Description

Subscription data configuration method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring subscription data.

Background

The non-public network (NPN) is a non-public deployed fifth-generation mobile communication system (5th Generation,5G) network, and the NPN may be implemented by a network function of the public land mobile network (public land mobi le network, PLMN) or may be implemented by a network function independent of the PLMN. When the NPN is implemented in dependence of network functions of the PLMN, the NPN may be implemented using network slices in the PLMN, while a closed access group (closed access group, CAG) function may be selected for use in order to prevent unauthorized User Equipment (UE) from attempting to access the NPN. The CAG identifies a set of UEs that allow access to cells associated with the CAG (or simply CAG cells). When the NPN is deployed independently (i.e., independent of the PLMN), the NPN is identified using a PLMN identification (identifier) +network identification (network identifier, NID). In the independently deployed NPN, the cell broadcasts PLMN ID+NID, and the UE selects to attempt to access the NPN network according to the broadcast information and the configured network selection information. The NPN needs to support online account opening of the UE, where online account opening of the UE refers to configuring, by the UE through the 5G network, subscription data of the UE at a target NPN (i.e., an NPN attempting to access) when the UE is initially started. However, the subscription data of the UE at the target NPN may be configured through a Control Plane (CP) or may be configured through a User Plane (UP), and different configurations may also have different requirements for the UE, the login network (onboarding network, ON), and the subscription network (e.g., subscription owner (subscription owner, SO)). Therefore, how to select the configuration mode of the subscription data of the UE on the target NPN and configure the subscription data for the UE based on the selected configuration mode when the UE opens an account online is one of the technical problems to be solved currently.

Detailed Description

Third generation partnership project (3) ^rd generation partnership proiect,3 GPP) standard-established 5G communication system architecture is composed of four components including a terminal, AN Access Network (AN), a Core network (Core), and a Data Network (DN). Next gen (or NG) is a next generation (or 5G) mobile communication system architecture. Referring to fig. 1, fig. 1 is a schematic diagram of an architecture of a 5G communication system. In the communication system architecture shown in fig. 1, the terminal, the access network and the core network are main components forming the communication system architecture, and can be logically divided into two parts, namely a user plane and a control plane, wherein the control plane is responsible for the management of the mobile network, and the user plane is responsible for the transmission of service data. In fig. 1, the NG2 reference point is located between the control plane of the access network and the control plane of the core network, the NG3 reference point is located between the user plane of the access network and the user plane of the core network, and the NG6 reference point is located between the user plane of the core network and the data network. The data network is mainly used for providing business services for the terminal, and the client is generally located at the terminal, and the server is located at the data network. The data network may be a private network, such as a local area network, or an external network not under the control of the operator (i.e. public data network (public data network, PDN) network), such as the Internet (Internet), or a proprietary network co-deployed by the operator, such as a network providing Internet protocol (Internet protocol, IP) multimedia network subsystem (IP multimedia core network subsystem, IMS) services. For ease of understanding, the following will illustrate an infrastructure of a communication system architecture constituted by a terminal, an access network device in an access network, and a core network device in a core network.

Referring to fig. 2, fig. 2 is an infrastructure of a 5G communication system according to the present application. The communication system 100 provided by the present application may include a core network device 110, an access network device 120, and a terminal 130.

For convenience of description, in the following description of the present application, the above-mentioned various terminals will be described by taking UE as an example. The NextGen UE will use the new air interface technology to establish signal and data connections with access network devices in the access network to transmit control signals and traffic data to the mobile network.

The access network devices (such as the access network device 121 and the access network device 122 in fig. 2) provided in the embodiments of the present application may be a new radio node B (gNB), which is a device in a network for accessing a terminal to a wireless network, and is mainly responsible for radio resource management, quality of service (qual ity of service, qoS) management, data compression, encryption, and other functions on an air interface side. The access network equipment is deployed at a position close to the UE, provides a network access function for authorized users in a specific area, and can determine transmission tunnels with different qualities according to the level of the users, the service requirements and the like to transmit user data.

