    Abstract: This application provides a dial-up packet processing method. The method is applied to a dial-up packet processing system. The system includes a controller, an access gateway, a forwarding plane network element, and a control plane network element that are connected to each other. The method includes: The control plane network element receives a dial-up packet from the access gateway, where the dial-up packet is a dial-up packet sent by user equipment to the access gateway; the control plane network element sends an authentication request to an external server, where the authentication request is generated by the control plane network element based on the dial-up packet; the control plane network element receives dial-up success information sent by the external server; and the control plane network element determines the forwarding plane network element based on the dial-up success information.

    Abstract: This application provides a communication method, a CP device, and a NAT device; pertains to the field of communication technologies; and relate to a scenario of performing NAT tracing based on a CU-separated BNG. The CP device delivers, to the NAT device, an IP address assigned to a user. Under a trigger condition of receiving the IP address delivered by the CP device, the NAT device assigns a public network IP address to the user, and reports the public network IP address to the CP device. The CP device adds, to an accounting packet, the IP address assigned by the CP device and the public network IP address assigned by the NAT device, and sends the accounting packet to a RADIUS server, to report the public network IP address to the RADIUS server, so that the NAT tracing is performed on the RADIUS server.

    Abstract: This application discloses a communication method, apparatus, device, and system, and a computer-readable storage medium, and relates to the field of communication technologies. The method includes: A CP device receives a first packet that is sent by a first UP device and that carries source information of a first user terminal; searches, based on the source information of the first user terminal, a correspondence between source information of a user terminal and a location identifier of the user terminal accessing a network, to determine a first location identifier of the first user terminal accessing a network; and sends the first location identifier to a USF device.

    Abstract: Embodiments of this application provide a communication method and a related device. In the method, a control plane (CP) sends a first message to a user plane steering function (USF). The first message includes end user information, and indicates the USF to schedule an end user based on the end user information. Then, the CP determines, based on an identifier of a target UP carried in a first request message sent by the USF, to schedule the end user to the target UP. Thus, a scheduling policy of the end user is determined via the USF. The CP further processes a connection between the end user and the target UP based on the identifier of the target UP.

    Abstract: A controller receives an access request message of a to-be-served flow that is sent by a network device. The access request message includes an identifier of the to-be-served flow and an identifier of a terminal that sends the to-be-served flow. The controller determines service level information of the to-be-served flow based on the identifier of the terminal and the identifier of the to-be-served flow. The controller determines a transmission path of the to-be-served flow and a transmission path of a being-served flow based on the service level information of the to-be-served flow and service level information of the being-served flow. The controller publishes the transmission path of the to-be-served flow and the transmission path of the being-served flow to the network device.

    Abstract: This application discloses a method for controlling subscriber access to a network, a device, and a system. A control plane device receives a first access request packet of a first subscriber, determines, based on a first correspondence, a first household to which the first subscriber belongs, then determines a first user plane device based on a second correspondence, and indicates the first subscriber to access the network through the first user plane device. The control plane device allocates, to a same user plane device, a subscriber who belongs to a same household and who accesses the network, so that the same user plane device provides a broadband network access service for the subscriber who belongs to the same household and who accesses the network.
