Fig. 1 is a flow diagram of some embodiments of a private network slicing access method of the present disclosure.
In step 110, the public network NSSF network element receives a query target AMF request sent by the public network AMF network element.
In some embodiments, the public network AMF network element sends a query target AMF request to the public network NSSF network element in case the user slice cannot be supported.
In step 120, if the target AMF is not queried by the NSSF network element of the public network, returning default AMF setting information to the AMF network element of the public network.
In some embodiments, the NSSF network element of the public network configures default AMF Set (setup) information, where the default AMF Set information includes an AMF Set identifier.
In some embodiments, the default AMF Set information also includes AMF address information, such as an AMF IP address.
For the AMF Set information, slice information supported by the AMF Set information does not need to be configured.
In some embodiments, the AMF Set corresponds to a private network gateway, rather than a real AMF network element. The AMF IP address information is the IP address of the private network gateway.
In step 130, the public network AMF network element redirects the user registration message to a private network gateway according to the AMF setting information, wherein the private network gateway is configured to guide the user to access the private network slice.
In some embodiments, the private gateway redirects the user to the appropriate private network AMF according to preconfigured information.
In the above embodiment, the public network NSSF returns the default AMF Set information when the appropriate AMF cannot be found for the user, the public network AMF redirects the user registration message to the private network gateway, and the private network gateway selectively redirects the user registration message to the appropriate private network AMF, so that the influence of frequent change of the private network slicing service on the public network can be avoided, and the stable operation of the public network is ensured.
Fig. 2 is a flow chart illustrating further embodiments of the private network slicing access method of the present disclosure.
In step 210, the NSSF network element of the public network configures default AMF Set information.
In some embodiments, since the number of the public network AMF network elements is much greater than that of the public network NSSF network elements, if corresponding default AMF Set information is configured in each public network AMF network element, the change of the public network AMF network element is large. Therefore, compared with the configuration of the default AMF Set information for the public network AMF network element, the configuration of the default AMF Set information for the public network NSSF network element has less influence on the public network.
In step 220, the public network AMF network element sends a request for querying the target AMF to the public network NSSF network element.
In some embodiments, after receiving a registration message sent by a user, a public network AMF network element performs terminal authentication, and then queries a UDM (Unified Data Management) for subscription section information of the user. And if the signed slice of the user does not exist in the slice range supported by the public network AMF network element, the public network AMF network element does not support the slice of the user, and a network slice query request is sent to the public network NSSF network element to query the target AMF.
In step 230, the NSSF determines whether an AMF suitable for providing service to the user can be found, if so, step 270 is performed, otherwise, step 240 is performed.
In step 240, the NSSF network element of the public network returns default AMF Set information to the AMF network element of the public network.
In some embodiments, the public network NSSF network element returns default AMF Set information to the public network AMF network element if a suitable AMF cannot be found to provide a service for the user according to the slice information signed by the user and the slice information requested by the user.
In step 250, the public network AMF network element redirects the user to the private network gateway according to the received default AMF Set information.
In some embodiments, if only the AMF Set identifier is included in the AMF Set information, the public Network AMF Network element further needs to query and acquire specific AMF address information corresponding to the AMF Set in an NRF (Network redundancy Function) Network element according to the AMF Set identifier; if the AMF Set information already contains the corresponding AMF address information, the public network AMF network element may directly initiate a redirection procedure.
The private network gateway directs the user to access the appropriate private network slice at step 260.
In some embodiments, the private Network element redirects the user to an appropriate private Network AMF element according to a pre-configured correspondence between the slice identifier, the DNN (Data Network Name), and the private Network AMF.
In some embodiments, the private network gateway receives a user registration request redirection message, which includes information such as slice identifier, DNN, etc.
In some embodiments, after receiving the user registration request redirection message, the private network gateway sends an authentication query to the public network AMF, and receives a security context corresponding to the user registration request redirection message returned by the public network AMF, so as to avoid performing a re-authentication operation.
In step 270, access is performed according to the normal procedure.
Because there are many private network AMF network elements, if a public network AMF network element directly searches for a private network AMF network element, it is necessary to frequently perform data configuration on a public network NSSF network element. In the embodiment, the public network AMF network element does not need to sense the private network AMF network element, and the user is redirected to the private network gateway according to the received default AMF Set information, so that the influence on the public network caused by frequent change of the private network slicing service can be avoided. In addition, because the communication between the public network element and the private network element needs to pass through the private network gateway, and the private network gateway can safely isolate the communication between the public network element and the private network element, the safety risk of direct interconnection of the public network AMF and the private network AMF in a non-safety domain is avoided.
