent ground-to-ground cell 3 is greater than the low-altitude SSB beam handover threshold. The initial beam 16 has a signal strength greater than the handover threshold between low-altitude and ground-to-ground SSBs, so adjacent air-to-ground cell 2 and adjacent ground-to-ground cell 3 are selected as candidate beams. The initial beam 14 of adjacent ground-to-ground cell 4 has a signal strength less than the handover threshold between low-altitude and ground-to-ground SSB beams, so it is not included in the target handover cell set. Furthermore, the beam index of the candidate beam of air-to-ground cell 1 is 04, which belongs to the low-altitude beam; the beam index of the candidate beam of adjacent air-to-ground cell 2 is 05, which belongs to the low-altitude beam; and the beam index of the candidate beam of adjacent ground-to-ground cell 3 is 16, which belongs to the ground-to-ground beam. Therefore, the network selects adjacent air-to-ground cell 2 as the target beam that the terminal needs to access.

[0076] The aforementioned network cell handover method determines the regional relationship between the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam. Based on this regional relationship, it identifies the target beam that the terminal needs to access from each candidate beam. By judging the relationship between the beam coverage areas of two beams, it prevents the terminal from frequently switching networks based on the beam coverage range, ensuring that communication resources are not occupied due to frequent network switching by the terminal, and reducing the risk to the user's service performance.

[0077] In one embodiment, such as Figure 8 As shown, when it is necessary to determine the target beam that the terminal needs to access, the following may be included:

[0078] S801, after detecting a cell handover event for the terminal, obtains the beam signal strength corresponding to each initial beam.

[0079] S802, for each initial beam, based on the area identifier of the beam coverage area corresponding to the initial beam, search from the pre-built correspondence between area identifier and signal strength threshold value to obtain the signal strength threshold value corresponding to the initial beam.

[0080] S803: For each initial beam, if the beam signal strength of the initial beam is greater than the signal strength threshold of the initial beam, the initial beam is selected as a candidate beam.

[0081] S804, determine the regional relationship between the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam.

[0082] S805 identifies candidate beams whose coverage area is the same as that of the current beam and uses them as the target beams that the terminal needs to access.

[0083] The aforementioned network cell handover method obtains the beam signal strength corresponding to each initial beam to select at least one candidate beam from each initial beam based on the beam signal strength and signal strength threshold value. Then, based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, the target beam that the terminal needs to access is determined from each candidate beam to hand over the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam. As described above, this application uses the beam signal strength corresponding to each initial beam and the signal strength threshold value corresponding to each initial beam to determine the threshold value for the beam signal strength of each initial beam. Then, initial beams with beam signal strength greater than the signal strength threshold value are used as candidate beams. This ensures that all candidate beams meet the beam signal strength requirements of the terminal, and that after the target beam is determined from the candidate beams, the target beam can effectively guarantee the stability of the terminal's access beam signal, preventing any impact on the terminal's communication quality. Furthermore, the target terminal is determined based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam. Therefore, by judging the relationship between the beam coverage areas of the two beams, the terminal can be switched from the current cell corresponding to the current beam to the target cell corresponding to the target beam based on the beam coverage range. This prevents the terminal from frequently switching networks, ensuring that communication resources are not occupied due to frequent network switching, and reducing the risk to the user's service performance.

[0084] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0085] Based on the same inventive concept, this application also provides a beam determination device for implementing the network cell handover method described above. The solution provided by this device is similar to the implementation described in the above method; therefore, the specific limitations in one or more beam determination device embodiments provided below can be found in the limitations of the network cell handover method described above, and will not be repeated here.

[0086] In one embodiment, such as Figure 9 As shown, a beamforming device is provided, comprising: an acquisition module 10, a selection module 20, and a determination module 30, wherein:

[0087] The acquisition module 10 is used to acquire the beam signal strength corresponding to each initial beam after detecting a cell handover event for the terminal, wherein each initial beam is a beam adjacent to the current beam accessed by the terminal.

[0088] Selection module 20 is used to select at least one candidate beam from each initial beam according to the beam signal strength and signal strength threshold value corresponding to each initial beam; wherein, the signal strength threshold value corresponding to each initial beam is related to the beam coverage area corresponding to the initial beam.

[0089] The determination module 30 is used to determine the target beam that the terminal needs to access from each candidate beam based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam.

[0090] In one embodiment, for each initial beam, the signal strength threshold value corresponding to the initial beam is obtained by searching from a pre-built correspondence between area identifiers and signal strength threshold values ​​based on the area identifier of the beam coverage area corresponding to the initial beam.

[0091] Based on the beam signal strength and signal strength threshold value corresponding to each initial beam, at least one candidate beam is selected from each initial beam.

[0092] In one embodiment, for each initial beam, if the beam signal strength of the initial beam is greater than a signal strength threshold of the initial beam, the initial beam is selected as a candidate beam.

[0093] In one embodiment, the regional relationship between the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam is determined respectively.

[0094] Based on the relationships between different regions, the target beam that the terminal needs to access is determined from among the candidate beams.

[0095] In one embodiment, candidate beams whose regional relationship with the current beam's coverage area is the same region are selected as the target beams that the terminal needs to access.

[0096] In one embodiment, the signal strength threshold value corresponding to the first initial beam is less than the signal strength threshold value corresponding to the second initial beam; wherein, the first initial beam is the initial beam among all initial beams that has the same beam coverage range as the current beam; and the second initial beam is the initial beam among all initial beams that has a different beam coverage range than the current beam.

[0097] The aforementioned network cell handover method obtains the beam signal strength corresponding to each initial beam to select at least one candidate beam from each initial beam based on the beam signal strength and signal strength threshold value. Then, based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam, the target beam that the terminal needs to access is determined from each candidate beam to hand over the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam. As described above, this application uses the beam signal strength corresponding to each initial beam and the signal strength threshold value corresponding to each initial beam to determine the threshold value for the beam signal strength of each initial beam. Then, initial beams with beam signal strength greater than the signal strength threshold value are used as candidate beams. This ensures that all candidate beams meet the beam signal strength requirements of the terminal, and that after the target beam is determined from the candidate beams, the target beam can effectively guarantee the stability of the terminal's access beam signal, preventing any impact on the terminal's communication quality. Furthermore, the target terminal is determined based on the beam coverage area corresponding to each candidate beam and the beam coverage area of ​​the current beam. Therefore, by judging the relationship between the beam coverage areas of the two beams, the terminal can be switched from the current cell corresponding to the current beam to the target cell corresponding to the target beam based on the beam coverage range. This prevents the terminal from frequently switching networks, ensuring that communication resources are not occupied due to frequent network switching, and reducing the risk to the user's service performance.
