Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to a data update method, a data update device, an electronic device, and a computer program product. Background Technology

[0002] Some Network Function (NF) static data, such as user profiles, and dynamic data, such as context data, are stored in the network database (NF). When the database NF changes, such as during restoration, update, or mitigation, the static data of the NF can be migrated accordingly. However, the temporary data of the NF is based on the new network conditions and is dynamically changing, so it needs to be rebuilt later. This affects the subsequent development of network services (i.e., the context needs to be rebuilt before services can be launched).

[0040] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0041] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced without one or more of the specific details described, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known structures, methods, apparatuses, implementations, materials, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0042] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, or in one or more software-hardened modules, or in different network and / or processor devices and / or microcontroller devices.

[0043] In this article, it's important to understand the following terms: The Unified Data Repository (UDR) primarily stores subscription and policy data for the UDM and PCF. The Unified Data Management (UDM) mainly manages user subscription data and controls roaming. The Network Exposure Function (NEF) primarily exposes 5G network capabilities to external networks, such as outputting terminal location information; it can also receive external information and manage updates to certain network information. The Policy Control Function (PCF) primarily manages user control policies, including Quality of Service (QoS) control and service access control.

[0044] Because the dynamic data of the database NF in the network is based on new network conditions and changes dynamically, it needs to be re-established later, which affects the subsequent development of network services. In particular, when the mapping relationship between the network function group ID (NF group ID) and user identity is missing, such as the mapping relationship between the UDR group ID (UDR groupId), UDM group ID (UDM groupId), and PCF group ID (PCF groupId) and user ID, it may lead to routing to the wrong UDR / UDM / PCF, resulting in serious problems such as user equipment (UE) registration failure and UE service request failure.

[0045] Based on this, according to embodiments of the present disclosure, a data update method, a data update device, an electronic device, and a computer program product are proposed.

[0046] In this example embodiment, a data update method is first provided. This data update method is applied to a first network function, which can be a UDR consumer, such as a PCF, NEF, or UDM. The data update method of this disclosure can be implemented using a server or a terminal device. The terminal described in this disclosure can include mobile terminals such as mobile phones, tablets, laptops, handheld computers, and personal digital assistants (PDAs), as well as fixed terminals such as desktop computers. Figure 1A schematic diagram illustrating a data update method flow according to some embodiments of the present disclosure is provided. (Reference) Figure 1 The data update method may include the following steps:

[0047] Step S110: Receive the network function dynamic data update notification sent by the Unified Data Storage Function (UDR) and update the local network function group identifier and user identity mapping table; the network function dynamic data update notification is generated by the Unified Data Storage Function (UDR) when it detects a change in dynamic data.

[0048] According to some exemplary embodiments of this disclosure, a network function dynamic data update notification may be a dynamic data update notification triggered when the UDR detects a change in dynamic data in a network function. The network function group identifier to user identity mapping table may be a data table representing the mapping relationship between group identifiers and user identity identifiers for each network function. This table can be used to route to the corresponding network function in network communication. For example, the network function group identifier to user identity mapping table may include the mapping relationship between UDR group identifier (UDR groupId), UDM group identifier (UDM groupId), and PCF group identifier (PCF groupId) and user identity identifiers (user IDs), respectively.

[0049] Based on the UDR data recovery scheme, when the UDR detects a change in its dynamic data, such as a change in the UDR group ID–user identity mapping table, it will generate a network function dynamic data update notification and send it to the UDR consumer, i.e., the first network function, such as UDM, PCF, and NEF. Upon receiving the network function dynamic data update notification, the UDR consumer can update its local network function group ID–user identity mapping table to complete the dynamic data update operation for the UDR consumer.

[0050] According to the data update method in this example embodiment, after the Unified Data Storage Function (UDR) detects a change in dynamic data, it sends a network function dynamic data update notification to the first network function. Upon receiving the network function dynamic data update notification, the first network function updates its local network function group identifier and user identity mapping table to achieve dynamic data update of the network function.

[0051] The data update method in this example embodiment will be further explained below.

[0052] In one exemplary embodiment of this disclosure, a network function registration request is sent to the network repository function, and a notification address of a first network function is received from the network repository function (NRF); the notification address of the first network function is then sent to the unified data storage function (UDR).

