[0068] In order to make the purposes, technical solutions and advantages of the present application clearer, further detailed description will be made to the present application in combination 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.

[0069] The method of network frequency reuse provided by the embodiments of the present application can be applied in the application environment as shown in FIG. 1, wherein the satellite / cellular coordination scheduler 101 is connected with the ground base station 102 in the cellular network and the ground gateway station 103 in the satellite network respectively, that is, the satellite network and the cellular network are connected through the satellite / cellular coordination scheduler 101. The ground gateway station 103 can establish a connection with the satellite base station 104 and transmit data, and the ground gateway station 103 can establish a connection with the 5G core network (5G Core network, 5GC) 105 through the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) NG interface and transmit data.

[0070] In the related art, since the coverage area of the satellite network and the coverage area of the cellular network will appear a coverage overlap area, it is possible to cause the problem of co-channel interference of the satellite network and the cellular network, so that the signal quality of the satellite network and the cellular network is reduced, thereby affecting the data transmission rate and reliability, and affecting the experience of the users in the coverage overlap area of the satellite network and the cellular network.

[0071] Based on this, in order to solve the problem of co-frequency interference between satellite network and cellular network, the embodiments of the present application provide four scenarios as shown in FIG. 1, including a first scenario, a second scenario, a third scenario and a fourth scenario. The first scenario is that the satellite network and the cellular network have no overlapping coverage area, such as remote rural areas, deserts, forests or ocean areas, etc. The second scenario is that the satellite network and the cellular network have completely overlapping coverage areas, such as densely populated cities, county towns and general rural areas. The third scenario is that the satellite network and the cellular network have partially overlapping coverage areas, such as rural areas with sporadic residents, grasslands, mountainous areas or high-rise blocking areas in cities. The fourth scenario is that the satellite network and the cellular network have no overlapping coverage areas, and the satellite base station leaves the coverage area of the cellular network. Among them, the Geostationary Orbit (GEO) will involve the first scenario to the third scenario, and the Low Earth Orbit (LEO) will involve the first scenario to the fourth scenario. The dashed line shown in FIG. 1 is the coverage area of the satellite base station 104.

[0072] In an exemplary embodiment, in order to solve the above technical problems, as shown in FIG. 2, a network frequency multiplexing method is provided, which is taken as an example to illustrate the application of the method to the satellite / cellular coordination scheduler in FIG. 1, wherein:

[0073] Step 201, determining a target scenario according to signal strength data of a first network and signal strength data of a second network.

[0074] The first network can be a satellite network, which can refer to a non-ground network or a non-terrestrial network (NTN). The NTN can refer to a wireless communication network constructed by satellites, high-altitude airships or other celestial objects, and does not rely on ground facilities. The NTN provides wide-area coverage and can cover areas that cannot be covered by a ground network, such as oceans, polar regions, deserts, mountains, forests and other remote areas, to achieve global communication coverage. The second network can be a cellular network, which can refer to a ground network (TN). The TN can refer to a traditional wireless cellular network constructed by ground base stations and corresponding wireless communication devices. The TN provides local coverage and constructs a communication coverage network through ground base stations to provide wireless communication services within a local range. The signal strength data of the first network can be reported satellite downlink reference signal RSSI (Received Signal Strength Indication) data. The signal strength data of the second network can be cellular downlink reference signal RSRP (Reference Signal Received Power) data. The target scenario can be a scenario in which the target terminal is located. The target scenario can be divided according to the tracking area of the first network and the tracking area of the second network.

[0075] In one example, the satellite / cellular coordination scheduler receives the signal strength data of the first network and the signal strength data of the second network sent by the target terminal, analyzes the first network and the second network based on the signal strength data of the first network and the signal strength data of the second network, obtains the relevant situation of the first network and the second network, and determines the target scenario in which the target terminal is located according to the relevant situation of the first network and the second network. For example, the satellite / cellular coordination scheduler can determine the target scenario in which the target terminal is located according to the tracking area of the first network and the tracking area of the second network at the location of the target terminal.

[0076] Step 202, determining a target resource scheduling strategy corresponding to the target scenario based on a preset correspondence between the scenario and the resource scheduling strategy.

[0077] The preset scenario can be a scenario in which the terminal can appear. The resource scheduling strategy can be a method of scheduling resources of a network shared frequency occupied by the first network and the second network according to the preset scenario. The resource scheduling can be achieved by dynamically dividing the network shared frequency in time, frequency or wavelength.

[0078] Specifically, the satellite / cellular coordination scheduler sets a corresponding resource scheduling strategy for a possible scenario of a terminal, and different scenarios can correspond to different resource scheduling strategies. A database can be set in the satellite / cellular coordination scheduler, and the corresponding relationship between the preset scenarios and the resource scheduling strategies is added to the database. Specifically, the satellite / cellular coordination scheduler corresponds to a target scenario of a target terminal identified, and obtains a target resource scheduling strategy corresponding to the target scenario from the database.

