Detailed Description
The present application will be described with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
In the prior art, if an authorized PLMN is carried by an NF provider when registering with an NRF, all slices under the authorized PLMN are carried at the same time, while the NF provider may only expect to authorize a certain type of NF or a part of slices under a certain PLMN, and in this case, precise authorization cannot be achieved. Taking authorized PLMN and authorized slice as an example, the NF provider expects that the NF consumer in which slice 1 under authorized PLMN1 and slice 2 under PLMN2 are located can find itself through NRF, but if the NF provider registers with NRF, if carrying authorized PLMN1 and authorized PLMN2, and simultaneously carrying authorized slice 1 and authorized slice 2, in this case, the NF consumer in which slice 2 under PLMN1 is located can also find itself to the NF provider through NRF. The present embodiment provides a network function management method for the situations of low authorization precision and poor reliability of network function services, and determines whether to authorize the NF consumer to find the NF provider according to a specific authorization item by comparing the attribution information of the NF consumer with the registration information of the NF provider, thereby implementing accurate authorization and improving the reliability of network function services.
Fig. 1 is a flowchart of a network function management method according to an embodiment. The method may be applied to a management network element, which may be the NRF described above. As shown in fig. 1, the method provided in this embodiment includes steps 110 and 130.
In step 110, registration information of a first network element is received, where the registration information includes location information and an authorization item of the first network element.
In step 120, an authorization request of a second network element is received, where the authorization request includes attribution information of the second network element.
In step 130, the location information is fed back to the second network element according to the attribution information and the authorization item.
In this embodiment, the first network element is an NF provider, and the second network element is an NF consumer. The authorization items may include authorized PLMNs and authorized slices or slice lists. When registering with a management network element, the first network element can configure a specific authorization policy by carrying a specific authorization item according to actual comprehensive networking configuration of an operator, wherein the authorization item can represent that only a part of slices corresponding to a PLMN is allowed to be authorized, and other slices under the same PLMN cannot be authorized, so that accurate cross authorization and accurate control of network functions are realized. For example, a first network element, upon registering with a managing network element, authorizes a second network element having a PLMN of 46011 and a corresponding slice of 1-111111, a PLMN of 46012, and a slice of 2-222222 to discover itself through the managing network element. Accordingly, when the second network element sends an authorization request (request for finding the first network element) to the management network element, the second network element provides its own home information to the management network element.
In an embodiment, feeding back the location information to the second network element according to the home information and the authorization item includes: and under the condition that the attribution information is matched with the authorization item, feeding back the position information to the second network element, otherwise, feeding back a response message of failure discovery to the second network element.
In this embodiment, the matching between the attribution information and the authorization items means that each item in the attribution information is consistent with each authorization item. For example, the second network element is used as an NF consumer, the PLMN to which the second network element belongs is 46011, and the corresponding slice is 1 to 111111, and if the management network element determines that the matching (or authentication) between the attribution information and the authorization item is successful, the second network element is authorized to discover the first network element, and the location information of the first network element is returned to the second network element; if the PLMN to which the second network element belongs is 46011 and the corresponding slice is 2-222222, the management network element determines that the matching (or authentication) is failed, and cannot authorize the second network element, and the second network element cannot find the first network element through the management network element.
In one embodiment, the authorization item includes: an authorized PLMN and an authorized Network Slice Selection Assistance Information (NSSAI) list, the Network Slice Selection Assistance Information NSSAI list including at least one NSSAI.
In this embodiment, the authorization item includes a PLMN and NSSAI list, where the NSSAI list includes at least one NSSAI, and the NSSAI is used to indicate an authorized slice. For example, the first network element, when registering with the managing network element, may provide the PLMNs and the at least one NSSAI that it is allowed to authorize. One PLMN may correspond to multiple NSSAIs, and the second network element may not only satisfy the PLMN but also satisfy the NSSAI under the PLMN to obtain authorization, otherwise the first network element may not be discovered through the management network element.
Fig. 2 is a diagram illustrating an example of an application of a network function management process in an embodiment. In this embodiment, the registration information includes location information and authorization items, and the authorization items include PLMN and NSSAI. As shown in fig. 2, NF-A, NF-B, NF-C is a second network element (NF consumer), NF-D is a first network element (NF provider), NRF is a Management network element, NF-a is exemplified by an Access and Mobility Management Function (AMF), NF-B is exemplified by a Session Management Function (SMF), NF-C is exemplified by an Authentication Server Function (AUSF), and NF-D is exemplified by a Unified Data Management (UDM).
The specific implementation process is as follows:
step 301: NF-D registers to NRF, the registration information carries position information and authorization items, the authorized PLMN is 46011 and the corresponding authorization slice is 1-111111; the authorized PLMN is 46012 and the corresponding authorization slice is 2-222222.
Step 302: the NF-D is successfully registered in the NRF, the NRF replies a response message of successful registration to the NF-D, and the position information, PLMN and NSSAI of the NF-D are saved.