[0053] The network function registration request can be a terminal registration request sent by the first network function to the Network Repository Function (NRF). The main function of the NRF is to manage all NFs that support service-oriented interfaces in 5G. These NFs must first register with the NRF, and when NFs look up each other, they do so by querying the NRF. The notification address of the first network function can be the endpoint address of the first network function (NF A).

[0054] Figure 2 The diagram schematically illustrates the overall flowchart of dynamic data updates for network functions according to an exemplary embodiment of the present disclosure. In step S200, a first network function (UDR consumer) sends a network function registration request to the NRF to register a notification address via the NRF. Based on the received network function registration request from the UDR consumer, the NRF returns the notification address of the NRF A to the first network function.

[0055] In step S201, the first network function sends its notification address to the UDR and informs the UDR of its identification (ID), so that the UDR can subsequently send notifications to the first network function based on the notification address corresponding to the first network function's identification. The first network function registers its notification address with the URF and informs the UDR of the registered notification address, enabling the UDR to send notifications to the first network function based on the notification address in subsequent processes.

[0056] In one exemplary embodiment of this disclosure, the most recent synchronization time and a reset identifier are stored. The most recent synchronization time can be the time information of the most recent data synchronization operation performed across different network functions. The reset identifier (Reset-ID) can be an identifier corresponding to the most recent synchronization time, used to uniquely identify a data synchronization operation.

[0057] Continue to refer to Figure 2In step S202, the first network function stores the most recent synchronization time and reset identifier. After storing the above information, NF A can determine the time of the most recent data update operation and the unique identifier of the most recent data update operation based on the most recent synchronization time and reset identifier. The most recent synchronization time and reset identifier are used to record every data update operation of the network function.

[0058] In one exemplary embodiment of this disclosure, step S110, receiving a network function dynamic data update notification sent by the Unified Data Storage Function (UDR), includes: receiving the network function dynamic data update notification based on the notification address of the first network function, wherein the notification address of the first network function is obtained from the address notification sent by the first network function or by querying the Network Repository Function (NRF).

[0059] The network function dynamic data update notification can be a notification message sent by the UDR to the UDR consumer (such as the first network function) to instruct the UDR consumer to perform a dynamic data update operation. The address notification can be a notification sent by the first network function to the unified data storage function to inform the first network function of its own notification address, i.e., the first network function's notification address.

[0060] Continue to refer to Figure 2 In step S203, when the UDR detects a change in dynamic data, it will trigger the generation of a network function dynamic data update notification. The network function dynamic data update notification may include the updated network function group identifier and user identity mapping table when the mapping table between the UDR's network function group identifier and user identity changes.

[0061] Obtain the notification address of the first network function and send a network function dynamic data update notification to the first network function. If the UDR has already obtained the notification address of the first network function from the address notification sent by the first network function, it directly sends the network function dynamic data update notification to the first network function based on the notification address of the first network function.

[0062] If the UDR does not obtain the notification address for the first network function, then continue to refer to... Figure 2 In step S204, the UDR can look up the notification address corresponding to the UDR consumer ID in the NRF. The UDR can perform an address lookup operation in the Network Repository Function (NRF) based on the function identifier of the first network function to obtain the notification address of the first network function. The function identifier of the first network function can be a unique identifier of the first network function. The address lookup operation can be an operation performed by the first network function based on the NRF to query the notification address.

[0063] UDR sends a network function dynamic data update notification to the first network function via the notification address of the first network function. Subsequently, the first network function can update its local network function group identifier and user identity mapping table according to the above notification to realize dynamic data update operation.

[0064] In one exemplary embodiment of this disclosure, updating the local network function group identifier and user identity mapping table includes: obtaining the updated network function group identifier and user identity mapping table, and updating the local network function group identifier and user identity mapping table according to the updated network function group identifier and user identity mapping table.

[0065] Continue to refer to Figure 2 In step S205, the UDR sends a network function dynamic data update notification to the first network function. If the network function dynamic data update notification contains an updated network function group identifier and user identity mapping table, then after receiving the network function dynamic data update notification, the first network function will update its local network function group identifier and user identity mapping table according to the updated network function group identifier and user identity mapping table contained in the notification, thereby realizing the dynamic data update of the first network function.

