Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a terminal policy configuration method, device and network element. Background Art

[0002] In current technologies, the access network discovery and selection policy (ANDSP) and the terminal route selection policy (URSP) are provided by the 5G core network to the terminal for access network selection or route selection.

[0003] The existing solution is that when a service is activated, BOSS generates URSP or ANDSP data containing slice information, writes it to the 5G network's network element policy control function (PCF) or unified data repository (UDR), and sends it to the terminal through the access and mobility management function (AMF) in the service process to assist the terminal in selecting an access network or route based on the service. For example, Figure 1 As shown:

[0004] 1. When a customer handles business at a business hall, BOSS writes the terminal's ANDSP policy-related data (including PLMN identification, location data, SSID list, etc.) or URSP policy-related data (application description, slice information, DNN, etc.) into the PCF / UDR.

[0005] 2. After receiving the information, the PCF / UDR generates and saves the terminal's ANDSP policy data or URSP policy locally;

[0006] 3. PCF / UDR sends ANDSP policy or URSP policy data to AMF via NAS signaling;

[0007] 4. After receiving the signaling, the AMF forwards the NAS signaling to send the ANDSP policy or URSP policy data to the terminal.

[0008] 5. After receiving the policy data, the terminal saves and processes it, and updates the local wireless access network selection rule or routing selection rule information after successful processing;

[0009] 6. The terminal performs radio access network selection or route selection based on the locally updated radio access network selection rule or route selection rule information.

[0010] In summary, in the existing technology, after ANDSP and URSP data are generated in the core network, they are sent to the terminal by the core network, and the terminal selects the access network or routing strategy. However, the existing technical methods have the following problems:

[0011] Low adjustment efficiency. Data is generated and adjusted by the core network based on changes in terminal service needs. The core network has high network stability requirements, resulting in a long data adjustment cycle and low efficiency, making it difficult to respond to changes in regional terminal service needs in a timely manner.

[0012] This is not conducive to the development of edge services: Currently, core network elements are mostly deployed centrally. However, edge services require an adjustment path from the existing edge -> centralized -> edge. This often makes core network elements a bottleneck, hindering the rapid development of edge services.

[0013] Affecting the stability of the core network. Due to the need to adjust URSP or ANDSP for decentralized and edge business applications, terminal-related policy data is distributed through the network interface, affecting the stability of the core network in providing full-network services. Summary of the Invention

[0105] The terminal policy configuration method provided by the embodiment of the present invention can be applied to Figure 2 The edge computing network architecture shown is used to enable edge applications; Figure 2 As shown:

[0106] EES (Edge Enabler Server) can provide support functions to EEC (Edge Enabler Client) and EAS (Edge Application Server), and EES can call core network capabilities.

[0107] The EEC is used to provide the necessary support functions to the AC (Application Client).

[0108] ECS (Edge Configuration Server) is used to provide the necessary support functions for EEC to connect to EES.

[0109] like Figure 3 As shown, an embodiment of the present invention provides a terminal policy configuration method, which is executed by an edge enabling server network element EES, including:

[0110] Step 301: Obtain terminal-related subscription data and policy data provided by the network through the core network element, and generate terminal policy information locally in the EES;

[0111] In this step, EES obtains the terminal policy data of the network locally through the authorization of the core network element, and constructs the terminal policy for the local terminal locally. EES supports generating local terminal policies by obtaining data from the network through the core network element, including URSP, ANDSP and other policies.

[0112] Step 302: When the service triggers the terminal policy adjustment, the terminal policy is updated and the updated terminal policy information is sent to the terminal;

[0113] In this step, the local application triggers the adjustment of the terminal policy according to the business situation. The EES updates the local terminal policy and pushes the updated terminal policy to the terminal, thereby adjusting the terminal policy selection.

