    Abstract: A session processing method related to the field of wireless communications technologies is provided. The method discloses: obtaining, by user equipment (UE), session type information, where the session type information is used to indicate a type of a first session; and when a first application triggers a first service, determining, by the UE based on the session type information, whether a create session request needs to be initiated for the first service. According to the solutions provided in embodiments, before the create session request is initiated, the UE may determine whether to reuse a created session or create a new session. In this way, for a service that can reuse a created session, no new session needs to be created, thereby reducing signaling exchange between the UE and a network side.

    Abstract: Embodiments of the present disclosure provide a charging measurement method, apparatus, and system. The method may include obtaining, by a control plane network element, a traffic flow charging parameter, the traffic flow charging parameter is an online charging parameter or an offline charging parameter. The method may also include determining a charging measurement parameter based on the traffic flow charging parameter, a charging measurement parameter determined based on the online charging parameter and a charging measurement parameter determined based on the offline charging parameter are charging measurement parameters in one charging measurement parameter set. Furthermore, the method may include sending a first message to a forwarding plane network element, where the first message carries the charging measurement parameter set and a traffic flow identifier, and the first message is used to trigger the forwarding plane network element to perform, based on the charging measurement parameter set, charging measurement on a traffic flow indicated by the traffic flow identifier.

    Abstract: Embodiments of the present disclosure relate to 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: The present invention provides a packet processing method and an apparatus. The method includes: determining a to-be-installed flow entry and packet sending information; and sending, to a switch, a flow entry installation message carrying the to-be-installed flow entry and the packet sending information, so that the switch obtains the to-be-installed flow entry and the packet sending information from the flow entry installation message, installs the flow entry, and sends a packet according to the packet sending information. In the present invention, a controller sends a flow entry installation message carrying a to-be-installed flow entry and a packet sending message, where the to-be-installed flow entry and a to-be-sent packet are simultaneously sent, so that a switch simultaneously receives the to-be-installed flow entry and the to-be-sent packet, and performs flow entry installation and packet sending, thereby reducing unnecessary signaling exchange, and improving efficiency of flow entry installation and packet sending.

    Abstract: A method and an apparatus for forwarding a packet, where a first network virtualization edge (NVE) receives a first packet sent by a first tenant end system (TES), where a destination Internet Protocol (IP) address of the first packet is an IP address of a second TES, a destination media access control (MAC) address of the first packet is a gateway MAC address corresponding to the first NVE. The first NVE acquires an access virtual network identifier (VN ID) and a layer 3 virtual private network (VPN) instance identifier of the first TES, and searches a routing and forwarding table, to obtain an entry corresponding to the IP address of the second TES. Then the first NVE encapsulates the first packet into a network virtualization overlays (NVO3) packet according to the entry, and forwards the NVO3 packet to a second NVE to forward to the second TES.
