Title: SWITCHING METHOD, TERMINAL DEVICE AND NETWORK DEVICE
Abstract:
Provided in the present application are a switching method, a terminal device, and a network device, the switching method comprising: a first network node learning that a terminal device must perform switching, switching being a switch from a second network node to a third network node, or switching being a switch from a first cell of the second network node to a second cell of the second network node; the first network node comprises at least one from among a packet data convergence protocol layer, a service data adaptation layer, and a radio resource control function, while the second network node and the third network node comprise at least one from among a radio link layer control protocol layer, a media intervention control layer, and a physical layer function; the first network node sending a switch command to the terminal device, the switch command being used for instructing the terminal device to perform switching. The switching method in an embodiment of the present application may ensure that the terminal device performs normal switching when part of the functions of the network device are separated into different network nodes.
