[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on and claims the priority of Chinese patent application with application number 202311801060.9 and application date December 25, 2023. The entire content of this Chinese patent application is incorporated herein by reference into this disclosure. Technical Field

[0003] The present application belongs to the field of communication technology, and in particular relates to a data processing method, apparatus, device, computer storage medium, and program product. Background Art

[0004] "Cross-domain user roaming" means that after a user leaves their service home location, the network side supports the continuation of the user plane path from the visited location to the home location by inserting an I-UPF (Intermediate User Plane Function) at the visited location. Currently, for 5G (5th-Generation Mobile Communication Technology) campus services deployed in the area where the industry headquarters is located, users in areas outside the service home location can access the services of the industry headquarters, that is, the local DN (Data Network), without manually changing the terminal's default DNN (Data Network Name). At the same time, they can also smoothly access the Internet without changing the card or number. The main service scenario currently uses ULCL (Uplink Classifier) ​​diversion technology.

[0005] In the existing technical solution, the ULCL UPF (User Plane Function) and the primary anchor point UPF are deployed together in the city (outside the campus), and the secondary anchor point UPF is deployed inside the campus. The UPF that integrates the ULCL in each city and the primary anchor point and the secondary anchor point UPF in the campus open up the N9 interface. In the user's PDU (Protocol Data Unit) session process, the SMF (Session Management Function) will send the diversion rules to the UPF that integrates the ULCL in the city and the primary anchor point. In the subsequent data transmission process, the data packets that match the diversion rules will be forwarded to the secondary anchor point UPF and forwarded to the local DN through the N6 interface. Other data packets will be forwarded to the primary anchor point UPF and forwarded to the Internet through the N6 port.

[0006] However, the aforementioned technical solution forces local data flows within the industrial park to bypass the prefectural UPF, resulting in traffic detours. Furthermore, this solution cannot guarantee that data will remain within the industrial park, which, given the sensitivity of certain industry customers to data leaving the industrial park, cannot effectively meet user needs. Therefore, the industry still needs a new business data diversion solution to effectively reduce traffic detours and improve data security within the industrial park. Summary of the Invention

It should be noted that the embodiments provided in this application are not intended to limit the scope of the disclosure of this application.

[0063] The following first introduces the data processing method provided in the embodiment of the present application.

[0064] FIG1 is a flow chart illustrating a data processing method according to an embodiment of the present application. The data processing method is applied to a campus uplink classifier, which supports the home primary anchor user plane function. The campus uplink classifier and the home primary anchor user plane function are integrated into one, and can be specifically deployed on an electronic device, such as a server or a terminal. As shown in FIG1 , the data processing method includes the following steps:

[0065] S110, when the user equipment initiates a creation request for a target protocol data unit session for a campus-specific service within the home location, receiving a diversion rule corresponding to the campus-specific service from the home location session management function;

[0066] S120: Based on the diversion rule, forward the data message in the target protocol data unit session to the home location primary anchor point user plane function or the home location secondary anchor point user plane function; wherein the home location primary anchor point user plane function is connected to the local data network of the campus, and the home location secondary anchor point user plane function is connected to the external data network.

[0067] An embodiment of the present application provides a data processing method, in which, when a user device initiates a creation request for a target protocol data unit session for a campus-specific service within a home location, a campus uplink classifier receives a diversion rule corresponding to the campus-specific service and sent by the home location session management function. In this way, based on the diversion rule, the campus uplink classifier forwards the data packets within the target protocol data unit session to the home location primary anchor user plane function or the home location secondary anchor user plane function. The campus uplink classifier supports the home location primary anchor user plane function. The home location primary anchor user plane function is connected to the campus's local data network, and the home location secondary anchor user plane function is connected to an external data network. As can be seen from the above description, an embodiment of the present application provides a data processing method, in which, by integrating the campus uplink classifier and the home location primary anchor user plane function within the campus, the data packets within the user's target protocol data unit session are diverted and forwarded according to the diversion rule corresponding to the campus-specific service, thereby effectively reducing traffic detours and improving overall service access efficiency, while also substantially improving the security of data within the campus.

