Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a contract data management method, device and readable storage medium. Background Art

[0002] An important trend in the development of 6G networks is centralized and distributed network architecture. The initial design of 5G and previous generations of network architecture is centralized control. 6G will be oriented towards diversified scenarios and network requirements in the air, sky, land, and sea. The centralized network architecture cannot uniformly meet all scenarios. Therefore, with the development of the network, facing the dual driving forces of business scenarios and technological development, the 6G network architecture needs to go beyond centralized control and gradually evolve to a distributed architecture, extending more networks to the edge of the network, and establishing distributed network nodes with different functions. Multiple distributed network nodes can form autonomous micro-networks according to business needs, and provide targeted network services according to specific business scenarios, user scale, geographical environment and other requirements. Among them, the above-mentioned distributed network nodes represent an on-demand customized or fully functional core network.

[0003] For the 6G distributed network architecture, the user's subscription data may not exist in all distributed network nodes due to the redundant storage overhead of distributed data. At present, the existing solution is to obtain the subscription data from the corresponding network node based on demand or by spreading it to other network nodes with node relationships. However, this method may result in some network nodes not serving the UE again or the UE only staying briefly in some distributed network nodes. If the UE's subscription data in this scenario cannot be effectively managed, it will take up more storage space, resulting in a waste of resources.

[0004] Therefore, in the prior art, it is impossible to effectively manage contract data under a distributed network architecture, which leads to a waste of resources. Summary of the invention

[0235] The term "and / or" in this application describes the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0236] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0237] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0238] In order to clearly understand the technical solution of the present application, the solution of the prior art is first introduced in detail. An important trend in the development of 6G networks is centralized and distributed network architecture. The initial design of the network architecture of 5G and previous generations is centralized control. 6G will be oriented towards diversified scenarios and network requirements in the air, sky, land, and sea. The centralized network architecture cannot uniformly meet all scenarios. Therefore, with the development of the network, facing the dual driving forces of business scenarios and technological development, the 6G network architecture needs to go beyond centralized control and gradually evolve to a distributed architecture, extending more networks to the edge of the network, and establishing distributed network nodes with different functions. Multiple distributed network nodes can form autonomous micro-networks according to business needs, and provide targeted network services according to specific business scenarios, user scale, geographical environment and other requirements. Among them, the above-mentioned distributed network nodes represent an on-demand customized or fully functional core network.

[0239] For the 6G distributed network architecture, the user's subscription data may not exist in all distributed network nodes due to the redundant storage overhead of distributed data. At present, the existing solution is to obtain the subscription data from the corresponding network node based on demand or by spreading it to other network nodes with node relationships. However, this method may result in some network nodes not serving the UE again or the UE only staying briefly in some distributed network nodes. If the UE's subscription data in this scenario cannot be effectively managed, it will take up more storage space, resulting in a waste of resources.

[0240] Therefore, in the prior art, it is impossible to effectively manage contract data under a distributed network architecture, which leads to a waste of resources.

[0241] The inventors further discovered that in order to solve the problem in the prior art that contract data cannot be effectively managed under a distributed network architecture, thereby causing waste of resources, statistical intelligent analysis can be performed based on the UE's business needs, the UE's current location, the UE's location change trend, the UE's status, the UE's historical movement trajectory, etc., and the relevant information of other network nodes, such as network status, load, capacity, etc., can be combined to predict the network node that the UE will serve next, and then push the UE's contract data to the network node that will serve the UE next or push the UE's contract data to a designated distributed network node (including a centralized node that governs the network nodes serving the UE, or a distributed network node); or, based on the UE's location change trend, the currently accessed business and other information, an intelligent judgment can be made as to whether the UE's contract data should be obtained. If necessary, the UE's contract data can be actively obtained from the centralized node / other distributed network nodes, which can effectively manage the contract data and save resources.

[0242] Therefore, based on the creative research of the above inventors, the contract data management method and device proposed in this application are proposed. In this application, intelligent analysis is performed based on the business needs of the UE, the current location of the UE, the status of the UE, the historical movement trajectory of the UE, etc., and the relevant information of other network nodes, such as network status, load, capacity, etc., can also be combined to predict the network node (i.e., the target network node) that the UE will serve next, and then send a message carrying the contract data of the UE (including direct or indirect methods) to the target network node to select a better network node for the UE, or the target network node actively obtains the contract data from the initial network node or the network node with the ability to manage the target network node. Effective management of contract data is achieved, rather than randomly sending contract data to one or some network nodes or sending contract data to one or more network nodes with a shorter service time. Therefore, the problem of occupying more storage space and causing resource waste caused by the prior art is solved, and network resources are saved.

[0243] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0244] Embodiments of the present application will be described below with reference to the accompanying drawings.

[0245] It should be noted that this application is discussed based on the assumption that a distributed network architecture includes multiple central network nodes (herein, centralized network nodes or centralized nodes) and multiple distributed network nodes, as well as multiple distributed network representatives, and these networks all belong to the same operator. Figure 1 To illustrate schematically, Figure 1 A schematic diagram of a scenario of the relationship between network nodes based on a distributed network architecture provided for an embodiment of the present application. Among them, the central network node has complete and powerful network functions, has global data information within its jurisdiction, and supports collaboration between distributed network nodes; the distributed network node has basic control plane functions and user plane functions, can exist independently to provide connection services to users, and other network functions can be optionally deployed. It has data information and control authority of this node, and can optionally have data information and control authority of some other network nodes; in addition, some distributed network nodes have more resources and powerful processing capabilities, such as memory, storage and other resources, and may act as a similar centralized node role within a small range (smaller than the service range of a centralized node), which is referred to as a distributed network node representative in this application, such as Figure 1 The distributed network node 22 can act as a distributed network node representative. In this application, the centralized node and the distributed network node representative are regarded as network nodes capable of managing the target network node, which will not be described in detail below.

Among them, based on the signing data addition / update stage, the implementation method includes: method A, distributed network node A / centralized node 1 (here refers to the initial network node) determines that distributed network node B (here refers to the target network node) is the network node that will serve the UE through intelligent judgment and decision-making, and sends the signing data notification (message) to the distributed network node B (the signing data notification message may carry a timer (here refers to the configuration information of the timer, such as: timing indication information, the timing indication information includes the storage duration of the signing data of each of the UEs, and for each of the UEs, the timing indication information is used to indicate that when the storage duration is exceeded, the signing data of the UE is processed by any of the following items: deleting the signing data of the UE; marking the signing data of the UE as expired; marking the freshness of the signing data as low)), the distributed network node B sends the signing data notification response (message) to the distributed network node A / centralized node 1 (the signing data notification response message may carry a signing data subscription); wherein, the distributed network node B can configure / update the signing data.

[0249] Method B, distributed network node A / centralized node 1 (here refers to the initial network node) sends a contract data notification (message) to distributed network node C / centralized node 2 (here refers to the network node with the ability to manage the target network node) (the contract data notification message may carry a timer (the configuration information of the message timer is specified here)), and distributed network node C / centralized node 2 sends a contract data notification response (message) to distributed network node A / centralized node 1 (the contract data notification response message may carry a contract data subscription), wherein distributed network node C / centralized node 2 may configure / update the contract data; when distributed network node D (here refers to the target network node) needs to obtain a contract data trigger, it sends a contract data acquisition request (message) to distributed network node C / centralized node 2 (which may carry a contract data subscription), and distributed network node C / centralized node 2 sends a contract data acquisition response (message) to distributed network node D.

