Abstract: Embodiments of this application provide a multicast communication method that includes: receiving, by a user plane function network element, a multicast packet, where the multicast packet includes a multicast address; matching, by the user plane function network element, the multicast packet with a packet detection rule PDR on the user plane function network element; and if the multicast packet successfully matches a first PDR, and the first PDR indicates to carry on matching another PDR, carrying on, by the user plane function network element, matching the multicast packet with another PDR. Optionally, the another PDR is a PDR whose priority is not higher than that of the first PDR.

Abstract: This application provides a deregistration method and a communication apparatus. The method may include: receiving a first message from a first mobility management network element, where the first message carries first information which is onboarding indication information or time information of a first deregistration timer on the first mobility management network element; starting a second deregistration timer based on the first information; and upon expiry of the second deregistration timer, triggering a deregistration procedure, to deregister a terminal device from a network. In this application, after mobility management network element redirection, the deregistration timer can still be started on the new mobility management network element that supports onboarding. Upon expiry of the deregistration timer, the deregistration procedure is triggered to deregister the terminal device from the network, to prevent the terminal device from camping on the network indefinitely.

Abstract: A registration processing method and an apparatus are disclosed herein to enable the network to distinguish between different registration processing types. The method includes: identifying, by a user equipment, UE, a registration type when registering into a network; reporting, by the UE, a registration processing type information corresponding to the identified registration type to a network-side network element during registering into the network. The UE reports the registration processing type information to the network in the process of registering into the network, and therefore, the network distinguishes between different registration processing types accordingly.

Abstract: Embodiments of this application provide a communication method, a device, and a system, to resolve an out-of-order problem caused by per-packet traffic splitting. The method includes: determining, by a sending device, a sequence identifier of a to-be-transmitted data packet and an identifier of a first link for transmitting the data packet; and sending, by the sending device, the data packet to a receiving device, where a header of the data packet includes the identifier of the first link and the sequence identifier, the identifier of the first link is used to identify the first link, and the sequence identifier is used to identify a sending order of the data packet over the first link or in a link group to which the first link belongs.

Abstract: A routing rule configuration method and a communications apparatus are provided. In the method, after receiving a PDU session establishment request from a first terminal, a session management function network element generates, based on first information including information used to indicate to forward a data packet through an N6 interface, a routing rule used to indicate to send the data packet of a 5G LAN group to which the first terminal belongs to the N6 interface or discard the data packet. The session management function network element can determine a routing rule for an N6-based forwarding manner based on the first information.
