Abstract: A service transmission method and apparatus are provided to establish a connection between an access and mobility management function network element and a secondary base station, when a master base station is not capable of continuing to provide a service for a terminal device. In an embodiment, an access and mobility management function network element determines that a master base station is not capable of continuing to provide a service for a terminal device. The access and mobility management function network element sends a mobility management context of the terminal device to a secondary base station, where the mobility management context is used by the secondary base station to perform mobility management on the terminal device. Therefore, a signaling connection between the access and mobility management function network element and the secondary base station can be quickly established, thereby ensuring service transmission and improving user experience.

Abstract: A control method for collecting traffic statistics includes a control node obtains a statistics collection instruction, where the statistics collection instruction is used to instruct to collect traffic statistics of a target data flow, generates a traffic statistics collection policy according to the statistics collection instruction, where the traffic statistics collection policy includes a matching identifier of the target data flow, a first command, and a second command, and sends the traffic statistics collection policy to a forwarding node. The first command is used to instruct the forwarding node to set a traffic identifier for the target data flow based on the matching identifier, the second command is used to instruct the forwarding node to add traffic generated by a target packet to a traffic statistics collection result corresponding to the traffic identifier which is used to describe the traffic of the target data flow.

Abstract: A domain name system query method in which: a first network element receives a DNS query request including a first domain name from a terminal apparatus; the first network element sends first request information which comprises location information of the terminal apparatus and the first domain name to a second network element; the second network element determines, based on the first request information, an IP address and feeds back the IP address to the first network element; and the first network element sends the IP address to the terminal apparatus. When a terminal apparatus performs domain name query, a core network element determines an IP address of an application server based on location information of the terminal apparatus and a queried domain name. In this way, the terminal apparatus obtains an IP address of an application server close to the terminal apparatus, thereby improving service access efficiency of the terminal apparatus.

Abstract: According to a communication method and a communications apparatus, in a process in which an access network device serving a terminal is handed over from a source access network device to a target access network device, a user plane function network element may transmit first information to the source access network device. The first information is used to indicate that the user plane function network element bicasts downlink packets to the source access network device and the target access network device, so that after determining that a data packet received before the first information is sent to the terminal, the source access network device triggers an air interface handover, to avoid a packet loss in a handover process, or so that the source access network device synchronizes a PDCP SN of the source access network device with a PDCP SN of the target access network device.

Abstract: A data buffering method including: a session management function (SMF) interacting with a first user plane function (UPF1) and a second UPF2, such that the UPF1 sends first downlink data of a first session to an access network device via UPF2, where UPF1 is an anchor of the first session; and the SMS releasing UPF2 in a procedure in which a terminal device enters an idle state and a transmission resource associated with the first session in an access network is released, where UPF1 buffers incoming second downlink data of the first session. After the terminal device is switched to a connected state, both a transmission path of incoming third downlink data of the first session and that of the buffered second downlink data pass through UPF1, UPF3, the access network device, and the terminal device successively.
