The network device in the network device or the network device in the future evolved PLMN network is not limited in this embodiment.

FIG. 1 is a schematic diagram of an application scenario of an embodiment of the present application. The communication system in FIG. 1 may include a terminal device 10 and a network device 20. The network device 20 is configured to provide communication services for the terminal device 10 and access the core network. The terminal device 10 accesses the network by searching for synchronization signals, broadcast signals, and the like transmitted by the network device 20, thereby performing communication with the network. The arrows shown in FIG. 1 may represent uplink/downlink transmissions by a cellular link between the terminal device 10 and the network device 20.

In eLTE, the terminal device first uses the first PDCP in the initial connection establishment process, and then needs to be configured as the second PDCP before sending the SMC message, where the first PDCP may be an LTE PDCP and the second PDCP may be an NR PDCP. The flow of switching PDCP in the prior art will be schematically illustrated below with reference to FIG. 2 . Specifically, the following steps are included:

S101. The terminal device sends a Radio Resource Control (RRC) request to the network device.

S102. The network device sends an RRC connection setup message to the terminal device.

S103. When the core network device that provides the service for the terminal device is switched to the core network in the NR, the terminal device sends an RRC connection establishment complete message based on the LTE PDCP to the network device, where the network device performs the RRC connection setup complete message based on the LTE PDCP.
