[0001] Cross-reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202411076560.5, filed on August 6, 2024, and entitled "Satellite interference information determination method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to a satellite interference information determination method and a communication apparatus. BACKGROUND

[0004] With the development of communication technology, satellites are increasingly widely used. For example, in the application scenario of satellite detection, a satellite transmits a microwave signal to the ground and receives a microwave signal reflected in the beam range, and then processes the received microwave signal to obtain an image.

[0005] A large number of ground access network devices (such as ground base stations) are deployed on the ground. When the ground access network devices use satellite frequency bands, the signals transmitted by the ground access network devices can interfere with the receiver of the satellite and affect the quality of service of the satellite. Therefore, in order to protect the quality of service of the satellite, the total interference information of the ground access network devices to the satellite can be collected, and the interference of the ground access network devices to the satellite is managed based on the total interference information. However, how to collect the total interference information of the ground access network devices to the satellite is a technical problem to be solved at present. SUMMARY

[0006] The embodiments of the present application provide a satellite interference information determination method and a communication apparatus, which are used to collect the total interference information of the ground access network devices to the satellite.

[0007] In a first aspect, a satellite interference information determination method is provided. The method can be performed by a first apparatus. The first apparatus can be a management service producer or a component in the management service producer. The management service producer can be deployed in a cross-domain management function unit or a domain management function unit. The management service producer can be a network device such as a network function (NF) or a server, and the embodiments of the present application do not limit this. Taking the first apparatus as a management service producer as an example, the method comprises: receiving first information from a second apparatus, the first information comprising interference information of the second apparatus to a first satellite in a first direction at a first time, the first direction being used to indicate a direction of the first satellite relative to the second apparatus; and determining total interference information of the first satellite based on the first information.

[0008] In the embodiments of the present application, the first device can receive the interference information from the second device, collect the interference information of the second device to the first satellite, and determine the total interference information of the first satellite based on the interference information, so as to collect the total interference information of the satellite from the plurality of second devices. For example, the first device can receive the interference information from the plurality of second devices, and determine the total interference information of the plurality of second devices to the first satellite based on the interference information from the plurality of second devices. In addition, when the first device determines the total interference information of the first satellite, the interference information used is the interference information of the second device in the first direction, and does not include the interference information of the second device in other directions, so that the accuracy of the total interference information of the first satellite determined by the first device is higher.

[0009] In a possible implementation, the first device can further send a first request to the second device, and the first request is used to request the interference information. The first request can include one or more of the following: the first time point, a first period used to indicate the frequency of reporting the interference information, a first position of the first satellite, or ephemeris information of the first satellite. In this technical solution, the parameters included in the first request are only examples, and the first request can further include more or fewer parameters.

[0010] In a possible implementation, the first request includes the first position, and before sending the first request to the second device, the first device can further determine the first position based on the ephemeris information of the first satellite. In this technical solution, the first device determines the first position of the first satellite based on the ephemeris information of the first satellite, and sends the first position to the second device, which can reduce the transmission overhead of the first request compared with sending the ephemeris information of the first satellite to the second device.

[0011] In a possible implementation, the first request includes the first direction, and before sending the first request to the second device, the first device can further determine the first position based on the ephemeris information of the first satellite, and determine the first direction based on the first position and a second position of the second device. In this technical solution, the first device determines the first direction based on the ephemeris information of the first satellite and the position of the second device, and sends the first direction to the second device, which can reduce the signaling overhead of the first request compared with sending the ephemeris information of the first satellite to the second device. In addition, the first information sent by the second device to the first device can only include the interference information in the first direction, which helps to reduce the signaling overhead of the first information.

[0012] In a possible implementation, the first information includes an association between the interference information and the first time and / or the first direction. In this technical solution, the content included in the first information is related to the parameter included in the first request. For example, if the first request includes the first time and / or the first period, the first information includes the association between the direction and the interference information; if the first request includes the first direction and the first time or the first period, the first information includes the interference information; if the first request includes the first direction, the first information includes the association between the time and the interference information; if the first request includes the ephemeris information of the first satellite, the first information includes the association between the time, the direction and the interference information.

[0013] In a possible implementation, the first device can further send first strategy information to the second device when the total interference information is greater than an interference threshold, where the first strategy information is used to reduce the interference of the second device on the first satellite. In this technical solution, when the first device determines that the total interference information of the first satellite is greater than the threshold, the first device can send the first strategy information to the second device to reduce the interference of the second device on the first satellite, which helps to improve the service quality of the first satellite.

[0014] In a possible implementation, the interference threshold is related to the position of the first satellite. In this technical solution, the interference threshold is related to the position of the first satellite. For example, when the traffic volume in the coverage area of the first satellite is large, the total interference information that the first satellite can accept is low, and therefore a lower threshold can be set; when the traffic volume in the coverage area of the first satellite is small, the total interference information that the first satellite can accept is high, and therefore a higher threshold can be set, so that the service quality of the satellite and the service quality of the second device can be guaranteed at the same time as much as possible.

[0015] In a possible implementation, the first strategy information includes the maximum transmission power of the second device and / or first indication information; the first indication information is used to indicate that the beam direction of the second device is not directed to the first direction; or the first indication information is used to indicate that the null direction of the second device is the first direction. In this technical solution, reducing the maximum transmission power of the second device can reduce the radiation power of the second device in the first direction and reduce the interference information of the second device on the first satellite; indicating that the beam direction of the second device is not directed to the first direction makes the transmission beam of the second device avoid the direction in which the first satellite is located, which helps to reduce the probability that the second device interferes with the first satellite; indicating that the second device adjusts the null direction to be the first direction can reduce the interference information on the first satellite without reducing the transmission power of the second device, so that the service quality of the satellite and the service quality of the second device can be guaranteed at the same time as much as possible.

[0016] In a possible implementation, the first satellite is a satellite with the highest priority in a first satellite set, and the first satellite set includes satellites with the same working frequency band as the second device. In this technical solution, the first satellite is a satellite with the highest priority in the first satellite set, and the first device can instruct the null direction of the second device to be the direction of the first satellite relative to the second device, thereby preferentially guaranteeing the service quality of the first satellite.