[0250] Method C includes method C1 and method C2; wherein, in method C1, distributed network node A / centralized node 1 (here refers to the initial network node) sends a UE event notification (message) to distributed network node B (here refers to the target network node), distributed network node B sends a contract data acquisition request (message) (which may include contract data subscription) to distributed network node A / centralized node 1, and distributed network node A / centralized node 1 sends a contract data acquisition response (message) to distributed network node B (which may carry a timer). Method C2, distributed network node A / centralized node 1 (here refers to the initial network node) sends a UE event notification (message) to distributed network node C / centralized node 2 (here refers to the network node with the ability to manage the target network node), distributed network node C / centralized node 2 sends a contract data acquisition request (message) (which may include a contract data subscription) to distributed network node A / centralized node 1, and distributed network node A / centralized node 1 sends a contract data acquisition response (message) (which may carry a timer) to distributed network node C / centralized node 2; when distributed network node D (here refers to the target network node) needs to obtain a contract data trigger, it sends a contract data acquisition request (message) (which may carry a contract data subscription) to distributed network node C / centralized node 2, and distributed network node C / centralized node 2 sends a contract data acquisition response (message) to distributed network node D.

[0251] Among them, for the above-mentioned processing methods A, B, and C, based on the subscription data processing stage (including deletion, marking, etc.), the implementation methods include: Method A, if the target message contains timing indication information, then the distributed network node B, the distributed network node A / centralized node 1, and the distributed network node C / centralized node 2 all process the subscription data, for example, delete the subscription data of the UE; mark the subscription data of the UE as expired; mark the subscription data as having low freshness, etc. Method B, if the target message does not contain timing indication information, the distributed network node B or the distributed network node C / centralized node 2 intelligently determines whether the subscription data needs to be deleted, and if necessary, performs the deletion operation, and sends a subscription data unsubscription (message) to the distributed network node A / centralized node 1 (here refers to a message used to indicate the cancellation of subscription to subscription data), and then the distributed network node A / centralized node 1 sends a subscription data unsubscription response (message) to the distributed network node B or the distributed network node C / centralized node 2 (here refers to a response message used to indicate the cancellation of subscription to subscription data).

[0252] Processing method 2: Request mode contract data acquisition processing method.

[0253] Combination Figure 3 As shown, Figure 3This is an interactive diagram of a contract data management method provided by another embodiment of the present application, such as Figure 3 As shown, the interactive scenario includes distributed network node B, distributed network node A / centralized node 1, distributed network node C / centralized node 2 and distributed network node D. Among them, based on the subscription data addition / update stage, the implementation method includes: method A1, distributed network node B (here refers to the target network node) determines whether it is necessary to obtain the subscription data of the UE through intelligent judgment and decision-making, and if it is necessary to obtain, it sends a subscription data acquisition request (message) (which may include subscription data subscription, timer) to distributed network node A / centralized node 1 (here refers to the initial network node), and distributed network node A / centralized node 1 sends a subscription data acquisition response (message) to distributed network node B; wherein, distributed network node B can configure / update the subscription data.

[0254] Mode A2, distributed network node C / centralized node 2 (here refers to the network node with the ability to manage the target network node) determines whether it is necessary to obtain the UE's contract data through intelligent judgment and decision-making. If it is necessary to obtain, it sends a contract data acquisition request (message) (which may include contract data subscription, timer) to the distributed network node A / centralized node 1 (here refers to the initial network node), and the distributed network node A / centralized node 1 sends a contract data acquisition response (message) to the distributed network node C / centralized node 2; wherein, the distributed network node C / centralized node 2 can configure / update the contract data; when the distributed network node D (here refers to the target network node) needs to obtain the contract data trigger, it sends a contract data acquisition request (message) to the distributed network node C / centralized node 2 (which may carry the contract data subscription), and the distributed network node C / centralized node 2 sends a contract data acquisition response (message) to the distributed network node D.

[0255] Among them, for the above-mentioned processing methods A1 and A2, based on the subscription data processing stage (including deletion, marking and other processing), the implementation methods include: Method A, if the target message contains timing indication information, then the distributed network node B, the distributed network node A / centralized node 1, and the distributed network node C / centralized node 2 all process the subscription data, for example, delete the subscription data of the UE; mark the subscription data of the UE as expired; mark the subscription data as having low freshness, etc. Method B, if the target message does not contain timing indication information, the distributed network node B or the distributed network node C / centralized node 2 intelligently determines whether the subscription data needs to be deleted, and if necessary, performs the deletion operation, and sends a subscription data unsubscription (message) to the distributed network node A / centralized node 1 (here refers to a message used to indicate the cancellation of subscription to subscription data), and then the distributed network node A / centralized node 1 sends a subscription data unsubscription response (message) to the distributed network node B or the distributed network node C / centralized node 2 (here refers to a response message used to indicate the cancellation of subscription to subscription data).

[0256] Therefore, the distributed network node or centralized network node storing the subscription data of the UE can perform intelligent analysis based on the UE business needs, the current location of the UE, the trend of the location change of the UE, the service status of the UE, the historical movement trajectory of the UE, etc., and can also combine the relevant information of other network nodes, such as status, load, capacity and other information, to predict the network node (i.e., the target network node) that the UE will serve next, and then send the message carrying the subscription data of the UE (including direct or indirect methods) to the target network node to select a better network node for the UE; or, the target network node actively obtains the subscription data from the initial network node or the network node with the ability to manage the target network node. Effective management of subscription data is achieved, rather than randomly sending subscription data to one or some network nodes or sending subscription data to one or more network nodes with a shorter service time. Therefore, the problem of occupying more storage space and causing resource waste caused by the prior art is solved, and network resources are saved.

[0257] At the same time, there is no need for frequent interactions. When the UE's contract data needs to be obtained, the UE's contract data can be obtained and saved for subsequent process processing directly between the initial network node and the target network node or through interaction between network nodes with the ability to manage the target network node. In this way, there is no need to frequently obtain the UE contract data from the centralized node / other distributed network nodes to save signaling overhead and reduce latency, thereby realizing intelligent management of contract data. This solves the problem of high signaling interaction latency when a 5GS-like roaming scenario is used, where the user's contract data is located in distributed node 1 and the user accesses from distributed network node 2, and multiple interactions between NFs in distributed network node 2 and NFs in distributed network node 1 are required.

[0258] Figure 4 A flowchart of the contract data management method provided in the embodiment of the present application is shown in FIG. Figure 1 As shown, the execution subject of the subscription data management method provided in this embodiment is an initial network node storing the subscription data of the user terminal UE under a distributed network architecture, and the initial network node is a distributed network node or a centralized network node; the subscription data management method provided in the embodiment of the present application includes the following steps:

[0259] Step 101: Determine a target network node to be provided with a service for the UE from among the other network nodes according to the relevant information of the UE and the relevant information of other network nodes except the network node storing the subscription data of the UE.

[0260] Among them, the relevant information of the UE includes at least one of the following: the business needs of the UE, the current location of the UE, the status of the UE and the historical movement trajectory of the UE; the relevant information of other network nodes includes at least one of the following: load information, capability information and network status information of each network node in the other network nodes.

[0261] The historical movement trajectory here may include the number of visits within a period of time, the length of each stay, etc. The capability information here may include: computing power orchestration capability, AI capability, data service capability, etc.; network status information, such as available or unavailable status, etc. UE status, such as idle state, connected state, etc.

[0262] In an embodiment of the present application, the initial network node can perform intelligent analysis based on the UE's business needs, the UE's current location, the UE's status, the UE's historical movement trajectory, etc., and can also combine relevant information of other network nodes, such as network status, load, capacity and other information, to predict the network node (i.e., the target network node) that the UE will serve next.

[0263] Step 102: Send a target message to the target network node, wherein the target message includes the subscription data of the UE.

[0264] Specifically, the initial network node sends a message carrying the UE's subscription data (including direct or indirect methods) to the target network node, selects a better network node for the UE, and effectively manages the subscription data, instead of randomly sending the subscription data to one or some network nodes or sending the subscription data to one or more network nodes with a shorter service time. Therefore, the problem of occupying more storage space and causing waste of resources brought about by the prior art is solved, and network resources are saved.

