[0070] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0071] The key technology for constructing an integrated space-air-ground network and realizing the convergence of mobile and satellite communications lies in the management and research of NF (Network Function) elements on satellites. Deploying NF elements on satellites will give them mobility. Furthermore, satellites move rapidly; for example, the linear velocity of a satellite in geostationary orbit is approximately 3.1 km / s, and its trajectory is relatively fixed, predictable, and solvable. NF elements on satellites also possess this property.

[0072] Satellites operate at high speeds in orbit. When a satellite moves to the boundary of an NRF (Network Repository Function) management area and leaves, the network elements on the satellite will be idle, resulting in low utilization of the NF network elements. Therefore, this application provides a satellite network element registration management method to improve the aforementioned technical problem.

[0073] In one embodiment, the architecture of the satellite network element registration and management system is first described. Figure 1 The diagram shows the architecture of the satellite network element registration and management system. (For example...) Figure 1 As shown, the satellite network element registration and management system includes an NF network element 1 mounted on a satellite, a first NRF network element 2, a second NRF network element 3 on the ground, and a satellite control center 4. NF network element 1 is located on the satellite side, while the first NRF network element 2, the second NRF network element 3, and the satellite control center 4 are located on the ground side. The satellite control center 4 is connected to the first NRF network element 2 and the second NRF network element 3, and NF network element 1 is connected to the first NRF network element 2 and the second NRF network element 3.

[0074] Furthermore, the first NRF network element 2 corresponds to the first area and can be used to register and manage NF network elements entering the first area. The second NRF network element 3 corresponds to the second area and can be used to register and manage NF network elements entering the second area. Through the interaction between NF network element 1, the first NRF network element 2, the second NRF network element 3, and the satellite control center 4, the registration switching of NF network elements between the first NRF network element and the second NRF network element can be realized.

[0075] In the aforementioned satellite network element registration and management system architecture, by collaborating with the satellite control center through NRF network elements, satellite trajectories can be predicted and calculated in advance, and registration and switching can be completed quickly and promptly. This reduces the latency of NF network elements on the satellite during the switching process between different NRF network elements and avoids NF network elements being in an unsupervised and idle state, thereby improving the utilization rate of NF network elements on the satellite. At the same time, the satellite control center does not need to directly connect with NF network elements to obtain specific information about NF network elements, realizing the separation of management and control between the satellite control center and NF network elements, and improving the security of core network topology and information.

[0076] In one embodiment, Figure 2 This is a flowchart illustrating the first satellite network element registration management method in this application embodiment. The method is applied to... Figure 1 The first NRF network element in the method includes the following steps:

[0077] S201, upon detecting that a satellite is moving from the first area to the second area, the second NRF network element is determined based on the area identifier of the second area.

[0078] Optionally, the first region can be the region where the satellite is currently located; the second region can be the region where the satellite is to move to; and the second NRF network element can be a ground-based network element used to manage the second region. For example, there is a preset correspondence between region identifiers and NRF network elements. After determining that the satellite is to move to the second region, the second NRF network element corresponding to the second region can be determined based on the preset correspondence between region identifiers and NRF network elements.

[0079] Furthermore, there are many ways to identify a satellite moving from the first area to the second area. For example, one method could be that the NF network element on the satellite informs the first NRF network element that the satellite is moving from the first area to the second area. Another method could be to send a satellite movement subscription request to the satellite control center; wherein, the satellite movement subscription request is used to instruct the satellite control center to send a satellite movement notification when the satellite moves from the first area to the second area.

[0080] Furthermore, when the satellite control center detects that a satellite is about to move out of the management area of ​​the first NRF network element, the satellite control center will notify the first NRF network element that the satellite is moving and inform it of the second area the satellite is moving to. Subsequently, if the first NRF network element receives the satellite movement notification from the satellite control center, it can determine that the satellite has moved from the first area to the second area; wherein, the satellite movement notification includes the area identifier of the second area, which is determined by the satellite control center based on the constellation diagram and the satellite's movement trajectory. For example, the second area may specifically be determined by the satellite control center based on the basic logic of satellite orbit control, according to the constellation diagram and the satellite's movement trajectory.

[0081] Specifically, when the first NRF network element receives a satellite movement notification sent by the satellite control center, it determines that the satellite is moving from the first area to the second area, and determines the second NRF network element corresponding to the second area based on the area identifier of the second area included in the satellite movement notification and the preset correspondence between the area identifier of the area and the NRF network element.

[0082] S202, send the first network element information of the NF network element carried on the satellite to the second NRF network element.

[0083] Optionally, the NF network element carried on the satellite can be a network element used to register with a certain NRF network element in order to provide network services to the area corresponding to that NRF network element.