[0017] In a possible implementation, the first indication information is further used to instruct the null direction to point to the first satellite. In this technical solution, when the first satellite is a satellite with the highest priority, the first device can instruct the null direction of the second device to change with the position of the first satellite, that is, the null direction of the second device always points to the first satellite, thereby reducing the interference of the second device on the first satellite and improving the service quality of the first satellite on the basis of guaranteeing the service quality of the second device.

[0018] In a possible implementation, the first device can further receive a second request from a third device, and the second request is used to request total interference information of the first satellite, and the second request includes ephemeris information of the first satellite. In this technical solution, the third device (for example, a satellite management system) can request the first device to acquire the total interference information of the first satellite, and automatically manage the interference information of the second device on the first satellite on the basis of the total interference information, thereby reducing manual operation and improving the supervision efficiency of the total interference information of the first satellite.

[0019] In a possible implementation, the second request further includes one or more of the following: priority information of the first satellite, an interference threshold, an association relationship between the first time or the first position and the interference threshold, the first position being the position of the first satellite, or a working frequency band of the first satellite. In this technical solution, the parameters included in the second request are only examples, and the second request can further include more or fewer parameters.

[0020] In a possible implementation, the first device can further send second information to the third device when the total interference information is greater than the interference threshold, and the second information is used to prompt that the total interference information is greater than the interference threshold. In this technical solution, when the total interference information of the first satellite is greater than the interference threshold, a prompt information can be output, so that the third device can acquire the total interference received by the first satellite in a timely manner.

[0021] In a second aspect, a satellite interference information determination method is provided, which can be performed by a second device, which can be a ground access network device or a component in the ground access network device, etc. Taking the second device as the ground access network device for example, the method comprises: sending first information to a first device, the first information comprising interference information of the second device to a first satellite in a first direction at a first time, the first direction being used to indicate a direction of the first satellite relative to the second device.

[0022] In a possible implementation, the second device can further receive a first request from the first device, the first request being used to request the interference information; wherein the first request comprises one or more of the following: the first time; a first period, the first period being used to indicate a frequency of reporting the interference information; a first location or the first direction, the first location being a location of the first satellite; or ephemeris information of the first satellite.

[0023] In a possible implementation, the first information comprises an association between the interference information and the first time and / or the first direction.

[0024] In a possible implementation, the second device can further receive first policy information from the first device, the first policy information being used to reduce interference of the second device to the first satellite.

[0025] In a possible implementation, the first policy information comprises a maximum transmission power of the second device and / or first indication information; the first indication information being used to indicate that a beam direction of the second device is not directed to the first direction; or the first indication information being used to indicate that a null direction of the second device is the first direction.

[0026] In a possible implementation, the first policy information comprises the first indication information, and the second device can further adjust the beam direction based on the first indication information; or adjust the null direction based on the first indication information.

[0027] In a possible implementation, the first indication information is further used to indicate that the null direction is directed to the first satellite.

[0028] In a third aspect, a method for determining satellite interference information is provided, which can be performed by a third device. The third device can be a management service consumer or a component in the management service consumer. The management service consumer can be a server of a satellite management system (e.g., a satellite management bureau) or the like network device, which is not limited in the embodiments of the present application. Taking the third device as a management service consumer for example, the method comprises: sending a second request to a first device, the second request being used for requesting total interference information of a first satellite, and the second request comprising ephemeris information of the first satellite.

[0029] In a possible implementation, the second request further comprises one or more of the following: priority information of the first satellite; an interference threshold; an association between the first time or the first location and the interference threshold, the first location being a location of the first satellite; or an operating frequency band of the first satellite.

[0056] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. The embodiments of the present application can be applied to various mobile communication systems, such as a new radio (NR) system, a long term evolution (LTE) system, an advanced long term evolution (LTE-A) system, a future communication system, and other communication systems, without limitation. For the convenience of understanding, some terms in the embodiments of the present application will be explained below.

[0057] For the convenience of understanding, some terms in the embodiments of the present application will be explained below.

[0058] (1) Managed object.

[0059] A managed object is used to describe information of a managed object or a management task in a management system. A managed object information model can be used as an interaction parameter in a management interface. Creating a managed object represents creating management information in a management system, and enables the management system to manage a managed object or perform a management task according to the management information. In the embodiments of the present application, a managed object can include a network device in a network, such as a network function (NF) or a network element (NE). For example, the managed object can be an access network device (for example, a base station) in a radio access network (RAN).

[0060] (2) Management service consumer and management service provider.

[0061] The management service producer (MnS producer) refers to an entity for providing a management service (MnS), and the management service consumer (MnS consumer) refers to an entity for using the management service. The management service consumer can obtain the management service function provided by the corresponding management service producer by invoking the management service. In the embodiments of the present application, the management service producer is referred to as a management function (MnF) entity, and the management service consumer can be a third-party network management system, for example, a satellite management system.

[0062] (3) Management function.

[0063] The MnF refers to an entity for providing a specific network or service management capability. FIG. 1 shows the logical architecture of the MnF. As shown in the figure, the MnF can provide the MnS provided by the MnF to the MnS consumer (such as a third-party network management system or other MnF) for use as the MnS producer (as shown by the line with a hollow circle at one end in FIG. 1); or the MnF can also invoke the MnS provided by other MnF as the MnS consumer (as shown by the line with a semicircular arc at one end in FIG. 1). The MnF invokes the MnS of other MnF based on a service-oriented interface.

[0064] (4) Null direction: refers to the performance of the antenna in some directions due to problems in the design or installation of the antenna, that is, the radiation power of the antenna in some directions is lower than that in other directions, and the some directions are the null directions.

[0065] (5) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" refers to one or more, and "more" refers to two or more. And / or describes the association relationship between the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. At least one (or similar expressions) refers to any combination of these items, including any combination of single item (or) or multiple items. For example, at least one of a, b, or c can represent a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

[0066] Unless otherwise defined, the examples in the present application refer to "first", "second" and the like for distinguishing between similar objects, not necessarily described in a chronological order, nor in sequence of importance or priority.