[0079] In step 203, the resource blocks of the network sharing frequency are allocated based on the target resource scheduling strategy, and the first resource blocks corresponding to the first network and the second resource blocks corresponding to the second network are determined.

[0080] The network sharing frequency is the shared frequency of the first network and the second network. The resource block (RB) is divided from the time domain and the frequency domain.

[0081] Specifically, the satellite / cellular coordination scheduler allocates the resource blocks of the network sharing frequency based on the target resource scheduling strategy corresponding to the target scenario. The first network and the second network can occupy the resource blocks of the network sharing frequency according to the allocation result of the resource blocks of the network sharing frequency, so as to obtain the first resource blocks corresponding to the first network and the second resource blocks corresponding to the second network according to the occupation, and reasonably multiplex the network sharing frequency of the first network and the second network to avoid co-frequency interference. Illustratively, based on the target resource scheduling strategy, the first network and the second network occupy the resource blocks of the network sharing frequency, which can allocate all the resource blocks of the network sharing frequency to the first resource blocks of the first network or the second resource blocks of the second network, or reasonably allocate the network sharing resource to the first network and the second network according to the actual target scenario, which is not limited herein. The embodiments of the present application can improve the frequency multiplexing rate and the spectrum efficiency of the first network and the second network according to different coordination scheduling strategies according to different scenarios of the target terminal.

[0082] In the above method of network frequency multiplexing, the target scenario is determined according to the signal strength information of the first network and the signal strength data of the second network, and the resource blocks of the network sharing frequency are allocated to the first resource blocks of the first network and the second resource blocks of the second network according to the target scenario and the target resource scheduling strategy corresponding to the target scenario, so as to improve the signal quality of the first network and the second network, thereby improving the user experience of the first network and the second network.

[0083] In one exemplary embodiment, the target scenario is determined according to the signal strength data of the first network and the signal strength data of the second network, comprising:

[0084] determine a first tracking area of the first network based on the signal strength data of the first network, determine a second tracking area of the second network based on the signal strength data of the second network, calculate an overlap coverage of the first network and the second network based on the first tracking area and the second tracking area, and determine the target scenario based on the overlap coverage.

[0085] The tracking area (TA) can represent the location information of the target terminal. The overlap coverage can represent the overlap of the first network and the second network at the location of the target terminal. The target terminal can be one terminal or multiple terminals, which is not limited herein. The overlap can refer to the coverage of the corresponding second network under the coverage of the first network.

[0086] Specifically, the satellite / cellular coordination scheduler can determine the first tracking area of the first network based on the received signal strength data of the first network, determine the second tracking area of the second network based on the received signal strength data of the second network, match the first tracking area and the second tracking area to determine the geographical location of the target terminal, and determine the overlap coverage of the first network and the second network. The satellite / cellular coordination scheduler determines the target scenario of the target terminal based on the overlap coverage. The embodiments of the present application determine the target scenario by calculating the overlap coverage of the first network and the second network at the location of the target terminal, so as to facilitate subsequent determination of the target resource scheduling strategy for allocating shared network resources.

[0087] In one exemplary embodiment, the target scenario is one of the following scenarios: a first scenario, a second scenario, a third scenario, and a fourth scenario. Determining the target scenario based on the overlap coverage includes:

[0088] If the overlap coverage meets a first threshold and the second tracking area is not detected in the case of detecting the first tracking area, the target scenario is determined as the first scenario. If the overlap coverage meets a second threshold, the target scenario is determined as the second scenario. If the overlap coverage meets a value greater than the first threshold and less than the second threshold, the target scenario is determined as the third scenario. If the overlap coverage meets the first threshold and the first tracking area is not detected in the case of detecting the second tracking area, the target scenario is determined as the fourth scenario.

[0089] The overlap coverage meeting the first threshold means that the overlap coverage is equal to the first threshold. Similarly, the overlap coverage meeting the second threshold means that the overlap coverage is equal to the second threshold.

[0090] The first threshold value is less than the second threshold value, the first threshold value can be 0, and the first threshold value represents a case where the coverage range of the first network and the coverage range of the second network have no overlapping coverage. The second threshold value can be 1, and the second threshold value represents a case where the coverage range of the first network and the coverage range of the second network completely overlap. The case where the overlapping coverage rate is greater than the first threshold value and less than the second threshold value represents a case where the coverage range of the first network and the coverage range of the second network partially overlap.