[0068] The specific implementation of the above steps 110 to 120 is described in detail below.

[0069] In this embodiment, for example, the uplink classifier user plane function (ULCLUPF) and the home primary anchor user plane function UPF may be pre-deployed in the park, and the secondary anchor user plane function UPF may adopt the municipal UPF.

[0070] In S110, in a specific implementation, when a user equipment (UE) initiates a creation request for a target protocol data unit (PDU) session of a campus-specific service within a home location, a diversion rule corresponding to the campus-specific service is received from a home location session management function (SMF).

[0071] In S120 , in specific implementation, based on the diversion rule, the data message in the target protocol data unit PDU session is forwarded to the home primary anchor point user plane function UPF or the home secondary anchor point user plane function UPF.

[0072] Among them, the user plane function UPF of the primary anchor point at the home location is connected to the local data network of the campus, that is, the local DN, and the user plane function of the secondary anchor point at the home location is connected to the external data network Internet, thus realizing reverse diversion.

[0073] In this way, by setting up the campus uplink classifier and the home main anchor user plane function in the campus, that is, in the above-mentioned deployment method of deploying the uplink classifier user plane function (ULCLUPF) and the home main anchor user plane function UPF in the campus, the data packets that need to flow to the local DC can be directly diverted to the local area through the campus uplink classifier ULCL, ensuring that the data does not leave the campus, thereby improving the data security of the campus.

[0074] More specifically, the home primary anchor user plane function UPF can be connected to the local data network (local DN) of the campus through the N6 interface, and the home secondary anchor user plane function UPF is connected to the external data network through the N6 interface.

[0075] In addition, in some other embodiments, the UPF that integrates the campus uplink classifier ULCL and the main anchor point UPF of the home location can be connected to the N9 interface with the auxiliary anchor point UPF located in various cities to ensure that the data transmission path of the entire network is opened, so that users can access business services in the home location no matter where they are.

[0076] More specifically, forwarding the data packets in the target protocol data unit session to the home primary anchor point user plane function or the home secondary anchor point user plane function based on the diversion rule may include:

[0077] If the data packet can be used to access the campus's local data network, forward the data packet to the home primary anchor user plane function;

[0078] If the data message can be used to access the external data network, the data message is forwarded to the external data network.

[0079] According to some embodiments of the present application, optionally, considering the actual user's PDU session scenario, the data processing method may further include:

[0080] When the user equipment moves from a first coverage area within the home area to a second coverage area within the home area, receiving a data message in a target protocol data unit session forwarded by the first relay user plane function when the user equipment is in the second coverage area;

[0081] Among them, the first coverage area is the area covered by the home location primary anchor point user plane function; the second coverage area is the area not covered by the home location primary anchor point user plane function in the home location; the first relay user plane function is the user plane function within the second coverage area.

[0082] In this embodiment, when the user equipment UE moves from a first coverage area within the home area to a second coverage area within the home area, the user plane function UPF within the second coverage area acts as a first relay user plane function (I-UPF1) to forward data packets within the target protocol data unit PDU session when the user equipment is in the second coverage area.

[0083] The first coverage area may be an area covered by the user plane function of the primary anchor point in the home location; and the second coverage area may be an area not covered by the user plane function of the primary anchor point in the home location.

[0084] According to some embodiments of the present application, optionally, further considering the actual user's PDU session scenario, the data processing method may further include:

[0085] When the user equipment moves from a home location to a visited location, a data message in a target protocol data unit session when the user equipment is in the visited location is received and forwarded by a second relay user plane function, wherein the second relay user plane function is a user plane function in the visited location.

[0086] In this embodiment, when a user equipment (UE) moves from a home location to a visited location, the original PDU session loop is updated. Specifically, a user plane function (UPF) in the visited location is added as a second relay user plane function (I-UPF2). This second relay user plane function (I-UPF2) can forward data packets in the target protocol data unit (PDU) session of the UE to the campus uplink classifier (ULCL) when the UE is in the visited location.