[0067] In addition, the terms "comprising" and "having" in the embodiments of the present application and the claims and drawings are not exclusive. For example, a process, method, system, product or device that includes a series of steps or modules is not limited to the listed steps or modules, and can also include steps or modules that are not listed.

[0068] When the ground access network equipment shares the spectrum with the satellite, that is, the ground access network equipment uses the satellite frequency band, the power radiated by the ground access network equipment can interfere with the satellite and affect the service quality of the satellite. For example, referring to FIG. 2, which is a schematic diagram of interference of the ground access network equipment to the satellite, as shown in FIG. 2, when the device 1 performs data transmission with the satellite, if the access network equipment uses the satellite frequency band, the power radiated by the access network equipment can interfere with the satellite and affect the service quality of the satellite. The device 1 can be an access network equipment or a terminal device. Therefore, in order to protect the service quality of the satellite, it is necessary to monitor the total interference information (or also referred to as total interference data) of the ground access network equipment to the satellite.

[0069] At present, the process of collecting the total interference information of the ground access equipment to the satellite is as follows:

[0070] S1: The management service consumer (for example, the satellite management system) sends a request to the management service provider to request to create a managed object instance (MOI).

[0071] S2: The MnS producer collects data according to the MOI attribute requirements.

[0072] The data collection approach of the MnS producer includes the following two kinds:

[0073] The first kind is that the MnS producer collects associated data based on the management data collection (ManagementDataCollection) information object class (IOC), and the data attributes collected may include, for example, management data (ManagementData), target node filter (targetNodeFilter), collection time window (collectionTimeWindow) and data scope (dataScope).

[0074] The second, the MnS producer collects performance metrics based on a performance metric collection task (PerfMetricJob) IOC implementation. The collected data can include, for example, performance metrics, object instances, and the like.

[0075] S3: The MnS producer sends the collected data to the MnS consumer.

[0076] The MnS consumer can determine the total interference information of the ground access network device to the satellite based on the data.

[0077] The MnS producer collects data based on fixed attribute information, and the radiation power of the ground access network device collected by the MnS producer is currently at the cell granularity, that is, the maximum or minimum transmission power of the cell corresponding to the load. In this way, regardless of the position of the satellite, the interference information (such as interference power) of the collected ground access network device to the satellite is the same, and the interference power of the collected ground access network device to all satellites is also the same. That is, the accuracy of the interference power of the collected ground access network device to the satellite based on the current method is low, which is not conducive to the supervision of the MnS producer on the interference situation of the satellite.

[0078] Therefore, in order to improve the accuracy of the collected interference information of the ground access network device to the satellite, the embodiments of the present application provide a satellite interference information determination method. In the method, the second device (for example, a ground access network device) can send interference information in a specified direction of the second device to the first device (for example, an MnS producer). In this way, when determining the total interference information of the ground access network device to the satellite, the MnS producer uses interference information of each ground access network device to the satellite only including interference information in the direction of each ground access network device pointing to the satellite, and does not include interference information in other directions, so that the accuracy of the determined total interference information is higher.

[0079] Please refer to FIG. 3, which is a system architecture diagram provided by the embodiments of the present application, and the system architecture can also be referred to as a network management system architecture, and the like. The system architecture includes a management service consumer, a management service provider, and a network element. The management service provider includes a cross-domain management function unit and a domain management function unit. The following will briefly introduce each unit.

[0080] (1) Management service consumer.

[0081] A management service consumer is used to request invocation of management services. For example, a management service consumer can initiate a management service invocation request to a management domain (e.g., including a cross-domain management unit or a single-domain management unit). One example of a management service consumer is a 3rd party entity, e.g., a vertical industry management system, which can initiate a management service invocation request to a management domain (cross-domain management system or single-domain management system).

[0082] (2) Cross-domain management function unit.

[0083] A cross-domain management function unit, which can also be referred to as a network management function (NMF) or a network management system (NMS). One cross-domain management function unit can manage one or more domain management function units.

[0084] (3) Domain management function unit.

[0085] A domain management function unit, which can also be referred to as a single-domain management function unit or a single-domain management system (EMS). A domain management function unit includes, for example, a subnetwork management function (NMF), a network element / function management function, a RAN domain management function unit, or a core network domain management function unit. One domain management function unit can manage one or more network elements.

[0086] (4) Network element.

[0087] A network element is an entity providing network services, including a radio access network element, a core network element (not shown in the figure), a transport network element (not shown in the figure), and the like. For example, the core network element can include, but is not limited to, an access and mobility management function (AMF) entity, a session management function (SMF) entity, a policy control function (PCF) entity, a user plane function (UPF) entity, a network data analysis function (NWDAF) entity, a network repository function (NRF) entity, a gateway, and the like.

[0088] The radio access network element can include, but is not limited to, various types of base stations (for example, a generation node B (gNB), an evolved Node B (eNB), a central unit control panel (CU-CP), a central unit (CU), a distributed unit (DU), a central unit user panel (CU-UP), and the like). In different systems, the CU (or CU-CP and CU-UP) and DU can also have different names, but those skilled in the art can understand their meanings. For example, in an open RAN (ORAN) system, the CU can also be referred to as an O-CU, the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, and the CU-UP can also be referred to as an O-CU-UP.

[0089] The naming of each unit in FIG. 3 is only an example, and the application does not limit the name of each unit in FIG. 3. In the embodiments of the application, optional steps are indicated by dashed lines.

[0090] The satellite interference information determination method provided by the embodiments of the application will be described in detail below in combination with the system architecture shown in FIG. 3.

[0091] Please refer to FIG. 4, which is a flowchart of a satellite interference information determination method provided by an embodiment of the application. The method can be implemented by a first device, for example, the management service provider in FIG. 3, and a second device, for example, the access network element shown in FIG. 3. The implementation process includes the following steps:

[0092] S401: The second device sends first information to the first device. Correspondingly, the first device receives the first information.