[0114] like Figure 4 As shown, the terminal policy configuration method provided in the embodiment of the present application is aimed at the edge enabling server network element EES, edge application EAS and edge terminal (including AC and EEC) in the edge factory or park. The core network network element is specifically the core network control plane network element, which adopts regional (such as province or region) or national centralized scenarios. For example, the core network network elements include: NEF (Network Exposure Function, network open function network element), PCF (Policy Control function, policy control function network element), UDM (Unified Data Management, unified data management function network element).

[0115] In an embodiment of the present invention, sinking terminal policy data to the campus / factory network can provide better service quality and service experience for local services, and local services often need to adjust terminal policies based on local terminal conditions and business needs. Therefore, in step 302 of the embodiment of the present invention, the local application triggers the adjustment of the terminal policy based on the business conditions, the EES updates the local terminal policy, and pushes the updated terminal policy to the terminal, thereby realizing the adjustment of terminal policy selection, thereby meeting the needs of business innovation and development.

[0116] In at least one optional embodiment of the present invention, step 301 includes:

[0117] Receive a terminal policy subscription request sent by the edge application server network element EAS;

[0118] Sending a first terminal policy acquisition request to a network open function NEF according to the terminal policy subscription request;

[0119] Receive terminal-related subscription data and policy data sent by NEF.

[0120] As an optional embodiment, the terminal policy subscription request includes at least one of the following:

[0121] Terminal identification;

[0122] Subscribed policy type; the policy type includes access network discovery and selection policy ANDSP and / or terminal routing selection policy URSP;

[0123] Identification code osid;

[0124] Notification content;

[0125] Notice address;

[0126] First indication information indicating that the terminal supports ANDSP;

[0127] The second indication information instructs the terminal to indicate the URSP.

[0128] As another optional embodiment, the first terminal policy acquisition request includes at least one of the following:

[0129] Terminal identification;

[0130] Subscribed policy type; the policy type includes access network discovery and selection policy ANDSP and / or terminal routing selection policy URSP;

[0131] Identification code osid;

[0132] First indication information indicating that the terminal supports ANDSP;

[0133] The second indication information instructs the terminal to indicate the URSP.

[0134] In at least one optional embodiment of the present application, the EES supports notifying the terminal of the relevant EAS after generating the terminal policy locally. That is, after step 301, the method further includes:

[0135] Sending a subscription terminal policy notification to the EAS, wherein the subscription terminal policy notification includes third indication information that the EES has local terminal policy information;

[0136] A notification response sent by the ESA is received, where the notification response includes fourth indication information indicating that the subscription has been established and a subscription session identifier.

[0137] In another optional embodiment of the present invention, EES supports pushing local terminal policies to the terminal according to the request of EAS, that is, step 302 includes:

[0138] Receive a terminal policy adjustment request sent by the EAS, wherein the terminal policy adjustment request includes a terminal identifier and reference information for adjusting a corresponding terminal policy;

[0139] According to the terminal policy adjustment request, local terminal policy information is updated.

[0140] Optionally, after the EAS receives the fourth indication information included in the subscription terminal policy notification sent by the EES, the EAS sends a terminal policy adjustment request to the EES. For example, the reference information corresponding to the terminal policy adjustment includes: the adjustment policy type, and adjustment policy-related data (such as preferred WLAN information for ANDSP and application address information for URSP). The EES updates and generates local terminal policy information based on the received terminal identifier, adjustment policy type, and adjustment policy-related data.

[0141] Furthermore, step 302 sends the updated terminal policy information to the terminal, including:

[0142] Determining, according to the terminal identifier included in the terminal policy adjustment request, an edge enabling client network element EEC to which the terminal belongs;

[0143] Sending a first push notification to the EEC to which the terminal belongs, wherein the first push notification includes: a terminal policy acquisition type and an address of the policy data (such as a uniform resource locator URL); for example, the terminal policy acquisition type includes: immediate acquisition and / or acquisition after the current service is completed;

[0144] receiving a second terminal policy acquisition request sent by the EEC to which the terminal belongs according to the first push notification;

[0145] According to the second terminal policy acquisition request, a terminal policy acquisition response is sent to the EEC to which the terminal belongs, wherein the terminal policy acquisition response includes the updated terminal policy information; and the updated terminal policy information is sent to the application client AC of the terminal through the EEC to which the terminal belongs.

