US 2021/0345187 A1 · Inter-Communications-System Moving Method, Device, and System

Abstract

An inter-communications-system moving method includes determining, by user equipment UE, whether a first session exists in a first communications system, where the first session is capable of being transferred from the first communications system to a second communications system; and sending, by the UE, a first message to a first core network device of the second communications system when determining that the first session exists, where the first message is used to establish a second session in the second communications system, and the second session corresponds to the first session.

Claims20

Dependent claims

An apparatus comprising:

a processor;
and
a memory coupled to the processor, wherein the memory comprises instructions that, when executed by the processor, cause the apparatus to:
determine whether the apparatus has a first protocol data unit (PDU) session which corresponds to at least one of a quality of service (QoS) parameter of a second communications system or a bearer identifier of the second communications system, wherein the apparatus has at least one PDU session;
and
perform, in response to determining that the apparatus has the first PDU session, a tracking area update in the second communications system.