Fig. 3 is a flow chart illustrating further embodiments of the private network slicing access method of the present disclosure.
In step 310, the NSSF network element of the public network configures default AMF Set information.
In step 320, the terminal initiates a registration request to the AMF Network element of the public Network, optionally carrying a request NSSAI (Network Slice Selection Assistance Information).
At step 330, authentication of the user is completed.
The terminal cooperates with the public network AMF network element and the AUSF (Authentication Server Function) network element to complete the Authentication of the user.
In step 340, the public network AMF network element queries the UDM network element to obtain the slice information signed by the user.
In step 350, the public network AMF network element sends a slice selection request to the public network NSSF network element, where the request carries the NSSAI and location information signed by the user, and may also carry the NSSAI of the request.
And if the user does not have the NSSAI for reporting the request, the public network AMF network element uses the default NSSAI signed by the user.
In step 360, the public network NSSF network element cannot find a suitable AMF network element for the user according to the information such as the request NSSAI, the subscribed NSSAI, and the location.
In step 370, the NSSF network element of the public network returns a slice selection response to the AMF network element of the public network, where the slice selection response carries default AMF Set information.
In step 380, the public network AMF network element redirects the registration request to the private network gateway according to the AMF Set information.
The private network gateway redirects the registration request to the appropriate private network AMF again, step 390.
In step 3100, the terminal accesses the private network AMF and completes a subsequent registration procedure.
After receiving the registration request in the redirection message, the private network AMF network element completes the subsequent user registration process, so that the user successfully accesses the appropriate 5G private network.
In the above embodiment, the public network NSSF returns the default AMF Set information when the appropriate AMF cannot be found for the user, the public network AMF redirects the user registration message to the private network gateway, and the private network gateway selectively redirects the user registration message to the appropriate private network AMF, thereby avoiding the influence of frequent change of the private network slicing service on the public network AMF.
Fig. 4 is a schematic structural diagram of some embodiments of a private network slice access apparatus of the present disclosure. The device comprises a public network NSSF network element 410 and a public network AMF network element 420.
The public network NSSF network element 410 is configured to receive a query target AMF request sent by the public network AMF network element 420, and if the target AMF is not queried, default AMF setting information is returned to the public network AMF network element; the public network AMF network element 420 is configured to redirect the user registration message to a private network gateway according to the AMF setting information, wherein the private network gateway is configured to guide the user to access the private network slice.
In some embodiments, the public network AMF network element 420 sends a query target AMF request to the public network NSSF network element 410 in case the user slice cannot be supported. And the public network NSSF network element 410 returns default AMF Set information to the public network AMF network element 420 if a proper AMF cannot be found to provide service for the user according to the slice information signed by the user and the slice information requested by the user.
In some embodiments, the NSSF network element of the public network configures default AMF Set information, where the default AMF Set information includes an AMF Set identifier.
In some embodiments, the default AMF Set information also includes AMF address information, such as an AMF IP address.
In some embodiments, if only the AMF Set identifier is included in the AMF Set information, the public network AMF network element 420 further needs to query and obtain specific AMF address information corresponding to the AMF Set in the NRF network element according to the AMF Set identifier; if the AMF Set information already contains the corresponding AMF address information, the public network AMF network element 420 may directly initiate a redirection procedure.
In some embodiments, the private gateway redirects the user to the appropriate private network AMF according to preconfigured information. For example, the user is redirected to a suitable private network AMF network element according to the pre-configured slice identifier and the corresponding relationship between the DNN and the private network AMF.
In the above embodiment, the public network NSSF returns the default AMF Set information when the appropriate AMF cannot be found for the user, the public network AMF redirects the user registration message to the private network gateway, and the private network gateway selectively redirects the user registration message to the appropriate private network AMF, so that the influence of frequent change of the private network slicing service on the public network can be avoided.
In other embodiments of the present disclosure, a private network slice access system is further protected, where the system includes a public network NSSF network element and a public network AMF network element in the foregoing apparatus, and further includes a private network element configured to guide a user to access a private network slice.
Because the communication between the public network element and the private network element needs to pass through the private network gateway, and the private network gateway can safely isolate the communication between the public network element and the private network element, the safety risk of direct interconnection of the public network AMF and the private network AMF in a non-safety domain is avoided.