[0265] In the embodiment of the present application, first, according to the relevant information of the UE and the relevant information of other network nodes except the network node storing the subscription data of the UE, the target network node to be provided with service for the UE is determined from the other network nodes, and then the target message is sent to the target network node. That is, based on the service needs of the UE, the current location of the UE, the status of the UE, the historical movement trajectory of the UE, etc., intelligent analysis is performed, and the relevant information of other network nodes, such as network status, load, capacity, etc., can also be combined to predict the network node (i.e., the target network node) to be served by the UE next, and then the message carrying the subscription data of the UE (including direct or indirect methods) is sent to the target network node, and a better network node is selected for the UE, so as to effectively manage the subscription data, instead of randomly sending the subscription data to one or some network nodes or sending the subscription data to one or more network nodes with a shorter service time. Therefore, the problem of occupying more storage space and causing resource waste caused by the prior art is solved, and network resources are saved.

[0266] Optionally, the determining, according to the relevant information of the UE and relevant information of other network nodes except the network node storing the subscription data of the UE, a target network node to be provided service for the UE from the other network nodes includes:

[0267] According to the service demand of the UE, the current location of the UE, the load information, capability information and network status information of each of the other network nodes, the location change trend of the UE is predicted by a pre-trained prediction model;

[0268] According to the position change trend of the UE, the state of the UE and the historical movement trajectory of the UE, the probability of each network node in the other network nodes being the target network node is determined by the prediction model;

[0269] The target network node is determined from the other network nodes according to the probability corresponding to each network node in the other network nodes and the service demand of the UE.

[0270] In the embodiment of the present application, the initial network node determines the network node that is about to serve the UE preferably through intelligent analysis. Common AI algorithms can be used, such as reinforcement learning algorithms based on graph neural networks, etc., and the distributed network node load information, capability information, and network status information, etc., combined with the user's business needs, the user's current location and other parameters are input into the graph neural network to obtain the user's location change trend; then the user's location change trend, the user's status, and the user's historical trajectory are input into the graph neural network to obtain the probability of accessing the current distributed network node; finally, a distributed network node for a service, i.e., the target network node, is determined based on the probability, the user's business needs and other parameters; wherein, the deployment of the AI ​​algorithm can be an independent network element or an existing network element inside the distributed node (here refers to the initial network node). Therefore, the accuracy of the results predicted by intelligent analysis is relatively high.

[0271] Specifically, the target network node may be determined in at least two of the following implementation methods:

[0272] Method 1: There is only one trained prediction model, which includes at least two network layers. The first network layer inputs the UE's business needs, the UE's current location, the load information, capability information and status information of each of the other network nodes, and the output is the UE's location change trend. The second network layer inputs the UE's location change trend, the UE's service status and the UE's historical movement trajectory, and the output is the probability that each of the other network nodes will serve the user.

[0273] Method 2: The prediction model includes a first prediction model and a second prediction model, the input and output of the first prediction model are similar to the first network layer, and the input and output of the second prediction model are similar to the second network layer. No further details will be given here.

[0274] Optionally, the sending a target message to the target network node includes any of the following:

[0275] directly sending a subscription data notification message to the target network node, using the subscription data notification message as the target message;

[0276] sending a UE event notification message to the target network node, where the UE event notification message is used to indicate that the target network node is about to serve the UE; if a subscription data acquisition request message sent by the target network node is received, sending a subscription data acquisition response message to the target network node, and using the subscription data acquisition response message as the target message;

[0277] Sending a target message to the target network node through a network node with the ability to manage the target network node among the other network nodes; the management scope of the network node with the ability to manage the target network node includes the current location of the UE, and the network node with the ability to manage the target network node is used to support sending the target message to the target network node when the target network node needs to obtain the subscription data of the UE;

[0278] The target network node is used to save the subscription data of the UE in the target message after receiving the target message.

[0279] In an embodiment of the present application, the initial network node may send a target message to the target network node by directly sending a subscription data notification message to the target network node as the target message, which at least includes the subscription data of the UE; the initial network node may also send a UE event notification message to the target network node to indicate that the target network node is about to serve the UE, and when the target network node needs to obtain the subscription data of the UE, it sends a subscription data acquisition request message to the initial network node. When the initial network node receives the subscription data acquisition request message sent by the target network node, it sends a subscription data acquisition response message to the target network node as the target message, which at least includes the subscription data of the UE; the initial network node may also send a target message to the target network node through a network node among other network nodes that has the ability to manage the target network node, and when it is determined that the target network node needs to obtain the subscription data of the UE, it sends a target message to the target network node, which at least includes the subscription data of the UE.

[0280] Therefore, the initial network node can send the target message to the target network node in a variety of ways, achieving flexibility and diversity.

[0281] Optionally, sending the target message to the target network node through the network node having the ability to manage the target network node among the other network nodes includes:

[0282] Sending the subscription data notification message to the network node capable of managing the target network node;

[0283] Among them, the network node capable of managing the target network node is used to save at least the subscription data of the UE in the subscription data notification message after receiving the subscription data notification message; the network node capable of managing the target network node is also used to send a subscription data acquisition response message to the target network node based on the saved subscription data of the UE when receiving a subscription data acquisition request message sent by the target network node, and use the subscription data acquisition response message as the target message.

[0284] In an embodiment of the present application, the initial network node first sends a contract data notification message to a network node capable of managing the target network node. After receiving the contract data notification message, the network node capable of managing the target network node at least saves the contract data of the UE in the contract data notification message. When the target network node needs to obtain the contract data of the UE, it sends a contract data acquisition request message to the network node capable of managing the target network node. When the network node capable of managing the target network node receives the contract data acquisition request message sent by the target network node, it sends a contract data acquisition response message to the target network node as a target message based on the saved contract data of the UE.

[0285] Optionally, sending the target message to the target network node through the network node having the ability to manage the target network node among the other network nodes includes:

[0286] Sending a UE event notification message to the network node capable of managing the target network node;

[0287] If a subscription data acquisition request message sent by the network node capable of managing the target network node is received, sending a subscription data acquisition response message to the network node capable of managing the target network node;

[0288] Among them, the network node capable of managing the target network node is also used to send a subscription data acquisition response message to the target network node when receiving a subscription data acquisition request message sent by the target network node, and use the subscription data acquisition response message as the target message.

[0289] In an embodiment of the present application, the initial network node sends a UE event notification message to a network node capable of managing the target network node. After receiving the UE event notification message, the network node capable of managing the target network node may send a subscription data acquisition request message to the initial network node if it needs to obtain the subscription data of the UE. When the initial network node receives the subscription data acquisition request message sent by the network node capable of managing the target network node, the initial network node sends a subscription data acquisition response message to the network node capable of managing the target network node. The network node capable of managing the target network node may save the subscription data acquisition response message, which at least includes the subscription data of the UE. When the target network node needs to obtain the subscription data of the UE, it may send a subscription data acquisition request message to the network node capable of managing the target network node. When the network node capable of managing the target network node receives the subscription data acquisition request message sent by the target network node, the network node capable of managing the target network node sends a subscription data acquisition response message to the target network node as a target message based on the saved subscription data acquisition response message, which at least includes the subscription data of the UE.

[0290] Specifically, the target network node may receive the target message sent by the initial network node in at least the following four ways:

[0291] Mode 11: The target network node directly receives the target message sent by the initial network node.

[0292] Mode 12: The target network node first receives the UE event notification message sent by the initial network node, determines that its own network node is about to serve the UE, sends a subscription data acquisition request message to the initial network node, and then receives the target message sent by the initial network node.

[0293] Method 13: The target network node first sends a contract data acquisition request message to a network node that has the capability to manage the target network node. When the network node that has the capability to manage the target network node receives the contract data acquisition request message sent by the target network node, the network node that has the capability to manage the target network node sends a contract data acquisition response message as the target message based on the contract data of the UE in the contract data notification message sent by the initial network node to the network node that has the capability to manage the target network node. The target network node receives the target message sent by the network node that has the capability to manage the target network node.