Alternatively, the access network device may be a node in a radio access network, also referred to as a base station, and also referred to as a radio access network (radio access network, RAN) node (or device). The access network device may include an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in a long term evolution (long term evolution, LTE) system or an evolved LTE system (LTE-advanced, LTE-a), such as a conventional macro base station eNB and a micro base station eNB in a heterogeneous network scenario, or may also include a next generation Node B (next generation Node B, gNB) in a 5G New Radio (NR) system, or may also include a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a transmission receiving point (transmission reception point, TRP), a home base station (e.g., home evolved NodeB, or home Node B, HNB), a Base Band Unit (BBU), a base band pool BBU pool, or a WiFi access point (access point, AP), or may also include a concentrated unit (central ized unit, CU) and a distributed access network (DU) in a cloud (cloud radio access network, cloudRAN) system, and the present application is not limited thereto. In a separate deployment scenario where the access network device includes a CU and a DU, the CU supports protocols such as radio resource control (radio resource control, RRC), packet data convergence protocol (packet data convergenc eprotocol, PDCP), service data adaptation protocol (service data adaptation protocol, SDAP), etc.; the DUs support mainly radio link control layer (radio link control, RLC), medium access control layer (media access control, MAC) and physical layer protocols. For convenience of description, the above-mentioned access network devices with various names will be collectively referred to as an access network device, and are used for illustrating the method and apparatus provided by the present application.

The core network device (e.g., the core network device 110 in fig. 2) provided by the embodiment of the present application is responsible for maintaining subscription data of a mobile network, managing network elements of the mobile network, and providing session management, mobility management, policy management, security authentication, and other functions for the UE. The core network equipment can provide network access authentication for the UE when the UE is attached; when the UE has a service request, network resources are allocated to the UE; updating network resources for the UE when the UE moves; providing a fast recovery mechanism for the UE when the UE is idle; releasing network resources for the UE when the UE is detached; when the UE has traffic data, a data routing function is provided for the UE (e.g., forwarding uplink data to the data network, or receiving UE downlink data from the data network, forwarding to the access network device and thus sending to the UE). The core network device may comprise a core network user plane element (or simply user plane element) and a core network control plane element (or simply control plane element). And the core network user plane network element receives the data from the terminal and forwards the data. The core network control plane network element can define the processing action of the user plane network element on the data, and the core network control plane network element sends the forwarding rule of the data to the core network user plane network element. When the data arrives at the core network user plane network element, the core network user plane network element carries out corresponding processing on the data according to the forwarding rule issued by the core network control plane network element, and completes the forwarding of the data. The core network control plane network element may store one or more of information of the terminal, where the information of the terminal may include at least one of an identifier of the terminal and information of an access network device to which the terminal belongs. The information of the terminal stored in the core network control plane network element includes, but is not limited to, the above information, which is not limited herein.

Referring to fig. 3, fig. 3 is another architecture diagram of a 5G communication system. In the communication system architecture shown in fig. 1, the core network device may further refine the plurality of functional modules. Wherein the user plane network element of the core network comprises a user plane function (user plane function, UPF); the control plane network elements of the core network comprise authentication server functions (authentication server function, AUSF), access and mobility management functions of the core network (access and mobility management function, AMF), session management functions (session management function, SMF), network slice selection functions (network slice selection function, NSSF), network opening functions (network exposure function, NEF), network function warehousing functions (network function repository function, NRF), unified data management (Unified Data Management, UDM), policy control functions (policy control function, PCF), application functions (application function, AF). The control plane of the core network adopts a service architecture, and the interaction between the control plane network elements adopts a service calling mode to replace a point-to-point communication mode in the traditional architecture. In the service architecture, the control plane network elements can open services to other control plane network elements for other control plane network elements to call, and in point-to-point communication, a set of specific messages exist at a communication interface between the control plane network elements, and the messages can only be used by the control plane network elements at two ends of the interface in communication.

For easy understanding, the following will briefly describe the functions of each network element or node in the core network:

The network data analysis network element may collect data from various Network Functions (NF), such as policy control network elements, session management network elements, user plane network elements, access management network elements, application function network elements (through network capability open function network elements), and analyze and predict. In a 5G communication system, the network data analysis network element may be a network data analysis function (network data analytics function, NWDAF), and in future communication systems (e.g., 6G communication systems), the network data analysis network element may still be an NWDAF network element, or may have other names, which is not limited by the present application.

