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 those 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 exemplary only and not as 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.
A 5G SA (Stand Alone) core network may configure a DNN (e.g., ctnet) of a data service subscribed to by a general user in a UDM network element; when the AMF entity acquires the subscription data of the user from the UDM entity, DNN in the subscription data of the user can be acquired; in the session creating process, an AMF entity sends an Nsmf _ PDUSessionCreateSMContext request to an SMF entity and sends the DNN to the SMF entity; the SMF entity randomly allocates a user address to the user in a pre-configured address pool according to the DNN of the user carried in the request; the terminal will use the address for service access when using data services.
As mentioned above, most of the ordinary users of the same operator use the same data service DNN for session creation and use of the data service. In the internet, only the source IP address or the destination IP address in the data message represents user information such as user operator information, mobile user or broadband user information, and access location. This results in that different grades of mobile users under the same operator cannot be distinguished, and thus, hierarchical service guarantee and hierarchical service exclusive sharing cannot be performed on users of different grades.
In order to solve the technical problem, the present disclosure adds a subscription attribute on a user level in a UDM network element of a 5GC (core network); after obtaining the user level, the AMF entity sends the user level and the user signed DNN together to the SMF entity in a session establishing request; the SMF entity distributes a user IPv6(Internet Protocol Version 6, 6 th edition) address of a corresponding network segment to the user according to the signed DNN in an address pool corresponding to the user level, and realizes that the user who subscribes different services signs different user levels.
Therefore, when the user uses the service, the user grade can be distinguished in the Internet through the source IP address or the destination IP address, so that the development of differentiated service and service is realized.
For example, the technical solution of the present disclosure can be realized by the following embodiments.
Fig. 1 illustrates a flow diagram of some embodiments of a user address assignment method of the present disclosure.
As shown in fig. 1, in step 110, subscription data of a user performing a user attachment is acquired. The subscription data includes the DNN and the user class of the user.
In some embodiments, subscription data is obtained from a UDM entity by the AMF entity sending a Nudm sdm message to the UDM entity; and sending an Nsmf _ PDUSession _ CreateSMContext request carrying the subscription data to an SMF entity through an AMF entity.
In some embodiments, in the user attachment process, the AMF entity sends a numm _ sdm message to the UDM entity to obtain subscription data of the user; the UDM entity returns the information containing the data DNN signed by the user and the signing attributes such as the user level to the AMF entity; in the process of creating the session, the AMF entity carries the information of the session DNN and the user level of the user in the Nsmf _ pdusesion _ CreateSMContext request and sends the request to the SMF entity.
For example, the AMF entity receives a registration request of a user, and obtains user subscription data of the user from the UDM entity; the user subscription data returned by the UDM entity includes DNN ctnet, user level service-guarantee2, and other subscription data for the user.
For example, the AMF entity transmits an Nsmf pdusessioncreatesmcontext message to the SMF entity requesting the creation of a session. The message carries the user's imsi:460111000010000, DNN ctnet, user level service-guarantee 2.
In step 120, an address for accessing the data service is allocated to the user according to the DNN and the user level, so that the internet performs service provisioning corresponding to the user level for the user according to the address information of the user in the data message.
In some embodiments, address pools containing different network segments are configured by the SMF entity for different user classes under the same DNN.
For example, the SMF entity configures the IPv6 address pool of the user public network containing different network segments for different user classes under the same DNN.
For example, the SMF entity configures the user IPv6 address pools of different network segments for different user classes for data whose DNN is ctnet: the user level is service-guarantee1, and the corresponding user IPv6 public network address pool is 240e:0180:0000: 40; the user level is service-guarantee2, and the corresponding user IPv6 public network address pool is 240e:0180:0001:: 40; the user level is exclusive-service1, and the corresponding user IPv6 public network address pool is 240e:0180:0005: 40; the user level is exclusive-service2, and the corresponding user IPv6 public network address pool is 240e:0180:0006: 40.
In some embodiments, in the event of a change in the user level of the user, a request to add or modify the user level of the user is sent by the CRM system to the UDM network element to add or modify the user level of the user in the UDM.
For example, after accepting a task of adding or modifying a user level, the front-end department sends a request for adding or modifying a user level subscription attribute to the UDM network element of the 5G core network through the CRM system. For example, the user-level subscription profile is identified in the form of at least one of a string or an integer.
For example, after receiving the front-end service acceptance, the CRM system sends to the UDM entity a new service-guard 2 user-level subscription attribute for a user whose IMSI (International Mobile Subscriber identity) is 460111000010000.
