[0063] Example implementations will now be described with reference to the drawings. However, example implementations can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the inventive concept of the example implementations to those skilled in the art. The described features, structures, or characteristics can be combined in one or more implementations in any suitable manner.

[0064] In addition, the accompanying drawings are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification. The drawings illustrate examples of the present disclosure and, as such, a change in the size or proportion of some parts on the drawings should be understood as not a limitation on the scope of the present disclosure. Identical reference numerals in the drawings denote the same or similar elements throughout the several disclosed embodiments.

[0065] It should be understood that each of the steps in the method implementations of the present disclosure can be performed in a different order and / or in parallel. In addition, the method implementations can include additional steps and / or omit performing the steps shown. The scope of the present disclosure is not limited in this respect.

[0066] It should be noted that the terms "first", "second", and the like in the present disclosure are used only to distinguish different devices, modules, or units, and do not imply the order or interdependence of the functions performed by these devices, modules, or units.

[0067] It should be noted that the terms "one", "multiple", and the like in the present disclosure are illustrative and not limiting, and those skilled in the art should understand that "one or more" should be understood unless the context clearly indicates otherwise.

[0068] In order to avoid the need to subscribe to all information of the NRF when other NFs subscribe to the NRF, the technical solution of sharing information is adopted in the present disclosure, which includes the same part of multiple NF information registered in the NRF. After adopting the shared information, the NF only needs to obtain the shared information or the identifier of the shared information when registering the NRF, thereby reducing the amount of data to be transmitted for subscription. However, when the shared information in the NRF changes, the NF using the shared information does not know that the shared information has changed, thereby causing information asymmetry between the NRF and the NF, and possibly causing the information sent by each other to be misunderstood.

[0069] To solve the above problems, the present disclosure provides a subscription method, device, equipment and storage medium.

[0070] In order to describe the present disclosure in detail,Figure 1 A subscription method flow chart in the embodiments of the present disclosure is shown. It should be noted that the subscription method in the embodiments of the present disclosure is applied to the NRF.

[0071] As shown in the subscription method can include: Figure 1

[0072] S110, in the case of sharing information changing, sending a state change notification to the subscriber, the state change notification including the changed sharing information identifier and / or the changed sharing information, the subscriber including the NF and the service communication agent (Service Communication Proxy, SCP).

[0073] In some embodiments, the reason for the change of the sharing information can include:

[0074] Other access parties modify the sharing information, the network management (Operation Administration and Maintenance, OAM) modifies the sharing information, and the current NRF or other NRF modifies the sharing information.

[0075] In some embodiments, the NRF can determine in advance with the subscriber whether the subscriber contains the corresponding sharing information, and in the case of determining that the corresponding sharing information is contained, the sharing information identifier can be contained in the state change notification sent by the NRF to the subscriber.

[0076] In some embodiments, the sharing information corresponds to the sharing information identifier one by one, and the sharing information identifier can include the sharing information ID.

[0077] In some embodiments, the NF or the SCP can be individually used as the subscriber.

[0078] In some embodiments, the sharing information includes the same part of the plurality of NF information registered in the NRF.

[0079] For example, the NFs stored in the same NF Set in the NRF have the same applicable user number segment information, and these number segment information can be taken out as a sharing information.

[0080] The NF Set is a set of control plane NFs of the same type, the same service and the same slice.

[0081] The subscription method provided by the embodiments of the present disclosure can send a state change notification to the subscriber in the case of sharing information changing, so that the subscriber and the sharing information in the NRF can be kept in synchronization, and the problem of the subscription not being understood caused by the subscriber and the sharing information in the NRF being out of synchronization can be avoided. ​

[0082] Figure 2 Another subscription method flow chart in the embodiments of the present disclosure is shown. It should be noted that the subscription method in the embodiments of the present disclosure is applied to the NRF.

[0083] S210, receiving a subscription request sent by a subscriber, the subscription request comprising a shared information identifier and / or shared information.

