[0048] 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.

[0049] Currently, 5G+ networks are all deployed in cellular mode. In scenarios where ground networks and low-altitude networks coexist, there will be a problem of co-frequency interference between ground services and low-altitude services. Figure 1 As shown in the figure, in addition to the service cell, the surrounding neighboring cells will cause co-frequency downlink interference to low-flying drones, and drones will also cause co-frequency interference to the uplink of ground base stations, resulting in a decrease in the signal quality of low-altitude networks and ground networks, thereby affecting data transmission rate and reliability, and seriously affecting the user experience of low-altitude networks and ground networks. However, 6G cellular has not yet been deployed on a large scale, and it is difficult to carry out large-scale transformation of the existing network. Therefore, it is necessary to find an effective solution in the current 5G+ network to solve the above interference problem.

[0050] refer to Figure 2, which is a schematic diagram of the solution provided by the present application for the above-mentioned interference problem. The present application proposes a method for dynamically combining cellular and non-cellular networks to improve the coexistence of low-altitude and ground networks, by adding a control unit for dynamically combining cellular and non-cellular networks in a system where ground terminals (such as mobile phones, tablets, computers, etc.) and low-altitude terminals (such as drones, low-altitude aircraft, etc.) coexist, and the control unit is connected to all cellular base stations along the flight line of the low-altitude terminal. Thus, the ground network and the low-altitude network can be effectively connected through the control unit, and the network structure can be adjusted in real time according to the network performance index values ​​of the neighboring cellular base stations reported by the low-altitude terminals, and different combinations of cellular base stations (including only cellular units (Cell Based Unit, CBU)) and hybrid base stations (including cellular units + non-cellular units (Cell Free Unit, CFU)) are dynamically formed. The cellular unit (CBU) of the hybrid base station serves ground users, and the non-cellular unit (CFU) serves low-altitude terminals. Each CBU (jm) and CFU (m) dynamically shares wireless resources in time, frequency or space, greatly improving resource reuse rate and spectrum efficiency, and greatly reducing mutual (co-frequency) interference between ground networks (with cellular networks) and low-altitude networks (without cellular networks). At the same time, multiple CFU (1), CFU (2), ... CFU (m) are merged into a large non-cellular network, dynamically realizing various multiplexing combinations when serving low-altitude terminals. Low-altitude terminals do not need to switch between different non-cellular units, reducing latency, effectively solving the co-frequency interference problem when low-altitude and ground networks coexist, and significantly improving the overall system performance, saving the cost of network construction and optimization.

[0051] In one embodiment, Figure 3 As shown, it is a flow chart of the communication control method provided by the present application. Figure 2 Taking the control unit in as an example, the method comprises the following steps:

[0052] Step S310: receiving network performance indicator values ​​of neighboring cellular base stations located around the low-altitude terminal and sent by the low-altitude terminal.

[0053] The network performance index value is a measured value of an index for evaluating the quality of network signals. For example, the network performance index value may be a reference signal received power (RSRP), a signal to interference plus noise ratio (SINR), and the like.

[0054] In the specific implementation, the low-altitude terminal measures the network performance index values ​​of multiple cellular base stations around its location while flying along the flight line, and reports them to the control unit through the service cell. After receiving these network performance index values, the control unit can further dynamically adjust the structure of the coexistence network according to the network performance index values.

[0055] Step S320: Determine a target cellular base station that meets the requirements from neighboring cellular base stations according to the network performance indicator value.

[0056] In specific implementation, the larger the network performance index value is, the better the signal quality is, the closer the low-altitude terminal is to the cellular base station or the better the communication effect is. Therefore, according to the network performance index value, the specific method for determining the target cellular base station that meets the requirements from the neighboring cellular base stations can be: determining the cellular base station with a network performance index value greater than the threshold from the neighboring cellular base stations as the target cellular base station.