Therefore, when the user can add or modify the user level subscription attribute without replacing hardware such as an SIM (Subscriber Identity Module) card and the like, the method is beneficial to the user to use and experience the service quickly and improves the user experience.
In some embodiments, one address field may be selected to be allocated to the user in a pre-configured address pool corresponding to the DNN and the user level. For example, acquiring subscription data of a user from a UDM entity through an AMF entity; assigning an address for accessing data traffic to a user comprises: and allocating an address for accessing the data service for the user by the SMF entity according to the subscription data sent by the AMF entity.
For example, the SMF entity allocates an address for accessing a data service to the user according to the subscription data in the Nsmf _ pdusesion _ CreateSMContext request.
For example, after receiving a request from the AMF entity, the SMF entity obtains a session DNN and user level information in the request; the SMF entity selects one IPv6 address field from the address pool corresponding to the session DNN and the user level as the user IP address and returns the user IP address to the AMF entity.
For example, the SMF entity selects one address field 240e:0180:0001: 0010:/64 from the 240e:0180: 0001:/40 address pool as the user's public network IPv6 address field according to the DNN and the user level in the request, and returns the address field to the AMF entity.
In some embodiments, information related to the allocated address is sent to the terminal of the user through the AMF entity, so that the terminal performs access to the data service according to the related information.
For example, the AMF entity sends the received allocated IPv6 address field to the terminal; the terminal uses an address in the IPv6 address field to access data traffic.
For example, the AMF entity issues the address field to the UE (user equipment); the UE selects one address 240e:0180:0001:0010:000F:000F:000F in the address terminal as the access public network address.
Fig. 2 shows a flow diagram of further embodiments of a method of assigning user addresses of the present disclosure.
As shown in fig. 2, in step 210, the user rank of the user is determined according to the address information of the user in the data message.
In some embodiments, an address segment in which at least one of a source address or a destination address is located in a data packet is determined; and determining the user grade according to the address field.
In step 220, according to the user level, service provisioning corresponding to the user level is performed on the user.
In some embodiments, in the internet, service provisioning at a corresponding user level may be performed on a data packet with a source address or a destination address in a corresponding address field. Therefore, the accurate guarantee of the user data service is realized on the premise that the public network has no user information.
In the above embodiment, the SMF entity can identify the user level of the user by adding the user level subscription attribute to the UDM entity; and the user IP addresses of the corresponding network segments can be distributed according to the user grade signing attribute.
Thereby, it is possible to realize: allocating IP addresses of different network segments for users of different grades, and identifying the grade of the user sent by the data message in the public network according to the source address or the destination IP address in the message by the user grade information carried by the data message; different grades of differentiated hierarchical service guarantee and hierarchical service exclusive sharing are adopted for different users in the public network.
Fig. 3a, 3b show signaling diagrams of some embodiments of the allocation method of user addresses of the present disclosure.
As shown in fig. 3a and 3b, in event 1, the SMF entity configures the user IPv6 address pools of different network segments for different user classes for the data whose DNN is ctnet.
For example, the user level is service-guarantee1, and the corresponding user IPv6 public network address pool is 240e:0180: 0000:/40; the user level is service-guarantee2, and the corresponding user IPv6 public network address pool is 240e:0180:0001: 40; the user level is exclusive-service1, and the corresponding user IPv6 public network address pool is 240e:0180:0005: 40; the user level is exclusive-service2, and the corresponding user IPv6 public network address pool is 240e:0180:0006: 40.
In event 2, after receiving the front-end service acceptance, the CRM system sends the front-end service acceptance to the UDM entity, and adds a user-level subscription attribute of service-guard 2 for a user with IMSI 460111000010000.
In event 3, the AMF entity receives a registration request of a user, and acquires user subscription data of the user from the UDM entity; the user subscription data returned by the UDM entity includes DNN ctnet, user level service-guarantee2, and other subscription data for the user.
At event 4, the AMF entity sends an Nsmf _ pdusesion _ CreateSMContext message to the SMF entity requesting the creation of a session. The message carries the user's imsi:460111000010000, DNN ctnet, user level service-guarantee 2.
In event 5, the SMF entity selects an address field 240e:0180:0001:0010: 64 from the 240e:0180:0001: 40 address pool as the user's public network IPv6 address field based on the DNN in the request and the user level, and returns the address field to the AMF entity.
At event 6, the AMF entity issues the address field to the UE.
In event 7, the UE selects one address 240e:0180:0001:0010:000F:000F:000F:000F in the address realm as the access public network address.
In the event 8, in the internet, service guarantee of the corresponding user level can be performed on the data message of the source address or the destination address in the corresponding address field. Therefore, the accurate guarantee of the user data service is realized on the premise that the public network has no user information.