[0091] Specifically, if the overlapping coverage rate meets the first threshold value and the second tracking area is not detected in the case where the first tracking area is detected, it represents that the first network and the second network have no overlapping coverage area, the location where the target terminal is located only detects the coverage of the first network and does not detect the coverage of the second network, and the satellite / cellular coordination scheduler can determine the location where the target terminal is located as the first scenario. Exemplarily, the first scenario can be remote rural, desert, forest or ocean areas. If the overlapping coverage rate meets the second threshold value, it represents that the first network and the second network have complete coverage area, the location where the target terminal is located detects both the coverage of the first network and the coverage of the second network, and the satellite / cellular coordination scheduler can determine the location where the target terminal is located as the second scenario. Exemplarily, the second scenario can be densely populated urban, county and general rural areas. If the overlapping coverage rate meets a value greater than the first threshold value and less than the second threshold value, it represents that the coverage range of the first network and the coverage range of the second network partially overlap, and the location where the target terminal is located detects both the coverage of the first network and the coverage of the second network. The satellite / cellular coordination scheduler can determine the location where the target terminal is located as the third scenario. Exemplarily, the third scenario can be a rural area with sporadic residents, a grassland, a mountainous area or a high-rise blocking area in a city. If the overlapping coverage rate meets the first threshold value and the first tracking area is not detected in the case where the second tracking area is detected, it represents that the first network and the second network have no overlapping coverage area, and the location where the target terminal is located only detects the coverage of the second network and does not detect the coverage of the first network. The satellite / cellular coordination scheduler can determine the location where the target terminal is located as the fourth scenario. It should be understood that the above examples of specific scenarios are only examples and cannot constitute specific limitations.

[0092] In an exemplary embodiment, the network shared frequency resource blocks are allocated based on the target resource scheduling strategy, and the first resource block of the first network and the second resource block of the second network are determined, comprising:

[0093] If the target scenario is the first scenario, all resource blocks corresponding to the network shared frequency are determined as the first resource block used by the first network.

[0094] Specifically, the satellite / cellular coordination scheduler determines that the target scenario in which the target terminal is located is the first scenario, and then makes the first network fully occupy the resource blocks of the network-shared frequency. The first network uses the first resource blocks, and the first network fails to occupy the resource blocks of the network-shared frequency. The embodiment of the present application fully occupies the resource blocks of the network-shared frequency by the first network in the first scenario, and improves the resource utilization of the first scenario and the utilization efficiency of the spectrum.

[0095] In an exemplary embodiment, the resource blocks of the network-shared frequency are allocated based on a target resource scheduling strategy, and the first resource blocks of the first network and the second resource blocks of the second network are determined, including:

[0096] If the target scenario is the second scenario, the traffic statistics of the second network are obtained, the target resource blocks are determined in the resource blocks of the network-shared frequency according to the traffic statistics, and the target resource blocks are used as the second resource blocks used by the second network. The first resource blocks used by the first network are determined according to the resource blocks of the network-shared frequency, the second resource blocks, and a preset allocation mode.

[0097] The traffic statistics can be the traffic required by the target terminal, and the preset allocation mode can be a static sharing mode or a dynamic sharing mode.

[0098] Specifically, the satellite / cellular coordination scheduler makes the first network preferentially occupy the resource blocks of the network-shared frequency that meet the demand of the traffic statistics of the second network according to the traffic statistics of the second network in the target scenario, and the remaining resource blocks are occupied by the first network through static sharing (pre-set RB according to traffic statistics) or dynamic sharing (instantaneous time division or frequency division). The embodiment of the present application ensures that the second network provides high-capacity and low-delay communication services, and the first network can provide backup and redundancy, effectively avoiding frequency interference through static division or dynamic time division or frequency division. As shown in FIG. 3 and FIG. 4, FIG. 3 is a schematic diagram of instantaneous time division of the first network and the second network in an embodiment. The resource blocks of the network-shared frequency are divided according to time to obtain equal division of a plurality of time slices. The second network can preferentially occupy the resource blocks of the network-shared frequency according to the traffic statistics (the gray cells in FIG. 3 are the resource blocks occupied by the second network), and the first network can occupy the remaining resource blocks (the blank cells in FIG. 3 are the resource blocks occupied by the first network). FIG. 4 is a schematic diagram of instantaneous frequency division of the first network and the second network in an embodiment. The gray cells in FIG. 4 are the resource blocks occupied by the second network, and the blank cells in FIG. 4 are the resource blocks occupied by the first network.

[0099] In an example embodiment, the resource blocks of the network sharing frequency are allocated based on a target resource scheduling strategy, and the first resource blocks of the first network and the second resource blocks of the second network are determined, including:

[0100] If the target scenario is the third scenario, the beam type of the first network is obtained; the beam spot area of the first network is determined based on the beam type; and the entire resource blocks corresponding to the network sharing frequency are determined as the first resource blocks of the first network or the second resource blocks of the second network according to the beam spot area and the position information of the target terminal.