In a 5G communication system, the application function element may be an AF, and in a future communication system (e.g. a 6G communication system), the application function element may still be an AF element, or may have other names, which is not limited by the present application.

It should be appreciated that the network elements or functions described above may be either network elements in a hardware device, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). Alternatively, the network element or the function may be implemented by one device, or may be implemented by a plurality of devices together, or may be a functional module in one device, which is not specifically limited in the embodiment of the present application.

For convenience of explanation, the following description will take an access management network element as an AMF network element, and a session management network element SMF as an SMF network element. Further, the AMF network element is abbreviated as AMF, and the SMF network element is abbreviated as SMF. Namely, the AMF described later in the application can be replaced by an access management network element, and the SMF can be replaced by a session management network element, which will not be described in detail later.

The configuration method of the subscription data of the mobile network (for convenience of description, the method provided by the application can be simply referred to as the method) can be applied to the online account opening of the terminal (such as the UE) of the NPN, and the subscription data of the UE in the target NPN can be configured through the CP or the UP. Wherein, CP configuration: when configuring the subscription data of the UE at the target NPN by the CP, the UDM or the configuration server (provisioning server, PS) carries new subscription data (i.e., NPN subscription data configured to the UE) in the NAS message to the UE by the AMF. The configuration of the subscription data of the UE at the target NPN by the CP may be performed in two ways:

mode one: subscription data is configured for the UE during UE registration, UE configuration update (UE Configuration Update, UCU) or UE parameter update (UE Parameter Update, UPU). At this time, the UE is required to support receiving subscription data through NAS MM message during registration, UCU or UPU, the ON AMF is interworked with the SO UDM, the SO UDM is interworked with PS, and update of the subscription data of the UE is supported.

Mode two: the subscription data is configured for the UE in the secondary authentication process (including session secondary authentication and/or slice secondary authentication), at this time, the UE is required to support receiving the subscription data through NAS MM and/or SM messages in the secondary authentication process, and the AMF or SMF can interwork with the PS and support acquiring the subscription data of the UE.

UP configuration: when the UE configures the subscription data of the target NPN through the UP, the PS carries the new subscription data to the UE in a protocol data unit (protocol data unit, PDU) session through the UPF. At this time, the UE application layer is required to support interaction with PS, and the UE subscription data is updated through the application layer.

The method provided by the application can determine the configuration mode for configuring the subscription data for the UE according to the capability information (which can be called as first capability information for convenience in description) of the UE, the capability information (which can be called as second capability information for convenience in description) of the So and the capability information (which can be called as third capability information for convenience in description) of the ON, and can acquire the subscription data of the target NPN configured for the UE from the corresponding target network element based ON the determined configuration mode and configure the subscription data to the UE. Here, the capability information of the UE includes whether the UE supports CP configuration, whether the UE supports UP configuration, and whether the UE prefers CP configuration or UP configuration in case of supporting both CP configuration and UP configuration, in other words, the capability information of the UE may be used to indicate a UE supporting and/or preferred subscription data configuration manner. Also, the capability information of the SO includes whether the SO supports the CP configuration, whether the SO supports the UP configuration, and whether the SO prefers the CP configuration or the UP configuration in the case of supporting both the CP configuration and the UP configuration, in other words, the capability information of the SO may be used to indicate the SO support and/or the preferred subscription data configuration manner. The capability information of the ON includes whether the ON supports the CP configuration, whether the ON supports the UP configuration, and whether the ON prefers the CP configuration or the UP configuration in the case of supporting the CP configuration and the UP configuration at the same time, in other words, the capability information of the ON may be used to indicate the ON support and/or the preferred subscription data configuration manner.