[0093] The first information comprises interference information (e.g., first interference information) of the second device to the first satellite in the first direction at the first time, and the first direction is the direction of the first satellite relative to the second device. Optionally, the interference information can be the radiation power, i.e., the interference information of the second device to the first satellite in the first direction at the first time can be understood as the power radiated by the second device in the first direction at the first time. In the embodiments of the present application, the interference information is taken as an example of power.

[0094] Optionally, the content carried by the first information can include the following forms:

[0095] Form 1: The first interference information.

[0096] Form 2: The association relationship between the first interference information and the first time. For example, the first information comprises a first list, the first list comprises at least one time and at least one interference information, each time in the at least one time corresponds to one interference information, and the at least one time comprises the first time. The first device can determine the first interference information corresponding to the first time from the first list. The first list can be referred to as Table 1, and Table 1 takes an example that the at least one time comprises n times.

[0097] Table 1

[0098] Form 3: The association relationship between the first interference information and the first direction. For example, the first information comprises a second list, the second list comprises at least one direction and at least one interference information, each direction in the at least one direction corresponds to one interference information, and the at least one direction comprises the first direction. The first device can determine the first interference information corresponding to the first direction from the second list. The second list can be referred to as Table 2, and Table 1 takes an example that the at least one direction comprises m directions.

[0099] Table 2

[0100] In Table 2, the direction range corresponding to the m directions comprises the full orientation of the second device, i.e., 360 degrees. For example, the second device can determine the angle region of the same beam radiation as one direction.

[0101] Form 4: the first interference information is associated with the first direction and the first time. For example, the first information includes a third list, the third list includes at least one direction, at least one time, and at least one interference information, each time in the at least one time is associated with one or more directions in the at least one direction, and one direction associated with one time corresponds to one interference information, the at least one time includes the first time, and the at least one direction includes the first direction. The first device can determine the first interference information corresponding to the first direction at the first time from the third list. The third list can refer to Table 3-Table 5, for example, Table 3 takes the at least one time includes one time and the at least one direction includes m directions as an example; Table 4 takes the at least one time includes n times and the at least one direction includes m directions as an example; Table 5 takes the at least one time includes k times as an example.

[0102] Table 3

[0103] Table 4

[0104] In Table 3 and Table 4, the direction range corresponding to the m directions includes the full orientation of the second device, i.e. 360 degrees. For example, the second device can determine the angle region of the same beam radiation as a direction.

[0105] Table 5

[0106] Optionally, before performing S401, the method further includes S402: the first device sends a first request to the second device. Correspondingly, the second device receives the first request. The first request is used to request interference information. Wherein, the first request can include one or more of the following: the first time; or, the first period; or, the first position or the first direction; or, the ephemeris information of the first satellite. Wherein, the first period is used to indicate the frequency of reporting interference information; the first position is the position of the first satellite, which can include the longitude, latitude and altitude of the first satellite, or the first position can also include the azimuth and elevation angle of the first satellite, etc.; the first direction is the direction of the first satellite relative to the second device, which can be an inclination angle, or can be an inclination angle range, for example, 0-30 degrees, or 60-90 degrees, etc.; the ephemeris information of the first satellite can include the identification and orbit information of the first satellite, etc., and the orbit information can include the orbit on which the first satellite runs, and the position on the orbit at each time, etc.

[0107] Optionally, the form of the content carried by the first information in S401 is related to the information included in the first request sent by the first device to the second device in S402.

[0108] For example, if the first request comprises a first time point, the first request can be used to request the second device to report interference information at the first time point. At this time, since the second device does not know the direction information of the first satellite relative to the second device, the second device can collect interference information of the second device at at least one direction at the first time point, and send the interference information corresponding to the at least one direction to the first device, that is, the content carried by the first information is in the form 3.

[0109] If the first request comprises a first period, the first request can be used to request the second device to report interference information according to the first period. At this time, since the second device does not know the direction information of the first satellite relative to the second device, the second device can collect interference information of the second device at multiple directions according to the first period, and send the interference information corresponding to the multiple directions to the first device according to the first period, that is, the content carried by the first information is in the form 3. Alternatively, the second device can also collect interference information of the second device at multiple directions according to a second period, and the second period is less than the first period, that is, the frequency of collecting interference information by the second device is greater than the frequency of reporting interference information by the second device, so that the second device can report interference information of the second device at multiple directions at multiple time points each time, that is, the content carried by the first information is in the form 4, for example, in the form shown in Table 4 in the form 4. In the embodiment of the present application, when the first request comprises the first period, the frequency of collecting interference information by the second device is the same as the frequency of reporting interference information by the second device.

[0110] Alternatively, since the first request only comprises the frequency information of reporting interference information, and does not comprise the related information of the starting time point of the period, the first information can also carry the information of the collection time point of the interference information, for example, when the second device receives the first request and first sends the first information to the first device, the first information can carry the information of the collection time point of the interference information, that is, the content carried by the first information is in the form 4, for example, in the form shown in Table 3 in the form 4.

[0111] If the first request comprises a first position, the second device can determine the direction of the first satellite (i.e., the first direction) according to the first position and its own position (e.g., the second position), at this time, the second device can collect interference information of the second device at the first direction at at least one time point, and send the interference information corresponding to the at least one time point to the first device, that is, the content carried by the first information is in the form 2.

[0112] If the first request comprises a first direction, the second device can collect interference information of the second device at the first direction at at least one time point, and send the interference information corresponding to the at least one time point to the first device, that is, the content carried by the first information is in the form 2.

[0113] If the first request comprises the ephemeris information of the first satellite, the second device can determine the position of the first satellite at each time according to the ephemeris information (for example, the orbit information in the ephemeris information), the first satellite can determine the direction of the first satellite at each time relative to the second device according to the position of the first satellite at each time, and thus the second device can only collect the interference information of the second device in the direction of the first satellite relative to the second device at each time when collecting the interference information corresponding to each time, that is, each time is only associated with one direction. For example, the second device determines that the position of the first satellite at the first time is the first position according to the ephemeris information of the first satellite, and at this time, the second device can determine that the direction of the first satellite relative to the second device is the first direction according to the first position and the second position, that is, determine that the direction of the first satellite relative to the second device at the first time is the first direction, and thus the second device can only collect the interference information of the second device in the first direction when collecting the interference information corresponding to the first time, that is, the first time is only associated with the first direction. Therefore, the second device can send the association relationship between the time and / or direction and the interference information, that is, the content carried by the first information can be in the above form 2, or the content carried by the first information can also be in the above form 3, or the content carried by the first information can also be in the above form 4, for example, the form shown in Table 5 in form 4.

