Abstract: Embodiments of the present disclosure provide a policy control method and system, a network element, and a storage medium. A control plane network element establishes, for UE, a first DN connection that uses a first forwarding plane network element as an anchor. The method includes: when the control plane network element receives a handover notification message for the UE and determines that a second forwarding plane network element serves the UE, or when the control plane network element establishes, for the UE, a second DN connection that uses a second forwarding plane network element as an anchor, the control plane network element updates a forwarding path of the first DN connection, so that an updated forwarding path of the first DN connection passes through the second forwarding plane network element, and the second forwarding plane network element performs policy control on a packet on the first DN connection.

Abstract: A session processing method includes determining, by a processor that a first application is not associated with a session parameter of a first session when starting the first application. The method also includes transmitting data of the first application through the first session in response to obtaining indication information. The indication information indicates that the session parameter of the first session can satisfy a session parameter requirement of the first application.

Abstract: The present disclosure relates to quality of service (QoS) information notification methods, devices, and systems. In one example method, a user plane network element obtains a first QoS notification, where the first QoS notification includes first QoS information used to indicate QoS of a target service. The user plane network element sends first indication information to an application network element to which a QoS notification needs to be reported, where the first indication information is used to indicate a second QoS notification, the second QoS notification includes second QoS information of the target service, and the first QoS notification is the same as the second QoS notification, or the second QoS notification is determined based on the first QoS notification.

Abstract: This application provides a data transmission method and device. In a process in which a terminal device is handed over from a source access network device to a target access network device, the source access network device processes buffered packet data convergence protocol (PDCP) data, so that when a forwarding tunnel is a tunnel of a session granularity or a group granularity, the target access network device accurately forwards data in the handover process. The method includes: encapsulating, by a source access network device, indication information in an encapsulation header of PDCP data, where the indication information is used to indicate a radio bearer used for sending the PDCP data by a target access network device; and sending, by the source access network device to the target access network device, the PDCP data in which the indication information is encapsulated.
