Abstract

Provided are a wireless communication method, a terminal device and a network device. The method comprises: a target terminal device sending a first request to a network device, wherein the first request is used to request the migration of a target service from a first terminal device to a second terminal device; and the target terminal device is the first terminal device or the second terminal device. In the embodiments of the present application, the target terminal device can send the first request to the network device to request the migration of the target service from the first terminal device to the second terminal device. That is, the introduction of the first request helps the network device to perceive the requirement for the cross-terminal-device migration of the target service so as to optimize subsequent processes on the basis of the requirement. Compared with that during conventional cross-terminal-device migration of a target service, the network device is unable to perceive the requirement for the cross-terminal-device migration of the target service, and is thus unable to optimize the subsequent processes on the basis of the requirement, an improvement in the user experience is facilitated.

Description

TECHNICAL FIELD The present disclosure relates to the technical field of communications, and more particularly, to methods for wireless communication, terminal devices, and network devices. BACKGROUND With the advancement of science and technology and the improvement of living standards, a user usually has multiple terminal devices. In some scenarios, users often switch between multiple terminal devices. For example, if the user runs a certain service (also referred to as a "target service") on a first terminal device and then needs to switch to a second terminal device to run the service, the user needs to terminate the operation of the target service on the first terminal device first, and then start the target service on the second terminal device. This way of switching between terminal devices will lead to an increased sense of stagnation in the target service, and degrade user experiences.
