A process of operating a first network node in a first communication network can include establishing a control plane interface between the first network node and a second network node in a second communication network. The process can further include communicating first control plane data via the control plane interface. The first control plane data can be associated with operation of a user equipment, UE, in a first communication system of the first communication network. The process can further include determining that the UE has moved to a second communication system of the first communication network. The process can further include maintaining the control plane interface between the first network node and the second network node in the second communication network. The process can further include communicating second control plane data via the control plane interface.

Embodiments of this application provide a wireless communication method and a terminal device, to flexibly judge, according to configuration information of a network device, whether a PDCP layer entity needs to re-established, thereby preventing a re-establishment operation from being performed when the PDCP layer entity does not need to be re-established, and then reducing signaling overheads. The method includes: receiving, by a terminal device, configuration information that is used to perform mobility management on the terminal device and that is sent by a network device, where the configuration information includes indication information, and the indication information is used to configure a packet data convergence protocol PDCP layer entity; and determining, by the terminal device according to the indication information, whether to re-establish the PDCP layer entity.
