Example communication methods and apparatus in a wireless network are described. One example communication method includes establishing dual connections to a first access network device and a second access network device by a terminal device. A connection that is between the terminal device and the first access network device and that is included in the dual connections is a radio resource control (RRC) connection. The terminal device receives first configuration information sent by the first access network device. The first configuration information includes signaling radio bearer (SRB) configuration information of the second access network device and a trigger condition for using the SRB configuration information. When the trigger condition is met, the terminal device uses the SRB configuration information of the second access network device to establish an RRC connection to the second access network device.