[0084] In some embodiments, the NRF and the subscriber can belong to the same PLMN or different PLMNs.

[0085] In some embodiments, the shared information can comprise a plurality of shared information, and the shared information identifier can comprise a list comprising a plurality of shared information identifiers in the form of a table.

[0086] For example, the shared information can be Share Data, and the shared information identifier can be Share Data ID or Share Data ID List. In some embodiments, the subscription request can further comprise specific data ShareData IE of the shared information.

[0087] S220, in the case where the shared information changes, sending a state change notification to the subscriber, the state change notification comprising the changed shared information identifier and / or the changed shared information, the subscriber comprising an NF and a service communication agent SCP.

[0088] In some embodiments, the subscription method before S220 can further comprise that the NRF sends a subscription success notification to the subscriber.

[0089] In some embodiments, the subscription success notification can further comprise data SubscriptionData of the subscription success.

[0090] For example, the subscription success notification can be 201 Created.

[0091] The subscription method provided by the embodiments of the present disclosure can send a state change notification to the subscriber in the case where the shared information changes, so that the subscriber and the shared information in the NRF can be kept in synchronization, and the problem that the subscription is not understood due to the fact that the subscriber and the shared information in the NRF are not synchronized can be avoided.

[0092] Figure 3 Another subscription method flow chart in the embodiments of the present disclosure is shown. It should be noted that the subscription method in the embodiments of the present disclosure is applied to the NRF.

[0093] S310, receiving a subscription request sent by a subscriber, the subscription request comprising a shared information identifier and / or shared information.

[0094] S320, in a case where it is determined based on the subscription request that the subscription fails, sending a subscription failure message to the subscriber, the subscription failure message including at least one of redirection information, fault cause information, and internal fault information.

[0095] In some embodiments, the fault cause information includes that the OAM does not configure the shared information corresponding to the shared information identification, and the shared information corresponding to the shared information identification is not found.

[0096] In some embodiments, the fault cause information can be ProblemDetail.

[0097] For example, if the fault cause information is that the network management OAM does not configure the shared information corresponding to the shared information identification, then at this time the ProblemDetail can be SHARED_DATA_NOT_CONFIGURED.

[0098] For example, if the fault cause information is that the shared information corresponding to the shared information identification is not found, then at this time the ProblemDetail can be SHARED_DATA_ID_UNKNOWN.

[0099] For example, the redirection information can be 3XX.

[0100] In some embodiments, 4XX can be used to represent the fault cause information and the internal fault information. Among them, the fault cause information can be 400 Bad Request, and the fault cause information can include the ProblemDetails IE.

[0101] The subscription method provided by the embodiments of the present disclosure can send a state change notification to the subscriber in a case where the shared information changes, so that the subscriber and the shared information in the NRF can be kept synchronized, and the problem that the subscription is not understood due to the fact that the subscriber and the shared information in the NRF are not synchronized is avoided.

[0105] In some embodiments, when the subscriber receives a status change notification, the subscriber synchronizes the locally stored shared information based on the changed shared information identifier and / or the changed shared information contained in the status change notification.

[0106] In some embodiments, when synchronizing locally stored shared information, there may be two results: synchronization failure and synchronization success.

[0107] In some embodiments, regardless of whether the synchronization succeeds or fails, the subscriber will send a synchronization response to the NRF, and the synchronization response includes a synchronization failure message.

[0108] For example, if the synchronization is successful, the subscriber can send 204 No content to the NRF. If the synchronization failure message is that the shared information does not exist locally, the subscriber can send 404 Not Found to the NRF with ProblemDetails. If the synchronization failure message is a redirection message, the subscriber can send "3XX" to the NRF. If the synchronization failure message is an internal fault message, the subscriber can send "5XX" to the NRF.

[0109] The subscription method provided by the embodiment of the present disclosure sends a status change notification to the subscriber when the shared information changes, so that the subscriber can keep the shared information in the NRF synchronized, avoiding the problem of misunderstanding of the subscription caused by the subscriber and the shared information in the NRF being out of sync.