[0066] In one exemplary embodiment of this disclosure, the Network Function Dynamic Data Update Notification is generated in the following manner: the Network Function Dynamic Data Update Notification is generated when the Unified Data Storage Function (UDR) detects an update to the local Network Function Group Identifier and User Identity Mapping Table, or the Network Function Dynamic Data Update Notification is generated when the Unified Data Storage Function (UDR) obtains the updated Network Function Group Identifier and User Identity Mapping Table from the Network Repository Function (NRF).

[0067] Since there are various scenarios for changes in UDR dynamic data, different scenarios will trigger the generation of different types of network function dynamic data update notifications. Therefore, the notification content of the network function dynamic data update notification includes the specific notification trigger type and the specific content of the dynamic data corresponding to different notification trigger types.

[0068] Specifically, dynamic data change scenarios include one or more of the following: the unified data storage function malfunctions or restarts; data is migrated from the current unified data storage function to a new unified data storage function; the unified data storage function detects a change in the mapping table between network function group identifiers and user identities.

[0069] Among them, dynamic data change scenarios can be the specific circumstances that cause dynamic data to change.

[0070] The UDR detects specific dynamic data changes that could lead to corruption, missing, or inconsistencies in dynamic data, including: a UDR malfunction or restart; data migration from the current UDR to a new UDR; and a change detected by the UDR in the network function group identifier-user identity mapping table. The third scenario mentioned above may cause changes to the UDR's network function group identifier-user identity mapping table. When the UDR detects these dynamic data changes, it will generate different types of network function dynamic data update notifications.

[0071] For example, when the notification trigger type is a network function dynamic data update notification triggered based on a change in the network function group identifier and user identity mapping table, the notification content can directly carry the specific notification trigger type and the new network function group identifier and user identity mapping table. If the notification content carries the new network function group identifier and user identity mapping table, then after receiving the network function dynamic data update notification, the first network function can directly update its own network function group identifier and user identity mapping table based on the new table, ensuring that routing is performed to different network functions based on the updated table.

[0072] If the network function dynamic data update notification is not triggered by the UDR updating the local network function group identifier and user identity mapping table, then continue to refer to... Figure 2 In step S206, the first network function can perform a query operation based on the NRF to retrieve the updated network function group identifier and user identity mapping table from the NRF. This is generally used when the notification content in step S205 does not carry a new corresponding table. When the first network function retrieves the updated table from the NRF, it can update the locally stored network function group identifier and user identity mapping table to complete the dynamic data update operation.

[0073] In summary, the data update method disclosed herein, applied to a first network function, includes: receiving a network function dynamic data update notification sent by a Unified Data Storage Function (UDR), and updating the local network function group identifier-user identity mapping table; the network function dynamic data update notification is generated by the Unified Data Storage Function (UDR) when it detects a change in dynamic data. On one hand, after the UDR detects a change in dynamic data, the Unified Data Storage Function can send a network function dynamic data update notification to the first network function. On the other hand, upon receiving the network function dynamic data update notification, the first network function can directly obtain the updated network function group identifier-user identity mapping table from the notification, or query the updated network function group identifier-user identity mapping table from the Network Repository Function (NRF), thus realizing the dynamic data update operation.

[0074] Furthermore, this example embodiment also provides a data update method applied to a unified data storage function (UDR). The data update method of this disclosure can be implemented using a server or a terminal device. Figure 3 The illustration shows a schematic diagram of a data update method flow according to some embodiments of the present disclosure.

[0075] refer to Figure 3 The data update method may include the following steps:

[0076] Step S310: When a change in dynamic data is detected, a network function dynamic data update notification is sent to the first network function. The network function dynamic data update notification is used to update the mapping relationship table between the network function group identifier and the user identity of the first network function.

[0077] When the UDR detects a change in dynamic data, such as a change in the mapping table between network function group identifiers and user identities, it can send a network function dynamic data update notification to the first network function, which refers to the UDR consumers. Subsequently, the first network function updates its local mapping table between network function group identifiers and user identities.