[0294] Method 14: The target network node first sends a subscription data acquisition request message to the network node with the ability to manage the target network node, and then receives a subscription data acquisition response message sent by the network node with the ability to manage the target network node, and uses the subscription data acquisition response message as the target message, that is: receiving the target message sent by the network node with the ability to manage the target network node; wherein, the initial network node first sends a UE event notification message to the network node with the ability to manage the target network node, and after receiving the UE event notification message, the network node with the ability to manage the target network node sends a subscription data acquisition request message to the initial network node, and the initial network node is used to send a subscription data acquisition response message to the network node with the ability to manage the target network node when receiving the subscription data acquisition request message sent by the network node with the ability to manage the target network node, wherein the network node with the ability to manage the target network node saves the subscription data in the acquisition request response message to support subsequent sending to the target network node.

[0295] Optionally, after directly sending the subscription data notification message to the target network node, the method further includes:

[0296] A subscription data notification response message sent by the target network node is received. If the target network node needs to subscribe to update events of the subscription data, the subscription data notification response message includes a subscription message for indicating a privacy subscription to update events of the subscription data.

[0297] In the embodiment of the present application, after the initial network node directly sends a subscription data notification message to the target network node, if the target network node needs to subscribe to an update event of the subscription data, when the target network node receives the subscription data notification message, it sends a subscription data notification response message carrying a subscription message for indicating an update event of the privacy subscription subscription data to the initial network node, so as to obtain the subscription data of the UE in real time.

[0298] Optionally, the method further comprises:

[0299] If the target network node needs to subscribe to an update event of the subscription data, the received subscription data acquisition request message sent by the target network node includes a subscription message for indicating a privacy subscription to the update event of the subscription data;

[0300] The subscription message is used to obtain real-time contract data.

[0301] In the embodiment of the present application, if the target network node needs to subscribe to the update event of the subscription data, when the target network node sends a subscription data acquisition request message to the initial network node, the subscription data acquisition request message includes a subscription message for indicating the update event of the privacy subscription subscription data. Therefore, the subscription data acquisition request message sent by the target network node and received by the initial network node carries the subscription message. The subscription data of the UE is acquired in real time.

[0302] Optionally, after sending the subscription data notification message to the network node having the capability of managing the target network node, the method further includes:

[0303] receiving a subscription data notification response message sent by the network node capable of managing the target network node, wherein if the network node capable of managing the target network node needs to subscribe to an update event of the subscription data, the subscription data notification response message includes a subscription message for indicating a privacy subscription to the update event of the subscription data;

[0304] The subscription message is used to obtain real-time contract data.

[0305] In the embodiment of the present application, after the initial network node sends the subscription data notification message to the network node capable of managing the target network node, if the network node capable of managing the target network node needs to subscribe to the update event of the subscription data, the network node capable of managing the target network node sends a subscription data notification response message to the initial network node, which carries a subscription message for indicating the update event of the privacy subscription subscription data, and the subscription data notification response message sent by the network node capable of managing the target network node received by the initial network node includes the subscription message. Real-time acquisition of the UE's subscription data is achieved.

[0306] Optionally, the method further comprises:

[0307] If the network node capable of managing the target network node needs to subscribe to an update event of the subscription data, the received subscription data acquisition request message sent by the network node capable of managing the target network node includes a subscription message for indicating a privacy subscription to an update event of the subscription data;

[0308] The subscription message is used to obtain real-time contract data.

[0309] In the embodiment of the present application, if the network node capable of managing the target network node needs to subscribe to the update event of the subscription data, when the network node capable of managing the target network node sends a subscription data acquisition request message to the initial network node, the subscription data acquisition request message carries a subscription message for indicating the update event of the privacy subscription subscription data, so the subscription data acquisition request message sent by the network node capable of managing the target network node received by the initial network node includes the subscription message. Real-time acquisition of the UE's subscription data is achieved.

[0310] Specifically, corresponding to the above-mentioned method 11, after the target network node directly receives the contract data notification message sent by the initial network node, if the target network node needs to subscribe to the update event of the contract data, the target network node sends a contract data notification response message to the initial network node, and the contract data notification response message carries a subscription message for indicating the update event of the privacy subscription contract data, to obtain real-time contract data.

[0311] Corresponding to the above-mentioned method 12, after the target network node sends a contract data acquisition request to the initial network node, if the target network node needs to subscribe to update events of the contract data, the contract data acquisition request message sent by the target network node to the initial network node carries a subscription message for indicating a privacy subscription to update events of the contract data, to obtain real-time contract data.

[0312] Corresponding to the above-mentioned method 13, if the network node with the ability to manage the target network node needs to subscribe to the update event of the contract data, the contract data notification response message sent by the network node with the ability to manage the target network node to the initial network node includes a subscription message for indicating the update event of the privacy subscription contract data, so as to obtain real-time contract data.

[0313] Corresponding to the above-mentioned method 4, if the network node capable of managing the target network node needs to subscribe to the update event of the subscription data, the subscription data acquisition request message sent by the network node capable of managing the target network node to the initial network node carries a subscription message for indicating the update event of the privacy subscription subscription data, so as to obtain the real-time subscription data. Therefore, by obtaining the real-time subscription data, better services can be provided to the UE in a timely and effective manner.

[0314] Optionally, there is at least one UE, and the target message also includes at least one of the following: an identifier of each UE and timing indication information for performing timed processing of the subscription data of each UE, the timing indication information including the storage duration of the subscription data of each UE, and for each UE, the timing indication information is used to indicate that when the storage duration is exceeded, the subscription data of the UE is processed by any one of the following:

[0315] Deleting subscription data of the UE;

[0316] Marking that the subscription data of the UE has expired;

[0317] The freshness of the marked contract data is low;

[0318] The storage duration is determined based on at least one of the historical movement trajectory of the UE and the type of service currently accessed.

[0319] The storage duration here is obtained based on at least one of the historical movement trajectory of the UE and the currently accessed service type, and is obtained through a model trained by an AI algorithm, etc. The AI ​​algorithm is not specifically limited here.

[0320] In an embodiment of the present application, if it is necessary to delete the contract data or perform other processing operations on the contract data, the configured timing indication information can be carried in the target message, and the contract data of the UE can be processed accordingly through the timing indication information. For example, when the storage period is exceeded, the initial network node, the target network node, and the network node capable of managing the target network node that store the contract data all delete the contract data of the UE, mark the contract data of the UE as expired, and mark the contract data as having a low freshness, etc.; wherein, the storage period can also be determined by an AI algorithm based on the UE's historical movement trajectory and / or the currently accessed service type.

[0321] Optionally, the method further comprises:

[0322] If the target message does not include the timing indication information, determining, by the target network node or the network node capable of managing the target network node, whether it is necessary to delete the subscription data of the UE based on at least one of a historical movement trajectory of the UE and a currently accessed service type;

[0323] The target network node or the network node capable of managing the target network node is used to perform a deletion operation of the subscription data of the UE when it is determined to delete the subscription data of the UE.

[0324] In an embodiment of the present application, whether the subscription data of the UE needs to be deleted can be determined directly through the target network node or a network node capable of managing the target network node based on the historical movement trajectory of the UE and / or the type of service currently accessed.

[0325] Therefore, configurability and flexibility in contract data processing are achieved, and expired contract data is deleted to save occupied resources. Contract data is marked as expired or less fresh to provide a basis for subsequent processing of contract data.

[0326] Optionally, the method further comprises:

[0327] receiving a subscription data acquisition request message sent by the target network node; the subscription data acquisition request message is triggered when the target network node determines that the subscription data of the UE needs to be acquired based on the relevant information of the UE and the relevant information of the target network node; the relevant information of the target network node includes at least one of the following: load information, capability information and network status information of the target network node;

[0328] Send a subscription data acquisition response message to the target network node, and use the subscription data acquisition response message as the target message.

[0329] In the embodiment of the present application, the initial network node directly receives the subscription data acquisition request message sent by the target network node, and sends the target message to the target network node, wherein the target network node sends the subscription data acquisition request message to the initial network node when determining that the subscription data of the UE needs to be acquired based on the relevant information of the UE and the load information, capability information and network status information of the target network node, etc. The subscription data acquisition processing in the active request mode of the target network node is realized.

