Abstract
Description
Technical Field
[0001] This application relates to information determination technology in the field of communications, and more particularly to an information determination method, apparatus, device, computer storage medium, and computer program product. Background Technology
[0002] The 6th Generation Mobile Communication Technology (6G) network is a deeply integrated generation of networks, aiming for comprehensive, three-dimensional coverage. It leverages new capabilities across multiple dimensions, including communication, sensing, computing, and artificial intelligence (AI), to provide end-to-end information flow services. Distributed autonomy has become a key trend in the 6G core network. Based on the Distributed Autonomous Network (DAN) framework, new networks can be quickly assembled and automatically integrated into the overall 6G network, enabling autonomous operation and automatic sensing of environmental changes to adjust the network in real time. The Small Cloud Unit (SCU), as the basic unit constituting the DAN network, includes core network capabilities, routing control capabilities, and a resource layer, allowing for rapid interface with local base stations. Furthermore, the capabilities and functions of each layer and aspect of the SCU can be customized, with differences in capabilities between SCUs determined by service requirements.
[0003] Currently, in related technologies, the Network Repository Function (NRF) interaction between SCUs involves service requests and responses via Service Request and Discovery Response functions. However, DAN's plug-and-play nature makes it more vulnerable to malicious attacks. When a user requests a service from an SCU that cannot provide it, the SCU needs to request services from other SCUs. However, the interaction method in related technologies suffers from poor information privacy between SCUs, posing a risk of network attacks, and tends to pursue local optima, leading to poor coordination in network capability borrowing.

[0004] To address the aforementioned technical problems, embodiments of this application provide an information determination method, apparatus, device, computer storage medium, and computer program product, which solve the problems of poor information privacy between SCUs and the risk of being easily attacked in related technologies, while improving the coordination of network capability borrowing.

[0024] The method in the above scheme further includes:

[0056] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.
[0057] This application provides an information determination method, which can be applied to a first NRF network element in a first SCU, referring to... Figure 1 As shown, the method may include the following steps:
[0058] Step 101: Receive the service coordination request sent by the second NRF network element in the second SCU.
[0059] The service coordination request includes the terminal's demand information and the terminal's identifier; the service coordination request is sent by the second NRF network element when it determines that it cannot provide the terminal with the service corresponding to the demand information.
[0060] In this embodiment, the service coordination request is used to instruct the first NRF network element to allocate a target NF network element to the terminal deployed by the second NRF network element; the first NRF network element may refer to a centralized NRF network element, which can be used with NRF 集中 This indicates that the first SCU can refer to a centralized SCU; the second NRF network element can refer to a network element with resource requirements in a distributed NRF network element; and the second SCU can refer to a distributed node SCU.
[0061] Step 102: Obtain the resource information of the network function NF network element to be allocated corresponding to the third NRF network element in the third SCU.
[0062] In the embodiments of this application, NRF 集中 After receiving a service coordination request from the first NRF network element, a network element can obtain resource information of the NF network element to be allocated from its own log information or from the third NRF network element. Specifically, the third NRF network element can refer to a network element in the distributed NRF network element that can provide resources, and the third SCU can refer to a distributed node SCU; the NF network element to be allocated can refer to the NF network element in the third NRF network element.
[0063] Step 103: Based on demand information, resource information, and target decision information, determine the target NF network element from the NF network elements to be allocated, and send the identifier of the target NF network element and the identifier of the terminal to the second NRF network element, so that the second NRF network element can allocate the target NF network element corresponding to the identifier of the target NF network element to provide services to the terminal corresponding to the identifier of the terminal.
[0064] In the embodiments of this application, NRF 集中 Network elements can determine the target NF network element that can provide services to the terminal based on the terminal's own demand information, the resource information of the NF network element to be allocated, and the target decision information; among which, the target decision information can be pre-set decision rules. The target NF network element can refer to the NF network element that ultimately provides services to the terminal, and can be represented by NF. final To express.
[0065] Based on the foregoing embodiments, in other embodiments of this application, step 102 can be implemented in the following manner:
[0066] A1. If the first log information in the first NRF network element is valid, determine the resource information of the NF network element to be allocated from the first log information.
[0067] The first log information can be NRF.集中 Network element's own log information; if NRF 集中 If the network element's own log information is valid, then NRF... 集中 Resource information for NF network elements to be allocated can be obtained from the first log information.
[0068] In other embodiments of this application, step 102 described above can also be implemented in the following ways:
[0069] A2. If the first log information is invalid, obtain the current resource information of the NF network element to be allocated from the third NRF network element.
[0070] Specifically, if NRF 集中 If the network element's own log information is invalid, then NRF... 集中 Obtain the current resource information of the relevant NF network elements from the NRF (i.e., the third NRF) network elements in all subordinate SCUs (i.e., the third SCU) connected to it.
[0071] A3. Update the first log information based on the current resource information, and determine the resource information of the NF network element to be allocated from the updated first log information.
[0072] Among them, NRF 集中 After obtaining the current resource information of the NF network element to be allocated, the network element can update its own log information based on the received current resource information; and, NRF 集中 Network elements can obtain resource information of NF network elements to be allocated from their updated log information.
[0073] In other embodiments of this application, obtaining the current resource information of the NF network element to be allocated from the third NRF network element includes:
[0074] Send an information retrieval request to the third NRF network element;
[0075] Receive current resource information sent by the third NRF network element; wherein the current resource information is obtained by the third NRF network element from the NF network element to be allocated based on the updated second log information.
[0076] Among them, the information retrieval request is NRF 集中 The network element sends information to each third NRF network element to obtain resource information from each third NRF network element; when NRF... 集中 When a network element triggers a network resource acquisition event, the third NRF network element of each third SCU (i.e., distributed SCU) can obtain its own current resource information and feed it back to the NRF. 集中 Network elements. Specifically, such as... Figure 2 NRF shown 集中 Network elements to each NRF 分布Network element initiates a request to acquire network resources; NRF in distributed SCU 分布 Network elements to various NFs 分布 Network elements obtain current resource information, and each NF 分布 Network element to NRF within the domain 分布 Network element feedback of current resource information, NRF 分布 Network element further towards NRF 集中 Network element feedback resource information, NRF 集中 Network element update resource information log file.
[0077] It should be noted that NRF in distributed SCU 分布 Network element subscription domain NF 分布 Network element change information is synchronized to NRF network elements within the domain when a new NF network element or an NF network element becomes disconnected; NRF 分布 Network element update log file, NRF 分布 Network element to NF 分布 Network element feedback log update status.
[0078] In other embodiments of this application, the NRF in the centralized SCU is used as an intermediate node to support interaction, ensuring the information security of each SCU, preventing malicious attacks, and ensuring the overall stable operation of the network. Furthermore, when the distributed SCU cannot provide services to the UE, the decision-making mode for network element selection is modified. The NRF network element of the distributed SCU submits a service borrowing request to the NRF network element in the centralized SCU, along with the user's demand information. Subsequent decisions are made through the NRF network element in the centralized SCU, which is closer to the globally optimal solution.
[0079] In other embodiments of this application, the method may further include the following steps:
[0080] Step 104: Set the service invocation policy information for the target NF network element.
[0081] The service invocation strategy information may include information such as the number of accesses, access time limits, connection stability, latency, and packet loss.
[0082] Step 105: Send service call policy information to the second NRF network element.
[0083] Specifically, when the service call policy information takes effect, the second NRF network element is allowed to directly access the target Internet Protocol (IP) address (i.e., the address of the target NF network element) and borrow the service of the target NF network element when it needs to borrow the same service.