[0084] Optionally, when informing the first NRF network element that the satellite is moving, the satellite control center also sends the satellite's identifier to the first NRF network element. This identifier could include the satellite's identity or specific markings. In other words, the satellite movement notification includes the satellite identifier, which allows the first network element information of the NF network element mounted on the satellite to be determined. For example, the first network element information can be determined based on a pre-defined correspondence between the satellite identifier and the first network element information of the NF network element mounted on the satellite.

[0085] Furthermore, after the first NRF network element determines the first network element information of the NF network element carried on the satellite, it can send the first network element information to the second NRF network element.

[0086] S203, send a pre-registration request to the NF network element.

[0087] The pre-registration request instructs the NF network element to send a registration request to the second NRF network element. The registration request includes the second network element information of the NF network element. The first and second network element information are used by the second NRF network element to perform registration processing on the NF network element. Both the first and second network element information can include information such as network element identifier and network element type.

[0088] Furthermore, the pre-registration request includes the address information of the second NRF network element. The pre-registration request is used to instruct the NF network element to send a registration request to the second NRF network element based on the address information.

[0089] Optionally, when the first NRF network element detects that a satellite is moving from the first area to the second area, it sends the first network element information of the NF network element to the second NRF network element and sends a pre-deregistration request including the address information of the second NRF network element to the NF network element. After receiving the pre-deregistration request, the NF network element returns a pre-deregistration request response to the first NRF network element. At the same time, the NF network element also sends a registration request including the second network element information to the second NRF network element. After receiving the registration request, the second NRF network element determines the consistency comparison result based on the first network element information and the second network element information, and returns a registration request response to the NF network element based on the consistency comparison result.

[0090] It is understood that the pre-registration mechanism in this application can effectively reduce the latency and complexity of re-registration and addressing of NF network elements on the satellite, and improve the utilization rate of NF network elements on the satellite.

[0091] In the aforementioned satellite network element registration management method, by introducing a first NRF network element corresponding to the first region and a second NRF network element corresponding to the second region, when the satellite is detected moving from the first region to the second region, the first NRF network element sends first network element information to the second NRF network element and sends a pre-registration request to the NF network element. This allows the NF network element to send a registration request including second network element information to the second NRF network element, enabling the second NRF network element to register the NF network element based on the first and second network element information. This scheme, through the interaction between the first NRF network element corresponding to the first region, the second NRF network element corresponding to the second region, and the NF network element, enables rapid registration switching of the NF network element between the first and second NRF network elements. This reduces the latency of the NF network element on the satellite during switching between different NRF network elements and avoids the NF network element being in an unsupervised, idle state, thus improving the utilization rate of the NF network elements on the satellite.

[0092] It should be noted that, in order to facilitate the subsequent NF deregistration operation, it is also necessary to adjust the access priority of the NF network element in the first NRF network element, for example, by setting the access priority of the NF network element in the first NRF network element to the lowest level.

[0093] In one embodiment, based on the above embodiments, this application provides an optional method for determining first network element information. The first network element information includes network element type and network element identifier. Optionally, such as... Figure 3 As shown, the specific implementation process includes the following:

[0094] S301, based on satellite identifiers, determine the network element identifier in the first network element information according to the pre-built correspondence between satellite identifiers and network element identifiers.

[0095] Specifically, after the first NRF network element receives the satellite identifier of the satellite sent by the satellite control center, it determines the network element identifier corresponding to the satellite identifier based on the correspondence between the satellite identifier and the network element identifier.

[0096] S302, determine the network element type in the first network element information based on the network element identifier in the first network element information.

[0097] Specifically, after determining the network element identifier, the corresponding network element can be found in the network element database based on the network element identifier, and then the network element type to which the network element belongs can be determined.

[0098] It is understood that in this embodiment, the network element identifier and network element type can be obtained based solely on the satellite identifier to obtain the first network element information of the corresponding satellite. The process is simple and easy to operate, and it lays the foundation for the comparison operation of the second NRF network element.

[0099] In one embodiment, based on the above embodiments, this application provides an optional method for deleting registration information. Optionally, such as... Figure 4 As shown, the specific implementation process includes the following:

[0100] S401 receives a deregistration request sent by an NF network element.

[0101] The deregistration request includes the reason for deregistration and the network element identifier of the NF network element.

[0102] Optionally, the deregistration request can be a request sent by the NF network element to delete the registration information of the NF network element on the first NRF network element.

[0103] S402 If the reason for the registration failure is that the registration was already successful in the second NRF network element, then the registration information of the NF network element in the first NRF network element shall be deleted according to the network element identifier of the NF network element.

[0104] Optionally, if the reason for deregistration in the obtained deregistration request is that the NF network element has been successfully registered in the second NRF network element, the NF network element can be deregistered in the first NRF network element, that is, the registration information of the NF network element in the first NRF network element can be deleted according to the network element identifier of the NF network element.

