    Abstract: A method for moving between communications systems and an apparatus, where the method includes: receiving, by a user equipment (UE), a first message, where the first message is used to set up or modify a first evolved packet system (EPS) bearer for the UE in the first communications system, and the first message includes first quality of service (QoS) flow information that is of the second communications system and corresponds to the first EPS bearer; storing, by the UE, the first QoS flow information; moving, by the UE, from the first communications system to the second communications system; and determining, by the UE based on a first condition, QoS flow information used by the UE in the second communications system, where the first condition includes the first QoS flow information.

    Abstract: A session establishment method includes receiving, by a mobility management function AMF entity, a first message sent by user equipment UE, where the first message carries identifier information, the identifier information is used to instruct the AMF entity to send the first message to a session management function SMF entity, and the first message is used to instruct the SMF entity to re-establish a session with the UE based on the identifier information by using a first user plane function UPF entity; and sending, by the AMF entity based on the identifier information, the first message to the SMF entity associated with the identifier information.

    Abstract: An inter-communications-system handover method implements handover of user equipment (UE) between communications systems and deletes a session incapable of being handed over, The inter-communications-system handover method includes determining, by UE, whether a first session exists in a first communications system, where the first session is capable of being handed over 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.