[0330] Optionally, the method further comprises:

[0331] receiving a subscription data acquisition request message sent by a network node having the capability of managing the target network node among the other network nodes; the subscription data acquisition request message is triggered when the network node having the capability of managing the target network node determines that the subscription data of the UE needs to be acquired based on the relevant information of the UE and the relevant information of the target network node; the relevant information of the target network node includes at least one of the following: load information, capability information, and network status information of the target network node;

[0332] Sending a subscription data acquisition response message to the network node capable of managing the target network node;

[0333] The network node having the ability to manage the target network node is used to support sending a subscription data acquisition response message to the target network node when receiving a subscription data acquisition request message sent by the target network node; the subscription data acquisition request message sent by the target network node to the network node having the ability to manage the target network node is triggered when it is determined that the target network node needs to obtain the subscription data of the UE;

[0334] The signing data acquisition response message is used as the target message.

[0335] In an embodiment of the present application, an initial network node receives a subscription data acquisition request message sent by a network node with the capability to manage the target network node, and sends a target message to the network node with the capability to manage the target network node, wherein the network node with the capability to manage the target network node sends the subscription data acquisition request message to the initial network node when determining that the subscription data of the UE needs to be acquired based on relevant information of the UE and the load information, capability information, and network status information of the target network node, and when determining that the target network node needs to acquire the subscription data of the UE, the target network node sends the subscription data acquisition request message to the network node with the capability to manage the target network node, and when the network node with the capability to manage the target network node receives the subscription data acquisition request message sent by the target network node, it sends the target message to the target network node, thereby realizing the subscription data acquisition processing of the target network node in an active request mode through the network node with the capability to manage the target network node.

[0336] The following describes the contract data management method in detail through at least two processing methods.

[0337] Processing method 1, push mode contract data acquisition processing method, is described in detail through at least four embodiments below.

[0338] Exemplary embodiment 1 (the subscription data is stored in the distributed network node to provide services, that is, the target network node; this embodiment includes a distributed network node B (herein, the target network node), a distributed network node A / centralized node (1) (herein, the initial network node); the UE here is at least one.)

[0339] See also Figure 5 As shown, Figure 5 A signaling flow diagram of a subscription data management method provided in another embodiment of the present application. The subscription data management method provided in this embodiment includes the following steps:

[0340] The whole process is divided into the adding / updating phase and the deleting phase. First, the adding process is performed:

[0341] Step 1. Distributed network node A / centralized node makes intelligent judgment and decision.

[0342] Distributed network node A / centralized node performs statistical analysis based on UE business needs, UE current location, UE location change trend, UE service status, UE historical movement trajectory, etc., and can also combine relevant information of other network nodes, such as (network) status, load, capacity and other information, to perform intelligent analysis to predict the network node that the UE will serve next, that is, distributed network node B. Among them, intelligent analysis can use commonly used AI algorithms, such as reinforcement learning algorithms based on graph neural networks, and input information such as distributed network node load, capacity, network status, and user (UE) business needs, user current location and other parameters into the graph neural network to obtain the user's location change trend; then input the user's location change trend, user status, and historical trajectory to obtain the probability of accessing the current distributed network node; finally, determine a distributed network node for service based on parameters such as probability and business needs; the deployment of the AI ​​algorithm can be an independent network element or an existing network element inside the distributed node.

[0343] Step 2. Distributed network node A / centralized node sends a subscription data notification (message) to distributed network node B.

[0344] Based on the result of the prediction in step 1, the distributed node A / centralized node pushes the subscription data of the UE to the network node that will serve the UE next, that is, the distributed node B. The information carried includes the UE identification (list), the UE's subscription data, and may also include a timer (the usage duration of the subscription data. When the timer times out, the subscription data of the UE is released; here, the timing indication information is specified, and the timing indication information includes the storage duration of the subscription data of each UE, and for each UE, the timing indication information is used to indicate that when the storage duration is exceeded, the subscription data of the UE is processed by any of the following items: deleting the UE's subscription data; marking the UE's subscription data as expired; marking the subscription data as having a low freshness). The determination of the timer value (here including the storage duration or usage duration) is obtained based on the intelligent analysis of the above-mentioned statistical information. The determination of the timer can also be based on information such as the number of visits, duration of stay, and services (type of services currently accessible) of the UE in the current area (which may also include other areas); the retention time of the contract data can be intelligently determined; the intelligent analysis can adopt commonly used AI algorithms, such as reinforcement learning algorithms based on graph neural networks, and input information such as distributed network node load, capacity, network status, and parameters such as the user's business needs and the user's current location into the graph neural network to obtain the user's location change trend and historical movement trajectory (including the number of visits within a period of time, i.e., the number of visits, and the length of each stay, i.e., the length of stay); then the user's location change trend and historical movement trajectory (including the number of visits within a period of time, i.e., the length of each stay) are input to obtain the range and corresponding probability of the long retention time of the contract data; finally, a suitable timer value is determined based on parameters such as probability and business needs.

[0345] Step 3. Distributed network node B sends a subscription data notification response (message) to distributed network node A / centralized node.

[0346] After receiving the contract data, the distributed network node B saves it and then sends a response message.

[0347] Step 4. Distributed network node B configures / updates subscription data.

[0348] If it is necessary to subscribe to the update event of the contract data, a private subscription message (here, a subscription message used to indicate the update event of the private subscription contract data) is carried in the response message to obtain real-time contract data.

[0349] Then if an update is needed, repeat steps 2-4.

[0350] Finally, if the contract data needs to be deleted, the processing is performed:

[0351] If a timer is carried in step 2, step 5 is executed: when the timer times out, the distributed network node A / centralized node and the distributed network node B all execute the contract data deletion or mark the contract data as expired or mark the freshness of the contract data (the lower the freshness, the worse the real-time performance of the data).

[0352] If no timer is carried in step 2, the distributed network node B intelligently determines whether the UE's contract data needs to be deleted based on historical information (including historical movement trajectories consisting of number of visits, length of stay, etc.), the currently visited service type, and other information. If the contract data needs to be deleted, execute steps 6-8; otherwise, continue to save the UE's contract data.

[0353] Step 6. Distributed network node B deletes the contract data based on the intelligent judgment result.

[0354] Step 7. Distributed network node B sends a subscription data unsubscription message to distributed network node A / centralized node (meaning no longer subscribe, here refers to the message used to indicate the cancellation of subscription data).

[0355] Step 8. The distributed network node A / centralized node receives the request message (here refers to the contract data unsubscribe message), performs corresponding operations (such as unsubscribe), and then sends a response message (here refers to the contract data unsubscribe response message).

[0356] Exemplary embodiment 2 (the contract data is stored in the distributed network node to provide services, that is, the target network node; this embodiment includes the distributed network node B (here refers to the target network node), the distributed network node A / centralized node (here refers to the initial network node))

[0357] See also Figure 6 As shown, Figure 6 This is a signaling flow diagram of a subscription data management method provided by another embodiment of the present application. The subscription data management method provided by this embodiment includes the following steps:

[0358] The whole process is divided into the adding / updating phase and the deleting phase. First, the adding process is performed:

[0359] Step 1: Same as in the first embodiment, that is, the distributed network node A / centralized node performs intelligent judgment and decision-making.

[0360] Distributed network node A / centralized node performs statistical analysis based on UE business needs, UE current location, UE location change trend, UE service status, UE historical movement trajectory, etc., and can also combine relevant information of other network nodes, such as (network) status, load, capacity and other information, to perform intelligent analysis to predict the network node that the UE will serve next, that is, distributed network node B. Among them, intelligent analysis can use commonly used AI algorithms, such as reinforcement learning algorithms based on graph neural networks, and input information such as distributed network node load, capacity, network status, and user (UE) business needs, user current location and other parameters into the graph neural network to obtain the user's location change trend; then input the user's location change trend, user status, and historical trajectory to obtain the probability of accessing the current distributed network node; finally, determine a distributed network node for service based on parameters such as probability and business needs; the deployment of the AI ​​algorithm can be an independent network element or an existing network element inside the distributed node.

