In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the application, many technical details are provided for readers to better understand the application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can also be realized. The division of the following embodiments is for the convenience of description, and should not constitute any limitation to the specific implementation of the present application, and the embodiments can be combined and referred to each other on the premise of no contradiction.

The implementation details of the data caching method recorded in the present application will be described in detail below in conjunction with specific embodiments. The following content is only the implementation details provided for easy understanding, and is not necessary for implementing this solution.

The first aspect of the embodiment of the present application relates to a data caching method, which is applied to a unified data management network element. The specific process of the data caching method refers to FIG. 1, at least including but not limited to the following steps:

Step 101, receiving a dynamic information caching request from a preset functional network element.

Specifically, after the 5G service-based architecture is put into use, the preset function network element will connect the terminal device under its jurisdiction to the 5G service-based architecture after receiving the access request of the terminal device according to the assigned task area or task type. After the preset function network element detects that the terminal device is online, it requests the unified data management network element to cache the dynamic information of the terminal device through the customized service interface based on the specified communication protocol and syntax. , UDM) receives a dynamic information caching request from a preset function network element, where the dynamic information caching request includes terminal dynamic information.

It is worth mentioning that the dynamic information cache request received by the unified data management network element may also include the user permanent identifier corresponding to the terminal device, the network element identifier of the network element with preset functions, etc., which are used to distinguish the functions corresponding to the terminal dynamic information For the identification information of network elements and terminal devices, this embodiment does not specifically limit the identification information selected in specific applications.

Step 102, cache the terminal dynamic information according to the dynamic information caching request.

Specifically, after the unified data management network element receives the dynamic information cache request from the preset function network element through the service interface, it creates a storage address and a corresponding blank file for the terminal dynamic information according to the identification information carried in the dynamic information cache request , and then store the terminal information with storage in the database corresponding to the specified address or in the created blank file to complete the caching of the terminal dynamic information. By using unified data management network elements to store terminal dynamic information, the secure storage of terminal dynamic information is realized without deploying additional network elements or databases, ensuring data security and reliability.

For example, the preset functional network element is AMF, and the unified data management network element UDM receives the dynamic information cache request and related data transmitted from the AMF through the preset service port, and according to the AMF identifier in the dynamic information cache request and the online The user permanent identifier corresponding to the terminal device assigns the corresponding storage address for the terminal dynamic information in the local database, and then stores the terminal dynamic information cached by the AMF request in the form of a document to the allocated storage address, and according to the AMF ID and user The permanent identifier establishes a storage address index to complete the storage of terminal dynamic information.

It is worth mentioning that the preset functional network elements can be network elements with different functions such as the access mobile management network element AMF, the session management network element SMF, and the short message network element SMSF. Select an appropriate functional network element according to the type, and this embodiment does not limit the specific selection of the functional network element.

In an example, after the unified data management network element caches the dynamic information of the terminal according to the dynamic information cache request, it also includes: receiving a dynamic information deletion request initiated by the preset function network element after the terminal is offline; , to delete the terminal dynamic information. Specifically, the terminal will change its online status according to business needs and business completion status. In order to ensure the continuity of the business, when the terminal is in the online status, it is necessary to store the dynamic information of the terminal, and when the terminal completes business processing, it goes offline. state, there is no need to continue to save terminal dynamic information to avoid meaningless resource occupation. Therefore, after the preset function network element detects that the terminal is offline, it will request the unified data management network element to delete the cached terminal dynamic information. After receiving the dynamic information deletion request through the preset service port, the unified data management network element For the identification information in the information deletion request, for example, the network element identification of the functional network element and the permanent user identifier, the corresponding terminal dynamic information is queried in the local database, and the queried terminal dynamic information is deleted to release the corresponding resources. Through the dynamic information deletion request initiated by the network element according to the preset function after the terminal is offline, the cached dynamic information of the specified terminal is deleted. Through flexible maintenance methods, the resource occupation of meaningless terminal dynamic information cache is avoided, and resource utilization is improved. Rate.

Refer to Figure 2 for the process of terminal dynamic data caching and maintenance according to the terminal online status, including the following steps:

Step S101: a terminal equipment (UE) initiates an initial access request to a preset functional network element (AMF).

Step S102: AMF initiates an initial access request to a unified data management network element (UDM).

Step S103: UDM returns a response to AMF.