[0057] Step S330, adjust the type of the target cellular base station to a hybrid base station; a hybrid base station refers to a base station that includes cellular units and non-cellular units, wherein the cellular units serve ground terminals and the non-cellular units serve low-altitude terminals, and the cellular units and non-cellular units in the hybrid base station dynamically share wireless resources.

[0058] Among them, the Cell Free Unit (CFU) realizes direct connection between users and the network in the communication network. CFU adopts a distributed architecture. CFU can transmit data through multiple distributed antenna systems, significantly improving network coverage and signal quality. CFU does not require users to frequently switch between different units, and can connect seamlessly, reducing latency and improving the continuity of data transmission, thereby providing a more stable and efficient user experience.

[0059] Among them, the Cell Based Unit (CBU) is a traditional cellular communication system that serves users through specific base stations and multiple cells. The CBU is responsible for managing the connection and communication of user devices within its coverage area. It transmits signals through the cellular network and uses infrastructure such as towers and base stations to maintain the stable operation of the network.

[0060] In a specific implementation, a cellular base station is composed of cellular units. Adjusting the type of a target cellular base station to a hybrid base station including both cellular units and non-cellular units can be obtained by changing some of the cellular units in the cellular base station into non-cellular units, that is, dynamically splitting the traditional cellular base station into cellular and non-cellular units, thereby realizing the conversion of the base station type.

[0061] It is understandable that as the low-altitude terminal changes its flight position during flight, all cellular base stations along its flight path will dynamically change between cellular base stations and hybrid base stations. However, the cellular units in the hybrid base station continue to serve ground terminals (such as mobile phones, tablets, computers, etc.), while the non-cellular units will serve the low-altitude terminal.

[0062] In addition, wireless resources are dynamically shared between the cellular units and non-cellular units in each dynamically formed hybrid base station to reduce mutual (co-frequency) interference between the ground network (cellular network) and the low-altitude network (non-cellular network).

[0063] In addition, the hybrid base station (HBS) includes both a cellular unit (CBU) and a cellular-free unit (CFU), combining traditional cellular networks with emerging cellular-free technologies. The CBU is responsible for managing traditional cellular channels, while the CFU integrates multiple access points to achieve collaborative signal processing. This combination enables both ordinary users and high-traffic users to obtain reasonable service quality and network resource allocation. Through a more flexible network structure and the linkage between CBU and CFU, interference and signal attenuation can be effectively reduced, improving the user's communication experience.

[0064] In the above communication control method, by adding a control unit architecture that can dynamically combine cellular units and non-cellular units in the system where the ground terminal and the low-altitude terminal coexist, the ground network and the low-altitude network can be effectively connected, so that the traditional cellular base station can be dynamically split into cellular units and non-cellular units in the future, and serve the ground terminal and the low-altitude terminal at the same time, and by dynamically sharing wireless resources between cellular units and non-cellular units, the mutual (co-frequency) interference between the ground network (cellular network) and the low-altitude network (non-cellular network) when coexisting is reduced, the network performance of the low-altitude network and the ground network is improved, the dual user perception of ground users and low-altitude users is improved, the wireless resource reuse rate and spectrum efficiency of the low-altitude network and the ground network are improved, and higher communication capacity and bandwidth utilization are achieved. Reduce the cost of construction and optimization of low-altitude networks and ground networks, it has considerable economic value and broad application prospects. At the same time, according to the network performance index values ​​of multiple cellular base stations around it measured and reported by the low-altitude terminal, the target cellular base station that needs to be converted is determined, which can ensure the signal quality of the hybrid base station converted from the target cellular base station.

[0065] In an exemplary embodiment, the above step S320, based on the network performance indicator value, determines a target cellular base station that meets the requirements from the neighboring cellular base stations, including: determining a cellular base station whose network performance indicator value is greater than a threshold from the neighboring cellular base stations as the target cellular base station.

