For the convenience of reading, the technical terms involved in this disclosed solution are briefly introduced below through a table.

Table I

In related technology, after the IoT terminal signs the VN Group of the system, the system obtains session management data, and the session management data is used to identify the signing process of the IoT terminal. For the session management subscription data of the same type of IoT terminal, except for the slight difference in the Internal Group ID in the session management subscription data, other parameters remain the same. In addition, the same IoT terminal can sign up with multiple VN Groups. Based on the above two situations, when a 5G IoT terminal signs multiple VN Groups, UDR will occupy a large amount of storage resources.

Based on the method of using UDR to save the session management contract data of IoT terminals in related technologies, related technologies also provide the following two methods to obtain 5G things through query and subscription. The method of session management of contract data for networked terminals.

Obtain session management subscription data through the query interface. The specific steps for implementation are as follows:

1. SMF sends a query request to UDM, where the query request carries query parameters indicating a request to query session management subscription data.

2. After receiving the query request, UDM reads the subscription information stored in UDR, obtains the session management subscription data from the subscription information, and returns the obtained session management subscription data to SMF.

Subscription sessions manage subscription data changes through the subscription interface. The specific steps for implementation are as follows:

1. SMF sends a subscription request to UDM to subscribe to session management subscription data.

2. After receiving the subscription request, UDM stores the SMF subscription information and returns a response.

3. If the session management subscription data changes, UDM will send a message to notify SMF, which carries the new session management subscription data.

4. SMF resends the query message to obtain the session management subscription data.

Session management subscription data is stored in UDR, and UDM supports the update and retrieval of session management subscription data:

UDM supports operators to notify UDM to update the session management subscription data stored in UDR through the BOSS interface;

Through the N10 interface, UDM supports SMF to query UDM for session management contract data stored in UDR.

When there are many 5G IoT terminals, UDR will occupy a large amount of storage resources, which will further cause slow response to user queries and subscriptions, affecting user experience.

In order to solve the problems existing in related technologies, embodiments of the present disclosure provide a contract information processing method, which can be applied in UDM;

As shown in Figure 1, the method may include the following steps:

Step 101: Obtain the query request of the terminal, and the query request includes the identification of the terminal;

Step 102: Based on the identification of the terminal, obtain the internal group identification of the terminal from the unified data repository;

Step 103: Obtain the target contract information that matches the internal group identifier from the locally stored contract information;

Step 104: Return the target subscription information and internal group identification to the terminal.

In this embodiment, the relevant data of the terminal subscription is divided into two parts for storage. One part (i.e., the internal group identification) is stored in the unified data storage database, and the remaining part (i.e., the contract information matching the internal group identification) is stored in the UDM. Since The unified data repository only saves the internal group identifier and does not need to store other data related to the contract. Therefore, compared with related technologies, all data related to the contract is stored in the UDR, which greatly reduces the storage space occupied by the UDR.

It should be understood that when obtaining the internal group identifier of the terminal from the unified database, this can be achieved by querying the mapping relationship between the preconfigured terminal identifier and the internal group identifier. In actual applications, the mapping relationship can be configured by the 5G network when the terminal signs a contract with the 5G network.

In this embodiment, when obtaining the target subscription information from the locally stored subscription information, it can be achieved by querying the mapping relationship between the preset internal group identifier and the subscription information.

In the application, in order to isolate and distinguish different locally stored subscription information, different subscription information is set to be stored in different virtual network group templates. It should be noted that the different subscription information here refers to the subscription information of different types of terminals.

Correspondingly, when the target subscription information is stored in the virtual network group template, the process of obtaining the target subscription information may be as follows:

Obtain the target virtual network group template that matches the internal group identifier from all locally stored virtual network group templates; obtain the contract information in the target virtual network group template; use the contract information in the target virtual network group template as the target contract information.

In this embodiment, the target virtual network group template matching the internal group identifier can be obtained by querying the mapping relationship between the preset internal group identifier and the virtual network group template.

In the application, since the session management data of terminals of the same type are consistent except for the internal group identifier, in order to save storage space and reduce the occupation of storage space, this embodiment configures the same virtual network group template for terminals of the same type. . Due to the same type of end The first four digits of the internal group ID on both ends are the same. Therefore, when obtaining the target virtual network group template, the sub-identifier of the internal group ID is used to obtain the target virtual network group template.

During specific implementation, in an optional embodiment, a sub-identity used to reflect template information is extracted from the internal group identification; a virtual network group template matching the sub-identity is queried from all virtual network group templates; the virtual network group template as the target virtual network group template.

In applications, the prefix sequence of the internal group identifier can be used as a sub-identifier that embodies template information. It should be understood that the preamble sequence here may be the first four digits of the internal group identifier, which is not specifically limited in this embodiment.

The protocol specifies the format of the internal group identifier as follows:

Pattern: ′^[A-Fa-f0-9]{8}-[0-9]{3}-[0-9]{2, 3}-([A-Fa-f0-9][A- Fa-f0-9]){1,10}$′.

When signing a UDM contract, the format of the internal group identifier is as follows:

^[0～9]{4}[A-Fa-f0-9]{4}-[0-9]{3}-[0-9]{2,3}-([A-Fa-f0- 9][A-Fa-f0-9]){1,10}$

Among them, the first four digits are sub-identifiers that reflect template information.

