Abstract: A communication method and apparatus includes: An access gateway function network element sends a session establishment request message of a terminal to a session management function network element. The session management function network element sends, to the access gateway function network element, at least one of a session identifier and an address of the terminal that correspond to an established session. The access gateway function network element obtains virtual interface information corresponding to the identifier of the established session. The access gateway function network element further sends the virtual interface information and the at least one of the session identifier and the address of the terminal to the terminal, so that the terminal establishes a first association relationship between the virtual interface information and the at least one of the session identifier and the address of the terminal.

Abstract: In the method, a terminal device may send first indication information on a first uplink resource based on information about a spatial relation parameter, to indicate that a link failure occurs in a ith cell in N second cells. The information about the spatial relation parameter is information about a spatial relation parameter used to send a channel and/or a signal of a first cell, and the first uplink resource is an uplink resource of the first cell. Therefore, the network device does not need to configure a plurality of uplink resources that are associated with a plurality of reference signal resources of a second cell and that are used to indicate that a link failure occurs in the second cell, thereby reducing resource overheads.
