1. A source network device, comprising:
a transceiver;
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the source network device to:
obtain configuration information of a sounding reference signal (SRS) of a terminal device;
send the configuration information of the SRS to a target network device and the terminal device, wherein the configuration information of the SRS is for configuring a resource used by the terminal device to send the SRS, and is for configuring the target network device to monitor the SRS on the resource;
receive signal quality information of the SRS detected by a first cell of the target network device from the target network device, wherein the first cell is a cell controlled by the target network device, the first cell is in an energy-saving state that is configured not to send a synchronization signal/physical broadcast channel block (SSB); and
send a first message to the target network device, wherein the first message requests to hand over the terminal device to the first cell and the first message comprises indication information to indicate the target network device to send an SSB corresponding to the first cell.