[0084] In the embodiments of this application, such as Figure 3The distributed SCUs shown here access the overall network and perform operations such as registering with the centralized SCUs. The distributed NRF network elements can synchronize their own resource information with the centralized NRF network elements so that the centralized NRF network elements can subsequently find suitable network elements for the source SCUs based on the overall network situation and network policies.
[0085] In other embodiments of this application, such as Figure 4 When a distributed node SCU cannot meet the service requirements of its subordinate user equipment (UE), the distributed SCU requests network element services from the centralized SCU. The centralized SCU, based on the overall network situation and network policies, finds a suitable network element for the source SCU, transmits the address of the network element to the source SCU, and sets the service invocation policy parameters.
[0086] It should be noted that the addition of service invocation policy information enhances the mapping table between the NRF network element's internal storage of demand information and the target NF network element. When a UE's service request is received, if the request cannot be met within the current SCU domain, the mapping table is queried. If the NRF verifies that the service invocation policy information is still valid, the target network element IP address is directly returned to support subsequent operations.
[0087] The information determination method provided in the embodiments of this application allows the second SCU to request network element service borrowing from the first SCU via an NRF network element when the second SCU cannot meet the service needs of its subordinate terminals. The first SCU can combine the overall network resource information and find a suitable target NF network element for the second SCU based on the target decision information. The target NF network element can then provide corresponding services to the terminals, instead of allowing direct interaction between SCUs providing services to each other as in related technologies. This avoids information leakage between them and solves the problem of poor information privacy between SCUs and the risk of being easily attacked in related technologies. At the same time, it considers the overall network resource situation, thereby improving the coordination of network capability borrowing.
[0088] Based on the foregoing embodiments, this application provides an information determination method, which can be applied to a second NRF network element, referring to... Figure 5 As shown, the method may include the following steps:
[0089] Step 201: Receive the first service provision request sent by the terminal.
[0090] The first service provision request includes the terminal's requirement information and the terminal's identifier.
[0091] It should be noted that the first service provision request is the request used by the terminal to obtain services; the terminal's identifier can refer to something that can uniquely identify the terminal, such as the terminal's identity document (ID).
[0092] Step 202: When it is determined that the service corresponding to the required information cannot be provided to the terminal, a service coordination request is sent to the first NRF network element.
[0093] The service coordination request includes demand information and the terminal's identifier.
[0094] Step 203: Receive the identifier of the target NF network element and the identifier of the terminal sent by the first NRF, and assign the target NF network element corresponding to the identifier of the target NF network element to the terminal corresponding to the identifier of the terminal to provide services.
[0095] Specifically, the identifier of the target NF network element can refer to the IP address of the target NF network element; the terminal receives the NRF. 集中 The first network element sends the IP address of the target NF network element and the ID of the terminal. This allows the second NRF network element to be assigned to the terminal with that ID to provide the corresponding service. Simultaneously, the second NRF network element can record the IP address of the target NF network element, forming a mapping table between the demand information and the target NF network element. This way, if there are similar demands later, the IP address of the target NF network element can be directly obtained. The mapping table should at least include information such as the service name, service invocation policy information, and the IP address of the target network element.
[0096] It should be noted that the second NRF network element can provide NRF with... 集中 The network element sends a feedback message confirming receipt of the corresponding information.
[0097] In other embodiments of this application, the method may further include the following steps:
[0098] Step 204: Receive and save the service invocation policy information for the target NF network element sent by the first NRF network element.
[0099] Step 205: After receiving the second service provision request sent by the terminal, and if the service invocation policy is confirmed to be in effect, the target NF network element is allocated to the terminal to provide services.
[0100] Among them, the second service provision request matches the first service provision request.
[0101] Specifically, the second service provision request can be sent to the second NRF network element when the terminal needs the service again; it should be noted that the service obtained by the second service provision request can be the same as the service obtained by the first service provision request.
[0102] In this embodiment of the application, if the second NRF network element determines that the service invocation policy information is effective, it can directly allocate the target NF network element to provide services to the terminal; then, it can directly access the IP address of the target NF network element.
[0103] It should be noted that the descriptions of the same steps and contents as in other embodiments in this embodiment can be found in the descriptions in other embodiments, and will not be repeated here.
[0104] The information determination method provided in the embodiments of this application allows the second SCU to request network element service borrowing from the first SCU via an NRF network element when the second SCU cannot meet the service needs of its subordinate terminals. The first SCU can combine the overall network resource information and find a suitable target NF network element for the second SCU based on the target decision information. The target NF network element can then provide corresponding services to the terminals, instead of allowing direct interaction between SCUs providing services to each other as in related technologies. This avoids information leakage between them and solves the problem of poor information privacy between SCUs and the risk of being easily attacked in related technologies. At the same time, it considers the overall network resource situation, thereby improving the coordination of network capability borrowing.

[0149] The embodiments of this application provide a first NRF network element. When the second SCU cannot meet the service needs of its subordinate terminals, the second SCU requests network element service borrowing from the first SCU through the NRF network element.

The target NF network element can then provide corresponding services to the terminals, instead of allowing direct interaction between SCUs providing services to each other as in related technologies. This avoids information leakage between them and solves the problem of poor information privacy between SCUs and the risk of being easily attacked in related technologies. At the same time, it considers the overall network resource situation, thereby improving the coordination of network capability borrowing.