[0066] In a specific implementation, the control unit may compare the network performance index value of the cellular base station reported by the low-altitude terminal with the threshold, and take the cellular base station with a network performance index value greater than the threshold as the target cellular base station.

[0067] More specifically, the network performance indicator value may include a reference signal received power (RSRP) and a signal to interference plus noise ratio (SINR), and RSRP and SINR have corresponding thresholds, respectively, which are recorded as a first threshold and a second threshold. The control unit may compare the measured value of the cellular downlink reference signal received power (RSRP) with the first threshold, and compare the measured value of the signal to interference plus noise ratio (SINR) with the second threshold. If the measured value of the RSRP of a certain cellular base station is greater than the first threshold, and the measured value of the SINR is greater than the second threshold, such a cellular base station is taken as a target cellular base station.

[0068] In this embodiment, by taking the cellular base station with a network performance index value greater than a threshold around the low-altitude terminal as the target cellular base station, it can be ensured that the hybrid base station obtained by subsequent conversion has good signal quality.

[0069] In an exemplary embodiment, the method also includes: determining the location and resource occupancy of ground terminals served by cellular units in the hybrid base station, as well as the location and service demand of low-altitude terminals served by non-cellular units; and performing at least one of time division sharing, frequency division sharing and space division sharing between cellular units and non-cellular units in the hybrid base station based on the location and resource occupancy of the ground terminals, as well as the location and service demand of the low-altitude terminals.

[0070] Among them, the resource occupancy of the ground terminal includes the wireless resource occupancy and the beam resource occupancy.

[0071] In a specific implementation, the dynamic sharing of wireless resources between the cellular unit and the non-cellular unit in the hybrid base station may include at least one of time-division sharing, frequency-division sharing, and space-division sharing, that is, any one of the sharing, or a combination of any two or three types of sharing. To dynamically share unlimited resources, the location and resource occupancy of the ground terminal served by the cellular unit in the hybrid base station, as well as the location and service demand of the low-altitude terminal served by the non-cellular unit, may be determined first. Based on the location and resource occupancy of the ground terminal, as well as the location and service demand of the low-altitude terminal, at least one of time-division sharing, frequency-division sharing, and space-division sharing may be performed between the cellular unit and the non-cellular unit.

[0072] In this embodiment, by dynamically implementing time division sharing, frequency division sharing, space division sharing, and a combination of two or three of them between the cellular units and the non-cellular units in each hybrid base station, the mutual (same-frequency) interference between the ground network (cellular network) and the low-altitude network (non-cellular network) can be greatly reduced.

[0073] In an exemplary embodiment, the method also includes: adjusting in real time, according to the flight position of the low-altitude terminal, the type of cellular base stations whose network performance indicator values ​​along the flight line of the low-altitude terminal meet the requirements, to obtain multiple hybrid base stations; merging the non-cellular units in each hybrid base station to obtain a non-cellular network; and controlling the dynamic multiplexing of wireless resources between each non-cellular unit in the non-cellular network.

[0074] Specifically, as the low-altitude terminal changes its flight position during flight, new hybrid base stations will be continuously formed, thereby obtaining multiple hybrid base stations. In this case, the non-cellular units in each hybrid base station can also be merged (combined) into a large non-cellular network to dynamically form a (large) single cell, that is, the non-cellular units of each hybrid base station become a CFU (i) in the non-cellular network. Then, the wireless resources can be dynamically reused between the non-cellular units in the non-cellular network.

[0075] Furthermore, in an exemplary embodiment, the above-mentioned step of controlling the dynamic multiplexing of wireless resources between the various non-cellular units in the non-cellular network includes: determining the location and service demand of the low-altitude terminals served by each non-cellular unit; and dynamically multiplexing the wireless resources by at least one of time division multiplexing, frequency division multiplexing and space division multiplexing according to the location and service demand of the low-altitude terminals.