[0361] Step 2. The distributed network node A / centralized node sends a UE event notification message to the distributed network node B to tell the distributed network node B that the UE is to be served.

[0362] Step 3. Distributed network node B sends a subscription data acquisition request message to distributed network node A / centralized node. The message carried includes information such as UE identification (list), and may also include a subscription message (an update event of privacy subscription subscription data, here referring to a subscription message used to indicate an update event of privacy subscription subscription data) to obtain real-time subscription data.

[0363] Step 4. The distributed network node A / centralized node sends a subscription data acquisition response message to the distributed network node B.

[0364] The distributed network node A / centralized node sends the UE's subscription data to the network node to serve the UE, namely the distributed node B, through a response message. The information carried includes the UE's subscription data and may also include a timer (the duration of the subscription data usage. When the timer times out, the UE's subscription data is released).

[0365] The distributed network node B receives the contract data and saves it.

[0366] The other steps are the same as those in the first embodiment, namely: Step 5. The distributed network node B configures / updates the subscription data.

[0367] If it is necessary to subscribe to the update event of the contract data, a private subscription message (here, a subscription message used to indicate the update event of the private subscription contract data) is carried in the response message to obtain real-time contract data.

[0368] Then if an update is required, repeat steps 2-5.

[0369] Finally, if the contract data needs to be deleted, the processing is performed:

[0370] If a timer is carried in step 4, execute step 6: when the timer times out, the distributed network node A / centralized node and the distributed network node B all execute the contract data deletion or mark the contract data as expired or mark the freshness of the contract data (the lower the freshness, the worse the real-time performance of the data).

[0371] If no timer is carried in step 4, the distributed network node B intelligently determines whether the UE's contract data needs to be deleted based on historical information (including historical movement trajectories consisting of number of visits, length of stay, etc.), the currently visited service type, and other information. If the contract data needs to be deleted, execute steps 7-9; otherwise, continue to save the UE's contract data.

[0372] Step 7. Distributed network node B deletes the contract data based on the intelligent judgment result.

[0373] Step 8. Distributed network node B sends a subscription data unsubscription message to distributed network node A / centralized node (meaning no longer subscribing, here referring to a message used to indicate unsubscribing from subscription data).

[0374] Step 9. The distributed network node A / centralized node receives the request message (here refers to the contract data unsubscribe message), performs corresponding operations (such as unsubscribe), and then sends a response message (here refers to the contract data unsubscribe response message).

[0375] Exemplarily, embodiment three (the subscription data is stored in a centralized node or a distributed network node representative (herein, a network node having the ability to manage the target network node) that governs the distributed network node to provide services; this embodiment includes a distributed network node A / centralized node 1 (herein, an initial network node), a distributed network node C / centralized node 2 (herein, a network node having the ability to manage the target network node), and a distributed network node D (herein, a target network node); the UE here is at least one.)

[0376] See also Figure 7 As shown, Figure 7 A signaling flow diagram of a subscription data management method provided by another embodiment of the present application. The subscription data management method provided by this embodiment includes the following steps:

[0377] The whole process is divided into the adding / updating phase and the deleting phase. First, the adding process is performed:

[0378] Step 1. Distributed network node A / centralized node 1 makes intelligent judgment and decision.

[0379] The distributed network node A / centralized node 1 performs statistical analysis based on UE service requirements, UE current location, UE location change trend, UE service status, UE historical movement trajectory, etc., and can also combine relevant information of other network nodes, such as (network) status, load, capacity and other information, to perform intelligent analysis to predict the network node that the UE will serve next, that is, the distributed network node D. Then, the UE's subscription data is pushed to a designated distributed network node (including the centralized node of the UE's location, or a distributed network node), that is, the centralized node 2 or the distributed network node representative C that governs the distributed network node D that is to provide services, that is, the distributed network node C / centralized node 2.

[0380] Step 2-4. Same as step 2-4 in embodiment 1. That is: Step 2. Distributed network node A / centralized node 1 sends a subscription data notification (message) to distributed network node C / centralized node 2.

[0381] Based on the result of the prediction in step 1, the distributed node A / centralized node 1 pushes the subscription data of the UE to the distributed network node C / centralized node 2. The information carried includes the UE identification (list), the subscription data of the UE, and may also include a timer (the usage duration of the subscription data. When the timer times out, the subscription data of the UE is released; here, the timing indication information is specified, and the timing indication information includes the storage duration of the subscription data of each UE, and for each UE, the timing indication information is used to indicate that when the storage duration is exceeded, the subscription data of the UE is processed by any of the following items: deleting the subscription data of the UE; marking the subscription data of the UE as expired; marking the freshness of the subscription data as low). The determination of the timer value (here including the storage duration or usage duration) is obtained based on the intelligent analysis of the above-mentioned statistical information. The determination of the timer can also be based on information such as the number of visits, duration of stay, and services (type of services currently accessible) of the UE in the current area (which may also include other areas); the retention time of the contract data can be intelligently determined; the intelligent analysis can adopt commonly used AI algorithms, such as reinforcement learning algorithms based on graph neural networks, and input information such as distributed network node load, capacity, network status, and parameters such as the user's business needs and the user's current location into the graph neural network to obtain the user's location change trend and historical movement trajectory (including the number of visits within a period of time, i.e., the number of visits, and the length of each stay, i.e., the length of stay); then the user's location change trend and historical movement trajectory (including the number of visits within a period of time, i.e., the length of each stay) are input to obtain the range and corresponding probability of the long retention time of the contract data; finally, a suitable timer value is determined based on parameters such as probability and business needs.

[0382] Step 3. Distributed network node C / centralized node 2 sends a subscription data notification response (message) to distributed network node A / centralized node.

[0383] After receiving the contract data, the distributed network node C / centralized node 2 saves it and then sends a response message.

[0384] Step 4. Distributed network node C / centralized node 2 configures / updates contract data.

[0385] If it is necessary to subscribe to the update event of the contract data, a private subscription message (here, a subscription message used to indicate the update event of the private subscription contract data) is carried in the response message to obtain real-time contract data.

[0386] Then if an update is required, repeat steps 2-4.

[0387] Step 5. Distributed network node D sends a subscription data acquisition request message to distributed network node C / centralized node 2.

[0388] Step 6. The distributed network node C / centralized node 2 sends a subscription data acquisition response message to the distributed network node D.

[0389] The distributed network node currently serving, i.e., distributed network node D, needs the contract data of the UE, such as the need to obtain MM contract data when the UE accesses or the need to obtain SM contract data when the UE session is established, etc., and sends a request message to the centralized node 2 / distributed node C to obtain the contract data, and the information carried includes SUPI, requested contract data type and other information. It is carried to the distributed network node D through a response message. The process of obtaining the contract data requires collaboration between network nodes, such as obtaining the UDM address information of the distributed network node C / centralized node 2 from the local NRF, and then initiating a signaling message to obtain the contract data, or obtaining the contract data from the local UDM to the distributed network node C / centralized node 2 UDM, etc., which will not be expanded or limited.

[0390] Step 7-10. Same as step 5-8 in the first embodiment, that is, finally, if the contract data needs to be deleted, the processing is executed:

[0391] If a timer is carried in step 2, step 7 is executed: when the timer times out, the distributed network node A / centralized node 1 and the distributed network node C / centralized node 2 both execute the contract data deletion or mark the contract data as expired or mark the freshness of the contract data (the lower the freshness, the worse the real-time performance of the data).

[0392] If in step 2, no timer is carried, the distributed network node C / centralized node 2 intelligently determines whether the UE's contract data needs to be deleted based on historical information (including historical movement trajectories consisting of number of visits, length of stay, etc.), the currently visited service type, and other information. If the contract data needs to be deleted, execute steps 8-10; otherwise, continue to save the UE's contract data.

[0393] Step 8. Distributed network node C / centralized node 2 deletes the contract data based on the intelligent judgment result.

[0394] Step 9. Distributed network node C / centralized node 2 sends a subscription data unsubscription message to distributed network node A / centralized node (meaning no longer subscribe, here refers to a message used to indicate unsubscription of subscription data).

