Detailed Description
Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.
Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.
Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As mentioned above, the 3rd Generation Partnership Project (3rd Generation Partnership Project) organization defines a unified user database. That is, the capability openness platform NEF entity, the policy network element PCF entity, and the user database UDM (Unified Data Management) entity share the same Data store.
However, the data of the NEF, PCF, and UDM have no commonality, and there is a different definition in UDR. Therefore, it is not necessary to set the three databases as a unified database. In addition, the data is insecure due to the way of storing the data together. For example, important subscription data may be exposed. Moreover, this way of co-data storage increases the amount of interaction for UDRs, and also increases unnecessary routing roundabouts.
In view of the above technical problem, the present disclosure configures the interface of the NEF and the UDR as an internal interface, and integrates both physically and logically. Therefore, effective isolation of different data can be realized, and the safety is improved; meanwhile, data are stored or acquired locally, and excessive network interaction can be avoided, so that service delay is reduced, and user experience is improved. This can be achieved, for example, by the following embodiments.
Fig. 1 shows a flow diagram of some embodiments of a method of processing a service request of the present disclosure.
As shown in fig. 1, the method includes: step 110, mapping the service request; and a step 120 of sending the mapping result through the own UDR.
In step 110, in response to receiving the service request from the third party application, the NEF entity maps the service request to a corresponding network request.
In some embodiments, the NEF entity accesses its own equipped UDR through its internal interface, obtaining data related to the service request; the NEF entity maps the service request to a network request according to the relevant data. For example, a service request is to access a network at a location; the NEF entity obtains the relevant data of the service request through an independent UDR of the NEF entity, and therefore the service request is mapped into a network request which can be identified by a network side.
In step 120, the NEF entity sends the network request to the policy control function PCF entity via its own provisioned UDR. The PCF entity obtains a corresponding strategy according to the network request and is used for processing the service request.
In some embodiments, the respective policy is for the PCF entity to access its own provisioned UDR acquisition through its internal interface. For example, the PCF entity determines the change of the third party application by its own equipped UDR upon network request; the PCF entity obtains the relevant policy through the UDR equipped by the PCF entity according to the change of the third party application.
In some embodiments, the corresponding policy is sent by the PCF entity to the SMF entity for execution to handle the service request.
In the above embodiments, the NEF entity is provided with a dedicated UDR, and the NEF entity and its UDR are physically and logically integrated. Therefore, other network elements cannot access the special UDR, and the safety of system data is improved.
Fig. 2 shows a schematic diagram of some embodiments of a service request processing device of the present disclosure.
As shown in fig. 2, the service request processing device may be an open capability platform. The capability opening platform comprises a NEF entity at the front end of the platform and a special UDR specially configured for the NEF entity at the rear end of the platform.
The NEF entity accesses its private UDR through an internal interface. The UDR may store service related data, such as Structure data for exposure (Structure data), Application data (Application data), and the like.
In the above embodiment, the UDR of the capability openness platform is independent and is used as a storage center for the back-end capability openness response data of the NEF entity. Therefore, isolation on storage of other data (such as PCF, UDM and the like) is not required to be specially configured, and the security of the UDM subscription data and the PCF policy data can be ensured.
Moreover, because the NEF entity is integrated with the UDR, routing roundabout is not needed for interaction of the NEF entity and the UDR, time delay is reduced, and user experience is improved; in addition, the commercial process with open capability can be promoted, and the standardization of the UDR interface and the development progress of a manufacturer are not required.
Fig. 3 shows a signaling diagram of some embodiments of a method of processing a service request of the present disclosure.
As shown in fig. 3, the PCF entity (or policy network element) and the NEF entity of the capability opening platform are respectively equipped with independent UDRs.
At event 310, the third party application platform creates a service request (e.g., a traffic steering request, etc.) and sends the service request to the NEF entity.
In event 320, the NEF entity maps the service request to a network request and sends it to the PCF entity (or policy network element) via a separate UDR provisioned for itself.
In event 330, the PCF entity replies with a receive response to the NEF entity.
At event 340, the NEF entity replies to the third party application platform with a receive response.
In event 350, the PCF entity sends a service request corresponding policy to the SMF entity via its own equipped independent UDR. For example, the PCF entity determines the change of the third party application platform service request according to the network request, through its own equipped independent UDR; the PCF entity determines a new policy for the service request based on the change.
At event 360, the SMF entity replies with a receive response to the PCF entity.
At event 370, the SMF entity enforces the corresponding policy for the third party application.
In the above embodiment, a technical scheme that the capability open platform adopts an independent database is provided for the problem of current user data independence. That is, the front end of the capability open platform communicates with an AF (Application Function) entity and each network element of 4G or 5G through a standardized interface; and an internal interface is adopted to communicate with the UDR, so that the operations of quickly acquiring, storing, updating and the like of the capacity open data are realized.
Therefore, the security of the user subscription data is ensured, the service processing time delay is reduced, and the service experience is improved. Moreover, the network deployment with open capability can be simplified, and the development process with open capability is promoted.

As shown in fig. 4, the processing device 4 of the service request comprises a mapping unit 41 and a sending unit 42. For example, the processing means 4 may be provided at the NEF entity.
The mapping unit 41 maps the service request to a corresponding network request in response to receiving the service request from the third party application.
The sending unit 42 sends the network request to the PCF entity through the UDR provided by the NEF entity itself, so that the PCF entity obtains a corresponding policy according to the network request for processing the service request.
In some embodiments, the mapping unit 41 accesses the UDR provided by the NEF entity itself through the internal interface of the NEF entity to obtain the relevant data of the service request; and mapping the service request into a network request according to the related data.
In some embodiments, the respective policy is for the PCF entity to access its own provisioned UDR acquisition through its internal interface. For example, the corresponding policy is obtained by: the PCF entity determines the change of the third party application through the UDR equipped by the PCF entity according to the network request; the PCF entity obtains the relevant policy through the UDR equipped by the PCF entity according to the change of the third party application.
In some embodiments, the corresponding policy is sent by the PCF entity to the SMF entity for execution to handle the service request.
In the above embodiments, the NEF entity is provided with a dedicated UDR, and the NEF entity and its UDR are physically and logically integrated. Therefore, other network elements cannot access the special UDR, and the safety of system data is improved.