[0114] If the first request comprises the first time and the first period, the first request can be used to request the second device to report the interference information according to the first period starting from the first time, and at this time, since the second device does not know the direction information of the first satellite relative to the second device, the second device can collect the interference information of the second device in multiple directions according to the first period starting from the first time, and send the interference information corresponding to the multiple directions to the first device, that is, the content carried by the first information is in the above form 3.

[0115] If the first request comprises the first time and the first position, at this time, the second device can determine the first direction according to the first position and the second position, the second device can only collect the interference information of the second device in the first direction at the first time (that is, the first interference information), and send the first interference information to the first device, that is, the content carried by the first information is in the above form 1.

[0116] If the first request comprises the first time and the first direction, the second device can only collect the interference information of the second device in the first direction at the first time (that is, the first interference information), and send the first interference information to the first device, that is, the content carried by the first information is in the above form 1.

[0117] If the first request includes the first time and the ephemeris information of the first satellite, the second device can determine the position of the first satellite at the first time (i.e., the first position) according to the ephemeris information, and determine the first direction according to the first position and the second position, and the second device can only collect the interference information (i.e., the first interference information) of the second device in the first direction at the first time, and send the first interference information to the first device, i.e., the content carried by the first information is the above form 1.

[0118] If the first request includes the first period and the first position, the second device can determine the first direction according to the first position and the second position, and collect the interference information of the second device in the first direction according to the first period, and send the collected interference information to the first device according to the first period, i.e., the content carried by the first information is the above form 1.

[0119] Optionally, since the first request only includes the frequency information of the reported interference information and the position information of the first satellite, and does not include the related information of the period starting time, the first information can also carry the information of the collection time of the interference information, for example, when the second device receives the first request and first collects the interference information, the first information can carry the information of the collection time of the interference information, i.e., the content carried by the first information is the above form 2.

[0120] If the first request includes the first period and the first direction, the first request can be used to request the second device to report the interference information in the first direction according to the first period, so the second device can collect the interference information of the second device in the first direction according to the first period, and send the collected interference information to the first device according to the first period, i.e., the content carried by the first information is the above form 1.

[0121] Optionally, since the first request only includes the frequency information of the reported interference information and the direction information of the first satellite, and does not include the related information of the period starting time, the first information can also carry the information of the collection time of the interference information, for example, when the second device receives the first request and first collects the interference information, the first information can carry the information of the collection time of the interference information, i.e., the content carried by the first information is the above form 2.

[0122] If the first request comprises the first period and the ephemeris information of the first satellite, the second device can determine the position of the first satellite at each time according to the ephemeris information, and determine the direction of the first satellite at each time relative to the second device according to the position of the first satellite at each time and the second position. Taking the collection of the interference information at the first time as an example, the second device can determine the position of the first satellite at the first time as the first position according to the ephemeris information, and determine the direction of the first satellite at the first time relative to the second device as the first direction according to the first position and the second position, and the second device can only collect the interference information of the second device at the first time in the first direction. At this time, since the first device can determine the first direction of the first satellite at the first time relative to the second device according to the ephemeris information of the first satellite, the second device can only send the interference information, that is, the content carried by the first information can be the above form 1.

[0123] Optionally, since the first request only comprises the frequency information of the reported interference information and the ephemeris information of the first satellite, and does not comprise the related information of the period starting time, the first information can also carry the information of the collection time of the interference information, for example, when the second device receives the first request and first collects the interference information, the first information can carry the information of the collection time of the interference information, that is, the content carried by the first information is the above form 2.

[0124] If the first request comprises the first position and the ephemeris information of the first satellite, the second device can determine the time corresponding to the first position (for example, the first time) according to the first position and the ephemeris information of the first satellite, and determine the first direction according to the first position and the second position, at this time, the second device can only collect the interference information of the second device in the first direction at the first time (that is, the first interference information), and send the first interference information to the first device, that is, the content carried by the first information is the above form 1.

[0125] If the first request comprises the first direction and the ephemeris information of the first satellite, the second device can determine the position of the first satellite (for example, the first position) according to the first direction and the second position, and determine the time corresponding to the first position (for example, the first time) according to the first position and the ephemeris information of the first satellite, at this time, the second device can only collect the interference information of the second device in the first direction at the first time (that is, the first interference information), and send the first interference information to the first device, that is, the content carried by the first information is the above form 1.

[0126] If the first request comprises the first time, the first period and the first position, the second device can determine the direction of the first satellite relative to the second device (i.e. the first direction) according to the first position and the second position, and the second device can collect the interference information of the second device in the first direction according to the first period starting from the first time, and send the collected interference information to the first device according to the first period, i.e. the content carried by the first information is in the above form 1.

[0127] If the first request comprises the first time, the first period and the first direction, the second device can collect the interference information of the second device in the first direction according to the first period starting from the first time, and send the collected interference information to the first device according to the first period, i.e. the content carried by the first information is in the above form 1.

[0128] If the first request comprises the first time, the first period and the ephemeris information of the first satellite, the second device can determine the position of the first satellite at each time according to the ephemeris information, and determine the direction of the first satellite relative to the second device at each time according to the position of the first satellite at each time and the second position. Taking the collection of the interference information at the first time as an example, the second device can determine the position of the first satellite at the first time as the first position according to the ephemeris information, and determine the direction of the first satellite relative to the second device at the first time as the first direction according to the first position and the second position, and the second device can only collect the interference information of the second device in the first direction at the first time. At this time, since the first device can determine the first direction of the first satellite relative to the second device at the first time according to the ephemeris information of the first satellite, the second device can only send the interference information, i.e. the content carried by the first information can be in the above form 1.