[0395] Step 10. The distributed network node A / centralized node 1 receives the request message (here refers to the contract data unsubscribe message), performs corresponding operations (such as unsubscribe), and then sends a response message (here refers to the contract data unsubscribe response message).

[0396] Exemplary, embodiment 4 (the subscription data is stored in a centralized node or a distributed network node representative (herein, a network node having the ability to manage the target network node) that governs the distributed network node to provide services; this embodiment includes a distributed network node A / centralized node 1 (herein, an initial network node), a distributed network node C / centralized node 2 (herein, a network node having the ability to manage the target network node), and a distributed network node D (herein, a target network node); the UE here is at least one.)

[0397] See also Figure 8 As shown, Figure 8 A signaling flow diagram of a subscription data management method provided in another embodiment of the present application. The subscription data management method provided in this embodiment includes the following steps:

[0398] The whole process is divided into the adding / updating phase and the deleting phase. First, the adding process is performed:

[0399] Step 1. is the same as step 1 in the third embodiment, that is, the distributed network node A / centralized node 1 performs intelligent judgment and decision-making.

[0400] The distributed network node A / centralized node 1 performs statistical analysis based on UE service requirements, UE current location, UE location change trend, UE service status, UE historical movement trajectory, etc., and can also combine relevant information of other network nodes, such as (network) status, load, capacity and other information, to perform intelligent analysis to predict the network node that the UE will serve next, that is, the distributed network node D. Then, the UE's subscription data is pushed to a designated distributed network node (including the centralized node of the UE's location, or a distributed network node), that is, the centralized node 2 or the distributed network node representative C that governs the distributed network node D that is to provide services, that is, the distributed network node C / centralized node 2.

[0401] Step 2-5. The same as step 2-5 in the second embodiment. That is: Step 2. The distributed network node A / centralized node 1 sends a UE event notification message to the distributed network node C / centralized node 2 to tell the distributed network node B that it will serve the UE.

[0402] Step 3. Distributed network node C / centralized node 2 sends a contract data acquisition request message to distributed network node A / centralized node 1. The message carried includes information such as UE identification (list), and may also include a subscription message (an update event of privacy subscription contract data, here referring to a subscription message used to indicate an update event of privacy subscription contract data) to obtain real-time contract data.

[0403] Step 4. Distributed network node A / centralized node 1 sends a subscription data acquisition response message to distributed network node C / centralized node 2.

[0404] Distributed network node A / centralized node 1 sends the UE's subscription data to distributed network node C / centralized node 2 via a response message. The information carried includes the UE's subscription data and may also include a timer (the duration of the subscription data usage. When the timer times out, the UE's subscription data is released).

[0405] The distributed network node C / centralized node 2 receives the contract data and saves it.

[0406] Step 5. Distributed network node C / centralized node 2 configures / updates the contract data.

[0407] If it is necessary to subscribe to the update event of the contract data, a private subscription message (here, a subscription message used to indicate the update event of the private subscription contract data) is carried in the response message to obtain real-time contract data.

[0408] Then if an update is required, repeat steps 2-5.

[0409] Step 6-7. Same as step 5-6 in embodiment 3. That is: Step 6. Distributed network node D sends a subscription data acquisition request message to distributed network node C / centralized node 2.

[0410] Step 7. The distributed network node C / centralized node 2 sends a subscription data acquisition response message to the distributed network node D.

[0411] The distributed network node currently serving, i.e., distributed network node D, needs the contract data of the UE, such as the need to obtain MM contract data when the UE accesses or the need to obtain SM contract data when the UE session is established, etc., and sends a request message to the centralized node 2 / distributed node C to obtain the contract data, and the information carried includes SUPI, requested contract data type and other information. It is carried to the distributed network node D through a response message. The process of obtaining the contract data requires collaboration between network nodes, such as obtaining the UDM address information of the distributed network node C / centralized node 2 from the local NRF, and then initiating a signaling message to obtain the contract data, or obtaining the contract data from the local UDM to the distributed network node C / centralized node 2 UDM, etc., which will not be expanded or limited.

[0412] Steps 8-11. Same as steps 6-9 in Example 2. That is: if a timer is carried in step 4, step 8 is executed: when the timer times out, the distributed network node A / centralized node 1 and the distributed network node C / centralized node 2 both execute the contract data deletion or mark the contract data as expired or mark the freshness of the contract data (the smaller the freshness, the worse the real-time performance of the data).

[0413] If in step 4, no timer is carried, the distributed network node C / centralized node 2 intelligently determines whether the UE's contract data needs to be deleted based on historical information (including historical movement trajectories consisting of number of visits, length of stay, etc.), the currently visited service type, and other information. If the contract data needs to be deleted, execute steps 9-11; otherwise, continue to save the UE's contract data.

[0414] Step 9. Distributed network node C / centralized node 2 deletes the contract data based on the intelligent judgment result.

[0415] Step 10. The distributed network node C / centralized node 2 sends a subscription data unsubscription message to the distributed network node A / centralized node (which means no longer subscribing, here referring to a message used to indicate the cancellation of subscription data).

[0416] Step 11. The distributed network node A / centralized node 1 receives the request message (here refers to the contract data unsubscribe message), performs corresponding operations (such as unsubscribe), and then sends a response message (here refers to the contract data unsubscribe response message).

[0417] Processing method 2, request mode contract data acquisition processing method, is described in detail through at least two embodiments below.

[0418] Exemplary embodiment 5 (the subscription data is stored in the distributed network node to provide services, that is, the target network node; this embodiment includes a distributed network node B (herein, the target network node), a distributed network node A / centralized node (herein, the initial network node); the UE here is at least one.)

[0419] See also Fig. 9 As shown, Fig. 9 This is a signaling flow diagram of a subscription data management method provided by another embodiment of the present application. The subscription data management method provided by this embodiment includes the following steps:

[0420] The whole process is divided into the adding / updating phase and the deleting phase. First, the adding process is performed:

[0421] Step 1. Distributed network node B makes intelligent judgment and decision.

[0422] The currently serving distributed network node, i.e., distributed network node B, intelligently determines whether the UE's contract data should be obtained based on information such as the number of visits, stay time, and currently visited services of the UE in the current area. If necessary, the home network node / centralized node / other distributed network nodes actively obtain the UE's contract data and save the UE's contract data for use in subsequent process processing. In this way, there is no need to frequently obtain the UE's contract data from the centralized node / other distributed network nodes to save signaling overhead and reduce latency.

[0423] Among them, intelligent analysis can adopt commonly used AI algorithms, such as reinforcement learning algorithms based on graph neural networks, and input information such as the load, capacity, network status of distributed network node B, and parameters such as the user's business needs and the user's current location into the graph neural network to obtain the user's location change trend and historical movement trajectory; then input the user's location change trend and historical movement trajectory (including the number of visits within a period of time and the length of each stay) to obtain the probability of obtaining the contract data; finally, determine whether it is necessary to obtain the contract data based on the probability.

[0424] Step 2. Distributed network node B sends a subscription data acquisition request message to distributed node A / centralized node 1 to obtain the subscription data of the UE. The information carried includes the UE identifier (list), and may also include a privacy subscription message (if you need to subscribe to the update event of the subscription data), a timer (the duration of the subscription data usage. When the timer times out, the subscription data of the UE is released). The determination of the timer can also be based on the number of visits, stay time, service and other information of the UE in the current area, and intelligently determine the storage time of the subscription data.

[0425] Step 3. Distributed network node A / centralized node 1 sends a subscription data acquisition response message to distributed network node B.

[0426] The distributed node A / centralized node 1 sends a response message, which carries information including UE identification (list), UE subscription data, and the like.

[0427] The other steps are the same as those in the first embodiment, namely: Step 4. The distributed network node B configures / updates the subscription data.

[0428] If it is necessary to subscribe to the update event of the contract data, a private subscription message (here, a subscription message used to indicate the update event of the private subscription contract data) is carried in the response message to obtain real-time contract data.