[0076] Among them, time division multiplexing (TDM) is a multiplexing technology that divides time into multiple time slots to provide multiple signals with the opportunity to be transmitted alternately in the same channel. Each signal occupies the channel in its assigned time slot and is transmitted in turn. TDM can efficiently transmit multiple signals on a single channel, which helps to improve channel utilization and reduce the number of physical lines, making the communication system more cost-effective. Since time division multiplexing can only transmit a single signal per time slot, it is suitable for periodic transmission needs.

[0077] Frequency Division Multiplexing (FDM) is a technology that distributes signals to different frequency bandwidths, thereby transmitting multiple signals simultaneously in the same channel. Each signal operates in an independent frequency band to avoid mutual interference. FDM allows different signals to be transmitted in parallel, thereby greatly increasing the efficiency of bandwidth utilization.

[0078] Space Division Multiplexing (SDM) is a technology that implements signal transmission in physical space, allowing multiple signals to be transmitted simultaneously on the same frequency through different spatial paths. It is usually implemented through a multi-antenna array. SDM technology can significantly improve the capacity and transmission efficiency of the network. By connecting multiple antenna arrays in parallel, existing resources can be effectively utilized, significantly increasing bandwidth and capacity. When using SDM, multiple signals or data streams can be transmitted simultaneously on the same frequency without interference.

[0079] Specifically, when the wireless resources are dynamically multiplexed between the non-cellular units in the non-cellular network for control, the location of the low-altitude terminal served by each non-cellular unit in the non-cellular network and the service demand of the low-altitude terminal can be determined first. According to the location and service demand of the low-altitude terminal, the wireless resources are dynamically multiplexed in at least one of time division multiplexing, frequency division multiplexing and space division multiplexing, that is, any one of the multiplexing can be performed alone, or a combination of any two types of multiplexing or a combination of the three types of multiplexing can be performed.

[0080] In this embodiment, the non-cellular units in each hybrid base station are merged into a large non-cellular network, and various multiplexing combinations are dynamically implemented when serving low-altitude terminals, thereby eliminating the need for switching between different non-cellular units. Seamless connection can be achieved, latency can be reduced, and the continuity and reliability of data transmission can be improved, providing a more stable and efficient user experience.

[0081] In an exemplary embodiment, when the low-altitude terminal communicates with multiple hybrid base stations, the uplink and downlink of the communication come from the same hybrid base station, or from different hybrid base stations. In other words, the solution of the present application is suitable for both uplink and downlink coming from the same hybrid base station and uplink and downlink coming from different hybrid base stations, and has a wider scope of application.

[0082] In one embodiment, in order to facilitate those skilled in the art to understand the embodiments of the present application, the following will be described with reference to specific examples of the accompanying drawings. Figure 4 , shows a specific flow chart of a communication control method, including the following process:

[0083] Step S410: The control unit receives RSRP and SINR of multiple cellular base stations around the low-altitude terminal reported by the low-altitude terminal.

[0084] In step S420, the control unit compares RSRP with a first threshold, compares SINR with a second threshold, and converts a cellular base station whose RSRP is greater than the first threshold and whose SINR is greater than the second threshold into a hybrid base station.

[0085] Among them, the hybrid base station has cellular units to serve ground terminals, and has no cellular units to serve low-altitude terminals.

[0086] Step S430: Dynamic sharing of wireless resources in terms of time division, frequency division, and space division (or a combination thereof) is dynamically implemented between the cellular units and the non-cellular units of each dynamically formed hybrid base station.

[0087] In step S440, the non-cellular units of multiple hybrid base stations are dynamically merged into a large non-cellular network, and the wireless resources of the multiple non-cellular units are dynamically multiplexed by time division, frequency division, and space division (or a combination thereof).

[0088] In step S450, the control unit continuously obtains KPI indicator feedback of real-time monitoring of cellular and non-cellular networks, optimizes and adjusts the dynamic sharing strategy of wireless resources between cellular and non-cellular networks and the dynamic multiplexing strategy of multiple CFU wireless resources, so as to improve the overall system performance and user perception of cellular and non-cellular networks.

