The low-altitude economy has shown great vitality and demand in many fields such as line inspection, logistics distribution, emergency rescue, competitive entertainment, education and training, and urban transportation. With the continuous development of aircraft technology (such as drones), more and more aircraft are widely used in many fields of production and life. With the expansion of aircraft application fields and business models, the demand for aircraft to access mobile communication networks is becoming more and more urgent.
[0003] In the current networking architecture, the ground network provides network coverage and services for low-altitude users while covering ground users.

[0047] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0048] The network cell switching method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. By obtaining the beam signal strength corresponding to each initial beam, at least one candidate beam is selected from each initial beam according to the beam signal strength and signal strength threshold value corresponding to each initial beam, and then, according to 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. Among them, the terminal 102 can be but is not limited to various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.
[0049] In one embodiment, Figure 2 As shown, a network cell switching method is provided, and the method is applied to Figure 1 The terminal 102 in the example is used as an example to illustrate, and the following steps are included:
[0050] S201, after detecting a cell switching event for a terminal, obtaining beam signal strengths corresponding to each initial beam.
[0051] Among them, 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, the beam signal strength detection can be performed for each initial beam separately according to the pre-deployed beam detection equipment. Alternatively, embedded software can be pre-deployed to achieve real-time monitoring and recording of the beam signal strength. 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 implemented based on the beam signal strength recorded by the embedded software.
[0053] Further explanation: In order to ensure that the target beam that the terminal needs to access can be successfully determined later, the communication beams can be configured in layers in advance to cover the air and the ground respectively; specifically: the ground beam covers the ground users, the low-altitude beam covers the low-altitude users, and the high-altitude beam covers the high-altitude users; and the initial beams of different layers of the air-to-ground base station are assigned independent beam indexes; wherein the initial beams may include: the ground SSB (Synchronization Signal and PBCH block) beam, the low-altitude SSB beam and the high-altitude SSB beam; such as Figure 3 As shown, for the air-to-ground base station, three ground SSB beams are allocated, with beam indexes 01, 02, and 03; two low-altitude SSB beams are allocated, with beam indexes 04 and 05; and two high-altitude SSB beams are allocated, with beam indexes 06 and 07. Figure 4 As shown, for the ground base station, an SSB beam index different from that of the air-to-ground base station is allocated to the ground base station, such as the allocated beam indexes are 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 the signal strength threshold corresponding to each initial beam.
[0055] The signal strength threshold corresponding to each initial beam is related to the beam coverage area corresponding to the initial beam.
[0056] It should be noted that in order to prevent terminals from frequently switching networks and ensure that communication resources will not be occupied due to frequent network switching of terminals, a signal strength threshold value for different beam coverage ranges can be set for each initial beam according to the beam coverage area corresponding to the initial beam, so as to limit the frequent switching of terminals within different beam coverage ranges.
[0057] Among them, a lower signal strength threshold value is set for the initial beam within the same beam coverage range, for example, a lower signal strength threshold value is configured between low-altitude SSB beams and between ground-facing SSB beams; a higher signal strength threshold value is set for the communication beams within different beam coverage ranges, for example, a higher signal strength threshold value is configured between low-altitude and ground-facing SSB beams, and between high-altitude and low-altitude SSB beams; specifically, the signal strength threshold value corresponding to the first initial beam is smaller than the signal strength threshold value corresponding to the second initial beam; wherein the first initial beam is an initial beam among the initial beams having the same beam coverage range as the current beam; and the second initial beam is an initial beam among the initial beams having a different beam coverage range from the current beam.
[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 used as a candidate beam.
[0059] S203, according to 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 is possible to verify whether the beam coverage area corresponding to each candidate beam is the same as the beam coverage area of the current beam based on the beam coverage area corresponding to each candidate beam and the beam coverage area of the current beam. If so, the candidate beam with the same beam coverage area as the beam coverage area of the current beam will be used as the target beam that the terminal needs to access.
[0061] The above-mentioned network cell switching method obtains the beam signal strength corresponding to each initial beam to realize selecting at least one candidate beam from each initial beam according to the beam signal strength corresponding to each initial beam and the signal strength threshold value, and then, according to the beam coverage area corresponding to each candidate beam and the beam coverage area of the current beam, determines from each candidate beam the target beam that the terminal needs to access, so as to switch the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam. According to the above content, the present application realizes threshold value judgment for the beam signal strength corresponding to each initial beam through the beam signal strength corresponding to each initial beam and the signal strength threshold value corresponding to each initial beam, and then uses the initial beam whose beam signal strength is greater than the signal strength threshold value as a candidate beam; thereby ensuring that the candidate beams can meet the beam signal strength requirements of the terminal, and ensuring that after the target beam is subsequently determined from the candidate beams, the target beam can effectively ensure the stability of the terminal's access beam signal to prevent the terminal's communication quality from being affected, and 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, it is achieved that the terminal is switched from the current cell corresponding to the current beam to the target cell corresponding to the target beam according to the beam coverage range, preventing the terminal from frequently switching networks, ensuring that communication resources will not be occupied due to frequent network switching of the terminal, and reducing the user's service performance risk.