[0129] If the first request comprises the first period, the first position and the ephemeris information of the first satellite, the second device can determine the form of the content carried by the first information according to the first period and the first position, which can be referred to the related description of determining the form of the content carried by the first information when the first request comprises the first period and the first position, which will not be repeated here. Alternatively, the second device can also determine the form of the content carried by the first information according to the first period and the ephemeris information of the first satellite, which can be referred to the related description of determining the form of the content carried by the first information when the first request comprises the first period and the ephemeris information of the first satellite, which will not be repeated here.

[0130] If the first request comprises the first period, the first direction and the ephemeris information of the first satellite, the second device can determine the form of the content carried by the first information according to the first period and the first direction, which can refer to the description of determining the form of the content carried by the first information when the first request comprises the first period and the first direction, and details are not described herein. Alternatively, the second device can also determine the form of the content carried by the first information according to the first period and the ephemeris information of the first satellite, which can refer to the description of determining the form of the content carried by the first information when the first request comprises the first period and the ephemeris information of the first satellite, and details are not described herein.

[0131] If the first request comprises the first time, the first period, the first position or the first direction, and the ephemeris information of the first satellite, since the first device can determine the collection time and direction corresponding to the interference information reported by the second device each time based on the information carried in the first request, the content carried by the first information is the above form 1.

[0132] Optionally, if the first request comprises the first position, the first device can also determine the first position according to the ephemeris information of the first satellite before sending the first request to the second device; if the first request comprises the first direction, the first device can also determine the position of the first satellite (i.e. the first position) according to the ephemeris information of the first satellite before sending the first request to the second device, and determine the first direction according to the first position and the second position.

[0133] S403: The first device determines the total interference information of the first satellite based on the first information.

[0134] The total interference information of the first satellite comprises the interference information of the first satellite from a plurality of second devices. Optionally, the first device can receive the first information from a plurality of second devices, and the first device can determine the interference information of the first satellite from each second device according to the first information of each second device, and determine the total interference information of the first satellite based on the interference information of the first satellite from each second device. For example, the first device can directly add the interference information corresponding to the plurality of second devices to obtain the total interference information of the first satellite; or the first device can also determine the weight corresponding to each second device according to the distance between each second device and the first satellite, and take the value obtained by weighted summation or weighted average of the interference information corresponding to the plurality of second devices as the total interference information of the first satellite.

[0135] After the first device obtains the total interference information of the first satellite, it can determine whether the total interference information is greater than an interference threshold. If the total interference information of the first satellite is greater than the interference threshold, it indicates that the first satellite is interfered more and has a lower service quality, and thus the interference of the plurality of second devices on the first satellite needs to be reduced. If the total interference information of the first satellite is less than or equal to the interference threshold, it indicates that the first satellite is interfered less and has a higher service quality, and thus the interference of the plurality of second devices on the first satellite can not be adjusted.

[0136] Optionally, the interference threshold can be related to the position of the first satellite. For example, if the first satellite is at a position where the service quantity of the coverage area thereof is large, in order to ensure the service quality of the first satellite, the total interference acceptable by the first satellite is lower, and thus the interference threshold corresponding to the position can be smaller. If the first satellite is at a position where the service quantity of the coverage area thereof is small, the total interference acceptable by the first satellite can be higher, and thus the interference threshold corresponding to the position can be larger.

[0137] Optionally, when the total interference information of the first satellite is greater than the interference threshold, the interference of the plurality of second devices on the first satellite needs to be reduced, and thus after S403 is performed, the method further includes S404-S406.

[0138] S404: The first device sends second information to a third device. Correspondingly, the third device receives the second information. The second information is used to prompt that the total interference information of the first satellite is greater than the interference threshold.

[0139] The third device is, for example, a management service consumer in FIG. 3. After the third device receives the prompt information, it can send request information to the first device, used to request the first device to reduce the total interference on the first satellite, and after the first device receives the request, it can perform S404. It can be understood that after the third device receives the prompt information, it can also not send information to the first device, and the first device can directly perform S405, and the embodiments of the present application do not limit this.

[0140] S405: The first device sends first policy information to a second device. Correspondingly, the second device receives the first policy information. The first policy information is used to reduce the interference of the second device on the first satellite.

[0141] In S401, it is introduced that the interference information can be power, and reducing the interference of the second device to the first satellite can also be understood as reducing the power radiated by the second device to the first satellite. Among them, reducing the power radiated by the second device to the first satellite may, for example, be reducing the maximum transmit power of the second device, so as to reduce the radiation power of the second device in all directions (for example, the aforementioned omnidirectional), or it can also only reduce the radiation power of the second device in the first direction, while the radiation power of the second device in other directions remains unchanged. Therefore, optionally, the first strategy information can include the maximum transmit power of the second device and / or the first indication information. Among them, the first indication information is used to indicate that the beam direction of the second device is not directed to the first direction, or the first indication information is used to indicate that the null direction of the second device is the first direction.

[0142] In some embodiments, the first device can monitor the total interference information of multiple satellites, so the content included in the first strategy information can also be related to the priority of the satellite, for example, the first satellite is the satellite with the highest priority in the first satellite set, indicating that the service quality of the first satellite needs to be prioritized, so when the total interference information of the first satellite is greater than the interference threshold, the first strategy information can include the first indication information. If the first satellite is not the satellite with the highest priority in the first satellite set, it indicates that the service quality of other satellites needs to be prioritized, so when the total interference information of the first satellite is greater than the interference threshold, the first strategy information can not include the first indication information. If the first satellite is not the satellite with the highest priority in the first satellite set, and only the total interference information of the first satellite in the first satellite set is greater than the interference threshold, the first strategy information can include the first indication information. Among them, the satellites included in the first satellite set have the same working frequency band as the second device.

[0143] Optionally, if the first satellite is the satellite with the highest priority in the first satellite set, and the first indication information included in the first strategy information indicates that the null direction of the second device is the first direction, the first indication information can also indicate that the null direction of the second device changes with the movement of the first satellite, that is, the null direction of the second device always points to the first satellite.

