1. A communication method, comprising:
receiving, by a terminal device comprising a processor, indication information from a master node, wherein
the indication information is used to indicate that a key used for signaling transmission performed between the terminal device and a first secondary node by using a second signaling radio bearer (SRB) is a first key,
the indication information is carried in a radio resource control (RRC) reconfiguration message,
the RRC reconfiguration message is used to cause the terminal device to add the first secondary node or to be handed over from a second secondary node to the first secondary node,
the first key is used for signaling transmission performed between the terminal device and the master node by using a first SRB, and
the first secondary node and the master node share one central unit; and
determining, by the terminal device, based on the indication information, that the first key is used for signaling transmission performed between the terminal device and the first secondary node by using the second SRB.