[0062] In one embodiment, if Figure 5 As shown, when it is necessary to select at least one candidate beam from each initial beam according to the beam signal strength and the signal strength threshold corresponding to each initial beam, the following contents may be specifically included:
[0063] S501 , for each initial beam, according to the area identifier of the beam coverage area corresponding to the initial beam, search from the pre-constructed correspondence between the area identifier and the signal strength threshold value to obtain the signal strength threshold value corresponding to the initial beam.
[0064] In one embodiment of the present application, when it is necessary to search from a pre-constructed correspondence between area identifiers and signal strength threshold values based on the area identifier of the beam coverage area corresponding to the initial beam, the following contents may be included: the correspondence between area identifiers and signal strength threshold values stores at least one area identifier and the signal strength threshold value corresponding to each area identifier, and then, after determining the area identifier of the beam coverage area corresponding to the initial beam, determine the signal strength threshold value corresponding to the area identifier in the correspondence relationship to complete the operation of "searching from a pre-constructed correspondence between area identifiers and signal strength threshold values", and then, use the signal strength threshold value corresponding to the area identifier in the correspondence relationship 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 corresponding to each initial beam and the signal strength threshold.
[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, it may specifically include the following contents: for each initial beam, when 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 the present application, if there are three initial beams in total, the three initial beams are initial beam 1, initial beam 2 and initial beam 3, respectively, the beam signal strengths of the three initial beams are compared with the corresponding signal strength threshold values, if the beam signal strengths of initial beam 1 and initial beam 2 are greater than the signal strength threshold values of the initial beams, initial beam 1 and initial beam 2 are used as candidate beams.
[0068] The above-mentioned network cell switching method obtains the signal strength threshold value corresponding to the initial beam from the correspondence between the pre-constructed area identifier and the signal strength threshold value, and then uses the initial beam whose beam signal strength is greater than the signal strength threshold value of the initial beam as a candidate beam. In this way, it is achieved according to the beam coverage range to prevent the terminal from frequently switching networks, ensures that communication resources will not be occupied due to frequent network switching of the terminal, and reduces the user's service performance risk.
[0069] In one embodiment, if Figure 6 As shown, when it is necessary 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, the following contents may be specifically included:
[0070] S601, respectively determine the area relationship between the beam coverage area corresponding to each candidate beam and the beam coverage area of the current beam.
[0071] The regional relationship may include but is 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 ranges, it is possible to determine whether the area relationship between the beam coverage area corresponding to a candidate beam and the beam coverage area of the current beam is the same area relationship. If not, it is determined that the candidate beam is not the target beam. If so, it can be determined that the candidate beam is the target beam.
[0073] S602: Determine a target beam that the terminal needs to access from candidate beams according to the relationship between the areas.
[0074] Specifically, among the candidate beams, the candidate beams whose area relationship with the beam coverage area of the current beam is the same area are used as the target beam that the terminal needs to access.
[0075] In one implementation of the present application, Figure 7 As shown, when it is necessary to determine the target beam that the terminal needs to access, the following contents may be specifically included: 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 realize the feedback of the beam signal strength corresponding to each initial beam, and the beam index identifier corresponding to each initial beam to the server, wherein the initial beam includes: ground-to-air cell 2, ground cell 3 and ground cell 4; the current beam accessed by the terminal is ground cell 1; the beam index information of the initial beam of the ground-to-air cell 2 is 05, the beam index information of the initial beam of the adjacent ground cell 3 is 16, and the beam index information of the initial beam of the ground cell 4 is 14; further, the signal strength of the initial beam 05 of the ground-to-air adjacent cell 2 is greater than the low-altitude SSB beam switching threshold, and the adjacent ground cell 3 The signal strength of the initial beam 16 of the resident ...
[0076] The above-mentioned network cell switching method determines the regional relationship between the beam coverage area corresponding to each candidate beam and the beam coverage area of the current beam, and determines the target beam that the terminal needs to access from each candidate beam according to the regional relationship. By judging the relationship between the beam coverage areas of the two beams, it is possible to prevent the terminal from frequently switching networks according to the beam coverage range, thereby ensuring that communication resources will not be occupied due to frequent network switching of the terminal, and reducing the user's service performance risk.