Step S104: The AMF locally caches the terminal dynamic information of the UE, and returns an initial access response to the UE.

Step S105: The AMF initiates a dynamic information cache request to the UDM, and the dynamic information cache request carries the user permanent identifier, network element identifier and terminal dynamic information.

Step S106: The UDM returns a terminal dynamic information saving response to the AMF.

Step S107: UE initiates an offline request to AMF.

Step S108: The AMF deletes the cached terminal dynamic information, and returns an offline response to the UE.

Step S109: The AMF initiates a dynamic information deletion request to the UDM, and the dynamic information deletion request carries the user permanent identifier and the network element identifier.

Step S110: The UDM returns a response to the AMF to delete the dynamic information of the terminal.

In another example, after the unified data management network element caches the terminal dynamic information according to the dynamic information cache request, it further includes: receiving a dynamic information update request from a network element with a preset function, wherein the dynamic information update request includes the latest The terminal dynamic information; according to the dynamic information update request, update the cached terminal dynamic information to the latest terminal dynamic information. Specifically, the terminal dynamic information corresponding to the terminal equipment will continue to change with factors such as the business processing process. In order to ensure accurate control of the terminal equipment and business support, the preset function network element will maintain the stored terminal dynamic information in a timely manner. After detecting that the service processing process of the terminal device has entered a new stage, it will update the terminal dynamic information cached by itself, and request the unified data management network element to update the terminal dynamic information. After receiving the dynamic information update request of the preset function network element, the unified data management network element updates the stored terminal dynamic information to the latest terminal dynamic information according to the latest terminal dynamic information and corresponding identification information contained in the dynamic information update request Dynamic Information. According to the dynamic information update request of the preset function network element, the cached terminal dynamic information is updated to the latest terminal dynamic information in time to ensure the timeliness and validity of the terminal dynamic information stored in the unified data management network element, thereby ensuring The terminal dynamic information stored by the data management network element can accurately restore the management and control of the terminal.

Refer to Figure 3 for the process of updating the cached terminal dynamic information, including the following steps:

Step S201: after the terminal equipment UE enters a new service processing stage, it initiates a follow-up process message request.

Step S202: The functional network element AMF updates the dynamic information of the local terminal.

Step S203: AMF returns a response to UE.

Step S204: The AMF initiates a dynamic information update request to the unified data management network element UDM, and the dynamic information update request carries the user permanent identifier, the network element identifier and the latest terminal dynamic information.

Step S205: UDM returns terminal dynamic information update response to AMF.

In another example, after the unified data management network element caches the terminal dynamic information according to the dynamic information cache request, it further includes: setting an update timestamp for the cached terminal dynamic information, where the update timestamp includes the terminal dynamic information last The first moment of an update; when the time interval between the first moment and the current moment is greater than the preset duration, delete the terminal dynamic information. Specifically, after the unified data management network element stores the terminal dynamic information, in order to avoid meaningless resource occupation caused by caching too much terminal dynamic information, the cached terminal dynamic information can also be periodically updated based on the data aging mechanism. Dynamic maintenance. When the unified data management network element caches or updates the terminal dynamic information, it will mark the cached terminal dynamic information with the time stamp of the cache time or update time, and then periodically detect the first time corresponding to the time stamp on the cached terminal dynamic information and the time interval between the current moment, when it is detected that the time interval between the first moment and the current moment is greater than the first preset duration, it is determined that the cached terminal dynamic information has expired, and the cached terminal dynamic information is directly deleted, And release the system resources it occupies. Based on the data aging mechanism, the terminal dynamic information cached by the unified data management network element is regularly dynamically maintained to avoid meaningless resource occupation caused by invalid terminal dynamic information and improve resource utilization.

