Title:
WIRELESS COMMUNICATION METHOD, COMMUNICATION APPARATUS AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/155853
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a wireless communication method, a communication apparatus and a communication system. The method comprises: a mobility management network element receiving a handover request from a source access network device, wherein the handover request comprises an identifier of a first session, the first session corresponds to a first network slice, and the first session is used to transmit a data packet of a first application; when it is determined that a target access network device does not support the first network slice, determining a second network slice supported by the target access network device; and triggering the target access network device to transmit the data packet of the first application by means of the second network slice. In this solution, after a terminal device moves out of the coverage range of a first network slice, when a target access network device does not support the first network slice corresponding to a first session, a second network slice supported by the target access network device is selected, such that the target access network device transmits, by means of the second network slice, the data packet, originally transmitted by means of the first session, of the first application, so as to ensure service continuity and facilitate the improvement of the user experience.