For example, the internal group identifiers of the electric lights in the park are:

00010000-460-00-01～00010000-460-00-9999

The internal logos of the robots in the park are:

00080000-460-00-01～00010000-460-00-9999

Therefore, when obtaining the contract information of the electric lights in the park, use 0001 to obtain the virtual network group template matching the electric light in order to obtain the contract information of the electric lights; and when obtaining the contract information of the robot in the park, use 0008 to obtain the virtual network group template matching the robot. Network group template to obtain the robot's contract information.

In this embodiment, in order to facilitate processing, the locally stored virtual network group templates are marked with indexes. Each virtual network group template corresponds to a unique index. Therefore, when searching for the virtual network group template matching the sub-identification, it can be implemented based on the index. .

During specific implementation, in an optional embodiment, a virtual network group template whose index matches the sub-identity is searched for from all virtual network group templates; the virtual network group template whose index matches the sub-identity is used as the virtual network group template that matches the sub-identity. Netgroup template.

In the technical solution provided by this embodiment, the query request of the terminal is obtained, and the query request packet Including the identification of the terminal; based on the identification of the terminal, obtain the internal group identification of the terminal from the unified data repository; obtain the target signing information matching the internal group identification from the locally stored signing information; return the target signing information and internal group identification to the terminal Group ID. Since only the internal group identifier is stored in the unified data repository and no other data related to the contract is stored, compared to related technologies where all data related to the contract is stored in the UDR, the storage space occupied by the UDR is greatly reduced. Moreover, in this embodiment, the subscription information of terminals of the same type is stored in the same virtual network group template, so the retrieval time can be reduced and the user's retrieval efficiency can be improved on the basis of reducing the storage space occupied by UDR.

To facilitate understanding, the signaling flow chart of the contract information processing method shown in Figure 2 is given.

In Figure 2, SMF sends an HTTP Get message to UDM, which carries query parameters and instructs the query sm-data (session management contract data); after UDM receives the query request, it sends LDAP (Lightweight Directory Access) to UDR. Protocol) request; UDM receives the LDAP response and verifies the user subscription information; UDM matches the VN Group information template according to the internal group identifier of the contract; UDM returns sm-data data to SMF, which contains VN Group information.

Based on the same disclosed concept, the embodiment of the present disclosure provides a contract information processing method, which can be applied in UDM. As shown in Figure 3, the method can include the following steps:

Step 301: Obtain the latest assigned target internal group ID of the terminal;

Step 302: Use the target internal group identifier to update the internal group identifier in the unified data repository and obtain the update result;

Step 303: If the update result indicates that the update is successful and it is determined that the target virtual network group template matching the target internal group ID is not stored locally, create a target virtual network group template to store the subscription information matching the target internal group ID.

It should be understood that when the target virtual network group template matching the target internal group identifier is stored locally, there is no need to create a target virtual network group template, and the process ends at this time.

It should be understood that the update structure indicates that the update was successful, indicating that the target internal group identification was stored in the unified data repository.

In order to save storage space and reduce storage space occupation, this embodiment configures the same virtual network group template for terminals of the same type. Since the first four digits of the internal group identifiers of terminals of the same type are the same, when determining that the target virtual network group template is stored locally, the sub-identifier of the internal group identifier is used.

During specific implementation, in an optional embodiment, a sub-identity used to reflect template information in the target internal group identification is obtained; when it is determined that all locally stored virtual network templates do not include a virtual network template matching the sub-identity, determine that the local No target virtual network group template is stored.

In this embodiment, in order to facilitate processing, the locally stored virtual network group templates are marked with an index. Each virtual network group template corresponds to a unique index. Therefore, the determination of all locally stored virtual network group templates does not include matching the sub-identifier. Virtual network templates can be implemented based on indexes.

During specific implementation, in an optional embodiment, search for a virtual network group template whose index matches the sub-identity from all virtual network group templates; when it is determined that all virtual network templates do not include a virtual network group whose index matches the sub-identity. When selecting a template, it is determined that all virtual network templates stored locally do not include a virtual network template that matches the sub-id.

In the technical solution provided by this embodiment, the latest assigned target internal group ID of the terminal is obtained; the target internal group ID is used to update the internal group ID in the unified data repository to obtain the update result; if the update result indicates that the update is successful, when it is determined When the target virtual network group template matching the target internal group ID is not stored locally, create a target virtual network group template to store the subscription information matching the target internal group ID. Since only the target internal group ID is stored in the unified data repository, and the contract information matching the target internal group ID is stored in UDM, the storage space occupied by UDR can be greatly reduced.

To facilitate understanding, a signaling flow chart of the contract information processing method shown in Figure 4 is provided.

In Figure 4, SMF sends an HTTP Post message to UDM and subscribes to sm-data; after UDM receives the subscription request, it sends an LDAP request to UDR and stores the subscription record; UDM receives an LDAP response; UDM returns a successful subscription to SMF; BOSS interface Execute command repair Change user subscription information; UDM sends an LDAP request to UDR to update user subscription data; UDM receives an LDAP response, indicating that the user subscription data has been updated successfully; UDM matches the VN Group information template table based on the internal group identifier of user subscription; UDM sends a message to SMF Subscribe to the notification message to indicate the change content of sm-data; SMF returns successfully.