[0087] Based on the same inventive concept, please refer to Figure 2 below, which shows a flow chart of a data processing method provided by another embodiment of the present application. Specifically, as shown in Figure 2, the embodiment of the present application provides a data processing method, which is applied to the home session management function. As shown in Figure 2, the data processing method includes:

[0088] S210, receiving a request from a user equipment to create a target protocol data unit session for a campus-specific service within a home location;

[0089] S220: In response to the creation request, a diversion rule corresponding to the campus-specific service is sent to the campus uplink classifier; the campus uplink classifier is configured to forward the data packets in the target protocol data unit session to the home primary anchor user plane function or the home secondary anchor user plane function based on the diversion rule;

[0090] Among them, the campus uplink classifier supports the home location primary anchor user plane function; the home location primary anchor user plane function connects to the campus's local data network, and the home location secondary anchor user plane function connects to the external data network.

[0091] An embodiment of the present application provides a data processing method in which a home location session management function receives a user device's request to create a target protocol data unit session for a campus-specific service within a home location. In response to the creation request, the home location session management function sends a diversion rule corresponding to the campus-specific service to a campus uplink classifier, enabling the campus uplink classifier to forward data packets within the target protocol data unit session to a home location primary anchor user plane function or a home location secondary anchor user plane function based on the diversion rule. The campus uplink classifier supports the home location primary anchor user plane function. The home location primary anchor user plane function connects to the campus's local data network, while the home location secondary anchor user plane function connects to an external data network. As can be seen from the above description, an embodiment of the present application provides a data processing method that, by integrating the campus uplink classifier and the home location primary anchor user plane function within a campus, diverts and forwards data packets within the user's target protocol data unit session according to the diversion rule corresponding to the campus-specific service. This effectively reduces traffic detours, thereby improving overall service access efficiency, and significantly enhancing data security within the campus.

[0092] The specific implementation of the above steps 210 to 220 is described in detail below.

[0093] In S210 , during specific implementation, a request from the user equipment to create a target protocol data unit session for a campus-specific service within a home location is received.

[0094] In S220, during the specific implementation, in response to the creation request, the diversion rules corresponding to the campus exclusive services are sent to the campus uplink classifier; the campus uplink classifier is used to forward the data packets in the target protocol data unit session to the home location primary anchor user plane function or the home location secondary anchor user plane function based on the diversion rules.

[0095] Among them, the campus uplink classifier supports the home location primary anchor user plane function; the home location primary anchor user plane function connects to the campus's local data network, and the home location secondary anchor user plane function connects to the external data network.

[0096] According to some embodiments of the present application, the creation request may optionally include a name of a dedicated data network corresponding to the campus-specific service; and in response to the creation request, sending a diversion rule corresponding to the campus-specific service to the campus uplink classifier may include:

[0097] When it is detected that the creation request may include the name of the dedicated data network, the diversion rule corresponding to the campus exclusive service is sent to the campus uplink classifier.

[0098] According to some embodiments of the present application, optionally, the receiving of a request from a user equipment to create a target protocol data unit session for a campus-specific service within a home location may include:

[0099] In case the first access and mobility management function in the home location receives an original creation request for the target protocol data unit session initiated by the user equipment, receiving the creation request forwarded by the first access and mobility management function;

[0100] Among them, the first access and mobility management function can be used to modify the original data network name in the original creation request to a dedicated data network name when it is detected that the target protocol data unit session is a protocol data unit session corresponding to the campus-specific service.

[0101] AMF (Access and Mobility Management Function) is responsible for user equipment (UE) identity authentication, authorization, registration, mobility management, and connection management.

[0102] In a specific implementation, when the home location (AMF1) receives the original creation request of the target protocol data unit PDU session initiated by the user equipment UE, the home location session management function SMF receives the creation request forwarded by AMF1. AMF1 can modify the original DNN in the original creation request to a dedicated DNN when it detects that the target protocol data unit session is a protocol data unit session corresponding to the campus dedicated service.