[0429] Then if an update is required, repeat steps 2-4.

[0430] Finally, if the contract data needs to be deleted, the processing is performed:

[0431] If a timer is carried in step 2, step 5 is executed: when the timer times out, the distributed network node A / centralized node and the distributed network node B all execute the contract data deletion or mark the contract data as expired or mark the freshness of the contract data (the lower the freshness, the worse the real-time performance of the data).

[0432] If no timer is carried in step 2, the distributed network node B intelligently determines whether the UE's contract data needs to be deleted based on historical information (including historical movement trajectories consisting of number of visits, length of stay, etc.), the currently visited service type, and other information. If the contract data needs to be deleted, execute steps 6-8; otherwise, continue to save the UE's contract data.

[0433] Step 6. Distributed network node B deletes the contract data based on the intelligent judgment result.

[0434] Step 7. Distributed network node B sends a subscription data unsubscription message to distributed network node A / centralized node (meaning no longer subscribe, here refers to the message used to indicate the cancellation of subscription data).

[0435] Step 8. The distributed network node A / centralized node receives the request message (here refers to the contract data unsubscribe message), performs corresponding operations (such as unsubscribe), and then sends a response message (here refers to the contract data unsubscribe response message).

[0436] Exemplary, embodiment six (the subscription data is stored in a centralized node or a distributed network node representative (herein, a network node having the ability to manage the target network node) that governs the distributed network node to provide services; this embodiment includes a distributed network node A / centralized node 1 (herein, an initial network node), a distributed network node C / centralized node 2 (herein, a network node having the ability to manage the target network node), and a distributed network node D (herein, a target network node); the UE here is at least one.)

[0437] See also Fig.10 As shown, Fig.10 A signaling flow diagram of a subscription data management method provided by another embodiment of the present application. The subscription data management method provided by this embodiment includes the following steps:

[0438] The whole process is divided into the adding / updating phase and the deleting phase. First, the adding process is performed:

[0439] Step 1-4. Same as step 1-4 in embodiment 5. That is: Step 1. Distributed network node C / centralized node 2 performs intelligent judgment and decision.

[0440] The distributed network node C / centralized node 2 intelligently determines whether the UE's contract data should be obtained based on the UE's visit times, stay time, current visited services and other information in the current area. If necessary, the home network node / centralized node / other distributed network nodes actively obtain the UE's contract data and save the UE's contract data for subsequent process processing. In this way, there is no need to frequently obtain the UE's contract data from the centralized node / other distributed network nodes to save signaling overhead and reduce latency.

[0441] Among them, intelligent analysis can adopt commonly used AI algorithms, such as reinforcement learning algorithms based on graph neural networks, and input information such as the load, capacity, network status of distributed network node C / centralized node 2, and parameters such as the user's business needs and the user's current location into the graph neural network to obtain the user's location change trend and historical movement trajectory; then input the user's location change trend and historical movement trajectory (including the number of visits within a period of time and the length of each stay) to obtain the probability of obtaining the contract data; finally, determine whether it is necessary to obtain the contract data based on the probability.

[0442] Step 2. Distributed network node C / centralized node 2 sends a subscription data acquisition request message to distributed node A / centralized node 1 to obtain the subscription data of the UE. The information carried includes the UE identifier (list), and may also include a privacy subscription message (if it is necessary to subscribe to the update event of the subscription data) and a timer (the duration of the subscription data usage. When the timer times out, the subscription data of the UE is released). The determination of the timer can also be based on the number of visits, stay time, service and other information of the UE in the current area, and intelligently determine the storage time of the subscription data.

[0443] Step 3. Distributed network node A / centralized node 1 sends a subscription data acquisition response message to distributed network node C / centralized node 2.

[0444] The distributed node A / centralized node 1 sends a response message, which carries information including UE identification (list), UE subscription data, and the like.

[0445] Step 4. Distributed network node C / centralized node 2 configures / updates contract data.

[0446] If it is necessary to subscribe to the update event of the contract data, a private subscription message (here, a subscription message used to indicate the update event of the private subscription contract data) is carried in the response message to obtain real-time contract data.

[0447] Then if an update is required, repeat steps 2-4.

[0448] Step 5-6. Same as step 5-6 of embodiment 3. That is: Step 5. Distributed network node D sends a subscription data acquisition request message to distributed network node C / centralized node 2.

[0449] Step 6. The distributed network node C / centralized node 2 sends a subscription data acquisition response message to the distributed network node D.

[0450] The distributed network node currently serving, i.e., distributed network node D, needs the contract data of the UE, such as the need to obtain MM contract data when the UE accesses or the need to obtain SM contract data when the UE session is established, etc., and sends a request message to the centralized node 2 / distributed node C to obtain the contract data, and the information carried includes SUPI, requested contract data type and other information. It is carried to the distributed network node D through a response message. The process of obtaining the contract data requires collaboration between network nodes, such as obtaining the UDM address information of the distributed network node C / centralized node 2 from the local NRF, and then initiating a signaling message to obtain the contract data, or obtaining the contract data from the local UDM to the distributed network node C / centralized node 2 UDM, etc., which will not be expanded or limited.

[0451] The steps of the deletion phase are the same as those of the processing phase in Example 1. That is, finally, if the contract data needs to be deleted, the processing process is executed:

[0452] If a timer is carried in step 2, step 7 is executed: when the timer times out, the distributed network node A / centralized node and the distributed network node C / centralized node 2 both execute the contract data deletion or mark the contract data as expired or mark the freshness of the contract data (the lower the freshness, the worse the real-time performance of the data).

[0453] If in step 2, no timer is carried, the distributed network node C / centralized node 2 intelligently determines whether the UE's contract data needs to be deleted based on historical information (including historical movement trajectories consisting of number of visits, length of stay, etc.), the currently visited service type, and other information. If the contract data needs to be deleted, execute steps 8-10; otherwise, continue to save the UE's contract data.

[0454] Step 8. Distributed network node C / centralized node 2 deletes the contract data based on the intelligent judgment result.

[0455] Step 9. Distributed network node C / centralized node 2 sends a subscription data unsubscription message to distributed network node A / centralized node 1 (which means no longer subscribing, here referring to a message used to indicate unsubscribing from subscription data).

[0456] Step 10. The distributed network node A / centralized node 1 receives the request message (here refers to the contract data unsubscribe message), performs corresponding operations (such as unsubscribe), and then sends a response message (here refers to the contract data unsubscribe response message).

[0457] Therefore, the contract data management method provided in the present application includes the addition and update of contract data, and the processing of contract data (at least including operations such as deletion).

[0458] The phase of adding and updating contract data:

[0459] 1. The distributed network node or the centralized node intelligently predicts the network node that the UE will serve next.

[0460] 1.1 Push the subscription data of the UE to the network node that will serve the UE next to save / update the subscription data.

[0461] 1.2. Push the UE's subscription data to a designated centralized node / distributed network node to save / update the subscription data.

[0462] 1.3. Send the UE event notification message to the distributed network node that will provide the service.

[0463] 1.3.1. The distributed network node that will provide the service obtains the contract data to save / update the contract data.

[0464] 1.4 Send the UE event notification message to the centralized node / distributed network node that governs the distributed nodes that will provide the service.

[0465] 1.4.1 The centralized node / distributed network node that governs the distributed nodes that will provide services obtains the contract data to save / update the contract data.

[0466] Contract data processing stages:

[0467] 2.1 Based on the saved timer, delete the contract data or mark the contract data as expired or mark the freshness of the contract data;

[0468] 2.2 Based on the historical movement trajectory, business type and other information, it is intelligently determined that the contract data needs to be deleted, and the contract data is sent to the subscription message to delete the corresponding contract data.

[0469] Therefore, this application solves the problem of intelligent management of contract data for 6G distributed architecture, and provides a feasible intelligent management solution for contract data under distributed network architecture. The management solution for contract data is based on intelligent design, which reduces signaling interaction delay and saves network resources.