[0078] According to the data update method in this example embodiment, when the Unified Data Storage Function (UDR) detects a change in dynamic data, it sends a network function dynamic data update notification to the first network function. The first network function can then update its local network function group identifier and user identity mapping table to achieve dynamic data update operation.

[0079] The data update method in this example embodiment will be further explained below.

[0080] In one exemplary embodiment of this disclosure, step S310, sending a network function dynamic data update notification to the first network function, includes: obtaining the notification address of the first network function, wherein the notification address of the first network function is obtained from the address notification sent by the first network function or obtained by querying the network repository function NRF; and sending a network function dynamic data update notification to the first network function based on the notification address of the first network function.

[0081] After determining the notification address of the first network function, the UDR can send a network function dynamic data update notification to the first network function based on the notification address. Upon receiving the network function dynamic data update notification, the first network function can update its local network function group identifier and user identity mapping table, completing the dynamic data update operation. The method for determining the notification address of the first network function has been explained in detail above and will not be repeated here.

[0082] In one exemplary embodiment of this disclosure, step S310, detecting a change in dynamic data, includes: detecting an update to the mapping table between network function group identifiers and user identities in the Unified Data Storage Function (UDR), or obtaining the updated mapping table between network function group identifiers and user identities from the Network Repository Function (NRF).

[0083] When the UDR detects a change in dynamic data, it can send a network function dynamic data update notification to the first network function. Dynamic data changes include one or more of the following scenarios: a unified data storage function malfunctions or restarts; data is migrated from the current unified data storage function to a new unified data storage function; the unified data storage function detects a change in the mapping table between network function group identifiers and user identities.

[0084] Because dynamic data changes can occur in various scenarios, different scenarios will trigger the generation of Network Function Group (NFG) dynamic data update notifications containing different content. For example, when the Unified Data Storage Function (UDR) detects a change in the mapping table between NFG identifiers and user identities, it will generate a NFG dynamic data update notification containing the updated NFG identifier-user identity mapping table. Alternatively, if the UDR obtains the updated NFG identifier-user identity mapping table from the Network Repository Function (NRF), it can also generate a NFG dynamic data update notification containing the updated NFG identifier-user identity mapping table. Through these steps, the UDR can generate corresponding NFG dynamic data update notifications based on different dynamic data change scenarios.

[0085] In addition, if other dynamic data changes trigger the UDR to generate a network function dynamic data update notification, the network function dynamic data update notification may not carry the network function group identifier and user identity mapping table. In this case, the UDR can obtain the updated network function group identifier and user identity mapping table from the network repository function NRF.

[0086] It should be noted that although the steps of the method in this invention are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.

[0087] Furthermore, in this example embodiment, a data update apparatus is also provided. (See reference...) Figure 4 The data update device 400 may include: a first data update module 410.

[0088] Specifically, the first data update module 410 is used to receive network function dynamic data update notifications sent by the Unified Data Storage Function (UDR) and update the local network function group identifier and user identity mapping table; the network function dynamic data update notification is generated by the Unified Data Storage Function (UDR) when it detects changes in dynamic data.

[0089] In one exemplary embodiment of this disclosure, the data update device 400 further includes an address determination module, configured to: send a network function registration request to the network repository function (NRF), receive a notification address of a first network function returned by the network repository function (NRF), and send the notification address of the first network function to the unified data storage function (UDR).

[0093] In one exemplary embodiment of this disclosure, the relationship table update unit includes a relationship table acquisition subunit, used to: acquire the updated network function group identifier and user identity mapping relationship table from the network function dynamic data update notification, or obtain the updated network function group identifier and user identity mapping relationship table by querying the network repository function NRF.

[0094] In one exemplary embodiment of this disclosure, the first data update module 410 includes a first notification generation unit, configured to generate a network function dynamic data update notification in the following manner: the network function dynamic data update notification is generated when the unified data storage function UDR detects an update to the local network function group identifier and user identity mapping table, or the network function dynamic data update notification is generated when the unified data storage function UDR obtains the updated network function group identifier and user identity mapping table from the network repository function NRF.