Step 303: the NF-A sends a request (authorization request) for discovering NF-D to NRF, wherein the request carries home information of the NF-D, the PLMN to which the NF-A belongs is 46011, and the corresponding slice is 1-111111.
Step 304: the NRF determines whether to authorize according to the attribution information and the authorization item, specifically, determines whether the PLMN and the slice to which the NF-a belongs are consistent with the PLMN and the NSSAI stored in step 302. In this case, the NRF returns the location information of the NF-D to the NF-a through the authorization message.
Step 305: the NF-B sends a request (authorization request) for discovering NF-D to the NRF, wherein the request carries home information of the NF-D, the PLMN to which the NF-A belongs is 46011, and the corresponding slice is 2-222222.
Step 306: the NRF determines whether to authorize according to the attribution information and the authorization item, specifically, determines whether the PLMN and the slice to which the NF-B belongs are consistent with the PLMN and the NSSAI stored in step 302. In this case, if the NF-B is inconsistent, that is, the slice to which the NF-B belongs is not within the authorized slice range, the NRF determines that the NF-B is not within the authorized range of the NF-D, returns a response message indicating that the NF-B fails to find the NF-B, and does not return the location information of the NF-D to the NF-B.
Step 307: the NF-C sends a request (authorization request) for discovering NF-D to NRF, wherein the request carries home information of the NF-D, the PLMN to which the NF-A belongs is 46012, and the slice is 2-222222.
Step 308: the NRF determines whether to authorize according to the attribution information and the authorization item, specifically, determines whether the PLMN and the slice to which the NF-C belongs are consistent with the PLMN and the NSSAI stored in step 302. In this case, the NRF returns the location information of the NF-D to the NF-C through the authorization message.
In this embodiment, the home information and each authorization item need to be completely matched, for example, slice 2-222222 with PLMN 46011 is not authorized, so as to implement accurate cross authorization according to PLMN and NSSAI.
Fig. 3 is a schematic diagram of an application example of a network function management process in another embodiment. In this embodiment, the registration information includes location information and an authorization item, where the authorization item includes a PLMN and an NSSAI list, and an NSSAI list includes two NSSAIs as an example. As shown in FIG. 3, NF-A, NF-B, NF-C is the second network element (NF consumer), NF-D is the first network element (NF provider), NRF is the management network element, NF-A may be AMF, NF-B may be SMF, NF-C may be AUSF, and NF-D may be UDM. The specific implementation process is as follows:
step 401: NF-D registers to NRF, the registration information carries position information and authorization items, the authorized PLMN is 46011 and the corresponding authorization slices are 1-111111 and 1-222222; the authorized PLMN is 46012 and the corresponding authorization slices are 2-222222 and 3-333333.
Step 402: the NF-D successfully registers in the NRF, the NRF replies a registration success response message to the NF-D, and the position information, PLMN and NSSAI list of the NF-D are saved.
Step 403: the NF-A sends a request (authorization request) for discovering NF-D to NRF, wherein the request carries home information of the NF-D, the PLMN to which the NF-A belongs is 46011, and the corresponding slice is 1-222222.
Step 404: the NRF determines whether to authorize according to the attribution information and the authorization item, specifically, determines whether the PLMN and the slice to which the NF-a belongs are consistent with the PLMN and the NSSAI list stored in step 402. In this example, if the NF-a slice is within the authorized slice list, the NRF returns the location information of the NF-D to the NF-a via the authorization message.
Step 405: the NF-B sends a request (authorization request) for discovering NF-D to NRF, wherein the request carries home information of the NF-D, the PLMN to which the NF-A belongs is 46012, and the corresponding slice is 1-111111.
Step 406: the NRF determines whether to authorize according to the attribution information and the authorization item, specifically, determines whether the PLMN and the slice to which the NF-B belongs are consistent with the PLMN and the NSSAI list stored in step 402. In this example, if the NF-B is inconsistent, that is, the slice to which the NF-B belongs is not within the authorized slice list, the NRF determines that the NF-B is not within the authorized range of the NF-D, and returns a response message indicating that the discovery is failed to the NF-B, and does not return the location information of the NF-D to the NF-B.
Step 407: the NF-C sends a request (authorization request) for discovering NF-D to NRF, wherein the request carries home information of the NF-D, the PLMN to which the NF-A belongs is 46012, and the corresponding slice is 3-333333.
Step 408: the NRF determines whether to authorize according to the attribution information and the authorization item, specifically, determines whether the PLMN and the slice to which the NF-C belongs are consistent with the PLMN and the NSSAI stored in step 302. In this case, the NRF returns the location information of the NF-D to the NF-C through the authorization message.
According to the network function management method, the slice list under the PLMN is authorized clearly by adding the authorization item, fine management is achieved based on a more accurate authorization strategy, a plurality of NF providers can be provided, each NF provider authorizes different slices under different PLMNs, division of labor is clear, and service processing efficiency and adaptive capacity of network functions are improved.