[0146] Optionally, the second terminal policy acquisition request includes: a terminal policy type requested to be acquired; the policy type includes ANDSP and / or URSP.

[0147] Among them, EEC supports the selection and execution of terminal policies by interacting with AC based on the received terminal policy information; that is, after EEC receives the terminal policy acquisition response, it takes out the updated terminal policy information from the response and saves it locally; EEC interacts with AC, notifies AC to update the local terminal policy, and AC selects access network or terminal route based on the updated local terminal policy information.

[0148] As an optional embodiment, the method further includes:

[0149] receiving update result feedback information sent by the EEC to which the terminal belongs;

[0150] According to the update result feedback information, a terminal policy adjustment notification is sent to the EAS; the terminal policy adjustment notification is used to notify the EAS of the terminal policy adjustment result.

[0151] In an embodiment of the present invention, the EEC sends update result feedback information to the EES. After receiving the information, the EES sets the terminal policy information local updated flag according to the feedback result, and sends a policy adjustment notification to the EAS to inform the EAS of the terminal policy adjustment result. Optionally, the application can return a response after processing the terminal policy adjustment result.

[0152] In at least one optional embodiment of the present invention, the terminal policy information includes:

[0153] Policy type and corresponding policy rule data.

[0154] For example, for ANDSP, the corresponding policy rule data includes: rule selection order (such as service set identifier SSID priority order), selection mode; for URSP, the corresponding policy rule data includes: rule priority order, slice identifier, data network identifier DNN, etc.; no specific limitation is made here.

[0155] In summary, in the embodiment of the present invention, the EES based on edge computing migrates the generation and update capabilities of terminal policy information to the local edge network for provision and execution; the terminal policy adjustment can be triggered by the application according to the service usage of local users, realizing the dynamic issuance and rapid deployment of local terminal network policies, improving efficiency, and facilitating the rapid development of edge network services; and the policy data related to edge network terminals reduces the links and times issued by the core network, reduces the processing load of the centralized core network and the impact on stability, and reduces the issuance delay from the centralized core network to the edge terminal, which is conducive to improving network quality and enhancing service experience. Moreover, when a core network failure occurs, this method can perform network switching by updating the terminal policy and continue to provide edge park / factory services, thereby reducing the impact of network failures on edge park / factory services.

[0156] like Figure 5 As shown, an embodiment of the present invention further provides a terminal policy configuration method, which is executed by a network open function network element NEF, including:

[0157] Step 501: Acquire the terminal-related subscription data and policy data according to the request of the edge enabling server network element EES;

[0158] In step 502, the terminal's subscription data and policy data are sent to the EES. The EES then generates terminal policy information locally based on the terminal's subscription data and policy data. This enables the edge computing-based EES to migrate the generation and update capabilities of terminal policy information to the local edge network for provision and execution.

[0159] In at least one optional embodiment of the present invention, step 401 includes:

[0160] Receive a first terminal policy acquisition request sent by EES;

[0161] Sending an authorization request to the unified data management function network element UDM according to the first terminal policy acquisition request;

[0162] Receive the authorization result returned by the UDM, the authorization result including: the permission identifier that the terminal policy can locally issue and the terminal-related contract data;

[0163] Sending a third terminal policy acquisition request to the policy control function network element PCF to which the terminal belongs; the third terminal policy acquisition request includes: a terminal policy authorization issuance instruction;

[0164] Receive terminal-related policy data sent by PCF.

[0165] In this embodiment of the present invention, the NEF supports proxying the EES's first terminal policy acquisition request, authorizing the UDM to obtain the user's subscription data and network terminal policy data, and then obtaining the user's terminal-related subscription data based on the authorization. The NEF also supports proxying the EES and, based on the UDM's authorization, obtaining terminal-related policy data, such as URSP and ANDSP policy data, from the PCF.

