Abstract: Embodiments of this application provide example media packet transmission methods, apparatuses, and systems, and relate to the field of communication technologies. One example method includes receiving, by a user plane network element, a media packet from an application server. The user plane network element determines association information corresponding to the media packet, where the association information is information associated with a client operation corresponding to the media packet. The user plane network element then sends the media packet to an access network element via a quality of service (QoS) flow corresponding to the association information.

Abstract: Embodiments of the present disclosure provide a routing control method, network device, and controller. The method may include the network device obtaining a route suppression request. The method may also include determining the second routing entry. Furthermore, the method may include setting a state of the second routing entry to a non-delivery state that is used to indicate that the second routing entry does not need to be delivered to a forwarding table. In the method, the network device may have a first routing entry and a second routing entry, an address prefix of the first routing entry is a first address prefix, an address prefix of the second routing entry is a second address prefix, a network segment to which the second address prefix belongs is a subset of a network segment to which the first address prefix belongs, and a mask in the second address prefix is greater than a mask in the first address prefix.

Abstract: This application provides a network connection configuration method and an apparatus. The method is as follows: After a terminal device obtains network configuration information of an application in the terminal device, the terminal device sends the network configuration information to a core network control plane network element, so that the core network control plane network element may determine a network connection that is of the application and is between the terminal device and the data network and that meets the network configuration information.

Abstract: Example network-based adaptive streaming media parameter adjustment methods and apparatuses are disclosed. One example method includes receiving, by an access network device, media QoS information from a session management network element, where the media QoS information includes at least two bit rate indicators and QoS requirement information corresponding to each of the bit rate indicators. The access network device determines, based on a current network condition and the media QoS information, a target bit rate indicator from the at least two bit rate indicators. The target bit rate indicator is sent to a terminal or a video server, where the current network condition meets a network requirement for transmitting streaming media data at a bit rate indicated by the target bit rate indicator.

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 disclosure relates to service packet transmission methods. In one example method, a target user plane network element receives a first uplink service packet from a source user plane, where the first uplink service packet is an uplink service packet received by the source user plane after receiving a second uplink service packet, and the second uplink service packet is the last uplink service packet from the source user plane to a source application server. The target user plane network element receives first indication information, used to indicate that sending of the first uplink service packet by the source user plane network element ends, from the source user plane network element. The target user plane network element sends, to a target AS after the first uplink service packet is sent, an uplink service packet that is from an access network device to the target user plane network element.

Abstract: This application discloses a path processing method, an apparatus, and a related computer-readable storage medium. In the method, whether there is an existing communication connection for a service flow is determined, and a service feature indicator corresponding to the existing communication connection satisfies a service feature condition required by the service flow. In a case of determining that there is the existing communication connection, a service packet is sent in the existing communication connection. In a case of determining that there is no existing communication connection, a new communication connection is established for the service flow, and a service packet is sent in the new communication connection, and a service feature indicator corresponding to the new communication connection satisfies the service feature condition required by the service flow.