[0101] The beam type can include a wide beam and a narrow beam, and the specific beam type can be set according to the actual scenario. The coverage range of the first network can be composed of beams, and the beam spot area can be the overlapping coverage area of the first network and the second network.

[0102] Specifically, in the third scenario, the satellite / cellular coordination scheduler can set the beam type of the first network according to the position information of the target terminal. If the beam type is a wide beam, the beam spot area of the first network is determined according to the overlapping coverage area of the first network and the second network. When the satellite / cellular coordination scheduler determines that the target terminal is in the overlapping coverage area of the first network and the second network, the entire resource blocks corresponding to the network sharing frequency are determined as the first resource blocks of the first network. When the satellite / cellular coordination scheduler determines that the target terminal is not in the overlapping coverage area of the first network and the second network (in the coverage area of the first network and not in the coverage area of the second network), the entire resource blocks corresponding to the network sharing frequency are determined as the second resource blocks of the second network. For example, as shown in FIG. 5, FIG. 5 is a schematic diagram of a wide beam of the first network in an example embodiment. FIG. 5 includes a base station of the first network and a base station of the second network. The two solid lines represent the wide beam area of the first network, and the two dashed lines represent the wide beam spot area of the first network. If the beam type is a narrow beam, the beam spot area of the first network is determined according to the overlapping coverage area of the first network and the second network. When the satellite / cellular coordination scheduler determines that the target terminal is in the coverage area of the first network, the entire resource blocks corresponding to the network sharing frequency are determined as the first resource blocks of the first network. When the satellite / cellular coordination scheduler determines that the target terminal is in the coverage area of the second network, the entire resource blocks corresponding to the network sharing frequency are determined as the second resource blocks of the second network. For example, as shown in FIG. 6, FIG. 6 is a schematic diagram of a narrow beam of the first network in an example embodiment. FIG. 6 includes a base station of the first network and a base station of the second network. The two solid lines represent the narrow beam area of the first network, and the two dashed lines represent the wide beam spot area of the first network. The narrow beam can be applied to a scenario with few users, and the beam can be dynamically adjusted.

[0103] In an example embodiment, the target resource scheduling strategy is used to allocate resource blocks of the network sharing frequency, and the first resource blocks of the first network and the second resource blocks of the second network are determined, including:

[0104] If the target scenario is the fourth scenario, the resource blocks of the network sharing frequency are all determined as the second resource blocks used by the second network.

[0105] Specifically, when the satellite / cellular coordination scheduler determines that the target scenario of the target terminal is the fourth scenario, the second network completely occupies the resource blocks of the network sharing frequency, and the second resource blocks used by the second network are determined, and the first network fails to occupy the resource blocks of the network sharing frequency. The embodiments of the present application completely occupy the resource blocks of the network sharing frequency by the second network in the fourth scenario, which improves the resource utilization of the fourth scenario and improves the utilization efficiency of the frequency spectrum.

[0106] In an example embodiment, the method for network frequency multiplexing further includes:

[0107] The first task index of the first network and the second task index of the second network are obtained, and the target resource scheduling strategy is adjusted based on the first task index and the second task index.

[0108] The task index can represent the signal condition of the target terminal after the current network executes the target resource scheduling strategy, and the task index can include but is not limited to: uplink and downlink transmission rate, time delay information, data packet loss condition, network switching success rate, and satellite / cellular coordination scheduler recorded success rate (connection), etc.

[0109] Specifically, the satellite / cellular coordination scheduler can obtain the first task indicator of the first network and the second task indicator of the second network in real time, and determine the signal condition received by the target terminal after the first network and the second network execute the target resource scheduling strategy according to the first task indicator and the second task indicator. The satellite / cellular coordination scheduler judges whether the signal condition received by the target terminal is lower than the set threshold, and in the case that the signal condition received by the target terminal is lower than the set threshold, the target resource scheduling strategy is dynamically adjusted according to the first task indicator and the second task indicator. Exemplarily, the satellite / cellular coordination scheduler can adjust the frequency division or time division proportion of the dynamic network sharing frequency, the beam "spot" size, etc. according to the task indicator. The embodiments of the present application continuously dynamically optimize the resource scheduling strategy by detecting the task indicator and adjusting the target resource scheduling strategy according to the task indicator, thereby improving the system performance and scheduling accuracy of the first network and the second network. Specifically, the satellite / cellular coordination scheduler continuously dynamically adjusts the satellite / cellular coordination scheduling strategy, thereby improving the spectrum utilization and spectrum efficiency of the first network and the second network, improving the performance and user perception of the first network and the second network, and reducing the cost of network construction and optimization of the first network and the second network.