[0089] Step S460, step S410-step S450 are continuously cycled, so that the control unit is continuously and dynamically combined to form a series of different hybrid base stations, and the dynamic sharing strategy of wireless resources between cellular units and non-cellular units is continuously and dynamically adjusted, as well as the dynamic multiplexing strategy of wireless resources between multiple non-cellular units, so as to improve the wireless resource multiplexing rate and spectrum efficiency of the ground network (cellular network) and the low-altitude network (non-cellular network), improve the performance and user perception of the ground network and the low-altitude network, and reduce the cost of construction and optimization of the ground network and the low-altitude network.

[0090] refer to Figure 5 , which is a schematic diagram of resource sharing and resource multiplexing shown in an embodiment. The left part of the figure shows frequency division sharing of wireless resources between a cellular unit (CBU) and a cellular-free unit (CFU), and the right part shows frequency division multiplexing of wireless resources between multiple cellular-free units (CFU). Among them, RB stands for resource block (Resource Block), which is 12 subcarriers in the frequency domain. RB is further divided into PRB (physical resource block) and VRB (virtual resource block). RBG stands for resource block group (Resource Block Group). In 5G NR, RBG is the basic unit of frequency domain resource allocation. RBG is a set of multiple adjacent virtual resource blocks (VRBs), and its size depends on the settings of the bandwidth part (BWP) and configuration parameters (such as RBG-SIZE).

[0091] refer to Figure 6, is a schematic diagram of resource sharing and resource reuse according to another embodiment. The left part of the figure shows time-division sharing of wireless resources between a cellular unit (CBU) and a cellular-free unit (CFU), and the right part shows time-division reuse of wireless resources between multiple cellular-free units (CFU).

[0092] refer to Figure 7 , is a schematic diagram of resource sharing and resource reuse shown in another embodiment. The left part of the figure shows that a cellular unit (CBU) and a cellular-free unit (CFU) perform space division + time division sharing of wireless resources, and the right part shows that multiple cellular-free units (CFU) perform space division + time division reuse of wireless resources.

[0093] The communication control method provided by this application has the following beneficial effects:

[0094] (1) In the scenario where 5G+ / 6G low-altitude networks and ground networks coexist, an innovative method of combining traditional cellular networks with emerging non-cellular networks is proposed. The network structure is adjusted in real time through a newly added dynamic combination control unit of cellular and non-cellular networks to achieve a dynamic cellular and non-cellular hybrid architecture, making the management and allocation of network resources more flexible and adapting to the different needs of ground users and low-altitude users.

[0095] (2) Allow low-altitude terminals to monitor the signal quality of neighboring cellular base stations and make intelligent judgments based on the reported RSRP and SINR values. Dynamically adjust the network architecture and wireless resources based on user location and needs to ensure dynamic selection of the best connection for low-altitude terminals, providing a more stable and efficient user experience.

[0096] (3) It can monitor and dynamically adjust wireless resources in real time to ensure that the communication needs of ground terminals and low-altitude terminals are effectively met, improve the utilization of wireless resources, and improve the overall network efficiency.

[0097] (4) Dynamic sharing of wireless resources within the hybrid base station can be achieved. Sharing strategies such as time division, frequency division, space division and their combination can be adopted to allocate resources according to the needs of different terminals, significantly reducing the co-channel interference between the low-altitude network and the ground network, improving signal quality and network performance, and improving the wireless resource reuse rate and spectrum efficiency of the ground network (with cellular network) and the low-altitude network (without cellular network).

[0098] (5) The non-cellular units of multiple hybrid base stations can be dynamically merged to form a large non-cellular network. The wireless resources of the non-cellular network adopt different dynamic multiplexing strategies to achieve seamless connection.
