    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: Embodiments of this application relate to the communications field, and disclose an inter-communications-system moving method, a device, and a system, to implement moving of UE between communications systems and delete a session incapable of being transferred. The 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.

    Abstract: Embodiments of the present invention relate to the field of communications technologies, and in particular, to a method, an apparatus, and a system for establishing a session, to resolve a problem in the prior art that efficiency is low because an AMF entity needs to reselect an SMF entity when forwarding a first message. The 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. The embodiments of the present invention are applied to a system for establishing a session.

    Abstract: A circuit switched fallback (CSFB) method and apparatus, where a user equipment (UE) initiates a calling process, receives a first request from a first communications system, and after the UE is transferred to a second communications system and before the UE receives a first message from the second communications system, the UE determines that a voice call bearer cannot be set up in the second communications system, and initiates a CSFB in the second communications system, where the first message is used by the UE to determine that a call request has failed.

    Abstract: This application discloses a network access method and device. The method includes: receiving, by a first management entity, a first request message sent by a first terminal, where the first request message includes at least a first identifier of a second terminal; determining, by the first management entity based on a first condition, whether the second terminal can access a network by using the first terminal, where the first condition includes at least that the first identifier of the second terminal belongs to a list of at least one terminal having a trust relationship with the first terminal, and the list includes at least a first identifier of the at least one terminal having the trust relationship with the first terminal. Legality of access by a wearable device to a network by using a user terminal can be authenticated by using the method and device in this application.

    Abstract: This application provides a data route selection method and apparatus, and relates to the field of communications technologies, so as to resolve a problem of an excessively long transmission delay for an application program that initiates a data transmission request relatively later. The data route selection method includes: detecting, by a terminal, that information about an application matches a traffic descriptor; determining, by the terminal, a first route selection components for the application; and routing, by the terminal, traffic of the application on a first protocol data unit PDU session. The first PDU session matches the first route selection components. This application is applicable to a terminal.

    Abstract: Embodiments of the present invention relate to the field of communications technologies, and disclose a call termination method, an application processor, and a modem. In this solution, the application processor receives a hang-up instruction and sends a first message to the modem according to the hang-up instruction, where the first message is used to trigger the modem to directly terminate a call. The modem may terminate the call in a timely manner according to the first message. Therefore, a time consumed in call termination is reduced and efficiency is improved.