[0144] The total interference information of the first satellite in S403 includes interference information of multiple second devices to the first satellite, and therefore, the first strategy information sent by the first device to different second devices can be different. For example, there are two second devices (device 1 and device 2) that interfere with the first satellite, wherein device 1 is far away from the first satellite, and the interference information of device 1 has a small influence on the first satellite; device 2 is close to the first satellite, and the interference information of device 2 has a large influence on the first satellite. Therefore, if the first strategy information includes the maximum transmission power, the maximum transmission power included in the first strategy information sent by the first device to device 1 can be large, and the maximum transmission power included in the first strategy information sent by the first device to device 2 can be small; or the first device can only instruct device 2 to reduce the interference to the first satellite, that is, the first device only sends the first strategy information to device 2, and does not send the first strategy information to device 1.

[0145] S404 and S405 can be executed simultaneously, or S404 can be executed before S405, or S404 can be executed after S405, and the embodiments of the present application do not limit this.

[0146] S406: The second device adjusts the maximum transmission power, the beam direction or the null direction of the second device based on the first strategy information.

[0147] For example, if the first strategy information includes the maximum transmission power, the second device can adjust the maximum transmission power of the second device to the maximum transmission power carried in the first strategy information; if the first strategy information includes the first indication information, and the first indication information indicates that the beam direction of the second device is not directed to the first direction, the second device can re-adjust the beam direction, and the adjusted beam direction is not directed to the first direction; if the first strategy information includes the first indication information, and the first indication information indicates that the null direction of the second device is the first direction, the second device can adjust the null direction, and the adjusted null direction is the first direction.

[0148] Optionally, the method can further include S407: The third device sends a second request to the first device. Correspondingly, the first device receives the second request. The second request is used to request the total interference information of the first satellite.

[0149] The ephemeris information of the first satellite is included in the second request. Optionally, the second request can further include one or more of the following: priority information of the first satellite; or an interference threshold; or an association relationship between the first time or the first location and the interference threshold; or a working frequency band of the first satellite.

[0150] The S407 can be performed before the S402, or the S407 can also be performed before the S404 or the S405, and the embodiments of the present application do not limit the execution timing of the S406. FIG. 4 takes the S407 performed before the S402 as an example.

[0151] In the embodiments of the present application, when the first device determines the total interference information of the first satellite, the interference information used is the interference information of the second device in the first direction, and does not include the interference information of the second device in other directions, so that the accuracy of the total interference information of the first satellite determined by the first device is higher. In addition, the first device can send policy information to the second device to adjust the interference of the second device to the first satellite, which helps to improve the service quality of the first satellite.

[0152] Several embodiments are introduced below through FIG. 5 to FIG. 7, which are several examples of the satellite interference information determination method introduced in the embodiment shown in FIG. 4. In these examples, the first device is taken as the management service provider shown in FIG. 3, the second device is taken as the access network element shown in FIG. 3, and the third device is taken as the management service consumer shown in FIG. 3.

[0153] Please refer to FIG. 5, which is a flow chart of the first example of the satellite interference information determination method provided by the embodiment shown in FIG. 4.

[0154] S501: The management service consumer sends a second request to the cross-domain management function unit. Correspondingly, the cross-domain management function unit receives the second request.

[0155] The second request includes the ephemeris information of the first satellite, which can include, for example, the identifier of the first satellite and the orbital information of the first satellite, etc., wherein the orbital information of the first satellite can include, for example, the orbit on which the first satellite runs, and the position on the orbit at each time point, etc. Optionally, the second request can also include one or more of the following: the priority information of the first satellite; the interference threshold; the association relationship between the first time point or the first position and the interference threshold; the working frequency band of the first satellite, etc.

[0156] S502: The cross-domain management function unit determines the first access network element that interferes with the first satellite.

[0157] For example, the cross-domain management function unit can determine a plurality of access network elements with the same working frequency band as the first satellite according to the working frequency band of the first satellite in the second request, and determine the plurality of access network elements as the access network elements that interfere with the first satellite. The first access network element is included in the plurality of access network elements. In the embodiments of the present application, the cross-domain management function unit requests the interference information of the first access network element as an example.

[0158] S503: The cross-domain management function unit determines a first position of the first satellite at the first time according to the ephemeris information of the first satellite, and determines a first direction of the first satellite relative to the first access network element based on the first position.

[0159] For example, the cross-domain management function unit can determine the direction of the first satellite relative to the first access network element (i.e., the first direction) according to the first position and the position (e.g., the second position) of the first access network element.

[0160] S504: The cross-domain management function unit sends a first request to the first domain management function unit corresponding to the first access network element. Correspondingly, the first domain management function unit receives the first request. The first request includes the first time and the first direction.

[0161] Optionally, the first request further includes an identifier of the first access network element.

[0162] S505: The first domain management function unit sends the first request to the first access network element. Correspondingly, the first access network element receives the first request. The first request includes the first time and the first direction.

[0163] For example, the first domain management function unit can determine the first access network element according to the identifier of the first access network element included in the first request, and send the first request to the first access network element. The first request includes the first time and the first direction.

[0164] S506: The first access network element collects interference information of the first access network element in the first direction at the first time.

[0165] S507: The first access network element sends the interference information to the first domain management function unit. Correspondingly, the first domain management function unit receives the interference information.

[0166] For example, the first access network element can send first information including the interference information to the first domain management function unit.

[0167] S508: The first domain management function unit sends the interference information to the cross-domain management function unit. Correspondingly, the cross-domain management function unit receives the interference information.

[0168] For example, the first domain management function unit can send first information including the interference information to the cross-domain management function unit. Optionally, the first information further includes an identifier of the first access network element.

[0169] S509: The cross-domain management function unit determines total interference information of the first satellite based on the interference information.

[0170] The cross-domain management function unit determines more content of the total interference information of the first satellite based on the interference information. For details, refer to the description of S403, which will not be repeated here.

