Abstract: A communication method and apparatus are provided. A session management function network element receives first information from an edge application server discovery function network element, where the first information comprises internet protocol (IP) address information of N edge application servers (EASs), and N is an integer greater than or equal to 2. The session management function network element determines an EAS IP address information set based on the IP address information of the N EASs, where the EAS IP address information set comprises IP address information of M EASs, the IP address information of the M EASs corresponds to a same data network access identifier (DNAI), and M is an integer less than or equal to N. The session management function network element sends the EAS IP address information set to the edge application server discovery function network element.

Abstract: This application provides example path switching methods, example communication apparatuses, and example communication systems. One example method includes obtaining, by a session management network element, a context of a first transport layer connection, where the first transport layer connection is between a source transport layer proxy network element and a terminal device. In response to determining that a protocol data unit (PDU) session anchor for the terminal device needs to be changed, the session management network element can send the context of the first transport layer connection to a target transport layer proxy network element, where the context is used to establish a third transport layer connection between the target transport layer proxy network element and the terminal device.

Abstract: The present disclosure relates to network slice access control methods. One example method includes receiving, by an access and mobility management function network element, first information from a session management function network element, where the first information is associated with an authentication failure of a network slice, and sending, by the access and mobility management function network element, second information to a terminal device based on the first information, where the second information is used to reject access of the terminal device to the network slice.

Abstract: This application provides a downlink transmission method. A session management network element obtains duration, namely, a first delay, between an expected moment at which a downlink service packet arrives at an access network element and an estimated moment at which the downlink service packet arrives at the access network element, the expected moment is within a first scheduling window, and a next scheduling window adjacent to the first scheduling window is a downlink scheduling window. Then, the session management network element sends the first delay to an application network element, where the first delay is used by an application server to determine a second moment at which the downlink service packet is sent, and a moment at which the downlink service packet sent at the second moment arrives at the access network element is within the first scheduling window.