[0166] The UDM supports authorization processing for sending terminal-related subscription data and policy data to external network elements (such as EES) in the core network. The UDM also supports sending terminal-related subscription data to external network elements via the NEF after authorization is approved. The PCF supports sending terminal-related policy data to external network elements via the NEF based on authorization from the UDM.

[0167] In at least one optional embodiment of the present invention, the first terminal policy acquisition request includes at least one of the following:

[0168] Terminal identification;

[0169] Subscribed policy type; the policy type includes access network discovery and selection policy ANDSP and / or terminal routing selection policy URSP;

[0170] Identification code osid;

[0171] First indication information indicating that the terminal supports ANDSP;

[0172] The second indication information instructs the terminal to indicate the URSP.

[0173] As an optional embodiment, the third terminal policy acquisition request further includes at least one of the following:

[0174] Terminal identification;

[0175] The acquired policy type includes ANDSP and / or URSP;

[0176] Change notification address.

[0177] After PCF receives the third terminal policy acquisition request, it determines that the network's terminal policy data can be issued based on the terminal policy authorization issuance indication, returns the terminal-related policy data of the specified terminal identifier to NEF based on the policy type, and sets the issued identifier locally. The issued identifier is used to indicate that the policy data will be subsequently issued by an external network element, and saves the change notification address.

[0178] In summary, in the embodiment of the present invention, EES obtains the terminal policy data and contract data of the network locally through NEF, and EES generates terminal policy information locally in EES based on the contract data and policy data related to the terminal. In this way, the EES based on edge computing can migrate the generation and update capabilities of terminal policy information to the local edge network for provision and execution; since the policy data related to the edge network terminal reduces the links and times of being sent down by the core network, the processing load of the centralized core network and the impact on stability are reduced, and the delay in sending from the centralized core network to the edge terminal is reduced, which is conducive to improving network quality and enhancing service experience. Moreover, when a core network failure occurs, this method can perform network switching by updating the terminal policy and continue to provide edge campus / factory services, thereby reducing the impact of network failures on edge campus / factory services.

[0179] In order to more clearly describe the terminal policy configuration method provided by the embodiment of the present invention, the terminal policy configuration method is divided into two examples for illustration below.

[0180] Example 1: The network terminal policy data is sent to the EES process, such as Figure 6 As shown:

[0181] Step 61: EAS sends a terminal policy subscription request to EES, carrying the terminal identifier, subscription policy type, OSID, notification content, and notification URL; optionally, for subscription to ANDSP policy, it may also carry information indicating that the terminal supports ANDSP; for subscription to URSP policy, it may carry information indicating that the terminal supports USRP;

[0182] Optionally, EES returns a terminal policy subscription response;

[0183] Step 62: The EES obtains the terminal identifier based on the received terminal policy subscription request and sends a first terminal policy acquisition request to the NEF, carrying information such as the terminal identifier, policy type (ANDSP policy, URSP policy), and OSID. Optionally, for acquiring ANDSP policy, the request may also carry information indicating that the terminal supports ANDSP.

[0184] Optionally, NEF returns a response for obtaining terminal policy-related data;

[0185] Step 63: The UDM has a terminal policy that the user has subscribed to that allows the terminal policy to be issued locally. The NEF queries the UDM for the terminal policy that allows the terminal policy to be issued locally based on the terminal ID.

[0186] Step 64: The UDM returns an authorization result, which carries a flag indicating that the terminal policy can be issued locally, and user subscription data related to the terminal.

[0187] In step 65, the NEF saves the received user subscription data related to the terminal and, based on the permission flag in the received authorization result, determines that the network's terminal policy data can be delivered to the EES. The NEF sends a third terminal policy acquisition request to the PCF to which the terminal belongs. The request carries the terminal identifier, acquisition policy type, terminal policy authorization delivery indication, and change notification address.