[0103] According to some embodiments of the present application, optionally, considering the actual user's PDU session scenario, the data processing method may further include:

[0104] When the user equipment moves from a first coverage area within the home area to a second coverage area within the home area, the user plane function within the second coverage area is selected as the first relay user plane function; the first relay user plane function can be used to forward the data message of the user equipment in the target protocol data unit session to the campus uplink classifier when the user equipment is in the second coverage area.

[0105] Specifically, when the user equipment UE moves from a first coverage area in the home area to a second coverage area in the home area, a user plane function in the second coverage area is selected as the first relay user plane function (I-UPF1).

[0106] The first relay user plane function (I-UPF1) may be configured to forward data packets of the user equipment UE in a target protocol data unit PDU session to the campus uplink classifier ULCL when the user equipment UE is in the second coverage area.

[0107] According to some embodiments of the present application, optionally, further considering the actual user's PDU session scenario, the user device may change the area where the user moves or drives, etc., and the data processing method may further include:

[0108] When the user equipment moves from a home location to a visited location, receiving a user context information acquisition request initiated by a visited location session management function;

[0109] In response to the user context information acquisition request, send user context information corresponding to the target protocol data unit session to the visited location session management function, so that after receiving the user context information, the visited location session management function uses the user plane function in the visited location as the second relay user plane function;

[0110] The second relay user plane function may be used to forward data packets of the user equipment in a target protocol data unit session to the campus uplink classifier when the user equipment is in a visited location.

[0111] In this embodiment, when a user equipment (UE) moves from a home location to a visited location, the home location SMF receives a user context information acquisition request initiated by the visited location session management function (I-SMF). After receiving the user context information acquisition request, the SMF responds to the user context information acquisition request by sending user context information corresponding to the target protocol data unit (PDU) session to the visited location session management function (I-SMF). Upon receiving the user context information, the visited location session management function (I-SMF) uses the user plane function in the visited location as the second relay user plane function (I-UPF2), thereby updating the original PDU session loop.

[0112] In this way, by adding the user plane function UPF in the visited location as the second relay user plane function (I-UPF2) by the I-SMF, the second relay user plane function (I-UPF2) can forward the data packets in the target protocol data unit (PDU) session of the user equipment UE to the campus uplink classifier ULCL when the user equipment UE is in the visited location.

[0113] According to some embodiments of the present application, optionally, receiving a user context information acquisition request initiated by a visited location session management function may include:

[0114] When a first access and mobility management function in a home location establishes a connection with a second access and mobility management function in a visited location, a user context information acquisition request initiated by a visited location session management function is received.

[0115] Specifically, before information exchange occurs between the home SMF and the visited I-SMF, the visited second access and mobility management function AMF2 needs to establish a connection with the home AMF1. In this way, the AMF2 in the visited area selects the I-SMF based on the user context information provided by AMF1 to establish a connection between the I-SMF and the home SMF.

[0116] To facilitate understanding of the data processing method provided by the above embodiment, the above method is described below using a specific scenario embodiment. Figure 3 is a complete scenario embodiment flow chart of the data processing method provided by an embodiment of the present application.

[0117] This scenario example is described as follows: The SMF determines traffic diversion rules based on the user's dedicated DNN and distributes them to the campus ULCL. The diversion rule configuration principle is reverse diversion, diverting campus services to the primary anchor point. The campus UPF attributes can be modified to support the combined deployment of the primary anchor point and the diversion UPF.

[0118] UPF: As a ULCL UPF, it receives traffic diversion rules issued by the SMF and diverts traffic accordingly. As an I-UPF, it supports establishing a data forwarding route from the user's current RAN (Radio Access Network) to the ULCL UPF in the service's home location when the user moves out of the service's home location. As a primary anchor UPF, it handles traffic flows accessing the local network. As a secondary anchor UPF, it handles traffic flows accessing the Internet.

[0119] Before executing the data processing method described in the above embodiment, the following preparatory operations are performed:

[0120] 1) UPF Deployment: The ULCL UPF and the primary anchor UPF are deployed together within the campus, while the secondary anchor UPF uses the municipal UPF. In this deployment, data flows from local industry DNs can be directly diverted to the local area through the ULCL UPF, ensuring that data does not leave the campus.