[0171] If the cross-domain management function unit determines that the total interference information of the first satellite is greater than the interference threshold, S510-S513 can be performed. If the cross-domain management function unit determines that the total interference information of the first satellite is less than or equal to the interference threshold, S510-S513 can not be performed. Therefore, S510-S513 are optional steps.

[0172] S510: The cross-domain management function unit sends second information to the management service consumer. Correspondingly, the management service consumer receives the second information. The second information is used to prompt that the total interference information of the first satellite is greater than the interference threshold.

[0173] After receiving the prompt information, the management service consumer can send request information to the cross-domain management function unit to request the cross-domain management function unit to reduce the total interference received by the first satellite. After receiving the request, the cross-domain management function unit can perform S511. It can be understood that the management service consumer can also not send information to the cross-domain management function unit after receiving the prompt information. The cross-domain management function unit can directly perform S511, which is not limited in the embodiments of the application.

[0174] S511: The cross-domain management function unit sends first policy information to the first domain management function unit. Correspondingly, the first domain management function unit receives the first policy information.

[0175] The first policy information is used to reduce the interference of the first access network element to the first satellite. Taking the interference information as power as an example, reducing the power radiated by the first access network element to the first satellite can be, for example, reducing the maximum transmit power of the first access network element, so as to reduce the radiation power of the first access network element in all directions (for example, the aforementioned omnidirectional), or it can only reduce the radiation power of the first access network element in the first direction, while the radiation power of the first access network element in other directions remains unchanged. Therefore, optionally, the first policy information can include the maximum transmit power of the first access network element and / or first indication information. The first indication information is used to indicate that the beam direction of the first access network element is not directed to the first direction, or the first indication information is used to indicate that the null direction of the first access network element is the first direction.

[0176] Optionally, the first policy information can further include information related to the priority of the first satellite. For example, the cross-domain management function unit can determine that the first satellite is the satellite with the highest priority in the first satellite set according to the priority information of the first satellite, which indicates that the quality of service of the first satellite needs to be prioritized, and thus the first policy information can include the first indication information. If the first satellite is not the satellite with the highest priority in the first satellite set, it indicates that the quality of service of other satellites needs to be prioritized, and thus the first policy information can not include the first indication information. If the first satellite is not the satellite with the highest priority in the first satellite set, and only the total interference information of the first satellite in the first satellite set is greater than the interference threshold, the first policy information can include the first indication information. The satellites included in the first satellite set have the same working frequency band as the first access network element.

[0177] Optionally, if the first satellite is the satellite with the highest priority in the first satellite set, and the first indication information included in the first policy information indicates that the null direction of the first access network element is the first direction, the first indication information can further indicate that the null direction of the first access network element changes with the movement of the first satellite, i.e., the null direction of the first access network element always points to the first satellite.

[0178] S512: The first domain management function unit sends the first policy information to the first access network element. Correspondingly, the first access network element receives the first policy information.

[0179] S513: The first access network element adjusts the maximum transmission power, the beam direction, or the null direction according to the first policy information.

[0180] The first access network element can adjust the maximum transmission power, the beam direction, or the null direction based on the first policy information. For example, if the first policy information includes the maximum transmission power, the first access network element can adjust the maximum transmission power to the maximum transmission power carried in the first policy information; if the first policy information includes the first indication information, and the first indication information indicates that the beam direction of the first access network element does not point to the first direction, the first access network element can re-adjust the beam direction, and the adjusted beam does not point to the first direction; if the first policy information includes the first indication information, and the first indication information indicates that the null direction of the first access network element is the first direction, the first access network element can adjust the null direction, and the adjusted null direction is the first direction.

[0181] In this technical solution, the cross-domain management function unit determines the first time and the first direction, so that the first information sent by the access network element can only include the interference information, which helps to reduce the transmission overhead of the access network element.

[0182] Referring to FIG. 6, a flowchart of a second example of a method for determining satellite interference information is provided for the embodiment shown in FIG. 4.

[0186] S603: The cross-domain management function unit determines the first period.

[0187] The cross-domain management function unit can subscribe to the interference information of the first access network element. For example, the cross-domain management function unit can subscribe to the interference information of the first access network element in all directions from the first access network element. Correspondingly, the first access network element can provide the subscribed interference information to the cross-domain management function unit.

[0188] Optionally, the first period can be related to the priority of the first satellite. For example, the higher the priority of the first satellite, the smaller the first period; if the priority of the first satellite is low, the first period is larger. Alternatively, the first period can also be related to the location of the first satellite, for example, the first period is related to the traffic volume of the coverage area when the first satellite is at the location. For example, the larger the traffic volume of the coverage area when the first satellite is at a certain location, the smaller the first period. If the traffic volume of the coverage area when the first satellite is at a certain location is smaller, the first period is larger.

[0189] S604: The cross-domain management function unit sends a first request to the first domain management function unit corresponding to the first access network element. Correspondingly, the first domain management function unit receives the first request. The first request includes the first period.

The first request includes the first period.

Optionally, the first information can also include time information, the list of the direction and interference information can be the list shown in Table 3, or the first information can include time information and the list of the direction and interference information (for example, the list shown in Table 2).

[0197] S608: The first domain management function unit sends the list of the direction and interference information to the cross-domain management function unit. Correspondingly, the cross-domain management function unit receives the list of the direction and interference information.

[0200] For example, the cross-domain management function unit can determine the first position of the first satellite at the first time according to the ephemeris information of the first satellite, and determine the direction of the first satellite relative to the first access network element (i.e. the first direction) according to the first position and the position (e.g. the second position) of the first access network element. The cross-domain management function unit can obtain the interference information corresponding to the first direction from the list.

[0201] S610: The cross-domain management function unit determines the total interference information of the first satellite based on the interference information.

[0202] S611: The cross-domain management function unit sends the second information to the management service consumer. Correspondingly, the management service consumer receives the second information. The second information is used to prompt that the total interference information of the first satellite is greater than the interference threshold.

[0207] In the technical solution, the cross-domain management function unit subscribes to the access network element to periodically report the omnidirectional interference information, which can reduce the signaling interaction between the management service provider and the first access network element, and help reduce the transmission overhead of the management service provider and the access network element.