The ON is to log in the network, and in an application scenario supporting the online account opening of the UE, network elements involved in the ON include AMF, UDM and SMF. SO is a new subscription owner, where SO may also be understood as a subscription network, and in an application scenario supporting online account opening of UE, the network elements involved in SO include PS (PS may be used as a subscription configuration network element) and UDM. The AMF can acquire the capability information of the UE from the UE or the DCS or the UDM, can acquire the capability information of the ON from the local configuration or the intercommunication protocol, and can acquire the capability information of the SO from the intercommunication protocol or the DCS or the PS. In different configurations, the AMF may also have different ways to obtain the capability information of the UE, SO and ON. The AMF determines a target configuration mode for configuring the UE subscription data ON the UE according to the capability information of the UE, SO and ON, and can determine the path for authenticating the UE and configuring the UE in the subscription data after determining the target configuration mode, SO that the configuration of the subscription data of the terminal ON the target subscription network can be performed based ON the target configuration mode. Here, the AMF performing configuration of the subscription data of the terminal on the target subscription network may include sending a subscription data acquisition request to the PS to notify the PS to configure the subscription data of the UE on the target subscription network, or notifying the UE to initiate configuration of the subscription data of the UE on the target subscription network. For example, if a default credential of a default DCS is configured on the UE (i.e., the UE uses a UE ID of the DCS), in the process of online account opening of the terminal, the DCS can be used to authenticate and authorize the UE information; if the default 3GPP subscription is configured on the UE (namely, the UE uses the UE ID of the UDM), the UE can be authenticated and authorized through the AUSF and the UDM in the process of online account opening of the terminal. The AMF and/or SMF may acquire subscription data configured to the UE from the PS or UDM when the UE authentication authorization is passed, and may configure the subscription data to the UE by means of CP configuration.

The method provided by the application is illustrated in the following by combining fig. 4 to 8, which are a determination of the configuration mode of the UE subscription data, and the acquisition paths of the UE, SO and ON information in different configuration modes, and the paths from the configuration data to the UE.

Embodiment one:

referring to fig. 4, fig. 4 is an interaction schematic diagram of a method for configuring subscription data according to the present application. In the embodiment shown in fig. 4, it may be assumed that a default credential of DCS is configured ON the UE, and the UE ID of DCS is used for the identification of the UE, then DCS authenticates the UE for the first time in the registration process of the UE, and the AMF determines that the target configuration mode from the configuration data to the UE is CP configuration according to the capability information of the UE, the capability information of SO and the capability information of ON, and then PS obtains the subscription data of the target SO after authenticating the UE, and then sends the configuration data to the UE through the CP configuration data. The method provided by the present application will be exemplified in connection with the steps of fig. 4. As shown in fig. 4, the method provided by the present application may include the steps of:

s41, the access network equipment broadcasts the ON capability information.

In some possible embodiments, the access network device is an ON access network device, and the ON capability information includes whether the ON supports CP configuration of the subscription data, whether supports UP configuration of the subscription data, or whether CP configuration or UP configuration is preferred when CP configuration and UP configuration of the subscription data are supported simultaneously.

S42, the UE selects ON according to the self capability and the broadcast information.

In some possible embodiments, the broadcast information is ON capability information broadcast by the access network device. The UE's own capabilities include whether the UE supports CP configuration of subscription data, whether it supports UP configuration, or both CP configuration and UP configuration of subscription data, with CP configuration or UP configuration being preferred. It may be appreciated that the UE may learn a configuration manner of supporting the subscription data by one or more ON from a broadcast message of one or more ON, and select, in combination with its own capability, a CP configuration that also supports the subscription data, or a target ON that also supports the CP configuration and the UP configuration of the subscription data, from one or more ON. It can be appreciated that when the UE supports both CP configuration and UP configuration of the subscription data, the UE may select the CP configuration of the subscription data, or support ON of the CP configuration and UP configuration of the subscription data as a target ON. The specific implementation manner of the target ON selection by the UE may be determined according to the actual application scenario, which is not limited herein. For convenience of description, in the configuration process of the subscription data, the ON is described by taking the target ON as an example, which will not be described in detail later.

S43, the UE sends a radio resource control message to the access network equipment.

In some possible embodiments, the UE's capability information and registration request may be carried in a radio resource control (radio resource control, RRC) message sent by the UE to the access network device. The registration request may carry the UE ID of DCS and capability information of the UE. Here, the capability information of the UE includes a subscription data configuration manner supported by the UE and indication information that the UE prefers CP configuration or UP configuration when supporting CP configuration and UP configuration of the subscription data at the same time. Optionally, the registration request may also carry the SO ID of the target SO. Here, the target SO is the SO of the target NPN that the UE requests to access when opening an account online, and will not be described in detail.