[0121] 2) Networking: The park's ULCL and the UPF (which is the integrated primary anchor point) are connected to the N9 interface with the UPFs located in various cities as auxiliary anchor points. This ensures that data transmission channels are available across the entire network, allowing users to access local services regardless of their location.

[0122] 3) DNN: The UDM side is a dedicated DNN signed by the industry. The primary and secondary anchor points are configured with the dedicated DNN signed by the industry users. The AMF1 in the home location turns on the DNN error correction function to correct the original DNN requested by the user to the signed dedicated DNN. In this way, the data path corresponding to the park-specific business services in the home location can be established through the PDU session process.

[0123] 4) Diversion rules: In the user's PDU session process, SMF will send the diversion rules to the campus ULCL and the UPF of the main anchor point. In the subsequent data transmission process, the data packets matching the diversion rules will be forwarded to the main anchor point UPF and forwarded to the local DN through the N6 interface. Other data packets will be forwarded to the auxiliary anchor point UPF located in the city and forwarded to the Internet through the N6 port, which is reverse diversion.

[0124] When implementing a specific business process, this scenario embodiment may specifically include the following steps:

[0125] 1) In this scenario embodiment, the user initiates the PDU session creation process in the service home location ("home location-anchor point UPF coverage area" in the figure, that is, the aforementioned first coverage area).

[0126] a) The AMF1 in the home region corrects the general DNN requested by the user to the dedicated DNN corresponding to the user's campus-specific service.

[0127] b)SMF selects the primary and secondary anchor points and ULCL UPF based on the dedicated DNN, and sends the diversion rules to the ULCL UPF.

[0128] c) When a user accesses a service, the data packets accessing the local DN on the ULCL UPF side match the diversion rules and are distributed to the primary anchor point UPF, while the data packets accessing the Internet are distributed to the secondary anchor point UPF.

[0129] 2) The user moves to the "outside the home-anchor UPF coverage area" shown in Figure 3, that is, the aforementioned second coverage area, and the user accesses the network through a base station in this area.

[0130] a) To ensure business continuity, SMF will select the UPF in the area as the I-UPF and update the PDU session to open up the "UE>RAN>I-UPF1>ULCL UPF>primary anchor point UPF>local DN" and "UE>RAN>I-UPF1>ULCL UPF>secondary anchor point UPF>Internet" data paths.

[0131] b) Users within this area can access local DN and Internet services according to the above data paths.

[0132] 3) The user moves to the "visited location" shown in Figure 3, and finally accesses the network through the base station, AMF2 and I-SMF in the area and the service home network connection.

[0133] a) To ensure business continuity, the AMF2 in the area selects the I-SMF based on the user context information to establish a connection with the home SMF.

[0134] b) I-SMF obtains user context information through interaction with SMF, selects the UPF located in the area as I-UPF2, and updates the PDU session to open up the "UE>RAN>I-UPF2>ULCL UPF>primary anchor point UPF-local DN" and "UE>RAN>I-UPF2>ULCL UPF>secondary anchor point UPF>Internet" data paths.

[0135] c) Users within this area can access local DN and Internet services according to the above data paths.

[0136] In addition, further, in some other embodiments, the above-mentioned SMF can also report the auxiliary anchor point UPF to CHF (CHarging Function, billing service function) after the ULCL UPF and the auxiliary anchor point UPF are selected, and add it to the billing process of the user to realize billing for the user's access to local services.

[0137] In this scenario, traffic diversion rules are distributed to the UPF, which is a combined campus ULCL and primary anchor point. Data packets that subsequently match the diversion rules are forwarded to the primary anchor point UPF and then to the local DN via the N6 interface. Other data packets are forwarded to the secondary anchor point UPF in the prefecture-level city and then to the Internet via the N6 interface. This reduces traffic detours and improves data security, ensuring that data does not leave the campus.
