Abstract: Embodiments of this application provide a packet transmission method, a communication apparatus, and a communication system. A target transport layer proxy network element establishes a fourth transport layer connection based on a first context of a source transport layer proxy network element, where the first context is a context about packet transmission of the source transport layer proxy network element on a first path. If the target transport layer proxy network element receives first indication information, and the first indication information indicates that application context migration between a first application server and a second application server is completed, the target transport layer proxy network element performs transport layer processing on a packet on a second path based on a second context of the target transport layer proxy network element, and transmits, on the second path, a packet obtained through the transport layer processing. Hence, a packet loss can be avoided.

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: This application provides a communication method, wherein a user plane path between a terminal and a user plane gateway includes a first link and a second link, the first link is a link between the terminal and an access network device, and the second link is a link between the access network device and the user plane gateway. The method comprises: obtaining packet loss statuses of a service flow on the first link and the second link; determining a quantity of consecutive lost packets of the service flow on the user plane path based on the packet loss statuses of the service flow on the first link and the second link; and when the quantity of consecutive lost packets of the service flow on the user plane path reaches a first threshold, triggers enabling of a high-reliability transmission mechanism for the service flow.

Abstract: This application provides a multipath transmission method and a communication apparatus. In this solution, data of a remote terminal is transmitted through two paths, to improve data transmission reliability of the remote terminal. The solution includes: A user plane function node receives second information from a session management function node; and the user plane function node replicates, based on the second information to the second communication path, data that is of the remote terminal and that is transmitted through a first communication path. The first communication path is a first session of the remote terminal, and the second communication path includes a second session of a relay terminal corresponding to the remote terminal and a sidelink between the relay terminal and the remote terminal.

Abstract: Embodiments of this application provide a message forwarding method and an apparatus, so that a message for joining a multicast group is sent to a multicast user plane network element, and the multicast user plane network element is triggered to establish a tunnel for transmitting multicast data between the multicast user plane network element and an application server. The method may include: a multicast session management network element receives the message that indicates that a terminal is joining the multicast group; and when the terminal is the 1st terminal the multicast group, sends, to the multicast user plane network element, a message that requests to establish the tunnel for transmitting the multicast data between the multicast user plane network element and the application server.

Abstract: A domain name access method and a device are described. As described herein, a domain name server (DNS) server performs resolution on a domain name requested by the terminal device. The DNS server may then send an internet protocol (IP) address of an application server obtained through the resolution and use condition information to the terminal device. With this, communication efficiency of the terminal device can be improved, and waste of transmission resources in a communications system is also avoided.