[0105] It is understood that, in this embodiment, based on the pre-deregistration request sent to the NF network element, the NF network element can be registered in the second NRF network element and deregistered in the first NRF network element, thereby completing the registration and switching of the NF network element in a timely and rapid manner. This reduces the latency of the NF network element on the satellite during the switching process between different NRF network elements and avoids the NF network element being in an unsupervised and idle state, thereby improving the utilization rate of the NF network element on the satellite.

[0106] In one embodiment, Figure 5 This is a flowchart illustrating a second satellite network element registration management method provided according to an embodiment of this application. The method is applied to... Figure 1 The second NRF network element in the method includes the following steps:

[0107] S501 receives the first network element information of the NF network element carried on the satellite, transmitted by the first NRF network element.

[0108] Optionally, the first network element information is sent by the first NRF network element when it detects that the satellite is moving from the first area to the second area where the second NRF network element is located.

[0109] S502 receives registration requests sent by NF network elements.

[0110] Optionally, the registration request may include the second network element information of the NF network element.

[0111] Furthermore, the registration request can be sent by the NF network element to the second NRF network element after receiving a pre-registration request from the first NRF network element.

[0112] S503, based on the first network element information and the second network element information, performs registration processing on the NF network element.

[0113] Specifically, after the second NRF network element obtains the information of the first network element and the second network element, it performs registration processing on the NF network element based on the first network element information and the second network element information according to preset rules, and obtains the registration processing result.

[0114] Furthermore, the second NRF network element returns a registration request response to the NF network element based on the registration processing result. Specifically, it sends a registration request response to the NF network element; the registration request response can be either a registration success response or a registration failure response.

[0115] In the aforementioned satellite network element registration management method, by introducing a first NRF network element corresponding to the first region and a second NRF network element corresponding to the second region, it is possible to receive first network element information sent by the first NRF network element and a registration request including second network element information sent by the NF network element when the satellite is detected moving from the first region to the second region. The second NRF network element can then perform registration processing on the NF network element based on the first and second network element information. This scheme, through the interaction between the first NRF network element corresponding to the first region, the second NRF network element corresponding to the second region, and the NF network element, can quickly complete the registration switch of the NF network element between the first and second NRF network elements. This reduces the latency of the NF network element on the satellite during the switching process between different NRF network elements and avoids the NF network element being in an unsupervised and idle state, thus improving the utilization rate of the NF network elements on the satellite.

[0116] In one embodiment, based on the above embodiments, this application provides an optional method for registering NF network elements. Optionally, such as... Figure 6 As shown, the specific implementation process includes the following:

[0117] S601 performs a consistency comparison between the first network element information and the second network element information.

[0118] Optionally, both the first network element information and the second network element information include the network element type and the network element identifier. The first network element information is sent by the first NRF network element upon receiving a satellite movement notification from the satellite control center; wherein, the satellite movement notification is used to inform the first NRF network element that the satellite is moving from the first area to the second area; the second network element information is the information of the NF network element included in the registration request.

[0119] Specifically, the network element type and network element identifier included in the first network element information are compared with the network element type and network element identifier included in the second network element information for consistency.

[0120] S602, if the consistency comparison result is consistent, then register the NF network element on the second NRF network element.

[0121] Optionally, a registration request response can also be sent to the NF network element; wherein the registration request response is either a registration success response or a registration failure response.

[0122] Optionally, if the network element type included in the first network element information is consistent with the network element type included in the second network element information, and the network element identifier included in the first network element information is consistent with the network element identifier included in the second network element information, then the consistency comparison result is determined to be consistent, the NF network element can be registered on the second NRF network element, and a registration success response can be sent to the NF network element.

[0123] Furthermore, if the network element type included in the first network element information is inconsistent with the network element type included in the second network element information, and / or the network element identifier included in the first network element information is inconsistent with the network element identifier included in the second network element information, then the consistency comparison result is determined to be inconsistent, the NF network element registration process is restarted, and a registration failure response is sent to the NF network element.

[0124] It is understood that in this embodiment, the consistency comparison between the first network element information and the second network element information is used to determine whether to register the NF network element on the second NRF network element, thereby avoiding the registration of untrusted NF network elements and improving the security and reliability of NF network element registration.

[0125] In one embodiment, Figure 7 This is a flowchart illustrating a third satellite network element registration management method provided in an embodiment of this application, wherein the method is applied to Figure 1 The method includes the following steps: (The text appears to be incomplete and contains several grammatical errors. A more accurate translation would require the full context.)

[0126] S701 receives a pre-registration request sent by the first NRF network element.

[0127] Optionally, the pre-deregistration request is sent by the first NRF network element when it detects that the satellite is moving from the first area to the second area, and the pre-deregistration request includes the address information of the second NRF network element.

[0128] S702 sends a registration request to the second NRF network element based on the pre-registration request.