[0188] Step 66: After receiving the terminal policy authorization instruction, the PCF determines that the terminal policy data of the network can be issued. According to the obtained policy type, the terminal policy data of the specified terminal identifier is returned to the NEF, and the issued identifier data is set locally to indicate that the data will be subsequently issued by the external local network element, and the change notification address is saved.

[0189] Step 67: After receiving the terminal-related policy data returned by the PCF, the NEF sends the received terminal-related subscription data and the terminal-related policy data to the EES; optionally, the EES returns a response after receiving the data;

[0190] In step 68, the EES generates terminal policy information based on the received terminal-related subscription data and terminal-related policy data. For example, for ANDSP, this includes rule selection rules (SSID priority order) and selection mode; for URSP, this includes rule priority order, slice identifier, DNN, etc. After completing the policy data generation, the EES sends a subscription terminal policy notification to the application, which carries an indication that the terminal policy information is locally available.

[0191] Step 69: After receiving the subscription terminal policy notification, the EAS returns a response, which carries a subscription establishment indication and a subscription session identifier.

[0192] Example 2: EES pushes terminal policy information to EEC based on policy adjustment request, such as Figure 7 As shown:

[0193] In step 71, the EAS sends a terminal policy adjustment request to the EES based on the indication that the terminal policy information in the received terminal policy subscription notification is locally available. The request carries the UE identifier and reference information for adjusting the terminal policy. The reference information includes the adjustment policy type and data related to the adjustment policy (such as preferred WLAN information for ANDSP and application address information for URSP). Optionally, the EES returns a response after receiving the request.

[0194] Step 72: Update and generate local terminal policy information based on the received terminal identification, adjustment policy type, and adjustment policy reference information;

[0195] Step 73: The EES obtains the EEC information based on the terminal identifier and sends a first push notification to the EEC to which the UE belongs. The push notification carries the acquisition type (immediate, after the current service is completed, etc.) and the terminal policy information URL. Upon receiving the notification, the EEC returns a response carrying the selected acquisition type.

[0196] Step 74: The EEC sends a second terminal policy acquisition request to the EES based on the selected acquisition type and the URL obtained from the push notification. The request carries the acquisition terminal policy type (ANSDP, URSP).

[0197] Step 75: After receiving the message, EES returns a terminal policy acquisition response, which carries the user terminal policy information. The terminal policy information includes the policy type (ANSDP, URSP) and the corresponding policy rule data.

[0198] Step 76: After receiving the response, the EEC extracts the terminal policy information from the response and saves it locally; the EEC interacts with the AC and notifies the AC to update the local terminal policy; the AC selects an access network or terminal route based on the updated local terminal policy;

[0199] Step 77, EEC sends update result feedback information to EES;

[0200] Step 78: After receiving the feedback, the EES updates the local user terminal policy information according to the feedback information and sets the data local updated flag;

[0201] Step 79: The EES sends a terminal policy adjustment notification to the EAS, notifying the EAS of the terminal policy adjustment result. Optionally, the EAS processes the terminal policy adjustment result and returns a response.

[0202] In summary, if Figure 8As shown, in the embodiment of the present invention, EES obtains the network's terminal policy data and contract data locally through NEF, generates ANDSP or URSP policies, and opens them to EAS as local capabilities. When the EAS service triggers the adjustment of the terminal policy, EES updates the local terminal policy data and sends the updated ANDSP or URSP policy to the terminal, which then performs access network or route selection. In the embodiment of the present invention, the application can trigger terminal policy adjustment based on the service usage of local users, thereby realizing dynamic sending and rapid deployment of network policies based on local terminals, improving efficiency, and facilitating the rapid development of edge network services. In addition, the policy data related to edge network terminals reduces the links and times sent by the core network, reduces the processing load of the centralized core network and its impact on stability, and reduces the delay in sending from the centralized core network to the edge terminal, which is beneficial to improving network quality and enhancing service experience.