[0077] In one embodiment, if Figure 8 As shown, when it is necessary to determine the target beam that the terminal needs to access, the following contents may be specifically included:
[0078] S801: After a cell switching event for a terminal is detected, beam signal strengths corresponding to each initial beam are obtained.
[0079] S802: for each initial beam, according to the area identifier of the beam coverage area corresponding to the initial beam, search from the pre-constructed correspondence between the area identifier and the signal strength threshold value to obtain the signal strength threshold value corresponding to the initial beam.
[0080] S803: For each initial beam, when the beam signal strength of the initial beam is greater than the signal strength threshold of the initial beam, the initial beam is used as a candidate beam.
[0081] S804: Determine the area relationship between the beam coverage area corresponding to each candidate beam and the beam coverage area of the current beam.
[0082] S805: Among the candidate beams, the candidate beams whose area relationship with the beam coverage area of the current beam is the same area are used as the target beam that the terminal needs to access.
[0083] The above-mentioned network cell switching method obtains the beam signal strength corresponding to each initial beam to realize selecting at least one candidate beam from each initial beam according to the beam signal strength corresponding to each initial beam and the signal strength threshold value, and then, according to the beam coverage area corresponding to each candidate beam and the beam coverage area of the current beam, determines from each candidate beam the target beam that the terminal needs to access, so as to switch the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam. According to the above content, the present application realizes threshold value judgment for the beam signal strength corresponding to each initial beam through the beam signal strength corresponding to each initial beam and the signal strength threshold value corresponding to each initial beam, and then uses the initial beam whose beam signal strength is greater than the signal strength threshold value as a candidate beam; thereby ensuring that the candidate beams can meet the beam signal strength requirements of the terminal, and ensuring that after the target beam is subsequently determined from the candidate beams, the target beam can effectively ensure the stability of the terminal's access beam signal to prevent the terminal's communication quality from being affected, and 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, it is achieved that the terminal is switched from the current cell corresponding to the current beam to the target cell corresponding to the target beam according to the beam coverage range, preventing the terminal from frequently switching networks, ensuring that communication resources will not be occupied due to frequent network switching of the terminal, and reducing the user's service performance risk.
[0084] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
[0085] Based on the same inventive concept, the embodiment of the present application also provides a beam determination device for implementing the network cell switching method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more beam determination device embodiments provided below can refer to the limitations of the network cell switching method above, and will not be repeated here.
[0086] In one embodiment, Fig. 9 As shown, a beam determination 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 switching event for the terminal, wherein each initial beam is a beam adjacent to the current beam accessed by the terminal.
[0088] The selection module 20 is used to select at least one candidate beam from each initial beam according to the beam signal strength and the signal strength threshold corresponding to each initial beam; wherein the signal strength threshold 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 according to 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, according to the area identifier of the beam coverage area corresponding to the initial beam, a search is performed from a pre-constructed correspondence relationship between the area identifier and the signal strength threshold value to obtain the signal strength threshold value corresponding to the initial beam;
[0091] At least one candidate beam is selected from each initial beam according to the beam signal strength corresponding to each initial beam and the signal strength threshold.
[0092] In one embodiment, for each initial beam, when the beam signal strength of the initial beam is greater than a signal strength threshold of the initial beam, the initial beam is used as a candidate beam.
[0093] In one embodiment, the area relationship between the beam coverage area corresponding to each candidate beam and the beam coverage area of the current beam is determined respectively;
[0094] According to the relationship between each area, the target beam that the terminal needs to access is determined from each candidate beam.
[0095] In one embodiment, among the candidate beams, the candidate beams whose area relationship with the beam coverage area of the current beam is the same area are used as the target beam 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 an initial beam among the initial beams having the same beam coverage range as the current beam; and the second initial beam is an initial beam among the initial beams having a different beam coverage range from the current beam.
[0097] The above-mentioned network cell switching method obtains the beam signal strength corresponding to each initial beam to realize selecting at least one candidate beam from each initial beam according to the beam signal strength corresponding to each initial beam and the signal strength threshold value, and then, according to the beam coverage area corresponding to each candidate beam and the beam coverage area of the current beam, determines from each candidate beam the target beam that the terminal needs to access, so as to switch the terminal from the current cell corresponding to the current beam to the target cell corresponding to the target beam. According to the above content, the present application realizes threshold value judgment for the beam signal strength corresponding to each initial beam through the beam signal strength corresponding to each initial beam and the signal strength threshold value corresponding to each initial beam, and then uses the initial beam whose beam signal strength is greater than the signal strength threshold value as a candidate beam; thereby ensuring that the candidate beams can meet the beam signal strength requirements of the terminal, and ensuring that after the target beam is subsequently determined from the candidate beams, the target beam can effectively ensure the stability of the terminal's access beam signal to prevent the terminal's communication quality from being affected, and 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.