In one embodiment, the unified data management network element caches the dynamic information of the terminal, including: caching the dynamic information of the terminal, and storing the registration information corresponding to the dynamic information of the terminal; Dynamic maintenance of the entry state; before deleting the terminal dynamic information, it also includes: detecting whether there is corresponding registration information in the terminal dynamic information; if there is no corresponding registration information in the terminal dynamic information, deleting the terminal dynamic information. Specifically, when the unified data management network element caches terminal dynamic information, it also caches the registration information of the terminal device corresponding to the cached terminal dynamic information, establishes a registration information table, and The registration information of the terminal is dynamically maintained through the access state on the Internet. Before deleting the cached terminal dynamic information, the same data management network element can also detect whether the registration information corresponding to the terminal dynamic information to be deleted still exists in the registration information table, and if it is detected that the registration information corresponding to the terminal dynamic information does not exist If it is determined that the terminal device is offline and the terminal dynamic information is invalid, then delete the determined terminal dynamic information to be deleted; if it is detected that the registration information corresponding to the terminal dynamic information still exists, the to-be-deleted Terminal dynamic information, and count the length of time that the terminal dynamic information has not changed, and then report it to the administrator for processing. By storing the corresponding registration information when caching the terminal dynamic information, and dynamically maintaining the registration information according to the access status of the terminal on the preset function network element, and performing expired terminal dynamic information based on the comparison result between the registration information table and the dynamic information table The dynamic maintenance of information avoids accidental deletion of terminal dynamic information that has not expired, and at the same time reduces the resource occupation of terminal dynamic information as much as possible.

Based on the data aging mechanism, the unified data management network element can refer to Figure 4 for the dynamic maintenance process of terminal dynamic data, including the following steps:

Step S301: when updating the cached terminal dynamic information, the unified data management network element UDM sets an update time stamp for the terminal dynamic information.

Step S302: The UDM sets an aging timer for terminal dynamic information.

Step S303: The UDM cyclically inquires the updated timestamp of the terminal dynamic information, and finds out the terminal dynamic information whose corresponding time of the updated timestamp is more than 24 hours away from the current time (time length can be configured).

Step S304: The UDM detects that the registration information corresponding to the terminal dynamic information has been deleted.

Step S305: UDM deletes the terminal dynamic information.

Then step S303 is repeated until all the terminal dynamic information whose time corresponding to the updated timestamp is more than 24 hours away from the current time is processed.

Step 103: After receiving the dynamic information request initiated by the preset function network element after restarting, send the terminal dynamic information to the preset function network element, so that the preset function network element can resume management and control of the terminal according to the terminal dynamic information.

Specifically, after the terminal dynamic information is lost due to the restart of the preset function network element, it requests the terminal dynamic information from the unified data management network element, and the unified data management network element receives the dynamic information initiated by the preset function network element after restarting After the request, according to the identification information in the dynamic information request, for example, the network element identification and the user permanent identifier, the terminal dynamic information requested by the preset function network element is queried. Then, the terminal dynamic information is sent to the preset function network element through the preset service interface, so that the preset function network element can restore the management and control of the terminal according to the terminal dynamic information.

Refer to Figure 5 for the flow chart of how network elements with preset functions recover terminal control, including the following steps:

Step S401: A restart of the default function network element AMF occurs.

Step S402: the unified data management network element UDM initiates a follow-up service request of the terminal device to the AMF.

Step S403: The AMF fails to obtain the dynamic information of the terminal locally, and initiates a dynamic information request to the UDM, and the dynamic information request carries the user permanent identifier and the network element identifier.

Step S404: The UDM returns a terminal dynamic information acquisition response to the AMF.

Step S405: The AMF initiates a follow-up service request to the UE.

Step S406: UE returns a response.

Step S407: AMF updates local terminal dynamic information, and returns a response to UDM.

Step S408: The AMF initiates a dynamic information update request to the UDM, and the dynamic information update request carries the user permanent identifier, the network element identifier, and the latest terminal dynamic information.

Step S409: The UDM returns a terminal dynamic information update response to the AMF.

It is worth mentioning that after the network element with the preset function is restarted, it can actively initiate a follow-up service request on the network side, or initiate a dynamic information request to the unified data management network element after the terminal device initiates a service request, so as to obtain the terminal again. Dynamic information restores management and control of terminal equipment and subsequent business support.

After the functional network element detects that the service processing of the terminal device is offline, it clears the terminal dynamic information cached locally, and sends a dynamic information deletion request to the unified data management network element. The dynamic information deletion request can include the user corresponding to the terminal device The permanent identifier and the network element identifier of the functional network element are used as the identification information of the terminal dynamic information to be deleted, so that the unified data management network element can accurately delete invalid terminal dynamic information, and avoid resource occupation of invalid terminal dynamic information.

It is worth mentioning that the functional network element can be AMF, SMF, SMSF and other network elements, and the specific access network element can be selected according to the service handled by the terminal. This embodiment does not limit the specific selection of the functional network element.