S44, the AMF receives a registration request of the UE from the access network equipment.

In some possible embodiments, the access network device may select an AMF supporting the UE capability according to the capability information of the UE, and forward the registration request to the AMF. Alternatively, the access network device may send an N2 message to the AMF, and carry the above-mentioned registration request in the N2 message. It may be understood that the registration request forwarded by the access network device to the AMF includes at least the UE ID of the UE in DCS (i.e. DCS UE ID). Optionally, the registration request may carry capability information of the UE, and may also carry an SO ID of the target SO. Here, the capability information of the UE carried in the registration request may be capability information of the UE configured by default, including information such as whether the UE is configured by default to support CP configuration, whether the UE is configured by UP configuration, and/or preferred CP configuration or UP configuration.

S45, the AMF initiates an authentication request.

In some possible embodiments, the AMF may determine that the DCS UE needs to be authenticated according to the DCS UE ID carried in the registration request, and may further select the AUSF and DCS, and initiate the authentication request to the AUSF and DCS. Here, the authentication request includes at least DCS UE ID, and the authentication request may further include the SO ID of the target SO.

In some possible implementations, the AMF may send an authentication request message to the AUSF and forward the authentication request message to the DCS via the AUSF. And the DCS and the UE can pass through ON, and whether the UE is legal or not is authenticated according to the certificate of the UE.

S46, the DCS sends an authentication response to the AMF through the AUSF, and the AMF sends the authentication response to the UE.

In some possible embodiments, after the DCS authenticates that the UE is legitimate, an authentication response message may be sent to the AMF through the AUSF. The authentication response message carries capability information of the UE, capability information of the SO, SO ID and/or PS address information, etc. The AMF may acquire capability information of the UE from the authentication response message if the DCS is owned by the device manufacturer, and may also acquire capability information of the SO, SO ID of the target SO, or PS address if the DCS is owned by the ON or SO.

Here, the capability information of the UE carried in the authentication response message may be capability information of the UE subscription, including whether the UE subscription supports CP configuration, whether the UE subscription supports UP configuration, and/or information such as preferred CP configuration or UP configuration. Optionally, if the registration request received by the AMF from the access network device carries the SO ID of the target SO, the authentication response message may only provide the information of the target SO, such as the SO ID of the target SO and the capability information. If the registration request received by the AMF from the access network device does not carry the SO ID of the target SO, the authentication response message carries one or more SO IDs, capability information, and the like, which can be specifically determined according to the actual application scenario, and is not limited herein. The AMF may store information of one or more SOs, SO that the target SO and capability information of the target SO may be determined according to the stored information of the one or more SOs after acquiring the SO ID of the target SO from the UE.

In some possible implementations, after the AMF receives the authentication response message, a NAS security mode command (NAS Security Mode Command) may be exchanged with the UE to establish a secure connection.

S47, the AMF acquires the SO ID of the target SO from the UE.

Alternatively, in some possible embodiments, if the AMF does not obtain the SO ID of the target SO from the registration request, the AMF may send an SO ID obtaining request message to the UE through the access network device. The UE may feed back an SO ID acquisition response message to the AMF through the access network device, and carry the SO ID of the target SO in the SO ID acquisition response message.

S48, the AMF determines a target configuration mode according to the UE capability information, the SO capability information and the ON capability information.

In some possible embodiments, the AMF may obtain the capability information of the ON from the local configuration or the interworking protocol, or may obtain the capability information of the SO from the interworking protocol, which may be specifically determined according to the actual application scenario, which is not limited herein. After the AMF determines the target SO, a target configuration mode for configuring the subscription data of the target SO to the UE can be determined according to the UE capability information, the capability information of the target SO and the capability information of the ON, and then the configuration of the subscription data of the UE in the target SO can be initiated based ON the target configuration mode. Here, the target configuration mode is a subscription data configuration mode that is supported and preferred by the UE, ON, and SO.