[0129] Optionally, the registration request includes the second network element information of the NF network element. The registration request is used for the second NRF network element to perform registration processing on the NF network element based on the first network element information and the second network element information. The first network element information is sent by the first NRF network element to the second NRF network element.

[0130] Furthermore, when the second NRF network element successfully registers the NF network element based on the information from the first and second network elements, the first NRF network element needs to deregister the NF network element. Specifically, a deregistration request is sent to the first NRF network element; the deregistration request includes the reason for deregistration and the network element identifier of the NF network element; the deregistration request is used by the first NRF network element to delete the registration information of the NF network element in the first NRF network element based on the network element identifier of the NF network element when it recognizes that the reason for deregistration is that the registration has been successfully completed in the second NRF network element.

[0131] Furthermore, since the pre-registration request includes the address information of the second NRF network element, the second NRF network element can be located based on its address information, and a registration request can be sent to that second NRF network element. Specifically, a registration request is sent to the second NRF network element based on its address information.

[0132] In the aforementioned satellite network element registration management method, by introducing a first NRF network element corresponding to the first region and a second NRF network element corresponding to the second region, it is possible to receive a pre-deregistration request sent by the first NRF network element when the satellite is detected moving from the first region to the second region. Then, the NF network element can send a registration request to the second NRF network element based on the pre-deregistration request, instructing the second NRF network element to register the NF network element according to the information of the first and second network elements. This scheme, through the interaction between the first NRF network element corresponding to the first region, the second NRF network element corresponding to the second region, and the NF network element, can quickly complete the registration switch of the NF network element between the first and second NRF network elements. This reduces the latency of the NF network element on the satellite during the switching process between different NRF network elements and avoids the NF network element being in an unsupervised, idle state, thus improving the utilization rate of the NF network elements on the satellite.

[0133] The following is through Figure 8-9 The entire process of satellite network element registration management is described. This satellite network element registration management method includes a preparation phase and an execution phase. Figure 8 A flowchart illustrating the preparation phase of the satellite network element registration management method. (Example) Figure 8 As shown, this is the process of interaction between the satellite control center and the first NRF network element. The preparation phase includes the following steps:

[0134] S801, the first NRF network element pre-builds the correspondence between satellite identifiers and network element identifiers.

[0135] S802, the first NRF network element sends a satellite mobile subscription request to the satellite control center.

[0136] The satellite mobile subscription request includes a satellite identifier.

[0137] S803: When the satellite control center detects that a satellite is moving toward the boundary of the first area, it determines the second area based on the constellation map and the satellite's movement trajectory.

[0138] S804, the satellite control center sends a satellite movement notification to the first NRF network element.

[0139] The satellite movement notification includes the area identifier of the second area and the satellite identifier of the satellite.

[0140] Figure 9 This is a flowchart illustrating the execution phase of the satellite network element registration management method. (Example:) Figure 9 As shown, this is the process of interaction between the NF network element, the first NRF network element, and the second NRF network element. The execution phase includes the following steps:

[0141] S901, the first NRF network element receives satellite movement notifications from the satellite control center.

[0142] The satellite movement notification includes the area identifier of the second area and the satellite identifier of the satellite.

[0143] S902, the first NRF network element determines the first network element information based on the satellite identifier, and determines the second NRF network element based on the area identifier of the second area.

[0144] S903, the first NRF network element sends the first network element information of the NF network element carried on the satellite to the second NRF network element.

[0145] The first network element information includes the network element type and the network element identifier.

[0146] S904, the first NRF network element adjusts the access priority of the NF network element in the first NRF network element.

[0147] S905, the first NRF network element sends a pre-registration request to the NF network element.

[0148] The pre-registration request includes the address information of the second NRF network element.

[0149] S906, the NF network element returns a pre-registration request response to the first NRF network element.

[0150] S907, the NF network element sends a registration request to the second NRF network element.

[0151] The registration request includes information about the second network element.

[0152] S908, the second NRF network element performs a consistency comparison between the information of the first network element and the information of the second network element.

[0153] S909, the second NRF network element returns a registration request response to the NF network element based on the consistency comparison result.

[0154] The registration request response can be either a registration success response or a registration failure response.

[0155] S910, when the registration request response is a registration success response, the NF network element sends a registration request to the first NRF network element.

[0156] S911, after the first NRF network element completes the deregistration with the NF network element, the first NRF network element returns a deregistration request response to the NF network element.

[0157] It should also be noted that if the registration request response is a registration failure response, the NF network element registration process will be restarted.

[0158] Through the above scheme, the interaction between the first NRF network element corresponding to the first area, the second NRF network element corresponding to the second area, and the NF network element can be quickly completed, thereby reducing the latency of the NF network element on the satellite during the switching process between different NRF network elements and avoiding the NF network element being in an unsupervised and idle state, thus improving the utilization rate of the NF network element on the satellite.
